AIM—To investigate the
effect of several types of congenital heart disease (CHD) on nutrition
METHODS—The prevalence of malnutrition and growth
failure was investigated in 89 patients with CHD aged 1−45 months.
They were grouped according to cardiac diagnosis: group aP (n = 26),
acyanotic patients with pulmonary hypertension; group ap (n = 5),
acyanotic patients without pulmonary hypertension; group cp (n = 42),
cyanotic patients without pulmonary hypertension; and group cP
(n = 16), cyanotic patients with pulmonary hypertension. Information
on socioeconomic level, parental education status, birth weight and
nutrition history, number of siblings, and the timing, quality, and
quantity of nutrients ingested during weaning period and at the time of
the examination were obtained through interviews with parents.
RESULTS—There was no
significant difference between groups in terms of parental education
status, socioeconomic level, duration of breast feeding, and number of
siblings (p > 0.05). Group cP patients ingested fewer nutrients for
their age compared to other groups. 37 of the 89 patients were below
the 5th centile for both weight and length, and 58 of 89 patients were
below the 5th centile for weight. Mild or borderline malnutrition was
more common in group aP patients. Most group cp patients were in normal
nutritional state, and stunting was more common than wasting. Both
moderate to severe malnutrition and failure to thrive were more common in group cP patients.
with CHD are prone to malnutrition and growth failure. Pulmonary
hypertension appears to be the most important factor, and cyanotic
patients with pulmonary hypertension are the ones most severely
affected. This study shows the additive effects of hypoxia and
pulmonary hypertension on nutrition and growth of children with CHD.
Vascular endothelial growth factor (VEGF), platelet derived endothelial cell growth factor/thymidine phosphorylase (PD-ECGF/TP) and leptin are known as potent angiogenic factors The objective of the study was to evaluate these angiogenic factors VEGF, PD-ECGF/TP and leptin in children with congenital heart disease (CHD) and the factors that lead to angiogenesis in such cases.
Sixty CHD children were studied and divided into two groups (n = 30); cyanotic-CHD (C-CHD) and acyanotic-CHD (A-CHD). Twenty five healthy children were included as controls.
Significantly higher serum levels of VEGF, PD-ECGF/TP activity and leptin were detected in patients with CHD, particularly in patients with C-CHD. CHD patients with SpO2 <90%, pulmonary hypertension (PH), severe pulmonary stenosis (PS), detectable collaterals, cardiomegaly and/or heart failure showed significantly higher levels of these factors than those with higher SpO2 or those without these findings.
Hypoxia, PH and PS are important factors that lead to harmful angiogenesis. However, angiogenesis could be essential in some cases of CHD as coarctation of aorta to enhance renal perfusion. This may provide new ways for therapeutic strategies aiming at reducing or promoting angiogenesis in CHD to improve patient's outcome.
Major progress has been made over the last 30 years in reducing the prevalence of malnutrition amongst children less than 5 years of age in developing countries. However, approximately 27% of children under the age of 5 in these countries are still malnourished. This work focuses on the childhood malnutrition in one of the biggest developing countries, Egypt. This study examined the association between bio-demographic and socioeconomic determinants and the malnutrition problem in children less than 5 years of age using the 2003 Demographic and Health survey data for Egypt. In the first step, we use separate geoadditive Gaussian models with the continuous response variables stunting (height-for-age), underweight (weight-for-age), and wasting (weight-for-height) as indicators of nutritional status in our case study. In a second step, based on the results of the first step, we apply the geoadditive Gaussian latent variable model for continuous indicators in which the 3 measurements of the malnutrition status of children are assumed as indicators for the latent variable “nutritional status”.
Based on data generated from 180 randomly selected households with children age under five years old in Aysaita district of Afar region of Ethiopia, this study explored prevalence of malnutrition and scrutinized household characteristics, maternal characteristics, specifics of the child and economic variables associated with child malnutrition. The height-for-age Z-scores (HAZ), weight-for-height Z-scores (WHZ) and weight-for-age Z-scores (WAZ) were used to measure the extent of stunting, wasting and underweight, respectively. The results revealed that prevalence of long term nutritional imbalance and malnutrition status indicator (i.e. stunting) was 67.8%. The short term measure (wasting) was found to be 12.8% and underweight was found to be 46.1%. Moreover, children in households which are headed by women, and characterized by more dependency ratio, less access to assets, health services and institutions are more likely to be undernourished.

There is a dearth of information on the health of pastoral Fulani children living in southwestern Nigeria. These are fully settled pastoralists whose economy are centred on cattle and farming. In other to monitor and plan appropriate nutritional intervention for their children, a cross-sectional study was carried out to determine the prevalence of malnutrition of pastoral Fulani children.
Fulani's children aged 6 months to 15 years, living in 61 settlements in Kwara, Ogun and Oyo States in Southwestern Nigeria participated in the study. Heights and weights of 164 girls and 167 boys were measured. Their anthropometric indices, height-for-age (HA), weight-for-height (WH), and weight-for-age (WA) Z-scores determined. The prevalence of stunting (HAZ < -2), wasting (WHZ < -2) and underweight (WAZ < -2) was 38.7%, 13.6%, and 38.7%, respectively when compared to the reference NCHS/WHO standard used for defining stunting, wasting and underweight. Boys were more malnourished than the girls were, but this was not significant (stunting: χ2 = 0.36; df = 1; P = 0.54); (underweight: χ2 = 1.10; df = 1; P = 0.29); and (wasting: χ2 = 0.00; df = 1; P = 0.98) The mean of Z-scores of Height-for-age, Weight-for-age and Weight-for-height in children were -1.502, -1.634 and -0.931 respectively. The SD was 1.52, 1.09 and 1.20 respectively. Using WHO Malnutrition Classification systems, 38.7% of the children were found to be malnourished.
These results indicate high prevalence of malnutrition among settled pastoral Fulani children, possibly due to changes in food habits and lifestyle occasion by the transition from nomadic to sedentary living. We suggest the inclusion of Fulani's settlements in nutritional intervention for these areas.
Malnutrition is one of the important health problems throughout the world, particularly in developing countries, which has undesirable effects on mental and physical health of children. The aim of this study was to find out the prevalence of malnutrition in children under 6 years old in Privince South Khorasan, Iran, in 2007.
This cross sectional and descriptive analytical study was conducted on children under 6 years old in South Khorasan Iran, belonging to six urban and rural regions applying multistage cluster sampling methodology. Data were collected through measuring weight and height, structural questionnaires Anthropometric Nutrution Indicators Survey, and face-to-face interviews with mothers. Malnutrition was measured on the basis of the indices underweight, wasting and stunting. The obtained data was analyzed by means of chi-square test in the packages SPSS and EPI-Info 2000, taking α= 0.05 as the significant level.
Out of 1807 children 51.7% were males, 52.2% living in urban areas, and 37% were under 24 months old. Weight index was normal in 52.2% children, 34.4% lightly underweight, 11.7% moderately underweight and 1.2% severely underweight. Prevalence of underweight had a significant relationship to habitation, mothers' job and parents' education level. According to stunting criteria, 55% were normal, 28.4% lightly stunted 12.7% were moderate, and 3.9% severe stunted. Stunting also had a significant relationship to habitation, age, mother's job, and parents' level of education. Wasting criteria showed that 67.8% were normal 24.7% light, 5.9% moderate and 1.6% had severe wasting. This had a significant relationship to sex and habitation.
Prevalence of malnutrition was in children and its relationship to socioeconomic variables, measures such as increasing parents' education - especially mothers' knowledge - constancy of breast feeding until the age of 2 years, and promoting nutrition status of children under 6 years are recommended.

No information exists on the nutritional status of primary school children residing in Makurdi, Nigeria. It is envisaged that the data could serve as baseline data for future studies, as well as inform public health policy. The aim of this study was to assess the prevalence of malnutrition among urban school children in Makurdi, Nigeria.
Height and weight of 2015 (979 boys and 1036 girls), aged 9-12 years, attending public primary school in Makurdi were measured and the body mass index (BMI) calculated. Anthropometric indices of weight-for-age (WA) and height-for-age (HA) were used to estimate the children's nutritional status. The BMI thinness classification was also calculated.
Underweight (WAZ < -2) and stunting (HAZ < -2) occurred in 43.4% and 52.7%, respectively. WAZ and HAZ mean scores of the children were -0.91(SD = 0.43) and -0.83 (SD = 0.54), respectively. Boys were more underweight (48.8%) than girls (38.5%), and the difference was statistically significant (p = 0.024; p < 0.05). Conversely, girls tend to be more stunted (56.8%) compared to boys (48.4%) (p = 0.004; p < 0.05). Normal WAZ and HAZ occurred in 54.6% and 44.2% of the children, respectively. Using the 2007 World Health Organisation BMI thinness classification, majority of the children exhibited Grade 1 thinness (77.3%), which was predominant at all ages (9-12 years) in both boys and girls. Gender wise, 79.8% boys and 75.0% girls fall within the Grade I thinness category. Based on the WHO classification, severe malnutrition occurred in 31.3% of the children.
There is severe malnutrition among the school children living in Makurdi. Most of the children are underweight, stunted and thinned. As such, providing community education on environmental sanitation and personal hygienic practices, proper child rearing, breast-feeding and weaning practices would possibly reverse the trends.
The aim of this prospective study was to evaluate the proportion of children with delayed recognition of congenital heart disease (CHD).
Of the 744 children with CHD primarily diagnosed during a 10 year period in one hospital, the patients were identified where the diagnosis of CHD was established with a significant delay.
Sixty six patients (8.9%) had delayed diagnosis of CHD. Among patients with cyanotic CHD, 10.4% (7 of 67 cases) were referred after they had initially been discharged home from the birth clinic. Among patients with acyanotic CHD, 8.7% (59 of 677) of all children and 35.1% (59 of 168) of the children who required surgery or interventional catheterisation were referred at an age where elective repair should have already been performed or needed immediate treatment because of their haemodynamic status. Of the 66 patients with delayed diagnosis, one infant with cor triatriatum died at admission because of delayed referral and 10 children had severe complications: preoperative cardiogenic shock in seven cases of aortic coarctation and one case of endocardial fibroelastosis, pulmonary hypertensive crisis in one child after delayed repair of a ventricular septal defect, and infectious endocarditis after dental care in a teenager with undiagnosed moderate aortic stenosis, who required Ross operation a few months later.
Discussion and conclusion
A substantial proportion of CHD was detected with relevant delay. In all cases of late diagnosis, clinical cardiac findings were present that should have alerted the physician on the possible presence of underlying CHD.

Protein-energy malnutrition is one of the most important public health problems in Iran. It not only accounts for more than half of child mortality but can also produce somatic and mental impairment in survivors. The main aim of this study was to identify risk factors for protein-energy malnutrition in children under 6 years of age in Namin city.
This was a population-based, multicenter case-control study. Seventy-six children with malnutrition and 76 children without malnutrition were randomly recruited for case and control groups. The prevalence of risk factors in the two groups was compared. Data were gathered from a health center database and interviews with mothers and health workers. The Wilcoxon signed-rank test and logistic regression were used for data analysis.
Female gender, poverty, short maternal height, and use of unhygienic latrines in the home were significantly associated with childhood malnutrition (P < 0.05).
The results of this study indicate four main factors (poverty, small maternal height, female gender, and absence of hygienic latrines in the home) as underlying factors in malnutrition of children under the age of 6 years.

Background. Growth failure is a common feature of children with human immunodeficiency virus (HIV) infection. Malnutrition increases mortality and may
impair the response to antiretroviral treatment. Objective. Our objective was to describe the prevalence of stunting, underweight, and wasting in HIV-infected children in south India and to assess the utility of these
parameters in predicting immune status. Methodology. In this cross-sectional study, anthropometric measurements and CD4 counts were performed on 231 HIV-infected children. Z scores for height for age, weight
for age, and weight for height were correlated with CD4 cell counts and receiver operating
characteristic curves plotted. Results. Prevalence of underweight was 63%, stunting 58%, and wasting 16%, respectively. 33–45% of children were moderately or severely malnourished even at CD4
>25%; sensitivity and specificity of stunting or underweight to predict HIV disease
severity was low. Conclusions. Undernutrition and stunting are common among HIV-infected children at
all stages of the disease in India. Early and aggressive nutritional intervention is required, if long-term outcomes are to be improved.
BACKGROUND AND OBJECTIVE:
There is no published information on the prevalence of malnutrition in Saudi Arabia. The objective of this study was to establish the prevalence data.
The prevalence of nutritional indicators in the form of underweight, stunting, and wasting in a national sample of children younger than 5 years of age was calculated using the new WHO standards as reference. Calculations were performed using the corresponding WHO software. The prevalence of moderate and severe underweight, wasting and stunting, was defined as the proportion of children whose weight for age, weight for height, and height for age were below –2 and –3 standard deviation scores, respectively.
The number of children younger than 5 years of age was 15 516 and 50.5% were boys. The prevalence of moderate and severe underweight was 6.9% and 1.3%, respectively. The prevalence of moderate and severe wasting was 9.8% and 2.9%, respectively. Finally, the prevalence of moderate and severe stunting was 10.9% and 2.8%, respectively. The prevalence was lower in girls for all indicators. Comparison of the prevalence of nutritional indicators in selected countries demonstrates large disparity with an intermediate position for Saudi Arabia.
This report establishes the national prevalence of malnutrition among Saudi children. Compared to data from other countries, these prevalence rates are still higher than other countries with less economic resources, indicating that more efforts are needed to improve the nutritional status of children.
To evaluate the relative effect of cyanosis, surgical interventions and family processes on neuropsychological and behavioural outcomes in 4‐year‐old survivors of serious congenital heart disease (CHD).
90 children with a range of cyanotic and acyanotic conditions, who underwent either corrective or palliative surgery, completed a neuropsychological and behavioural evaluation. Families of participants were also profiled by evaluation of maternal mental health, worry, social support, parenting style and family functioning.
Compromised neuropsychological outcomes were associated with a combination of cyanotic conditions and open‐heart surgery, but this was not exacerbated by having a complex, palliative, status. Both cyanotic and acyanotic conditions were associated with specific sensorimotor delays, regardless of method of the correction. Only children with complex conditions and palliative interventions seemed at risk of poor behavioural outcomes; indeed, children with cyanosis with complete repair showed favourable behavioural outcomes compared with controls. Multivariate analyses highlighted the sometimes greater relevance of family processes (eg parenting style, maternal mental health and worry), rather than disease or surgical factors, in predicting especially behavioural outcomes.
The findings (1) suggest a more complex relationship between cyanosis, surgical methods of correction, neuropsychological and behavioural outcomes than previously charted, (2) highlight that family processes may be aetiologically more important than disease and surgical factors, and (3) indicate specific targets for secondary prevention programmes for this at‐risk population.
To identify risk factors for severe childhood malnutrition in a rural South African district with a high HIV/AIDS prevalence.
Bushbuckridge District, Limpopo Province, South Africa.
100 children with severe malnutrition (marasmus, kwashiorkor, and marasmic kwashiorkor) were compared with 200 better nourished (>−2 SD weight-for-age) controls, matched by age and village of residence. Bivariate and multivariate analyses were conducted on a variety of biological and social risk factors.
HIV status was known only for a minority of cases (39%), of whom 87% were HIV positive, while 45% of controls were stunted. In multivariate analysis, risk factors for severe malnutrition included suspicion of HIV in the family (parents or children) (OR 217.7, 95% CI 22.7–2091.3), poor weaning practices (OR 3.0, 95% CI 2.0–4.6), parental death (OR 38.0, 95% CI 3.8–385.3), male sex (OR 2.7, 95% CI 1.2–6.0), and higher birth order (third child or higher) (OR 2.3, 95% CI 1.0–5.1). Protective factors included a diverse food intake (OR 0.53, 95% CI 0.41–0.67) and receipt of a state child support grant (OR 0.44, 95% CI 0.20–0.97). A borderline association existed for family wealth (OR 0.9 per unit, 95% CI 0.83–1.0), father smoking marijuana (OR 3.9, 95% CI 1.1–14.5), and history of a pulmonary tuberculosis contact (OR 3.2, 95% CI 0.9–11.0).
Despite the increasing contribution of HIV to the development of severe malnutrition, traditional risk factors such as poor nutrition, parental disadvantage and illness, poverty, and social inequity remain important contributors to the prevalence of severe malnutrition. Interventions aiming to prevent and reduce severe childhood malnutrition in high HIV prevalence settings need to encompass the various dimensions of the disease: nutritional, economic, and social, and address the prevention and treatment of HIV/AIDS.

To assess endothelial dysfunction and the risk for coronary atherosclerosis in children with irreversible pulmonary hypertension due to congenital heart disease (CHD).
The study included 18 cyanotic patients (the mean age was 12.28 ± 3.26 years) who developed irreversible pulmonary hypertension due to cyanotic and acyanotic CHDs, and 18 control patients (the mean age was 11.78 ± 3.00 years). Study groups were compared for flow-mediated dilatation (FMD), carotid intima media thickness (CIMT) and atherosclerotic risk factors.
Compared to the control group, the mean FMD was significantly reduced in the cyanotic group (5.26 ± 2.42% and 9.48 ± 2.60%, respectively; P-value < 0.001). No significant difference was observed between the groups in CIMT (0.41 ± 0.08 mm and 0.39 ± 0.06 mm, respectively; P-value = 0.299). The levels of total cholesterol, low-density lipoprotein–cholesterol and very low-density lipoprotein–cholesterol were statistically significantly lower compared tothe control group (P-value = 0.001, 0.006 and 0.014, respectively), whereas no statistically significant difference was found in the levels of high-density lipoprotein–cholesterol and triglycerides (P-value = 0.113 and 0.975, respectively).
Systemic endothelial dysfunction in children with irreversible pulmonary hypertension due to CHD was noted but there was no increased risk for atherosclerosis.

The aim of this study was to evaluate the psychopathological influence of congenital heart disease (CHD) in Korean 19-year-old males.
Materials and Methods
The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 211 CHD cases (atrial septal defect, ventricular septal defect, patent ductus arteriosus, or combined CHD) with the KMPI profiles of 300 normal controls. The CHD group was also divided according to whether or not the subjects had undergone open cardiac surgery in order to evaluate the psychopathological effects of an operation among the subjects.
A decreased result on the faking-good response scale and an increased result on the faking-bad response were observed in the CHD group compared to the control (p<0.01). The neurosis scale results, including anxiety, depression and somatization symptoms, were markedly increased in the CHD group compared to the control (p<0.01). The severity level of personality disorder was also increased in the CHD group (p<0.001). Differences in KMPI scale scores were not related to open cardiac surgery history.
In this study, young males with CHD tended to report more abnormal results on the multiphasic personal inventory test in comparison to normal subjects, suggesting that CHD may be related to psychopathology in young males in Korea. Therefore, clinicians are recommended to evaluate the psychopathological traits of patients with CHD.

An important area concerning morbidity among infants with congenital heart defects (CHD) is related to feeding problems. Our objectives were to characterize the evolution of feeding milestones related to transition to per oral feeding among infants with CHD, and to identify associated variables impacting the feeding abilities. Specifically, we differentiated the feeding characteristics in neonates with acyanotic vs cyanotic CHD.
Feeding progress was tracked during the first hospitalization in a retrospective chart review study involving 76 infants (29 acyanotic, 47 cyanotic CHD). The ages at which the following milestones attained were recorded: first feeds, maximum gavage feeds, first nipple feeds and maximum nipple feeds, in addition to the length of hospital stay. Effects of perinatal factors, duration of respiratory support, vasopressor and narcotic use and use of cardiopulmonary bypass on the feeding milestones were also evaluated. ANOVA, t-test, and stepwise linear regression analysis were applied as appropriate. Data stated as mean±s.e.m., or %; P<0.05 was considered significant.
Prenatal and birth characteristics were similar (P = NS) between the neonates with acyanotic and cyanotic CHD. Cyanotic CHD required three times prolonged use of ventilation, narcotics and vasopressor use (all P<0.05, compared to the acyanotic group). In the acyanotic group, prolonged respiratory support correlated linearly with time to attain maximal gavage feeds and nippling (both, R2 = 0.8). In the cyanotic group, delayed initiation of gavage feeds and prolonged respiratory support both correlated linearly with time to attain maximal gavage feeds and nippling (both, R2 = 0.8). Age at first gavage feed correlated with maximum gavage feeds among neonates with cyanotic CHD, and first nipple feed correlated with maximum nipple feeds among all groups (P<0.01). Use of cardiopulmonary bypass in cyanotic CHD delayed the feeding milestones and prolonged the length of stay (both, P<0.05 vs non-bypass group); similar findings were not seen in the acyanotic group.
In contrast to neonates with acyanotic CHD, cyanotic CHD group had significant delays with (a) feeding readiness, (b) successful gastric feeding, (c) oromotor readiness and (d) successful oromotor skills. Co-morbid factors that may directly influence the delay in feeding milestones include the (a) duration of respiratory support and (b) use of cardiopulmonary bypass. Delays in achieving maximum gavage and maximum nippling may suggest foregut dysmotility and oropharyngeal dysphagia.

To assess brain development and brain injury in neonates with cyanotic and acyanotic congenital heart disease (CHD).
The study included 52 term infants with CHD who were divided into two groups: Cyanotic (n=21) and acyanotic (n=31). Fifteen healthy neonates of matched age and sex were enrolled in the study as controls. Three-dimensional proton magnetic resonance spectroscopic imaging and diffusion tensor imaging were used to assess brain development and injury. We calculated the ratio of N-acetylaspartate (NAA) to choline (which increases with maturation), average diffusivity (which decreases with maturation), fractional anisotropy of white matter (which increases with maturation), and the ratio of lactate to choline (which increases with brain injury).
As compared with control neonates, those with CHD had significant decrease in NAA/choline ratio (P<0.001), significant increase in lactate/choline ratio (P<0.0001), significant increase in average diffusivity (P<0.0001), and significant decrease of white matter fractional anisotropy (P<0.001). Neonates with cyanotic CHD had significant less brain development and more brain injury than those with acyanotic CHD (P<0.05).
Newborn infants with cyanotic and acyanotic CHD are at high risk of brain injury and impaired brain maturity.

A cross-sectional study to assess the prevalence of intestinal helminth infections and nutritional status of primary school children was conducted in the Wakiso district in Central Uganda. A total of 432 primary school children aged 6–14 years were randomly selected from 23 schools. Anthropometric measurements of weight, height, MUAC were undertaken and analyzed using AnthroPlus software. Stool samples were examined using a Kato-Katz method. The prevalence of stunting, underweight and moderate acute malnutrition (MAM) was 22.5%, 5.3% and 18.5% respectively. Males had a threefold risk of being underweight (OR 3.2, 95% CI 1.17–9.4, p = 0.011) and 2 fold risk of suffering from MAM (OR 2.1, 95% CI 1.21–3.48, p = 0.004). Children aged 10–14 years had a 2.9 fold risk of stunting (OR 2.9, 95% CI 1.37–6.16, p = 0.002) and 1.9 risk of MAM (OR 1.9, 95% CI 1.07–3.44, p = 0.019). Attending urban slum schools had 1.7 fold risk of stunting (OR 1.7, 95% CI 1.03–2.75, p = 0.027). Rural schools presented a twofold risk of helminth infection (OR 1.95, 95% CI 1.12–3.32, p = 0.012). The prevalence of helminth infections was (10.9%), (3.1%), (1.9%), (0.2%) for hookworm, Trichuria
mansoni and Ascaris
lumbricoides, respectively. The study revealed that 26.6%, 46% and 10.3% of incidences of stunting, underweight and MAM respectively were attributable to helminth infections.

Soil-transmitted helminths (STH) infections, anaemia and malnutrition are major public health problems in school-age children in developing countries. This study was conducted on 289 Orang Asli (aboriginal) schoolchildren in order to assess the current prevalence and predictors of anaemia and malnutrition, as well as the nutritional impacts of STH infections among these children.
A cross-sectional study was combined with a longitudinal follow-up three months after treatment with anthelminthic drugs. Blood samples were collected from the children to measure haemoglobin (Hb) level. Anthropometric and socioeconomic data were also collected and the children were screened for STH.
The baseline findings revealed that the prevalence of anaemia, significant stunting, underweight and wasting among the children were 41.0%, 28.0%, 29.2% and 12.5%, respectively. Overall, the prevalence of trichuriasis, ascariasis and hookworm infections were 84.6%, 47.6% and 3.9%, respectively. Haemoglobin level was significantly lower among the moderate-to-heavy infected children compared to the negative-to-light infected children. Age <10years and moderate-to-heavy ascariasis were the predictors of anaemia. Stunting was associated with gender, age, moderate-to-heavy ascariasis and trichuriasis. Three months post-treatment assessment showed that the moderate-to-heavy infected children gained significant increment in their mean Hb level compared to the negative-to-light infected children (0.44 g/dL compared to 0.08 g/dL). However, no difference was found in the mean increments in growth indices between the groups.
STH infections, anaemia and malnutrition are still prevalent and a matter of public health concern in Orang Asli communities in Malaysia. Sustainable deworming programme at school and community levels among these populations will help to improve their health and nutritional status.

Congenital heart defects (CHD) are among the most common birth defects. There is evidence suggesting that polymorphisms in folate metabolism could alter susceptibility to CHD. The MTHFR 677TT genotype has been associated with the development of structural congenital heart malformations. The objective of this study was to identify common polymorphisms in the MTHFR gene in children with isolated CHD and their mothers. The DNA analysis for the C677T and A1298C mutations was performed. The study group included 27 mothers, 27 children with CHD, and 220 controls. The prevalence of the TT polymorphism was higher in mothers (22%) than in controls (10%). Compound heterozygosity for both polymorphisms was 3.7 times more common in children with CHD than in the newborn controls. Mothers of children with CHD were more likely to be compound heterozygotes. The higher prevalence of C677T polymorphisms in mothers of children with CHD and of compound heterozygosity for both polymorphisms suggests the possible role of folic acid in the prevention of CHD. Due to the relation of this enzyme to folate metabolism, current folate recommendations for women in childbearing age in Puerto Rico to reduce neural tube defects may need to be extended to the prevention of CHD.

In sub-Saharan Africa, preschool children represent the population most vulnerable to malaria and malnutrition. It is widely recognized that malnutrition compromises the immune function, resulting in higher risk of infection. However, very few studies have investigated the relationship between malaria, malnutrition and specific immunity. In the present study, the anti-Plasmodium falciparum IgG antibody (Ab) response was evaluated in children according to the type of malnutrition.
Anthropometric assessment and blood sample collection were carried out during a cross-sectional survey including rural Senegalese preschool children. This cross-sectional survey was conducted in July 2003 at the onset of the rainy season. Malnutrition was defined as stunting (height-for-age <-2 z-scores) or wasting (weight-for-height <-2 z-scores). The analysis was performed on all malnourished children in July (n = 161, either stunted, n = 142 or wasted, n = 19), pair-matched to well-nourished controls. The IgG Ab response to P. falciparum whole extracts (schizont antigens) was assessed by ELISA in sera of the included children.
Both the prevalence of anti-malarial immune responders and specific IgG Ab levels were significantly lower in malnourished children than in controls. Depending on the type of malnutrition, wasted children and stunted children presented a lower specific IgG Ab response than their respective controls, but this difference was significant only in stunted children (P = 0.026). This down-regulation of the specific Ab response seemed to be explained by severely stunted children (HAZ ≤ -2.5) compared to their controls (P = 0.03), while no significant difference was observed in mildly stunted children (-2.5 < HAZ <-2.0). The influence of child malnutrition on the specific anti-P. falciparum Ab response appeared to be independent of the intensity of infection.
Child malnutrition, and particularly stunting, may down-regulate the anti-P. falciparum Ab response, both in terms of prevalence of immune responders and specific IgG Ab levels. This study provides further evidence for the influence of malnutrition on the specific anti-malarial immune response and points to the importance of taking into account child malnutrition in malaria epidemiological studies and vaccine trials.
Objective To assess the implications of adopting the World Health Organization 2006 growth standards in combination with current diagnostic criteria in emergency and non-emergency child feeding programmes.
Design Secondary analysis of data from three standardised nutrition surveys (n=2555) for prevalence of acute malnutrition, using weight for height z score (<−2 and <−3) and percentage of the median (<80% and <70%) cut-offs for moderate and severe acute malnutrition from the National Center for Health Statistics/WHO growth reference (NCHS reference) and the new WHO 2006 growth standards (WHO standards).
Setting Refugee camps in Algeria, Kenya, and Bangladesh.
Population Children aged 6-59 months.
Results Important differences exist in the weight for height cut-offs used for defining acute malnutrition obtained from the WHO standards and NCHS reference data. These vary according to a child's height and according to whether z score or percentage of the median cut-offs are used. If applied and used according to current practice in nutrition programmes, the WHO standards will result in a higher measured prevalence of severe acute malnutrition during surveys but, paradoxically, a decrease in the admission of children to emergency feeding programmes and earlier discharge of recovering patients. The expected impact on case fatality rates of applying the new standards in conjunction with current diagnostic criteria is unknown.
Conclusions A full assessment of the appropriate use of the new WHO standards in the diagnosis of acute malnutrition is urgently needed. This should be completed before the standards are adopted by organisations that run nutrition programmes targeting acute malnutrition.
Early postnatal malnutrition produces delay in growth and developmental processes, and children from a low socioeconomical level where undernutrition is prevalent are shorter than those from higher socioeconomic levels. We examined the effects of severe and early protein energy malnutrition on growth and bone maturation. We studied 40 preschool children who had been admitted to hospital in infancy with protein energy malnutrition and 38 children from the same socioeconomic level, paired for age and sex, who had never been malnourished. Growth measurements were made over a period of 4-6 years, and bone age was determined in a subgroup through wrist roentgenograms. Results showed a correlation between protein energy malnutrition, birth weight of infants, and mother's height and head circumference. The group with protein energy malnutrition showed a significant delay in stature after four years, especially the girls (p less than 0.001). Weight:height ratio was reduced in boys compared with controls but not in girls. Both groups showed a delay in bone maturation, but there were no significant differences between them. We found a positive correlation between bone age and arm fat area in control boys and between bone age and height for age in boys with protein energy malnutrition. The finding that rehabilitated children were shorter than the control group but had similar bone age at follow up suggests that genetic or prenatal factors were important in their later poor growth, and this suggestion is supported by their smaller birth size and the smaller size of their mothers.
To assess and quantify the magnitude of inequalities in under-five child malnutrition, particularly those ascribable to socio-economic status and to consider the policy implications of these findings.
Data on 3765 under-five children were derived from the Living Standards and Development Survey. Household income, proxied by per capita household expenditure, was used as the main indicator of socio-economic status. Socio-economic inequality in malnutrition (stunting, underweight and wasting) was measured using the illness concentration index. The concentration index was calculated for the whole sample, as well as for different population groups, areas of residence (rural, urban and metropolitan) and for each province.
Stunting was found to be the most prevalent form of malnutrition in South Africa. Consistent with expectation, the rate of stunting is observed to be the highest in the Eastern Cape and the Northern Province – provinces with the highest concentration of poverty. There are considerable pro-rich inequalities in the distribution of stunting and underweight. However, wasting does not manifest gradients related to socio-economic position. Among White children, no inequities are observed in all three forms of malnutrition. The highest pro-rich inequalities in stunting and underweight are found among Coloured children and metropolitan areas. There is a tendency for high pro-rich concentration indices in those provinces with relatively lower rates of stunting and underweight (Gauteng and the Western Cape).
There are significant differences in under-five child malnutrition (stunting and underweight) that favour the richest of society. These are unnecessary, avoidable and unjust. It is demonstrated that addressing such socio-economic gradients in ill-health, which perpetuate inequalities in the future adult population requires a sound evidence base. Reliance on global averages alone can be misleading. Thus there is a need for evaluating policies not only in terms of improvements in averages, but also improvements in distribution. Furthermore, addressing problems of stunting and underweight, which are found to be responsive to improvements in household income status, requires initiatives that transcend the medical arena.

Malnutrition is a serious public health problem particularly in developing countries where it is responsible for 54% of under 5s mortality. Anthropometric measurements are key tools for the assessment of nutritional status and diagnosis of malnutrition. Height and weight measurements are not routinely done in most clinics and hospitals in Ghana. Children therefore miss the opportunity for accurate nutritional assessment and detection of malnutrition.
To determine the prevalence of wasting among children <5 years and to document extent of under-diagnosis.
From June to August 2004, children aged >3 months to <5 years attending the outpatient clinic of Komfo Anokye Teaching Hospital were systematically assessed for wasting using weight-for-height standard deviation score (Z-score).
Of 1182 children (mean age 24.9 months), 251 (21.2%) were wasted, 48 (4.1%) of them severely. Only 15 (5.9%) of the 251 children with wasting were so identified by the attending physician.
Malnutrition is widespread yet under-diagnosed. Anthropometric measurements should be promoted in all child health clinics.
