1.  Blood pressure centiles for Great Britain 
Archives of Disease in Childhood  2006;92(4):298-303.
Objective
To produce representative cross‐sectional blood pressure reference centiles for children and young people living in Great Britain.
Design
Analysis of blood pressure data from seven nationally representative surveys: Health Surveys for England 1995–8, Scottish Health Surveys 1995 and 1998, and National Diet & Nutrition Survey 1997.
Methods
Blood pressure was measured using the Dinamap 8100 with the same protocol throughout. Weight and height were also measured. Data for 11 364 males and 11 537 females aged 4–23 years were included in the analysis, after excluding 0.3% missing or outlying data. Centiles were derived for systolic, diastolic, mean arterial and pulse pressure using the latent moderated structural (LMS) equations method.
Results
Blood pressure in the two sexes was similar in childhood, rising progressively with age and more rapidly during puberty. Systolic pressure rose faster and was appreciably higher in adult men than in adult women. After adjustment for age, blood pressure was related more to weight than height, the effect being stronger for systolic blood pressure. Pulse pressure peaked at 18 years in males and 16 years in females.
Conclusions
These centiles increase our knowledge of blood pressure norms in contemporary British children and young people. High blood pressure for age should be defined as blood pressure above the 98th centile, and high‐normal blood pressure for age as blood pressure between the 91st and 98th centiles. The centiles identify children and young people with increased blood pressure, and will be of benefit to both clinical practice and research.

2.  A low cost, colour coded, hand held spring scale accurately categorises birth weight in low resource settings 
Archives of Disease in Childhood  2006;91(5):410-413.
Aims
To determine the accuracy of a low cost, spring calibrated, hand held scale in classifying newborns into three weight categories (⩾2500 g, 2000–2499 g, <2000 g).
Methods
The test device was compared to a gold standard digital baby scale with precision to 2 g. In Sarlahi district, Nepal, 1890 newborns were eligible for the study. Measurements were collected for both the test device and the digital scale from 1820 (96.3%) newborns.
Results
The overall low birth weight (LBW) prevalence rate for the gold standard digital scale was 28.1% (511/1820). Sensitivity (93.7%) and specificity (97.6%) of the test device was high compared to LBW classifications based on digital weight measurements. Classification of infants into the <2000 g category was 5.0% and 4.7% for the gold standard and test device, respectively. Sensitivity and specificity of the test device in identifying infants <2000 g was 87.8% and 99.6%, respectively. Positive predictive values were high (>91%) for both weight categories
Conclusions
This low cost, simple‐to‐use device classified infants into weight categories with a high degree of consistency and accuracy that exceeds that of surrogate measures. This new device is useful for identifying and targeting life saving interventions for LBW, high risk infants in settings where infants are born in the home and conventional weighing scales are unavailable.

Classification of infants into the ,2000 g category was 5.0% and 4.7% for the gold standard and test device, respectively. Sensitivity and specificity of the test device in identifying infants ,2000 g was 87.8% and 99.6%, respectively. Positive predictive values were high (.91%) for both weight categories
