Breast cancer is the most frequently diagnosed malignancy among Chilean women and an increasingly significant public health threat. This study assessed the accuracy of breast cancer risk perception among underserved, Chilean women.
Women aged 50 to 70 years, with no mammogram during the last two years, were randomly selected from a community clinic registry in Santiago, Chile (n=500). Perceived risk was measured using three methods: absolute risk, comparative risk and numerical risk. Risk comprehension was measured by comparing women’s perceived and objective risk estimates. Multivariate logistic regression was used to assess overestimation of perceived risk.
Women at high risk of breast cancer were more likely than average risk women to perceive themselves at high or higher risk, using absolute and comparative risk approaches (p<0.001). The majority of participants (67%) overestimated their breast cancer risk, based on risk comprehension; although, participants achieved higher accuracy with comparative risk (40%) and absolute risk (31.6%) methods. [Age, breast cancer knowledge and Breast Cancer Risk Assessment Tool (BCRAT) 5-year risk were significantly associated (p<0.01) with accuracy of perceived risk].
Chilean women residing in an underserved community may not accurately assess their breast cancer risk, though risk perception and level of accuracy differed between perceived risk measures. Comparative and absolute risk methods may better reflect women’s interpretation and accuracy of risk perception.
Improving our understanding of Chilean women’s perceptions of developing breast cancer may lead to the development of culturally relevant efforts to reduce the breast cancer burden in this population.

In the United States, 5-year breast cancer survival is highest among Asian American women, followed by non-Hispanic white, Hispanic, and African American women. Breast cancer treatment disparities may play a role. We examined racial/ethnic differences in adjuvant hormonal therapy use among women aged 18–64 years, diagnosed with hormone receptor-positive breast cancer, using data collected by the Northern California Breast Cancer Family Registry (NC-BCFR), and explored changes in use over time.
Odds ratios (OR) comparing self-reported ever-use by race/ethnicity (African American, Hispanic, non-Hispanic white vs. Asian American) were estimated using multivariable adjusted logistic regression. Analyses were stratified by recruitment phase (phase I, diagnosed January 1995–September 1998, phase II, diagnosed October 1998–April 2003) and genetic susceptibility, as cases with increased genetic susceptibility were oversampled.
Among 1385 women (731 phase I, 654 phase II), no significant racial/ethnic differences in use were observed among phase I or phase II cases. However, among phase I cases with no susceptibility indicators, African American and non-Hispanic white women were less likely than Asian American women to use hormonal therapy (OR 0.20, 95% confidence interval [CI]0.06–0.60; OR 0.40, CI 0.17–0.94, respectively). No racial/ethnic differences in use were observed among women with 1+ susceptibility indicators from either recruitment phase.
Racial/ethnic differences in adjuvant hormonal therapy use were limited to earlier diagnosis years (phase I) and were attenuated over time. Findings should be confirmed in other populations but indicate that in this population, treatment disparities between African American and Asian American women narrowed over time as adjuvant hormonal treatments became more commonly prescribed.
This study aimed to identify intrapersonal, behavioral, and environmental factors associated with engaging in recommended levels of physical activity among rural Latino middle school youth. Data were from an anonymous survey of 773 Latino youth (51% female) about level of and barriers and motivators to physical activity, risk behaviors, and park use. Logistic regression models identified factors correlated with meeting recommended levels of physical activity (5 days or more 360 min/day). Thirty-four percent of girls and 41% of boys reported meeting this physical activity recommendation. Participation in an organized after school activity (p < .001) and in physical education (PE) classes 5 days a week (p < .001) were strongly associated with meeting recommended physical activity level. Making PE available 5 days a week and creating opportunities for organized after school physical activity programs may increase the number of rural Latino middle school youth who meet recommended physical activity level.
To evaluate long-term change in fruit and vegetable intake following a group randomized trial of worksites.
Medium-sized blue-collar businesses in the Seattle metropolitan area were recruited. Intake was assessed using serial cross-sectional samples of current workforce at 3 time points. The multilevel 18-month intervention involved partnership with the companies. Long-term follow-up was at 4.4 years postbaseline. Statistical analysis used general linear models, adjusting for worksite random effects.
Initially, 45 worksites were randomized, with 29 agreeing to participate in a new study. Fruits and vegetable intake increased, with larger sustained changes in the intervention worksites, resulting in a long-term differential change of 0.25 servings per day, 95% confidence interval (0.09 to 0.40).
Intervention sustained small effects at 4 years, including 2 years with no contact. Although effects were not large, this low-intensity intervention approach could provide an important public health model.

Evidence suggests Latinas residing along the United States-Mexico border face higher breast cancer mortality rates compared to Latinas in the interior of either country. The purpose of this study was to investigate breast cancer knowledge, attitudes, and use of breast cancer preventive screening among U.S. Latina and Mexican women residing along the U.S.-Mexico border.
For this binational cross-sectional study, 265 participants completed an interviewer-administered questionnaire that obtained information on sociodemographic characteristics, knowledge, attitudes, family history, and screening practices. Differences between Mexican (n=128) and U.S. Latina (n=137) participants were assessed by Pearson's chi-square, Fischer's exact test, t tests, and multivariate regression analyses.
U.S. Latinas had significantly increased odds of having ever received a mammogram/breast ultrasound (adjusted odds ratio [OR]=2.95) and clinical breast examination (OR=2.67) compared to Mexican participants. A significantly greater proportion of Mexican women had high knowledge levels (54.8%) compared to U.S. Latinas (45.2%, p<0.05). Age, education, and insurance status were significantly associated with breast cancer screening use.
Despite having higher levels of breast cancer knowledge than U.S. Latinas, Mexican women along the U.S.-Mexico border are not receiving the recommended breast cancer screening procedures. Although U.S. border Latinas had higher breast cancer screening levels than their Mexican counterparts, these levels are lower than those seen among the general U.S. Latina population. Our findings underscore the lack of access to breast cancer prevention screening services and emphasize the need to ensure that existing breast cancer screening programs are effective in reaching women along the U.S.-Mexico border.
Residential proximity to pesticide-treated farmland is an important pesticide exposure pathway.
In-person interviews and biological samples were collected from 100 farmworker and 100 non-farmworker adults and children living in Eastern Washington State. We examined the relationship of residential proximity to farmland to urinary metabolite concentrations of dimethylphosphate (DMTP) and levels of pesticide residues in house dust.
DMTP concentrations were higher in farmworkers than non-farmworkers (71 μg/L vs 6 μg/L) and in farmworker children than non-farmworker children (17 μg/L vs 8 μg/L). Compared to non-farmworker households, farmworker households had higher levels of azinphos-methyl (643 ng/g vs 121 ng/g) and phosmet (153 ng/g vs 50 ng/g). Overall, a 20% reduction in DMTP concentration was observed per mile increase in distance from farmland.
Lower OP metabolite concentrations correlated with increasing distance from farmland.

To examine the relationship between age, race, ethnicity, education, insurance coverage, and income and use of cancer screening services.
We used a population-based sample (N = 1863) from a community randomized intervention study that took place in eastern Washington State.
Pap testing was directly associated with having public health insurance, being 40 and older, and having a high income (>$35,000). Having Medicare coverage was predictive of having had a mammogram or sigmoidoscopy / colonoscopy screening, but not an FOBT.
Our findings may reflect age-dependent factors that influence access to health care.

To explore the association of baseline co-worker social support with follow-up measures of health care use and sickness absence.
Data were obtained on 1,240 employees from 33 worksites, through Promoting Activity and Changes in Eating, a group randomized weight maintenance trial. Co-worker social support, health care utilization, and absenteeism were assessed via a self-reported questionnaire. Generalized Estimating Equations were employed using STATA version 10.
Higher baseline co-worker social support was significantly associated with a greater number of doctors’ visits (p = 0.015). Co-worker social support was unrelated to number of hospitalizations, emergency room visits, or absenteeism.
The relationship between co-worker social support and health care utilization and absenteeism is complex and uncertain. Future studies should measure more specific outcomes, incorporate important mediating variables, and distill how social networks influence these outcomes.
Social support may be associated with improved diet and physical activity—determinants of overweight and obesity. Wellness programs increasingly target worksites. The aim was to evaluate the relationship between worksite social support and dietary behaviors, physical activity, and body mass index (BMI).
Baseline data were obtained on 2,878 employees from 2005 to 2007 from 34 worksites through Promoting Activity and Changes in Eating, a group-randomized weight reduction intervention in Greater Seattle. Worksite social support, diet, physical activity, and BMI were assessed via self-reported questionnaire. Principal components analysis was applied to workgroup questions. To adjust for design effects, random effects models were employed.
No associations were found with worksite social support and BMI, or with many obesogenic behaviors. However, individuals with higher worksite social support had 14.3% higher (95% CI: 5.6%-23.7%) mean physical activity score and 4% higher (95% CI: 1%–7%) mean fruit and vegetable intake compared to individuals with one-unit lower support.
Our findings do not support a conclusive relationship between higher worksite social support and obesogenic behaviors, with the exception of physical activity and fruit and vegetable intake. Future studies are needed to confirm these relationships and evaluate how worksite social support impacts trial outcomes.
Mortality after breast cancer diagnosis is known to vary by race/ethnicity even after adjustment for differences in tumor characteristics. As adjuvant hormonal therapy decreases risk of recurrence and increases overall survival among women with hormone receptor-positive tumors, treatment disparities may play a role. We explored racial/ethnic differences in initiation of adjuvant hormonal therapy, defined as 2 or more prescriptions for tamoxifen or aromatase inhibitor filled within the first year after diagnosis of hormone receptor-positive localized or regional stage breast cancer. The sample included women diagnosed with breast cancer enrolled in Kaiser Permanente Northern California (KPNC).
Odds ratios [OR] and 95% confidence intervals [CI] compared initiation by race/ethnicity (Hispanic, African American, Chinese, Japanese, Filipino, and South Asian vs. non-Hispanic White (NHW)) using logistic regression. Covariates included age and year of diagnosis, area-level socioeconomic status, co-morbidities, tumor stage, histology, grade, breast cancer surgery, radiation and chemotherapy use.
Our sample included 13,753 women aged 20–79 years, diagnosed between 1996 and 2007, and 70% initiated adjuvant hormonal therapy. In multivariable analysis, Hispanic and Chinese women were less likely than NHW women to initiate adjuvant hormonal therapy ([OR]=0.82; [CI] 0.71–0.96 and [OR]=0.78; [CI] 0.63–0.98; respectively).
Within an equal access, insured population, lower levels of initiation of adjuvant hormonal therapy were found for Hispanic and Chinese women. Findings need to be confirmed in other populations and the reasons for under-initiation among these groups need to be explored.

Less than half of youth engage in sufficient physical activity to achieve health benefits. Key environmental factors of park and recreation spaces may influence youth physical activity. We sought to ascertain youth characteristics and behaviors that attract youth to parks with specific amenities and encourage physical activity while at the parks in a rural, predominantly Latino community. We examined the quality of amenities in the 13 parks and recreation spaces that middle school aged youth have access to in their community using the Environmental Assessment of Parks and Recreation Spaces (EAPRS) tool. Middle school students completed surveys in the school classroom (n = 1,102) regarding park use, physical activity, and intrapersonal characteristics (e.g., motivators). We used logistic regression to identify correlates of any park use, use of higher quality field and court parks, and active and sedentary park use. Younger age, participation in an after school activity, and identification of a team as a motivator were positively associated with any park use. Use of higher quality court and field parks was associated with participation in an after school activity and being Latino. The odds of being active in the parks were greater for boys and Latinos. Older age and alcohol use are correlated with being sedentary at the park, while odds of being sedentary at the park were lower for boys and youth who met physical activity guidelines. Organized team activities may encourage active use of higher quality fields and courts parks by Latino youth; thereby, increasing their level of physical activity.

In the US, Hispanic women have a higher incidence of, and mortality from, cervical cancer than non-Hispanic white women. The reason for this disparity may be attributable to both low rates of screening and poor adherence to recommended diagnostic follow-up after an abnormal Pap test. The 'Cervical Cancer Screening and Adherence to Follow-up Among Hispanic Women' study is a collaboration between a research institution and community partners made up of members from community based organizations, the Yakima Valley Farm Workers Clinic and the Breast, Cervical, and Colon Health Program of the Yakima District . The study will assess the efficacy of two culturally-appropriate, tailored educational programs designed to increase cervical cancer screening among Hispanic women, based in the Yakima Valley, Washington, US.
A parallel randomized-controlled trial of 600 Hispanic women aged 21–64, who are non-compliant with Papanicolau (Pap) test screening guidelines. Participants will be randomized using block randomization to (1) a control arm (usual care); (2) a low-intensity information program, consisting of a Spanish-language video that educates women on the importance of cervical cancer screening; or (3) a high-intensity program consisting of the video plus a ‘promotora’ or lay-community health educator-led, home based intervention to encourage cervical cancer screening. Participants who attend cervical cancer screening, and receive a diagnosis of an abnormal Pap test will be assigned to a patient navigator who will provide support and information to promote adherence to follow-up tests, and any necessary surgery or treatment. Primary endpoint: Participants will be tracked via medical record review at community-based clinics, to identify women who have had a Pap test within 7 months of baseline assessment. Medical record reviewers will be blinded to randomization arm. Secondary endpoint: An evaluation of the patient navigator program as a method to improve adherence and reduce time to follow-up among participants who receive an abnormal Pap test result. An additional secondary endpoint is the cost-effectiveness of the two different intensity intervention programs.
This culturally sensitive intervention aims to increase compliance and adherence to cervical screening in a Hispanic population. If effective, such interventions may reduce incidence of cervical cancer.

Breast cancer has the highest incidence of all cancers among women in Chile. In 2005, a national health program progressively introduced free mammography screening for women aged 50 and older; however, three years later the rates of compliance with mammographic screening was only 12% in Santiago, the capital city of Chile. This implementation article combines the findings of two previous studies that applied qualitative and quantitative methods to improve mammography screening in an area of Santiago. Socio-cultural and accessibility factors were identified as barriers and facilitators during the qualitative phase of the study and then applied to the design of a quantitative randomized clinical trial. After six months of intervention, 6% of women in the standard care group, 51.8% in the low intensity intervention group, and 70.1% in the high intensity intervention group had undergone a screening mammogram. This review discusses how the utilization of mixed methods research can contribute to the improvement of the implementation of health policies in local communities.

To evaluate changes in the worksite environment in response to a multilevel intervention over a two year period.
Worksites were recruited in the greater Seattle area, and 34 were randomized to intervention or comparison condition. The intervention was based on the ecological model, with a framework of defined phases of intervention that included worksite wide events implemented in partnership with employee-based advisory boards. The assessment of the worksite environment used a modification of the CHEW. Subscales were developed using baseline data only. The intervention effect on different aspects of the worksite environment was estimated using logistic regression with robust estimating procedures.
Only changes in the physical activity and nutrition information environments were significantly associated with the intervention.
This paper provides one of the first attempts at using environmental assessment in the evaluation of worksite interventions.
Organophosphate pesticides (OPs) are commonly used in the United States, and farm workers are at risk for chronic exposure. Using data from a community randomized trial to interrupt the take-home pathway of pesticide exposure, we examined the association between floor surface type (smooth floor, thin carpet, and thick carpet) and rooms in which dust samples were collected (living room vs. non-living room) and concentrations of azinphos-methyl residues in home environments. We also examined the association between vehicle type (truck, auto, or other) and footwell floor surfaces (carpeted, smooth surface, or no mat) and concentrations of azinphos-methyl in vehicle dust samples. Dust samples were collected from 203 and 179 households and vehicles, respectively. All households had at least one child aged 2–6. Vehicle dust samples were collected from footwells of the vehicle used for commuting to and from work. A total of 183 samples were collected from living rooms, and 20 were collected from other rooms in the home. Forty-two samples were collected from thick carpets, 130 from thin carpets, and 27 from smooth floor surfaces. Thick and thin carpets had a significantly greater dust mass than smooth floor surfaces (6.0 g/m2 for thick carpets, 7.8 g/m2 for thin carpets, and 1.5 g/m2 for smooth surfaces). Of the 179 vehicle samples, 113 were from cars, 34 from trucks, and 32 from other vehicles. Vehicles with no mats had a significantly higher mass of dust (21.3 g) than those with hard mats (9.3 g) but did not differ from vehicles with plush mats (12.0g). Further research is needed to characterize the environment in which children may be exposed to pesticides.

Trained community health promoters (i.e., promotoras) conducted home-based group educational interventions (home health parties) to educate Hispanic women from the Lower Yakima Valley of Washington state about breast cancer and mammography screening.
Women aged 40–79 participating in the parties completed baseline and follow-up surveys 6 months postintervention (n = 70). Changes in general cancer knowledge, breast cancer screening practices, and intentions to be screened among participants from baseline to follow-up were measured using McNemar's test for marginal homogeneity to evaluate the effectiveness of the parties.
The average age of the sample was 50.0 years (standard deviation [SD] 10.0), 84% reported less than an eighth grade education, and 54% were covered by the state's Basic Health Care Plan. Significant changes between baseline and follow-up were observed with respect to (1) believing that risk of cancer could not be reduced (41% vs. 15%, respectively, p = 0.001), (2) ever having a mammogram (83% vs. 91%, p = 0.014), (3) discussing a mammogram with a doctor (37% vs. 67%, p < 0.001), and (4) intending to have a mammogram within the next few months among women who did not report having a mammogram between baseline and follow-up (61% vs. 81%, p = 0.046).
Participation in home-based group educational interventions delivered by promotoras may be associated with improved breast cancer screening practices among Hispanic women.
To describe the relationship between acculturation and human papillomavirus (HPV) infection among diverse US Latinas, a group at high risk for cervical cancer.
Using survey and medical testing data from the 2003–2004 National Health and Nutrition Examination Survey (NHANES), we examined the relationship between acculturation level and HPV infection among diverse Latinas (n=503) and Mexican American women (n=442). Multivariable logistic regression was performed using infection with any type of HPV and with high-risk oncogenic genotypes as outcome variables.
More acculturated Mexican American women were more likely to be infected with high-risk HPV than less acculturated women. In multivariate analyses, Mexican Americans with higher levels of self-rated English language ability (2.48 OR, 95% CI: 1.42–4.33); with birth in the US (2.07 OR, 95% CI: 1.03–4.16); and with US born parents (2.98 OR, 95% CI: 1.45–3.72) were more likely to be infected with high-risk HPV genotypes. Mexican American women with higher levels of acculturation were more likely to test positive for other sexually transmitted infections.
Higher acculturation levels related to more frequent infection with high-risk HPV genotypes and other STIs among US Mexican American women. This association may in part be due to engagement in sexual behaviors.
To evaluate the effectiveness of a community intervention in promoting adoption of behaviors to reduce the take-home pathway of pesticide exposure in farmworker households.
Using two cross-sectional samples of farmworker households in 11 intervention and 12 comparison communities in Washington State, we examined whether differences over time in reported pesticide safety practices varied by community intervention status.
Pesticide safety practices increased in both intervention and comparison communities over time. Changes were significantly greater in intervention communities for removing work shoes before entering the home (p=0.003) and marginally significantly greater for changing out of work clothes within one hour of arriving home (p=0.05).
The intervention was associated with modest effects in certain behaviors among farmworkers. Further research is needed to identify successful strategies for reducing the take-home pathway of pesticide exposure.
A key tenet of community-based participatory research is that communities be involved in all facets of research, from defining the problem to identifying solutions, to assisting in the research, and to participating in the publication of results. In this study, we instituted a small grants program for community participation. A Request for Applications (RFA) was developed and circulated widely throughout the Valley. The RFA sought proposals to address health disparities in cancer education, prevention, and treatment among Hispanics living in the Valley. Funds available were $2,500.00–3,500.00 for 1 year’s worth of work. To help evaluate the progress of the RFA community projects according to the perspectives of the Community Advisory Board (CAB), an open-ended, semi-structured interview was created and administered by a former staff member to CAB members. In 4 years, ten small grants proposed by community members were funded. Funds allocated totaled approximately $25,000. Interviews with CAB members indicated that the RFA program was perceived positively, but there were concerns about sustainability. Our community grants program resulted in the implementation of several novel cancer prevention programs conducted by a variety of community organizations in the Lower Yakima Valley.

We conducted a group-randomized trial to increase smoking cessation and decrease smoking onset and prevalence in 30 colleges and universities in the Pacific Northwest.
Random samples of students, oversampling for freshmen, were drawn from the participating colleges; students completed a questionnaire that included seven major areas of tobacco policies and behavior. Following this baseline, the colleges were randomized to intervention or control. Three interventionists developed Campus Advisory Boards in the 15 intervention colleges and facilitated intervention activities. The freshmen cohort was resurveyed 1 and 2 years after the baseline. Two-years postrandomization, new cross-sectional samples were drawn, and students were surveyed.
At follow-up, we found no significant overall differences between intervention and control schools when examining smoking cessation, prevalence, or onset. There was a significant decrease in prevalence in private independent colleges, a significant increase in cessation among rural schools, and a decrease in smoking onset in urban schools.
Intervention in this college population had mixed results. More work is needed to determine how best to reach this population of smokers.
During February–March 2006, elicitation interviews were conducted with 23 community stakeholders in the Yakima Valley, Washington State to examine concerns about diabetes and to obtain recommendations for how to address concerns among Hispanics in this rural community. Using a snowball approach, stakeholders were identified from organizations providing care/outreach for Hispanics with diabetes. Interviews were guided by a social ecology approach and were conducted as part of a larger parent study using principles of community based participatory research (CBPR). Audio-taped interviews were transcribed, then coded by 3 staff members who identified common themes independently before meeting to reach consensus. Stakeholders represented health care delivery or social service organizations, churches or local radio stations. Diabetes was perceived as an important problem among community members, who often underwent delayed diagnosis of the disease. Lack of disease knowledge, access to appropriate information/services, health insurance, and personal responsibility were perceived as barriers. Stakeholders recommended using exiting organizations and businesses as intervention channels, promoting cultural sensitivity of health professionals/volunteers, creating/distributing appropriate information, and organizing activities to promote awareness/disease-management. Recommendations have informed the design of community interventions to lessen the impact of diabetes in the Yakima Valley.

Cancer survivorship experiences were explored among Hispanic men and women with cancer and family members of cancer survivors, recruited from two rural Washington communities in the Lower Yakima Valley. Five focus groups were conducted from February 2006–October 2007 with 31 women and 10 men. Disbelief, fear, sadness, strength, courage, faith, and hope were common reactions to diagnosis. Concerns about family/children, losing medical coupons, and feelings of depression/isolation were identified as challenges faced after diagnosis. Participants identified smoking and environmental exposures as causes of cancer, but many believed operating on tumors caused cancer to spread. Participants used conventional treatments, but identified herbal/natural remedies as cures. Most participants reported negative experiences with physicians, and believed their community would benefit from language-appropriate information regarding prevention and treatment. The importance of linking survivors through support groups was emphasized and information elicited from sessions has been used to organize survivor support groups in these two communities.

Background. Breast cancer is the leading cause of cancer among women in Chile and in many Latin American countries. Breast cancer screening is an effective strategy to reduce mortality, but it has a very low compliance among Chilean women.
Objective. To understand barriers and facilitators for breast cancer screening in a group of Chilean women aged 50–70.
Methods. Following the Predisposing, Enabling and Reinforcing (PRECEDE) framework, seven focus groups (N = 48 women) were conducted with women that have had diverse experiences with breast cancer and screening practices. Information was collected using field notes and audio and video recording. Following the grounded theory model, a sequential process of open, axial and selective coding was used for the information analysis. Atlas ti 5.5 software was used for coding and segmenting the data obtained from the interviews.
Results. The presence of symptoms and/or the finding of lumps through breast self-examination (BSE) were the main predisposing factors for getting a mammogram. Secrecy, embarrassment and fatalism about breast cancer were significant cultural factors that influenced the decision to seek mammogram screening. Confidence in medical staff and dignity in the treatment at the clinic were important enabling factors. The main reinforcing factors for getting the test were a sense of fulfilment by doing something good for themselves and getting timely information about the results.
Conclusions. Primary health care providers should use culturally appropriate strategies to better inform women about the importance of mammography screening and the limitations of BSE for preventing advanced breast cancer.

We used community-based ethnography and public health risk assessment to assess beliefs about pesticide exposure risks among farmworkers in the Lower Yakima Valley of Washington State.
We used unstructured and semistructured interviews, work-site observation, and detailed field notes to gather data on pesticide exposure risks from 99 farmworkers.
Farmworkers’ pesticide-relevant beliefs and attitudes could be grouped into 5 major themes: (1) dry pesticides are often perceived as a virtually harmless powder, (2) farmworkers who identify themselves as allergic to pesticides are more acutely affected by exposure, (3) the effect of pesticide exposure is more severe for those perceived as physically weak, (4) protective equipment is used selectively in response to financial pressure to work rapidly, and (5) some farmworkers delay decontamination until they find water deemed an appropriate temperature for handwashing.
We elucidated farmworkers’ pesticide-relevant beliefs regarding perceived danger and susceptibility to pesticides, the need to put safety second to financial considerations, and reasons for delaying decontamination. Researchers and policymakers should incorporate these data in study designs and legislation concerned with farmworker exposure to pesticides.
