This cross-sectional study examined whether length of time in the U.S., language use, and birthplace (proxy measures of acculturation) were associated with body mass index (BMI) and obesity in a sample of 174 low-income Puerto Rican women from Hartford, Connecticut. The mean BMI for the total sample (N = 174) was 27.39 (S.D. = 5.07), and nearly 34% of the sample was considered obese (BMI > or = 30). There was a statistically significant increase in BMI with length of time in the U.S. (P = 0.012) and these differences were even greater among women born in Puerto Rico (P = 0.003). Moreover, obesity prevalence was highest among women who had been in the U.S. for 10 years or more (40%), as compared to those who had been in the U.S. less than 1 year (29%; P = 0.045). There were no statistically significant associations between language and BMI for the total sample. However, among bilingual speakers born in Puerto Rico, there were significant differences in BMI according to their level of English fluency. Those who spoke fluent or very good English had a significantly higher BMI (mean = 29.72; SD = 4.12) than women whose English was good to not-so-good (mean = 26.8; SD = 5.24; P = 0.016). The findings from this study point to the need for more research on the acculturation process and obesity, in order to design culturally tailored obesity prevention programs.

The purpose of this case-control study was to identify predictors of obesity among Puerto Rican children from Hartford, CT. The study included 53 prepubertal children, 31 girls and 22 boys, between 7 and 10 y of age. Children were classified as obese [n = 29, body mass index (BMI) >/= 85th percentile] or controls (n = 24, BMI < 85th percentile). Multivariate logistic regression analyses indicated that frequency of fruit juice consumption [odds ratio (OR), 95% confidence interval (CI); 4.02, 1.48-10.95], hours of daily TV viewing (1.86, 1.02-3.42), maternal BMI (1.39, 1.10-1.77) and lower dairy product intake (0.41, 0.19-0.93) were associated with obesity. Television viewing was correlated (P < 0.05) with lower physical activity in girls, and with higher snacking frequency and sweets consumption in boys. Obese children were more likely than controls to have higher systolic and diastolic blood pressures and to have experienced more ear infections and diarrhea during the previous year. Results provide evidence of the multifactorial nature of childhood obesity in this community.

Recently a few vocal health experts have suggested that some of the billions of dollars currently used to prevent and treat HIV and AIDS be reallocated to address more basic problems such as malnutrition, tuberculosis, malaria, and enteric and diarrheal disease caused by lack of access to clean water. While not universally agreed upon, this reassessment of policy priorities acknowledges that there are multiple other health problems that deserve renewed attention from the international community. It also highlights the fact that the impacts of the HIV pandemic are exacerbated by widespread poverty, food insecurity and malnutrition, and gender inequality. Nowhere is this more evident than in sub-Saharan Africa, where multiple epidemics conflate and seriously compromise the survival of individuals and communities. Given the widespread occurrence of famine in sub-Saharan Africa, issues of food and economic security become of paramount importance in efforts to address the region's HIV epidemics. This paper examines the historical, political-economic, and cultural dimensions of the HIV epidemic in the context of the growing problem of food and economic insecurity. Furthermore, using theoretical frameworks that emphasize the dynamic interrelation between HIV/AIDS and food insecurity, we present suggestions for combining traditional HIV-prevention strategies with food production and nutritioneducation programming. In light of the complex interactions between HIV/AIDS and food insecurity and the lack of accessible treatment modalities, such programming could potentially reduce the risk for transmission of HIV through behavioural changes and improved nutritional and immune status, and increase the life expectancy of people living with HIV or AIDS.
