Elevated Levels of Organochlorine Pesticides in South Asian Immigrants Are Associated With an Increased Risk of Diabetes.

ABSTRACT:

Objective

Rates of diabetes mellitus are higher in South Asians than in other populations and persist after migration. One unexplored cause may be higher exposure to persistent organic pollutants associated with diabetes in other populations. We compared organochlorine (OC) pesticide concentrations in South Asian immigrants and European whites to determine whether the disease was positively associated with OC pesticides in South Asians.

Research design and methods

South Asians of Tamil or Telugu descent (n = 120) and European whites (n = 72) were recruited into the London Life Sciences Population Study cohort. Blood samples as well as biometric, clinical, and survey data were collected. Plasma levels of p,p'-dichlorodiphenyldichloroethylene (DDE), p,p'- dichlorodiphenyltrichloroethane, ?-hexachlorohexane (HCH), and polychlorinated biphenyl-118 were analyzed by gas chromatography-mass spectrometry. South Asian cases and controls were categorized by binary exposure (above vs below the 50th percentile) to perform logistic regression.

Results

Tamils had approximately threefold to ninefold higher levels of OC pesticides, and Telugus had ninefold to 30-fold higher levels compared with European whites. The odds of exposure to p,p'-DDE above the 50th percentile was significantly greater in South Asian diabetes cases than in controls (OR: 7.00; 95% CI: 2.22, 22.06). The odds of exposure to ?-HCH above the 50th percentile was significantly greater in the Tamil cases than in controls (OR: 9.35; 95% CI: 2.43, 35.97).

Conclusions

South Asian immigrants have a higher body burden of OC pesticides than European whites. Diabetes mellitus is associated with higher p,p'-DDE and ?-HCH concentrations in this population. Additional longitudinal studies of South Asian populations should be performed.

Project description:BACKGROUND:This paper describes the design and methods of a multi-phase study to reduce early childhood caries and obesity in vulnerable South Asian (SA) immigrants in the United States. Early childhood caries and obesity are the most common diseases of early childhood. Risk factors for both diseases are rooted in early childhood feeding practices such as bottle feeding and intake of sweets and sweetened beverages. The Common Health/Risk Factor Approach to addressing oral health is widely promoted by the WHO and other policy makers. This approach recognizes links between oral health and other diseases of modernity. Our CHALO! ("Child Health Action to Lower Obesity and Oral health risk"--from a Hindi word meaning "Let's go!") study targets SA families at high risk for early childhood caries and obesity. CHALO! addresses common risk factors associated with these two common diseases of childhood. METHODS:This two part project includes a randomized controlled trial, and a Knowledge Translation campaign. A randomized controlled trial will enroll n = 360 families from pediatric practices serving South Asians in the New York metro area. The intervention group will receive home visits by SA community health workers at 6, 8, 10, 12, 14, and 16 months of age. Controls will receive culturally tailored educational material. Primary outcomes-- cariogenic and obesogenic feeding practices at 6, 12, and 18 months-- will be assessed with the MySmileBuddy iPad based tool. Secondary outcomes include: oral hygiene practices, anthropometrics, and caries incidence at 18 months. A public education campaign will focus on both families and health care providers. DISCUSSION:There are few Common Health/Risk Factor Approach published studies on obesity and oral health risk in children, despite health morbidity and costs associated with both conditions. CHALO! comprises a multi-level interventions designed to promote culturally competent, sustainable change. TRIAL REGISTRATION:ClinicalTrials.gov NCT03077425 .
