['We examined associations between television viewing and prevalence of the metabolic syndrome among a representative sample of Caribbean-origin Hispanic elders living in Massachusetts.', 'We conducted a cross-sectional analysis of 350 Puerto Rican and 105 Dominican elders (> or = 60 years). Information on television viewing hours was collected by a questionnaire. The metabolic syndrome was defined by using the definition from the National Cholesterol Education Program.', 'Prevalences for the metabolic syndrome were 50.1 and 56.9% among Puerto Ricans and Dominicans, respectively. Of the subjects, 82.6% had high blood pressure and 61.4% had high fasting glucose. Prevalence of the syndrome was significantly associated with television viewing. Each additional hour of television viewing was associated with a 19% greater likelihood of having the metabolic syndrome (odds ratio [OR] 1.19, 95% CI 1.1-1.3, P for trend 0.002), after adjusting for age, sex, ethnicity, BMI, education, alcohol use, smoking, household arrangement, physical activity, intake of energy and fat, and activities-of-daily-living score. We did not observe significant interactions of television viewing with sex, smoking status, alcohol use, or BMI (P for interaction > 0.15 for all) in relation to presence of the metabolic syndrome.'] Is television viewing associated with prevalence of metabolic syndrome in Hispanic elders?
