To determine the prevalence of arterial hypertension and cardiovascular risk factors (CRF) in a rural population exposed to arsenic (As) in drinking water in the province of Tucumán, Argentina. A total of 352 adult inhabitants participated. Consumption of arsenic in drinking water was measured. Blood pressure, smoking, risk and harmful alcohol consumption, salt intake, physical activity, body mass index, glycemia and dyslipidemia were evaluated. Cardiovascular risk was calculated using the Framingham score. The population was divided into Exposed Group (EG) n=90 and Non-Exposed Group (NEG) n=262. The prevalence of hypertension was 48.9 and 51.1% in each group, respectively; for smoking it was 31.1 and 39.7%; for risky alcohol consumption, 22.2 and 17.9%; for harmful alcohol consumption, 36.6 and 36.6%; for salt intake, 100 and 100%; for physical activity, 16.7 and 18.7%; for being overweight, 43.3 and 43.9%; for obesity, 25.5 and 25.6%; for diabetes, 24.4 and 32.8%; and for dyslipidemia, 58.9 and 66.4%. The scores for low, moderate, or high-risk were 50; 21.1; and 28.9% in the EG, and 54.6; 19.1 and 26.3% in the NEG, respectively. Exposure to As does not affect the prevalence of CRFs. We identified a rural population in a vulnerable condition with high CRFs. The National Risk Factor Survey does not reflect what happens in rural areas. The Framingham scale is consistent with the found CRFs. The implementation of health promotion policies is required to improve the prognos
Abstract
To determine the prevalence of arterial hypertension and cardiovascular risk factors (CRF) in a rural population exposed to arsenic (As) in drinking water in the province of Tucumán, Argentina. A total of 352 adult inhabitants participated. Consumption of arsenic in drinking water was measured. Blood pressure, smoking, risk and harmful alcohol consumption, salt intake, physical activity, body mass index, glycemia and dyslipidemia were evaluated. Cardiovascular risk was calculated using the Framingham score. The population was divided into Exposed Group (EG) n=90 and Non-Exposed Group (NEG) n=262. The prevalence of hypertension was 48.9 and 51.1% in each group, respectively; for smoking it was 31.1 and 39.7%; for risky alcohol consumption, 22.2 and 17.9%; for harmful alcohol consumption, 36.6 and 36.6%; for salt intake, 100 and 100%; for physical activity, 16.7 and 18.7%; for being overweight, 43.3 and 43.9%; for obesity, 25.5 and 25.6%; for diabetes, 24.4 and 32.8%; and for dyslipidemia, 58.9 and 66.4%. The scores for low, moderate, or high-risk were 50; 21.1; and 28.9% in the EG, and 54.6; 19.1 and 26.3% in the NEG, respectively. Exposure to As does not affect the prevalence of CRFs. We identified a rural population in a vulnerable condition with high CRFs. The National Risk Factor Survey does not reflect what happens in rural areas. The Framingham scale is consistent with the found CRFs. The implementation of health promotion policies is required to improve the prognosis of suffering cardiovascular events in the short and medium term.
