Population Attributable Fraction of Hypertension Associated with Obesity in Iran

Introduction: prevalence of obesity has been increased in iran over the recent decades. little is known about fraction of hypertension attributable to obesity in iran. this study aimed to determine the population attributable fraction (paf) of hypertension due to obesity across different provinces of iran. materials and methods: data on prevalence of hypertension were extracted from iranian ministry of health non- communicable disease risk factor infobase. measure of association between hypertension and obesity was extracted from tehran lipid and glucose study, for men and women separately. the extracted relative risks were used to calculate paf of hypertension associated with obesity after age standardization of the reported prevalence of obesity across different provinces of iran. results: in this study, paf of hypertension associated with obesity observed in females; 25.6 (95% ci:18.9-30.1) was more than that of males; 24.6 (95% ci: 18.1-29.2), in males across different provinces, north-khorasan had the highest paf of hypertension due to obesity 24.6 (95% ci: 18.1-29.2), followed by qom; 22.6 (95% ci: 16.5-26.7), and hormozgan; 22.5 (95% ci: 16.5-26.6). in females, north-khorasan province had the highest paf; 25.6 (95% ci: 18.9-30.1) followed by semnan 22.3 (95% ci: 16.5-26.3), hormozgan 20.9 (95% ci: 15.5-24.6), as well as qom 20.7 (95% ci: 15.5-24.6). conclusion: prevalence of hypertension is relatively high in provinces of iran and a sizable share of it is associated with obesity. it is recommended that health promotion programs focus on obesity in these provinces.
