تاثير چاقي، چاقي شكمي و اثر توام هر دو عامل در افزايش فشارخون مردان استان مازندران (مطالعه كسر منتسب به جمعيت): گزارش كوتاه

The effect of obesity, abdominal obesity and joint effect of them on high blood pressure in men of Mazandaran Province, Iran (population attributable fraction study): brief report

زمینه و هدف: چاقی و چاقی شكمی از جمله عوامل خطر فشارخون می‌باشند، مطالعه حاضر با هدف تعیین سر منتسب به جمعیت فشارخون در اثر چاقی و چاقی شكمی و اثر توام هر دو در مردان استان مازندران انجام شد. روش بررسی: این مطالعه یك مطالعه اپیدمیولوژیك بود كه از داده‌های نظام مراقبت بیماری‌های غیرواگیر كه در اردیبهشت ماه سال 1388 به‌دست آمده استفاده شده و اندازه خطر نیز از مطالعه قند و لیپید به‌دست آمده سپس خطر منتسب به جمعیت بر اساس فرمول كسر منتسب محاسبه شد. یافته‌ها: بر اساس نتایج به‌دست آمده كسر منتسب به جمعیت فشارخون در اثر چاقی (2/17-10/7 :95%CI) 5/14، چاقی شكمی (3/11-04/2 :95%CI)4/7 و اثر مشترك هر دو عامل (6/25-7/9 :95%CI) 6/22 به‌دست آمد. نتیجه‌گیری: با توجه به شیوع بالای فشارخون و چاقی در مردان استان مازندران لازم است تا در زمینه پیشگیری از شیوع این بیماری‌ها در مردان استان مازندران اقدامات موثری صورت گیرد.

Background: Hypertension is one of the most important chronic illness worldwide and one the major risk factors for cardiovascular diseases. Obesity and abdominal obesity are risk factors for high blood pressure. Population attributable fraction (PAF) answers the question of how much of the disease burden in a certain population may be reduced if a risk factor like obesity is removed from the population. It implies that reducing prevalence of obesity as a risk factor of hypertension, may reduce the burden of hypertension and its consequences. The aim of this study was to determine the population attributable fraction of hypertension associated with obesity, abdominal obesity and joint effect of them in the men of Mazandaran Province, North of Iran. Methods: In this epidemiological study, the data of non-communicable disease surveillance system in 2009 has been achieved. Then measure of association between obesity and hypertension (Odds Ratio) was extracted from Tehran Lipid and Glucose Study (TLGS). After standardizing the data, the population attributable risk for men based on the above formula (Levinʹs attributable fraction formula) has been calculated. Results: In our study based on population attributable fraction, results in blood pressure caused by obesity were 14.5 (CI 95%: 10.7-17.2), the effect of abdominal obesity was 7.4 (CI 95%: 2.04-11.3) and deductions attributable joint effect both obesity and abdominal obesity was 22.6 (CI 95%: 9.7-25.6) respectively. Conclusion: Given the high prevalence of hypertension and obesity in Mazandaran men and the impact of obesity on blood pressure is necessary to prevent the spread of the disease. It is recommended that health promotion programs focus on men with high blood pressure due to obesity could be performed.
