The aim of this study was to determine the prevalence of overweight and obesity and their associated factors in the middle-aged population of Shahroud, North of Iran.
In a population-based cross-sectional study with random cluster sampling, 300 clusters of Shahroud (north of Iran) were randomly selected from the 40-64 yr old population of the city, during 2009 and 2010. Upon enrollment, participants were weighed on digital scales and their heights were measured under standard conditions. Overweight and obesity were defined as a body mass index (BMI) of 25-29.9 kg/m and a BMI ≥30 kg/m, respectively.
Of the 6311 selected people, 5190 people (82.2%) participated in the study. Their mean age was 50.9±6.2 yr, and 2977 of them were women (57.4%). Age and gender standardized mean BMI in the study population were 28.1 kg/m (95% CI: 27.9-28.2). Age and gender-standardized prevalence of BMI≥25 was 74.4% (95% CI: 73.0-75.8); 43.4% (95% CI 44.8-42.0) were overweight and 31.0% (95% CI 32.5-29.6) were obese. Overweight, Obesity and a BMI ≥25 prevalence's were significantly higher in women (<0.001). In the multiple logistic regression models, female gender and higher economic status were significantly correlated with BMI≥25. In addition, people over the age of 54 yr were more likely to have BMI≥25 than those in the 40-44 yr age range (<0.001).
The prevalence of overweight and obesity in the present study, especially in women, was higher than that reported from previous studies in Iran. Considering prevention, programs for overweight and obesity-related are suggested as a priority for the health system in this population.
本研究旨在确定伊朗北部沙赫鲁德中年人群中超重和肥胖的患病率及其相关因素。
在一项采用随机整群抽样的基于人群的横断面研究中，于2009年至2010年期间从该市40 - 64岁人群中随机选取了300个沙赫鲁德（伊朗北部）的整群。入选时，使用数字秤对参与者进行称重，并在标准条件下测量其身高。超重和肥胖分别定义为体重指数（BMI）为25 - 29.9kg/m²和BMI≥30kg/m²。
在6311名被选中的人中，5190人（82.2%）参与了研究。他们的平均年龄为50.9±6.2岁，其中2977人为女性（57.4%）。研究人群中年龄和性别标准化的平均BMI为28.1kg/m²（95%CI：27.9 - 28.2）。年龄和性别标准化的BMI≥25的患病率为74.4%（95%CI：73.0 - 75.8）；超重者占43.4%（95%CI 44.8 - 42.0），肥胖者占31.0%（95%CI 32.5 - 29.6）。女性的超重、肥胖及BMI≥25的患病率显著更高（<0.001）。在多因素逻辑回归模型中，女性性别和较高的经济地位与BMI≥25显著相关。此外，54岁以上的人比40 - 44岁年龄组的人更有可能BMI≥25（<0.001）。
本研究中超重和肥胖的患病率，尤其是女性中的患病率，高于伊朗先前研究报告的患病率。考虑到预防，建议将与超重和肥胖相关的项目作为该人群卫生系统的优先事项。
