Background and Objectives

The prevalence of both obesity and type 2 diabetes has increased in recent years. In this study, we aimed to evaluate the prevalence of obesity and type 2 diabetes and to investigate the contribution of obesity to the increased prevalence of type 2 diabetes in urban and rural Iranian communities.

Methods

This study was based on four surveys from the Surveillance Survey of Risk Factors of Non-communicable Diseases (SuRFNCD), conducted in 2005, 2007, 2011, and 2016. The contribution of general and abdominal obesity to the prevalence of type 2 diabetes was determined based on the population attributable fraction (PAF).

Results

The mean (95% CI) age and body mass index (BMI) of the participants were 36.9 years (36.8–36.9) and 25.9 kg/m² (25.9–26.0), respectively. The increasing rates of general obesity and diabetes were 37% and 80% among urban residents and 63% and 68% among rural residents, respectively. The PAF of general obesity and abdominal obesity to the prevalence of type 2 diabetes was 20.2% and 33.4% in urban residents and 11.8% and 21.0% in rural residents, respectively.

Conclusion

The prevalence of both obesity and type 2 diabetes has increased over the past 12 years. Besides, general and abdominal obesity played a substantial role in increasing the prevalence of type 2 diabetes in both urban and rural populations.

近十年来，肥胖对伊朗城乡成年人 2 型糖尿病患病率增加的贡献

背景和目标

近年来，肥胖和 2 型糖尿病的患病率都有所增加。在这项研究中，我们旨在评估肥胖和 2 型糖尿病的患病率，并调查肥胖对伊朗城市和农村社区 2 型糖尿病患病率增加的贡献。

方法

本研究基于 2005 年、2007 年、2011 年和 2016 年进行的非传染性疾病危险因素监测调查 (SuRFNCD) 的四项调查。确定了一般肥胖和腹部肥胖对 2 型糖尿病患病率的贡献基于人口归因分数（PAF）。

结果

参与者的平均 (95% CI) 年龄和体重指数 (BMI) 分别为 36.9 岁 (36.8-36.9) 和 25.9 kg/m ² (25.9-26.0)。城市居民一般肥胖和糖尿病的增加率分别为37%和80%，农村居民分别为63%和68%。一般肥胖和腹部肥胖对2型糖尿病患病率的PAF在城市居民中分别为20.2%和33.4%，在农村居民中分别为11.8%和21.0%。

结论

在过去的 12 年中，肥胖症和 2 型糖尿病的患病率都有所增加。此外，一般肥胖和腹部肥胖在增加城市和农村人口中 2 型糖尿病的患病率方面发挥了重要作用。
