The main aim of this study is to determine the central obesity trends during the period from 2006 to 2010 among 15-65 years old people in Northern Iran.
This was a population-based cross-sectional study conducted on 6466 subjects who had been chosen by a multi stage cluster random sampling within five steps. The subjects were randomly chosen from 325 clusters and each cluster included 20 cases. Central obesity was defined as waist circumference ³102 cm and ³88 cm in men and women, respectively.
Compared to 2010, the mean waist circumference in 2006 changed from 87.2 cm to 88.1 cm in men (p=0.237), and from 90.3 cm to 88.6 cm in women (p=0.045). The comparison between 2006 and 2010 revealed that the prevalence of central obesity slightly decreased, 6.8% and 2.4% in urban women and men, respectively. Generally, the mean of waist circumference significantly decreased in urban women (by 0.069 cm in each year; p=0.020); however, the decrease of waist circumference in urban men was not significant (0.006 cm decrease each year; p=0.915).
The prevalence of central obesity declined among both males and females in the urban area; however, there was an attenuated increasing trend in the rural area. The disparity of trends between the two regions should be considered for further study.
本研究的主要目的是确定2006年至2010年期间伊朗北部15至65岁人群的中心性肥胖趋势。
这是一项基于人群的横断面研究，对6466名受试者进行了研究，这些受试者是通过五步多阶段整群随机抽样选择的。受试者从325个群组中随机选取，每个群组包括20个病例。中心性肥胖定义为男性腰围≥102厘米，女性腰围≥88厘米。
与2010年相比，2006年男性的平均腰围从87.2厘米变为88.1厘米（p = 0.237），女性从90.3厘米变为88.6厘米（p = 0.045）。2006年与2010年的比较显示，中心性肥胖的患病率略有下降，城市女性和男性分别为6.8%和2.4%。总体而言，城市女性的腰围平均值显著下降（每年下降0.069厘米；p = 0.020）；然而，城市男性腰围的下降不显著（每年下降0.006厘米；p = 0.915）。
城市地区男性和女性的中心性肥胖患病率均有所下降；然而，农村地区存在减弱的上升趋势。两个地区趋势的差异应在进一步研究中予以考虑。
