Recent estimates show the prevalence of obesity to be increasing at alarming rates. This study was conducted to examine trends of prevalence in overweight, obesity and central fat accumulation among Tehranian adults between 1998 and 2002.
Height and weight of 2,102 adults, aged 20-80 years, participants of the Tehran Lipid and Glucose Study, were measured in 1998-1999 and remeasured in 2001-2002, after 3 years. Criteria used to state prevalence of overweight and obesity were body mass index (BMI) 25-29.9 and > or =30, respectively. Central fat accumulation was defined as waist-hip ratio (WHR) > or =0.8 in women and > or =0.9 in men. Individuals were divided into 10-year groups and the prevalence of obesity was compared according to sex and age.
In 1998-1999 and 2001-2002, mean BMI was 26.1 +/- 4.1 and 26.7 +/- 4.1 kg/m(2) in men (p < 0.001) and 27.8 +/- 4.9 and 28.7 +/- 5.9 kg/m(2) in women (p < 0.001), respectively. Mean WHR in women was 0.84 +/- 0.08 in 1998-1999 and 0.88 +/- 0.08 in 2001-2002 (p < 0.001). The prevalence of overweight in men was 42.5 and 46% and 40 and 39.5% in women in the two mentioned periods. The prevalence of obesity was 32.7 and 40.3% in men and 16.5 and 20.8% in women in 1998-1999 and 2001-2002 respectively. In both sexes the fastest increasing trends in obesity and central fat accumulation were seen in the 30- to 40- and 20- to 30-year-old age groups. Comparison of the 50th percentile of BMI in all age groups showed a significant increase in 2001-2002 as compared to 1998-1999 (p < 0.01).
The findings demonstrate significant rises in the prevalence of both total and central fat accumulation, calling for urgent action to educate people in lifestyle modifications.
近期估计显示肥胖患病率正以惊人的速度上升。本研究旨在调查1998年至2002年德黑兰成年人中超重、肥胖及中心性脂肪堆积患病率的变化趋势。
对德黑兰血脂与血糖研究的2102名年龄在20 - 80岁的成年人，于1998 - 1999年测量身高和体重，并在3年后的2001 - 2002年再次测量。超重和肥胖患病率的判定标准分别为体重指数（BMI）25 - 29.9及≥30。中心性脂肪堆积定义为女性腰臀比（WHR）≥0.8，男性≥0.9。将个体分为10岁年龄组，并根据性别和年龄比较肥胖患病率。
在1998 - 1999年和2001 - 2002年，男性的平均BMI分别为26.1±4.1和26.7±4.1kg/m²（p<0.001），女性分别为27.8±4.9和28.7±5.9kg/m²（p<0.001）。1998 - 1999年女性平均WHR为0.84±0.08，2001 - 2002年为0.88±0.08（p<0.001）。上述两个时期男性超重患病率分别为42.5%和46%，女性分别为40%和39.5%。1998 - 1999年和2001 - 2002年男性肥胖患病率分别为32.7%和40.3%，女性分别为16.5%和20.8%。在男女两性中，肥胖和中心性脂肪堆积增长最快的趋势出现在30 - 40岁和20 - 30岁年龄组。所有年龄组BMI第50百分位数的比较显示，2001 - 2002年相较于1998 - 1999年有显著增加（p<0.01）。
研究结果表明总体和中心性脂肪堆积的患病率均显著上升，呼吁采取紧急行动对人们进行生活方式改变方面的教育。
