The purpose of this study was to compare temporal changes in BMI (kg/m2) and obesity among adult (aged > or = 18 years) Kuwaiti men using 2 independent cross-sectional samples of 896 and 1,730 subjects, studied for nutritional assessment and for prevalence of obesity in 1980-81 and 1993-94, respectively. The samples were drawn from primary health care (PHC) clinics and measured for body mass index (BMI), and obesity, defined as BMI > 25 (grade 1) and > 30 (grade 2) kg/m2. The results of the study showed that mean BMI (kg/m2) and prevalence of grade 1 and 2 obesity (BMI > 25 and > 30 kg/m2) increased by 10 (2.5 kg/m2), 20.6 and 15.4%, respectively. After controlling for sociodemographic differences between the two study periods, mean BMI was 2 kg/m2 higher in 1993-94 than in 1980-81 and prevalence of obesity (BMI > 25 and > 30 kg/m2) also increased between the two periods (OR = 2.1, 95% CI 1.7-2.7 and OR = 1.9, 95% CI 1.5-2.4, respectively). In conclusion, BMI and prevalence of obesity increased among Kuwaiti men between 1980-81 and 1993-94, due to modernization, affluence and the concomitant changes to sedentary lifestyles. The rates of temporal changes in BMI and in prevalence of obesity were higher in Kuwait than in selected other countries.
本研究的目的是，利用分别为896名和1730名受试者的两个独立横断面样本，比较科威特成年男性（年龄≥18岁）体重指数（BMI，单位：kg/m²）和肥胖状况随时间的变化。这两个样本分别于1980 - 1981年和1993 - 1994年抽取，用于营养评估和肥胖患病率研究。样本取自初级卫生保健（PHC）诊所，测量了体重指数（BMI）以及肥胖情况，肥胖定义为BMI＞25（1级）和＞30（2级）kg/m²。研究结果显示，平均BMI（kg/m²）以及1级和2级肥胖（BMI＞25和＞30 kg/m²）的患病率分别增加了10（2.5 kg/m²）、20.6%和15.4%。在控制了两个研究时期之间的社会人口统计学差异后，1993 - 1994年的平均BMI比1980 - 1981年高2 kg/m²，两个时期之间肥胖（BMI＞25和＞30 kg/m²）的患病率也有所增加（OR分别为2.1，95%CI 1.7 - 2.7和OR为1.9，95%CI 1.5 - 2.4）。总之，1980 - 1981年至1993 - 1994年期间，科威特男性的BMI和肥胖患病率有所增加，原因是现代化、富裕以及随之而来的久坐生活方式的改变。科威特BMI和肥胖患病率随时间的变化率高于其他一些选定国家。
