The purpose of the study is to compare temporal changes in BMI, overweight (BMI > 25 Kg/m2) and obesity (BMI > 30 Kg/m2) of two independent cross-sectional samples of Kuwaitis studied in 1980-81 and 1993-94. The earlier sample of 2067 (896 men and 1171 women) and the latter sample of 3435 (1730 men and 1705 women) adult Kuwaitis (aged > or = 18 years), were drawn from primary health care (PHC) clinics and studied for nutritional assessment and for prevalence of obesity in 1980-81 and 1993-94, respectively. Weight was measured in kilograms and height in meters to obtain the body mass index (BMI), which is the weight in kilograms divided by the height in meters squared (Kg/m2). BMI > 25 and > 30 Kg/m2 were classified as overweight and obesity, respectively. The results of the study show that mean BMI (Kg/m2) increased significantly (p < 0.001) by 10.0 and 6.2% (2.5 and 1.7 Kg/m2) among men and women, respectively. Prevalence of overweight and obesity (BMI > 25 and > 30 Kg/m2) increased by 20.6 and 15.4% and by 13.7 and 8.4% among men and women, respectively. After controlling for sociodemographic differences between the two study periods, mean BMI was 2.0 and 1.6 Kg/m2 higher in 1993-94 than in 1980-81 among men and women, respectively. Prevalence of overweight and obesity (BMI > 25 and > 30 Kg/m2) also increased among both genders between the two periods (OR = 2.1 , 95% CI 1.7-2.7 and OR = 1.9, 95% CI 1.5-2.4, for men and OR = 2.2, 95% CI 1.6-3.0 and OR = 1.4, 95% CI 2.2 CI 1.0-1.9, for women). It can be concluded that the BMI, prevalence of overweight and obesity increased among Kuwaitis between 1980-81 and 1993-94, probably due to the effects of modernization, affluence, increased food consumption and the concomitant changes to sedentary lifestyles. The rate of temporal changes in BMI and obesity were higher, by comparison, in Kuwait than in selected other countries.
本研究的目的是比较1980 - 1981年和1993 - 1994年对科威特人进行的两个独立横断面样本中，体重指数（BMI）、超重（BMI>25 Kg/m²）和肥胖（BMI>30 Kg/m²）随时间的变化情况。1980 - 1981年的早期样本包括2067名成年科威特人（896名男性和1171名女性），1993 - 1994年的后期样本包括3435名成年科威特人（1730名男性和1705名女性）（年龄≥18岁），这些样本分别取自初级卫生保健（PHC）诊所，于1980 - 1981年和1993 - 1994年进行营养评估和肥胖患病率研究。体重以千克为单位测量，身高以米为单位测量，以获得体重指数（BMI），即千克体重除以米身高的平方（Kg/m²）。BMI>25 Kg/m²和>30 Kg/m²分别被归类为超重和肥胖。研究结果表明，男性和女性的平均BMI（Kg/m²）分别显著增加（p<0.001）10.0%和6.2%（2.5 Kg/m²和1.7 Kg/m²）。超重和肥胖（BMI>25 Kg/m²和>30 Kg/m²）的患病率在男性中分别增加了20.6%和15.4%，在女性中分别增加了13.7%和8.4%。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年男性和女性的平均BMI分别比1980 - 1981年高2.0 Kg/m²和1.6 Kg/m²。两个时期内，超重和肥胖（BMI>25 Kg/m²和>30 Kg/m²）的患病率在两性中也均有所增加（男性的OR = 2.1，95% CI 1.7 - 2.7；OR = 1.9，95% CI 1.5 - 2.4；女性的OR = 2.2，95% CI 1.6 - 3.0；OR = 1.4，95% CI 1.0 - 1.9）。可以得出结论，1980 - 1981年至1993 - 1994年间，科威特人的BMI、超重和肥胖患病率有所增加，这可能归因于现代化、富裕程度提高、食物消费增加以及随之而来的久坐生活方式的改变。相比之下，科威特BMI和肥胖随时间的变化率高于其他一些选定国家。
