Objective.分析不同民族男性青少年肥胖随时间的变化趋势。方法.在征兵中心接受体检作为征兵筛选一部分的受试者的基于人群的国家数据。受试者为1950-1986年出生的17岁犹太男性（n = 1 140 937）。身体质量指数（BMI）数据由医生测量（不穿衣服和鞋子）。我们计算了各种族人群每年的肥胖患病率（BMI 29.4或更高）。使用多项逻辑回归模型来估计种族和其他危险因素对肥胖可能性的影响。结果随着时间的推移，所有族裔青少年群体的肥胖率都有所上升。多项回归分析显示，与其他群体相比，亚非血统的人患肥胖症的可能性较低。然而，与其他群体相比，这一族裔群体的肥胖率随着时间的推移增加得更大。结论这项研究的一个重要发现是，随着时间的推移，肥胖的可能性在时间趋势上存在差异。在亚非裔青少年中，与其他青少年群体相比，肥胖的可能性随着时间的推移急剧增加。因此，以色列的卫生服务部门应将亚非血统视为一个独特的风险因素，并采取针对性干预措施，以防止这些青少年未来肥胖。
Objective. To analyze the temporal trends of obesity over time among male adolescents of different ethnic origins. Methods. Population-based national data of subjects presenting at recruitment centers for medical examinations as part of screening for military draft. Subjects were 17-year-old Jewish males (n = 1 140 937) born in the years 1950-1986. Data on body mass index (BMI) were measured (without clothing and shoes) by physicians. We calculated the prevalence of obesity (BMI 29.4 or higher) for each year by ethnic origin group. A Multinomial logistic regression model was used to estimate the effects of ethnic origin and other risk factors on the likelihood of obesity. Results. Over time, obesity rates have risen among all ethnic groups of adolescents. Multinomial regression analysis showed a lower likelihood of obesity among those of Asia-Africa origin as compared with other groups. However, obesity rates have increased more significantly over time among this ethnic group compared with the other groups. Conclusion. A significant finding of this study is the disparities in temporal trends in the likelihood of obesity over time. Among adolescents of Asia-Africa origin the likelihood of obesity increased more steeply over time compared with other groups of adolescents. Health services in Israel should thus consider Asia-African origin as a distinct risk factor and target interventions to prevent future obesity among these adolescents.
