Using data from the Behavioral Risk Factor Surveillance System, this study describes trends in the prevalence of overweight between 1987 and 1993.
Data were examined from 33 states participating in an ongoing telephone survey of health behaviors of adults (n = 387,704). Self-reported weights and heights were used to calculate sex-specific prevalence estimates of overweight for each year from 1987 to 1993. Time trends were evaluated with the use of linear regression.
Between 1987 and 1993, the age-adjusted prevalence of overweight increased by 0.9% per year for both sexes (from 21.9% to 26.7% among men and from 20.6% to 25.4% among women). The increasing linear trend was observed in all subgroups of the population but was most notable for Black men (1.5% per year) and men living in the Northeast (1.4% per year). Secular changes in smoking and leisure-time physical activity did not entirely account for the increase in overweight.
The prevalence of overweight among American adults increased by 5% between 1987 and 1993. Efforts are needed to explore the causes of this adverse trend and to find effective strategies to prevent obesity.
本研究利用行为危险因素监测系统的数据，描述了1987年至1993年间超重患病率的趋势。
对参与一项正在进行的成年人健康行为电话调查的33个州的数据进行了分析（n = 387,704）。使用自我报告的体重和身高来计算1987年至1993年每年按性别划分的超重患病率估计值。使用线性回归评估时间趋势。
1987年至1993年间，两性年龄调整后的超重患病率每年增加0.9%（男性从21.9%增至26.7%，女性从20.6%增至25.4%）。在所有人群亚组中均观察到线性上升趋势，但以黑人男性（每年1.5%）和居住在东北部的男性（每年1.4%）最为显著。吸烟和休闲时间身体活动的长期变化并不能完全解释超重现象的增加。
1987年至1993年间，美国成年人超重患病率上升了5%。需要努力探索这一不良趋势的原因，并找到预防肥胖的有效策略。
