摘要
目的 分析 1 984～ 1 999年北京地区 2 5～ 64岁人群平均体重指数 (BMI)、超重率的变化趋势。方法 在北京地区心血管病监测人群中 ,分别进行了 5次心血管病危险因素的横断面调查。结果 1 984～ 1 999年 2 5～ 64岁人群平均BMI由 2 3 .3增加到 2 4 .0 ,超重率由 2 7.5 %增加到35 .9%。男性人群超重率由 2 3 .5 %增加到 43 .4%。男性各年龄组及城乡地区的超重率均呈增加趋势。女性人群在城乡地区的超重率呈不同变化趋势 ,城市女性超重率由 36 .0 %下降到 2 3 .3% ,农村女性超重率由 2 8.4%增加到 46 .0 %。城市人群的超重率由 2 9.1 %增加到 31 .8% ,农村人群的超重率由 2 2 .1 %增加到 49.6%。研究早期城市人群的平均BMI和超重率大于农村人群 (P <0 .0 5) ,到研究后期农村人群的BMI和超重率赶上并超过城市人群 (P <0 .0 5)。结论 城市男性和农村男女两性人群BMI和超重率均呈上升趋势 ,但农村人群的上升速度较快 。
Objective To analyse the trends of body mass index (BMI) and overweight in a population aged 25 through 64 years in Beijing. Method During 1984 to 1999, five cross sectional surveys on cardiovascular disease (CVD) risk factors were carried out in the CVD monitoring population in Beijing. The mean levels and trends of BMI as well overweight in different sexs, age groups and areas were analysed. Results (1)In the period of 1984 to 1999, the mean BMI increased from 23.3 to 24.0 (kg/m 2) in population aged 25 to 64 years, and overweight increased from 27.5 % to 35.9 %. (2) From 1984 to 1999, the prevalence of overweight increased from 23.5 % to 43.3 % in males. This increasing trend was seen in both urban and rural populations and in all age groups. Prevalence of overweight decreased from 36.0 % to 23.3 % in urban females, but increased from 28.4 % to 46.0 % in rural females. (3) From 1984 to 1999, prevalence of overweight increased from 29.1 % to 31.8 % in urban population, while 22.1 % to 49.6 % in rural population. BMI and prevalence of overweight were higher in urban than in rural ( P < 0.05 ) in 1984 to 1985 but the levels in rural were approaching and exceeding the levels in urban ( P < 0.05 ) in 1999. Conclusion Trends of BMI and overweight increased in the urban males and both males and females in the rural, while the increase of both BMI and overweight was seen more rapid in rural than in urban.
