摘　　要：目的探究中国青少年膳食知识水平与超重肥胖关系,为预防和解决青少年肥胖提供科学依据和合理建议。方法基于2004、2006、2009、2011年中国营养与健康调查数据,获得1942名来自广西、贵州、江苏、上海、北京、重庆等地区12~18岁青少年的相关资料,利用logistic回归方法分析青少年膳食知识水平对其超重肥胖的影响,并利用多元线性回归方法分析青少年膳食知识水平的影响因素。结果 12岁年龄组青少年超重肥胖率最高,达17.1%;高收入家庭青少年超重肥胖率最高,达14.3%;男生超重肥胖率(13.60%)明显高于女生(8.1%)。logistic回归分析结果显示,青少年高膳食知识水平可显著降低青少年超重肥胖的概率(OR=0.961,95%CI=0.924~0.999,P=0.046);多元线性回归结果显示,母亲膳食知识水平对青少年膳食知识水平也有显著作用(β=0.423,95%CI=0.361~0.484,P=0.000)。结论提高青少年膳食知识水平可降低青少年超重肥胖概率,母亲膳食知识水平对青少年膳食知识水平有促进作用。Objective To investigate the relationship between dietary knowledge levels and overweight/obesity among Chinese adolescents and to provide evidences for the prevention of overweight/obesity in the population.Methods Information on 1 942 adolescents aged 12 to 18 years in Guangxi,Guizhou,Jiangsu province and Shanghai,Beijing,Chongqing municipality were extracted from the datasets of four waves of China Health and Nutrition Survey in 2004,2006,2009,and 2011.The effect of dietary knowledge levels on overweight/obesity among the adolescents was assessed with logistic regression analysis and the main factors associated with dietary knowledge level were also explored using multiple linear regression.Results Among the adolescents,the overweight/obesity rate of the boys was higher than that of the girls （13.6% vs.8.1%） and the age-specific rate was the highest （17.1%） for those aged 12 years;for the adolescents with different household economic status,the overweight/obesity rate was the highest （14.3%） in those with high family income.The results of logistic regression showed that the adolescents with a high level of dietary knowledge was significantly less likely to have overweight/obesity （odds ratio[OR]=0.961,95% confidence interval[95%CI]：0.924-0.999,P=0.046）.Multivariate linear regression revealed a significant positive correlation between the dietary knowledge level of the adolescents and their mothers （β=0.423,95%CI=0.361-0.484,P=0.000）.Conclusion The occurrence of overweight and obesity could be reduced by increasing dietary knowledge level among adolescents and high dietary knowledge of the mothers can promote the dietary knowledge level of their children.
