肥胖已成为全球儿童和青少年的主要健康问题。本研究旨在了解1997年至2009年中国地区儿童超重和肥胖的趋势及其与家庭收入、膳食摄入量和体力活动(PA)的关系。研究采用了中国健康与营养调查的两波中国7-17岁儿童青少年横断面数据。体重和身高是按照标准化程序测量的。饮食摄入量通过连续3次24小时回顾进行评估。儿童超重和肥胖的定义是使用国际肥胖工作组推荐的身体质量指数分界值。用多元线性回归分析家庭收入与饮食摄入量和PA的关系。多因素Logistic回归分析评估超重和肥胖与家庭收入、饮食摄入量和PA的关系。儿童超重和肥胖率从1997年的12.6%上升到2009年的22.1%，特别是在中等和高收入家庭群体中，分别增加了102.7%和90.3%。在最终模型中，较高的脂肪摄入量(%能量)和中等强度的PA与超重和肥胖显著相关(优势比[OR]=1.0 1，95%可信区间[CI]：1.0 0~1.0 2，P=0.004；OR=0.99，95%CI：0.98~1.0 0，P=0.036)。1997至2009年间，中国儿童和青少年超重和肥胖的患病率有所上升。减少脂肪摄入量和增加PA可能有助于预防肥胖。
Obesity has become a major health problem among children and adolescents worldwide. This study aimed to examine the trends of overweight and obesity among childhood in China and assess their associations with family income, dietary intake, and physical activity (PA) between 1997 and 2009. Two waves of cross-sectional data of Chinese children and adolescents aged 7–17 years from the China Health and Nutrition Survey were used. Weight and height were measured following standardized procedures. Dietary intake was assessed by 3 consecutive 24-h recalls. Childhood overweight and obesity were defined using the International Obesity Task Force-recommended body mass index cut-offs. Multivariate linear regression analysis was used to examine the associations of family income with diet intakes and PA. Multivariate logistic regression analysis was conducted to assess the associations of overweight and obesity with family income, dietary intake, and PA. The prevalence of childhood overweight and obesity increased from 12.6% in 1997 to 22.1% in 2009, particularly in the medium- and high-family income groups, which increased by 102.7% and 90.3%, respectively. Higher fat intake (% energy), and moderate and vigorous PA were significantly associated with overweight and obesity in final model (odds ratio [OR] = 1.01, 95% confidence interval [CI]: 1.00–1.02, P = 0.004; and OR = 0.99, 95% CI: 0.98–1.00, P = 0.036, respectively). The prevalence of overweight and obesity among Chinese children and adolescents has increased between 1997 and 2009. Reducing fat intake and increasing PA may help obesity prevention.
