| 目的 探讨饮食偏好及行为对中小学生超重或肥胖的影响.方法 采用病例对照研究方法,病例为广州市28所中小学中年龄为6～19岁的所有超重或肥胖学生,对照为同校同年级随机抽取的1～2个班中所有体重正常者.饮食偏好和行为采用自编问卷调查,对饮食偏好和行为按由少到多或由不喜欢到喜欢分为4个水平;通过测胃身高和体重计算BMI并进行营养状况的分类;采用两分类logistic回归分析筛选中小学牛超重或肥胖的影响因素. 结果 共调查7136人,问卷有效者5755人中超重或肥胖者为1947人,体重正常者2136人.单因素分析超重或肥胖的风险,很喜炊吃蔬菜、水果或糖果及夜宵者是不喜欢者的0.60～0.69倍;对食物挑剔多者是极少挑剔者的0.50倍;而很喜炊吃猪肉、牛羊肉和油炸食物者分别是不喜欢者的1.84、1.30和1.26倍;以及吃饭速度快者足慢者的5.14倍(P值均<0.05).在控制年龄、性别、家庭社会经济因素、父母体型后,对蔬菜与夜宵的偏好、挑剔食物以及进食速度4个指标对超重或肥胖的影响依然具有统计学意义.与不喜欢蔬菜或夜宵、不挑剔食物或进食速度慢者相比,喜欢蔬菜或夜宵、挑剔食物、进食速度快者对超重或肥胖影响的比值比(OR)及95%CI分别为0.55(0.42～0.73),0.48(0.35～0.65),0.50(0.39～0.65)和4.32(3.23～5.80). 结论减慢进食速度与多吃蔬菜有利于预防中小学生超重或肥胖. |

The adjusted odds ratios (OR) and 95% confidence intervals (95% CI) of the above items became 0.55 (0.42-0.73), 0.48 (0.35-0.65), 0.50(0.39-0.65),and 4.32(3.23-5.80) as compared to the relevant lowest categories, respecively.
