摘要
目的了解南京市6-18岁中小学生零食消费情况及其对体质量指数（BMI）的影响,为制定相应营养干预措施提供科学依据。方法在南京市抽取1个城区、1个郊区、1个郊县768名6-18岁学生进行食物频率问卷调查及体格测量。结果 13类零食中水果消费率最高,达99.7%。随着零食提供的能量占全天膳食总能量比例的上升,BMI呈现先降低后上升的趋势（P〈0.05）;小学男生的＂限量食用＂零食消费频率及消费量均与BMI呈正相关（r值分别为0.190,0.187,P值均〈0.05）,小学男生的饮料、膨化食品、蜜饯等消费频率与BMI呈正相关（r值分别为0.142,0.143,0.190,P值均〈0.05）;中小学生超重肥胖检出率为26.1%,二元LR法Logistic回归分析显示,油炸小食品的消费频率是中小学生超重肥胖的危险因素（OR=1.45,95%CI=1.06-1.98）。结论中小学生零食消费对营养状况存在影响,应采取营养干预措施对中小学生营养知识和健康零食消费行为进行正确引导。
Objective To understand the effect of snack consumption on BMI among 6- 18 years old students in Nanjing.Methods A total of 768 primary and middle school students of 6- 18 years old in three districts received questionnaire survey and physical examination. Results Of 13 kinds of snacks, consumption rate of fruits was highest. As energy proportion provided by snack increases, BMI showed U shape changes（ P〈 0. 05）. The consumption frequencies of drinks, puffed food and preserves in primary school boys were positively correlated with BMI（ r = 0. 190,0. 187, P〈 0. 05）. The restrained snacks frequency and consumption of primary school boys were positively correlated with BMI（ r = 0. 142, 0. 143, 0. 190, P〈 0. 05）. The prevalence of overweight and obesity was 26. 1% in the primary and middle school students. Logistic regression model showed that the consumption frequency of fried food was risk factor for overweight and obesity in primary and middle school students, OR value was 1. 45（ 95%CI = 1. 06- 1. 98）. Conclusion The snack consumption of primary and middle school students has impacts on nutritional status.Nutrition intervention should be taken to guide students＇ nutritional knowledge and healthy snacks consumption.
