1997―2011年中国7~17岁儿童青少年含糖饮料摄入与中心性肥胖的关系

Study on the relationship between sugar-sweetened beverage intake and central obesity in children and adolescents aged 7-17 years from 1997 to 2011 in China

目的探讨含糖饮料摄入与儿童青少年中心性肥胖的关系。方法利用"中国健康与营养调查"项目公开数据库中1997―2011年的横断面调查数据,分析中国7~17岁儿童青少年含糖饮料摄入与中心性肥胖的关系。根据腰围划分为正常组和中心性肥胖前期/中心性肥胖组,采用χ^(2)检验比较不同组间差异,采用多因素Logistic回归分析模型分析含糖饮料对儿童青少年中心性肥胖的影响。结果1916名7~17岁儿童青少年中,含糖饮料摄入频率≥3次/周、1~2次/周、1~3次/月和<1次/月分别为389人(20.3%)、712人(37.2%)、563人(29.4%)和252人(13.2%)。共计731例(38.2%)发生中心性肥胖前期/中心性肥胖,调整相关混杂因素后,与摄入含糖饮料<1次/月组相比,≥3次/周组增加68.0%的肥胖风险(95%CI:1.194~2.346,P=0.003);年龄、性别对含糖饮料摄入频率和中心性肥胖的关系无统计学影响。结论含糖饮料摄入频率增高会增加儿童青少年中心性肥胖发生风险。

Objective To investgate the relationship between sugar-sweetened beverage intake and central obesity among children and adolescents.Methods We used the cross-sectional survey data from 1997 to 2011 in the open database of the"China Health and Nutrition Survey"project,and this study analyzed the relationship between sugar-sweetened beverage intake and central obesity among Chinese children aged 7-17 years.All participants were divided into normal group and pre-central obesity group/central obesity group by the waist circumference.We used the Chi-square test to compare the differences between different groups,and multivariate Logistic liner regression analysis model was used to analyze the influence of sugary drinks on central obesity in children and adolescents.Results Among 1916 children aged 7 to 17 years,389(20.3%)had more than or equal to 3 times of intake of sugar-sweetened beverages per week,712(37.2%)had 1-2 times per week,563(29.4%)had 1-3 times per month and 252(13.2%)had less than once a month group.A total of 731 cases(38.2%)developed pre-central obesity/central obesity.After adjusting for related confounding factors,compared with the group who consumes sugary drinks less than once a month group,the group had more than or equal to 3 times a week increased the risk of obesity by 68.0%(95%CI:1.194-2.364,P=0.003).Besides,age and gender had no significant effect on the relationship between the frequency of sugar-sweetened beverage intake and central obesity.Conclusion Higher frequency of sugar-beverage intake can increase the risk of central obesity in children and adolescents.
