摘 要: | 目的 探索我国学龄儿童奶类摄入水平与超重肥胖关系。方法 采用多阶段整群抽样,选取中国八地区742名学龄儿童,展开横断面调查。采用多重线性回归和多元Logistic回归分析学龄儿童奶类摄入水平与超重肥胖相关指标间的关系。结果 调查儿童超重、肥胖率分别为16.5%和9.0%。奶类消费者占总数84.4%,酸奶消费者(71.0%)高于全脂液体奶消费者(58.6%)及低脂脱脂奶消费者(18.9%)。调查儿童奶类总摄入程度和全脂液体奶摄入程度与年龄别体质指数Z评分(body mass index for age Z-score,BAZ)均呈正相关(均有P<0.05)。结论 学龄儿童奶类总摄入程度及全脂液体奶摄入程度与BAZ呈正相关,建议该人群适当增加低脂脱脂奶和酸奶的摄入比例。

Abstract: | Objective To explore the dairy intake and its relationship with overweight and obesity in school-age children in China. Methods A cross-sectional survey was conducted among 742 school-age children from eight areas of China chosen by multi-stage cluster sampling. Multiple linear regression and multivariable logistic regression analyses were used to assess associations mentioned above. Results The rates of overweight and obesity of school-age children were 16.5% and 9.0%, respectively. The total percentage of dairy consumers was 84.4%. Among all consumers, the proportion of yogurt consumers (71.0%) was much higher than that of whole milk consumers (58.6%) and lowfat or skim milk consumers (18.9%). Total milk intake levels and whole milk intake levels were positively associated with body mass index for age Z-score (BAZ) (all P<0.05). Conclusions There are positive associations between total milk intake levels, whole milk intake levels and BAZ. It is suggested that school-age children should increase the intake ratio of lowfat or skim milk and yogurt appropriately. |
