奶制品摄入对中国学龄前儿童膳食质量和体格生长的影响
Effects of dairy product intake on dietary quality and growth in Chinese preschool children:A multi-center observational real-world prospective cohort study
摘要
Abstract
Objective To investigate the effects of dairy product intake on dietary quality and growth in Chinese preschool children,aiming to provide evidence-based nutritional support for improving children's dietary quality and promoting their growth.Methods A real-world study,in which 1,179 preschool children were recruited,was conducted from August 2023 to October 2023 in Shanghai,Guangdong,Hubei,Sichuan,Liaoning,and Inner Mongolia.Participating families received daily cheese sticks(45 g per child)during a 6-month follow-up period.Dietary quality was assessed using the Chinese Healthy Eating Index(CHEI).Results Both baseline and follow-up data demonstrated significantly higher CHEI scores in the high dairy intake group compared to moderate and low intake groups,with this trend persisting after confounder adjustment(P＜0.001).At baseline,children in the high dairy intake group showed significantly higher height-for-age Z-scores(HAZ)than those in the low intake group(P=0.012).After 6 months of intervention,in the high dairy intake group,HAZ gain was significantly greater in the high cheese intake group compared with the low intake group(P=0.006).Multivariate linear regression analysis,controlling for confounding factors,revealed a linear relationship between cheese intake proportion and HAZ changes(P=0.005).Additionally,the proportion of children choosing dairy products as snacks and the proportion of families focusing on nutritional components when purchasing dairy products both increased significantly(P＜0.001),as did the proportion of family members sharing cheese consumption with children(P＜0.001).Conclusion In this study,preschoolers with adequate dairy intake may have better dietary quality.Increasing total dairy intake by enhancing cheese consumption exerts a positive effect on the overall dietary quality of preschoolers and may also benefit their growth.Additionally,targeted nutritional education and provision of dairy products are effective in improving nutritional health awareness among families of preschoolers and promoting the adoption of healthy dairy-related dietary behaviors.关键词
