: The association between milk-derived or dairy product intake (DPI) and the body composition (BC) of children and adolescents continues to be controversial. : This study sought to evaluate the association between the quantity and quality of DPI and the BC of Mexican children and adolescents. : A secondary data analysis of a cross-sectional population-based sample of 2104 children and adolescents (aged 4-18 years) recruited from schools in Mexico City was performed. To assess the association between the quantity and quality of DPI, evaluated by questionnaire, and BC, dual X-ray densitometry (DXA) and surrogate parameters of the fat mass index (FMI) and lean mass index (LMI) were used. The adequacy of the quantity and quality of DPI was classified according to age-specific recommendations and the sugar, sodium and fat contents of the products consumed. Relationships were assessed by means of lineal regressions adjusted for age, sex, physical activity, sleep time and screen hours. : We included a total of 1840 participants aged 4.5-18 years, 52% of whom were female. Average daily DPI was 4.0 ± 2.4 servings/day, with a predominance of milk without sugar (42.7% of DPI). The quantity and quality of DPI significantly reduced the FMI (beta = -0.1 kg/m, 95% CI -0.17 to -0.06, < 0.001 and beta = -0.17 kg/m, 95% CI -0.26 to -0.07, < 0.001). No significant relationships were seen with the LMI. : Higher quantities of good-quality DPI are associated with lower adiposity in Mexican children and adolescents.
牛奶摄入量或乳制品摄入量（DPI）与儿童及青少年身体成分（BC）之间的关联一直存在争议。本研究旨在评估墨西哥儿童及青少年DPI的数量和质量与身体成分之间的关联。对从墨西哥城学校招募的2104名儿童及青少年（4 - 18岁）的基于人群的横断面样本进行了二次数据分析。为评估通过问卷评估的DPI数量和质量与身体成分之间的关联，使用了双能X线骨密度仪（DXA）以及脂肪量指数（FMI）和去脂体重指数（LMI）的替代参数。根据特定年龄建议以及所消费产品的糖、钠和脂肪含量对DPI数量和质量的充足性进行分类。通过对年龄、性别、身体活动、睡眠时间和屏幕使用时间进行调整的线性回归来评估关系。我们共纳入了1840名4.5 - 18岁的参与者，其中52%为女性。平均每日DPI为4.0±2.4份/天，无糖牛奶占主导（占DPI的42.7%）。DPI的数量和质量显著降低了FMI（β = -0.1 kg/m，95%置信区间 -0.17至 -0.06，P < 0.001；β = -0.17 kg/m，95%置信区间 -0.26至 -0.07，P < 0.001）。与LMI未发现显著关系。高质量DPI的摄入量较高与墨西哥儿童及青少年较低的肥胖程度相关。
