To analyze the relationship between maternal height, offspring birth weight, and adiposity at 6-10 years of age in a sample of 197 mother-child dyads from Merida, Mexico.
During 2008-2009 and 2011-2013, measurements were taken of maternal height and weight; and height, waist circumference (WC), and skinfolds (triceps, subscapular, and suprailiac) of their children. Participant body composition was estimated using a bioelectrical impedance analyzer. A questionnaire was applied to document household socioeconomic conditions. Multiple linear regression models were used to study the association between maternal height, offspring birth weight and fat mass index (FMI), WC, and sum of skinfolds (SumSkfZ) in boys and girls, separately.
After adjusting for child age and household socioeconomic conditions, maternal height was identified to be significantly associated (p < .05) with FMI, WC, and SumSkf only in boys. In all models, child adiposity was inversely related to maternal height. Offspring birth weight was not associated with any adiposity parameter.
The results suggest that maternal nutritional history as reflected in short maternal stature is associated with higher body fat in children, and that male offspring are more vulnerable to intergenerational influences.
分析来自墨西哥梅里达的197对母婴样本中，母亲身高、后代出生体重与6至10岁时肥胖程度之间的关系。
在2008 - 2009年以及2011 - 2013年期间，测量了母亲的身高和体重；以及其子女的身高、腰围（WC）和皮褶厚度（肱三头肌、肩胛下和髂上）。使用生物电阻抗分析仪估算参与者的身体成分。应用一份问卷记录家庭社会经济状况。分别使用多元线性回归模型研究母亲身高、后代出生体重与男孩和女孩的脂肪量指数（FMI）、腰围和皮褶厚度总和（SumSkfZ）之间的关联。
在对儿童年龄和家庭社会经济状况进行调整后，仅在男孩中发现母亲身高与FMI、腰围和皮褶厚度总和显著相关（p < 0.05）。在所有模型中，儿童肥胖程度与母亲身高呈负相关。后代出生体重与任何肥胖参数均无关联。
结果表明，母亲身材矮小所反映的母亲营养史与儿童较高的体脂有关，并且男性后代更容易受到代际影响。
