Parental body composition, physical activity (PA) and sedentary time (ST) have been linked with offspring body weight and health. However, independent contributions of body composition, PA and ST of both parents on growth trajectories of their offspring, taking into account sex differences, has not been investigated.
A total of 114 mother-father-child triads were included for analyses. Parental weight, height, PA and ST were objectively measured at 12 weeks of gestation. Gestational weight gain (GWG) and birthweight and -length were obtained from medical records. Offspring weight and length were measured repeatedly until 1 year of age. Longitudinal linear mixed models, stratified by offspring sex, were used to analyse the association between parental characteristics and offspring growth.
GWG (positive association), maternal moderate-to-vigorous PA (negative association) and paternal ST (positive association) were associated with weight trajectories in girls but not in boys. Parental characteristics were not associated with offspring length trajectories.
This study highlights the contribution of parental lifestyle characteristics on weight trajectories of their daughters during the first year of life. The paternal impact stresses the need to further investigate health behaviours of expecting fathers in relation to offspring health. Family-based interventions are needed with a focus on increasing PA and limiting ST in both parents.
父母的身体成分、身体活动（PA）和久坐时间（ST）与子女的体重和健康有关。然而，考虑到性别差异，父母双方的身体成分、PA 和 ST 对其子女生长轨迹的独立影响尚未得到调查。
共有 114 个母婴-儿童三人组被纳入分析。在妊娠 12 周时，对父母的体重、身高、PA 和 ST 进行了客观测量。从医疗记录中获得了妊娠增重（GWG）、出生体重和长度。在 1 岁之前，反复测量了子女的体重和长度。根据子女的性别，使用纵向线性混合模型来分析父母特征与子女生长之间的关联。
GWG（正相关）、母亲中等强度至剧烈 PA（负相关）和父亲 ST（正相关）与女孩的体重轨迹有关，但与男孩无关。父母的特征与子女的长度轨迹无关。
本研究强调了父母生活方式特征对女孩在生命第一年体重轨迹的影响。父亲的影响强调了需要进一步调查准父亲的健康行为与子女健康之间的关系。需要以增加父母双方的 PA 和限制 ST 为重点，开展基于家庭的干预措施。
