背景：幼儿有不符合体力活动建议的风险。从生命的第一年确定影响幼儿身体活动水平的因素可能有助于制定有针对性的干预策略。本研究的目的是研究幼儿的身体活动的早期儿童预测跨域的母亲的信念和行为，婴儿的行为和家庭environment.Methods：从206名幼儿（53%的男性）参加墨尔本InfFANT计划的数据收集在2008 - 2010年，并在2012年进行分析。母亲在孩子4个月（T1）和9个月（T2）时完成了身体活动预测因素的调查。身体活动进行了评估，ActiGraph GT 1 M加速计在19个月（T3）龄。结果：一个婴儿的行为在T1和一个母亲的信念和两个婴儿的行为在T2显示协会与身体活动在T3，并包括在多变量分析。在调整了孩子开始走路的年龄和母亲的教育之后，与4个月大的类似年龄的婴儿一起度过的时间（β = 0.06，95% CI [0.02，0.10]）和9个月时与母亲一起进行体力活动的时间（β = 0.06，95%CI [0.01，0.12]）预测儿童在19个月龄时的体力活动。结论：促进同伴互动和母子共同参与体力活动可以作为一种健康促进策略，以增加幼儿的体力活动。未来的研究需要确定其他未在本研究中评估的早期生活预测因素，并检查这些因素是否可以预测生命后期的身体活动。
Background: Young children are at risk of not meeting physical activity recommendations. Identifying factors from the first year of life which influence toddlers' physical activity levels may help to develop targeted intervention strategies. The purpose of this study was to examine early childhood predictors of toddlers' physical activity across the domains of maternal beliefs and behaviours, infant behaviours and the home environment.Methods: Data from 206 toddlers (53% male) participating in the Melbourne InFANT Program were collected in 20082010 and analysed in 2012. Mothers completed a survey of physical activity predictors when their child was 4-(T1) and 9-months old (T2). Physical activity was assessed by ActiGraph GT1M accelerometers at 19-months (T3) of age.Results: One infant behaviour at T1 and one maternal belief and two infant behaviours at T2 showed associations with physical activity at T3 and were included in multivariate analyses. After adjusting for the age at which the child started walking and maternal education, the time spent with babies of a similar age at 4-months (beta = 0.06, 95% CI [0.02, 0.10]) and the time spent being physically active with their mother at 9-months (beta = 0.06, 95% CI [0.01, 0.12]) predicted children's physical activity at 19-months of age.Conclusions: Promotion of peer-interactions and maternal-child co-participation in physical activity could serve as a health promotion strategy to increase physical activity in young children. Future research is required to identify other early life predictors not assessed in this study and to examine whether these factors predict physical activity in later life stages.
