对儿童肥胖症日益流行的警告，使人们把注意力集中在可能导致不健康体重的个人生活方式行为上。更远的预测因素，如母亲就业，也可能涉及，因为职业母亲很少有时间监督孩子的日常活动。这项研究使用了澳大利亚儿童纵向研究的两波数据来调查母亲的带薪工作时间是否会影响孩子看电视、吃零食和体育活动，并通过这些生活方式行为影响孩子在4-5岁和6-7岁时的体重。在这两个年龄段，儿童的生活方式行为都与体重状况相关。横断面分析证实，母亲工作时间较长与4-5岁儿童体重之间存在微小的直接关联，但与两年后测量的儿童体重无关。在横断面和前瞻性分析中，与没有工作或全职工作的母亲的孩子相比，兼职母亲的孩子看电视的时间更少，超重的可能性也更小。虽然相关性很小，但在调整了母亲体重、家庭收入和其他因素后，它们仍然显著。母亲的工作时间与其幼儿的体重状况之间的直接和间接关系的结合，进一步支持了对家庭友好的工作政策的呼吁，这是促进健康的家庭生活方式和幼儿福祉的重要手段。(c) 2010 Elsevier Ltd.版权所有。
Alarm about the increasing prevalence of childhood obesity has focussed attention on individual lifestyle behaviours that may contribute to unhealthy weight. More distal predictors such as maternal employment may also be implicated since working mothers have less time to supervise children's daily activities. The research reported here used two waves of data from the Longitudinal Study of Australian Children to investigate whether mothers' hours in paid work shape young children's television viewing, snacking and physical activity, and through those lifestyle behaviours, children's weight at ages 4-5 years and 6-7 years. At both ages, children's lifestyle behaviours were interrelated and associated with weight status. Cross-sectional analysis confirmed small, direct associations between longer hours of maternal employment and child weight at age 4-5 years, but not with child's weight measured two years later. In both the cross-sectional and prospective analyses, the children of mothers who worked part-time watched less television and were less likely to be overweight than children of mothers who were not employed or who worked full-time. While associations were small, they remained significant after adjustment for maternal weight, household income and other factors. The combination of direct and indirect relationships between mothers' work hours and the weight status of their young children provides additional support to calls for family-friendly work policies as an important means for promoting healthy family lifestyles and early childhood wellbeing.
