This study assessed whether aspects of maternal mental health and well-being were associated with objective monitor-based measures of child's physical activity (PA) and sedentary behavior (SB) and the extent to which household structure (i.e., single- vs multigenerational/dual-parent) and maternal employment (i.e., full-time vs not full-time) moderated those associations.
Dyads (N = 191) of mothers and their 8- to 12-year-old children participated in the baseline wave of the Mother's and Their Children's Health study. Mothers (Mage = 40.9 yr [SD = 6.1]; 49% Hispanic) completed a battery of questionnaires to assess maternal mental health and well-being (i.e., self-esteem, life satisfaction, depressive symptoms, anxiety, perceived stress, parenting stress, financial stress, and life events stress). Children (Mage = 9.6 yr [SD = 0.9]; 54% Hispanic; 51% girls) wore an accelerometer across 1 week during waking hours to objectively measure moderate-to-vigorous PA (MVPA) and SB.
In single-parent families (n = 47), but not multigenerational/dual-parent families, mothers' parenting stress was negatively associated with child's MVPA (β = -.34, p = .02). In corrected analyses, all other aspects of maternal mental health and well-being were not related to children's activity patterns.
Parenting stress was the only maternal mental health variable associated with objective monitor-based measures of child's PA after adjusting for multiple comparisons. Results indicated weaker associations between maternal mental health and well-being and child's MVPA and SB than previously identified using subjective measures of behavior. Study findings support the need to use objective measurements of child's activity patterns to minimize potential confounding because of maternal report in evaluating child's PA and SB.
本研究评估了母亲心理健康和幸福感的各个方面是否与基于客观监测的儿童身体活动（PA）和久坐行为（SB）指标相关，以及家庭结构（即单亲家庭与多代同堂/双亲家庭）和母亲就业情况（即全职与非全职）在多大程度上调节了这些关联。
母亲及其8至12岁孩子的二元组（N = 191）参与了母亲及其子女健康研究的基线调查。母亲们（年龄中位数 = 40.9岁[标准差 = 6.1]；49%为西班牙裔）完成了一系列问卷，以评估母亲的心理健康和幸福感（即自尊、生活满意度、抑郁症状、焦虑、感知压力、育儿压力、经济压力和生活事件压力）。孩子们（年龄中位数 = 9.6岁[标准差 = 0.9]；54%为西班牙裔；51%为女孩）在清醒时间佩戴加速度计，以客观测量中度至剧烈身体活动（MVPA）和久坐行为（SB）。
在单亲家庭（n = 47）中，而非多代同堂/双亲家庭中，母亲的育儿压力与孩子的MVPA呈负相关（β = -0.34，p = 0.02）。在校正分析中，母亲心理健康和幸福感的所有其他方面与孩子的活动模式均无关联。
在进行多重比较校正后，育儿压力是与基于客观监测的儿童PA指标相关的唯一母亲心理健康变量。结果表明，与之前使用行为主观测量方法相比，母亲心理健康和幸福感与孩子的MVPA和SB之间的关联较弱。研究结果支持在评估儿童PA和SB时，需要使用儿童活动模式的客观测量方法，以尽量减少因母亲报告而产生的潜在混杂因素。
