背景：过去的研究表明，社会心理压力和痛苦可以预测久坐行为和身体活动，但很少有研究关注孕妇。我们的目的是分析加拿大孕妇的社会心理压力和痛苦与久坐行为和身体活动之间的关系。方法：我们对来自加拿大蒙特利尔的70名不同社会人口统计学的妇女在怀孕16-18周、24-26周和32-24周时的久坐行为和身体活动进行了客观分析。参与者完成了感知压力问卷，并佩戴加速度计3天，量化每天坐着的时间和步数。我们使用单变量一般线性模型来分析每次评估中感知压力与久坐行为和身体活动之间的关系。为了评估其普遍性，我们分析了加拿大社区健康调查中166,095名女性样本代表的心理困扰与自我报告的休闲时间久坐行为、交通和休闲体育活动中的每日能量消耗之间的关系。结果：在蒙特利尔队列中，我们观察到感知压力和坐着时间之间的正相关，效应大小为小到中等（偏η2 = 0.08-0.16）。我们仅在前两次评估中观察到感知压力与每日步数之间存在负相关关系，效应大小为小到中等（偏η2 = 0.08-0.11）。在全国范围内，久坐行为的关系相似，但效应较小（偏η2 = 0.02）。在全国范围内的样本中，痛苦和体育活动之间没有关系。结论：社会心理压力是久坐不动的一个危险因素，在整个怀孕期间和人口水平上都有明显的关系。与身体活动的关系不太一致，但压力可能是怀孕早期到中期身体活动不足的一个风险因素。结果可能会指导针对压力、久坐和身体活动的更全面的干预措施的发展。特别是，可以优先考虑将社会心理健康纳入减少久坐的干预措施，并在社会心理健康干预措施中纳入关于久坐行为的具体准则。
Background: Past research shows that psychosocial stress and distress predict sedentary behavior and physical activity, but few studies focus on pregnant women. Our objective was to analyze relationships between psychosocial stress and distress with sedentary behavior and physical activity among pregnant women in Canada. Methods: We analyzed objectively-measured sedentary behavior and physical activity at 16–18, 24–26, and 32–24 weeks pregnancy in a sociodemographically diverse cohort of 70 women in Montreal, Canada. Participants completed the Perceived Stress Questionnaire and wore an accelerometer for 3 days that quantified sitting time and steps per day. We used univariate general linear models to analyze relationships between perceived stress with sedentary behavior and physical activity at each evaluation. To assess generalizability, we analyzed relationships between psychological distress with self-reported leisure-time sedentary behavior and daily energy expenditure in transportation and leisure physical activities among a sample representative of 166,095 women in the Canadian Community Health Survey. Results: In the Montreal cohort, we observed a positive association between perceived stress and sitting time, with small to moderate effect sizes (partial η2 = 0.08–0.16). We observed negative relationships between perceived stress and steps per day at the first two evaluations only, with small to moderate effect sizes (partial η2 = 0.08–0.11). Relationships for sedentary behavior were similar in the nationwide sample, but with smaller effect sizes (partial η2 = 0.02). There were no relationships between distress and physical activity in the nationwide sample. Conclusion: Psychosocial stress represents one risk factor for sedentarity, with relationships evident throughout pregnancy and at the population level. Relationships with physical activity are less consistent, but stress might represent a risk factor for low physical activity in early to mid-pregnancy. Results might guide the development of more comprehensive interventions targeting stress, sedentarity, and physical activity. In particular, integrating psychosocial health into interventions to reduce sedentarity, and including concrete guidelines on sedentary behavior in psychosocial health interventions, might be prioritized.
