This study sought to analyze the effect of work-to-family conflict (demands from work that affect one's family/personal life), family-to-work conflict (demands from family/personal life that affect work), and lack of time for self-care and leisure due to professional and domestic demands on the incidence of weight gain and increase in waist circumference by gender in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Our study included 9,159 ELSA-Brasil participants (4,413 men and 4,746 women) who attended baseline (2008-2010) and the first follow-up visit (2012-2014). Weight gain and increase in waist circumference were defined as an annual increase ≥ 75th percentile, i.e., ≥ 1.21kg/year and ≥ 1.75cm/year, respectively for women; and ≥ 0.96kg/year and ≥ 1.41cm/year respectively for men. Associations were estimated by Poisson regression applying robust variance with the R software. Analyses were stratified by gender and adjusted for socioeconomic variables. Adjusted models showed a higher risk of weight gain among women who reported family-to-work conflict frequently and sometimes (relative risk - RR = 1.37 and RR = 1.15, respectively) and among those who reported frequent lack of time for self-care and leisure (RR = 1.13). Among men, time-based work-to-family conflict (RR = 1.17) and strain-based work-to-family conflict (RR = 1.24) were associated with weight gain. No associations were observed between work-family conflict domains and increase in waist circumference. These findings suggest that occupational and social health promotion programs are essential to help workers balance work and family life to reduce weight gain.
在巴西成人健康纵向研究（ELSA - Brasil）中，本研究旨在分析工作与家庭冲突（工作需求对个人家庭/私人生活产生影响）、家庭与工作冲突（家庭/私人生活需求对工作产生影响）以及因职业和家庭需求导致的自我护理和休闲时间不足对不同性别人群体重增加和腰围增长发生率的影响。我们的研究纳入了9159名ELSA - Brasil参与者（4413名男性和4746名女性），他们参加了基线调查（2008 - 2010年）和首次随访（2012 - 2014年）。体重增加和腰围增长分别定义为年增幅≥第75百分位数，即女性分别为≥1.21千克/年和≥1.75厘米/年；男性分别为≥0.96千克/年和≥1.41厘米/年。采用R软件通过泊松回归并应用稳健方差估计关联。分析按性别分层，并对社会经济变量进行了调整。调整后的模型显示，经常和有时报告家庭与工作冲突的女性以及经常报告缺乏自我护理和休闲时间的女性体重增加风险较高（相对风险 - RR分别为1.37和1.15）。在男性中，基于时间的工作与家庭冲突（RR = 1.17）和基于压力的工作与家庭冲突（RR = 1.24）与体重增加有关。未观察到工作 - 家庭冲突领域与腰围增长之间存在关联。这些发现表明，职业和社会健康促进计划对于帮助员工平衡工作和家庭生活以减轻体重增加至关重要。
