Timing and accumulation of work-related exposures may influence later life health. This study evaluates the association between women's work patterns and physical functioning. Work history and physical functioning information was collected at baseline for U.S. women ages 50 to 79 years in the Women's Health Initiative Observational Study ( = 75,507). We estimated life course workforce participation patterns using latent class analysis. Associations between work patterns and physical limitations were explored using modified Poisson regression. Compared with working continuously, women who left the workforce early had 8% increased risk and women who worked intermittently had 5% reduced risk of physical limitations later in life. The negative association with intermittent workforce participation was stronger for women with substantively complex work (9% reduced risk) than for women with nonsubstantively complex work (2% reduced risk). : Life course work patterns and characteristics may contribute to physical functioning later in life among women.
工作相关暴露的时间和积累可能会影响晚年健康。本研究评估了女性工作模式与身体机能之间的关系。在美国妇女健康倡议观察研究（n=75507）中，我们在基线时收集了 50 至 79 岁女性的工作史和身体机能信息。我们使用潜在类别分析来估计生命历程中的劳动力参与模式。使用修正后的泊松回归来探讨工作模式与身体限制之间的关联。与连续工作相比，提前离开劳动力市场的女性身体限制的风险增加 8%，间歇性工作的女性风险降低 5%。对于从事实质性复杂工作的女性（风险降低 9%），间歇性劳动力参与的负面关联强于从事非实质性复杂工作的女性（风险降低 2%）。总之，生命历程中的工作模式和特征可能会影响女性晚年的身体机能。
