Previous research has not adequately investigated the persistent influence of stressful work experiences, particularly person‐work mismatch (PWM), on later‐life physical health outcomes of working husbands and wives. Using prospective data collected from 235 working husbands and wives over a period of 27 years (1991–2017), this study examined PWM in early middle years (40–50 years of age) and body mass index (BMI) trajectories in mid‐later years (50–65 years of age) in a dyadic actor‐partner interdependence modelling framework. Results showed PWM in early middle years was related to BMI trajectories in mid‐later years, which contributed to multiple physical health outcomes in later life. Spouses' PWM influenced not only their BMI trajectories but also their partners' BMI trajectories, providing evidence for partner effects. This couple‐level BMI process over the mid‐later years was related to spouses' physical health in later years. Husbands' elevated BMI level resulted in adverse physical health outcomes. In contrast, for wives, it was the change in BMI over time that resulted in adverse physical health outcomes in their later years. These findings are particularly important for couple‐focused family interventions as they highlight the need to consider couple‐level lifestyle and behavioural factors that can safeguard spouses from the negative health consequences of PWM.
