Partner loss and its effect on frailty trajectories: results from the 13-year follow-up Survey of Health, Ageing and Retirement in Europe (SHARE).

This study revealed that partner loss is followed by elevated frailty. However, while women's frailty tended to recover from partner loss over time, men's frailty remained elevated. Notable individual differences in the response of frailty trajectories to partner loss suggest the existence of effect modifiers.
