Conclusions: 1.Cognitive protective factors for older persons when married and accompanied by a partner;2.The more life events,the more likely to cause cognitive impairment?The interaction of marital status * social activities * life events has obvious cognitive effects;3.Older men who are married and live with their spouse have better cognitive outcomes than older women who are married and live with their spouse?Older females with a better cognitive status than older males with a widow?Older persons who are married and live with their spouses have better cognitive outcomes than those who are widowed?...
