According to Drefahl’s report in the journal Demography, a man who is between seven and nine years older than his wife has an 11% lower mortality rate than a man whose wife is the same age as him. However, a woman who is between seven and nine years older than her husband has a 20% greater mortality rate than if she were with a man the same age.
The article includes a nice graph,
Women marrying a partner seven to nine years younger increase their relative mortality risk by 20% compared with couples where both are the same age. But the relative mortality risk of a husband who is seven to nine years older is reduced by 11%. Source: Sven Drefahl
Considering that the research was done in Germany, does that apply to people in other countries?
