A new study shows that marital transition can cause weight gain differently for each gender. That is, women tend to gain weight after getting married while men gain weight after divorce. The study, conducted by a sociology graduate student at Ohio State University, used data from over 10,000 respondents surveyed between 1986 and 2008. Both men and women who got married or divorced were more likely than never-married people to gain weight in the two years following their marital transition, however women were more likely to gain it following marriage and men were more likely to gain it following divorce. The researchers also found that people over age 30 were more likely to gain weight after marriage or divorce compared to those under age 30 and the risk increased as people got older.
