Mental Health Across the Life Course for Men and Women in Married, Cohabiting, and Living Apart Together Relationships

This study examines the underexplored relationship between union type and mental health for married, cohabiting, and living apart together ("LAT") individuals. Further, we assess whether gender and age moderate (separately and jointly) this relationship. Using data from Wave 1 of the Generations and Gender Survey (N = 34,833), results suggest that cohabitors and LATs have worse mental health than married individuals. The negative effects of cohabiting or living apart on mental health are stronger for women than men. Young and middle-aged female LATs (to an equal magnitude) have worse mental health than married women of the same ages, while there are no such differences among older women. Middle-aged and older male LATs have worse mental health than married men of the same ages (with the larger effect found for middle-aged men), but there are no such differences among younger men. Thus, we highlight previously undocumented gender and life course dynamics of union type and mental health.
