Gender and care: Does gender modify the mental health impact of adolescent care?

Young carers are people aged 25 years or less who deliver unpaid informal care to a family or a friend living with a physical or mental illness, a disability, problems related to alcohol/substance use or an elderly relative. Young caring has negative impacts on the mental health of adolescents. Gender patterns underpinning this association have not been explored. We examined gender differences in the mental health effect of informal care among Australian adolescents. We used data from the Longitudinal Study of Australian Children (LSAC). Participants were categorised as non-carers or young carers at 14/15 years old. Although we acknowledge that gender is non-binary, information about gender identity was not collected in LSAC during adolescence. We used the study child's sex as reported at age 14/15 years to categorise adolescents as boys or girls. Mental health was measured using the Kessler Psychological Distress scale (K10) at ages 18/19. We conducted multivariable linear regression models and assessed effect modification by fitting an interaction term between gender and informal care. Informal care was associated with poorer mental health among boys (β: 0.97, 95%CI: -0.01, 1.95), and girls (β: 1.66, 95%CI: 0.63, 2.69). Overall, in comparison to boy non-carers, girl carers had the highest level of distress (β: 4.47; 95%CI: 3.44, 5.51), yielding high predicted scores of K10. While the mental health effects of young care were stronger for girls, there was limited evidence of effect modification as the difference in mental health disparities due to informal care between girls and boys was small (β: 0.69) with high uncertainty levels (95%CI: -0.72, 2.11). Psychological distress scores were higher for girls than boys in both caring categories. Support strategies should focus on identifying and supporting boy and girl carers to reduce the adverse mental health impact of young informal care.
