Ethnic identification, social disadvantage, and mental health in adolescence/young adulthood: results of a 25 year longitudinal study.
OBJECTIVE
To examine the role of cultural identity and social disadvantage/childhood adversity in a birth cohort of 984 young people studied to the age of 25.


METHODS
Data were gathered on mental health, cultural identification, socioeconomic factors and childhood adversity as part of a longitudinal study of a New Zealand birth cohort (the Christchurch Health and Development Study).


RESULTS
Those with sole Māori identity had rates of disorder that were 1.28-fold higher than those of non- Māori; those of Māori/other identity had rates of disorder that were 1.57-fold higher than non- Māori. Regression analyses suggested that the elevated rates of mental disorder among Māori were largely explained by their higher exposure to socioeconomic disadvantage and childhood adversity. But even after adjustment, being of sole Māori identity was a protective factor that reduced rates of mental disorder among Māori.


CONCLUSIONS
Risk and protective factors associated with the mental health of young Māori involve an interplay between levels of exposure to social disadvantage/childhood adversity and cultural identity, with secure cultural identity being a factor that may mitigate the effects of exposure to adversity.
