Hazard ratios for suicide mortality per sex-specific SD of body mass index.

Note: Body mass index was pre-adjusted for age, sex and HUNT wave and standardised by the sex-specific residual standard deviation. All models were adjusted for parental date of birth and full adjustment included additional adjustment for parental education. Parental age was used as the time axis. Models for combined parents were additionally adjusted for parental sex and used robust standard errors clustered by offspring identity. Maternal and paternal hazard ratios were compared by adding an interaction between parental sex and the exposure to the combined model and reporting the p-value from a Z-test of its coefficient. There were 34 suicide deaths among 32,457 mothers and 101 suicide deaths among 27,753 fathers.
