Gender and Family Disparities in Suicide Attempt and Role of Socioeconomic, School, and Health-Related Difficulties in Early Adolescence

Table 4

Suicide attempt risk associated with family structure and covariates contribution among girls (𝑛=781): adjusted hazard ratio (HR), 95% confidence interval (CI), and covariates contribution (%)^a.

	Parents divorced/separated and reconstructed family; (versus intact family)			Single parent and other situations; (versus intact family)
	HR	95% CI	%^a	HR	95% CI	%^a
Model 1: age-adjusted HR	3.05 ***	1.94–4.77	100	2.98 ***	1.74–5.11	100
Model 2: +socioeconomic factors^b	2.19 ***	1.37–3.49	42	2.33 **	1.31–4.13	33
Model 3: +school and mental difficulties and sustained violence^b	1.81 *	1.11–2.93	60	2.25 **	1.27–3.99	37
Model 4: +unhealthy behaviors^b	1.63	0.99–2.66	9	1.73	0.95–3.16	63

^∗𝑃<0.05, **𝑃<0.01, ***𝑃<0.001. Bold types: significant HR.
^aCovariates contribution (%) = reduction of (positive %) or increase (negative %) in HR computed with the following formula: (HR_{model 1} − HR_{extended model}) /(HR _{model 1} − 1).
^bSee Table 2.
Note: The age-adjusted HRs were nonsignificant for boys (1.58, 95% CI 0.89–2.80, and 1.28, 95% CI 0.56–2.92, respectively).
