The contribution of childhood circumstances, current circumstances and health behaviour to educational health differences in early adulthood

Table 3 Age- and gender-adjusted differences in poor SRH between the high and the primary educational category^a, adjusting for childhood circumstances, current circumstances and behavioural factors.

Adjusted factors	Educational level	High	Primary
		OR [95 CI]	% reduction in OR^b	Proportion shared %
Base model^c	1.00	4.69 [2.63–8.32]
Childhood circumstances	1.00	3.80 [2.00–7.23]	24
Current circumstances	1.00	4.41 [2.29–8.49]	8
Behavioural factors	1.00	3.00 [1.60–5.61]	46
Childhood and current circumstances	1.00	3.64 [1.78–7.41]	28
Childhood circumstances and behavioural factors	1.00	2.65 [1.72–2.02]	55
All	1.00	2.61 [1.17–5.83]	56
Shared effect of current and childhood circumstances (%)			(24+8)-28 = 4
Shared effect of behavioural factors and childhood circumstances (%)			(24+46)-55 = 15
Proportion of the effect of childhood circumstances shared with current circumstances (%)				4/24 = 17
Proportion of the effect of childhood circumstances shared with behavioural factors (%)				15/24 = 63

Odds ratios (OR) with 95% CI:s and percentage reduction (%). Shared effects of behavioural factors/current circumstances and childhood circumstances (%) and the proportion (%) of the effect of childhood circumstances shared with current circumstances/health behaviour.
a Reduction % and shared effects not caluculated for the middle educational category as it did not differ significantly from the reference category in the base model
b Reduction % was calculated: [(OR_{(base model)}-OR_{(base model+intermediated factors)})/(OR_{(base model)}-1)]
c Adjusted for age and gender
