Midlife mental distress and risk for dementia up to 27 years later: the Nord-Trøndelag Health Study (HUNT) in linkage with a dementia registry in Norway

Table 2 Association between ≥88th percentile score on ADI–4 at baseline and dementia status 11–27 years after HUNT1 participation

	Any dementia type OR (95% CI)	p-value	Proportion of association explained by adjustment level (versus age-adjusted model) ^a
Crude (N = 436 dementia cases)	1.52 (1.15,2.01)	0.003	-
Age-adjusted (N = 436 dementia cases)	1.38 (1.04,1.82)	0.027	-
Age and gender-adjusted (N = 436 dementia cases)	1.32 (0.99,1.75)	0.055	12.8%
Fully adjusted (N = 436 dementia cases)	1.35 (1.01,1.80)	0.043	6.3%

N = 436 dementia cases.
^aAs computed by the following formula: \( 1-\frac{\mathrm{In}(adjustedOR)}{\mathrm{In}\left( age- adjustedOR\right)} \).
Bold indicates statistically significant associations (p < 0.05).
