Table 5. Adjusted association between risk factors for cognitive impairment and individual SES.
| Models | Adjusted factors | HR | 95% CI | Differences of HR | % of reduction |
|---|---|---|---|---|---|
| Unadjusted model | 2.1 | 1.97–2.28 | |||
| Model 1 | Age, sex, education, and family history of dementia | 1.8 | 1.62–1.88 | 0.3 | 14.3 |
| Model 2 | Model 1 + cardiovascular risk factors (hypertension, diabetes, hyperlipidemia, cardiac disease, and stroke) | 1.7 | 1.59–1.85 | 0.4 | 19.0 |
| Model 3 | Model 1 + health-related behaviors (smoking, alcohol, and exercise) | 1.7 | 1.61–1.87 | 0.4 | 19.0 |
| Model 4 | Model 1 + social relationships (marital status and living situation) | 1.7 | 1.56–1.84 | 0.4 | 19.0 |
| Model 5 | Model 1 + cardiovascular risk factors + health-related behaviors + social relationships | 1.6 | 1.53–1.80 | 0.5 | 23.8 |
SES = socioeconomic status, HR = hazard ratio, CI = confidence interval.
