Table 4.
PAFs for population counterfactuals of NAFLD.
| Scenario | Definition | PAF (%), 95% CI of Non-Obese Population |
PAF (%), 95% CI of Total Population |
|---|---|---|---|
| Weight loss | If those who gained weight from early adulthood could have lost weight in later adulthood (“early adulthood weight gain” group vs. “revert to non-obese” group). | 18.98 (14.18, 22.74) | 16.27 (12.16, 19.50) |
| Weight maintenance | If those who gained weight could have maintained non-obese during adulthood (“early or middle and late adulthood weight gain” group vs. “stable non-obese” group). | 31.18 (22.69, 37.76) | 26.74 (19.45, 32.38) |
| Partial prevention | If the total population maintained non-obese (BMI < 30 kg/m2) across adulthood (“stable non-obese” vs. other counterparts). | 31.10 (21.19, 38.76) | 26.67 (18.17, 33.23) |
| Comprehensive prevention | If the total population had a normal BMI (BMI < 25 kg/m2) across adulthood (“stable normal” vs. other counterparts). | 73.32 (55.03, 82.05) | 73.09 (55.62, 82.93) |
Risk estimates were adjusted for baseline age, sex, race/ethnicity, education level, family income–poverty ratio level, marital status, alcohol consumption and smoking status, chronic diseases, baseline leisure time physical activity level and HEI.
