- Data are expressed as prevalence ratio and 95% confidence interval (CI); Poisson regression to Model 1; Group peri-menarche: Less than 2 years since menarche; Group post-menarche: 2 years or more since menarche; Multivariate Poisson regression to models adjusted for chronological age (increase of 1 year); ethnicity (non-white), smoking (experimented), alcohol (experimented), waist circumference and nutritional status (overweight and obesity); PR = Prevalence ratios (menarche B in relation to menarche A); p value ≤ 0.05 and 95% CI; Altered HOMA-IR: ≥ 3.16; hyperinsulinemia: > 15 mU/mL; Model 1—unadjusted; Model 2—adjusted for age and ethnicity; Model 3—adjusted for age, ethnicity, smoking, alcohol, and waist circumference; Model 4—adjusted for age, ethnicity, smoking, alcohol and nutritional status
- Statistically significant prevalence ratios are in bold (p < 0.05)
