|Odds ratio (95%CI)|
|Age at menarche||Model 1||Model 2||Model 3||Model 4|
|Less than 12 years||Ref.||Ref.||Ref.||Ref.|
|12 to less than 13 years||0.72 (0.54-0.96)||0.71 (0.53-0.96)||0.73 (0.54-0.99)||0.71 (0.52-0.97)|
|13 years or above||0.64 (0.48-0.84)||0.64 (0.49-0.85)||0.67 (0.50-0.88)||0.65 (0.49-0.87)|
Model 1: unadjusted. Model 2 adjusted for Group 1 (i.e. area of residence, living with both parents vs. single parent or a relative). Model 3: adjusted for Group 1 and Group 2 (i.e. presence of disease condition that limits physical activity, amount of running/jogging over the past year, number of hours spent reading/doing homework during weekdays). Model 4: adjusted for Group 1, Group 2 and Group 3 (frequency of dinners prepared away from home, frequency of fast-food intake, frequency of eggs intake, number of servings per day (divided into tertiles) of pasta and rice, number of servings per day of salty snacks and sweets).
