Abbreviation: OR, odds ratio; CI, confidence interval; T, tertile; BV, bacterial vaginosis; GDQ, global diet quality, PDQ, prime diet quality
Significant values are presented in bold
Values are expressed as odds ratio (95% CIs)
Obtained from logistic regression analysis
Adjusted model: adjusted for age (years), energy intake (kcal/day), fat intake (g/day), BMI (kg/m2), physical activity (MET/h/day), familial history of BV (yes/no), pregnancy history (yes/no), menstrual cycle (yes/no), smoking history (yes/no), and number of sexual partners in previous month
