    Abstract:
    OBJECTIVE: To evaluate the impact of menarche age (MA) on obese status in late puberty (LP) and mid-life (ML) females. METHODS: 2035 girls aged 16 to 18 years were selected from a Beijing Child and Adolescent Metabolic Syndrome (BCAMS) study, which was performed from April to October in 2004, as the LP study population. 479 women aged 41 to 52 years were from the Fetal Origin of Adult Disease (FOAD) cohort, which established in 1995 to 2001, as the ML study population. Based on the 25 and 75 percentile of MA of each population, all subjects of LP and ML were divided into early, middle, and late matured groups, respectively. Overweight and obesity were defined by Chinese age-, gender-specific BMI criteria for LP girls, and Chinese BMI criteria for ML women while central obesity was defined by the waist-to-height ratio (WHtR) cutoff of 0.5. Multiple linear regression was used to explore the associations between MA and BMI, waist circumference (WC) and WHtR. The impact of early menarche on obese status in late life was estimated by odds ratio (OR) using logistic regression analyses. RESULTS: The prevalence of overweight and obesity increased with the decrease of MA in both LP and ML population. When MA had a one-year advance, a 0.58 kg/m2 increase in BMI and a 1.1 cm increase in WC during LP, and a 0.35 kg/m2 increase in BMI and a 0.6 cm increase in WC during ML were observed. After adjustment for age, residence area and life style related variables, those who experienced earlier menarche were at higher risk of suffering from obesity in LP (OR :8.740, 95% CI: 3.653-20.911) and during ML (2.498, 1.145-5.453) when compared to those with later menarche. We also noticed that the risk increased for central obesity [LP: 14.280 (3.223-63. 267), ML: 15.604 (1.821-133.679)]. CONCLUSION: Menarche age appeared to be an independent predictor for obese status in LP and ML among women.
