Objective: Menopausal changes are linked to increase in body fat mass and central fat distribution; nonetheless, the impact of socioeconomic position on such changes has rarely been examined. This cohort study assessed the temporal associations of socioeconomic position with changes in body mass index (BMI) and waist-to-hip ratio (WHR) among early postmenopausal women. Methods: Between 2002 and 2004, 518 Hong Kong Chinese women aged 50 to 64 and within 10 years since menopause were recruited and followed up at 3 and 5 years. Weight, height, and waist and hip circumferences were measured by trained interviewers at baseline and follow-up interviews. Socioeconomic positions including educational attainment, economic activity status and household income level, and other baseline demographic characteristics, lifestyle behaviors, and mental health status were collected based on a structured questionnaire. In total, 287 and 267 women with no general and abdominal obesity, respectively, at baseline were included in multiple regression analyses. Results: Mean intrapersonal increases in BMI and WHR between baseline and 5-year interview were 0.46 kg/m(2)and 2.80%, respectively. Women with no secondary education were 75% more likely to have a greater than-mean WHR increase than their more educated counterparts (P = 0.039). Also, having no secondary education (P = 0.041) and being a homemaker (P = 0.034) had accelerated surge in WHR. Nonetheless, baseline socioeconomic positions were not significantly associated with BMI changes. Conclusions: Socioeconomic patterning was observed for the progression of WHR among nonobese Chinese women soon after menopause. Early postmenopausal stage may be a critical window for prevention of abdominal obesity among women with a lower educational attainment.
