    Author: Neufeld LM, Hernández-Cordero S, Fernald LC, Ramakrishnan U.

    Abstract:
    OBJECTIVE: To document the changes in BMI and the prevalence of overweight and obesity in young women living in poverty in a semi-urban community in Mexico. METHODS AND PROCEDURES: Women who had previously participated in a longitudinal research study (1997-2000) were re-assessed in 2005. Anthropometric measurements were obtained using standard procedures, and socio-demographic questionnaires were administered. Total and annual rate of change in BMI and change in the prevalence of overweight and obesity (BMI > or = 25.0 and > or =30.0) were estimated. RESULTS: Mean age in 2005 was 30.0 +/- 5.7 years (n = 683) and time between recruitment and follow-up was 6.4 +/- 1.0 years. Mean change in BMI was +3.6 +/- 2.7 (range -8.2 to +14.6). In 2005, 500 (73.2%) women were overweight, up from 263 (38.5%) in the original assessment. The prevalence of obesity tripled over the follow-up period (from 9.8% to 30.3%). The mean annual rate of change in BMI was +0.6 (+/-0.4). After adjustment for age and parity at baseline, an annual rate of change of BMI above the sample median (>0.5) was associated with lower levels of formal education. DISCUSSION: The annual increase in the prevalence of overweight and obesity in this sample is double that which was reported at a national level in Mexico. An understanding of the determinants of this rapid increase among the women living in poverty in Mexico is urgently needed.
