Seven-year incidence and progression of XXXX . Characterization of body fat pattern evolution in low-income Mexico City urban population.

@entity1 @entity28
BACKGROUND: There are no prospective data regarding the natural history of @entity28 in Mexico. The objective of this research was to investigate the incidence and progression of @entity28 in a low-income sector of Mexico City and to characterize evolution of body fat pattern distribution. METHODS: We carried out a population-based, prospective survey. Total on-site population was 15,532 @entity1 ; we determined as eligible all 35 to 64-year-old @entity1 and nonpregnant @entity1 for a total of 3,505. We interviewed at baseline 3,319 (94.7%) individuals and examined 2,282 (65.1%). At follow-up approximately 7 years later, we interviewed 1,764 (77.3%) subjects and examined 1,594 (69.9%). Measurements for all @entity1 included height, weight, body mass index (BMI), waist-hip circumference, and subscapular and triceps skinfold thickness. Overweight was defined as BMI > or = 25 and < or = 29.9 kg/m2, while grade 1 @entity28 was BMI >or = 30 and < or = 34.9 kg/m2, grade 2 was > or = 35 and < or = 39.9, and grade 3, > or = 40 kg/m2. RESULTS: At baseline, prevalence of overweight was 48.6%, and grade 1 @entity28 , 22.7%, grade 2, 5.1%, and grade 3 @entity28 was 1.4%; at follow-up, these were 45.2, 25.8, 6.6, and 2.3%, respectively. At baseline, mean BMI in @entity1 was 29.1 +/- 0.16 kg/m2 and in @entity1 , 27.3 +/- 0.15 kg/m2; at follow-up, it reached 29.4 +/- 0.17 kg/m2 in @entity1 and 27.4 +/- 0.16 kg/m2 in @entity1 . Waist circumference increased from mean of 99.7 +/- 0.44 cm in @entity1 to 101.2 +/- 0.42 cm; in @entity1 , mean waist circumference rose from 95.2 +/- 0.38 to 96.7 +/- 0.39 cm. CONCLUSIONS: The @entity28 epidemic in this population possesses serious proportions that increase risk for severe metabolic consequences. There is a need for intervention.
