Background: Prevalence of childhood obesity represents a major public health concern, given the tracking of body weight from childhood to adult age and its health sequelae.
Objective: To describe prevalence of overweight (OW) and obesity (OB) in children at 8 years and investigate the relationship with pre-pregnancy maternal weight and weight status at 4 years.
Methods: 485 pregnant mothers recruited between 2004 and 2007 and 409 children from a population-based cohort study. Research protocol was approved by the Ethics Committee. We analysed maternal BMI, BMI at 4 and 8 years and prevalence of OW/OB according to IOTF. At 8 years, we also measured waist circumference and body composition (by electrical bioimpedance).
Results: 319 (169 boys) were studied, aged (mean (S.D.)) 8.26 (0.28) years. Table 1 shows anthropometric characteristic for the total and by sex. 4.6% mothers were underweight (BMI less than 18.5 kg/m2), 68.8% normal weight (BMI 18.5–24.9 kg/m2), 18.7% had OW (BMI 25–29.9 kg/m2) and 7.9% OB (BMI equal or more than 30 kg/m2). 20.2% children had OW or OB at 4 years. At 8 years, one to three children had OW or OB. There is positive relation between pre-pregnancy BMI and BMI at 4 and 8 years (P-trend <0.001).
| Boys N (%) | Girls N (%) | Total N (%) | ||
| BMI | Normal | 118 (69.8) | 97 (64.7) | 215 (67.4) |
| Overweight | 37 (21.9) | 38 (25.3) | 75 (23.5) | |
| Obesity | 14 (8.3) | 15 (10.0) | 29 (9.1) | |
| Waist circumference | <P90 | 134 (79.3) | 96 (64.0) | 230 (72.1) |
| >=P90 | 35 (20.7) | 54 (36.0) | 89 (27.9) | |
| Waist circumference/ Height | Normal | 44 (26.0) | 28 (18.7) | 72 (22.6) |
| Overweight | 77 (45.6) | 58 (38.7) | 135 (42.3) | |
| Obesity | 48 (28.4) | 64 (42.7) | 112 (35.1) | |
| % Body fat | <25% | 105 (70.5) | 90 (66.7) | 195 (68.7) |
| >=25% | 44 (29.5) | 45 (33.3) | 89 (31.3) |
Conclusion: High prevalence of overweight and obesity at 8 years were found, even more that at 4 years. There is a positive correlation between offspring’s weight status and pre-pregnancy maternal weight. Childhood obesity prevention should be started from pregnancy and infancy.
