Insights
Excess body weight in children begins early, with higher prevalence in males by age 14. This trend, linked to lifestyle, necessitates early intervention strategies.
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Developmental Pediatrics
Context:
- Childhood obesity is a growing global concern.
- Understanding the onset and progression of excess body weight is crucial for effective public health strategies.
Purpose:
- To analyze the chronological development of overweight and obesity in children.
- To inform public awareness and intervention across family, school, and health sectors.
Summary:
- A study tracked 604 children from birth to 14 years, measuring weight, height, and BMI.
- Excess body weight was identified by age 4 and increased progressively, with higher prevalence in males (29%) versus females (12.8%) by age 14.
- Body Mass Index (BMI) Z-scores indicated overweight or obesity starting at age 4 for those with excess weight at 14.
Impact:
- Findings suggest excess body weight originates in early childhood, influenced by family dietary habits.
- Interventions should target early life stages and address lifestyle factors during school years and adolescence.
Objective:
To analyze the chronological evolution of excess body weight (overweight and obesity) in order to raise public awareness within the different areas of intervention (family, school, business environment, health services) and to take effective actions.
Material And Methods:
Weight, height and body mass index (BMI) of 604 healthy subjects (307 males and 297 females) have been recorded at birth and at the age of 1, 2, 3, 4, 6, 8, 10, 12 and 14 years. The excess body weight has been calculated according to national references from Ferrández et al.
Results:
Prevalence of excess body weight at age 14 years was significantly higher (P<.05) in males (29%) than in females (12.8%). BMI (kg/m2) was significantly higher (P<.05) for both sexes in every age period, except for birth and age 1 year, in those patients with excess body weight at age 14, with respect to patients with normal nutritional status of the same age. Those groups with excess body weight at age 14 showed a BMI (Z-score) reaching overweight or obesity levels at age 4, and progressively increasing.
Conclusions:
Excess body weight probably starts at early stages in life, when dietary habits of the child depends almost exclusively on family habits, and may be aggravated during school attendance. Finally, a disproportionate weight increase occurs in adolescence that is probably related to unhealthy dietary habits and way of life.
