Insights
Early identification of childhood obesity is crucial. This study found rapid weight gain after 6 months signals obesity risk, with paternal obesity and sibling obesity as key factors.
Area of Science:
- Pediatrics
- Public Health
- Childhood Obesity Research
Background:
- Childhood obesity is a growing global health concern.
- Identifying early indicators and risk factors is vital for intervention.
Purpose of the Study:
- To determine early signs of obesity trends in children aged 0-6 years.
- To investigate the influence of various factors on childhood obesity development.
Main Methods:
- Longitudinal follow-up of 102 children from birth to 6 years.
- Annual anthropometric measurements (weight, height, BMI, growth velocity).
- Recording and comparison of family history and lifestyle variables.
Main Results:
- Gender did not significantly affect obesity trends.
- Rapid weight gain velocity after 6 months was the earliest obesity indicator.
- Obesity indicators (BMI) appeared at 6 months (girls) and 1 year (boys).
- Obese children showed higher height after 4 years.
- Paternal obesity and obese siblings were significant risk factors.
Conclusions:
- Six months is a critical period for assessing obesity development in infants.
- Obesity prevention efforts should commence around 6 months of age.
Abstract:
The study was planned to determine identifiable starting points of a trend towards obesity and the influence of variables in preschool children aged 0 to 6 years. In this longitudinal follow-up study, 102 children were enrolled. Anthropometric measurements such as weight-height centiles (specific for gender and age group), weight-height growth velocities, and body mass indices were taken annually and compared within each group from birth to 6 years. Family history and lifestyle variables were also recorded and compared. Our study has shown that gender does not affect the trend towards obesity. In obese children, the earliest sign of a trend was the rapid increase of weight and weight gain velocity after 6 months. There were upward trends in the BMI values indicating obesity at 1 year of age in boys and at 6 months of age in girls. The height was higher in obese children than in non-obese ones after 4 years of age. Paternal obesity and having an obese sibling were significant risk factors for obesity. In conclusion, 6 months are considered to be the most critical periods for evaluating the development of obesity in childhood. The efforts for preventing obesity should be initiated at 6 months of age.
