Insights
Childhood obesity affects 37% of Portuguese children, with higher rates in boys. This study highlights significant differences in Body Mass Index (BMI) and body fat, underscoring the need for interventions.
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Childhood Obesity Research
Background:
- Childhood obesity is a global health issue impacting cardiovascular health and metabolic syndrome.
- Portugal faces a high prevalence, with 31.6% of children affected, necessitating urgent interventions.
- This research addresses the critical need to understand overweight and obesity patterns in Portuguese school children.
Purpose of the Study:
- To determine the prevalence of overweight and obesity in Portuguese school-aged children.
- To analyze sex and age-specific differences in childhood obesity indicators.
- To evaluate the impact of obesity on body composition and anthropometric parameters.
Main Methods:
- Anthropometric measurements (weight, height, skinfold thickness) were collected from 1564 children (ages 6-10).
- Body Mass Index (BMI) and body fat percentage were calculated using standardized methodologies.
- Statistical analysis was performed to identify significant differences in BMI and body fat across categories and sexes.
Main Results:
- Overall, 37% of the studied children were overweight or obese.
- Boys exhibited a higher prevalence (40.1%) compared to girls (33.9%).
- Significant differences (p≤0.001) in BMI and body fat percentage were observed across BMI categories and between sexes.
Conclusions:
- Childhood obesity significantly impacts body composition and anthropometric parameters in Portuguese children.
- A substantial proportion of school-aged children are overweight or obese, with boys being more affected.
- Findings emphasize the critical importance of implementing preventative and intervention strategies to combat childhood obesity.
Background:
Childhood obesity presents a significant public health concern globally, with implications for cardiovascular health and metabolic syndrome. In Portugal, approximately 31.6% of children are affected, highlighting the urgency for intervention strategies. This study aimed to assess the prevalence of overweight and obesity in Portuguese school-aged children, with a focus on sex and age differences.
Methods:
Anthropometric measurements were conducted on 1564 children aged 6-10 years, including weight, height, and skinfold thickness. Body Mass Index (BMI) and the percentage of body fat were calculated using established methods.
Results:
The results revealed significant differences in BMI (≤0.001) and body fat percentage (≤0.001) among different BMI categories, with a notable prevalence of overweight and obesity, particularly among boys. A total of 37% of the studied population is overweight or obese, among which 40.1% and 33.9% are boys and girls, respectively.
Conclusions:
This study highlights statistically significant differences in BMI and body fat percentage for both sexes in different BMI categories. A large proportion of the population is overweight or obese, with a greater prevalence in boys. In short, childhood obesity has a negative impact on body composition and is associated with significant differences in anthropometric parameters, emphasizing the importance of preventative and intervention strategies to address this health problem.
