Insights
Prevalence of overweight and obesity in Bahraini preschoolers varies by age and sex. Using World Health Organization (WHO) cut-offs significantly increases detected rates compared to International Obesity Task Force (IOTF) indicators.
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Childhood Obesity Research
Background:
- Childhood overweight and obesity are significant global health concerns.
- Accurate prevalence data is crucial for effective public health interventions.
- Different growth charts and cut-off values can impact reported prevalence rates.
Purpose of the Study:
- To determine the prevalence of overweight and obesity in Bahraini preschoolers aged 2-5 years.
- To compare prevalence estimates using World Health Organization (WHO) and International Obesity Task Force (IOTF) cut-off values.
- To highlight the importance of standardized reference values in pediatric obesity assessment.
Main Methods:
- Cross-sectional study involving 354 males and 344 females aged 2-5 years.
- Measurement of weight and height to calculate Body Mass Index (BMI).
- Application of WHO and IOTF criteria for defining overweight and obesity.
Main Results:
- Using WHO cut-offs, overweight prevalence was 12.3% and obesity 8.4% in females (2-<4 years).
- Overweight prevalence was 8.4% and obesity 7.2% in males (4-<6 years) using WHO cut-offs.
- WHO criteria yielded approximately a 2-fold increase in overweight and obesity compared to IOTF indicators across most age groups.
Conclusions:
- Prevalence of overweight and obesity in Bahraini preschoolers differs based on age and sex.
- Significant discrepancies exist between WHO and IOTF cut-off values, impacting prevalence estimates.
- Standardization of reference values is essential for consistent and comparable childhood obesity surveillance and programming.
Abstract:
A cross-sectional study was carried out on Bahraini preschoolers aged 2-5 years (354 males and 344 females) to determine the prevalence of overweight and obesity using the World Health Organization and the International Obesity Task Force cut-off values. Weight and height were recorded and body mass index (BMI) was calculated to determine the proportion of overweight and obesity. Using the World Health Organization percentile cut-off values, overweight (12.3%) and obesity (8.4%) was higher in females between 2 and <4 years of age whereas, the proportion of both overweight (8.4%) and obesity (7.2%) were higher in males between 4 and <6 years of age. Relative to the International Obesity Task Force indicators, the World Health Organization cut-off values produced nearly a 2-fold increase in both overweight and obesity at most ages. It is therefore important to ensure that the same cut-off reference values are used to define overweight and obesity particularly in preschoolers. Shifting to the new World Health Organization child growth standards may have important implications for child health programmes.
