Insights
Childhood obesity is a growing concern. In Northern Ireland, 16% of 13–14 year olds are overweight, with a notable difference in weight-reducing diet uptake between genders.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Background:
- Rising trends in childhood overweight and obesity globally.
- Lack of recent data specific to Northern Ireland.
- Integration of anthropometric measurements into an existing international study.
Purpose of the Study:
- To determine the prevalence of overweight and obesity in children in Northern Ireland.
- To apply recent international guidelines for defining pediatric overweight and obesity.
- To investigate dietary behaviors among obese children.
Main Methods:
- Cross-sectional study involving 26 schools in Northern Ireland.
- Data collection included questionnaires and anthropometric measurements (height and weight).
- Sampled 2484 children aged 13–14 years, with 2307 weighed and measured.
Main Results:
- Prevalence of overweight was 16% in boys and 16% in girls.
- Prevalence of obesity was 4% in boys and 2% in girls.
- 15% of obese boys and 38% of obese girls reported being on weight-reducing diets.
Conclusions:
- 16% of Northern Irish children aged 13–14 are overweight, aligning with international guidelines.
- Obesity prevalence in this age group is significant, with differing dietary intervention rates between genders.
- Findings highlight the need for targeted public health strategies addressing pediatric obesity in Northern Ireland.
Unlabelled:
Concern has been expressed in recent years over the rising trends in overweight and obesity, particularly in children in developed countries. No recent data were available for Northern Ireland, therefore measurements of height and weight were included in a study in Northern Ireland originally designed as part of an international study to estimate the prevalence of symptoms of asthma and atopy in childhood. Twenty-six schools across the province were sampled. 2484 children aged mainly 13 and 14 y completed questionnaires, and 2307 were weighed and measured. Using recently proposed international guidelines on defining overweight and obesity in children the prevalence of overweight in boys was 16%, with 4% being obese. In girls 16% were also overweight and 2% were obese. This concurs with figures for English and Scottish schoolchildren up to 12 y of age from 1994. Less than one-sixth of obese boys but more than one-third of obese girls were on weight-reducing diets (the majority self-prescribed), reflecting differing attitudes towards excess weight.
Conclusion:
In line with figures in younger children from England and Scotland this study shows that 16% of boys and girls from Northern Ireland are classed as overweight using recent international guidelines. Only 15% of obese boys compared with 38% of obese girls stated that they were on weight-reducing diets.
