Insights
Routine school health screenings in the Republic of Ireland can effectively estimate childhood overweight and obesity prevalence. This study found rates comparable to Western nations, highlighting the need for standardized definitions.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Investigates feasibility of using existing primary school health screening data.
- Focuses on estimating childhood overweight and obesity prevalence in a rural Republic of Ireland (ROI) setting.
Purpose of the Study:
- To assess the utility of routine health data for childhood obesity surveillance.
- To determine overweight and obesity prevalence in young children in North-West ROI.
Main Methods:
- Retrospective cohort study of senior infants (2001/2002) in County Leitrim and Cavan.
- Utilized paper-based health records, calculating Body Mass Index (BMI).
- Applied International Obesity Task Force (IOTF) and UK growth standards for prevalence estimation.
Main Results:
- Identified 361 children; 91% had available weight and height data.
- IOTF standards: 25% (boys) and 26% (girls) overweight/obese.
- UK standards: 34% (boys) and 23% (girls) overweight/obese.
Conclusions:
- Routine school health programs can generate reliable childhood obesity prevalence data in ROI.
- Prevalence rates are comparable to other Western countries.
- Further research is needed for a universally accepted definition of childhood overweight and obesity.
Background:
This retrospective cohort study investigates the feasibility of using established methods and routinely generated data from the statutory primary school health-screening programme to estimate prevalence rates for childhood overweight and obesity in children from a rural area in the Republic of Ireland (ROI).
Method:
Paper-based records in the primary school health service for County Leitrim and parts of County Cavan in north-west of ROI were hand searched to identify children attending senior infant classes during academic year 2001/2002. Electronic calculation of body mass index (BMI) and age at examination was carried out. Application of age- and sex-specific cut-off points from International Obesity Task Force (IOTF) and United Kingdom (UK) standard definitions for childhood overweight and obesity was used to determine age- and sex-specific prevalence rates for childhood overweight and obesity.
Results:
The eligible cohort was almost completely identified and consisted of 361 children. Weight and height measurements were available on 328 (91%) children aged between 4.22 and 7.92 years. IOTF standard application gave prevalence rates of 25% for obesity and overweight in boys and 26% in girls. With the UK growth standard, this increased to 34% in boys and reduced to 23% in girls.
Conclusion:
It is feasible to generate prevalence rates for childhood overweight and obesity from data routinely obtained through the statutory school health-screening programme in ROI. This study suggests levels of childhood overweight and obesity comparable to other Western societies. Further research on developing a universally accepted standard definition of childhood overweight and obesity is required.

Observational Studies
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One example of...
Study Designs in Epidemiology
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
Prevalence and Incidence
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...
