Health disparities continue to report in DEIS schools: Irish COSI Round 6 study

Abstract Background Previous reports have identified clear differences in the prevalence of overweight and obesity among children living with disadvantaged compared to those living in advantaged circumstances. Childhood obesity is influenced by factors in the home environment, including lifestyle behaviours and socio-economic status. The Childhood Obesity Surveillance Initiative (COSI) family survey provides insights into these factors, particularly in children that attend disadvantaged (DEIS) and non-disadvantaged (non-DEIS) schools. Aim This study aims to compare various demographic and socioeconomic factors within the home environment of primary school children across DEIS and non-DEIS schools in Ireland, elucidating the differences in their performance with implications for health policy. Methods Parents of 1st and 2nd class children (mean age 7) from 121 sentinel schools invited to participate in the family survey, returned it by post or online using Lime Survey. Ethical approval was secured for COSI R6, with consent from families. Data on demographics, diet, transportation, activities, and clinical characteristics of children in Ireland were collected, anonymised and analysed in SPSS, comparing children from DEIS (n = 147) and non-DEIS (n = 1014) schools. Results Around 88% of respondents of returned surveys included in the study (n = 1161) were mothers. Significant disparity in families with diabetes diagnosis or treatment observed between DEIS and non-DEIS schools (10.6% vs. 5.4%, p = 0.016). Breastfeeding rates were higher in non-DEIS schools (57.0% vs. 46.9%, p = 0.015). Children consuming at least 3 portions of fruits and vegetables daily were also higher in non-DEIS schools (58.9% vs. 46.0%, p < 0.001). More children in non-DEIS schools engaged in physical activities outside of school hours (93.7% vs. 74.5%, p < 0.001). Conclusions The findings underscore the significant socioeconomic disparities between families whose children attend DEIS and non-DEIS schools in Ireland. Key messages • Irish COSI R6 reveals disparities in health-related factors between disadvantaged and advantaged schools. • Targeted interventions and policies are necessary to address factors influencing child health.
