Introdution: Health-Related Quality of Life (HRQoL) is a multidimensional concept encompassing aspects of quality of life that directly or indirectly relate to health, such as physical, psychological, and social well-being.
The interplay between socioeconomic factors, like family earnings and weight status impacts children’s HRQoL, highlighting the importance of addressing these factors to promote health equity from an early age.
Methods: This observational cross-sectional study analyzed data from the 6th WHO European Childhood Obesity Surveillance Initiative, the COVID study in Portugal, targeting primary school-age children. BMI was calculated using WHO reference growth charts for children, and data on children's HRQoL and family perceived wealth was obtained through a family form, reporting data during the COVID-19 pandemic (March 2020-June 2022). HRQoL was assessed using the KIDSCREEN-10 parent report, with Rasch scores calculated and transformed into T-scores. Higher values indicate higher levels of HRQoL.
Family perceived wealth reflects how easily a family meets monthly expenses using their earnings. It is categorized as “low” (combining the answers “we have trouble meeting the end of the month with our earnings” and “we barely meet the end of the month with our earnings”), “medium” (“we meet the end of the month with their own earnings without serious problems”), and “high” (“we easily met the end of the month with their own earnings”).
Results: Among the 3279 children analysed, 12.0% were classified as having obesity, with a higher proportion of boys (51.8%) than girls (48.2%).
After adjusting for sex and age, the linear regression coefficients showed that family perceived wealth was positively associated with HRQoL in both groups (without obesity: medium compared with low 2.548, 95% CI: 1.398;3.699, p<0.001 and high compared with low perceived health 4.240, 95% CI: 2.953;5.527, p<0.001; with obesity: medium compared with low 3.671, 95% CI: 0.810;6.532, p=0.012 and high compared with low perceived health 3.850, 95% CI: 0.516;7.184, p=0.024).
General linear regression also showed that family perceived wealth demonstrates a clear gradient effect in both groups. The differences in age and sex-adjusted mean scores between the lowest and the medium and higher perceived wealth levels were statistically significant for HRQoL scores (47.64 for high, p<0.001, 45.93 for medium, p=0.003, and 43.38, p<0.001, for low in children without obesity; 48.04, 47.85, and 44.19 respectively in children with obesity, with p=0.038 for the lowest category).
Conclusion: Findings suggest that family perceived family wealth significantly influences children's HRQoL, regardless of BMI. The relationships between this factor and HRQoL emphasize the need for multifaceted interventions that address both family socioeconomic circumstances and weight status to improve children's health and well-being.
