| خلاصه مقاله | Background: Hedonic hunger, which refers to reward-driven eating beyond physiological needs with a focus on palatable foods, has been proposed as one of the important causes of obesity in recent years. The present systematic review and meta-analysis summarize the existing evidence for the association between hedonic hunger and body mass index (BMI) in healthy children and adolescents.
Methods: Three PubMed, Web of Science, and Scopus databases were searched using keywords until August 2023. All English-language original observational studies in which the Power of Food Scale (PFS) was used to evaluate hedonic hunger in healthy subjects, were included. Quality assessment was done using the Joanna Briggs Institute checklist, and StataMP-17 software was used for the meta-analysis.
Results: After screenings, four cross-sectional studies with a total participant of 3773 were included. Three studies were cross-sectional, and one was a cohort study. Three studies examined both sexes, while one study was conducted only on girls. The results of the meta-analysis of the correlation coefficient showed a non-significant association between hedonic hunger and BMI (r=-0.03, 95% CI: -0.08, 0.03). Moreover, the meta-analysis result showed that the mean hedonic hunger was not significantly different between overweight/obesity and normal weight groups (SMD=0.01, 95% CI: -0.21, 0.22).
Conclusion: There was a non-significant association between hedonic hunger and BMI in children and adolescents. Considering the small number and the low quality of included studies, we need longitudinal design studies that consider the association between these two variables as a primary outcome for a more accurate conclusion. |
