| خلاصه مقاله | Introduction: Hedonic hunger, characterized by reward-driven eating focused on palatable foods beyond physiological needs, has been suggested as a significant contributor to overweight and obesity in recent years. The Power of Food Scale (PFS) is the main tool for assessing hedonic hunger. As far as we know, no systematic review/meta-analysis has been done to investigate the odds of overweight/obesity associated with hedonic hunger. Therefore, this systematic review and meta-analysis aim to determine whether hedonic hunger increases the odds of being overweight/ obese.
Search Strategy: We conducted a comprehensive search on PubMed, Web of Science, and Scopus until January 19, 2023, using relevant keywords such as ‘hedonic eating,’ ‘hedonic feeding,’ ‘hedonic hunger,’ ‘hedonic appetite,’ ‘obesity,’ ‘overweight,’ ‘body weight,’ ‘anthropometry,’ ‘body mass index,’ and ‘BMI.’ All English-language original observational studies conducted on healthy adult subjects, which used the power of food scale (PFS) to evaluate hedonic hunger were included. Data extraction followed a predefined form, and quality assessment was performed using the Joanna Briggs Institute checklist. Meta-analysis was conducted using StataMP-17 software with the Random Effect method.
Results: Results: From electronic database searches, a total of 1294 articles were identified, along with one study found through manual reference searching. After screening, two cross-sectional observational studies involving 1286 participants were included in the systematic review and meta-analysis. Both studies were cross-sectional and included participants of both sexes. The meta-analysis revealed that hedonic hunger increased the odds of overweight/obesity by 68% (OR=1.68, 95% CI: 1.16, 2.21).
Conclusion: Hedonic hunger may increase the odds of being overweight/obese. Given the limited number and low quality of included studies, additional longitudinal research is necessary for a more precise conclusion. |
