| خلاصه مقاله | Introduction: Hedonic eating, reward-driven eating rather than out of biological needs, has been proposed as one of the important causes of overweight and obesity in recent years. The present systematic review and meta-analysis aim to compare hedonic hunger between normal weight and overweight/obese adults.
Methods: We conducted a comprehensive search on PubMed, Web of Science, and Scopus until January 19, 2023, using relevant keywords. All English-language original observational studies conducted on healthy adult subjects that 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-effects method.
Results: From electronic database searches, a total of 1,294 articles were identified, along with one study found through manual reference searching. Five cross-sectional studies with a total of 2,761 participants were included after screenings. All studies included both sexes. Two studies included only university students, and three studies were conducted on adults. The results of the random-effect meta-analysis (I2=22.15%, Q=5.77, P=0.33) showed that the mean hedonic hunger was significantly higher in individuals with overweight/obesity (SMD=0.33 [0.23, 0.43]).
Conclusion: Hedonic hunger may be higher in overweight/obese adults than in those of normal weight. Given the limited number and low quality of included studies, additional longitudinal research is necessary for a more precise conclusion. |
