Interviews were conducted with the participants to collect sociodemographic and lifestyle data.Multiple linear regressionwas performed to identify the predictors of HGS. The findings revealed that women and individuals from older age groups showed lower HGS, while being active during leisure time was associated with higher HGS.Interventions aimed at maintaining HGS levels in individuals should pay special consideration toaging and individuals who are physically inactive or insufficiently active during leisure time.
