: Hemodialysis patients face significant physical and psychological challenges, including diminished quality of life and reduced social support. This study aimed to assess the levels of social support and quality of life in hemodialysis patients and identify the sociodemographic and dialysis-related factors influencing these outcomes. : This study included 115 hemodialysis patients and 107 healthy controls. Social support was measured using the Modified Social Support Survey (MSSS) and its abbreviated version (MSSS-5). Quality of life was assessed using the WHOQOL-BREF questionnaire. Demographic variables (age, sex, education, marital status) and dialysis-related factors (session duration, Kt/V, vascular access type, and urea reduction ratio) were analyzed to determine their effects on social support and quality of life. : Hemodialysis patients reported significantly lower scores in the Physical Health and Psychological Health domains of the WHOQOL-BREF compared to healthy controls. Males on hemodialysis scored lower than the controls in the Physical Health, Psychological Health, and Environment domains of the WHOQOL-BREF and the Affectionate Support and Positive Social Interaction subscales of MSSS. Conversely, hemodialysis females reported higher scores for Tangible Support, Emotional/Informational Support, and Affectionate Support. Longer dialysis sessions negatively impacted the Social Relationships domain. Married hemodialysis patients had higher Emotional/Informational Support and Affectionate Support scores. : Hemodialysis patients experience diminished physical and psychological quality of life, particularly males. Social support, especially emotional and informational support, is crucial for hemodialysis patients, with marital status playing a key role. Addressing these psychosocial factors may improve outcomes for hemodialysis patients.
