Introduction: Perceived self-efficacy is closely related to an adequate quality of life en general well-being of people, but few studies have studied this relationship in people with hemophilia. Objective: To determine the degree of relationship between perceived self-efficacy for weight control and quality of life in people with and without hemophilia, comparing both variables in case-control groups. Methods: The sample made up, for convenience, of 40 participants, with two matched groups. The group of cases consisted of 20 males between 19 and 24 years of age (M = 19.50, SD = 1.47) with hemophilia type A. The control group consisted of 20 males who did not present hemophilia, matched in age and weight status, between the ages of 18 and 24 years of age (M= 19.59, SD= 1.44). Participants answered the “Self-efficacy for Weight Control” questionnaire and the World Health Organization Quality of Life Bref” questionnaire. Descriptive statistics where used to describe the factors of each instrument. Student's t-test was used to compare differences between the two groups. Results: Only the Daily physical activity dimension showed a statistical difference in the control group. According to the Pearson correlation, a positive correlation was found between the Scheduled physical activity, Daily physical activity and Physical health dimensions. Conclusions: It is concluded that physical exercise, weight control, nutritional counseling and psychological support are essential for the quality of life, especially for people with hemophilia, which complements medical treatment
