Abstract Introduction Sexual health is an integral component of quality of life, influenced by both biological and psychosocial factors. Obesity is a significant risk factor for sexual dysfunction, but appropriate medical interventions and lifestyle changes can significantly improve patients' sexual health and quality of life.Obesity has been a part of humanity's life for centuries. Historically, it was perceived as a symbol of prosperity, wealth, and high social status. As civilization progresses and develops, obesity has become increasingly visible and a health threat, which is why it is often referred to as an epidemic of the 20th and 21st centuries and a lifestyle disease. Objective The study evaluates the quality of life and sexual functioning in individuals with obesity undergoing bariatric treatment within the pilot KOS-BAR Programme (a pilot programme of comprehensive specialist care in preparation for bariatric surgery). The findings undeline the importance of integrated psychological and medical support. Methods The study included 131 participants (90 women – 68.7% and 41 men – 31.3%), aged 20 to 65 years (mean age: 41.5; SD = 10.9). The research was conducted between 2022 and 2023 among patients qualified for the KOS-BAR Programme. Data were collected through individual interviews and questionnaires assessing demographics, eating behaviours, weight history, diet, physical activity, mood (author-designed questionnaire), and quality of life (SWLS – Satisfaction with Life Scale), as well as sexual satisfaction (KSS – Sexual Satisfaction Questionnaire). Results The study included individuals in the preparatory phase for bariatric surgery. A total of 76.3% of participants presented with class III obesity (BMI ≥ 40; mean weight 134.7 kg), while 23.7% had class II obesity (BMI 35.0–39.9; mean weight 108 kg). Quality of life (SWLS) scores for the most of respondents were within the average range, irrespective of obesity class (64.5% in class II obesity and 60% in class III obesity). Regarding sexual satisfaction (KSS), only 4.6% of participants reported a high level of sexual satisfaction. A low level was noted in 46.6% while 48.9% of participants were within the average level, with no statistically significant differences between BMI categories or genders. More than half of the respondents (53.4%) considered their sex life satisfactory; 74% reported not feeling sexually attractive, and 35.1% expressed concerns about their role as a sexual partner. A moderate positive correlation was found between quality of life and sexual satisfaction (r = 0.5; p 0.001), which was stronger associations observed among men (r = 0.727; p 0.001) than among women (r = 0.409; p 0.001). No significant correlations were identified between body weight and level of sexual satisfaction. Conclusions Among individuals with class II and class III obesity, a high levels of sexual satisfaction are uncommon. A comprehensive therapeutic approach that integrates weight reduction and psychological support - including psychodietetics and psychosexology intervantions may contribute to improve the sexual quality of life in people living with obesity.
