Determination of Quality of Life of Individuals Before and After Bariatric Surgery: Prospective Study with 1 Year Follow-Up

Objective: This study was conducted to investigate the effect of bariatric surgery on quality of life. Methods: This study used a quantitative, descriptive, cross-sectional and prospective study design. This study was conducted between 1 January 2016 and 1 June 2017 at an university hospital in Turkey. The questionnaire form that developed by the researchers and the Short Form36 quality of life scale before bariatric surgery were applied to the individuals. Participants were evaluated with the same scale at 1 month, 3 months and 1 year after bariatric surgery. Results: The mean age of the individuals was 37.37 +/- 9.18.While the mean of body mass index was 48.18 +/- 5.8 kg/m(2) before bariatric surgery, it decreased to 27.18 +/- 3.21 kg/m(2) in one year after bariatric surgery. Simple linear regression analysis was given between the subscale of SF-36 and the descriptive characteristics of the participants according to the follow-up times and there was a moderate positive relationship between preoperative physical health and gender (beta = 0.450, p <0.05). In the lineer regression analyses, a statistically significant relationship was found between the body mass index in the 3rd month and the quality of life before bariatric surgery (beta=1.446, p<0.05), between pre - body mass index and quality of life in post - bariatric surgery in 1st month (beta=1,474, p<0.05), between body mass index in post - bariatric surgery in 1st month and quality of life in post - bariatric surgery in 1st month (beta = 2.173, p<0.05), between body mass index in post - bariatric surgery in 3rd month and quality of life in post - bariatric surgery in 1st year (beta = -0.955, p<0.05). Conclusion: It is obvious that the nurse's counseling role is very important in the long-term follow-up of patients, including improving the quality of life. Within 1 year, bariatric surgery found a positive effect on quality of life as a result of weight loss.
