Background The relationship between weight change and quality of life remains controversial. This study aimed to investigate whether changes in body weight among participants in different baseline body mass index categories are associated with physical and mental health functioning.
Methods We conducted an analysis involving 5,106 adults who participated in the Korean Genome and Epidemiology Study, a cohort comprising Korean adults aged 40 to 69 years. We categorized participants into three groups based on body weight change, and physical and mental health were assessed using the 12-Item Short-Form Health Survey in year 4. We employed logistic regression analysis to assess the association between body weight change and poor functioning at year 4. We also utilized a generalized estimating equation to determine the relationship between weight changes and mental component summary (MCS) scores over the study period for each weight group.
Results Weight gain in both the normal weight (odds ratio [OR], 1.88; 95% confidence interval [CI], 1.13–3.11; P=0.01) and overweight groups (OR, 1.75; 95% CI, 1.05–2.91; P=0.03) was associated with poor MCS. Normal weight weight-losers were associated with a greater increase (2.69 points; 95% CI, 0.50–4.88) in MCS compared to weightmaintainers. Significant differences in mean MCS were observed for overweight weight-losers, obese weight-gainers, and underweight weight-gainers when compared to weight maintainers in each respective weight group.
Conclusion Different patterns of relationships between weight change and mental health-related quality of life were observed. Hence, it is crucial to focus on the mental health of middle-aged and older adults when assessing body weight changes.

Background : According to different characteristics of health dimensions and its consisting item contents, valid and useful health status assessment tool for the elderly is rare. Because of the continuous increase in elderly population with functional disability in Korea, the need for a valid Korean health status assessment tool for the elderly is growing. Therefore, we have attempted to develop a Korean Health Status Measure for the Elderly in this study.
Methods : We gathered important health related items from 671 individuals aged 60 years and over to form item pool with interview. Then we classified all items into representative items according to its meaning with the experts in geriatrics. With these representative items we constructed a preliminary questionnaire. After wards we performed a pilot study for evaluating understandability, accessibility, item analysis, reliability and for detecting other modifiable limitations. After completing the pilot study we finally developed the Korean Health Status Measure for the Elderly (KoHSME V1.0)
Results : The number of collected health related items were 2,500 in the item pool. After classification of items in the pool, 40 representative items were selected for constructing preliminary version of the KoHSME. And we added 3 items of ‘general health perception’ dimension to 40 common representative items to construct a preliminary version of the KoHSME. It took an average of 18.8 minutes to complete the preliminary questionnaire by the elderly in the pilot study. Most responders (90.9%) thought the questionnaire was not difficult to understand. After the pilot study we added 2 items (wearing clothes, pain frequency) and omitted 1 item (eating). Finally, the KoHSME V1.0 questionnaire consisted of 44 items and 6 domains such as physical function, emotional function, social function, pain, sexual function, and general health perception. All items were Likert scale except pain intensity item, which was visual analogue scale.
Conclusion : The KoHSME V1.0 to assess health status and quality of life for the Korean elderly was developed. We think the KoHSME V1.0 is a reliable instrument for assessing health related to quality of life in the elderly. After documenting the validity, the KoHSME V1.0 can be a useful tool for comprehensive assessment of health status in the eelderly and for the medical outcome study.
Background : Weight loss in obese patients has been shown to decrease plasma lipid level and high blood pressure, to improve glycemic control in diabetic patients and to decrease cardiovascular risk in obese patients. But, study for association of weight loss and Health-related Quality of Life is not well known yet worldwide. This study was to determine whether weight loss would associate with improvements on Health-Related Quality of Life.
Methods : Participants was recruited in 48 obese patient visiting obesity clinic of Family Medicine of Sungkyunkwan University Hospital. 27 patients who answered mailed questionnaire was analyzed. Health-Related quality of life was measured by Catholic Medical Center Health Survey(CMCHS) V 1.0. Questionnaire included not only Health Related Quality of Life but also alcohol habit, exercise, smoking, marital status, economic status, education.
Results : In multiple regression analysis, weight loss is statistically significant differences on satisfaction, vitality, physical function, social function, role limitation, general health dimensions of CMCHS.
Conclusion : The results of this study demonstrate that weight loss on obese patients may be associated with an improvement in Health-Related Quality of Life.
