“…The findings showed that the mean HRQoL score of Korean adults aged 30-80 years with DM was 0.91, which is similar to the quality of life of people with chronic diseases, such as hypertension and chronic liver disease [26,27], as well as in general populations [28]. The KNHANES IV and V collected data from 2007 to 2012 and reported a mean HRQoL score of 0.90 in Koreans aged over 50 years [29]. In contrast, the mean HRQoL score in the current study was higher than that reported in previous studies of people with dementia [28] or cancer [30,31].…”

Diabetes mellitus (DM) as a chronic disease is a major public health problem worldwide. It is important to improve the quality of life of people with DM, especially health-related aspects, which should be monitored and managed as part of diabetes management. Accordingly, this study investigated health-related quality of life (HRQoL) and identified predictors of HRQoL in Korean adults with DM using the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII) 2016–2018. This was a cross-sectional study with a stratified multistage probability sampling design that collected data from 1228 participants aged 30–80 years diagnosed with DM. HRQoL was measured using the Euro Quality of Life Five Dimension (EQ-5D) questionnaire. Analyses consisted of one-way analysis of variance, t-tests, chi-squared tests, and general linear regression analyses with complex sampling designs. Results demonstrated that low HRQoL was associated with older age (β = −0.002, 95% CI: −0.003 to −0.001), having elementary school education or less (β = −0.037, 95% CI: −0.061 to −0.014), being unmarried (β = −0.060, 95% CI: −0.078 to −0.040), poor subjective health status (β = −0.074, 95% CI: −0.094 to −0.055), perceived high stress (β = −0.047, 95% CI: −0.066 to −0.028), limited activity (β = −0.105, 95% CI: −0.131 to −0.079), being overweight (β = −0.021, 95% CI: −0.038 to −0.002), or obese (β = −0.016, 95% CI: −0.032 to −0.001), and three or more comorbidities (β = −0.044, 95% CI: −0.085 to −0.001). Comprehensive health care programs to manage these predictors should be provided to improve health-related quality of life of patients with DM.

“…However, only medical staff can judge health through examination, and in middle-aged and elderly people, it is not appropriate to define health as merely the presence or absence of disease, because a person who declares to healthy may have a chronic disease. Thus, we defined healthy participants using the EuroQol 5-Dimension Questionnaire (EQ-5D), a self-reported questionnaire about daily activities and social activities, which is a standardized measure of health status developed by the EuroQol Group to provide a simple, generic measure of health for clinical and economic appraisal [12]. The EQ-5D measured health perceptions and consist of a descriptive system with five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression).…”

Background: We investigated population-based data on grip strength, analyzed for demographic factors, and proposed a formula to estimate grip strength that could be generalized to a population with different anthropometric and background characteristics. Methods: This study used a complex, stratified, multistage probability cluster survey with a representative sample of the population. Select household Korean participants (n = 6577) over age 10 who were able to perform daily tasks without issue were included. Grip strength was measured in both hands, alternately, three times using a digital grip strength dynamometer. Results: There was a curvilinear relationship between grip strength and age, and grip strength was higher in males than females (p = 0.001). Hand preference significantly affected grip strength (p = 0.001). Weight and height were positively correlated with strength in both hands (p = 0.001), but waist circumference was negatively correlated with strength in both hands (p = 0.001). The intensity of occupational labor did significantly affect grip strength in both hands (p = 0.001). The formulas for estimating grip strength of each hand are presented as main results. Conclusions: To determine normative data on grip strength, we may consider factors such as occupations with different physical demands, underlying medical conditions, anthropometric characteristics, and unmodifiable factors such as age and sex.

Objectives/aimsWith the Euro-Qol-5 dimension (EQ-5D) system, we investigated the relationship between the number of remaining teeth and QoL using data from the Korean National Health and Nutrition Examination Survey (KNHANES), 2010–2012. A total of 17,417 participants, more than 19 years old, were finally included in this study (men = 7394 and women = 10,023). Through this study, we have discovered that the remaining teeth affect overall health and that the fewer number of them may indicate a lower quality of life, as well.The quality of life according to the number of remaining teeth was assessed among Koreans using the Euro-Qol-5 dimension (EQ-5D) system.MethodThe Euro-Qol-5 dimension (EQ-5D) system was used to measure the health-related QoL. Its five dimensions included mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The respondents were asked to choose one of the followings: G 1, no problems; G 2, some problems; and G 3, problematic, to best describe their health status for the five dimensions. Then, we assigned low QoL to G2 + G3 and high QoL to G1.We used age, gender, economic income, educational level, residence, and marital status for the demographic variables and, drinking, smoking, exercise, BMI, and metabolic syndrome for health behaviors. Multiple logistic regression analysis was performed to examine the odds ratios (ORs) and confidence intervals (CIs) for the high QoL (G1) on the five categories of EQ-5D according to the number of remaining teeth. On the basis of the 0–15 remaining teeth group, we drew a comparison of the QoL between the 16–20 and 21–28 remaining teeth groups.ResultsSubjects with 21–28 remaining teeth had higher QoL scores and had higher ORs of high QoL, especially for mobility (OR = 1.256, 95% CI = 1.056–1.495), self-care (OR = 1.441, 95% CI = 1.096–1.894), and usual activities (OR = 1.241, 95% CI = 1.022–1.508, respectively), than those with 0–15 remaining teeth after adjusting for age, sex, body mass index, smoking, drinking, exercise, income, education, and metabolic syndrome.ORs from the high QoL had the tendency to increase as the number of remaining teeth increased (all p for trend < 0.05). However, there was no relationship between the number of remaining teeth and QoL in the pain/discomfort and anxiety/depression dimensions.ConclusionThe number of remaining teeth was associated with QoL, and subjects who had more teeth obtained higher QoL scores. The subjects in the high QoL group were especially associated with the components of EQ-5D such as mobility, self-care, and daily living.
