This study was conducted to estimate the prevalence rates and to explore associated factors of sarcopenic obesity (SO) in 2,221 Koreans over 60 yr-of age from the Fourth Korea National Health and Nutrition Examination Survey (2009). Participants were assessed by dual energy X-ray absorptiometry. Appendicular skeletal muscle mass divided by body weight was used to define sarcopenia and waist circumference was used to define obesity. We estimated the prevalence rates of SO according to age-groups, sex and region. In addition, each group was compared by demographic characteristics, metabolic status, nutrition, and physical activity. The prevalence rates of SO were 6.1% (95% confidential interval [CI] = 6.1-6.2) for men and 7.3% (95% CI = 7.3-7.3) for women, respectively. SO was positively associated with no current working and the number of combined medical conditions. High serum insulin level was positively associated with SO, whereas vitamin D was negatively associated with SO in both men and women. In conclusion, the prevalence rates of SO are 6.1% in men and 7.3% in women. SO is associated with insulin resistance, inappropriate nutrition, and low physical activity.

OBJECTIVE: To determine the degree of disparity in unmet healthcare needs between people with disabilities and the general population in South Korea, and to analyze their perspective reasons. METHOD: Survey results of 9,744 subjects that participated in the 4th Korea National Health and Nutrition Examination Survey and 7,000 people that participated in the 2008 Survey of Disabled people were used in this population-based cross-sectional study. Unmet healthcare needs were identified as reporting experience during the last 12 months when there was a need to see a doctor, but were unable to get it. We assessed unmet healthcare needs by demographic variables, social variables and characteristics of disability. Chi-square test and logistic regression were used to determine which variables were related to unmet healthcare needs. RESULTS: A total of 22.1% of people with disabilities and 22.8% of the general population had unmet healthcare needs. However, brain impairment (25.3%) and physical impairment (25.2%) had more unmet healthcare needs than the general population and other disabilities. Unmet healthcare needs of people with disabilities was related to sex, age, self-perceived health, marital status, income, occupation and category of disability. Whereas the reasons for unmet healthcare needs in people with disabilities were lack of money (57.3%) and inaccessible transportation (12.8%), those for the general population were no available time (30.2%) and mild symptoms (23.8%). CONCLUSION: Brain and physical impairment cases with limitations to accessible transportation had the higher unmet healthcare needs. In addition, the reasons for people with these disabilities were more environmental than those of the general population.

OBJECTIVE: To investigate the accessibility of medical services for Korean people with spinal cord injury (SCI) compared to the control group (CG) and to evaluate significantly related factors. METHODS: A total of 363 community dwelling people with chronic SCI were enrolled and 1,089 age- and sex-matched subjects were randomly selected from the general population as the CG. Self-reported access to medical services was measured by asking "Have you experienced the need for a hospital visit in the last year but could not?". This was followed up by asking the reasons for not receiving services when medically necessary. Variables, including lack of finances, difficulties making medical appointments, and lack of transportation were evaluated for accessibility to medical services. RESULTS: Sixty subjects (16.5%) in the SCI group had difficulties receiving medical services due to a lack of accessibility, compared to 45 (4.1%) in the CG (p<0.001). Variables causing difficulties receiving medical services were lack of transportation (27 persons, 45%), lack of finances (24 persons, 40%), and difficulty scheduling hospital appointments (9 persons, 15%) in the SCI group. In the CG, availability (lack of available time) and acceptability (deciding not to visit the hospital due to mild symptoms) were the reasons for not receiving medical care. CONCLUSION: People with SCI experienced limited accessibility to medical services, which was due to environmental rather than personal factors compared to that in the CG. Therefore, development of social policies to reduce or remove environmental variables is necessary.
