Aims: We aimed to examine whether pain-inducing musculoskeletal disorders might explain the gender difference in the strength of the self-rated health (SRH)-mortality association. Methods: We pooled data from two National Health and Nutrition Examination Surveys (conducted in 1998 and 2001), which were linked to national mortality data of Korea using 13-digit unique personal identification numbers. There were 9,912 study participants, and 456 deaths were recorded (average length of follow-up=5.7 years). Using a checklist of chronic conditions, the prevalences of major pain-causing musculoskeletal disorders (arthritis, sciatica, and herniated intervertebral disc) were obtained. Results: The relative risk (RR) of mortality for the poor and very poor categories of SRH tended to be greater in men than in women. Compared with those without musculoskeletal disorders, the RR for those with musculoskeletal disorders was similar in men but lower in women. Women had a greater prevalence of musculoskeletal disorders than men, and women with musculoskeletal disorders reported poorer health than did men with these disorders. In individuals without major musculoskeletal disorders, the strength of the SRH-mortality association was reduced in men but increased in women. Similar patterns in RRs for SRH by gender were observed when sociodemographic characteristics (education and marital status), number of severe chronic illnesses, and health behaviors (cigarette smoking, alcohol consumption, and regular physical exercise) were additionally adjusted for. Conclusions: Nonfatal musculoskeletal disorders may explain gender differences in the SRH-mortality association. Larger prospective studies in different cultural settings may help advance our understanding of the role of pain and pain-inducing musculoskeletal disorders in explaining gender differences in the SRH-mortality association.

This study investigated the German experience in the transition to a unified health care system and suggests the following implications for Korea. First, Germany could have made use of the unification process better if there had been a good road map. Therefore Korea must develop a well prepared road map that considers all possible situations. Second, Germany saw an opportunity for the improvement of the health care system in the early stage of unification but could not take advantage of it because the situation changed dramatically and they had not sufficiently prepared for it. Korea should take into account the opportunity for improvement of the present health care system, such as the roles of public health and traditional medicine. Thirdly, the conditions f North Korea seem to be far worse than those of former East Germany and also worse than even those of other transition countries. Therefore Korea should design a long-term road map taking as many variables into account as possible, including the different rigid way of thinking and the interrelationship among the social sectors. Fourthly, during the German reunification unexpected factors changed the direction of the events. Korea should have a separate plan for the unexpected factors.

Objectives: This study explored gender- and age-specific contributions of explanatory factors to the relationship between self-rated health (SRH) and all-cause mortality. Methods: We used mortality follow-up data from 1998 and 2001 National Health and Nutrition Examination Surveys of South Korea (n = 9,663). Explanatory factors included baseline health status, socioeconomic status, health behaviors, clinical risk factors, psychosocial factors, and family medical history. Results: The ability of explanatory factors to explain the SRH-mortality relationship differed with age. For those aged 30-64, most excess hazards were explained by all explanatory factors. However, a large part of the mortality differentials by SRH remained unexplained among elderly samples. Conclusions: A wide range of health-related factors could explain the SRH-mortality association in younger population but not in older population. Factors to explain a large part of mortality differentials by SRH among older population should be identified. © 2010 Swiss School of Public Health. Source

Issues regarding healthcare disparity continue to increase in connection with access to quality care for acute myocardial infarction (AMI), even though the case-fatality rate (CFR) continues to decrease.We explored regional variation in AMI CFRs and examined whether the variation was due to disparities in access to quality medical services for AMI patients.A dataset was constructed from the Korea National Health Insurance Claims Database to conduct a retrospective cohort study of 95,616 patients who were admitted to a hospital in Korea from 2003 to 2007 with AMI. Each patient was followed in the claims database for information about treatment after admission or death.The procedure rate decreased as the region went "down" from Seoul to the county level, whereas the AMI CFR increased as the county level as a function of proximity to the county level (30-day AMI CFRs: Seoul, 16.4%; metropolitan areas, 16.2%, cities; 18.8%, counties, 39.4%). Even after adjusting for covariates, an identical regional variation in the odds of patients receiving treatment services and dying was identified. After adjusting for invasive and medical management variables in addition to earlier covariates, the death risk in the counties remained statistically significantly higher than in Seoul; however, the degree of the difference decreased greatly and the significant differences in metropolitan areas and cities disappeared.Policy interventions are needed to increase access to quality AMI care in county-level local areas because regional differences in the AMI CFR are likely caused by differences in the performance of medical and invasive management among the regions of Korea. Additionally, a public education program to increase the awareness of early symptoms and the necessity of visiting the hospital early should be established as the first priority to improve the outcome of AMI patents, especially in county-level local areas.

Objective: We examined the risk of cardiovascular disease, stroke, ischaemic heart disease, and diabetes with the metabolic syndrome according to the new harmonised definition and its components using a national longitudinal data set from an Asian population. Methods: Data of 9791 men and women aged 20+ from 1998 and 2001 Korea National Health and Nutrition Examination Surveys were individually linked to national hospitalisation and mortality data using unique personal identification numbers. During a 5.8-year follow-up through 2005, 288 incident cardiovascular events (184 strokes and 122 cases of ischaemic heart disease) and 85 new diabetes cases have been detected. Results: Men and women with the metabolic syndrome had 48%, 39%, 64%, and 127% greater risks of cardiovascular disease, stroke, ischaemic heart disease, and diabetes, respectively, than those without the metabolic syndrome. The increased risks of cardiovascular disease, ischaemic heart disease, and diabetes remained significant after adjusting for health behaviours, bio-clinical factors, family history, and socio-demographic factors. Analysis results on population attributable risks showed that about a quarter of total diabetes occurrence and more than 10% of cardiovascular disease was attributable to the metabolic syndrome. The number of metabolic syndrome components was linearly associated with risks of outcomes. High blood pressure was significantly associated with all four outcomes while hypertriglyceridemia and hyperglycemia were also important for ischaemic heart disease and diabetes, respectively. Conclusions: Reduction of metabolic risk factors is necessary in South Korea to lower the burden of associated diseases, especially ever-increasing ischaemic heart disease and diabetes. © 2010 Elsevier Ireland Ltd.
