Participation inequality in the National General Health Examination based on enterprise size

BackgroundHealth examinations are performed so that diseases can be identified and treated earlier. Several studies have evaluated the determinants of participation in health examinations including cancer screening, but few have evaluated the relationship between the size of the enterprise and their participation in Workers’ General Health Examinations (WGHE). The aim of the present study was to estimate the association of WGHE participation with the size of the enterprise and the type of policyholder.MethodsThe eligible population from 2006 through 2013 was extracted from the National Health Insurance Service (NHIS) database. The population size ranged from 14–17 million. After adjustment for age and gender, multiple logistic regression analysis was performed to estimate the odds ratios of participating in the WGHE (by age group) based on the type of policyholder (reference: public officers) and the size of the enterprise (reference: enterprise size ≥300 employees), respectively.ResultsWorkers employed at enterprises with <50 persons were less likely to participate in WGHEs than those employed at enterprises with ≥300 persons. After policyholders were stratified by type (non-office workers vs. public officers), a disparity in the WGHE participation rate was found between the different types of policyholders at enterprises with <50 employees (reference: those employed at enterprises with ≥300 employees); the odds ratios for subjects in their 40s and 50s were 0.2–0.3 for non-office workers vs. 0.8–2.0 for public officers.ConclusionWorkplace policyholders at small enterprises comprised a vulnerable group less likely to participate in WGHEs. Efforts should be made to raise the WGHE participation rate among the vulnerable employees belonging to small enterprises, as well as among their dependents.

Adverse pregnancy outcomes in healthcare workers: a Korean nationwide population-based study

PurposeTo assess female healthcare workers’ pregnancy complications and outcomes including abortion, fetal screening abnormalities, intrauterine growth retardation (IUGR), and preterm labor using nationwide population data and compare these results with those of the general population in Korea.MethodsKorean National Health Insurance (NHI) claim data was used. We choose 3 different reference groups for comparison: (1) dependents of employees insured by NHI, i.e. non-working women, (2) all insured employees, i.e. all working women, and (3) workers in the education division. To compare the groups, logistic regression was used for multivariate analysis after adjusting for age and income level.ResultsOverall, healthcare workers showed a higher adjusted OR (odds ratio) in almost all obstetrical consequences. Miscarriage, threatened abortion, preterm labor, fetal screening abnormalities, and IUGR showed a higher adjusted OR in the working group than in the non-working group. We also observed similar results in a comparison of both the working groups. Regarding workers in the education division, ORs for obstetrical outcomes were also high, except for preterm labor.ConclusionsHealth care workers have a higher risk of adverse pregnancy outcomes such as miscarriage, IUGR, and fetal screening abnormalities.

The current condition of the workers’ general health examination in South Korea: a retrospective study

BackgroundBusiness owners in the Republic of Korea must take part in the workers’ general health examination. However, there have been few formal analyses of the uptake of this examination by employees. In the present study, we examined the rates of participation in medical examinations according to age group, health insurance type, and enterprise size, and then compared these results with those of the national general health screening. Furthermore, we determined the distribution of patients with abnormal results for diabetes and hypertension, and outlined the significance and history of domestic health examinations.MethodsWe started by comparing participation rates extracted from the among health examination data of the National Health Insurance Service from 2006–2013 by sex, age, insurance type, and enterprise size of workplace health insurance beneficiaries (i.e., those whose insurance is provided by their workplace). In addition, we analyzed the prevalence rates of abnormal results for hypertension and diabetes, and explored the history and significance of health examinations in the Republic of Korea.ResultsThe overall participation rate in the primary health examination in 2006 was 56%, and this increased to 72% in 2013. However, the rates of the secondary screening did not increase much. Among workplace policyholders (i.e., those whose insurance is provided by their workplace), the participation rates of workers in enterprises with less than 50 employees were lower than were those in enterprises with 50 or more employees. Notably, the rates and odds ratios of patients with abnormal results for diabetes and hypertension were relatively high, particularly among those working in smaller enterprises.ConclusionsAlthough the workers’ general health examination has been replaced with the national general health screening, it remains necessary to ensure uniform health management services among all workers in the Republic of Korea. This can, in turn, promote occupational health and improve working conditions throughout the Republic of Korea.
