Job analysis of vaccination health workers at public health centers and sub-centers.

OBJECTIVE: To analyze duties, tasks, and task elements of health workers in charge of vaccination at public health centers in South Korea. DESIGN: Descriptive study using a survey. SAMPLE: Health workers in charge of vaccination for more than 1 year at 254 public health centers in South Korea. Of 631 health workers, 401 responded to the questionnaire, and 379 responses were included in the analysis after excluding 22 incomplete responses. MEASUREMENTS: The Developing A Curriculum (DACUM) workshop was conducted to identify the frequency, importance, and difficulty of duties, tasks, and task elements. RESULTS: Four duties (vaccination promotion, vaccination administration and symptom management, execution of vaccination, and vaccination education), 18 tasks, and 81 task elements were identified. "Execution of vaccination" exhibited the highest determinant coefficient. "Implementing the budget" exhibited the highest determinant coefficient among tasks, and "dealing with an emergency in the case of adverse events" exhibited the highest determinant coefficient among task elements. CONCLUSIONS: Duty, task, and task elements with high determinant coefficients have high educational needs. Education demands was higher for administrative work than for direct vaccination. Developing an educational curriculum based on DACUM results could contribute to the professional education of vaccine workers.

Korea Seroprevalence Study of Monitoring of SARS-COV-2 Antibody Retention and Transmission (K-SEROSMART): findings from national representative sample.

OBJECTIVES: We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea. METHODS: In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022. RESULTS: In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%. CONCLUSIONS: The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

Publication of the Korea-WHO Cooperation History - 70 Years of Working Together for Heath: World Health Organization and the Republic of Korea.

The World Health Organization (WHO) have been in collaborative efforts with the Republic of Korea in keeping of and for better health for all for the past decades. From the control of parasites to building of community health system in rural places, the works has now resulted in healthier Korea than ever, and has transformed the role of engaging as the world leader in contribution of health and development. Seventy years of independence, war, and poverty, transforming from a recipient country of official development assistance to a significant donor to the global society, we have emphasized the importance of international cooperation and the role of WHO in the past years in Korea and neighboring countries. Looking back of the past is meaningful to diagnose the present problems, and to foresee the future of our world.

Socioeconomic Indicators Associated with Initiation and Cessation of Smoking among Women in Seoul.

BACKGROUND: While smoking prevalence in Korean men has been decreasing, it is increasing in Korean women. Little is known about women's smoking inequalities in Korea. This study was conducted to investigate the association of socioeconomic indicators with the initiation and cessation of smoking among Korean women. METHODS: This was a cross-sectional study on 9,089 women aged 25-64 years from the 2008 Seoul Community Health Survey. The data on smoking and socioeconomic status were obtained through face-to-face interviews. Smoking initiation rate was defined as the proportion of the individuals who had started smoking at least one cigarette among all subjects. Smoking cessation rate was calculated by dividing the number of individuals who had quit smoking by the number of ever smokers. Education level, total family income and occupation were investigated as socioeconomic indicators. RESULTS: Education level was significantly associated with both initiation and cessation of smoking. Lower educated women had a higher likelihood of smoking initiation (odds ratio [OR], 1.72; 95% confidence interval [CI], 1.17 to 2.51) but lower likelihood of smoking cessation (OR, 0.38; 95% CI, 0.22 to 0.66) than higher educated women. Smoking initiation rate was higher in manual workers (OR, 1.65; 95% CI, 1.20 to 2.27) than in non-manual workers. However, there were no significant differences of both initiation and cessation of smoking according to total household income. CONCLUSION: This study shows that there are smoking inequalities among Korean women. It is thought that education level and occupation are important determinants of women's smoking status.
