Objectives A stable follow-up participation rate is a very important factor for validity in a cohort study. This study analyzed the factors that affect the participation rate at one hospital-based birth cohort in South Korean. Methods The participants were recruited from the Mothers' and Children's Environmental Health study between 2006 and 2010. The analysis targeted 1751 mothers who participated in a birth cohort. We conducted analyses of general characteristics during pregnancy and those of infants at birth that affect the participation rate of the 6-month follow-up survey. Results The participation rate for the 6-month follow-up survey was 60.4%. The participation rate in the follow-up of the subsequent period decreased within a 5% to 10% range compared to the number of subjects. The participation rate of premature infants was 16.9% lower than that of a full-term infant (52.6% vs. 69.5%). Analysis showed a 16.7% difference between the participation rate of low-birthweight infants in follow-ups (53.7%) and the participation rate of infants with normal weight (70.4%). The participation rate of mothers who were employed during pregnancy was significantly lower for the 6-month follow-up compared to the participation rate of mothers who were unemployed during pregnancy. Conclusions In this study, factors such as premature birth, low-birthweight, and the employment status of the mother during pregnancy affected the participation rate of the follow-up survey for the birth cohort at six months. A specific strategy is needed to encourage survey participation for the high risk groups in the follow-ups.

Background: People with disabilities have higher prevalence rates and earlier onset of chronic disease than the non-disabled; therefore, their participation in health screening is important. This study evaluates the participation rate and trends in health screening of people with disabilities, and examines the association between their participation rate and disability characteristics, and socioeconomic status. Methods: Data on disability-related characteristics were collected from the National Disability Registry, and participants' corresponding health examination data were taken from the Korean National Health Insurance Corporation between 2002 and 2011. A total of 873,819 participants aged ${\geq}20$ years were analyzed in this study. Results: The rate of participation of people with disabilities in health screening has increased each year, but their participation rate is lower than that of the total population. The participation rate was lower in females than in males; the elderly group than in the younger group; those who live in city areas than rural areas; self-employed for health insurance than employees; those with an internal organ disability than those with an external physical disability; those with a severe disability than those with a mild disability; and those with a short-term disability than for those with a long-term disability. Conclusion: The factors associated with participation rate are age, sex, socioeconomic status, and disability characteristics. These findings indicate that health check-ups of people with disabilities should be promoted using an approach that takes into account the large individual differences in socioeconomic status and disability characteristics in this population.

This study explores how unmarried workers use their leisure time according to the 2009 Korean Time Use Survey. The purposes of this study are: 1) to investigate leisure time as it relates to leisure participation rates and leisure participation time and 2) to analyze the effect of socio-demographic variables on leisure time and leisure participation by unmarried workers. The following is a summary of the major findings. First, leisure participation differed with variations in leisure activities. Unmarried workers participated in media contact, human relations activities, and hobby activities more than other activities. Participation in learning activities was higher on weekdays than on Sunday. Men participated in sports and outdoor activities more than women on Sundays. The participation rate of media contact was the highest, while the participation rate of volunteer activities was the lowest. Second, influencing factors on leisure time included gender, age, monthly income, and gender role attitudes when work time was controlled. For example, unmarried workers with egalitarian attitudes spent less leisure time. Third, gender was the strongest determinant of leisure participation. The probability of women's leisure participation was higher than men except in regards to sports and outdoor activities, and hobby activities.

To predict the level of residents' participation in rural tourism project, we used agent-based model. The decision-making mechanism which calculates the utility related to attitude, subjective norm, perceived behavioral control of planned behavior theory was applied to the residents' decision to participate. As a result of the simulation over a period of 20 years, in the baseline scenario set similar to the general process of promoting rural projects, the proportion of indigenous people decreased and the participation rate decreased. In the scenarios with different learning frequencies in perceived behavioral control, overall participation rate decreased. Learning every five years had the effect of increasing the participation rate slightly. Participation rates increased significantly in the scenario that consider economic aspects and reputation in attitude and did not decline in the scenario where population composition was maintained. The virtuous cycle effect of subjective norm according to changes in participation rate due to influence of attitude and perceived behavioral control shows the dynamic relationship.

Background : Cancer is the leading cause of death and one of the largest burdens of disease in Korea. In 1996, the Ten year Plan for Cancer Control was formulated and the government then adopted the plan as a national policy. As part of this plan, the National Cancer Screening Program (NCSP) for Medicaid recipients was formulated, and the government adapted this in 1999. For low-income beneficiaries of the National Health Insurance Corporation (NHIC), the screening program has been in place since 2002. In 2002, the target cancers of NCSP were stomach, breast and cervical cancer. This study was conducted to examine the relationships between the participation rate, the abnormal screening rate and the socio-demographic factors associated with participation in the screening program. Methods : To analyze the participation rate and abnormal rate for the NCSP, we used the 2002 NCSP records. The information on the socio-demographic factors was available from the database of the beneficiaries in the NHIC and Medicaid. Results : The participation rate of the Medicaid beneficiaries for the stomach, breast and cervical cancer screening were 9.2%, 15.5% and 15.0%, respectively, and 11.3% and 12.5%, except cervical cancer which wasn't be included in the NCSP, for the beneficiaries of the NHIC. The abnormal rate of stomach, breast and cervical cancer screening were 25.7%, 11.2% and 21.0%, respectively, for the beneficiaries of Medicaid and 42.6% and 19.4% for the beneficiaries of the NHIC. On the multiple logistic regression analysis, gender, age and place of residence were significantly associated with participation rates of the NCSP. For stomach cancer, women participated in the NCSP more than men. The participation rate was higher among people in their fifties and sixties than for those people in their forties and those people over seventy years in age. For the breast and cervical cancer, people in their fifties were more likely to participate in the NCSP than people in their forties and people over sixty. For the place of residence, people in the rural areas participated more than those people in any other places. Conclusions : The above results show that the participation rate and abnormal rate were significantly associated with the socio-demographic factors. To improve the participation rate for the NCSP, more attention should be given to the underserved groups.

Objective : To analyze the factors affecting the participation rate in the health screening program of medical insurance. Method : We investigated the factors associated with the participation rate in the health screening program in Korea. Data were collected at the aggregate level from 145 employee health insurance societies and 227 self-employed health insurance societies from 1995 to 1997 Data were also collected at the individual level from four health insurance societies. This study hypothesized that the participation rate of the health screening program was related to 1) the characteristics of its members and the size of the health insurance society; 2) the specifications of the health screening program; 3) the venue of the health screening institution and the interests of individuals in the health screening program; and 4) the activities of the health insurance society. We used bivariate and multiple regression models to examine the factors on the participation rate of the health screening program. Results : First, in the case of dependents of on employee health insurance society, the ratio of dependents 40 years old and over, the average monthly contribution per household, the interest and satisfaction level of individuals in health screening, and the level of refunds for over-payment were all associated with the participation rate in the health screening program, accounting for 54.4% of the participation rate. Second, in case of those insured by the self-employed health insurance society, the interest and satisfaction level of individuals in health screening, the level of refunds for over-payment, and the performance level of on-the-spot health screening were statistically significant, accounting for 40.1% of the participation rate. Conclusion : The factors concerning the participation rate in the health screening program of medical insurance, in both a health insurance society and for individuals, were closely related to the age and gender of individuals and household contributions.

The occupational injury and illness(OII) was influenced by the various factors. This study was planned to investigate the pathway of the activities of OSHM on the rate of OII via worker's participation. The survey on the trend of the activities of OSHM was used. The sample size of manufacturing industry was 3,000 enterprises and that of construction was 1,000 enterprises. The survey was done by interview method with structure questionnaire. Questions about the activities of OHSM were integrated into one category using factor analysis. The enterprises with OII has more activities of OSHM than that without OII. Among enterprises with OII, the level of the activities of OSHM was positively correlated with the rate of OII. The activities of OSHM has influenced on the rate of OII directly and indirectly via worker's participation and the activities of prevention of accident. Worker's participation also has the direct effect and indirect effect on the rate of OII. Worker's participation in construction sector has more effect on OII than that in manufacturing sector.

Background and Aims: The National Cancer Screening Program (NCSP) for liver cancer was initiated in 2003 in Korea. The objective of this study was to evaluate the participation rate of the program and to provide preliminary information on its results based on data collected by the NCSP in 2009. Methods: The target population of the NCSP for liver cancer in 2009 was comprised of 373,590 adults aged ${\geq}40$ years at high risk for liver cancer. Participation rates and positivity rates were assessed in this population. Multivariate logistic regression analysis was performed to determine the factors associated with participation in the NCSP for liver cancer. Results: The overall participation rate was 37.9% and 1,126 participants were positive at screening. The highest participation rates were observed in women, those in their 60s, National Health Insurance beneficiaries, and individuals positive for hepatitis B surface antigen. Positivity rates for men, those in their 70s, Medical Aid Program recipients and individuals with liver cirrhosis were the highest in the respective categories of gender, age, health insurance type, and risk factor for liver cancer. Conclusions: The participation rates of the NCSP for liver cancer are still low, despite the fact that the program targets a high-risk group much smaller than the general population. Efforts to facilitate participation and to reduce disparities in liver cancer screening among Korean men and women are needed. These results provide essential data for evidence-based strategies for liver cancer control in Korea.

This study investigates effcts of HMO internal structural arrangements on performance, specially cost reduction measured by hospitalization rate. This study formulates formalization, centralization measured by decision-making participation, differentiation, and coordination as structural factors, considering coordination as an intermediate factor between the rest of structural factors and hospitalization rate. The commonly used HMO types is assumed not effective in explaining performance differences. For the empirical test, I use bootstrap regression analyses with 48 HMOs. The results of the analyses show that HMO types fail to explain differences in hospitalization rate. However, dicision-making participation and differention effectively reduce hospiatalization rate, while frmalization increases hospitalization rate and coordination has nonessential effect on hospitalization rate. And, formalization and decision-making participation positively contribute to achieve coordination in HMO. These findings suggest that the theoretical framework derived from rational-citingency theory of formal organization better explains performance differences of HMOs than HMO types.

The purpose of this study was to examine the impact of offering brand-name fast food at schools on student participation in school lunch. Two studies were conducted in Indiana, USA. In the first study, daily participation rate of 42 Indiana schools were compared between the days when brand-name fast food were offered and when they were not offered. The impact of brand-name fast food service on school lunch participation differed depending on the types of service offering brand-name fast food. Offering brand-name fast food solely as part of reimbursable meals or a-la-carte items was shown to induce students to the lunch option where brand-name fast food was offered. The second study examined the relationship of brand-name fast food service to monthly participation rate by analyzing secondary data of 1,282 Indiana schools using multiple regression analysis. Offering brand-name fast food was associated with monthly participation rate in school lunch only when schools offered them solely a-la-carte. Based on the results of two studies, it was concluded that offering brand-name fast food induced students from other lunch options to the options where brand-name fast food was offered on the day of service. However, increased or decreased participation in school lunch only on a few days could have not impacted average school lunch participation over a month. It is recommended that schools planning to offer brand-name fast food should make it available as part of reimbursable school lunches so that usual school lunch eaters would not be distracted to a-la-carte lines.
