Technical efficiency and resilience of health systems in Japan during the Covid-19 pandemic
It is widely recognized that in resilient health systems, efficient utilization of limited resources contributes to protecting lives against adverse external shocks. In this study, we estimated technical efficiency of local health systems in Japan during the COVID-19 pandemic, identified efficiency patterns, and compared health outcomes across these patterns to assess the contribution of efficiency to local health system resilience. We conducted …
Continuing to be cautious
Despite implementing no lockdowns and having a large elderly population, Japan had a low mortality rate due to COVID-19 compared to Europe and North America. The extent to which policies impacted person-to-person contact remains unclear. In this study, we examined changes in contact patterns and their association with behaviors and governmental recommendations in Japan during the pandemic. Ten social contact surveys were conducted between 2021 an…
Public investment on health and voter responses
This study examines the effect of COVID-19 vaccination on political support by leveraging Japan’s age-based vaccination rollout, which prioritized people aged 65 and older. Using a fuzzy regression discontinuity design, we found that vaccination increased favorable opinions of vaccination progress and infection control measures by 27.4% and 14.7%, respectively. These favorable opinions extended to positive perceptions of other infection control m…
Intergenerational effects of education on child mortality
Wealth inequalities in physical and cognitive impairments across Japan and Europe
Although prior research has provided insights into the association between country-level factors and health inequalities, key research gaps remain. First, most previous studies examine subjective rather than objective health measures. Second, the wealth dimension in health inequalities is understudied. Third, a handful of studies explicitly focus on older adults. To bridge these research gaps, this study measures wealth-related inequalities in ph…
Understanding the effects of informal caregiving on health and well-being
Social contact patterns in Japan in the Covid-19 pandemic during and after the Tokyo Olympic Games
Background: Social contact data in Japan have not been updated since 2011. The main objectives of this study are to report on newly collected social contact data, to study mixing patterns in the context of the COVID-19 pandemic, and to compare the contact patterns during and after mass events like the 2020 Olympic Games, which were held in 2021. Methods: We compared the number of contacts per day during and after the Olympic Games and on weekdays…
Health inequity in pandemic anxiety about Covid-19 infection and socioeconomic consequences in Japan
In contrast to existing European studies, evidence from the current study suggests contextual patterns of health inequity. Due to the prolonged socioeconomic consequences of the pandemic, multidisciplinary research on mental health issues and the quality of life remains an important research agenda in exploring socioeconomic measures in context, towards addressing inequity concerns
Kenkō seisaku no keizai bunseki
Social science research is increasingly making use of various kinds of big data generated by transactions. In the field of health economics and health policy, big data include medical claims databases, which record the expenditure of individuals on examinations, treatments, and medication, and are the healthcare equivalent of purchase records. The authors of this book comprehensively explore the current state of healthcare and long-term care in J…
Social contacts, vaccination decisions and influenza in Japan
BACKGROUND: Contact patterns and vaccination decisions are fundamental to transmission dynamics of infectious diseases. We report on age-specific contact patterns in Japan and their effect on influenza vaccination behaviour. METHODS: Japanese adults (N=3146) were surveyed in Spring 2011 to assess the number of their social contacts within a 24 h period, defined as face-to-face conversations within 2 m, and gain insight into their influenza-relate…
The dynamics of risk perceptions and precautionary behavior in response to 2009 (H1N1) pandemic influenza
BACKGROUND: The trajectory of an infectious disease outbreak is affected by the behavior of individuals, and the behavior is often related to individuals' risk perception. We assessed temporal changes and geographical differences in risk perceptions and precautionary behaviors in response to H1N1 influenza. METHODS: 1,290 US adults completed an online survey on risk perceptions, interests in pharmaceutical interventions (preventive intervention a…
Inventory of Data Sources for Estimating Health Care Costs in the United States
OBJECTIVE: To develop an inventory of data sources for estimating health care costs in the United States and provide information to aid researchers in identifying appropriate data sources for their specific research questions. METHODS: We identified data sources for estimating health care costs using 3 approaches: (1) a review of the 18 articles included in this supplement, (2) an evaluation of websites of federal government agencies, non profit …
Health-Related Activities in the American Time Use Survey
OBJECTIVES: The Bureau of Labor Statistics' American Time Use Survey (ATUS), launched in 2003, offers the first comprehensive look at how individuals spend their time. Health services researchers can use it to study time spent on a variety of health-related activities. We explain the survey's structure and provide an overview of the health-related activities reported by 34,693 respondents in 2003-2004. METHODS: For the ATUS, computer-assisted pho…
