Of the women, 82.9% and 10.0% reported that they w…

In line with the Sustainable Development Goals (SDGs), the reduction of the under-5 mortality rate to ≤25 deaths per 1000 live births by 2030 is the primary target of Myanmar’s national strategic plan for newborn and child health [1]. Myanmar made considerable strides in decreasing under-5 mortality with a 61% reduction between 1990 and 2019; [...]
Factors associated with the risk perception of Covid-19 infection and severe illness
Understanding COVID-19 risk perception may help inform public health messaging aimed at encouraging preventive measures and improving countermeasures against the pandemic. We conducted an online survey of 29,708 Japanese adults in February 2021 and estimated the associations between COVID-19 risk perception and a broad array of individual factors. Two logistic regressions were constructed to estimate factors associated with the risk perception of…
Pre- and post-Covid-19 all-cause mortality of Japanese citizens versus foreign residents living in Japan, 2015–2021
Immigrants in Japan face multiple health care challenges. There is limited research addressing how all-cause mortality differs between foreign residents and Japanese citizens, including the impact of the COVID-19 pandemic. We assessed whether all-cause mortality rates between Japanese citizens and foreign residents living in Japan differ, and whether these differentials changed after the start of the COVID-19 pandemic. We conducted a cross-sectio…
Excess deaths from non-Covid-19-related causes in Japan and 47 prefectures from January 2020 through May 2021 by place of death
Excess deaths, including all-causes mortality, were confirmed for the first time in Japan in April 2021. However, little is known about the indirect effects of COVID-19 on the number of non-COVID-19-related deaths. We then estimated the excess deaths from non-COVID-19-related causes in Japan and its 47 prefectures from January 2020 through May 2021 by place of death. Vital statistical data on deaths were obtained from the Ministry of Health, Labo…
Changes in Health Care Access during the Covid-19 Pandemic
The COVID-19 pandemic has disrupted health care access around the world, both for inpatients and outpatients. We applied a quasi-Poisson regression to national, monthly data on the number of outpatients, number of inpatients, length of average hospital stay, and the number of new hospitalizations from March 2015 to October 2021 to assess how these outcomes changed between June 2020 to October 2021. The number of outpatient visits were lower-than-…
