RESUMO
In 1952, the Japanese Society for Hygiene had once passed a resolution at its 22nd symposium on population control, recommending the suppression of population growth based on the idea of cultivating a healthier population in the area of eugenics. Over half a century has now passed since this recommendation; Japan is witnessing an aging of the population (it is estimated that over 65-year-olds made up 27.7% of the population in 2017) and a decline in the birth rate (total fertility rate 1.43 births per woman in 2017) at a rate that is unparalleled in the world; Japan is faced with a "super-aging" society with low birth rate. In 2017, the Society passed a resolution to encourage all scientists to engage in academic researches to address the issue of the declining birth rate that Japan is currently facing. In this commentary, the Society hereby declares that the entire text of the 1952 proposal is revoked and the ideas relating to eugenics is rejected. Since the Society has set up a working group on the issue in 2016, there have been three symposiums, and working group committee members began publishing a series of articles in the Society's Japanese language journal. This commentary primarily provides an overview of the findings from the published articles, which will form the scientific basis for the Society's declaration. The areas we covered here included the following: (1) improving the social and work environment to balance between the personal and professional life; (2) proactive education on reproductive health; (3) children's health begins with nutritional management in women of reproductive age; (4) workplace environment and occupational health; (5) workplace measures to counter the declining birth rate; (6) research into the effect of environmental chemicals on sexual maturity, reproductive function, and the children of next generation; and (7) comprehensive research into the relationship among contemporary society, parental stress, and healthy child-rearing. Based on the seven topics, we will set out a declaration to address Japan's aging society with low birth rate.

In this paper, we examine the trend in Japan towards nonregular employment and its effects on marriage, childbirth, and childcare from the viewpoint of a decreasing societal birthrate. Although the decision to marry includes personal values and preferences, socioeconomic status factors such as income and employment type are also associated with the determinants of marriage. Nonregular employment workers have a lower rate and motivation for marriage than regular workers. Thus, socioeconomic disparity caused by employment needs to be minimized through governmental measures and policies. Nonregular employment is increasing among younger generations, and for them, maternity and childcare leave are especially vital. Employee insurance coverage should be expanded to function as a form of income security during these leaves of absence, such that nonregular workers are also covered. During the childcare period, which lasts more than 10 years, it is necessary to cover childrearing costs and also the time required to spend with children. If a single working parent is involved in childcare alone, there is the burden of both work and childcare. Additionally, long work hours can also impact workers that are not involved in childcare. This is a dilemma: a stable and regular employment is often necessary to achieve a higher education; however, it is difficult for nonregular employees to take care of and prepare children for higher education owing to limited financial means. Properly designed measures and policies are necessary to break this chain. Importantly, considerations about life and work are important for all workers, including nonregular workers, who are especially affected in terms of marriage, childbirth, and childcare.

Reproductive, maternal, newborn, and child health (RMNCH) care services could be critical entry points for preventing non-communicable diseases in women and children. In high-income countries, non-communicable diseases screening has been integrated into both the medical and public health systems. To integrate these services in low- and middle-income countries, it is necessary to closely examine its effectiveness and feasibility. In this systematic review, we evaluated the effectiveness of integrating gestational and non-gestational non-communicable diseases interventions and RMNCH care among women and children in low- and middle-income countries. This systematic review included randomized and quasi-randomized controlled trials published from 2000 to 2015. Participants included reproductive-age women, children < 5 years old, and RMNCH care providers. The included interventions comprised packaged care/services that integrated RMNCH services with non-communicable disease care. The outcomes were maternal and/or infant mortality and complications, as well as health care service coverage. We analyzed six studies from 7,949 retrieved articles. Yoga exercise (p < 0.01) and nutritional improvements (p < 0.05) were effective in reducing gestational hypertension and diabetes. Additionally, integrating cervical cancer and RMNCH services was useful for identifying potential cervical cancer cases. Interventions that integrate non-communicable disease care/screening and RMNCH care may positively impact the health of women and children in low- and middle-income countries. However, as primary evidence is scarce, further research on the effectiveness of integrating non-communicable disease prevention and RMNCH care is warranted.

The participation of women in the Japanese labor force is characterized by its M-shaped curve, which reflects decreased employment rates during child-rearing years. Although, this M-shaped curve is now improving, the majority of women in employment are likely to fall into the category of non-regular workers. Based on a review of the previous Japanese studies of the health of non-regular workers, we found that non-regular female workers experienced greater psychological distress, poorer self-rated health, a higher smoking rate, and less access to preventive medicine than regular workers did. However, despite the large number of non-regular workers, there are limited researches regarding their health. In contrast, several studies in Japan concluded that regular workers also had worse health conditions due to the additional responsibility and longer work hours associated with the job, housekeeping, and child rearing. The health of non-regular workers might be threatened by the effects of precarious employment status, lower income, a lower safety net, outdated social norm regarding non-regular workers, and difficulty in achieving a work-life balance. A sector wide social approach to consider life course aspect is needed to protect the health and well-being of female workers' health; promotion of an occupational health program alone is insufficient.

OBJECTIVES: The aim of this study was to examine whether the association between employment contract and self-rated health differs by household structure in a representative sample of employees in Japan. METHODS: The participants were 81,441 male and 64,471 female employees aged 18-59 years who had participated in the 2010 Comprehensive Survey of Living Conditions. We assessed the interactive effect of employment contract (permanent or precarious) and household structure (couple only, couple with children, single parent, single person, or other multi-person) on fair/poor health, adjusting for covariates by using logistic regression. We then calculated the relative poverty rate by employment contract and household structure. RESULTS: The interaction effect was significant for women (p<0.001) but not for men (p=0.413). A higher percentage of female precarious workers who lived in single-parent households (20.2%) reported fair/poor health compared with those in other types of households (10.4-13.2%), although the prevalence of fair/poor health did not differ substantially by household structure among female permanent workers. The relative poverty rates of female precarious workers who lived in single-parent households were higher compared with those of other female workers. CONCLUSIONS: Our results suggest that female precarious workers are not a homogeneous group and that those living in single-parent households suffer from poor health due to low income and insufficient coverage by insurance firms and family-based safety nets.

This study aimed to quantify the contributions of the factors that have influenced changes in income-related health inequalities. We used data from a nationally representative sample of Japanese men and women aged 20-59 years who participated in eight repeated cross-sectional surveys between 1986 and 2007. A concentration index (CI) was used to measure income-related inequalities in self-rated health (SRH) and decomposed into contributing factors. We then examined temporal changes in CIs and their contributing factors. Results showed that income-related inequalities in SRH, unfavourable to low-income groups, persisted throughout the study period. Despite widening income inequalities, inequalities in SRH narrowed during the period of economic stagnation since the late 1990s because of the profound deterioration in SRH among middle- to high-income groups. Decomposition analysis showed that income itself and unemployment or economic inactivity were the most important contributors to inequalities in SRH for both sexes at almost all time points. However, from 1986 to 2007, the relative contribution of income to these inequalities decreased from 78% to 14% in men and from 85% to 38% in women. By contrast, the relative contribution of unemployment or economic inactivity increased from 18% to 77% in men and from 10% to 31% in women. Our results suggest that a reduction in avoidable health inequalities could be achieved by reducing the influence of unemployment or economic inactivity on health.

BACKGROUND: Precarious employment is one of the social determinants of health. In 2010, 34.4% of Japanese workers fell into this employment category. The purpose of our study was to assess whether the use of annual health check-ups varied by worker contract type. METHODS: Using 2007 nationally representative survey data, we compared the annual health check-up compliance of permanently employed full-time workers versus that of precariously employed workers (hourly, dispatched, and fixed-term workers). RESULTS: Dispatched workers and hourly workers received health check-ups less often compared with permanent workers. Hourly young male workers received health check-ups five times less frequently than permanent workers. The percentage of workers who consulted a physician after receiving advice to do so did not differ by employment types, except in older men. CONCLUSIONS: In Japan, workers with precarious employment, most notably hourly and dispatched workers, had a lower rate of health check-ups compared with full-time workers in permanent positions.

This study assesses the possibility of a period effect on Japanese workers' health and its association with historical changes in the work environment. We used multi-year national cross-sectional surveys, the Comprehensive Survey of Living Conditions for 2001, 2004, and 2007, and estimated the period effect on the health of employed workers aged 18-65 years. The prevalence of ill-health indicators (poor self-rated health status, subjective symptoms, and the number of respondents receiving consultations from medical doctors and other health professionals) significantly increased during this period. Deteriorating trends in these health indicators persisted after adjusting for age and cohort effects and for individual factors such as employment, marital, and child-rearing status. Furthermore, after adjusting for income level as an individual factor, deteriorating trends remained for the poor self-rated health status of male employees, subjective symptoms of female employees, and receiving medical consultations for both genders. The health status of employed workers in Japan deteriorated, especially from 2004 to 2007, regardless of age and cohort effects. After taking individual socio-economic factors and the effects of the recession on society into consideration, we hypothesized a posteriori that the increase in precarious non-regular work may be the main factor underlying this period effect and may be the cause of the deterioration in workers' health.

STUDY DESIGN: This is a cross-national comparison of workers' compensation claims for back pain in Japan and the United States (US). OBJECTIVES: The main objective is to juxtapose rates of back pain claims in Japan and Washington state. Because the Washington state rate closely matches rates for other US states as well as the rate for the US as a whole, it is used to represent the US rate. A puzzle is to be framed: Why are back pain claim rates in Japan and the United States so disparate? SUMMARY OF BACKGROUND DATA: Occupational back pain is common among workers in both Japan and the United States. Wage compensation for time off work is also substantial in both countries and potentially induces time off work at least as much in Japan as in the United States. Accordingly, back pain claim rates in Japan seemingly would be on the same order of magnitude as rates in the United States. METHODS: Washington state rates are based on data from its state fund. Both Japan and Washington state rates are composed of the number of workers eligible to file worker compensation claims in a given year (denominator) and the number of back pain claims accepted during that year (numerator). Because rates may fluctuate from year-to-year, 5 years of data on rates are presented, 1995-1999. Central to the comparison are Japanese and Washington state rates of workers' compensation claims for back pain with more than 3 days compensated time loss from work. RESULTS: The back pain claim rate in 1999 was 60 times higher in Washington state than in Japan. The disparity in rates for the other years in the study (1995-1998) was similar. CONCLUSION: Back pain is common among workers both in Japan and the United States, but there is no simple or necessary relationship between that symptom and how it manifests itself in one country or another. Rather, the symptom is protean in its social manifestations. As for what shapes those manifestations-or, more specifically, what causes the startling disparity in back pain claim rates between Japan and the United States-that is a puzzle. Various solutions to the puzzle are discussed, but it remains essentially unsolved.

This study aims to clarify the effects of stress perception and related social indicators on three major musculoskeletal symptoms: low back, shoulder, and joint pains in a Japanese population. Twenty health-related variables (stress perception and 19 social indicators) and the three symptoms were obtained from the following Japanese national surveys: the Comprehensive Survey of Living Condition of the People on Health and Welfare, the System of Social and Demographic Statistics of Japan, and the Statistical Report on Health Administration Services. The results were compared among 46 Japanese prefectures in 1995 and 2001. By factor analysis, the 19 indicators were classified into three factors of urbanization, aging and life-regularity, and individualization. The prevalence of stress perception was significantly correlated to the 8 indicators of urbanization factor. Although simple correlation analysis revealed a significant relationship of stress perception only to shoulder pain (in both years) and low back pain (in 2001), the results of multiple regression analysis showed that stress perception and some urbanization factors were significantly associated with all the three symptoms in both years exclusive of joint pain in 1995. Taking the effects of urbanization into consideration, stress perception seems to be closely related to the complaints of musculoskeletal symptoms in Japan.
