Involuntary non-regular employment is a severe inequity problem worldwide, and it may significantly affect the mental health of employees. The present study aimed to examine the relationship between employment type and mental health. Additionally, the characteristics of involuntary non-regularly employed workers were explored. An online-based cross-sectional study was conducted in Japan, and 1566 participants were included in the data analysis. The eligible participants were divided into four categories: regularly employed (n = 1092), voluntary (n = 134), average (n = 233) and involuntary (n = 107) non-regularly employed individuals, respectively. Involuntary non-regular employment was associated with greater lack of vigour, anger-irritability, fatigue, anxiety, and depression. It was higher among women, those who were single or had no childcare, and those who had lower personal income or shorter working hours, or who tended not to practice relaxation activities. Lower personal income was associated with a risk of anxiety and depressive symptoms. Those individuals experiencing involuntary non-regular employment had a higher risk of poor mental health; subgroup analysis showed that this was particularly true among men. Both encouragement of employment stability via policy reform and workplace mental health support for involuntary non-regularly employed individuals are urgent health concerns., (© 2023 International Union of Psychological Science.)

Background: This study aimed to examine population-based characteristics of non-fatal self-harm in an urban area during pre- and peri-pandemic periods of COVID-19 by sex, age, and severity of self-harm, using pre-hospital medical emergency records., Methods: We used a registry of all pre-hospital medical records of self-harm cases that occurred in Kawasaki City, Japan, between January 2018 and December 2021. Adjusted incidence rate ratios (IRRs) with 95% confidence intervals (CIs) were calculated using Poisson regression models with the log-transformed population by year, sex, age group, and ward as an offset term., Results: During the 4-year study period, 1,534 patients were transported by ambulance due to non-fatal self-harm and were alive on arrival at the hospital. Among women, the number of non-fatal self-harm cases increased by 1.2-fold in 2021 compared with that in 2018. The incidence rate of "severe" non-fatal self-harm among men aged 19 years or younger in 2021 (IRR 4.82, 95% CI 1.25-18.65) and that among women aged 50-59 years in 2020 (IRR 2.51, 95% CI 1.06-5.95) significantly increased compared with that 2018 and 2019. The incidence rate of "mild" self-harm among women aged 20-29 years tended to be higher in 2021 than in 2018 and 2019 (IRR 1.42, 95% CI 0.95-2.12, P = 0.085)., Conclusions: During the peri-pandemic period of COVID-19, the incidence rate of "severe" non-fatal self-harm among men aged 19 years or younger and women aged 50-59 years, as well as that of "mild" self-harm among women aged 20-29 years, sharply increased compared with that during the pre-pandemic period. Our findings suggest that in urban areas during public health crises such as a pandemic, it is important to take measures to reduce the risk of non-fatal self-harm in young women, in addition to strengthening counseling and support for young women at risk for completed suicide.

Background: There are limited studies on healthcare resource use (HCRU) among adult asthma patients in Japan using real-world evidence, and analysis on acute treatment and associated costs stratified by disease severity is further limited. This study aimed to characterize the disease burden of severe asthma patients in Japan in terms of HCRU and comorbid medical conditions, with particular interest in oral corticosteroid (OCS) dependency., Methods: This retrospective cohort study of asthma patients used data from a claims database of diagnosis procedure combination hospitals in Japan. The severe asthma cohort included patients treated with OCS for more than 180 days in one year before the index date, with at least one asthma diagnosis claim. Comorbidity and drug use in the look-back period, HCRU, assumed OCS-related adverse events, and asthma exacerbations in the follow-up period were analyzed., Results: Costs associated with the treatment of severe asthma were approximately twice that of mild/moderate asthma, and the annual median cost of patients hospitalized due to asthma reached ¥448,000 (USD $4073). Annual asthma exacerbation rate was higher in the severe asthma cohort than in the mild/moderate cohort. Patients with longer OCS use in the previous year had higher risks of secondary adrenal insufficiency, osteoporosis, and pneumonia in the following year., Conclusions: OCS use among asthma patients in Japan incurred greater medical and economic burden. Better understanding of the disease characteristics including the severity of asthma and appropriate management of disease burden will lead to more optimal use of healthcare resources in Japan., Competing Interests: Conflict of Interest Y To received lecture fees from GlaxoSmithKline and AstraZeneca.

Introduction: The present study constructed a short form of the Healthy Eating Behavior Inventory suitable for use in the Japanese culture (HEBI-J) and confirmed the scale's preliminary reliability and validity., Methods: In Study 1, Japanese adults (N=75) completed a free-response questionnaire about healthy eating behaviours. Thematic analysis was used to identify three factors-balance, pattern, and restriction-associated with healthy eating behaviours and 12 items related to these healthy eating behaviours. In Study 2, Japanese office workers (N=784) completed two questionnaires regarding 12 items of healthy eating behaviours and the dietary stages of change., Results: Confirmatory factor analysis demonstrated that the three-factor model was appropriate (GFI=.94, AGFI=.90, CFI=.90, RMSEA=.08, SRMR=.53). Reliability was confirmed by alpha coefficients and the Spearman-Brown formula. Concurrent validity was confirmed by the relationship between the healthy eating stages., Conclusions: This study demonstrated the preliminary reliability and validity of the HEBI-J., (Copyright © 2015 Asia Oceania Association for the Study of Obesity.

Little is known about dissemination strategies that contribute to health information recognition. This study examined (a) health campaign exposure and awareness (slogan and logo recognition); (b) perceived communication channels; (c) differences between perceptions of researcher-developed and enhancement community health information materials; and (d) differences in campaign awareness and communication channels, according to Japanese community demographic characteristics. A cross-sectional survey (N = 508) was conducted in Tokigawa, Japan, in 2013. The Small Change Campaign focused on increasing physical activity and improving dietary habits. Information dissemination was carried out using leaflets, newsletters, posters, website, local public relations magazines, health classes, events, and online newsletters. The participants completed a survey assessing their campaign awareness (i.e., slogan and logo) and exposure to the informational materials presented during the campaign. Fewer than half (45.4%) knew the slogan, and only 24.4% were aware of the logo. Public relations magazines, leaflets, and newsletters were significantly better-perceived health communication channels. Researcher-developed and enhancement community health information materials were equally recognized (p = .34, w = .08). Furthermore, women and those who were employed were significantly more aware of the slogan, logo, and communication materials. Further research should explore effective communication strategies for community-based health promotion intervention via randomized control trials., (© 2015 Society for Public Health Education.)

A reversal design was used to evaluate the effects of vocal and written prompts as well as reinforcement on safe behavior (dismounting and walking bicycles or motorcycles on a sidewalk) on a university campus. Results indicated that an intervention that consisted of vocal and written prompts and reinforcement delivered by security guards was effective at increasing safe behavior exhibited by bicycle and motorcycle riders. No differences were observed between vehicle type or gender with regard to engagement in safe behavior.

Stray dogs are a public health risk factor when canine rabies is endemic. The Rabies Prevention Law has introduced measures to control stray dogs, but many dogs are still captured in Japan. In order to estimate the immune status of stray dogs for the purposes of risk management, we conducted a serological survey at the Hyogo Prefecture Animal Well-being Center. Only 27.7% of dogs brought into the Center (n=166) had protective immune status. This result suggests that there is the potential for reintroduction of canine rabies into stray dogs, leading to endemic rabies and its transmission to humans. Continued removal of stray dogs, education on rabies prevention and vaccination of dogs therefore remain important public health issues.

The South Oaks Gambling Screen (SOGS) was originally developed to screen for pathological gamblers in clinical settings, and its use has been expanded to other settings such as prevalence studies of pathological gambling in general populations. There are few studies of pathological gambling in Japan, except for the two studies on the development of the modified Japanese version of the SOGS. The present study examines the reliability and validity of the modified Japanese version of the SOGS using two different groups: a university student group (N = 96) and a gambler group (N = 66). Analyses of the modified Japanese version of the SOGS showed that there was sufficient internal consistency (alpha = .898) and reliability. The modified Japanese version of the SOGS demonstrated satisfactory validity in differentiating the university student group from the gambler group.

Bovine viral diarrhea virus (BVDV) has been segregated into two genotypes, type 1 and type 2. To determine the efficacy of the commercially available bovine viral diarrhea type 1 vaccine used in Japan against BVDV type 2, calves were infected with BVDV type 2 strain 890 4 weeks after administration of the vaccine. The vaccinated calves did not develop any clinical signs and hematological changes such as observed in unvaccinated calves after the challenge. Furthermore, the challenge virus was not recovered from the vaccinated calves throughout the duration of the experiment, whereas it was recovered from all unvaccinated calves. The bovine viral diarrhea vaccine used in Japan is efficacious against infection with BVDV type 2 strain 890.

Residual 60Co activity in five steel samples induced by neutrons from the Nagasaki atomic bomb has been measured within about 1000 m from the hypocenter. The chemical separation of cobalt and nickel from steel samples was performed, and cobalt-enriched samples were prepared for all samples. Gamma-ray measurements were carried out with a low-background well-type germanium detector. The gamma-ray spectra for five samples were compared with the spectrum of a control sample to ensure that the observed 60Co was actually induced by A-bomb neutrons. The activation of cobalt by environmental neutrons was also investigated. It has been shown that the present 60Co data are consistent with earlier Hashizume's data.

It was suggested that 3 strains of bovine viral diarrhea virus (BVDV) isolated from persistently infected calves in Tochigi prefecture in Japan belonged to BVDV type II. It was recognized lack of PstI site on the 5'-untranslated region of genome of them as well as BVDV type II reported previously. Inoculated with the 3 strains, the calves showed the mild decrease of platelet counts which was specific clinical sign of BVDV type II. We should report that the 3 strains were the first BVDV type II isolated in Japan. Neutralizing antibody titers of the antisera against the 3 strains using laboratory strains as neutralizing virus were lower than those of them using homologous strains. Therefore, it was indicated that the difference between BVDV type I and BVDV type II in the antigenicity.
