08 (95% confidence interval, 1.52-2.83). Women's quitting smoking after-but not before-pregnancy awareness was associated with decreased risk of partners' continued smoking the odds ratio of women's quitting after pregnancy awareness compared with never smoking was 0.57 (95% confidence interval, 0.40-0.80). About one-third of partners who continued to smoke did so indoors. Older age, lower education, workplace SHS exposure, and women's quitting smoking after pregnancy awareness were associated with increased risk of partners' indoor smoking. Workplace SHS exposure and pregnant women's smoking history were associated with continued smoking and indoor smoking among partners of non-smoking pregnant women.Workplace SHS exposure and pregnant women's smoking history were associated with continued smoking and indoor smoking among partners of non-smoking pregnant women. This longitudinal study aimed to examine the changes in psychological distress of the general public from the early to community-transmission phases of the COVID-19 pandemic and to investigate the factors related to these changes. An internet-based survey of 2,400 Japanese people was conducted in two phases early phase (baseline survey February 25-27, 2020) and community-transmission phase (follow-up survey April 1-6, 2020). The presence of severe psychological distress (SPD) was measured using the Kessler's Six-scale Psychological Distress Scale. The difference of SPD percentages between the two phases was examined. Mixed-effects ordinal logistic regression analysis was performed to assess the factors associated with the change of SPD status between the two phases. Surveys for both phases had 2,078 valid respondents (49.3% men; average age, 50.3 years). In the two surveys, individuals with SPD were 9.3% and 11.3%, respectively, demonstrating a significant increase between the two phases (P = 0.005). Significantly higher likelihood to develop SPD were observed among those in lower (ie, 18,600-37,200 United States dollars [USD], odds ratio [OR] 1.95; 95% confidence interval [CI], 1.10-3.46) and the lowest income category (ie, <18,600 USD, OR 2.12; 95% CI, 1.16-3.86). Furthermore, those with respiratory diseases were more likely to develop SPD (OR 2.56; 95% CI, 1.51-4.34). From the early to community-transmission phases of COVID-19, psychological distress increased among the Japanese. Recommendations include implementing mental health measures together with protective measures against COVID-19 infection, prioritizing low-income people and those with underlying diseases.From the early to community-transmission phases of COVID-19, psychological distress increased among the Japanese.

We checked data quality indicators for PBCRs to confirm a comparability. We calculated age-standardized annual incidence and mortality of cancer for all-site, thyroid, and leukemia by calendar year and sex, as did for Tochigi Prefecture and all of Japan as a reference for comparison. We applied joinpoint trend analysis to test an apparent trend in incidence and mortality.ResultsThe corrected incidence data from the Fukushima Cancer Registry had sufficient quality comparable to other PBCRs. For the age-standardized annual incidence by sex and cancer type in Fukushima and Tochigi, we did not detect any joinpoint in trend with statistical significance. Cancer incidence gently increased from 2008 to 2015 nationwide. Incidence and mortality of cancer for Fukushima before the accident was very close to that for Tochigi.ConclusionsWe interpreted the incidence statistics of cancer for Fukushima residents between 2008 and 2015. Our results will provide fundamental statistics for subsequent researchers to assess the relationship between the disaster and cancer incidence among Fukushima residents in the long term. The Japan Multi-institutional Collaborative Cohort (J-MICC) study was launched in 2005 to examine gene-environment interactions in lifestyle-related diseases, including cancers, among the Japanese. This report describes the study design and baseline profile of the study participants. The participants of the J-MICC Study were individuals aged 35 to 69 years enrolled from respondents to study announcements in specified regions, inhabitants attending health checkup examinations provided by local governments, visitors at health checkup centers, and first-visit patients at a cancer hospital in Japan. At the time of the baseline survey, from 2005 to 2014, we obtained comprehensive information regarding demographics, education, alcohol consumption, smoking, sleeping, exercise, food intake frequency, medication and supplement use, personal and family disease history, psychological stress, and female reproductive history, and collected peripheral blood samples. The baseline survey included 92,610 adults (mean age 55.2 [9.4] years, 44.1% men) from 14 study regions in 12 prefectures. The participation rate was 33.5%, with participation ranging from 19.7% to 69.8% in different study regions. The largest number of participants was in the age groups of 65-69 years for men and 60-64 years for women. Gemcitabine There were differences in body mass index, educational attainment, alcohol consumption, smoking, and sleep duration between men and women. The J-MICC Study collected lifestyle and clinical data and biospecimens from over 90,000 participants. This cohort is expected to be a valuable resource for the national and international scientific community in providing evidence to support longer healthy lives.The J-MICC Study collected lifestyle and clinical data and biospecimens from over 90,000 participants.
