However, the benefits of this regulation remain uncertain. This study examined the effects of the license renewal policy on collision and case fatality rates among older drivers.Methods: We conducted a controlled interrupted time-series analysis using monthly national police-reported motor vehicle collision data from January 2013 to December 2021. Drivers aged ≥75 years comprised the age group subject to the policy, and drivers aged 65-74 years served as the comparison group. Collision rates were modeled using negative binomial regression with age-group-specific population as the offset. Case fatality rates were modeled using Poisson regression with monthly collision counts as the offset. Estimates were expressed as rate ratios and ratios of rate ratios (RRRs).Results: The immediate post-policy level change in collision rates among drivers aged ≥75 years did not differ significantly from that among drivers aged 65-74 years (RRR, 1.061; 95% CI, 0.992-1.134). However, the post-policy monthly trend was significantly greater among drivers aged ≥75 years than among drivers aged 65-74 years (RRR, 1.004; 95% CI, 1.001-1.007). For case fatality rates, neither the immediate level change nor the post-policy monthly trend differed significantly between groups.Conclusion: The introduction of the license renewal policy was not associated with clear evidence of a population-level road safety benefit among drivers aged ≥75 years.","PeriodicalId":15799,"journal":{"name":"Journal of Epidemiology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149220485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The largest change was observed among patients aged 20-24 years in high-intensity regions (0.54 [95% CI, 0.46-0.63]), compared with middle-intensity (0.34 [95% CI, 0.27-0.41]) and low-intensity regions (0.42 [95% CI, 0.34-0.50]).

Guardians completed the BDHQ3y to report their child's dietary intake over the previous month and then 8-day weighed dietary records (DRs) over a year (2 days per season). From the BDHQ3y and DRs, energy-adjusted intakes of 44 nutrients and 26 food groups were estimated based on the density method.Results: Percentage differences in median intakes were within 10% for 26 nutrients (most energy-providing nutrients and several vitamins and minerals) and three food groups (cereals, fish/shellfish and milk/dairy products). The median Spearman's rank correlation coefficients were 0.31 (interquartile range [IQR], 0.23-0.40) for nutrients and 0.32 (IQR, 0.23-0.41) for food groups. Correlations exceeded 0.40 for 11 nutrients (eg, added sugar, dietary fiber and calcium) and nine food groups (eg, vegetables, fruits and milk/dairy products). Bland-Altman plots showed wide limits of agreement, with overestimation of intakes of protein, fats, carbohydrates, fruits, and milk/dairy products, as well as underestimation of intake of vegetables at higher intake levels. Similar findings were made when boys and girls were analyzed separately.Conclusion: The BDHQ3y has the potential to monitor population-level intakes of a range of nutrients.

To facilitate cross-cultural PA research, this study developed and validated a Japanese version of the PES (PES-JP) following cross-cultural adaptation guidelines.Methods: An online survey was conducted among 398 Japanese aged 20-59 years.Results: Exploratory analyses suggested a two-factor structure of the PES-JP (approach and avoidance), and both subscales demonstrated high internal consistency (α = 0.92 and 0.87, respectively). Concurrent validity was supported by associations with PA. The approach score was positively related to moderate-to-vigorous PA (MVPA; β = 0.19) and negatively to sitting time (β = -0.17). In contrast, the avoidance score showed the opposite pattern (β = -0.13 for MVPA, β = 0.20 for sitting). The global score (approach minus avoidance), which reflects the overall tendency to approach rather than avoid physical effort, showed a similar pattern to the approach dimension (β = 0.19 for MVPA, β = -0.22 for sitting). Test-retest reliability was acceptable (intraclass correlations, 0.65-0.81).Conclusion: The PES-JP demonstrates sound psychometric properties for assessing tendencies toward physical effort in Japanese adults and provides a useful tool for research on individual differences in PA behavior.

Although corporal punishment by caregivers has been legally prohibited since 2020, self-reported data remain limited on caregiver engagement in and recognition of specific maltreatment-related behaviors. This study described engagement in and recognition of 27 such behaviors.Methods: A cross-sectional, anonymous online survey was conducted in 2023 among caregivers of children in public elementary and junior high schools in a Japanese municipality. The questionnaire assessed self-reported engagement in 27 maltreatment-related behaviors and classification of each behavior as \"discipline,\" \"abuse,\" or \"neither.\" Associations between non-recognition as abuse and self-reported engagement were examined for each behavior.Results: Among 4,102 invited households, 1,098 caregivers were included. Behaviors for which the reporting criterion was not met were frequently reported, including yelling at the child (88.3%), hitting with the hand (59.1%), and verbal threats (47.3%), whereas most physical maltreatment-related behaviors meeting the reporting criterion were rarely reported. Recognition as abuse was low for several behaviors not meeting the reporting criterion, including yelling (19.1%), leaving a crying child unattended (43.4%), and hitting with the hand (45.7%). Across the 27 items, non-recognition as abuse correlated positively with reported engagement (R2 = 0.824, p < 0.001).Conclusions: Several behaviors not meeting the reporting criterion were commonly reported, and were often not classified as abuse. These findings suggest that even after the legal prohibition of corporal punishment, parenting support should specify which everyday behaviors may constitute corporal punishment or maltreatment.","PeriodicalId":15799,"journal":{"name":"Journal of Epidemiology","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149110587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
