Incidence rate ratios of motorcycle crash‐related hospitalizations within 1 year of dementia diagnosis in younger adults: A nationwide population‐based study in Taiwan

Background The cognitive impairment and motor deficiency due to dementia may adversely affect the ability skill related ride motorcycle. However, little information regarding incidence risk of motorcycle crash-related hospitalizations among patients with dementia. This study estimates rate ratios (IRR) between first-diagnosed non-dementia. Method In this retrospective population-based cohort study, we compared aged 40-64 years its age- sex- matched subjects without from Taiwan National Health Insurance Research Database entries Police-reported Traffic Accident Registry 2006 2015. was non-dementia cases using IRR, stratified by age, sex, charlson index. densities were estimated based on Poisson assumption. Result Over 1-year follow-up, 29.73 10.46 per 10,000 person-years for dementia, respectively, an IRR 2.84 (95% CI 1.99 4.06). Regardless any sex or index, higher in than ranging 1.07 0.49 2.37) 7.06 2.48 20.14). Unlike density decreased age Among them, highest 20.14) those 40-44. gender group, male (3.34, 95% 2.07 5.38) female (2.27, 1.32 3.89). effect comorbidities (IRR 4.17, 2.74 6.36). Conclusion Younger adults rise within 1 year after diagnosis which suggests reinforcement transport safety younger is needed.
