Background:This study determined the current status of the incidence, management, and prognosis of stroke in Japan using a population-based stroke registry.Methods and Results:Shiga Stroke Registry is an ongoing population-based registry that covers approximately 1.4 million residents of Shiga Prefecture. Cases of acute stroke were identified using standard definitions through surveillance of both all acute-care hospitals with neurology/neurosurgery facilities and death certificates in 2011. A total of 2,956 stroke cases and 2,176 first-ever stroke cases were identified. The age- and sex-adjusted incidence rate for first-ever stroke using the 2013 European Standard Population as standard was per 100,000 person-years: 91.3 for ischemic stroke, 36.4 for intracerebral hemorrhage, and 13.7 for subarachnoid hemorrhage. It was estimated that approximately 220,000 new strokes occurred in 2011 in Japan. Among the 2,956 cases, most stroke patients underwent neuroimaging, 268 received surgical or endovascular treatment, and 2,158 had rehabilitation therapy; 78 patients received intravenous thrombolysis. A total of 1,846 stroke patients had died or were dependent at hospital discharge, and 390 died within 28 days of onset.Conclusions:Incidence rates of stroke by subtypes were clarified and the total number of new strokes in Japan was estimated. More than half of stroke patients die or become dependent after a stroke. This study re-emphasized the importance of public health measures in reducing the burden of stroke in Japan.

Background:Stroke is one of the leading causes of disability and mortality in Japan. The aim of the present analysis was to determine the non-acute survival rate after first-ever stroke using data from a large-scale population-based stroke registry in Japan.Methods and Results:Shiga Stroke Registry is an ongoing population-based registry of stroke, which covers approximately 1.4 million residents of Shiga Prefecture in central Japan. A total of 2,176 first-ever stroke patients, who were registered in 2011, were followed up until December 2013. The 2-year cumulative survival rates were estimated using Kaplan-Meier method according to index stroke subtype. Cox proportional hazards models were used to assess predictors of all-cause death. During a 2-year follow-up period, 663 patients (30.5%) died. The 2-year cumulative survival rate after first-ever stroke was 69.5%. There was heterogeneity in 2-year cumulative survival according to stroke subtype: lacunar infarction, 87.2%; large artery infarction, 76.1%; cardioembolic infarction, 55.4%; intracerebral hemorrhage, 65.9%; and subarachnoid hemorrhage, 56.7%. Older age, male sex, medical history, higher Japan coma scale score on admission, and stroke subtype were associated with risk of all-cause death in ≤2 years.Conclusions:In the present population-based stroke registry with a real-world setting in Japan, 2-year cumulative mortality after first-ever stroke is still high (>30%), particularly for cardioembolic infarction, subarachnoid hemorrhage and intracerebral hemorrhage.

Background: Although underweight young women are targets for interventions to prevent low bone mineral density (BMD), the relationship between change in body mass index (BMI) from youth to older age and BMD has not been widely investigated in community dwellers.Methods: In 749 healthy Japanese women aged 40–74 years, BMD was measured by quantitative ultrasound and anthropometric measurements, and BMI was calculated from body weight and height. The BMI of participants at age 20 years was estimated by self-reported body weight and their present height. They were classified into four groups according to the presence of underweight (BMI <18.5 kg/m2) at 20 and/or at present. Logistic regression models were used to estimate multivariate-adjusted odds ratios (ORs) of the presence of underweight at 20 and/or at present for osteopenia (BMD T score <−1 standard deviations) compared with participants with BMI ≥18.5 kg/m2 both at 20 and at present.Results: The participants who were underweight both at 20 and at present had a higher OR for osteopenia compared with those with BMI ≥18.5 kg/m2 at 20 and at present (OR 3.94; 95% confidence interval [CI], 1.97–7.89). Those underweight only at present also had significantly increased OR of developing osteopenia (OR 2.95; 95% CI, 1.67–5.24). The OR of those underweight only at 20 was 0.87 (95% CI, 0.51–1.48).Conclusions: Current underweight was associated with increased risk for osteopenia among Japanese women, especially in those who were underweight both at 20 and at present. To prevent low BMD in the future, maintaining appropriate body weight might be effective for young underweight women.
