O4-04-03: Multicentre population-based dementia prevalence survey in Japan

ObjectivesTo determine the prevalence of diabetes mellitus (DM), prevalence of diabetic retinopathy (DR) and sight-threatening conditions among persons with DM aged 50 years and older in Sohag governorate in Upper Egypt.DesignPopulation-based, cross-sectional survey using the standardised Rapid Assessment of Avoidable Blindness with the addition of the Diabetic Retinopathy module methodology.SettingsSohag governorate in Egypt where 68 clusters were selected using probability proportional to population size. Households were selected using the compact segment technique.Participants4078 people aged 50 years and older in 68 clusters were enrolled, of which 4033 participants had their random blood sugar checked and 843 examined for features of DR.Primary and secondary outcomesThe prevalence of DM and DR; secondary outcome was the coverage with diabetic eye care.ResultsThe prevalence of DM was 20.9% (95% CI 19.3% to 22.5%). The prevalence in females (23.8%; 95% CI 21.4% to 26.3%) was significantly higher than in males (18.9%; 95% CI 17.1% to 20.7%) (p=0.0001). Only 38.8% of persons diagnosed with diabetes had good control of DM. The prevalence of DR in the sample was 17.9% (95% CI 14.7% to 21.1%). The prevalence in females was higher (18.9%; 95% CI 14.0% to 23.8%) than in males (17.1%; 95% CI 13.0% to 21.2%). Up to 85.3% of study participants have never had eye examination. Sight-threatening DR (R4 and/or M2) was detected in 5.2% (95% CI 3.4% to 7.0%) with only 2.3% having had laser treatment.ConclusionThe prevalence of uncontrolled DM in Sohag governorate in Egypt is higher than the national prevalence. There is a high prevalence of sight-threatening retinopathy and/or maculopathy with few people having access to diabetic eye care. A public health approach is needed for health promotion, early detection and management of DR.

Objective.The links between migrant status and psychosis have attracted considerable attention in recent decades. The aim of the study was to explore the demographic and clinical correlates of migrant v. Australia-born status in individuals with psychotic disorders using a large community-based sample.Method.Data were drawn from a population-based prevalence survey of adults with psychotic disorders. Known as the Survey of High Impact Psychosis (SHIP), it was conducted in seven Australian catchment areas in 2010. Logistic regression was used for the main analyses, examining associations of migrant status with sociodemographic and clinical variables.Results.Of the 1825 participants with psychotic disorders, 17.8% (n = 325) were migrants, of whom 55.7% (n = 181) were male. Compared to Australia-born individuals with psychosis, migrants were more likely to be currently married, to have completed a higher level at school, to have left school later, and to be employed with full-time jobs. Migrants with psychosis were either no different from or less impaired or disadvantaged compared to their Australian-born counterparts on a range of clinical and demographic variables.Conclusions.In a sample of individuals with psychotic disorders, there was no evidence to suggest that migrant status was associated with worse clinical or socio-economic outcomes compared to their native-born counterparts.

The Relationship

Objective.The relationship between acetabular dysplasia (HD) and hip osteoarthritis (OA) remains unclear, especially for mild forms of dysplasia. Our objectives were to estimate the prevalence of HD in a population-based sample with symptoms and to evaluate potential associations linking HD, hip OA, and hip pain.Methods.Individuals 40 to 75 years of age with symptoms in 1 or both hips were recruited during a multiregional prevalence survey. All study participants underwent examination and radiographs. Radiographs were evaluated using Kellgren-Lawrence staging (with stages ≥ 2 indicating hip OA) and HD measures [center-edge (CE) angle, acetabular inclination angle (HTE), acetabular depth (AD), and vertical center-anterior margin angle].Results.We studied both hips of 842 individuals (1684 hips), among whom 203 had hip OA. Compared to left hips, right hips had significantly smaller CE angles and significantly greater AD and HTE values (p ≤ 0.001). Overall, the prevalence of HD ranged from 7.6% to 22.2% of the hips depending on the measure used. The prevalence of HD was higher in individuals with hip OA, with significant differences for abnormal HTE (19.1% vs 11.4%; p < 0.0001) and abnormal CE (11.3% vs 7.5%; p = 0.04). By logistic regression, only abnormal HTE remained associated with OA. Same-side hip pain was not statistically more common in individuals with HD after stratification on OA status (p = 0.12).Conclusion.Our study confirms the relationship between OA and HD, particularly as defined based on the HTE angle.

Potential Public Health

Dementia affects 46.8 million of the world’s population, and is projected to increase to 131.5 million by 2050 (1). Increasingly, with no available disease-modifying drug or cure for the disease, preventive strategies are being pursued to curb the worldwide epidemic. Accumulating evidence supports the importance of dementia prevention, with seven risk factors (diabetes mellitus, midlife obesity, midlife hypertension, physical inactivity, depression, smoking, and low education) estimated to contribute to 9.6 million cases, equivalent to a third of Alzheimer’s disease worldwide (2). The potential public health impact of prevention is huge as a 20% reduction per decade from 2010 in the prevalence of these risk factors would translate to a 16.3% (1.5 million) reduction in dementia prevalence by 2050.

Background: Dementia prevalence is rising, and will double in the next 20 years. This study sought to understand the prevalence of dementia in hospitalized patients with stroke and TIA, differences in characteristics and impact on outcomes. Methods: Using the Canadian Institute of Health Information (CIHI) Discharge Abstract Database (DAD), all acute stroke and TIA admissions from April 2003 to March 2015 in Canada (excluding Quebec) were analyzed. Concurrent dementia at time of admission was assessed based on hospital diagnostic codes. Characteristics and in-hospital outcomes were compared in patients with vs. without dementia using chi-square and logistic regression. Results: During the observed period 464,741 patients were admitted to hospital for cerebrovascular syndromes (ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage (SAH) and TIA). Of those, 29,812 (6.4%) had a concurrent diagnosis of dementia, including 8.4% of patients ≥65 years. People with dementia had older median age (84 vs. 75 years; p<0.01), were more often female (59.6% vs. 49.3%; p<0.01) and more often had Charlson-Deyo comorbidity index ≥ 2 (62.1% v. 38.4%; p<0.01). They were less likely admitted with SAH (1.3% vs. 5.3%; p<0.01) and more likely coded as strokes with unidentified subtype (29.4% vs. 20.8%; p<0.01). Median length of stay (13 vs. 7 days; p<0.01) was longer. Patients with dementia were less likely discharged to another acute care facility (7.6% vs. 14.7%; p<0.01), rehabilitation facility (5.4% vs. 12.0%; p<0.01) or home independently (22.9% 48.9%; p<0.01); other outcomes are shown in the Table. Conclusions: Approximately 1 in 10 hospitalized stroke and TIA patients age ≥65 has coded dementia. Patients with stroke or TIA and dementia have higher mortality, face significantly more dependence after stroke and utilize greater healthcare resources than stroke patients without dementia. Early care planning and coordination are essential to optimize outcomes.
