Fracture Incidence and Characteristics in Young Adults Aged 18 to 49 Years: A Population-Based Study.

ABSTRACT: Although fractures in both the pediatric and, especially, the elderly populations have been extensively investigated, comparatively little attention has been given to the age group in between. Thus, we used the comprehensive (inpatient and outpatient) data resources of the Rochester Epidemiology Project to determine incidence rates for all fractures among young adult (age range, 18 to 49 years) residents of Olmsted County, Minnesota, in 2009 to 2011, and compared the distribution of fracture sites and causes in this young adult cohort with those for older residents aged 50 years or older. During the 3-year study period, 2482 Olmsted County residents aged 18 to 49 years experienced 1 or more fractures. There were 1730 fractures among 1447 men compared with 1164 among 1035 women, and the age-adjusted incidence of all fractures was 66% greater among the men (1882 [95% confidence interval 1793-1971] versus 1135 [95% CI 1069-1201] per 100,000 person-years; p?

Project description:ImportanceStroke remains the second leading cause of death worldwide. Approximately 10% to 15% of all strokes occur in young adults. Information on prognosis and mortality specifically in young adults is limited.ObjectiveTo determine short- and long-term mortality risk after stroke in young adults, according to age, sex, and stroke subtype; time trends in mortality; and causes of death.Design, setting, and participantsRegistry- and population-based study in the Netherlands of 15 527 patients aged 18 to 49 years with first stroke between 1998 and 2010, and follow-up until January 1, 2017. Patients and outcomes were identified through linkage of the national Hospital Discharge Registry, national Cause of Death Registry, and the Dutch Population Register.ExposuresFirst stroke occurring at age 18 to 49 years, documented using International Classification of Diseases, Ninth Revision, and International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, codes for ischemic stroke, intracerebral hemorrhage, and stroke not otherwise specified.Main outcomes and measuresPrimary outcome was all-cause cumulative mortality in 30-day survivors at end of follow-up, stratified by age, sex, and stroke subtype, and compared with all-cause cumulative mortality in the general population.ResultsThe study population included 15 527 patients with stroke (median age, 44 years [interquartile range, 38-47 years]; 53.3% women). At end of follow-up, a total of 3540 cumulative deaths had occurred, including 1776 deaths within 30 days after stroke and 1764 deaths (23.2%) during a median duration of follow-up of 9.3 years (interquartile range, 5.9-13.1 years). The 15-year mortality in 30-day survivors was 17.0% (95% CI, 16.2%-17.9%). The standardized mortality rate compared with the general population was 5.1 (95% CI, 4.7-5.4) for ischemic stroke (observed mortality rate 12.0/1000 person-years [95% CI, 11.2-12.9/1000 person-years]; expected rate, 2.4/1000 person-years; excess rate, 9.6/1000 person-years) and the standardized mortality rate for intracerebral hemorrhage was 8.4 (95% CI, 7.4-9.3; observed rate, 18.7/1000 person-years [95% CI, 16.7-21.0/1000 person-years]; expected rate, 2.2/1000 person-years; excess rate, 16.4/1000 person-years).Conclusions and relevanceAmong young adults aged 18 to 49 years in the Netherlands who were 30-day survivors of first stroke, mortality risk compared with the general population remained elevated up to 15 years later.

Project description:BackgroundHigh-resolution estimates of HIV burden across space and time provide an important tool for tracking and monitoring the progress of prevention and control efforts and assist with improving the precision and efficiency of targeting efforts. We aimed to assess HIV incidence and HIV mortality for all second-level administrative units across sub-Saharan Africa.MethodsIn this modelling study, we developed a framework that used the geographically specific HIV prevalence data collected in seroprevalence surveys and antenatal care clinics to train a model that estimates HIV incidence and mortality among individuals aged 15-49 years. We used a model-based geostatistical framework to estimate HIV prevalence at the second administrative level in 44 countries in sub-Saharan Africa for 2000-18 and sought data on the number of individuals on antiretroviral therapy (ART) by second-level administrative unit. We then modified the Estimation and Projection Package (EPP) to use these HIV prevalence and treatment estimates to estimate HIV incidence and mortality by second-level administrative unit.FindingsThe estimates suggest substantial variation in HIV incidence and mortality rates both between and within countries in sub-Saharan Africa, with 15 countries having a ten-times or greater difference in estimated HIV incidence between the second-level administrative units with the lowest and highest estimated incidence levels. Across all 44 countries in 2018, HIV incidence ranged from 2·8 (95% uncertainty interval 2·1-3·8) in Mauritania to 1585·9 (1369·4-1824·8) cases per 100 000 people in Lesotho and HIV mortality ranged from 0·8 (0·7-0·9) in Mauritania to 676·5 (513·6-888·0) deaths per 100 000 people in Lesotho. Variation in both incidence and mortality was substantially greater at the subnational level than at the national level and the highest estimated rates were accordingly higher. Among second-level administrative units, Guijá District, Gaza Province, Mozambique, had the highest estimated HIV incidence (4661·7 [2544·8-8120·3]) cases per 100 000 people in 2018 and Inhassunge District, Zambezia Province, Mozambique, had the highest estimated HIV mortality rate (1163·0 [679·0-1866·8]) deaths per 100 000 people. Further, the rate of reduction in HIV incidence and mortality from 2000 to 2018, as well as the ratio of new infections to the number of people living with HIV was highly variable. Although most second-level administrative units had declines in the number of new cases (3316 [81·1%] of 4087 units) and number of deaths (3325 [81·4%]), nearly all appeared well short of the targeted 75% reduction in new cases and deaths between 2010 and 2020.InterpretationOur estimates suggest that most second-level administrative units in sub-Saharan Africa are falling short of the targeted 75% reduction in new cases and deaths by 2020, which is further compounded by substantial within-country variability. These estimates will help decision makers and programme implementers expand access to ART and better target health resources to higher burden subnational areas.FundingBill & Melinda Gates Foundation.
