LOCAL POPULATION CHANGE AND VARIATIONS IN RACIAL INTEGRATION IN THE UNITED STATES, 2000-2010.

ABSTRACT: While population growth has been consistently tied to decreasing racial segregation at the metropolitan level in the United States, little work has been done to relate small-scale changes in population size to integration. We address this question through a novel technique that tracks population changes by race and ethnicity for comparable geographies in both 2000 and 2010. Using the Theil Index, we analyze the fifty most populous Metropolitan Statistical Areas in 2010 for changes in multigroup segregation. We classify local areas by their net population change between 2000 and 2010 using a novel unit of analysis based on aggregating census blocks. We find strong evidence that growing parts of rapidly growing metropolitan areas of the United States are crucial to understanding regional differences in segregation that have emerged in past decades. Multigroup segregation declined the most in growing parts of growing metropolitan areas. Comparatively, growing parts of shrinking or stagnant metropolitan areas were less diverse and had smaller declines in segregation. We also find that local areas with shrinking populations had disproportionately high minority representation in 2000 before population loss took place. We conclude that the regional context of population growth or decline has important consequences for the residential mixing of racial groups.

Project description:The prevalence of oocyte donation for in vitro fertilization (IVF) has increased in the United States, but little information is available regarding maternal or infant outcomes to improve counseling and clinical decision making.To quantify trends in donor oocyte cycles in the United States and to determine predictors of a good perinatal outcome among IVF cycles using fresh (noncryopreserved) embryos derived from donor oocytes.Analysis of data from the Centers for Disease Control and Prevention's National ART Surveillance System, to which fertility centers are mandated to report and which includes data on more than 95% of all IVF cycles performed in the United States. Data from 2000 to 2010 described trends. Data from 2010 determined predictors.Good perinatal outcome, defined as a singleton live-born infant delivered at 37 weeks or later and weighing 2500 g or more.From 2000 to 2010, data from 443 clinics (93% of all US fertility centers) were included. The annual number of donor oocyte cycles significantly increased, from 10,801 to 18,306. Among all donor oocyte cycles, an increasing trend was observed from 2000 to 2010 in the proportion of cycles using frozen (vs fresh) embryos (26.7% [95% CI, 25.8%-27.5%] to 40.3% [95% CI, 39.6%-41.1%]) and elective single-embryo transfers (vs transfer of multiple embryos) (0.8% [95% CI, 0.7%-1.0%] to 14.5% [95% CI, 14.0%-15.1%]). Good perinatal outcomes increased from 18.5% (95% CI, 17.7%-19.3%) to 24.4% (95% CI, 23.8%-25.1%) (P?<?.001 for all listed trends). Mean donor and recipient ages remained stable at 28 (SD, 2.8) years and 41 (SD, 5.3) years, respectively. In 2010, 396 clinics contributed data. For donor oocyte cycles using fresh embryos (n?=?9865), 27.5% (95% CI, 26.6%-28.4%) resulted in good perinatal outcome. Transfer of an embryo at day 5 (adjusted odds ratio [OR], 1.17 [95% CI, 1.04-1.32]) and elective single-embryo transfers (adjusted OR, 2.32 [95% CI, 1.92-2.80]) were positively associated with good perinatal outcome; tubal (adjusted OR, 0.72 [95% CI, 0.60-0.86]) or uterine (adjusted OR, 0.74 [95% CI, 0.58-0.94]) factor infertility and non-Hispanic black recipient race/ethnicity (adjusted OR, 0.48 [95% CI, 0.35-0.67]) were associated with decreased odds of good outcome. Recipient age was not associated with likelihood of good perinatal outcome.In the United States from 2000 to 2010, there was an increase in number of donor oocyte cycles, accompanied by an increase in good outcomes. Further studies are needed to understand the mechanisms underlying the factors associated with less successful outcomes.

Project description:ObjectivesTo analyze patterns of critical care medicine beds, use, and costs in acute care hospitals in the United States and relate critical care medicine beds and use to population shifts, age groups, and Medicare and Medicaid beneficiaries from 2000 to 2010.DesignRetrospective study of data from the federal Healthcare Cost Report Information System, American Hospital Association, and U.S. Census Bureau.SubjectsNone.InterventionsNone.SettingAcute care U.S. hospitals with critical care medicine beds.Measurements and main resultsFrom 2000 to 2010, U.S. hospitals with critical care medicine beds decreased by 17% (3,586-2,977), whereas the U.S. population increased by 9.6% (282.2-309.3M). Although hospital beds decreased by 2.2% (655,785-641,395), critical care medicine beds increased by 17.8% (88,235-103,900), a 20.4% increase in the critical care medicine-to-hospital bed ratio (13.5-16.2%). There was a greater percentage increase in premature/neonatal (29%; 14,391-18,567) than in adult (15.9%; 71,978-83,417) or pediatric (2.7%; 1,866-1,916) critical care medicine beds. Hospital occupancy rates increased by 10.4% (58.6-64.6%), whereas critical care medicine occupancy rates were stable (range, 65-68%). Critical care medicine beds per 100,000 total population increased by 7.4% (31.3-33.6). The proportional use of critical care medicine services by Medicare beneficiaries decreased by 17.3% (37.9-31.4%), whereas that by Medicaid rose by 18.3% (14.5-17.2%). Between 2000 and 2010, annual critical care medicine costs nearly doubled (92.2%; $56-108 billion). In the same period, the proportion of critical care medicine cost to the gross domestic product increased by 32.1% (0.54-0.72%).ConclusionsCritical care medicine beds, use, and costs in the United States continue to rise. The increasing use of critical care medicine by the premature/neonatal and Medicaid populations should be considered by healthcare policy makers, state agencies, and hospitals as they wrestle with critical care bed growth and the associated costs.

Project description:While young racial/ethnic groups are the fastest growing population in the United States, data about substance-related disorders among adolescents of various racial/ethnic backgrounds are lacking.To examine the magnitude of past-year DSM-IV substance-related disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, and tranquilizers) among adolescents of white, Hispanic, African American, Native American, Asian or Pacific Islander, and multiple race/ethnicity.The 2005 to 2008 National Survey on Drug Use and Health.Academic research.Noninstitutionalized household adolescents aged 12 to 17 years.Substance-related disorders were assessed by standardized survey questions administered using the audio computer-assisted self-interviewing method.Of 72 561 adolescents aged 12 to 17 years, 37.0% used alcohol or drugs in the past year; 7.9% met criteria for a substance-related disorder, with Native Americans having the highest prevalence of use (47.5%) and disorder (15.0%). Analgesic opioids were the second most commonly used illegal drugs, following marijuana, in all racial/ethnic groups; analgesic opioid use was comparatively prevalent among adolescents of Native American (9.7%) and multiple race/ethnicity (8.8%). Among 27 705 past-year alcohol or drug users, Native Americans (31.5%), adolescents of multiple race/ethnicity (25.2%), adolescents of white race/ethnicity (22.9%), and Hispanics (21.0%) had the highest rates of substance-related disorders. Adolescents used marijuana more frequently than alcohol or other drugs, and 25.9% of marijuana users met criteria for marijuana abuse or dependence. After controlling for adolescents' age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of substance-related disorders among Native Americans, adolescents of multiple race/ethnicity, adolescents of white race/ethnicity, and Hispanics compared with African Americans; African Americans did not differ from Asians or Pacific Islanders.Substance use is widespread among adolescents of Native American, white, Hispanic, and multiple race/ethnicity. These groups also are disproportionately affected by substance-related disorders.
