Marital status and cognitive impairment in the United States: evidence from the National Health and Aging Trends Study.

ABSTRACT: PURPOSE:We provide population-based longitudinal evidence of marital status differences in the risk of cognitive impairment and dementia in the United States. METHODS:Data were from the longitudinal National Health and Aging Trends Study, 2011-2018. The sample included 7508 respondents aged 65 years and older who contributed 25,897 person-year records. We estimated discrete-time hazard models to predict the risk of dementia and cognitive impairment, not dementia (CIND), as well as impairment in three major cognitive domains: memory, orientation, and executive function. RESULTS:Relative to their married counterparts, divorced and widowed elders had higher odds of dementia and CIND, as well as higher odds of impairment in each of the cognitive domains. Never-married elders had higher odds of impairment in memory and orientation than their married counterparts but did not differ significantly in the odds of impaired executive function, dementia, or CIND. Cohabiting elders did not differ significantly from married respondents on any measure of cognitive impairment. We found no gender differences in the associations between marital status and the measures of cognitive impairment. CONCLUSIONS:Marital status is a potentially important but overlooked social risk/protective factor for cognitive impairment. Divorced and widowed older adults are particularly vulnerable to cognitive impairment.

Project description:ImportanceInequalities in preterm infant mortality exist between population subgroups within the United States.ObjectiveTo characterize trends in preterm infant mortality by maternal race and socioeconomic status to assess how inequalities in preterm mortality rates have changed over time.Design, setting, and participantsThis was a retrospective longitudinal descriptive study using the US National Center for Health Statistics birth infant/death data set for 12 256 303 preterm infant births over 26 years, between 1995 and 2020. Data were analyzed from December 2022 to March 2023.ExposuresMaternal characteristics including race, smoking status, educational attainment, antenatal care, and insurance status were used as reported on an infant's US birth certificate.Main outcomes and measuresPreterm infant mortality rate was calculated for each year from 1995 to 2020 for all subgroups, with a trend regression coefficient calculated to describe the rate of change in preterm mortality.ResultsThe average US preterm infant mortality rate (IMR) decreased from 33.71 (95% CI, 33.71 to 34.04) per 1000 preterm births per year between 1995-1997, to 23.32 (95% CI, 23.05 to 23.58) between 2018-2020. Black non-Hispanic infants were more likely to die following preterm births than White non-Hispanic infants (IMR, 31.09; 95% CI, 30.44 to 31.74, vs 21.81; 95% CI, 21.43 to 22.18, in 2018-2020); however, once born, extremely prematurely Black and Hispanic infants had a narrow survival advantage (IMR rate ratio, 0.87; 95% CI, 0.84 to 0.91, in 2018-2020). The rate of decrease in preterm IMR was higher in Black infants (-0.015) than in White (-0.013) and Hispanic infants (-0.010); however, the relative risk of preterm IMR among Black infants compared with White infants remained the same between 1995-1997 vs 2018-2020 (relative risk, 1.40; 95% CI, 1.38 to 1.44, vs 1.43; 95% CI, 1.39 to 1.46). The rate of decrease in preterm IMR was higher in nonsmokers compared with smokers (-0.015 vs -0.010, respectively), in those with high levels of education compared with those with intermediate or low (-0.016 vs - 0.010 or -0.011, respectively), and in those who had received adequate antenatal care compared with those who did not (-0.014 vs -0.012 for intermediate and -0.013 for inadequate antenatal care). Over time, the relative risk of preterm mortality widened within each of these subgroups.Conclusions and relevanceThis study found that between 1995 and 2020, US preterm infant mortality improved among all categories of prematurity. Inequalities in preterm infant mortality based on maternal race and ethnicity have remained constant while socioeconomic disparities have widened over time.

Project description:Importance:A recent increase in suicide in the United States has raised public and clinical interest in determining whether a coincident national increase in suicide attempts has occurred and in characterizing trends in suicide attempts among sociodemographic and clinical groups. Objective:To describe trends in recent suicide attempts in the United States. Design, Setting, and Participants:Data came from the 2004-2005 wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and the 2012-2013 NESARC-III. These nationally representative surveys asked identical questions to 69?341 adults, 21 years and older, concerning the occurrence and timing of suicide attempts. Risk differences adjusted for age, sex, and race/ethnicity (ARDs) assessed trends from the 2004-2005 to 2012-2013 surveys in suicide attempts across sociodemographic and psychiatric disorder strata. Additive interactions tests compared the magnitude of trends in prevalence of suicide attempts across levels of sociodemographic and psychiatric disorder groups. The analyses were performed from February 8, 2017, through May 31, 2017. Main Outcomes and Measures:Self-reported attempted suicide in the 3 years before the interview. Results:With use of data from the 69?341 participants (42.8% men and 57.2% women; mean [SD] age, 48.1 [17.2] years), the weighted percentage of US adults making a recent suicide attempt increased from 0.62% in 2004-2005 (221 of 34?629) to 0.79% in 2012-2013 (305 of 34?712; ARD, 0.17%; 95% CI, 0.01%-0.33%; P?=?.04). In both surveys, most adults with recent suicide attempts were female (2004-2005, 60.17%; 2012-2013, 60.94%) and younger than 50 years (2004-2005, 84.75%; 2012-2013, 80.38%). The ARD for suicide attempts was significantly larger among adults aged 21 to 34 years (0.48%; 95% CI, 0.09% to 0.87%) than among adults 65 years and older (0.06%; 95% CI, -0.02% to 0.14%; interaction P?=?.04). The ARD for suicide attempts was also significantly larger among adults with no more than a high school education (0.49%; 95% CI, 0.18% to 0.80%) than among college graduates (0.03%; 95% CI, -0.17% to 0.23%; interaction P?=?.003); the ARD was also significantly larger among adults with antisocial personality disorder (2.16% [95% CI, 0.61% to 3.71%] vs 0.07% [95% CI, -0.09% to 0.23%]; interaction P?=?.01), a history of violent behavior (1.04% [95% CI, 0.35% to 1.73%] vs 0.00% [95% CI, -0.12% to 0.12%]; interaction P?=?.003), or a history of anxiety (1.43% [95% CI, 0.47% to 2.39%] vs 0.18% [95% CI, 0.04% to 0.32%]; interaction P?=?.01) or depressive (0.99% [95% CI, -0.09% to 2.07%] vs -0.08% [95% CI, -0.20% to 0.04%]; interaction P?=?.05) disorders than among adults without these conditions. Conclusions and Relevance:A recent overall increase in suicide attempts among adults in the United States has disproportionately affected younger adults with less formal education and those with antisocial personality disorder, anxiety disorders, depressive disorders, and a history of violence.
