Do gender and racial/ethnic disparities in sleep duration emerge in early adulthood? Evidence from a longitudinal study of U.S. adults.

ABSTRACT: Gender and racial/ethnic disparities in sleep duration are well documented among the U.S. adult population, but we know little about how these disparities are shaped during the early course of adult life, a period marked by substantial changes in social roles that can influence time for sleep.Prospective data was used from the National Longitudinal Survey of Youth 1997 (NLSY97), a U.S.-based representative sample of persons born between 1980 and 1984, who were first interviewed in 1997. Sleep duration was assessed in 2002, 2007/2008, 2009, 2010, and 2011. Random-coefficient models were estimated to examine gender and racial/ethnic disparities in trajectories of sleep duration across early adulthood as a function of educational experiences, employment, and family relationships.Sleep duration declined during early adulthood. Women reported shorter sleep than men from age 18 to 22, but slept longer than men by age 28. Black Young adults reported sleep durations similar to those of White young adults until age 24, after which blacks slept less than whites. Educational experiences and employment characteristics reduced gender and racial/ethnic disparities, but family relationships exacerbated them.This study is the first to establish the emergence of gender and racial/ethnic disparities in sleep duration during early adulthood.

Project description:Sleep disturbances among pregnant women are increasingly linked to suboptimal maternal/birth outcomes. Few studies in the USA investigating sleep by pregnancy status have included racially/ethnically diverse populations, despite worsening disparities in adverse birth outcomes. Using a nationally representative sample of 71,644 (2,349 pregnant) women from the National Health Interview Survey (2004-2017), we investigated relationships between self-reported pregnancy and six sleep characteristics stratified by race/ethnicity. We also examined associations between race/ethnicity and sleep stratified by pregnancy status. We used average marginal predictions from fitted logistic regression models to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) for each sleep dimension, adjusting for sociodemographic and health characteristics. Pregnant women were less likely than non-pregnant women to report short sleep (PROverall = 0.75; 95% CI, 0.68-0.82) and more likely to report long sleep (PROverall = 2.06; 95% CI, 1.74-2.43) and trouble staying asleep (PROverall = 1.34; 95% CI, 1.25-1.44). The association between pregnancy and sleep duration was less pronounced among women aged 35-49 years compared to those <35 years. Among white women, sleep medication use was less prevalent among pregnant compared to non-pregnant women (PRWhite = 0.45; 95% CI, 0.31-0.64), but this association was not observed among black women (PRBlack = 0.98; 95% CI, 0.46-2.09) and was less pronounced among Hispanic/Latina women (PRHispanic/Latina = 0.82; 95% CI, 0.38-1.77). Compared to pregnant white women, pregnant black women had a higher short sleep prevalence (PRBlack = 1.35; 95% CI, 1.08-1.67). Given disparities in maternal/birth outcomes and sleep, expectant mothers (particularly racial/ethnic minorities) may need screening followed by treatment for sleep disturbances. Our findings should be interpreted in the historical and sociocultural context of the USA.

Project description:ImportanceHistorically marginalized racial and ethnic groups are generally more likely to experience sleep deficiencies. It is unclear how these sleep duration disparities have changed during recent years.ObjectiveTo evaluate 15-year trends in racial and ethnic differences in self-reported sleep duration among adults in the US.Design, setting, and participantsThis serial cross-sectional study used US population-based National Health Interview Survey data collected from 2004 to 2018. A total of 429 195 noninstitutionalized adults were included in the analysis, which was performed from July 26, 2021, to February 10, 2022.ExposuresSelf-reported race, ethnicity, household income, and sex.Main outcomes and measuresTemporal trends and racial and ethnic differences in short (<7 hours in 24 hours) and long (>9 hours in 24 hours) sleep duration and racial and ethnic differences in the association between sleep duration and age.ResultsThe study sample consisted of 429 195 individuals (median [IQR] age, 46 [31-60] years; 51.7% women), of whom 5.1% identified as Asian, 11.8% identified as Black, 14.7% identified as Hispanic or Latino, and 68.5% identified as White. In 2004, the adjusted estimated prevalence of short and long sleep duration were 31.4% and 2.5%, respectively, among Asian individuals; 35.3% and 6.4%, respectively, among Black individuals; 27.0% and 4.6%, respectively, among Hispanic or Latino individuals; and 27.8% and 3.5%, respectively, among White individuals. During the study period, there was a significant increase in short sleep prevalence among Black (6.39 [95% CI, 3.32-9.46] percentage points), Hispanic or Latino (6.61 [95% CI, 4.03-9.20] percentage points), and White (3.22 [95% CI, 2.06-4.38] percentage points) individuals (P < .001 for each), whereas prevalence of long sleep changed significantly only among Hispanic or Latino individuals (-1.42 [95% CI, -2.52 to -0.32] percentage points; P = .01). In 2018, compared with White individuals, short sleep prevalence among Black and Hispanic or Latino individuals was higher by 10.68 (95% CI, 8.12-13.24; P < .001) and 2.44 (95% CI, 0.23-4.65; P = .03) percentage points, respectively, and long sleep prevalence was higher only among Black individuals (1.44 [95% CI, 0.39-2.48] percentage points; P = .007). The short sleep disparities were greatest among women and among those with middle or high household income. In addition, across age groups, Black individuals had a higher short and long sleep duration prevalence compared with White individuals of the same age.Conclusions and relevanceThe findings of this cross-sectional study suggest that from 2004 to 2018, the prevalence of short and long sleep duration was persistently higher among Black individuals in the US. The disparities in short sleep duration appear to be highest among women, individuals who had middle or high income, and young or middle-aged adults, which may be associated with health disparities.

Project description:BackgroundIn 2020, primary care practices adopted telemedicine as an alternative to in-person visits. Little is known about whether access to telemedicine was equitable, especially among older patients. Our objectives were to (1) examine older adults' use of telemedicine versus in-person primary care visits and (2) compare hospitalization for ambulatory care sensitive conditions (ACSCs) between the groups.MethodsIn this retrospective cross-sectional study of 17,103 patients aged ≥65 years seen at 32 clinics in the Mid-Atlantic, primary care patients were classified into two groups-telemedicine versus in person-based on the first visit between March and May 2020 and followed up for 14 days. Using multivariable logistic regression, we measured the odds of being seen via telemedicine versus in person as a function of patient demographics, comorbidities, and week of study period. We then measured the odds of ACSC hospitalization by visit modality.ResultsMean age was 75.1 years (SD, 7.5), 60.6% of patients were female, 64.6% white, 28.1% black, and 2.0% Hispanic. Overall, 60.3% of patients accessed primary care via telemedicine. Black (vs. white) patients had higher odds of using telemedicine (adjusted odds ratio [aOR], 1.30; 95% CI, 1.14-1.47) and Hispanic (vs. not Hispanic) patients had lower odds (aOR, 0.63; 95% CI, 0.42-0.92). Compared with the in-person group, patients in the telemedicine group had lower odds of ACSC hospitalization (aOR, 0.78; 95% CI, 0.61-1.00). Among patients who used telemedicine, black patients had 1.43 higher odds of ACSC hospitalization (95% CI, 1.02-2.01) compared with white patients. Patients aged 85 or older seen via telemedicine had higher odds of an ACSC hospitalization (aOR, 1.60; 95% CI, 1.03-2.47) compared with patients aged 65-74.ConclusionsThese findings support the use of telemedicine for primary care access for older adults. However, the observed disparities highlight the need to improve care quality and equity regardless of visit modality.
