Opposite educational gradients in sleep duration between Black and White adults, 2004-2018.
Ontology highlight
ABSTRACT: Objectives
To investigate the heterogeneous effects of education on sleep duration for Black and White adults and how the education effects changed between 2004 and 2018.Methods
A total of 251,994 adult participants in the 2004 to 2018 National Health Interview Survey were included in pooled cross-sectional data analyses. Separately for Black and White men and women, we calculated prevalence ratio and average marginal probability of short sleep (<7 hours) for each education level over the study period based on weighted logistic regression models.Results
Opposite educational gradients in short sleep were observed between Black and White adults. Greater educational attainment was associated with lower likelihood of short sleep among White adults but higher likelihood of short sleep among Black adults. Such heterogeneous educational gradients were robust after accounting for a set of socioeconomic, family, and health factors and persisted between 2004 and 2018.Conclusions
The health implications of education are not uniform in the US population, and heterogeneous education effects on sleep duration persisted over the past decade. More scholarly attention is needed to identify challenges and barriers that may be unique for race, sex, and education subpopulations to maintain healthy sleep.

Project description:At the population level, those with more education tend to report better sleep, mirroring the education gradient found in other health outcomes. But research has shown that higher educational attainment does not always confer the same health benefits for Non-Hispanic Black (Black) and Hispanic adults as it does for Non-Hispanic White (White) adults. It is therefore possible that the educational gradient in sleep varies across racial/ethnic groups in the United States. Using the 2004-2018 National Health Interview Survey (N = 356,048), we examined differences in self-reported sleep duration and sleep quality by level of educational attainment and race/ethnicity. Utilizing multinomial (sleep duration) and negative binomial (times in the past week with difficulty falling asleep and staying asleep) regression models, we found that, compared to their less educated counterparts, college or more educated Whites were more likely to report ideal sleep compared to short or long sleep, and also reported fewer times with difficulty falling or staying asleep. The education-sleep association was generally reversed for Black and Hispanic adults, with the worst sleep being reported by those with college-level education. These patterns remained after adjusting for health behaviors, health outcomes, and socioeconomic status. Our study suggests that education does not yield the same protective benefit for sleep among Black and Hispanic adults as it does for White adults, and that highly educated Black and Hispanic adults in particular experience a sleep disadvantage. The differential education gradient in sleep may, therefore, be an important factor underlying current racial and ethnic health disparities.

Project description:ObjectiveTo examine racial differences in sleep duration and its relationship with diabetes.Research design and methodsWe used data from a nationally representative sample of U.S. adults (n = 130,943) participating in the National Health Interview Survey from 2004 to 2011. Usual sleep duration was self-reported and categorized as <7 h (short), 7 h (optimal), and >7 h (long). Diabetes status was based on self-reported diagnosis from a health professional.ResultsParticipants' mean age was 50.6 years, 49% were men, and 13% were black. Compared with whites, blacks were more likely to report short sleep (37 vs. 28%) and less likely to get 7 h of sleep (24 vs. 33%). Diabetes (9,643 cases [9%] in whites and 3,612 cases [15%] in blacks) had a U-shaped distribution with sleep in whites (10, 7, and 9%, for short, optimal, and long sleep, respectively) and blacks (16, 13, and 15%). Suboptimal sleep duration was more strongly associated with diabetes in whites than in blacks among short (prevalence ratio 1.49 [95% CI 1.40-1.58] vs. 1.21 [1.09-1.34]) and long (1.32 [1.25-1.40] vs. 1.11 [1.00-1.23]) sleepers on the relative scale. Adjustment for socioeconomic status (SES) attenuated the short sleep-diabetes association in blacks (1.15 [1.02-1.29]), and the racial/ethnic difference in the short sleep-diabetes association became nonsignificant after SES adjustments.ConclusionsSuboptimal sleep duration was positively associated with diabetes in blacks and whites, although diabetes prevalence was higher at any level of sleep in blacks. Socioeconomic factors appear to partly explain the association for short sleep in blacks as well as disparity between racial groups.

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:BACKGROUND:Sleep has been suggested to influence breast cancer risk; however, the evidence is mixed. Black women have a higher prevalence of both short (<6?h) and long (?9?h) sleep duration and are more likely to develop more aggressive, hormone receptor-negative breast cancer. No study has examined the relationship between sleep and breast cancer in blacks. We focused on race-specific associations among the blacks. METHODS:In the Southern Community Cohort Study (SCCS), a prospective study of which two-thirds of the population were black, we prospectively investigated self-reported sleep duration in relation to overall breast cancer risk by estrogen (ER) and progesterone receptor (PR) status in all women and in black women alone. RESULTS:Sleep duration was not associated with risk of total or hormone receptor-positive breast cancer. However, we found an inverse relationship between sleep duration and risk of ER- and PR- breast cancer among all women and in black women alone. Compared to the reference group (8?h), black women who reported shorter sleep duration had an increased risk of ER-?PR-?breast cancer (odds ratios; ORs (95% confidence intervals; CIs): 2.13 (1.15, 3.93), 1.66 (0.92, 3.02), and 2.22 (1.19, 4.12) for <6, 6, and 7?h, respectively, (p for trend, 0.04). CONCLUSIONS:Short sleep duration may be a risk factor for hormone receptor-negative breast cancer among black women.

Project description:Housing environments can directly and indirectly affect sleep, and blacks are more likely than whites to live in suboptimal housing conditions, which may independently contribute to sleep disparities. However, few large-scale epidemiological studies consider the potential influence of housing type on sleep health. Using data from the 2004-2015 National Health Interview Survey, we investigated overall and Black-White differences in the association between housing type (house/apartment versus mobile home/trailer) and sleep duration as well as sleep difficulties among 226,208 adults in the U.S. Poisson regression with robust variance was used to estimate sex-specific prevalence ratios (PR) for sleep categories, first comparing houses/apartments to mobile homes/trailers and then blacks to whites within housing types. All models were adjusted for age, educational attainment, income, occupational class, self-reported general health status, and region of residence. Compared to participants living in houses/apartments, the prevalence of short sleep was higher for men (PR = 1.05 (95% confidence interval (CI): 1.02-1.08)) and women (PR = 1.07 (95% CI: 1.04-1.09)) in mobile homes/trailers. Black men (PR = 1.26 (95% CI: 1.21-1.30)) and women (PR = 1.24 (95% CI: 1.20-1.27)) in a house/apartment were more likely to be short sleepers than their white counterparts. There was generally no significant difference in sleep characteristics (except long sleep) between black and white men in mobile homes/trailers after adjustments, and black men in houses/apartments as well as black women in both housing types were less likely to report sleep difficulties although being more likely to report short sleep. Overall, individuals in mobile homes/trailers, which may represent suboptimal housing, had worse sleep than those in houses/apartments; and racial differences in the quality of houses and apartments are likely to greatly vary in ways that still contribute to sleep disparities. Race-sex group differences in sleep duration among residents in a house/apartment and even a lack of racial difference among individuals living in mobile homes/trailers support the need for more research on residential environments and eventually multi-level interventions designed to reduce sleep disparities.

Project description:To document trends in self-reported sleep duration for the noninstitutionalized U.S. civilian population from 2004 to 2017 and examine how sleep trends vary by race/ethnicity. We use data from the National Health Interview Survey (NHIS) for U.S. noninstitutionalized adults aged 18-84 from 2004 to 2017 (N = 398 382). NHIS respondents were asked how much they slept in a 24-hour period on average, which we categorized as ≤6 hr (short sleep), 7-8 hr (adequate sleep), and ≥9 hr (long sleep). We used multinomial logistic regression models to examine trends in self-reported sleep duration and assess race/ethnic differences in these trends. Our models statistically adjusted for demographic, socioeconomic, familial, behavioral, and health covariates. The prevalence of short sleep duration was relatively stable from 2004 to 2012. However, results from multinomial logistic regression models indicated that there was an increasing trend toward short sleep beginning in 2013 (b: 0.09, 95% CI: 0.05-0.14) that continued through 2017 (b: 0.18, 95% CI: 0.13-0.23). This trend was significantly more pronounced among Hispanics and non-Hispanic blacks, which resulted in widening racial/ethnic differences in reports of short sleep. Recent increases in reports of short sleep are concerning as short sleep has been linked with a number of adverse health outcomes in the population. Moreover, growing race/ethnic disparities in short sleep may have consequences for racial and ethnic health disparities.

Project description:INTRODUCTION:Both short and long sleep have been associated with higher mortality. However, most studies are conducted in predominantly White or Asian populations and little is known about the sleep-mortality relationship in Blacks. Given the high prevalence of short and long sleep in Blacks, it is important to examine the health effects of sleep in this population. METHODS:We studied sleep duration in relation to all-cause, cardiovascular and cancer mortality in 55,375 participants age 40-79 at enrollment in the Southern Community Cohort Study, of whom ?2/3 are Black. Weekday and weekend sleep durations were self-reported. Mortality follow up started at baseline (2002-2009) and was regularly updated until 2015 via linkage to Social Security Administration and the National Death Index. We used Cox proportional hazards model adjusting for multiple covariates to estimate relative risks associated with sleep duration. RESULTS:We found U-shaped relationships between weekday and weekend sleep duration and all-cause mortality, with the effects stronger in Whites than Blacks. Risks for all-cause mortality were significantly elevated by about 25% among Whites and about 10% among Blacks reporting either less than 5 hours or more than 9 hours of sleep compared with those reporting 8 hours of sleep. The associations among Whites but not Blacks were even stronger for cardiovascular disease mortality, whereas no association between sleep duration and cancer mortality was found in either group. CONCLUSIONS:Our results suggest that short and long sleep durations may be weaker predictors of total and cardiovascular mortality in Blacks than in Whites.

Project description:Reduced sleep duration and sleep deprivation have been associated with cognitive impairment as well as decreased white matter integrity as reported by experimental studies. However, it is largely unknown whether differences in sleep duration and sleep quality might affect microstructural white matter and cognition. Therefore, the present study aims to examine the cross-sectional relationship between sleep duration, sleep quality, and cognitive performance in a naturalistic study design, by focusing on the association with white matter integrity in a large sample of healthy, young adults. To address this, 1,065 participants, taken from the publicly available sample of the Human Connectome Project, underwent diffusion tensor imaging. Moreover, broad cognitive performance measures (NIH Cognition Toolbox) and sleep duration and quality (Pittsburgh Sleep Quality Index) were assessed. The results revealed a significant positive association between sleep duration and overall cognitive performance. Shorter sleep duration significantly correlated with fractional anisotropy (FA) reductions in the left superior longitudinal fasciculus (SLF). In turn, FA in this tract was related to measures of cognitive performance and was shown to significantly mediate the association of sleep duration and cognition. For cognition only, associations shift to a negative association of sleep duration and cognition for participants sleeping more than 8 hr a day. Investigations into subjective sleep quality showed no such associations. The present study showed that real-world differences in sleep duration, but not subjective sleep quality are related to cognitive performance measures and white matter integrity in the SLF in healthy, young adults.

Project description:ImportanceThere are substantial and increasing educational differences in US adult life expectancy. To reduce social inequalities in mortality, it is important to understand how specific causes of death have contributed to increasing educational differences in adult life expectancy in recent years.ObjectiveTo estimate the relationship of specific causes of death with increasing educational differences in adult life expectancy from 2010 to 2017.Design, setting, and participantsSerial cross-sectional study of 4 690 729 deaths recorded in the US National Vital Statistics System in 2010 and 2017.ExposuresSex, race/ethnicity, and educational attainment.Main outcomes and measuresLife expectancy at age 25 years and years of life lost between ages 25 and 84 years by cause of death.ResultsThe analysis included a total of 2 211 633 deaths in 2010 and 2 479 096 deaths in 2017. Between 2010 and 2017, life expectancy at age 25 significantly declined among white and black non-Hispanic US residents from an expected age at death of 79.34 to 79.15 years (difference, -0.18 [95% CI, -0.23 to -0.14]). Greater decreases were observed among persons with a high school degree or less (white men: -1.05 years [95% CI, -1.15 to -0.94], white women: -1.14 years [95% CI, -1.24 to -1.04], and black men: -0.30 years [95% CI, -0.56 to -0.04]). White adults with some college education but no 4-year college degree experienced similar declines in life expectancy (men: -0.89 years [95% CI, -1.07 to -0.73], women: -0.59 years [95% CI, -0.77 to -0.42]). In contrast, life expectancy at age 25 significantly increased among the college-educated (white men: 0.58 years [95% CI, 0.42 to 0.73], white women: 0.78 years [95% CI, 0.57 to 1.00], and black women: 1.70 years [95% CI, 0.91 to 2.53]). The difference between high- and low-education groups increased from 2010 to 2017, largely because life-years lost to drug use increased among those with a high school degree or less (white men: 0.93 years [95% CI, 0.90 to 0.96], white women: 0.50 years [95% CI, 0.47 to 0.52], black men: 0.75 years [95% CI, 0.71 to 0.79], and black women: 0.28 years [95% CI, 0.25 to 0.31]).Conclusions and relevanceIn this serial cross-sectional study, estimated life expectancy at age 25 years declined overall between 2010 and 2017; however, it declined among persons without a 4-year college degree and increased among college-educated persons. Much of the increasing educational differences in years of life lost may be related to deaths attributed to drug use.
