Trends in Self-Reported Sleep Duration among US Adults from 1985 to 2012.

ABSTRACT:

Study objective

The trend in sleep duration in the United States population remains uncertain. Our objective was to examine changes in sleep duration from 1985 to 2012 among US adults.

Design

Trend analysis.

Setting

Civilian noninstitutional population of the United States.

Participants

324,242 US adults aged ? 18 y of the National Health Interview Survey (1985, 1990, and 2004-2012).

Measurements and results

Sleep duration was defined on the basis of the question "On average, how many hours of sleep do you get in a 24-h period?" The age-adjusted mean sleep duration was 7.40 h (standard error [SE] 0.01) in 1985, 7.29 h (SE 0.01) in 1990, 7.18 h (SE 0.01) in 2004, and 7.18 h (SE 0.01) in 2012 (P 2012 versus 1985 < 0.001; P trend 2004-2012 = 0.982). The age-adjusted percentage of adults sleeping ? 6 h was 22.3% (SE 0.3) in 1985, 24.4% (SE 0.3) in 1990, 28.6% (SE 0.3) in 2004, and 29.2% (SE 0.3) in 2012 (P 2012 versus 1985 < 0.001; P trend 2004-2012 = 0.050). In 2012, approximately 70.1 million US adults reported sleeping ? 6 h.

Conclusions

Since 1985, age-adjusted mean sleep duration has decreased slightly and the percentage of adults sleeping ? 6 h increased by 31%. Since 2004, however, mean sleep duration and the percentage of adults sleeping ? 6 h have changed little.

Project description:BackgroundPublished evidence suggests an inverse association between sleep duration and body weight status.ObjectiveWe examined the association of sleep duration with eating behaviors reported by adult Americans to understand the relation between sleep duration and body weight status.DesignThis cross-sectional study used sleep duration and dietary data from the continuous NHANES conducted from 2005 to 2010 (n = 15,199, age ?20 y). Eating behaviors examined included the following: reporting of and energy from main meals (breakfast, lunch, and dinner) and snacks (before breakfast, after dinner, and after 2000 h), intermeal intervals, time of day of main meal reporting, and intakes of macronutrients and beverages. Multiple regression methods were used to examine the independent association of hours of sleep duration grouped as short (?6 h), average (7-8 h), and long (?9 h) with eating behavior outcomes.ResultsRelative to average-duration sleepers, a smaller percentage of short-duration sleepers mentioned breakfast, lunch (women only), and dinner in the recall (P ? 0.04). They also reported a lower mean percentage of energy from main meals but higher energy from all snacks (P ? 0.0004) and after 2000 h (P = 0.03). Short-duration sleepers reported the earliest eating time of the first episode and the latest time of the last eating episode. Absolute amounts of sugar and caffeine and percentage of energy from beverages (women only) were higher in short-duration sleepers. However, the total number of eating episodes and energy intake were not related with sleep duration.ConclusionsShort-duration sleepers began eating earlier and ended their eating later in the day, but despite the longer eating period, they did not report more eating events. Profiles of the relative contribution of main meals and snacks, at or after 2000 h eating, and beverages in short-duration sleepers were suggestive of eating behaviors that may increase energy intake, but 24-h energy intake did not differ among categories of sleep duration.

Project description:ObjectivesTo advance understanding of the relationship between discrimination and sleep duration and difficulties, with consideration of multiple dimensions of discrimination, and attention to concurrent stressors; and to examine the contribution of discrimination and other stressors to racial/ ethnic differences in these outcomes.DesignCross-sectional probability sample.SettingChicago, IL.ParticipantsThere were 2,983 black, Hispanic, and white adults.Measurements and resultsOutcomes included self-reported sleep duration and difficulties. Discrimination, including racial and nonracial everyday and major experiences of discrimination, workplace harassment and incivilities, and other stressors were assessed via questionnaire. In models adjusted for sociodemographic characteristics, greater exposure to racial (? = -0.14)) and nonracial (? = -0.08) everyday discrimination, major experiences of discrimination attributed to race/ethnicity (? = -0.17), and workplace harassment and incivilities (? = -0.14) were associated with shorter sleep (P < 0.05). The association between major experiences of discrimination attributed to race/ethnicity and sleep duration (? = -0.09, P < 0.05) was independent of concurrent stressors (i.e., acute events, childhood adversity, and financial, community, employment, and relationship stressors). Racial (? = 0.04) and non-racial (? = 0.05) everyday discrimination and racial (? = 0.04) and nonracial (? = 0.04) major experiences of discrimination, and workplace harassment and incivilities (? = 0.04) were also associated with more (log) sleep difficulties, and associations between racial and nonracial everyday discrimination and sleep difficulties remained after adjustment for other stressors (P < 0.05). Racial/ethnic differences in sleep duration and difficulties were not significant after adjustment for discrimination (P > 0.05).ConclusionsDiscrimination was associated with shorter sleep and more sleep difficulties, independent of socioeconomic status and other stressors, and may account for some of the racial/ethnic differences in sleep.

Project description:Self-reported short or long sleep duration has been associated with adverse cardiometabolic health outcomes in laboratory and epidemiologic studies, but interpretation of such data has been limited by methodologic issues.Adult respondents of the 2007-2008 US National Health and Nutrition Examination Survey (NHANES) were examined in a cross-sectional analysis (N=5649). Self-reported sleep duration was categorized as very short (<5 h), short (5-6 h), normal (7-8 h), or long (?9 h). Obesity, diabetes mellitus (DM), hypertension, and hyperlipidemia were objectively assessed by self-reported history. Statistical analyses included univariate comparisons across sleep duration categories for all variables. Binary logistic regression analyses and cardiometabolic factor as outcome, with sleep duration category as predictor, were assessed with and without covariates. Observed relationships were further assessed for dependence on race/ethnicity.In adjusted analyses, very short sleep was associated with self-reported hypertension (odds ratio [OR], 2.02, [95% confidence interval {CI},1.45-2.81]; P<0.0001), self-reported hyperlipidemia (OR, 1.96 [95% CI, 1.43-2.69]; P<0.0001), objective hyperlipidemia (OR, 1.41 [95% CI, 1.04-1.91]; P=0.03), self-reported DM (OR, 1.76 [95% CI, 1.13-2.74]; P=0.01), and objective obesity (OR, 1.53 [95% CI, 1.03-1.43]; P=0.005). Regarding short sleep (5-6 h), in adjusted analyses, elevated risk was seen for self-reported hypertension (OR, 1.22 [95% CI, 1.02-1.45]; P=0.03) self-reported obesity (OR, 1.21 [95% CI, 1.03-1.43]; P=0.02), and objective obesity (OR, 1.17 [95% CI, 1.00-1.38]; P<0.05). Regarding long sleep (?9 h), no elevated risk was found for any outcomes. Interactions with race/ethnicity were significant for all outcomes; race/ethnicity differences in patterns of risk varied by outcome studied. In particular, the relationship between very short sleep and obesity was strongest among blacks and the relationship between short sleep and hypertension is strongest among non-Hispanic whites, blacks, and non-Mexican Hispanics/Latinos.Short sleep duration is associated with self-reported and objectively determined adverse cardiometabolic outcomes, even after adjustment for many covariates. Also, these patterns of risk depend on race/ethnicity.
