Abstract
STUDY OBJECTIVES This review aims to assess the association between socioeconomic status (SES) and sleep health in the general population and the mediating effects of lifestyle and mental and physical health in this relationship. METHODS Observational studies testing the independent association between objective or subjective SES indicators and behavioral/physiological or clinical sleep health variables in the general population were included. PubMed/MEDLINE was searched for reports published from January 1990 to December 2019. The direction of effect was used as the primary effect measure, testing the hypothesis that low SES is associated with poor sleep health outcomes. Results are presented in the form of direction effect plots and synthesized as binomial proportions. RESULTS Overall, 336 studies were identified. A high proportion of effects at the expected direction was noted for measures of sleep continuity (100% for sleep latency, 50-100% for awakenings, 66.7-100% for sleep efficiency), symptoms of disturbed sleep (75-94.1% for insomnia, 66.7-100% for sleep-disordered breathing, 60-100% for hypersomnia), and general sleep satisfaction (62.5-100%), while the effect on sleep duration was inconsistent and depended on the specific SES variable (92.3% for subjective SES, 31.7% for employment status). Lifestyle habits, chronic illnesses, and psychological factors were identified as key mediators of the SES-sleep relationship. CONCLUSIONS Unhealthy behaviors, increased stress levels, and limited access to health care in low-SES individuals may explain the SES-sleep health gradient. However, the cross-sectional design of most studies and the high heterogeneity in employed measures of SES and sleep limit the quality of evidence. Further research is warranted due to important implications for health issues and policy changes. CITATION Papadopoulos D, Etindele Sosso FA.

Abstract
Objectives: Sleep problems are associated with a host of psychiatric disorders and have been attributed to race disparities in health and wellness. Studies of sleep and mental health do not typically consider within-group differences among Blacks. Thus, our understanding of how the sleep-mental health relationship among Caribbean Blacks is limited. This study identified sleep profiles among Caribbean-born Blacks who reside in the United States.Design: Latent class analysis and data from the National Survey of American Life Re-interview study were used to identify and compare the associations between 'sleep quality classes,' sociodemographic factors, stress, and depression risk among Caribbean Blacks.Results: Two sleep quality classes were identified - 'good sleep quality' and 'poor sleep quality' - with each class demonstrating a complex pattern of sleep experiences, and illuminating the association between sleep and depression risk.Conclusions: Findings provide insight into the influence of sociodemographic factors and social stressors on the sleep experience of Caribbean Blacks and the importance of considering within-group differences to better understand risk and resilience among Caribbean Blacks living in the United States. Findings also highlight the importance of screening for sleep problems in an effort to reduce the burden of depression experienced by this population.

J Sleep Res 2021; 31:e13421. [PMID: 34128264 DOI: 10.1111/jsr.13421] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 05/19/2021] [Accepted: 05/19/2021] [Indexed: 01/25/2023]
Abstract
Black women are under-represented in insomnia research. Further, cancer treatments increase the risk of late effects, thus affecting the sleep of psychologically and medically vulnerable cancer survivors. The Insomnia Severity Index (ISI) is widely used, but has not been researched in black women, and research in cancer survivors is limited. Prior studies demonstrate that psychometric properties of the ISI are not consistent across samples. This study examined the internal consistency and factor structure of the ISI in 29,500 participants from the Black Women's Health Study, an epidemiological study of black women in the United States. This cohort included 28,214 women without a cancer history and 1,286 cancer survivors. Exploratory, confirmatory and multigroup analyses were conducted to determine the psychometric properties of the ISI in these groups. The mean ISI score was 7.18 (standard deviation [SD] = 6.82). Findings supported the internal consistency reliability of the ISI in black women with (Ω = 0.896) and without (Ω = 0.892) a cancer history. Exploratory factor analyses supported a one-factor structure. Confirmatory factor analyses indicated that fit of this one-factor model was not robust in survivors (Satorra-Bentler chi-square [χSB2 (14)] = 197.78, comparative fit index [CFI] = 0.928, root mean-square error of approximation [RMSEA] = 0.143) or in women with no cancer history (χSB2 (14) = 2,887.93, CFI = 0.945, RMSEA = 0.121), but the alternative models we examined were not superior. Although factor structures in previous studies have varied considerably, we found a one-factor structure. Although internal consistency reliability was strong, factor analytic results did not further support the ISI. Inconsistencies in ISI measurement properties across studies may reflect differences in sample sizes and populations.

Abstract
BACKGROUND Despite remarkable achievements in ensuring health equity, racial/ethnic disparities in sleep still persist and are emerging as a major area of concern. Accumulating evidence has not yet been well characterized from a broad perspective. We conducted a scoping review of studies on sleep disparities by race/ethnicity to summarize characteristics of existing studies and identify evidence gaps. METHODS We searched PubMed, CINAHL, PsycINFO, and Web of Science databases for studies of racial/ethnic disparities in sleep. Studies that met inclusion criteria were retrieved and organized in a data charting form by study design, sleep measuring methods, sleep features, and racial/ethnic comparisons. RESULTS One hundred sixteen studies were included in this review. Most studies focused on disparities between Whites and Blacks. Disproportionately fewer studies examined disparities for Hispanic, Asian, and other racial/ethnic groups. Self-reported sleep was most frequently used. Sleep duration, overall sleep quality, and sleep disordered breathing were frequently studied, whereas other features including sleep efficiency, latency, continuity, and architecture were understudied, particularly in racial minority groups in the US. Current study findings on racial/ethnic disparities in most of sleep features is mixed and inconclusive. CONCLUSIONS This review identified significant evidence gaps in racial/ethnic disparities research on sleep. Our results suggest a need for more studies examining diverse sleep features using standardized and robust measuring methods for more valid comparisons of sleep health in diverse race/ethnicity groups.

Abstract
BACKGROUND Cancer survivors are prone to insomnia due to the physical and psychological sequelae of cancer and treatment. Individuals with insomnia may present symptoms of hyperarousal. Cancer survivors with insomnia and trait hyperarousal may require different clinical treatments than patients with insomnia without trait hyperarousal. To our knowledge, no study has examined these factors previously. This study examined the relation between insomnia and trait hyperarousal in cancer survivors. METHODS The sample included 160 individuals with previous cancer diagnoses who met DSM-5 criteria for insomnia disorder. Measures were collected with cross-sectional batteries of questionnaires, including the Insomnia Severity Index (ISI) and Hyperarousal Scale (HAS). This study is based on baseline data collected in a randomized clinical trial comparing CBT-I to acupuncture for cancer survivors with insomnia (Garland, Gehrman, Barg, Xie, & Mao, 2016). RESULTS Hyperarousal was positively associated with insomnia (ISI total score) in bivariate correlations (r = .350, p < .01) and linear regressions (F = 22.06, p < .001). In bivariate correlations, hyperarousal was related to perceptions about the consequences of disturbed sleep rather than reported sleep patterns. For example, hyperarousal was positively related to reported satisfaction (r = .159, p < .05) and worry about sleep (r = .415, p < .01), but not to falling asleep, staying asleep, or awakening too early. In regressions, younger age, insomnia duration, and worry about sleep were uniquely associated with hyperarousal when adjusting for insomnia (B = 0.200, B = 0.177, B = -0.182, p < .05). CONCLUSIONS Hyperarousal is associated with psychological appraisal of insomnia rather than reported sleep pattern. Younger age and longer duration of insomnia are associated with trait hyperarousal. These findings suggest targeting trait hyperarousal with amplified psychological treatment may lead to more personalized, effective treatment for insomnia.

Abstract
BACKGROUND Women and racial/ethnic minority groups in the U.S. report poor sleep health. While stress and alcohol use may contribute to sleep problems, few studies have examined the roles of stress and alcohol use on sleep among Black college women. Gender-racial ideology of Black womanhood may also play a role in sleep. This exploratory study sought to examine the relationships between stress, alcohol, ethnic-gender identity, and sleep. METHOD Guided by the biopsychosocial model and intersectionality theory, a cross-sectional study design recruited undergraduate women (18-24 years) attending a Historically Black College and University (HBCU) who self-identified as Black (N = 110). Participants completed the Insomnia Severity Index, Pittsburgh Sleep Quality Index, Perceived Stress Scale, Alcohol Use Disorders Test, and Giscombe Superwoman Schema Questionnaire. Univariate and multiple linear regressions were conducted to examine independent and multiple effects of stress, alcohol, and ethnic-gender identity on insomnia and sleep quality. RESULTS Participants (mean age 19.4 years) represented diverse ethnic groups, 53% American, 25% African, and 20% Caribbean. Nearly 23% reported moderate to severe levels of insomnia. Scores from the Perceived Stress Scale, the Alcohol Use Disorders Test, and the Giscombe Superwoman Schema Questionnaire were independently associated with insomnia and sleep quality. In multivariate analyses, only perceived stress exhibited a significant association with insomnia and sleep quality. CONCLUSION This exploratory study demonstrated that stress, excessive alcohol use, and ethnic-gender identity have relational impact on sleep health. Yet, stress may have greater importance and further research is needed to explore factors that mediated the relationship between stress and sleep.

Abstract
STUDY OBJECTIVE To assess whether perceived racial discrimination is associated with insomnia among Black women. METHODS Data on everyday and lifetime racism and insomnia symptoms were collected from questionnaires administered in the Black Women's Health Study, an ongoing prospective cohort of Black women recruited in 1995 from across the United States. In 2009, participants completed five questions on the frequency of discriminatory practices in daily life (everyday racism) and six questions on ever experiencing unfair treatment in key institutional contexts (lifetime racism). In 2015, the Insomnia Severity Index was used to assess insomnia symptoms. We estimated odds ratios and 95% confidence intervals for associations of racism with insomnia, using multivariable logistic regression models adjusted for potential confounders. RESULTS The 26 139 participants in the analytic sample were 40-90 years old (median = 57 years, SD = 9.6 years). Higher levels of everyday racism and lifetime racism were positively associated with subthreshold (ptrend < .01) and clinical insomnia (ptrend < .01). Results remained unchanged after further adjustment for sleep duration and shift work. CONCLUSIONS Higher levels of perceived racism were associated with increased odds of insomnia among middle-aged and elderly Black women. Thus, perceived racism may contribute to multiple racial health disparities resulting from insomnia. Helping minority populations cope with their experiences of discrimination may decrease the significant public health impact of sleep disruption and subsequent diagnoses.

Abstract
CONTEXT Although energy conservation strategies are recommended in clinical practice guidelines, little is known about changes in energy levels in oncology patients undergoing cancer treatment. OBJECTIVES The objective of this study was to identify variations in the trajectories of morning and evening energy levels and determine which characteristics predicted initial levels and the trajectories of morning and evening energy. METHODS Outpatients receiving chemotherapy (CTX) completed demographic and symptom questionnaires six times over two CTX cycles. Energy was assessed using the Lee Fatigue Scale. Hierarchical linear modeling was used to analyze the data. RESULTS A large amount of interindividual variability was found in the morning and evening energy trajectories. Patients who lived alone, had childcare responsibilities, had a lower functional status, did not exercise on a regular basis, had lower hemoglobin levels, had lower attentional function, higher trait anxiety, and higher sleep disturbance reported lower morning energy levels at enrollment. Variations in the trajectories of morning energy were associated with a higher body mass index and higher levels of morning energy and higher sleep disturbance scores. For evening energy, patients who were female, white, had lower functional status, and had lower attentional function and higher sleep disturbance reported lower evening energy levels at enrollment. Evening energy levels at enrollment were associated with changes in evening energy over time. CONCLUSION Patients undergoing CTX experience decrements in both morning and evening energy. The modifiable characteristics associated with these decrements can be used to design intervention studies to increase energy levels in these patients.

Abstract
OBJECTIVE The number of older adults with cancer is increasing. Given the limited amount of research and the inconsistent findings regarding age differences in common physical symptoms associated with cancer and its treatments, the purposes of this study, in a sample of oncology outpatients receiving chemotherapy (CTX), were to evaluate for age differences in demographic and clinical characteristics, as well as in occurrence rates of and severity ratings for fatigue, decrements in energy, and sleep disturbance. In addition, using regression analysis techniques, within and across age groups, demographic and clinical characteristics associated with the severity of each symptom were evaluated. METHODS Patients (n = 1343) were dichotomized into younger (<65 years) and older (≥65 years) age groups. Patients completed self-report questionnaires prior to their next dose of CTX. RESULTS Overall, our findings suggest that compared to younger patients, older adults experience a lower or similar level of fatigue, decrements in energy, and sleep disturbance. However, it should be noted that both age groups experienced high occurrence rates and moderate to severe levels of all three symptoms. CONCLUSIONS Clinicians need to assess all oncology patients receiving CTX for these three symptoms. Future research needs to determine the biopsychosocial reasons that underlie these age-related differences in fatigue, decrements in energy, and sleep disturbance.

Abstract
OBJECTIVE Prior studies have documented disparities in short and long sleep duration, excessive daytime sleepiness, and insomnia by educational attainment and race/ethnicity separately. We examined both independent and interactive effects of these factors with a broader range of sleep indicators in a racially/ethnically diverse sample. METHODS We analyzed 2012 National Health Interview Survey data from 33,865 adults aged ≥18years. Sleep-related symptomatology included short sleep duration (≤6h), long sleep duration (≥9h), fatigue >3days, excessive daytime sleepiness, and insomnia. Bivariate analyses with chi-square tests and log-linear regression were performed. RESULTS The overall age-adjusted prevalence was 29.1% for short sleep duration, 8.5% for long sleep duration, 15.1% for fatigue, 12.6% for excessive daytime sleepiness, and 18.8% for insomnia. Educational attainment and race/ethnicity were independently related to the five sleep-related symptoms. Among Whites, the likelihood of most sleep indicators increased as educational attainment decreased; relationships varied for the other racial/ethnic groups. For short sleep duration, the educational attainment-by-race/ethnicity interaction effect was significant for African Americans (p<0.0001), Hispanics (p<0.0001), and Asians (p=0.0233) compared to Whites. For long sleep duration, the interaction was significant for Hispanics only (p=0.0003). CONCLUSIONS Our results demonstrate the importance of examining both educational attainment and race/ethnicity simultaneously to more fully understand disparities in sleep health. Increased understanding of the mechanisms linking sociodemographic factors to sleep health is needed to determine whether policies and programs to increase educational attainment may also reduce these disparities within an increasingly diverse population.

Insomnia in workers with delayed recovery from mild traumatic brain injury. Sleep Med 2015; 19:153-61. [PMID: 26358896 DOI: 10.1016/j.sleep.2015.05.014] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2015] [Revised: 05/25/2015] [Accepted: 05/29/2015] [Indexed: 11/24/2022]
Abstract
OBJECTIVE/BACKGROUND/AIM Insomnia has not been explored as it relates to recovery after mild traumatic brain injury (mTBI). We aimed to evaluate the prevalence of insomnia among Ontario workers with delayed recovery from mTBI, and its relationship with sociodemographic, TBI- and claim-related, behavioral, and clinical factors. PATIENTS/METHODS This was a cross-sectional study carried out over a period of 24 months in a large rehabilitation hospital in Ontario. To assess the prevalence of insomnia, we used the Insomnia Severity Index (ISI). Data were collected from standardized questionnaires, insurer records, and clinical assessment at the time of recruitment. Bivariate associations were calculated using the Spearman's correlation coefficient or analysis of variance. We established stepwise multivariate linear regression models of factors associated with insomnia. Additional analyses, including the assessment of the internal consistency of the ISI, were performed. RESULTS Of the 94 participants diagnosed with mTBI, clinical insomnia was reported by 69.2%. The mean age was 45.20 ± 9.94 years; 61.2% were men. No sex-related differences were observed in insomnia prevalence or severity. Insomnia was significantly associated with certain sociodemographic, claim-related, behavioral, and clinical variables. In the multivariable regression analysis, several determinants explained 53% of the insomnia variance. The internal consistency of the ISI, as measured by Cronbach's α, was 0.86. CONCLUSIONS Insomnia is common in persons with delayed recovery from mTBI, and is significantly associated with potentially modifiable clinical and nonclinical variables. Care of persons with brain injury requires greater attention with regard to the diagnosis and management of insomnia and associated disorders.

Abstract
Approximately 5% of older adults meet criteria for clinically significant insomnia disorders and 20% for sleep apnea syndromes. It is important to distinguish age-appropriate changes in sleep from clinically significant insomnia, with the latter having associated daytime impairments. Non-pharmacologic therapies, such as cognitive-behavioral therapy for insomnia, can be highly effective with sustained benefit. Pharmacologic therapies are also available, but may be associated with psychomotor effects. A high index of suspicion is crucial for effective diagnosis of sleep apnea because symptoms commonly noted in younger patients, such as obesity or loud snoring, may not be present in older patients.

Abstract
This study examined the use of self-care strategies to address difficulty sleeping among community-dwelling older adults. Data were collected from a series of 18 questionnaires administered to 195 rural African American and white older adults in North Carolina. Participants reported whether they had experienced difficulty sleeping and strategies used to respond to the symptom. The most widely used strategies included ignoring the symptom, staying in bed or resting, and praying. Herb and supplement use were not reported. Ethnicity, income, and education were associated with use of specific self-care strategies for sleep. This variation suggests that older adults may draw on cultural understandings to interpret the significance of difficulty sleeping and influence their use of self-care strategies, including complementary and alternative medicine use. This information may enable health care providers to communicate with the older patients about sleep difficulty strategies to minimize sleep problems.

Self-reported sleep disturbance is associated with lower CD4 count and 24-h urinary dopamine levels in ethnic minority women living with HIV. Psychoneuroendocrinology 2013; 38:2647-53. [PMID: 23850225 PMCID: PMC3812316 DOI: 10.1016/j.psyneuen.2013.06.022] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2013] [Revised: 06/12/2013] [Accepted: 06/17/2013] [Indexed: 11/24/2022]
Abstract
BACKGROUND Sleep disturbance is associated with dopamine dysregulation, which can negatively impact immune status. Individuals living with HIV experience more sleep difficulties, and poor sleep may compound immune decrements associated with HIV infection. Little research has examined associations between sleep, dopamine, and immune status (CD4 count) in individuals with HIV. As ethnic minority women living with HIV (WLWH) are at heightened risk for HIV disease progression, we related sleep reports to both CD4 count and dopamine levels in a cohort of ethnic minority WLWH. METHODS Participants were 139 low-income WLWH (ages 20-62; 78.3% African-American or Caribbean) who reported both overall sleep quality and sleep disturbance on the Pittsburgh sleep quality index (PSQI). CD4 count and HIV viral load were measured via morning peripheral venous blood samples, and concentrations of dopamine were measured via 24-h urine collection. Covariates included HIV viral load, length of time since HIV diagnosis, HAART adherence, perceived stress and depression. RESULTS After controlling for all covariates, greater sleep disturbance was associated with significantly lower CD4 count (β=-.20, p=.03) and lower levels of dopamine (β=-.25, p=.04). Poorer overall sleep quality was marginally associated with lower CD4 count (β=-.16, p=.08), and was not associated with dopamine. CONCLUSION Our analyses suggest that sleep disturbance is independently related with immune status and dopamine levels in WLWH. Lower levels of dopamine may indicate neuroendocrine dysregulation and may impact immune and health status. Results highlight sleep disturbance rather than overall sleep quality as potentially salient to neuroendocrine and immune status in ethnic minority WLWH.

Abstract
STUDY OBJECTIVES Growing evidence indicates sleep is a major public health issue. Race/ethnicity and socioeconomics may contribute to sleep problems. This study assessed whether sleep symptoms were more prevalent among minorities and/or the socioeconomically disadvantaged. DESIGN Cross-sectional. SETTING Epidemiologic survey. PATIENTS OR PARTICIPANTS 2007-2008 National Health and Nutrition Examination Survey (N = 4,081). INTERVENTIONS None. MEASUREMENTS AND RESULTS Sociodemographics included age, sex, race/ethnicity, marital status, and immigration. Socioeconomics included poverty, education, private insurance, and food insecurity. Sleep symptoms assessed were sleep latency > 30 min, difficulty falling asleep, sleep maintenance difficulties, early morning awakenings, non-restorative sleep, daytime sleepiness, snorting/gasping, and snoring. Decreased reported problems for most symptoms were found among minorities, immigrants, and lower education levels. In general, in fully adjusted models, long sleep latency was associated with female gender, being black/African American, lower education attainment, no private insurance, and food insecurity. Difficulty falling asleep, sleep maintenance difficulties, early morning awakenings, and non-restorative sleep were also associated with female gender and food insecurity. Daytime sleepiness was seen in female and divorced respondents. Snorting/gasping was more prevalent among male, other-Hispanic/Latino, and 9(th)- to 11(th)-grade-level respondents. Snoring was prevalent among male, other-Hispanic/Latino, less-educated, and food-insecure respondents. CONCLUSIONS Sleep symptoms were associated with multiple sociodemographic and economic factors, though these relationships differed by predictor and sleep outcome. Also, reports depended on question wording.

Abstract
Sleep duration in America has gradually declined over the last four decades and appears to have reached a plateau for the last six years, with recent studies reporting that the population's current average sleep duration is approximately 6 h. In this paper, we examine epidemiologic and community-based data on sleep complaints reported by American adults, specifically addressing the role of race/ethnicity in the subjective report of sleep problems. Subjective and objective findings indicate that black (throughout the text, we use the term black in lieu of African American for there are instances where we refer to individuals with self-ascribed race/ethnicity as black, African American, African, or Caribbean American; the term white is used to denote individuals of European descent). Americans have higher rates of long (≥9 h) and short (≤5 h) sleep than their white counterparts, and this may mediate a higher risk of cardiovascular disease, obesity and diabetes among blacks. In addition, studies show mixed results on sleep complaints among blacks compared to those among other ethnicities. This paper explores factors that may contribute to racial/ethnic differences in sleep including intra-ethnic variation, cultural biases, genetics and psychosocial factors.

Abstract
Studying sleep differences across different ethnic groups is not only important for our understanding of sleep but may lead to the development of new, culturally appropriate interventions. Perceptions of sleep quality, daytime sleepiness, and sleep cognitions (beliefs and attitudes) were investigated in a community sample of Caucasian Australians and Black immigrants currently resident in Australia from Zimbabwe (Black Zimbabwean) and Ghana (Black Ghanaian). A sample of a total of 176 participants including Caucasian Australian ( n = 58), Black Zimbabwean ( n = 59), and Black Ghanaian ( n = 59), aged between 18 and 60 years was surveyed. Groups were matched on age and gender, with a strong predominance of professional occupations in all groups in the final sample and no significant socio-economic status differences between groups. Participants completed the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Dysfunctional Beliefs and Attitudes about Sleep, and the Short Form-36 Health Survey. After matching participants on age, gender, and socio-economic status, no statistically significant group differences were found on sleep quality, daytime sleepiness, and physical health. However, significant group differences were found on beliefs and attitudes about sleep with Black Zimbabwean and Black Ghanaian participants, attributing sleep difficulties more to physical than psychological phenomena compared to Caucasian Australian participants.

Excessive Daytime Sleepiness among Hypertensive US-Born Blacks and Foreign-Born Blacks: Analysis of the CAATCH Data. Int J Hypertens 2013; 2013:852389.

Abstract
Background. Evidence shows that blacks exhibit greater daytime sleepiness compared with whites, based on the Epworth Sleepiness Scale. In addition, sleep complaints might differ based on individuals' country of origin. However, it is not clear whether individuals' country of origin has any influence on excessive daytime sleepiness (EDS). Study Objectives. We tested the hypothesis that US-born blacks would show a greater level of EDS compared with foreign-born blacks. The potential effects of sociodemographic and medical risk were also determined. Design. We used the Counseling African-Americans to Control Hypertension (CAATCH) data. CAATCH is a group randomized clinical trial that was conducted among 30 community healthcare centers in New York, yielding baseline data for 1,058 hypertensive black patients. Results. Results of univariate logistic regression analysis indicated that US-born blacks were nearly twice as likely as their foreign-born black counterparts to exhibit EDS (OR = 1.87, 95% CI: 1.30–2.68, P < 0.001). After adjusting for effects of age, sex, education, employment, body mass index, alcohol consumption, and smoking habit, US-born blacks were 69% more likely than their counterparts to exhibit EDS (OR = 1.69, 95% CI: 1.11–2.57, P < 0.01). Conclusion. Findings demonstrate the importance of considering individuals' country of origin, in addition to their race and ethnicity, when analyzing epidemiologic sleep data.

Abstract
Explore how social factors influence sleep, especially sleep-related beliefs and behaviors. Sleep complaints, sleep hygiene behaviors, and beliefs about sleep were studied in 65 black/African American and white/European American women. Differences were found for snoring and discrepancy between sleep duration and need. Sleep behaviors differed across groups for napping, methods for coping with sleep difficulties, and nonsleep behaviors in bed. Beliefs also distinguished groups, with differences in motivation for sleep and beliefs about sleep being important for health and functioning. These findings have important public health implications in terms of developing effective sleep education interventions that include consideration of cultural aspects.

Abstract
Previous research suggests that ethnic groups differ in the prevalence and severity of disordered sleep symptoms. This study used meta-analysis to determine the magnitude of ethnic differences between African Americans (AAs) and Caucasian Americans (CAs) in insomnia symptoms and sleep-disordered breathing (SDB). It also used moderator analyses to explore the variability in these effect sizes. Thirteen studies measuring insomnia symptoms and 10 studies measuring SDB met inclusion criteria and represented thousands of adult AAs and CAs. Results indicate AAs have a higher prevalence and greater severity of SDB, but CAs report more insomnia symptoms. These results indicate a need for a multi-ethnic approach to the assessment and treatment of sleep disorders.

Abstract
The authors of this investigation sought to examine changes in the sleep quality of older women over time and to determine whether dimensions of psychological well-being, health (subjective health and number of illnesses), and psychological distress (depression and anxiety) predict these changes. A secondary analysis was conducted with a longitudinal sample of aging women (Kwan, Love, Ryff, & Essex, 2003). Of 518 community-dwelling older women in the parent study, 115 women (baseline M age = 67 years, SD = 7.18) with data at baseline, 8 years, and 10 years were used for this investigation. Participants completed self-administered questionnaires and participated in in-home interviews and observations. Growth curve modeling was used to examine the overall linear trajectories of sleep quality. Growth mixture modeling was used to examine whether there were different patterns of change in sleep quality over time and to examine baseline predictors of each pattern. Sleep quality declined over time but not for all women. Two distinctly different sleep patterns emerged: good but declining sleep quality and disrupted sleep quality. Higher psychological well-being (positive relations with others, environmental mastery, personal growth, purpose in life, and self-acceptance), fewer illnesses, and lower depression scores at baseline predicted reduced odds for membership in the disrupted sleep group. Future research is needed to examine whether interventions focused on maintaining or enhancing psychological well-being could minimize later life declines in sleep quality.

Abstract
BACKGROUND Insomnia and obstructive sleep apnea (OSA) are the two most common sleep disorders. Studies have shown that complaints of insomnia are prevalent among sleep clinic patients evaluated for OSA. Less is known about the gender and ethnic variations in this association. OBJECTIVES This paper aims to study the influence of gender and ethnicity in the prevalence of insomnia in patients with OSA and explore the association between these two disorders with an emphasis on psychophysiologic insomnia. METHODS AND MEASUREMENTS We reviewed case files, including self-reported questionnaires and polysomnography studies of 300 OSA patients [apnea-hypopnea index (AHI) of >10] from three ethnic groups--Caucasian, Hispanic, and African American, 50 patients each, male and female, seen at a tertiary care county hospital adult sleep center. Self-reported insomnia was classified as sleep onset insomnia, sleep maintenance insomnia, or insomnia with early morning awakening. Psychophysiologic insomnia was documented if the patient reported two of the following five symptoms: racing thoughts when trying to sleep, increased muscle tension when trying to sleep, fear of being unable to sleep, fear of being unable to fall back to sleep after waking up, and lying in bed worrying. Fischer exact tests for each contingency table were run using SPSS. RESULTS Among OSA patients, women were older, had higher body mass index, and lower AHI at the time of diagnosis, compared to men. Insomnia was more prevalent among patients with OSA (84%) than the reported 30% among general adult population. Sleep onset insomnia was reported more frequently by women (62%) than men (53%) (p = 0.03). Similarly self-reported psychophysiologic insomnia also showed a female preponderance (53% vs. 45%, p = 0.03). Caucasian women had the highest rate of self-reported sleep maintenance insomnia (80%). Hispanic women are more likely to complain of symptoms suggestive of psychophysiologic insomnia (58%). CONCLUSIONS There is a higher prevalence of insomnia in OSA patients. Ethnicity and gender possibly exhibit a complex and significant influence on the reported subtype of insomnia. Further larger studies may help confirm, as well as clarify, mechanisms that underlie the ethnic and gender differences that we have noted.

Abstract
OBJECTIVES Lower socioeconomic status is associated with short or long sleep duration and sleep disturbance (e.g., sleep apnea), which are all related to increased mortality risk. General sleep complaints, however, which may better approximate symptoms as they are experienced, have not been examined in a large population sample. METHODS Sample consisted of n=159,856 participants from the Behavioral Risk Factor Surveillance System, representing 36 states/regions across the US. Sleep complaints were measured with a telephone survey item that assessed "trouble falling asleep," "staying asleep" or "sleeping too much." Data analysis utilized hierarchical logistic regression and Rao-Schott chi(2). RESULTS Asian respondents reported the least complaints, and Hispanic/Latino and Black/African-American individuals reported fewer complaints than Whites. Lower income and educational attainment was associated with more sleep complaints. Employment was associated with less sleep complaints and unemployment with more. Married individuals reported the least sleep complaints. Significant interactions with race/ethnicity indicate that the relationship between sleep complaints and marital status, income and employment differs among groups for men, and the relationship with education differs among groups for women. CONCLUSIONS Rates of sleep complaints in African-American, Hispanic/Latino and Asian/Other groups were similar to Whites. Lower socioeconomic status was associated with higher rates of sleep complaint.

Abstract
OBJECTIVE Nocturnal awakenings are one of the most prevalent sleep disturbances in the general population. Little is known, however, about the frequency of these episodes and how difficulty resuming sleep once awakened affects subjective sleep quality and quantity. METHOD This is a cross-sectional telephone study with a representative sample consisting of 8937 non-institutionalized individuals aged 18 or over living in Texas, New York and California. The interviews included questions on sleeping habits, health, sleep and mental disorders. Nocturnal awakenings were evaluated according to their frequency per week and per night, as well as their duration. RESULTS A total of 35.5% of the sample reported awakening at least three nights per week. Of this 35.5%, 43% (15.2% of the total sample) reported difficulty resuming sleep once awakened. More than 80% of subjects with insomnia symptoms (difficulty initiating or maintaining sleep or non-restorative sleep) also had nocturnal awakenings. Difficulty resuming sleep was associated with subjective shorter sleep duration, poorer sleep quality, greater daytime impairment, greater consultations for sleep disturbances and greater likelihood of receiving a sleep medication. CONCLUSIONS Nocturnal awakenings disrupt the sleep of about one-third of the general population. Using difficulty resuming sleep identifies individuals with significant daytime impairment who are most likely to seek medical help for their sleep disturbances. In the absence of other insomnia symptoms, nocturnal awakenings alone are unlikely to be associated with daytime impairments.

Abstract
Obstructive sleep apnea (OSA) is a prevalent sleep disorder that disproportionately affects blacks. While clinical and epidemiologic data indicate intraethnic differences in several medical diseases, little is known about whether OSA symptoms differ within the black ethnic group. We estimated the rate of OSA symptoms in a community-based sample of Caribbean-born black men and women. We also ascertained which sociodemographic and/or medical factors were associated with OSA risk. A total of 554 patients (mean age = 48.17 +/- 16.75 years) participated in the study; 55% were women. Data were collected in four primary-care clinics in Brooklyn, NY. A health educator explained the purpose of the study to interested patients and assisted consenting participants in completing questionnaires, which required 15 min to complete. Participants reporting habitual snoring, excessive daytime sleepiness, and sleep fragmentation were considered at high OSA risk. The rate of OSA symptoms was: snoring (45%), excessive daytime sleepiness (33%), and difficulty maintaining sleep (34%). Many reported falling asleep while watching television (47%) or while driving (14%). Based on logistic regression analysis, a history of heart disease was the most important predictor of the likelihood of expressing OSA symptoms, with a corresponding multivariate-adjusted odds ratio of 11 (95% confidence interval = 3.03-40.63). Findings suggest the need to investigate whether Caribbean-born blacks are at greater risk for developing OSA than African Americans and whites. Caribbean-born blacks with a history of heart disease should be a prime target for interventions that promote adequate screening and timely OSA diagnosis.
