The association of acculturative stress with self-reported sleep disturbance and sleep duration among Asian Americans

Prospective Associations of COVID-19 Pandemic-Related Stressful Events With Mental and Sleep Health in a Population-Based Cohort Study of Adults With SARS-CoV-2 Infection

COVID-19 pandemic-related stressful events are associated with adverse mental health outcomes; however, prior evidence is limited due to cross-sectional designs or convenience sampling, with little focus on sleep health. We examined prospective associations of COVID-19 pandemic-related stressful events at baseline with mental health and sleep health at follow-up using a population-based cohort of Michigan adults with PCR-confirmed COVID-19. We measured COVID-19-related stressful events using the 6-item Epidemic-Pandemic Impacts Inventory (EPII), designed to assess pandemic impacts across personal and social life domains. We conducted (1) modified Poisson regression with robust standard errors for depressive symptoms, anxiety symptoms, COVID-19-related post-traumatic stress disorder (PTSD) symptoms, and poor-to-very poor sleep quality and (2) multinomial logistic regression for sleep duration (< 6, 6-9, > 9 h). We adjusted for sociodemographic, clinical, and survey factors. Our analytic samples were n = 3523 for mental health and n = 3191 for sleep health. Each additional COVID-19-related stressful event reported was associated with a higher risk of reporting depressive symptoms (adjusted risk ratio [aRR]: 1.22, 95% confidence interval [CI]:1.14-1.30), anxiety symptoms (aRR: 1.20, 95% CI: 1.14-1.27) and COVID-19-related PTSD symptoms (aRR: 1.31, 95% CI: 1.22-1.42). Each additional COVID-19-related stressful event reported was also associated with a 1.13 times higher risk of reporting poor-to-very poor sleep quality (95% CI: 1.07-1.20). In the multinomial logistic regression models, stressful events were associated with a 1.21 (95% CI: 1.06-1.37) higher risk of sleeping < 6 h relative to sleeping 6-9 h. We need social support services and programs to improve psychological and behavioural responses to COVID-19-related stressful events.

How Acculturation Shapes Sleep in Thai Women in the United States During Menopausal Transition: A Mediation and Moderation Analysis

INTRODUCTION

This study examines acculturation's impact on sleep quality, efficiency, and obstructive sleep apnea (OSA) risk among Thai women in the United States transitioning through menopause.

METHODOLOGY

This cross-sectional descriptive study recruited 120 Thai women aged 40 to 65. Questionnaires assessed sleep quality (Pittsburgh Sleep Quality Index [PSQI]), OSA risk (Berlin), menopausal symptoms (Menopause Rating), acculturation (Suinn-Lew Asian Self-Identity Scale), and anxiety (Patient-Reported Outcome Measurement Information System). Data were analyzed using bivariate correlations, multivariable regression, and mediation/moderation analyses.

RESULTS

Mean age was 51.53 (SD = 7.73) years. Most were good sleepers (PSQI <5: 80.83%) and 14.17% at high risk of OSA. Acculturation was associated with better sleep quality (B = -1.086, p = .027) and higher sleep efficiency (B = 2.425, p = .021). Mediation analysis indicated that length of stay in the United States indirectly affected sleep quality (B = -0.022, p = .026) and efficiency (B = 0.051, p = .018) via acculturation.

DISCUSSION

Acculturation significantly affects sleep among Thai women; higher acculturation correlates with better sleep quality and efficiency. Acculturation did not affect OSA risk, suggesting context-specific influences that may benefit sleep through increased social integration. Future research should explore underlying mechanisms in immigrant populations.

Acculturation is associated with 12-month adherence to combined MVPA and sedentary behavior guidelines in a sample of midlife and older Latino/a adults: findings from the COMPASS physical activity trial

BACKGROUND

Although some studies have shown that greater acculturation is associated with an increased risk of cardiovascular disease (CVD) among Latino/a adults, the relationship between acculturation and modifiable health behaviors in older Latino/a adults living in the United States (US) remains underexplored. This secondary analysis of the COMPASS physical activity trial explored the relationship between acculturation and adherence to combined movement behavior guidelines for moderate to vigorous physical activity (MVPA) and sedentary behavior guidelines at 12 months among 245 midlife and older Latino/a adults from the San Francisco Bay Area.

METHODS

Baseline acculturation was measured using the Short Acculturation Scale for Hispanics, yielding a total score and three subscales on a 5-point Likert scale, higher scores represented higher acculturation. MVPA was evaluated via the Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire, while sedentary behavior was measured using a validated 1-week recall survey. We employed logistic regression to analyze linear and non-linear associations between acculturation and adherence to the combined MVPA (≥ 150 min/wk) and sedentary behavior (< 8 h/day) movement behavior guidelines, adjusting for baseline MVPA and sedentary behavior, intervention arm, gender, income, body mass index, education, and years in the US.

RESULTS

At baseline, 6.4% adhered to combined MVPA and sedentary behavior guidelines, with the prevalence of adherence rising to 30.2% at 12 months. Each one-point increase in language use acculturation subscale score was linked to 1.7 times greater adherence (p = 0.01) at 12 months. A similar pattern was observed when acculturation was operationalized as a binary variable (p = 0.03). For the summary acculturation score, participants with higher acculturation had 2.6 times higher odds of adhering to guidelines at 12 months compared to those with lower acculturation (p = 0.04).

CONCLUSIONS

Higher acculturation was associated with a higher odds of 12 month adherence to MVPA and sedentary behavior guidelines among a sample of older Latino/a adults. Results underscore the importance of incorporating acculturation into behavioral trialsand the need to tailor physical activity interventions for Latino/a older adults with lower acculturation.

Investigation and analysis of sleep and mental health status among MEFCs

Objective

To investigate the sleep status and mental health of migrants elderly who followed their children (MEFC) and analyze the influencing factors.

Methods

A total of 583 MEFCs were surveyed using a general demographic questionnaire, the Pittsburgh Sleep Quality Index (PSQI) scale, and the Symptom Checklist 90 (SCL90) scale.

Results

The mean PSQI score for MEFCs was 6.98 ± 0.17, and the average SCL90 score was 64.06 ± 2.03. Multiple linear regression analysis indicated that health status and adaptation to the migration destination were associated with PSQI scores (P < 0.05). Health status, adaptation to the migration destination, and family harmony were associated with SCL90 scores (P < 0.05). The association coefficient between the total PSQI and SCL90 scores was r=0.462 (P < 0.05).

Conclusion

The sleep and mental health of MEFCs were at a normal level. Health status and adaptation influenced sleep status, while health status, adaptation, and family harmony impacted mental health. However, the association between mental health and sleep status was weak.

Heterogeneities in sleep duration and quality among U.S. immigrants from different racial and ethnic backgrounds

OBJECTIVES

Sleep plays an essential role in well-being. Although U.S. immigrants are considerably growing, few studies have examined sleep in this diverse population, particularly those from Asian backgrounds. It is also unclear how sleep differs by the length of residence across immigrant groups. In this study, we examined the relationships among race/ethnicity, length of residence, and sleep using a nationally representative cohort of U.S. immigrants.

METHODS

We analyzed data from the 2013-2018 National Health Interview Survey. The sample (N = 27,761; 14% ≥65 years old) included foreign-born adults from the following racial/ethnic backgrounds: non-Hispanic White, non-Hispanic Black, Asian (Chinese, Filipino, Asian Indian), and Hispanic/Latino. Length of residence was categorized as <5, 5-9, 10-14, and ≥15years. Sleep was assessed with self-reported sleep duration (normal, short, and long) and poor sleep quality (trouble falling asleep, trouble staying asleep, and waking up unrested).

RESULTS

Filipino and Hispanic/Latino immigrants reported the highest prevalence of short (41.8%) and long (7.0%) sleep, respectively. Non-Hispanic White immigrants had the highest prevalence rate across all three poor sleep quality measures (range 17.7-41.5%). Length of residence ≥15years was significantly associated with worse sleep, and it moderated White-Asian differences in sleep quality. Immigrants from different racial/ethnic groups showed variations in sleep patterns as they resided longer in the US.

CONCLUSIONS

Immigrants exhibited substantial heterogeneities in sleep. Future research should investigate the contributing factors to the variations in their sleep patterns, both between groups and within the same group of immigrants, in order to inform tailored interventions.

Eyes Wide Open: Sleep as a Potential Contributor to Racial and Ethnic Disparities in Cancer

U.S. racial and ethnic minoritized groups face disproportionate cancer burdens compared to White Americans. Investigating modifiable factors, such as sleep, that are socially patterned and inequitably distributed by race and ethnicity may advance understanding of cancer disparities and provide intervention opportunities. Emerging data suggest poor sleep health is associated with cancer. Yet, its contribution to racial and ethnic cancer disparities is understudied. In this narrative review, we explored the sleep-cancer relation through a disparities lens. We (i) summarized literature reporting on associations between sleep and cancer among racial and ethnic minority populations; (ii) examined potential sleep-cancer mechanisms; and (iii) discussed future directions. We identified five studies reporting on sleep-cancer associations among minoritized groups. Poor sleep health was associated with aggressive breast cancer among Black women, increased breast cancer risk among Asian women, and increased risk of breast and total cancer among Hispanic/Latinx Americans. Sleep and cancer disparities have similar socioeconomic and behavioral determinants, suggesting racial and ethnic minoritized groups may be vulnerable to poor sleep health and its adverse health impacts. Evidence indicates that the sleep-cancer disparities relation is an emerging, but important area of research that warrants further investigation, as sleep may be an avenue for reducing cancer disparities.

Obesity Disparities Among Adult Single-Race and Multiracial Asian and Pacific Islander Populations

Importance

Despite increasing numbers of multiracial individuals, they are often excluded in studies or aggregated within larger race and ethnicity groups due to small sample sizes.

Objective

To examine disparities in the prevalence of obesity among single-race and multiracial Asian and Pacific Islander individuals compared with non-Hispanic White (hereafter, White) individuals.

Design, Setting, and Participants

This cross-sectional study used electronic health record (EHR) data linked to social determinants of health and health behavior data for adult (age ≥18 years) members of 2 large health care systems in California and Hawai'i who had at least 1 ambulatory visit to a primary care practitioner between January 1, 2006, and December 31, 2018. Data were analyzed from October 31, 2022, to July 31, 2023.

Exposure

Self-identified race and ethnicity provided in the EHR as a single-race category (Asian Indian, Chinese, Filipino, Japanese, Native Hawaiian only, Other Pacific Islander, or White) or a multiracial category (Asian and Pacific Islander; Asian, Pacific Islander, and White; Asian and White; or Pacific Islander and White).

Main Outcomes and Measures

The main outcome was obesity (body mass index [BMI] ≥30.0), based on last measured height and weight from the EHR. Logistic regression was used to examine the association between race and ethnicity and odds of obesity.

Results

A total of 5229 individuals (3055 [58.4%] male; mean [SD] age, 70.73 [11.51] years) were examined, of whom 444 (8.5%) were Asian Indian; 1091 (20.9%), Chinese; 483 (9.2%), Filipino; 666 (12.7%), Japanese; 91 (1.7%), Native Hawaiian; 95 (1.8%), Other Pacific Islander; and 888 (17.0%), White. The percentages of individuals who identified as multiracial were as follows: 417 (8.0%) were Asian and Pacific Islander; 392 (7.5%), Asian, Pacific Islander, and White; 248 (4.7%), Asian and White; and 414 (7.9%), Pacific Islander and White. A total of 1333 participants (25.5%) were classified as having obesity based on standard BMI criteria. Obesity was highest among people who identified as Asian, Pacific Islander, and White (204 of 392 [52.0%]) followed by those who identified as Other Pacific Islander (47 of 95 [49.5%]), Native Hawaiian (44 of 91 [48.4%]), and Pacific Islander and White (186 of 414 [44.9%]). After accounting for demographic, socioeconomic, and health behavior factors, people who identified as Asian, Pacific Islander, and White (odds ratio [OR], 1.80; 95% CI, 1.37-2.38) or Pacific Islander and White (OR, 1.55; 95% CI, 1.18-2.04) had increased odds of obesity compared with White individuals. All single-race Asian groups had lower odds of obesity compared with White individuals: Asian Indian (OR, 0.29; 95% CI, 0.20-0.40), Chinese (OR, 0.22; 95% CI, 0.17-0.29), Filipino (OR, 0.46; 95% CI, 0.35-0.62), and Japanese (OR, 0.38, 95% CI, 0.29-0.50).

Conclusions and Relevance

In this study, multiracial Asian and Pacific Islander individuals had an increased prevalence of obesity compared with many of their single-race counterparts. As the number of multiracial individuals increases, it will be important for clinical and public health systems to track disparities in these populations.

A Data-Driven Approach to Identify the Predictors of Perceived Health Status Among Chinese and Korean Americans

Asian Americans are the country's fastest-growing racial group, and several studies have focused on the health outcomes of Asian Americans, including perceived health status. Perceived health status provides a summarized view of the health of populations for diverse domains, such as the psychological, social, and behavioral aspects. Given its multifaceted nature, perceived health status should be carefully approached when examining any variables' influence because it results from interactions among many variables. A data-driven approach using machine learning provides an effective way to discover new insights when there are complex interactions among multiple variables. To date, there are not many studies available that use machine learning to examine the effects of diverse variables on the perceived health status of Chinese and Korean Americans. This study aims to develop and evaluate three prediction models using logistic regression, random forest, and support vector machines to find the predictors of perceived health status among Chinese and Korean Americans from survey data. The prediction models identified specific predictors of perceived health status. These predictors can be utilized when planning for effective interventions for the better health outcomes of Chinese and Korean Americans.

Mind-body-medicine in oncology-from patient needs to tailored programs and interventions: a cross-sectional study

Introduction

National and international guidelines recommend early integration of evidence-based multimodal interventions and programs, especially with a focus on relaxation techniques and other Mind-Body-based methods to maintain the quality of life of oncology patients, improve treatment tolerability, and promote healthy lifestyle behaviors. Consequently, we aim to understand what drives patients and how they navigate integrative medicine to best advise them. This study aimed to detect possible topics of particular interest to patients and identify the patient groups that could benefit most from further programs. Furthermore, we aimed to investigate if patients are open-minded toward integrative oncology concepts and learn about their motivational level to maintain or change behavior.

Methods

Between August 2019 and October 2020 we surveyed patients undergoing oncological therapy in a university oncological outpatient center using a custom-developed questionnaire based on established Mind-Body Medicine concepts.

Results

We included 294 patients with various cancers. More than half reported problems sleeping through (61%) and 42% felt stressed frequently, invariably rating this as detrimental to their health. Moreover, a slight majority (52%) felt physically limited due to their disease and only 30% performed defined exercise programs. Women were significantly more likely to feel stressed and reported with alarming frequency that they often feel "everything was up to them." The 40-65-year-olds reported significantly less restful sleep, more stress and were more dissatisfied with their situation. However, this group already used natural remedies most frequently and was most often motivated to use relaxation techniques in the next 6 months. The lower the perceived individual energy level (EL), the less frequently patients did sport, the more frequently they felt their disease impaired their activity, mostly feeling stressed and tense. We also found significant associations between negative emotions/thoughts and the variables "sleep," "use of relaxation techniques," "personal stress perception," and "successful lifestyle modification."

Conclusion

Mind-Body programs that focus on patient's individual resources, with tools to explore impairing patterns of self-perception and cognitive biases, can be a valuable resource for oncology patients and should therefore be part of an integrative medical treatment concept.

Association of long-term exposure to air pollution with chronic sleep deprivation in South Korea: A community-level longitudinal study, 2008-2018

BACKGROUND AND OBJECTIVE

Although there are many findings about the effects of fine particulate matter (PM_2.5) and sleep deprivation on health respectively, the association between PM_2.5 and chronic sleep deprivation has rarely been investigated. Thus, we aimed to investigate this association using a nationwide survey in South Korea.

METHOD

We examined the association between long-term exposure to PM_2.5 and chronic sleep deprivation using a national cross-sectional health survey covering the entire 226 districts in inland South Korea from 2008 to 2018, with a machine learning-based national air pollution prediction model with 1 km² spatial resolution.

RESULTS

Chronic sleep deprivation was positively associated with PM_2.5 in the total population (odds ratio (OR): 1.09, 95% confidence interval (CI): 1.05-1.13) and sub-population (low, middle, high population density areas with OR: 1.127, 1.09, and 1.059, respectively). The association was consistently observed in both sexes (males with OR: 1.09, females with OR: 1.09)) and was more pronounced in the elderly population (OR: 1.12) than in the middle-aged (OR: 1.07) and young (OR: 1.09) populations.

CONCLUSIONS

Our results are consistent with the hypothesis regarding the relationship between long-term PM_2.5 exposure and chronic sleep deprivation, and the study provides quantitative evidence for public health interventions to improve air quality that can affect chronic sleep conditions.

A systematic review of acculturation and sleep health among adult immigrants in the United States

The United States (US) has more immigrants than any other country in the world, with an estimated 44 million non-US-born individuals residing in the country as of 2018. Previous studies have linked US acculturation to both positive and negative health outcomes, including sleep. However, the relationship between US acculturation and sleep health is not well understood. This systematic review aims to identify and synthesize scientific studies on acculturation and sleep health among adult immigrants in the US. A systematic search of the literature was performed in PubMed, Ovid MEDLINE, and Web of Science in 2021 and 2022 with no date limiters. Quantitative studies published anytime in a peer-reviewed journal in English among an adult immigrant population with an explicit measure of acculturation and a sleep health dimension, sleep disorder, or daytime sleepiness measure were considered for inclusion. The initial literature search yielded 804 articles for review; after removing duplicates, applying inclusion and exclusion criteria, and searching reference lists, 38 total articles were included. We found consistent evidence that acculturative stress was associated with worse sleep quality/continuity, daytime sleepiness, and sleep disorders. However, we discovered limited consensus on the association of acculturation scales and acculturation proxy measures with sleep. Our review demonstrated that compared to US-born adult populations, there is a high prevalence of adverse sleep health among immigrant populations, and acculturation likely plays an important role in shaping this disparity, particularly through acculturative stress.

Oral Microbiome, Mental Health, and Sleep Outcomes During the COVID-19 Pandemic: An Observational Study in Chinese and Korean American Immigrants

COVID-19 is a systemic disease whose effects are not limited to the respiratory system. The oral microbiome (OM)-brain axis is of growing interest in understanding the broader, neuropsychiatric, impacts of the COVID-19 pandemic through a systems biology lens. In this context, mental health and sleep disturbance are often reported by Asian Americans. In a cross-sectional observational study design, we examined the associations of the oral microbiome with mental health among Asian Americans during the COVID-19 pandemic (between November 2020 and April 2021). Participants (n = 20) were adult Chinese and Korean American immigrants in Atlanta, Georgia, and primarily born outside the United States (60%) with a mean age of 34.8 years ±14 (standard deviation). Participants reported depressive symptoms, anxiety, and sleep disturbance, as measured by standard questionnaires. The OM was characterized by 16S rRNA V3-V4 gene using saliva. Depressive symptoms and anxiety were reported by 60% (n = 12) of participants, whereas 35% (n = 7) reported sleep disturbance. The α-diversity was significantly associated with depressive symptoms, and marginally with anxiety. Participants with depressive symptoms and anxiety had enriched Rothia and Scardovia, respectively, whereas those without symptoms had enriched Fusobacterium. Individuals with sleep disturbance had enriched Kingella. In conclusion, this study suggests significant associations of the OM diversity with certain mental health dimensions such as depressive symptoms and anxiety. Specific taxa were associated with these symptoms. The present observations in a modest sample size suggest the possible relevance of the OM-brain axis in studies of mental health during COVID-19.

Sleep disparities in Asian Americans: a comprehensive review

STUDY OBJECTIVES

This review summarizes race-based sleep health disparities between Asian Americans and other American racial groups and compares sleep outcomes between Asian American subgroups disaggregated by ethnicity and ancestral national origin. The study identifies gaps in the existing literature, analyzes barriers to studying Asian American sleep, and recommends topics for future research.

METHODS

A PubMed review of research on adult Asian American sleep was conducted. The articles included utilized actigraphy, polysomnography, and questionnaires to gather sleep health metrics. Information from these articles included data on sleep duration, sleep quality, sleep disturbances, and sleep disorders.

RESULTS

Most aggregated studies find Asian American adults experiencing lower sleep duration and poorer sleep quality compared to non-Hispanic White Americans and comparable or slightly higher sleep duration compared to Black Americans. Within Asian Americans, first-generation immigrants report better sleep quality than subsequent generations. East Asian Americans may experience better sleep outcomes compared to Southeast Asian Americans. Obstructive sleep apnea is critically underreported in South Asian Americans.

CONCLUSIONS

Significantly more research is required in Asian American sleep disparities, specifically in South and Southeast Asian Americans. Sleep disparities between Asian Americans and other racial groups are impacted by perceived discrimination, poor mental health, and cultural attitudes toward sleep. The observed within-group disparities of Asian American sleep may be attributed to socioeconomic status and generational status/acculturation. Existing barriers to research include the model minority myth and lack of disaggregated racial sleep data.

The Mediating Role of Sleep Disturbance on the Association Between Stress and Self-Rated Health Among Chinese and Korean Immigrant Americans

INTRODUCTION

Disturbed sleep may be a factor that links stress with poor health, especially among groups experiencing high levels of stress caused by racial and ethnic minority and nativity status. The objective of this study was to describe the potential mediating role of sleep disturbance in the associations between various types of stress and self-rated health among Chinese and Korean Americans.

METHODS

Our cross-sectional study consisted of 400 Chinese and Korean immigrants aged 50 to 75 years recruited from August 2018 through June 2020 from physicians' clinics in the Baltimore-Washington, DC, metropolitan area. We used the Patient Reported Outcomes Measurement Information System (PROMIS) short-form questionnaire to measure sleep disturbance. Linear regression analyses examined associations between 3 types of stress (acculturative stress, perceived stress, and distress) and self-rated health, accounting for demographic, socioeconomic, and health insurance factors. The Karlson-Holm-Breen method was used to estimate the total and direct effects of stresses on self-rated health and the indirect effects of stresses on health through sleep disturbance.

RESULTS

Greater acculturative stress (β = 0.08; 95% CI, 0.01-0.14), perceived stress (β = 0.05; 95% CI, 0.03-0.08), and distress (β = 0.09; 95% CI, 0.05-0.13) were all associated with poorer self-rated health. Sleep disturbance was a partial mediator, with sleep disturbance accounting for 21.7%, 14.9%, and 18.7% of the associations between acculturative stress, perceived stress, and distress and self-rated health, respectively.

CONCLUSION

Because sleep disturbance partially mediates the associations between stress and poor self-rated health, future interventions and research may consider mitigating sleep disturbances and stress among racial and ethnic minority populations to address health disparities.

Leading Predictors of COVID-19-Related Poor Mental Health in Adult Asian Indians: An Application of Extreme Gradient Boosting and Shapley Additive Explanations

During the COVID-19 pandemic, an increase in poor mental health among Asian Indians was observed in the United States. However, the leading predictors of poor mental health during the COVID-19 pandemic in Asian Indians remained unknown. A cross-sectional online survey was administered to self-identified Asian Indians aged 18 and older (N = 289). Survey collected information on demographic and socio-economic characteristics and the COVID-19 burden. Two novel machine learning techniques-eXtreme Gradient Boosting and Shapley Additive exPlanations (SHAP) were used to identify the leading predictors and explain their associations with poor mental health. A majority of the study participants were female (65.1%), below 50 years of age (73.3%), and had income ≥ $75,000 (81.0%). The six leading predictors of poor mental health among Asian Indians were sleep disturbance, age, general health, income, wearing a mask, and self-reported discrimination. SHAP plots indicated that higher age, wearing a mask, and maintaining social distancing all the time were negatively associated with poor mental health while having sleep disturbance and imputed income levels were positively associated with poor mental health. The model performance metrics indicated high accuracy (0.77), precision (0.78), F1 score (0.77), recall (0.77), and AUROC (0.87). Nearly one in two adults reported poor mental health, and one in five reported sleep disturbance. Findings from our study suggest a paradoxical relationship between income and poor mental health; further studies are needed to confirm our study findings. Sleep disturbance and perceived discrimination can be targeted through tailored intervention to reduce the risk of poor mental health in Asian Indians.

Experiences of Sleep Problems Among Older Korean Immigrants

Despite poor sleep among older adults, little is known about the sleep habits of older immigrants living in the United States. The current pragmatic qualitative descriptive study explored sleep among older Korean immigrants, using a focus group with six participants and individual phone interviews with 22 Korean immigrants aged ≥60 years. Transcripts were coded to identify underlying themes. Several thematic categories were identified under six domains: daytime function, getting ready for bed, falling asleep, awakenings during sleep, going back to sleep, and seeking advice from peers. Unhealthy sleep behaviors were found during daytime and bedtime, particularly among those who were retired/unemployed or living alone. Seeking advice from peers was common but none of the advice helped participants sleep. Sleep education programs in Korean-speaking communities can be used to target those who are socially isolated and may benefit older Korean immigrants with sleep difficulties.
