“…In most studies in other countries, lower income or lower educational attainment was associated with a lower prevalence of depression treatment, or there was no association [22][23][24][25][26]. In the present study, however, the lowestincome quintile showed the highest rate of depression treatment among respondents with psychological distress.…”
Objectives Psychological distress is a health issue of critical importance, especially in people of working age in developed countries, including Japan. This study examined the relationships of income and employment arrangement with psychological distress and treatment of depression in a national sample of Japanese adults. Methods Data for 10,959 men and 11,655 women 25-59 years of age, obtained from the Comprehensive Survey of the Living Conditions of People on Health and Welfare in 2007, were examined. Health outcomes were psychological distress measured by the Japanese version of the K6, subjective complaints and medical treatment of depression. Explanatory variables included marital status, employment arrangement, and household income. The relationships between health outcomes and explanatory variables were examined using multiple logistic regression analyses. Results Lower income and unemployment were associated with a higher prevalence of psychological distress and treatment of depression. The association between psychological distress and income showed a threshold: the lowest income quintile had an especially high prevalence, while other quintiles had similar prevalences. The prevalence of depression treatment in those with psychological distress was significantly lower in the highest income quintile than in all the other income groups, and the prevalence was also significantly lower in employed than in unemployed respondents. Conclusions This study showed clear relationships of lower income and unemployment with psychological distress and depression treatment. It has been suggested that people with higher socioeconomic status and full-time work may be reluctant to consult professionals and receive medical treatment, despite their psychological distress. Comprehensive mental health interventions are required to prevent psychological distress in all socioeconomic strata of the population.

“…The rate of mental health service use for depression treatment by the KA elders in our study was found to be seeking professional help among elders with clinically significant depression in the Washington Heights-Inwood Columbia Aging Project (Grunebaum, Oquendo, & Manly, 2008) or the antidepressant treatment rate of 35.7% among depressed elderly participants in the Cache County study (Steffens, Fisher, Langa, Potter, & Plassman, 2009). Though scarce, a few available national data indicate Asian American elders as one of the least likely ethnic groups to utilize mental health services.…”
Background
Korean Americans (KA) comprise the fourth largest Asian-American subgroup, with a population estimated at nearly 1.7 million, and the vast majority (up to 85%) of KA elders attends ethnic churches. Despite the rapid increase of the KA elderly population, data on mental health service utilization among KA elders are scarce.
Method
Based on a cluster sampling method, the Memory and Aging Study among Koreans in Maryland (MASK-MD) recruited and assessed 630 KA elders (mean age: 70.9 ± 6.1 years; 68.9% female) in KA churches for depression, dementia, and level of mental health service utilization. The Korean versions of the Patient Health Questionnaire (PHQ-9K) and Mini-mental Status Examination (MMSE-KC) were administered by trained community health workers.
Results
Of the 630 participants, 23.2% and 7.3% had PHQ-9 scores of 5 (‘mild depression’) or above and 10 or above (‘clinical depression’), respectively. In addition, 7.0% scored below the age- and education-specific cutoff values for probable dementia based on the MMSE-KC. Of the 92 participants with ‘clinical depression’ or having thoughts of death or self-injury, only 16 (17%) reported utilizing mental health services. Likewise, of 56 participants with probable dementia, only 3 (7.3%) sought treatment from a health care provider.
Conclusion
The prevalence of depression and cognitive impairment are high in community-dwelling KA elders attending KA churches, but the rate of mental health service utilization among depressed or cognitively impaired Korean elders is low. Further research is warranted to identify barriers to and strategies for adequate mental health care for Korean immigrant elders.
“…A higher z-score indicates better cognitive performance. A more complete description of the neuropsychological test battery and the cognitive scores can be found in previous publications (Stern et al ., 1992; Manly et al ., 2005; Grunebaum et al ., 2008; Salthouse, 2011; Zahodne et al ., 2014). …”
Objective
This study aimed to examine the association between self-reported sleep problems and cognitive decline in community-dwelling older people. We hypothesized that daytime somnolence predicts subsequent cognitive decline.
Methods
This is a longitudinal study in a 3.2-year follow-up, with 18-month intervals. The setting is the Washington Heights-Inwood Community Aging Project. There were 1098 participants, who were over 65 years old and recruited from the community.
Sleep problems were estimated using five sleep categories derived from the RAND Medical Outcome Study Sleep Scale: sleep disturbance, snoring, awaken short of breath/with a headache, sleep adequacy, and daytime somnolence. Four distinct cognitive composite scores were calculated: memory, language, speed of processing, and executive functioning. We used generalized estimating equations analyses with cognitive scores as the outcome, and time, sleep categories and their interactions as the main predictors. Models were initially unadjusted and then adjusted for age, gender, education, ethnicity, depression, and apolipoprotein E-ε4 genotype.
Results
Increased daytime somnolence (including feeling drowsy/sleepy, having trouble staying awake, and taking naps during the day) was linked to slower speed of processing both cross-sectionally (B = −0.143, p = 0.047) and longitudinally (B = −0.003, p = 0.027). After excluding the demented participants at baseline, the results remained significant (B = −0.003, p = 0.021).
Conclusions
Our findings suggest that daytime somnolence may be an early sign of cognitive decline in the older population. Copyright # 2015 John Wiley & Sons, Ltd.
