Culturally sensitive validation of screening questionnaires for depression in older African-Caribbean people living in south London

Relationship between traits and sleep quality of hospitalized elderly patients and sleep quality of family caregivers

AIM

To understand whether the sleep quality of the caregivers of elderly inpatients is associated with their own characteristics and with the characteristics or sleep quality of the elderly inpatients.

DESIGN

A cross-sectional study design that recruited participants from September to December 2020 was adopted, in which 106 pairs of elderly inpatients and caregivers were recruited.

METHODS

Data collected from the elderly inpatients included demographic characteristics as well as the numerical rating scale (NRS) score, Charlson Comorbidity Index (CCI), Geriatric Depression Scale Short Form (GDS-SF) score, and Pittsburgh Sleep Quality Index (PSQI). Caregiver data included demographic characteristics and PSQI.

RESULTS

In the regression analysis of caregiver characteristics and caregiver sleep quality, only caregiver age and the relationship between caregiver and inpatient (other vs. spouse) were correlated with caregiver sleep quality. In the regression analysis of elderly inpatient characteristics, caregiver characteristics, and caregiver sleep quality, only the PSQI of elderly inpatients and the relationship between caregiver and inpatient (other vs. spouse) were correlated with caregiver sleep quality.

PATIENT OR PUBLIC CONTRIBUTION

Poor caregiver sleep quality was more likely to manifest when the elderly inpatients had poor sleep quality, when the caregivers themselves were older, and when the caregiver was the inpatient's spouse.

Perinatal Mental Health Disorders: A Review of Lessons Learned from Obstetric Care Settings

Perinatal mental health has garnered significant attention within obstetrics over the last couple of decades as the long- and short-term morbidities of untreated perinatal mental health disorders on both the mother and fetus/neonate have become increasingly apparent. There have been major strides in increasing screening for perinatal mental health disorders, clinician comfort with prescribing common psychiatric medications, and integrating mental health professionals into prenatal care via health services approaches such as the collaborative care model. Despite these advances, however, gaps still remain in the tools used for screening and diagnosis, obstetric clinician training in diagnosis and management of perinatal mood and anxiety disorders, as well as patient access to mental health care during pregnancy and especially postpartum. Herein we review the state of perinatal mental health from the perspective of the obstetric provider and identify areas of ongoing innovation.

Impacts of the Goldmining and Chronic Methylmercury Exposure on the Good-Living and Mental Health of Munduruku Native Communities in the Amazon Basin

This paper is an exploratory study that examines the illegal goldmining impacts on Munduruku communities' "Good-Living" (Xipan Jewewekukap) and explores the possible relationship between chronic methylmercury (MeHg) exposure and the worsening mental health conditions in three villages in the Middle-Tapajós River, Brazilian Amazon. The region has been experiencing a long-lasting threat of goldminers' invasions. A total of 109 people were interviewed and evaluated. Total mercury (THg) exposure levels were evaluated through hair samples analysis, from which MeHg exposure levels were calculated. The Geriatric Depression Scale-Short Form (GDS-SF) was used as a screening tool in order to assess mental health indicators. Brief non-structured interviews were carried out to investigate how goldmining is impacting the communities Good-Living. A Poisson regression model was used to estimate the possible association between mental health indicators (assessed through the GDS-SF) and the following independent variables: (i) mercury exposure level (<10.0 μg/g vs. ≥10.0 μg/g), (ii) self-reported nervousness, (iii) self-reported irritability, (iv) age group, and (v) monthly income. The analysis revealed high levels of mercury in hair samples (median: 7.4 µg/g, range 2.0-22.8; 70% and 28% of the participants had THg levels ≥6.0 and ≥10.0 µg/g, respectively) and pointed to a tendency in which higher levels of methylmercury exposure (Hg ≥ 10.0 µg/g) could be linked to worse mental health indicators. Although the GDS-SF has presented limitations due to the Munduruku sociocultural context, our findings suggest a tendency of worse mental health indicators in participants presenting high levels of MeHg exposure. Despite this limitation, the qualitative approach indicates an evident association between the impacts of goldmining and the Munduruku people's decreasing autonomy to maintain a Good-Living on their own terms, pointing to the importance of carrying out new investigations, especially considering longitudinal studies with qualitative methodologies and ethnographic approaches.

Taiwanese Depression Questionnaire and AD8 Questionnaire for Screening Late-Life Depression in Communities

BACKGROUND

Major depressive disorder (MDD) presents with emotional and somatic symptoms and sometimes subjective cognitive complaints (SCCs). This study developed a collaborative method to integrate SCC assessment for evaluating late-life MDD.

METHODS

Residents aged >50 years in the Community Medicine Research Center of Keelung Chang Gung Memorial Hospital in Taiwan during 2017-2018 were prospectively recruited in this study. The participants were asked to report their depressive tendency and SCCs using the Taiwanese Depression Questionnaire (TDQ) and the AD8, respectively, and were administered psychiatric evaluation through the Mini-International Neuropsychiatric Interview (MINI). The participants were divided into elderly (age≥65 years) and older adult (age 50-65) groups. The MDD predictive powers were assessed using logistic regression and receiver operating characteristic (ROC) curve analyses.

RESULTS

Of the 118 enrolled participants (mean age: 64.81±4.99, female-to-male ratio: 1.62), 9, 21, and 88 were categorized as those with current MDD, past MDD, and non-MDD on the basis of the MINI results, respectively. After adjustments for age, sex, and sleep quality, the TDQ score (odds ratio: 1.152, p=0.003) and AD8 score (odds ratio: 1.710, p=0.020) were used individually to predict current MDD. Overall, the TDQ individually predicted current MDD well with area under the ROC curve (AUC) of 0.835 (p=0.001). However, in the elderly group (N=63), the TDQ score did not identify current MDD well (AUC: 0.780, p=0.063). After co-considering SCCs, the linear combination of the sum of the TDQ score and four folds of the AD8 score could effectively distinguished elderly people with current MDD from those without it (AUC: 0.875, p=0.013)-with the cutoff of the aforementioned combined score being ≥32.

CONCLUSION

The self-reported response to the TDQ is a feasible approach of identifying MDD in community-dwelling people. Combining TDQ and AD8 scores further improved depression detection in elderly people.

Mental health of the ageing immigrant population

About 6% of older people in the UK are immigrants. Concentrated in deprived inner-city areas, their numbers are rising rapidly, with the ageing of those arriving after the Second World War. Cultural, language and educational differences cause problems in studying this group's mental health. Idioms of distress may affect presentation, help-seeking behaviour and acceptability of treatment. Ethnic elders may be considered vulnerable to depression because of socio-economic deprivation, immigrant status and old age but studies are contradictory and may use inappropriate screening instruments. Relatively few consider immigrant status and dementia. Uncontrolled hypertension could relate to higher dementia rates in Black immigrants which are not reflected in the country of origin. No genetic risk has been found. There is potential for prevention in this population.

Negative Emotional Verbal Memory Biases in Mild Cognitive Impairment and Late-Onset Depression

OBJECTIVE

Early and preferential targeting of limbic structures by Alzheimer disease (AD)-related pathology suggests emotion dysregulation may serve as a marker of AD risk. We studied emotional verbal memory in two groups at risk for AD, amnestic mild cognitive impairment (aMCI) and late-onset depression (LOD), to test the hypothesis that aMCI and LOD would be characterized by a negative bias in emotional memory, whereas cognitively normal (CN) adults would show the "positivity effect" associated with healthy aging.

METHODS

Participants completed a novel test of emotional verbal memory, the Emotional Verbal Learning Test (EVeLT), consisting of a 15-item list of words with positive, negative, or neutral valence. Recall as a function of group and valence was analyzed using mixed analysis of variance. Spearman's rho was used to examine associations between EVeLT, mood, and executive function. MCI and CN participants had no current or past history of mood or anxiety disorders. aMCI participants met neuropsychological criteria for single-domain aMCI (sd-aMCI). LOD developed their first episode of depression at ≥60 years of age.

RESULTS

CN adults recalled more positive words, whereas sd-aMCI and LOD adults recalled more negative, relative to neutral, words on the EVeLT. Positive emotional memory and negative attitudes regarding self were inversely correlated in CN adults.

CONCLUSION

sd-aMCI and LOD groups show negative emotional memory biases, consistent with our hypothesis that emotion dysregulation is a signature of AD risk.

The diagnostic accuracy of brief versions of the Geriatric Depression Scale: a systematic review and meta-analysis

BACKGROUND

Depression in older adults is often under recognised despite it being the most common mental health illness in this age group. An increasing older adult population highlights the need for improved diagnostic rates. Brief versions (15 items or less) of the Geriatric Depression Scale (GDS), which are suitable for busy clinical practice, could improve detection rates.

OBJECTIVE

Our aim is to establish the diagnostic accuracy of brief versions of the GDS.

METHODS

Twelve electronic databases of published and unpublished literature were searched. Study selection was in accordance with predefined inclusion and exclusion criteria. A recognised gold-standard diagnostic instrument was used as a comparator against data pertaining to the use of a brief version of the GDS in an older adult population. The QUADAS-II was utilised for quality assessment. Narrative analysis and, where possible, meta-analysis were performed.

RESULTS

Thirty-two studies were identified that provided diagnostic data regarding seven brief versions of the GDS (1, 4, 5, 7 8, 10 and 15-item versions). Pooled sensitivity was 0.89 (95% confidence interval (CI) 0.80-0.94), and specificity was 0.77 (95% CI 0.65-0.86) for the GDS-15 at the recommended cut-off score of 5. Meta-analysis of other brief versions was not possible because of an insufficient number of studies with standardised items.

CONCLUSIONS

Results suggest the possibility of selective reporting of cut-off scores, and therefore, findings should be approached cautiously. Studies should report all cut-off scores, and all brief GDS versions should be compiled of standardised items. Copyright © 2016 John Wiley & Sons, Ltd.

Depressive symptoms are doubled in older British South Asian and Black Caribbean people compared with Europeans: associations with excess co-morbidity and socioeconomic disadvantage

BACKGROUND

Despite elevated risk profiles for depression among South Asian and Black Caribbean people in the UK, prevalences of late-life depressive symptoms across the UK's three major ethnic groups have not been well characterized.

METHOD

Data were collected at baseline and 20-year follow-up from 632 European, 476 South Asian and 181 Black Caribbean men and women (aged 58-88 years), of a community-based cohort study from north-west London. The 10-item Geriatric Depression Scale was interviewer-administered during a clinic visit (depressive symptoms defined as a score of ⩾4 out of 10), with clinical data (adiposity, diabetes, cardiovascular disease, cognitive function) also collected. Sociodemographic, psychosocial, behavioural, disability, and medical history information was obtained by questionnaire.

RESULTS

Prevalence of depressive symptoms varied by ethnic group, affecting 9.7% of White European, 15.5% of South Asian, and 17.7% of Black Caribbean participants. Compared with White Europeans, South Asian and Black Caribbean participants were significantly more likely to have depressive symptoms (odds ratio 1.79, 95% confidence interval 1.24-2.58 and 1.80, 1.11-2.92, respectively). Adjustment for co-morbidities had most effect on the excess South Asian odds, and adjustment for socioeconomic position had most effect on the elevated Black Caribbean odds.

CONCLUSIONS

Higher prevalence of depressive symptoms observed among South Asian people were attenuated after adjustment for physical health, whereas the Black Caribbean increased prevalence was most explained by socioeconomic disadvantage. It is important to understand the reasons for these ethnic differences to identify opportunities for interventions to address inequalities.

Do HIV-positive women receive depression treatment that meets best practice guidelines?

This study addressed whether psychopharmacologic and psychotherapeutic treatment of depressed HIV+ women met standards defined in the best practice literature, and tested hypothesized predictors of standard-concordant care. 1,352 HIV-positive women in the multi-center Women's Interagency HIV Study were queried about depressive symptoms and mental health service utilization using standards published by the American Psychiatric Association and the Agency for Healthcare Research and Quality to define adequate depression treatment. We identified those who: (1) reported clinically significant depressive symptoms (CSDS) using Centers for Epidemiological Studies-Depression Scale scores of ≥16; or (2) had lifetime diagnoses of major depressive disorder (MDD) assessed by World Mental Health Composite International Diagnostic Interviews plus concurrent elevated depressive symptoms in the past 12 months. Adequate treatment prevalence was 46.2 % (n = 84) for MDD and 37.9 % (n = 211) for CSDS. Multivariable logistic regression analysis found that adequate treatment was more likely among women who saw the same primary care provider consistently, who had poorer self-rated role functioning, who paid out-of-pocket for healthcare, and who were not African American or Hispanic/Latina. This suggests that adequate depression treatment may be increased by promoting healthcare provider continuity, outreaching individuals with lower levels of reported role impairment, and addressing the specific needs and concerns of African American and Hispanic/Latina women.

Identifying depression in South asian patients with end-stage renal disease: considerations for practice

Depression is a prevalent burden for patients with end-stage renal disease (ESRD) and one that is under-recognized and consequently under-treated. Although several studies have explored the association between depression symptoms, treatment adherence and outcomes in Euro-American patient groups, quantitative and qualitative exploration of these issues in patients from different cultural and ethnic backgrounds has been lacking. This review discusses the methodological issues associated with measuring depression in patients of South Asian origin who have a 3- to 5-fold greater risk of developing ESRD. There is a need to advance research into the development of accurate screening practices for this patient group, with an emphasis on studies utilizing rigorous approaches to evaluating the use of both emic (culture-specific) and etic (universal or culture-general) screening instruments.

Diagnostic validity and added value of the Geriatric Depression Scale for depression in primary care: a meta-analysis of GDS30 and GDS15

BACKGROUND

The Geriatric Depression Scale (GDS) has been evaluated in hospital settings but its validity and added value in primary care is uncertain. We therefore conducted a meta-analysis analysing the diagnostic accuracy, clinical utility and added value of the GDS in primary care.

METHODS

A comprehensive search identified 69 studies that measured the diagnostic validity of the GDS against a semi-structured psychiatric interview and of these 17 analyses (in 14 publications) took place in primary care. Seven studies examined the GDS(30) and 10 studies examined the GDS(15). Heterogeneity was moderate to high, therefore random effects meta-analysis was used.

RESULTS

Diagnostic accuracy of the GDS(30) after meta-analytic weighting was given by a sensitivity of 77.4% (95% CI=66.3% to 86.8%) and a specificity=65.4% (95% CI=44.2% to 83.8%). For the GDS(15) the sensitivity was 81.3% (95% CI=77.2% to 85.2%) and specificity=78.4% (95% CI=71.2% to 84.8%). The fraction correctly identified (also known as efficiency) by the GDS(15) was significantly higher than the GDS(30) (77.6% vs 71.2%, Chi(2)=24.8 P<0.0001). The clinical utility of both the GDS(30) and GDS(15) was "poor" for case-finding (UI+ 0.29, UI+ 0.32 respectively). However the GDS(15) was rated as "good" for screening (UI- 0.75) whereas the GDS(30) was "adequate" (UI- 0.60). Concerning added value, when identification using the GDS was compared with general practitioners' ability to diagnose late-life depressions unassisted by tools, at a prevalence of 15% the GDS(30) had no added benefit whereas the GDS(15) helped identify an additional 4 cases per 100 primary care attendees and also helped rule-out an additional 4 non-cases per 100 attendees. Thus we estimate the potential gain of the GDS(15) in primary care to be 8% over unassisted clinical detection but at a cost of 3-4 minutes of extra time per appointment.

CONCLUSION

The GDS yields potential added value in primary care. We recommend the GDS(15) but not the GDS(30) in the diagnosis of late-life depression in primary care.

Psychiatry of old age and ethnic minority older people in the United Kingdom

This review examines the demographic changes, the epidemiology of mental disorders and suicides, the potential risk and protective factors, access to secondary care old age psychiatry services (OAPSs) and the policy context pertaining to older people from ethnic minority groups in the United Kingdom. The number of older people from ethnic minority groups is increasing. The prevalence of mental disorders in older people from ethnic minority groups is either similar to or higher than that in the indigenous population. Therefore, the number of older people from ethnic minority groups with psychiatric morbidity is also increasing. Ethnic minority older people also have inequity of access to secondary care OAPSs. There is an urgent need to develop and implement practical strategies to improve access by older people from ethnic minority groups to OAPSs.

Criterion-based validity and reliability of the Geriatric Depression Screening Scale (GDS-15) in a large validation sample of community-living Asian older adults

BACKGROUND

Few studies have evaluated the validation of 15-item Geriatric Depression Scale (GDS-15) in a heterogeneous population with different age, ethnicity and comorbidities of elderly users of social services in the community.

AIMS

To assess the criterion validity and reliability of the GDS-15 and its equivalence across different gender, age groups, ethnicity and different comorbidities in community living elderly and nursing homes residents.

METHOD

A validation sample of non-demented 4253 elderly (age > or = 60 years), who regularly use community based care corner, senior activity center, day care center, sheltered homes and nursing homes were interviewed using the GDS-15. Structured clinical interview (SCID) was used to make DSM-IV diagnosis of major depressive disorder (MDD).

RESULTS

The overall sensitivity and specificity were 0.97 and 0.95, respectively (area under curve, AUC was 0.98). The overall Cronbach's alpha was 0.80, and intraclass coefficient of test--retest reliability over 2 weeks was 0.83 and inter-rater reliability was 0.94 (intra-class) and 0.99 (Cohen's kappa). Although some items in the GDS-15 appeared to be biased by gender, age and ethnicity, there were no clinically significant differences in test performance among different age, gender, ethnicity and comorbidities at cutoff of 4/5.

CONCLUSIONS

The GDS-15 was a reliable and valid screening for MDD across different age, gender, ethnicity and chronic illness status in the community and social service setting.

Prevalence and predictors of depression among an elderly population of Pakistan

OBJECTIVE

To assess the magnitude and risk factors of the problem of depression in an elderly population of Pakistan.

METHOD

A cross-sectional study was conducted using a sample of 402 people aged 65 and above visiting the Community Health Center of the Aga Khan University, Karachi. Questionnaire based interviews were conducted for data collection and the 15-Item Geriatric Depression Scale was used to screen for depression. Univariate and multivariate logistic regression analyses were performed to identify factors associated with depression.

RESULTS

Of the 402 participants; 69.7% (95% CI=+/-4.5%) were men, 76.4% (95% CI=+/-4.2%) were currently married, 36.8% (95% CI=+/-5%) had received 11 or more years of education and 24.4% (95% CI=+/-4.2%) were employed. The mean age was 70.57 years (SD=+/-5.414 years). The prevalence of depression was found to be 22.9% (95% CI=+/-4.1%) and multiple logistic regression analysis indicated that higher number of daily medications (p-value=0.03), total number of health problems (p-value=0.002), financial problems (p-value<0.001), urinary incontinence (p-value=0.08) and inadequately fulfilled spiritual needs (p-value = 0.067) were significantly associated with depressive symptoms.

CONCLUSION

We have identified several risk factors for depression in the elderly which need to be taken into account by practicing family physicians and health care workers.

An efficient screening tool for preoperative depression: the Geriatric Depression Scale-Short Form

BACKGROUND

Depression is highly prevalent in patients before surgery, and it has been widely shown to have a serious impact on their postoperative outcomes. It would therefore be desirable for physicians to obtain a quick, simple screen to evaluate depression to consider treatment of symptomatology and potentially optimize postoperative outcomes.

METHODS

In this study, we investigated the prevalence of depression in a presurgical inpatient sample undergoing major, noncardiac surgery. In addition, we sought to establish the Geriatric Depression Scale-Short Form (GDS-SF) as a valid screening tool for depression by examining its relationship to the Beck Depression inventory (BDI) by age and gender.

RESULTS

In our sample of 1043 presurgical candidates, prevalence of depression as established by the BDI was significantly higher than rates consistently found in healthy community samples. Depression was more common in women than in men (P = 0.02), and depression rates were lower in elders relative to middle-aged and younger groups (P = 0.003 and 0.003, respectively). In addition, we found that there was a high correlation between the BDI and the GDS-SF within each of the age groups.

CONCLUSIONS

These data further support the need for depression screens in presurgical populations and establish the validity of the GDS-SF as a valid quick assessment alternative available to physicians.

Depression in the elderly: does family system play a role? A cross-sectional study

BACKGROUND

The most common geriatric psychiatric disorder is depression. The role of family systems in depression among the elderly has not been studied extensively. It has been suggested that urbanization promotes nucleation of family systems and a decrease in care and support for the elderly. We conducted this study in Karachi, a large urban city of Pakistan, to determine the relationship between the type of family system and depression. We also determined the prevalence of depression in the elderly, as well as correlation of depression with other important socio-demographic variables.

METHODS

A cross-sectional study was carried out in the premises of a tertiary care hospital in Karachi, Pakistan. Questionnaire based interviews were conducted among the elderly people visiting the hospital. Depression was assessed using the 15-item Geriatric Depression Scale.

RESULTS

Four hundred subjects aged 65 and above were interviewed. The age of majority of the subjects ranged from 65 to 74 years. Seventy eight percent of the subjects were male. The prevalence of depression was found to be 19.8%. Multiple logistic regression analysis revealed that the following were significant (p < 0.05) independent predictors of depression: nuclear family system, female sex, being single or divorced/widowed, unemployment and having a low level of education. The elderly living in a nuclear family system were 4.3 times more likely to suffer from depression than those living in a joint family system (AOR = 4.3 [95% CI = 2.4-7.6]).

CONCLUSION

The present study found that residing in a nuclear family system is a strong independent predictor of depression in the elderly. The prevalence of depression in the elderly population in our study was moderately high and a cause of concern. The transition in family systems towards nucleation may have a major deleterious effect on the physical and mental health of the elderly.

Illicit drug use, depression and their association with highly active antiretroviral therapy in HIV-positive women

BACKGROUND

We examined the interaction of illicit drug use and depressive symptoms, and how they affect the subsequent likelihood of highly active antiretroviral therapy (HAART) use among women with HIV/AIDS.

METHODS

Subjects included 1710 HIV-positive women recruited from six sites in the U.S. including Brooklyn, Bronx, Chicago, Los Angeles, San Francisco/Bay Area, and Washington, DC. Cases of probable depression were identified using depressive symptom scores on the Center for Epidemiologic Studies Depression Scale. Crack, cocaine, heroin, and amphetamine use were self-reported at 6-month time intervals. We conducted multivariate random logistic regression analysis of data collected during 16 waves of semiannual interviews conducted from April 1996 through March 2004.

RESULTS

We found an interaction effect between illicit drug use and depression that acted to suppress subsequent HAART use, controlling for virologic and immunologic indicators, socio-demographic variables, time, and study site.

CONCLUSIONS

This is the first study to document the interactive effects of drug use and depressive symptoms on reduced likelihood of HAART use in a national cohort of women. Since evidence-based behavioral health and antiretroviral therapies for each of these three conditions are now available, comprehensive HIV treatment is an achievable public health goal.

The criterion validity of the Geriatric Depression Scale: a systematic review

OBJECTIVE

The objective was to provide a systematic review of the screening accuracy of both versions of the Geriatric Depressions Scale (GDS-30, GDS-15).

METHOD

An electronic search was performed by using Medline, Embase, Cinahl, Psyndex and the Cochrane library. The selection and examination of papers were performed by two reviewers independently.

RESULTS

Among the 42 papers included, important methodological aspects such as sampling methods or blinding of research workers often were not reported. For both GDS versions, similar validity indices were found (GDS-30: sensitivity 0.753, specificity 0.770; GDS-15: sensitivity 0.805, specificity 0.750). Using comparative studies based on the identical samples, both GDS versions showed significantly better validity indices than the 'Yale-1-question' screen, but were similar to the 'Center for Epidemiological Studies Depression scale' (CES-D).

CONCLUSION

The GDS does not show a better criterion validity than the CES-D, but methodological limitations of primary studies hamper the generalizability of pooled analyses.

Effects of treated and untreated depressive symptoms on highly active antiretroviral therapy use in a US multi-site cohort of HIV-positive women

This study examines the effects of treated and untreated depressive symptoms on the likelihood of utilization of highly active antiretroviral therapy (HAART) among a multi-site cohort of HIV-infected women who screened positive for probable depression. Data were collected biannually from 1996 through 2001 in a prospective cohort study. Random-effects regression analysis was used to estimate the longitudinal effects of mental health treatment on the probability of HAART utilization, controlling for clinical indicators (CD4 count, viral load), demographic features (race/ethnicity, income), and behavioural factors (recent crack, cocaine, or heroin use). Use of antidepressants plus mental health therapy, or use of mental health therapy alone significantly increased the probability of HAART utilization, compared to receiving no depression treatment. Use of antidepressants alone did not differ significantly from receiving no depression treatment. African American women and those who used crack, cocaine, or heroin also were less likely to use HAART. These findings suggest that efforts to enhance depressed women's access to psychopharmacologic treatment and therapy may increase their use of the most effective HIV therapies.

Prevalence and correlates of depression in late life: a population based study from a rural Greek town

BACKGROUND

Depression in late life is common and has serious consequences on function, medical co-morbidity, quality of life, and use of medical services.

OBJECTIVE

To estimate the age- and gender-specific prevalence of depression among people over 60 years of age, and to examine correlates of depression, in particular the relationship between depression and cognitive impairment.

METHOD

From a total of 965 inhabitants, aged over 60 years, in Velestino, a rural town in central Greece, 608 were accessible and constituted the target population. During a five-month period in 2000, a trained health visitor interviewed all study participants. The interview covered socio-demographic characteristics, medical history, and administration of the 15-question Geriatric Depression Scale (GDS-15) and the Mini Mental Scale Examination instrument (MMSE).

RESULTS

The prevalence of mild or more severe depression (GDS> or =7) was 27%, while the prevalence of moderate to severe depression (GDS> or =11) was 12%. Increasing age, female gender, lower education, and being currently unmarried were associated with higher risk of depression in univariate regression models, but these associations disappeared after controlling for cognitive function, except for the association with marital status. Cognitive impairment was strongly associated with increased risk for depression. The co-morbid presence of digestive, neurological and heart conditions was also associated with increased risk for depression, while cancer was not.

CONCLUSION

In a rural Greek area, the prevalence of depression in late life is high. Depression was more common among unmarried individuals, those with significant cognitive impairment, and in association with specific medical conditions.

Depression in chronic haemodialysed patients

From April 2000 to April 2001, a total of 108 chronic stable haemodialysed patients (34 males aged 57.76 +/- 12.68 years under haemodialysis treatment for 31.41 +/- 24.71 months and 74 females aged 54.99 +/- 12.87 years under haemodialysis for 41.47 +/- 33.47 months) were studied for signs of clinical depression. Depression was measured by using 'The Taiwanese Depression Questionnaire (TDQ)'. After analysing various possible factors, we chose to study three dimensions: affective change, somatic complaint and cognitive disturbance. Thirty-six (33.4%) of the patients were found to have TDQ scores above 19; our cut-off value. Diabetic patients were also found to have higher depression scores and affective change scores than those without diabetes. The elderly suffered more from somatic complaints, and patients without jobs also tended to have higher depression scores. We compared the nutrition indexes and uraemic toxin removal indexes of those with higher depression scores (score > or =19) with those with normal scores (score <19), and we found no differences between the two groups. We found that an underlying disease and job status were the major differences found in the two groups. Therefore, our findings suggest that the depression found in our chronic haemodialysed patients was not a result of the physical conditions, but a result of psychosocial problems indicating a need for psychosocial support for these patients.

Mental health of migrant elders--the Islington study

BACKGROUND

In the UK, 6% of those aged 65 years and over were born abroad, most of whom now live in inner-city areas. It has been suggested that ethnic elders are particularly vulnerable to mental illness.

AIMS

To compare the prevalence of dementia and depression in older migrants with those born in the UK.

METHOD

A cross-sectional community study of 1085 people aged 65 years or older in an inner-London borough.

RESULTS

Compared with those born in the UK, the prevalence of dementia was raised in African-Caribbeans (17.3%, relative risk=1.72, Cl=1.06-2.81) and lower for the Irish-born (3.6%, relative risk=0.36, Cl=0.17-0.87). All those of African-Caribbean country of birth were significantly younger (P=0.000) but no more likely to be taking antihypertensive drugs. They were no more likely to report having cardiovascular problems but had increased rates of diabetes (P<0.0000). The overall prevalence of depression was 18.3% (95% Cl=16.1-20.7). The highest prevalence rate was found among those born in Greece and Turkey (27.2%, Cl=17.9-39.6). Migration per se does not appear to be a risk for depression and dementia in this population.

CONCLUSIONS

The excess of dementia may be of vascular aetiology. There is the potential for primary or secondary prevention.

Stroke, vascular risk factors and depression: Cross-sectional study in a UK Caribbean-born population

BACKGROUND

Stroke, hypertension and diabetes are common in older Caribbean-born populations in the UK who may be at risk of depression secondary to vascular disease.

AIMS

We examined the association between stroke, vascular risk factors and depression in a community-based Caribbean-born population aged 55-75 years.

METHOD

Vascular risk factors were identified by interview, examination and blood tests. Depression was categorised using the Geriatric Depression Scale. Disablement was assessed as a potential mediating factor.

RESULTS

Physical illness and disablement were strongly associated with depression, independent of disablement. Previous stroke was associated with depression, independent of disablement. No vascular risk factors were associated with depression.

CONCLUSIONS

The risk of depression associated with stroke was not explained by disablement. However, the hypothesis that vascular risk factors are important in the genesis of depression was not supported.
