Association of anxiety and depression with physical and sensory functional difficulties in adults in five population-based surveys in low and middle-income countries

Association of hearing loss with cognitive function and mental health in Africa: A systematic review

OBJECTIVE

To summarize the evidence for the associations between hearing loss and mental health and cognitive function in Africa.

METHODS

This systematic review was prepared following the PRISMA guidelines. Cohort, case‒control and cross-sectional studies were considered for inclusion if they reported the prevalence of any mental health conditions or levels of cognitive functioning among persons with hearing loss/deafness in comparison to those without hearing loss. No age restriction was applied. Articles not published in English or not from the African subcontinent were excluded. The initial search yielded a total of 2,822 articles from electronic databases. After title, abstract and full-text screening, seven articles were found to be eligible, with a total of 2,761 participants across Africa.

RESULTS

Five studies reported that hearing difficulties were significantly associated with an increased prevalence of poor mental health. Two studies reported on cognition, one on higher odds (2.22; 95%CI) of developing cognitive decline among persons with hearing difficulties than among those with normal hearing. The majority of studies were conducted among special populations (i.e., retirement homes and special schools), with most participants being female.

CONCLUSION

This study revealed an increased risk of mental health disorders and/or cognitive decline for people with hearing impairment in African populations. However, the number of relevant studies is small, and more research is needed to provide evidence for public health interventions across the continent.

Disability and labour market participation among smallholder farmers in Western Kenya

BACKGROUND

Despite the importance of labour market participation and the high number of people with disabilities in rural Africa who rely on subsistence agriculture to survive, very few studies have documented labour market outcomes among farmers with and without disabilities in Africa.

OBJECTIVE

We examined how labour market participation differed by disability and other factors among smallholder farmers in Western Kenya.

METHODS

We use cross-sectional data collected between January and April 2022 from sorghum farmers enrolled in a trial evaluating the impact of a programme designed to improve labour market participation among sorghum farmers in rural Western Kenya. Disability and Labour market outcomes were assessed using questions from the Washington Group /ILO Labor Force Survey Disability Module the ILO Labour Force Survey module respectively. Univariate and multiple regression analyses were conducted to identify socio-demographic characteristics and other related factors associated with labour market participation.

RESULTS

Among 4459 participants, disability was reported by 20.3% of women and 12.3% of men. Labour market participation was reported by 77.1% and 81.3% of women and men, respectively. Adjusting for demographic confounders, having a disability was associated with a lower likelihood of labour market participation (odds ratio 0.59, 95% confidence interval, 0.42-0.83, P = 0.001). These findings were similar in a modified model that looked at functional difficulties separately from anxiety and depression. Women, older participants, and those who were dependent on others were also more likely not to report participation in the labour market.

CONCLUSIONS

Increased recognition and understanding of functional limitations among smallholder farmers is vital for the success of economic empowerment programmes aimed at increasing labour market participation among the most vulnerable populations.

Prevalence of Child Functional Difficulties and Its Associated Factors in Bangladesh: An Application of Count Regression Model

Children that are mentally and physically healthy have a higher quality of life and are better able to function in their daily lives. Therefore, this study is aimed at investigating associated factors causing functional difficulties in male and female children ages 5-17 years. This study used data from a nationally representative cross-sectional household survey named the Multiple Indicator Cluster Survey (MICS) Bangladesh 2019. A total of 58,746 children aged 5-17 were selected for the study, where 30,300 children were male, and 28,446 were female. To deal with overdispersed count data, the study used a negative binomial regression model to find the associated factors. The results show that 39.3% of the male children and 40.9% of the female children were from the age group of 10-14. Educated children had a lower risk of dysfunction. Among male children, women with a total number of children ever born of 4 or more were 1.21 times (incidence rate ratios (IRR) = 1.21) more likely to have a dysfunctional child. Children of dysfunctional mothers are more likely to be dysfunctional themselves. The incidence rate ratio for children functional difficulty among Muslim girls was 36 percent higher than non-Muslim girls in Bangladesh. When compared to the Barisal Division, female children in the Mymensingh Division had a 16% higher risk of functional problems. Based on the findings, the Bangladesh government and other development partners should initiate policies and programs to minimize the impact of functional dysfunction in children.

Anxiety and depression in Guatemala: Sociodemographic characteristics and service access

Epidemiological data on depression and anxiety in Guatemala is lacking. Using 2016 National Disability Survey data, we explored the sociodemographics of people with anxiety and/or depression and its heightened burden on access to key services. The survey (n = 13,073) used the Washington Group Extended Set to estimate disability prevalence, including anxiety and/or depression. A nested case-control study was included to explore the impact of disability on key life areas. Cases (indicating ‘A lot of difficulty’ or ‘Cannot do’ in one or more functional domain) and age-/sex-matched controls were administered a structured questionnaire. Multivariable logistic regression and heightened-burden analysis were conducted. Higher odds of anxiety and/or depression were found in participants who were 50+ (aOR 2.3, 1.8–3.1), female (aOR 1.8, 1.4–2.2), urban (aOR 1.5, 1.2–1.9), divorced/separated (aOR 2.0, 1.3–3.0), and widowed (aOR 1.6, 1.0–2.4), as well as those with impaired communication or cognition (aOR 17.6, 13.0–23.8), self-care (aOR 13.2, 8.5–20.5), walking (aOR 13.3, 9.7–18.3), hearing (aOR 8.5, 5.6–13.1), and vision (aOR 8.5, 6.1–11.8). Lower odds of anxiety and/or depression were found in participants with a university education (aOR 0.2, 0.5–0.9), and those living in the southeast (aOR 0.2, 0.1–0.3) or northeast (aOR 0.3, 0.2–0.4). Compared to people with impairments that were not depression and/or anxiety, people with depression and/or anxiety were less likely to receive a retirement pension (aOR 0.4, 0.2–0.8), and more likely to receive medication for depression/anxiety (aOR 4.1, 1.9–9.1), report a serious health problem (aOR 1.8, 1.3–2.5), and seek advice/treatment with a government health worker/health post (aOR 6.3, 1.0–39.2).

The Association between Vision Impairment and Depression: A Systematic Review of Population-Based Studies

We conducted a systematic review and meta-analysis to investigate whether depression is associated with vision impairment (VI) in population-based studies in adults. MEDLINE and EMBASE were searched, from inception to June 2020. Studies were included if they provided two-by-two data for calculating the OR of association between VI and depression, or crude and/or an adjusted odds ratio (OR) with a corresponding 95% confidence interval (CI) were reported. The proportion of VI and depression was also extracted. ORs were pooled using random-effect models, proportions were pooled using random intercepts logistic regression models. Overall, 29 articles (31 studies) were included: of those, 18 studies used survey data (622,312 participants), 10 used clinical examination data (69,178 participants), and 3 used administrative databases (48,162,290 participants). The proportion of depression (95%CI) was 0.17 (0.13-0.22) overall and 0.27 (0.21-0.33) in VI subjects. The proportion of VI was 0.10 (0.07-0.16) overall and 0.20 (0.13-0.29) in depressed subjects. The association between VI and depression was direct: crude ORs were 1.89 (1.51-2.37) for survey data, 2.17 (1.76-2.67) for clinical examination data, and 3.34 (1.01-11.11) for administrative databases; adjusted ORs were 1.75 (1.34-2.30), 1.59 (1.22-1.96), and 2.47 (0.97-6.33), respectively. In conclusion, VI and depression are prevalent morbidities and should be actively sought when either is identified, especially in older adults.

Gender, Mental Health, and Entry Into Care with Advanced HIV Among People Living with HIV in Cameroon Under a National 'Treat All' Policy

Delays in diagnosis and linkage to HIV care persist among people living with HIV (PLWH), even after expanded access to ART worldwide. Mental health may influence timely linkage to HIV care. Greater understanding of the relationship among gender, mental health, and delayed linkage to HIV care can inform strategies to improve the health of PLWH. We interviewed 426 PLWH initiating HIV care in Cameroon between June 2019 and March 2020 to estimate the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) and the association between mental health and entry into care with advanced HIV. Separate multivariable log binomial regression models were used to estimate the association between mental health exposure and entry into HIV care with advanced HIV. Stratified analyses were used to assess effect modification by gender. Approximately 20, 15, and 12% of participants reported symptoms of depression, PTSD, and anxiety, respectively. The prevalence of mental health symptoms did not vary significantly by gender. Overall, 53% of participants enrolled in HIV care with advanced HIV: 51% of men and 54% of women. Screening positive for one of the mental health disorders assessed was associated with greater prevalence of enrollment with advanced HIV among men, but not among women. Future research should examine gender-specific pathways between mental health symptoms and entry into care with advanced HIV, particularly for men in Cameroon. The extent to which untreated mental health symptoms drive gender disparities throughout the HIV care continuum should be explored further.

Depression, combined visual and hearing impairment (dual sensory impairment): a hidden multi-morbidity among the elderly in Residential Care in India

To report the prevalence of depression and its association with combined visual (VI) and hearing impairment (HI) in the elderly in residential care in India. Participants aged ≥ 60 years were recruited from 41 homes. Data on personal and sociodemographic information were obtained. Visual acuity was measured using the logMAR chart. Patient Health Questionnaire (PHQ-9) was used to assess depression, and the Hearing Handicap Inventory for the Elderly Screening (HHIE) was administered to assess hearing status. Data of all 867 eligible elderly participants were analysed. The mean age of the participants was 74.2 years (standard deviation: 8.2 years) and included 537 (61.9%) women and 117 (13.5%) participants who had no education. The prevalence of depression was 60.0% (95% CI: 45.2-73.4) in the elderly with combined VI and HI compared to 20.9% (95% CI:14.4-28.8) among those with VI only and 37.8% (95% CI: 26.6-46.5) among those with HI only. On multiple logistic regression analyses, depression was approximately 5 times higher among the participants with DSI after adjusting for other covariates. Six out of ten elderly with combined HI and VI had depression highlighting the need for screening and referral when elderly present with combined vision and hearing loss.

Association Between Visual Impairment and Depression in Patients Attending Eye Clinics: A Meta-analysis

IMPORTANCE

Given that depression is treatable and some ocular diseases that cause visual loss are reversible, early identification and treatment of patients with visual impairment who are most at risk of depression may have an important influence on the well-being of these patients.

OBJECTIVE

To conduct a meta-analysis on the prevalence of depression in patients with visual impairment who regularly visit eye clinics and low vision rehabilitation services.

DATA SOURCES

MEDLINE (inception to June 7, 2020) and Embase (inception to June 7, 2020) were searched.

STUDY SELECTION

Studies that obtained data on the association between acquired visual impairment and depression among individuals aged 18 years or older were identified and included in this review. Exclusion criteria comprised inherited or congenital eye diseases, review studies, unpublished articles, abstracts, theses, dissertations, and book chapters. Four independent reviewers analyzed the results of the search and performed the selection and data extraction to ensure accuracy.

DATA EXTRACTION AND SYNTHESIS

Meta-analyses of prevalence were conducted using random-intercept logistic regression models. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

MAIN OUTCOMES AND MEASURES

Proportion of depression.

RESULTS

A total of 27 studies were included in this review, and all but 2 included patients older than 65 years. Among 6992 total patients (mean [SD] age, 76 [13.9] years; 4195 women [60%]) with visual impairment, in 1687 patients with depression, the median proportion of depression was 0.30 (range, 0.03-0.54). The random-effects pooled estimate was 0.25 (95% CI, 0.19-0.33) with high heterogeneity (95% predictive interval, 0.05-0.70). No patient characteristic, measured at the study level, influenced the prevalence of depression, except for the inclusion of patients with cognitive impairment (0.33; 95% CI, 0.28-0.38 in 14 studies vs 0.18; 95% CI, 0.11-0.30 in 13 studies that excluded this with major comorbidities; P = .008). The prevalence of depression was high both in clinic-based studies (in 6 studies, 0.34; 95% CI, 0.23-0.47) and in rehabilitation services (in 18 studies, 0.25; 95% CI, 0.18-0.33 vs other settings in 3 studies, 0.15; 95% CI, 0.05-0.38; P = .17), and did not vary by visual impairment severity of mild (in 8 studies, 0.24; 95% CI, 0.14-0.38), moderate (in 10 studies, 0.29; 95% CI, 0.21-0.39), and severe (in 5 studies, 0.29; 95% CI, 0.12-0.56; P = .51).

CONCLUSIONS AND RELEVANCE

The results of this meta-analysis suggest that depression in patients with visual impairment is a common problem that should be recognized and addressed by the health care professionals treating these patients.
