Prevalence and associated factors of depression among older adults in rural Tanzania

Knowledge and attitudes towards Alzheimer's disease and related dementias among Nigerian medical and nursing students: a comparative study

INTRODUCTION

Dementia is a growing public health challenge globally, with low- and middle-income countries, including Nigeria, disproportionately affected. Healthcare professionals play a critical role in dementia care. This study compared the knowledge and attitudes of medical and nursing students at a Nigerian university toward Alzheimer's Disease and Related Dementias (ADRD).

METHODS

This cross-sectional study was conducted at the College of Medicine University of Ibadan, Nigeria. A total of 143 penultimate and final-year medical and nursing students were selected by stratified random sampling. Data were collected using the Alzheimer's Disease Knowledge Scale (ADKS) and Dementia Care Attitude Scale (DCAS). Multivariate analysis of variance (MANOVA) was used to compare mean scores between these students. Multivariate regression models were developed to identify factors significantly associated with ADKS and DCAS scores. Statistical significance was determined using a two-tailed p-value of < 0.05.

RESULTS

The mean age of participants was 22.61 years (SD ± 2.56). Medical students demonstrated significantly higher knowledge scores (19.82, SD ± 3.17) compared to nursing students (17.39, SD ± 2.65; p < 0.001) on a scale of 0 to 30. Attitudes measured using the Dementia Care Attitude Scale (DCAS) showed no significant difference between groups, with medical students scoring slightly higher. Multiple regression analysis identified department as a significant predictor of knowledge (p < 0.001) and attitudes (p = 0.010).

CONCLUSION

The study highlights gaps in dementia education among medical and nursing students in Ibadan. Targeted educational interventions, including enhanced curriculum content and experiential learning opportunities, are urgently needed to improve dementia care preparedness in the healthcare workforce.

The burden of generational harm due to alcohol use in Tanzania: A mixed method study of pregnant women

BACKGROUND

Rates of prenatal alcohol use in Sub-Saharan Africa (SSA) are increasing despite regulatory bodies urging pregnant women to abstain from alcohol. Tanzania has minimal policies, interventions, and educational programs addressing prenatal alcohol exposure. Consequently, a considerable number of mothers and their fetuses are exposed to alcohol, leading to serious health consequences like fetal alcohol spectrum disorder (FASD). Our study aims to understand the alcohol use practices of pregnant women, the knowledge and attitudes related to prenatal alcohol exposure among different genders and generations, and how these may be influenced by community perceptions and cultural beliefs among patients at Kilimanjaro Christian Medical Center (KCMC).

METHODS

A total of 676 individuals seeking care at the KCMC Emergency Department (ED) or Reproductive Health Center (RHC) met our inclusion criteria, were approached for participation using a systematic random sampling method, and were enrolled. Of those, 541 women and 114 men completed the survey. The quantitative analysis focused exclusively on survey data from 533 women who reported their pregnancy status and age. Descriptive frequencies were used to compare sociodemographic factors and alcohol use practices across three female groups stratified by pregnancy status and age. Nineteen survey participants-both men and women-were purposively selected for qualitative semi-structured in-depth interviews (IDIs) exploring knowledge, attitudes, and cultural beliefs surrounding alcohol use during pregnancy. A grounded theory approach was used to analyze IDIs in NVivo.

RESULTS

A large percentage of pregnant women reported consuming alcohol at least once per week (42.2%). Older non-pregnant women exhibited the highest rate of alcohol use per week (66.0%). Many older non-pregnant women (28.7%) perceived alcohol use as acceptable during pregnancy. Younger non-pregnant women had the highest prevalence of harmful or hazardous drinking (HHD) at 16.4%. This group also reported the highest weekly alcohol expenses, with 18.1% spending over 10,000 Tanzanian shillings (TZS) per week. Median [IQR] DrInC scores were 0 [0-0] for pregnant women, 0 [0-7] for younger non-pregnant women, and 0 [0-1] for older non-pregnant women. Older non-pregnant women exhibited the highest prevalence of depression (31.4%). Median [IQR] PHQ-9 scores were 4 [3-6.25] for pregnant women, 5 [2-8] for younger non-pregnant women, and 6 [3-10] for older non-pregnant women. Qualitative analyses demonstrated that (1) cultural beliefs are intricately tied to perceived benefits of prenatal alcohol exposure, (2) a history of alcohol use preceding pregnancy largely influences prenatal alcohol use, and (3) community views of PWCA are negative.

CONCLUSIONS

Our findings demonstrate high rates of prenatal alcohol use in Moshi, Tanzania, with pre-pregnancy alcohol use as a significant predictor. Despite generally negative views of pregnant women who consume alcohol (PWCA), some sociocultural beliefs and limited knowledge about the dangers of prenatal alcohol exposure encouraged alcohol use during pregnancy. To improve health outcomes and reduce alcohol-related pregnancy complications for current and future generations, community-wide health messaging and pre-pregnancy interventions may prove beneficial for pregnant women and women of reproductive age who consume alcohol.

Effects of Dance-Based Aerobic Training on Mental Health and Quality of Life in Older Adults with Mild Cognitive Impairment

(1) Background: Mild cognitive impairment in older adults is a condition characterized by a decrease in mental abilities that affects their quality of life. The aim of this study is to evaluate the effects of an aerobic training program based on dance on depression, sleep quality, and quality of life in older adults with mild cognitive impairment. (2) Methods: This study employed a randomized controlled trial design with a total of 92 older adults with cognitive impairment, randomly assigned to an experimental group (n = 47) undergoing dance-based aerobic training and a control group (n = 45) who did not receive any intervention. Depression was assessed using the Yesavage Geriatric Depression Scale, sleep quality through the Pittsburgh Sleep Quality Index (PSQI), and quality of life through the SF-36 questionnaire. (3) Results: Statistically significant improvements were observed in depression (t(46) = 4.783, p = 0.000) and in the PSQI domains: subjective sleep quality (t(46) = 3.333, p = 0.002, and Cohen's d = 0.35), sleep duration (t(46) = 5.511, p = 0.000, and Cohen's d = 0.73) and PSQI total score (t(46) = 2.116, p = 0.040, and Cohen's d = 0.20). Regarding quality of life, improvements were observed in all domains of the questionnaire: the general health (t(46) = -9.374, p = 0.000, and Cohen's d = 0.03), physical function (t(46) = -9.374, p = 0.000, and Cohen's d = 0.03), the physical role (t(46) = -5.954, p = 0.000, and Cohen's d = 1.06), the emotional role (t(46) = -6.200, p = 0.000, and Cohen's d = 0.80), social function (t(46) = -5.585, p = 0.000, and Cohen's d = 0.53), physical pain, (t(46) = -9.224, p = 0.000, and Cohen's d = 1.04), vitality (t(46) = 2.289, p = 0.027, and Cohen's d = 1.27), mental health, (t(46) = -7.985, p = 0.000, and Cohen's d = 1.33), the physical summary component, (t(46) = -13.532, p = 0.000, and Cohen's d = 1.81), and in the mental summary component (t(46) = -10.6 81, p = 0.000, and Cohen's d = 0.06); (4) Conclusions: The results of the present study showed that they suggest that a dance-based aerobic training program improves mental health and quality of life in older people with mild cognitive impairment, providing a non-pharmacological approach to improve general well-being in this population.

pH-Sensitive In Situ Gel of Mirtazapine Invasomes for Rectal Drug Delivery: Protruded Bioavailability and Anti-Depressant Efficacy

The present research emphasizes fabrication alongside the assessment of an innovative nano-vesicular membranous system known as invasomes (NVMs) laden with Mirtazapine for rectal administration. This system could circumvent the confines of orally administered counterparts regarding dose schedules and bioavailability. Mirtazapine invasomes were tailored by amalgamating phospholipid, cineole, and ethanol through a thin-film hydration approach rooted in the Box-Behnken layout. Optimization of composition parameters used to fabricate desired NVMs' physicochemical attributes was undertaken using the Design-Expert® program. The optimal MRZ-NVMs were subsequently transformed to a pH-triggered in situ rectal gel followed by animal pharmacodynamic and pharmacokinetic investigations relative to rectal plain gel and oral suspension. The optimized NVMs revealed a diameter size of 201.3 nm, a z potential of -28.8 mV, an entrapment efficiency of 81.45%, a cumulative release within 12 h of 67.29%, and a cumulative daily permeated quantity of 468.68 µg/cm2. Compared to the oral suspension, pharmacokinetic studies revealed a 2.85- and 4.45-fold increase in calculated rectal bioavailability in circulation and brain, respectively. Pharmacodynamic and immunohistopathology evaluations exposed superior MRZ-NVMs attributed to the orally administered drug. Consequently, rectal MRZ-NVMs can potentially be regarded as a prospective nanoplatform with valuable pharmacokinetics and tolerability assets.

Emotion dysregulation in older people: validity and reliability of an 8-item version of the Difficulties in Emotion Regulation Scale

OBJECTIVES

The abbreviated 16-item version of the Difficulties with Emotion Regulation Scale (DERS-16) is widely used to assess individuals' perceived challenges in regulating their emotions, a central aspect of psychological symptoms commonly experienced in old age. However, its psychometric properties have yet to be tested in this population. Furthermore, a shorter version of the DERS-16 could further minimize the assessment burden on older individuals. Thus, we aimed to test the DERS-16's psychometric performance and determine if any items were redundant to develop a psychometrically sound shorter version.

METHODS

We enrolled 302 Portuguese older adults (Mage = 75.22; SD = 8.99 years) in a cross-sectional study.

RESULTS

Exploratory factor analyses indicated a one-factor structure and a four-factor solution with eight items (69.3%-81.9% of the variance observed). The four-factor-8-item solution presented an interpretable structure and demonstrated good reliability values (> 0.70) and construct validity with the Twenty-Item Toronto Alexithymia Scale, Eight-Item Geriatric Depression Scale, and Geriatric Anxiety Inventory (r = 0.66, 0.40, 0.52; p < 0.001).

CONCLUSION

The robust psychometric properties of DERS-8 make it a valuable tool for clinical and longitudinal studies, facilitating targeted interventions in older adults and allowing for precise emotion dysregulation screening.

"A Man Never Cries": A Mixed-Methods Analysis of Gender Differences in Depression and Alcohol Use in Moshi, Tanzania

Background

Unhealthy alcohol use negatively impacts many components of health and wellness, including mental health conditions like major depressive disorder (MDD). Globally, gender differences are common for both alcohol use behaviors and MDD, but these differences have not been studied within Moshi, Tanzania. To provide more effective and culturally appropriate mental health treatments, gender nuances around these conditions must be known. As such, this study aims to explore gender differences in MDD, alcohol use, and other aspects of mental well-being among patients at Kilimanjaro Christian Medical Center (KCMC) in Moshi.

Methods

Six hundred and seventy-six patients presenting for care at the KCMC Emergency Department (ED) and Reproductive Health Centre (RHC) were enrolled in this mixed-methods study between October 2021 and May 2022. Patients were selected through systematic random sampling and completed quantitative surveys including the Alcohol Use Disorder Identification Test (AUDIT) and the Patient Health Questionnaire 9 (PHQ-9). Nineteen patients were purposively chosen from the study population to participate in in-depth interviews (IDIs) exploring topics related to alcohol use, gender, and depression. Descriptive frequencies, univariate log-binomial regressions, and a linear regression model were used to analyze quantitative data, all of which were analyzed in RStudio. A grounded theory approach was used to analyze all IDIs in NVivo.

Results

Average [SD] PHQ-9 scores were 7.22 [5.07] for ED women, 4.91 [4.11] for RHC women, and 3.75 [4.38] among ED men. Similarly, ED women held the highest prevalence of MDD (25%) as compared to RHC women (11%) and ED men (7.9%) (p<0.001). Depressive symptoms were associated with higher AUDIT scores only for ED men (R2 = 0.11, p<0.001). Our qualitative analysis showed that while present for women, social support networks were notably absent for men in Moshi, the lack of which was seen to play a role in alcohol use. For men, alcohol was described as a coping mechanism for stress.

Conclusion

Intersectionality of gender, alcohol use, and depression is influenced by sociocultural and behavioral norms in Moshi. As such, multi-layered, gender-differentiated programming should be considered for the treatment of substance use and mental health conditions in this region.

Depressive symptoms and their association with age, chronic conditions and health status among middle-aged and elderly people in peri-urban Tanzania

Background

Depression is a global mental health challenge. We assessed the prevalence of depressive symptoms and their association with age, chronic conditions, and health status among middle-aged and elderly people in peri-urban Dar es Salaam, Tanzania.

Methods

Depressive symptoms were measured in 2,220 adults aged over 40 years from two wards of Dar es Salaam using the ten-item version of the Center of Epidemiologic Studies Depression Scale (CES-D-10) and a cut-off score of 10 or higher. The associations of depressive symptoms with age, 13 common chronic conditions, multimorbidity, self-rated health and any limitation in six activities of daily living were examined in univariable and multivariable logistic regressions.

Results

The estimated prevalence of depressive symptoms was 30.7% (95% CI 28.5-32.9). In univariable regressions, belonging to age groups 45-49 years (OR 1.35 [95% CI 1.04-1.75]) and over 70 years (OR 2.35 [95% CI 1.66-3.33]), chronic conditions, including ischemic heart disease (OR 3.43 [95% CI 2.64-4.46]), tuberculosis (OR 2.42 [95% CI 1.64-3.57]), signs of cognitive problems (OR 1.90 [95% CI 1.35-2.67]), stroke (OR 1.56 [95% CI 1.05-2.32]) and anemia (OR 1.32 [95% CI 1.01-1.71]) and limitations in activities of daily living (OR 1.35 [95% CI 1.07-1.70]) increased the odds of depressive symptoms. Reporting good or very good health was associated with lower odds of depressive symptoms (OR 0.48 [95% CI 0.35-0.66]). Ischemic heart disease and tuberculosis remained independent predictors of depressive symptoms in multivariable regressions.

Conclusion

Depressive symptoms affected almost one in three people aged over 40 years. Their prevalence differed across age groups and was moderated by chronic conditions, health status and socioeconomic factors.

Cognitive Impairment and the Associated Factors Among Older People in Rural Central Tanzania

AIM

This study examined the profile of cognitive impairment and associated factors among older people in rural central Tanzania.

METHODS

We conducted a cross-sectional study involving 462 community-dwelling older adults. We performed cognitive, psychosocial, and clinical assessments and face-to-face interviews with all older adults. Descriptive, bivariate and multivariate linear regression analyses were performed to determine the participant's cognitive performance and the associated factors.

RESULTS

The mean cognitive score on the Identification and Intervention for Dementia in Elderly Africans cognitive test was 11.04 (SD=2.89). Per the proposed cut-off scores to define probable and possible dementia, 13.2% of the population had probable dementia and another 13.9% had possible dementia. Increase in age was associated with poor cognitive performance (β=-0.076, 95% CI=-0.109 to -0.043, P<0.001); whereas male sex (β=0.989, 95% CI=0.333 to 1.645, P=0.003), higher educational attainment (β=2.575, 95% CI=0.557 to 4.594, P=0.013) and performance in instrumental activities of daily living (β=0.552, 95% CI=0.376 to 0.729, P<0.001) were associated with higher cognitive performance.

DISCUSSION

Older people in rural settings of central Tanzania have poor cognitive functions and are at high risk of further cognitive decline. Preventive and therapeutic programs for the affected older people are warranted to prevent further decline and maintain quality of life.

Association of depression and epilepsy in Rwanda: A prospective longitudinal study

INTRODUCTION

Depression is the most common psychiatric comorbidity for persons living with epilepsy. In Rwanda, the prevalence of epilepsy and depression are high, with 4,9% and 13.0% respectively. This prospective interventional study aimed to determine the prevalence and incidence of depression and the outcome of persons living with epilepsy (PwE) with depression attending the outpatient neurology department of a tertiary center.

METHODS

Persons living with epilepsy enrolled between February and June 2018 in a screening cohort with a 12-month follow-up. At every 3-month study visit, PwE were screened for depression using the Patient Health Questionnaire (PHQ-9) questionnaire. Any positively screened subject was administered the Hamilton Depression Rating Scale (HDRS) to confirm the diagnosis and severity of depression. Subjects with moderate to severe depression (MSD), were started on treatment and were followed for another year. We describe the prevalence and incidence of depression, baseline characteristics, epilepsy and depression outcomes, and changes in PGI-C.

RESULTS

Of 572 PwE enrolled, 46 were diagnosed with MSD in a twelve-month period, resulting in an incidence of MSD of 32.7/1000 patient-years. The prevalence of any depression and MSD was 14.2% and 4.7%, respectively. Longer epilepsy duration and seizure status at baseline were associated with MSD. Significant improvements in PGI-C and seizure frequency were observed after treatment optimization.

CONCLUSION

The use of PHQ-9 and HDRS proved successful in identifying depression in PwE. Combined treatment of epilepsy and depression resulted in improved outcomes, warranting the implementation of depression screening every six months in daily neurology practice.

Prevalence and factors associated with depression among older adults in the case of a low-income country, Ethiopia: a systematic review and meta-analysis

BACKGROUND

Depression is among the common mental health problems in late-life and an important public health problem. Studies from both middle- and high-income countries have shown that depression is more common among older people than in adolescents. Many older people with depression are overlooked, and fewer efforts are made to mitigate their suffering. Despite depression being a major public health problem among older adults, its overall magnitude, and its main predictors were not determined for the development of appropriate measures. Hence, the objective of this study was, therefore, to estimate the overall prevalence of depression and identify its predictors among older adults in Ethiopia.

METHODS

Available articles were searched by means of different databases using the PRISMA guideline. The quality of the included studies was assessed using a JBI quality appraisal tool. STATA version 14.0 (STATA Corporation, College Station, Texas, USA) statistical software was used to analyze the eligible studies. Subgroup and sensitivity analyses were performed. Cochran's Q and the I2 test were used to assess heterogeneity. The presence of publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots.

RESULT

In this meta-analysis, we included 11 articles that assessed 6521 older adults. The overall prevalence of depression among older adults in Ethiopia was 41.85 (33.52, 50.18). The finding was higher in the Oromia region with a prevalence of 48.07% (95% CI: 35.62, 60.51). The finding also demonstrated that being female (AOR = 1.76, 95% CI: 1.17, 2.63), no formal education (AOR = 1.82, 95% CI: 1.03, 3.19), with chronic diseases (AOR = 2.46, 95% CI: 1.00-6.06), and no social support (AOR = 2.01, 95% CI: 1.06, 3.83) were found to be independent predictors of depression in older Ethiopian adults.

CONCLUSION

Our systematic review and meta-analysis showed that almost two out of five older adults had depression. Female sex, no formal education, having chronic diseases, and no social support were the independent predictors of depression among older adults in Ethiopia. The study emphasizes that depression among older adults in Ethiopia calls for appropriate screening and interventions to reduce the occurrence and its overwhelming consequences.

Depression and associated factors among older adults in Bahir Dar city administration, Northwest Ethiopia, 2020: Cross-sectional study

Background

Depression is the most common psychiatric condition among older adults, and it goes unnoticed by individuals themselves and is under-diagnosed by clinicians due to the misconception that these are normal parts of aging. However, the problem is not properly addressed in Ethiopia. This study aimed to determine the prevalence and associated factors of depression among the older adults in Bahir Dar city.

Methods

A community-based cross-sectional survey was conducted among 423 older adults in Bahir Dar city. A simple random sampling technique was used to select the study participants. Depression was assessed using a 15-item Geriatric Depression Scale (GDS). A multivariable logistic regression analysis was used to explore the potential determinants of depression among the participants.

Results

The prevalence of depression among older adults was found to be 57.9% (95% CI: 53.2–62.6). This study showed that educational status with grades 5-8^th (AOR: 5.72, 95% CI: 2.87–11.34), and 9-12^th grade (AOR: 3.44, 95% CI: 1.59–7.41), income <2004 ETB (AOR = 1.89, 95% CI: 1.16–3.07), cognitive impairments (AOR: 3.54, 95% CI: 2.16–5.81), family history of mental illness (AOR:3.06, 95% CI: 1.03–9.04), and poor quality of life (AOR: 2.78, 95% CI: 1.74–4.46) were significantly associated with depression.

Conclusion

The prevalence of depression among older adults was found to be huge. Having low educational status, low monthly income, cognitive impairments, family history of mental illness, and poor quality of life were associated with depression. Therefore, raising community awareness of mental health, increasing social participation, providing supportive counseling and routine screening of depressive symptoms are essential in combating depression among Bahir-Dar city older adults.

The mediation role of sleep quality in the relationship between cognitive decline and depression

Objectives

Associations between cognitive decline and depression have been inconclusive. We examined 1) whether sleep quality mediates these relationships and 2) which factor of sleep quality mediates these relationships.

Methods

This study utilized baseline data from the 2018 West China Health and Aging Trend study (WCHAT), a large cohort data-set that including participants aged over 50 years old. We defined depression using the 15-item Geriatric Depression Scale (GDS-15). Cognitive status was measured using the Short Portable Mental Status Questionnaire (SPMSQ) and sleep quality was assessed using the Pittsburgh sleep quality index (PSQI). Direct relationships between cognitive decline, sleep quality and depression were assessed using multiple linear regression. Mediation models and structural equation model (SEM) pathway analysis were used to test the mediating role of specific aspects of sleep (e.g., quality, duration) in the relationship between cognitive decline and depression.

Results

Of 6828 participants aged 50 years old or older, the proportion of depression was 17.4%. Regression analysis indicated a total association between cognitive scores (β = 0.251, 95% CI 0.211 to 0.290, p < 0.001) and depression status. After adjusted PSQI scores, the association between cognitive scores and depression status was still significant (β = 0.242, 95% CI 0.203 to 0.281, p < 0.001), indicating a partial mediation effect of sleep quality. Mediation analysis verified sleep quality partially mediate the associations between cognitive decline and depression (indirect effect estimate = 0.0308, bootstrap 95% CI 0.023 to 0.040; direct effect estimate = 0.3124, bootstrap 95% CI 0.269 to 0.350). And daytime dysfunction had a highest mediation effect with a proportion of mediation up to 14.6%.

Conclusions

Sleep quality partially mediated the relationship between cognitive decline and depression. Daytime dysfunction had a highest mediation effect. Further research is necessary to examine the effects of sleep quality on the relationship of cognitive decline and depression.
