Prevalence and associations of depression among patients with cardiac diseases in a public health institute in Trinidad and Tobago

The Role of Neuroinflammation in the Comorbidity of Psychiatric Disorders and Internal Diseases

Psychiatric disorders and internal diseases frequently co-occur, posing significant challenges due to overlapping symptoms, shared pathophysiological mechanisms, and increased healthcare burdens. Neuroinflammation has emerged as a central mechanism linking these conditions, driven by systemic inflammation, hypothalamic-pituitary-adrenal (HPA) axis dysregulation, and autonomic nervous system (ANS) imbalance. This review synthesizes current evidence on the role of neuroinflammation in comorbid conditions such as depression, anxiety, cardiovascular disease, and diabetes mellitus, emphasizing bidirectional relationships and shared inflammatory pathways. This analysis identifies gaps in longitudinal studies, biomarker validation, and the integration of multidisciplinary care models. Emerging therapeutic approaches, including IL-6 inhibitors, vagus nerve stimulation, and behavioral interventions, show promise but remain underexplored in combined applications. Furthermore, disparities in research representation limit the generalizability of findings and highlight the need for inclusive clinical trials. Addressing these gaps through precision medicine, advanced biomarker monitoring technologies, and equitable healthcare strategies could transform the management of these complex comorbidities. By advancing our understanding of neuroinflammatory mechanisms and promoting integrated interventions, this review underscores the need for a collaborative, patient-centered approach to improve outcomes and reduce the global burden of psychiatric and internal disease comorbidities.

Psychosocial Well-Being Among Adult Residents of Flood-Prone Communities in Trinidad: Associated Factors and Predictors in a Cross-Sectional Study

Background Globally, flooding is one of the severe consequences of climate change, which is exacerbated by urbanization and inadequate infrastructure. In Trinidad and Tobago, floods affect a sizable proportion of the population and pose a major public health hazard. Aim This study assessed the psychosocial impact of flooding on adult residents in flood-prone areas of Trinidad and Tobago, focusing on the prevalence of mental health conditions such as depression, anxiety, stress, and post-traumatic stress disorder (PTSD), along with identifying associated factors and predictors of psychological distress. Methods Convenience sampling was used to collect data from 215 adult household residents in four selected flood-prone areas in Trinidad and Tobago over 12 weeks, from January 2024 to March 2024. The inclusion criteria were being at least 18 years of age, having resided in their area for at least two consecutive years prior to the start date of the study, and having experienced at least one severe flood in the two years prior to the start date. The data collection instrument was a questionnaire, which was chosen to ensure broad accessibility and ease of data collection in the selected flood-prone areas. The variables measured included selected sociodemographic characteristics, household medical history, and flood characteristics. The 36 items also included the following: (1) the Patient Health Questionnaire-2, (2) the Generalized Anxiety Disorder 2-item, (3) the Perceived Stress Scale 4, and (4) the Posttraumatic Stress Disorder Checklist. In this study, the nature of flooding was categorized ordinally as none, mild, moderate, and severe, in keeping with the flood classifications in Queensland in 2020. Descriptive and inferential statistical methods were used for data analysis. Results Of the 215 residents, 154 (71.6%) met the eligibility criteria and were invited to complete the online questionnaire. Participants were primarily female (n = 162, or 75.3%), predominantly Indo-Trinbagonians (n = 136, or 63.3%), and had a university or college education (n = 129, or 60%). Among the victims, 127 (82.5%) needed to be evacuated. More than four-fifths (82.5%) of those who experienced flooding were classified as having moderate-to-severe stress, with "Age group" being a key predictor; slightly over half (53.2%) experienced no depression, and 56.5% experienced no anxiety. The reported psychological symptoms included mild depression (34.4%), mild anxiety (36.4%), and mild PTSD (38.3%). The differences between or among mean psychological symptom scores were not significant for any sociodemographic variable. However, "Need to evacuate," "Age group," "Flood duration," and "Flood severity" were associated with at least one of anxiety, PTSD, and stress (p < 0.05). Ordinal logistic regression showed that (1) "Need to evacuate" was a predictor of anxiety, (2) "Flood severity" and "Need to evacuate" were predictors of PTSD, and (3) "Age group" was the only predictor of stress. These findings suggest that evacuation may serve as a critical stressor leading to higher anxiety and PTSD symptoms. Conclusion Flood victims experienced significant psychosocial problems with stress, followed by PTSD as the most common disorder. Implementing targeted psychological support and community preparedness programs could mitigate the psychosocial effects of flooding. Follow-up studies with broader populations are needed to help assist in further subgroup analysis.

The Association between Depression and Heart Attack: Examining Demographic and Behavioral Correlates in Tennessee

Background

Cardiovascular diseases (CVD) and depression are growing global health concerns as heart attack and stroke solely account for around 85% of total CVD deaths and 280 million ie, while 3.4% of the world's population have depression. A bi-directional relationship exists between depression and heart disease: about one-fourth of heart disease patients experience depression, and those with depression have a higher risk of developing heart disease compared to the general population. This study aims to examine the association between depression and heart attack as a dependent variable, focusing on demographic and behavioral correlates of individuals in Tennessee.

Methods

We performed a cross-sectional analysis using the 2022 Behavior Risk Factor Surveillance System (BRFSS) data for Tennessee (N = 5266). Our analytical approaches involved descriptive and multivariate analysis (logistic regression analysis) to assess the association between depression and heart attack in Tennessee. The primary dependent variable of interest was a self-reported lifetime heart attack and independent variables included self-reported lifetime depression, no exercise in the past 30 days, smoking status, race/ethnicity, gender, and age category.

Results

A total of 7.5% (N = 731) of participants reported lifetime heart attack and 27.8% (N = 828) of participants reported depression. Depression was found to be significantly associated with higher odds of a heart attack (AOR = 1.36; 95% CI, 1.06, 1.73), p < 0.001). Similarly, no exercise in the past 30 days (AOR = 1.74; 95% CI, 1.39, 2.20, p < 0.001) was also associated with higher odds of a heart attack. Furthermore, low income, current smoking status, and race/ethnicity were not found to be significantly associated with heart attack in our study.

Conclusion

This study reinforces the significant link between depression and heart attack while highlighting the complex interplay of demographic and behavioral factors influencing onset of cardiovascular diseases. The findings underscore the necessity for a comprehensive approach to cardiovascular health that integrates mental health considerations and addresses broader social determinants of health.

Long-term impacts of socioeconomic status and childhood trauma on depression in older adults: social work strategies

This study explores the impact of life course socioeconomic status (SES) and childhood trauma on depressive symptoms in Chinese middle-aged and older adults, while also examining the role of chronic diseases and implications for social work practice. Using data from 9,942 participants, structural equation was established to investigate these relationships. Results reveals that low childhood SES positively affects depressive symptoms through low SES in mid-to-late life (std. β = 0.168, p < .001), and domestic child abuse negatively impacts depressive symptoms through low SES in mid-to-late life (std. β=-0.020, p < .001). Additionally, experiencing peer bullying is directly associated with depressive symptoms (std. β = 0.145, p < .001). Exposure to domestic violence is directly related to depressive symptoms (std. β = 0.078, p < .001) and indirectly leads to more severe depressive symptoms through chronic disease (std. β = 0.023, p < .001). Social workers in healthcare settings can utilize these findings to better understand risk factors for depression and provide trauma-informed care and economic assistance across the life course. Additional training for social workers on the lasting impacts of childhood adversity is warranted. By intervening at both individual and policy levels, social work practitioners can help break cycles of poverty and poor health stemming from childhood.

Examining the influence of anxiety and depression on medication adherence among patients diagnosed with acute myocardial infarction

BACKGROUND

Effective medication adherence is vital for managing acute myocardial infarction (AMI) and enhancing patient well-being. This study aimed to evaluate medication adherence levels and associated factors among AMI patients using standardized assessment tools.

METHODS

Employing a cross-sectional descriptive design, the study involved 210 patients diagnosed with acute myocardial infarction. Participants completed the General Medication Adherence Scale (GMAS), Hospital Anxiety and Depression Scale (HADS), and provided socio-demographic details.

RESULTS

The study revealed partial adherence to medications among AMI patients, with mean scores of 24.89 (± 3.64) out of 33. Notably, good adherence was observed in non-adherence due to patient behavior (mean ± SD = 11.8 ± 2.3 out of 15) and additional disease burden (mean ± SD = 8.65 ± 2.21 out of 12), while partial adherence was noted in non-adherence due to financial constraints (mean ± SD = 4.44 ± 1.34 out of 6). Patients reported mild anxiety (mean ± SD = 8.38 ± 2.81) and no depressive symptoms (mean ± SD = 7.43 ± 2.42). Multiple linear regression analysis indicated that employed status, younger age, shorter duration of MI, lower anxiety, and depression levels were associated with higher medication adherence. However, factors such as monthly income, gender, educational level, and marital status did not predict medication adherence.

CONCLUSION

The study highlights the significance of addressing anxiety and depression levels and considering socio-demographic factors when designing interventions to enhance medication adherence among AMI patients. Further research is needed to explore additional determinants of medication adherence and develop tailored interventions to improve patient outcomes post-AMI.

Mindfulness-based intervention for hypertension patients with depression and/or anxiety in the community: a randomized controlled trial

OBJECTIVE

To evaluate mindfulness-based intervention for hypertension with depression and/or anxiety.

METHODS

10-week mindfulness-based intervention, including health education for hypertension, exclusively for the control group, was administered to the intervention group to assist sixty hypertension patients with depression/anxiety. Among them, the intervention group comprised 8 men and 22 women, with a mean age of 60.02 years and a mean duration of hypertension of 6.29 years. The control group consisted of 14 men and 16 women with a mean age of 57.68 years and a mean duration of hypertension of 6.32 years. The severity of depressive and/or anxiety symptoms was assessed using the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder scale (GAD-7), along with blood pressure (BP) measurements taken twice daily. The study utilized a self-made self-efficacy scale and awareness of physical and mental health to evaluate mental health and state.

RESULTS

The depression PHQ-9 or GAD-7 scores reduced by 21.1% or 17.8% in the mindfulness-based intervention group, compared to the control (Z = -2.040, P = 0.041) post 10-week period, suggesting significant reduction in anxiety/stress. These results were consistent with a reduction in systolic BP of 12.24 mm Hg (t = 6.041, P = 0.000). The self-efficacy score of the mindfulness intervention group significantly improved compared to the control (t = 7.818, P < 0.001), while the awareness of physical and mental health in the mindfulness intervention group significantly improved compared to the control (χ2 = 5.781, P = 0.016).

CONCLUSION

Mindfulness-based, short-term focused interventions provide modest relief for depression and/or anxiety and are effective in lowering blood pressure and improving self-efficacy scores.

Cardiovascular Disease in the Caribbean: Risk Factor Trends, Care and Outcomes Still Far From Expectations

Cardiovascular diseases (CVD) are a major public health concern in the Caribbean. Cardiovascular care in the Caribbean revealed encouraging improvements but still less than expectations. This study aims to gain insight into CVD and identify gaps in cardiovascular care in the Caribbean compared to high-income countries. More specifically, this review reports on the epidemiology, CVD risk factors, management practices, and patient outcomes (quality of life (QOL) and mortality). A systematic review of peer-reviewed articles was conducted to assess the CVD of individuals in the Caribbean from 1959 to 2022.Using multiple search engines and keywords, a systematic review of relevant peer-reviewed CVD articles was conducted using the necessary inclusion and exclusion criteria. Relevant data of studies were classified by title, publication year, location, type and size of samples, and results. Further analysis grouped patients by epidemiological profile, CVD risk, management, and selected outcomes (quality of life and inpatient mortality).  From the initial review of 1,553 articles, 36 were analyzed from Trinidad and Tobago (20), Barbados (4), Jamaica (7), along with the Bahamas (2), British Virgin Islands (1), Bonaire (1), and one article from a Caribbean study. The social environment of fast food, sedentary jobs, and stress determinants are postulated to be precursors for an increase in CV risks. CVD in the Caribbean reveals a high prevalence of CV risks, suboptimal care, poor compliance, and high inpatient mortality compared with high-income countries. Greater efforts are required to improve CVD care at all stages, including in the social environment.

Depression and Physical activity among cardiac patients undergone cardiac events: a correlational study

Objective

To assess prevalence of depression and its relationship with physical activity among individuals who have experienced a cardiac event.

Methods

This descriptive study involved 196 cardiac patients receiving treatment at selected cardiac hospitals of Punjab (India). Subjects were chosen using purposive sampling technique. After getting informed written consents from the participants the data was collected using International Physical Activity Questionnaire (IPAQ) and Beck Depression Inventory-II (BDI-II).

Results

The results showed that majority (62.2%) of the cardiac patients had moderate clinical depression and 11.2% of patients had severe depression. 86.7% of the patients had low level of physical activity (<600 MET min/week). There was also a significant negative correlation between the depression and physical activity depicting the higher the physical activity, lower was the depression score and vice-versa (p<0.05). Moreover, study results revealed that physical activity was significantly associated with age and educational status; whereas, depression was not associated with selected demographic variables.

Conclusion

The current investigation has brought to light that a vast majority of individuals suffering from cardiac issues exhibited signs of moderate to severe depressive symptoms. Additionally, the findings indicate an inverse relationship between depression and physical activity. Consequently, it is crucial for nurses to concentrate on identifying early indicators of depression and physical inactivity so that individualized care plans can be developed to enhance the overall health of cardiac patients.

Mental Health in Coronary Heart Disease (CHD) Patients: Findings from the UK Household Longitudinal Study (UKHLS)

OBJECTIVES

Mental health conditions in patients with coronary heart disease (CHD) are closely related to clinical outcomes. Thus, this study's goal is to investigate how CHD affects general and specific aspects of mental health.

METHODS

We analyzed data from Wave 10 Understanding Society: the UK Household Longitudinal Study (UKHLS), which were collected between 2018 and 2019. After removing people who had missing data, there were 450 participants who indicated that they have CHD, and 6138 age- and sex-matched healthy participants indicated that they were not clinically diagnosed with CHD.

RESULTS

The main findings were that participants with CHD had more mental health problems, as shown by the GHQ-12 summary score (t (449) = 6.00, p < 0.001, 95% C.I. [0.20, 0.40], Cohen's d = 0.30), social dysfunction and anhedonia, (t (449) = 5.79, p < 0.001, 95% C.I. [0.20, 0.40], Cohen's d = 0.30), depression and anxiety (t (449) = 5.04, p < 0.001, 95% C.I. [0.15, 0.33], Cohen's d = 0.24), and loss of confidence (t (449) = 4.46, p < 0.001, 95% C.I. [0.11, 0.30], Cohen's d = 0.21).

CONCLUSION

This study implies that GHQ-12 is a valid assessment of mental health problems in CHD patients, and there is a need to consider how different aspects of mental health are affected by CHD rather than solely focusing on depression or anxiety problems alone in patients with CHD.

The Prevalence of Depression and Anxiety in Heart Failure Patients in Saudi Arabia: An Original Study

Background Depression is a severe comorbidity that is often detected in patients with chronic diseases. Poor prognosis may eventuate high mortality risk. Up to 30% of heart failure patients have been documented with depression and the majority upholds depression-related symptoms that may have serious clinical implications, such as hospital readmissions and fatalities. To mitigate depression-induced harms among heart failure patients, studies are being conducted to determine the prevalence, risk factors, and interventions. Objectives The current investigation is envisioned to examine the prevalence of depression and anxiety among the Saudi heart failure population. Also, it will help to explore the risk factors that will subsequently facilitate the analysis of preventive measures. Methodology The cross-sectional epidemiologic research was conducted at King Khalid University, Hospital with the recruitment of 205 participants. Each participant underwent a 30-question screening for depression, anxiety, and related risk factors. The "Hospital, Anxiety, and Depression Scale" (HADS score) was used to score subjects for the assessment of both comorbidities. The data points were subsequently analyzed by descriptive statistics and regression analysis. Results Among 205 participants, 137 (66.82%) were male and 68 (33.17%) were female with a mean age of 59.71 years. Our sample reflects a prevalence of 52.7% depression and 56.9% anxiety in Saudi heart failure patients. High depression scores were positively related to age, female gender, hospital readmissions, and pre-existing comorbidities in heart failure patients. Conclusion The study manifested high depression scores among the Saudi heart failure cohort compared to the previous survey. In addition, a substantial interrelationship of depression and categorical variables has been identified that accentuates predominating risks that can potentially promote depression and anxiety in heart failure patients.

Psychosocial factors correlate with adherence to medications among cardiovascular outpatient clinics in Jordan

BACKGROUND

Adherence to medications is a significant element of self-care behaviors for patients with cardiovascular diseases (CVDs). Non-adherence to cardiovascular medications is the major risk for poor outcomes following any cardiac event. However, there is a lack of studies that addressed medication adherence among patients with CVDs attending outpatient clinics in Arabic countries, including Jordan. Thus, this study purposed to assess the psychosocial factors (e.g. depression, anxiety, stress, social support and self-esteem) and their correlation with adherence to medications among patients with CVDs attending outpatient clinics in Jordan.

METHODS

A total of 395 Jordanian patients attending CVDs outpatient clinics at government, military and private healthcare facilities were recruited.

RESULTS

Our study findings showed that 31.4% of the patients reported complete adherence to their medications. The proportion of psychological reactions reported by the participants was 72.1% for depressive symptoms, 62.6% for anxiety and 50.1% for stress; 79.7% had moderate and normal social support, and 44% had low self-esteem. Depression, anxiety and stress had a significant negative correlation with adherence to medications; however, self-esteem had a significant positive relationship with adherence to medications. In addition, depression, anxiety and stress were the main predictors of adherence to medications.

CONCLUSION

Our findings might aid in paving the road for designing and developing strategies and interventions to increase adherence to medications and minimize these psychosocial problems among CVD patients in outpatient clinics.

Global prevalence of depression, anxiety, and stress in cardiac patients: A systematic review and meta-analysis

BACKGROUND

Cardiovascular disease is one of the most common chronic and life-threatening diseases. Due to the changes made in the normal living conditions of people after suffering from cardiovascular diseases, the appearance of symptoms of depression, anxiety, and stress is common among these patients. The results of the studies show the different prevalence of these disorders, so this study aimed to standardize the global prevalence of depression, anxiety, and stress in Cardiac patients by a systematic review and meta-analysis approach.

METHODS

The present systematic review and meta-analysis were conducted from 2000 to 2022. National and international databases were considered to retrieve related studies, including SID, Magiran, Scopus, Embase, PubMed, and Web of Science (WoS). Joanna Briggs Institute (JBI) checklist was used to evaluate studies qualitatively. Heterogeneity between studies was assessed by I2 index, and data analysis was performed in Comprehensive Meta-Analysis software.

RESULTS

After reviewing the retrieved studies, finally 68 studies on the prevalence of depression with a sample size of 110,219, 36 studies on the prevalence of anxiety with a sample size of 72,374 and 5 studies on the prevalence of stress with a sample size of 533 considered for the meta-analysis. Based on the results of the Meta-Analysis, the overall estimation of the prevalence of depression was 31.3 % (95 % confidence interval: 25.4/0.38 %), anxiety prevalence; 32.9 % (95 % confidence interval: 21.9-46.6 %) and stress prevalence was 57.7 % (95 % confidence interval: 45.3-3.3 %).

CONCLUSION

The result of the present study shows the high prevalence rate of depression, anxiety, and stress in cardiac patients. Therefore, it is recommended that health professionals and policymakers pay more attention to preventing and controlling these disorders.

Magnitude of depression and its associated factors among patients with diabetes mellitus at public hospitals in Southwest Ethiopia, 2021

Depression is the third-leading cause of disability measured in terms of disability-adjusted life-years. When depression coexists with diabetes mellitus, it is associated with major health consequences and results in poor health outcomes, decreased quality of life, lost productivity and increased risk of death. The current study aimed to assess the magnitude of depression and its associated factors among adult patients with diabetes mellitus attending follow-up at the public hospitals of Buno Bedele zone, Southwest Ethiopia. A multi-centre cross-sectional study was done among people living with diabetes mellitus at an outpatient clinic of Buno Bedele zone hospitals. The study period was from April to May 2021. A systematic random sampling technique was used to select the study participants. Data were collected using a structured questionnaire. Depression was assessed by the Patient Health Questionnaire-9. Patient Health Questionnaire-9 is a validated tool to assess depression with sensitivity 86% and specificity 67%. The collected data were cleaned, edited, and entered into epi-data version 3.1, and analysed using SPSS version 24. Logistic regression analysis was employed to identify factors associated with depression occurrence. A p value of 0.05 was considered statistically significant. A total of 310 study participants were included in this study. Among study participants, 41.6% fulfilled the criteria for depression. Variables significantly associated with depression were female gender [AOR: 2.26, 95% CI (1.30, 3.95)], duration of diabetes greater than 5 years [AOR: 2.68, 95% CI (1.57, 4.56)], poor social support [AOR: 2.46, 95% CI (1.10, 5.49)], moderate social support [AOR: 2.63, 95% CI (1.34, 5.16)], current alcohol consumption [AOR: 3.55, 95% CI (1.20, 10.52)] and previous alcohol consumption [AOR = 2.81, 95% CI (1.40, 5.60)]. According to this study, depression is relatively common among diabetic individuals. Being a female, having diabetes for a long time, having poor social support, using alcohol now and in the past were factors that substantially linked to depression. Healthcare professionals should consider screening for depression using the Patient Health Questionnaire-9 or other validated tools in all diabetic patients, especially in those who are at higher risk.

Prevalence Estimates, Severity, and Risk Factors of Depressive Symptoms among Coronary Artery Disease Patients after Ten Days of Percutaneous Coronary Intervention

BACKGROUND

Depression and cardiovascular disorders are significant determinants of health that affect the quality of life and life expectations. Despite the high importance of depression screening among Coronary Artery Disease (CAD) patients, the time being to assess and treat it remains controversial.

OBJECTIVES

This study aims to assess the prevalence estimates and severity of depressive symptoms and determine the risk factors associated with developing such symptoms among CAD patients after ten days of Percutaneous Coronary Intervention (PCI).

METHODS

All patients who underwent elective PCI between October 5, 2019, and Mid-March 2020 and diagnosed with CAD were included in this cross-sectional study. CAD was defined as intra-luminal stenosis of ≥ 50% in one or more of the coronary arteries. Depressive symptoms were screened after ten days of the PCI utilizing the patient health questionnaire-9 (PHQ-9) tool. A linear regression model was used to assess the adjusted effects of independent variables on PHQ-9 scores. Electronic medical records, clinical charts, and PCI and echocardiogram reports were reviewed.

RESULTS

Out of 385 CAD patients, a total of 335 were included in this study, with a response rate of 87%. The participants' mean (±SD) age was 57.5±10.7 years, 75.2% were males, 43% were current smokers, and 73.7% had below bachelor's education. The prevalence estimates of patients with moderate to severe depressive symptoms (PHQ-9 ≥10) was 34%, mild depression 45.1%, and normal 20.9%. Female gender, low educational level and diabetes mellitus were found to be the significant independent predictors of depression among our cohort with (t(333) = 3.68, p<0.001); (t(333) = 5.13, p<0.001); and (t(333) = 2.79, p=0.042), respectively.

CONCLUSION

This study suggests a high prevalence of depressive symptoms among CAD patients after ten days of PCI. Approximately one out of three patients with CAD have significant symptoms of depression, which is an alarming finding for clinicians. Moreover, this study demonstrates a lack of sufficient depression recognition and management in similar study settings. Integration of mental health assessment and treatment among patients with CAD as soon as after PCI is recommended for optimal and effective treatment and to obtain the best outcomes.

Screening for depressive symptoms in cardiovascular patients at a tertiary centre in Trinidad and Tobago: investigation of correlates in the SAD CAT study

BACKGROUND

This study aimed to screen cardiovascular patients for depressive symptoms at a tertiary centre in Trinidad and Tobago; and to determine any significant associations amongst patients' demographics, comorbidities, and cardiovascular medications with depressive symptoms.

METHODS

In this observational, cross-sectional study, patients (n = 1203) were randomly selected from the cardiology outpatient clinics at the Eric Williams Medical Sciences Complex. After meeting selection criteria, informed consent was obtained, and patients were administered a case report form, which included the Patient Health Questionnaire-9 (PHQ-9). Descriptive analyses included frequency, percentage and summary statistics. Inferential analyses included 95% confidence intervals (CIs), independent sample t-test, Fisher's exact test, Chi-square test, and multivariate logistic regression.

RESULTS

The study had a 96% respondent rate, whereby the average age was 62 years old. Slightly less than half were male, and 52.5% were female. Over 90 % of the sample had cardiovascular disease (CVD). One-quarter of the sample had a PHQ-9 score of ≥10, with almost one-fifth having no depressive symptoms. Females, lower levels of education and income were all found to be statistically significant at risk for depressive symptoms (all p-values < 0.001). Comorbidities associated with depressive symptoms included hypertension, prior cerebrovascular events, chronic kidney disease, and chronic obstructive pulmonary disease with odds ratios (ORs) and 95% confidence intervals (CIs) of OR 1.988 (CI 1.414-2.797), OR 1.847 (CI 1.251-2.728), OR 1.872 (CI 1.207-2.902) and OR 1.703 (CI 1.009-2.876) respectively. Only the cardiovascular medication of ticagrelor was found to be significantly associated with depressive symptoms (p-value < 0.001).

CONCLUSIONS

Twenty-five percent of screened cardiovascular patients displayed significant depressive symptoms with a PHQ-9 ≥ 10. This study also highlights the importance of implementing a multidisciplinary approach to managing cardiovascular disease and screening for depressive symptoms in this subpopulation. Further studies are required to validate these findings.

Quality of life among patients with cardiac disease: the impact of comorbid depression

BACKGROUND

Patients with cardiac disease with or without depression may also have major physical and mental problems. This study assesses and compares the quality of life (QOL) of patients with cardiac disease with and without depression and accompanying comorbidities.

METHODS

A cross-sectional study was conducted with a convenience sample of 388 patients with cardiac disease. The 12-item Short-Form (SF-12)-patient was used to measure physical component scale (PCS) and mental component scale (MCS) QOL, and the Patient Health Questionnaire (PHQ-9) was used to measure depression. The Charlson Comorbidity Index was used to estimate 10-year survival probability. Descriptive statistics, analysis of covariance (ANCOVA), chi-square tests, and binary logistic regression were used for analysis.

RESULTS

The prevalence of minimal to mild depression was 65.7% [(95% CI (60.8, 70.4)] and that of moderate to severe depression was 34.3% [95% CI (29.6, 39.2)]. There was no significant association between the level of PHQ-categorised depression and age (p = 0.171), sex (p = 0.079), or ethnicity (p = 0.407). The overall mean PCS and MCS QOL was 32.5 [95% CI (24.4, 40.64)] and 45.4 [95% CI (44.4, 46.4)], respectively, with no significant correlation between PCS and MCS [r (Pearson's) = 0.011; p = 0.830)]. There were QOL differences among the five PHQ categories (PCS: p = 0.028; MCS: p ≤ 0.001) with both MCS and PCS decreasing with increasing depression. ANCOVA (with number of comorbidities as the covariate) showed a significant age × ethnicity interaction for PCS (p = 0.044) and MCS (p = 0.039), respectively. Young Indo-Trinidadians had significantly lower PCS than did Afro-Trinidadians, while the converse was true for MCS. Depression, age, and number of comorbidities were predictors of PCS, while depression, age, and sex were predictors of MCS.

CONCLUSIONS

Increasing severity of depression worsened both PCS and MCS QOL. Age and level of clinical depression predicted QOL, with number of comorbidities predicting only PCS and sex predicting only MCS. Efforts must be made to treat depression in all age groups of patients with cardiac disease.

Socio-demographic characteristics, lifestyle factors, multi-morbid conditions and depressive symptoms among Nepalese older adults

BACKGROUND

Depressive symptoms (DS) are a well-recognized public health problem across the world. There is limited evidence with regard to DS and its associates, such as socio-demographic characteristics, lifestyle factors and chronic conditions in low-income countries like Nepal. In this study, we aimed to assess the level of DS and its relationship with socio-demographic characteristics, lifestyle factors and chronic disease conditions among community dwelling older people in Nepal.

METHODS

We conducted a cross-sectional study of 794 older adults aged 60 or above residing in the rural setting of the Sunsari and Morang districts of eastern Nepal between January and April 2018. Multi-stage cluster sampling was adopted to select the study participants. Data included socio-demographics, lifestyle factors, self-reported chronic disease conditions and the Geriatric depression scale. On Geriatric depression scale, an older adult with a test score greater than five were defined as having depressive symptoms. Determinants of DS were estimated through the generalized estimating equation (GEE) approach by considering exchangeable correlation structure among clusters.

RESULTS

In our study samples, nearly 55.8% of the older adults were found to be suffering from DS. We found a significant association between DS and being female (aOR: 1.25, 95% CI: 0.89-2.09), Buddhism (aOR: 1.95, 95% CI: 1.58-2.42), Dalits (aOR: 2.60, 95% CI: 1.19-5.65), unemployed, low family income (aOR: 1.77, 95% CI: 1.07-2.92), smokers (aOR: 1.49, 95% CI: 1.01-2.20) and having chronic multi-morbid conditions (aOR: 1.67, 95% CI: 1.09-2.55).

CONCLUSIONS

The prevalence of DS was high among community-dwelling older adults in eastern Nepal. Our findings suggest the need for mental health prevention and management programs targeting the older population in rural Nepal.
