Depressive Symptom Frequency and Prevalence of Cardiovascular Diseases—Analysis of Patients in the National Health and Nutrition Examination Survey

Bidirectional association between depression and diabetic nephropathy by meta-analysis

BACKGROUND

Studies suggested that the association between depression and diabetic nephropathy may be bi-directional, but this hypothesis remains investigating. In this meta-analysis, the bi-directional relationship between depression and diabetic nephropathy was investigated.

METHODS

A search for the publications on depression and diabetic nephropathy in the databases of PubMed, Web of science, and Embase from the earliest available to August 2022 was conducted. Two sets of pooled risk estimates were calculated using random effects models: diabetic nephropathy predicting depression and depression predicting diabetic nephropathy. Cross-sectional studies were assessed using Agency for Healthcare Research and Quality (AHRQ), cohort and case-control studies were assessed using Newcastle-Ottawa Scale (NOS).

RESULT

Of the 974,121 patients in 30 clinical studies, 24 studies met eligibility for diabetic nephropathy predicting onset of depression, representing 28,438 incident cases. The other 6 studies met criteria for depression predicting onset of diabetic nephropathy, representing 945,683 incident cases. The pooled odds ratio (OR) of diabetic nephropathy predicting depression was 1.46 (95% CI 1.27-1.67). The OR of depression predicting diabetic nephropathy was 1.22 (95% CI 1.13-1.31).

CONCLUSION

This meta-analysis shows that the relationship between depression and diabetic nephropathy may be bidirectional. Diabetic nephropathy may be a predictor of depression, and depression may also be an indicator of diabetic nephropathy. The mechanisms underlying the bidirectional relationship need to be further investigated and interventions of the comorbidity of depression and diabetic nephropathy need be studied in clinical practice.

Association between level of depression and coronary heart disease, stroke risk and all-cause and cardiovascular mortality: Data from the 2005-2018 National Health and Nutrition Examination Survey

Research on the association between level of depression and coronary heart disease (CHD), stroke risk, and all-cause and cardiovascular mortality is lacking in large-scale or population-based studies incorporating cardiovascular disease (CVD) endpoints. We aim to assess the relationship between the level of a person's depression and their risk of CHD, stroke, and all-cause and cardiovascular mortality. Utilizing data from the United States National Health and Nutrition Examination Survey (NHANES), multicycle cross-sectional design and mortality linkage studies were conducted. The study sample included 30918 participants aged 20-85 years old during the 2005-2018 period. Depression was assessed using the nine-item Patient Health Questionnaire (PHQ-9), with scores of 5, 10, 15, and 20 being the cut-off points for mild, moderate, moderately severe, and severe depression, respectively. A series of weighted logistic regression analyses and Cox proportional hazards models were utilized to examine the relationship between the level of depression with the risk of CHD, stroke, all-cause, and cardiovascular mortality. Trend analyses were conducted by entering the level of depression as a continuous variable and rerunning the corresponding regression models. Weighted logistic regression models consistently indicated a statistically significant association between the level of depression and increased risk of CHD and stroke, and those linear trend tests were statistically significant (P for trend < 0.001). Furthermore, weighted Cox regression analyses consistently indicated that participants who had a more severe degree of depression were at a higher risk of all-cause death, and trend analyses suggested similar results (P for trend < 0.001). Another weighted Cox regression analysis also consistently indicated that except for severe depression, the hazard of cardiovascular death was increased with each additional level increase of depression. Our study confirmed that the level of depression was strongly associated with CHD, stroke, and all-cause and cardiovascular mortality, even after accounting for other factors that could impact risk, including variables of age, gender, ethnicity, income, education, body mass index (BMI), marital, and smoking status.

Malnutrition in all its forms and associated factors affecting the nutritional status of adult rural population in Bangladesh: results from a cross-sectional survey

INTRODUCTION

The burden of malnutrition is widely evaluated in Bangladesh in different contexts. However, most of them determine the influence of sociodemographic factors, which have limited scope for modification and design intervention. This study attempted to determine the prevalence of underweight, overweight and obesity and their modifiable lifestyle predictors in a rural population of Bangladesh.

METHODS

This study was part of a cross-sectional study that applied the WHO Package of Essential Noncommunicable Disease Interventions in a rural area of Bangladesh to assess the burden of diabetes, hypertension and their associated risk factors. Census was used as the sampling technique. Anthropometric measurement and data on sociodemographic characteristics and behavioural risk factors were collected following the standard protocol described in the WHO STEP-wise approach. Analysis included means of continuous variables and multinomial regression of factors.

RESULTS

The mean body mass index of the study population was 21.9 kg/m2. About 20.9% were underweight, 16.4% were overweight and 3.5% were obese. Underweight was most predominant among people above 60 years, while overweight and obesity were predominant among people between 31 and 40 years. Higher overweight and obesity were noted among women. Employment, consumption of added salt and inactivity increased the odds of being underweight by 0.32, 0.33 and 0.14, respectively. On the other hand, the odds of being overweight or obese increased by 0.58, 0.55, 0.78, 0.21 and 0.25 if a respondent was female, literate, married, housewife and consumed red meat, and decreased by 0.38 and 0.18 if a respondent consumed added salt and inadequate amounts of fruits and vegetables, respectively. Consumption of added salt decreases the odds of being overweight or obese by 0.37.

CONCLUSION

The study emphasised malnutrition to be a public health concern in spite of the dynamic sociodemographic scenario. Specific health messages for targeted population may help improve the nutritional status. Findings from further explorations may support policies and programmes in the future.

Inflammatory properties of diet mediate the effect of depressive symptoms on Framingham risk score in men and women: Results from the National Health and Nutrition Examination Survey (2007-2014)

Depression is common in patients with cardiovascular disease (CVD) and associated with inflammation. Inflammation contributes to the development of CVD and can be modulated by diet. However, the role of inflammatory properties of diet in the relationship between depressive symptoms and CVD risk is not well understood. We hypothesized that the inflammatory properties of diet mediate the relationship between depressive symptoms and CVD risk in men and women. Cross-sectional data collected by the National Health and Nutrition Examination Survey (2007-2014) were used for the study. Depressive symptoms scores, inflammatory properties of diet, and CVD risk were measured by the Patient Health Questionnaire-9 (PHQ-9), the Dietary Inflammatory Index (DII), and the Framingham risk score (FRS), respectively. Generalized linear models were used for the mediation analysis. There were significant differences in the proportions of men and women in the depressed group (PHQ-9 ≥ 10; 5.24 ± 0.65% vs 9.36 ± 0.87%, P < .001) and high CVD risk group (FRS >20%; 16.47 ± 0.79% vs 6.03 ± 0.32%, P < .001). The DII partially mediated the relationship between depressive symptoms and CVD risk in men (indirect effect: 0.06, P = .010) but fully mediated the relationship between depressive symptoms and CVD risk in women (indirect effect: 0.10, P < .001). These findings confirmed our hypothesis that inflammatory properties of diet at least partially mediate the relationship between depressive symptoms and CVD risk in men and women. Our findings suggest that interventions designed to reduce depressive symptoms should contain strategies to reduce pro-inflammatory and increase anti-inflammatory properties of diet to decrease CVD risk.

Bidirectional association between depressive symptoms and carotid atherosclerosis in community-based older adults in China

We explored the bidirectional association between depressive symptoms and measures of carotid atherosclerosis. This study included 1155 participants aged 55 years and older. Depressive symptoms was assessed by 30-item Geriatric Depression Scale (GDS-30) score. Common carotid artery intima-media thickness (CCA-IMT), carotid plaques and carotid stenosis were measured at both common carotid arteries using an edge detection system. In part 1, we explored the risk of CCA-IMT on depressive symptoms. We identified a significantly increased risk of depressive symptoms with the severity of carotid atherosclerosis. ORs (95%CI) of CCA-IMT thickening, carotid plaque and carotid stenosis for depressive symptoms were 1.48(0.72-3.03), 2(1.03-3.85) and 5.29(2.16-12.97) comparing with normal CCA-IMT in adjusting all potential risk factors models. When using carotid atherosclerosis as a continuous variable, the OR for depressive symptoms was 1.32 (95%CI 1.16-1.49) with every 0.1mm elevated in CCA-IMT after adjustment for all potential confounders. In part 2, we explored the risk of depressive symptoms on carotid atherosclerosis. We found elevated depressive symptoms significantly increased the risk of carotid atherosclerosis in multi-factor adjusted models [OR (95%CI): 1.65(1.10-2.47)]. When using depressive symptoms as a continuous variable, the ORs for carotid artery atherosclerosis were 1.32 (95%CI 1.16-1.49) with every 1 GDS-30 score elevated after adjustment for all convenient risk factors. The current study demonstrated the bidirectional links of carotid atherosclerosis measures with depressive symptoms. More cohort study and clinical trial focusing on the issue need to be explored in the future.

Relationship between diabetic nephropathy and depression: a cross-sectional analysis using the Diabetes Study from the Center of Tokyo Women's Medical University (DIACET)

OBJECTIVE

We conducted this cross-sectional study to investigate the relationship between stage of diabetic nephropathy and likelihood or severity of depression in patients with diabetes.

RESEARCH DESIGN AND METHODS

We studied 2212 patients with diabetes (mean age 60.9 years; 928 women; 1838 patients with type 2 diabetes). Presence and severity of depression was examined using the Patient Health Questionnaire-9 (PHQ-9). Patients were classified into 5 stages of nephropathy, according to albuminuria and estimated glomerular filtration rate (eGFR); patients in stage 5 undergoing dialysis and kidney transplantation were analyzed separately (stages 5D and 5T). The relationship between stage of nephropathy and depression was examined using analysis of covariance and multivariate logistic regression analysis.

RESULTS

Both least square mean PHQ-9 scores and prevalence of patients with PHQ-9 scores ≥5 points (mild depression) and ≥10 points (moderate or severe depression) increased from stage 1 to 5D, and then declined in stage 5T. Multivariate ORs for mild or greater depression increased in patients in stages 3, 4, and 5D in reference to those in stage 1, which declined in patients in stage 5T. Albuminuria was significantly, but eGFR was not, associated with higher PHQ-9 scores and the PHQ-9 scores ≥5 or ≥10 after adjustment for clinical findings.

CONCLUSIONS

In patients with diabetes, progression of nephropathy is likely to be associated with increased risk and severity of depression, which may be reduced after successful kidney transplantation. Albuminuria may be more strongly associated with depression than eGFR.
