Risk Of Elevated Depressive Symptoms Research Articles

Ethylene oxide exposure, inflammatory indicators, and depressive symptoms: a cross-sectional study and mediation analysis based on a non-institutionalized American population.

Ethylene oxide (EO) is a volatile compound positively correlated with respiratory and cardiovascular diseases. Currently, evidence suggests that environmental exposure may contribute to depressive symptoms. This study evaluated the correlation between EO exposure and depressive symptoms and investigated whether inflammatory indicators had a mediation effect on this correlation. Patients were enrolled from the National Health and Nutrition Examination Survey during 2013-2016, and 2,764 (49.67% male and 50.33% female) participants were ultimately included. EO exposure was determined by measuring hemoglobin-EO adduct (Hb-EO) concentration due to its long half-life, which was log2-transformed. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Multivariable logistic regression analysis was performed to identify any correlations before and after covariate adjustment. Sensitivity analysis, subgroup analyses, and interaction tests were performed to further evaluate identified correlations. Mediation analysis was conducted to reveal whether specific inflammatory indicators mediated the correlation. A high prevalence of depressive symptoms was observed in quartiles with increased levels of EO exposure, and male individuals exhibiting higher Hb-EO levels than female individuals. A positive correlation was observed between EO exposure and depressive symptoms (odds ratio [OR]: 1.439, 95% confidence interval [CI]: 1.310, 1.581), which remained stable even after covariate adjustment (OR: 1.332, 95% CI: 1.148, 1.545). Interaction tests showed significant effects of sex (p < 0.001) and thyroid diseases (p = 0.048) on this correlation. In the mediation analysis, white blood cell (p = 0.010) and neutrophil counts (p = 0.010) exerted a mediating effect, accounting for 13.6 and 11.9%, respectively. Increased exposure to EO is associated with an elevated risk of depressive symptoms, where white blood cell and neutrophil counts exert a significant mediating effect. Further prospective studies are required to investigate the potential link among EO, other environmental pollutants, and human mental health.

The impact of internet device diversity on depressive symptoms among middle-aged and older adults in China: A cross-lagged model of social participation as the mediating role

BackgroundDepressive symptoms is more prevalent in middle-aged and older populations, and the development of Internet technology has brought new challenges and opportunities for the mental health of this group. This study aims to explore the bidirectional relationship between Internet device diversity and levels of depressive symptoms through longitudinal data analysis, as well as investigate the mediating role of social participation. MethodsData for the analysis was retrieved from the China Health and Retirement Longitudinal Study (CHARLS) in 2015, 2018, and 2020, which included 9259 middle-aged and older adults. The sum of the number of devices mentioned by each participant was calculated to assess the diversity of internet device use, a weighted total score of how frequently and to what extent individuals had participated in various social activities in the past month was calculated to measure the social engagement, and the Center for Epidemiological Studies Depression Scale was used to calculate depressive symptoms. A cross-lagged mediation model and bivariate correlation analysis were employed to examine the longitudinal relationships among depressive symptoms, internet device diversity, and social participation. Age, gender, highest education level, marital status, drinking status, smoking history, self-rated health, sleep duration, and chronic health conditions were adjusted as covariates. ResultsThe results from the three waves of longitudinal data revealed mutual predictive relationships among internet device diversity, social participation, and depressive symptoms. The mediating effect was significant (β = −0.612, 95 % CI −0.796 to −0.429), with significant gender differences observed. Furthermore, our findings indicated that social participation functioned as a protective factor against depressive symptoms, and the association between social participation and depressive symptoms was not a straightforward linear relationship. This suggests that participation in social activities (either high or low) is associated with a lower risk of depressive symptoms compared to no social participation, with no gender differences. ConclusionsThis study suggests that there is a relationship between internet device diversity and lower levels of depressive symptoms among middle-aged and older adults in China. Social participation mediates the relationship between internet device diversity and depressive symptoms, and different levels of social engagement have different effects on depressive symptoms. It is recommended to increase support for social participation among middle-aged and older adults, strengthen structural social capital, and better leverage the use of the internet to reduce depressive symptoms levels and promote the physical and mental well-being of this population.

Depressive Symptoms and Quality of Life Among Women Living With a Partner Diagnosed With ADHD.

Objective: This study explores the depressive symptoms and quality of life (QoL) of women in relationships with partners diagnosed with ADHD, as well as the role of engagement in health-promoting activities (HPA) on these outcomes, spotlighting the often-neglected perspective of these women. Methods: Employing a cross-sectional approach, the study used Structural Equation Modeling (SEM) to explore associations between partners' ADHD functional impairment, women's involvement in HPA, and their depressive symptoms and QoL. Results: Functional impairment in partners with ADHD was positively associated with women's depressive symptoms and negatively associated with their QoL, whereas women's engagement in HPA was positively associated with their QoL and negatively associated with their depressive symptoms. Conclusions: The findings suggest that women partnered with individuals diagnosed with ADHD may face an elevated risk of depressive symptoms and lowered QoL. The results highlight the potential need for a more comprehensive clinical approach to adult ADHD treatment that considers functional impairments and the experiences of partners. Incorporating HPA into therapeutic strategies appears beneficial. However, longitudinal research is needed to examine the direction of these associations and to develop potential interventions to support these women.

LUTS/BPH increases the risk of depressive symptoms among elderly adults: A 5-year longitudinal evidence from CHARLS

ObjectiveThe prevalence of Lower Urinary Tract Symptoms suggestive of Benign Prostatic Hyperplasia (LUTS/BPH) is notably high and potentially elevates the likelihood of depressive symptoms. This study was designed to employ both cross-sectional and longitudinal methodologies to explore the correlation between LUTS/BPH and depressive symptoms among middle-aged and elderly men in China. MethodsThis investigation utilized data from the China Health and Retirement Longitudinal Study (CHARLS), with the initial dataset from 2015 serving as the baseline and subsequent data from 2018 and 2020 facilitating longitudinal analysis. The study encompassed a baseline cohort of 5156 men aged 45 years and above, and an expansive longitudinal analytical sample of 23,530 participants spanning from 2015 to 2020. The assessment of depressive symptoms was conducted using the 10-item Center for Epidemiological Studies Depressive Symptoms Scale (CESD-10). To investigate the factors associated with LUTS/BPH, the relationship between LUTS/BPH and depressive symptoms, and to evaluate the incidence rate of depressive symptoms onset based on LUTS/BPH status, multivariate logistic analyses and logistic regression models were employed. ResultsOur results reveal a markedly higher incidence of depressive symptoms among individuals with LUTS/BPH, at 30.16 %, compared to 22.94 % in those without LUTS/BPH. This pattern was consistent in both mild and moderate depressive symptoms categories. However, the prevalence of severe depressive symptoms did not exhibit a significant disparity between the two groups. Longitudinal analysis spanning from 2015 through 2018 and 2020 further corroborated these observations. Individuals with LUTS/BPH showed a substantially higher incidence of depressive symptoms across all severity levels compared to those without LUTS/BPH. Specifically, the presence of LUTS/BPH was linked to a 53 % heightened risk of mild depressive symptoms, a 45 % increase in moderate depressive symptoms, and an alarming 229 % surge in severe depressive symptoms risk between 2015 and 2018. Additionally, from 2015 to 2020, there was a 30 % increased risk for mild depressive symptoms, a 41 % rise for moderate depressive symptoms, and a 106 % escalation in the risk of severe depressive symptoms among those with LUTS/BPH. ConclusionIn middle-aged and older Chinese adults, LUTS/BPH were correlated with an elevated risk of depressive symptoms.

The moderating effect of dietary selenium intake on the risk of infertility-associated depressive symptoms in female.

To analyze the associations between infertility or dietary selenium intake and depressive symptoms as well as the role of selenium intake on the association between infertility and depressive symptoms in women. This study retrieved the data of 4949 women from National Health and Nutrition Examination Survey (NHANES) database. Univariable and multivariable weighted logistic regression analyses were applied to assess the associations of selenium intake or infertility with the risk of depressive symptoms as well as the regulation of selenium intake on the risk of depressive symptoms related to infertility. The elevated risk of depressive symptoms was found in participants with infertility (odds ratio [OR] = 1.54, 95% confidence interval [CI]: 1.11-2.15). The risk of depressive symptoms was reduced in women with selenium intake ≥55 μg (OR = 0.64, 95%CI: 0.46-0.90). Compared with women without infertility who had selenium intake <55 μg, those with infertility and had selenium intake <55 μg were associated with elevated risk of depressive symptoms after adjusting for confounding factors (OR = 2.01, 95%CI: 1.03-3.90). The risk of depressive symptoms was not significantly increased in women with infertility who had selenium intake ≥55 μg in comparison with subjects without infertility who had selenium intake ≥55 μg (p > 0.05). Selenium intake regulated the association between infertility and depressive symptoms.

Delineating the impact of childhood traumatic brain injury (TBI) on long-term depressive symptom severity: Does sub-acute brain morphometry prospectively predict 2-year outcome?

Despite evidence of a link between childhood TBI and heightened risk for depressive symptoms, very few studies have examined early risk factors that predict the presence and severity of post-injury depression beyond 1-year post injury. This longitudinal prospective study examined the effect of mild-severe childhood TBI on depressive symptom severity at 2-years post-injury. It also evaluated the potential role of sub-acute brain morphometry and executive function (EF) in prospectively predicting these long-term outcomes. The study involved 81 children and adolescents with TBI, and 40 age-and-sex matched typically developing (TD) controls. Participants underwent high-resolution structural magnetic resonance imaging (MRI) sub-acutely at five weeks post-injury (M = 5.55; SD = 3.05 weeks) and EF assessments were completed at 6-months post-injury. Compared to TD controls, the TBI group had significantly higher overall internalizing symptoms and were significantly more likely to exhibit clinically significant depressive symptoms at 2-year follow-up. The TBI group also displayed significantly lower EF and altered sub-acute brain morphometry in EF-related brain networks, including the default-mode network (DMN), salience network (SN) and central executive network (CEN). Mediation analyses revealed significant indirect effects of CEN morphometry on depression symptom severity, such that lower EF mediated the prospective association between altered CEN morphometry and higher depression symptoms in the TBI group. Parallel mediation analyses including grey matter morphometry of a non-EF brain network (i.e., the mentalising network) were not statistically significant, suggesting some model specificity. The findings indicate that screening for early neurostructural and neurocognitive risk factors may help identify children at elevated risk of depressive symptoms following TBI. For instance, children at greatest risk of post-injury depression symptoms could be identified based in part on neuroimaging of networks implicated in EF and post-acute assessments of executive function, which could support more effective allocation of limited intervention resources.

PERCEIVED HOUSING PROBLEMS AND DEPRESSIVE SYMPTOMS AMONG MIDDLE-AGED AND OLDER AMERICANS

Abstract Background Housing insecurity has been shown to be associated with worse mental health. However, previous studies mostly examined one dimension of housing insecurity (e.g., affordability) and few focused on older adults. This study examined the relationship of perceived housing problems with depressive symptoms among middle-aged and older Americans. Method Longitudinal data from the Health and Retirement Study 2006-2018 were used. A total of 7,285 respondents (aged 50+ at baseline) were followed-up every 4 years. Respondents self-reported the status, severity, and duration of their housing problems. Depressive symptoms were assessed by the Center for Epidemiological Studies-Depression Scale (CESD). Mixed-effect models were used to examine the association between perceived housing problems and depressive symptoms, adjusting for individual-level, household-level, and housing-related confounders. Results About 5%-7% of respondents had housing problems during every study visit and 5.67% of them experienced persistent housing problems over the study period of 12 years. Having housing problems was associated with higher risk of depressive symptoms (IRR=1.30, 95% CI=1.23, 1.36). A dose-response relationship was observed in the severity and duration of housing problems, with greater increase of depressive symptoms risk among those experiencing more severe or longer duration of housing problems. Results were similar when modelling the risk of elevated depressive symptoms using a binary measure (CESD score ≥ 4). Conclusion Perceived housing problems were associated with worse mental health among middle-aged and older Americans. The dose-response pattern highlighted the importance of early intervention and consistent assistance to those experiencing housing problems.

Social jetlag as a predictor of depressive symptoms among Japanese adolescents: Evidence from the Adolescent Sleep Health Epidemiological Cohort

ObjectivesSocial jetlag, a circadian misalignment, has been associated with depressive symptoms in the general and working populations. However, evidence for this association in adolescents is inconsistent. This cross-sectional study aimed to investigate the association between social jetlag and depressive symptoms among Japanese adolescents and to evaluate differences by sex. MethodsThe participants were 1493 students (13.6 ± 0.9years, 52.4% girls) from five junior high schools. Questionnaires, including demographic information and the Munich ChronoType Questionnaire, were distributed. Social jetlag was defined as the difference between midsleep on weekdays and weekends, and was categorized as <0 hour (negative), 0 to <1 hour, 1 to <2 hours, or ≥2 hours. Depressive symptoms were assessed using the Birleson Depression Self-Rating Scale for Children. Multivariate logistic regression was used to estimate the odds ratio with adjustments for potential confounders, such as puberty- and lifestyle-related factors. ResultsThe distribution of students with <0 hour, 0 to <1 hour, 1 to <2 hours, and ≥2 hours of social jetlag was 9.4%, 37.0%, 33.3%, and 20.4%, respectively. The multivariate-adjusted model revealed that social jetlag ≥2 hours and <0 hour were associated with an elevated risk of depressive symptoms among girls and boys, respectively. These associations were nonlinear for both sexes in restricted cubic spline analyses. ConclusionsSocial jetlag is associated with depressive symptoms among adolescents. Specifically, the risk of depressive symptoms increased with positive social jetlag scores for girls and negative social jetlag scores for boys.

"More is better" or "better near the middle"? A U.S.-based individual participant data meta-analysis of socioeconomic status and depressive symptoms.

Socioeconomic status (SES) is a widely researched construct in developmental science, yet less is known concerning relations between SES and adaptive behavior. Specifically, is the relation linear, with higher SES associated with better outcomes, or does the direction of association change at different levels of SES? Our aim was to examine linear ("more is better") and quadratic ("better near the middle") associations between components of SES (i.e., income, years of education, occupational status/prestige) and depressive symptoms (Center for Epidemiologic Studies-Depression Scale), and to explore moderation by developmental period (adolescence, young, middle, and older adulthood), gender/sex (female, male), and race/ethnicity (Asian American, Black, Latinx, multiracial, Native American, White). We hypothesized that there would be more support for a model containing quadratic associations. We conducted a two-stage meta-analytic structural equation model of 60 data sets (27,242 correlations, 498,179 participants) within the United States, accounting for dependencies between correlations, which were identified via the Interuniversity Consortium for Political and Social Research and handled using a two-step approach. Income was quadratically associated with depressive symptoms, but the quadratic model did not explain more variance in depressive symptoms than the linear model. Developmental period and race/ethnicity moderated the associations: Income was quadratically associated with depressive symptoms among middle-aged adults, and years of education were quadratically associated with depressive symptoms among White samples. Our findings suggest that researchers and clinical practitioners should consider the elevated risk of depressive symptoms for individuals from low and high-income backgrounds in the United States.

THE EFFECT OF SUPPLEMENTAL NUTRITION ASSISTANCE PROGRAM GENEROSITY ON DEPRESSIVE SYMPTOMS AMONG OLDER AMERICANS

Abstract Food insecurity has been indicated to associate with more depressive symptoms. Supplemental Nutrition Assistance Program (SNAP) is an established anti-poverty government program that targets food insecurity. The goal of this study was to assess whether SNAP generosity, defined at the state level, impacts the relationship of food insecurity and depressive symptoms among older Americans. We linked state-level SNAP policy data to the individual-level data of older adults (aged 60+) from the longitudinal Health and Retirement Study (Nf12,801). Our study baseline was survey year 2000. A state is considered SNAP generous when it eliminates income/assets limit from its SNAP eligibility criteria. All HRS participants reported their food insecurity status and depressive symptoms biennially. Participants were followed until 2018. We conducted state fixed-effect models adjusted for demographic and health measures. Results indicate household food insecurity was associated with higher risk of elevated depressive symptoms (OR=1.83, 95%CI=1.61, 2.07) from a fixed effect logistic model, and this effect was stronger when living in non-generous states compared with generous states though confidence intervals were too wide to be conclusive (OR_interaction =1.09, 95% CI= 0.83, 1.42). The relative excess risk due to interaction (RERI) was 0.17 (95%CI= -0.30, 0.63). Our study finding suggested that there is no to weak evidence that state-level SNAP generosity may alleviate or offset the risk of depressive symptoms associated with food-insecurity.

Social Isolation and Depressive Symptoms Among Older Adults: A Multiple Bias Analysis Using a Longitudinal Study in Japan

PurposeDespite the potential burden of social isolation on mental health, it is unclear which component of social isolation (living alone, lack of social support, and lack of social participation) is mostly associated with depression among older adults and whether it varies by gender. Moreover, previous observational studies have suffered from several systematic biases such as confounding, misclassification, and selection bias. We thus aimed to investigate the risk of social isolation on subsequent depressive symptoms among older men and women, fully taking account of such systematic biases simultaneously. MethodsThis study included 15,311 adults from a nationwide longitudinal cohort study of older adults aged ≥65 years in Japan. We employed modified Poisson regression models to estimate the adjusted risk ratio (aRR) of elevated depressive symptoms (the Geriatric Depression Scale: ≥5 vs. <5) in 2016 according to the social isolation index (SII) score (0-5 points) in 2013. Non-probabilistic multiple bias analyses with weighting approach and bounding factor were conducted to adjust for possible confounding, exposure misclassification, and selection biases. ResultsThe mean age (SD) of participants was 72.1 (4.9) years. Adults with the SII score ≥2 showed an increased risk of elevated depressive symptoms than those with the SII score <2 (aRR [95% CI] = 1.57 [1.41–1.76]). All components of SII were associated with elevated depressive symptoms except living alone for women. Our multiple bias analysis showed that an unmeasured confounder needed to have at least moderate relationship (RR=2.0-3.0) with both exposure and outcome to explain away the observed association particularly when social isolation status was independently and non-differentially misclassified. ConclusionAmong older adults in Japan, social isolation was associated with an increased risk of elevated depressive symptoms, even after taking account of systematic biases simultaneously. Increasing social connection may mitigate the risk of depression, which should be the subject of future research.

The Association between Serum Neutrophil Gelatinase-Associated Lipocalin and Depression in Patients with Type 2 Diabetes Mellitus

ABSTRACT Background Patients wtih type 2 diabetes mellitus (DM) have an increased risk of depressive symptoms. Whether serum neutrophil gelatinase-associated lipocalin (NGAL) is associated with depressive symptoms in old patients with type 2 DM is still uncertain. Objective We aim to investigate whether serum NGAL levels were associated with elevated risk of depressive symptoms in patients with type 2 DM in an old population. Methods Blood samples from 1012 hospitalized patients were measured for serum NGAL within the first 24 hours after admission. The Center for Epidemiological Studies Depression (CES-D) scale was performed to calculate depressive score. Cox analyses were used to examine the prognostic value of serum NGAL on detecting depressive symptoms during a median period of 5 years (range = 0.3–6.2 years). Results 136 (36.6)% of all subjects have depressive symptoms during the follow-up period. Linear analysis showed that serum NGAL levels at baseline were associated with CES-D score after adjusting for clinically relevant variables in type 2 DM patients (Sβ = 0.118, 95% CI 0.106–0.171, P < .001) but not in non-DM patients (Sβ = 0.025, 95% CI, −0.047–0.083; P = .205). Cox analysis revealed that serum NGAL did have an independent prognostic value on predicting depressive symptoms (HR = 2.247, 95% CI 1.415–3.811, P-trend<0.001, Model 2) in type 2 DM patients but not in non-DM patients (HR = 1.811, 95% CI 1.209–3.292, P-trend = 0.189, Model 2) during follow-up period. Conclusions We found the first evidence that serum NGAL were strongly associated with depressive symptoms in patients with type 2 DM but not in non-DM patients. Further studies are needed to prove the underlying mechanism for the impact of type 2 DM on the association.

A school-based program to prevent depressive symptoms and strengthen well-being among pre-vocational students (Happy Lessons): protocol for a cluster randomized controlled trial and implementation study

BackgroundDepression is one of the leading causes of illness and disability among young people. In the Netherlands, one in twelve Dutch adolescents has experienced depression in the last 12 months. Pre-vocational students are at higher risk for elevated depressive symptoms. Effective interventions, especially for this risk group, are therefore needed to prevent the onset of depression or mitigate the adverse long-term effects of depression. The aim of this study is to examine the effectiveness and implementation of a school-based program Happy Lessons (HL), that aims to prevent depression and promote well-being among pre-vocational students.MethodsA cluster randomized controlled trial (RCT) with students randomized to HL or to care as usual will be conducted. Pre-vocational students in their first or second year (aged 12 to 14) will participate in the study. Subjects in both conditions will complete assessments at baseline and at 3- and 6-months follow-up. The primary outcome will be depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D) at 6-months follow-up. Secondary outcomes are well-being using the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) and life satisfaction (Cantril Ladder) measured at 6-months follow-up. Alongside the trial, an implementation study will be conducted to evaluate the implementation of HL, using both quantitative and qualitative methods (interviews, survey, and classroom observations).DiscussionThe results from both the RCT and implementation study will contribute to the limited evidence base on effective school-based interventions for the prevention of depression and promotion of well-being among pre-vocational adolescents. In addition, insights from the implementation study will aid identifying factors relevant for optimizing the future implementation and scale-up of HL to other schools and contexts.Trial registrationThis study was registered on 20 September 2021 in the Dutch Trial Register (NL9732).

Depressive symptoms in higher education students during the first wave of the COVID-19 pandemic. An examination of the association with various social risk factors across multiple high- and middle-income countries

Higher-education students face substantial risks for developing depressive symptoms during the COVID-19 pandemic or experiencing exacerbated pre-existing depressive symptoms. This study uses data from the COVID-19 International Student Well-Being Study, which collected data through a non-representative convenience sample in 125 higher-education institutions (HEI) across 26 high- and middle-income countries (N: 20,103) during the first wave of the COVID-19 pandemic. It describes the prevalence of depressive symptoms in higher-education students. We find substantial cross-national variation in depressive symptoms, with lowest mean levels established in the Nordic countries and France, while highest mean levels of depressive symptoms were found in Turkey, South Africa, Spain and the USA. Elevated risk for depressive symptoms was found in female students, students with fewer social support resources and in a more disadvantaged socioeconomic position, and students with a migrant background. COVID-19 related stressors, such as reduced social contact, increased financial insecurity, and academic stress explained a relatively larger proportion of the variance in depressive symptoms compared to non-COVID-19 related stressors. This finding shows that not the pandemic itself, but rather the secondary effects of the pandemic relate to students' mental health. Our results enable HEIs to be better equipped to target groups that are particularly at risk during a pandemic.

Allostatic load, unhealthy behaviors, and depressive symptoms in the Hispanic Community Health Study/Study of Latinos.

BackgroundThe Environmental Affordances Model (EAM) proposes that the effects of chronic stress on depression are moderated by unhealthy behaviors and race/ethnicity. The unique social structures and contexts of Hispanics/Latinos in the U.S. may influence such relationships. This study evaluated whether unhealthy behaviors weakened the relationship between allostatic load, a measure of chronic stress, and future elevated depressive symptoms among Hispanic Community Health Study/Study of Latinos participants.MethodsLongitudinal data (2008–2011 and 2014–2017) from 11,623 participants were analyzed. The exposure was allostatic load, an index of twelve established biomarkers categorized using clinically relevant cut points, at Visit 1. Elevated depressive symptoms were operationalized as a score of ≥10 (out of 30) on the CES-D 10 at Visit 2. An index of unhealthy behaviors, with one point each for cigarette smoking, excessive/binge drinking, sedentary behavior, and poor diet quality at Visit 1, was examined as an effect modifier. Multivariable logistic regression, in the overall sample and among Mexicans specifically and adjusted for demographic characteristics and elevated depressive symptoms at Visit 1, was used to model allostatic load, unhealthy behavior index (range: 0–4), and their interaction in relation to elevated depressive symptoms at Visit 2.ResultsOverall, greater allostatic load was associated with higher odds of elevated depressive symptoms after at least 6 years (aOR = 1.06, 95% CI = 1.01, 1.10). Overall, individuals with greater allostatic load and an unhealthy behavior index = 1, compared to those with an unhealthy behavior index = 0, had lower odds of elevated depressive symptoms at follow-up (aβ = −0.065, 95% CI = −0.12, −0.007).ConclusionsThe relationship between chronic stress and depression was partially moderated among Hispanics/Latinos who engaged in unhealthy behavior, which may have reduced their risk of elevated depressive symptoms given more chronic stress.

Depressive Symptoms and Associated Health-Related Variables in Older Adult Breast Cancer Survivors and Non-Cancer Controls.

To examine the prevalence of depressive symptoms and associated risk factors in older adult breast cancer survivors (BCS) and age-matched non-cancer controls. Using the Surveillance, Epidemiology, and End Results-Medicare Health Outcome Survey linked dataset from 1998 to 2012, BCS and non-cancer controls aged 65 years or older were identified. Depressive symptoms, comorbidities, functional limitations, socio-demographics, and health-related information were examined. Univariate and multivariable logistic regression and marginal models were performed. 5,421 BCS and 21,684 controls were identified. BCS and non-cancer controls had similar prevalence of depressive symptoms. Having two or more comorbidities and functional limitations were strongly associated with elevated risk of depressive symptoms in BCS and non-cancer controls. Having multiple comorbidities and multiple functional status are key factors associated with depressive symptoms in older adult BCS and non-cancer controls. Nurses are in an ideal position to screen older adult BCS and non-cancer controls at risk for depressive symptoms.

Sleep Disordered Breathing Measures in Early Pregnancy Are Associated with Depressive Symptoms in Late Pregnancy.

Sleep disordered breathing (SDB) and depression are both common complications of pregnancy and increase risk for adverse maternal and neonatal outcomes. SDB precedes onset of depression in non-pregnant adults; however, the longitudinal relationship has not been studied in pregnancy. The present research examined temporal associations between SDB and depressive symptoms in 175 pregnant women at risk for SDB (based on frequent snoring and obesity), but without an apnea hypopnea index of ≥5 events per hour at enrollment. Women completed a self-report assessments of depressive symptoms using PHQ-9 and in-home level III sleep apnea monitoring at approximately 12- and 32-weeks’ gestation. We also assessed the risk for SDB using the Berlin Questionnaire in early pregnancy. Results revealed that measures of SDB in early pregnancy as assessed by in-home sleep study, but not by self-reported SDB, predicted elevated depressive symptoms in late pregnancy. SDB in late pregnancy was not associated with depressive symptoms. To conclude, these findings suggest that SDB may increase the risk for elevated depressive symptoms as pregnancy progresses.

Psychological experiences of healthcare professionals in Sri Lanka during COVID-19

BackgroundThe upsurge of COVID-19 has caused numerous psycho-social challenges for healthcare professionals because of its ability to spread rapidly in the community and high mortality rate. The seriousness of the disease has led many healthcare professionals plagued by stigma as well as discrimination. In this study, depressive symptomatology, levels of anxiety, and related psychosocial and occupational factors experienced by healthcare professionals in Sri Lanka during COVID -19 were investigated.MethodsA total of 512 healthcare professionals were surveyed using an online survey. The Generalized Anxiety Disorder 7-item scale, the Center for Epidemiologic Studies Depression Scale-Revised-10, and psychosocial and occupational factors predictive of depression and anxiety were included in the survey questionnaire. Logistic regression determined the factors associated with the presence of depressive symptoms and anxiety.ResultsResults showed that elevated depressive symptoms and anxiety were experienced by 53.3% and 51.3%, respectively, of the participants. No differences in the prevalence of elevated depressive symptoms and anxiety were found between those who were exposed and non-exposed to COVID-19 confirmed or suspected patients. Having a fear of being infected with COVID-19 and spreading it among family members were associated with increased risk of depression. Among those exposed to COVID-19 confirmed or suspected patients, poor occupational safety (OR = 2.06, 95% CI 1.25–3.39), stigmatization (OR = 2.19, 95% CI 1.29–3.72), and heavy workload (OR = 2.45, 95% CI 1.53–3.92) were associated with increased risk of elevated depressive symptoms, whilst poor self-confidence (OR = 2.53, 95% CI 1.56–4.09) and heavy workload (OR = 1.94. 95% CI 1.22–3.12) were associated with increased risk of anxiety.ConclusionsFear of being infected and distress caused by fear of spreading it among family members, stigmatization, poor self-confidence, poor occupational safety and heavy workload are vital risk factors that need to be considered in future psychological support services designed for the healthcare professionals in unprecedented outbreaks like COVID-19.

Does Participation in Food Benefit Programs Reduce the Risk for Depressive Symptoms?

Food insecurity affects 15 million households in the United States and is associated with negative physical and mental health outcomes including Major Depressive Disorder. Governmental public assistance or food benefit programs including the Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children (WIC) are social intervention services that attempt to minimize food insecurity for low-income households. There is little consensus regarding the effects of food benefit participation on reducing risk of depressive symptoms. This study aims to explore the association between household food insecurity and food benefit participation (SNAP or WIC) on risk for depressive symptoms using nationally representative samples from the Center for Disease and Control and Prevention Nutritional Health and Nutrition Examination Survey 2013-2014 and 2015-2016 cohorts. We hypothesize that food insecurity is associated with increased risk of depressive symptoms and food benefit participation with reduced risk. Cross-sectional analyses were conducted using survey-weighted logistic regression to explore the relationship between food insecurity, food benefit participation, and the risk of depressive symptoms controlling for relevant income and sociodemographic variables. When controlling for sociodemographic variables, food benefit participation did not reduce the risk of depressive symptoms, while high levels of food insecurity were associated with elevated risk. High levels of food insecurity are associated with elevated risk of depressive symptoms. Nurses and public health professionals can address food security needs through increased knowledge of referral and eligibility requirements. Implications on clinical practice, policy, and future directions for research are discussed.

Lipoprotein (a) and the risk of elevated depressive symptoms: The Multi-Ethnic Study of Atherosclerosis

Previous studies suggested a potential relationship between plasma lipoprotein (a) [Lp(a)] and elevated depressive symptoms. We aimed to investigate any such relationship in the Multi-Ethnic Study of Atherosclerosis participants who were free of cardiovascular events. Analysis included 4938 participants without elevated depressive symptoms and with Lp(a) levels measured at baseline. Participants were examined at four clinic visits over a 10-year period. Elevated depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale (CES-D) and were defined as a CES-D score ≥16 or use of anti-depressants. Lp(a) level was measured with a latex-enhanced turbidimetric immunoassay. After adjusting for demographics, socioeconomic factors and other confounding factors in Cox regression analyses, a higher ln-transformed Lp(a) level was associated with new elevated depressive symptoms since baseline (hazard ratio [95% CI] = 1.09 [1.02–1.16] per SD increment in ln-transformed level, P = 0.01). However, no association was found when elevated Lp(a) levels were assessed using clinical cut-off point (≥30 or 50 mg/dL), nor in sensitivity analyses using alternative definitions of elevated depressive symptoms. No significant interaction with race/ethnicity was found for all the above analyses. Also, no significant association was found between baseline Lp(a) levels and absolute or relative changes in CES-D score between baseline and last follow-up visits. Our study suggests a potential association between Lp(a) level and new elevated depressive symptoms, but such association was not robust in the sensitivity analyses. Future studies are warranted to investigate the role of Lp(a) in depressive symptoms in other cohorts.
