Traumatic life events as predictors for depression in middle-aged men and women: A Finnish twin study

BackgroundWe examined exposure to adulthood traumatic life events (TLEs) and their associations with depression in women and men. Then we examined whether those associations are independent of exposure loading and vulnerability including familial confounding. MethodsThe fourth survey in 2011 of the population-based Finnish Twin Cohort had 8410 participants (45 % men, mean age 60 years). Using the Center for Epidemiologic Studies Depression (CES-D) scale, depression was defined using a cut-off value ≥20. Participants reported exposure to TLEs during adulthood. Logistic regression adjusted for multiple covariates was used as the individual-based analyses. Familial confounding was tested using conditional logistic regression in 399 twin pairs discordant for depression. ResultsMore women (15 %) than men (11 %) were depressed. Men reported more traffic accidents (men: 11.8 %, women: 7.4 %), other serious accidents (11.8 %, 5.8 %), and violent crime (3.1 %, 2.0 %) whereas women reported more sexual assault (0.7 %, 10.6 %). Violent crime (Odds Ratio 3.86; 95 % Confidence Intervals 2.59, 5.73), sexual assault (3.49; 2.67, 4.55), physical assault (3.10; 2.45, 3.93), and other serious accidents (1.36; 1.01, 1.85) were associated with depression. These associations, except other serious accidents, remained significant after adjusting for multiple covariates including shared familial factors. The associations did not differ by sex. LimitationsA relatively small set of relevant TLEs was reported retrospectively and the order of TLEs was not assessed. ConclusionsWomen and men differ in exposure to TLEs but, if exposed, they are equally vulnerable for depression. Because traumatic life events are robustly associated with depression, they should be considered in treatment.

The relationship between asthma and suggested alcohol dependence and heavy alcohol use in the Cooper Center longitudinal study: The role of depressive symptom severity

BackgroundAsthma appears to be associated with a variety of psychiatric illnesses including depression and alcohol use disorder. The current study examined the relationship between asthma, heavy alcohol intake and suggested alcohol dependence controlling for depressive symptom severity. MethodsData from 33,253 adult patients at the Cooper Clinic who enrolled in the Cooper Center Longitudinal Study, completed a medical history questionnaire including information on asthma, depressive symptoms and alcohol use were used. The association between lifetime asthma and heavy alcohol intake, while accounting for depressive symptoms (10-item Center for Epidemiological Studies-Depression (CESD)), and demographic variables was examined employing logistic regression with heavy alcohol intake (yes/no) as the outcome. Logistic regression was similarly utilized to examine the association between asthma and suggested alcohol dependence (CAGE scores ≥2: yes/no) among current drinkers (n = 26,028). ResultsMultivariable analysis revealed no significant association between asthma and heavy alcohol consumption with or without controlling for CES-D scores. Asthma was, however, associated with higher odds for suggested alcohol dependence (OR 1.18, CI 1.07, 1.31), which was attenuated but still significant when controlling for CES-D scores. ConclusionAsthma was associated with higher risk for suggested alcohol dependence while current heaving drinking risk was not increased. The suggested drinking findings were slightly less strong when controlling for CES-D scores. The differences between current heavy drinking and CAGE findings might be due to differences in perception of problematic drinking by people with asthma or the timeframe of the assessments (current for drinking, lifetime for CAGE).

Sex-Specific Association of Low Muscle Mass with Depression Status in Asymptomatic Adults: A Population-Based Study

Background: The objective of this study was to examine the correlation between low muscle mass (LMM) and depression, with a specific focus on identifying the sex-specific relationship between LMM and depression in a large sample. Methods: This population-based cross-sectional study involved 292,922 community-dwelling adults from 2012 to 2019. Measurements were taken using the Center for Epidemiological Studies Depression (CESD) scale and body composition analyses. Depression was defined as a CESD score ≥ 16, and severe depression as a CESD score ≥ 22. LMM was defined as an appendicular muscle mass/height2 below 7.0 kg/m2 in men and below 5.4 kg/m2 in women. Sex-based multivariable logistic regression analyzed the LMM–depression association, adjusting for confounders, with depression status and severe depression status as dependent variables. Results: Both men and women in the LMM group had an increased odds of depression (men, adjusted odds ratio = 1.13 [95% confidence interval = 1.03–1.12]; women, 1.07 [1.03–1.23]) and severe depression (men, 1.20 [1.05–1.36]; women, 1.10 [1.04–1.15]) compared to those in the control group. Men showed a stronger association between LMM and the presence of depression (p for interaction = 0.025) and the presence of severe depression (p for interaction = 0.025) compared to women. Conclusions: Decreased muscle mass was independently associated with increased chances of depression and severe depression in both sexes, with a significantly stronger association in men compared to women. This highlights the potential significance of LMM as a predictor of depression, particularly in men.

A mindfulness-based intervention for Substance Use Disorder in a Brazilian vulnerable population: a feasibility mixed method study.

Substance Use Disorder (SUD) is a chronic condition that impacts various facets of an individual's life, and society as a whole. The Mindfulness-Based Relapse Prevention (MBRP) protocol is an innovative intervention that can help to prevent relapse, particularly when used as a post-treatment approach. However, although there is significant evidence of its effectiveness in studies from high-income countries (HICs), there is a dearth of studies examining its feasibility and efficacy in low- and middle-income countries (LMICs). Thus, this study investigates the feasibility of MBRP as an adjunct to outpatient treatment for SUD in a socially vulnerable Brazilian population. The study employed a mixed-methods design in eight Psychosocial Care Centers for Alcohol and Drugs (CAPS-ad) in the city of São Paulo, and involved 140 participants, 24 healthcare professionals and 7 CAPS-ad managers. In total, 17 MBRP intervention groups were conducted. The study assessed qualitative indicators of acceptability, demand, implementation, adaptation, integration, and limited efficacy testing through group interviews, in-depth interviews and field diary records. It also included limited efficacy testing of the protocol using a quantitative pre-post pilot study to investigate consumption behavior, using the Timeline Followback (TLFB) assessment method; depression, using the Center for Epidemiologic Studies Depression (CES-D) scale; anxiety, using the state trait anxiety index (STAXI-2); craving, using the Penn Alcohol Craving Scale (PACS); readiness to change, using the Readiness-to-Change Ruler (RCR); and severity of dependence, using the Severity of Dependence Scale (SDS). The qualitative data were triangulated with the quantitative data to comprehensively evaluate the feasibility of the intervention. The sample comprised socially vulnerable participants with a high dropout rate, primarily due to social factors. Despite facing challenges in respect of regular engagement and initial cultural misperceptions of meditation, the intervention showed positive acceptance and mental health benefits, including impacts on consumption behavior. The study emphasizes the importance of adapting the format of the protocol to better suit vulnerable populations, and to ensure its effective integration into the public healthcare system. Future research should explore protocol modifications, assess its effectiveness in different contexts, and conduct cost-benefit analyses for broader implementation.

The effect of depression on the outcome of infertile females underwent the first In Vitro Fertilization procedure

Background: Infertility affects married adults, and In Vitro Fertilization (IVF) is an Assisted Reproductive Technology (ART) that can treat it. Women undergoing IVF are more likely to experience depression. There is a need to reduce depression by supporting and advising sufferers. The aim of this study is to evaluate the effect of depression on pregnancy rates among infertile females underwent IVF treatment. Materials and Methods: This observational study analyzed 149 patients attending the infertility center at Kamal Al-Samaraie hospital seeking a chance of a conception. The participants received a traditional hospital protocol. The study assessed depression status using the CES-D (Center for Epidemiologic Studies Depression) scale at the beginning of the IVF cycle. Results: Conclusion: Our findings show that the pregnancy rate was not related to baseline depression of women underwent the first IVF procedure. .

Depression and its risk factors in a conflict-affected population: findings from a nationwide survey

Abstract Introduction The impact of armed conflict and war on mental health is well documented, with limited data on populations living in unrecognized states. In this study, we examined the prevalence and risk factors of symptoms of depression among the Nagorno-Karabakh population during a ceasefire period, prior to a blockade, full-scale military attack, and their forced displacement. Methods A total of 1023 women, aged 18-49 years, from all regions of Nagorno-Karabakh, participated in a population-based household survey in 2022, which included the Center for Epidemiologic Studies-Depression (CES-D) 16-item scale to assess their depression symptoms. Simple and multivariable linear regression analyses explored the socio-demographic factors associated with CES-D score. Results The mean CES-D score was 8.90 (SD = 8.93), and 13.1% of the respondents had a score >18 (presence of depressive symptoms). The adjusted linear regression showed that CES-D score was higher among divorced (2.66, SE = 1.15, p-value=0.021) or widowed (3.09, SE = 1.57, p-value=0.049) vs. married, and among those having war-related deaths in the household in the previous 2 years (8.60, SE = 1.65, p-value<0.001) vs. not having. Conversely, a vocational/university level (-2.33, SE = 0.70, p-value=0.001) or post-graduate education (-3.81, SE = 1.72, p-value=0.027) vs less than secondary/secondary level, and 3-5 members in the household (-2.71, SE = 1.16, p-value=0.020) vs.1-2 members were significantly associated with lower CES-D score. Conclusions Our findings suggest that depression symptoms are highly prevalent among women in conflict-affected areas, with specific socio-demographic factors increasing the risk of depression symptoms. These results highlight the importance of providing mental health support and interventions for women in conflict-affected areas, particularly for those who experienced loss in the family due to war, are divorced or widowed, live in small households, and have lower education. Key messages • Depression symptoms are highly prevalent among women of reproductive age in areas affected by armed conflict and war. • Mental health intervention is recommended for women in conflict-affected areas who experienced loss due to war, are divorced or widowed, live in small households and/or have lower education.

Longitudinal association of homocysteine with depressive and anxiety symptoms among urban adults: healthy aging in neighborhoods of diversity across the life span study.

Longitudinal associations of homocysteine (HCY) with depressive symptoms scores among urban adults remain under-studied, especially across sex, race and levels of anxiety. We examined longitudinal associations of homocysteine (HCY) with depressive symptoms scores among urban adults, before and after stratifying by sex, race and anxiety level, using data from 1460 Healthy Aging in Neighborhoods of Diversity across the Lifespan Study (HANDLS) participants aged 30-64 y at v1 (2004-2009), followed across 3 visits up to 2017. In addition to LnHcyv1, we used group-based trajectory models predicting z-transformed likelihood of greater LnHcy with age (Hcytraj). Total and domain-specific depression symptoms were scored using Center for Epidemiologic Studies Depression (CES-D) scale. Mixed-effects linear regression models and Cox proportional hazards models were utilized. A positive association was found between baseline LnHcyv1 and CES-D total scores in reduced socio-demographic- adjusted Model 1 (β (standard error [SE]) = + 2.337 (0.902), P = 0.010), a relationship slightly attenuated in fully adjusted Model 2 (Model 1 adjusting for lifestyle and health factors) with a β (SE) = + 1.825 (0.883), P = 0.039. Individuals with lower anxiety levels experienced faster CES-D domain 2 score annualized increase over time (interpersonal problems) with higher LnHcyv1 (β (SE) = 0.041 (0.018), P = 0.024). Hcytraj was linked to incident elevated depressive symptoms (CES-D total score ≥16) overall (fully adjusted model: HR = 1.09, 95% CI: 1.03-1.14, P = 0.001), particularly among women and those living in poverty. Baseline and "high trajectory" of LnHcy were positively associated with depressive symptoms and elevated depressive symptom incidence, in a sex-, race-, poverty status- and anxiety-level specific manner.

Association between husband's participation in household work and the onset of depressive symptoms in married women: A population-based longitudinal study in South Korea

An unequal distribution of household work by gender is prevalent. This study explored the association between husbands' participation in household work and the onset of depressive symptoms among married Korean women. A nationwide sample of 7024 married women was repeatedly followed up at 2-year intervals from 2014 to 2022 (20,343 observations). The daily household work hours of both the participants and their husbands were self-reported. Satisfaction with husbands' participation in household work was classified as satisfactory, neutral, or dissatisfactory. Depressive symptoms were assessed using the 10-item version of the Center for Epidemiologic Studies Depression. A generalized estimating equation was employed to determine how household work participation was associated with the onset of depressive symptoms in married women at the 2-year follow-up. The risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. The mean daily hours spent on household work were 2.62 h for married women and 0.35 h for husbands. A 1-h increase in the husbands' daily time spent on household work was negatively associated with the risk of onset of depressive symptoms in married women (RR: 0.88, 95% CI: 0.80–0.98). Compared with individuals with neutral responses, those satisfied with their husband's household work had a lower risk of depressive symptom onset (RR: 0.82, 95% CI: 0.74–0.90), whereas dissatisfaction was linked to increased risk (RR: 1.15, 95% CI: 1.04–1.27). Husbands' participation in household work was associated with a reduced risk of depressive symptom onset among married women. Achieving gender equality in the division of household work is important for women's mental health.

Are depressive symptoms associated with biological aging in a cross-sectional analysis of adults over age 50 in the United States.

Major depressive disorder accelerates DNA methylation age, a biological aging marker. Subclinical depressive symptoms are common, but their link to DNA methylation aging in older adults remains unexplored. This study analyzed the cross-sectional relationship between depressive symptoms and accelerated DNA methylation aging, considering gender and race/ethnicity in U.S. adults aged over 50. We used data from 3,882 diverse participants in the 2016 Health and Retirement Study wave, measuring blood DNA methylation age against chronologic age for acceleration. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. Multiple linear regression evaluated the association between depressive symptoms and DNA methylation age acceleration, adjusting for sociodemographic factors, blood cell proportions, and health behaviors (physical activity, alcohol use, smoking, and chronic conditions). Gender and race/ethnicity modifications were also tested. Depressive symptoms, measured by continuous CES-D score, high depressive symptoms (CES-D ≥ 4), or any symptoms (CES-D ≥ 1), significantly correlated with increased GrimAge DNA methylation age acceleration (all p ≤ .001) in unadjusted and sociodemographic-adjusted models but were nonsignificant in fully adjusted models. No significant gender or race/ethnicity effect modifications were found in fully adjusted models. Health behaviors significantly influence DNA methylation age acceleration and depressive phenotypes, underscoring the need to understand their roles in assessing psychological factors related to DNA methylation age acceleration.

Prevalence and Associated Factors of Depressive Symptoms among Older Adults in the Philippines.

Depressive symptoms may increase with age, potentially influenced by sociodemographic characteristics, stressors and support, health status, and health behaviour. It is unclear if this is the case among older adults in the Philippines. Therefore, the aim of this study is to estimate the prevalence and associated factors of depressive symptoms among older adults in the Philippines. In all, 5209 items of cross-sectional nationally representative data from older adults (≥60 years) participating in the 2018 Longitudinal Study on Ageing and Health in the Philippines (LSAHP) were analysed. Depressive symptoms were assessed using the 11-item 3-response category Center for Epidemiological Studies Depression (CES-D) Scale. The overall prevalence of depressive symptoms was 32.1%, with 25.6% among older men and 36.5% among older women. In the final adjusted models, overall, widowed (Adjusted Odds Ratio (AOR): 1.52, 95% Confidence Interval (CI): 1.00 to 2.30), hunger (AOR: 2.22, 95% CI: 1.40 to 3.51), living alone (AOR: 1.61, 95% CI: 1.00 to 2.59), not satisfied with present life (AOR: 2.04, 95% CI: 1.09 to 3.81), body pain (AOR: 2.39, 95% CI: 1.73 to 3.31), and insomnia (AOR: 1.69, 95% CI: 1.24 to 2.31) were positively associated, while working (AOR: 0.55, 95% CI: 0.37 to 0.80) was negatively associated with depressive symptoms. In addition, among men, older age (80 years and above) (AOR: 1.95, 95% CI: 1.06 to 3.58), unmet healthcare needs (AOR: 2.19, 95% CI: 1.07 to 4.47), and hearing difficulty (AOR: 2.41, 95% CI: 1.06 to 5.52) were positively associated poor childhood health (AOR: 0.12, 95% CI: 0.04 to 0.36), while social network (AOR: 0.94, 95% CI: 0.90 to 0.99) was negatively associated. Among women, loss of bladder control (AOR: 1.69, 95% CI: 1.03 to 2.77) was positively associated with depressive symptoms. One in three older adults participating in this study exhibited depressive symptoms. Sociodemographic factors, stressors, and health status factors were positively associated, and support factors were negatively associated with depressive symptoms.

Associations of caring for grandchildren and great-grandparents with depressive symptoms and life satisfaction in Chinese grandparents: The moderating roles of urban-rural residence and social participation.

This study aims to investigate the associations of caring for grandchildren and/or great-grandparents with depressive symptoms, as well as life satisfaction in Chinese grandparents, and analyze the moderating roles of urban-rural residence and social participation. A nationally representative sample of 2973 grandparents in families with great-grandparents and grandchildren were selected from the 2018 China Health and Retirement Longitudinal Study (CHARLS). The Center for Epidemiologic Studies Depression (CESD-10) and the single-item were used to measure depressive symptoms and life satisfaction. Social participation included participation in social and intellectual activities. The binary logistic regression model was employed to explore the relationship between caring and depressive symptoms, as well as life satisfaction in the whole participants, different urban-rural residence, and social participation groups, respectively. Caring was associated with depressive symptoms and life satisfaction (p < 0.05). A significant interaction existed between caring and urban-rural residence for depressive symptoms (interaction p = 0.029) and life satisfaction (interaction p = 0.027). Significant interactions were also found among caring, urban-rural residence, and social activities with depressive symptoms (interaction p = 0.025). In urban, caring for both was negatively related to depressive symptoms for the non-social activists, while in rural, caring for great-grandparents was positively associated with depressive symptoms for social activists (p < 0.05). Any new policy design related to preventing and reducing the possibility of mental disorders in Chinese grandparents should be tailored to heterogeneous subgroups who live in different rural-urban and social activities participation.

The Effects of Music Therapy on Self-Management, Depression, and Stress in Patients with Type 2 Diabetes Mellitus

Background: Among type 2 diabetes patients hospitalized for blood sugar control, stress and depression are high and have a negative effect on blood sugar control. Therefore, this study sought to determine whether listening to music helps reduce stress and depression and affects blood sugar control.Methods: This is a randomized, controlled, pre- and post-design study conducted from April 2017 to September 2019 in patients with type 2 diabetes hospitalized for blood glucose control at Kyung Hee University Hospital at Gangdong. After diabetes education was provided to both the control and experimental groups, the experimental group listened to music for 30 minutes a day with a tablet PC and the control group was prohibited from listening to music during the study period. Stress was evaluated using the PAID (Problem Areas in Diabetes) scores, depression using the CES-D (Center for Epidemiologic Studies Depression) scale, and self-management using the SDSCA (Summary of Diabetes Self-Care Activities) questionnaire.Results: A total of 59 patients (41.5 ± 12.6 years, 75.0% male) were enrolled and randomized into the control group (n = 28) and experimental group (n = 31). Music therapy had no statistically significant relationship with blood sugar (&lt;i&gt;P&lt;/i&gt; = 0.887), depression (&lt;i&gt;P&lt;/i&gt; = 0.248), stress (&lt;i&gt;P&lt;/i&gt; = 0.994), or self-management (&lt;i&gt;P&lt;/i&gt; = 0.959). However, in both groups, blood glucose control, stress, and self-management were all significantly improved at discharge compared to at the beginning of hospitalization (&lt;i&gt;P&lt;/i&gt; = 0.031).Conclusion: It was confirmed that intensive medical treatment and diabetes education for hospitalized patients with type 2 diabetes improved not only blood glucose control but also depression, stress, and self-management, regardless of listening to music.

Timed instrumental activities of daily living tasks in adults with irreversible vision impairment: validation to visual function and self-report

BackgroundInstrumental activities of daily living (IADL) are typically self-reported ability to perform complex tasks vital for independent living. There is a need for a complementary objective, performance-based approach especially in tracking outcomes in visual rehabilitation for patients with irreversible vision impairment (“low vision”). Our goals are: (1) To describe the validity of timed performance of instrumental activities of daily living (timed IADL or TIADL) tasks in individuals with irreversible vision impairment, by examining its association with visual function (visual acuity, contrast sensitivity, visual field), (2) To explore the correlation between TIADL and self-reported IADL.MethodsTwenty TIADL tasks were administered to 88 patients (median age 63.3 years, IQR 37.4–78.0) recruited from the UAB Department of Ophthalmology, Callahan Eye Hospital Clinics. An average Z-score incorporating time and accuracy of task completion was constructed. Minor accuracy errors were penalized 1 standard deviation from their calculated Z-score and major accuracy errors were assigned maximum allotted time. Linear regression was used to analyze the association between TIADL score and measured visual acuity (Early Treatment Diabetic Retinopathy Study, ETDRS chart), contrast sensitivity (Pelli-Robson), and binocular visual field (Esterman) with an unadjusted model and an adjusted model accounting for age, comorbidities, and depression scale (Center for Epidemiological Studies Depression, CES-D). Pearson correlation was used to estimate the correlation between TIADL and IADL.ResultsIncreased time to task completion was associated with decreased visual function. Each decreased line of ETDRS read was associated with an increase of 0.002 (95% CI 0.001, 0.002) Z-score (P < 0.01). A decreased ability to discern each Pelli-Robson letter was associated with an increase of 0.26 (95% CI 0.19, 0.33) Z-score (P < 0.01). For each less Esterman target identified, there was an increase of 0.01 (95% CI 0.003, 0.02) Z-score. Self-reported IADL and TIADL were correlated for reading tasks such as newspapers, nutrients on food can, and microwave timer (P < 0.05).ConclusionsLonger time to perform TIADL is associated with decreased visual acuity, contrast sensitivity, and binocular visual field. TIADL and self-reported IADL are significantly correlated for reading tasks providing an accurate, complementary outcome measure in clinical practice and research.

Comprehensive needs assessment tool for informal cancer caregivers (CNAT-ICs): Instrument development and cross-sectional validation study

BackgroundGrowing cancer incidence and its subsequent burden is a worldwide concern. Needs assessment for caregivers has recently received growing attention, as it identifies specific unmet needs. The remaining tools have been established within the healthcare context of Western countries and have been studied only in some Asian populations; it seems appropriate to develop needs assessment tools that apply to a wider ethnic and socio-cultural context. ObjectiveThis study planned to adapt and examine the psychometric properties of the CNAT-C for the Sri Lankan informal caregivers for wider applicability. DesignAn instrument development and cross-sectional validation study was conducted. SettingApeksha Hospital Maharagama, Sri Lanka (National Cancer Institute). ParticipantsA sample of 226 informal caregivers (ICs) providing palliative care for patients with advanced cancer was selected. MethodsA CNAT-C (41 items; seven factors) was incorporated and used after a cross-cultural adaptation following WHO guidelines after the permission and pilot test. ICs completed the socio-demographic and clinical details along with the validated Centre for Epidemiological Studies-Depression (CES-D), and the World Health Organization-Quality of Life-Brief (WHOQOL-BREF). Internal consistency and test-retest were used to check the reliability. Convergent and divergent validity of the Sinhala version of CNAT (S-CNAT) was confirmed using the CES-D scale and WHOQOL-BREF. Construct validity was evaluated using the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). ResultsMost of the participants were female (60 %) and married (72 %), and the mean age was 41.78 (SD+14.54). Face and content validity were established during the cross-cultural adaptation. Cronbach's alpha was 0.903 for the overall S-CNAT and the test-retest reliability was 0.965. The S-CNAT was associated positively with the CES-D while negatively with the WHOQOL-BREF. Both EFA and CFA discovered a structure contained seven factors (35 items); domain named as healthcare staff/nurses’ support and information, physical/practical needs, medical officers’ support, psychological needs, social/family support, spiritual/religious support, and hospital facilities/service. ConclusionsThe Sinhala version of CNAT is shown to have adequate validity and reliability in assessing the comprehensive and multidimensional/unmet needs of informal caregivers of patients with advanced cancer (S-CNAT-ICs). It would be a helpful tool to determine the unmet needs of ICs and guide future interventions to meet those needs and enhance or maintain the quality of life for patients and their informal caregivers.

Neighborhood Safety Concerns and the Onset of Depressive Symptoms Among Women: A Population-based Prospective Cohort Study in South Korea.

Neighborhood safety is crucial for the well-being of residents; however, longitudinal evidence is scarce. This study explored the association between neighborhood safety concerns and depressive symptoms among women. A nationally representative sample of 10,008 women was surveyed in 2016. Six dimensions of neighborhood safety concerns were assessed: crime, food, safety at night, traffic accidents, building and facility, and general safety. The total score for neighborhood safety concerns ranged from 6 to 24, with higher scores indicating greater concerns. Depressive symptoms were assessed using the 10-item version of the Center for Epidemiologic Studies Depression. For cross-sectional analyses, we explored how neighborhood safety concerns were associated with concurrent depressive symptoms at baseline. For the longitudinal analyses, we explored how they were associated with depressive symptom onset at the 2-year follow-up (2018) among women without depressive symptoms at baseline (n = 7,643). Logistic regressions were employed. The mean (standard deviation [SD]) of the neighborhood safety concern score was 12.7 (3.3). In the cross-sectional analysis, a 1-SD increase in neighborhood safety concern score was associated with 1.23-fold (95% CI: 1.13-1.35) increase in the odds of concurrent depressive symptoms at the baseline year. In the longitudinal analysis, a 1-SD increase in neighborhood safety concern score was associated with 1.15-fold (95% CI: 1.03-1.29) increase in the odds of experiencing the onset of depressive symptoms at the follow-up year. This study suggests that neighborhood safety concerns are risk factors for the development of depressive symptoms of female residents. Policy efforts are necessary to ensure community safety.

B - 44 Examining Test–Retest Reliability and Mean Score Differences in Self-Reported Neuropsychological Symptoms in Active-Duty and Veterans with Mild Traumatic Brain Injury (Mtbi)

Abstract Objective Test–retest reliability is a foundational psychometric property of tests, providing a means through which tests may be assessed for time invariant interpretation. This study evaluated the test–retest reliability of several self-report instruments commonly employed in a veteran/military neurocognitive rehabilitation setting. Method Repeat administration of the Neurobehavioral Symptom Inventory (NSI), Key Behaviors Change Inventory (KBCI), Veterans RAND 12 Item Health Survey (VR12), C4 Inventory, Center for Epidemiologic Studies-Depression, Post-traumatic Checklist-DSM-5 (PCL-5), and the Epworth Sleepiness Scale (ESS) was collected across baseline, one, four, and twelve week timepoints. Interclass correlation coefficients and a two-way mixed ANOVA was conducted on 31 Veteran and 22 Active-duty participants (71.5% male). Results Most measures demonstrated a significant mean difference during follow-up, with reductions across the 1- and 4-week follow-ups. ICC ranged from good to excellent (0.76–0.93) across the measures. Correlations between time points on measures were high (e.g., PCL-5 Baseline/4wk r = 0.93), suggesting high reliability for measures despite changing scores after treatment completion. Conclusions This study found good test–retest reliability across the three follow-up timelines, supporting the use of the included measures in neurocognitive rehabilitation settings. Reliability and post-treatment changes in symptoms observed across these measures will be further discussed.

Symptoms and Diabetes among Chinese Middle-Aged and Elderly Adults with Prediabetes: A National Cohort Study.

We aimed to assess the association between depressive symptoms and the risk of transition from prediabetes to diabetes. We included 3,956 adults with prediabetes aged 45 years and above in 2011. Participants with a ten-item Center for Epidemiologic Studies Depression (CES-D) score of 10 or higher were classified as having depressive symptoms. Incident diabetes was defined as a self-reported physician diagnosis of diabetes, or treatment with glucose-lowering medication in 2013, 2015, or 2018. Among 3, 956 participants (mean age was 59.53 years old and 53.29% were female), the proportion of depressive symptoms was 36.50% in 2011. During the 24,831 person-years of follow-up, 458 participants developed diabetes and the incidence rate was 18.44 (95% CI 16.83 to 20.21) per 1000 person-years. Depressive symptoms were significantly associated with a higher risk of incident diabetes (HR, 1.31; 95% CI, 1.07 to 1.59). In addition, the association was in a dose-response fashion (P trend < 0.001). Compared with the CES-D <10 group, the HRs (95% CI) were 1.21 (0.98 to 1.49) in the 10≤ CES-D <21 group, and 1.95 (1.38 to 2.75) in the CES-D ≥ 21 group. Depressive symptoms were shown as an independent risk factor for the progression from prediabetes to diabetes.

African American Family Caregivers' Experiences and Mental Health: A Convergent Mixed-Methods Study.

Caregiving in the African American community is informed by strong cultural expectations but may be associated with negative experiences and poor mental health outcomes. The purpose of this convergent mixed-methods study is to understand the relationship between caregiving experiences and mental health and explore stress management strategies in African American family caregivers of adults with chronic or disabling conditions. African American family caregivers (N = 100) were recruited using community-engaged methods and completed a sociodemographic questionnaire, the Caregiver Reaction Assessment scale, and the Center for Epidemiologic Studies Depression (CES-D-10) Scale. A subsample (n = 24) participated in semi-structured interviews. Data were analyzed using linear regression and content analysis. A matrix was developed to integrate quantitative and qualitative results. Participants were on average 59 years old. Most were women and provided care to a parent. Lack of family support (B = 1.37, P = .03) and impact of caregiving on caregivers' finances (B = 1.74, P = .004), schedule (B = 2.92, P < .001), and health (B = 3.26, P < .001) were associated with depressive symptoms and were reported as stressful experiences. Negative interactions with the care recipient and caring for multiple people emerged as other sources of stress. Participants used independent and interpersonal coping strategies, as well as strategies to facilitate their caregiving role to reduce their stress. Values of reciprocity, limited use of community-based resources, and mental health stigma emerged as important cultural considerations. Our findings suggest the need for culturally-sensitive interventions to improve communication and care coordination within African American family caregiving networks and educational programs about mental health and caregiving resources endorsed by trusted community sources.

Prenatal exposure to ambient air pollution and persistent postpartum depression

BackgroundAmbient air pollution during pregnancy has been linked with postpartum depression up to 12 months, but few studies have investigated its impact on persistent depression beyond 12 months postpartum. This study aimed to evaluate prenatal ambient air pollution exposure and the risk of persistent depression over 3 years after childbirth and to identify windows of susceptibility. MethodsThis study included 361 predominantly low-income Hispanic/Latina participants with full-term pregnancies in the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) cohort. We estimated daily residential PM2.5, PM10, NO2, and O3 concentrations throughout 37 gestational weeks using inverse-distance squared spatial interpolation from monitoring data and calculated weekly averaged levels. Depression was assessed by the 20-item Center for Epidemiologic Studies-Depression (CES-D) scale at 12, 24, and 36 months postpartum, with persistent postpartum depression defined as a CES-D score ≥16 at any of these timepoints. We performed robust Poisson log-linear distributed lag models (DLM) via generalized estimating equations (GEE) to estimate the adjusted risk ratio (RR). ResultsDepression was observed in 17.8 %, 17.5 %, and 13.4 % of participants at 12, 24, and 36 months, respectively. We found one IQR increase (3.9 ppb) in prenatal exposure to NO2 during the identified sensitive window of gestational weeks 13–29 was associated with a cumulative risk ratio of 3.86 (95 % CI: 3.24, 4.59) for persistent depression 1–3 years postpartum. We also found one IQR increase (7.4 μg/m3) in prenatal exposure to PM10 during gestation weeks 12–28 was associated a cumulative risk ratio of 3.88 (95 % CI: 3.04, 4.96) for persistent depression. No clear sensitive windows were identified for PM2.5 or O3. ConclusionsMid-pregnancy PM10 and NO2 exposures were associated with nearly 4-fold increased risks of persistent depression after pregnancy, which has critical implications for prevention of perinatal mental health outcomes.

Depressive symptoms over the final menstrual period: Study of Women's Health Across the Nation (SWAN)

BackgroundWomen may be vulnerable to elevated depressive symptoms during the menopause transition (MT). Studies generally have not considered premenopausal depressive symptom history or examined symptoms in relation to the final menstrual period (FMP). ObjectiveTo identify specific time points in relation to the FMP when depressive symptoms increase or decrease. MethodsParticipants were 1582 multiracial/ethnic women from the longitudinal Study of Women's Health Across the Nation (SWAN). Biological, psychosocial, and depressive symptom data were collected approximately annually. Depressive symptoms were measured by the Center for Epidemiological Studies-Depression (CESD) scale. ResultsWomen with high baseline depressive symptoms (CES-D ≥ 16) declined in symptoms (M = −1.04/yr., 95 % CI = −1.58, −0.50) until 4 years before the FMP, followed by a smaller decrease (M = −0.50/yr., 95 % CI = −0.72, −0.28) until 18 months after the FMP. Depressive symptoms increased (M = 0.21/yr., 95 % CI = 0.11, 0.30) in those with low baseline symptoms until 1 year before the FMP, and decreased (M = −0.06/yr., 95 % CI = −0.11, −0.008) going forward. Greater social support, higher levels of follicle stimulating hormone and estradiol, and less sleep disturbance contributed to greater decline in depressive symptoms among those with high baseline depressive symptoms. Anxiety, experiencing stressful life events, lower body mass index, and poor role-physical function contributed to an increase in depressive symptoms among those with low baseline symptoms. LimitationsExcluded women had higher baseline CES-D scores. Lacked pre-MT depression for pre/early perimenopausal women at baseline. ConclusionAccounting for baseline depressive symptom level and focusing on the FMP more precisely characterize depressive symptom change over the MT.
