The Mediating Role of Perceived Social Support Between Physical Activity Habit Strength and Depressive Symptoms in People Seeking to Decrease Their Cardiovascular Risk: Cross-Sectional Study.

ABSTRACT: BACKGROUND:Regular physical activity treatment has been advocated for the prevention and rehabilitation of patients at risk of cardiovascular diseases and depressive symptoms. How physical activity is related to depressive symptoms is widely discussed. OBJECTIVE:The aim of this internet-based study was to investigate the role of perceived social support in the relationship between physical activity habit strength and depressive symptoms. METHODS:In total, 790 participants (mean 50.9 years, SD 12.2, range 20-84 years) who were interested in reducing their cardiovascular risk were recruited in Germany and the Netherlands. Data collection was conducted via an internet-based questionnaire addressing physical activity habit strength, depressive symptoms, and perceived social support. Cross-sectional data analysis was done with SPSS version 24 using the Macro PROCESS version 2 16.3 by Hayes with bootstrapping (10,000 samples), providing 95% CIs. RESULTS:Physical activity habit strength was negatively related to depressive symptoms (r=-.13, P=.006), but this interrelation disappeared when controlling for perceived social support (beta=-.14, SE 0.09, P=.11). However, there was an indirect relationship between physical activity habit strength and depressive symptoms, which was mediated via perceived social support (beta=-.13; SE 0.04, 95% CI -0.21 to 0.06). The negative relationship between physical activity habit strength and depressive symptoms was fully mediated by perceived social support. CONCLUSIONS:We suggest that physical activity treatment in people interested in reducing their cardiovascular risk should also embed social support to target depressive symptoms. Internet-based interventions and electronic health may provide a good option for doing so.

Project description:BackgroundWhether perceived stress is associated with loneliness and depressive symptoms in general adults, and to what extent sleep quality mediates the associations, remains unknown. The aim of this study was to estimate the associations of perceived stress with loneliness and depressive symptoms, and the mediating role of sleep quality in these associations.MethodsCross-sectional data on 734 participants (aged 18-87 years) were analyzed. Perceived stress was assessed using the 10-item Perceived Stress Scale (PSS-10; range 0-40). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI; range 0-21). Loneliness was assessed using the three-item short form of the Revised University of California, Los Angeles (UCLA) loneliness scale (range 3-9). Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression (CESD-10) Scale (range 0-30). General linear regression models, multivariable logistic regression models, and formal mediation analysis were performed.ResultsAfter adjustment for age and sex, we found that with each 1-point increment in the perceived stress score, both the loneliness score (β = 0.07; 95% confidence interval [CI]: 0.06, 0.08) and depression score (β = 0.45; 95% CI: 0.40, 0.49) increased significantly. Robust results were observed when adjusting for more confounders. Furthermore, sleep quality mediated 5.3% (95% CI: 1.3%, 10.0%; P = 0.014) and 9.7% (95% CI: 6.2%, 14.0%; P < 0.001) of the associations of perceived stress score with loneliness score and depression score, respectively.ConclusionsIn general Chinese adults, perceived stress was positively associated with loneliness and depressive symptoms, and sleep quality partially mediated these associations. The findings reveal a potential pathway from perceived stress to mental health through sleep behaviors, and highlight the importance of implementing sleep intervention programs for promoting mental health among those who feel highly stressed.

Project description:Antenatal depression is associated with adverse maternal and infant well-being. However, compared to postpartum depression, it has been less frequently explored globally or in Jamaica. This study aimed to determine the prevalence of, and factors associated with, antenatal depressive symptoms among Jamaican women in order to inform policy and build interventions that could improve their management and reduce their negative consequences.This secondary analysis of data from the second Jamaican Birth Cohort Study (JA-Kids Birth Cohort) included 3,517 women enrolled during pregnancy. Information was extracted from interviewer-administered questionnaires which recorded social, demographic, medical and obstetric information during pregnancy. The Edinburgh Postnatal Depression scale (EPDS) was used to screen for depression, with scores ?13 considered indicative of a high likelihood of depression. Bivariate analysis examined associations between depressive symptoms and: age, income, financial difficulties, perceived social support, perceived partner infidelity, previous child-bearing unions and children with the current partner. Obstetric factors were also explored and included gravidity, prior adverse pregnancy outcome and complications from previous pregnancies. Variables that predicted the likelihood of depression based on an EPDS cut score of 13 were evaluated using logistic regression.One in five participants (19.6%; 95% CI 18.3-20.9%) had a high likelihood of antenatal depression (EPDS ?13). Significant predictors of high depressive symptom severity included four indicators of poor perceived social and partner support [ORs (95% CI) ranged from: 1.61 (1.07-2.43); p = 0.024 to 3.14(1.69-5.84); p< 0.001], perceived partner infidelity [1.86 (1.36, 2.54); p<0.001], exposure to violence [2.36 (1.66-3.38); p<0.001] and financial difficulties [1.39 (1.07, 1.80); p = 0.013].Women's perceived social and partner support were strongly associated with depressive symptom severity. Within the Jamaican cultural context of unstable reproductive unions, efforts are needed to involve fathers in the antenatal care process to strategically improve the psychological well-being of new mothers which may positively influence long term developmental outcomes for their babies.

Project description:BackgroundPostpartum depression was associated with maternal suffering and diminished functioning, increased risk of marital conflict as well as adverse child outcomes. Perceived social support during pregnancy was associated with postpartum depression among women. However, its causal relationship remains unclear. Therefore, we prospectively evaluate the association between perceived social support during early pregnancy and postpartum depressive symptoms.MethodsWe prospectively examined whether perceived social support during early pregnancy affected depressive symptoms at 6 weeks postpartum in a cohort of 3310 women. Perceived social support and postpartum depression were assessed by ENRICHD Social Support Instrument (ESSI) and the postpartum Edinburgh Postpartum Depression Scale (EPDS), respectively. Prevalence of postpartum depressive symptoms was 11.4% (EPDS cutoff≥10). As a test of heterogeneity of association in subpopulations, logistic regression models were performed to analyze the association between social support and postpartum depressive symptoms in strata which were defined by the potential confounder candidates. After multiple imputation, multivariable logistic regression was performed to assess the effect of social support on postpartum symptoms in individual items and total score. Two models were built. Model I adjusted for the variables associated with social support or postpartum depression and changed the association estimates by ≥10%. Model II adjusted for all variables that may be related to social support or postpartum depression.ResultsSignificant associations between low perceived social support and postpartum depressive symptoms was found(Model I odds ratio: 1.63, 95% confidence interval: 1.15, 2.30; Model II odds ratio: 1.77, 95% confidence interval: 1.24-2.52). Stratified analyses showed that there was little evidence of heterogeneity of association in subpopulations by basic characteristics of participants.ConclusionsThese findings suggest that early intervention may be able to help protect against depression symptoms at 6 weeks postpartum.
