Time trend in depression diagnoses among acute coronary syndrome patients and a reference population from 2001 to 2009 in Denmark

Physical Activity, Mental Health and Wellbeing during the First COVID-19 Containment in New Zealand: A Cross-Sectional Study

Strategies implemented worldwide to contain COVID-19 outbreaks varied in severity across different countries, and established a new normal for work and school life (i.e., from home) for many people, reducing opportunities for physical activity. Positive relationships of physical activity with both mental and physical health are well recognised, and therefore the aim was to ascertain how New Zealand's lockdown restrictions impacted physical activity, mental health and wellbeing. Participants (n = 4007; mean ± SD: age 46.5 ± 14.7 years, 72% female, 80.7% New Zealand European) completed (10-26 April 2020) an online amalgamated survey (Qualtrics): International Physical Activity Questionnaire: Short Form; Depression, Anxiety and Stress Scale-9; World Health Organisation-Five Well-Being Index; Stages of Change Scale. Positive dose-response relationships between physical activity levels and wellbeing scores were demonstrated for estimates that were unadjusted (moderate activity OR 3.79, CI 2.88-4.92; high activity OR 8.04, CI 6.07-10.7) and adjusted (confounding variables: age, gender, socioeconomic status, time sitting and co-morbidities) (moderate activity 1.57, CI 1.11-2.52; high activity 2.85, CI 1.97-4.14). The study results support previous research demonstrating beneficial effects of regular physical activity on mental health and wellbeing. Governments may use these results to promote meeting physical activity guidelines in order to protect mental health and wellbeing during the ongoing COVID-19 restrictions and future pandemics.

Antidepressant treatment in patients following acute coronary syndromes: a systematic review and Bayesian meta-analysis

AIMS

The aim of this study is to investigate the effect of antidepressant therapy on mortality and cardiovascular outcomes in patients with acute coronary syndrome (ACS).

METHODS AND RESULTS

We systematically searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials and performed a Bayesian random-effects meta-analysis of randomized controlled trials that investigated antidepressant pharmacotherapy in patients following ACS. The primary outcome was all-cause mortality. Secondary outcomes were repeat hospitalizations and recurrent myocardial infarctions (MIs). Ten randomized controlled trials with a total of 1935 patients qualified for inclusion. Selective serotonin reuptake inhibitors were investigated in six, bupropion in three, and mirtazapine in one trial. Placebo was used as control in eight trials. There was no difference in all-cause mortality [odds ratio (OR) 0.97, 95% credible interval (CrI) 0.66-1.42] and recurrent MI (OR 0.64, 95% CrI 0.40-1.02) between patients receiving antidepressants compared with controls, whereas antidepressant therapy was associated with less repeat hospitalizations (OR 0.62, 95% CrI 0.40-0.94). In patients with ACS and concomitant depression, antidepressants reduced the odds of recurrent MI compared with usual care/placebo (OR 0.45, 95% CrI 0.25-0.81). Extended funnel plots suggest robustness of the observations.

CONCLUSIONS

Antidepressants in patients following ACS have no effect on mortality but reduce repeat hospitalizations; in patients with depression, there is a reduced risk of recurrent MI with antidepressant therapy.

The effects of physical activity and sedentary behavior in the associations between cardiovascular diseases and depression: A four-way decomposition

BACKGROUND

Negative effects of cardiovascular diseases (CVDs) on depression have been reported, but the relative contribution of physical activity (PA) and sedentary behavior (SB) to such effects remains unclear. Our objective was to precisely quantify the effects modified or mediated by PA and SB using the recently developed four-way effect decomposition.

METHODS

Our analysis included 22,117 adults (aged≥20 years) participating in the 2007-2016 National Health and Nutrition Examination Survey (NHANES). Depression was assessed by the Patient Health Questionnaire-9. Moderate recreational activity (MRA), moderate work activity (MWA), and walk or bicycle for transportation, were measured by the Global Physical Activity Questionnaire (GPAQ). A four-way decomposition was applied with PA and SB as mediator to decompose the total effects of CVDs on depression into four components: controlled direct effect (CDE), pure indirect effect (PIE), reference interaction (INT_ref), and mediated interaction effect (INT_med).

RESULTS

There were statistically significant associations between CVDs, MRA, and depression, with the adjusted odds ratios (95% confidence intervals) of being 1.73 (1.42~2.30), 1.81 (1.42~2.30), respectively. With MRA as a mediator, there were interaction and mediation effects in the associations between CVDs and depression, and the proportions attributable of INT_ref, INT_med, and PIE were 94.08% (P<0.001), 3.92% (P = 0.007), and 1.68% (P = 0.006), respectively. Furthermore, the mediation effect was statistically significant in females rather than males.

CONCLUSIONS

MRA strongly modified and mediated the effects of CVDs on depression, especially in females. Our results suggested that sufficient MRA (at least 150 min per week) was considered as requirement for preventing depression in CVDs patients in females.

Association between prescribed antidepressants and other prescribed drugs differ by gender: a nationwide register-based study in Sweden

BACKGROUND

People with depression are prescribed more drugs than people in general, partly due to comorbidity with other conditions. However, little research has been done on depression-related drug use from a gender perspective.

AIM

Examine the association between antidepressants, other types of prescribed drugs, and polypharmacy, by gender.

METHODS

Data on drugs dispensed October to December 2016 to all Swedish citizens aged 18-84 years were collected from the Swedish prescribed drug register. Logistic regression analyses were performed to examine the associations between antidepressants and other drugs, by gender.

RESULTS

For both men and women, associations were found between antidepressants and drugs for alimentary tract problems, respiratory problems, blood, nervous system, analgesics, and polypharmacy. However, for women, but not men, associations were also found for drugs for diabetes, musculoskeletal problems, dermatological problems, and systemic hormones.

CONCLUSIONS

Associations were found between antidepressants and many other types of drugs for both men and women; indicating comorbidity between depression and other conditions. Further, some of the associations between antidepressants and other drugs were found to be specific among women. Whether this indicates that men and women differ in comorbidity between depression and other conditions cannot be concluded based on this cross-sectional study. However, comorbidity impairs the possibility of recovery; in the somatic condition as well as the depression. Thus, physicians need to be aware that the association between antidepressants and other types of drugs are more common among women than men.

Young adult cognitive ability and subsequent major depression in a cohort of 666,804 Danish men

BACKGROUND

Early life cognitive ability (CA) might influence the risk of developing major depression (MD). The aim was to investigate the association between young adult CA and subsequent MD in relation to different MD disease characteristics.

METHODS

Information on CA was assessed at conscription board examinations 1957-1984 (mean age 19 years) and information on MD was based on hospital diagnosis retrieved from Danish Patient registers 1969-2015. Associations between CA and MD were examined using Cox regression analyses.

RESULTS

A total of 666,804 men (born 1939-1959) were followed and 25,841 (3.9%) developed MD during a mean follow-up of 40.8 years. Lower CA was associated with an increased risk of incident MD. The association was stronger for early-onset (<60 years) (HR_{per1SDdecrease} = 1.23; 95%CI:1.21,1.24) compared to late-onset (≥60 years) MD (HR_{per1SDdecrease} = 1.14; 95%CI:1.11,1.16), but CA was not related to number of depressive episodes. The association was stronger for single depressive episodes (HR_{per1SDdecrease} = 1.21; 95%CI:1.19,1.23) compared to recurrent depression (HR_{per1SDdecrease} = 1.13; 95%CI:1.09,1.16), while the strength of the association did not differ according to MD disease severity (ICD10: mild, moderate, and severe depression).

LIMITATIONS

The study sample only included men and only MD cases diagnosed at hospital were included which limits the generalizability.

CONCLUSION

Low CA could be a risk factor for especially early onset MD in men, whereas the influence of CA on re-occurrence seems less strong. Lower pre-morbid CA increases the risk of MD and should therefore be part of the depression risk assessment in clinical practice.

Prophylactic antidepressant treatment following acute coronary syndrome: A systematic review of randomized controlled trials

Major depressive disorder is significantly increased in patients following acute coronary syndrome resulting in twofold increased mortality compared with patients without depression. The depression diagnosis is often missed leading to considerable undertreatment. This systematic review assesses the current evidence of primary prophylactic treatment of depression in patients after acute coronary syndrome. The study protocol was prospectively registered at PROSPERO (registration number CRD42015025587). A systematic review were conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Embase, PsychINFO, CINAHL, and Cochran Library was searched. Two independent reviewers screened the records. The inclusion criteria were randomized controlled trials on adult patients with acute coronary syndrome treated prophylactically with an antidepressant intervention of any kind. A validated assessment tool should measure depression and depressive symptoms. Languages were limited to articles written in English. Six articles were included. Four studies utilized different components of case and disease management, health coaching, or relaxational audiotapes as intervention compared with usual care or with no formal program of rehabilitation. None of the studies showed any significant prophylactic effect against depression. One study with a program of health education and counselling and another study with a pharmacological antidepressant showed significant prophylactic effect on depression and depressive symptoms. All six included studies were associated with high risk of bias. There is not strong evidence of the effects of any type of routine antidepressant prophylaxis in patients following acute coronary syndrome. Further high quality studies are warranted.
