Physical activity and sedentary behavior in people with major depressive disorder: A systematic review and meta-analysis

Promoting exercise behaviour in a secure mental health setting: Healthcare assistant perspectives

Individuals with severe mental illness engage in significantly less amounts of physical activity than the general population. A secure mental health setting can exacerbate barriers to exercise, and facilitate physical inactivity and sedentary behaviour. Healthcare assistants are intimately involved in the daily lives of patients and, therefore, should be considered integral to exercise promotion in secure mental health settings. Our aim was to explore healthcare assistants' perceptions of exercise and their attitudes to exercise promotion for adult patients in a secure mental health hospital. Qualitative semi-structured interviews were conducted with 11 healthcare assistants from a large UK-based secure mental health hospital. Topics included healthcare assistants' personal experiences of exercise within a secure facility, their perceptions of exercise as an effective treatment tool for mental health, and their perceived roles and responsibilities for exercise promotion. Thematic analysis was used to analyse the data. Three main themes were identified: (i) exercise is multi-beneficial to patients, (ii) perceived barriers to effective exercise promotion, and (iii) strategies for effectives exercise promotion. Healthcare assistants considered exercise to hold patient benefits. However, core organizational and individual barriers limited healthcare assistants' exercise promotion efforts. An informal approach to exercise promotion was deemed most effective to some, whereas others committed to more formal strategies including compulsory sessions. With education and organizational support, we propose healthcare assistants are well placed to identify individual needs for exercise promotion. Their consultation could lead to more efficacious, person-sensitive interventions.

Psychological distress is related to poor health behaviours in COPD and non-COPD patients: Evidence from the CanCOLD study

BACKGROUND

Patients with psychiatric disorders (depression, anxiety) are more likely to have poor health behaviours, including higher smoking and lower physical activity (PA) levels. Smoking is a major risk factor for Chronic Obstructive Pulmonary Disease (COPD), and PA is critical for COPD management. However, no studies have assessed associations between psychological distress and these behaviours among patients with vs without COPD. This is a sub-analysis of the CanCOLD study that assessed the relationships between psychological disorders (depression, anxiety) and poor health behaviours (smoking, PA).

METHODS

717 COPD and 797 matched non-COPD individuals from the CanCOLD study, completed the Hospital Anxiety Depression Scale (HADS) to assess anxiety and depression. Smoking behaviour was self-reported pack-years smoking. The CHAMPS PA questionnaire determined calorific expenditure as a PA measure. Regressions determined relationships between anxiety/depression and health behaviours, adjusting for age, sex, BMI, GOLD stage and COPD status.

RESULTS

Across the whole sample, we observed relationships between depression (β = 1.107 ± 0.197; 95%CI = 0.691-1.462; p < .001) and anxiety (β = 0.780 ± 0.170; 95%CI = 0.446-1.114; p < .001) and pack years. Higher depression (β = -0.220 ± 0.028; 95%CI = -0.275 to -0.165; p < .001) and anxiety (β = -0.091 ± 0.025; 95%CI = -0.139 to -0.043; p < .001) scores were related to lower PA. These associations were comparable across COPD and non-COPD patients.

CONCLUSIONS

Results showed that higher levels of anxiety and depression were related to higher cumulative smoking and lower levels of PA in patients with and without COPD, suggesting symptoms of psychological distress is similarly associated with poorer health behaviours in COPD and non-COPD individuals. Future studies need to determine if treating symptoms of psychological distress can improve health behaviours and outcomes in this population.

Depressive symptoms, handgrip strength, and weight status in US older adults

BACKGROUND

Handgrip strength is a valid indicator of broader physical functioning. Handgrip strength and weight status have been independently associated with depressive symptoms in older adults, but no study has yet investigated the relationships between all three in older US adults. This study investigated the relationship between physical function and depressive symptoms by weight status in older US adults.

METHODS

Cross-sectional data were analysed from the National Health and Nutrition Examination Survey waves 2011 to 2012 and 2013 to 2014. Physical function was assessed using a grip strength dynamometer. Depressive symptoms were assessed using the self-reported Patient Health Questionnaire-9. Weight status was assessed using Body Mass Index (BMI) and participants were categorised as normal weight (< 25 kg/m²), overweight (25 to < 30 kg/m²), and obese (≥ 30.0 kg/m²). Associations between depressive symptoms and hand grip strength were estimated by gender-specific multiple linear regressions and BMI stratified multivariable linear regression.

RESULTS

A total of 2,812 adults (54% female, mean age 69.2 years, mean BMI 29.2 kg/m²) were included. Women with moderate to severe depressive symptoms had 1.60 kg (95% CI: 0.91 to 2.30) lower hand grip strength compared to women with minimal or no depressive symptoms. No such association was observed in men. Among those with obesity, men (-3.72 kg, 95% CI: -7.00 to -0.43) and women (-1.83 kg, 95% CI: -2.87 to -0.78) with moderate to severe depressive symptoms both had lower handgrip strength.

CONCLUSION

Among older US adults, women and people who are obese and depressed are at the greatest risk of decline in physical function.

Associations of physical activity and depression: Results from the Irish Longitudinal Study on Ageing

Physical activity (PA) can protect against depression, but few studies have assessed whether meeting PA guidelines is sufficient, or if benefits can be derived from greater volumes of PA. The present study examines cross-sectional and prospective associations between different volumes of moderate-to-vigorous PA (MVPA) and walking, and depressive symptoms and status. Participants (n = 4556; 56.7% female) aged ≥ 50 years completed the International PA Questionnaire (IPAQ) at baseline and the Center for Epidemiological Studies Depression Scale at baseline and two years later. Prevalence and incidence of depression were 9.0% (n = 410) and 5.0% (n = 207), respectively. After full adjustment, odds of prevalent depression were: 40% (OR = 0.60, 95%CI: 0.48-0.76) lower among those meeting PA guidelines; 23% (OR = 0.77, 0.49-1.21) and 43% (OR = 0.57, 0.45-0.73) lower among those in moderate and high categories, respectively; and, 22% (OR = 0.78, 0.61-1.01) and 44.0% (OR = 0.56, 0.42-0.74) lower among those in moderate and high walking tertiles, respectively. Odds of incident depression were: 23% (OR = 0.77, 0.58-1.04) lower among those meeting PA guidelines; 37% (OR = 0.63, 0.32-1.22) and 20.0% (OR = 0.80, 0.59-1.09) lower among those in moderate and high categories, respectively; and, 21% (OR = 0.79, 0.56-1.12) and 25% (OR = 0.75, 0.52-1.07) lower among those in moderate and high walking tertiles, respectively. Moderate and high volumes of MVPA were significantly associated with lower odds of concurrent depression, and significantly and non-significantly associated with reduced odds of incident depression, respectively. Meeting recommended levels of MVPA and walking were associated with significantly lower odds of concurrent depression, and non-significantly reduced odds of the development of depression over two years.

Associations between active travel and physical multi-morbidity in six low- and middle-income countries among community-dwelling older adults: A cross-sectional study

BACKGROUND

There is little evidence on the potential health benefits of active travel in low- and middle-income countries (LMICs). The aim of this study was to assess the association between levels of active travel and physical multi-morbidity (i.e., two or more chronic physical conditions) and individual physical conditions among community-dwelling adults aged 65 or older in six LMICs.

METHODS

Data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, South Africa). Active travel (minutes / week) was assessed with questions of the Global Physical Activity Questionnaire (GPAQ) and presented in tertiles. Eleven chronic conditions (angina, arthritis, asthma, chronic back pain, chronic lung disease, diabetes, edentulism, hearing problems, hypertension, stroke, visual impairment) were assessed by self-report of diagnosis, symptoms, or blood pressure measurement. Multivariable logistic regression analysis was conducted to assess the association between levels of active travel, physical conditions and physical multi-morbidity.

RESULTS

The final sample consisted of 14,585 individuals aged ≥65 years (mean age = 72.6±0.1 years; 54.9% female). In the fully adjusted model, compared to the highest tertile, those in the lowest tertile of active travel had a 1.28 (95%CI = 1.06-1.54) times higher odds for physical multi-morbidity. The association between active travel and physical multi-morbidity was significantly mediated by affect (14.4%) and cognition (9.7%). With regard to individual conditions, hearing problems, hypertension, stroke, and visual impairment were particularly strongly associated with less active travel.

CONCLUSION

The current data suggest that lower levels of active travel are associated with the presence of physical health conditions and physical multi-morbidity. This multi-national study offers potentially valuable insight for a number of hypotheses which may influence this relationship, although testing with longitudinal studies is needed.

Correlates of Physical Activity Among Middle-Aged and Older Adults With Hazardous Drinking Habits in Six Low- and Middle-Income Countries

We investigated physical activity (PA) correlates among middle-aged and older adults (aged ≥50 years) with hazardous drinking patterns in six low- and middle-income countries. Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. Hazardous drinking was defined as consuming >7 (females) or >14 (males) standard drinks per week. Participants were dichotomized into low (i.e., not meeting 150 min of moderate PA/week) and moderate-high physically active groups. Associations between PA and a range of correlates were examined using multivariable logistic regressions. The prevalence of low PA in 1,835 hazardous drinkers (60.5 ± 13.1 years; 87.9% males) was 16.2% (95% confidence interval [13.9%, 18.9%]). Older age, living in an urban setting, being unemployed, depression, underweight, obesity, asthma, visual impairment, poor self-rated health, and higher levels of disability were identified as significant PA correlates. The current data provide important guidance for future interventions to assist older hazardous drinkers to engage in regular PA.

Additive Effect of Physical Activity and Sedentary Time on Depressive Symptoms in Rural Japanese Adults: A Cross-Sectional Study

BACKGROUND

Previous studies have reported an additive effect of moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) on depressive symptoms. However, no studies have been conducted in rural community settings. This cross-sectional study investigated whether the additive effect of MVPA and ST was associated with depressive symptoms in rural Japanese adults.

METHODS

We identified 2,814 participants from health examinations conducted in Shimane, rural Japan, in 2012 and analyzed data from 1,958 participants. We assessed depressive symptoms using the Zung Self-Rating Depression Scale and measured the total time spent on MVPA and ST using a Japanese short version of the International Physical Activity Questionnaire. Poisson regression analysis examined the prevalence ratios (PR) of depressive symptoms in nine category combinations of MVPA level (no, insufficient, or sufficient MVPA) and ST level (high, moderate, or low ST).

RESULTS

A total of 117 (6.0%) participants had depressive symptoms. Compared with the reference category (no MVPA/high ST), multivariate analysis showed that the likelihood of depressive symptoms was significantly lower in the sufficient MVPA/low ST category (PR 0.23; 95% confidence intervals [CI], 0.08-0.66), insufficient MVPA/low ST category (PR 0.37; 95% CI, 0.16-0.86), and insufficient MVPA/moderate ST category (PR 0.39; 95% CI, 0.17-0.90).

CONCLUSION

Analysis of the additive effect of MVPA and ST showed that the combinational category of sufficient MVPA and low ST had the lowest prevalence of depressive symptoms in rural Japanese adults. Moderate ST and low ST showed significantly lower likelihoods of depressive symptoms, regardless of insufficient MVPA.

Associations between TV viewing and depressive symptoms among 60,202 Brazilian adults: The Brazilian national health survey

BACKGROUND

Our aim was to examine associations between depression and time spent in TV viewing in a representative sample of Brazilian adults.

METHODS

Data from the Brazilian National Health Survey (Pesquisa Nacional de Saúde - PNS in Portuguese) (n =60,202; ≥18 years) were used. Time spent TV viewing (h/day) was elicited via interview. Depression was evaluated through the Patient Health Questionnaire-9. Chronological age, educational status, employment status, alcohol use, tobacco smoking and body mass index were covariates. Descriptive statistics (mean and 95% confidence interval) and adjusted logistic regression models were applied.

RESULTS

Five or more hours as well as less than 1 h of TV viewing was associated with increased depression (men: <1 h OR = 1.89, 95%CI = 1.40-2.54; ≥5 h OR = 2.69, 95%CI = 1.88-3.83; women: <1 h OR = 1.50, 95%CI = 1.25-1.81; ≥5 h OR = 1.65, 95%CI = 1.35-2.03) when compared to 2-2.99 h of TV viewing.

CONCLUSION

More than 5 h/day seems to be associated with a higher risk for depression among Brazilian adults (except for older adults). Less than 1 h TV viewing might be a measure-of-proxy for a lower socio-economic status, which is a known risk factor for depression.

Mapping risk factors for depression across the lifespan: An umbrella review of evidence from meta-analyses and Mendelian randomization studies

The development of depression may involve a complex interplay of environmental and genetic risk factors. PubMed and PsycInfo databases were searched from inception through August 3, 2017, to identify meta-analyses and Mendelian randomization (MR) studies of environmental risk factors associated with depression. For each eligible meta-analysis, we estimated the summary effect size and its 95% confidence interval (CI) by random-effects modeling, the 95% prediction interval, heterogeneity with I2, and evidence of small-study effects and excess significance bias. Seventy meta-analytic reviews met the eligibility criteria and provided 134 meta-analyses for associations from 1283 primary studies. While 109 associations were nominally significant (P < 0.05), only 8 met the criteria for convincing evidence and, when limited to prospective studies, convincing evidence was found in 6 (widowhood, physical abuse during childhood, obesity, having 4-5 metabolic risk factors, sexual dysfunction, job strain). In studies in which depression was assessed through a structured diagnostic interview, only associations with widowhood, job strain, and being a Gulf War veteran were supported by convincing evidence. Additionally, 8 MR studies were included and provided no consistent evidence for the causal effects of obesity, smoking, and alcohol consumption. The proportion of variance explained by genetic risk factors was extremely small (0.1-0.4%), which limited the evidence provided by the MR studies. Our findings suggest that despite the large number of putative risk factors investigated in the literature, few associations were supported by robust evidence. The current findings may have clinical and research implications for the early identification of individuals at risk for depression.

The association of depression and all-cause and cause-specific mortality: an umbrella review of systematic reviews and meta-analyses

BACKGROUND

Depression is a prevalent and disabling mental disorder that frequently co-occurs with a wide range of chronic conditions. Evidence has suggested that depression could be associated with excess all-cause mortality across different settings and populations, although the causality of these associations remains unclear.

METHODS

We conducted an umbrella review of systematic reviews and meta-analyses of observational studies. PubMed, PsycINFO, and Embase electronic databases were searched through January 20, 2018. Systematic reviews and meta-analyses that investigated associations of depression and all-cause and cause-specific mortality were selected for the review. The evidence was graded as convincing, highly suggestive, suggestive, or weak based on quantitative criteria that included an assessment of heterogeneity, 95% prediction intervals, small-study effects, and excess significance bias.

RESULTS

A total of 26 references providing 2 systematic reviews and data for 17 meta-analytic estimates met inclusion criteria (19 of them on all-cause mortality); data from 246 unique studies (N = 3,825,380) were synthesized. All 17 associations had P < 0.05 per random effects summary effects, but none of them met criteria for convincing evidence. Associations of depression and all-cause mortality in patients after acute myocardial infarction, in individuals with heart failure, in cancer patients as well as in samples from mixed settings met criteria for highly suggestive evidence. However, none of the associations remained supported by highly suggestive evidence in sensitivity analyses that considered studies employing structured diagnostic interviews. In addition, associations of depression and all-cause mortality in cancer and post-acute myocardial infarction samples were supported only by suggestive evidence when studies that tried to adjust for potential confounders were considered.

CONCLUSIONS

Even though associations between depression and mortality have nominally significant results in all assessed settings and populations, the evidence becomes weaker when focusing on studies that used structured interviews and those that tried to adjust for potential confounders. A causal effect of depression on all-cause and cause-specific mortality remains unproven, and thus interventions targeting depression are not expected to result in lower mortality rates at least based on current evidence from observational studies.

Correlates of sedentary behavior in 2,375 people with depression from 6 low- and middle-income countries

OBJECTIVE

Sedentary behaviour (SB) is harmful for health and well-being and may be associated with depression. However, little is known about the correlates of SB in people with depression. Thus, we investigated SB correlates among community-dwelling adults with depression in six low- and middle-income countries.

METHODS

Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. The analysis was restricted to those with DSM-IV Depression or receiving depression treatment in the last 12 months. Self-reported time spent sedentary per day was the outcome. High SB was defined as ≥8 hours of SB per day. The correlates (sociodemographic and health-related) of SB were estimated by multivariable linear and logistic regression analyses.

RESULTS

In 2375 individuals with depression (mean age=48.0 years; 60.7% female), the prevalence of high SB was 11.1% (95%CI=8.2%-14.9%), while the mean (±SD) time spent sedentary was 215 (±192) minutes per day. Socio-demographic factors significantly associated with high SB were older age and being unmarried, being male and being unemployed. In other domains, no alcohol consumption, current smoking, mild cognitive impairment, bodily pain, arthritis, stroke, disability, and lower levels of social cohesion, COPD, visual impairment, and poor self-rated health was associated with greater time spent sedentary.

CONCLUSION

Our data suggest that future interventions seeking to reduce SB among individuals with depression may target at risk groups based on identified sociodemographic correlates while the promotion of social cohesion may have the potential to increase the efficacy of future public health initiatives. From a clinical perspective, bodily pain and somatic co-morbidities need to be taken into account.

Depression and peripheral inflammatory profile of patients with obesity

This narrative review will present and discuss clinical data from 16 cross-sectional and 6 longitudinal studies examining the relationship between body mass index (BMI), symptoms of depression and peripheral inflammation. Our aim is to determine which of obesity and depression contributes best to the peripheral low-grade inflammation frequently associated to both conditions. Studies including a complete evaluation of inflammatory markers are scarce and high levels of interleukin-6 (IL-6) and C-reactive protein (CRP) are the most consistent findings associated with obesity and symptoms of depression. Among the cross-sectional studies, seven studies, including a total of 9421 individuals, pointed to BMI as the major factor associated with systemic low-grade inflammation. However, in four studies, including 16,837 individuals, CRP levels remained associated with the symptoms of depression even after correction for BMI, suggestion that in the absence of overweight or obesity other sources of peripheral inflammation might contribute to presence of depressive symptoms. Additionally, another five studies, including 5569 individuals failed to find an association between depression and peripheral inflammation, reinforcing the heterogeneity of this condition. In the longitudinal data, changes in BMI were associated with a reduction in depressive scores at follow-up, after bariatric surgery or after diet. In four longitudinal studies, high levels of CRP were found to be associated with depression even after adjustment for BMI and weight loss, further corroborating the idea that other sources of peripheral inflammation might contribute to depressive symptoms. Thus it seems that both obesity and depressive symptoms can contribute to peripheral inflammation, and once installed the presence of inflammation can contribute to several behavioral alterations that reinforce the cyclic pattern of co-occurrence observed in patients with obesity and MDD. Future clinical studies should focus on strategic efforts to collect new data and to improve or standardize methods for the evaluation of depression, body composition and a more complete inflammatory profile. These approaches are essential for the development of pharmacological and/or non-pharmacological strategies designed to break this cyclic pattern of co-occurrence.

The Epidemiology of Depressive Symptoms and Poor Sleep: Findings from the English Longitudinal Study of Ageing (ELSA)

PURPOSE

The reasons for the comorbidity between depressed mood and poor sleep are not well understood.

METHOD

Participants were 5172 adults aged 50 years and older from the English Longitudinal Study of Ageing. Sleep was measured via self-report and depressive symptoms using the Centre for Epidemiological Studies Depression scale.

RESULTS

Greater depressive symptoms and sleep complaints were associated with female sex, non-cohabitation, relative poverty, smoking, infrequent physical activity, infrequent alcohol consumption, higher body mass index (BMI), diagnosis of hypertension, coronary heart disease, diabetes/high blood glucose, pulmonary disease, arthritis, and higher levels of fibrinogen and C-reactive protein (all p < 0.05). At a 4-year follow-up, depressive symptoms and sleep complaints were both predicted by baseline depressive symptoms and sleep complaints, relative poverty, smoking, physical inactivity, BMI, and arthritis (all p < 0.05).

CONCLUSION

Depressive symptoms and sleep complaints share a range of correlates cross-sectionally and prospectively. These findings highlight the common comorbidity between depressive symptoms and sleep complaints underscoring the need for further research to understand their combined detrimental effect on long-term health and wellbeing.

Visceral adipose tissue in patients with severe mental illness

Background Severe mental illnesses (SMIs), i.e. major depression, schizophrenia and bipolar disorder, are associated with an elevated risk for the development of type-2 diabetes mellitus and cardiovascular disorders. Several factors have been associated with increased cardiometabolic morbidity and mortality in SMI, including lifestyle factors (smoking, inactivity, unhealthy diet), endocrine and immunologic alterations; however, the underlying mechanisms remain to be fully uncovered. It is now well accepted that visceral adipose tissue (VAT) promotes the development of cardiometabolic disorders, at least in part by inflammatory and metabolic functions. Methods This paper reviews studies concerning VAT, with special focus on intra-abdominal and pericardial adipose tissue, in SMI. Results In patients with SMI, several studies have been performed concerning VAT. Most of these studies reported alterations of VAT particularly in patients with major depression and schizophrenia, independent of body weight and body mass index. Some of the studies also reported an increased cardiometabolic risk. Conclusion Patients with SMI are at increased risk of developing cardiometabolic disorders, and display increased amounts of VAT. As studies so far were mainly performed on patients before the onset of cardiometabolic disorders, VAT may serve as a biomarker for patients with SMI to assess cardiometabolic risks beyond established risk scores. Further, interventions aiming at reducing VAT in SMI are highly recommended in long-term multimodal treatment plans.

Relationship between sedentary behavior and depression: A mediation analysis of influential factors across the lifespan among 42,469 people in low- and middle-income countries

BACKGROUND

Sedentary behavior (SB) is associated with diabetes, cardiovascular disease and low mood. There is a paucity of multi-national research investigating SB and depression, particularly among low- and middle-income countries. This study investigated the association between SB and depression, and factors which influence this.

METHODS

Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. Depression was based on the Composite International Diagnostic Interview. The association between depression and SB (self-report) was estimated by multivariable linear and logistic regression analyses. Mediation analysis was used to identify influential factors.

RESULTS

A total of 42,469 individuals (50.1% female, mean 43.8 years) were included. People with depression spent 25.6 (95%CI8.5-42.7) more daily minutes in SB than non-depressed participants. This discrepancy was most notable in adults aged ≥ 65y (35.6min more in those with depression). Overall, adjusting for socio-demographics and country, depression was associated with a 1.94 (95%CI1.31-2.85) times higher odds for high SB (i.e., ≥ 8h/day). The largest proportion of the SB-depression relationship was explained by mobility limitations (49.9%), followed by impairments in sleep/energy (43.4%), pain/discomfort (31.1%), anxiety (30.0%), disability (25.6%), cognition (16.1%), and problems with vision (11.0%). Other health behaviors (physical activity, alcohol consumption, smoking), body mass index, and social cohesion did not influence the SB-depression relationship.

CONCLUSION

People with depression are at increased risk of engaging in high levels of SB. This first multi-national study offers potentially valuable insight for a number of hypotheses which may influence this relationship, although testing with longitudinal studies is needed.

Acute Bouts of Exercising Improved Mood, Rumination and Social Interaction in Inpatients With Mental Disorders

Background: Studies at the macro level (such as longer-term interventions) showed that physical activity impacts positively on cognitive-emotional processes of patients with mental disorders. However, research focusing on the immediate impact of acute bouts of exercise (micro level) are missing. The aim of the present study was therefore to investigate whether and to what extent single bouts of moderately intense exercise can influence dimensions of psychological functioning in inpatients with mental disorders. Method: 129 inpatients (mean age: 38.16 years; 50.4% females) took part and completed a questionnaire both immediately before and immediately after exercising. Thirty inpatients completed the questionnaires a second time in the same week. The questionnaire covered socio-demographic and illness-related information. Further, the questionnaire asked about current psychological states such as mood, rumination, social interactions, and attention, tiredness, and physical strengths as a proxy of physiological states. Results: Psychological states improved from pre- to post-session. Improvements were observed for mood, social interactions, attention, and physical strengths. Likewise, rumination and tiredness decreased. Mood, rumination, and tiredness further improved, when patients completed the questionnaires the second time in the same week. Conclusion: At micro level, single bouts of exercise impacted positively on cognitive-emotional processes such as mood, rumination, attention and social interactions, and physiological states of tiredness and physical strengths among inpatients with mental disorders. In addition, further improvements were observed, if patients participated in physical activities a second time.

[The effective of facial exercises on the mental health in elderly adults]

AIM

Although it is well documented that exercising is good for the mental health and cognitive function as well as the physical condition in elderly people, exercising is difficult in elderly individuals with a low motor function. To develop an exercise program targeting elderly individuals unsuited for whole-body exercises, we assessed the effects of facial exercises on the mental health in healthy elderly people.

METHODS

Community-dwelling older adults (N = 75, age range = 65-87 years) were randomly divided into a facial exercises group and a wait-listed control group. A facial exercises program of 30 min was given twice a week for 12 weeks. This program consisted of rhythmic facial movement, muscle stretching, facial yoga, and Tanden breathing. The GHQ-12 for mental health were administered to both groups before and after the 12-week study period. In addition, the facial expression and tongue muscle power were measured.

RESULTS

Fifty-three participants completed the protocol. In the intervention group, the GHQ-12, facial expression, and tongue muscle power improved post-intervention.

CONCLUSIONS

These results suggest that facial exercises are effective in improving the mental health, facial expression, tongue muscle power of elderly people, and that exercises may be useful as a therapeutic modality in this population.

Physical activity and sedentary behavior in patients with Systemic Lupus Erythematosus

Introduction

The aim of this study was to evaluate the proportion of patients with Systemic Lupus Erythematosus (SLE) who did not met the WHO recommendations for physical activity and to evaluate the amount of time spent in sedentary behavior.

Methods

SLE patients were consecutively enrolled in a cross sectional study. The type and the time spent in physical activity and sedentary behavior were evaluated using the IPAQ short form questionnaire. The adequate physical activity was defined according to the 2010 WHO recommendations for health and the sedentary behavior according to the 2017 SBRN consensus. We also assessed quality of life using SF-36, mood disorders using BDI and HAM-H, fatigue using Facit-Fatigue and sleep disorders using PSQI scores.

Results

Physical activity was not sufficient to meet WHO recommendations in 56 of 93 SLE patients (60%). SLE patients spent a median (95% range) of 180 (0–600) minutes everyday in sedentary activities. The length of daily sedentary time was more than 6 hours in 25% of SLE patients. In multivariable analysis, the factors associated to the probability of not meeting WHO criteria was only the time of exposure to antimalarials (OR 0.88, p 0.03) and the factors related to the probability of being in the upper tertile of sedentary time (more than 270 minutes) were age (OR 1.04, p 0.02), disease activity expressed by SELENA-SLEDAI score (OR 1.2, p 0.01) and Facit-fatigue score (OR 0.94, p 0.04).

Conclusion

A relevant proportion of SLE patients were inadequately physically active. It is essential to improve the awareness of the importance of increase physical activity and reduce sedentary time. A better control of disease activity and fatigue and a prolonged use of antimalarials could help to reach this notable goal.

High prevalence of depressive symptoms in a national sample of adults in Indonesia: Childhood adversity, sociodemographic factors and health risk behaviour

BACKGROUND

The aim of this study was to investigate depressive symptoms and their association with sociodemographic factors, stressors and support, including childhood adversity, health status risk and behaviour in Indonesia.

METHOD

In a cross-sectional national population survey in 2014-15 in Indonesia, 31442 adults (mean age 37.3 years, SD = 14.9, age range 15-101 years) responded to the Centers for Epidemiologic Studies Depression Scale (CES-D-10) and various other measures.

RESULTS

Overall, 15.0% of participants reported moderate and 6.9% severe depressive symptoms, or 21.8% moderate or severe depressive symptoms (21.4% among men and 22.3% among women). In multivariable logistic regression among both men and women, sociodemographic factors (younger age, poor subjective economic background, being unemployed, residing in Java and main island groups), stressors (childhood hunger and poor or fair self-rated health status and having experienced disasters), lack of social trust and religiosity, having one or more chronic conditions, tobacco use and soft drink consumption were positively and obesity negatively associated with moderate or severe depressive symptoms.

CONCLUSION

High rates (21.8%) of depressive symptoms were found. Several risk factors including sociodemographic factors such as younger age, stressors, lack of social support, health risk status and behaviour variables were identified which can be utilized in guiding interventions.

Physical activity correlates among people with psychosis: Data from 47 low- and middle-income countries

BACKGROUND

People with schizophrenia engage in low levels of physical activity (PA). However, few large-scale studies have investigated the factors that may influence PA participation in individuals with psychosis and data from low- and middle-income countries (LMICs) is especially scarce. Thus, we investigated PA correlates in a large sample of people with a psychosis diagnosis across 47 LMICs.

METHODS

Cross-sectional data from the World Health Survey, restricting to those with a self-reported lifetime diagnosis of schizophrenia/psychotic disorder, was analyzed. PA was assessed by the International Physical Activity Questionnaire (IPAQ) and participants were dichotomized into those that do and do not (low PA) meet the minimum recommended PA weekly targets (≥150min). A range of socio-demographic, health behavior, and mental and physical health variables were examined using random effects logistic regression.

RESULTS

Overall 2407 people (mean 42.0years, 41.5% males) with schizophrenia/psychosis were included. The prevalence of low PA was 39.2% (95%CI=37.0%-41.2%). Male sex (odds ratio (OR)=1.33), increasing age, unemployment (vs. employed OR=2.50), urban setting (vs. rural OR=1.75), inadequate fruit consumption (vs. adequate fruit intake OR=3.03), depression (OR=1.33), sleep/energy disturbance, and mobility limitations were significantly associated with low PA. Marital status, education, wealth, smoking, vegetable and alcohol consumption, anxiety, cognition, pain, and chronic medical conditions were not significant correlates.

CONCLUSION

PA is influenced by a range of factors among people with psychosis. These correlates should be considered in interventions aiming to facilitate PA in psychotic individuals living in LMICs.

Psychosocial Outcomes 12 Months Following a Dose-Response Aerobic Exercise Intervention in Postmenopausal Women

BACKGROUND

We previously reported no postintervention differences in quality of life and other psychosocial outcomes when comparing 12-month high versus moderate volume of aerobic exercise in postmenopausal women. Here, we report the 24-month follow-up for these outcomes.

METHODS

At 24-month follow-up, 333 out of 400 postmenopausal women were randomized to a year-long intervention of 150 (moderate) or 300 (high) minutes per week of aerobic exercise returned a battery of self-reported measures assessing quality of life, psychosocial outcomes, and sleep quality, also assessed at baseline and postintervention. Intention-to-treat analyses using linear models were conducted to determine the changes between baseline and 24-month follow-up.

RESULTS

No significant effects between moderate- and high-volume aerobic exercise groups were observed among any outcomes. There was some evidence of effect moderation by baseline body mass index in relation to quality of life, psychosocial outcomes, and sleep quality, where obese women benefitted from the moderate-volume exercise and nonobese women benefitted from the high-volume exercise prescription.

CONCLUSION

Although high-volume aerobic exercise did not improve psychosocial outcomes when compared with moderate volume at the 24-month follow-up, we did observe potential effect of moderation between obese and nonobese women. Confirmation of these interactions is warranted in this population.

Improving the health of mental health staff through exercise interventions: a systematic review

BACKGROUND

Exercise interventions are efficacious in reducing cardiometabolic risk and improving symptoms in people with severe mental illness, yet evidence guiding the implementation and scalability of such efforts is lacking. Given increasing efforts to address the disparity in physical health outcomes facing people with a mental illness, novel approaches to increasing adoption of effective interventions are required. Exercise interventions targeting mental health staff may improve staff health while also creating more positive attitudes towards the role of lifestyle interventions for people experiencing mental illness.

AIMS

We aimed to determine the feasibility, acceptability and effectiveness of exercise interventions delivered to staff working in mental health services.

METHOD

A systematic review was conducted from database inception, until November 2017. Studies recruiting staff participants to receive an exercise intervention were eligible for inclusion.

RESULTS

Five studies met the inclusion criteria. Physical health interventions for mental health staff were feasible and acceptable with low dropout rates. Reductions in anthropometric measures and work-related stress were reported.

CONCLUSIONS

Limited evidence suggests that exercise interventions targeting mental health staff are feasible and acceptable. Further research is required to determine the efficacy of such interventions and the impact such strategies may have on staff culture and patient outcomes.

Physical activity correlates in people with mild cognitive impairment: findings from six low- and middle-income countries

OBJECTIVES

Despite promising research showing that physical activity (PA) might improve cognitive functioning in people with mild cognitive impairment (MCI), people with MCI are less physically active compared with the general population. Therefore, the aim of this study was to assess PA correlates among community-dwelling older people with MCI in six low- and middle-income countries.

DESIGN

Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analysed.

METHODS

PA level was assessed by the Global Physical Activity Questionnaire. 4854 participants with MCI (mean age 64.4 years; 55.1% females) were grouped into those who do and do not (low PA) meet the 150 min of moderate-to-vigorous PA per week recommendation. Associations between PA and the correlates were examined using multivariable logistic regressions.

RESULTS

The prevalence of low PA was 27.4% (95% confidence interval = 25.0-30.0). In the multivariable analysis, older age and unemployment were the only sociodemographic correlates of low PA. The significant positive correlates of low PA in other domains included depression, being underweight, obesity, asthma, chronic lung disease, hearing problems, visual impairment, slow gait, weak grip strength, poor self-rated health, and lower levels of social cohesion.

CONCLUSIONS

The current data illustrate that a number of sociodemographic and health factors are associated with PA levels among older people with MCI. The promotion of social cohesion may increase the efficacy of public health initiatives while from a health care perspective, somatic co-morbidities, muscle strength and slow gait need to be considered when activating those at risk for dementia.

Cotinine: A Therapy for Memory Extinction in Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a mental disorder that may develop after exposure to exceptionally threatening or unescapable horrifying events. Actual therapies fail to alleviate the emotional suffering and cognitive impairment associated with this disorder, mostly because they are ineffective in treating the failure to extinguish trauma memories in a great percentage of those affected. In this review, current behavioral, cellular, and molecular evidence supporting the use of cotinine for treating PTSD are reviewed. The role of the positive modulation by cotinine of the nicotinic acetylcholine receptors (nAChRs) and their downstream effectors, the protection of astroglia, and the inhibition of microglia in the PTSD brain are also discussed.

Vigorous physical activity, perceived stress, sleep and mental health among university students from 23 low- and middle-income countries

Background Vigorous physical activity (VPA) may be beneficial for mental health. The aim of the study was to investigate cross-sectional associations between VPA, perceived stress, sleep quality and quantity and mental health among university students. Methods In a cross-sectional study, using anonymous questionnaires, data was collected from 15122 (42.1% male and 57.9% female) university students [mean age 20.6, standard deviation (SD) = 2.0] from 23 countries in the Americas, Africa and Asia. They were assessed using the International Physical Activity Questionnaire (short version), and measures of sociodemographic, health status, health behaviour and anthropometrics. Results Students who met VPA recommendations were less likely to report perceived stress, more likely to report subjective good health and depression than students without VPA. There was no association between VPA and sleep quality and quantity and PTSD symptoms. Conclusion This study only found partial benefits of VPA in relation to well-being of university students.

Correlates of low physical activity across 46 low- and middle-income countries: A cross-sectional analysis of community-based data

Physical inactivity accounts for 5.5% of all avoidable global deaths. However, a paucity of multinational studies, particularly in low- and middle-income countries (LMICs), has investigated correlates of physical activity (PA). Thus, we assessed the correlates of PA using cross-sectional, community-based data of the World Health Survey including 46 LMICs. PA was assessed by the International Physical Activity Questionnaire (IPAQ) and participants were dichotomized into those who do (≥150min moderate-vigorous PA per week) and do not (<150min=low PA) comply with the World Health Organization (WHO) PA recommendations. Multivariable logistic regression was used to assess the PA correlates. The prevalence of low PA in 206,356 persons (mean age 38.4years; 49.6% males) was 29.2% (95%CI=28.3%-30.0%). In the overall sample, female sex, not married/cohabiting, high education and wealth, unemployment, and urban setting were significant sociodemographic correlates of low PA. In terms of other correlates, inadequate fruit and vegetable intake, subsyndromal depression, worse sleep/energy and cognition, visual impairment, hearing problems and asthma were associated with not meeting the WHO recommendations. There were some variations in the correlates depending on age and sex. Interventions should be developed that operate at multiple levels of influence and take into account age- and gender-related PA patterns in order to assist people in LMICs to comply with the WHO PA recommendations. Researchers, funding bodies, practitioners and policymakers in education, mental and physical health, and urban planning have a critical role to play.

Physical Exercise in Major Depression: Reducing the Mortality Gap While Improving Clinical Outcomes

Major depression shortens life while the effectiveness of frontline treatments remains modest. Exercise has been shown to be effective both in reducing mortality and in treating symptoms of major depression, but it is still underutilized in clinical practice, possibly due to prevalent misperceptions. For instance, a common misperception is that exercise is beneficial for depression mostly because of its positive effects on the body ("from the neck down"), whereas its effectiveness in treating core features of depression ("from the neck up") is underappreciated. Other long-held misperceptions are that patients suffering from depression will not engage in exercise even if physicians prescribe it, and that only vigorous exercise is effective. Lastly, a false assumption is that exercise may be more harmful than beneficial in old age, and therefore should only be recommended to younger patients. This narrative review summarizes relevant literature to address the aforementioned misperceptions and to provide practical recommendations for prescribing exercise to individuals with major depression.

Impact of aerobic exercise on muscle mass in patients with major depressive disorder: a randomized controlled trial

OBJECTIVE

Sarcopenia leads to physical function impairment and at least to increasing all-cause mortality. There are notes on reduced muscle mass in patients with major depressive disorder (MDD). Whether an exercise intervention counteracts low muscle mass in patients with MDD has not been studied so far. Therefore, our study aimed at examining effects of regular aerobic exercise training on muscle mass in patients with MDD.

PARTICIPANTS AND METHODS

Thirty inpatients with MDD were included in the study, of which 20 received an additional supervised exercise program. Ten patients obtained treatment as usual. Muscle mass was measured using MRI before and 6 weeks after the training period (3 times per week for 45 minutes).

RESULTS

We found a significant effect of the exercise intervention on the amount of muscle mass depending on age, body mass index, and the physical activity score (P=0.042).

CONCLUSION

Among other positive effects, regular exercise increases muscle mass in patients with MDD and, therefore, should be recommended as an additional treatment tool.

Psychiatric In-Patients Are More Likely to Meet Recommended Levels of Health-Enhancing Physical Activity If They Engage in Exercise and Sport Therapy Programs

Background: People with mental disorders engage in sedentary behaviors more often than their healthy counterparts. In Switzerland, nearly all psychiatric hospitals offer structured exercise and sport therapy as part of their standard therapeutic treatment. However, little is known about the degree to which psychiatric patients make use of these treatment offers. The aim of this study is to examine, in a sample of psychiatric in-patients (a) how many participate in the structured exercise and sport therapy programs offered by the clinic, (b) how many engage in exercise and sport activities on an individual basis, and (c) how many meet recommended levels of health-enhancing physical activity during their stay at the clinic. Furthermore, we examine whether those who engage in exercise and sport activities are more likely to meet internationally accepted physical activity recommendations. Methods: 107 psychiatric in-patients (49% women, M_age = 39.9 years) were recruited at three psychiatric clinics in the German-speaking part of Switzerland. All participants were engaged in treatment and received usual care. Based on accelerometer data, participants were classified as either meeting or not meeting physical activity recommendations (≥150 min of moderate-to-vigorous physical activity per week). Participation in structured and individually performed exercise and sport activities was assessed with the Simple Physical Activity Questionnaire. Results: In total, 57% of all patients met physical activity recommendations. 55% participated in structured exercise and sport therapy activities, whereas only 22% of all patients engaged in exercise and sport activities independently. Psychiatric patients were significantly more likely to meet recommended levels of health-enhancing physical activity if they engaged in at least 60 min per week of structured exercise and sport therapy or in at least 30 min of individually performed exercise and sport activity. Conclusions: Given that prolonged immobilization and sedentary behavior have harmful effects on patients' physical and mental well-being, promoting exercise and sport activities is an important endeavor in psychiatric care. Clinics currently succeed in involving between 50 and 60% of all patients in sufficient physical activity. While this is encouraging, more systematic efforts are needed to ensure that all patients get enough physical activity.

Impact of obesity and mood disorders on physical comorbidities, psychological well-being, health behaviours and use of health services

BACKGROUND

Albeit obesity and mood disorders frequently co-occur, few studies examined the impacts of this co-occurrence. The aim was to compare individuals with obesity and mood disorders (ObMD) to those with obesity without mood disorder in terms of physical comorbidities, psychological well-being, health behaviours and use of health services.

METHODS

Cross-sectional study using the Canadian Community Health Survey including a weighted sample of individuals with obesity (n = 1298) representing inhabitants from the province of Quebec (Canada).

RESULTS

Adjusted multivariate logistic regressions indicated that ObMD reported more physical conditions with odds ratio (OR) ranging from 1.8 [95%CI: 1.1 - 2.8] (hypertension) to 2.8 [95%CI: 1.3 - 6.0] (stomach ulcer). Also, ObMD reported poorer psychological well-being with OR ranging from 2.1 [95%CI: 1.4 - 3.3] (stress) to 25.6 [95%CI: 14.7 - 45.0] (poor perceived mental health). ObMD also reported more consultations with health professionals with OR ranging from 1.9 [95%CI: 1.0 - 3.5] (physicians) to 7.7 [95%CI: 4.2 - 14.3] (psychologists), and less healthy behaviours with OR ranging from 1.7 [95%CI: 1.1 - 2.6] (fruits and vegetables intake) to 2.1 [95%CI: 1.3 - 3.3] (tobacco).

LIMITATIONS

Self-reported data so we cannot discard the possibility of a bias in reporting. Also, given the cross-sectional design, no directional conclusion or causality about our results is possible.

DISCUSSION

The co-occurrence of mood disorder and obesity seems to be an aggravating factor of obesity-related factors because it is associated with poorer health in several areas. Interventions to prevent or manage obesity in mood disorders are necessary.

Physical activity and suicidal ideation: A systematic review and meta-analysis

BACKGROUND

A potential approach to suicide prevention that has not been closely examined, but which holds promise in terms of widespread dissemination without major side-effects, is physical activity (PA). This systematic review and meta-analysis set out to: (a) explore associations between PA and suicidal ideation (SI) levels, and (b) investigate the effect of PA interventions on SI.

METHODS

Major electronic databases were searched from inception up to 05/2017 to identify quantitative studies reporting an association between PA and SI. A quantitative correlates synthesis and random effects meta-analysis were conducted.

RESULTS

Fourteen of 21 studies in adults (67%) (n = 130,737), 7/14 (50%) in adolescents (n = 539,170) and 2/3 (67%) in older adults (n = 50,745) found a significant negative association between PA- and SI-levels. Pooled adjusted meta-analysis of 14 effect sizes over eight studies and 80,856 people found that those who were "active" versus those who were "inactive" were less likely to have SI (OR = 0.87, 95%CI = 0.76-0.98). Additionally, meeting PA guidelines conferred a significant protective effect against SI (OR = 0.91, 95%CI = 0.51-0.99, P = 0.03; N studies = 3, n people = 122,395), while not meeting guidelines was associated with increased SI (OR = 1.16, 95%CI = 1.09-1.24, P < 0.001; N = 4, n = 78,860). Data from the intervention studies (N = 3, n = 121) was mixed and limited.

LIMITATIONS

Our findings are based mainly on cross-sectional studies, while the majority of studies did not include a rigorous physical activity assessment.

CONCLUSIONS

The current study suggests that higher PA levels are associated with lower SI. However, the associations observed need to be confirmed in prospective observational studies and controlled trials.

The association between adolescent psychopathology and subsequent physical activity in young adulthood: a 21-year birth cohort study

BACKGROUND

The beneficial effects of physical activity (PA) for both physical and mental wellbeing are well established. Given that adolescence presents a critical developmental period during which life-long patterns of PA become established, the exploration of the longitudinal impact of adolescent psychopathology on adult PA status is of interest.

METHODS

We analysed prospective data from 3663 young adults who participated in the Mater-University of Queensland Study of Pregnancy. Psychopathology was measured using the Youth Self-Report (YSR) at age 14. Participants' engagement in three types of PA (vigorous exercise, moderate exercise and walking) at age 21 were dichotomised into either 'none' or 'any'. For our main analysis, we examined the association between the YSR score and subsequent PA engagement using logistic regression. We also conducted sensitivity analyses of longitudinal associations between the YSR internalising and externalising symptoms score at age 14 and PA engagement at age 21.

RESULTS

We found no longitudinal association between the total YSR score at age 14 and PA engagement at age 21. In addition, there was no longitudinal association between the YSR internalising or externalising symptoms and PA engagement.

CONCLUSION

Our findings suggest that there is no longitudinal association between adolescent psychopathology and PA in young adulthood.

Physical fitness and levels of physical activity in people with severe mental illness: a cross-sectional study

Background

Physical fitness is a crucial variable in people with severe mental illness as these people could be more independent and improve their job opportunities. The present study compared the physical fitness of physically active and inactive people with severe mental illness.

Methods

Physical fitness was evaluated in sixty-two people with severe mental illness using 11 physical tests that include strength, flexibility, balance and aerobic condition. Significant differences were found between both groups in muscle strength (handgrip test) and balance (single leg balance test and functional reach) with better performance in the group of physically active people.

Results

The results of the present study suggest that physical fitness (strength and balance) is higher in people with severe mental illness who practise regular physical activity that those who are inactive people.

Conclusions

Physical active people may have a reduced risk of falls and fractures due to their higher levels of physical fitness.

Mental health consequences of exercise withdrawal: A systematic review

OBJECTIVE

A sedentary lifestyle has been associated with mental health disorders. Many medical conditions result in the cessation of exercise, which may increase the risk of developing mental health problems. The purpose of this article is to systematically review the literature examining the effects of exercise withdrawal on mental health.

METHOD

Literature was searched using PubMed, PsycINFO, and SPORTdiscus for studies that experimentally manipulated the withdrawal of exercise and included mental health as outcome measure.

RESULTS

A total of 19 studies met inclusion criteria (total N=689 with 385 individuals participating in an exercise withdrawal condition). Exercise withdrawal consistently resulted in increases in depressive symptoms and anxiety. Other mental health outcomes were investigated infrequently. Severe mental health issues requiring clinical intervention after experimentally controlled exercise withdrawal was rare. Heterogeneity in methods and outcomes was observed, especially in terms of the duration of exercise withdrawal (range 1 to 42days, median=7days), with stronger effects if exercise withdrawal exceeded 2weeks.

CONCLUSION

Experimentally controlled exercise withdrawal has adverse consequences for mental health. These observations in healthy individuals may help to understand the onset of mental health problems in response to acute and chronic medical conditions associated with reduced physical activity. Future research is needed to investigate potential mechanisms explaining the adverse mental health consequences of cessation of exercise that will provide new targets for clinical interventions.

Effects of chair yoga therapy on physical fitness in patients with psychiatric disorders: A 12-week single-blind randomized controlled trial

INTRODUCTION

Since falls may lead to fractures and have serious, potentially fatal outcomes, prevention of falls is an urgent public health issue. We examined the effects of chair yoga therapy on physical fitness among psychiatric patients in order to reduce the risk of falls, which has not been previously reported in the literature.

METHODS

In this 12-week single-blind randomized controlled trial with a 6-week follow-up, inpatients with mixed psychiatric diagnoses were randomly assigned to either chair yoga therapy in addition to ongoing treatment, or treatment-as-usual. Chair yoga therapy was conducted as twice-weekly 20-min sessions over 12 weeks. Assessments included anteflexion in sitting, degree of muscle strength, and Modified Falls Efficacy Scale (MFES) as well as QOL, psychopathology and functioning.

RESULTS

Fifty-six inpatients participated in this study (36 men; mean ± SD age, 55.3 ± 13.7 years; schizophrenia 87.5%). In the chair yoga group, significant improvements were observed in flexibility, hand-grip, lower limb muscle endurance, and MFES at week 12 (mean ± SD: 55.1 ± 16.6 to 67.2 ± 14.0 cm, 23.6 ± 10.6 to 26.8 ± 9.7 kg, 4.9 ± 4.0 to 7.0 ± 3.9 kg, and 114.9 ± 29.2 to 134.1 ± 11.6, respectively). Additionally, these improvements were observable six weeks after the intervention was over. The QOL-VAS improved in the intervention group while no differences were noted in psychopathology and functioning between the groups. The intervention appeared to be highly tolerable without any notable adverse effects.

CONCLUSIONS

The results indicated sustainable effects of 20-min, 12-week, 24-session chair yoga therapy on physical fitness. Chair yoga therapy may contribute to reduce the risk of falls and their unwanted consequences in psychiatric patients.

Longitudinal association between physical activity engagement during adolescence and mental health outcomes in young adults: A 21-year birth cohort study

OBJECTIVE

Previous studies provide mixed evidence that physical activity engagement (PAE) in adolescence is associated with later mental health outcomes. This study aimed to examine the association between PAE at age 14 and mental health outcomes at age 21 using a large birth cohort study.

MATERIAL AND METHODS

Prospective data from the Mater-University of Queensland Study of Pregnancy, consisting of 3493 young adults, were analyzed. PAE at age 14 was estimated using self-report, and participants were categorized into; (1) frequent, (2) infrequent, or (3) no PAE group. Mental health outcomes at age 21 consisted of; (1) common mental disorders, (2) psychosis-related outcomes, and, (3) emotional and behavioral problems. The association between PAE in adolescence and later mental health outcomes in young adulthood was examined using logistic regression, adjusted for age, sex, body mass index, and adolescent psychopathology.

RESULTS

No PAE at age 14 was associated with the increased likelihood of lifetime diagnosis of any affective disorder, elevated delusional ideation, and endorsement of visual perceptual disturbance at age 21. Conversely, infrequent PAE at age 14 was associated with the decreased likelihood of subsequent lifetime diagnosis of any substance use disorder.

CONCLUSION

Our findings suggest that lack of PAE in adolescence influences some, but not all, later mental health outcomes. Interventions to increase PAE in adolescence may represent an opportunity to prevent future mental health problems.

Physical activity correlates among 24,230 people with depression across 46 low- and middle-income countries

BACKGROUND

There is a paucity of nationally representative data available on the correlates of physical activity (PA) among people with depression, especially in low- and middle-income countries (LMICs). Thus, we investigated PA correlates among community-dwelling adults with depression in this setting.

METHODS

World Health Survey data included 24,230 adults (43.1 ± 16.1 years; 36.1% male) with ICD-10 diagnoses of depression including brief depressive episode and subsyndromal depression aged ≥ 18 years from 46 LMICs. PA was assessed by the International Physical Activity Questionnaire. Participants were dichotomised into low and moderate-to-high physically active groups. Associations between PA and a range of sociodemographic, health behaviour and mental and physical health variables were examined using multivariable logistic regressions.

RESULTS

34.8% of participants with depression were physically inactive. In the multivariate analyses, inactivity was associated with male sex, older age, not being married/cohabiting, high socio-economic status, unemployment, living in an urban setting, less vegetable consumption, and poor sleep/ low energy. In addition, mobility difficulties and some somatic co-morbidity were associated with not complying with the 150min per week moderate-to-vigorous PA recommendations.

CONCLUSIONS

The current data provide guidance for future population level interventions across LMICs to help people with depression engage in regular PA.

Psychological distress and the incident risk of functional disability in elderly survivors after the Great East Japan Earthquake

BACKGROUND

We conducted a prospective cohort study to investigate whether psychological distress would have increased the incident risk of functional disability after the 2011 Great East Japan Earthquake.

METHODS

First phase data pertaining to psychological distress and other lifestyle factors were collected from 1037 subjects aged ≥ 65 years, from June to December 2011, in four affected areas of Miyagi prefecture in Japan. Psychological distress was measured by the Kessler 6-item psychological distress scale (K6), and classified into three categories (K6 score ≤ 9, 10-12, ≥ 13). Outcome data on functional disability were collected from the public Long-term Care Insurance database. Participants were followed up for about 2.6 years. The Cox model was used to calculate the multivariate hazard ratios (HRs) and 95% confidence intervals (CIs).

RESULTS

During the follow-up period, 118 participants were certified as incident disability (43.8 disability events per 1000 person-years). Compared with the lowest category (K6 score ≤ 9), participants in the highest category (K6 score ≥ 13) had a significantly higher risk of functional disability (HR = 2.65, 95% CI = 1.35-5.18, p = 0.002). In order to consider reverse causality, we conducted analysis excluding all incidents and deaths that occurred within the first year of follow-up, but our findings remained unchanged.

LIMITATIONS

We did not consider all potential confounders and use of appropriate medication.

CONCLUSIONS

The present study has demonstrated that psychological distress was associated with an increased risk of functional disability among elderly survivors of a natural disaster.

Impact of adherence to antidepressants on healthcare outcomes and costs among patients with type 2 diabetes and comorbid major depressive disorder

OBJECTIVE

To evaluate the association between adherence to antidepressants and an effect on clinical outcomes and healthcare costs in patients with major depressive disorder (MDD) and comorbid type 2 diabetes (T2D).

METHODS

This retrospective study used MarketScan claims data from January 2012 to March 2014. Study entry was the first claim for an antidepressant and a diagnosis code for MDD and T2D in the prior 6 months. Adherence and persistence with antidepressant therapy in the first 180 days were defined as medication possession ratio (MPR) ≥ 80% and length of therapy (LOT), with no treatment gap of >15 days, respectively. T2D control (HbA1c <7%), oral diabetes medication adherence, and healthcare costs were measured in the 12 month post-index period. The impact of antidepressant adherence and persistence on outcomes was assessed using multivariable analyses.

RESULTS

Among the 1361 patients included, the mean age was 59 years and 55% were women. About one-third of the patients were adherent (35.9%, mean MPR = 40%), persistent (32.0%, average LOT = 100 days), and adherent/persistent (31.2%) on antidepressants. Being adherent, persistent, or adherent/persistent to antidepressants was associated with a two-fold improvement in adherence to oral diabetes medications. Of those with HbA1c data (n = 121), adherence or adherence/persistence to antidepressants was associated with patients being five times more likely to have T2D control (odds ratio [OR]: 4.95; 95% confidence interval [CI]: 1.39, 17.59, p = .0134). Comparison between antidepressant-persistent and non-persistent patients was not significant. Mean difference in adjusted all-cause annual costs showed lower costs among antidepressant-adherent and adherent/persistent patients (adherent: -$350, 95% CI: -$462, -$247; adherent/persistent: -$1165; 95% CI: -$1280, -$1060).

CONCLUSIONS

Patients with better antidepressant adherence and adherence/persistence demonstrated better HbA1c control, with lower all-cause total and medical costs. Adherence, persistence, or adherence/persistence to antidepressants was associated with improved adherence to oral diabetes medications.
