Abstract
Objective Diet is increasingly recognized as a potentially modifiable factor influencing the onset and outcomes of psychiatric disorders. Whereas, previous research has shown long-term schizophrenia is associated with various nutritional deficiencies, this meta-analysis aimed to determine the prevalence and extent of nutritional deficits in first-episode psychosis (FEP). Method A search of electronic databases conducted in July 2017 identified 28 eligible studies, examining blood levels of 6 vitamins and 10 minerals across 2612 individuals: 1221 individuals with FEP and 1391 control subjects. Meta-analyses compared nutrient levels in FEP to nonpsychiatric controls. Clinical correlates of nutritional status in patient samples were systematically reviewed. Results Significantly lower blood levels of folate (N = 6, n = 827, g = -0.624, 95% confidence interval [CI] = -1.176 to -0.072, P = .027) and vitamin D (N = 7, n = 906, g = -1.055, 95% CI = -1.99 to -0.119, P = .027) were found in FEP compared to healthy controls. Synthesis of clinical correlates found both folate and vitamin D held significant inverse relationships with psychiatric symptoms in FEP. There was also limited evidence for serum level reductions of vitamin C (N = 2, n = 96, g = -2.207, 95% CI = -3.71 to -0.71, P = .004). No differences were found for other vitamins or minerals. Conclusions Deficits in vitamin D and folate previously observed in long-term schizophrenia appear to exist from illness onset, and are associated with worse symptomology. Further research must examine the direction and nature of these relationships (ie, mediator, moderator, or marker) with clinical status in FEP. Future trials assessing efficacy of nutrient supplementation in FEP samples should consider targeting and stratifying for baseline deficiency.

Abstract
AIM Physical activity has the potential to improve the health of patients with first-episode psychosis (FEP), yet many patients with FEP remain inactive. Exploring the theoretical basis of the motivational processes linked to the adoption and maintenance of physical activity behaviours in FEP patients can assist with the design and delivery of physical activity interventions. Within the self-determination theory and the transtheoretical model (stages of change) frameworks, we investigated motives for physical activity adoption and maintenance in FEP. METHODS Overall 56 FEP patients (20♀) (24 ± 4 years) completed the Behavioural Regulation in Exercise Questionnaire 2 to assess exercise motives, and the Patient-Centred Assessment and Counselling for Exercise to determine stage of change. Gender and setting differences in motives for physical activity were compared with unpaired t-tests. The relationship between motives for physical activity and stage of change was investigated using anova with post-hoc Scheffe tests. RESULTS No significant differences were found according to gender and setting. Multivariate analyses found significantly higher levels of amotivation and lower levels of autonomous motivation in the earlier stages of change. CONCLUSIONS Our results suggest that in FEP patients, autonomous regulations may play an important role in the adoption and maintenance of physical activity behaviours. The study provides a platform for future research to investigate the importance of autonomous motivation within physical activity interventions for this population.

Abstract
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.

Abstract
BACKGROUND Previous physical activity (PA) research in schizophrenia has relied largely upon self-report measures. However, the accuracy of this method is questionable. Obtaining accurate measurements, and determining what may influence PA levels in schizophrenia, is essential to understand physical inactivity in this population. This study examined differences in self-reported and objectively measured PA in people with schizophrenia and the general population using a large, population-based dataset from the UK Biobank. METHODS Baseline data from the UK Biobank (2007-2010) were analyzed; including 1078 people with schizophrenia (54.19 ± 8.39 years; 55% male) and 450549 without (56.44 ± 8.11; 46% male). We compared self-reported PA with objectively measured accelerometry data in schizophrenia and comparison samples. We also examined correlations between self-report and objective measures. RESULTS People with schizophrenia reported the same PA levels as those without, with no differences in low, moderate, or vigorous intensity activity. However, accelerometry data showed a large and statistically significant reduction of PA in schizophrenia; as people with schizophrenia, on average, engaged in less PA than 80% of the general population. Nonetheless, within the schizophrenia sample, total self-reported PA still held significant correlations with objective measures. CONCLUSIONS People with schizophrenia are significantly less active than the general population. However, self-report measures in epidemiological studies fail to capture the reduced activity levels in schizophrenia. This also has implications for self-report measures of other lifestyle factors which may contribute toward the poor health outcomes observed in schizophrenia. Nonetheless, self-report measures may still be useful for identifying how active individuals with schizophrenia relative to other patients.

Abstract
BACKGROUND The associations of different patterns of alcohol consumption and the incidence and persistence of depressive and anxiety symptoms in older age remain unclear. METHODS Data on 6095 adults aged ≥ 50 years old from the Irish Longitudinal Study on Aging (TILDA) was analyzed. Participants completed the CAGE instrument to screen for problematic alcohol use at baseline between October 2009 and February 2011. Outcomes were incident (assessed by the CES-D scale) and anxiety (assessed by the Hospital Anxiety and Depressive scale) symptoms after a two-year follow-up as well as persistence of probable depression and anxiety among those with a positive screen for those disorders at baseline. Associations were adjusted for potential confounders through multivariable models. RESULTS In the overall sample, problem drinking did not predict incident and persistent depression and anxiety in this sample. Among females, problem drinking increased the risk for incident depression (OR = 2.11; 95%CI = 1.12-4.00) and anxiety (OR = 2.22; 95%CI = 1.01-4.86). In addition, problem drinking increased the risk of persistent depressive symptoms (OR = 2.43; 95%CI = 1.05-5.06) among females. CONCLUSION Problem drinking may increase the risk of incident probable depression and anxiety among older females. Furthermore, problem drinking led to a higher likelihood of persistent depressive symptoms in older female participants. Interventions targeting problem drinking among older females may prevent the onset and persistence of depression in this population, while also decreasing the incidence of anxiety symptoms.

Abstract
SummaryThree to four percent of the world’s population has diabetes mellitus (DM), which leads to a markedly increased risk of blindness, renal failure, amputation and cardiovascular disease, and reduces average life expectancy by 10 or more years. However, the prevalence of this severe metabolic disease among patients with severe mental illness (SMI), including schizophrenia, bipolar disorder, schizoaffective disorder and major depressive disorder, is higher than in the general population and its impact on these individuals significantly greater. We reviewed the literature on what is currently known about the relationship between SMI and DM and report prevalence rates of DM type 2 as well as important individual lifestyle choices and side effects of antipsychotic and antidepressant treatment, which each account for much of the increased risk of this metabolic disease in these patients. However, the exact cause and effect relationships between the prescription of these medications and DM type 2 still remain to be elucidated.

Abstract
BACKGROUND Perceived stress may be a modifiable risk factor for mild cognitive impairment (MCI) and ultimately dementia, but studies on this topic from low- and middle-income countries (LMICs) are lacking. OBJECTIVE We assessed the association between perceived stress and MCI in six LMICs (China, Ghana, India, Mexico, Russia, and South Africa) using nationally representative data. METHODS Cross-sectional, community-based data on individuals aged ≥50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. A perceived stress score (range 0 [lowest stress] to 10 [highest stress]) was computed based on two questions from the Perceived Stress Scale. Multivariable logistic regression analysis was conducted to assess the as-sociation between perceived stress and MCI. RESULTS The mean (SD) age of the 32,715 participants was 62.1 (15.6) years and 51.7% were females. After adjustment for potential confounders including depression, in the overall sample, a one-unit increase in the perceived stress score was associated with a 1.14 (95% CI = 1.11-1.18) times higher odds for MCI. The association was similar among those aged 50-64 and ≥65 years. Countrywise analysis showed that there was a moderate level of between-country heterogeneity in this association (I2 = 59.4%), with the strongest association observed in Russia (OR = 1.33, 95% CI = 1.15-1.55). CONCLUSION If our study results are confirmed in prospective studies, addressing perceived stress may have an impact in reducing the risk for MCI and subsequent dementia in LMICs.

Abstract
BACKGROUND Suicide is a public health problem in Uganda among indigenous societies, and different societies manage its aftermath differently. AIM To explore how the Acholi in Northern Uganda manage the aftermath of suicide. METHODS We conducted a qualitative study in Gulu district, a post-conflict area in Northern Uganda. We conducted a total of four focus group discussions (FGDs) and 12 key informant (KI) interviews. KI interviews were conducted with community leaders, while the FGDs were conducted with members of the general population. We analysed the data by means of Grounded Theory. RESULTS Our findings indicate that rituals form a large part in managing suicide among the Acholi. Study communities practised distancing (symbolically and physically) as a way of dealing with the threat of suicide. CONCLUSION Distancing was organized into two broad themes: affect regulation and securing future generations. It is recommended that public health interventions should utilize cultural institutions in the prevention of suicide.

Abstract
BACKGROUND Exercise improves cardiorespiratory fitness (CRF) and reduces depressive symptoms in people with depression. It is unclear if changes in CRF are a predictor of the antidepressant effect of exercise in people with depression. AIMS To investigate whether an increase in CRF is a predictor of depression severity reduction after 12 weeks of exercise (trial registration: DRKS study ID, DRKS00008745). METHOD The present study includes participants who took part in vigorous (n = 33), moderate (n = 38) and light (n = 39) intensity exercise and had CRF information (as predicted maximal oxygen uptake, V̇O2max) collected before and after the intervention. Depression severity was measured with the Montgomery-Åsberg Depression Rating Scale (MADRS). V̇O2max (L/min) was assessed with the Åstrand-Rhyming submaximal cycle ergometry test. The main analysis was conducted pooling all exercise intensity groups together. RESULTS All exercise intensities improved V̇O2max in people with depression. Regardless of frequency and intensity of exercise, an increase in post-treatment V̇O2max was significantly associated with reduced depression severity at follow-up (B = -3.52, 95% CI -6.08 to -0.96); adjusting for intensity of exercise, age and body mass index made the association stronger (B = -3.89, 95% CI -6.53 to -1.26). Similarly, increased V̇O2max was associated with higher odds (odds ratio = 3.73, 95% CI 1.22-11.43) of exercise treatment response (≥50% reduction in MADRS score) at follow-up. CONCLUSIONS Our data suggest that improvements in V̇O2max predict a greater reduction in depression severity among individuals who were clinically depressed. This finding indicates that improvements in V̇O2max may be a marker for the underpinning biological pathways for the antidepressant effect of exercise. DECLARATION OF INTEREST None.

Abstract
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.

Abstract
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.

Abstract
Background Sedentary behavior (SB) is associated with adverse health outcomes independent of levels of physical activity. However, data on its correlates are scarce from low- and middle-income countries (LMICs). Thus, we assessed the correlates of SB in six LMICs (China, Ghana, India, Mexico, Russia, South Africa) using nationally representative data. Methods Cross-sectional, community-based data on 42,469 individuals aged ≥18 years from the World Health Organization’s Study on Global Ageing and Adult Health were analyzed. 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 high SB were estimated by multivariable logistic regression analyses. Results The overall prevalence (95%CI) of high SB was 8.3% (7.1–9.7%). In the overall sample, the most important sociodemographic correlates of high SB were unemployment and urban residence. Physical inactivity, morbid obesity (BMI≥30.0 kg/m2), higher number of chronic conditions, poor self-reported health, higher disability levels, and worse health status in terms of mobility, pain/discomfort, affect, sleep/energy and cognition were associated with high SB. Several between-country differences were found. Conclusion The current data provides important guidance for future interventions across LMICs to assist sedentary people to reduce their SB levels.

Abstract
BACKGROUND Depression is common and burdensome in adolescents. Understanding modifiable environmental risk factors is essential. There is evidence that physical activity is protective of depression. However, the impact of sedentary behavior (SB) on depression is relatively under-researched especially in low- and middle-income countries (LMICs). In this cross-sectional study, we explored the association between SB and depressive symptoms in adolescents from 30 LMICs, controlling for confounders including physical activity. METHOD Data from the Global school-based Student Health Survey were analyzed in 67,077 adolescents [mean (SD) age 13.8 (0.9) years; 50.6% girls). Self-report measures assessed depressive symptoms during the past 12 months, and SB, which was a composite variable assessing time spent sitting and watching television, playing computer games, talking with friends during a typical day excluding the hours spent sitting at school and doing homework. Multivariable logistic regression analysis was conducted and a countrywide meta-analysis undertaken. RESULTS The prevalence of depressive symptoms and ≥ 3 h/day of SB were 28.7 and 30.6%, respectively. There was a linear increase in the prevalence of depressive symptoms with increasing sedentary time beyond ≥3 h/day (vs. < 1 h/day). Among boys, 1-2 h/day of SB was associated with lower odds for depression (vs. < 1 h/day). Countrywide meta-analysis demonstrated that spending ≥3 h/day versus < 3 h/day was associated with a 20% increased odds for depressive symptoms (OR = 1.20; 95% CI = 1.16-1.24) with low between-country heterogeneity (I2 = 27.6%). CONCLUSION Our data indicate that being sedentary for ≥3 h/day is associated with increased odds for depressive symptoms in adolescence. Future longitudinal data are required to confirm/refute the findings to inform public interventions which aim to limit the time spent being sedentary in adolescents.

Sedentary behavior and perceived stress among adults aged ≥50 years in six low- and middle-income countries. Maturitas 2018; 116:100-107. [PMID: 30244769 DOI: 10.1016/j.maturitas.2018.08.005] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2018] [Revised: 07/09/2018] [Accepted: 08/04/2018] [Indexed: 01/09/2023]
Abstract
BACKGROUND Sedentary behavior and perceived stress are both negatively associated with physical and mental health. Little is known about the association between sedentary behavior and perceived stress, and there is a particular paucity of data on people aged ≥50 years from low- and middle-income countries (LMICs). METHODS We analyzed cross-sectional, community-based data from 34,129 individuals aged ≥50 years [mean age 62.4 (SD = 16.0) years, 52% females] from six LMICs. Perceived stress was assessed using the Perceived Stress Scale and time spent sedentary per day was self-reported. Multivariable linear regression analyses were conducted, adjusting for important socio-economic and physical and mental health-related confounders. RESULTS The mean perceived stress score increased with greater sedentary time (38.4 for 0-<4 h/day to 54.2 for ≥11 h/day). In the fully adjusted model, 4-8, 8-11, and ≥11 h/day of sedentary behavior (SB) were associated with 1.97 (95%CI = 0.57-3.36), 7.11 (95%CI = 4.96-9.27), and 9.02 (95%CI = 5.45-12.59) times higher mean perceived stress scores, compared with 0-<4 h/day. Greater time spent sedentary was associated with higher perceived stress scores in all six countries, although the association in Mexico fell short of statistical significance. CONCLUSION This is the first multinational analysis to show that a greater amount of sedentary behavior is associated with higher levels of perceived stress among older adults in LMICs. Future research may examine the types and contexts of sedentary behavior, and explore the underlying mechanisms of the relationship.

Abstract
BACKGROUND Smoking is a leading modifiable cause of global morbidity and mortality. Research from high-income countries has found a high prevalence of smoking among people with depression and suggested that this may partially contribute to the increased premature mortality in this population. Limited research has investigated smoking behaviors across the depression spectrum and in low- and middle-income countries (LMICs). This study explored the relationship between depression and smoking across 48 LMICs. METHODS We conducted a cross-sectional, community-based study comprising 242,952 people [mean age 38.4 (SD = 16.1) years, 50.8% females] from the World Health Survey. Multivariable binary logistic regression analyses were performed to investigate the relationship between depression (including subsyndromal, brief depressive episode and depressive episodes) and smoking behaviours. RESULTS Overall, the prevalence of current smoking was lowest in Africa (13.5%) and highest in Asia (32.2%). A depressive episode was present in 6.7% of the sample. Compared to people without depression, subsyndromal depression, brief depressive episode, and depressive episodes were all significantly associated with smoking with similar effect sizes (ORs: 1.36-1.49). Countrywide meta-analysis found that the pooled overall OR for smoking in depression was 1.42 (95%CI = 1.32-1.52, I2 = 39.7%). Furthermore, alcohol consumption and male gender were consistently associated with smoking across all regions and smoking was consistently less common in those who were wealthier and had a higher education. CONCLUSION These data suggest that the depression spectrum is consistently associated with high levels of smoking behaivours in LMICs. Given that most of the world's smokers reside in LMICs, future smoking cessation interventions are required to target people with depression.

Abstract
PURPOSE OF REVIEW The purpose of this paper was to provide a comprehensive narrative review of the relationship between physical activity (PA) and anxiety and the rationale for including it as a treatment option for anxiety disorders. Several gaps in the literature are highlighted alongside recommendations for future research. RECENT FINDINGS PA in the general population has established efficacy in preventing and managing cardiovascular disease and improving wellbeing. Recent epidemiological data further suggests that people who are more active may be less likely to have anxiety disorders. In addition, evidence from systematic reviews of randomised control trials suggests that exercise training, a subset of PA, can reduce symptoms in anxiety and stress-related disorders, such as post-traumatic stress disorder, agoraphobia and panic disorder. Anxiety disorders are common, burdensome and costly to individuals and wider society. In addition to the profound negative impact on individuals' wellbeing and functioning, they are associated with worsened physical health, including a higher risk for cardiovascular diseases and premature mortality. Although pharmacotherapy and psychological interventions are helpful for many, these treatment approaches are not effective for everyone and are insufficient to address common physical health complications, such as the elevated risk of cardiovascular disease. Given the combined anxiolytic and physical health benefits of increased activity, PA presents a promising additional treatment option for people with anxiety disorders. However, there remain key gaps in the literature regarding the mechanisms underlying the effects of PA, optimal PA protocols, methods of improving adherence and the importance of physical fitness. These must be addressed for PA to be successfully implemented in mental health services.

Abstract
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.

Abstract
OBJECTIVE Pain and sleep disturbances are widespread, and are an important cause of a reduced quality of life. Despite this, there is a paucity of multinational population data assessing the association between pain and sleep problems, particularly among low- and middle-income countries (LMICs). Therefore, we investigated the relationship between pain and severe sleep disturbance across 45 LMICs. METHOD Community-based data on 240,820 people recruited via the World Health Survey were analyzed. Multivariable logistic regression analyses adjusted for multiple confounders were performed to quantify the association between pain and severe sleep problems in the last 30 days. A mediation analysis was conducted to explore potential mediators of the relationship between pain and severe sleep disturbance. RESULTS The prevalence of mild, moderate, severe, and extreme levels of pain was 26.0%, 16.2%, 9.1%, and 2.2% respectively, whilst 7.8% of adults had severe sleep problems. Compared to those with no pain, the odds ratio (OR, 95% CI) for severe sleep problems was 3.65 (3.24-4.11), 9.35 (8.19-10.67) and 16.84 (13.91-20.39) for those with moderate, severe and extreme pain levels respectively. A country wide meta-analysis adjusted for age and sex demonstrated a significant increased OR across all 45 countries. Anxiety, depression and stress sensitivity explained 12.9%, 3.6%, and 5.2%, respectively, of the relationship between pain and severe sleep disturbances. CONCLUSION Pain and sleep problems are highly co-morbid across LMICs. Future research is required to better understand this relationship. Moreover, future interventions are required to prevent and manage the pain and sleep disturbance comorbidity.

Abstract
OBJECTIVE The authors examined the prospective relationship between physical activity and incident depression and explored potential moderators. METHOD Prospective cohort studies evaluating incident depression were searched from database inception through Oct. 18, 2017, on PubMed, PsycINFO, Embase, and SPORTDiscus. Demographic and clinical data, data on physical activity and depression assessments, and odds ratios, relative risks, and hazard ratios with 95% confidence intervals were extracted. Random-effects meta-analyses were conducted, and the potential sources of heterogeneity were explored. Methodological quality was assessed using the Newcastle-Ottawa Scale. RESULTS A total of 49 unique prospective studies (N=266,939; median proportion of males across studies, 47%) were followed up for 1,837,794 person-years. Compared with people with low levels of physical activity, those with high levels had lower odds of developing depression (adjusted odds ratio=0.83, 95% CI=0.79, 0.88; I2=0.00). Furthermore, physical activity had a protective effect against the emergence of depression in youths (adjusted odds ratio=0.90, 95% CI=0.83, 0.98), in adults (adjusted odds ratio=0.78, 95% CI=0.70, 0.87), and in elderly persons (adjusted odds ratio=0.79, 95% CI=0.72, 0.86). Protective effects against depression were found across geographical regions, with adjusted odds ratios ranging from 0.65 to 0.84 in Asia, Europe, North America, and Oceania, and against increased incidence of positive screen for depressive symptoms (adjusted odds ratio=0.84, 95% CI=0.79, 0.89) or major depression diagnosis (adjusted odds ratio=0.86, 95% CI=0.75, 0.98). No moderators were identified. Results were consistent for unadjusted odds ratios and for adjusted and unadjusted relative risks/hazard ratios. Overall study quality was moderate to high (Newcastle-Ottawa Scale score, 6.3). Although significant publication bias was found, adjusting for this did not change the magnitude of the associations. CONCLUSIONS Available evidence supports the notion that physical activity can confer protection against the emergence of depression regardless of age and geographical region.

Abstract
Abstract
Aim: Cancer and cancer treatment-related cognitive impairments are frequently reported in cancer survivors, presenting as lack of attention, impaired executive function and short-term money loss. The aetiology of these impairments is largely unknown. Recently, serum level of brain-derived neurotrophic factor (BDNF) has been associated with cancer related cognitive impairments. BDNF is a neurotrophin, secreted in responses to muscle contraction. Meanwhile, muscle dysfunction, characterized by muscle strength and muscle composition, is common in cancer survivors. Yet its impact on cancer survivors' cognitive function is unknown. To address this gap we evaluated for the first time the associations of muscle strength determined by handgrip with two cognitive function outcomes in cancer survivors using data from the National Health and Nutrition Examination Survey (NHANES). Method: Data in two waves of NHANES (2011-2014) were aggregated. Handgrip strength in kilogram (kg) was measured with the Takei Digital Grip Strength Dynamometer, defined as the maximum value achieved using either hand. Data on two cognitive function tests were extracted, both were conducted among adults 60 years and older: the Animal Fluency Test (AFT) which examines categorical verbal fluency (a component of executive function), and the Digital Symbol Substitution test (DSST) which assesses processing speed, sustained attention and working memory. Survey analysis procedures were used to account for the complex sampling design of the NHANES. Gender-specific multivariable linear regression models were used to estimate associations of handgrip strength with cognitive test scores, adjusting for confounders (age, gender, race/ethnicity, education, marital status, smoking status, depression and leisure time physical activity). For explorative purpose, we further adjusted for handgrip strength squared. Results: There were 383 cancer survivors (mean age=70.9 years, mean BMI=29.3 kg/m2) with detailed data for analyses. Prevalent cancer types were breast (22.9%), prostate (16.4%), colon (6.9%) and cervix (6.2%). The prevalence of handgrip strength defined sarcopenia was 10.9% in men (<30kg) and 20.4 % in women (<20kg). Scores on AFT and DSST were 18.0 (s.e. 0.4) and 51.7 (s.e. 1.0), respectively. We observed significant linear associations of handgrip strength with both test scores in women. Each increase kg of handgrip strength was associated with 0.20 (95% CI: 0.08 to 0.33) higher score on AFT and 0.83 (95% CI: 0.30 to 1.35) higher score on DSST. In men, we observed inverted U-shape association between handgrip strength and DSST score, which peaked at handgrip strength of 40-42 kg. Conclusion: Handgrip determined muscle strength appears to be associated with aspects of cognitive functions in cancer survivors. Prospective studies are needed to identify the role of muscle on cancer related-cognitive impairments in men and women cancer survivors.
