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...

Poor health outcomes associated with posttraumatic stress disorder (PTSD) may reflect engagement in unhealthy behaviors that increase morbidity risk and disengagement in healthy behaviors that decrease morbidity risk. Although research supports this pattern, findings are not definitive, particularly for healthy behaviors. Many studies have not controlled for effects of concurrent generalized anxiety and depression, which might explain conflicting findings. To address this limitation, we used an online cross-sectional research design and multivariate multilevel modelling to evaluate associations between a multitude of health behaviors (i...

BACKGROUND: Television (TV) viewing and computer use have been associated with higher risk of depression, but studies specifically assessing the impact of these and other types of sedentary behaviors (SBs) on the mental health of older adults are scarce and their results are inconclusive. Similarly, the association between specific types of recreational physical activity (rPA) and mental health in older adults is poorly understood. METHODS: In 2012, information on SBs, rPA, and other health behaviors was collected with validated questionnaires from community-dwelling older adults participating in the Seniors-ENRICA cohort...

OBJECTIVE: To experimentally examine whether increasing sedentary behavior, among a young adult active population, for one week is still associated with increased depression and anxiety symptomology even when allowing for a moderate engagement in physical activity (PA). METHODS: Participants were confirmed as active via self-report and accelerometry during baseline and randomly assigned to one of three experimental groups. The No Exercise Group (n = 19) was instructed to reduce steps to less than 5000/day and were not allowed to exercise for one-week; the Reduced MVPA (moderate-to-vigorous PA) Group (n = 18) was instructed to reduce steps to less than 5000/day but exercised for 50% of their previously reported vigorous PA for one-week; and the Control Group (n = 20) maintained normal activity for one-week...

Low physical activity (PA), high sedentary behavior (SB), and overweight and obesity have been shown to associate with increased Type 2 diabetes risk among adolescents. We investigated PA, SB, and overweight and obesity among Youth Risk Behavior Survey (YRBS) respondents to determine if non-heterosexual youth may be at increased diabetes risk compared to heterosexual youth. Weighted city and state YRBS data were pooled across 44 jurisdictions biennially from 2009-2015, resulting in a sample size of 350,673 students...

Characteristics of the physical childcare environment are associated with children’s sedentary behavior (SB) and physical activity (PA) levels. This study examines whether these associations are moderated by child characteristics. A total of 152 1- to 3-year-old children from 22 Dutch childcare centers participated in the study. Trained research assistants observed the physical childcare environment, using the Environment and Policy Assessment Observation (EPAO) protocol. Child characteristics (age, gender, temperament and weight status) were assessed using parental questionnaires...

PURPOSE: Physical inactivity and sedentary behavior (SB) are independent risk factors for cardiovascular disease and all-cause mortality. No studies appear to have investigated whether SB in cardiac rehabilitation (CR) participants changes over time. The aim of this study was to objectively assess physical activity (PA) and SB of CR participants over 6 wks. METHODS: Using a prospective cohort study design, 72 CR participants, age = 64.2 ± 9.6 y (mean ± standard deviation [SD]) (79% male), wore an ActiGraph ActiSleep accelerometer for 7 consecutive days at the beginning and end of a 6-wk program to assess daily minutes of moderate-to-vigorous PA (MVPA) and SB (<100 counts/min)...

Stress and depressive symptoms are associated with maladaptive health behavior practices such as unhealthy eating, sedentary behavior, insufficient sleep, and substance use. The relative and interactive effects of stress and depressive symptoms on health behavior practices are less well understood. The present study examined these processes in a daily diary study of 127 college students. Results from hierarchical generalized linear models indicated that depressive symptoms, and chronic and daily stress, but not acute stressful life events, were significantly associated with a composite score of daily maladaptive health behavior engagement (depressive symptoms b = ...

Elucidating mechanisms by which physical exercise promotes resilience, the brain's ability to cope with prolonged stress exposure while maintaining normal psychological functioning, is a major research challenge given the high prevalence of stress-related mental disorders, including major depressive disorder. Chronic voluntary wheel running (VWR), a rodent model that mimics aspects of human physical exercise, induces the transcription factor ΔFosB in the nucleus accumbens (NAc), a key reward-related brain area...

Introduction: Risk behaviors commonly co-occur, typically emerge in adolescence, and become entrenched by adulthood. This study investigated the clustering of established (physical inactivity, diet, smoking, and alcohol use) and emerging (sedentary behavior and sleep) chronic disease risk factors among young Australian adults, and examined how clusters relate to mental health. Methods: The sample was derived from the long-term follow-up of a cohort of Australians...

This study was designed to examine whether treadmill exercise would attenuate the severity of physical dependence, methadone-induced anxiety, depression and voluntary morphine consumption in morphine withdrawn rats receiving methadone maintenance treatment (MMT). The rats were chronically treated with bi-daily doses (10 mg/kg, at 12 h intervals) of morphine for 14 days. The exercising rats receiving MMT were forced to run on a motorized treadmill for 30 days during morphine withdrawal. Then, rats were tested for the severity of morphine dependence, the elevated plus-maze (EPM), sucrose preference test (SPT) and voluntary morphine consumption using a two-bottle choice (TBC) paradigm...

BACKGROUND: In light of on-going policy changes related to cannabis use in the United States, it is important to examine possible associations between cannabis use and subsequent behaviors of public health interest. This study identified prospective associations between cannabis use during first-year post high-school and a wide range of positive and negative health and social measures one year later. METHODS: Data were from Waves 4 (Time 1; 1st year after high-school) and 5 (Time 2; one year later) of the NEXT Generation Health Study, a national sample of emerging adults in the United States (n = 1915; mean age = 20...

This study examined the effects of 12 weeks North-American ginseng supplementation, exercise training, and sedentary behavior on vascular responses in type I diabetic rats. The following hypotheses were tested: (1) ginseng supplementation would result in improved vascular responsiveness and sensitivity; (2) exercise training would result in further improvement in these vascular responses; (3) control rats with no access to exercise would show a depressed vascular response compared to control rats that were not exposed to a sedentary lifestyle...

Although there is good evidence that sedentary behavior is associated with poor health outcomes in healthy persons and patients with cardiovascular disease, the mental health consequences of sedentary behavior have not been widely studied. In this report, we conducted a cross-sectional analysis to examine the relation of self-reported sedentary behavior and depression in a sample of 4,043 hospitalized men and women with acute coronary syndrome enrolled in a randomized clinical trial in rural China. Sedentary behavior was assessed by self-report, and depression was assessed with the Patient Health Questionnaire-9 (PHQ-9); a subset of 1,209 patients also completed the Beck Depression Inventory-II...

OBJECTIVE: Few studies have explored the potential interrelated associations of screen time and physical activity with mental health in youth, particularly using objective methods. We examined cross-sectional associations of these variables among Icelandic adolescents, using objective and subjective measurements of physical activity. METHODS: Data were collected in the spring of 2015 from 315 tenth grade students (mean age 15.8 years) in six elementary schools in metropolitan Reykjavík, Iceland...

Evidence for a critical pathophysiological role of aberrant cytoskeletal dynamics is being uncovered in a growing number of neuropsychiatric syndromes. A sedentary lifestyle as well as overt psychopathology is prevalent in patients with the metabolic syndrome. Using mice deficient in gelsolin (Gsn-/- ), a crucial actin-severing protein, we here investigated reduced actin turnover as a potential common driver of metabolic disturbances, sedentary behavior, and an anxious/depressive phenotype. Gelsolin deficiency resulted in reduced lifespan...

BACKGROUND: Puerto Rico is experiencing an economic and healthcare crisis, yet there are scarce recent and comprehensive reports on the population's health profile. We aimed to describe prevalent risk factors and health conditions of adults living in Puerto Rico and assess their interrelationship. METHODS: Participants (n = 380) aged 30-75y recruited from a 2015 convenience sample in primary care clinics in the San Juan, Puerto Rico metropolitan area answered cross-sectional interviewer-administered questionnaires on sociodemographic characteristics, lifestyle behaviors, self-reported medically-diagnosed diseases, health services, and psychosocial factors...

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...
