and older say their favorite type of exercise is walking ( Stathokostas & Jones, 2016 ). For these reasons, increased walking has been identified as the most likely way that older adults can achieve healthy levels of physical activity ( Niven & Markland, 2016 ). Depressive symptoms are defined as

The purpose of this study was to examine whether college students meeting the vigorous physical activity (VPA) recommendation reported less frequent symptoms of depression than those not meeting the recommendation.
A secondary analysis of the Utah Higher Education Health Behavior Survey was conducted. Descriptive statistics and unconditional logistic regressions were calculated.
The final sample included 8621 participants (age = 21.34 ± 2.6 years). There was a difference in the frequency of depressive symptoms and VPA. Those not meeting the VPA recommendation reported having more frequent depressive symptoms than those meeting the VPA recommendation. Results were consistent by gender.
In this sample, our data suggest VPA may be associated with a reduction in depressive symptoms. These findings might be indicative of a dose–response relationship between VPA and symptoms of depression in college students.

This study examined cross-sectional and longitudinal associations between physical activity, sedentary behavior, and depressive symptoms among adolescents.
Participants were 155 adolescents (14.4 years ± 0.61) in 2004 (40% boys). Data collection occurred in 2004 and again in 2006. At both time points, participants completed the Centers for Epidemiological Studies Depression Scale for Children (CES-DC), from which they were classified as having depressive symptoms (≥15) or not (<15). Organized sport and TV viewing were self-reported and moderate-to-vigorous (MVPA) and vigorous (VPA) physical activity and sedentary time were objectively measured. Logistic and linear regression analyses examined cross-sectional and longitudinal associations between MVPA, VPA, organized sport, TV viewing, sedentary time, and symptoms of depression.
There were no cross-sectional or longitudinal associations between MVPA, VPA, organized sport, sedentary time, and symptoms of depression among boys or girls. However, having symptoms of depression in 2004 did predict higher TV viewing among adolescent girls in 2006 (approximately 168 minutes/week more TV viewing; P ≤ .001).
MVPA, VPA, organized sport and objectively-measured sedentary time appeared unrelated to depressive symptoms in this sample, but depressive symptoms predicted increased TV viewing over time among adolescent girls. Further research is required to determine the clinical relevance of this finding.

While research has confirmed a negative relationship between adult depression and physical activity, there is little evidence for children. This study examined the relationship of being classified as physically active or inactive by a parent or a teacher to depressive symptoms in children 8 to 12 years of age (N = 933). It also assessed the relationship of playing sports outside of school, and of meeting health related fitness standards, to symptoms of depression. Relative risk of depressive symptoms for inactive classification was 2.8 to 3.4 times higher than it was for active, 1.3 to 2.4 times higher for children not playing sports outside of school, and 1.5 to 4.0 times higher for those not meeting health related fitness goals.

This study employed ordinal logistic regression analyses to investigate the relationship between American adolescents’ participation in physical activity and depressive symptomatology. Data were drawn from the second Child Development Supplement to the Panel Study of Income Dynamics (CDS II), which was conducted over 2002-2003. Fewer than 60% of adolescents were found to accumulate 60 min of moderate-to-vigorous physical activity (MVPA) outside of school hours on week or weekend days. Accumulated duration of MVPA was not, however, significantly associated with severity of depressive symptoms for either gender. Males who were not involved in sporting clubs or lessons were more likely than males who were highly involved to experience greater severity of depressive symptoms (OR = 3.24, CI = 1.33, 7.87). Results highlight gender variability in the psychosocial correlates of sporting participation and prompt further investigation of the relevance of current physical activity guidelines for mental health in adolescence.

Although physical activity (PA) has been demonstrated to reduce symptoms of depression and anxiety, research on the mental health benefits of PA in older adults is limited. Moreover, the psychosocial factors that might mediate or moderate the relationship between PA and depression in this population are largely unexplored.
Using a sample of adults age 65 and older (N = 2736), we examined whether the major components of the stress process model (stress, social support, mastery, self-esteem) and physical health mediate or moderate the relationship between PA and depressive symptoms.
Physical health has the single largest effect, accounting for 45% of the effect of PA on depression. The stress process model, with physical health included, accounts for 70% of the relationship between PA and depression.
Among older adults with above average levels of perceived mastery, greater physical activity is associated with higher levels of depression. Limitations and directions for further research are discussed.

Depression among elite athletes is a topic of increasing interest, but empirical data are rare. The present study aimed to provide insight into the prevalence of depressive symptoms among German elite athletes and possible associated factors. In an online survey of 162 athletes, we explored depressive symptoms, chronic stress, coping strategies and stress-recovery states. Results indicated an overall prevalence of 15% for depression among elite athletes (n = 99), and revealed higher levels of depressive symptoms among the individual athletes than the team athletes. Furthermore, correlation analyses showed a significant connection between high levels of depressive symptoms and high levels of chronic stress, negative coping strategies and negative stress-recovery states. Results indicate that the prevalence for depressive symptoms in elite athletes is comparable to that in the general German population. Moreover, exploratory analyses provide first indications of factors associated with depressive symptoms.

The study aims to understand the possible gender difference in the associations between physical activity and depressive symptoms during pubertal transition.
Participants were 30,399 children and adolescents of Han ethnicity from urban and rural areas in 8 cities in China. Physical activity (PA) and depressive symptom was assessed by adapted Youth Risk Behavior Survey and Children Depression Inventory (CDI), respectively. Pubertal development was assessed by trained physicians.
In China, over 30% boys and 40% girls reported having no vigorous PA (VPA) or moderate PA (MPA) in the past week. In girls, participating in VPA 1 to 2 days/week showed protective effect for depressive symptoms; whereas in boys, participating in MPA 1 to 2 days/week showed protective effect for depressive symptoms at and after genital stage III (G3).
Moderate frequency (1 to 2 days/week) in PA undertaken might be encouraged to prevent depressive symptoms among adolescents.

The purpose of this study was to examine the longitudinal relationships between naturally occurring changes in leisure-time physical activity, depressive symptoms and self-efficacy in adolescent girls. We also aimed to test whether depressive symptoms would moderate the self-efficacy-physical activity relationship. Participants were 181 urban adolescent girls. Physical activity was measured using the 3-Day Physical Activity Recall. Self-efficacy and depressive symptoms were assessed using questionnaires. Body height and body mass were measured and body mass index (BMI) was calculated. Data were collected on three occasions over a 2-year period. There was a decrease in physical activity and self-efficacy and increase in depressive symptoms across three measurement occasions. There were statistically significant and negative relationships between initial level and change for physical activity and depressive symptoms. Initially higher levels of physical activity were related with initially lower levels of depressive symptoms, and change in physical activity across time was inversely associated with change in levels of depressive symptoms across measurements. There were statistically significant and positive relationships between initial level and change for physical activity and self-efficacy after controlling effect of BMI. Latent growth modeling (LGM) also indicated a moderating effect of depressive symptoms on the self-efficacy-physical activity relationship. Girls who had high initial levels of self-efficacy and smaller increases in depressive symptoms had the lowest decline in physical activity participation. Our results encourage the design of interventions that reduce depressive symptoms and increase self-efficacy as a possible of means of increasing adolescent girls’ physical activity.
