Psychosocial Mediators of the Fitness-Depression Relationship Within Adolescents

Abstract

A lot of evidence showed that boys and girls are at high risk of developing major or minor depression in adolescence. Increases in physical fitness have been associated with lower levels of depressive symptoms, yet the mechanisms that underlie (or mediate) this relationship have not been thoroughly examined. 528 boys (mean age = 12.33 years) and 507 girls (mean age = 12.32 years) drawn from a suburban school district participated. Self-report measures were used to assess the mediators (body satisfaction and social physique anxiety) and the outcome (depression); the Progressive Aerobic Cardiovascular Endurance Run (PACER) in conjunction with age, Body Mass Index (BMI), and sex were used to determine an objective estimate of cardiorespiratory fitness. Path analyses were used to test the proposed models. The effects of fitness on depressive symptoms were mediated through body satisfaction and social physique anxiety; 25% to 35% of the depression variance was explained. Boys' and girls' depression scores were based on the extent that their fitness levels improved their body satisfaction and lowered their social physique anxiety; body satisfaction was particularly important for girls. Thus, early adolescents' psychological well-bein...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
