A Scoping Review on College Student Physical Activity: How Do Researchers Measure Activity and Examine Inequities?

BACKGROUND: The purpose of this scoping review was to critically examine the design and quality of contemporary research involving college student physical activity participation, focusing on physical activity measurement, assessment of sociodemographic characteristics, and examination of inequities based on sociodemographic characteristics. METHODS: Systematic searches were conducted in 4 electronic databases. RESULTS: From 28,951 sources screened, data were extracted from 488 that met the inclusion criteria. The majority of the studies were cross-sectional in design (91.4%) and employed convenience sampling methods (83.0%). Based on the subsample of studies that reported the percentage of students meeting aerobic (n = 158; equivalent of 150 min/wk of moderate physical activity) and muscle-strengthening activity recommendations (n = 8; ≥2 times/wk), 58.7% and 47.8% of students met aerobic and muscle-strengthening recommendations, respectively. With the exception of age and sex, sociodemographic characteristics were rarely assessed, and inequities based upon them were even more scarcely examined-with no apparent increase in reporting over the past decade. CONCLUSIONS: College student physical activity levels remain concerningly low. The generalizability of findings from the contemporary literature is limited due to study design, and acknowledgement of the influence that sociodemographic characteristics have on physical activity has largely been overlooked. Recommendations for future research directions and practices are provided.

Growing into "Us": Trajectories of Social Identification with College Sport Teams Predict Subjective Well-Being.

BACKGROUND: Groups are often a source of social identification that may elicit subjective well-being. When joining and maintaining membership of groups such as sport clubs, it is anticipated that members will experience varying trajectories of identification strength, but it is unclear how these trajectories may relate to well-being. METHOD: Participants were 697 college students (64% female), nested within 35 club-level sport teams. The current study longitudinally assessed students' social identification with sport teams at three timepoints (3-month lags) across a school year to examine the extent that growth trajectories in identification strength predicted indices of well-being (i.e. life satisfaction, happiness, and subjective health) at the end of the school year. RESULTS: Multilevel latent growth modeling revealed that end-of-year well-being was positively predicted by social identification intercepts (b = .24, p = .010) and growth trajectories (b = .75, p < .001). Accounting for baseline identification, steeper increases in social identification (upward trajectories) predicted greater well-being. CONCLUSIONS: Findings support established theory that social identification relates to well-being, while adding novel insights that students may experience unique benefits when their social identity strengthens over the course of a school year. Considering recent declines in college student well-being, groups like sport teams represent a source for social identification that should be fostered throughout the course of one's group membership.

Adolescent Sport Participation and Symptoms of Anxiety and Depression: A Systematic Review and Meta-Analysis.

Sport may protect against symptoms of mental disorders that are increasingly prevalent among adolescents. This systematic review explores the relationship between adolescent organized sport participation and self-reported symptoms of anxiety and depression. From 9,955 records screened, 29 unique articles were selected that included 61 effect sizes and 122,056 participants. Effects were clustered into four categories based on the operationalization of sport involvement: absence or presence of involvement, frequency of involvement, volume of involvement, and duration of participation. Results from the random-effects meta-analyses indicated that symptoms of anxiety and depression were significantly lower among sport-involved adolescents than in those not involved in sport, although this effect size was small in magnitude. Meta-regression was used to identify how age and sex explained heterogeneity in effects. Although these results do not signify a causal effect, they do support theorizing that sport participation during adolescence may be a protective environment against anxiety and depressive symptoms.
