Sport-related concussions (SRCs) are prevalent in high school (HS) sports, though the determinants of, and relationships between concussion symptoms in this population remain relatively unknown. We analysed SRC data captured within the HS RIO injury surveillance system during 2014/15-2018/19. We used Generalized Estimating Equations to simultaneously assess covariate predictors of symptom presentations and identify pairwise symptom associations and employed multivariable ordinal logistic regressions to determine symptom resolution time (SRT) predictors. Among the 8,969 concussions assessed, headaches (94.3%) and dizziness (73.3%) were the most prevalently reported symptoms. In 5,953 boys' concussion assessed, class year, event type and injury mechanism emerged as determinants of various concussion symptoms, while in 3,016 girls' concussions assessed, class year, event type, injury mechanism, and sport type emerged as significant symptom determinants. In both groups, difficulty concentrating, sensitivity to light, sensitivity to noise, and disorientation were symptoms with the strongest associations with other symptoms. Odds of longer SRT were higher with greater endorsement (i.e. counts) of the subset of symptoms with strongest cross-domain associations (ORadj. = 1.35; 95% CI = [1.30, 1.40]). Our findings provide valuable information for informing sideline and follow-up clinical concussion assessment algorithms in high school athletes. [ABSTRACT FROM AUTHOR]

ObjectiveSedentary behaviors related to television (TV) viewing are associated with adiposity; however, few investigations have focused on South Asians, an ethnicity particularly vulnerable to metabolic perturbations. This study examined the relationships between TV viewing and adiposity in a cohort of middle-aged and older South Asians.MethodData were obtained from Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (N = 906; mean age [standard deviation] = 55 [9.4] years, 46% women). TV viewing hours per week was assessed through questionnaire and classified into tertiles for analysis. Multivariate linear regression models were used to examine the associations between TV viewing and measures of adiposity and body composition including body mass index (BMI), waist circumference, pericardial fat volume, and visceral, subcutaneous, and inter-muscular fat area after adjusting for covariates including intentional exercise.ResultsParticipants who were women, older, with lower education levels, and living longer in the United States watched TV for longer periods of times. Duration of TV viewing was positively associated with BMI (p

Background: Public health measures to contain the COVID-19 pandemic have led to disruptions in daily life, such as job loss and changes in activity. The present study examines the relationship between pandemic-related life events and disuse (prolonged sitting coupled with inactivity) among adults. Methods: A cross-sectional study of 4084 adults in Israel (September 2020). The primary independent variables were pandemic-related life events, such as job loss. The primary dependent variable was disuse as measured by the Rapid Assessment Disuse Index (RADI). The RADI was examined continuously and dichotomously as a low RADI score (<26: yes/no). Results: Linear regression indicated that experiencing a major life event during the pandemic was associated with lower RADI scores (−1.04; 95% confidence interval, −1.48 to −0.61). Similarly, logistic regression revealed that those experiencing a major life event had 1.18 (95% confidence interval, 1.03 to 1.34) times greater odds for low RADI scores in comparison to those not experiencing an event. Conclusions: Experiencing pandemic-related major life events was linked to less sitting time and increased activity levels among Israeli adults. Future research should examine underlying mechanisms explaining this relationship to facilitate the design and implementation of targeted interventions. [ABSTRACT FROM AUTHOR]

Background This study examines the relationship between various domains of sedentary behavior and subsequent cognitive function to evaluate whether different sedentary activities have specific associations with future cognitive performance. Methods Data were from 1 261 older adults participating in the Health, Aging, and Body Composition (Health ABC) Study between 1999/2000 and 2006/2007. Total sitting time (hours/day), reading time (hours/week), and TV time (≤27/≥28 h/wk) were self-reported at baseline and 3 years later. At follow-up, cognitive function was evaluated using the Teng Mini-Mental State Examination (3MS) and the Digit Symbol Substitution Test (DSST). Multivariable linear regression modeling examined the independent associations of baseline sedentary behaviors and 3-year change in those behaviors with cognitive function scores at follow-up, adjusting for important covariables. Results Baseline total sitting time was positively associated with 3MS (β = 0.14 ± 0.07; p <.05) and DSST (β = 0.20 ± 0.10; p <.05) scores at follow-up, as was reading time (β = 0.09 ± 0.03; p <.05 for 3MS score and β = 0.14 ± 0.04; p < 0.01 for DSST score). Participants who increased their TV watching time over 3 years had a significantly lower 3MS score (β = −1.45 ± 0.71; p <.05) at follow-up, compared with those who maintained a low level of TV time (referent). These findings were independent of age, sex, race, education level, health status, depressive symptoms, and physical activity. Conclusion Some types of sedentary behavior may have benefits for cognitive function in older age, thus highlighting the importance of measuring different domains of sitting time.

Background: Crucial evidence gaps regarding: (1) the joint association of physical activity and sedentary time with health outcomes and (2) the benefits of light-intensity physical activity were identified during the development of recommendations for the World Health Organization Guidelines on physical activity and sedentary behavior (SB). The authors present alternative ways to evidence the relationship between health outcomes and time spent in physical activity and SB and examine how this could be translated into a combined recommendation in future guidelines. Methods: We used compositional data analysis to quantify the dose–response associations between the balance of time spent in physical activity and SB with all-cause mortality. The authors applied this approach using 2005–2006 National Health and Nutrition Examination Survey accelerometer data. Results: Different combinations of time spent in moderate- to vigorous-intensity physical activity, light-intensity physical activity, and SB are associated with similar all-cause mortality risk level. A balance of more than 2.5 minutes of moderate- to vigorous-intensity physical activity per hour of daily sedentary time is associated with the same magnitude of risk reduction for all-cause mortality as obtained by being physically active according to the current recommendations. Conclusion: This method could be applied to provide evidence for more flexible recommendations in the future with options to act on different behaviors depending on individuals' circumstances and capacity.

Background: The Rapid Assessment Disuse Index (RADI) is a brief tool aimed to promptly assess primary care patients' overall physical inactivity and sedentary behavior. This study examines the relation between physical inactivity and sitting time (RADI) to cardiometabolic risk among primary care patients. Methods: Survey data and electronic medical record information were collated to explore the association between RADI scores (cumulative and sitting) to metabolic syndrome (and components) among women and men, using multivariable logistic regression. Results: Among women, the cumulative RADI score was not significantly associated with metabolic syndrome. However, the RADI sitting score was related to low high-density lipoprotein cholesterol and metabolic syndrome. That is, a transition to a higher RADI sitting score by 1 unit (vs remaining in the score) was related with a 1.4 and 1.3 times higher odds for having low high-density lipoprotein cholesterol (95% confidence interval, 1.05-1.87) and metabolic syndrome (95% confidence interval, 1.02-1.64), respectively. Among men, no significant relations were found. Conclusions: The RADI sitting score is positively and significantly related to high-density lipoprotein and metabolic syndrome among women, yet not men. Due to the RADI's potential clinical utility, future research should attempt to examine these relations in larger, more robust samples and adjudicated outcomes using a prospective design.
