Introduction. This study evaluated whether stages of change for physical activity (PA) predict sign-up, participation, and completion in a PA competition. Method. Deidentified data were provided to evaluate a PA competition between 16 different institutions from a public university system. Employees who completed a health assessment (HA) prior to the start of the PA competition ( n = 6,333) were included in the study. Participants completed a self-report HA and logged their PA throughout the competition. Multivariable logistic regression models tested whether stages of change predicted PA competition sign-up and completion. An ordinal logistic regression model tested whether stages of change predicted number of weeks of PA competition participation. Results. Stages of change predicted PA competition sign-up and completion, but not weeks of participation. The odds for PA competition sign-up were 1.64 and 1.98 times higher for employees in preparation and action/maintenance (respectively) compared with employees in precontemplation/contemplation. The odds for PA competition completion were 4.17 times higher for employees in action/maintenance compared with employees in precontemplation/contemplation/preparation. Conclusion. The PA competition was more likely to reach employees in preparation, action, or maintenance stages than precontemplation/contemplation. Most of the completers were likely participating in regular PA prior to the competition.

This study shows how simple and multiple logistic regression can be used in observational methodology and more specifically, in the fields of physical activity and sport. We demonstrate this in a study designed to determine whether three-a-side futsal or five-a-side futsal is more suited to the needs and potential of children aged 6-to-8 years. We constructed a multiple logistic regression model to analyze use of space (depth of play) and three simple logistic regression models to determine which game format is more likely to potentiate effective technical and tactical performance.

Adverse Childhood

Retrospective studies using adult self-report data have demonstrated that adverse childhood experiences (ACEs) increase risk of violence perpetration and victimization. However, research examining the associations between adolescent reports of ACE and school violence involvement is sparse. The present study examines the relationship between adolescent reported ACE and multiple types of on-campus violence (bringing a weapon to campus, being threatened with a weapon, bullying, fighting, vandalism) for boys and girls as well as the risk of membership in victim, perpetrator, and victim–perpetrator groups. The analytic sample was comprised of ninth graders who participated in the 2013 Minnesota Student Survey ( n ~ 37,000). Multinomial logistic regression models calculated the risk of membership for victim only, perpetrator only, and victim–perpetrator subgroups, relative to no violence involvement, for students with ACE as compared with those with no ACE. Separate logistic regression models assessed the association between cumulative ACE and school-based violence, adjusting for age, ethnicity, family structure, poverty status, internalizing symptoms, and school district size. Nearly 30% of students were exposed to at least one ACE. Students with ACE represent 19% of no violence, 38% of victim only, 40% of perpetrator only, and 63% of victim–perpetrator groups. There was a strong, graded relationship between ACE and the probability of school-based victimization: physical bullying for boys but not girls, being threatened with a weapon, and theft or property destruction ( ps < .001) and perpetration: bullying and bringing a weapon to campus ( ps < .001), with boys especially vulnerable to the negative effects of cumulative ACE. We recommend that schools systematically screen for ACE, particularly among younger adolescents involved in victimization and perpetration, and develop the infrastructure to increase access to trauma-informed intervention services. Future research priorities and implications are discussed.

A high proportion of individuals with disabilities remain physically inactive. Therefore, this study (web-based survey) investigated the relationships between the Transtheoretical Model (TTM) and physical activity among 224 adults with physical disabilities (M age = 45.4 years, SD = 10.78, females = 71%). Additionally, the most important TTM predictors of the stages of change and physical activity were examined. Standardized self-report scales of the TTM constructs and physical activity were completed. The study findings supported the theorized relationships between the TTM constructs and physical activity. The behavioral and cognitive processes of change distinguished the stages of change. These two constructs and self-efficacy mostly predicted physical activity (R2total = .18). The assessment methodology of the TTM constructs needs to be revisited.

<p><strong>INTRODUCTION: </strong>The present study was aimed to determine the prevalence and risk factors of GSD among a sample of general population in Karachi, South Pakistan.</p><p><strong>METHODOLOGY: </strong>A multistage random sampling method was employed on 30 clusters, where 60 subjects of age&gt;=25 years were randomly recruited from the study population from June 2013 till March 2015. Finally, data was analyzed and logistic regression models were used to find the correlation between selected variables and gallstone disease.</p><p><strong>RESULTS: </strong>It was found that 184 patients had echogenic mass with shadowing on ultrasonography; yielding a prevalence of 10.2% for gallstones in the study participants. The occurrence was higher in females (14.8%) than in male participants (5.7%). Further, participants over 40 years of age and single, widow/separated subjects had higher incidence of gallstones than married individuals. Moreover, an indirect correlation was obtained with daily physical activity, consumption of fruits, vegetables and fish with development of GD.</p><p><strong>CONCLUSION: </strong>It can be evaluated that daily physical activity, female gender, increasing age and marital status play an important role in progression of GSD. Understanding pathogenesis and physiological mechanism involved in GSD can help to determine therapeutic options other than surgical treatment.</p>

Abstract Background Walking and cycling for transport (active travel) is an important source of physical activity with established health benefits. However, levels of physical activity accrued during public transport journeys in England are unknown. Methods Using the English National Travel Survey 2010–14 we quantified active travel as part of public transport journeys. Linear regression models compared levels of physical activity across public transport modes, and logistic regression models compared the odds of undertaking 30 min a day of physical activity. Results Public transport users accumulated 20.5 min (95% confidence interval=19.8, 21.2) a day of physical activity as part of public transport journeys. Train users accumulated 28.1 min (26.3, 30.0) with bus users 16.0 min (15.3, 16.8). Overall, 34% (32%, 36%) of public transport users achieved 30 min a day of physical activity in the course of their journeys; 21% (19%, 24%) of bus users and 52% (47%, 56%) of train users. Conclusion Public transport use is an effective way to incorporate physical activity into daily life. One in three public transport users meet physical activity guidelines suggesting that shifts from sedentary travel modes to public transport could dramatically raise the proportion of populations achieving recommended levels of physical activity.

The purpose of this study was to examine the association between self-reported physical activity (PA) and mean common carotid artery intima–media thickness (CCA IMT) among older adults. The data are from 1,811 Cooper Center Longitudinal Study participants, who were aged ≥60 years, with no history of cardiovascular disease. A medical history questionnaire was used to assess PA. Carotid ultrasound was performed to measure CCA IMT and the presence of plaque and stenosis. Logistic regression models were constructed to estimate the association between PA and CCA IMT after adjustment for covariates. The participants were aged 69.2 ± 5.9 years, and the majority were male (73.3%) and White (96.7%). The odds ratio of abnormal thickening of CCA IMT was 0.72 (95% confidence interval [0.54, 0.96]) in physically active participants (≥500 metabolic equivalent·min/week) after adjustment for covariates. In the current study, meeting PA guidelines in older adulthood was associated with lower odds of abnormal thickening of CCA IMT.

Abstract Background The causal effect of physical activity on reducing dementia risk has been questioned due to the possibility of reverse causation. This study examined the potential causal effects of physical activity on reducing dementia risk using residency in a snowy area as an instrumental variable (IV) representing the physical activity of older adults. Methods We used cohort data from the Japan Gerontological Evaluation Study, a longitudinal cohort enrolling people aged 65 or older who were physically and cognitively independent in 2013; study participants were followed for an average of 5.7 years. Participants in the present study included 73,260 individuals living in 19 municipalities in Japan. Physical activity was measured by self-report questionnaires and the incidence of dementia was ascertained by linking participants to the public registries of long-term care insurance. IV estimation was obtained from a piecewise Cox proportional hazard model using a two-stage regression procedure. Results During the study period, we ascertained 8714 cases (11.9%) of dementia onset. In the IV analysis, we found that the frequency of physical activity per week was negatively associated with dementia risk, though the association weakened over time (Year 1: hazard ratio = 0.53, 95% confidence interval: 0.39–0.74; Year 4: 0.69, 0.53–0.90; Year 6: 0.85, 0.66–1.10). Conclusions Our IV analysis indicated a potential causal effect of physical activity on reducing dementia risk that persisted for at least 4 years of follow-up. Thus, we conclude that physical activity should be recommended for older adults to reduce dementia risk.

Background: Given the health and cost burden of cardiovascular (CV) disease, we aimed to describe the trends in CV risk factors (CRF) in the US over the last twelve years, and quantify the disparities in healthcare by socioeconomic status (SES). Methods: The 2002-2013 Medical Expenditure Panel Survey (MEPS), a nationally representative sample was the basis for our study. CRFs (hypertension, diabetes mellitus, hypercholesterolemia, smoking, lack of physical activity and obesity) were identified by ICD9CM codes and/or self-report. Individuals were stratified by income level (per the federal poverty level), and proportions and logistic regression models were used to study trends and relationships for each CRF in two-year intervals. All analyses took into consideration the survey’s complex design. Inclusion criteria: age ≥ 18, BMI ≥ 18.5 and a positive sampling weight. Results: The study sample consisted of 250,371 MEPS participants (46 ± 14 years of age, 49% male), translating into 1.3 billion US adults. During the study period, the proportion of individuals with obesity increased overall, though moreso among people of low SES (Table). Trends in diabetes prevalence increased (from 9.6% to 12.8% in “Poor/Near Poor” and 5.6% to 8.3% in “High Income”, both p trend < 0.001) and hypertension (from 28.5% to 36.3% in “Poor/Near Poor” and 24.2% to 33.4% in “High Income”, both p trend < 0.001), though the greatest relative change was observed among the Middle/High Income SES group. Prevalence of inadequate physical activity increased in all SES categories, with the “Poor/Near Poor” group having the most drastic change (32.4% vs. 55.4%, p trend < 0.001), and a relative percent change of 71.1% increase in this category. Smoking declined across time in all SES categories, and hypercholesterolemia showed no significant changes. In pooled analysis, the odds of having a “Poor CRF Profile” (≥ 4 CRFs) for “Poor/Near Poor” SES were 36% higher when compared to “High Income” SES (OR 1.36, 95% CI [1.30, 1.44]) (Table). Conclusion: Disparities in the prevalence of CRFs have increased over the past 12 years, and have worsened for some conditions, including obesity, diabetes, hypertension and physical inactivity. There is a need for healthcare initiatives and policies to target the groups most in need.

AbstractObjectivesPhysical activity has been proposed as a protective factor for COVID-19 hospitalization. However, the mechanisms underlying this association are unclear. Here, we examined the association between physical activity and COVID-19 hospitalization and whether this relationship was explained by other risk factors for severe COVID-19.MethodWe used data from adults aged 50 years and older from the Survey of Health, Ageing and Retirement in Europe. The outcome was self-reported hospitalization due to COVID-19 measured before August 2020. The main exposure was usual physical activity, self-reported between 2004 and 2017. Data were analyzed using logistic regression models.ResultsAmong the 3139 participants included in the study (69.3 ± 8.5 years, 1763 women), 266 were tested positive for COVID-19 and 66 were hospitalized. Results showed that individuals who engaged in physical activity more than once a week had lower odds of COVID-19 hospitalization than individuals who hardly ever or never engaged in physical activity (odds ratios = 0.41, 95% confidence interval = 0.22–0.74, p = .004). This association between physical activity and COVID-19 hospitalization was explained by muscle strength, but not by other risk factors.ConclusionThese findings suggest that, after 50 years of age, engaging in physical activity more than once a week is associated with lower odds of COVID-19 hospitalization. The protective effect of physical activity on COVID-19 hospitalization is explained by muscle strength.
