Comparison of Participation in Strength Activity Between Wearable Device Users and Nonusers: 2017 Behavioral Risk Factors Surveillance System

Willie Leung, Lu Shi, and Jaehun Jung

Background: There are many benefits associated with engaging in strength physical activity. Many studies did not examine the engagement of strength activity among wearable device users. This study aimed to examine the association between wearable device usage and engagement of strength activity in free-living settings using nationally representative data. Methods: A total of 8250 adult wearable device users and nonusers from 8 states of the 2017 Behavioral Risk Factors Surveillance System were included in analysis. Multiple regression models were performed to determine the association between the dependent variables of strength activities and the independent variable of wearable devices. Results: Wearable device users were 1.26 (95% confidence interval, 1.01–1.81) times the odds of nonusers in engaging in strength activity. Users also had higher odds of meeting both the strength and aerobic physical activity guidelines than nonusers (odds ratio = 1.49; 95% confidence interval, 1.07–2.06; adjusted odds ratio = 1.43; 95% confidence interval, 1.02–2.00). No associations were found between wearable device utilization and frequency of strength activity per week. Conclusion: Wearable device users were more likely to engage in strength activity than nonusers. However, additional studies are needed to determine the effectiveness of wearable devices in promoting strength activity.

Meta-Analysis of Physical Activity Levels in Youth With and Without Disabilities

Jaehun Jung, Willie Leung, Bridgette Marie Schram, and Joonkoo Yun

The purpose of this study was to explore the current levels of physical activity among youth with disabilities using meta-analysis. The search identified 11 publications including 729 participants (age 4–20 yr). The overall effect size for 11 studies was Hedges g = 0.60 (SE = 0.18, 95% confidence interval [CI] [0.24, 0.96], p < .05, k = 11) using a random-effects model. The findings suggest that differences in physical activity levels between youth with and without disabilities are complex. Results indicated that youth without disabilities engaged in higher levels of physical activity of moderate to vigorous intensity (g = 0.66, SE = 0.18, p < .05). However, no differences were found in light-intensity physical activity (g = −0.03, SE = 0.16, p > .85). Results also suggested that the differences in physical activity between youth with and without disabilities were affected by age (<12 yr, g = 0.83, SE = 0.24, 95% CI [0.37, 1.29], p < .05, and >13 yr, g = 0.37, SE = 0.10, 95% CI [0.18, 0.57], p < .05; Q value = 3.20, df = 1, p < .05), with children with disabilities engaging in less physical activity than children without disabilities in younger ages. Differences in physical activity level between youth with and without disabilities are functions of intensity of physical activity and age but may not be of type of disability (Q value = 0.22, df = 1, p > .6).

Physical Educators’ Qualifications and Instructional Practices Toward Students With Disabilities

Jaehun Jung, Layne Case, Samuel W. Logan, and Joonkoo Yun

The purposes of this study were (a) to investigate the prevalence of physical educators who report delivering high-quality instructional practices to students with disabilities and (b) to examine the relationships between teachers’ qualifications and the delivery of high-quality instructional practices. A secondary analysis using data from the School Health Policy and Practice Study 2014 data set was employed. The analytic sample included 256 physical educators who taught students with disabilities. Prevalence estimates of physical educators who reported using high-quality instructional practices were calculated. Two separate binary logistic regressions using weighted data were conducted to evaluate the relative contribution of (a) teacher qualifications and (b) educational degrees in accounting for differences in the use of high-quality instructional practices. Less than half of the sample reported using high-quality instructional practices. Considering the increasing prevalence of students with disabilities in general education classrooms, teacher education programs should prioritize providing teacher candidates with coursework that aligns with the expectations of physical educators who teach students with disabilities.

Comparison of Participation in Strength Activity Among People With and Without Disabilities: 2013–2017 Behavioral Risk Factor Surveillance System

Willie Leung, Ming-Chih Sung, Jinhyun Lee, Jaehun Jung, Nicole Fiscella, and Lu Shi

Background: The current physical activity guidelines recommend engagement in strength activities at least 2 days per week. Currently, there is a lack of literature examining strength activities among people with disabilities. The purpose of this study is to estimate and compare the prevalence of engagement in strength activities and adherence to strength activity guidelines among adults with and without disabilities in the United States. Methods: A total of 1,005,644 adults (18–80 y old) with and without disabilities from the 2013 to 2017 Behavioral Risk Factor Surveillance System were included in this secondary data analysis. Descriptive analyses were performed to describe the prevalence of strength activity behaviors of adults with and without disabilities. Logistic and Poisson regression models were performed to evaluate the relative contribution of disability status on strength activity behaviors. Results: A higher proportion of participants without disabilities (46.42%, 95% CI, 46.18–46.65) reported engaging in strength activities compared with participants with disabilities (30.68%, 95% CI, 30.29–31.08; P < .01). Participants with disabilities were less likely to engage in strength activities (odds ratio = 0.51, 95% CI, 0.50–0.52; adjusted odds ratio = 0.75, 95% CI, 0.73–0.77) and meet strength activity guidelines (odds ratio = 0.56, 95% CI, 0.54–0.57; adjusted odds ratio = 0.75, 95% CI, 0.73–0.77) than participants without disabilities. Conclusion: Experiencing a disability is associated with lower engagement in strength activities; thus, it is important to identify effective and efficient approaches to promoting strength activities among people with disabilities.
