Brynn Adamson, Matthew Adamson, Dominique Kinnett-Hopkins, and Robert Motl

those with disabilities. Methods Study Design This study was a secondary data analysis (SDA) and synthesis of two qualitative studies on exercise practices among those with MS. Initial analyses uncovered themes related to ableism, compulsory able-bodiedness, medicalization of exercise, and shame. These

Physical Activity and Mental Health of Parents of Children With Autism Spectrum Disorder

Xiaoxia Zhang, Zackary G. Kern, and Joonkoo Yun

This study aimed to examine physical activity (PA) levels and mental health status (i.e., anxiety and depression) among parents of children with autism spectrum disorder (ASD). Secondary data analysis was conducted using the 2018 National Health Interview Survey. We identified 139 parents of children with ASD and 4,470 parents of children with no disability. Their PA levels, anxiety, and depression were analyzed. Compared with parents of children with no disability, parents of children with ASD were significantly less likely to meet the PA guideline for Americans and had lower odds of vigorous PA (aOR = 0.702), strengthening PA (aOR = 0.885), and light to moderate PA (aOR = 0.994). Parents of children with ASD reported significantly higher odds of anxiety (aOR = 1.559) and depression (aOR = 1.885). This study revealed lower PA levels and higher risks of anxiety and depression in parents of children with ASD.

International Differences in Management of Physical Activity Data: Can They Explain Some of the Difference in Prevalence Estimates?

Wendy J. Brown and Yvette D. Miller


National physical activity data suggest that there is a considerable difference in physical activity levels of US and Australian adults. Although different surveys (Active Australia and BRFSS) are used, the questions are similar. Different protocols, however, are used to estimate “activity” from the data collected. The primary aim of this study was to assess whether the 2 approaches to the management of PA data could explain some of the difference in prevalence estimates derived from the two national surveys.


Secondary data analysis of the most recent AA survey (N = 2987).


15% of the sample was defined as “active” using Australian criteria but as “inactive” using the BRFSS protocol, even though weekly energy expenditure was commensurate with meeting current guidelines. Younger respondents (age < 45 y) were more likely to be “misclassified” using the BRFSS criteria.


The prevalence of activity in Australia and the US appears to be more similar than we had previously thought.

Exploring Fear of Falling and Exercise Self-Efficacy in Older Women With Vertebral Fractures

Matteo Ponzano, Jenna C. Gibbs, Jonathan D. Adachi, Maureen C. Ashe, Angela M. Cheung, Keith D. Hill, David Kendler, Aliya A. Khan, Caitlin McArthur, Alexandra Papaioannou, Lehana Thabane, John D. Wark, and Lora M. Giangregorio

Fear of falling is a common issue among older adults, which decreases quality of life and leads to an avoidance of activities they are still able to do. The goal of this secondary data analysis was to explore the relationship between fear of falling and exercise self-efficacy in 141 women with at least one nontraumatic Genant Grade 2 vertebral fracture. Fear of falling, exercise self-efficacy, history of falling, the number of falls, the use of assisting devices, and pain at rest or during movement were obtained using medical history and health status questionnaires. There was a negative association between fear of falling and exercise self-efficacy (pseudo R 2 = .253; p = .004), which persisted when the analysis was adjusted for history and number of falls, use of assistive devices, and pain at rest (pseudo R 2 = .329; p < .0001) or during movement (pseudo R 2 = .321; p < .0001). Fear of falling may be negatively associated with exercise self-efficacy in older women with vertebral fracture.

Waist Circumference, Physical Activity, and Functional Impairments in Older U.S. Adults: Results from the NHANES 2005–2010

John A. Batsis, Cassandra M. Germain, Elizabeth Vásquez, Francisco Lopez-Jimenez, and Stephen J. Bartels

Physical activity (PA) improves function in older obese adults. However, body mass index is an unreliable adiposity indicator better reflected by waist circumference (WC). The impact of PA on physical impairment and mobility with high WC is unclear. We performed a secondary data analysis of 4,976 adults ≥ 60 years of age using the National Health and Nutrition Examination Survey (NHANES) 2005–2010. Physical limitations (PL), activities of daily living (ADL) impairments, and PA (low = < 1 day/week or high = > 1 day/week) were self-reported. WC was dichotomized (females: 88 cm; males: 102 cm). Mean age was 70.1 years and 55.1% were female. Prevalence of PL and ADL impairment in the high WC group were 57.7% and 18.8%, respectively, and high PA was present in 53.9%. Among those with high WC, high PA vs. low PA participants were at lower risk of PL (OR 0.58 [0.48−0.70]) and ADL impairment (OR 0.46 [0.32−0.65]). Those with high WC had higher odds of PL irrespective of PA (high PA: OR 1.57 [1.30−1.88]; low PA: OR 1.52 [1.29−1.79]) and ADL impairment (high PA: OR 1.27 [1.02−1.57] and low PA: OR 1.24 [0.99−1.54]). High PA in viscerally obese individuals is associated with impairments.
