Sedentary Behavior, Physical Activity, Social Participation, and Loneliness Among Community-Dwelling Older Adults in China

Aiqin Chu, Ye Lu, Hailing Zhang, and Yan Jiang

This study examined the relationship between loneliness, sedentary behavior, physical exercise, and social participation in Chinese older adults, and provided ideas to formulate preventive strategies that can help reduce loneliness. Data on demographics, health behavior, social participation, and loneliness were collected from a cross-sectional study of 629 older adults in Hefei, Anhui province, from June to August 2020. After adjusting for age, income, religion, marital status, and chronic illness demographic variables, sedentary behavior (β = 0.111, SE = 0.671, p = .001), physical exercise (β = −0.229, SE = 0.358, p < .001), and social participation (β = −0.329, SE = 0.086, p < .001) were found to be significantly correlated with loneliness in older adults. These findings suggest that a higher level of loneliness may be linked to greater sedentary behavior, less social engagement, and decreased physical exercise among older men and women.

Exercise Intensity Among Older Adults Participating From Home in Remotely Delivered EnhanceFitness

Nancy M. Gell, Yang Bai, Melanie Herbert, Elise V. Hoffman, Rebecca Reynolds, Myeongjin Bae, Kim Dittus, Elizabeth A. Phelan, and Kushang V. Patel

We aimed to examine exercise intensity among older adults participating from home in remotely delivered EnhanceFitness (Tele-EF). Exercise intensity was assessed through Fitbit-measured heart rate and the Borg 10-point rating of perceived exertion over 1 week of a 16-week exercise program. Outcomes included mean minutes spent at or above the heart rate reserve calculated threshold for moderate intensity and mean rating of perceived exertion. Pearson and Spearman rank correlations were used to examine associations between baseline characteristics with exercise intensity. During the 60-min classes, the 55 participants achieved moderate intensity for a mean of 21.0 min (SD = 13.5) and had a mean rating of perceived exertion of 4.9 (SD = 1.2). There were no significant associations between baseline characteristics and exercise intensity. Older adults can achieve sustained moderate-intensity exercise during Tele-EF supervised classes. Baseline physical function, physical activity, and other health characteristics did not limit ability to exercise at a moderate intensity, though further investigation is warranted.

Exercise and Health Anxiety in Older Women: Exploring the Mediating Role of Anxiety Sensitivity

Kyoungsil Nah and Janine V. Olthuis

Research shows that health anxiety significantly affects older adults’ health and quality of life. Although exercise may be associated with lower health anxiety, research on older adults is limited, and the mechanism remains unknown. This study examined the association between exercise and health anxiety in older women and the mediating role of anxiety sensitivity in this association. Participants were 166 women aged 65+ years, without health problems that prevented them from exercising. Participants were recruited via Facebook advertisements. They completed an online self-report questionnaire including measures of health anxiety, physical activity, and anxiety sensitivity. The SPSS PROCESS macro was used to examine the association between exercise and health anxiety, and the role of anxiety sensitivity as a mediator. Results indicated that greater participation in exercise was associated with lower health anxiety, and anxiety sensitivity mediated the association. Findings suggest that exercise-based interventions might prevent health anxiety in older adults.

Determination of a Low Skeletal Muscle Mass Index Using the Mass of the Gluteus Medius in Older Patients With Hip Fractures

Ryo Shiraishi, Keisuke Sato, Nami Shiraishi, Sadao Yoshida, Takahiro Ogawa, and Masaki Suenaga

This study evaluated the relationship between the muscle mass of the gluteus medius (GM) and skeletal muscle mass index (SMI) measured in patients with hip fractures. In this study, 141 patients with hip fractures were divided into those with high or low SMI. The GM index (GMI) was calculated by dividing the GM by the square of the height in meters. The correlation between GMI and SMI was subsequently analyzed, and cutoff values for determining the loss of skeletal muscle mass were calculated using the receiver operating characteristic curve. GMI and SMI showed a positive correlation for both sexes (male: r = .890, female: r = .626, p < .001). The GMI cutoff values were 19.460 cm2/m2 for males and 17.850 cm2/m2 for females. Skeletal muscle mass evaluation of the GM could contribute to hip fracture recovery by improving mobility and facilitating the early diagnosis of loss of SMM.

Reduced Cross-Sectional Area of the Gluteus Medius Muscle is Associated With Decreased Activities of Daily Living in Older Adult Patients With Hip Fractures

Ryo Shiraishi, Keisuke Sato, Nobumasa Chijiiwa, Sadao Yoshida, and Takahiro Ogawa

We investigated the association between the cross-sectional area (CSA) of the gluteus medius muscle (GMM) and activities of daily living in patients with hip fractures. This retrospective cohort study comprised 111 patients aged ≥65 years who underwent hip fracture rehabilitation. The CSA of the GMM was measured using computed tomography scans in the early stages of hospitalization. The group with decreased CSA of the GMM had a median GMI ≤17 cm2/m2 for male patients and ≤16 cm2/m2 for female patients. Patients in the group with decreased CSA of the GMM had lower functional independence measure gains than those in the control group. After adjusting for confounders, we found that decreased CSA of the GMM was significantly associated with lower functional independence measure gains (β: −0.432, p < .001). In patients with hip fractures, decreased CSA of the GMM was associated with decreased activities of daily living.

Differences in Habitual and Maximal Gait Velocity Across Age Groups: A Cross-Sectional Examination

Sally Paulson, Joshua L. Gills, Anthony Campitelli, Megan D. Jones, Joohee I. Sanders, Jordan M. Glenn, Erica N. Madero, Jennifer L. Vincenzo, Christopher S. Walter, and Michelle Gray

Prior work, primarily focusing on habitual gait velocity, has demonstrated a cost while walking when coupled with a cognitive task. The cost of dual-task walking is exacerbated with age and complexity of the cognitive or motor task. However, few studies have examined the dual-task cost associated with maximal gait velocity. Thus, this cross-sectional study examined age-related changes in dual-task (serial subtraction) walking at two velocities. Participants were classified by age: young-old (45–64 years), middle-old (65–79 years), and oldest-old (≥80 years). They completed single- and dual-task walking trials for each velocity: habitual (N = 217) and maximal (N = 194). While no significant Group × Condition interactions existed for habitual or maximal gait velocities, the main effects for both condition and age groups were significant (p < .01). Maximal dual-task cost (p = .01) was significantly greater in the oldest-old group. With age, both dual-task velocities decreased. Maximal dual-task cost was greatest for the oldest-old group.
