Comparative Study of the Effects of Tai Chi and Square Dance on Immune Function, Physical Health, and Life Satisfaction in Urban Empty-Nest Older Adults

The association between leisure activity and mental health in the older adults in China: amazing Guangchangwu

Objective

Since the mental health of older adult is an important topic in the aging society, the main purpose of this study is to understand the mental health status of the older adult in China under different conditions. More importantly, although people generally believe that leisure activities can improve mental health, the impact of these activities on older adult has not yet been fully discussed. Hence, this study further explores that what kind of leisure activity is associated with mental health of the older adult given different conditions.

Methods

We conducted a cross-sectional questionnaire survey to explore the relationships of various leisure activities on mental health among older adults under different demographics. This study used the Geriatric Depression Scale short forms scale (GDS-15) to assess the mental health of older adults. Based on a sample of 2,006 participants, both two-sample t-test and ANOVA were adopted to analyze the characteristics of mental health among specific subsamples.

Results

Our findings indicated that older adults generally have higher mental health scores if they do not have chronic diseases, live with other family members, or reside in urban. First, three leisure activities including walking, Guangchangwu, and hiking have positive associations on mental health for older adults with chronic diseases. Second, the older adults living alone engaged in Guangchangwu or hiking significantly associated with their good mental health. Finally, only Guangchangwu has a significantly positive associated with the mental health of rural older adults.

Conclusions

Based on our results, the government and healthcare planners can better allocate limited resources under different conditions to promote certain leisure activities, which are helpful to enhance the mental health of older adults. Guangchangwu is an activity that meets the characteristics of Chinese culture, so we further conclude that it is significantly associated with the good mental health of older adults in China.

The effect of aerobic dancing on physical fitness and cognitive function in older adults during the COVID-19 pandemic-a natural experiment

During the Coronavirus disease (COVID-19), the physical activity of older adults is at a lower level. The study aimed to examine the effectiveness of aerobic dancing on physical fitness and cognitive function in older adults. We conducted a randomized controlled trial with 34 older adults who were assigned into an aerobic dancing group and a control group. Three dance sessions weekly for 60 ​min were scheduled for the aerobic dancing group for a total of 12 weeks. Physical fitness, blood pressure, lipids, glucose, cognitive function were assessed before and after the intervention. Baseline adjusted Analysis of Covariance (ANCOVA) was used to determine whether outcome variables varied between groups at pre-test and post-test. Effect size (Cohen's d) was calculated to determine the differences between groups from baseline to post-test. After 12 weeks, we found that the aerobic dancing group showed significant improvement in memory (portrait memory: F ​= ​10.45, p ​= ​0.003, d ​= ​1.18). The Limit of Stability (LOS) parameters in the aerobic dancing group displayed a significant increase after the intervention (right angle: F ​= ​5.90, p ​= ​0.022, d ​= ​0.60; right-anterior angle: F ​= ​4.23, p ​= ​0.049, d ​= ​0.12). Some beneficial effects were found on flexibility, grip strength, balance and subjective well-being (sit and reach: F ​= ​0.25, p ​= ​0.62, d ​= ​-0.40; grip strength: F ​= ​3.38, p ​= ​0.08, d ​= ​0.89; one-legged standing with eyes closed: F ​= ​1.26, p ​= ​0.27, d ​= ​0.50) in the aerobic dancing group. Aerobic dancing training was effective in improving memory and balance ability in older adults during the COVID-19 pandemic in China. In the future, aerobic dancing is a promising tool to encourage physical activity in older adults.

Neighborhood health effects on the physical health of the elderly: Evidence from the CHRLS 2018

Background

There are more than 26 million elderly people in China, and due to the Health China strategy proposed in 2020, “Elderly Health” has become an important topic of concern for all sectors of society. Neighborhoods provide important social relationships. However, Chinese researchers have not extensively explored the impact of these relationships on the physical health of the elderly.

Methods

Based on the data from the 2018 China Health and Retirement Longitudinal Study (CHARLS), we constructed a comprehensive research framework integrating ordinary least square (OLS) regression, heterogeneity analysis, IV-2SLS, robustness testing, and Karlson–Holm–Breen (KHB) mediating effect analysis, which can be used to thoroughly examine neighborhood health effects (NHEs) in relation to the physical health of the elderly.

Results

The OLS results showed that the NHEs (B = 0.4689, p < 0.01) had a positive influence on the physical health of the elderly, and were lower than the NHEs estimated by IV-2SLS (B = 0.5018, p < 0.01). The mediating effects of social networks and social relationships were analyzed using KHB, and both the total (B = 0.6056, p < 0.01) and indirect (B = 0.0800, p < 0.01) effects on neighborhood health were significant, with the total effect being 10 times larger than the direct effect and 13.24% of the total effect coming from the mediating variable.

Conclusions

Firstly, the NHEs positively influence the physical health of elderly persons, but there are heterogeneous differences. Secondly, the IV-2SLS estimation results suggest that not controlling for endogeneity leads to underestimation of the role of the NHEs. Thirdly, using the county-level NHEs, self-rated health, and health changes to replace variables, and grouping by smokers (small sample) and never smoked (large sample), the influence of the NHEs on the physical health of the elderly is robust. Finally, social networks and social relationships are important transmission mechanisms of the NHEs when it comes to the physical health of the elderly.

•

NHEs are robust and significant in the Chinese social background.

•

Community (county) level NHEs are positive for the positive health of the elderly.

•

NHEs have a positive impact on self-rated health and health changes in older adults.

•

Endogenous issues would underestimate the role of NHEs.

•Social networks and social relationships are transmission mechanisms of the NHEs.

Subjective Exercise Experience and Group Cohesion among Chinese Participating in Square Dance: A Moderated Mediation Model of Years of Participation and Gender

(1) Background: This study aimed to explore the relationship between years of participation, subjective exercise experience, and group cohesion among gender-specific square dance practitioners. (2) Methods: The Subjective Exercise Experience Questionnaire (SEEQ) and Group Environment Questionnaire (GEQ) were used to evaluate Subjective Exercise Experience (SEE) and group cohesion (GC). An analysis was conducted on 130 Chinese (63 males and 67 females) using multiple group analysis within a structural equation model. (3) Results: (a) The positive aspects of Subjective Exercise Experience (SEE) and Positive Well-Being (PWB), had a strongly positive effect on GC in both groups. The negative aspects of SEE, Psychological Fatigue (PF), and Psychological Distress (PD), had negative effects on GC. (b) Only for the male group was there an indirect effect of participation years on the association between SEE and GC in the model (a × b = 0.062, 95% CI [0.001, 0.181]; standard error (SE) = 0.062, p = 0.048). (c) The significant differences between paths coefficients were noticed in the association of years of participation with SEE (t = -2.043) and GC (t = -1.962). (4) Conclusion: Based on these results, gender differences in terms of the partial mediating role of adherence in the relationship of SEE and GC were presented for future research, fitness popularization, and society.

Effect of Square Dance Interventions on Physical and Mental Health among Chinese Older Adults: A Systematic Review

(1) Background: Square dancing is an emerging form of aerobic exercise in China, especially among middle-aged and older people. The benefits of square dancing have been investigated and promoted in recent years through research and interventions. Interventions have been conducted to promote the participants’ reactionary participation in physical activity, social and family cohesion, and other psychological benefits. Therefore, square dancing has been promoted as a major factor in China’s increase in physical activity prevalence. (2) Methods: A systematic review was used to identify studies that have indicated the effect of square dancing on the physical and mental health among Chinese older adults. (3) Results: Twenty-four studies examining the effects of square dancing on older Chinese adults were extracted. These studies were not found in English databases. The quality of the retrieved studies had a moderate-to-high risk of bias. Square dancing interventions were shown to result in effective mental, physical, and cognitive improvements in the systematic synthesis. (4) Conclusions: This study examined the effects of square dancing in China over the past 10 years on the physical and mental health of older adults. Based on the results of this study, recommendations can be made for future square dance interventions for older adults such as male-oriented, mixed-gender, or intergenerational programs.
