Effects of Tai Chi and Qigong on cognitive and physical functions in older adults: systematic review, meta-analysis, and meta-regression of randomized clinical trials.

BACKGROUND: Older adults experience age-related declines in physical and cognitive functions due to interactions between aging and chronic diseases. Tai Chi and Qigong (TCQ) might be beneficial in improving the physical function and delaying the cognitive decline of this population. The potential underlying mechanism was explored to determine the effects of TCQ on cognitive function via direct or indirect pathways. PURPOSE: The objective of this systematic review was to determine the effects of TCQ on cognitive and physical functions in older adults using meta-analysis, and to determine the impact of TCQ on cognitive function while controlling for physical function using a meta-regression approach. METHODS: A systematic search of 13 electronic databases (in English, Korean, and Chinese languages) identified 10,292 potentially eligible studies published between inception and May 2022. The bias in individual studies was assessed using the Cochrane Risk of Bias (version 2.0) tool. The heterogeneity of the studies was evaluated using a 95% prediction interval, and the meta-analysis and meta-regression were implemented using the Comprehensive Meta-Analysis (version 3) software. RESULTS: Our search identified 17 randomized studies (n = 2,365, mean age = 70.3 years). The results of the meta-analysis that used a random-effects model indicated that TCQ had significant effects on both cognitive (Hedges' g = 0.29, 95% confidence interval [CI] = 0.17 to 0.42) and physical (Hedges' g = 0.32, 95% CI = 0.19 to 0.44) functions. We used meta-regression to explore the effect size of TCQ in association with physical function level. The regression model was significant (Q = 25.01, p = .070), and 55% of the heterogeneity was explained by physical function as a moderator variable. The effects of TCQ on cognitive function remained significant in this model when controlling for the effect of physical function (ß = 0.46, p = .011). CONCLUSION: This meta-regression of 17 randomized studies strongly suggests that TCQ has beneficial effects on physical and cognitive functions in older adults. The effect of TCQ on cognitive function remained significant after taking into account the significant effects of physical function as a moderator. The findings imply the potential health benefits of TCQ by promoting cognitive function in older adults directly and indirectly through enhancing physical function.

Effects of Tai Chi and Qigong on the mobility of stroke survivors: A systematic review and meta-analysis of randomized trials.

BACKGROUND: Stroke survivors often experience impaired mobility and physical functions. Tai Chi and Qigong have been shown to have physical and psychological benefits for stroke patients. PURPOSE: To summarize the evidence on Tai Chi and Qigong for improving mobility in stroke survivors, specifically the ability to walk, dynamic balance, and activities of daily living (ADL). METHODS: Independent searches of 16 electronic databases in English, Korean, and Chinese from their inception until December 2021 were conducted by two research teams. Methodological quality was assessed using Cochrane's risk of bias tool 2.0. Comprehensive Meta-Analysis 3.0 software was used to calculate effect sizes with subgroup analysis and to assess heterogeneity and publication bias. RESULTS: The meta-analysis included 27 randomized trials (18 with Tai Chi and 9 with Qigong) on stroke survivors (N = 1,919). None of the studies were considered at high risk of bias, about 70% had some concerns, and 30% were considered low risk. Meta-analysis of 27 randomized controlled trials with random-effects models indicated that Tai Chi and Qigong effectively improved mobility, specifically on the ability to walk (Hedges'g = 0.81), dynamic balance (Hedges'g = 1.04), and ADL (Hedges'g = 0.43). The effects of Tai Chi and Qigong were significant for short-term and long-term programs (Hedges'g 0.91 vs. 0.75), and when compared with active controls and no treatment group (Hedges'g 0.81 vs. 0.73). CONCLUSION: Tai Chi and Qigong performed for 12 weeks or less were effective in improving the mobility of stroke survivors. Further studies are warranted to assess whether Tai Chi and Qigong work best as an adjunct to rehabilitation, an effective alternative to rehabilitation or as a maintenance strategy, and whether the results could be further optimized by assessing different schools of Tai Chi and Qigong, different types of stroke patients, and different points in the post-stroke recovery process.

Sex-Based Differences in Factors Associated With Sugar-Sweetened Beverage Consumption Among Korean High School Students.

This study aimed to identify sex-based differences in the individual and environmental factors associated with sugar-sweetened beverage (SSB) consumption among Korean high school students. Secondary data were obtained from the 15th (2019) Korea Youth Risk Behavior Web-based Survey. In this study, we analyzed data from 13,066 high school students (5,874 boys and 7,192 girls) who answered questions regarding SSB consumption and individual and environmental factors. Complex sampling analysis (descriptive statistics and logistic regression analysis) was conducted using the SPSS Statistics 26.0 software. Most adolescents (97% boys and 95.2% girls) reported having consumed SSBs in the last seven days. Individual factors, such as increased stress, sleep dissatisfaction, and fast-food intake (more than thrice a week) were positively associated with SSB consumption among adolescent boys and girls. Environmental factors like high education levels (above college) of mothers were negatively associated with SSB consumption among both boys and girls. Furthermore, current alcohol consumption, smoking, low vegetable intake (less than thrice a week) in boys, and more than 2 h a day of screen-based sedentary behavior in girls were positively associated with SSB consumption. According to the results, individual factors associated with SSB consumption varied according to the sex of adolescents. Thus, sex differences in factors associated with SSB consumption in adolescents should be considered as basic knowledge for developing strategies for reducing SSB consumption.

Mediating effect of the parent-child relationship on the association between parenting stress and children's eating behaviors.

BACKGROUND: Emerging evidence suggests that parenting stress plays a significant role in children's eating behavior. However, the nature of the relationship between parenting stress and children's health behaviors is still not well understood, possibly because there is limited understanding of the mediating factors. The purpose of this study was to examine the mediating effect of the parent-child relationship on the association between parenting stress and children's eating behaviors in families with young children. METHODS: Using a cross-sectional study design, we recruited mothers of families with children aged four to six years in the United States. We asked the mothers select one child if she has more than one eligible child. Mothers answered well-validated questionnaires regarding parenting stress, the parent-child relationship, and children's eating behaviors. We utilized a structural equation model to analyze the mediating factors. RESULTS: A total of 172 mothers of children participated in this study. The children's mean age was 4.92 (SD 0.89) years; 50% of children were female and 71.2% were non-Hispanic Whites. Parenting stress was associated with subcategories of the parent-child relationship (satisfaction with parenting [b* = - 0.69, p < .01], communication [b* = 0.45, p < 0.01], and limit setting [b* = - 0.82, p < .01]). The subcategories of communication and limit setting were negatively associated with food responsiveness in children (b* = - 0.24, p < .01; b* = - 0.46, p < .01, respectively). Limit setting was negatively associated with emotional overeating in children (b* = - 0.49, p < .01). Communication mediated the association between parenting stress and food responsiveness in children (b* = - 0.11, p < .01). The mediating role of limit setting was established in the association between parenting stress and food responsiveness as well as in the association between parenting stress and emotional overeating (b* = 0.38, p < .01; b* = 0.40, p < .01, respectively). CONCLUSIONS: The parent-child relationship is an important component in improving children's eating behaviors in families that have parents with higher parenting stress levels.

Effects of self-management programs on behavioral modification among individuals with chronic disease: A systematic review and meta-analysis of randomized trials.

The prevalence of chronic disease associated with unhealthy lifestyles has been increasing worldwide. Health professionals have recognized that self-management programs (SMPs) can provide health benefits by promoting health behaviors, especially when applied to individuals with lifestyle-related chronic disease. This review performed a meta-analysis of the features of SMPs using randomized studies and analyzed the magnitude of the combined effects of self-management on behavioral modification. We searched the PubMed, CINAHL, ScienceDirect, SCOPUS, Web of Science, Embase, Cochrane Library, DBpia, and KISS to identify randomized trials that evaluated the behavioral outcomes of SMPs. Subgroup analyses were performed for program duration, providers, type of comparisons, and program settings. We selected 25 studies (N = 5,681) to perform analyses with random-effects models. The effect sizes of SMPs were small but significant for physical activity (standardized difference in means [SDM] = 0.25), dietary habits (SDM = 0.28), and health responsibility (SDM = 0.18), and not significant for stress management and smoking behaviors. A short-term SMPs (less than 12 weeks) was indicated as being effective in modifying physical activity, dietary habits, and health responsibility, while the program effects on dietary habits were significant only with expert-delivered education and when compared with inactive controls. The findings of this study indicate that SMPs can effectively improve physical activity, dietary habits, and health responsibility in individuals with chronic disease, with a small but significant effect size. Future studies should explore the effects of SMPs on stress management and smoking cessation and assess the long-term maintenance of healthy lifestyles in individuals with lifestyle-related chronic disease.

Effects of a Tai Chi-Based Stroke Rehabilitation Program on Symptom Clusters, Physical and Cognitive Functions, and Quality of Life: A Randomized Feasibility Study.

Stroke survivors suffer from disease-associated symptoms. Tai Chi can be a beneficial approach to provide an adapted form of intervention to manage their symptoms. The study aimed to determine the effects of a Tai Chi-based stroke rehabilitation program on symptom clusters, physical and cognitive functions, and stroke-specific quality of life among stroke survivors in Korea. Thirty-four stroke survivors were randomly assigned to receive either the Tai Chi-based program or the stroke-symptom management program. The feasibility of the program and its effects on the outcomes were assessed at baseline, 3 months, and 6 months. Repeated measures ANOVA showed that most symptoms improved in both groups during the 6-month period, but swallowing-related symptoms improved significantly in the Tai Chi group. Based on the interaction effect, Tai Chi was more effective on flexor muscle strength, ambulation, and activities of daily living and cognitive function over 6 months than their counterparts. Among SS-QOL dimensions, the Tai Chi group showed significant improvements in the thinking and self-care dimensions. The Tai Chi-based stroke rehabilitation program was feasible and safely applicable to stroke survivors in the community settings. This program could improve symptoms, physical and cognitive function, leading to improvements in the self-care dimension of the SS-QOL among stroke survivors.

Motivational Factors for Smoking Behaviors in Individuals with Metabolic Syndrome.

PURPOSE: Smoking, which is one of the major risk factors for metabolic syndrome that causes cardiovascular disease or diabetes, is a crucial risk factor, which is modifiable. This study aimed to determine the factors that promote smoking behaviors according to smoking status among adults with metabolic syndrome. PATIENTS AND METHODS: A survey of structured self-reported questionnaires was conducted on 152 adults with metabolic syndrome. Outcome variables included cognitive motivations (self-efficacy, and perceived benefits and barriers), emotional motivation (emotional salience), and autonomous and controlled motivation based on self-determination theory. The participants were categorized by their smoking status (never smoking, quit smoking, or current smoking). Their sociodemographic and motivational factors were examined using one-way analysis of variance, analysis of covariance, and multinomial logistic regression analysis. RESULTS: Data on 152 individuals with metabolic syndrome with a mean age of 57.5 years were included. The findings indicated that the motivational factors for the never-smoking and quit-smoking groups significantly differed from those for the current-smoking group in terms of self-efficacy, perceived benefits, perceived barriers, and autonomous motivation. Based on multinomial logistic regression with current smoking as the reference group, sex (being female, OR=57.69) and perceived barriers (OR=0.39) were the significant predictors for the never-smoking group, while autonomous motivation (OR=1.96) was the significant predictor for the quit-smoking group. CONCLUSION: The motivational factors for smoking behaviors varied according to the smoking status of adults with metabolic syndrome. Autonomous motivation was the significant predictor of smoking cessation for individuals who successfully quit, whereas cognitive motivation was influential in the prevention of smoking by individuals who have never smoked. Further studies are warranted to develop smoking cessation strategies, which should focus on specific motivational factors to lead effective smoking prevention programs in this population.

Meta-analysis of the effects of smoking prevention programs for young adolescents.

PURPOSE: This meta-analysis aimed to analyze the effects of smoking prevention programs for young adolescents at early smoking stages to identify the appropriate characteristics of prevention programs for this population. METHODS: Searches of health-related databases and Google Scholar were conducted, and 23 randomized studies were included in the analysis. The main outcome variable was smoking behavior. The analysis was conducted using Comprehensive Meta-Analysis software (version 3.0). RESULTS: Smoking prevention programs significantly reduced smoking behaviors (OR=0.85, 95% CI=0.77-0.93). School-based programs (OR=0.79, 95% CI=0.75-0.83), programs by trained teachers or educators (OR=0.77, 95% CI=0.71-0.83), high-intensity programs (OR=0.82, 95% CI=0.75-0.91), and programs in an in-school setting (OR=0.82, 95% CI=0.74-0.90) had the most significant effect on reducing smoking behavior. CONCLUSION: For young adolescents, smoking prevention programs are most effective when they are school-based or highintensity programs, and when conducted by teachers or educators with proper training. Further studies are required since there was insufficient research to explore the effect of web-based programs or family-centered programs on adolescent smokers.

Effect of goal attainment theory based education program on cardiovascular risks, behavioral modification, and quality of life among patients with first episode of acute myocardial infarction: Randomized study.

Effect of goal-attainment-theory-based education program on cardiovascular risks, behavioral modification, and quality of life among patients with first episode of acute myocardial infarction: randomized study BACKGROUND: The behavioral modification strategies should be explored at the time of admission to lead the maximum effect of cardiovascular risk management. AIMS: This randomized study aimed to elucidate the effects of a nurse-led theory-based education program in individuals with a first episode of acute myocardial infarction on cardiovascular risks, health behaviors, and quality of life over 6 months. METHODS: The study involved a convenience sample of 64 patients with acute myocardial infarction who were randomly assigned to either the education group or the control group. The goal-attainment-based education program was designed to set the mutually agreed goals of risk management and the behavioral modification strategies for achieving those goals. Those in the control group received routine management only. The participants in both groups were contacted at 6-8 weeks and at 6 months after discharge to measure outcome variables. Repeated measure ANOVA was conducted using SPSSWIN (version 20.0) to determine the significance of differences in outcome variables over 6 months between the groups. RESULTS: Both groups showed significant positive changes in cardiovascular risks, health behaviors, and quality of life over 6 months. The 2-year risk of cardiovascular disease was significantly reduced in both study groups, but with no significant interaction effect (F=2.01, p=0.142). The performance and maintenance of health behaviors (F=3.75, p=0.029) and the mental component of quality of life (F=4.03, p=0.020) were significantly better in the education group than the control group. CONCLUSION: Applying a goal-oriented education program at an early stage of hospital management improved and maintained blood glucose, health behaviors, and mental component of the quality of life up to six months in individuals with a first episode of myocardial infarction. Further studies are warranted to explore the role of behavioral modification mediating between cardiovascular risk management and quality of life in this population.

Effects of t'ai chi on balance: a population-based meta-analysis.

OBJECTIVE: To systematically review and analyze the effects of t'ai chi on balance in older adults. METHODS: The literature was searched for randomized clinical trials on the effects of t'ai chi on balance, as evaluated by direct, static, dynamic, and mixed measures. The effect sizes (ESs) on balance were calculated by using the standardized mean difference (d) and 95% confidence intervals. RESULTS: Thirty-four studies were included. The overall ES of t'ai chi on static balance was medium at 3 months (ES=0.73) and small at 6 months (ES=0.33) for participants with a low risk of falling. For those with a high risk of falling, the ES of t'ai chi on static balance was small (ES=0.47) at 3 months but not significant at 6 months. When compared with the no-exercise group, the ES of t'ai chi on static balance was medium (ES=0.66) at 3 months but smaller at 6 months (ES=0.37). The ES of t'ai chi (ES=0.31) was only significant at 6 months when compared with other exercise. CONCLUSION: The findings of this meta-analysis suggest that persons with a low risk of falling should practice t'ai chi for 3 months to improve their balance. The effects of t'ai chi on balance in those with a high risk of falling were small but significant at 3 months, supporting the safety and effectiveness of t'ai chi. It is important to select reliable and sensitive measures for balance to examine the effects of t'ai chi.

[Effects of Tai Chi on fall risk factors: a meta-analysis].

PURPOSE: This study was done to analyze the effects of Tai Chi on fall-related risk factors through meta-analysis of randomized clinical trials published in English and Korean between 2000 and 2010. METHODS: Using health related database and hand search of references and Google, 28 randomized studies were collected from doctoral dissertation and published peer reviewed articles. The Comprehensive Meta-analysis version 2.0 was used for the analysis. RESULTS: The effect sizes for Tai Chi for 3 months were significant with ES=0.54 for static balance, ES=0.24 for dynamic balance, ES=0.69 for balance measured by scale, and ES=0.40 for flexibility, ES=0.48 for muscle strength, ES=0.71 for ADL, and ES=0.37 for fear of falling. Also, the effect sizes of Tai Chi for 6 months were significant for most fall-related variables. The 6 month data for flexibility was not analyzed since only one study was published. CONCLUSION: The analysis of studies of randomized clinical trials indicate that Tai Chi is effective in improving balance, flexibility, muscle strength, activities of daily living, and fear of falling when applied for 3 or 6 months. The findings provide the objective evidence to apply Tai Chi as a fall preventive intervention.
