Gender differences in related influential factors of regular exercise behavior among people in Taiwan in 2007: A cross-sectional study

Dose-response relationship between weekly physical activity level and the frequency of colds in Chinese middle-aged and elderly individuals

Background

Engaging in appropriate physical activity can significantly lower the risk of various diseases among middle-aged and older adults. Investigating optimal levels of physical activity (PA) is crucial for enhancing the health of this demographic. This study aims to explore the dose-response relationship between weekly PA levels and the frequency of colds among Chinese middle-aged and elderly individuals, identifying the necessary PA level to effectively diminish the risk of colds.

Methods

We conducted a cross-sectional study using a web-based survey targeting individuals aged 40 and older (n = 1, 683) in China. The survey collected information on PA and the frequency of colds. Data was analyzed using Kruskal-Wallis test and the χ2 test. We explored the dose-response relationship between weekly PA and cold frequency over the past year through an ordered multivariate logistic regression model and a restricted cubic spline model.

Results

(1) Brisk walking emerged as the preferred physical exercise for those over 40. The findings suggest that engaging in moderate (odds ratio (OR) = 0.64, P < 0.001, 95% confidence interval (CI) [0.50-0.81]) and high (OR = 0.64, P < 0.001, 95% CI [0.51-0.79]) levels of PA weekly significantly reduces the risk of catching a cold. Individuals with one (OR = 1.47, P < 0.001, 95% CI [1.20-1.80]) or multiple chronic diseases (OR = 1.56, P < 0.001, 95% CI [1.21-2.00]) were at increased risk. Those residing in central (OR = 1.64, P < 0.001, 95% CI [1.33-02.01]) and western China (OR = 1.49, P = 0.008, 95% CI [1.11-02.00]) faced a higher risk compared to their counterparts in eastern China. (2) According to the restricted cubic spline model, adults who experienced one cold in the past year had a weekly PA level of 537.29 metabolic equivalent-minutes per week (MET-min/wk) with an OR value of 1. For those reporting two or more colds, the PA level was 537.76 MET-min/wk with an OR of 1.

Conclusions

(1) Brisk walking is the most favored exercise among the Chinese middle-aged and elderly, with the prevalence of colds being affected by the number of chronic diseases and the geographic location. (2) Regular, moderate exercise is linked to a lower risk of colds. To effectively reduce cold frequency, it is recommended that middle-aged and elderly Chinese individuals engage in a minimum of 538 MET-min/wk of exercise.

Understanding physical exercise among individuals with substance use disorders using an integrated theoretical perspective of the health action process approach and theory of planned behavior

Introduction

Physical exercise is considered a useful non-pharmacological adjunctive treatment for promoting recovery from substance use disorders (SUD). However, adherence to physical exercise treatments is low, and little is known about what factors are associated with the initiation and maintenance of physical exercise behaviors. The aim of this study was to explore the psychosocial factors underlying these behaviors in individuals with SUD using an integrated theoretical model based on the health action process approach (HAPA) and the theory of planned behavior (TPB).

Methods

A total of 1,197 individuals with SUDs (aged 37.20 ± 8.62 years) were recruited from 10 compulsory isolation drug rehabilitation centers in Zhejiang Province via convenience sampling according to a set of inclusion criteria. Self-reported data were collected to assess task self-efficacy (TSE), maintenance self-efficacy (MSE), recovery self-efficacy (RSE), outcome expectations (OE), action planning (AP), coping planning (CP), social support (SS), subjective norms (SN), attitude behavior (AB), behavioral intention (BI), perceived behavioral control (PBC), risk perception (RP), exercise stage, and exercise behavior in this integrated model. ANOVA and structural equation modeling (SEM) were used to evaluate this model.

Results

One-way ANOVA revealed that the majority of the moderating variables were significantly different in the exercise phase. Further SEM showed that the model fit the data and revealed several important relationships. TSE, RP, SS, AB, and SN were indirectly associated with physical exercise behavior in individuals with SUD through the BI in the SUD initiation stage. In addition, PBC was directly related to physical exercise behavior in individuals with SUD. In the maintenance stage, MSE, AP, CP and exercise behavior were significantly related. Moreover, AP and CP were mediators of BI and MSE.

Conclusion

This study is the first attempt to integrate patterns of physical exercise behavior in individuals with SUD. The HAPA-TPB integration model provides a useful framework for identifying determinants of physical exercise behavioral intentions and behaviors in individuals with SUD and for explaining and predicting the initiation and maintenance of physical exercise behaviors in these individuals. Moreover, the model provides scientific guidance for the enhancement of physical exercise adherence in individuals with SUD.

Developing and evaluating a mindfulness-based finger/hand exercise intervention for ethnically diverse older adults with and without disabilities: A feasibility study

Few exercise interventions target ethnic minority older adults, especially those with disability. We evaluated feasibility of newly-developed finger/hand exercises to promote health in ethnically diverse older adults with/without disability. We conducted 10-minute video exercises daily, supervised by research assistants. The feasibility, evaluated via three studies, focused on recruitment, intervention fidelity, safety, outcome assessment, and acceptability. Studies varied in design and delivery methods, being conducted across settings (senior centers, apartments). We enrolled 101 Chinese older adults (mean age = 72) without disability in Study 1, and 15 older Africans/Hispanics with disability (mean age = 70) in Studies 2 and 3. Intervention, either in-person or online, was implementable and acceptable with high fidelity. Attendance was satisfactory (79.6%, 74.2%, 76.7%) and attrition was low (12%, 0%, 0%). Outcome measures data was ascertained. No adverse events were observed. Preliminary findings indicate feasibility, acceptability, and safety of the simple finger/hand exercise for diverse older adults.

Exploring the experiences of an exercise-based telerehabilitation program among Canadian community-dwelling adults with stroke

PURPOSE

Telerehabilitation is emerging as a means for delivering stroke rehabilitation to address unmet lower extremity rehabilitation needs. However, there is currently limited and low-quality evidence supporting the use telerehabilitation interventions for lower extremity recovery after stroke. Thus, we developed an exercise-based telerehabilitation program (TRAIL) for safe and effective promotion of lower extremity function after stroke. This study reports on the qualitative findings from the feasibility study of the TRAIL program.

METHODS

An interpretive description methodology and inductive thematic analysis approach were undertaken. One-on-one semi-structured interviews were conducted on a subset of participants who completed the TRAIL feasibility study. Participants were recruited via email and enrolled into the study based on pre-determined purposeful sampling strategies.

RESULTS

Ten participants (6 men, 4 women) completed a semi-structured interview. Two main themes emerged: (i) TRAIL ingredients for success and (ii) telerehabilitation is a viable option for stroke rehabilitation.

CONCLUSION

Exercise-based telerehabilitation appears to be well-received by men and women post-stroke when social support, professional guidance, and program resources are offered. TRAIL may also prolong the continuum of care that individuals receive once they are discharged back into the community, and contribute to improvements in mobility, lower extremity strength and balance.

Differences in the purpose of exercise between hemodialysis patients who continued or dropped out of exercise programs: a multicenter cohort study

BACKGROUND

Selecting suitable exercise goals is crucial for fostering adherence to, and maintenance of, exercise therapy. We aimed to evaluate the variance in exercise objectives between individuals who continued and those who dropped out of a 6-month intradialytic exercise program by analyzing an open-ended questionnaire administered to patients undergoing hemodialysis.

METHODS

The study consisted of outpatients (n = 541; mean age, 70 years) undergoing maintenance hemodialysis, who had been informed of an intradialytic exercise program and voluntarily agreed to participate. The primary outcome was the exercise purpose. The difference in exercise purpose was quantitatively analyzed between the exercise continuation and dropout groups. A co-occurrence network was created and concepts were constructed. The basic attributes were compared using chi-squared and independent t-tests.

RESULTS

Over 6 months, 154 patients (28.5%) dropped out of the intradialytic exercise program. Concepts related to the goals of the program were: (1) physical function and condition, (2) addressing limitations, (3) maintaining daily life activities, and (4) physical condition recognition. Co-occurrence network analysis showed that the exercise continuation group established their objectives based on the health benefits of exercise, and proactively set goals rooted in comprehending their current issues and problems. The dropout group tended to perceive treatment passively as an extension of daily clinical practice, rather than actively formulating exercise objectives.

CONCLUSION

The exercise objectives of those who continued the exercise program differed from those who dropped out. Patients in the exercise continuation group set more affirmative and specific exercise objectives, whereas those in the dropout group set more passive and abstract exercise objectives.

Effect of Autonomy and Physical Activity on Self-Rated Health of Older Adults in India: Gendered Analysis Using Structural Equation Models

The gendered expectations and responsibilities placed upon women can impede their ability to participate in social activities and engage in physical leisure pursuits, ultimately having a negative impact on their health. Our study investigates the mechanisms through which gender influences individuals' engagement with physical activity during free time and how this relates to self-rated health outcomes among adults aged 45 years or older living in India. Using cross-sectional analysis and Structural Equation Modelling, we analyzed data stratified by gender and age from the Longitudinal Ageing Study of India to examine these conceptual pathways. We found that compared to men, women face greater limitations related to decision-making autonomy, experience more functional impairments, have weaker social networks that provide less support for engaging in leisure-time physical activity, leading them to report lower levels of overall wellbeing than men. Further analyses demonstrated distinct pathways through which each gender's level of social network connectivity shapes behavior - strong connections increase opportunities for women specifically to engage positively with both peers and physically active pursuits supporting overall wellness goals.

Association of Physical Activity with Total and Cause-specific Mortality in Patients with Diabetes: A Nationwide Population-based Cohort Study

AIMS

Physical inactivity is a modifiable risk factor for cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM); however, little is known about its association with mortality due to other causes. Herein, we investigated the association between physical activity (PA) and cause-specific mortality in patients with T2DM.

METHODS

We analyzed data from the Korean National Health Insurance Service and claims database of adults with T2DM aged >20 years at baseline (n=2,651,214). Each participant's PA volume was measured as the metabolic equivalent of tasks (METs)-min per week, and hazard ratios of all-cause and cause-specific mortality relative to PA levels were estimated.

RESULTS

During the 7.8 years of follow-up, all-cause, CVD, respiratory, cancer, and other causes of mortality were lowest in patients engaged in vigorous PA. MET-min/week was inversely associated with mortality after adjusting for covariates. The reduction in total and cause-specific mortality was greater in patients aged ≥65 years than in those aged <65 years.

CONCLUSIONS

Increasing PA may facilitate a reduction in mortality from various causes, especially among older patients with T2DM. Clinicians should encourage such patients to increase their daily PA levels to reduce their risk of mortality.

Culturally tailored group Qigong exercise in older Chinese immigrants: A feasibility study

BACKGROUND

Culturally tailored group exercise bridges health disparities among new immigrants, particularly older adults. We designed a Chinese Qigong (Baduanjin) exercise intervention testing the feasibility and acceptability among older Chinese at a senior daycare center in Philadelphia, PA, US.

METHODS

10-week Qigong group in-person exercise was delivered 5 days a week, using a 12-minute video tutorial under trained research assistants' guidance. Daily attendance and attrition was recorded. Participants completed baseline self-report assessments on physical and mental health, and two computerized cognitive tests, the psychomotor vigilance test and a memory test.

RESULTS

53 older adults participated (mean age: 78, female: 88.7%). Average daily attendance was 65.28%. Stratification analysis on age groups <80 and ≥80 shows no significant differences on key variables.

CONCLUSIONS

Recruitment for Baduanjin Qigong exercise was feasible in senior daycare centers, and older adults could easily learn and safely follow exercise movements. Preliminarily findings call for further research.

Physical Activity among Rural Residents in Eastern, Central, and Western Provinces of China: A Cross-Sectional Survey

Physical activity (PA) in which physical exercise (PE) is an important component is probably the most important intervention for preventing noncommunicable diseases (NCDs). However, few studies on PA and PE of rural residents in China were reported. This study conducted the first population-based cross-sectional survey in three provinces of China in 2021 that examined both PA and PE as well as the associated factors of rural residents. The International Physical Activity Questionnaire Short Form (IPAQ-S) was used, and a total of 3780 rural residents were surveyed. The result showed that 22.2% of the rural residents were physical inactivity and rural residents reporting practice of PE was 54.4%. Binary logistic regression analyses showed that being female, people aged between 15 to 34 years or 60 years old and above, employees of governmental departments/retirees, school students, the unemployed, and people with NCDs were risk factors of PA while ethnic minority groups, smoking, and alcohol consumption were risk factors of PE. Health promotion programme aiming at increasing people's PA in rural China is urgently needed, and it should focus on the population groups of the female, people aged 60 years and above, school students, the unemployed, and people with NCDs.

Sex differences in the change of exercise behavior leading to incident metabolic syndrome reduction: A community-based prospective study

This study was undertaken to assess the role of sex differences in the effects of exercise behavior change on incident metabolic syndrome (MetS) in Changhua County, Taiwan. Using data derived from the Changhua Community-based Integrated Screening (CHCIS), 22,594 eligible residents aged 40 years or older had the screening at least twice from 2005 to 2018. A prospective cohort study was designed to follow up the normal cohort without MetS at baseline to ascertain incident MetS in the light of the criteria of the Epidemiology Task Force Consensus Group. We then evaluated whether there was a sex difference in the outcome of incident MetS attributed to the change in exercise behavior from three (no, irregular, and regular exercise) maintained patterns already defined at baseline to either the enhanced pattern or the reduced pattern by the end of follow-up. We applied Cox proportional hazards regression model stratified by sex for estimating the hazard ratio of any two-group comparison. After adjustment for sociodemographic factors, the number of screenings attended, personal disease history, and other health behaviors, the influence of change in exercise behavior on incident MetS was statistically significant only in men. Specifically, maintaining no exercise showed a lower risk of MetS than maintaining regular exercise 21 % in men. Regarding the change in exercise behavior, men with the enhanced pattern reduced the risk of MetS by 15 % compared with those maintaining regular exercise. The findings suggest that positive changes in exercise behavior reduce the incidence of MetS in men but not in women.

Physical Activity and Social Support to Promote a Health-Promoting Lifestyle in Older Adults: An Intervention Study

The purpose of this study was to understand the effect of intervention in the form of physical activity and social support while co-exercising to promote a health-promoting lifestyle in older adults. This study openly recruited 60 healthy male older adults, all of whom wore a wrist-worn Garmin device walker. Experimental group A was monitored by a special person and walked together as a group, experimental group B walked independently outdoors, and the control group went about their daily routine as normal. All participants recorded daily steps and calorie consumption data for eight weeks. The results of the study showed that when walking together in experimental group A, the number of daily walks and calories consumed could be maintained at a high level due to the effect of group and social support. The number of daily walks in experimental group B was inconsistent due to the lack of motivation to walk on their own. The control group consumed the lowest number of calories in their daily routine. The results show that physical activity and social support have positive explanatory power for a health-promoting lifestyle. Finally, physical activity in older adults should be promoted, and social support for interaction with peers can effectively promote a healthy lifestyle and respond to the arrival of the super-aged society in advance.

Significantly different roles of economic affluence in sex-specific obesity prevalence rates: understanding more modifications within female body weight management

Socioeconomic status has been associated with obesity prevalence increase in both males and females worldwide. We examined the magnitude of the difference between the two relationships and explored the independence of both relationships. Country specific data on gross domestic product (GDP) per capita, sex-specific obesity prevalence rates, urbanisation, total calories availability and level of obesity, genetic background accumulation (measured by the Biological State Index, I_bs) were obtained for 191 countries. Curvilinear regressions, bivariate and partial correlations, linear mixed models and multivariate linear regression analyses were used to examine the relationship between GDP and obesity prevalence rates in males and females respectively. Fisher’s r-to-z transformation, F-test and R² increment in multivariate regression were used to compare results for males and females. GDP significantly correlated with sex-specific obesity prevalence rates, but significantly more strongly with male obesity prevalence in bivariate correlation analyses. These relationships remained independent of calories availability, I_bs and urbanization in partial correlation model. Stepwise multiple regression identified that GDP was a significant predictor of obesity prevalence in both sexes. Multivariate stepwise regression showed that, when adding GDP as an obesity prevalence predictor, the absolute increment of R² in male fit model (0.046) was almost four (4) times greater than the absolute increment in female model fit (0.012). The Stepwise analyses also revealed that 68.0% of male but only 37.4% of female obesity prevalence rates were explained by the total contributing effects of GDP, I_bs, urbanization and calories availability. In both Pearson’s r and nonparametric analyses, GDP contributes significantly more to male obesity than to female obesity in both developed and developing countries. GDP also determined the significant regional variation in male, but not female obesity prevalence. GDP may contribute to obesity prevalence significantly more in males than in females regardless of the confounding effects of I_bs, urbanization and calories. This may suggest that aetiologies for female obesity are much more complex than for males and more confounders should be included in the future studies when data are available.

Psychometric Validation of Senior Perceived Physical Literacy Instrument

Aim: To validate the Senior Perceived Physical Literacy Instrument (SPPLI). Methods: In the pilot study, we refined the Perceived Physical Literacy Instrument (PPLI, Cronbach’s α = 0.94, initially designed for adults) into SPPLI using internal reliability, content validity, and construct validity results. A total of 341 older adults recruited from community centers in Southern Taiwan participated in the study. A principle component analysis (PCA) identified three components of SPPLI. Results: Eleven items were captured from the 18-item PPLI as the SPPLI (Cronbach’s α = 0.90). SPPLI exhibits three components: attitude toward physical activity, physical activity ability, and sociality around physical activity. Significant differences were discovered in physical activity ability by educational attainment (p < 0.05) and in all three components by stage of exercise (maintenance vs. non-maintenance) (p < 0.05). The SPPLI possesses proper reliability and validity to assess physical literacy among older adults. Conclusions: This instrument is suggested for physical literacy assessments in physical activity programs to assess the needs of older adults and/or the effectiveness of an intervention program that aims to improve the attitude, ability, and sociality of physical activity.

Regular Physical Activities Inhibit Risk Factors of the Common Cold Among Chinese Adults

Background

Physical activity (PA) has a significant health impact worldwide and has been linked to a lower risk of the common cold.

Objective

The aim of this study was to estimate the form of PA among Chinese adults and the correlation between PA and number of the common cold in China's eastern, central, and western areas.

Design

A cross-sectional study.

Setting

China's eastern, central, and western regions from 30 November 2020 to 30 March 2021.

Patients

A total of 1,920 healthy participants, who aged over 18 years old, with Internet access, were enrolled, and then self-reported PA behaviors and number of the common cold were collected.

Measurements

The authors calculated preference, intensity, frequency, and duration of PA in Chinese based on gender, age, and broad occupational categories and explored the potential effect between these factors and the common cold.

Results

Approximately 20.4% of participants reported not participating in sports regularly. Except for gender, there were significant differences in PA preference and intensity among the remaining individuals (P <0.05). Sixteen common exercises were divided into three intensity levels by the Borg CR10 Scale: low- (5), moderate- (8), and high-intensity exercises (3), and the corresponding intensity, frequency, and duration were computed with significant differences (P <0.05). The most popular workouts are “Brisk walking” and “Running.” Age, sex, and occupation had no significant effect on colds (P > 0.05). However, intensity shows a U-shaped dose-response relationship with colds, whereas the frequency and duration have an inverse dose-response relationship (P <0.05). High intensity combined with high frequency increased colds the most. Nevertheless, non-exercise groups always have the most colds in each comparison.

Limitations

The result may be vulnerable to recall bias.

Conclusion

Intensity showed that U-shape, frequency, and duration showed inverse response to the number of colds last year, but age, sex, and occupation had no significant effects. High intensity and high frequency mixed increased colds the most, regardless of duration.

Interactions between parental and personal socioeconomic resources and self-rated health: Adjudicating between the resource substitution and resource multiplication theories

A small body of research has documented intriguing findings, mostly from the United States but also from Europe, which suggest that the positive health effects of socioeconomic resources in adulthood may be conditioned by socioeconomic circumstances in childhood. There are two competing theories in this literature. The first contends that socioeconomic resources have a stronger effect on adult health for people from disadvantaged backgrounds because socioeconomic resources in adulthood substitute or compensate for a paucity of health-related resources earlier in life. The second contends that socioeconomic resources have a stronger effect on adult health for people from advantaged backgrounds because socioeconomic resources in adulthood compound or multiply the health effects of socioeconomic resources earlier in life. We used survey data from the 2012 Longitudinal and International Study of Adults linked to current and historical income data from the Canada Revenue Agency to investigate interactions between parental and personal socioeconomic resources - education and income, treated separately - as predictors of self-rated health in a sample of Canadians aged 25 to 50. Consistent with the resource multiplication theory, we found that the presumed benefits of personal family income for self-rated health were stronger for women from wealthier backgrounds than for women from poorer backgrounds. We found no evidence to support either theory among men. Overall, none of the interactions involving the education of parents or their adult children reached statistical significance. Our results are indicative of the importance of distinguishing between education and income for adults and their parents when adjudicating between these two theories.

Predict the exercise behavior intention of the older adults in Taipei City to promote exercise behavior

The purpose of this study employed the theory of planned behavior as a research framework to analyze the explanatory power of exercise attitude, subjective norms, and perceived behavioral control on exercise intention among older adults and to obtain insight on exercise behavior among older adults. The study used Ajzen's theory of planning behavior as a basis to compile the "Exercise Behavior Intention Questionnaire of the Older Adults." Results showed that there were significant differences were detected in the exercise intentions of older adults with different subjective norms and perceived behavioral control. This indicated that older adults of greater age have a greater need for companionship from family members and stronger subjective norms. In addition, exercise attitude, subjective norms, and perceived behavioral control explained the variance in exercise intention among older adults, verifying the positive explanatory power of these variables on exercise intention in older adults. The study concluded that the theory of planned behavior, improving older adults' exercise attitude alone was insufficient for increasing their exercise behavior intention. In particular, older adults of greater age had greater needs for social support from the main groups, and they required encouragement to enhance their self-efficacy and confidence.

Prospective associations of different contexts of physical activity with psychological distress and well-being among middle-aged adults: An analysis of the 1970 British Cohort Study

BACKGROUND

Our aim was to investigate whether different types and social contexts of physical activity (PA) participation are prospectively associated with psychological distress and well-being among middle-aged adults.

METHODS

Data from the 1970 British Cohort Study was used (N = 5144-2733 women). At age 42y, participants reported their type of leisure-time PA, which was classified as individual PA or group PA (exposure). At age 46y, participants reported co-primary outcomes: psychological distress (Malaise Inventory) and well-being (Warwick-Edinburgh scale). Highest academic achievement, employment status, country of interview, baseline values of psychological distress and well-being, smoking, alcohol use, TV-viewing and total physical activity at 42y were used as covariates. Main analyses included linear regression stratifying by sex.

RESULTS

Jogging, cross-country, road-running (both sexes) as well as team sports (men) were associated with higher well-being. Health, fitness, gym or conditioning activities and jogging, cross-country (women), road-running (women) and team sports (men) were associated with lower psychological distress. Participation in both individual and group PA were associated with lower psychological distress and higher well-being for both sexes in crude models. However, adjusted models revealed that only group PA was associated with lower psychological distress (B: -0.106; 95%CI: -0.188 to -0.025) and higher well-being (0.835; 0.050 to 1.619) among men but not women. In the sensitivity analysis, group PA was associated with higher well-being (0.855; 0.094 to 1.616) when compared with individual PA among men. Group PA was not associated with psychological distress among both sexes and well-being among women when compared with individual PA.

CONCLUSION

Group PA was prospectively associated with lower psychological distress and higher well-being among men but not females. Future PA interventions could focus on group activities for males. Further research to understand the relationship between individual/group PA and mental health is required in females.

Have We Taken Advantage of the Quarantine to Develop Healthy Habits? A Cross-Sectional Analysis of the Spanish COVID-19 Situation by Gender

The confinement caused by the COVID-19 pandemic led to changes in people’s lifestyles, which in part provided an opportunity to develop habits at home. The aims were: (1) to verify if the psychological well-being (PWB) of people related to healthy habits, and if physical activity (PA) and diet mediated this relationship; (2) to test if there were differences in this model of relationships between women and men; (3) to analyze if there were differences in healthy habits, PA, diet, and PWB depending on gender; (4) to test if there were differences in healthy habits, PA, diet, and PWB depending on living area; (5) and to assess if there were interaction effects of gender and living area in healthy habits, PA, diet, and PWB. Using a cross-sectional design, we obtained a sample of 1509 participants (18–78 years, 1020 women). Diet and PA fully mediated the relationship between PWB and healthy habits, and women developed more healthy habits than men, whereas men had higher levels of PA and PWB. We also found that people who lived in rural areas during confinement practiced more PA and had lower PWB levels than those who lived in urban areas. These results can help in the planning of strategies to promote healthy habits.

Network of biomarkers and their mediation effects on the associations between regular exercise and the incidence of cardiovascular & metabolic diseases

This study aimed to understand the biological process related to the prevention of cardiovascular & metabolic diseases (CMD), including diabetes, hypertension, and dyslipidemia via regular exercise. This study included 17,053 subjects aged 40–69 years in the Health Examinees Study from 2004 to 2012. Participation in regular exercise was investigated by questionnaires. Data on 42 biomarkers were collected from anthropometric measures and laboratory tests. We examined the associations between regular exercise and biomarkers using general linear models, between biomarkers and the risk of CMD using cox proportional hazard models, and the mediation effect of biomarkers using mediation analyses. Biomarker networks were constructed based on the significant differential correlations (p < 0.05) between the exercise and non-exercise groups in men and women, respectively. We observed significant mediators in 14 and 16 of the biomarkers in men and women, respectively. Triglyceride level was a noteworthy mediator in decreasing the risk of CMD with exercise, explaining 23.79% in men and 58.20% in women. The biomarker network showed comprehensive relationships and associations among exercise, biomarkers, and CMD. Body composition-related biomarkers were likely to play major roles in men, while obesity-related biomarkers seemed to be key factors in women.

Factors Affecting the Intention to Modify Lifestyle in the Cardiovascular Disease Risk Group in Korea

This study aimed to identify people at risk of cardiovascular diseases (CVD) using the Framingham risk score (FRS) and to examine their willingness to modify their lifestyle. A descriptive correlational study with 1229 participants, aged 30-74 years, without cardiovascular or cerebrovascular diseases who visited a health examination center in South Korea was conducted. Of 1229 participants, 455 were identified as high risk for CVD with an FRS of 10 or higher. A logistic regression analysis confirmed age, sex, muscle training, and weekly drinking frequency as predictors of intention to quit smoking; age, smoking, and waist to height ratio (WHtR) as predictors of intention to quit drinking; sex and WHtR as predictors of intention to engage in physical exercise; and hypertension and body mass index as predictors of intention of muscle training. People at high risk for CVD lack willingness to modify their lifestyle, and aggressive, customized intervention is needed to promote lifestyle modification.

The Development Strategy of Home-Based Exercise in China Based on the SWOT-AHP Model

In view of the increasing importance of sports to people and the impact of COVID-19 on people’s lives, home-based exercise has become a popular choice for people to keep fit due to its unique advantages and its popularity is expected to keep growing in the future. Therefore, it is necessary to determine the development direction of home-based exercise and put in the corresponding efforts. However, there is currently a lack of research on all aspects of home-based exercise. The purpose of this research was to investigate the effective sustainable development strategy of home-based exercise in China through a SWOT (Strengths, Weaknesses, Opportunities and Threats) and AHP (Analytic Hierarchy Process) hybrid model. Thirteen factors corresponding to the SWOT analysis were identified through a literature review and expert opinions. The results show that in China the advantages and potential outweigh the weaknesses and threats of home-based exercise. Home-based exercise should grasp the external development opportunities and choose the SO development strategic type that combines internal strengths and external opportunities. As the core for the development of home-based exercise, this strategy should be given priority. To sum up, home-based exercise is believed to have a bright future.

Knowledge, attitudes and practices of hospital-based staff regarding physical activity at a private hospital in Johannesburg

Background

Physical activity has been established as an important component to incorporate into a healthy lifestyle. Hospital-based staff are also threatened by the risks of sedentary lifestyles, despite their association with a healthcare environment. The aim of this study was to determine the knowledge, attitudes and practices of private hospital-based staff regarding physical activity in Johannesburg.

Methods

A cross-sectional study was conducted. Data were collected using a self-administered questionnaire. Data were analysed with a combination of descriptive and inferential statistics. A p-value less than 0.05 was deemed statistically significant.

Results

A total number of 217 participants responded to the questionnaire. The majority of participants (n = 179; 82.49%) displayed excellent knowledge of physical activity, had a good attitude towards physical activity (n = 157; 72.35%) and displayed satisfactory practices (n = 137; 63.13%). Participants with the highest level of education had better mean knowledge, attitude and practice scores as opposed to those with lower levels of education. There was a statistically significant difference amongst staff categories in terms of knowledge (p = 0.004) and practice scores (p = 0.031). In addition, there was a statistically significant difference amongst different levels of education in terms of knowledge (p = 0.000), attitude (p = 0.02) and practice scores (p = 0.004).

Conclusion

Staff members who participated in the study displayed only satisfactory physical activity practices. The hospital’s employee wellness programme should establish appropriate strategies to improve staff practices of physical activity in order to promote health.

Physical exercise among radiologists in Saudi Arabia: a cross-sectional study

Background

The practice of clinical radiology has become more sedentary in the era of the Picture Archiving and Communication System. Physical inactivity is a well-known risk factor for various chronic diseases. This study aimed to determine the frequency and pattern of physical exercises among radiologists in the Eastern Province of Saudi Arabia and the association between physical exercises and the prevalence of work-related musculoskeletal symptoms.

Methods

An online survey was sent to radiologists in all hospitals (academic, public, and private) in the major cities of the Eastern Province of Saudi Arabia. It covered information about demographic characteristics and the frequency and pattern of physical exercises. It also included an evaluation of work-related musculoskeletal symptoms using the Nordic Musculoskeletal Questionnaire. This survey of 263 radiologists was conducted in April 2019. The study outcome was the presence of disabling musculoskeletal symptoms in any body region which restricted the performance of normal activities within the last 12 months. The study results were analyzed descriptively using the Chi-square test.

Results

The survey was completed by 198 participants (111 men and 87 women) with a response rate of 75.3%. Most participants (71.2%) were less than 40 years. Eighty-three men (74.8%) did a physical exercise at least weekly, compared to 45 (51.7%) women. Men were more likely to engage in various physical exercises than women. Overall, 60.9% of participants who did not do any physical exercise regularly (less than monthly) reported having disabling neck pain. This figure was found lower among participants who did physical exercises monthly (45.8%) or at least weekly (32.8%). A similar pattern was observed with shoulder pain, with 45.7% found in participants who did not exercise and only 25.8% in those engaging in physical activities at least weekly.

Conclusions

Physical inactivity is common among radiologists, especially female ones, in the Eastern Province of Saudi Arabia. The physical inactivity was significantly associated with work-related musculoskeletal symptoms. Gender-specific health promotion programs are needed to mitigate the negative health outcomes due to the sedentary nature of the radiology current practice.

The Relationship between Health Consciousness and Home-Based Exercise in China during the COVID-19 Pandemic

During the COVID-19 pandemic, people have reduced the frequency of going out, and need to engage in health behaviors at home. Home-based exercise has aroused people's attention. This paper aims to examine the influencing mechanism of health consciousness on home-based exercise during the COVID-19 pandemic. A questionnaire method was used to select 449 Chinese respondents on an online platform; the questionnaire includes a health consciousness scale, health life goal scale, perceived behavioral control scale, and the home-based exercise scale. A T-test was used to conduct differential analysis. The hierarchical regression analysis method was used to examine the relationship between health consciousness and home-based exercise, and the Hayes' SPSS PROCESS macro was used to test mediating effect. The results show that there are significant differences in home-based exercise with respect to gender, age, and marital status. Health consciousness has a significant positive effect on home-based exercise. Perceived behavioral control acts as the mediator between health consciousness and home-based exercise. Health consciousness can influence home-based exercise through health life goals and perceived behavioral control in turn. This paper takes a home-based exercise survey, and expands the theoretical research of home-based exercise. The findings suggest that people should pay attention to promoting the transformation of health consciousness into home-based exercise. It provides enlightenment for people to adopt health behaviors during the COVID-19 pandemic.
