The impact of social capital on physical activity and nutrition in China: the mediating effect of health literacy

Structural relationship of the social-ecological factors and psychological factors on physical activity

The present study examines the mediating effect of psychological factors in the structural relationships between social and physical environmental factors and the amount of physical activity among undergraduate students at Universiti Sains Malaysia. The sample consisted of 422 students with a mean age of 20.2 years (SD = 1.27). The majority of the students were female (69.7%) and Malay (81.3%). Standardized scales were used to measure the total amount of physical activity and all the study variables. The final SEM had a good fit to the data: CFI = 0.968, TLI = 0.948, SRMR = 0.036, RMSEA (90%CI) = 0.046 (0.025, 0.065), RMSEA p-value = 0.609 with 11 paths relationships. Family support had a significant effect on perceived benefits and perceived barriers. The effect of friend support on physical activity was significantly mediated by perceived benefits, self-efficacy, and psychological needs satisfaction. The effect of the availability of exercise facilities on physical activity was significantly mediated by perceived benefits and psychological needs satisfaction. Furthermore, psychological needs satisfaction mediated the effect of perceived benefits, perceived barriers, and self-efficacy on physical activity. The study findings illustrated that the application of the social-ecological model and psychological factors is important in order to understand and promote positive physical activity behaviour.

Causal Model of Herb Use Behavior Among Working-age Adults in Thailand

OBJECTIVES

This study developed a causal relationship model of herb use from observational data and analyzed the direct and indirect effects of herb use on health according to the model.

METHODS

A cross-sectional study was conducted with 400 participants aged 26-59 years, selected through multistage random sampling. The instruments used for data collection included demographic information, herb use, health literacy (HL), perceived social support, societal values, and attitudes toward herb use. The conceptual model, hypothesized based on prior evidence, was tested using confirmatory factor analysis through structural equation modeling. Path coefficients were estimated using the maximum likelihood method.

RESULTS

The final model utilized empirical data, which showed that perceived social support had the most significant impact on herb use. This was followed by HL, positive attitudes toward herbal remedies, and societal values, with coefficients of 0.31, 0.18, and 0.16, respectively. When analyzing variables that indirectly affected herb use, it was clear that positive attitudes, perceived social support, and societal values significantly influenced herb use through HL, with influence coefficients of 0.08, 0.16, and 0.04, respectively. Together, these variables accounted for 68% of the variance in herb use.

CONCLUSIONS

The findings from this study can be utilized to develop and implement strategies that guide the use of herbal products, ultimately aiming to improve human health.

Social capital and healthy eating among two ethnic minority groups in Yunnan Province, Southwest China: the mediating role of social support and nutrition knowledge

Background

Although social capital has been linked to dietary intake particularly in disadvantaged populations, little is known about the mechanisms. This study aimed to investigate whether social support (SS) and nutrition knowledge (NK) mediate the association between social capital and healthy eating habits.

Methods

A probability sample of two ethnic minority groups in Yunnan Province, Southwest China were included (n = 1,033, mean age 47.5 ± 14.7 years). Bonding and bridging social capital (BOC and BRC) were assessed with the Personal Social Capital Scale (PSCS-16). Dietary data were evaluated with the Chinese Healthy Eating Index (CHEI), a measure of diet quality which reflects adherence to the Chinese Dietary Guidelines. NK and SS were measured with a validated questionnaire and scale, respectively. Structural Equation Modeling was used to calculate the direct, indirect and total effects of social capital on CHEI scores.

Results

The mean score of CHEI was 57.4 ± 9.8, which was significantly lower in men and older people. Low adherence to dietary guidelines were to observed in the consumption of dairy, beans, nuts, animal-source food vegetables and fruits. BOC and BRC were positively associated with CHEI score (β = 0.37 and 0.38, all p < 0.05). Social support and nutrition knowledge mediated 45.9 and 39.5% of the total effect of social capital on CHEI score, respectively.

Conclusion

Social capital appears to enhance adherence to dietary guidelines by improving nutrition knowledge and social support. Nutrition promotion programs therefore should consider incorporating strategies that foster social capital development, particularly in disadvantaged populations.

Does health literacy mediate the relationship between socioeconomic status and health related outcomes in the Belgian adult population?

BACKGROUND

Health literacy (HL) has been put forward as a potential mediator through which socioeconomic status (SES) affects health. This study explores whether HL mediates the relation between SES and a selection of health or health-related outcomes.

METHODS

Data from the participants of the Belgian health interview survey 2018 aged 18 years or older were individually linked with data from the Belgian compulsory health insurance (n = 8080). HL was assessed with the HLS-EU-Q6. Mediation analyses were performed with health behaviour (physical activity, diet, alcohol and tobacco consumption), health status (perceived health status, mental health status), use of medicine (purchase of antibiotics), and use of preventive care (preventive dental care, influenza vaccination, breast cancer screening) as dependent outcome variables, educational attainment and income as independent variables of interest, age and sex as potential confounders and HL as mediating variable.

RESULTS

The study showed that unhealthy behaviours (except alcohol consumption), poorer health status, higher use of medicine and lower use of preventive care (except flu vaccination) were associated with low SES (i.e., low education and low income) and with insufficient HL. HL partially mediated the relationship between education and health behaviour, perceived health status and mental health status, accounting for 3.8-16.0% of the total effect. HL also constituted a pathway by which income influences health behaviour, perceived health status, mental health status and preventive dental care, with the mediation effects accounting for 2.1-10.8% of the total effect.

CONCLUSIONS

Although the influence of HL in the pathway is limited, our findings suggest that strategies for improving various health-related outcomes among low SES groups should include initiatives to enhance HL in these population groups. Further research is needed to confirm our results and to better explore the mediating effects of HL.

Relationships among Sleep Time, Physical Activity Time, Screen Time, and Nutrition Literacy of Adolescents: A Cross-Sectional Study in Chongqing, China

Background: Unhealthy lifestyles among adolescents are reaching alarming levels and have become a major public health problem. This study aimed to assess the relationship between sleep time, physical activity (PA) time, screen time (ST), and nutritional literacy (NL). Methods: This cross-sectional online study involving adolescents aged 10-18 years was conducted in September 2020 in 239 schools in Chongqing, China. NL was measured using the "Nutrition Literacy Scale for middle school students in Chongqing (CM-NLS)". According to the recommended by the Chinese dietary guidelines (2022), we divided the sleep time of junior high school students into <9 h and ≥9 h, high school students into <8 h and ≥8 h, divided the workdays into weekend PA time < 1 h and ≥1 h, and divided the workdays into weekend ST < 2 h and ≥2 h. The multinomial logistic regression model was used to examine the association. Results: A total of 18,660 adolescents (50.2% males) were included. The proportion of participants that were junior high school students and attended boarding schools was 57.2% and 65.3%, respectively. Compared with senior high school students, junior high school students had a higher level of NL. Whether on workdays or weekends, participants with sleep time ≥ 8/9 h, PA time ≥ 1 h, and ST < 2 h per day had higher levels of NL. On weekdays, participants who met the sleep time ≥ 8 h/9 h (OR = 1.48, 95% CI: 1.36, 1.62) and PA time ≥ 1 h (OR = 1.69, 95% CI: 1.59, 1.81) had higher reporting of NL levels. Conclusions: Sleep time, PA time, and ST were positively correlated with NL among adolescents, especially junior high school students.

Association between social capital and quality of life in older adults with subjective cognitive decline: A cross-sectional study

BACKGROUND

Subjective cognitive decline (SCD) is increasingly recognized as a clinical and medical risk factor for mild cognitive impairment (MCI) and dementia. Currently, there is little evidence regarding the quality of life (QoL) in older adults with SCD and the impact of social capital on their QoL.

AIMS

To examine the perceptions of social capital and QoL among older adults with SCD.

METHODS

A total of 325 participants (92.9 % response rate) with a self-reported diagnosis of SCD completed the Chinese version of the 36-item Short-Form Health Survey, the Chinese Shortened Social Capital Scale and the Generalized Anxiety Disorder Scale. A t-test was used to compare the QoL score of our sample with the Chinese norm. Pearson correlation analysis and multivariate linear regression analysis were used to assess the association of social capital with QoL.

RESULTS

Social capital were strongly correlated with the total QoL, as well as its physical component summary and mental component summary. The QoL score of older adults with SCD was significantly lower than the Chinese norm (P < 0.001). Multivariate analysis showed that social capital, physical activity, nutrition and anxiety symptoms were factors associated with QoL among older SCD population (P < 0.05).

CONCLUSION

The findings of the current study suggest that older adults with SCD may experience lower QoL. Social capital is associated with the QoL in older adults with SCD. These findings have implications for clinicians who work with older adults with SCD.

Association between cultural capital and health literacy during the COVID-19 pandemic among community residents in China: the mediating effect of social capital

Background

Health literacy is crucial for managing pandemics such as COVID-19 and maintaining the health of the population; our goal was to investigate the impact of cultural capital on health literacy during the COVID-19 pandemic among community residents and to further examine the mediating role of social capital in the relationship between cultural capital and health literacy.

Methods

A cross-sectional study was conducted among 1,600 community residents selected in Chongqing, China using a stratified random sampling method. Data were gathered through a questionnaire survey, including sociodemographic characteristics, cultural capital, social capital, and health literacy. Chi-square analysis, one-way ANOVA, t-test, and hierarchical linear regression were used to analyze the level of health literacy among community residents and the related elements; the structural equation model (SEM) was used to explore the influential mechanisms of health literacy and explore whether social capital acted as a mediator in the relationship between cultural capital and health literacy.

Results

Cultural capital, community participation, community trust, reciprocity, and cognitive social capital had a significant positive effect on health literacy. In addition, the results of SEM indicated that cultural capital not only directly influences health literacy (β = 0.383, 95% CI = 0.265-0.648), but also indirectly influences health literacy through three types of social capital (β = 0.175, 95% CI = 0.117-0.465; β = 0.191, 95% CI = 0.111-0.406; β = 0.028, 95% CI = 0.031-0.174); its mediating effect accounting for 50.7% of the overall effect.

Conclusions

Our results highlight the empirical link between cultural capital and health literacy, and suggest that social capital mediates this connection. These findings suggest that governments and communities should focus on the construction of community cultural capital and provide residents with better social capital to improve their health literacy to prepare for future pandemics.

Health and quality of life among women after participation in a CBPR-informed physical activity intervention: with a pandemic perspective

The lack of culturally and contextually oriented interventions promoting physical activity (PA) has led to increased physical inactivity among women living in disadvantaged neighbourhoods in Sweden. In this study one such intervention informed by community-based participatory research (CBPR) has been evaluated among 34 women from a disadvantaged neighbourhood before and during COVID-19. Health-related quality of life (HRQOL), behavioural and biomedical outcomes were assessed directly prior and post-intervention, followed by evaluations at 6-months and 18-months follow-up during COVID-19. The results revealed that HRQOL, particularly psychological, social, and environmental health significantly increased post-intervention compared to prior to intervention but reversed back at 6-months follow-up. Perceived health satisfaction and environmental health increased at 18-months follow-up during COVID-19. Participation in PA improved post-intervention and at 6-months follow-up. Everyday activities and fruit and vegetable intake continued to increase through all timepoints. Systolic blood pressure significantly decreased post-intervention and 6-months follow-up; blood flow rate increased significantly at all timepoints. Overall, the findings underscores the potential effectiveness of CBPR approaches in promoting and sustaining healthy lifestyles, even during acute situations such as the COVID-19. It may even serve as a future model for promoting health and addressing health disparities in similar groups.

The effect of anxiety, depression, and structural social capital on life satisfaction among people with hearing disabilities: a cross-sectional study in Shanghai, China

Background

Life satisfaction (LS) serves as a crucial indicator of social wellbeing and plays a significant role in formulating strategies aimed at enhancing health outcomes among the hearing-disabled population. This study aimed to examine the effect of anxiety, depression, and structural social capital on life satisfaction among people with hearing disabilities in Shanghai, China.

Methods

A cross-sectional study was conducted in Shanghai, China. As of March 2022, 337 people with hearing disabilities were recruited from the Shanghai Disabled Persons' Federation. An online survey was conducted using a four-part questionnaire to collect data including demographic characteristics, the Hospital Anxiety and Depression Scale (HADS), the Social Capital Scale (SCS), and a single-item question to measure life satisfaction. One-sample t-tests, Pearson's correlation analysis, and hierarchical multiple regression analysis were performed.

Results

Anxiety (β = - 0.153) and depression (β = - 0.242) were significant factors influencing life satisfaction among people with hearing disabilities. Structural social capital also played an influential role in life satisfaction, and people with hearing disabilities who lack social networks (β = 0.125) and social support (β = 0.121) reported significantly lower levels of life satisfaction. However, no significant relationship was found in this study between LS and other components of structural social capital, such as social participation.

Conclusion

This study shows that paying attention to mental health is critical for people with hearing disabilities to achieve social wellbeing and promote LS improvement. At the same time, the government and society also need to focus on the structural social capital, provide various social service programs, enhance social support, and expand social networks, improving LS for people with hearing disabilities.

Association between neighbourhood cohesion and physical activity trajectories during the COVID-19 pandemic using data from Understanding Society: The UK Household Longitudinal Study & COVID-19 sub-study

Neighbourhood cohesion is increasingly recognised as a key determinant of health and health-related behaviours. Positive association between social support and physical activity have been demonstrated on an interpersonal level, there is less evidence at group-level. This study aimed to examine the association between neighbourhood cohesion and physical activity trajectories during the COVID-19 pandemic. Hypothesizing that higher neighbourhood cohesion was a protective factor against reduced physical activity during the pandemic. Data from Understand Society (wave 9, Jan 2017-Dec 2019), and the COVID-19 sub-study (waves 1, 5, 7) was used. Participants (N = 14,475) had baseline data and at least one Covid physical activity measure. We used linear mixed models with a random intercept and slope at the individual level and an unstructured correlation matrix to examine the association between neighbourhood cohesion and physical activity during the follow-up period. We found a significant reduction in physical activity (-441 MET-min/wk, (CI 374.51 - 507.65, p < 0.001) through the COVID-19 pandemic, and that higher neighbourhood cohesion was related to higher physical activity after control for covariates. There was a significant difference between neighbourhood cohesion categories and change seen in PA during the 39-month follow-up period (difference in change between lowest and highest neighbourhood cohesion categories = 373 MET-min/wk, p = 0.036), higher neighbourhood cohesion had a protective effect. Strong relationships between public health and urban planning sectors are needed to build communities with structures in place to support a sense of community, social interaction and attraction to the neighbourhood. This will help long-term neighbourhood cohesion and support increased physical activity.

The mediating effect of family health on the relationship between health literacy and mental health: A national cross-sectional survey in China

BACKGROUND

Mental health problems significantly affect people's well-being and result in a huge health burden. Health literacy and family health are critical to reducing people's mental health problems. However, limited studies have addressed their complex interaction. Thus, this study aims to elucidate the mediating effect of family health on the relationship between health literacy and mental health.

METHODS

A national cross-sectional study based on multistage random sampling was conducted from July 10 to Sep 15, 2021, in China. Information about the public's health literacy, family health, and the level of three common mental health problems (depression, anxiety, and stress) was collected. A structural equation model (SEM) was applied to explore the mediating effect of family health on the relationship between health literacy and mental health.

RESULTS

A total of 11,031 participants were investigated. Approximately 19.93 and 13.57% of participants experienced moderate or severe depressive and anxiety symptoms, respectively. The SEM showed that health literacy was directly associated with mental health, with higher health literacy resulting in lower levels of depression (coefficient: -0.018, p = .049), anxiety (coefficient: -0.040, p < .001), and stress (coefficient: -0.105, p < .001). In addition, family health played a significant mediating effect (p < .001) between health literacy and mental health, contributing to 47.5, 70.9, and 85.1% of the total effect of health literacy on personal stress, anxiety, and depression, respectively.

CONCLUSIONS

This study revealed that the improvement of health literacy is directly and indirectly associated with less likelihood of people's mental health problems via family health. Thus, future mental health interventions should be integrated and targeted both at individual level and the family level.

The Relationships between Social Capital, Metabolic, and Behavioral Risk Factors of Non-Communicable Diseases: A Systematic Review

Background

Contextual risk factors such as social capital have a vital role in affecting behavioral and biological risk factors of NCDs. We aimed to systematically identify the relationship between different aspects of social capital (SC) with metabolic, and behavioral risk factors of non-communicable diseases (NCDs).

Methods

This is a systematic review. The period of study was 2000-2021. We searched the English international databases, i.e. PubMed/Medline, Scopus, and Web of Science. Studies that reported NCDs' metabolic and behavioral risk factors as independent variables, were excluded. We also included studies if they analyzed the association between SC and metabolic and behavioral risk factors of NCDs.

Results

After the primary and quality appraisal process, 97 studies were entered in the final phase of the analysis. Five out of 18 studies reported an inverse association between SC and the level of alcohol drinking. Twenty-seven out of 32 studies reported a significant inverse association between SC and smoking and tobacco use, while only one study reported a significant positive association. Nine studies reported a significant inverse association between SC and high blood pressure. Three studies showed a significant inverse association between SC and diabetes. Seventeen studies indicated a significant positive association between SC and physical activity. Thirteen out of 17 studies reported a significant inverse association between SC, body mass index (BMI) and overweight.

Conclusion

High SC, people's participation and interaction are vital in tackling NCDs. Evidence shows positive effects of SC on prevention, control and improvement of NCDs' metabolic and behavioral risk factors.

The nutritional literacy of breast cancer patients receiving chemotherapy and its association with treatment self-regulation and perceived social support

PURPOSE

Chemotherapy can lead to malnutrition and post-menopausal recurrence among breast cancer (BC) patients, who need to achieve nutritional literacy (NL) to cope. The objective of this study was to explore the NL level in Chinese BC patients receiving chemotherapy and its predictors including both internal motivation and the external environment.

METHODS

A total of 326 BC female patients from three hospitals were enrolled. Participants completed the Nutrition Literacy Measurement Scale for Chinese Adult (NLMS-CA), Chinese version from the Treatment Self-Regulation Questionnaire (TSRQ-C), and the Perceived Social Support Scale (PSSS) to assess NL, treatment self-regulation, and social support. Stepwise multivariate linear regression was used to identify the main factors of NL.

RESULTS

The total NL score was 151.31 ± 16.85, the "knowledge understanding" dimension had the lowest score. In the final regression model, patients with higher scores for "autonomous motivation" and "introjected regulation" on the TSRQ-C and "family support" and "other support" on the PSSS, higher educational levels and average monthly household incomes and endocrine therapy had higher NL levels (adjusted R2 = 66.7%, p < 0.05).

CONCLUSIONS

The overall NL score among Chinese BC patients receiving chemotherapy was satisfactory, but the knowledge understanding score was low. Higher autonomous motivation, introjected regulation, family support and other support scores, higher educational and household income levels, and endocrine therapy were predictors of NL in female patients. Interventions should be designed according to the specific performances and predictors of NL in female patients.

Exploring dimensions of social capital in relation to healthy eating behaviours in the US rural south

OBJECTIVE

This study examined relationships between dimensions of social capital (SC) (social trust, network diversity, social reciprocity and civic engagement) and fruit, vegetable, and sugar-sweetened beverage (SSB) consumption among rural adults. Potential moderators (neighbourhood rurality, food security, gender and race/ethnicity) were explored to develop a more nuanced understanding of the SC-healthy eating relationship.

DESIGN

Data were from a 2019 mailed population-based survey evaluating an eleven-county initiative to address health equity. Participants self-reported health behaviours, access to health-promoting resources and demographics. Logistic regression models were used to analyse relationships between predictors, outcomes and moderators.

SETTING

Five rural counties, Georgia, USA.

PARTICIPANTS

1120 participants.

RESULTS

Among participants who lived in the country (as opposed to in town), greater network diversity was associated with consuming ≥ 3 servings of fruit (OR = 1·08; 95 % CI 1·01, 1·17, P = 0·029), yet among participants who lived in town, greater civic engagement was associated with consuming ≥ three servings of fruit (OR = 1·36; 95 % CI 1·11, 1·65, P = 0·003). Both food-secure and food-insecure participants with greater social reciprocity had lower odds of consuming 0 SSB (OR = 0·92; 95 % CI 0·86, 0·98, P = 0·014, OR = 0·92; 95 % CI 0·86, 0·99, P = 0·037, respectively). Men with greater social trust were more likely to consume 0 SSB (OR = 1·09; 95 % CI 1·01, 1·18, P = 0·038), and Whites with greater network diversity were more likely to meet daily vegetable recommendations (OR = 1·10; 95 % CI 1·01, 1·19, P = 0·028).

CONCLUSIONS

Findings provide a basis for future qualitative research on potential mechanisms through which SC and related social factors influence healthy eating in rural communities.

Physical Inactivity and Food Insecurity Are Associated with Social Capital: A Large-Scale Population-Based Study in Tehran

Background. There are limited studies on food security, physical activity, and social capital in the Iranian population. This study aimed to evaluate the social capital’s associations with physical inactivity and food insecurity in a large-scale study in Iran, Urban HEART-2. Methods. This cross-sectional study was conducted in 22 districts of Tehran, the capital of Iran. Residents of Tehran who were 15 years or older were selected by a multi-stage, stratified, and random sampling method. Food insecurity and physical activity were evaluated using Household Food Security Scale and Global Physical Activity Questionnaire, respectively, and their associations with social capital were evaluated. Results. A total of 5030 individuals were included in this study, with 3139 (62.4%) males. The mean age of participants was 44.08 years (SD = 16.33, range = 15–90). Participation in social events (OR = 0.893, 95% CI = 0.819–0.974, $P$  = 0.011), social network (OR = 0.849, 95% CI = 0.786, $P$  < 0.001), and voluntary activities (OR = 0.865, 95% CI = 0.812–0.921, $P$  < 0.001) were all negatively associated with food insecurity. Also, voluntary activities (OR = 0.823, 95% CI = 0.776–0.872, $P$  < 0.001) and participation in the associations activities (OR = 0.665, 95% CI = 0.582–0.759, $P$  < 0.001) were negatively associated with physical inactivity. Conclusion. The prevalence of food insecurity and physical inactivity is relatively high among Tehran residents. As a factor affecting the physical activity and food security, social capital can be targeted in interventions to improve physical activity and food security among Iranians.

Social capital and health information seeking in China

Background

People’s potentials to seek health information can be affected by their social context, such as their social networks and the resources provided through those social networks. In the past decades, the concept of social capital has been widely used in the health realm to indicate people’s social context. However, not many such studies were conducted in China. Chinese society has its special quality that many Western societies lack: people traditionally render strong value to family relations and rely heavily on strong social ties in their social life. Therefore, the purpose of this study was to examine the association between different types of social capital and health information-seeking behavior (HISB) in the Chinese context. The different types of social capital were primarily bonding and bridging, as well as cognitive and structural ones.

Methods

Our analysis is based on a total of 3090 cases taken from the Health Information National Trends Survey (HINTS) – China, 2017. Dataset was weighted due to the overrepresentation of female respondents and hierarchical multiple regression analyses as well as binary logistic regression tests were operated to examine the associations between people’s social capital and their HISB.

Results

Some aspects of social capital emerged as positive predictors of HISB: information support (standing in for the cognitive component of social capital) promoted health information seeking, organization memberships (standing in for the structural component) encouraged cancer information seeking, and both the use of the internet and of traditional media for gaining health information were positively linked with bridging networks and organization memberships. Bonding networks (structural component) were not correlated with any other of the key variables and emotional support (cognitive social capital) was consistently associated with all health information-seeking indicators negatively.

Conclusions

Social capital demonstrated significant and complex relationships with HISB in China. Structural social capital generally encouraged HISB in China, especially the bridging aspects including bridging networks and organization memberships. On the other hand, emotional support as cognitive social capital damaged people’s initiatives in seeking health-related information.

Light, moderate and vigorous physical activities: New insights into a virtuous circle with happiness

The study of the physical activity engagement (PA) has given rise to a relevant research agenda in a wide range of fields, such as its close relationship with subjective well-being, self-perceived health and social capital. Previous evidence has identified interrelationships among these variables, but without considering different levels of physical activity. We have thus considered three levels of activity: light (walking), moderate and vigorous. Structural Equation Modelling (SEM) is undertaken on data from Spain's National Health Survey in 2011-2012 to analyse these interrelationships. The SEM shows a simultaneous and bidirectional relationship between different levels of PA (moderate and vigorous activities) and happiness, with a more robust association stemming from happiness to PA than vice versa. This relationship is mediated through health. From a policy perspective, this implies a virtuous circle: involvement in different levels of PA increases happiness and self-perceived health, while happiness involves higher PA and subsequent positive increases in health and happiness. Nevertheless, this virtuous circle does not always run successfully when social capital is considered to mediate the relationship between PA and happiness, which might explain why it has proven to be very difficult for health policymakers to fight against inactivity and a sedentary lifestyle within a great part of the population.Highlights We investigate bidirectional interrelationships between different levels of physical activity (PA) and happiness.We consider the mediation role played by self-perceived health (SPH) and social capital.Our results highlight a network of association between different levels of PA, SPH, social capital and happiness.SPH positively mediates this relationship for any type of PA level, whereas social capital only mediates positively when vigorous PA is developed.From a health policy perspective, the simultaneity between PA levels and happiness implies a virtuous circle.

Identifying the specific associations between participation in social activities and healthy lifestyle behaviours in older adults

OBJECTIVES

To examine the longitudinal association between participation in social activities and healthy lifestyle behaviours.

STUDY DESIGN

This 2-year follow-up study used data from 6168 older adults (73.5 ± 5.3 years; 49% men). We studied participation in five types of social activities at baseline: participation in volunteer, sports, hobbies, senior clubs, and neighbourhood-association groups.

MAIN OUTCOME MEASURES

The healthy lifestyle behaviours were physical activity (time spent walking: ≥150 min/week; or less), eating habits (dietary variety score: ≥4 points; or less), and intellectual activity (subcomponents of the Tokyo Metropolitan Institute of Gerontology Index of Competence: 4 points; or less).

RESULTS

In the follow-up survey, 19% of participants were physically inactive, 53% had unfavourable eating habits, and 34% had diminished intellectual activity. Multilevel modified Poisson regression analysis showed that participation in sports groups was associated with a lower relative risk (RR) of physical inactivity (RR=0.82 [0.72, 0.93]) and unfavourable eating habits (RR=0.95 [0.90, 1.00]). Participation in hobby groups reduced the RR of unfavourable eating habits (RR=0.93 [0.90, 0.97]) and diminished intellectual activity (RR=0.90 [0.85, 0.96]). Participation in volunteering was associated with a lower RR of diminished intellectual activity (RR=0.84 [0.75, 0.95]). Relative to non-participation, participating in two or more social activities was associated with a 9% (95% CI: 0.83, 1.00) lower RR for physical inactivity, a 12% (95% CI: 0.82, 0.95) lower RR for unfavourable eating habits, and a 17% (95% CI: 0.77, 0.89) lower RR for diminished intellectual activity.

CONCLUSIONS

Both the nature and the number of social activities determine the longitudinal effects of social participation on healthy lifestyle behaviours.

Effects of social participation and physical activity on all-cause mortality among older adults in Norfolk, England: an investigation of the EPIC-Norfolk study

OBJECTIVES

There is growing evidence of an association between social participation and improved physical and mental health among older individuals. The aims of this study were to explore the relationship between self-reported participation in groups, clubs, or organizations and all-cause mortality among older adults and examine the role of physical activity as a potential modifier of the health effects of social participation.

STUDY DESIGN

EPIC-Norfolk is a prospective cohort study that recruited 25,639 individuals between the ages of 40 and 79 in Norfolk County, England. This study involved a retrospective analysis of 8623 participants who had returned for the third health check between 2004 and 2011.

METHODS

Participants were categorized into those who reported participating socially and those who did not and were stratified by involvement in 0, 1, or 2 or more groups. Cox Proportional Hazards models were constructed to compare all-cause mortality between the groups. Stratum-specific hazard ratios were calculated by physical activity level to assess for effect modification.

RESULTS

Of the participants, 861 (9.98%) died during the follow-up period. After adjustment for confounding, social participation was associated with lower all-cause mortality (HR 0.84, 95% CI 0.73-0.97). Involvement in 2 or more groups was associated with lower all-cause mortality (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.70-0.97), but the association was not statistically significant for people involved in only 1 group (HR 0.86, 95% CI 0.73-1.03). Physical activity appeared to modify the effect of social participation on mortality.

CONCLUSIONS

This study's findings provide evidence of an association between social participation and lower all-cause mortality for older adults. They also suggest that the effect of social participation on health is greater for people who are more physically active. Population-level interventions to facilitate social participation may contribute to improving health and wellbeing among older individuals.

Social networks moderate the association between physical fitness and cognitive function among community-dwelling older adults: a population-based study

BACKGROUND

Physical fitness declines with age. Low levels of physical fitness appear to be a risk factor of cognitive impairment. Literature elucidates social networking as a potential moderator for the relationship between physical fitness and cognitive impairment. Present study aimed to examine the relationship between physical fitness and cognitive function among community-dwelling older Malaysians, and if social network moderates said relationship.

METHODS

Data of 2322 representative community-dwelling older adults were obtained from the first wave of the "Longitudinal Study on Neuroprotective Model for Healthy Longevity" national survey. Cognitive function, physical fitness and social network was assessed through Malay-version of Mini-Mental State Examination, 2-min step test and Lubben Social Network Scale-6 respectively. Moderated hierarchical multiple regression was employed to investigate if social networks moderate the relationship between physical fitness and cognitive function.

RESULTS

A positive association between physical fitness and cognitive function were found upon controlling for covariates. Moderated hierarchical multiple regression revealed social networks to be a moderator of the association between physical fitness and cognitive function. When physical fitness was low, those with small social network revealed lowest cognitive function.

CONCLUSIONS

Social networks moderated the relationship between physical fitness and cognitive function as older adults with low levels of physical fitness and small social networks revealed lowest cognitive function. Therefore, community support or peer-based interventions among physically unfit older adults should be implemented to promote cognitive function.

Identifying drivers and factors affecting behavioral risk factors of noncommunicable diseases: A scoping review

BACKGROUND

A large proportion of noncommunicable diseases (NCDs) can be prevented by reducing unhealthy nutrition, inadequate physical activity, smoking, and alcohol consumption. The high burden of NCDs underlines the need for a greater understanding of the causes of these risk factors. This paper aims to identify factors affecting smoking, alcohol consumption, unhealthy nutrition, and inadequate physical activity in current and future times.

MATERIALS AND METHODS

A scoping review was conducted in Iran University of Medical Sciences, Tehran, Iran, in 2020 to identify factors affecting smoking, alcohol consumption, unhealthy nutrition, and inadequate physical activity. The review was guided by the five-step Arksey and O'Malley model. A deductive qualitative content analysis was employed to identify the factors synthesized through descriptive and narrative synthesis. The search was conducted in English without date restrictions up to January 2020.

RESULTS

We identified 1437 studies through database search and other sources and finally included 72 studies in the review. The content analysis of the data led to the identification of 27 factors affecting smoking, alcohol consumption, nutrition, and physical activity. The factors categorized into social, technological, environmental, economic, political, and values factors.

CONCLUSION

Political and economic factors have a significant effect on all risk factors, and it is necessary to take comprehensive measures to improve these factors. Technological factors have a greater impact on healthy nutrition. Physical activity is more affected by environmental factors than other risk factors. However, smoking and alcohol consumption are more influenced by social factors and individual attitudes.

Recursive Path Model for Health Literacy: The Effect of Social Support and Geographical Residence

Background: The public health relevance of health literacy is highlighted by the fact that its higher levels can improve health outcomes and reduce health inequities. In order to design effective interventions for improving health literacy, the relationship between health literacy and other factors such as sociodemographic variables, subjective health and social support must be understood. Objective: Our aim was to test a socioecological model of the determinants of health literacy with a special focus on the effect of residence. Our study investigated geographical differences regarding the levels of health literacy and its determinants as this was not investigated before in European nationwide surveys. Methods: Data was collected by a polling company in a sample (n = 1,200) of the Hungarian adult population nationally representative by age, gender, and permanent residence in 2019 January. The questionnaire included items on sociodemographic data, subjective well-being, social support, and two health literacy scales. A recursive path model was used to outline the mediating effect of social support between sociodemographic variables and health literacy where both direct and indirect effects of the explanatory variables and multiple relationships among the variables were analyzed simultaneously. Multiple-group analysis was applied to the three pre-set categories of permanent residence (capital city, urban and rural). Results: There was no statistically significant difference by residence regarding levels of health literacy. Social support and educational attainment were the most important determinants of health literacy after adjusting for the effect of other sociodemographic variables. However, the magnitude of effect of social support and educational attainment is different between types of settlements, the strongest being in rural areas. Conclusion: Social support seems to mediate the effect of socioeconomic position on health literacy which could be taken into account when designing interventions to improve health literacy, especially in rural areas. Further studies would be needed especially in rural communities to see whether improvement of social support could be utilized in projects to increase the level of health literacy.

The Impacts of Regional Regulatory Policies on the Prevention and Control of Chronic Diseases in China: A Mediation Analysis

Regional regulatory policies (RPs) are a major factor in the prevention and control of chronic diseases (PCCDs) through the implementation of various measures. This study aimed to explore the impacts of RPs on PCCDs, with a focus on the mediating roles of community service. The soundness of the regulatory mechanism (SORM) was used to measure the soundness of RPs based on 1095 policy documents (updated as of 2015). Coverage provided by community service institutions (CSIs) and community health centres (CHCs) was used to represent community service coverage derived from the China Statistical Yearbook (2015), while the number of chronic diseases (NCDs) was used to measure the effects of PCCDs based on data taken from the 2015 China Health and Retirement Longitudinal Study survey. To assess the relationship between SORM, NCDs and community service, a negative binomial regression model and mediation analysis with bootstrapping were conducted. Results revealed that there was a negative correlation between SORM and NCDs. CSIs had a major effect on the relationship between RPs and PCCDs, while CHCs had a partial mediating effect. RPs can effectively prevent and control chronic diseases. Increased effort should also be aimed at strengthening the roles of CSIs and CHCs.

Relationship Between Mental Health, Resilience, and Physical Activity in Older Adults: A 2-Year Longitudinal Study

The aim of this study was to longitudinally investigate the association between resilience and mental health in older adults and to determine the influence of physical activity on this relationship. A total of 291 older adults were included in a 2-year follow-up study. Adjusted linear regression models evaluated the association between resilience at baseline and mental health after 2 years in sufficiently and insufficiently physically active older adults. A negative correlation was found between resilience at baseline and depression, anxiety, and stress after 2 years for the overall sample. This association changed after stratifying the group. Sufficiently physically active individuals made greater use of the resilience components "Self-Sufficiency" and "Perseverance," whereas insufficiently physically active individuals made greater use of "Meaning of Life" and "Existential Singularity." Physical activity can influence the relationship between resilience and mental health. These results can help guide the devising of more effective interventions for this age group.

Social capital and dietary patterns in three ethnic minority groups native to Yunnan Province, Southwest China

BACKGROUND

Few studies have focused on the influencing factors of dietary practices among ethnic minority groups in China, particularly from a social capital perspective.

METHODS

Between May and September 2019, we conducted a cross-sectional survey among adults (n = 1,813) from three ethnic minority communities (A Chang, De Ang and Jing Po) in Yunnan Province, Southwest China. Dietary intakes during the past 12 months were measured with a 100-item Food Frequency Questionnaire (FFQ), and two forms of social capital (bonding and bridging) were measured using the validated Personal Social Capital Scale 16 (PSCS-16). Principal component factor analysis was used to derive dietary patterns from 20 food groups. Multivariate linear regressions were used to examine the associations between social capital and dietary patterns.

RESULTS

Two distinct dietary patterns were identified: the traditional and the modern. The traditional pattern was characterized by high consumptions of tubers, poultry, rice, fruits, vegetables and low consumptions of oil and salt, whereas the modern pattern was highly correlated with egg, nut, beverage, snack and oil consumptions. After adjusted for potential confounders, the modern pattern was positively associated with bonding capital (β = 0.066; 95%CI: 0.058, 0.075) and negatively associated with bridging capital (β = -0.017; 95%CI: -0.024, -0.010).

CONCLUSION

In conclusion, an unhealthy dietary pattern was identified among the ethnic minority groups in Southwest China. The influences of people's social connections on dietary behaviors should be considered in designing and implementing nutrition intervention programs for the population.

The Pathways Linking to Sleep Habits among Children and Adolescents: A Complete Survey at Setagaya-ku, Tokyo

It has been noted that Japanese children sleep the least in the world, and this has become a major social issue. This study examined the pathways linked to sleep habits (SH) among children and adolescents. A questionnaire-based survey was conducted in March 2019 on children and their parents at all 63 public elementary and 29 public junior high schools in Setagaya-ku, Tokyo. For the analysis, 22,385 pairs of children-parent responses (valid response rate: 68.8%) with no missing data were used. This survey collected data on SH, physical activity (PA), screen time (ST) for the child, and lifestyle and neighborhood social capital (NSC) for the parents. Moreover, the pathways linking 'NSC' → 'parental lifestyle' → 'child's PA/ST' →'child's SH' were examined through structural equation modeling. The results indicated that children's SH were affected by their PA and ST and influenced by the lifestyle of their parents and the NSC that surrounds them. Thus, we concluded that it is necessary to provide direct interventions and take additional measures with regard to parent lifestyle and their NSC to solve persistent sleep problems in children.

Health literacy and health outcomes in China's floating population: mediating effects of health service

Background

The floating population in China consists primarily of internal immigrants and represents a typical health vulnerable group. Poor health literacy has recently become an obstacle in the accessibility and utilization of health services for the vulnerable population, leading to adverse health outcomes. This study aimed to examine whether health literacy affected health outcomes in China’s floating population and whether health service utilization had a mediating effect between health literacy and health outcomes.

Method

The current study utilized a cross-sectional stratified, multistage, proportional to scale (PPS) study in Zhejiang Province, China, in November and December 2019. In total, 657 valid self-reported questionnaires were recovered and used for data collection. Questionnaires included questions regarding sociodemographic characteristics, health literacy, health outcomes, and health service utilization. Confirmatory factor analysis was used to test questionnaire validity; descriptive statistics were used to understand the demographic characteristics of the floating population; and structural equation modeling was used to determine whether health service utilization mediated health literacy and health outcomes.

Results

We report positive correlations between health literacy, health service utilization, and health outcomes. Mediation analysis demonstrated that health service utilization had partial mediating effects between health literacy and health outcomes. In the relationship between health literacy and health outcomes, the indirect effects of health service utilization accounted for 6.6–8.7% of the total effects.

Conclusion

Complete health literacy, through health care literacy and health promotion literacy, affects the mobile population’s initiative to use health services, which, in turn, affects health outcomes. Thus, improving the health literacy of the floating population will help to improve health outcomes. Furthermore, health service providers should enhance the diversity of health service supply to ensure that the floating population has the external resources to improve personal health literacy.

The Association Between Health Literacy and Self-rated Health Among Residents of China Aged 15-69 Years

INTRODUCTION

Health literacy is a critical determinant of health. However, the association between health literacy and outcomes among Chinese residents has not been studied using nationally representative data. This study examines the association between health literacy and self-rated health among Chinese residents based on the 2017 China Health Literacy Survey.

METHODS

The 2017 China Health Literacy Survey was conducted among non-institutionalized residents aged 15-69 years from 31 provinces in China. Self-rated health was measured using a single question with a 1-5 scale. Health literacy was assessed using the Chinese Health Literacy Scale. Multilevel linear regression models examined the association between health literacy and self-rated health. Data were collected in 2017 and analyzed between 2018 and 2019.

RESULTS

The final sample size was 85,384. The overall weighted mean of the self-rated health score was 4.02 (95% CI=4.00, 4.03). After adjusting for individual-, county-, and province-level covariates, Chinese residents with higher levels of health literacy were more likely to have better self-rated health (β=0.0007, SE=0.0002, p<0.001). Of 6 dimensions of health literacy, 4 (i.e., infectious diseases literacy, chronic diseases literacy, medical care literacy, and health information literacy) were associated with self-rated health. Additionally, self-rated health was associated with gender, age, education, occupation, annual household income, and chronic conditions.

CONCLUSIONS

Using nationally representative data collected in 2017, this study found that self-rated health is associated with health literacy among Chinese residents aged 15-69 years. The promotion of health literacy should be an important component of health education, patient management, and health promotion.

The Direct and Indirect Relationships of Environmental, Interpersonal and Personal Factors with High School Students Physical Activity: An Ecological Approach

BACKGROUND

Across countries, young people are not sufficiently physically active. The evidence confirms that beyond demographic and individual agents, individuals participate within their social and physical environment. The ecological model enables a search for the modifiable factors in specific populations, as it allows consideration of factors affecting individuals' lives on different levels, as well as considering the interplay of those factors. The aim of this study was to examine the complex interconnections among environmental, social capital and motivational factors at different levels, within an ecological model for high school students' moderate-to-vigorous physical activity during their leisure time.

METHODS

This cross-sectional population-based study included 1285 students from 14 to 18 years old, with a mean age of 16.14 ± 1.22. Physical activity, neighborhood physical activity recourses, neighborhood safety, social capital, physical activity motivation and sociodemographic factors were evaluated. Logistic regression, mediation and moderation analyses were performed predicting moderate-to-vigorous physical activity during leisure time.

RESULTS

In the final multivariate logistic regression model, greater social participation (OR 1.03 [1.01-1.05]), higher relative autonomy index (OR 1.11 [1.06-1.15]) and male gender (OR 1.71 [1.13-2.57]) directly predicted meeting MVPA recommendations. Any significant moderation effects (p > 0.05) of environmental characteristics were not found for the relationship between social capital, motivational factors and moderate-to-vigorous physical activity. The evidence of positive indirect mediation effects was found in all five models for social capital components as all CIs for its βs do not contain 0, though standardized effect sizes were between 0.02 and 0.07, indicating small effect sizes.

CONCLUSION

These findings provide support for the presence of some direct and indirect pathways from social capital to moderate-to-vigorous physical activity. Future intervention strategies should focus on strengthening physical activity motivation by encouraging the development of social network and social participation as well as family, neighborhood and school social capital within the framework of the ecological model.

The relationship among social capital, eHealth literacy and health behaviours in Chinese elderly people: a cross-sectional study

Background

Social capital has been linked to health behaviours, but the underlying mechanism is unclear. Previous studies have found that health literacy played the role of a mediator in the relationships among social capital, individual physical activity and nutrition. But it is not clear whether eHealth literacy mediates the impact of social capital on health behaviours. Therefore, our research aimed to explore the relationships among social capital (structural and cognitive social capital), eHealth literacy, and the health behaviours of elderly people, and to analyse the mediating effect of eHealth literacy, while providing a theoretical basis for a health behaviour intervention for elderly people.

Methods

From January to February 2019, we conducted a cross-sectional survey of 1201 Chinese people aged over 60 years using the Chinese Shortened Social Capital Scale (contains two subscales of structural social capital and cognitive social capital), eHealth Literacy Scale, and Health-Promoting Lifestyle Profile. We used structural equation modelling to test a hypothetical mediation model.

Results

The mean scores of social capital was 72.07 (SD = 13.03), 17.24 (SD = 9.34) for eHealth literacy, and 112.23 (SD = 23.25) for health behaviours. Social capital and eHealth literacy were significantly correlated with health behaviours, and social capital and structural social capital were significantly correlated with eHealth literacy. Lastly, eHealth literacy mediated the relationship between structural social capital and health behaviours.

Conclusions

eHealth literacy was an important mediating factor for elderly people’s structural social capital and health behaviours. Therefore, social capital and eHealth literacy must be considered when designing and implementing health behaviour intervention programmes for elderly people.

Effects of physical activity and stress on the relationship between social capital and quality of life among breast cancer survivors

This study aims to investigate the serial multiple mediation of physical activity and perceived stress in the relationship between individual social capital and quality of life (QOL) in breast cancer survivors (BCSs). This study was conducted among 520 BCSs between March and April 2017 in Shanghai, China. Data were collected using the Individual Social Capital Scale, the Health-Promoting Lifestyle Profile-II, the Perceived Stress Scale-14 and the EORTC QLQ-C30. Ordinary least-squares regression and the bootstrap method was used to test the significance of the serial multiple mediation model. The serial-multiple mediations of physical activity and perceived stress were found significant in the relationship of QOL with all five dimensions of individual social capital. The separate mediations of two single mediating variables were found significant in the relationship of QOL with control over life and feeling about the community. In the relationship of QOL with social participation, social network and social support, the separate mediation of physical activity was significant, while the separate mediation of perceived stress was not significant. A multidisciplinary team approach and a variety of delivery systems are needed to address the social, physical and psychological issues for improving QOL among BCSs.
