Self-efficacy, beliefs, and goals: Moderation of declining physical activity during adolescence

Determinants of moderate-to-high physical activity levels in hemodialysis patients: A multicenter cross-sectional study

Moderate physical activity is related to reduced mortality in hemodialysis patients. However, most hemodialysis patients have low physical activity levels for complex reasons. This study investigated the determinants of moderate-to-high physical activity levels and whether psychosocial correlates are associated with engagement in moderate-to-high physical activity among hemodialysis patients. A cross-sectional survey was conducted with 134 hemodialysis outpatients, aged 64.7 years, in three hemodialysis centers in Taiwan. Data on sociodemographics, comorbidities, lifestyles, and psychosocial correlates, including perceived benefits, barriers, and self-efficacy of physical activity, were collected. Multiple logistic regression analyses were performed. Results showed that patients with moderate-to-high physical activity levels constituted a significantly lower proportion of current smokers and had fewer perceived physical activity barriers and higher self-efficacy of physical activity compared with those with low levels. After adjusting for potential sociodemographic covariates, current employment, nonsmoking status, and high self-efficacy of physical activity were significantly associated with moderate-to-high physical activity levels. Developing strategies to improve the self-efficacy of physical activity, support employment, and enhance anti-smoking campaigns in hemodialysis patients can help them engage in moderate-to-high levels of physical activity.

A Comprehensive Planning Framework for Designing Effective Physical Activity Interventions in Youth

BACKGROUND

Effective physical activity (PA) interventions are needed to counter the insufficient and declining levels of PA in youth. These require an updated, comprehensive planning framework that consolidates recent decades of progress in promoting PA in young children, children, and adolescents. Effective PA interventions require program planning and conceptual model development that target a coordinated and multilevel set of age-specific PA determinants. Accordingly, this paper presents a comprehensive planning framework that researchers can use to design intervention research to promote PA in youth.

METHODS

The first author conducted targeted searches through Google Scholar to compile PA models/frameworks/guides applicable to youth, a comprehensive set of PA determinants, and determinant-linked strategies to promote PA focusing on review articles. The information was summarized in tables, synthesized, and used to create a planning framework, all of which were reviewed by coauthors.

RESULTS

The APPLE Framework for Planning PA Opportunities for Youth (APPLE = Age, PA focus, Place and time, Leverage relevant influences and strategies, and ensure Enjoyable PA opportunities) incorporated all core elements from targeted reviews to create a comprehensive planning framework. The APPLE Planning Framework has a set of questions/prompts that guide the intervention planning process and conceptual model templates to organize planning efforts for designing intervention research.

CONCLUSIONS

The APPLE Framework for Planning PA Opportunities for Youth will enable researchers to develop comprehensive conceptual models to guide the design of PA interventions for youth. Future research should refine the model and its components to enable PA intervention research in youth to move forward.

Fatigue and physical activity in post-CABG patients: the parallel mediation model of kinesiophobia and self-efficacy : a prospective multicentre and cross-sectional study in China

OBJECTIVES

The objective of this study was to investigate how kinesiophobia and self-efficacy explain the relationship between fatigue and physical activity (PA) in post-coronary artery bypass grafting (post-CABG) patients over the age of 45.

DESIGN

A prospective multicentre and cross-sectional study.

SETTING

The study was conducted in four public tertiary hospitals in China.

PARTICIPANTS

A total of 1278 patients who underwent CABG surgery were selected from the case pool, with their surgeries occurring between 3 and 19 months prior to selection. Out of 1038 patients who met the inclusion criteria and were invited to participate in the study, 759 patients agreed to participate and complete the questionnaire. Ultimately, 376 questionnaires were deemed eligible and included in the analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

The questionnaire included the following scales: the Chinese version of the Multidimensional Fatigue Inventory (MFI-20), the Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), the Cardiac Exercise Self-Efficacy Instrument (CESEI) and the International Physical Activity Questionnaire-Long (IPAQ-L). A serial mediation model was used to test whether the association between fatigue and PA was mediated by kinesiophobia and self-efficacy, in the overall sample and subsamples defined by age.

RESULTS

The results confirmed that fatigue was directly (95% CI (-5.73 to -3.02)) associated with PA. Higher kinesiophobia (95% CI (-0.16 to -0.05)) or lower PA self-efficacy (95% CI (-0.11 to -0.02)) were parallel pathways through which higher fatigue impediment reduced PA levels. In both subgroups, the street pathways of kinesiophobia and self-efficacy were altered. In the age, 45-60 years group, kinesiophobia (Boot 95% CI (-0.19 to-0.05)) was a mediator of fatigue on PA levels, while in the 61-75 years age group, self-efficacy (Boot 95% CI (-0.17 to -0.04)) was a mediator of fatigue on PA levels.

CONCLUSIONS

A clear relationship between fatigue and PA was mediated by both kinesiophobia and self-efficacy. Furthermore, our findings highlight the importance of adapting the intervention according to the age of the patients, mainly by reducing patients' kinesiophobia in patients aged 45-60 years and increasing patients' self-efficacy in patients aged 61-75 years. It may be possible to improve PA levels in post-CABG patients over 45 years of age by eliminating kinesiophobia and increasing self-efficacy.

Reliability and Validity of a Theory-Based Determinants of Eating and Physical Activity Behaviors Questionnaire for Chinese Elementary School Children

OBJECTIVE

The primary objective of this study was to develop and validate a Social Cognitive Theory-based instrument to identify psychosocial factors that influence diet and physical activity among Chinese children aged 10-12 years.

DESIGN

This is a cross-sectional study, with data collected from questionnaires.

SETTING

Two elementary schools in Beijing, China.

PARTICIPANTS

Fourth to sixth-grade students (N = 1,486) aged 10-12 years were recruited.

VARIABLES MEASURED

Gender, height, weight, nation, and grade were collected. Energy-balanced eating behaviors and their related sociopsychological factors were surveyed.

ANALYSIS

Confirmatory factor analysis, Pearson correlations, Cronbach α index, and mediation analysis were used.

RESULTS

(1) Confirmatory factor analysis revealed a 6-factor solution (51 items) and all factor loadings > 0.32, indicating that the model fitness was acceptable. (2) All correlation coefficients are statistically significant. All of the Cronbach α indexes were > 0.65, indicating acceptable reliability. (3) The mediating effect of goal intention and outcome expectations between self-efficacy and habit strength was statistically significant (P < 0.01), verifying the theory structure.

CONCLUSIONS AND IMPLICATIONS

This questionnaire exhibits good internal consistency, reliability, and structural validity. It can be effectively employed to investigate energy-balanced eating behaviors related to the Social Cognitive Theory in Chinese children.

Change in general and domain-specific physical activity during the transition from primary to secondary education: a systematic review

BACKGROUND

Knowledge of changes in the domains of physical activity (PA) during the transition period from primary to secondary education and the factors associated with these changes, are prerequisites for the design of effective PA promotion strategies. Therefore, the first aim of this study was to systematically review changes in general, leisure-time, school, transport, work, and home PA across the transition from primary to secondary education. The second aim was to systematically review the individual, social, and physical environmental factors that were associated with these changes.

METHODS

Records published up until September 2023 were retrieved from five electronic databases. We included longitudinal and cross-sectional studies that investigated general or domain-specific PA from 2 years before to 2 years after the transition from primary to secondary education. Information on source, study characteristics, sample characteristics, PA, and factors were extracted from the papers included. We reported the direction of change in general and domain-specific PA and the direction of association of the factors with change in general and domain-specific PA.

RESULTS

Forty-eight papers were included in the study. The evidence on changes in PA and associated factors was greatest for general PA. A limited number of the studies investigated the separate domains of leisure-time, school, and transport. Most studies on general and school PA reported a decline in PA, but there were no consistent results for the domains of leisure-time and transport. With respect to the associated factors, evidence was predominantly found for individual factors and to a lesser degree for physical environmental and social environmental factors. None of the factors were consistently associated with changes in general or domain-specific PA during the school transition.

CONCLUSIONS

For the design of targeted PA promotion strategies, further studies are warranted to explore changes in the specific domains of PA across the transition from primary to secondary education, especially in the domains of leisure-time, transport, home, and work PA. In addition, the interactions between factors at different socioecological levels to influence changes in PA need to be addressed more in the future.

Role of physical activity and health-related fitness on self-confidence and interpersonal relations in 14-year-old adolescents from secondary school settings: DADOS study

BACKGROUND

The effect of physical activity (PA) and physical fitness (PF) on self-confidence and interpersonal relations in adolescents is uncertain.

AIM

To analyzed the associations of PA and PF with self-confidence and interpersonal relations in adolescents.

SAMPLE

A total of 268 (138 boys) adolescents (13.9 ± 0.3 years) from the DADOS study were included in the analysis.

METHODS

PA was evaluated using GENEActiv accelerometers and the health-related PF components by the ALPHA health-related fitness test battery. The levels of self-confidence and interpersonal relations were determined by the Behavior Assessment System for Children Level 3.

RESULTS

The associations of PA levels and PF components with self-confidence reported positive associations of moderate-vigorous PA (MVPA), standing long jump, and 20-m shuttle run (shuttle run test) tests (all p < 0.05), and negative association of 4 × 10-m shuttle run test (4 × 10-m test), but only the 4 × 10-m test remained significant in the adjusted model for the whole sample and only in boys (p ≤ 0.01) when analyzed by sex. Regarding interpersonal relations, positive associations of standing long jump and shuttle run test (all p < 0.05), and negative association of 4 × 10-m test were found in all the adolescents. The shuttle run test was associated with interpersonal relations in boys independently of confounders. PA levels were not associated with interpersonal relations.

CONCLUSION

A higher level of lower-limb muscle strength, speed-agility, and cardiorespiratory fitness might improve self-confidence and interpersonal relations in adolescents, but these relationships seem to be influenced by sex, body mass index, and pubertal status. Speed-agility and cardiorespiratory fitness seem to have a stronger impact on boys. MVPA may improve self-confidence in adolescents.

Physical activity maintenance and increase in Chinese children and adolescents: the role of intrinsic motivation and parental support

Objective

This longitudinal study aimed to examine the association of intrinsic motivation, parental physical activity, and parental support with physical activity maintenance and increase among children and adolescents.

Methods

A sample of 2,424 children and adolescents in Shanghai, China participated in the two-wave survey before and during the COVID-19 pandemic. The questionnaire measured children and adolescents' physical activity and intrinsic motivation, as well as their parental physical activity and support (concern for their child and co-activity with their child). Multivariable logistic regressions were performed by groups to examine the associations between these factors and physical activity change.

Results

Most children and adolescents exhibited a decline in physical activity participation during the pandemic, as indicated by a mere 15.0 and 8.0% of individuals maintaining and increasing their pre-pandemic levels, respectively. Among the initially active participants, perceived self-choice [OR = 1.341 (95%CI: 1.173-1.533)] and parental concern [OR = 1.922 (95%CI: 1.204-3.068)] predicted maintained physical activity. Increased physical activity was predicted by perceived enjoyment [OR = 1.193 (95%CI: 1.046-1.362)] and parental co-activity (OR = 1.995 [95%CI: 1.095-3.633]).

Conclusion

This study provides longitudinal evidence that intrinsic motivation and parental support can have a positive impact when physical activity levels change significantly. Effective interventions targeting multilevel factors are needed to maintain or increase children and adolescents' physical activity.

The effects of adapted physical education sessions on the empathy of female students with overweight

The global prevalence of childhood and adolescent overweight and obesity increases rapidly. Physical activity plays a major role in the prevention of obesity. The present study aimed to analyze the effect of adapted basketball sessions according to the empathic capacity of adolescent girls with overweight. Forty-two girls with overweight (age: 16.09 ± 0.85; years; height: 1.64 ± 0.67 m: weight: 73.02 ± 0.61 kg; BMI: 27.15 ± 1.37) volunteered to participate in the study and were randomly assigned to the experimental group (EG, n = 21) and control group (CG, n = 21). EG was submitted to a basketball intervention adapted to students with obesity while the CG performed classic basketball exercises for 7 weeks. Each week girls had 2 basketball teaching-learning sessions, lasting 50 min. The participants' empathy was assessed before and after the intervention using the Favre CEC. The results showed that adaptation intervention was associated with a significant emotional contagion decrease (Δ% = 0.466) and splitting with emotions (Δ% = 0.375), and with an empathy increase (Δ% = 1.387), in EG compared to CG. No significant difference was assessed in the empathy CG, before and after the intervention. This study demonstrated that adapted physical education classes could be an effective strategy to improve empathetic skills and inclusion of overweight girls as well as a means to prevent obesity.

Physical Activity, Sleep, and Demographic Patterns in Alaska Native Children and Youth Living in Anaktuvuk Pass

Physical activity (PA), sleep, and weight are important factors for youth health. However, data about these factors are unknown in youth living in isolated Alaska Native communities. This study aims to assess PA, sleep, height and weight in elementary through high school students living in Anaktuvuk Pass. Fourteen children (<12) and 24 youths (12-20) volunteered to participate in this study. PA and sleep data were collected with actigraphy. Height and weight were assessed with standard procedures. Demographics were collected via survey. Results show that 10.53% and 18.42% of participants were overweight and obese, respectively. Average bedtime was 00:15 am and wake time 08:23 am. Total sleep time was 498.21 min. Participants averaged 477.64 min in sedentary activity, 297.29 min in light activity, 150.66 min in moderate activity, and 18.05 min in vigorous activity. Adjusted models suggest that high school students engage in significantly more sedentary activity, and significantly less light, moderate, and vigorous activity compared to those in middle and elementary school. All students engaged in less moderate and vigorous activity on the weekend compared to the weekday. Data suggest that as children age they become more sedentary. Future studies should focus on increasing daily PA in high school students while considering other obesogenic factors.

Factors Related to Adolescents' Participation in Organized Sports

Participation in organized sports has important health benefits in adolescence, yet participation rates are concerning. A better understanding of factors influencing adolescents' participation in organized sports offers opportunities to improve participation rates. The aim of this study was to examine to what extent motives, perceived competence, encouragement and motor skills were associated with participation in organized sports in a sample of first-year secondary school students. In this cross-sectional study, data were collected from 386 Dutch adolescents (11-14 years) in October and November 2020. A series of multilevel logistic regression models estimated the likelihood of adolescents' participating in organized sports. First, we examined whether motives, perceived competence, encouragement and motor skills were independently associated with the likelihood of participation. Second, we examined whether these factors were concurrently associated with the likelihood of participation. When considered individually, motives, perceived competence, encouragement and motor skills were significantly associated with participation. When considered together, only motives were significantly associated with participation and the associations of all other factors with sport disappeared. These findings show the importance of motivation for participation in sports over other factors. These findings inform the development of interventions aimed at improving adolescents' participation rates.

A Summary of One Research Team's Contributions to Understanding Physical Activity Behavior in Children and Youth

Schools are well-positioned to provide physical activity opportunities to help youth achieve the recommended 60 or more daily minutes of moderate-to-vigorous physical activity. The Children's Physical Activity Research Group (CPARG) at the University of South Carolina has focused on understanding physical activity in school-aged youth for 30+ years. The purpose of this article was to critically review (CPARG) contributions to the field in school settings and school-age youth. We reviewed 127 published CPARG articles from six research projects conducted between 1993-2019. The review was guided by questions in five categories: measurement of physical activity and its determinants, characteristics of physical activity behavior, correlates/determinants of physical activity, physical activity interventions, and race/ethnicity and physical activity. Results were summarized by question and synthesized across categories. CPARG contributions included assessing physical activity levels, patterns, forms, and contexts; identifying and measuring physical activity correlates/determinants; and conducting school-based physical activity interventions. Identifying multiple domains of physical activity determinants enables researchers and practitioners to select/design age-appropriate, valid, and reliable instruments to assess determinants. Focusing on determinants enables them to create effective physical activity interventions, environments, programs, and policies in schools. These efforts must address race/ethnicity differences, ensuring that measurement instruments and intervention strategies are culturally appropriate.

Can Enjoyment and Physical Self-Perception Mediate the Relationship between BMI and Levels of Physical Activity? Preliminary Results from the Regional Observatory of Motor Development in Italy

Physical education during adolescence, supported by evidenced-based methodologies, offers many different opportunities to practice structured physical activity and promote the development of motor skills, motor coordination, and conditioning. The present study aimed to assess differences in the levels of physical activity, enjoyment, and self-perception in a sample (n = 1029, M = 505, F = 524) of 11-12-year-old secondary schoolchildren according to gender and BMI and determine (a) the mediation effects of physical self-perception in the association between BMI and physical activity and (b) the role of enjoyment in mediating the relation between physical self-perception and physical activity. As part of the Regional Observatory of Motor Development Project (Apulia, Southern Italy), the assessment involved three questionnaires for physical activity levels (PAL), physical self-perception (PSP_C), and enjoyment (PACES). The results showed significant differences in PSP between normal-weight, overweight, and obese children (especially in girls), while there were no significant differences in enjoyment. Physical self-perception partially mediates the relationship between BMI and PAL (R2 = 7.94% for males, 95% C.I.: -0.013, -0.004; R2 = 14.70% for females, 95% C.I.: -0.25, -0.009), and the enjoyment partially mediates the relationship between physical self-perception and PAL (R2 = 6.83% for males, 95% C.I. = 0.003, 0.012; R2 = 13.45% for females, 95% C.I. = 0.002, 0.014). However, only a small percentage of variance was explained, precluding the extension and generalization of the results obtained.

The Current Health Belief of Exercise Conditions of Chinese College Students and Ways of Improvements: An Analysis Based on the Health Belief Model

The purpose of this study was to discuss the differences in the parameters of exercise health beliefs among college students of different genders, and assess the relationship between demographic factors and parameters of exercise health beliefs, and examine the relationship between exercise self-efficacy and internal components of exercise health beliefs. A total of 313 Chinese college students from the Sichuan University of Arts and Science completed the exercise health belief scale voluntarily under the tutor’s explanation. The results showed that compared with female students, male students have higher perceived benefits and self-efficacy of exercise and lower perceived subjective and objective barriers. Monthly family income has a significant positive correlation with exercise self-efficacy and a negative correlation with perceived subjective barriers to exercise disorder. Exercise self-efficacy has a positively correlated with perceived benefits and perceived severity and a significant negative correlation with perceived subjective and objective barriers. From the structural equation model, we found that family income no longer significantly impacted exercise self-efficacy. Within the exercise health belief items, we found only that there were negative relationship between perceived subjective barriers and exercise self-efficacy. According to the study, our findings provide a new psychological angle for understanding the exercise condition of college students and the restraining factors and provide new insights into increasing exercise self-efficacy to lower the subjective barriers to exercise. Future studies will focus on evaluating the relationship between exercise health belief components and college Students’ physical activity levels and exercise behaviors.

The role of anesthesiologists' perceived self-efficacy in anesthesia-related adverse events

BACKGROUND

Self-efficacy, as the vital determinant of behavior, influencing clinicians' situation awareness, work performance, and medical decision-making, might affect the incidence of anesthesia-related adverse events (ARAEs). This study was employed to evaluate the association between perceived self-efficacy level and ARAEs.

METHODS

A cross-sectional study was performed in the form of an online self-completion questionnaire-based survey. Self-efficacy was evaluated via validated 4-point Likert scales. Internal reliability and validity of both scales were also estimated via Cronbach's alpha and validity analysis. According to the total self-efficacy score, respondents were divided into two groups: normal level group and high level group. Propensity score matching and multivariable logistic regression were employed to identify the relationship between self-efficacy level and ARAEs.

RESULTS

The response rate of this study was 34%. Of the 1011 qualified respondents, 38% were women. The mean (SD) age was 35.30 (8.19) years. The Cronbach's alpha of self-efficacy was 0.92. The KMO (KMO and Bartlett's test) value of the scale was 0.92. ARAEs occurred in 178 (33.0%) of normal level self-efficacy group and 118 (25.0%) of high level self-efficacy group. Before adjustment, high level self-efficacy was associated with a decreased incidence of ARAEs (RR [relative risk], 0.76; 95% CI [confidence interval], 0.62-0.92). After adjustment, high level self-efficacy was also associated with a decreased incidence of ARAEs (aRR [adjusted relative risk], 0.63, 95% CI, 0.51-0.77). In multivariable logistic regression, when other covariates including years of experience, drinking, and the hospital ranking were controlled, self-efficacy level (OR [odds ratio], 0.62; 95% CI, 0.46-0.82; P = 0.001) was significantly correlated with ARAEs.

CONCLUSIONS

Our results found a clinically meaningful and statistically significant correlation between self-efficacy and ARAEs. These findings partly support medical educators and governors in enhancing self-efficacy construction in clinical practice and training.

The impact of physical fitness on resilience to modern life stress and the mediating role of general self-efficacy

Substantial evidence shows that physical activity and fitness play a protective role in the development of stress related disorders. However, the beneficial effects of fitness for resilience to modern life stress are not fully understood. Potentially protective effects may be attributed to enhanced resilience via underlying psychosocial mechanisms such as self-efficacy expectations. This study investigated whether physical activity and fitness contribute to prospectively measured resilience and examined the mediating effect of general self-efficacy. 431 initially healthy adults participated in fitness assessments as part of a longitudinal-prospective study, designed to identify mechanisms of resilience. Self-efficacy and habitual activity were assessed in parallel to cardiorespiratory and muscular fitness, which were determined by a submaximal step-test, hand strength and standing long jump test. Resilience was indexed by stressor reactivity: mental health problems in relation to reported life events and daily hassles, monitored quarterly for nine months. Hierarchical linear regression models and bootstrapped mediation analyses were applied. We could show that muscular and self-perceived fitness were positively associated with stress resilience. Extending this finding, the muscular fitness-resilience relationship was partly mediated by self-efficacy expectations. In this context, self-efficacy expectations may act as one underlying psychological mechanism, with complementary benefits for the promotion of mental health. While physical activity and cardiorespiratory fitness did not predict resilience prospectively, we found muscular and self-perceived fitness to be significant prognostic parameters for stress resilience. Although there is still more need to identify specific fitness parameters in light of stress resilience, our study underscores the general relevance of fitness for stress-related disorders prevention.

Longitudinal association of biological maturation with physical activity behaviors in girls transitioning from 5th to 7th grade

Introduction

This longitudinal study determined if social cognitive variables influence physical activity in girls stratified on the basis of maturity status.

Methods

Participants attended South Carolina public schools (Mage in 5th grade = 11.1 years) and included a cohort of 529 girls who provided physical activity data in the 5th grade and in 6th and/or 7th grade. The measure of maturity status was age at peak height velocity (APHV) estimated from maturity offset when the children were in the 5th grade. The Earlier Maturity (EM) group included girls whose APHV was one standard deviation or more below the mean APHV for the full sample. All other girls were placed in the Later Maturity (LM) group. Physical activity was assessed at each time point via accelerometry. Social‐cognitive variables were assessed at each time point by a questionnaire measuring self‐efficacy, enjoyment, competence, appearance, fitness, and social motives for physical activity. Growth curves for the total, Earlier Maturing, and Later Maturing groups assessed relationships between physical activity over time and time‐varying social cognitive variables.

Results

Physical activity was lower in the Earlier Maturing group and was positively associated with self‐efficacy and enjoyment motivation in the total group. These relationships were observed in the 5th grade and maintained through 7th grade. In the Later Maturing group, we observed positive relationships between physical activity and self‐efficacy, enjoyment and competence motivation.

Conclusions

Strategies to increase confidence, skills, and enjoyment of physical activity may only be effective for promoting activity among later maturing girls.

The Influence of Physical Education on Self-Efficacy in Overweight Schoolgirls: A 12-Week Training Program

The purpose of this randomized controlled study was to investigate the impact of a 12-week physical education (PE) program on the self-efficacy of overweight schoolgirls. We randomly assigned 60 overweight schoolgirls (15–17 years) to either an experimental moderate to vigorous aerobic exercise (∼90 min, three times a week) group (n = 30) or a control group (CG) (n = 30) that received non-specific regular PE lessons with activities chosen by the curricular teacher mainly focused on team games and sports skills that aimed to achieve general psycho-physical wellness (∼90 min, three times a week). To assess the starting level of students and significant changes reached, at baseline and after training, a battery of standardized assessment motor tests and a psychometric scale (generalized self-efficacy scale, GES) were administered. At the end of the intervention, the experimental group reported a considerable decrease in body mass index (BMI) and a large improvement in self-efficacy (p < 0.001). No significant changes were found in the CG. The results suggested that the 12-week moderate to a vigorous aerobic exercise program is an effective weight loss intervention and a vehicle to promote a range of outcomes important to the qualitative growth of adolescents. In fact, it could provide a positive and significant impact on the self-efficacy of overweight schoolgirls.

Inadequate Mental Health Literacy and Insufficient Physical Activity Potentially Increase the Risks of Anxiety and Depressive Symptoms in Chinese College Students

Objective: The present study aimed to examine the interactive associations between physical activity and mental health literacy with anxiety and depressive symptoms in Chinese college students. Methods: A cross-sectional study was conducted from May to July 2020. A total of 7,512 students were recruited from two medical colleges in Hefei and Anqing city in Anhui Province, China. Physical activity, mental health literacy, anxiety and depressive symptoms were measured by self-reported validated instruments. Analyses were conducted with logistic regression models. Results: The prevalence of anxiety and depressive symptoms was 8.6% and 16.4%, respectively. Insufficient physical activity was significantly associated with depressive symptoms (OR = 1.359, 95%CI 1.184-1.561) and anxiety symptoms (OR = 1.492, 95%CI: 1.237-1.799). Inadequate mental health literacy was significantly associated with depressive symptoms (OR = 3.089, 95%CI: 2.607-3.662) and anxiety symptoms (OR = 3.675, 95%CI: 2.861-4.721). Low physical activity rank (OR = 1.438, 95%CI: 1.151-1.798) was significantly related with depressive symptoms but not anxiety symptoms. The students who had inadequate mental health literacy and insufficient physical activity had the highest risks of depressive symptoms (OR = 5.049, 95% CI: 3.649-6.987) and anxiety symptoms (OR = 5.270, 95% CI: 3.338-8.321). Conclusion: These finding indicated that Chinese college students having insufficient physical activity and inadequate mental health literacy are at risk of exhibiting anxiety and depressive symptoms. Early intervention programs for college students with mental health problems should be considered to enhance their mental health literacy and to increase their physical activities.

Are Self-Efficacy and Perceived Environmental Characteristics Determinants of Decline in Physical Activity Time?

CONTEXT

This study analyzed whether self-efficacy (SE) and perceived environmental characteristics (EC) are determinants of the decline in physical activity (PA) time in adolescents.

METHODS

This used longitudinal observational approach, with 4 years of data collection, involving 355 adolescents (57.7% girls and 42.3% boys), average age of 11.8 years (0.1 y), from João Pessoa, Paraiba, Brazil. SE and EC were measured by scales and PA by a questionnaire. Ordinal logistic regression was used to associate SE and EC with a decline in PA.

RESULTS

There was a linear trend toward a decrease in average PA duration (58.3 [13.7] min/wk/y) and a rise in average access to places for PA (point per year) (0.6 [0.1]), urban safety (0.2 [0.1]), and traffic safety scores (0.5 [0.1]). The results of multivariable analysis indicated that SE and EC were not associated with the decline in PA.

CONCLUSION

There was a decline in PA time, and SE and perceived EC were not determinants of this decline.

Sex-Stratified Trends in Meeting Physical Activity Guidelines, Participating in Sports, and Attending Physical Education Among US Adolescents, Youth Risk Behavior Survey 2009-2019

BACKGROUND

During the past decade, guidelines for youth aerobic and muscle-strengthening physical activity remained unchanged. Active People, Healthy NationSM highlighted school and youth strategies (eg, sports and physical education [PE]) to increase physical activity. Sex, grade, and race/ethnicity disparities exist. This study examines sex-specific trends and differences by grade and race/ethnicity for the prevalence of 5 youth physical activity behaviors from 2009 to 2019.

METHODS

The national Youth Risk Behavior Survey assesses adolescents (grades 9-12) meeting the aerobic, muscle-strengthening, and both guidelines (2011-2019) and sports participation and daily PE (2009-2019). Sex-stratified logistic regression assessed trends and 2009 or 2011-2019 differences by grade and racial/ethnic subgroups.

RESULTS

Decreases in meeting the aerobic, muscle-strengthening, and both guidelines were observed for nearly all male subgroups by grade and race/ethnicity, whereas female subgroups exhibited declines or no change to low prevalence. Sports and PE participation remained mostly constant; select subgroups showed decreases (ie, Hispanic males [sports]; Black males and ninth-grade females [PE]).

CONCLUSIONS

Past decade prevalence and patterns suggest that school-based and other strategies for all adolescents and tailored interventions for sex-specific subgroups may be needed to supplement sports and PE in promoting high school youth physical activity.

Factors Predicting Physical Activity and Sports Participation in Adolescence

Physical activity is important for children's health and wellbeing, yet participation declines across teenage years. It is important to understand the mechanisms that could support adolescents to maintain physical activity participation. The aim of this study was firstly to examine change in sports and nonsports activities over two years during adolescence. Secondly, we explored possible predictors of physical activity and sports participation after two years. Method. A longitudinal cohort study was conducted between 2011 and 2013. Our data were collected from 1225 Norwegian adolescents who were followed over a two-year period, from 6th to 8th grade (11 to 13 years) and from 8th to 10th grade (13 to 15 years). We examined the relations between physical activity and predictors such as peer support, parent support, socioeconomic status (SES), attitude towards physical education, active transportation to school, self-rated health, body image, and change of nonsports activities. We used linear regression analyses and binary logistic regression to explore possible predictors of physical activity and sports participation after two years. Results. We found a significant reduction in sports participation during early adolescence, most pronounced, from 8th to 10th grade (from 13 to 15 years). Factors which predicted physical activity after two years were a positive attitude towards physical education, perceived support from parents, if the student travelled to school in an active way (by walk or bicycle) and also how the student rated his/her own health. The last three factors also predicted improvements of physical activity during the two years. Possible predictors of persisting or starting doing sports were increasing levels of self-rated health, increasing socioeconomic status, whereas increasing engagement in nonsports activities predicted reduced participation in sports. Conclusion. Health promotive efforts aiming at increasing active school transportation, parental support, and subjective health seem important for maintenance of physical activity and sports participation during adolescence. Attitudes may improve by adapting physical education to individual needs and interests and can function as an additional promotive factor.

Social network support and risk factors for obesity and overweight in adolescents

AIM

To determine the relationship between social support in social networks and risk factors of overweight and obesity including healthy lifestyles and perceived barriers in adolescents.

METHOD

Descriptive and cross-sectional study with adolescents from a public high school in Nuevo León, Mexico. Anthropometric measurements were determined to obtain body mass index, behavioural measurements for perceived barriers to healthy eating and physical activity, as well as healthy lifestyles.

RESULTS

A total of 188 adolescents participated, male sex predominated at 55.9%, mean age was 16.1 years. From them, 52.1% were overweight, less than half of the adolescents reported having friends on social networks (37.8%); 52% of overweight participants need changes in their diet and the majority reported low physical activity (82.7%). There is a correlation between social support in social networks and perceived barriers to physical activity in overweight adolescents (r₂ 0.144; p < 0.05).

CONCLUSIONS

Most of the adolescents do not have an adequate diet or perform recommended physical activity, one of the main causes is lack of motivation as a perceived barrier. Social networks represent a tool for nursing staff to promote health and develop interventions aimed at preventing disease in a global context in digital transition.

PSYCHOSOCIAL ASPECTS OF PHYSICAL ACTIVITY: DATA ON BRAZILIAN ADOLESCENTS

ABSTRACT Introduction Although the benefits of regular physical activity (PA) for adolescents are well-described in the literature, there is little evidence of the role of psychosocial aspects on levels of PA in this population. Objective To investigate the prevalence and sociodemographic factors associated with enjoyment of PA and preference for leisure-time activities in boys and girls. Methods A cross-sectional study, with 6529 adolescents (aged 15 to 19 years) enrolled in secondary education in public schools in the South of Brazil. Logistic regression was used to analyze the association between sociodemographic factors and the variables of interest, with data collection using a standardized questionnaire. Results Boys enjoyed (87.1%) and preferred (44.4%) PA more than girls (enjoyment: 79.2%; preference: 29.5%). Among the boys, enjoyment was associated with family income(OR3-5 wages=1.53; OR≥6 wages=1.62) and, among the girls, it was associated with age (OR19 years=0.28), occupational status (ORworkers=1.45), and income (OR3-5 wages=1.35). Preference was associated with age (OR19 years=2.48) and income (OR≥6 wages=0.70) among the boys and, among girls, it was associated with area of residence (ORrural=1.47) and occupation (ORworkers=1.31). Conclusion Boys (enjoyment: 87.1%; preference: 44.4%) had more positive attitudes toward PA than girls (enjoyment: 79.2%; preference: 29.5%), and some sociodemographic variables appear to be more closely associated with these attitudes than others. Enjoyment was associated with family income for boys, and with age, occupation and income for girls. Preference, in turn, was associated with age and family income for boys, and area of residence and occupational status for girls.

Expectancy-Value Model Related to Physical Activity Behaviors in Chilean and Spanish Adolescents

The purpose of the study is to comparatively test the expectancy-value model in Chilean and Spanish samples. The model proposes: a social world (composed of social support, physical activity teasing, and weight teasing), expectancy (composed of perceived competence and appearance), task values (composed of enjoyment and stress) to predict physical activity and intention to be physically active. Participants were 497 (Chilean) and 1365 (Spanish) adolescents. Structural equation models and multi-group modelling were used. All the models presented adequate fit to the data. The results show that physical activity teasing is a contextual and essential variable; perceived competence and enjoyment influenced physical activity and intentions to be physically active; some differences appeared in the prediction of physical activity and intentions to be physically active when the multi-group model was run. Culturally tailored interventions are key to improving physical activity (PA) behaviors.

The Relationship Between Self-Regulatory Efficacy and Physical Activity in Adolescents With a Caveat: A Cross-Lag Design Examining Weather

PURPOSE

The use of self-efficacy to predict physical activity has a long history. However, this relationship is complex, as self-efficacy is thought to influence and be influenced by physical activity. The directionality of the self-regulatory efficacy (SRE) and physical activity relationship was examined using a cross-lagged design. A secondary purpose was to examine these relationships across differing weather conditions.

METHODS

Canadian adolescents (N = 337; aged between 13 and 18 years) completed the physical activity and SRE measures 4 times during a school year. Structural equation modeling was used to perform a cross-lag analysis.

RESULTS

The relationships between physical activity and SRE appeared to be weather dependent. During a more challenging weather period (eg, cold weather), the relationship between physical activity and SRE was bidirectional. However, no relationship emerged when the 2 constructs were assessed during a more optimal weather period (eg, warm weather).

CONCLUSIONS

Some support has been provided for the bidirectional nature of the relationship between physical activity and SRE. The relationship appeared to be qualified by climate considerations, suggesting that future research examine how weather may relate not just to physical activity but also to the correlates of physical activity.

Mediators of physical activity between standard exercise and exercise video games

OBJECTIVE

Exercise video games (EVGs) may offer an attractive, sustainable alternative or supplement to traditional modes of exercise. Understanding the psychosocial factors that influence the appeal of EVGs is important for improving the efficacy of video games as a method of promoting the uptake and long-term maintenance of physical activity.

METHODS

This study examined changes in psychosocial constructs from self-determination theory and self-efficacy theory as mediators of intervention efficacy among 189 healthy, sedentary adults randomized to 12-week programs of either EVGs or standard exercise (e.g., treadmill walking, stationary cycling) followed by 6 months of follow-up. The EVG group engaged in significantly more weekly minutes of moderate to vigorous physical activity (MVPA) at the end of treatment compared with the standard exercise group. Univariate and multivariate mediational models were used to examine theoretically derived psychosocial constructs as potential mediators of differential intervention effects.

RESULTS

Univariate mediational models suggest a significant indirect effect of treatment on MVPA outcomes through enjoyment, self-efficacy, stress management, depressive symptoms, and positive engagement (p < .05). Multiple mediational analyses confirm all the univariate results (p < .05), with the exception of enjoyment.

CONCLUSIONS

Differences in the efficacy of EVG versus standard exercise interventions were mediated by several psychosocial constructs, suggesting that qualities specific to game play may enhance adherence to physical activity both in and outside of the laboratory environment.
