Physical activity and analogue anxiety disorder symptoms and status: Mediating influence of social physique anxiety

The role of differential exposure and susceptibility to heavy drinking linking income inequalities and tooth loss: An investigation of the alcohol harm paradox using a four-way decomposition analysis

OBJECTIVES

To examine the extent to which the effect of income inequalities on tooth loss is attributable to differential exposure and susceptibility to heavy drinking in older Brazilian adults.

METHODS

We conducted a secondary analysis using data from The Brazilian Longitudinal Study of Ageing (ELSI-Brazil 2015-2016), a nationally representative sample of community-dwelling people aged 50 years and over. Causal mediation analysis based on the counterfactual outcome framework decomposed the effect of income on tooth loss mediated by heavy drinking into four components (four-way decomposition): controlled direct effect (neither mediation nor interaction), reference interaction (interaction only), mediated interaction (both mediation and interaction) and pure indirect effect (mediation only). Proportions of effect attributable to each component were calculated to estimate the differential exposure (the sum of the third and fourth components) and differential susceptibility (the sum of the second and third components) to heavy drinking.

RESULTS

The analytical sample comprised 8114 participants. After adjusting for covariates, 7.3% (95% CI: 3.8%; 10.9%) and -39.5% (95% CI: -75.8%; -3.3%) of the effects of income on tooth loss were attributable to differential exposure and susceptibility to heavy drinking, respectively, consistent with the alcohol harm paradox. When setting non-functional dentition as outcome, only the effect of differential susceptibility remained (-81.7% [95% CI: -128.2%; -35.2%]).

CONCLUSION

Our findings suggest that individuals of low-income groups appear to be more susceptible to the effects of heavy drinking on tooth loss.

Using ChatGPT to promote college students' participation in physical activities and its effect on mental health

As one of the most famous large language models, ChatGPT has great potential for application in physical education. It can provide personalized exercise plans, a variety of exercise options, and interactive support. The integration of ChatGPT into the teaching process can promote college students' participation in physical activities and improve their mental health while expanding the traditional teaching environment and promoting the reform of traditional teaching methods. However, the application of ChatGPT faces challenges and obstacles in physical education. To make full use of ChatGPT in physical education, it can be combined with wearable devices and sports equipment to enhance the efficiency of interactions with users. Relevant policies are urgently needed to avoid the improper use of users' data.

Physical activity dose for generalized anxiety disorder & worry: Results from the Irish longitudinal study on ageing

The lowest moderate-to-vigorous physical activity (MVPA) dose that conveys protection for Generalized Anxiety Disorder (GAD) and worry is unknown. This study quantified associations of weekly accumulated MVPA doses with GAD and worry across 10 years using data from The Irish Longitudinal Study on Ageing (TILDA). Continuous MVPA (metabolic equivalent of task [MET] minutes per week [MET.min.week-1]; e.g., moderate-intensity brisk walking = 4METs), three-dose and, more precise, five-dose MVPA categories were examined. Worry symptoms and GAD status were measured using the Penn State Worry Questionnaire-Abbreviated and the Composite International Diagnostic Interview. Multivariable negative random effect binomial regression and logistic models adjusted for relevant covariates quantified associations across time. Among the 7,650 participants, compared to no MVPA (0 MET.min.week-1), 18 % (OR: 0.82; 95 %CI: [0.69-0.98]), 22 % (OR: 0.78; [ 0.64-0.95]) and 31 % (OR: 0.69; [0.59-0.79]) lower odds of GAD were found for the doses of 1-<600, 600-<1,200 and ≥2,400 MET.min.week-1 respectively. Post-hoc analysis demonstrated 47 % lower odds (OR: 0.53; (0.36-0.78) of GAD for 1-<200 MET.min.week1 compared to inactivity. Compared to no activity, engaging in even minimal physical activity equivalent of 10 min/day for five days/week of moderate-intensity activity (e.g., brisk walking), may lower the risk of GAD over time among older adults.

Social Appearance Anxiety Scale: a psychometric investigation and evaluation of the influence of individual characteristics on social appearance anxiety in Brazilian adults who practice physical exercise

Introduction

Evaluating signs of anxiety related to body appearance is becoming increasingly important in contemporary society and, in this sense, the Social Appearance Anxiety Scale (SAAS) seems an interesting alternative of measurement.

Objectives

To evaluate the psychometric properties of the Portuguese version of the SAAS when applied to Brazilian adults who practice physical exercise and verify the influence of individual characteristics on participants' social appearance anxiety.

Methods

This was a cross-sectional study conducted online. The participants completed the SAAS and a demographic questionnaire. The psychometric properties of the SAAS one-factor model were evaluated using confirmatory factor analysis. A structural model was built for men and women to verify the influence of individual characteristics of the participants on social appearance anxiety.

Results

1,495 individuals participated in the study (70.8% women; mean age = 29.5, SD = 8.9 years). The data obtained with the SAAS presented good indicators of validity and reliability for both genders (CFI > 0.97, TLI > 0.97, SRMR = 0.04, α > 0.97, ω > 0.85). For both men and women, greater levels of social appearance anxiety were observed among younger participants, who had a higher body mass index, self-reported an eating disorder, and perceived a change in their body after the onset of the COVID-19 pandemic. For women specifically, higher income and having started physical exercise more recently were associated with greater levels of social appearance anxiety.

Conclusion

The findings supported the validity and reliability of the data obtained with the SAAS and revealed that when investigating social appearance anxiety in future research and clinical protocols, specific individual characteristics should be considered.

Cognitive behavioural techniques reduce exercise anxiety and improve adherence to a resistance training program for people with anxiety-related disorders: A randomized controlled trial

Exercise is a cost-efficient alternative to other interventions for anxiety-related disorders (ARDs; e.g., psychotherapy, pharmaceutical) that is also associated with health benefits. Several exercise modalities, including resistance training (RT), have demonstrated efficacy at reducing symptoms of ARDs; however, there are challenges associated with effectively implementing such protocols, most notably, exercise avoidance or early discontinuation. Researchers have identified exercise anxiety as a contributor to exercise avoidance for people with ARDs. Exercise-based interventions for people with ARDs may need to include strategies for helping these individuals cope with exercise anxiety to facilitate long-term exercise engagement; however, research in this area is lacking. The primary purpose of this randomized controlled trial (RCT) was to examine the effects of combining cognitive behavioural techniques (CBT) with a RT program on changes in exercise anxiety, exercise frequency, disorder-specific anxiety symptoms, and physical activity for people with ARDs. A secondary purpose was to explore group differences in exercise motivation and exercise self-efficacy across time. A total of 59 physically inactive individuals with ARDs were randomized into either RT + CBT, RT, or waitlist (WL). Primary measures were assessed at baseline, weekly during the 4-week active phase, and at 1-week, 1-month, and 3-month follow-ups. Findings indicate both RT and RT + CBT can reduce exercise anxiety; however, the addition of CBT techniques may help facilitate improvements in exercise self-efficacy, reductions in disorder-specific anxiety, and increases in long-term exercise behaviour and vigorous physical activity. These techniques may be useful for researchers and clinicians alike in supporting individuals with ARDs interested in using exercise to cope with elevated anxiety.

Motivational Climate, Anxiety and Physical Self-Concept in Trainee Physical Education Teachers-An Explanatory Model Regarding Physical Activity Practice Time

There is an increase in sedentary lifestyles among young people. However, the development of a certain motivational climate can play a key role in the prevention of such lifestyles. Taking into account the aforementioned, the present research aims to establish the relationship between the motivational climate towards sport, anxiety and physical self-concept and to identify and clarify the existing relationships between anxiety, motivational climate and physical self-concept, by breaking down this objective into (a) developing an explanatory model of the motivational climate towards sport and its relationship with anxiety and physical self-concept and (b) contrasting the structural model by means of a multi-group analysis, according to the time spent doing physical activity per week. For this purpose, a cross-sectional descriptive and comparative study was carried out with a total of 568 university students (M = 25.09; SD = 6.22). A sociodemographic questionnaire, the Spanish version of the Perceived Motivation Climate Questionnaire in Sport, the Self-Concept Form-5 and the Beck Anxiety Inventory were used for data collection. The results show that more time spent doing physical activity brings benefits in terms of physical self-concept and homework climate, helping to reduce anxiety levels. As conclusions, it is observed that a longer time spent doing physical activity brings benefits in the channelling of disruptive states and improvements in physical self-concept.

Research on the Influence of Sports and Nutrition Matching on Improving Students' Physique Based on Intelligent Sensor

With the continuous development of social economy, students' learning is paid more and more attention, but at the same time, their physical condition also deserves attention. In view of these problems and limitations, this paper is based on intelligent sensors, which is different from the traditional physical education teaching, adopts the corresponding prescription for sports teaching, combines teaching with fun for the corresponding health intervention, and realizes the two-way dimensional analysis of compound sports prescription through comprehensive nutrition collocation, so as to improve students' physical and mental health, in order to improve students' physical fitness. The simulation results show that the intelligent sensor is effective, which can improve the systematicness and scientificity of students' participation in exercise in sports activities and improve students' learning and physical fitness.

Social Physique Anxiety Scale: Psychometric Evaluation and Development of a Chinese Adaptation

The Social Physique Anxiety Scale (SPAS) is a popular measure of individual anxiety related to body image. This study assessed the psychometric properties of the 12-, 9-, 8- and 7-item versions of the SPAS. Two cross-sectional studies recruited 466 Chinese university students. Study 1 (n = 273) evaluated the construct validity and internal consistency of the SPAS. Study 2 (n = 193) further assessed the construct validity, factorial validity, internal consistency, convergent validity and divergent validity of the SPAS. The results indicated that none of the existing SPAS versions possess good psychometric properties suitable for the Chinese student population. In short, a new 7-item version of the SPAS that is more suitable for measuring social physique anxiety among Chinese university students. The implications of our results and future research directions are discussed.
