Relationships Among eHealth Literacy, Physical Literacy, and Physical Activity in Chinese University Students: Cross-Sectional Study.

eHealth literacy is critical for evaluating abilities in locating, accessing, and applying digital health information to enhance one's understanding, skills, and attitudes toward a healthy lifestyle. Prior research indicates that enhancing eHealth literacy can improve health behaviors such as physical activity (PA). Physical literacy (PL) refers to the ability to develop sustainable PA habits, taking into account various aspects of an individual. Notably, university students have shown a decline in PA and possess low PL levels. However, the connection between eHealth literacy and PL in this demographic has not been extensively studied, and it remains uncertain whether PA acts as a mediator between eHealth literacy and PL. This study examines the extent to which PA mediates the link between eHealth literacy and PL in Chinese university students and explores gender differences in these variables. In February 2022, a cross-sectional survey was administered to 1210 students across 3 universities in China. The instruments used were the Perceived PL Instrument, the International Physical Activity Questionnaire, and the Chinese version of the eHealth Literacy Scale. Correlations between eHealth literacy, PA, and PL were analyzed using Pearson product-moment correlation and multiple linear regression, while mediation models helped elucidate the interactions among the 3 variables. The response rate for the study was 92.9% (1124/1210). In the mediation analysis, eHealth literacy showed a significant direct effect on PL, with a coefficient of 0.78 (β .75, SE 0.02; P<.001). Moderate to vigorous physical activity (MVPA) accounted for 2.16% of the total effect, suggesting that MVPA partially mediates the relationship between eHealth literacy and PL. Additionally, male students outperformed female students in terms of MVPA (t636=4.94; P<.001) and PL (t636=3.18; P<.001), but no significant differences were found in eHealth literacy (t636=1.23; P=.22). The findings indicate that MVPA serves as a mediator in the link between eHealth literacy and PL among university students. Students with low eHealth literacy or limited PA are less likely to be physically literate. Thus, eHealth literacy plays a crucial role in enhancing PL and PA, especially when interventions targeting PL are implemented. Our results also suggest a need for targeted health education interventions aimed at improving MVPA and PL among female students, while also recognizing that eHealth literacy is comparable across genders at universities.

Effect of habitual physical activity on motor performance and prefrontal cortex activity during implicit motor learning

Background Acute bouts of exercise have been shown to improve motor learning. However, whether these benefits can be observed from habitual physical activity (PA) levels remains unclear and has important implications around PA guidelines to promote motor learning across the lifespan. This study investigated the effect of habitual PA levels on brain activity within the dorsolateral prefrontal cortex (DLPFC) during procedural motor skill acquisition. Methods Twenty-six right-handed healthy young adults had physical activity levels quantified by calculating the metabolic equivalent of task (METs) in minutes per week, derived from the International Physical Activity Questionnaire (IPAQ). Functional near-infrared spectroscopy (fNIRS) over the DLPFC was recorded to measure neural activation during a serial reaction time task (SRTT). Behavioural indicators of procedural motor skill acquisition were quantified as reaction time and accuracy of correct trials during the SRTT. DLPFC activation was characterised as task-related changes in oxyhaemoglobin (∆[HbO2]). Results Findings showed that higher PA levels were associated with improvements in reaction time during procedural motor skill acquisition (p = 0.03). However, no significant effects of PA levels on accuracy or ∆[HbO2] during procedural motor skill acquisition were observed. These findings show that while habitual PA may promote motor performance in young adults, this is not reflected by changes in the DLPFC area of the brain.

The influence of Mediterranean diet and physical activity-related energy expenditure on weight status and cardiometabolic risk. What "weights" more? The HERMEX study.

In this cross-sectional study, we explored the influence of Mediterranean Diet (MD) adherence and physical activity-related energy expenditure on weight status and cardiometabolic risk in a large sample of 2.833 young, middle-aged and older adults. A food frequency questionnaire was employed, and MD Score to assess MD adherence. Physical activity-related energy expenditure was reported through the Minnesota Leisure Time Physical Activity Questionnaire. Anthropometry, blood pressure, lipid and glycaemic markers were measured. Most of the participants were overweight or obese and had a medium-high MD adherence. The obesity group showed lower energy expenditure and a greater clustered cardiometabolic risk. Overweight and obese had a greater clustered cardiometabolic risk compared to the high MD adherence and normo-weight. Obese showed the greatest clustered cardiometabolic risk with independence of MD adherence. Increasing energy expenditure through physical activity better than restrictive diets might be one of the key components for reducing cardiometabolic risk among obese people.

Effect of FTO Gene polymorphism on anthropometric, hemodynamic, and autonomic variables in adolescents

Objective: The study aimed to analyze the influence of physical activity levels and the rs9939609 polymorphism (FTO gene) on anthropometric, hemodynamic, and cardiac autonomic variables in public school students. Methods: A total of 288 students (aged 11 to 18, both sexes) from public schools in São Luís, Maranhão, were divided into four groups: sedentary AA+AT (AA+AT sed), active AA+AT (AA+AT activ), sedentary TT (TT sed), and active TT (TT activ). Evaluations included the International Physical Activity Questionnaire, weight, height, body mass index (BMI), buccal cells collection for DNA extraction, systolic (SBP) and diastolic (DBP) blood pressure measurements, and heart rate variability (HRV) analysis. A chi-square test for allelic associations was applied a 5% significance level. Results: No significant differences were observed in DBP or heart rate (HR). The active groups (AA+AT activ and TT activ) exhibited reductions in weight and METs/min/week compared to their respective sedentary groups (P&lt;0.05). The TT activ group also demonstrated reductions in SBP and BMI compared to the TT sed group (P&lt;0.05). The TT activ group had higher HRV in the RR time domain (ms) compared to the TT sed group (P&lt;0.05), though no significant differences were found in other HRV variables. Conclusions: The FTO gene polymorphism influences cardiac autonomic modulation, while physical activity levels affect anthropometric variables.

Too Many Couch Potatoes Among Middle-Aged Inflammatory Bowel Disease Patients: Findings from the “BE-FIT-IBD-2” Study

Background: Regular physical activity (PA) is desirable, regardless of age, even in patients with chronic conditions such as inflammatory bowel disease (IBD). Aims: This study aims to assess PA levels and related barriers/facilitators in IBD patients, stratifying them into age groups (with a threshold of 50 years). Methods: The International PA Questionnaire (IPAQ) assessed PA levels regarding resting metabolic rate (Met) in minutes per week (min/wk). Patient-reported outcomes 2 (PRO-2) evaluated disease activity. Results: Among the 237 enrolled patients, PA rates were found to differ significantly in terms of patients being sufficiently active (55% vs. 39.8%), inactive (39.6% vs. 59.1%), and engaging in health-enhancing PA (5.4% vs. 1.1%) between patients under and at least 50 years old, respectively (p &lt; 0.001). Overall, PA levels followed this trend, being higher in younger patients [892 (446.5–1439) vs. 545.25 (257–1210.47) Met min/wk, p = 0.007]. Individuals aged at least 50 years tend to have lower PA at regression analysis (OR: 3.302, p = 0.018). Patients aged at least 50 years perceived IBD as more of a barrier to PA (p = 0.04). Bowel urgency is a significant barrier, especially in older patients (p = 0.022). Conclusions: Age is an unmodifiable factor impacting and influencing PA levels. Strategies to recover exercise levels in older IBD patients should be encouraged.

Cognitive Behavioral Therapy for Paroxysmal Atrial Fibrillation: Heart Rate Variability, Physical Activity, and Sleep

BackgroundCognitive behavioral therapy for symptom preoccupation in paroxysmal atrial fibrillation (AF-CBT) significantly improved AF-specific quality of life in a recent trial. To what extent this may this may be associated with changes in physiological parameters is yet to be determined. ObjectivesThe purpose of this study was to assess the effects of AF-CBT on heart rate variability (HRV), physical activity, and sleep. MethodsPatients with symptomatic paroxysmal AF on optimal medical therapy (mean ± standard deviation 65.4 ± 8.3 years, 58% females, 61% on beta-blockers) were randomized to a 10-week online AF-CBT (n = 65) or AF education (n = 62). AF-CBT was therapist-led and focused on social and physical avoidance. A 5-day Patch-Holter with an integrated accelerometer was applied at baseline, post-treatment, and at 3-month follow-up to assess AF burden, HRV, physical activity, and sleep duration. Subjective assessments were made by the International Physical Activity (IPAQ) and Insomnia Severity Index questionnaires. ResultsAt baseline, participants walked on average 8040 ± 2600 steps/day and slept 8.0 ± 1.1 hours. Objective and subjective physical activity and sleep duration remained unchanged after treatment, with no significant difference between the groups. The Insomnia Severity Index score went from subclinical insomnia (12.2 ± 6.7) to near normal values (8.1 ± 5.6), a significant change compared to controls (P = 0.032). No changes were found in AF burden or HRV indices at rest during the day or at night. ConclusionsIn this select cohort, AF-CBT decreased insomnia severity but had no impact on HRV or physical activity. Thus, AF-CBT may operate through psychological and behavioral factors that are not targeted by current medical and lifestyle interventions.

The influence of physical activity, interpersonal intelligence, emotional intelligence on physical education academic achievement of elementary school students

Background and Study Aim. Physical Education not only develops physical aspects but also critical thinking, reasoning skills, and affective aspects, including social skills and personal traits like caring and cooperation. The study aims to examine the effect of physical activity, interpersonal intelligence, and emotional intelligence on the academic achievement of Physical Education Elementary School Students. Materials and Methods. The research uses a quantitative, correlational approach. The study population consisted of 102 elementary school students aged 9-12 years (54 males, 48 females). The physical activity instrument used was the Physical Activity Questionnaire for Children (PAQ-C). The interpersonal intelligence instrument was adapted from the Anderson Social Insight, Social Sensitivity, and Social Communication dimensions. The emotional intelligence instrument was the “Emotional Quotient Inventory: Young Version (EQ-i: YV). The statistical analysis was conducted using SPSS (Statistical Package for Social Science) version 21 software. The level of statistical significance was set at p-value &lt;0.05. Results. The results showed that: (1) physical activity has a significant effect on the physical education academic achievement of elementary school students (p-value 0.006 &lt;0.05). (2) Interpersonal intelligence has a significant effect on the academic achievement of physical education elementary school students, (p-value 0.000 &lt;0.05). (3) Emotional Intelligence has a significant effect on physical education academic achievement of elementary school students, (p-value 0.005 &lt; 0.05). Conclusions. In particular, learners who exercise show greater intrapersonal and emotional intelligence, adaptability, and mood compared to those who do not exercise in an organized way. Physical education teachers are expected to assign physical activities for students to complete at home under parental supervision, with the results reported to the teacher for an additional assignment grade.

Investigation of personality type and physical activity level in physiotherapy and rehabilitation department students

Aims: The aim of this study is to examine the relationship between personality types and physical activity levels among undergraduate students in the department of physiotherapy and rehabilitation. Methods: The participants’ physical activity levels were assessed using the short form of the International Physical Activity Questionnaire (IPAQ). To evaluate the participants’ personality traits, the Eysenck Personality Questionnaire-Revised/Short Scale was used. The relationship between individuals’ personality traits and physical activity levels was determined using Spearman’s rank correlation analysis. Results: The study included 180 undergraduate students from the department of physiotherapy and rehabilitation. The results revealed a strong correlation between severe metabolic equivalent (MET) (r: 0.246, p: 0.001), moderate MET (r: 0.196, p: 0.009) and total MET (r: 0.202, p: 0.007) with psychoticism. Additionally, a strong correlation was observed between extraversion and walking MET (r: 0.180, p: 0.017) as well as total MET (r: 0.196, p: 0.009). Conclusion: Students with personality traits of psychoticism and extraversion tend to be physically more active.This study shows that physical-activity levels may be predicted by personality traits on Turkish physiotherapy and rehabilitation students.

Kinect-Based Mixed Reality Exercise Program Improves Physical Function and Quality of Life in Breast Cancer Survivors: A Randomized Clinical Trial.

Exercise is an effective non-pharmacological approach for alleviating treatment-related adverse effects and enhancing physical fitness in breast cancer survivors. A Kinect-based mixed reality device (KMR), with real-time feedback and user data collection, is an innovative exercise intervention for breast cancer survivors. This study aimed to investigate the effect of KMR exercise program on quality of life (QOL) and physical function in breast cancer survivors. Seventy-seven participants were randomly assigned to either the KMR exercise group or home stretching group with an 8-week intervention. Physical function (shoulder range of motion [ROM], body composition, aerobic capacity, and hand grip strength) was evaluated before and after the intervention period. Participants completed questionnaires such as the Disabilities of the Arm, Shoulder, and Hand (DASH), Functional Assessment of Cancer Therapy-Breast, and International Physical Activity Questionnaire (IPAQ) to assess upper extremity disabilities, QOL, and physical activity levels. Significant group-by-time interaction was found for flexion of the operated arm (154.3±12.5 to 165.8±11.2), and the non-operated arm (158.2±13.8 to 166.5±12.2), abduction of the non-operated arm (154.8±31.6 to 161.1±28.1), and adduction of the operated arm (46.5±9.1 to 52.6±7.2). Significant improvements were also observed in DASH (46.8±9.1 to 40.8±9.3) and IPAQ (1136.3±612.8 to 1287±664.1). The KMR exercise program effectively improved the physical function, alleviated edema, reduced upper extremity disability, and enhanced the QOL in breast cancer survivors. Coupled with significant group-by-time interactions for various outcomes, the results emphasize the potential benefits of incorporating the KMR exercise program to improve the QOL in breast cancer survivors.

Exploring the physical activity levels of egyptian women with premenstrual syndrome: a preliminary study

Background and Study Aim. Premenstrual syndrome (PMS) affects a significant proportion of women, impacting their daily lives and well-being. The association between physical activity levels, the prevalence of premenstrual syndrome (PMS), and the severity of PMS remains debatable. Therefore, this study aimed to identify physical activity levels among a cohort of Egyptian females with PMS. Material and Methods. This study included one hundred females with PMS. Physical activity levels, anaerobic power, aerobic capacity, BMI, and dysmenorrhea were investigated. PMS severity was assessed using the Premenstrual Syndrome Scale (PMSS), and the females' physical activity was evaluated using the International Physical Activity Questionnaire (IPAQ). The 1-mile submaximal test and the Running-Based Anaerobic Sprint Test (RAST) were used to assess aerobic capacity and anaerobic power, respectively. Results. The findings revealed a significant association between PMS severity and physical activity (p &lt; 0.05). There was no significant difference in aerobic capacity among those with mild, moderate, and severe PMS (p &gt; 0.05). There was no significant association between PMS severity and marital status (p &gt; 0.05), whereas there was a significant association with dysmenorrhea (p &lt; 0.05), especially among moderate and severe PMS sufferers. Females with severe PMS had a significantly higher BMI than those with mild PMS (p &lt; 0.05) and those with moderate PMS (p &lt; 0.05). Mild and moderate PMS females showed no significant difference in BMI (p &gt; 0.05). Conclusions. It can be concluded that physical activity levels and BMI may affect PMS. Therefore, being physically active and maintaining a normal-range BMI might reduce PMS severity.

Bidirectional association between physical activity and depression: the “Como Vai?” cohort study

To evaluate bidirectional and longitudinal association between physical activity (PA) and depressive symptoms (DS). This is a cohort study called “Como Vai?” (How are you?), conducted by older population representative sample of the city of Pelotas-Rio Grande do Sul. The analyses used data from the first interview (2014) and follow-up (2019/20). The long version of the International Physical Activity Questionnaire (IPAQ) was applied to assess PA in the leisure, commuting and total domains. The presence of DS was measured using the Geriatric Depression Scale (GDS-10). Linear regression models were used to evaluate bidirectional associations between PA and DS. Analytical sample included 515 individuals with a mean age of 70.7 (± 9.2) years. Each weekly minute of total PA (β: -0.0006; 95% CI: -0.0011; -0.0001) and commuting PA (β: -0.0008; 95% CI: -0.0016; -0.0001) in 2014 predicts worse DS scores in 2019/20. At the same time, DS score in 2014 (β: -9.79; 95% CI: -18.81; -0.76) was a negative predictor of leisure-time PA in the 2019/20 follow-up adjusted for sociodemographic and other health behaviors. However, when adjusted for the respective outcomes at baseline, the associations found were not statistically significant. The present study did not find evidence of bidirectionality between PA and DS and the prospective associations lost statistical significance after adjustment for the respective outcomes at baseline. Other investigations are necessary including more periods of follow-up, objective analyses of PA to complement analyses by domains and, therefore, provide a better understanding of this complex relationship.

Shaping childhood obesity: behavioral and environmental risk factors associated with body mass index trajectories between 2 and 9 years in Samoan children.

Pacific children are at high obesity risk, yet the behavioral and environmental factors that contribute to obesity development in this setting remain poorly understood. We assessed associations between childhood risk factors for obesity with body mass index (BMI) trajectories between ages 2-9 years in Samoa. In a prospective cohort of 485 children from 'Upolu, we measured weight and height at ages 2-4 (2015), 3.5-8 (2017-18), and 5.5-11 years (2019-20). Modern dietary pattern adherence was assessed using factor analysis of primary caregiver-reported food frequency questionnaire data. Physical activity was estimated with the Netherlands Physical Activity Questionnaire. Socioeconomic resources were assessed using an 18-item household asset score. Urbanicity was based on village residence. Associations of these risk factors with predicted weight, height, and BMI (at 1-year intervals and velocity) were assessed using multilevel cubic spline regressions. Females had greater adjusted weight velocity with high modern dietary pattern adherence compared to low (p-value for interaction with age spline term 1 = 0.028 and age spline term 2 = 0.007). Starting at age 3 years, children with higher physical activity had higher BMI, but this association was not meaningful up to age 9 (all p-value > 0.05). Males with very high compared to low household assets had higher BMI from age 2 to 4 years (95% CI: 0.26-1.53 kg/m2, p = 0.006) and greater BMI velocity (p-value for interaction with age spline term 2 = 0.001). Males in the urban region had the greatest BMI gain after age 5 compared to the rural region (p-value for interaction with age spline term 2 = 0.014). High, centile-crossing BMI trajectories suggest that obesity prevention and intervention are needed among Samoan children before age 9 years. Positive associations between high modern dietary pattern adherence, greater asset ownership, and urbanization offer initial insights into who, and which behavioral risk factors, should be prioritized in implementing public health solutions.

Prevalence and severity of sarcopenia in patients on maintenance hemodialysis: a cross-sectional study

BackgroundSarcopenia, the progressive loss of muscle mass and strength, is common among patients with chronic kidney disease, especially those on maintenance hemodialysis. This condition often arises from factors like reduced physical activity and metabolic changes associated with chronic kidney disease. This study aims to assess the prevalence and severity of sarcopenia in patients on maintenance hemodialysis (MHD), focusing on probable sarcopenia and its correlations with physical activity, body mass index, and inorganic phosphorus levels.MethodsThis cross-sectional study involved 220 patients on MHD who visited to West China Hospital of Sichuan University between February and April 2023. The demographic data, body measurements, and laboratory results were retrospectively collected. Sarcopenia was assessed using the 2019 criteria from the Asian Working Group and the European Working Group on Sarcopenia in Older People, and physical activity was measured via the International Physical Activity Questionnaire.ResultsOf the study participants, 141 (64.1%) were diagnosed with probable [110 (50.0%) or confirmed sarcopenia [31 (14.1%)], including 22 (10%) with severe sarcopenia. Multivariable logistic regression analysis revealed that physical activity (International Physical Activity Questionnaire score, OR = 0.998, 95% CI: 0.998–0.999, P < 0.001), body mass index (OR = 0.868, 95% CI: 0.788–0.957, P = 0.004), and inorganic phosphorus levels (OR = 0.513, 95% CI: 0.270–0.975, P = 0.042) independently influenced the likelihood of sarcopenia. Within the sarcopenic group, physical activity and BMI significantly correlated with the condition’s severity.ConclusionThe prevalence of probable or confirmed sarcopenia in patients on MHD is significant. Factors such as physical activity, body mass index, and inorganic phosphorus levels are independently associated the presence and severity of sarcopenia in this population.Trial registrationChinese Clinical Trial Registry (ChiCTR2100051111), registered on 2021–09–13.

A profile approach to physical activity levels: what’s intensity got to do with reasons and motives for exercise?

BackgroundDespite the well-known benefits of physical activity (PA), non-communicable disease and premature mortality rates among adults continue to rise. The relationship between adults’ goals and exercise-specific motivation on the type of PA intensity one engages remains unclear. The purpose of this study was to identify physical activity (PA) profiles based on frequency and intensity (i.e., levels of PA) in an adult sample. A secondary purpose was to examine how the PA profiles differ on the reasons people have for exercising and behavioral regulation.MethodsA Cross-sectional survey was conducted with 1,169 (46.8 ± 16.7 years) participants solicited from a hospital-affiliated wellness center, social media promotions, and a research volunteer registry. The International PA Questionnaire (IPAQ) was used to determine frequency, intensity, and time spent engaging in PA. Additionally, the Reasons to Exercise (REX-2) scale, the Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3), and demographics were assessed. K-cluster analyses were performed to identify profiles based on PA levels using the IPAQ guidelines. Multivariate analysis of variance (MANOVA) was used to assess profile differences.ResultsFive distinct PA clusters were derived, and defined as: a Low, Walking, Moderate Intensity, High Intensity, and Sitting cluster (p < .001). These clusters differed significantly (p < .001) from each other with respect to motivation, the reasons adults have for exercise, and PA levels.ConclusionThe results from this study support the important role of psychological factors such as motivation and reasons for exercise on behavioral outcomes (i.e., physical activity). For future research investigating adults PA- related behaviors, whether it be on adults starting a new exercise program or for PA maintenance, it may be beneficial to develop programs that encourage participants to reflect on the reasons they identify as important for exercising, and how such reasons contribute to their overall PA engagement behaviors.

Compliance of physical activity among adults with metabolic syndrome with the WHO recommendations

Abstract Introduction Low physical activity is a leading factor in 6% of deaths worldwide. In Bulgaria, it contributes to the deterioration of the health status of the population and determines 4.3% of the global burden of diseases. Over 70% of Bulgarian adults have insufficient physical activity during their free time. The aim of the study is to measure and assess the level of physical activity among adults with metabolic syndrome with the World Health Organization (WHO) Global recommendations. Methods A comparative study of the physical activity of a representative sample of 200 individuals with metabolic syndrome aged 54.7±10.5 from Pleven region was made with the WHO Global recommendations on physical activity for people living with chronic conditions. Modified Physical activity Questionnaire (PAQ) for adults was used for assessment of the physical activity. Data were processed with IBM SPSS v. 25. Results The weekly frequency of the vigorous-intensity physical activity (VIPA) was 1,61 days with a weekly duration of 215 minutes, which met the WHO recommendations on physical activity for people living with chronic conditions, but 64% of the respondents had none and only 26% had VIPA on 2 and more days a week. More than half of the respondents (55%) had none moderate-intensity aerobic PA. From the remaining, 34% had this type of PA on 3 and more days a week with duration of 225 minutes, which met the WHO recommendations. Walking more than 10 minutes a day on 5 and more days a week had 69% of the respondents (40 minutes/day). Only 12% had none walking. Only 2% stated that the physical inactivity is the most important cause for the rise of many non-communicable diseases. Conclusions More than half of the respondents had none vigorous- and moderate-intensity PA but the PA of the remaining met the WHO recommendations. Although physical inactivity is among the risk factors for the rise of many non-communicable diseases, contributing to death, it was not recognised by the respondents. Key messages • Walking is the most important physical activity for the adults with metabolic syndrome. • Increasing the duration of walking should be encouraged and supported to manage the metabolic syndrome.

High physical activity relates to higher risk of incident carotid plaque components

Abstract Background The rupture of carotid atherosclerotic plaque, primarily driven by plaque components, is among the leading causes of ischemic stroke. Although physical activity (PA) stands as a major modifiable target for prevention of atherosclerotic diseases, recent studies suggested a potential adverse impact of high-volume PA on atherosclerotic plaque burden in athletes. Data remains scarce from the community-dwelling population regarding to the impact of PA on the longitudinal change of carotid plaque components. Objectives To assess the association between PA and the incidence of carotid plaque components and explore whether the association of PA with stroke and all-cause mortality differs by the presence of plaque components. Methods Between 2007 and 2012, in a community- dwelling cohort in Netherlands, 1327 stroke-free persons (mean ± standard deviation age 72 ± 9 years, 45% women) with carotid atherosclerosis (carotid intima-media thickness &amp;gt; 2.5 mm) were invited for magnetic resonance imaging (MRI) to assess carotid plaque components. From these, 696 persons (1267 carotid arteries) underwent a follow-up MRI between 2014 and 2017 (median between-scan interval 6 years). Carotid plaque components included calcification, intraplaque hemorrhage (IPH), and lipid-rich necrotic core (LRNC). The volume of moderate, vigorous and total PA (unit: metabolic equivalent task hour, MET-h) was assessed using LASA Physical Activity Questionnaires around the time of the first MRI scan. Participants were followed for the occurrence of stroke or all-cause mortality until December 31, 2019. Generalized estimation equation and Cox regression models were used in the analyses, with adjustments for plaque size and other cardiovascular risk factors. Results Compared to lowest quintile PA group, participants in the highest quintile total PA group had a higher risk of new onset of plaque components, odds ratio (95%CI) 2.69 (1.21; 5.94) for calcification, 1.35 (0.82; 2.24) for LRNC and 1.93 (1.12; 3.34) for IPH (Figure 1). Similar associations were observed for vigorous PA but not for moderate PA. Over a median follow-up of 9.5 years, 118 persons suffered a stroke and 298 died. As shown in table 1, baseline IPH, rather than LRNC or calcification, modulated the associations of PA with stroke and all-cause mortality (P-interaction &amp;lt;0.05): higher total PA was associated with a lower risk of stroke among IPH-free persons, with the hazard ratio (95% CI) of 0.929 (0.867; 0.996) per 10 MET-h/week increase; no associations between PA and stroke were found among those with IPH. Similar associations were found between vigorous PA and all-cause mortality. Conclusions Among the middle-aged and elderly with subclinical atherosclerosis, high level PA, especially high vigorous PA, may lead to an unstable carotid plaque. The beneficial effect of PA on stroke and all-cause mortality is only among persons with a stable carotid plaque profile, especially without IPH.

Objective and subjective physical activity assessment in obese patients with eating disorders

Abstract Background Discrepancies between objective and subjective measures of physical activity have been reported in healthy populations but remain unexplored in adults with obesity and psychosomatic disorders. Exercise is key for reducing these disorders, yet physiological and psychosomatic factors may complicate valid activity assessments in this population. Here, we compare self-reporting with actigraph data in a clinical setting. Methods Over two years, 27 obese patients (21 female, 6 male; 43±14 yrs; 41.3±5.7 kg·m−2) with eating disorders (EDE-Q) were recruited from an Austrian Psychosomatic Center. Total physical activity was assessed using the metabolic equivalent (MET min/w) and sitting time (min/d). Objective data were collected using the SenseWear® wristband (SWA) during weeks 3-4 of patients’ clinical stay. SWA was worn for ≥18 h/d on ≥ 4 days, including one weekend day. Patients self-administered the International Physical Activity Questionnaire (IPAQ-SF) in alignment with the ∼7 days of SWA wear. Concurrent validity - SWA as a criterion - was assessed using regression analyses, and proportional bias was examined with regression and equality line similarity analyses. Results Comparison showed an overestimation of total activity (+45%; p&amp;lt;.001) and underestimation of sitting time (-28%; p&amp;lt;.001) with IPAQ-SF vs SWA. Within-patient correlations were poor for MET (r=.92, p&amp;lt;.001) and impractical for sitting time (r=.27, p=.018), with a proportional bias for both outcomes (p≤.001). Converting objective to subjective measures yielded typical errors of 232 (total activity) and 90 min (sitting time). Conclusions The observed disparities emphasize the need to integrate sensor-based assessment of physical activity into clinical practice or tailored public health initiatives for adult obesity and psychosomatic disorders. However, further research is needed to evaluate the long-term impact of incorporating accurate SWA data on intervention efficacy in this vulnerable group. Key messages • There was strong evidence for meaningful differences in objective vs subjective physical activity assessments in obese patients with eating disorders. • Integrating objective measures into treatment seems crucial to improve exercise-guided interventions and address the global obesity and psychosomatic disorders pandemic.

Built environmental characteristics, physical activity in neighbourhoods of Accra, Ghana

Abstract There is increasing evidence that characteristics of the built environment can influence residents’ lifestyles, physical activity thereby influencing the development of obesity and non-communicable diseases even in low- and middle-income countries. The aim of this study is to describe the characteristics of the built and the social environment of neighbourhoods of Accra, Ghana, and to explore association between neighbourhood characteristics and the physical activity of the residents. A cross-sectional study was conducted in Accra, 12 neighbourhoods were randomly selected based on high and low values of residential density and socioeconomic status. Sociodemographic, household and neighbourhood information were collected with an adapted questionnaire of NEWS (Neighbourhood Environment Walkability Scale) for Africa. Physical activity was assessed by WHO Global Physical Activity Questionnaire and social cohesion by the Perceived Neighbourhood Social Cohesion Questionnaire. Differences between variables by neighbourhood types were analysed using Chi square test and Kruskal Wallis test. Generalized linear model was performed to determine the association between neighbourhood characteristics and residents’ physical activity. The built environmental characteristics of different neighbourhood types and the physical activity of the residents showed significant differences. The associations indicated that individuals living in high residential density neighbourhoods had increased levels of engaging in physical activities. Land use mix, street connectivity, safety, aesthetics and social cohesion of neighbourhoods showed correlation with physical activity of residents. The built environment and social characteristics of neighbourhoods can influence the lifestyle and physical activity of residents in Accra, Ghana. Key messages • High residential density neighbourhoods correlated with higher level of physical activity. • Land use, street connectivity, safety and aesthetic of neighbourhoods and social cohesion showed correlation with physical activity.

Increasing step count of employees through the Semmelweis Workplace Health Promotion Program

Abstract Background Lifestyle greatly contributes to the development of age-related diseases. The goal of the Semmelweis University’s ‘Semmelweis Workplace Health Promotion Program’ is to develop interventions that facilitate healthy ageing. The aim of its first intervention was to increase the step count of participants by incorporating motivational elements offered through the university’s Center of Preventive Services. Methods A randomized controlled trial was conducted in spring 2024 with three study groups: those undergoing motivational interviews (MI, n = 49), those receiving motivational emails (ME, n = 51), and a control group (n = 53). Intervention groups (MI+ME) received weekly emails for 8 weeks emphasizing the benefits of increased step count and providing feedback on achievements. The MI group also took part in 4 biweekly consultations. Mean step counts of last week and energy expended while walking (MET) calculated from the International Physical Activity Questionnaire were recorded five and three times, respectively. Mixed model regressions were conducted for two pre-planned comparisons: MI+ME vs. controls, and MI vs. ME. Results Intervention groups exhibited a significant increase in average step count (1001 steps; 95% Confidence Interval [95% CI]: 349-1651) as a result of the program, while the control group experienced a non-significant decrease. This was accompanied by a significant increase in energy expenditure for walking (45 MET; 95% CI: 4-87) in intervention groups and a non-significant decrease for the control group. The study found no significant differences in step count and energy expenditure between the two intervention groups (MI vs. ME). Conclusions Our results suggest that workplace health promotion programs may effectively increase physical activity, and thus may be key in tackling the challenges posed by aging demographics. Preliminary findings did not indicate a superiority between email-based and motivational interview-based motivation. Key messages • Workplace health promotion is an essential tool in promoting healthy aging among the working-age population. • Step-count programs based on motivational interviewing serve as an effective and simple tool in increasing physical activity.

Association between fitness levels and physical activity in apparently healthy Colombian men

Abstract Physical condition (PC) such as strength and endurance favor functional independence and disease prevention (Melo, 2014). Objective: To characterize the levels of Physical Activity (PA) and CP in apparently healthy men who practice PA in different settings in Bogotá-Colombia. This study is observational cross-sectional, 485 Men (M) participated, mean age 42±17.8 years. To measure the levels PA the IPAQ (International Physical Activity Questionnaires) was applied. The Confidence Interval (CI) and Standard Error (SE) were taken into account. For PA levels, data were analyzed with Rstudio v2022.12.0, with empirical distribution tests, Kolmogorov-Smirnov normality and independence with Chi-Square (χ²), in addition, mean (X¯), percentage (%) and standard deviation (±). 90.6% of the H met the overall PA recommendations (Leisure Time+Active Transportation) with 95% CI (88.0-93.0) and SE (0.012). The PC variables such as; Body Mass Index (BMI), Body Adiposity Index (BAI), Abdominal Circumference (AC), Grip Strength (GS) and Maximal Oxygen Consumption (Vo2max). The results showed that 35.6% (26.9±1.48) of H were Overweight (Ow) and 10.6% (32.7±2.39) were Obese (Ob), 39.7% (98.4±6.8) with Cardiovascular Risk (Rcv) by AC and 24.3% (29.7±3.45) with risk by BAI. As for GS 41.5% (27.1±6.39) is weak and 32.3% (33.3±6.3) is low Vo2max. According to independence tests with χ² there is association between the G and BMI (χ²=1452.1, df = 1427, p-value=0. 315), G and AC (χ²=394.9, df = 382, p-value=0. 313), G and Vo2max (χ²=155.5, df = 6, p-value&amp;lt;2.2e-16), G and BAI (χ²=2970.3, df = 1502, p-value&amp;lt;2.2e-16), G and GS (χ²=6015.5, df = 1502, p-value&amp;lt;2.2e-16). This project was approved by the bioethics committee. Conclusions 149 men corresponding to 30.7% of the sample present an increased possibility of Rcv, despite compliance with global PA recommendations. It is recommended that PA programs reinforce the improvement and promotion of PC to prevent possible Rcv. Key messages • The capacities that define physical fitness (FC) such as strength and endurance favor functional independence and disease prevention (Melo, 2014). • Apparently healthy men in Colombia present a higher possibility of Cardiovascular Risk due to low levels of physical fitness, despite compliance with global BP recommendations.
