Association among physical activity, anxiety and oral health status in Chinese university students: A cross-sectional study

Background

Evidence is limited regarding the relationship among physical activity, anxiety, and oral health in Chinese university students. This cross-sectional investigation aimed to assess the potential relationship between physical activity, anxiety, and oral health conditions among university students in China.

Methods

An online questionnaire measuring physical activity, anxiety status, and oral health condition was completed by 1604 university students. The International Physical Activity Questionnaire Short Form (IPAQ-SF) and Generalized Anxiety Disorder-7 (GAD-7) were selected to evaluate physical activity and anxiety, respectively. Oral health condition was assessed through several self-reported variables, including self-reported toothache, gingival bleeding, frequency of tooth brushing, and use of dental floss. Multivariate logistic regression was performed to analyze the underlying relationship between outcome variables. The control variables included age, height, weight, gender, whether only one-child, education level, parental education level, smoking status, drinking habits, and length of sleep. Path analysis was conducted to disentangle the association between physical activity, anxiety, and oral health conditions.

Results

Among 1604 university students, 666 (41.5 %) were males and 938 (58.5 %) were females, with an average of 21.9 ± 2.8 years. Only 833 (51.9 %) reported sufficient physical activity, while 684 (42.6 %) of the subjects displayed varying degrees of anxiety. Self-reported gingival bleeding was associated with insufficient physical activity (OR = 1.25; 95%CI: 1.02-1.55), anxiety (OR = 0.45; 95%CI: 0.27-0.74), frequency of tooth brushing (OR = 0.75; 95%CI: 0.60-0.95) and use of dental floss (OR = 0.75; 95%CI: 0.59-0.96), while toothache was not directly influenced by the physical activity and anxiety among university students. Anxiety markedly mediated the relationship between physical activity and oral health conditions.

Conclusions

Anxiety was considered a factor associated with the level of physical activity, tooth brushing habits, and self-reported gingival bleeding among university students. Further investigations are required to elucidate whether oral health conditions could be enhanced through the improvement of anxiety and physical activity.

Exploring Factors Associated with Physical Activity in the Elderly: A Cross-Sectional Study during the COVID-19 Pandemic

The COVID-19 pandemic negatively influenced individuals' physical activity levels (PALs) and particularly the PAL of the elderly. However, few studies have examined the correlates of PALs in this population during the pandemic. This study aimed to evaluate the residence-specific correlates of PALs in elderly people from Croatia and Bosnia and Herzegovina during the COVID-19 pandemic. The participants were 211 persons older than 65 years (101 females), of whom 111 were community-dwelling residents, and 110 were nursing home residents (71.11 ± 3.11 and 72.22 ± 4.01 years of age, respectively; t-test = 0.91, p < 0.05). The variables included health status, residential status sociodemographic factors, anthropometrics (body mass, height, and body mass index), and PAL. PAL was evaluated using a translated version of the Physical Activity Scale for the Elderly (PASE), and was validated in this study. PASE showed good test-retest reliability (51% of the common variance) and validity (57% of the common variance, with the step count measured using pedometers). Apart from participants' health status and age, PAL was positively correlated with (i) community-dwelling residence (OR = 1.93, 95% CI: 1.60-2.23), and (ii) a lower BMI (OR = 0.85, 95% CI = 0.71-0.98). The pre-pandemic physical activity was positively correlated with the PAL of the nursing home residents (OR = 1.2, 95% CI: 1.02-1.45). A higher education level was positively correlated with the PAL of community-dwelling residents (OR = 1.31, 95% CI: 1.04-1.66). This study evidenced the residence-specific correlates of PALs, and enabled the identification of specific groups that are at risk of having low PALs during the pandemic. Future studies examining this problem during a non-pandemic period are warranted.

Healthism online: 'What I eat in a day' vlogs before and during COVID-19 restrictions

Objective and setting

The COVID-19 pandemic and its restrictions coincide with an increase in body weight and changes in health-related habits worldwide. This study focusses on the way health-related habits are portrayed online in digital food cultures. The study aims to investigate if and how the content of high-profile Dutch 'What I eat in a day' vlogs has changed during the first period of COVID-19 restrictions. We approach changes in digital food culture through the concept of 'healthism' and see vloggers as cultural intermediaries.

Design and participants

We collected the most watched vlogs of almost all high-profile Dutch influencers pre-post corona and analyzed these in a mixed method approach by using summative and thematic content analysis.

Results

Pre-COVID vlogs highlight an explicit consciousness of energy balance-related behavior, focusing on calorie counting, avoidance of unhealthy food and the use of tracking apps. In vlogs uploaded in 2020, these themes are less present. Instead, intuitive eating and listening to one's body are more central themes within the vlogs.

Conclusions

We consider the shift towards intuitive eating as another variant of "wellness diets" rather than a shift away from dieting, furthered by COVID-19 restrictions. The core values of health and self-regulation are upheld within the shift towards intuitive eating. Yet, we nuance the broad claims of healthism in biopolitics and point to relevant cultural changes within foodscapes.

Influence of Regular Physical Activity on Sleep

Good sleep and adequate physical activity are essential to health. Yet, large numbers of people are chronically deficient in sleep and physical activity. About 1 in 3 Americans get less than 7 h of sleep per night and only 1 of 4 adults regularly complete weekly physical activity in amounts recommended for good health. This chapter reviews research that has examined relationships between regular physical activity and sleep. The overall weight of evidence supports that regular physical activity is associated with better sleep quality among healthy adults, with epidemiological studies showing moderate-sized effects and more well-controlled randomized controlled trial experiments often showing larger effects. Large epidemiology studies suggest that the relationship between regular physical activity and better sleep quality may partially mediate the well-established associations between physical activity and reduced risk of mortality, cardiovascular diseases, and dementia. There is evidence that the completion of regular physical activity also is associated with better sleep quality among those with certain sleep disorders (i.e., insomnia, obstructive sleep apnea, and restless legs syndrome), mental health disorders (i.e., depression and posttraumatic stress disorder), and medical illnesses (i.e., breast cancer survivors). The evidence is inadequate to support that regular physical activity substantially improves sleep quality either (i) in children, adolescents, and older adults, (ii) in those with cancers except for breast cancer, (iii) in those with fibromyalgia, or (iv) among those with chronic kidney disease. Also, there is inadequate evidence to conclude that sleep quality is disrupted during weeks when competitive athletes engage in periods of overtraining.

Social Distancing in the COVID-19 Pandemic: Associated Factors, Health Outcomes, and Implications

Social distancing has reemerged as a public health measure for containing the spread of COVID-19. This integrative review aims to analyze the historical use of social distancing, the current application during COVID-19, individual factors that affect social distancing practices, and consequential health outcomes. We analyzed relevant literature from searches conducted on Scopus, PubMed, and PsycINFO. We found that resources, culture, age, gender, and personality are associated with the degree to which people practice social distancing. Furthermore, social distancing changes our lifestyles and behavior and results in multifaceted health outcomes, including decreased physical activity and sunlight exposure, increased weight gain, and impaired sleep quality. On the positive side, social distancing has been linked to reduced crime rates and environmental damage, as well as better social and family ties. Future interventions may be utilized to increase adherence to social distancing practices and to mitigate the negative health effects of social distancing.

Importance of training volume through the use of step trackers apps promoted from the subject of physical education to change body composition, physical fitness and physical activity in adolescents and the influence of gender✰,✰✰

The aim of the present study was to determine the changes in physical activity level (PA), kinanthropometric and derived variables, and physical fitness in adolescents, as a result of an out-of-school intervention with mobile step tracker apps promoted from the field of physical education, according to the volume of training completed and gender. A randomized controlled trial was carried out with 400 adolescents (210 males and 190 females) aged 12 to 16 years old (mean age: 13.96 ± 1.21 years-old). Adolescents were divided into experimental group (EG) (n = 240) and control group (CG) (n = 160). Two measurements were carried out, separated by a 10-week intervention, and PA, kinanthropometric variables and physical condition were measured. During the intervention, EG must use Strava (n = 74); Pokémon Go (n = 59); Pacer (n = 60); and MapMyWalk (n = 47) a minimum of 3 times per week, covering an incremental distance from 7,000 steps per day (week 1) to 12,500 steps per day (week 10). After that, EG were divided in quartile according to the volume of training completed. The results obtained showed a significant increase between pre-and post in PA (p = 0.009-0.044) and curl-up (p < 0.001-0.040) in EG regardless the quartile of compliance, and a reduction in fat variables (p < 0.001) and an increase in CMJ in 75-100 % compliance group (p = 0.005). The introduction of the covariate gender did not introduce changes in the intra-group evolution. On inter-group differences, differences were only found for the post-test values between 0-25 % Vs 25-50 % and between 50-75 % Vs 75-100 % with the group that completed a longer distance being the one that showed the lowest values in the post-test in both cases. When including the covariate gender, no significant differences were found for either the pre-test or the post-test on either variable. To conclude, a higher training volume with mobile apps seems to be relevant in the increase PA and strength and decrease of fat mass. The gender factor is not influential in the intra-group changes, but it is influential in the inter-group differences.

Physical activity coaching in patients with interstitial lung diseases: A randomized controlled trial

OBJECTIVES

Physical activity is reduced in patients with interstitial lung disease (ILD) and physical inactivity is related to poor health outcomes. We investigated the effect of a telecoaching intervention to improve physical activity in patients with ILD.

METHODS

Eighty patients with ILD were randomized into the intervention or control group. Patients in the intervention group received a 12-week telecoaching program including a step counter, a patient-tailored smartphone application, and coaching calls. Patients in the control group received usual care. Physical activity (primary outcome), physical fitness and quality of life were measured at baseline and 12 weeks later with an accelerometer, 6-min walking test and quadriceps muscle force and the King's Brief Interstitial Lung Disease questionnaire (K-BILD).

RESULTS

Participation in telecoaching did not improve physical activity: between-group differences for step count: 386 ± 590 steps/day, p = .52; sedentary time: 4 ± 18 min/day, p = .81; movement intensity: 0.04 ± 0.05 m/s2, p = .45). Between-group differences for the 6-min walking test, quadriceps muscle force and K-BILD were 14 ± 10 m, p = .16; 2 ± 3% predicted, p = .61; 0.8 ± 1.7 points, p = .62 respectively.

CONCLUSIONS

Twelve weeks of telecoaching did not improve physical activity, physical fitness or quality of life in patients with ILD. Future physical or behavioural interventions are needed for these patients to improve physical activity.

Global pain levels before and during the COVID-19 pandemic

Physical pain has trended upward globally over the last decade. Here, we explore whether the COVID-19 pandemic modified this alarming trend. We used data from 146 countries worldwide (510,247 respondents) to examine whether pain levels changed during the COVID-19 pandemic. Adjusted regressions across countries revealed that 33.3% of people were in pain in 2019, 32.8% in 2020, 32.5% in 2021, and 34.1% in 2022. The change in pain from 2019 to each of the pandemic years was not statistically significant. This suggests that, on average, there was no significant change in pain during the pandemic. However, from 2019 to 2020 there was a significant decline in pain among individuals over 55 years of age, those who were widowed, and those without children in the household. On a global scale, the COVID-19 pandemic was not associated with a significant change in pain levels. The concerning pre-pandemic elevation in global pain continued during this challenging period.

Re-assessing the social climate of physical (in)activity in Canada

Social-ecological models suggest that a strategy for increasing population physical activity participation is to reconstruct the "social climate" through changing social norms and beliefs about physical activity (PA). In this study, we assessed whether the PA social climate in Canada has changed over a five-year period after controlling for sociodemographic factors and PA levels. Replicating a survey administered in 2018, a sample of adults in Canada (n = 2,507) completed an online survey assessing social climate dimensions, including but not limited to descriptive and injunctive norms. Descriptive statistics were calculated, and binary logistic regressions were conducted to assess the associations of sociodemographic factors and year of the survey with social climate dimensions. Results suggest some social climate constructs are trending in a positive direction between 2018 and 2023. Physical inactivity was considered a serious public health concern by 49% of respondents, second to unhealthy diets (52%). Compared to those who participated in the 2018 survey, participants in 2023 were less likely to see others walking or wheeling in their neighbourhood (OR = 1.58, 95% CI: 1.41, 1.78), but more likely to see people exercising (OR = 0.82, 95% CI: 0.73, 0.92) and kids playing in their neighbourhood (OR = 0.75, 95% CI: 0.66, 0.85). No changes were reported between 2018 and 2023 in individuals' perceptions of whether physical inactivity is due to individual versus external factors (OR = 0.99, 95% CI: 0.87, 1.13). The findings of this work indicate a modest positive shift in some measured components of the social climate surrounding PA although attributing causes for these changes remain speculative.

Anonymizing at-home fitness: enhancing privacy and motivation with virtual reality and try-on

Introduction

This study aimed to address privacy concerns associated with video conferencing tools used in home-based exercise training. To that end, a method that could anonymize participants' appearances and exercise environments during at-home fitness sessions was proposed.

Methods

This method combines virtual reality for 3-D human-model rendering using key-points tracking with a virtual try-on system enhanced by UV mapping and instance segmentation. To validate the proposed method, we conducted a user study by recruiting participants to assess effectiveness of virtual reality and virtual try-on in terms of privacy protection, self-confidence, and coaching satisfaction.

Results

Experimental results demonstrated the effectiveness and improved user experience of using virtual reality or virtual try-on in remote fitness, particularly in enhancing privacy protection and self-confidence with statistical significance. However, no significant differences were noted in coaching satisfaction.

Discussion

These findings confirmed the efficacy of our proposed approach. We believe that the proposed approach can significantly contribute to the future of remote fitness training, offering a more secure and engaging environment for users, thereby potentially increasing adherence to fitness regimens and overall physical wellbeing.

Impact of the COVID-19 Pandemic on Physical Activity among Mostly Older, Overweight Black Women Living in the Rural Alabama Black Belt

Despite well-documented global declines in physical activity (PA) during the COVID-19 pandemic, little is known regarding the specific impact among underserved, rural Alabama counties. This is concerning as this region was already disproportionately burdened by inactivity and related chronic diseases and was among the hardest hit by COVID-19. Thus, the current study examined the effect of COVID-19 on PA in four rural Alabama counties. An ancillary survey was administered between March 2020 and August 2021 to the first cohort (N = 171) of participants enrolled in a larger PA trial. Main outcomes of this survey included the perceived impact of COVID-19 on PA, leisure-time PA, and social cognitive theory (SCT) constructs at 3 months. Almost half of the participants reported being less active during the pandemic (49.7%) and endorsed that COVID-19 made PA more difficult (47.4%), citing concerns such as getting sick from exercising outside of the home (70.4%) and discomfort wearing a face mask while exercising (58%). Perceived COVID-19 impact on PA was significantly associated with education, household dependents, and gender (p's < 0.05). More women, parents, and college graduates reported that the COVID-19 pandemic made PA more difficult. Overall, there were no significant associations between PA, SCT constructs, or perceived COVID-19 impact on PA scores at 3 months. While the pandemic made PA difficult for many participants, these barriers were not associated with leisure-time PA levels or related theoretical mechanisms of action, which bodes well for the success of our ongoing intervention efforts and the resiliency of these communities.

Prevalence and factors associated with long COVID in adults from Southern Brazil: findings from the PAMPA cohort

Most COVID-19 survivors have reported experiencing persistent symptoms after the infection - these types of cases are known as long COVID. Since Brazil was an epicenter of the COVID-19 pandemic, a high burden of long COVID is expected. This study aimed to identify the prevalence and factors associated with long COVID in adults in Southern Brazil, analyzing data from the PAMPA cohort. Participants filled out a self-reported online questionnaire in June 2022. This study only included subjects who tested positive for COVID-19. Long COVID was defined by any symptoms that persisted for at least three months after the SARS-CoV-2 infection. Poisson's regression models with robust variance were used to identify factors associated with long COVID; and results were reported as prevalence ratios (PR) and respective 95% confidence intervals (95%CI). A total of 1,001 participants (77.4% women, mean age [SD] = 38.3 [11.9] years) were analyzed. The prevalence of long COVID among these patients was 77.4% (95%CI: 74.7; 79.9). The likelihood of long COVID was higher in unvaccinated participants (PR = 1.23, 95%CI: 1.06; 1.42), in those with chronic conditions (PR = 1.13, 95%CI: 1.04; 1.24), and in those who were hospitalized due to the COVID-19 infection (PR = 1.24, 95%CI: 1.16; 1.32). This prevalence was also higher in women (PR = 1.21, 95%CI: 1.09; 1.33) than in men. Physical activity was associated with a reduced likelihood of fatigue, neurological complications, coughing, and headaches as persistent symptoms after a COVID-19 infection. It was found that three out of four adults in Southern Brazil experienced long COVID. Public policies aiming to reduce the burden of long COVID must be prioritized, especially in groups that are at higher risk of developing this harmful condition.

SMART System in the Assessment of Exercise Tolerance in Adults

Health-oriented physical activity should meet two key criteria: safety and an optimal level of exercise. The system of monitoring and rationalization of training (SMART) was designed to meet them. SMART integrates a custom-configured inertial measurement unit (IMU) and a sensor with real-time heart rate measurement (HR) using a proprietary computer application. SMART was used to evaluate the safety and exercise load with 115 study participants: 51 women (44.35%) and 64 men (55.65%) aged 19 to 65 years. The exercise test was the 6MWT test. In 35% of the participants, the mean HR exceeded the recognized safe limit of HR 75% max. Ongoing monitoring of HR allows for optimal exercise and its safety. Step count data were collected from the SMART system. The average step length was calculated by dividing the distance by the number of steps. The aim of the present study was to assess the risk of excessive cardiovascular stress during the 6MWT test using the SMART system.

Physical activity and life satisfaction among adolescents before and during the COVID-19 pandemic

The negative impact of the COVID-19 pandemic and distance education has significantly affected adolescents' lives. The restrictive policies negatively affected their physical and mental health and life satisfaction. It is therefore desirable to look for ways to eliminate similar negative impacts on adolescents in the future. This study aimed to identify the differences in the association between physical activity and life satisfaction in Polish adolescents before and during the pandemic. The study included 1541 participants (891 before the pandemic and 650 during the pandemic) aged 15-19 years. The International Physical Activity Questionnaire-Long Form questionnaire was used to assess physical activity, and the Bern Subjective Well-Being Questionnaire was used to evaluate life satisfaction. The objectivity of data collection and analysis before and during the pandemic was ensured by the web application the International Database for Research and Educational Support. During the pandemic, we found lower physical activity and life satisfaction in both boys and girls compared to before the pandemic. Girls with low and high physical activity levels showed significantly lower life satisfaction during the pandemic than they did before. Low life satisfaction was associated with lower physical activity, and high life satisfaction was associated with greater total physical activity. Both boys and girls with low and high life satisfaction achieved significantly fewer physical activity recommendations during the pandemic. High life satisfaction increased the likelihood of meeting the recommendations for physical activity before and during the pandemic. This study provides new insights into the differences and associations between life satisfaction and physical activity in adolescent boys and girls before and during the pandemic. It provides suggestions for the prevention of possible future restrictions in the school settings. Support for post-pandemic life satisfaction in adolescents should focus mainly on increasing vigorous physical activity and improving adolescent participation in organized physical activity settings.

Age group differences in psychological distress and leisure-time exercise/socioeconomic status during the COVID-19 pandemic: a cross-sectional analysis during 2020 to 2021 of a cohort study in Japan

Objective

This study aimed to determine the association between psychological distress and leisure-time exercise/socioeconomic status by age group, using data from a cohort study in Japan during the COVID-19 pandemic.

Methods

This cross-sectional study was conducted among participants in the ME-BYO cohort, aged 20-85 years, living or working in Kanagawa, Japan. A questionnaire was disseminated to 1,573 participants (51.7% men) between December 2020 and March 2021. The questionnaire items included psychological distress (using the 6-item Kessler Psychological Distress Scale [K6]), leisure-time exercise, and socioeconomic status. Multivariate analyses were conducted using logistic regression analysis for each age group.

Results

We found that 47.4% of 20-39-year-olds, 40.6% of 40-64-year-olds, and 28.3% of 65-85-year-olds experienced psychological distress (K6: ≥5 points). For those aged 20-39 years, leisure-time exercise (odds ratio [OR] (95% confidence interval) = 0.45 (0.28-0.73)) and higher annual household income [0.53 (0.32-0.90)] were associated with less psychological distress. For those aged 40-64 years, older age was associated with less psychological distress, while full-time work [1.98 (1.05-9.71)] was associated with more psychological distress. In the 65-85-year age group, higher education and higher annual income tended to be associated with less psychological distress. For those over 40 years of age, living with other(s) was associated with reduced psychological distress.

Conclusion

In the general population of Japan, not engaging in leisure-time exercise and low income affect psychological distress among young adults. Further detailed studies are needed to consider overall physical activity, job type, and work style.

Influence of the COVID-19 Pandemic on Musculoskeletal Complaints and Psychological Well-Being of Employees in Public Services-A Cohort Study

BACKGROUND

The COVID-19 pandemic resulted in unprecedented restrictions on public and private life. The aim of the study was to investigate the impact of the COVID-19 pandemic on the physical and mental health of employees in the public sector, especially patient-related professions.

METHODS

For the data collection in summer 2021, an online questionnaire was used. Compared to a pre-pandemic point of time, the prevalence, frequency, and intensity of musculoskeletal pain, mental well-being, health status, and quality of life were recorded.

RESULTS

The questionnaire was completed by 1678 employees (f: 1045, m: 617). A total of 1504 employees (89.6%) were affected by complaints. Compared to before the pandemic, the prevalence and intensity of musculoskeletal complaints and psychological distress increased significantly. Patient-related professions (n = 204) showed significantly higher levels of stress and discomfort in several aspects (p < 0.05).

CONCLUSIONS

Due to the COVID-19 pandemic, there was an increase in musculoskeletal complaints and a decrease in psychological well-being. Preventive factors related to mental health were identified as male gender, a middle- to older-age group, employees with children, and working from home. Attention should be drawn to these findings and prevention strategies should be brought into focus to strengthen the employees' health. Special focus should be drawn to patient-related professions who are particularly confronted with pandemic-associated challenges.

Changes in Teleworking and Physical Activity Behaviors in the United States Before and After Emergence of COVID-19

OBJECTIVE

The aim of the study is to determine the prevalence of perceived decreases in three physical activity (PA) behaviors and meeting the PA guideline, by changes in telework.

METHODS

US workers ( N = 2393) reported teleworking and PA behaviors before and after COVID-19 emergence. Those reporting more and less telework were compared with those reporting stable telework on prevalence of (1) decreasing behaviors and (2) meeting the aerobic guideline (≥150 min/wk of moderate-intensity PA).

RESULTS

Compared with workers with stable telework, those with increased telework were more likely to report decreases in any PA (by 61%), active transportation (65%), and park use (52%). Workers who deceased telework were also more likely to report decreases in these behaviors. Groups were equally likely to meet the guideline.

CONCLUSIONS

Changes in teleworking status-either more or less-may be associated with decreased participation in PA behaviors.

Global trends and future prospects of COVID-19 and physical activity: Bibliometric analysis

BACKGROUND

Containment measures implemented during the COVID-19 pandemic have led to drastic changes in daily life and effects on health behaviors such as decrease in physical activity (PA) levels. This study aims to present a general framework to researchers on COVID-19 and PA research in relation with changes in studies within years, current trend topics, gaps in the research field and possible future trends.

METHODS

A total of 1819 articles indexed in the WoS core collection database were analyzed according to publication year, citation, country and institution collaborations, coword, co-citation networks, concept-topic trends and topic clusters using bibliometric analysis.

RESULTS

The most productive country was the USA(n = 335), and the most productive institution was University of London in UK (n = 38). The most cited publication was the study by Ammar et al, (2020) (n = 188). In 2020, the most popular topics were PA and health meanwhile in 2021 behavior, lifestyle, social media and in 2022 habits, long COVID, sleep quality topics were in the foreground. Studies in 2023 focus on how COVID-19 affects PA habits and the associations between COVID-19-based anxiety and sleep patterns. These studies focused especially on effects of sport participation on life quality, diet, depression, mental health on young athletes, children, adolescent persons, older adult groups.

CONCLUSIONS

An important gap in the study area is research on effect of changing lifestyle due to pandemic on individuals and the society during the Post COVID-19 period. If benefits of PA will not be limited to only physical benefits and psychological emotional, cognitive and social benefits are also taken into consideration, it is important that researchers conduct long-term and widescale observations.

Impact of COVID-19 Pandemic on Children's Fundamental Motor Skills: A Study for the Taiwanese Preschoolers Teachers

The outbreak of the COVID-19 pandemic has resulted in reduced opportunities for children to engage in fundamental motor skills [FMS]. This prolonged inactivity and restriction of play can have serious consequences for children's physical and mental health. The purpose of this study was to explore teaching strategies during the pandemic, whether there were differences in children's motor development, and the differences in the implementation of physical movement courses before and during the pandemic from the perspective of preschool teachers. This study was a retrospective study using an internet survey, and participants comprised 2337 preschool teachers. The statistical methodology of this study included descriptive statistics, the dependent t-test, and the independent t-test. The results showed that regardless of the time, frequency, activity intensity, and frequency of outdoor courses, the results from before the pandemic was better than those taken during the pandemic. Only the "frequency of implementing physical movement courses indoors every week" had not been affected by the pandemic. This study also obtained the performance of "children's fitness", "overall performance of physical movement ability", "stability movement skills", "locomotor movement skills", and "manipulative movement skills". All were better before the pandemic than during the pandemic. During the COVID-19 pandemic, mixed-age classes performed better than same-age classes in terms of frequency, time, intensity, outdoor course implementation, and physical fitness. Public schools performed better than private schools in terms of frequency, time, intensity, outdoor course implementation, and fundamental motor skills performance. Private schools implemented physical movement courses indoors every week, which was more than public schools. Excepting the frequency of implementing physical movement courses indoors every week, fewer than schools with five classes performed better than those who had more than schools with six classes. Finally, rural schools were better than urban schools in the implementation of outdoor courses and fundamental motor skills performance. Therefore, we suggest that in response to the pandemic, teachers should further improve their professionalism and use diversified teaching methods, and guide students to be willing to learn and improve their skill performance.

Leisure time physical activity and exercise performance in active older people in rural areas-Comparison of the first and second COVID-19 related lockdown in Germany

The closure of all sports facilities during the two lockdowns in Germany favoured a reduction of leisure time physical activity during the COVID-19 pandemic. The aim of this study was to compare leisure time physical activity during the 1st and 2nd lockdown and to examine exercise performance before and after resumption of exercise. Leisure time physical activity was measured by the Longitudinal Urban Cohort Ageing Study (LUCAS) functional ability index and energy expenditure in the Minnesota Leisure Time Physical Activity Questionnaire. Participants' exercise performance was extracted from a chip-controlled fitness circuit. Differences were tested for statistical significance using Friedman tests. 35 participants above 60 years were included from the Oldenburg area (20 women, 15 men, mean age and standard deviation 71±6 years). The decline in energy expenditure was higher during the 2nd lockdown (1st lockdown: Median -55.7 kcal.day-1, Q0.25-121.3 kcal.day-1, Q0.75 132.9 kcal.day-1; 2nd lockdown: Median -119.7 kcal.day-1, Q0.25-255.6 kcal.day-1, Q0.75-65.1 kcal.day-1; Friedman test: p<0.001, n = 35, W = 0.262). The time spent in the fitness circuit decreased from lockdown to lockdown as well as the number of participants exercising there. Intense activities were performed during the two lockdowns by only 7 and 3 participants, respectively, and were not resumed by two-thirds of the participants after the 2nd lockdown. During the 1st lockdown, exercise performance on resistance exercise devices increased in most of them, while it decreased by 1 to 7% during the 2nd lockdown. The lockdowns limited leisure time physical activity in older adults. This was more pronounced during the lockdown in winter 2020/2021, when participants engaged less in outdoor activities. Therefore, measures should be taken to maintain physical activity and muscle strength, especially during winter months, with a home-based training, if visiting gyms is not possible.

Nutrition-Related Experiences of Women With Perinatal Depression During the COVID-19 Pandemic: A Qualitative Study

Women with perinatal depression are at a high risk for unhealthy dietary behaviors but whether the coronavirus disease 2019 (COVID-19) pandemic has exacerbated this risk is unknown. Here we report the findings of a qualitative study exploring the impact of the COVID-19 pandemic on nutrition-related experiences of women with perinatal depression. Using a qualitative descriptive approach, in-depth interviews were conducted with 18 women with a history of perinatal depression and 10 healthcare providers. A semistructured format elicited how food and nutrition-related behaviors of women with perinatal depression were affected by the COVID-19 pandemic. Thematic analysis identified 4 themes related to the COVID-19 pandemic: (1) Adaptations in shopping and cooking behaviors; (2) increases in stress and declines in respite; (3) declines in support and increases in isolation; and (4) low levels of breastfeeding guidance. Our findings confirm the importance of resilience among women with perinatal depression and future research is needed to elucidate the mechanisms connecting resilience and dietary behaviors.

The COVID-19 Pandemic and Coronary Heart Disease: the Next Surge

PURPOSE OF REVIEW

In this narrative review, we highlight different ways in which the COVID-19 pandemic has impacted coronary heart disease (CHD) burden and how a surge in morbidity and mortality may be expected in the near future. We also discuss potential solutions, and the direction subsequent research and corrective actions should take.

RECENT FINDINGS

COVID-19 has been implicated in the development and worsening of CHD via acute and chronic mechanisms in the form of plaque rupture, destabilization, and sustenance of a chronic inflammatory state leading to long COVID syndrome and increased rates of myocardial infarction. However, indirectly the pandemic is likely to further escalate the CHD burden through poor health behaviors such as tobacco consumption, reduced physical activity, economic devastation and its associated sequelae, and regular cardiac care interruptions and delays. COVID-19 has increased the total CHD burden and will require extensive resource allocation and multifaceted strategies to curb future rise.

Characteristics and correlates of disease-related knowledge and exercise self-efficacy among cardiac patients attending virtual cardiac rehabilitation during the first COVID-19 lockdown in Peru

BACKGROUND

Government responses and restrictions due to the COVID-19 pandemic (e.g., limits to non-urgent health care services, including non-urgent outpatient appointments) led to the suspension of center-based (in-person) cardiac rehabilitation (CR), with many programs switching to virtual delivery. This study aimed to understand the characteristics and correlates of disease-related knowledge and exercise self-efficacy in a group of patients attending a virtual CR program during the first COVID-19 lockdown in Peru.

METHODS

In this prospective observational study, 240 patients receiving virtual CR care (exercise instructions and patient education) between August/2020 and December/2021 completed questionnaires pre- and post-CR assessing disease-related knowledge (CADE-Q SV questionnaire) and self-efficacy (SE; Bandura's Exercise SE scale). Paired t tests were used to investigate changes pre/post-CR and Pearson correlation coefficients were used to determine the association between knowledge/SE and patients' characteristics.

RESULTS

Participants were mainly comprised of men, with a cardiac diagnosis of stable coronary artery disease, who underwent percutaneous coronary intervention or had a known diagnosis of hypertension and with at least one cardiovascular risk factor (95.8%). Mean total knowledge scores improved significantly at post-CR (12.9 ± 2.4 to 15.6 ± 2.0/20; p<0.001), as well as in 4/5 knowledge areas (cardiovascular risk factors, exercise, nutrition, and psychosocial risk; p<0.001). Mean SE scores improved significantly at post-CR (1.9 ± 0.9 to 3.0 ± 0.9/5; p = 0.01). Post-CR knowledge and SE were significantly correlated with cardiac diagnosis and surgical procedures (r = 0.17, p = 0.02 and r = 0.27, p = 0.02, respectively).

CONCLUSIONS

The virtual CR program improved disease-related knowledge and SE of cardiac patients during the first months of the COVID-19 pandemic. Post-CR outcomes were correlated with cardiac diagnosis and surgical procedures and more research with other characteristics is warrantied.

Physical activity, sleep, and mental health during the COVID-19 pandemic: A one-year longitudinal study of Spanish university students

The objective of this longitudinal study was to analyze changes in physical activity, sedentary time, sleep, anxiety, mood, and perceived health as a result of COVID-19 pandemic in a cohort of Spanish university students, both during the home confinement and one year after. Additionally, we analyzed the associations between physical activity, sedentary time, and other measured parameters. Data were collected through two online questionnaires that included the International Physical Activity Questionnaire-Short Form, the Pittsburgh Sleep Quality Index, and self-reported anxiety, mood, and perceived health levels before, during and one year after home confinement. Participants reported decreased physical activity, increased sedentary time, and deterioration in sleep quality and perceived health during confinement. Most parameters had improved one year later; however, the participants still reported less physical activity, more sedentary time, and deterioration in sleep quality and perceived health compared to before confinement. Men reported greater reduction of physical activity during home confinement than women. In contrast, women reported reduced physical activity one year after confinement, whereas men reported increased activity. Participants reported higher anxiety and worse mood both during and one year post-confinement compared to pre-confinement, with women reporting higher levels of anxiety than men. Sports science students were closer to regaining pre-pandemic levels of physical activity one year post-confinement than students in other disciplines. Sleep, anxiety, and mood were worse among students with obesity compared to students in other BMI categories. Overall, increased physical activity and decreased sedentary time were associated with less anxiety and better sleep, mood, and perceived health during and one year post-confinement. In conclusion, our results demonstrate that physical activity, sedentary behavior, sleep, anxiety, mood, and perceived health were disrupted one year after home confinement. Higher levels of physical activity and lower sedentary time were associated with preserved sleep and mental health during the pandemic.

Four-Year Increase in Step Cadence Is Associated with Improved Cardiometabolic Health in People with a History of Prediabetes

PURPOSE

To investigate associations between 4-yr change in step cadence and markers of cardiometabolic health in people with a history of prediabetes and to explore whether these associations are modified by demographic factors.

METHODS

In this prospective cohort study, adults, with a history of prediabetes, were assessed for markers of cardiometabolic health (body mass index, waist circumference, high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], triglycerides, and glycated hemoglobin A1c [HbA1c]), and free-living stepping activity (activPAL3™) at baseline, 1 yr, and 4 yr. Brisk steps per day were defined as the number of steps accumulated at ≥100 steps per minute and slow steps per day as those accumulated at <100 steps per minute; the mean peak stepping cadence during the most active 10 minutes of the day was also derived. Generalized estimating equations examined associations between 4-yr change in step cadence and change in cardiometabolic risk factors, with interactions by sex and ethnicity.

RESULTS

Seven hundred ninety-four participants were included (age, 59.8 ± 8.9 yr; 48.7% women; 27.1% ethnic minority; total steps per day, 8445 ± 3364; brisk steps per day, 4794 ± 2865; peak 10-min step cadence, 128 ± 10 steps per minute). Beneficial associations were observed between change in brisk steps per day and change in body mass index, waist circumference, HDL-C, and HbA1c. Similar associations were found between peak 10-min step cadence and HDL-C and waist circumference. Interactions by ethnicity revealed change in brisk steps per day and change in peak 10-min step cadence had a stronger association with HbA1c in White Europeans, whereas associations between change in 10-min peak step cadence with measures of adiposity were stronger in South Asians.

CONCLUSIONS

Change in the number of daily steps accumulated at a brisk pace was associated with beneficial change in adiposity, HDL-C, and HbA1c; however, potential benefits may be dependent on ethnicity for outcomes related to HbA1c and adiposity.

Analysing features of home-based workout during COVID-19 pandemic: a systematic review

OBJECTIVE

Since the beginning of the COVID-19 pandemic, a decrease in physical activity (PA) related to home confinement has been reported worldwide. However, some individuals were able to engage in physical activities at home. Thus, in a perspective of public health, it may be useful to analyse the available evidence regarding PA adopted during home restrictions, in order to identify possible strategies to help people stay active even during emergency situations. The aim of this review was to analyse how healthy individuals spontaneously exercised at home in the course of the pandemic, in order to detect possible factors associated with this behaviour.

STUDY DESIGN

A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

METHODS

The protocol was registered in PROSPERO, an international prospective register of systematic reviews, with the registration number CRD42023394673. A literature search was conducted in PubMed, Scopus, and Web of Science. Cross-sectional studies published in English from the inception of each database to February 06th 2023 and focused on healthy individuals practicing spontaneous PA/exercise at home during the pandemic were considered eligible. The quality assessment was performed using the adapted Newcastle-Ottawa Quality Assessment Scale. Bibliographic information, sample size, study paricipant/population with age, gender, ethnicity, socioeconomic status, education, smart workers or not, anthropometric parameters, characteristics of at home exercises, athletic status and sedentariness, associated health-related effects, and main findings were synthetised.

RESULTS

From 504 articles, 19 were included. Notwithstanding the differences in the studies examined, the majority of them reported that previous PA level was associated with exercise in such challenging conditions. Furthermore, technologies aimed at supporting exercise were shown to be a useful resource.

CONCLUSIONS

Being habitually active and using digital supports may be associated with a positive attitude towards exercise at home during isolation. This suggests that in emergency situations, exercise should be promoted, also through digital media, especially among those groups who are usually less engaged in PA. Further analyses of longitudinal studies are needed to confirm these findings.

The COVID-19 Pandemic and Elective Spine Surgery-A Single Center Experience

Background and objective: The COVID-19 pandemic had a profound impact on medical practice worldwide. In this study, we aimed to investigate the trends of elective spine surgery in our department before and during the pandemic. Materials and methods: Total number of spine procedures due to disc herniation (DH) or spinal stenosis (SS) was collected during 2019-2021 in the Department of Neurosurgery, University Hospital Center Osijek, Croatia. In order to elucidate potential risk factors in the post-pandemic period, demographic data were collected for patients who underwent surgery during 2021. Results: In 2020, there was a 22.1% decrease in the number of surgeries compared to 2019 (205 vs. 263), but during 2021 we observed an increase of 36.1% compared to 2020 (279 vs. 205). The mean age of patients in 2021 was 53.14 years (53.14 ± 13.05) with body mass index of 28.31 kg/m2 (28.31 ± 4.89). There were 179 overweight patients (74%) and 103 smokers (42.6%). Although male and female patients were equally represented (121 each), there was a significant interaction of weight class and sex (p = 0.013). Patients younger than 65 were more likely to undergo surgery due to DH (p < 0.001), whereas older patients were more likely to suffer from SS (p < 0.001). Conclusions: The volume of elective spine surgeries decreased in the first year of the pandemic and increased the following year. Our results suggest that public health policies in the early pandemic period reduced elective surgical procedures, which was followed by a compensatory increase in the following period.

trips4health: a single-blinded randomised controlled trial incentivising adult public transport use for physical activity gain

BACKGROUND

Public transport users tend to accumulate more physical activity than non-users; however, whether physical activity is increased by financially incentivising public transport use is unknown. The trips4health study aimed to determine the impact of an incentive-based public transport intervention on physical activity.

METHODS

A single-blinded randomised control trial of a 16-week incentive-based intervention involved Australian adults who were infrequent bus users (≥ 18 years; used bus ≤ 2 times/week) split equally into intervention and control groups. The intervention group were sent weekly motivational text messages and awarded smartcard bus credit when targets were met. The intervention group and control group received physical activity guidelines. Accelerometer-measured steps/day (primary outcome), self-reported transport-related physical activity (walking and cycling for transport) and total physical activity (min/week and MET-min/week) outcomes were assessed at baseline and follow-up.

RESULTS

Due to the COVID pandemic, the trial was abandoned prior to target sample size achievement and completion of all assessments (N = 110). Steps/day declined in both groups, but by less in the intervention group [-557.9 steps (-7.9%) vs.-1018.3 steps/week (-13.8%)]. In the intervention group, transport-related physical activity increased [80.0 min/week (133.3%); 264.0 MET-min/week (133.3%)] while total physical activity levels saw little change [35.0 min/week (5.5%); 25.5 MET-min/week (1.0%)]. Control group transport-related physical activity decreased [-20.0 min/week (-27.6%); -41.3 MET-min/week (-17.3%)], but total physical activity increased [260.0 min/week (54.5%); 734.3 MET-min/week (37.4%)].

CONCLUSION

This study found evidence that financial incentive-based intervention to increase public transport use is effective in increasing transport-related physical activity These results warrant future examination of physical activity incentives programs in a fully powered study with longer-term follow-up.

TRIAL REGISTRATION

This trial was registered with the Australian and New Zealand Clinical Trials Registry August 14th, 2019: ACTRN12619001136190; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=377914&isReview=true.

Eighteen-Month Changes in Physical Activity, Body Weight, Quadriceps Strength, and Gait Biomechanics during the COVID-19 Pandemic

PURPOSE

This study assessed the effects of the COVID-19 pandemic restrictions/lockdowns on physical activity levels, body mass, quadriceps strength, and gait biomechanics over 18 months.

METHODS

Ten healthy men were assessed at baseline (~14 wk before first lockdown) and 17.9 ± 0.3 months later (<1 wk after second lockdown). At both times, physical activity levels, body mass, and quadriceps strength were acquired using the International Physical Activity Questionnaire, a force plate, and a dynamometer, respectively. Gait data were also acquired using a motion capture system and force plates during self-paced walking, from which spatiotemporal parameters, knee angles, and external moments were computed. Baseline and follow-up measurements were compared using two-tailed paired t -tests ( α = 0.05).

RESULTS

At follow-up, participants spent less time doing vigorous physical activity (∆ = -76 ± 157 min·wk -1 , P = 0.048), exhibited a tendency toward increased sedentary time (∆ = +120 ± 162 min·d -1 , P = 0.056), weighed more (∆ = +2.5 ± 2.8 kg, P = 0.021), and showed a trend toward reduced quadriceps strength (∆ = -0.29 ± 0.45 (N·m)·kg -1 , P = 0.071) compared with baseline. At follow-up, participants walked slower (∆ = -0.09 ± 0.07 m·s -1 , P = 0.005), had greater knee flexion angles at heel strike (∆ = +2.2° ± 1.8°, P = 0.004) and during late stance (∆ = +2.2° ± 1.8°, P = 0.004), had reduced knee extension moments (∆ = -0.09 ± 0.09 (N·m)·kg -1 , P = 0.012) and knee internal rotation moments (∆ = -0.02 ± 0.02 (N·m)·kg -1 , P = 0.012) during late stance.

CONCLUSIONS

Healthy men exhibited reduced physical activity levels, increased body weight, a tendency toward reduced quadriceps strength, and altered gait biomechanics over the initial 18 months of the COVID-19 pandemic-alterations that could have far-reaching health consequences.

Physical activity and mental health in children and youth during COVID-19: a systematic review and meta-analysis

BACKGROUND

The coronavirus disease (COVID-19) and universal mitigation strategies have fundamentally affected peoples' lives worldwide, particularly during the first two years of the pandemic. Reductions in physical activity (PA) and increased mental health (MH) problems among children and youth have been observed. This systematic review and meta-analysis investigated the relationship between physical activity (PA) and mental health (MH) among children and youth during the COVID-19 pandemic.

METHODS

Four electronic databases (EMBASE, PsycINFO, PubMed, and Web of Science) were systematically searched to identify studies that (1) examined the relationship between PA and MH among children and youth (aged 2-24 years old) and (2) were published in peer-reviewed journals in English between January 2020 and December 2021. Relationships between PA and two MH aspects (i.e., negative and positive psychological responses) among children and youth at different age ranges and those with disabilities or chronic conditions (DCC) were synthesized. Meta-analyses were also performed for eligible studies to determine the pooled effect size.

RESULTS

A total of 58 studies were eventually included for variable categorization, with 32 eligible for meta-analyses. Our synthesis results showed that greater PA participation was strongly related to lower negative psychological responses (i.e., anxiety, depression, stress, insomnia, fatigue, and mental health problems) and higher positive psychological responses (i.e., general well-being and vigor) in children and youth during COVID-19. The pattern and strength of relations between PA and MH outcomes varied across age ranges and health conditions, with preschoolers and those with DCC receiving less attention in the existing research. Meta-analysis results showed that the magnitude of associations of PA with negative (Fisher's z = - 0.198, p < 0.001) and positive (Fisher's z = 0.170, p < 0.001) psychological responses among children and youth was weak. These results were linked to age of participants, study quality, and reporting of PA-related information.

CONCLUSIONS

PA participation and MH among children and youth deteriorated during the COVID-19 pandemic and were closely associated with each other. For the post-COVID-19 era, additional research on age- and health condition-specific relationships between PA and MH outcomes from a comprehensive perspective is warranted. (Word count: 344 words).

Trends in insufficient physical activity among adults in China 2010-18: a population-based study

BACKGROUND

The global prevalence of insufficient physical activity (PA) was reported to be 27.5% in 2016, and there were stable levels of insufficient PA worldwide between 2001 and 2016. The global target of a 10% reduction in insufficient PA by 2025 will not be met if the trends remain. The relevant data for trends in China were still scarce. This study aimed to determine nationwide temporal trends in insufficient PA among adults in China from 2010 to 2018.

METHODS

645 903 adults aged 18 years or older were randomly selected from four nationally representative cross-sectional surveys of the China Chronic Disease and Risk Factor Surveillance conducted in 2010, 2013, 2015, and 2018. PA was measured using the Global Physical Activity Questionnaire. Temporal changes in insufficient PA prevalence and participation of domain-specific moderate- to vigorous-intensity PA (MVPA) were analyzed using logistic regression.

RESULTS

From 2010 to 2018, the age-adjusted prevalence of insufficient PA in China increased from 17.9% (95% confidence interval 16.3% to 19.5%) in 2010 to 22.3% (20.9% to 23.8%) in 2018 (P for trend < 0.001). By age group, with a significant increase in insufficient PA in adults aged 18-34 years (P for trend < 0.001), which rose more rapidly than in adults aged ≥ 35 years (P for interaction < 0.001). Insufficient PA has increased significantly among adults engaged in agriculture-related work, non-manual work, and other manual work (all P for trend < 0.05). And among the occupational groups, those engaged in agriculture-related work had the fastest increase (P for interaction = 0.01). The percentage of adults participating in work-related MVPA decreased from 79.6% (77.8% to 81.5%) to 66.8% (64.9% to 68.7%) along with a decrease in time spent on work-related MVPA, while percentages of adults participating in recreation-related MVPA increased from 14.2% (12.5% to 15.9%) to 17.2% (16.0% to 18.4%) (all P for trend < 0.05).

CONCLUSIONS

Among Chinese adults, an increasing trend was found in insufficient PA from 2010 to 2018, with more than one-fifth of adults failing to achieve the recommendation of adequate PA. More targeted PA promotion strategies should be developed to improve population health.

Health Behaviors during the Early COVID-19 Containment Phase and Their Impact on Psychological Health

The COVID-19 lockdowns have brought significant changes to individuals' daily lives, including their health behaviors and psychological health. Longitudinal studies exploring changes in health behaviors during the course of the initial containment phase are relatively scarce. Our aim is to understand how health behaviors have evolved during different phases of the early COVID-19 lockdowns and assess the impact of these changes on psychological well-being. By doing so, we hope to provide valuable insights that can enhance the understanding of the relationship between health behaviors and psychological health, with relevance not only to everyday life but to times of crises. A longitudinal study among 313 adults in Israel (44.5 ± 13.4 years old, 80% women) at three timepoints, beginning with the first COVID-19 lockdown (April 2020) and extending through June 2020. In each wave, participants were asked to report about exercising, eating fruits and vegetables, sharing family meals, and screen time. The BSI (Brief Symptom Inventory) was used to assess psychological health. There was an initial increase in the frequency of exercising (3.06 + 2.3 times a week) and shared meals (breakfast, 3.97 + 2.3; lunch, 5.30 + 1.9; dinner, 5.75 + 1.7 times a day) followed by a subsequent significant decrease in these behaviors (exercising, 2.84 + 2.0; breakfast, 2.63 + 2.1; lunch, 3.48 + 2.3; dinner, 4.75 + 2.0). The health behaviors of more exercising (r = -0.145, p = 0.43) and less screen time (r = 0.183, p = 0.010) had a positive impact on psychological health. External events, such as the first COVID-19 lockdown, may influence health behaviors which may, in turn, influence psychological health. While prior studies have mainly highlighted the negative impact of the pandemic on health behaviors, our analyses suggest that the first containment phase may have had an initial beneficial impact on several health behaviors, including exercising and family meals. However, this change was not sustainable.

Effect of Human Adenovirus 36 on Response to Metformin Monotherapy in Obese Mexican Patients with Type 2 Diabetes: A Prospective Cohort Study

Human adenovirus 36 (HAdV-36) has been associated with obesity and changes in glucose and lipid metabolism. The virus has been reported to increase insulin sensitivity and paradoxically promote weight gain. Because of its effects on metabolism, infection with the virus could alter the response to several drugs used to treat type 2 diabetes (DM2), such as metformin. The aim of this study was to test whether HAdV-36 affects the response to metformin in a group of obese patients with DM2.

METHODS

In a prospective cohort study, 103 obese patients with newly diagnosed DM2 were divided into two groups based on their HAdV-36 seropositivity (+HAdV-36 and -HAdV-36). Weight, glucose, cholesterol, triglycerides, body mass index, body fat percentage, and waist and hip circumference were measured and compared in both groups at baseline and after 45 days of metformin treatment.

RESULTS

Only glucose was significantly lower in the +HAdV-36 group at baseline, while all other variables were similar between the two study groups. After 45 days of follow-up, it was observed that the effect of metformin did not differ between the groups, but the variables improved significantly after treatment.

CONCLUSIONS

In this study, we did not find that HAdV-36 had an effect on the response to metformin in obese patients with DM2.

Association between physical activity education and prescription during prenatal care and maternal and fetal health outcomes: a quasi-experimental study

BACKGROUND

Physical activity (PA) during pregnancy is associated with healthy gestational weight gain (GWG) and a reduced risk of developing gestational diabetes (GD), gestational hypertension (GHT) and fetal macrosomia. However, in Canada, less than 20% of pregnant women meet PA recommendations. This study assessed associations between an intervention including PA education by prenatal nurses and a PA prescription delivered by physicians and fetal and maternal outcomes.

METHODS

This is a quasi-experimental study. Two groups of women who received their prenatal care at the obstetrics clinic of a university hospital were created. In the first group, 394 pregnant women followed at the clinic received standard care. In the second group, 422 women followed at the clinic received standard care supplemented with education on the relevance of PA during pregnancy and a prescription for PA. Data for both study groups were obtained from the medical records of the mothers and their newborns. Logistic regressions were used to compare the odds of developing excessive GWG, GD, GHT, and fetal macrosomia between the two study groups.

RESULTS

The addition of PA education and PA prescription to prenatal care was associated with 29% lower odds of developing excessive GWG (adjusted odds ratios (OR) 0.71, 95% confidence intervals (CI) 0.51-0.99), 73% lower odds of developing GHT (0.27, 0.14-0.53), 44% lower odds of fetal macrosomia (> 4 kg) (0.56, 0.34-0.93), and 40% lower odds of being large for gestational age (0.60, 0.36-0.99). The intervention was not associated with a difference in odds of developing GD (0.48, 0.12-1.94).

CONCLUSIONS

The inclusion of education and prescription of PA as part of routine prenatal care was associated with improvements in maternal and fetal health outcomes, including significantly lower odds of GWG, GHT and macrosomia.

A prospective study of the impact of COVID-19-related restrictions on activities and mobility upon physical activity, travel behaviour and attitudes

Background and aims

Public health measures adopted to contain the spread of COVID-19 included restrictions on activities and mobility as people were asked to stay at home and schools moved to online learning. This may have increased risk of non-communicable disease by limiting recreational and transport-related physical activity. Building on an existing study, we assessed changes in self-reported and device-measured physical activity and travel behaviour before, during and after the peak of local COVID-19 outbreak and restrictions (March-July 2020). We examined beliefs in effectiveness of strategies to increase active and public transport after restrictions were reduced.

Methods

A longitudinal study of adult infrequent bus users (average ≤ 2 trips per week; n = 70; 67% women) in Hobart, Australia. One-week assessment periods at four separate timepoints (before, during, 0-3 months after, and 3-6 months after the peak restrictions period) involved wearing an accelerometer, daily transport diaries, online surveys and tracking bus smartcard boardings.

Results

Physical activity (especially among older participants), bus use and private motor vehicle use declined significantly during or 0-3 months after the peak restrictions period and returned to pre-restrictions levels by 3-6 months after the peak restrictions period, except bus use which remained significantly lower. Retrospective surveys overstated declines in bus use and active transport and self-reports understated declines in physical activity. Social distancing and improving service efficiency and frequency were seen as effective strategies for increasing bus use after restrictions but belief in effectiveness of distancing decreased over time.

Conclusions

When restrictions on mobility are increased, supportive health promotion measures are needed to prevent declines in physical activity, particularly for older adults. Public transport systems need capacity to implement temporary distancing measures to prevent communicable disease transmission. Providing convenient, flexible, and efficient options for public transport may help to replenish public transport use after restrictions are reduced.

Is COVID-19 to Blame? Trends of Incidence and Sex Ratio in Youth-Onset Type 2 Diabetes in Germany

OBJECTIVE

We investigated the incidence of pediatric type 2 diabetes (T2D) in Germany during 2 years of the coronavirus disease 2019 (COVID-19) pandemic (2020-2021) compared with the control period 2011-2019.

RESEARCH DESIGN AND METHODS

Data on T2D in children (aged 6 to <18 years) were obtained from the DPV (German Diabetes Prospective Follow-up) Registry. Poisson regression was used to estimate incidences for 2020 and 2021 based on data from 2011 to 2019, and these were compared with observed incidences in 2020 and 2021 by estimating incidence rate ratios (IRRs) with 95% CIs.

RESULTS

Incidence of youth-onset T2D increased from 0.75 per 100,000 patient-years (PYs) in 2011 (95% CI 0.58, 0.93) to 1.25 per 100,000 PYs in 2019 (95% CI 1.02, 1.48), an annual increase of 6.8% (95% CI 4.1, 9.6). In 2020, T2D incidence increased to 1.49 per 100,000 PYs (95% CI 1.23, 1.81), which was not significantly higher than predicted (IRR 1.15; 95% CI 0.90, 1.48). In 2021, the observed incidence was significantly higher than expected (1.95; 95% CI 1.65, 2.31 vs. 1.38; 95% CI 1.13, 1.69 per 100,000 PYs; IRR 1.41; 95% CI 1.12, 1.77). Although there was no significant increase in incidence in girls in 2021, the observed incidence in boys (2.16; 95% CI 1.73, 2.70 per 100,000 PYs) significantly exceeded the predicted rate (IRR 1.55; 95% CI 1.14, 2.12), leading to a reversal of the sex ratio of pediatric T2D incidence.

CONCLUSIONS

In Germany, incidence of pediatric T2D increased significantly in 2021. Adolescent boys were more affected by this increase, resulting in a reversal of the sex ratio of youth-onset T2D.

The impact of the COVID-19 pandemic on physical activity and sleep among healthy adults: a systematic review and meta-analysis

Background

The COVID-19 pandemic has had a significant impact on physical and mental health, while physical activity and sleep are two important indicators of the impact that have been explored in recent studies. However, the results of studies with different measurement methods and populations with different levels of physical activity have been diverse in that physical activity and sleep are affected by the COVID-19 pandemic in some studies but not in others. Our study aimed to investigate the impact of the COVID-19 pandemic on physical activity and sleep and the role of measurement methods and populations on results.

Methods

PubMed, Web of Science, and CNKI databases were used to search for related studies systematically. Study characteristics and data on physical activity and sleep were collected and analyzed from each included study. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to estimate pooled effect sizes.

Results

A total of 13 articles were included in the systematic review, 11 of which were included in the meta-analysis. We found that moderate-to-vigorous physical activity (MVPA) time was 0.33 (95% CI 0.07 to 0.59) and sleep quality was 0.37 (95% CI 0.21 to 0.53) decreased, while sleep duration was -0.24 (95% CI -0.28 to -0.20) increased during the lockdown; overall physical activity time had no significant difference (p = 0.07) during the lockdown. The "wearables" subgroup had no heterogeneity (p = 0.89, I² = 0) in sleep duration, while MVPA time measured by subjective scales was not significantly changed. The "elite athletes" subgroup had lower heterogeneity (p = 0.69, I² = 0) in sleep duration than general adults, while the results of sleep quality for population subgroups were significant and there was no heterogeneity within either.

Conclusion

The COVID-19 pandemic had a significant impact on MVPA time, sleep duration, and sleep quality, instead of overall physical activity time among healthy adults. The results of MVPA time and sleep duration were greatly influenced by the measurement methods, and sleep behavior differed among populations with varying physical activity levels. Thus, when researching physical activity, especially MVPA time, should consider measurement methods, and more attention should be given to differences in populations when researching sleep behavior.

Personalized training as a promoter for physical activity in people with depressive disorder-a randomized controlled trial in Germany

Introduction

Adopting an active lifestyle is an important goal, but can be difficult to achieve for people with depressive disorders. Current guidelines recommend the integration of physical activity in the multimodal treatment of depressive disorders. However, the possibilities to provide individual support for physical activities are frequently limited. The aim of our study was to examine how physical activity can be increased in a real-world setting by combining physical training and psychological interventions.

Materials and methods

In this randomized-controlled interventional study, 31 outpatients diagnosed with moderate to severe depression were recruited from the region of Hannover. The intervention group (n = 16) was offered six weekly individual sessions lasting between 60 and 90  min with a sports scientist, including Motivational Interviewing and accompanied exercise activities. The control group (n = 15) received a written booklet with information on steps toward becoming more active. Moderate-to-vigorous physical activity (MVPA) as the primary outcome was analyzed using activity sensors before and after the 6-week intervention, and 3  months subsequently. Secondary outcomes included the Six-Minute Walk Test (6MWT), Sit-to-Stand test (STS), and mental health assessed with self-rating questionnaires.

Results

In the intervention group, MVPA increased significantly between baseline and the first follow-up and remained at an increased level at the second follow-up in comparison to decreased levels in the control group (difference of 15.5  min/day between groups over time, SE = 6.2  min/day, 95%-CI[2.7, 28.3], p = 0.020). The increased activity level was associated with markers of increased fitness (6MWT and STS) in the intervention group. Both groups showed comparable improvements in depressive symptoms, while the number of patients receiving antidepressants increased in the control group and decreased in the intervention group. Two patients dropped out of the intervention group during the trial.

Conclusion

The intervention proved to be a feasible and effective aid to promote a physically active lifestyle for patients diagnosed with depression. Furthermore, the higher level of physical activity was maintained for the follow-up period. Given the success of the approach evaluated in this project, individual support for physical activity should be investigated in larger sample sizes and potentially be considered in the multimodal treatment of depression.

The association between psychological distress and alcohol consumption and physical activity: a population-based cohort study

Introduction

The COVID-19 pandemic and infection control measures caused changes to daily life for most people. Heavy alcohol consumption and physical inactivity are two important behavioral risk factors for noncommunicable diseases worldwide. The COVID-19 pandemic, with its social distancing measures, home office policies, isolation, and quarantine requirements may have an impact on these factors. This three-wave longitudinal study aims to investigate if psychological distress and worries related to health and economy were associated with levels and changes in alcohol consumption and physical activity during the two first years of the COVID-19 pandemic in Norway.

Methods

We used data collected in April 2020, January 2021, and January 2022 from an online longitudinal population-based survey. Alcohol consumption and physical activity status were assessed at all three measuring points via the Alcohol Use Disorder Identification Test (AUDIT-C) and the International Physical Activity Questionnaire (IPAQ-SF). COVID-19-related worries, home office/study, occupational situation, age, gender, children below 18 years living at home, and psychological distress (measured with the Symptom Checklist (SCL-10)) were included as independent variables in the model. A mixed model regression was used and presented with coefficients with 95% confidence intervals (CI).

Results

Analysis of data from 25,708 participants demonstrates that participants with substantial symptoms of psychological distress more often reported higher alcohol consumption (1.86 units/week, CI 1.48-2.24) and lower levels of physical activity [-1,043 Metabolic Equivalents of Task (METs) per week, CI -1,257;-828] at baseline. Working/studying from home (0.37 units/week, CI 0.24-0.50) and being male (1.57 units/week, CI 1.45-1.69) were associated with higher alcohol consumption. Working/studying from home (-536 METs/week, CI -609;-463), and being older than 70 years (-503 METs/week, CI -650;-355) were related to lower levels of physical activity. The differences in activity levels between those with the highest and lowest levels of psychological distress reduced over time (239 METs/week, CI 67;412), and similarly the differences in alcohol intake reduced over time among those having and not having children < 18 years (0.10 units/week, CI 0.01-0.19).

Conclusion

These findings highlight the substantial increases in risks related to inactivity and alcohol consumption among those with high levels of psychological distress symptoms, and particularly during the COVID-19 pandemic, and increase the understanding of factors associated with worries and health behavior.

Physical activity and long COVID: findings from the Prospective Study About Mental and Physical Health in Adults cohort

OBJECTIVES

The study investigated the longitudinal association between physical activity and the risk of long COVID in patients who recovered from COVID-19 infection.

STUDY DESIGN

We analyzed longitudinal data of the Prospective Study About Mental and Physical Health cohort, a prospective cohort study with adults living in Southern Brazil.

METHODS

Participants responded to an online, self-administered questionnaire in June 2020 (wave 1) and June 2022 (wave 4). Only participants who self-reported a positive test for COVID-19 were included. Physical activity was assessed before (wave 1, retrospectively) and during the pandemic (wave 1). Long COVID was assessed in wave 4 and defined as any post-COVID-19 symptoms that persisted for at least 3 months after infection.

RESULTS

A total of 237 participants (75.1% women; mean age [standard deviation]: 37.1 [12.3]) were included in this study. The prevalence of physical inactivity in baseline was 71.7%, whereas 76.4% were classified with long COVID in wave 4. In the multivariate analysis, physical activity during the pandemic was associated with a reduced likelihood of long COVID (prevalence ratio [PR]: 0.83; 95% confidence interval [CI]: 0.69-0.99) and a reduced duration of long COVID symptoms (odds ratio: 0.44; 95% CI: 0.26-0.75). Participants who remained physically active from before to during the pandemic were less likely to report long COVID (PR: 0.74; 95% CI: 0.58-0.95), fatigue (PR: 0.49; 95% CI: 0.32-0.76), neurological complications (PR: 0.47; 95% CI: 0.27-0.80), cough (PR: 0.40; 95% CI: 0.22-0.71), and loss of sense of smell or taste (PR: 0.43; 95% CI: 0.21-0.87) as symptom-specific long COVID.

CONCLUSION

Physical activity practice was associated with reduced risk of long COVID in adults.

Barriers, Facilitators, and Strategies for Developing a Culturally Informed Lifestyle Intervention for Native Hawaiian, CHamoru, and Filipino Breast Cancer Survivors: Mixed-Methods Findings from Focus Group Participants

Breast cancer disproportionately impacts Native Hawaiian, CHamoru, and Filipino women. Few culturally informed interventions addressing breast cancer survivors exist and none have been developed or tested specifically for Native Hawaiian, CHamoru, and Filipino women. This study aimed to conduct focus groups with Native Hawaiian, CHamoru, and Filipino women previously diagnosed with breast cancer to inform future research in Guam and Hawai'i. Convenience sampling and grounded theory approaches were used. Focus group sessions were conducted during summer 2023 and included questions to understand the barriers, motivators, and implementation recommendations for lifestyle interventions aimed at reducing the risk for breast cancer recurrence among the target population. Data saturation was reached after a total of seven focus groups (an average of four survivors/group per site) were conducted (three in Hawai'i and four in Guam), which represented 28 breast cancer survivors. Themes from the focus groups emerged around developing support systems with other survivors, providing physical activity and nutrition intervention activities and materials in multiple formats, and incorporating activities and foods that accommodate the side effects of breast cancer treatments and are culturally relevant. The average desired intervention length was eight weeks. These findings will inform the development and feasibility testing of a culturally informed lifestyle intervention for breast cancer survivors in Guam and Hawai'i.

Physical, psychological, and behavioral problems among children and adolescents in countries with different economic statuses during the COVID-19 pandemic: a systematic review and meta-analysis

Introduction

The COVID-19 pandemic has impacted children and adolescents' physical activity (PA), sleeping patterns, and psychological and behavioral health. Yet, little is known about the differences between those in countries with various economic statuses.

Methods

Articles published from database inception through 16 March 2022 were retrieved using CINAHL Complete, Cochrane Library, EMBASE, Medline, PubMed, and PsycINFO. High-quality studies that reported the number of participants with parameters associated with PA, sleeping patterns, and psychological and behavioral problems in young people aged under 18 years during the pandemic were included. We referenced the Canadian 24-Hour Movement Guidelines for PA and sleep duration to provide the event rate for young people who were not compliant with the guidelines. The event rate of young people who had decreased sleep quality and experienced psychological and behavioral problems were also investigated. A subgroup analysis was conducted to identify the differences in those in countries with diverse economic statuses. Funnel plot analysis and Egger's test were also conducted to identify any risk of publication bias.

Result

A total of 66 studies with 1,371,168 participants aged between 0 and 18 years, involving 27 countries, were included. During the pandemic, we identified that 41% (95% CI: 39%, 43%; I2 = 96.62) and 43% (95% CI: 34%, 52%; I2 = 99.42) of young people did not meet the PA and sleep duration recommendation guidelines. In addition, 31% (95% CI: 28%, 35%; I2 = 99.66) of young people had decreased their sleep quality. Yet, no significant difference was found across countries with different economic statuses. However, the event rates of participants with psychological and behavioral problems were 32% (95% CI: 28%, 36%; I2 = 99.85) and 19% (95% CI: 14%, 25%; I2 = 99.72), respectively. In addition, the rate of psychological problems was more severe in those who live in lower middle-income countries (p < 0.001), while the rate of behavioral problems was more severe in those who live in high-income countries (p = 0.001).

Discussion

During the pandemic, the discouragement of PA, poor sleep quality, and high risk of psychological and behavioral problems are concerning. A large number of young people did not comply with the recommendation guidelines. Timely implementation of recovery plans is critical to address the adverse effects on young people.

National Trends in Physical Activity Among Adults in South Korea Before and During the COVID-19 Pandemic, 2009-2021

Importance

There is a lack of comprehensive data on the association of the COVID-19 pandemic with the prevalence of physical activity in large-scale data sets.

Objective

To investigate long-term trends in physical activity using information from a nationally representative survey covering 2009 to 2021.

Design, Setting, and Participants

This general population-based and repeated cross-sectional study was conducted from 2009 to 2021 using the Korea Community Health Survey, a nationally representative survey in South Korea. Data from 2009 to 2021 for 2 748 585 Korean adults were obtained through a nationwide, large-scale, serial study. Data were analyzed from December 2022 through January 2023.

Exposure

COVID-19 pandemic onset.

Main Outcomes and Measures

The trend of sufficient aerobic physical activity was measured by prevalence and mean metabolic equivalent of task (MET) score based on World Health Organization physical activity guidelines and defined as 600 MET-min/wk or greater. The cross-sectional survey included age, sex, body mass index (BMI), region of residence, education level, income level, smoking status, alcohol consumption level, stress status, physical activity level, and history of diabetes, hypertension, and depression.

Results

Among 2 748 585 Korean adults (738 934 aged 50-64 years [29.1%] and 657 560 aged ≥65 years [25.9%]; 1 178 869 males [46.4%]), the prevalence of sufficient physical activity did not change significantly during the prepandemic period (β difference, 1.0; 95% CI, 0.6 to 1.4). During the pandemic, the prevalence of sufficient physical activity decreased significantly, from 36.0% (95% CI, 35.9% to 36.1%) in 2017 to 2019 to 30.0% (95% CI, 29.8% to 30.2%) in 2020 and 29.7% (95% CI, 29.5% to 29.9%) in 2021. Trends showed decreases in the prevalence of sufficient physical activity among older adults (ages ≥65 years; β difference, -16.4; 95% CI, -17.5 to -15.3) and younger adults (ages 19 to 29 years; β difference, -16.6; 95% CI, -18.1 to -15.0) during the pandemic. In particular, the trend of sufficient physical activity declined during the pandemic in females (β difference, -16.8; 95% CI, -17.6 to -16.0), individuals in urban residences (β difference, -21.2; 95% CI, -22.2 to -20.2), healthy participants (eg, those with normal BMI, 18.5 to 22.9: β difference,-12.5; 95% CI, -13.4 to -11.7), and individuals at increased risk of stress (eg, history of a depressive episode; β difference, -13.7; 95% CI, -19.1 to -8.4). Prevalence trends in mean MET score were similar to those in the main results; total mean MET score decreased from the 2017 to 2019 period (1579.1 MET-min/wk; 95% CI, 1567.5 to 1590.7 MET-min/wk) to the 2020 to 2021 period (1191.9 MET-min/wk; 95% CI, 1182.4 to 1201.4 MET-min/wk.

Conclusions and Relevance

This cross-sectional study found that the national prevalence of physical activity was stable or consistent before the pandemic period, with a marked decrease during the pandemic, particularly among healthy individuals and subgroups at increased risk of negative outcomes, including older adults, females, urban residents, and those with depressive episodes. Future studies may be needed to evaluate the association between the COVID-19 pandemic and changes in physical activity.

Pet ownership and lifestyle behaviours of immunosuppressed individuals and their relatives in the context of COVID-19 pandemic

The COVID-19 pandemic and containment measures will likely have a detrimental impact on immunosuppressed individuals' lifestyle behaviours. Increasing evidence suggests that pet ownership is positively associated with healthier lifestyle. Yet, no study has investigated the potential benefits of pet ownership on lifestyle behaviours of immunosuppressed individuals, a population at increased risk of COVID-19 complications. This study aims to examine 1) changes in light, moderate and vigorous intensity physical activity (LPA, MPA, VPA), sedentary time (SED), and sleep duration, assessed by comparing "before COVID-19 pandemic" and "past 7 days" (i.e., current, during pandemic) self-reported behaviours in immunosuppressed individuals and their relatives; 2) to assess if changes in lifestyle behaviours are associated with pet ownership status and whether age is a moderator of these associations. A convenience sample of 132 participants (65.2% female, 41.3% ≥55 years of age) provided self-reported LPA, MPA, VPA (days/week), SED and sleep (min/day) and pet ownership status using an online questionnaire (May-August 2020). Descriptive analyses, paired T-tests, Cohen's d effect size and linear regressions were conducted. Results show that participants reported a decrease in VPA (-0.56 days/week, d = 0.34; p < 0.01) and an increase in SED (106.79 min/day, d = -0.81; p < 0.01). Stratified analysis revealed that having at least one dog, compared to not owning pets, is associated with a reduced decline in LPA, MPA and VPA and an increase in sleep in participants aged < 55 years old only. Having a dog appears to be positively associated with healthy lifestyle behaviours in younger and middle age immunosuppressed individuals.

The seasonal variation of physical activity and quality of life during the first wave of the COVID-19 pandemic in Finnish older golfers: A cross-sectional study

Background and Aims

The COVID-19 pandemic was associated with reduced physical activity and increased sedentary behavior. Golf is a health-enhancing outdoor exercise and is associated with low risk of viral transmission. The purpose of this study was to describe the seasonal differences in physical activity and quality of life during the first wave of COVID-19 pandemic in 2020 in Finnish older golfers.

Methods

Older golfers (n = 325) from eight golf clubs retrospectively responded to a questionnaire in summer 2020 on their physical activity and golf activity in winter 2019/20 (pre-COVID-19 winter season) and summer season 2020. In addition, they reported their quality of life after the first wave of pandemic in summer 2020. To evaluate the seasonal differences in physical activity, life quality and its association with golf activity, the data were analyzed using the Mann-Whitney U test, Wilcoxon signed-rank test, Spearman's correlation test, and linear regression analysis.

Results

Despite COVID-19 restrictions, golfers' physical activity increased by 24% (p < 0.001) during the COVID-19 restrictions in the summer of 2020. Moderate physical activity increased by 37% (p < 0.001), walking activity increased by 26% (p < 0.001), and sitting decreased by 21% (p < 0.001) compared with the pre-COVID-19 winter season. The full 18-hole golf round activity was positively associated with moderate physical activity both in the summer and winter season, and with walking in the summer season. Over 90% of golfers reported good quality of life during the 2020 summer restrictions.

Conclusion

In contrast to physical activity levels generally decreasing during the first wave of pandemic, physical activity levels in Finnish golfers increased, and these golfers reported a good quality of life. Golf can provide health enhancing physical activity and older golfers seems to be physically active throughout the year.

Development and evaluation of a school-based physical literacy intervention for children in Germany: protocol of the PLACE study

Introduction

Fueled by the COVID-19 pandemic, the physical activity behavior of children has reached a concerning level nowadays. By empowering individuals to be physically active throughout the life course, the concept of physical literacy has recently gained increasing attention and adopts a holistic-integrative perspective on PA promotion. Although the field has successively attempted to translate the conceptual ideas of physical literacy into interventions, the theoretical base is heterogeneous and is often lacking within interventions. Furthermore, several countries, including Germany, have not equally adopted the concept yet. Therefore, the goal of the present study protocol is to describe the development and evaluation approach of a PL intervention ("PLACE") for children in grades three and four within the German all-day schooling system.

Methods

The physical literacy intervention cultivates explicit theory-content links and comprises 12 heterogeneous sessions (each 60-90 min in length). The study contains three different phases with two initial pilot studies and a subsequent main study. The two pilot studies take a mixed-methods character by drawing on quantitative pre-post-designs as well as interviews with children (in groups). In the main study, we will longitudinally compare the course of PL values (five outcome domains: physical, affective, cognitive, social, behavioral) between two study arms: school classes of children are either assigned to an intervention condition (regular physical education and health care plus PL intervention) or to a control condition (regular physical education and health care only).

Discussion

The findings of this study will provide evidence on how to structure a multicomponent intervention in Germany based on the PL concept. In summary, the results will report on the effectiveness of the intervention and, therefore, decide whether to scale-up the intervention.

Physical fitness in Austrian elementary school children prior to and post-COVID-19

Background

With the emergence of the COVID-19 pandemic, many countries implemented policies that included movement restrictions, social distancing and school closures in order to control the spread of the virus. Even though these actions may have been necessary to save lives, there have been some unintended consequences that could affect future public health.

Methods

The present study uses data from more than 24,500 Austrian elementary school children (51.2% male) that participated in a state-wide fitness evaluation program, which was initiated in the 2016/17 school year. In addition to body weight and height, data on cardiorespiratory endurance, muscular power, speed, agility, flexibility and object control were collected from three cohorts prior to the implementation of movement restrictions (school years: 2016/17, 2017/18, 2018/19) and one cohort in 2022, after the majority of COVID-19 policies had been lifted.

Results

Body mass index percentiles were significantly higher in children post-COVID-19 (p < 0.01). Further, cardiorespiratory endurance, agility and flexibility were significantly lower post-COVID-19 compared to the years preceding movement restrictions (p ≤ 0.01), while absolute muscular strength was higher in the year 2022 (p < 0.01).

Conclusion

Given the detrimental effects of COVID-19 policies on physical fitness in children, additional efforts are necessary that include versatile opportunities for physical activity and the promotion of physical fitness in order to modify the observed negative health trajectories and ensure future public health.

Changes to physical activity behavior during the COVID-19 pandemic and their associated factors: a cross sectional survey of Mexican women

BACKGROUND

On March 24, 2020, the Mexican Government established social distancing measures to address the outbreak of the COVID-19 pandemic. The resulting home confinement affected daily lifestyle habits such as eating, sleeping, and physical activity (PA). The objectives of this study were to determine changes in PA behaviors among Mexican women due to the COVID-19 pandemic and to assess potential factors associated with these changes.

METHODS

This was a cross-sectional study based on an anonymous online questionnaire developed by the Task Force on Physical Activity for Persons with Disabilities (PAPD) within the International Society of Physical and Rehabilitation Medicine (ISPRM). Descriptive, quantitative statistics were used for data analysis. A Chi-squared (χ²) test was used to explore associations between dependent and independent variables.

RESULTS

A total of 1882 surveys were completed. Among the respondents, 53.3% declared that their PA was reduced during the pandemic, 26.6% reported similar PA behavior, and 20.1% declared that their PA had increased during the pandemic. Lower PA behavior during the pandemic was associated with lower education levels, stricter pandemic constraints, obesity, and lower self-perceived functioning levels. A statistically significant association between poorer self-perceived mental health and decreased PA behaviors was also found. Respondents who were younger, self-perceived as unimpaired, not overweight, and whose income was not impacted by COVID-19 were associated with higher levels of reported physical and mental health.

CONCLUSIONS

The study results identify disparities experienced in PA behavior during the COVID-19 pandemic among Mexican women and highlights the need for social support for PA participation.

Incidence of memory complaints during the COVID-19 pandemic in Southern Brazil: findings from PAMPA cohort

Population-level studies investigating the incidence of memory complaints during the COVID-19 pandemic are scarce.

Objective

This study aimed to examine the incidence of memory complaints over 15 months during the COVID-19 pandemic in adults from Southern Brazil.

Methods

Data from the PAMPA (Prospective Study about Mental and Physical Health in Adults) cohort, a longitudinal study with adults residing in Southern Brazil, were analyzed. An online-based, self-administered questionnaire was used to assess self-rated memory. Participants rated their memories as excellent, very good, good, fair, or poor. Incident memory complaints were defined as worse memory perception from baseline to follow-up. Cox proportional hazard models were used to identify factors associated with the increased risk of memory complaints.

Results

During follow-up, a cumulative incidence of 57.6% for memory complaints was observed. Female sex (hazard ratio [HR] 1.49; 95% confidence intervals [CI] 1.16-1.94), lack of access to prescribed medicine (HR: 1.54; 95%CI 1.06-2.23), and worsened anxiety symptoms (HR: 1.81; 95%CI 1.49-2.21) were associated with an increased risk of memory complaints. Regular practice of physical activity was associated with a reduced risk of memory complaints (HR: 0.65; 95%CI 0.57-0.74).

Conclusion

Since the COVID-19 pandemic, 6 in 10 adults in Southern Brazil have developed memory complaints. Factors including sex and lack of medications increased the risk of incident memory complaints. Physical activity reduced the risk of incident memory complaints during the COVID-19 pandemic.
