Exploring Physical Activity Levels in Patients with Cardiovascular Disease-A Preliminary Study.

Increased physical activity may prevent disease onset and severity in individuals with cardiovascular disease. However, studies evaluating physical activity in people with cardiovascular disease are limited. This prospective observational study aimed to objectively assess the level of physical activity in patients with cardiovascular disease and determine the actual extent of physical activity in their daily lives. Participants aged 20 years or older with cardiovascular disease at a cardiology clinic were included. Physical activity was measured using an activity meter with a three-axis acceleration sensor. Overall, 58 patients were included in the study. Household activities were found to be more frequent sources of physical activity. The step count was related to age and housework, while total physical activity and household activity were related to age and work. Locomotive activity was related to sex and housework. Total physical and household activities tended to decrease with age. These findings indicate the influence of work and household chores on physical activity and suggest that physical activity may be underestimated if household activity is not also assessed. These fundamental findings may provide clinical evidence to underpin physical activity for patients with cardiovascular disease.

Investigating physical activity levels in adults who are blind and vision impaired.

BACKGROUND: It is well established that meeting physical activity (PA) guidelines has a range of physical and mental health benefits. For people who are blind and vision impaired (BVI) there may be additional benefits in terms of social inclusion and the prevention of sight deterioration. OBJECTIVE: This study aimed to quantify PA levels, barriers to and motivators for PA in adults who are BVI. METHODS: PA levels, perceived barriers to, and motivators for PA were measured via questionnaire of 310 self-identifying BVI adults (n = 310 mean age = 29.77 ± 11.37, 55.8% male). RESULTS: PA levels were low, with 21.7% meeting PA guidelines. Median PA levels were not statistically significantly different between different age groups. There was no significant difference between genders, though mean days of PA for males was 0.382 days lower than for females. There was a significant difference between PA levels between the "no vision" (B1) and "useful vision" (B3) groups (p = 0.027), and the "no vision" (B1) and the "low vision" (B2) groups (p = 0.003). Transport (54.8%) and lack of access to enjoyable activities (47.0%) were the most commonly cited barriers, while "to relax" (36.4%) and "to have fun" (35.6%) were most commonly cited as very important motivators. CONCLUSIONS: This study provides a valuable insight into the low levels of PA that persist amongst adults with BVI. Future research should seek to gain a deeper understanding of the PA barriers, motivators and facilitators in this cohort.

Stroke related sarcopenia in individuals with different physical activity levels: A cross-sectional study.

BACKGROUND AND OBJECTIVE: Individuals after stroke are likely to deal with the possible development of sarcopenia and reduced physical activity levels. The purpose of this study was to compare sarcopenia of individuals with chronic stroke who were stratified according to their physical activity levels, and to evaluate the relationship between sarcopenia and physical activity levels. MATERIALS AND METHODS: This cross-sectional study was conducted with individuals after chronic stroke recruited from the general community. Individuals were submitted to sarcopenia screening (SARC-F questionnaire) and assessment of physical activity levels (Human Activity Profile questionnaire) to classify the individuals as impaired, moderately active, and active according to their Adjusted Activity Status (AAS). ANOVA was used to investigate the sarcopenia between groups and Pearson's coefficient to investigate the association among variables. RESULTS: Fifty-four individuals with a mean age of 56 ± 17.4 years were included. Twenty-one percent of the individuals were screened for sarcopenia. Inactive individuals had higher mean scores in the SARC-F (3.6 ± 2.1 points), whereas moderately active and active individuals presented lower mean scores in the same questionnaire, being 1.2 ± 1.1 points and 0.5 ± 0.7 points, respectively. A statistically significant inverse and high association was found between sarcopenia and physical activity levels (r = -0.716; p < 0.01). CONCLUSION: Sarcopenia was found to be higher in individuals after chronic stroke with lower physical activity levels considered inactive when compared to individuals with higher physical activity levels. Furthermore, there was an inverse relationship between sarcopenia and physical activity level in stroke survivors.

Health-related physical fitness, physical activity and its correlates among school going adolescents in hilly state in north India: a cross sectional survey.

INTRODUCTION: Health-related physical fitness, which includes body composition, cardiorespiratory fitness, muscular endurance, flexibility, power, and strength are associated with risks of chronic diseases and promote good health and wellness. There have been reports of increasing levels of physical inactivity among children and adolescents, leading to increasing rates of obesity and decreased physical fitness. The present study was conducted among school going adolescents to estimate the levels and correlates of PF for timely intervention. METHODOLOGY: School based cross-sectional study was done among students of class 8-11th in Government schools of Garhwal division of Uttarakhand. Multistage stratified random sampling was applied for recruitment of study participants. We recruited a final sample size of 634 students. Validated questionnaires and standard methods for assessment of physical fitness, physical activity levels and other variables such as waist circumference, hip circumference, BMI and hemoglobin estimation were done. RESULTS: Average and above average cardiorespiratory fitness score as per Harvard step test among boys (54.3%) was significantly higher as compared to girls (21.3%) (χ2 = 88.93, p < 0.001). There was a significant association between gender and dominant handgrip strength (χ2 = 8.02, p = 0.01) as well as between gender and Shoulder stretch test (SST) of dominant (χ2 = 17.5, p < 0.05) as well as nondominant arm (χ2 = 13.5, p < 0.05). Sit and reach test results also showed a significant association with gender (χ2 = 27.17, p < 0.001). Gender, hemoglobin level, BMI and PAL scores significantly predicted cardiorespiratory fitness scores (R2 = 0.188, F value of the model = 37.69, p =< 0.001)). CONCLUSION: Physical fitness of school going adolescents in Garhwal division of Uttarakhand was better than other parts of India, with significant gender differences. Physical activity levels (PAL) were poor and are also a significant predictor of physical fitness. More emphasis needs to be paid on the health and fitness of girl students. School based policies to increase PAL among students through innovation and rewards may go a long way in improving the long-term health of the students.

Short-term effects of air pollution and weather on physical activity in patients with chronic obstructive pulmonary disease (COPD).

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) accumulate low levels of physical activity. How environmental factors affect their physical activity in the short-term is uncertain. AIM: to assess the short-term effects of air pollution and weather on physical activity levels in COPD patients. METHODS: This multi-center panel study assessed 408 COPD patients from Catalonia (Spain). Daily physical activity (i.e., steps, time in moderate-to-vigorous physical activity (MVPA), locomotion intensity, and sedentary time) was recorded in two 7-day periods, one year apart, using the Dynaport MoveMonitor. Air pollution (nitrogen dioxide (NO2), particulate matter below 10 µm (PM10) and a marker of black carbon (absorbance of PM2.5: PM2.5ABS), and weather (average and maximum temperature, and rainfall) were estimated the same day (lag zero) and up to 5 days prior to each assessment (lags 1-5). Mixed-effect distributed lag linear regression models were adjusted for age, sex, weekday, public holidays, greenness, season, and social class, with patient and city as random effects. RESULTS: Patients (85% male) were on average (mean ± SD) 68 ± 9 years old with a post-bronchodilator forced expiratory volume in 1 s (FEV1) of 57 ± 18% predicted. Higher NO2, PM10 and PM2.5ABS levels at lag four were associated with fewer steps, less time in MVPA, reduced locomotion intensity, and longer sedentary time (e.g., coefficient (95% CI) of -60 (-105, -15) steps per 10 µg/m3 increase in NO2). Higher average and maximum temperatures at lag zero were related to more steps and time in MVPA, and less sedentary time (e.g., +85 (15, 154) steps per degree Celsius). Higher rainfall at lag zero was related to fewer steps and more sedentary time. CONCLUSION: Air pollution affects the amount and intensity of physical activity performed on the following days in COPD patients, whereas weather affects the amount of physical activity performed on the same day.

Effect of an activity wristband-based intermittent teaching unit in Physical Education on students' physical activity and its psychological mediators: a cluster-randomized controlled trial. School-fit study.

Objective: The main objective of the present study was to examine the effects of an intermittent teaching unit based on the use of activity wristbands and behavior modification strategies on high school students' perceptions of autonomy support, satisfaction of basic psychological needs, motivation toward Physical Education and physical activity, intention to be physically active, and habitual physical activity levels. Materials and methods: An initial sample of 353 high school students (final sample = 175; 45.7% females; mean age = 13.3 ± 1.2 years) from two public high schools were cluster-randomly assigned into the intermittent (IG, n = 100) and control (CG, n = 75) groups. The IG performed an intermittent teaching unit twice a week for eight weeks. Specifically, the last 15 min of each lesson were used. As the main strategy to promote the practice of regular physical activity, students wore an activity wristband the whole day during the intervention period. Additionally, other behavior modification strategies were also applied (e.g., educational counseling, physical activity goals or reminders). Regarding the CG, during the intervention period (i.e,, the eight weeks that took place the intermittent teaching unit) they also performed two Physical Education sessions, but without using activity wristbands or other behavior modification strategies. Before and after the intervention, as well as at the end of the follow-up period (six weeks), students' physical activity practice mediators and physical activity levels were measured by validated questionnaires. Results: The Multilevel Linear Model results showed that the IG students statistically significantly improved cognitive and procedural autonomy support from pre- to post-intervention (p < 0.05). They also statistically significantly improved autonomy and relatedness basic psychological needs, and autonomous motivation toward physical activity scores from post-intervention to follow-up (p < 0.05). Moreover, the results showed that the IG students statistically significantly improved habitual physical activity scores from pre- to post-intervention, and from post-intervention to follow-up (p < 0.05). Conclusion: The intermittent teaching unit based on the use of activity wristbands and other behavior modification strategies was effective for improving students' autonomy support and habitual physical activity levels, but not the rest of physical activity practice mediators.

Factors associated with decreased physical activity levels among community-dwelling residents during the coronavirus disease 2019 pandemic: a long-term observational study.

[Purpose] The purpose of this study was to determine the factors associated with decreased physical activity levels among community residents over a long-term observation period during the coronavirus disease 2019 (COVID-19) pandemic. [Participants and Methods] We conducted a cross-sectional study using a self-administered questionnaire and daily steps as an indicator of physical activity levels. The study population consisted of 704 community-dwelling residents aged 40 years and older who participated in the health program from 2019 to 2020. We compared the daily steps from March-December 2019 to March-December 2020 and performed multivariate analysis to identify the factors associated with decreased daily steps. [Results] Of all participants, 447 (63.5%) returned the questionnaire and 309 (43.9%) were included in the analysis. During the COVID-19 pandemic, 133 (43.0%) respondents had decreased physical activity levels. The multivariate analysis showed that working (odds ratio, 2.08; 95% confidence interval, 1.10-3.94) was significantly associated with decreased daily steps during the COVID-19 pandemic. [Conclusion] There was a significant association between decreased physical activity levels and working during the COVID-19 pandemic. When restrictive measures such as teleworking are implemented, it may be necessary to take measures to prevent a decline in physical activity levels.

Impact of COVID-19 on dietary intake, sleeping patterns and physical activity levels among Malaysian University students.

OBJECTIVES: The COVID-19 pandemic has brought a significant impact on people's behaviour and lifestyles. Limited research has been conducted on the impact of COVID-19 on Malaysian university students' lifestyle modifications. This study aims to identify the impact of COVID-19 on dietary intake, sleeping patterns and physical activity levels among Malaysian university students. METHODS: A total of 261 university students were recruited. Sociodemographic and anthropometric data were collected. Dietary intake was assessed using PLifeCOVID-19 questionnaire, sleep quality was assessed using Pittsburgh Sleep Quality Index Questionnaire (PSQI) while physical activity level was assessed using International Physical Activity Questionnaire-Short Forms (IPAQ-SF). SPSS was used to perform statistical analysis. RESULTS: 30.7% of the participants adhered to the unhealthy dietary pattern, 48.7% had poor quality of sleep and 59.4% engaged in low physical activity levels during the pandemic. Unhealthy dietary pattern was significantly associated with a lower IPAQ category (p=0.013), and increased time spent sitting (p=0.027) during the pandemic. Participants being underweight before the pandemic (aOR=2.472, 95% CI=1.358-4.499), increased takeaway meal consumption (aOR=1.899, 95% CI=1.042-3.461), increased snacking between meals consumption (aOR=2.989, 95% CI=1.653-5.404) and engaged in a low level of physical activity during pandemic (aOR=1.935, 95% CI=1.028-3.643) were the predictors of unhealthy dietary pattern. CONCLUSIONS: The university students' dietary intake, sleeping patterns, and physical activity levels were impacted in different ways during the pandemic. Strategies and interventions should be developed and implemented to improve the dietary intake and lifestyle of the students.

Physical activity levels in people with Parkinson's disease treated by subthalamic nucleus deep brain stimulation.

PURPOSE: To explore the physical activity of people with Parkinson's disease (PD) with subthalamic nucleus deep brain stimulation (STN-DBS) and investigate factors associated with physical activity. METHODS: Twenty-four participants who had STN-DBS for one or more years were recruited. Eligibility criteria included Hoehn and Yahr stage ≤ 4, continuation of STN-DBS, living at home and able to provide informed consent. Physical activity was measured using the self-report physical activity scale for the elderly (PASE). Motor and non-factors that influence physical activity in PD, such as gait disturbance and mood, were recorded using clinical measures. RESULTS: Participants had long-standing PD of moderate severity, mean Hoehn and Yahr 2.3, and mild to moderate functional disability, MDS-UPDRS M-EDL mean 16.2. PASE scores were significantly lower compared to norms for adults ≤ 70 years (115.2 versus 143, p= 0.045). There was a significant negative correlation between PASE scores and falls history, fatigue, fear of falling (FOF) and quality of life (p < 0.05). CONCLUSIONS: This study provides further evidence that physical activity levels in PD with STN-DBS remain low compared to PASE norms for older adults. Future research investigating interventions to improve factors associated with low physical activity levels should be considered.Implications for RehabilitationDespite the benefits of deep brain stimulation (DBS) on motor function and activities of daily living, physical activity levels remain low in people with Parkinson's disease (PD) with subthalamic nucleus (STN)-DBS compared to norms for older adults.A history of falls, greater fear of falling (FOF) and higher levels of fatigue are associated with lower levels of physical activity in people with PD with STN-DBS.When planning rehabilitation interventions consideration should be given to strategies that promote and support regular physical activity for people with PD with STN-DBS.Rehabilitation clinicians should consider using falls prevention programmes and include strategies to decrease FOF for people with PD with STN-DBS.Consideration should be given to the presence of fatigue when planning the rehabilitation programme for the person with PD with STN-DBS.

Left Ventricular Diastolic Response to Isometric Handgrip Exercise in Physically Active and Sedentary Individuals.

Aims: This study aims to investigate the diastolic left ventricular (LV) response to isometric handgrip exercise among healthy middle-aged men with high physical activity levels, versus matched sedentary individuals. Methods: Two groups of 10 men aged 41−51 years were studied. Men in the first group had high weekly self-reported physical activity levels (>3000 METs × min/week). In comparison, men in the second group reported low physical activity levels (<300 METs × min/week). An isometric handgrip exercise (IHE) stress echocardiography test was performed in all of them. Results: Both groups showed a similar and statistically significant increase in heart rate, systolic, diastolic, and mean arterial pressure following IHE. The group of active men under study did not show a statistically significant change in the ratio of early diastolic mitral valve inflow velocity to early diastolic lateral wall tissue velocity (E/e' ratio) in response to IHE. Conversely, the inactive participants' E/e' ratio was higher at peak activity in the isometric handgrip exercise. Conclusions: Apparently, healthy middle-aged men with high levels of physical activity seem to have an improved lusitropic cardiac function compared to men with low levels of physical activity, as observed by the different diastolic LV responses induced by isometric handgrip exercise.

Who moves in vulnerable Caribbean neighborhoods? Positive deviance for physical activity: Findings from the Jamaica health and Lifestyle Survey 2017 (JHLS III).

Decreased physical activity (PA) has been associated with residents living in neighborhoods perceived as being disordered or having high crime levels. What is unknown are the characteristics of individuals who engage in moderate to vigorous levels of PA (MVPA) despite living in these vulnerable neighborhoods, or who may be referred to as positive deviants (PD). We examined the factors associated with PD for PA among Jamaicans. Between 2016 and 2017 the Jamaica Health and Lifestyle Survey, a cross-sectional nationally representative survey (n = 2807), was conducted on individuals aged 15 years and older. Regression analyses were performed to identify associations with PD, defined using engagement in MVPA among persons living in vulnerable neighborhoods (N = 1710). Being female (odds ratio [OR]a = 0.64 (0.48, 0.86); p = 0.003), obese while living in an urban area (ORa = 0.39; 95 % CI = 0.26, 0.59; p < 0.0001), unemployed (ORa = 0.53; 95 % CI = 0.39, 0.73; p < 0.0001), or a student (ORa = 0.62; 95 % CI = 0.39, 0.98); p = 0.041) was associated with a significantly lower likelihood of PD, while having a personal medical history of at least one chronic disease significantly increased likelihood (ORa = 1.43; 95 % CI = 1.08, 1.90; p = 0.014). Taking a PD approach may be one angle to consider in trying to determine what is working and for whom, so that this may be harnessed in policy, prevention and intervention programming to increase PA.

Associations between Self-Perceived and Desired Health-Related Physical Fitness in Spanish Children.

Health-related physical fitness (HRPF) has emerged as an important marker of health among children. It is usually defined as a multidimensional construct consisting of cardiorespiratory endurance; muscular strength and endurance; and flexibility. Currently, health policies are aimed at getting children to increase their HRPF levels. Understanding the relationship between the perceived and the desired levels of fitness can be important to avoid the abandoning of physical activity practice. We analyzed the associations between the self-perceived and the desired health-related physical fitness. A modified version of the self-perceived HRPF questionnaire was completed by 330 children (148 girls, mean age: 10.78 ± 0.67 years, and 182 boys, mean age: 10.82 ± 0.61 years). Fitness was measured through tests selected from the Eurofit battery. The questions regarding desired HRPF showed moderate internal consistency (Cronbach's α: 0.671) and good test-retest reliability (ICC: 0.761). In general, children shared a desire to improve their self-perceived HRPF. Those who perceived themselves as already being fit were the ones who showed the strongest desire for achieving higher HRPF levels.

Heart rate reactivity to acute mental stress is associated with adiposity, carotid distensibility, sleep efficiency, and autonomic modulation in young men.

Acute mental stress (AMS) increases heart rate (HR) and blood pressure. Since obesity can impair the cardiovascular reactivity to AMS, a better understanding of the mechanisms involved in this response is needed. We aimed to evaluate the cardiovascular reactivity to AMS in young men with normal or excess body fat. We also assessed the association between cardiovascular reactivity to AMS and cardiovascular risk factors, including autonomic modulation, carotid artery distensibility, physical activity levels, and sleep efficiency. Sixty-six young men (26.1 ± 4.1 years old) underwent anthropometric and body fat assessment (dual-energy X-ray absorptiometry) and had right-carotid artery ultrasonography. Accelerometers assessed physical activity levels and sleep efficiency. AMS was induced through the Stroop color-word test while blood pressure, HR, and cardiac interval were measured. Analyses were performed in Normal and Excess fat groups divided by fat mass index (FMI). Continuous data was used for multiple linear regression analyses. An interaction between FMI and time for HR reactivity was observed. Cardiac interval variability analysis showed that only participants with normal fat displayed parasympathetic withdrawal during AMS (P < 0.05). Multiple linear regression analysis supported the role of adiposity and autonomic modulation in the HR reactivity to AMS and showed involvement of carotid distensibility and sleep efficiency (P < 0.05). Carotid distensibility was the only predictor for blood pressure reactivity (P < 0.05). Physical activity was not associated with AMS's cardiovascular reactivity. We conclude that increased adiposity is associated with reduced HR reactivity to AMS, which is possibly linked to an impaired parasympathetic withdrawal. Carotid distension and sleep efficiency seem to contribute to this response.

Percepción del esfuerzo y niveles objetivos de intensidad en clases de Educación Física de escolares de primaria según sexo y estado nutricional: Estudio piloto / Perception of Effort and Objective Levels of Intensity in Physical Education Classes of Primary Schoolchildren According to Gender and Nutritional Status: A Pilot Study

Resumen El presente estudio aborda el análisis del esfuerzo percibido y tiempo en actividades de intensidad moderada y vigorosa en clases de Educación Física, considerando las diferencias según sexo y el estado nutricional de la persona estudiante. Participaron 95 estudiantes de 5° y 6° año de primaria de escuelas de la ciudad de Coyhaique, Chile. Se utilizó la escala EPInfant para la evaluación del esfuerzo percibido y acelerómetros Actigraph GT3X+ para determinar el tiempo en intensidad moderada y vigorosa. En el esfuerzo percibido no se encontraron diferencias significativas según sexo (p=0,144), pero sí según estado nutricional, siendo los estudiantes con obesidad quienes indican una percepción de esfuerzo mayor que el estudiantado de peso normal (p=0,022). En actividades moderadas y vigorosas dentro de la clase de Educación Física, los niños presentan significativamente más minutos en comparación a las niñas (p=0,017); mientras que los escolares normopeso presentarían levemente mayor tiempo en este nivel de intensidad, sin que esta diferencia sea estadísticamente significativa (p=0,622). El esfuerzo realizado en las clases de Educación Física ha sido percibido como más exigente por los escolares con obesidad, y para esto se deben comprender las dificultades físicas y motrices que este grupo presenta. Asimismo, las niñas han participado un menor tiempo en intensidades moderadas y vigorosas, por lo que es pertinente buscar estrategias que permitan aumentar el tiempo de su participación.

Abstract This study focuses on the analysis of perceived effort and time of moderate and vigorous activities in physical education classes, considering differences based on gender and the nutritional status of schoolchildren. A total of 95 children in 5th and 6th grade of primary school in the city of Coyhaique, Chile, participated in the study. The EPInfant scale was used to assess the perceived effort, and Actigraph GT3X+ accelerometers were used to determine the time of moderate and vigorous activity. No significant differences were found in the perceived effort by gender (p=0.144); instead, by nutritional status, obese students indicated a higher perceived effort than students with a normal weight (p=0.220). Regarding moderate and vigorous activities in Physical Education class, the boys were significantly more active than the girls (p=0.017). In contrast, normal-weight children were slightly more active at this intensity level, but this difference was not statistically significant (p=0.622). The effort in Physical Education classes has been perceived as more demanding by the obese students; for this reason, it is important to understand the physical and motor difficulties that this group presents. Likewise, girls have participated for a shorter time in moderate and vigorous intensities, being pertinent to look for didactic strategies to increase the time of their participation.

Resumo O presente estudo aborda a análise do esforço e do tempo percebido em atividades de intensidade moderada e vigorosa nas aulas de educação física, considerando as diferenças de acordo com o sexo e o estado nutricional de cada estudante. Participaram do estudo noventa e cinco alunos do 5º e 6º ano do ensino fundamental de escolas da cidade de Coyhaique, no Chile. A escala EPInfant foi utilizada para avaliar o esforço percebido e os acelerômetros Actigraph GT3X+ para determinar o tempo em intensidade moderada e vigorosa. Não foram encontradas diferenças significativas na percepção de esforço segundo o sexo (p=0,144), mas foram encontradas diferenças significativas segundo o estado nutricional, com estudantes obesos indicando uma percepção de maior esforço do que estudantes de peso normal (p=0,022). Nas atividades moderadas e vigorosas nas aulas de Educação Física, os meninos apresentam significativamente mais minutos que as meninas (p=0,017), enquanto os estudantes de peso normal apresentaram um pouco mais de tempo nesse nível de intensidade, embora essa diferença não tenha sido estatisticamente significativa (p=0,622). O esforço feito nas aulas de educação física foi percebido como mais exigente por estudantes obesos, e para isso é necessário compreender as dificuldades físicas e motoras que este grupo apresenta. Da mesma forma, as meninas têm participado por um tempo mais curto em intensidades moderadas e vigorosas, por isso é pertinente procurar estratégias para aumentar o tempo da sua participação.

Status of Sedentary Time and Physical Activity of Rural Residents: A Cross-Sectional Population-Based Study in Eastern China.

Background: The urbanization process may affect the lifestyle of rural residents in China. Limited information exists on the extent of sedentarism and physical activity (PA) level of rural residents in middle-income countries. This is the first survey on sedentary time (ST) and PA among rural residents in eastern China. Methods: This cross-sectional observational study randomly samples rural adults from Zhejiang Province in eastern China (n = 1,320). Participants' ST and PA levels were determined from the International Physical Activity Questionnaire Short Form through face-to-face interviews, and the influencing factors of PA levels were assessed through multi-class logistic regression analysis. Results: The findings showed that the daily ST of the participants ranged from 30 to 660 min, with a median of 240 min (P25, P75:120, 240 min), and 54.6% of participants were sedentary for 240 min or above. The daily ST in men, people aged 18 to 44 years, people with bachelors' degree and above, people working for government agencies or institutions, people with unmarried status, and people with an average income of < 2,000 Yuan was longer than that of other respective groups (p < 0.01). In contrast, the daily ST of people with hypertension or with patients with osteoporosis or osteopenia was less than that of normal people (p < 0.01). Additionally, 69.4% of participants generally had a low level of PA (LPA). Compared with those living in northern Zhejiang, people living in southern Zhejiang who were aged 18-44 years, had bachelor's degree or above, were farmers, and had household incomes below 10,000 Yuan per month were more likely to engage in LPA compared to people > 60 years, with high school or technical education levels or with junior college degrees, working in government agencies and institutions, and with household income above 10,000 Yuan per month (p < 0.05). Furthermore, there was no correlation between ST and PA levels. Conclusion: Most rural residents in the Zhejiang Province of eastern China had longer daily ST and a LPA. This was predominant in men, young people, highly educated people, unmarried people, and middle to high-income people. Health education programs should be targeted toward specific population groups to decrease the ST and increase PA.

Prevalence and Correlates of Insufficient Physical Activity Among Adults Aged 18-69 Years in India: Findings From the National Noncommunicable Disease Monitoring Survey.

BACKGROUND: Sufficient physical activity (PA) significantly contributes to the prevention and control of noncommunicable diseases. This study aims to determine the prevalence of insufficient PA and associated sociodemographic and lifestyle factors among adults aged 18-69 years in India. METHODS: A national population-based, cross-sectional survey was conducted during 2017-2018 among 12,000 adults that adapted globally standard data collection tools. The data were weighted and analyzed using complex samples analysis. Logistic regression analysis was performed to identify the sociodemographic and lifestyle factors associated with insufficient PA. RESULTS: Age standardized prevalence of insufficient PA among adults in India was 41.4%. A higher proportion of women (52.4%) and urban adults (51.7%) were not doing sufficient PA. Men (118.8 min) spent more time in PA per day than women (55.3 min). Higher odds of insufficient PA were significantly associated with unemployment (adjusted odds ratio [aOR] = 6.45), highest wealth quintile (aOR = 1.86), presence of central obesity (aOR = 1.24), and raised blood pressure (aOR = 1.22). CONCLUSION: This study provides the baseline prevalence of insufficient PA to monitor the set PA targets for India by 2025. The identified associated factors can guide policy makers to plan tailored interventions targeting high-risk groups and a multisectoral approach to promote PA.

Single versus double plating for bicondylar tibia plateau fractures: Comparison of range of motion, muscle strength, clinical outcomes and accelerometer-measured physical activity levels.

BACKGROUND: Optimal treatment of bicondylar plateau fractures is still a matter of debate. Accelerometer-measured physical activity levels may help us to obtain objective information regarding the quality of life of patients. The aim of this study was to compare the physical activity levels, objective and subjective functional results and stabilities of fixations of patients with treated bicondylar plateau fractures. METHODS: In this cross-sectional study of 23 patients, accelerometer-measured physical activity levels, daily energy consumption and measurements of knee joint range of motion (ROM) and muscle strength were measured. While Knee Injury and Osteoarthritis Outcome Score (KOOS) was used as a patient-reported outcome measurement, Rasmussen Radiological Score was used for radiological evaluation. RESULTS: There was no significant difference between the groups in terms of physical activity levels and daily energy consumption (P = 0.667). While Total KOOS, Symptom and Stiffness and Sports Activities scores were higher in patients with a single plate (P = 0.034, P = 0.003 and P = 0.014, respectively), knee flexion and extension ROM and flexor and extensor muscle strength were similar between groups (P = 0.405, P = 0.095, P = 0.982 and P = 0.988, respectively). CONCLUSIONS: While patient-reported outcome measurements were better with single plating, there was no difference between the groups in terms of physical activity levels, ROM, muscle strength and radiological results. Although it should be kept in mind that the choice of the primary surgeon, the condition of the soft tissue and the fracture geometry are also effective in the decision-making process, single plating seems to be a valid surgical option in the treatment of bicondylar plateau fractures.

Effects of Physical Activity and Circadian Rhythm Differences on the Mental Health of College Students in Schools Closed by COVID-19.

Purpose: Since the prolonged sequestration management that was implemented in order to achieve lower infection and mortality rates, there has been a surge in depression worldwide. The correlation between the physical activity level and the detection rate of a depressed mood in college students should be of wide concern. A large number of studies have focused on the association between physical activity levels and a negative mood, but circadian rhythm differences seem to be strongly associated with both physical activity levels and mental illness. Therefore, this paper will examine the correlation between physical activity levels, circadian rhythm differences, and mental health levels in college students. METHODS: Data were collected through a web-based cross-sectional survey. In June and December 2022, questionnaires were administered to college students from three universities in Anhui, China. In addition to socio-demographic information, measures included the International Physical Activity Questionnaire-Short Form (IPAQ-SF), Morning and Evening Questionnaire-5 Items (MEQ-5), and Symptom Check List90 (SCL-90) scales. Correlation analysis was used to understand the relationship between physical activity and circadian rhythm differences in the three aspects of college student's mental health. RESULTS: The analysis of the data led to the conclusion that 28.4% of the 1241 college students in this survey had psychological disorders. The physical activity level of male students was higher than that of female students, but the risk of having depressive tendencies was higher in female students than in male students. There was a significant negative correlation between the physical activity level and scl-90 scores (p < 0.01), which indicates that higher physical activity levels are associated with higher mental health. Circadian rhythm differences and scl-90 scores were significantly positively correlated among college students (p < 0.01), and night-type people had a higher risk of mental illness than intermediate-type and early-morning-type people. CONCLUSIONS: During the period of closed administration due to COVID-19, school college students experienced large and high levels of negative emotional phenomena due to reduced physical activity and public health emergencies. This study showed significant correlations between both physical activity levels and circadian rhythmicity differences and the degree of mental health of college students.

Independent and combined influences of physical activity, screen time, and sleep quality on adiposity indicators in Indian adolescents.

BACKGROUND: Inadequate physical activity (PA), excess screen time (ST), and sub-optimal sleep quality tend to co-occur during adolescence. Yet, little is known about the associations of these behaviors as a cluster with adiposity indicators in Indian adolescents. This study aimed to evaluate the independent and combined influences of PA, ST, and sleep quality on body mass index (BMI) and waist to height ratio (WHtR) in 10-15 years old adolescents in Mumbai, India. A secondary aim was to explore if these influences vary between sexes. METHODS: Cross-sectional study. Adolescents (n = 772, mean age 13.2 (1.4) years) reported frequency and duration of moderate to vigorous PA (MVPA) and time spent using screens on a previously validated instrument. Sleep quality was estimated using the Pittsburg Sleep Quality Index (PSQI). Weight, height, and waist circumference were measured. Mixed effect logistic regression analyses were performed to explore associations between adiposity indicators (BMI z scores > +1SD and WHtR > 0.5) and unhealthy behaviors (PA < 60 min/d, ST > 120 min/d and PSQI scores > 5), stratified by sex. RESULTS: The combined prevalence of overweight and obesity was 38.3%. Overall, 62.0 and 85.0% reported MVPA< 60 min/d and ST > 120 min/d respectively. Girls reported higher ST (218.21 (69.01) min/d) as compared to boys (165.3 (101.22) min/d, p < 0.001). Clustering of low PA and excess ST was observed in 69.2% and of all three unhealthy behaviors in 18.8%. Among girls, MVPA < 60 min/d (OR = 1.78, 95% CI 1.54-1.92, p < 0.001) and PSQI scores > 5 (OR = 2.01, 95% CI 1.78-2.25, p < 0.001) predicted increased BMI. The odds of overweight/obesity were 2.10 times higher in boys reporting low PA and 4.13 times higher in those with low PA+ ST > 120 min/d. Clustering of all three unhealthy behaviors increased prevalence of obesity in both sexes. CONCLUSIONS: The results indicated a co-existence of multiple unhealthy lifestyle factors of obesity and that clustering of these behaviors can further aggravate obesity risk as compared to their independent effects. Integrated interventions that leverage the cumulative benefits of being active, less sedentary and sufficient sleep are warranted to facilitate greater improvements in obesity risk behaviors.

Longitudinal Perspectives on Children's Physical Activity Patterns: "Do Physical Education-Related Factors Matter?"

BACKGROUND: This study examined longitudinal associations of motor competence (MC) and physical activity (PA) enjoyment with moderate to vigorous PA and sedentary behavior among boys and girls aged 10-12 years old. In addition, this study explored the predictive strength of satisfaction of basic psychological needs in physical education (PE) and PA enjoyment. METHODS: At 3 time points (baseline, +1 y, and +2 y), PA levels, MC, PA enjoyment, satisfaction of basic psychological needs in PE and height and weight of 371 children were measured. Data were analyzed using repeated-measures linear mixed model analyses stratified for gender and adjusted for relevant covariates. RESULTS: Sedentary behavior decreased over time and was significantly predicted by PA enjoyment in boys and by PA enjoyment and MC in girls. Boys' moderate to vigorous PA decreased over time and was predicted by MC, whereas girls' moderate to vigorous PA remained low, yet stable over time and was predicted by PA enjoyment and MC. Furthermore, children's need for competence and teacher relatedness (girls only) during PE significantly predicted PA enjoyment. CONCLUSIONS: Children need sufficient and well-designed opportunities to improve their MC and PA enjoyment. PE may be pivotal in advancing PA enjoyment, indicating that PE could have more beneficial effects on PA levels in children, especially in girls.
