Leisure-time physical activity is associated with depressive symptoms in cancer patients: Data from the NHANES 2007–2018

BackgroundCancer patients have a higher risk of depression and are associated with severe adverse prognosis. The relationship between leisure-time physical activity (LTPA) and depressive symptoms in cancer patients is currently unclear. Therefore, our study mainly explores the potential association between LTPA and the weekly cumulative time of LTPA with depressive symptoms in cancer patients. MethodsWe included and analyzed 3368 cancer patients (aged >20 years) from the National Health and Nutrition Examination Survey (NHANES) of the United States from 1999 to 2018. The LTPA score was evaluated through a self-report questionnaire, while depressive symptoms were evaluated through the Health Questionnaire-9 (PHQ-9). Multiple logistic regression analysis was used to explore the relationship between LTPA duration and the occurrence of cancer-related depressiive symptoms. Linear correlation was studied using the restricted cubic spline method. ResultsAccording to a fully adjusted multivariate logistic regression model with confounding variables, the odds ratio (OR) between LTPA and depressive symptoms in cancer patients in this study was 0.59 (95 % confidence interval = 0.39, 0.92; P = 0.02). When the LTPA level was ≥300 min/week, the incidence of depressive symptoms was reduced by 59 % (OR = 0.41, 95 % CI = 0.21, 0.83). In addition, the cubic spline method was used to obtain a linear negative correlation between LTPA duration and tumor depressive symptoms. ConclusionLTPA was negatively correlated with cancer-related depressive symptoms, and the cumulative time of LTPA/week was linearly correlated with depressive symptoms. The slope of the benefit curve changed significantly when the cumulative time of LTPA reached 600 min per week, suggesting that appropriately increasing LTPA had significant benefits on mental health of cancer patients.

Longitudinal leisure-time physical activity profiles throughout adulthood and related characteristics: a 36-year follow-up study of the older Finnish Twin Cohort

BackgroundPersonalized interventions aiming to increase physical activity in individuals are effective. However, from a public health perspective, it would be important to stimulate physical activity in larger groups of people who share the vulnerability to be physically inactive throughout adulthood. To find these high-risk groups, we identified 36-year leisure-time physical activity profiles from young adulthood to late midlife in females and males. Moreover, we uncovered which anthropometric-, demographic-, lifestyle-, and health-related characteristics were associated with these physical activity profiles.MethodsWe included 2,778 females and 1,938 males from the population-based older Finnish Twin Cohort Study, who responded to health and behavior surveys at the mean ages of 24, 30, 40 and 60. Latent profile analysis was used to identify longitudinal leisure-time physical activity profiles.ResultsWe found five longitudinal leisure-time physical activity profiles for both females and males. Females’ profiles were: 1) Low increasing moderate (29%), 2) Moderate stable (23%), 3) Very low increasing low (20%), 4) Low stable (20%) and 5) High increasing high (9%). Males’ profiles were: 1) Low increasing moderate (29%), 2) Low stable very low (26%), 3) Moderate decreasing low (21%), 4) High fluctuating high (17%) and 5) Very low stable (8%). In both females and males, lower leisure-time physical activity profiles were associated with lower education, higher body mass index, smoking, poorer perceived health, higher sedentary time, high blood pressure, and a higher risk for type 2 diabetes. Furthermore, lower leisure-time physical activity was linked to a higher risk of depression in females.ConclusionsWe found several longitudinal leisure-time physical activity profiles with unique changes in both sexes. Fewer profiles in females than in males remained or became low physically active during the 36-year follow-up. We observed that lower education, higher body mass index, and more smoking already in young adulthood were associated with low leisure-time physical activity profiles. However, the fact that several longitudinal profiles demonstrated a change in their physical activity behavior over time implies the potential for public health interventions to improve leisure-time physical activity levels.

P161 Self-reported barriers to exercise from a national United Kingdom systemic lupus erythematosus cohort

Abstract Background/Aims Patients with systemic lupus erythematosus (SLE) are more inactive than the general population. Regular physical activity (PA) positively impacts many health parameters, including cardiovascular health. To better understand patient barriers to leisure time PA we conducted a national survey of patients with SLE in the UK. Methods An online survey was disseminated via LUPUS UK social media platforms between 5/05/2023 and 28/10/2023. Participants self-reported demographic data including postcodes. Indices of Multiple Deprivation (IMD) were used to define socioeconomic deprivation and were split into quantiles, where quartile 5 represents participants living in 20% least deprived areas in England. Categorical and continuous data were analysed using Fisher’s exact test and Mann-Whitney U test respectively. Results There were 249 individual responses. Table 1 describes the cohort demographics alongside response data. On a 0-10 scale (very unsatisfied to very satisfied), 171/244 (70%) of participants rated their satisfaction with their amounts of leisure time PA as ≤ 4. The most commonly reported barriers to PA were fatigue (221/249, 88.8%), pain (155/249, 62.2%) and lupus-related symptoms/flares (145/249, 58.2%). Dislike of exercise was reported by < 10% of cohort (22/249, 8.8%). When asked to identify the primary barrier to PA, 119/244 (48.8%) reported fatigue. Lack of motivation (40/244, 16.4%) and knowledge about exercise (18/244, 7.4%) were other predominant barriers. Concern around injury differed between ethnic groups (p = 0.016). Other barriers did not differ by sex, ethnic group or socioeconomic deprivation. Participants reporting lack of time were younger with a median age of 45 (35-53) versus 54 (43-63) years, p = <0.001. Patients reporting fatigue, pain and self-consciousness had higher BMI in kg/m2 (27.7 [23.6-32.3] vs 23.4 [20.8-28.2]; 28.7 [23.8-33.1] vs 25.4 [22.6-28.8]; 31.4 [27.9-38.4] vs 25.8 [23.1-30.2]), p = <0.001. Lupus-related symptoms/flares and concern that PA may worsen lupus were reported by participants with a shorter disease duration in years (8 [3-17] vs 12 [4.5-24] p = 0.002, and 7 [2-15] vs 10 [4.5-23] p = <0.001 respectively). Conclusion 70% of patients were dissatisfied with their level of leisure time PA. Fatigue and pain were the most commonly reported barriers to PA. Reported barriers differ between patients highlighting the need for personalised exercise programmes for patients with SLE. Disclosure A. Baranskaya: None. A.J. Wadley: None. J. Reynolds: None.

NHANES-based analysis of the correlation between leisure-time physical activity, serum cotinine levels and periodontitis risk

ObjectiveTo investigate the association of leisure-time physical activity and serum cotinine levels with the risk of periodontitis in the general population and to further analyze the interaction between leisure-time physical activity and serum cotinine levels on the risk of periodontitis.MethodsThis was a cross-sectional study, extracting data from 9605 (56.19%) participants in the National Health and Nutrition Examination Survey (NHANES) database from 2009 to 2014, and analyzing the relationship and interaction effects of serum cotinine level, leisure time physical activity, and risk of periodontitis by weighted univariate logistic modeling; Effect sizes were determined using ratio of ratios (OR), 95% confidence intervals (95% CI).Results5,397 (56.19%) of 9,605 participants had periodontitis; an increased risk of periodontitis was found in those in the leisure time physical activity intensity < 750 MET × min/week group (OR = 1.44, 95% CI: 1.17–1.78). Serum cotinine levels ≥ 0.05 ng/ml were associated with an increased risk of periodontitis (OR = 1.99, 95% CI: 1.69–2.33). The group with low leisure physical activity and serum cotinine levels ≥ 0.05 ng/ml had an increased risk of periodontitis compared to the group with high leisure physical activity and serum cotinine levels < 0.05 ng/ml (OR = 2.48, 95% CI: 1.88–3.27). Interaction metrics RERI = 0.90 (95% CI: 0.44–1.36) and API = 0.36 (95% CI: 0.18–0.55); CI for SI = 2.55 (95% CI: 1.03–6.28). for API 0.36.ConclusionLeisure time physical activity intensity interacted with smoking exposure on periodontitis risk and may provide the general population with the opportunity to Increasing leisure-time physical activity and smoking cessation may provide recommendations for the general population.

Work-, lifestyle-, and health-related factors among women and men working in the emergency medical services

Objectives. This study aimed to describe work-, lifestyle-, and health-related factors among ambulance personnel, and to analyse differences between women and men. Methods. The cross-sectional study (N = 106) included self-reported and objective measures of work, lifestyle, and health in 10 Swedish ambulance stations. The data collection comprised clinical health examination, blood samples, tests of physical capacity, and questionnaires. Results. A high proportion of the ambulance personnel reported heavy lifting, risk of accidents, threats and violence at work. A low level of smoking and alcohol use, and a high level of leisure-time physical activity were reported. The ambulance personnel had, on average, good self-rated health, high work ability and high physical capacity. However, the results also showed high proportions with risk factors for cardiovascular disease (CVD), e.g., high blood pressure, and high levels of blood lipids. More women than men reported high work demands. Furthermore, women performed better in tests of physical capacity and had a lower level of CVD risk factors. Conclusions. Exposure to work-related factors that might affect health was common among ambulance personnel. Lifestyle- and health-related factors were somewhat contradictory, with a low proportion reporting lifestyle-related risk factors, but a high proportion having risk factors for CVD.

Association Between Leisure-Time Physical Activity and Occupation Activity Level, National Health Interview Survey-United States, 2020.

Physical activity for any purpose counts toward meeting Physical Activity Guidelines (PAG). However, national surveillance systems traditionally focus on leisure-time physical activity. There is an incomplete understanding of the association between meeting PAG in leisure time and occupation activity level among US workers. We used cross-sectional 2020 National Health Interview Survey data to examine US adults aged 18-64years who worked the week before the survey (n = 14,814). We estimated the proportion meeting aerobic and muscle-strengthening PAG in leisure time by occupation activity level (low, intermediate, and high). Using logistic regression, we examined the association between meeting PAG in leisure time and occupation activity level, adjusted for sociodemographic characteristics and stratified by hours worked. We compared the sociodemographic characteristics of adults working ≥40hours (the previous week) in high-activity occupations to those in low- or intermediate-activity occupations. Adults working in high-activity occupations were less likely to meet PAG in leisure time (26.1% [24.3-28.1]) versus those in low-activity (30.6% [29.1-32.2], P < .01) or intermediate-activity (32.4% [30.8-34.2]) occupations. In stratified, adjusted models, adults working ≥40hours in low- and intermediate-activity occupations were 13% and 20%, respectively, more likely to meet PAG in leisure time versus those in high-activity occupations. Among those working ≥40hours, adults in high-activity occupations were more likelyto be Hispanic or Latino, male, younger, and have a high school education or lower compared with those in less active occupations. Traditional surveillance may underestimate meeting PAG among people working in high-activity occupations, potentially disproportionately affecting certain groups.

Joint effect of physical activity and sedentary behavior with the female urinary incontinence: an analysis of NHANES 2011-2016.

Our study aimed to assess the independent and joint effects of leisure-time physical activity and sedentary behavior with urinary incontinence (UI). Data were obtained from the National Health and Nutrition Examination Survey 2011-2016. The primary endpoint was the risk of different subtypes of UI, including stress UI, urgency UI, and mixed UI. The primary exposures were leisure-time physical activity and sedentary behavior. Sedentary behavior was assessed by screen time. Weighted univariate and multivariate logistic regression models were used to observe the independent and joint relationship of leisure-time physical activity and sedentary behavior with UI risk (including stress UI, urgency UI, and mixed UI). In total, 6,927 female participants were included in this analysis. 3,377 females did not have UI, 1,534 had stress UI, 836 had urgency UI, and 1,180 had mixed UI. Screen time with ≥5h/day was associated with increased odds of urgency UI [odds ratio (OR) =1.31, 95% confidence intervals (CI): 1.06-1.61], which indicated the relationship of sedentary behavior and urgency UI. Engaging in leisure-time physical activity with of ≥750 metabolic equivalent (MET)·min/week was found to be significantly associated with reduced likelihood of mixed UI (OR=0.68, 95%CI: 0.55-0.85). Additionally, the interaction term of leisure-time physical activity<750 MET· min/week and screen time≥5h/day was observed to be linked with increased odds of urgency and mixed UI. Participants experiencing a lower level of leisure-time physical activity and a higher level of sedentary behavior together might enhance the urgency and mixed UI risk.

Risk of stroke with different levels of leisure-time physical activity: a systematic review and meta-analysis of prospective cohort studies

Is physical activity associated with a higher degree of wisdom? Cross-sectional study with high school students

The aim of this study was to verify the association between the degree of wisdom and the level of leisure-time physical activity (PA) of students from a federal public school in southern Brazil. Observational cross-sectional study with 462 young people of both sexes between 15 and 18 years old. Data collection was performed using a self-administered questionnaire on the REDCap platform. The independent variable was the “level of leisure PA” (inactive, insufficiently active, and physically active) and the outcome was the “degree of wisdom” evaluated through a validated questionnaire (SD-WISE7). There was a linear trend towards an increase in the wisdom score according to the level of PA. This trend and significant association continued in the adjusted analysis, with active students averaging 1.84 points more in the wisdom score compared to inactive students. In conclusion, the wisest young people are also the most physically active young people. In view of the potential beneficial effects, current studies may consider wisdom as a possible mediator of PA with health outcomes.

The association between work-related activities and leisure-time physical activity among Latinos

ABSTRACT Objectives Latinos engage in high levels of occupational physical activity, yet low levels of leisure-time physical activity. Limited research has examined specific work-based activities that may contribute to leisure-time physical activity for meeting current physical activity recommendations among Latinos. The purpose of our study was to examine associations between frequency of work-related exertion and standing/walking with meeting the aerobic and muscle-strengthening physical activity guidelines among Latinos and whether associations varied by nativity. Design We used cross-sectional 2015 National Health Interview Survey data on Latinos ≥18 years of age (n = 3162). Logistic regression models were used to estimate associations between the frequency of work-related activities with meeting the aerobic and muscle-strengthening physical activity guidelines. Models were adjusted for age, sex, education, Latino subpopulation, shift work, and nativity. We also examined whether associations varied by nativity. Results In adjusted models, compared with those never engaging in exertion at work, participants always exerting themselves were significantly less likely to meet the aerobic activity guideline (Odds Ratio [OR]: 0.66, 95% Confidence Interval [CI]: 0.51–0.87). Compared with those never standing/walking at work, participants seldom standing/walking were also less likely to meet the aerobic activity guideline (OR: 0.57, 95% CI: 0.34, 0.95). Models were adjusted for age, sex, education, Latino subpopulation, shift work, and nativity. When stratified by nativity, the patterns in the strength of the associations were similar, while differences were observed in the associations of work-related activities with meeting guidelines. Conclusion Our findings suggest that engaging in higher frequency of exertion and standing/walking at work are associated with being less likely to meet the aerobic physical activity guideline during leisure time among Latinos, with variation observed in meeting guidelines by nativity. Insight into physical activities performed at work could inform efforts aimed at promoting recommended levels of physical activity among Latinos.

Occupational Sitting Time, Leisure Physical Activity, and All-Cause and Cardiovascular Disease Mortality

For the first time, the 2020 World Health Organization guidelines on physical activity recommended reducing sedentary behaviors owing to their health consequences. Less is known on the specific association of prolonged occupational sitting with health, especially in the context of low physical activity engagement. To quantify health risks associated with prolonged occupational sitting and to determine whether there is a certain threshold of physical activity that may attenuate it. This prospective cohort study included participants in a health surveillance program in Taiwan who were followed-up between 1996 and 2017. Data on occupational sitting, leisure-time physical activity (LTPA) habits, lifestyle, and metabolic parameters were collected. Data analysis was performed in December 2020. The all-cause and cardiovascular disease (CVD) mortality associated with 3 occupational sitting volumes (mostly sitting, alternating sitting and nonsitting, and mostly nonsitting) were analyzed applying multivariable Cox regression models to calculate the hazard ratios (HRs) for all participants and by subgroups, including 5 LTPA levels and a personal activity intelligence (PAI)-oriented metric. Deaths occurring within the initial 2 years of follow-up were excluded to prevent reverse causality. The total cohort included 481 688 participants (mean [SD] age, 39.3 [12.8] years; 256 077 women [53.2%]). The study recorded 26 257 deaths during a mean (SD) follow-up period of 12.85 (5.67) years. After adjusting for sex, age, education, smoking, drinking, and body mass index, individuals who mostly sat at work had a 16% higher all-cause mortality risk (HR, 1.16; 95% CI, 1.11-1.20) and a 34% increased mortality risk from CVD (HR, 1.34; 95% CI, 1.22-1.46) compared with those who were mostly nonsitting at work. Individuals alternating sitting and nonsitting at work did not experience increased risk of all-cause mortality compared with individuals mostly nonsitting at work (HR, 1.01; 95% CI, 0.97-1.05). For individuals mostly sitting at work and engaging in low (15-29 minutes per day) or no (<15 minutes per day) LTPA, an increase in LTPA by 15 and 30 minutes per day, respectively, was associated with a reduction in mortality to a level similar to that of inactive individuals who mostly do not sit at work. In addition, individuals with a PAI score exceeding 100 experienced a notable reduction in the elevated mortality risk associated with prolonged occupational sitting. As part of modern lifestyles, prolonged occupational sitting is considered normal and has not received due attention, even though its deleterious effect on health outcomes has been demonstrated. In this study, alternating between sitting and nonsitting at work, as well as an extra 15 to 30 minutes per day of LTPA or achieving a PAI score greater than 100, attenuated the harms of prolonged occupational sitting. Emphasizing the associated harms and suggesting workplace system changes may help society to denormalize this common behavior, similar to the process of denormalizing smoking.

Trends in obesity, leisure-time physical activity, and sedentary behavior in Korean adults: Korea national health and nutritional examinations survey from 2014 to 2021.

This study aimed to investigate trends in obesity by dividing it based on body mass index (BMI) and waist circumference indicators, sedentary behavior, and leisure-time physical activity (LTPA) in Korean adults from 2014 to 2021. This study also aimed to determine the adherence rate of people with obesity to physical activity. Data from the Korea National Health and Nutritional Examination Survey (KNHANES) from 2014 to 2021 were used. A total of 42,676 participants 19 years or older were included in the final analysis. Sociodemographic characteristics, anthropometric measurements, and physical activity levels were recorded. Physical activity levels were assessed using the Global Physical Activity Questionnaire, a self-reported questionnaire. Multivariable logistic regression analysis adjusted for covariates was used to investigate the prevalence of obesity and sitting time or adherence to meeting the physical activity guidelines for each survey year. This study included 42,676 adults. The weighted prevalence of obesity in all ages significantly increased from 30.8% (29.1%-32.5%) in 2014 to 34.5% (32.9%-36.2%) in 2017 and 37.3% (35.5%-39.1%) in 2021 (p for trend < 0.004). The weighted adherence rate to LTPA ranged from 25.5% (95% confidence interval [CI], 23.7%-27.2%) in 2014 to 20.5% (95% CI, 18.7%-22.2%) in 2021(p for trend < 0.001). The weighted prevalence of sitting time for 8 h/day or more significantly increased from 46.7% (44.4%-49.0%) in 2014 to 56.2% (54.4%-58.0%) in 2017 and 63% (60.7%-65.3%) in 2021 (p for trend < 0.001). According to this study, the LTPA level among women with obesity was significantly low. From 2014 to 2021, obesity and sedentary behavior significantly increased and adherence to LTPA decreased among Korean adults. Given these concerning trends, comprehensive interventions are needed at the national level to encourage healthy lifestyle behaviors.

Sex disparities in physical activity domains and hypertension prevalence

BackgroundThis study aimed to examine the associations of leisure time physical activity (LTPA) and occupational physical activity (OPA) with the prevalence of hypertension, while exploring the sex disparities in these associations.MethodsA cross-sectional study was conducted using data from the Korea National Health and Nutrition Examination Survey between 2014 and 2019 (n = 26,534). Hypertension was defined as the use of antihypertensive drugs or systolic and diastolic blood pressure ≥ 140/90 mm Hg. Self-reported physical activity (PA), assessed by the global PA questionnaire, was categorized into three domains: total PA, LTPA and OPA. Each PA domain was classified based on METs-min/wk and intensity.ResultsIn a multivariable adjusted model, the odds ratio (OR) with 95% confidence intervals (CIs) for the prevalence of hypertension in the active versus inactive group, based on METs, was 0.92 (95% CI 0.85–0.99) for total PA, 0.90 (95% CI 0.83–0.98) for LTPA and 1.21 (95% CI 1.05–1.38) for OPA. Compared to the inactive group, moderate to vigorous intensity was associated with a lower odds of hypertension for total PA and LTPA (total PA: OR 0.95, 95% CI 0.89-1.00 and LTPA: OR 0.92, 95% CI 0.86–0.98), but a higher odd for OPA (OR 1.17, 95% CI 1.05–1.30). Subgroup analyses showed significant evidence of effect modification by sex on the associations of total PA and LTPA (METs and intensity) with hypertension prevalence (p-values for interaction < 0.01); the associations were generally stronger for women. OPA was associated with a higher prevalence of hypertension in women, but not in men (p-value for interaction > 0.05).ConclusionsHigher levels of total PA and LTPA were associated with lower prevalence of hypertension in both men and women, with slightly stronger associations for women. However, higher OPA was associated with a higher prevalence of hypertension in women. These findings support the PA health paradox hypothesis and highlight the sex disparities in the association between OPA and hypertension prevalence.

Leisure-Time Physical Activity in a Southern Brazilian City (2004-2021): Applying an Equity Lens to Time-Trend Analyses.

This study aimed to verify leisure-time physical activity trends over 15years and monitor inequalities according to gender, self-reported skin color, and socioeconomic position in a Southern Brazilian city. A secondary aim is to evaluate intersectionalities in physical activity. Trend analysis using 3 population-based surveys carried out in 2004, 2010, and 2021. Main outcome assessed was the prevalence of physical activity according to recommendations (150min/wk). Inequalities dimensions measured were sex, self-reported skin color, and wealth. Intersectionalities were evaluated using Jeopardy index combining all inequality dimensions. Trend analysis was performed using least-squares weighted regression. We included data from 3090, 2656, and 5696 adults in 2004, 2010, and 2021, respectively. Prevalence of physical activity remains stable around 25% in the 3years. In the 3 periods evaluated, men presented a prevalence in average 10 percentage points higher than women (SII2004 = -11.1 [95% confidenceinterval, CI, -14.4 to -7.8], SII2021 = -10.7 [95% CI, -13.7 to -7.7]). Skin color inequalities did not present a clear pattern. Richest individuals, in general presented a prevalence of leisure-time physical activity level 20pp higher than poorest ones (SII2004 = 20.5 [95% CI, 13.7 to 27.4]; SII2021 = 16.7 [95% CI, 11.3 to 22.0]). Inequalities were widely marked, comparing the most privileged group (represented by men, the wealthiest, and White) and the most socially vulnerable group (represented by women, the poorest, and Black/Brown). The Slope Index of Inequality for intersectionalities was -24.5 (95% CI, -31.1 to -17.9) in 2004 and -18.8 in 2021 (95% CI, -24.2 to -13.4). Our analysis shows that women, Black/Brown, and poor present lower leisure-time physical activity level. This group is often neglected regarding other health and social outcomes.

Prevalence of Perceived Barriers to Physical Activity Among Pre- and Post-Metabolic and Bariatric Surgery Patients: A Cross-Sectional Study.

This study aims to describe and compare the prevalence of perceived barriers to physical activity (PBPA) in pre- and post-metabolic and bariatric surgery (MBS) patients and assess the association of these barriers with their physical activity levels. A cross-sectional study included pre-operative (n = 63) and post-operative (n = 119) groups. Sociodemographic characteristics, leisure-time physical activity levels, and PBPA data were collected. Descriptive statistics, chi-square, and Fisher's exact tests, and binomial logistic regression analyses were used for comparisons and associations. Compared to the pre-operative group, the post-operative group had a lower prevalence of barriers in the physical domain (p = 0.036) and the behavioral domain (p = 0.004). However, there were no significant differences in the environmental (p = 0.531) or social (p = 0.597) domains. Pre-MBS patients were more likely to be physically inactive when perceiving barriers in the environmental (p = 0.048) and behavioral (p = 0.048) domains. In contrast, post-surgical patients were more likely to be physically inactive when perceiving barriers in the environmental (p = 0.027), social (p = 0.020), and behavioral (p = 0.037) domains. The results show that individuals who underwent metabolic and bariatric surgery have a lower prevalence of behavioral and physical PBPA compared to those awaiting the procedure. The perception of barriers to physical activity in the environmental and behavioral domains increases the likelihood of physical inactivity in both pre- and post-MBS patients, while in the social domain, it was only associated with physical activity in post-MBS patients.

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.

Prediction of Cardiorespiratory Fitness Level of Young Healthy Women Using Non-Exercise Variables

Cardiorespiratory fitness (CRF) is considered an important indicator of health in children and adults. The main contribution of this paper is an analysis of cardiorespiratory fitness predictive models among a population of healthy and young women, using the non-exercise variables. The study was conducted on a group of 154 healthy women (aged 20.3 ± 1.2) from selected academic centers in Poland. The VO2max was measured using a Cosmed K4b2 portable analyzer during a 20 m shuttle test. In addition, selected anthropomotor parameters including body composition components were measured for each subject. The participants’ leisure-time physical activity was assessed using the Minnesota Leisure-Time Physical Activity Questionnaire. The Ridge regression was the most accurate model for estimating VO2max from anthropometric parameters. The most accurate model based on the level of leisure-time physical activity was calculated using stepwise regression for which the prediction error was at the level of 6.68 (mL·kg−1·min−1). The best model calculated from all non-exercise variables (age, anthropometric parameters, and leisure-time physical activity) had only two predictors: waist circumference and total physical activity, and had a prediction error equal to 6.20 (mL·kg−1·min−1).

International Pooled Analysis of Leisure-Time Physical Activity and Premenopausal Breast Cancer in Women From 19 Cohorts.

There is strong evidence that leisure-time physical activity is protective against postmenopausal breast cancer risk but the association with premenopausal breast cancer is less clear. The purpose of this study was to examine the association of physical activity with the risk of developing premenopausal breast cancer. We pooled individual-level data on self-reported leisure-time physical activity across 19 cohort studies comprising 547,601 premenopausal women, with 10,231 incident cases of breast cancer. Multivariable Cox regression was used to estimate hazard ratios (HRs) and 95% CIs for associations of leisure-time physical activity with breast cancer incidence. HRs for high versus low levels of activity were based on a comparison of risk at the 90th versus 10th percentiles of activity. We assessed the linearity of the relationship and examined subtype-specific associations and effect modification across strata of breast cancer risk factors, including adiposity. Over a median 11.5 years of follow-up (IQR, 8.0-16.1 years), high versus low levels of leisure-time physical activity were associated with a 6% (HR, 0.94 [95% CI, 0.89 to 0.99]) and a 10% (HR, 0.90 [95% CI, 0.85 to 0.95]) reduction in breast cancer risk, before and after adjustment for BMI, respectively. Tests of nonlinearity suggested an approximately linear relationship (Pnonlinearity = .94). The inverse association was particularly strong for human epidermal growth factor receptor 2-enriched breast cancer (HR, 0.57 [95% CI, 0.39 to 0.84]; Phet = .07). Associations did not vary significantly across strata of breast cancer risk factors, including subgroups of adiposity. This large, pooled analysis of cohort studies adds to evidence that engagement in higher levels of leisure-time physical activity may lead to reduced premenopausal breast cancer risk.

The relationship between physical activity and mental health: Is more always better?

The current study was designed to examine the relationship between physical activity and mental health. We investigated whether individuals who perceive themselves as physically inactive, recreationists, or active athletes differ in positive (positive affect, subjective well-being, unconditional self-acceptance) and negative mental health outcomes (depression, anxiety, stress, negative affect, conditional self-acceptance). Furthermore, we investigated whether the total level of leisure-time physical activity predicted different mental health indicators. Analysis revealed that physically active respondents (recreationists and active athletes) seem to have better overall mental health status than physically inactive ones. Precisely, physically inactive individuals scored higher on all measures of negative mental health indicators, and lower on all measures of positive mental health indicators, compared with the participants from the two other groups. At the same time, there were no significant differences in these measures between recreationists and active athletes. Besides, a positive association was found between the weekly frequency of leisure-time activity and only two positive indicators of mental health (positive affect and subjective well-being)of all tested. The obtained results suggest that it is often more relevant for mental health whether someone is physically active or not, in general, than how frequently they exercise.

The role of leisure-time physical activity in maintaining cervical lordosis after anterior cervical fusion and its impact on the motor function in patients with hirayama disease: a retrospective cohort analysis

BackgroundSurgical treatment has been increasingly performed in Hirayama disease (HD) patients to limit excessive neck flexion and restore cervical lordosis. However, postoperative recurrence of cervical lordosis loss may restart the progress of HD. Many studies have demonstrated a relationship between neck muscle strength and cervical lordosis, and it is widely accepted that leisure-time physical activity (LTPA) can increase muscle strength. However, there are few reports about the correlation between LTPA and maintenance of postoperative cervical curvature.ObjectiveTo quantify the cervical lordosis and motor function before and after operation in HD patients and to analyze the impact of postoperative LTPA levels on the changes in these measurements.MethodsC2-7 Cobb were measured in 91 HD patients before, 2–5 days and approximately 2 years after operation. Motor unit number estimation (MUNE) and handgrip strength (HGS) were performed in all patients before and approximately 2 years after operation, and both cross-sectional area and fatty infiltration of posterior cervical muscles were measured in 62 patients. Long-form international Physical Activity Questionnaire and its different domains was administered to all patients at postoperative 2-year assessments.ResultsThe C2-7 Cobb was larger immediately and approximately 2 years after operation than that at preoperative assessment (P < 0.05). The preoperative to postoperative change in C2-7 Cobb was associated with postoperative changes in the symptomatic-side HGS and bilateral MUNE measurements (P < 0.05). Importantly, the patients performing LTPA had greater improvements in C2-7 Cobb from immediate to approximately 2 years after operation and greater C2-7 Cobb at last follow-up than those without LTPA, and postoperative improvements in both symptomatic-side MUNE measurements and symptomatic-side HGS were also greater in the former than in the latter (P < 0.05).ConclusionsPostoperative LTPA has a positive effect on recovery/maintenance of cervical lordosis after operation, which may alleviate the motor unit loss of distal upper limbs in HD patients. Therefore, postoperative LTPA may be beneficial for postoperative rehabilitation or early conservative treatment of HD patients.
