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.

Occupational and leisure-time physical activity and associated factors among shift-working registered nurses: A cross-sectional study

BackgroundLifestyle behaviors, including physical activity, may help to mitigate the chronic disease and mental health consequences of shift work in nurses at the individual level. The physical activity levels of shift-working nurses and factors that predict physical activity in this population are unclear. ObjectiveThe primary aim of this study was to describe work and leisure-time physical activity behaviors in shift-working hospital nurses and determine behavioral, biological, or work-related factors that influence physical activity. DesignObservational; cross-sectional. Setting(s)Acute care hospital system. ParticipantsCurrent registered nurses (N = 112) with a shift work schedule (rotating, mixed, or permanent night shift) MethodsOnline validated questionnaires were used to assess work and leisure physical activity levels (International Physical Activity Questionnaire); Theory of Planned Behavior constructs (attitudes, subjective norms, perceived behavioral control, and intention) related to physical activity; and morningness-eveningness. Work-related characteristics were also assessed. Structural equation models were examined for the Theory of Planned Behavior constructs. ResultsShift-working nurses reported 227 (±265) minutes/week of leisure-time and 566 (±868) minutes/week of occupational moderate-to-vigorous physical activity. Attitude (standardized coefficient = 0.63; p < 0.05) was the strongest predictor of physical activity intention, and intention (standardized coefficient = 0.40; p < 0.05) was a significant predictor of leisure-time physical activity behavior. There were no statistically significant differences in physical activity type and amount between those who identified as “morning”, “intermediate”, or “evening” types. Clinical nurse leaders engaged in statistically significantly less leisure-time physical activity than direct care nurses (703 ± 1142 vs. 1202 ± 1372 MET-minutes/week) (p = 0.013). ConclusionsOur findings suggest that on average, shift-working registered nurses report meeting national physical activity guidelines for leisure and occupational physical activity; however, there is considerable interindividual variability. Theory of Planned Behavior constructs, especially attitude and intention, were significantly associated with leisure-time physical activity but not occupational physical activity, emphasizing the importance of targeting them in interventions to increase physical activity levels among shift-working nurses.

The Association between Physical Activity and Intrinsic Capacity in Chinese Older Adults and Its Connection to Primary Care: China Health and Retirement Longitudinal Study (CHARLS)

In 2015, intrinsic capacity (IC) was proposed by the WHO as a new measure for healthy aging. Evidence has shown that physical activity (PA) benefits the physical and mental health of older adults. However, the association between PA and IC among older adults was not well evaluated or reported. This study aims to investigate the association between PA and general and specific IC among Chinese older adults. The study included individuals aged 60 and above from the China Health and Retirement Longitudinal Study in 2015. The IC scores were constructed based on the WHO concept of five domains: psychological capacity, cognition, locomotion, vitality, and sensory abilities. Total PA and leisure PA were measured based on different activity purposes. Linear mixed-effects models and generalized linear mixed-effects models were developed to assess the associations between PA and IC. A total of 3359 participants were included in this study. Older adults who reported some PA were associated with a higher composite IC score, with a mean difference of 0.14 (95% CI: 0.09-0.18, p < 0.001) compared to those who reported no PA. In terms of leisure PA, physically active adults had a higher composite IC score with a mean difference of 0.06 (95% CI: 0.03-0.09, p < 0.001). Older adults with a high level of leisure PA also had a significantly higher composite IC score (diff. in mean = 0.07, 95% CI: 0.01-0.13, p < 0.05) compared to those with low-level leisure PA. In addition, PA was positively and significantly associated with three specific IC domains: locomotion, cognition, and vitality. Improving both general and leisure PA can be an effective way to prevent the decline in IC among older adults, thus reducing the personal and public load of primary healthcare for aging countries such as China.

The effect of different types of physical activity on cognitive reaction time in older adults in China.

Aging is not only reflected in the degeneration of physiological functions but is also embodied in the decline of psychological and cognitive functions. The decline of cognitive function can reduce the quality of life in older adults, and even potentially cause Alzheimer's disease, which may lead to a heavy burden on patients, families, and society. The purpose of this study was to investigate the effects of physical activity (PA) on cognitive reaction time in older adults. A cross-sectional survey design was used in this study. A total of 839 elderly subjects were recruited from Beijing and Shanghai. In total, 792 subjects met the inclusion criteria (age > 60 years, without disability, speech, and hearing impairment), including 384 men (age:67.7 ± 5.7 years) and 408 women (age: 68.2 ± 5.8 years). The PA was assessed by the Physical Activity Scale for the Elderly (PASE). All kinds of PA were divided into three levels: "Low" (< 50% average score), "Moderate" (50-150% average score), and "High" (>150% average score). The reaction time of subjects was measured by the selective reaction tester (Model: CSTF-XF, TFHT, Beijing, China). For leisure-time PA, the results showed that the cognitive reaction time of older adults in the "Low" group (1.11 ± 0.32 s) was significantly longer than that in the "Moderate" group (1.05 ± 0.30 s, p < 0.01) and the "High" group (0.99 ± 0.28 s, p < 0.01). For housework PA, there was no significant difference in the cognitive reaction time among the three groups ("Low": 1.09 ± 0.31 s; "Moderate": 1.07 ± 0.31 s; "High": 1.05 ± 0.28 s, p > 0.05). For work-related PA, the results showed that the cognitive reaction time of older adults in the "Low" group (1.09 ± 0.30 s) was significantly longer than that in the "High" group (0.99 ± 0.28 s) and the "Moderate" group (1.03 ± 0.32 s, p < 0.01). The PA has a positive effect on reducing cognitive reaction time in older adults. It is recommended that older adults maintain a moderate level of leisure PA and work-related PA to delay the decline in cognitive reaction time.

The Influence of Obesity on Nutrition and Physical Activity during COVID-19 Pandemic: A Case-Control Study.

Obesity is one of the important risk factors for a severe course of COVID-19. Maintaining a healthy body weight through diet and physical activity is a reasonable approach to preventing a SARS-CoV-2 infection or in alleviating its course. The goal of the study was to determine the influence of obesity on nutrition and physical activity during the COVID-19 pandemic. A total of 964 respondents, including 227 individuals with a body mass index (BMI) ≥30 kg/m2 were evaluated in this study. In the case of 482 respondents, including 105 individuals (21.8%) with BMI ≥ 30 kg/m2, the data were collected during the pandemic period from 1 June to 31 August 2020. The remaining 482 individuals were the “pre-pandemic” group, selected via propensity score matching (PSM) out of the 723 National Health Program study participants whose data was collected in 2017–2019. The evaluated dietary health factors were quantitatively similar in patients with BMI of either <30 kg/m2 or ≥30 kg/m2 and showed no significant changes during the pandemic. The diets of those who suffered from obesity prior to the pandemic showed the evaluated unhealthy nutritional factors to be less pronounced in comparison with those of individuals with BMI < 30 kg/m2. During the pandemic, the BMI ≥ 30 kg/m2 group showed a significant increase in the overall calorie intake (by 319 kcal; p = 0.001) and an increased consumption of total carbohydrates 299.3 ± 83.8 vs. 252.0 ± 101.5; p = 0.000), sucrose (51.7 ± 30.0 vs. 71.6 ± 49.9; p = 0.000), plant protein (26.3 ± 12.1 vs. 29.3 ± 8.3; p = 0.040), total fat (73.1 ± 42.6 vs. 84.9 ± 29.6; p = 0.011) and saturated fatty acids (29.5 ± 16.4 vs. 34.3 ± 13.9; p = 0.014) in comparison with the pre-pandemic period. The energy and nutritional value of the diets of BMI < 30 kg/m2 individuals did not change between the pre-pandemic and pandemic period. Before the pandemic, the level of leisure physical activity of the BMI ≥ 30 kg/m2 group was significantly lower than of those with BMI < 30 kg/m2. Such differences were not observed in the levels of physical activity at work or school. The pandemic did not alter the amount of physical activity either during leisure time or at work/school in individuals with BMI ≥ 30 kg/m2. However, respondents without obesity exercised significantly less during the pandemic than before. In conclusion, the pandemic altered the diets and levels of physical activity in the Polish population, with dietary changes observed in individuals with BMI ≥ 30 kg/m2 and changes in physical activity observed in those with BMI < 30 kg/m2.

Television Viewing Time and the Risk of Colorectal Cancer Mortality among Japanese Population: The JACC Study.

PurposeSedentary behavior attributes to the increased risk of some cancers and all-cause mortality. The evidence is limited for the association between television (TV) viewing time, a major sedentary behavior, and risk of colorectal cancer death. We aimed to examine this association in Japanese population.Materials and MethodsA prospective cohort study encompassed of 90,834 men and women aged 40–79 years with no prior history of colorectal cancer who completed a self-administered food frequency questionnaire, and provided their TV viewing information. The participants were followed-up from 1988–1990 to the end of 2009. The hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated by the Cox proportional hazard regression for risk of colorectal cancer mortality according to TV viewing time.ResultsDuring the median 19.1-year follow-up period, we documented 749 (385 men and 364 women) colorectal cancer deaths. The multivariable-adjusted HRs for mortality from colorectal cancer were 1.11 (0.88–1.41) for 1.5 to < 3 hr/day, 1.14 (0.91–1.42) for 3 to < 4.5 hr/day and 1.33 (1.02–1.73) for ≥ 4.5 hr/day in comparison to < 1.5 hr/day TV watching; p-trend=0.038, and that for 1-hour increment in TV viewing time was 1.06 (1.01–1.11). Moreover, the multivariable-adjusted HR (95% CI) of colon cancer for 1-hour increment in TV viewing time was 1.07 (1.02–1.13). Age, body mass index, and level of leisure-physical activity did not show significant effect modifications on the observed associations.ConclusionTV viewing time is associated with the increased risk of colorectal cancer mortality among Japanese population, more specifically colon rather than rectal cancer.

Abstract C049: The association between breast cancer and physical activity levels by race in a prospective cohort study

Abstract Background: Although the relationship between physical activity and breast cancer is well established, research demonstrating levels of physical activity and breast cancer association among different racial groups is less definitive. It is perceived by the public that beneficial effects of physical activity depend on the rigorousness of activity performed, and within these levels of physical activity, racial differences are observed. Objectives: The aim of this study is to evaluate levels of physical activity among different racial groups, while stratifying for menopause status, and their relationship to breast cancer. Specifically examining incidence and prevalent breast cancer cases, this study examined potential variation of physical activity in relation to time of cancer diagnosis among different racial groups. Methods: A cohort of 26,387 women in the Arkansas Rural Community Health Study (ARCH) was used to evaluate physical activity and its association with breast cancer among different racial groups. Multiple logistic regression (OR, 95%CI) was used to examine the association between breast cancer and intensity, length, and frequency of physical activity while adjusting for confounding variables, such as age and parity. Demographic and weekly physical activity information was reported at baseline. A Metabolic Equivalent of Task score was derived from the self-reported questionnaire data. Results: A total of 1,455 participants were excluded due to insufficient information regarding breast cancer status, race, and menopausal status, resulting in a sample of 23,980 participants. The analysis consisted of 155 newly diagnosed breast cancer cases after the baseline (incident), 2,330 existing breast cancer cases when entering the study (prevalent), and 21,495 noncancer subjects, of whom 78% identified as European American (EA) and 22% identified as African American (AA). Approximately 49% of eligible participants reported being postmenopausal and 51% being premenopausal. A significant downward trend was observed in vigorous physical activity among EA women for incident and prevalent breast cancer (p= 0.002 and 0.04), whereas no clear trend was seen among AA women due to small sample size. Similar trends can be seen in vigorous physical activity postmenopausal EA women (p= 0.005 and 0.002). The beneficial association was not observed among AA women. On the other hand, overall physical activity appears to be positively associated with breast cancer among AA women (p for trend = 0.04). Conclusions: There appears to be a beneficial effect of vigorous physical activity and breast cancer among EA, regardless of pre- or postmenopausal status. However, the effect does not seem to apply to AA women, which could be the result of small number of breast cancer cases in African Americans. The current physical activity recommendations may not be applicable to all racial groups. We may be able to get a better race-specific recommendation regarding the level of leisure physical activity by pooling our data with other studies.

Socio-ecological correlates of physical activity in breast and colon cancer survivors 4 years after participation in a randomized controlled exercise trial (PACT study)

Having a physically active lifestyle after cancer diagnosis is beneficial for health, and this needs to be continued into survivorship to optimize long-term benefits. We found that patients, who participated in an 18-week exercise intervention, reported significant higher physical activity (PA) levels 4 years after participation in a randomized controlled trial of supervised exercise delivered during chemotherapy (PACT study). This study aimed to identify social-ecological correlates of PA levels in breast and colon cancer survivors 4 years after participation in the PACT study. Self-reported PA levels and potential correlates (e.g. physical fitness, fatigue, exercise history, and built environment) were assessed in 127 breast and colon cancer survivors shortly after diagnosis (baseline), post-intervention and 4 years later. Multivariable linear regression analyses were performed to identify social-ecological correlates of PA 4 years post-baseline. The final model revealed that lower baseline physical fatigue (β = -0.25, 95% CI -0.26; -0.24) and higher baseline total PA (0.06, 95% CI, 0.03; 0.10) were correlated with higher total PA levels 4 years post-baseline. Higher baseline leisure and sport PA (0.02, 95% CI 0.01; 0.03), more recreational facilities within a buffer of 1 km (4.05, 95% CI = 1.28; 6.83), lower physical fatigue at 4-year follow-up (-8.07, 95% CI -14.00; -2.13), and having a positive change in physical fatigue during the intervention period (0.04, 95% CI 0.001; 0.07) were correlates of sport and leisure PA levels 4 years post-baseline. This study suggests that baseline and 4-year post-baseline physical fatigue, and past exercise behaviour, were significant correlates of PA 4 years after participation in an exercise trial. Additionally, this study suggests that the built environment should be taken into account when promoting PA. Understanding of socio-ecological correlates of PA can provide insights into how future exercise interventions should be designed to promote long-term exercise behaviour.

Effects Of A Peer-led Aerobic Training Program On Physical Activity Behavior Of Urban College Students

PURPOSE: Peer-based education is commonly used on college campuses to provide health information. Using it to introduce physical activity to ethnically-diverse sedentary students attending an urban commuter college has not been explored. We examined the impact of a 10-week peer-based aerobic-exercise (AE) training program on urban college students’ leisure physical activity behavior. METHODS: Inactive students (N = 23, mean age: 21 ± 2.24 yrs) participated in a 10-week training program consisting of approximately 3 weekly AE sessions. Once-per-week sessions led by a peer-student trainer included a short lecture on exercise’s health benefits followed by 30 mins of AE (55%-65% HRR); participants were instructed to complete 2 other AE sessions independently per week and completed weekly online journals to assess adherence. Pre- and post-training evaluations of AE behavior patterns [International Physical Activity Questionnaire (IPAQ)] were conducted in the weeks prior to and following the exercise program and one month (30-IPAQ) and 90 days (90-IPAQ) after the conclusion of training. Descriptive statistics describing program participation and adherence are presented. Paired-samples t-tests were conducted comparing pre- and post-training cardiovascular fitness. RESULTS: Each week 19.1 ± 1.66 participants attended a peer-led session, training at THR of 142.61 ± 22.88. Participants completed a mean of 8.3 ± 1.26 sessions out of the expected 10. They completed a mean of 2.39 ± 1.95 d·wk-1; 34.85 ± 19.62 min·session-1 independently. Twenty (86.96%) participants completed the 90-IPAQ thus, students’ leisure physical activity analysis included only these 20 participants. Pre-IPAQ data demonstrated that 25% of participants engaged in leisure physical activity at a mean of 164 ± 120 MET-min·wk-1. One month following the training period 60% of participants exercised at a mean of 434.38 ±395.76 MET-min·wk-1; 90-IPAQ data demonstrated 55% of participants continued to engage in leisure physical activity at 488.73 ± 381.33 MET-min·wk-1 on average. There was no significant effect of aerobic training on participants’ cardiovascular fitness level. CONCLUSION: Participation in a peer-led aerobic training program may serve as a gateway to adopting a low level of leisure physical activity by urban college students.

Barreiras associadas à prática de atividade física no tempo livre de idosos com insuficiência cardíaca

&#x0D; &#x0D; &#x0D; &#x0D; O objetivo deste estudo foi analisar a associação entre as barreiras para a prática de atividade física com o nível de atividade física no tempo livre de idosos com insuficiência cardíaca.Trata-se de um estudo transversal, no qual foram analisados dados de 156 idosos (40,4% mulheres) de 60 a 92 anos de idade de um ambulatório acadêmico de insuficiência cardíaca. Foram analisados os dados referentes a informações sociodemográficas, comorbidades, comportamento de risco, barreiras para atividade física e prática de atividade física no tempo livre. Para verificar a associação entre as variáveis foi utilizado o teste Qui-quadrado para tendência. Dentre as barreiras relatadas pelos idosos, as principais foram associadas com a condição clínica, como: falta de ar (27,4%), fraqueza nas pernas (21,7%) e dor nas pernas (19,1%). O nível de atividade física no tempo livre dos idosos apresentou diferença significativa conforme o número de barreiras percebidas (p = 0,018), onde idosos que relataram mais barreiras eram mais inativos fisicamente. Considerando esses achados, estratégias devem ser desenvolvidas para que haja uma educação em saúde a fim de salientar os benefícios da atividade física a longo prazo no controle das principais barreiras, para que os idosos tenham maior chance de iniciar e manter uma prática regular de atividade física.&#x0D; &#x0D; &#x0D; &#x0D;

Long-term Physical Activity Levels and Physical Functioning Outcomes After Midurethral Sling.

The objective of this study was to describe changes in leisure physical activity (PA) levels and physical functioning (PF) in women 60 months or more after midurethral sling for stress urinary incontinence (SUI). This is a long-term follow-up study of a previously published prospective study of women undergoing outpatient midurethral sling for SUI from 2009 to 2011. Women completed questionnaires for incontinence, PA, and PF at baseline, 6, 12, and 60 months or more postoperatively. Women were categorized as having sedentary, insufficient, or sufficient leisure PA levels by metabolic equivalents (MET min/week on the International Physical Activity Questionnaire). Physical functioning was measured from the National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System. Physical activity and PF levels were compared preoperatively and at 60 months or more. Statistical tests were applied as appropriate with a P < 0.05 considered significant. Of the 85 women enrolled in the primary study, contact was made with 49, and 35 completed surveys. The follow-up range was 5.8 to 8 years (median, 6.8). Baseline mean age was 49.8 (SD, 8) years. Urinary Impact Questionnaire scores were lower at 60 months or more postprocedure (33.33 vs 0, P < 0.001), with no differences at 6, 12, and 60 months or more. At baseline, 31.3% of patients had sedentary, 12.5% had moderate, and 56.3% had sufficient leisure PA levels. On long-term follow-up, this improved to 21.9% sedentary, 12.5% moderate, and 65.6% sufficient leisure PA levels. Physical functioning also improved (mean, 44.95 vs 53.18 points; P < 0.001). Midurethral sling procedures are associated with modest improvements in leisure PA levels and significant improvements in PF 60 months or more after surgery.

Physical performance in relation to menopause status and physical activity.

The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n = 233), perimenopausal (n = 381), or postmenopausal (n = 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking speed, and 6-minute walking distance. PA level was assessed by self-report and categorized as low, moderate, or high. Multivariate linear regression modeling was used for data analysis. After including fat mass, height, PA, and education in the model, the postmenopausal women showed 12.0 N weaker (P < 0.001) handgrip force and 1.1 cm lower (P < 0.001) vertical jumping height than the premenopausal women. There was no significant interaction between menopausal stage and PA on physical performance. The peri- and postmenopausal women with a high PA, however, showed better performance in the maximal knee extension strength and 6-minute walking test, and showed greater lower body muscle power than those with a low PA. Menopause status is associated with muscle strength and power, whereas the association between menopause status and mobility/walking is clearly weaker. A high leisure PA level provides more capacity to counteract the potential negative influence of menopausal factors on muscle function.

Abstract C42: Correlates of health-related quality of life among African-American survivors of ovarian cancer: Results from the AACES Study

Abstract Background: The incidence of epithelial ovarian cancer (EOC) is lower among African-American (AA) women compared to European American (EA) women (9.8 vs. 13.0 cases/100,000), but AA women have markedly worse outcomes. The purpose of this study is to describe the health-related quality of life (HRQL) in AA women with EOC and its correlates using data from a multisite population-based case-control study of invasive EOC in AA women, the African American Cancer Epidemiology Study (AACES). Methods: 215 cases completed a first annual follow-up questionnaire, including the HRQL and psychosocial surveys &amp;lt;18 months post diagnosis. The primary HRQL outcome was assessed with SF-8 component scores for physical (PCS) and mental (MCS) health. Correlates examined were patient, disease and treatment characteristics, modified Charlson index, perceived social support, perceived discrimination, leisure-time physical activity, the Life Orientation Test (LOTR), and phobic anxiety (Crown-Crisp Inventory, CCI-PA). Ordinary least squares regression was used to estimate linear trend effects for all predictors adjusting for age at diagnosis, comorbidity, BMI, stage and income. Results: Higher household family income, lower phobic anxiety, higher social support, and higher leisure physical activity levels were associated with higher MCS and PCS (p &amp;lt; 0.01). Higher perceived discrimination was associated with both lower MCS and PCS, while higher optimism (LOTR) was associated with higher MCS. In multivariable analyses including all predictors, CCI-PA and LOTR remained significant predictors of MCS (p &amp;lt; 0.01), and BMI, phobic anxiety, and social support predicted PCS (p &amp;lt; 0.001). Conclusion: Prediagnosis characteristics and exposures of AA women with EOC are important predictors of HRQL after cancer diagnosis, and in AACES were more important than tumor characteristics. Cancer survivorship programs that enhance patients' social support and physical activity could have important benefits by reducing emotional distress and increasing perceived vitality.

Associação entre uso de internet e manter-se ativo no lazer, estudo longitudinal EpiFloripa Idoso

The aim of this study was to verify the association between internet use and physically active leisure time during four years in older adults included in the “EpiFloripa Idoso” study, a population and longitudinal study with older adults (60+) residents in Florianópolis, Brazil, interviewed in 2009-10 (baseline) and 2013-14 (follow-up). The outcome was self-reported level of leisure physical activity, measured by the long version of the International Physical Activity Questionnaire, classified as remaining inactive; becoming inactive; becoming active; remaining active. Covariates were: gender; age (in years); per capita income in Reais; schooling (years of study); internet use longitudinally measured (remaining not using, stopping using, starting using, remaining using); and cognitive decline at baseline assessed by the Mini Mental State Examination. Relative risk ratio (RRR) adjusted by independent variables were estimated. Participants were 1,705 older adults at baseline and 1,197 at follow-up. The prevalence of remaining physically active during leisure time was 15.8% (95% CI 12.6 to 19.0) and was associated with being male (RRR = 2.14, 95% CI 1.50 to 3.05), less schooling (RRR = 0.99, 95% CI 0.99 to 0.99), starting using (RRR = 4.1, 95% CI 2.06 to 8.55) and remaining using the internet (RRR = 5.52, 95% CI 3.25 to 9.36). This study can contribute to public policies for active and healthy aging through stimulation of internet use, since this technological behavior can help increasing the level of leisure physical activity in this population.

70: Long-term improvements in physical activity levels and physical functioning after midurethral sling for female stress urinary incontinence

To estimate the long-term effect of the midurethral sling on leisure physical activity (PA) levels and physical functioning (PF) in women 5 or more years after surgery for stress urinary incontinence (SUI). We conducted a long-term follow-up study of a previously published prospective, observational study of women undergoing outpatient midurethral sling for SUI from 2009 to 2011. For the primary study, and this follow-up study, women completed validated questionnaires for incontinence, leisure PA, and PF at baseline and postoperatively. The questionnaires included the UDI-6, International Physical Activity Questionnaire (IPAQ), Pelvic Floor Distress Inventory-20 (PFDI-20), Body Image Scale (BIS), and the NIH Patient-Reported Outcomes Measurement Information System measure for physical functioning (PROMIS-PF). Women were categorized as having sedentary, insufficient, or sufficient leisure PA levels by metabolic equivalents (MET-min/week on the IPAQ). They were also categorized as having low, moderate, or high overall PA levels using IPAQ scoring rules. For this follow-up study, all patients who consented to participating in future studies at the time of enrollment in the initial study were contacted via telephone to complete questionnaires through mail or e-mail. PA and PF levels were compared pre-operatively and at 5 or more years follow-up. Paired T-tests, signed-rank tests, and linear regression were used to estimate the effect of improvements in urinary symptoms on PA levels and PF scores at long-term follow-up. Of the 85 women enrolled in the primary study, 48 consented to being contacted for future studies. Of these, 28 completed surveys through mail or e-mail (58% response rate) and the long-term follow-up range was 5 to 7.5 years. The baseline mean age of the 28 participants was 51 years (SD 8), 64.3% had comorbidities, mean baseline UDI score was 50.3 points (SD 22.4). At baseline, no patients were categorized as having low overall PA, 26.9% were categorized as moderate, and 73.1% were categorized as high. 26.9% were categorized as having sedentary baseline leisure PA levels, 15.3% as insufficient, and 57.7% as sufficient. At long-term follow-up, 57.1% of women with low baseline leisure PA levels improved to moderate or high levels and 50.0% of women with moderate leisure PA improved to high leisure PA levels (P = 0.6). For overall PA levels, 7.7% improved their overall level of PA, while 53.8% maintained the same level of overall PA (P > 0.05). PROMIS-PF scores improved significantly between baseline and long-term follow up (mean 44.8 vs 52.9, P < 0.0001). When comparing 6 month post-operative results to long-term follow-up, BMI remained stable (29.78 vs 29.23), as did PFDI (11.98 vs 14.06), and BIS (4 vs 3) scores (all P > 0.05). On multiple linear regression, each 11- point improvement in UDI was associated with a mean improvement of 1.32 points in PF scores (P = 0.04), adjusting for age, comorbidity and baseline PA level at long-term follow up. Midurethral sling procedures for SUI are associated with long-term improvements in PA levels and PF.

Leisure-time physical activity and sciatica: A systematic review and meta-analysis.

The role of leisure-time physical activity in sciatica is uncertain. This study aimed to assess the association of leisure-time physical activity with lumbar radicular pain and sciatica. Literature searches were conducted in PubMed, Embase, Web of Science, Scopus, Google Scholar and ResearchGate databases from 1964 through August 2015. A random-effects meta-analysis was performed, and heterogeneity and small-study bias were assessed. Ten cohort (N=82,024 participants), four case-control (N=9350) and four cross-sectional (N=10,046) studies qualified for meta-analysis. In comparison with no regular physical activity, high level of physical activity (≥4 times/week) was inversely associated with new onset of lumbar radicular pain or sciatica in a meta-analysis of prospective cohort studies [risk ratio (RR)=0.88, 95% CI 0.78-0.99, I2 =0%, 7 studies, N=78,065]. The association for moderate level of physical activity (1-3 times/week) was weaker (RR=0.93, CI 0.82-1.05, I2 =0%, 6 studies, N=69,049), and there was no association with physical activity for at least once/week (RR=0.99, CI 0.86-1.13, 9 studies, N=73,008). In contrast, a meta-analysis of cross-sectional studies showed a higher prevalence of lumbar radicular pain or sciatica in participants who exercised at least once/week [prevalence ratio (PR)=1.29, CI 1.09-1.53, I2 =0%, 4 studies, N=10,046], or 1-3 times/week (PR=1.34, CI 1.02-1.77, I2 =0%, N=7631) than among inactive participants. There was no evidence of small-study bias. This meta-analysis suggests that moderate to high level of leisure physical activity may have a moderate protective effect against development of lumbar radicular pain. However, a large reduction in risk (>30%) seems unlikely. Leisure-time physical activity may reduce the risk of developing lumbar radicular pain.

Associação entre intenção para prática de atividade física, apoio social e atividade física

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n6p667 Intrapersonal and interpersonal aspects have been widely correlated to variations on the physical activity (PA) levels. The aim of this study was to examine the moderating effect of intention for PA practice on the association between social support and leisure PA levels in a sample of college students from Curitiba, Brazil. A questionnaire was administered in a sample of 349 college students from a Physical Education undergraduate program. The variables intention to PA practice, social support (family and friends) and leisure-time PA were obtained through interviews. Poisson regression was used to test the moderating effect of intention to PA practice on the association between social support and leisure-time PA levels. The intention for PA practice showed no moderating effects on leisure PA. Social support from friends was associated with achieving recommended PA levels (≥150min/week), regardless of intention for PA practice (PR: 1.45; 95% CI: 1.09-1.93). In this study, moderating effect of intention for PA practice on the association between social support and leisure-time PA has not been found.

The impact of lifestyle intervention on sedentary time in individuals at high risk of diabetes.

The Diabetes Prevention Program (DPP) lifestyle intervention successfully achieved its goal of increasing leisure physical activity levels. This current study examines whether the lifestyle intervention also changed time spent being sedentary and the impact of sedentary time on diabetes development in this cohort. 3,232 DPP participants provided baseline data. Sedentary behaviour was assessed via an interviewer-administered questionnaire and reported as time spent watching television specifically (or combined with sitting at work). Mean change in sedentary time was examined using repeated measures ANCOVA. The relationship between sedentary time and diabetes incidence was determined using Cox proportional hazards models. During the DPP follow-up (mean: 3.2years), sedentary time declined more in the lifestyle than the metformin or placebo participants (p < 0.05). For the lifestyle group, the decrease in reported mean television watching time (22 [95% CI 26, 17] min/day) was greater than in the metformin or placebo groups (p < 0.001). Combining all participants together, there was a significantly increased risk of developing diabetes with increased television watching (3.4% per hour spent watching television), after controlling for age, sex, treatment arm and leisure physical activity (p < 0.01), which was attenuated when time-dependent weight was added to the model. In the DPP, the lifestyle intervention was effective at reducing sedentary time, which was not a primary goal. In addition, in all treatment arms, individuals with lower levels of sedentary time had a lower risk of developing diabetes. Future lifestyle intervention programmes should emphasise reducing television watching and other sedentary behaviours in addition to increasing physical activity. ClinicalTrials.gov NCT00004992.

Improvements in Physical Activity and Functioning After Undergoing Midurethral Sling Procedure for Urinary Incontinence

The primary objective was to estimate the effect of the midurethral sling on improving leisure physical activity levels and physical functioning in women with stress urinary incontinence (SUI). Our secondary objective was to identify possible risk factors for postoperative insufficient physical activity. We conducted a prospective, observational study of women undergoing outpatient midurethral sling for SUI. Women completed validated questionnaires for incontinence, leisure physical activity, and physical functioning at baseline and 6 months postoperatively. The primary outcome was leisure physical activity level. We used multiple logistic and linear regression to estimate the effect of improvements in urinary symptoms and life effect on physical activity levels and physical functioning scores. Ninety women underwent surgery and 85 returned for follow-up. At baseline, 38% had sedentary, 18% had moderate, and 44% had sufficient leisure physical activity levels. Postoperatively, this modestly improved to 26% sedentary, 20% moderate, and 54% sufficient levels. The median leisure physical activity energy expenditure increased from 396 to 693 metabolic equivalent-minutes per week (P=.04). Physical functioning scores also significantly improved (mean score 44 compared with 55 points, P<.001). On multiple logistic regression, improvements in incontinence life effect were associated with increased odds of leisure physical activity improvement (adjusted odds ratio 1.66; 95% confidence interval 1.08-2.54). On multiple linear regression, improvements in both urinary incontinence severity and effect were associated with improvements in physical functioning scores (P<.01 for both). Factors associated with insufficient postoperative physical activity included low baseline physical activity levels and smaller improvements in urinary effect scores. Midurethral sling and subsequent improvements in urinary incontinence are associated with improved leisure physical activity levels and physical functioning.
