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

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. 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 AdjustedActivity Status (AAS). ANOVA was used to investigate the sarcopenia between groups and Pearson's coefficient to investigate the association among variables. Fifty-four individuals with a mean age of 56±17.4years 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). 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.

Walkability and socio-economic status in relation to walking, playing and sports practice in a representative Spanish sample of youth: The PASOS study.

Physical activity (PA) provides multiple health-related benefits in children and adolescents, however, at present, the majority of young people are insufficiently physically active. The aim of this study was to evaluate if neighborhood walkability and/or socio-economic status (SES) could affect the practice of walking, play outdoors and sports practice in a representative sample of Spanish children and adolescents. A sample of 4092 youth (aged 8-16 years old) from 245 primary and secondary schools in 121 localities from each of the 17 Spanish autonomous communities participated in the study. Walk Score was used to evaluate walkability of the neighborhood and household income was used as an indicator of SES. A 7-item self-reported validated questionnaire, was used to assess PA levels, and in a subsample of 10% of the participants, randomly selected from the entire sample, PA was objectively measured by accelerometers. Youth from more walkable areas reported more minutes walking per day compared with those from less walkable neighborhoods (51.4 vs 48.8 minutes, respectively). The lowest average minutes spent in playing outdoors was found among participants from low-SES and low-walkable neighborhoods. Neighborhood SES influenced on the participation in team sports during the weekend, being this participation higher in high SES neighborhoods. Providing high walkable environments seems a good strategy to promote PA regardless SES levels. It seems that improving the walkability is a key component to partially overcome the SES inequalities, especially in urban areas with low SES. High-SES environments can offer better sports facilities and more organized physical activities than low-SES ones.

Gender Disparities in Health Biomarkers, Lifestyle Patterns, and Nutritional Status among Bank Staff: A Cross-Sectional Study.

Background and Objectives: Despite the importance of nutritional status and a healthy lifestyle in shaping overall well-being, little is known about examining gender-specific differences and trends in health, lifestyle, and nutritional status. The present study aimed to evaluate blood levels of micronutrients, homocysteine, and CoQ10, as well as physical activity (PA) levels and sedentary behavior, among a cohort of Austrian bank staff, with a particular focus on identifying gender differences as well as gender-specific nutritional deficiencies compared to the reference ranges. Materials and Methods: Following a cross-sectional study design, 123 Austrian bank staff (mean age: 43 years; 51% females) participated in this study. Blood samples were collected to evaluate participants' micronutrient status and serum levels of homocysteine and CoQ10. Whole-blood values of macronutrients were compared to gender-specific reference ranges and categorized into three groups: below, within, or over the range. The WHO's Global Physical Activity Questionnaire was used to assess PA levels and sedentary behaviors. Results: No significant difference between males and females was found for diet types, PA levels, sedentary time, homocysteine levels, or CoQ10 values (p > 0.05). A high PA level was reported by 64% of males and 58% of females. 71% of females and 56% of males were found to have a vitamin D deficiency. 63-98% of females and 72-97% of males showed normal blood levels for the remaining micronutrients, including potassium, calcium, magnesium, copper, iron, zinc, selenium, manganese, molybdenum, B6, B9, and B12. Conclusions: The findings highlight the necessity of implementing tailored strategies to foster healthy lifestyle behaviors, thereby enhancing the overall state of health, particularly in the context of occupational health.

Assessment of physical activity levels and back pain among poles and Portuguese in the further year of the COVID-19 pandemic - a pilot study

BackgroundThe vast majority of people have experienced the problem of back pain at least once in their lives for a variety of reasons. It is well known that regular physical activity at a moderate level has a number of health benefits regardless of age or gender with positive effects on the musculoskeletal, cardiovascular, respiratory or nervous systems improving fitness levels. During the pandemic, Poland experienced one of the longest periods of school lockdown in Europe. In Portugal, this period was considerably shorter. The aim of this study was to determine the level of physical activity and back pain as well as relationship between physical activity and back pain in a group of Polish and Portuguese students in the following year the COVID-19 pandemic.MethodsThe study was conducted via the Internet among students from Poland and Portugal (398 respondents − 229 from Poland and 169 from Portugal) in October 2022. In the pilot study, the International Physical Activity Questionnaire and The Oswestry Disability Index and Neck Disability Index questionnaires were used to assess the level of back pain.ResultsThere are no statistically significant differences in the level of physical activity and pain complaints of respondents from the two countries. At least half of the students do not report any pain complaints (median in some groups being 0). In the Portuguese men, there is a correlation between the level of physical activity and the Neck Disability Index score (p = 0.0304).ConclusionsThe following year, after the pandemic COVID-19 was declared, the prevalence of back pain among students in Poland and Portugal is still significant.

P1101 Patient-reported physical activity of IBD patients is of concern when weighed with the international physical activity questionnaire regardless of disease activity and IBD phenotype: barriers and facilitators emerged from the extended "BE-FIT-IBD" cross-sectional study

Abstract Background As the World Health Organization recommends, regular physical activity (PA) determines quality of life. The qualitative/quantitative characteristics of ideal PA to be suggested for inflammatory bowel diseases (IBD) nor the relationship with disease activity are not yet well defined. This study aimed to weigh PA levels and barriers/facilitators to PA in a cross-sectional group of patients with IBD. Methods Consecutive Italian non-severe IBD patients (assessed with partial Mayo score for and Harvey-Bradshaw index) received an anonymous online questionnaire to assess PA levels using the International Physical Activity Questionnaire (IPAQ), disease activity as Patient-Reported Outcomes 2 (PRO-2), and finally habits, beliefs, and barriers in conducting regular PA. Clinical, anthropometric, and demographic data were also collected. PA was processed as continuous units of resting metabolic rate in minutes/week (Met min/wk). Three PA groups were identified: inactive (&amp;lt; 700 Met min/wk), sufficiently active (700-2500 Met min/wk) and Health Enhancing PA (i.e., HEPA active, &amp;gt; 2500 Met min/wk) patients. Results The 219 patients enrolled exhibited overall PA levels of 834.5 Met min/wk, with a large proportion (94, 42.9%) classified as inactive. Only a minority (9, 4.1%) resulted as health-enhancing PA. Patients with a non-dyslipidaemia metabolic profile (p &amp;lt; 0.0001) or on biologics therapy (p=0.022) showed better IPAQ scores in moderate activities. PRO-2 correlated negatively with IPAQ intense activities scores (τ= -0.156, p=0.038) in ulcerative colitis patients. PRO-2 did not show notable sensitivity/specificity in predicting IPAQ inactivity (AUC &amp;lt; 0.6). IPAQ showed no notable differences when related to disease activity categories according to PRO-2 (p &amp;gt; 0.05). Physically active patients were more willing to discuss their PA with their IBDologists. Several barriers (e.g., diagnosis of IBD and fear of flare-ups after PA) are firmly rooted in physically inactive patients. Evacuation urgency (rectal syndrome) is the IBD-related barrier most physically inactive patients reported. Some fears about PA were worse felt in the absence of a stable partner (i.e., fear of worsening or recurrence of IBD, p &amp;lt; 0.05). Conclusion Many Italian IBD patients show a worrying rate of physical inactivity, depriving themselves of the multidimensional benefits that regular PA can bring. There is a need for IBDologists to act by removing barriers to PA and engaging in a regular discussion on the importance of PA with IBD patients. IPAQ has shown good feasibility and patient acceptance in this setting.

Do participants in a physical activity program from a Care Sport Connector become healthier? An explorative study from the Netherlands

Introduction Care Sport Connectors (CSCs) have been appointed to create a connection between the primary care and physical activity (PA) sectors to stimulate residents who are inactive to become more physically active to gain health benefits. The objective of this explorative study was to find out whether CSCs achieve these goals by testing the hypothesis that more residents become physically active, and score higher for health-related fitness and health-related quality of life. Method We conducted a longitudinal study design whereby participants (n = 402) were measured at three time points: at the start of their PA program (T0); after 6 months (T1); and after 1 year (T2). Participants conducted a fitness test to measure their health-related physical fitness and filled in questionnaires to assess PA level (PA-, Fit-, Combi-, and sport norm), health-related quality of life, motivation for PA, and personal information. We used a multi-level analysis to test whether outcomes of participants differ over time. Participants who dropped out and maintainers were compared with a chi-square test and a one-way ANOVA. Results This study showed that one-third of the participants dropped out (n = 139). Participants who dropped out were, compared with maintainers, less physically active (P = 0.004) and were more often reached in bigger municipalities, by an integral approach. More participants meet the PA norm (P = 0.007) and sport norm (P&lt;0.001) at T2 then at T0. Scores in health-related physical fitness and quality of life were significant but not a meaningful gain in health-related fitness. Conclusion More residents become physically active and participate in sport because they took part in a PA programs or activity organized by a CSC. Lifestyle interventions should be offered with a higher frequency, intensity, and focus on behavior change. It is necessary to invest in combined lifestyle interventions offered by a collaboration of primary care, welfare, and PA professionals.

Continuous-time modeling of the multivariate relationships between physical activity levels and stationary time in preschool-aged children: an investigation of the ActivityStat hypothesis

BackgroundThe ActivityStat hypothesis proposes that an increase or decrease in physical activity (PA) greater than a certain set point activates behavioural and/or energy compensatory responses to maintain a stable level of total energy expenditure. Few studies have tested this hypothesis in children and even fewer have focused on young children. Therefore, the purpose of this study was to investigate the ActivityStat hypothesis by examining the presence and timeframe of the relationships among PA levels and stationary time (ST) in preschool-aged children.MethodsA secondary analysis was performed on repeated measurement data (i.e., day-to-day activity) involving 98 preschool-aged children (age: 4.5 ± 0.7 years) in Edmonton, Canada. Participants were asked to wear an ActiGraph wGT3X-BT on the waist for 7 consecutive days to assess PA levels (i.e., light PA [LPA], and moderate-to-vigorous PA[MVPA]) and ST. Bayesian continuous-time structural equation modeling (CT-SEM) was used to examine the relationship between behaviours over time and the timeframe during which these relationships occur.ResultsEach behaviour (i.e., LPA, MVPA, and ST) positively and meaningfully predicted itself at a later time. These relationships persisted up to 0.5 days later, at which point past behaviour no longer meaningfully predicted future behaviour. In contrast, no relationships were observed between the three behaviours.ConclusionsThis is the first study to investigate the ActivityStat hypothesis using Bayesian CT-SEM in preschool-aged children. When simultaneously taking into account all dynamic relationships suggested by the ActivityStat, the findings fail to support the hypothesis.

The Association of Physical Activity Level with Micronutrient and Health Status of Austrian Bank Employees

Background: Favorable health benefits of an active lifestyle have been clearly documented within the context of occupational health. However, a knowledge gap exists regarding the monitoring and comparison of micronutrient status across varying levels of physical activity (PA). This study aimed to investigate the association of PA level with micronutrient status and the associated health biomarkers among a cohort of Austrian bank employees. Methods: Using a cross-sectional design, this study involved the participation of bank employees (n = 123; average age: 43 years; 49% males) from the federal state of Tyrol, located in the western part of Austria. To assess PA levels and sedentary behavior, the Global Physical Activity Questionnaire (GPAQ; developed by the WHO) was administered. Accordingly, participants were categorized into three groups: low PA, moderate PA, and high PA. Participants’ blood samples were obtained to measure blood levels of micronutrients, homocysteine, and CoQ10. The values of vitamins and minerals in whole-blood were compared to sex-specific reference ranges and grouped into three categories: below, within, or exceeding the reference range. Results: The prevalence of a high PA level was 61%, while 18% of participants had a low PA level. Overweight/obesity was significantly less prevalent among participants with high PA levels (22%) compared to those with moderate (50%) and low (50%) PA levels (p = 0.045). No significant differences between PA levels were found for sex, age, diet type, homocysteine, or CoQ10 markers (p &gt; 0.05). There was no significant PA-based difference in blood concentrations of most vitamins and minerals (p &gt; 0.05), except for vitamin D (p = 0.001) among females, as well as selenium (p = 0.040) and vitamin B12 (p = 0.048) among males. Conclusion: The present findings offer initial insights into the link between PA behaviors, micronutrient status, and health, highlighting potential implications in occupational health and lifestyle, specifically in developing tailored approaches based on PA levels.

Association between physical activity and health literacy in patients with Parkinson’s disease: an online web survey

BackgroundFor patients with Parkinson's disease (PwPD), promotion of habitual physical activity (PA) assists in the prevention of disease progression. Patients' health literacy (HL) is integral for meeting PA standards and turning it into a habit. This study evaluated the association between PA level and each HL domain in PwPD.MethodsOnline web-based assessment instruments and self-administered questionnaires, including the PA Questionnaire (IPAQ) Short Form and the Functional, Communicative, and Critical Health Literacy (FCCHL) scale, were used to assess PA levels and health literacy domains of PwPD.ResultsThe mean age of PwPD (n = 114) was 65.9 (SD = 11.6) years; 59.6% female, and the mean duration of disease was 6.4 (SD = 5.1) years. Of participants, 47.4% met the recommended criteria for PA. When comparing each HL domain by PA level, participants with lower PA had significantly lower critical HL (p = 0.03). Logistic regression analysis revealed that PA level correlated with critical HL (OR = 2.46; 95% CI = 1.16–5.19; p = 0.02).ConclusionsAdherence to recommended PA standards was associated with critical HL, but not other HL domains. Proactive attitudes to critically evaluate and utilize as well as understand health information may positively influence the promotion of PA.

Physical activity and exercise during pregnancy in Turkey: A narrative review

It is known that physical activity (PA) in pregnancy is beneficial for both women and fetal health. For the optimal exercise prescription, healthcare professionals interested in obstetrics-gynecology should evaluate women carefully before making any exercise recommendations during pregnancy. If there aren’t any contraindications, pregnant women should be encouraged to engage in regular physical activity. This narrative review aimed to determine PA during pregnancy in Turkey. A literature search was performed in the databases. A total of 29 original articles on PA during pregnancy in Turkey were included in this present study. Eighteen studies were chosen from among these articles for analysis. Two studies assessed PA levels in pregnancy with objective/direct methods such as PA monitors and pedometers, and non-objective/indirect methods were used in all 18 studies. Regarding exercise types, the most preferred exercises during pregnancy were walking, breathing exercises, strengthening exercises, and stretching neck muscles. This narrative review revealed that the level of PA participation and the frequency of regular exercise during pregnancy in Turkey is inadequate. More studies are necessary to examine PA participation from various contexts during pregnancy in Turkey to guide interventions for improving maternal health.

Physical Activity among Colorectal Cancer Patients and Survivors in Egypt.

Understanding physical activity (PA) levels is important when developing tertiary cancer prevention interventions, especially in Egypt where colorectal cancer (CRC) is more often diagnosed at later stages and at a younger age of onset (≤40 years). We assessed PA levels among CRC patients and survivors in Alexandria, Egypt. All participants completed two self-reported PA assessments: Global Physical Activity Questionnaire (GPAQ) and Godin Leisure-Time Exercise Questionnaire (GLTEQ). Participants could opt to wear an accelerometer for seven days. Results were compared against WHO recommendations of ≥150 minutes or ≥600 metabolic equivalents of tasks (METs) of moderate-to-vigorous PA weekly. Of 86 participants enrolled, all completed the surveys and 29 agreed to accelerometer use. Prevalence of meeting PA recommendations was 62.8% based on the GPAQ, 14.0% based on GLTEQ, and 41% based on accelerometer. Based on the GPAQ, very few respondents reported vigorous occupational, vigorous recreational, or moderate recreational activity (median = 0 with interquartile range [IQR] of 0 - 0 weekly minutes for all three) while most activity resulted from moderate occupational and transportation (median [IQR] of 60 [0-840] and 60 [0-187.5] weekly minutes, respectively). Participants meeting PA recommendations were less likely to be married (p = 0.043) according to GPAQ and more likely to be female (p=0.047) and early cancer stage (p=0.007) by GLTEQ. Non-leisure free-living PA is a major contributor to meeting PA recommendations while leisure-time PA is a potential target for future interventions that increase PA in this population.

Assessment of Physical activity Level and Sedentary Behaviour Among Pune City Police Personnel Using Global Physical Activity Questionnaire: A Survey

Background: Policemen being an integral part of the law implementation system have long working hours with huge workloads. They may not be able to save time for regular exercise or eat timely healthy meals which may put them at high risk of developing non-communicable diseases like cardiovascular diseases, diabetes, or lifestyle disorders such as obesity. The purpose of this study was to assess their existing physical activity level and sedentary behaviour using Global Physical Activity Questionnaire version 2.0. Objective: To assess the level of physical activity in police officers during work, travel and leisure-time and also determine the sedentary behaviour in them. Method: A cross-sectional study was conducted on 270 policemen, 168 males and 102 females, from 16 different police station of the Pune city using Global Physical Activity Questionnaire. Along with the analysis of demographic factors, data was analysed to evaluate if the study participants met the criteria for physical activity recommended by WHO. Participants were then divided into different categories depending on their energy expenditure i.e., MET-mins/week. Their sedentary behavior was calculated in terms of hours spent in sitting position. Result: Out of the total study participants, 50.4% were physically active and 49.6% were physically inactive.3.7% study participants were involved in the moderate-intensity physical activity at the workplace; 32.2% study participants were active in travel domain and 54.8%in leisure-time domain.12.2% of study participants were involved in vigorous-intensity physical activity in leisure-time domain only. 134 participants were inactive, 132 were low-active, 4 were moderately-active with not a single participant in highly-active category. The average amount of time spent sitting in the male participants was 6.11 + 3.03 hours whereas in female participants it was 7.50 + 2.62 hours. Conclusion: Even though 50.4% policemen were physically active, most of them were “low- active” and very few were “moderately-active” whereas not a single study participant was found to be “highly-active”. Sedentary behaviour in terms of average amount of time spent sitting was found to be more in female than male participants. Also,51.11% percentage of the study participants belonged to the overweight and obese category. Thus, there is huge scope for improving the physical activity level as well reducing the sedentary behavior in these professionals. KEY WORDS: GPAQ, physical activity, sedentary behavior, police personnel, Pune city.

Gender as a determinant of physical activity levels and mental health of medical students from Poland and Belarus in the context of the COVID-19 pandemic.

COVID-19 pandemic has brought about unfavourable changes regarding both physical activity (PA) levels and patterns of behaviour associated with mental health. The study sought to assess PA levels and kinesiophobia in medical students from Poland and Belarus taking account of gender. A total of 779 students (405 students from University of Grodno (UG), Belarus, and 374 students from John Paul II University of Applied Sciences (ABNS) in Biala Podlaska, Poland) took part in the study. Women constituted 74.2% of the study population. A diagnostic survey as well as two research tools, i.e., the International Physical Activity Questionnaire (IPAQ)-short form, and the Tampa Scale for Kinesiophobia (TAMPA) were employed in the study. Students from ABNS manifested significantly higher levels of PA. Taking into account gender, male respondents displayed significantly higher levels of MET-min/week (MET-metabolic equivalent of task). As for kinesiophobia, significantly higher levels were demonstrated by students from UG. Its higher levels were also noted among women. The findings of the study did not reveal strong correlations between kinesiophobia and PA levels in students from Poland and Belarus in the context of different approaches to the pandemic that both countries adopted. Students from ABNS proved to be more physically active. In turn, participants from UG exhibited significantly higher levels of kinesiophobia. Gender was the factor that significantly differentiated levels of kinesiophobia, with women displaying its higher levels.

Cross-sectional survey assessment of physical activity level and frequency of performing pelvic floor muscle exercises

Pelvic floor muscle (PFM) exercises are a non-invasive and effective treatment option for female pelvic floor disorders, but patient adherence is often poor, and predictors of adherence are limited. Our objective was to evaluate the relationship between physical activity level in women and self-reported frequency of performing PFM exercises. Women who responded to a cross-sectional survey through Research Match, a national online volunteer registry, were stratified into low, moderate, and high activity categories based on the International Physical Activity Questionnaire (IPAQ) Short Form. The Pearson Chi-square test was used to evaluate the association between activity level and the self-reported frequency of performing Kegels or PFM exercises. Multivariable logistic regression was used to assess the impact of physical activity level, demographic characteristics (including age, race, ethnicity, insurance status), and urinary symptoms (assessed by the Lower Urinary Tract Research Network-Symptom Index, LURN-SI 29) on performing PFM exercises several times a month or more. A total of 1,720 women were classified as having low (47.4%), moderate (26.3%), and high (26.3%) activity. More women in the high IPAQ category reported performing PFM exercises several times a month or more (17.0%, vs. 10.7% for moderate activity and 12.0% for low activity; P < 0.01). Women most commonly reported doing PFM exercises to improve sex (25.9%), to prevent getting a problem (17.8%), and because they were instructed to start doing them after childbirth (18.0%). Of women who provided a reason for not doing PFM exercises, those in the low and moderate activity groups were more likely to cite laziness as a reason compared to women in the high activity group (47.6% and 51.2%, respectively, vs. 38.7%; P = 0.02). On multivariable logistic regression, physical activity level and lacking insurance coverage were significant predictors of performing PFM exercises several times a week or more. Interventions aimed at increasing PFM exercise participation may benefit from linking to motivation, self-efficacy, and physical activity. The relationship between insurance coverage and frequency of performing PFM exercises warrants further exploration.

Propensity score-matched comparison of physical activity and quality of life between revision total hip arthroplasty and primary total hip arthroplasty

PurposeStudies on physical activity (PA) after revision total hip arthroplasty (THA) are limited. It is important to assess PA levels as well as improvements in physical function and pain after revision THA. The purpose of the study was to compare accelerometer-measured PA and health-related quality of life (HR-QoL) in patients 1–3 years after revision or primary THA. We also clarified the relationship between measured PA and HR-QoL. MethodsThis cross-sectional study included 64 patients who underwent revision THA and 188 who underwent primary THA 1–3 years earlier. Outcome measures were accelerometer-measured light PA, moderate-to-vigorous intensity PA, number of steps, questionnaire-based Oxford hip score, SF-8 physical and mental component scores. We conducted propensity-score matching for age, sex, comorbidities, body mass index, and postoperative follow-up duration and compared PA levels and HR-QoL scores between patients after revision THA and primary THA of each 50 patients. ResultsBased on propensity scores in the revision THA (68.3 years) and primary THA (67.8 years) groups, light PA, number of steps, and HR-QoL scores 1–3 years after revision THA were significantly lower than those after primary THA (P < 0.05). Moderate-to-vigorous intensity PA did not different between groups (P = 0.204). Measured light PA, moderate-to-vigorous intensity PA, and number of steps after re-THA were moderately correlated with HR-QoL scores. ConclusionIncreasing the time and frequency spent on light PA to the levels after primary THA may lead to an increase in overall PA levels after revision THA. A detailed understanding of PA, including light PA, in daily life and an approach that promotes activity levels are necessary.

Long-term exposure to fine particulate matter modifies the association between physical activity and the risk of hypertension.

The trade-off between the potentially detrimental effects of fine particulate matter (PM2.5) and the benefits of physical activity (PA) is unclear. We aimed to explore the independent and interaction effects between long-term PM2.5 exposure and PA on blood pressure (BP) and hypertension. A total of 8704 adults (≥45 years) without hypertension at baseline in a nationwide cohort of the China Health and Retirement Longitudinal Study (CHARLS) were followed from 2011 to 2015. The participants were selected using a four-stage, stratified, and cluster sampling procedure. The annual PM2.5 concentrations at the residential address were estimated from a two-stage machine learning model with a 10 km × 10 km resolution. A standard questionnaire collected information on PA and potential confounders, and metabolic equivalents (MET·h/wk), which combined frequency, intensity, and duration information, were used to assess PA levels. We adopted mixed-effects regression models to explore the independent and interaction effects between long-term PM2.5 exposure and PA on BP and risk of hypertension. Systolic blood pressure (SBP) decreased by -0.84 mmHg (95% CI: -1.34, -0.34) per an IQR (interquartile range, 175.5 MET·h/wk) increase in PA, and diastolic blood pressure (DBP) decreased by -0.42 mmHg (95% CI: -0.76, -0.07). Each IQR (36.1 μg/m3) increment in PM2.5 was associated with 0.48 mmHg (95% CI: -0.24, 1.20) in SBP and -0.02 mmHg (95% CI: -0.44, 0.39) in DBP. PM2.5 showed an elevated effect with risks of hypertension (odds ratio, OR = 1.01; 95% CI: 1.00, 1.03), while PA showed the inverse result (OR = 0.98; 95% CI: 0.97, 0.99). Interaction analyses indicated PA maintained the beneficial effects on BP, but the negative association was attenuated, accompanied by the increase of PM2.5. PA decreased the BP and hypertension risks, while PM2.5 showed the opposite results. PM2.5 attenuated the beneficial effects of PA on BP and modified the association between PA and the risk of hypertension.

Assessment of physical activity level, self-efficacy and perceived barriers to physical activity among adult Saudi women

ObjectivesGenerally, physical activity (PA) is accepted to have a crucial role in sustaining and improving individuals’ health. Consequently, it is considered a viable solution to the public health challenge of chronic diseases, particularly as sedentary behaviour is becoming a considerable concern worldwide. Therefore, this study focused on PA levels among adult Saudi women, and assessed the effects of self-efficacy, socio-demographic characteristics and perceived barriers on PA level. MethodsThis study used a quantitative cross-sectional descriptive design involving a self-reported web-based survey. The sample included 509 Saudi women recruited through purposive sampling. Data were collected with validated pre-existing questionnaires. The information provided by participants included their PA levels, self-efficacy and perceived barriers to PA. ResultsThe survey's completion rate was 51%. Analysis of the study sample responses indicated that the participants' had high levels of PA: 54% participated in vigorous PA, whereas 30% had insufficient PA (less than 600 MET m/week). In the sample, self-efficacy was moderate, and simple regression indicated that self-efficacy significantly affected the levels of PA (p = 0.001). The leading barriers to PA were a lack of resources and willpower. However, multiple regression indicated that only lack of willpower (p = 0.004), fear of injury (p = 0.043) and environmental barriers (p = 0.021) significantly influenced PA levels. Moreover, demographic characteristics had no significant effects on PA levels. ConclusionA large proportion of the study sample demonstrated sufficient levels of PA. Psychological determinants, including self-efficacy and willpower, significantly correlated with performance. The physical environment was also found to be a highly influential factor. These findings have implications for future initiatives and health promotion strategies targeted at Saudi women. The knowledge gained may be used to design theory based interventions for improving self-efficacy and willpower, while considering strategies for overcoming barriers to PA.

The Influence of Pregestational Body Mass Index and Physical Activity Patterns on Maternal, Delivery, and Newborn Outcomes in a Sample of Portuguese Pregnant Women: A Retrospective Cohort Study

Introduction: There is a linear association between pregestational body mass index (BMI) and almost all adverse pregnancy outcomes. Pregnancy is “a window of opportunities” in terms of changing behavior and improving awareness of healthy living. The proper assessment of physical activity levels, during pregnancy, determines trends, health benefits, and their effects over time. This study aims to describe maternal physical activity levels, stratified by pregestational BMI, verify the accomplishment of physical activity recommendations in pregnant women, and correlate pregestational BMI and physical activity accomplishment with maternal, delivery, and neonatal parameters. Methods: A retrospective cohort study was carried out with 103 pregnant women. Physical activity levels were evaluated using a questionnaire and accelerometry. Pregestational BMI was obtained through the Quetelet formula and used the American College of Sports Medicine’s guidelines were used to determine physical activity accomplishment levels. Continuous data were presented as mean and standard deviation and categorical data as numbers and percentages. The F test was used to examine the differences between groups. Results: Pregnant women in the sample spent 42.9% of their time on household activities, and for pregnant women with obesity, 91.5% of the time was spent on sedentary activities. Women with normative BMI had higher levels of moderate-intensity activities. Only 15.8% of participants with obesity reached the international recommendations for physical activity practice and women who accomplished physical activity recommendations gained less weight during pregnancy. A high percentage of pre-obesity and obese pregnant women exceeded the recommendations for gestational weight gain and the gestational diabetes prevalence was higher in the obesity group (p = 0.03 between groups). Regarding delivery and neonatal parameters (Apgar score 1st, Apgar score 5th, birth weight, length and head circumference), no statistical differences were found when adjusted to a gestational week at birth, between BMI (p = 0.58; p = 0.18; p = 0.60; p = 0.34; p = 0.34, respectively) or physical activity (p = 0.12; p = 0.15; p = 0.83; p = 0.70; p = 0.70, respectively) groups. Conclusion: Pregnant women with obesity, exhibit high levels of sedentary behavior, a high prevalence of gestational diabetes, and exceed recommended gestational weight gain. Healthcare professionals have a crucial role in promoting regular physical activity and lifestyle changes before and during pregnancy.

Physical activity, mental health and quality of life of women who have experienced COVID-19

Physical activity occupies an important place in maintaining and improving the health and well-being of individuals and the population, which is why physical activity stands out as an important lifestyle. The restrictive measures introduced due to the coronavirus pandemic have led to a significant drop in the level of physical activity, as well as an increase in anxiety and depression. The aim of this research was to determine whether there is a connection between physical activity, mental health and quality of life of women who have experienced COVID-19. The sample of respondents consisted of women between the ages of 20 and 60 (n=193). The IPAQ questionnaire (longer version) was used to assess physical activity. Selfassessment of mental health was determined by the longer version of the DASS questionnaire. Quality of life was assessed by the World Health Organization-WHOQOL questionnaire. Descriptive statistics parameters were calculated, and canonical correlation analysis was used to examine the relationship between the level of physical activity, mental health and quality of life. Canonical correlation analysis partially confirmed that there is an association between the level of physical activity and mental health parameters. There is no correlation between the level of physical activity and quality of life. In general, it is necessary for future research to include tests and measuring instruments in order to better understand the real effects of physical activity on mental and physical health after COVID-19 infection. For example, the use of an accelerometer in research would be important for an objective assessment of physical activity levels. Also, other factors that can directly or indirectly affect people's quality of life should be taken into account. Longitudinal research is necessary to examine the impact of different levels, forms and intensities of physical activity on mental health and quality of life after COVID-19 infection.
