Abstract Backgrounds: Cardiovascular Diseases (CVDs) are the first leading cause of death worldwide. The present study aimed to investigate the relationship between demographics, anthropometrics, sleep time, and physical activity and ECG parameters in Fasa Persian cohort study. Methods: In this cross-sectional study, the basic information of 10,000 participants aged 35-70 years in Fasa cohort study was used. The information used in this study included demographic data, main Electrocardiogram (ECG) parameters, anthropometric data, sleep time, and physical activity. Data analysis was performed using t-test, chi-square, and linear regression model. Results: The findings of this study suggested that increased age was significantly associated with all study parameters. Nevertheless, gender and body mass index showed no significant relationship with SV3 and PR. Wrist circumference، hip circumference, and waist circumference significantly increased the mean values of the ECG parameters. However, sleep time was not significantly associated with the ECG parameters. In addition, hypertension was a major comorbidity, which was shown to increase the mean values of the ECG parameters. Conclusion: A number of factors affected the ECG parameters. Thus, in order to interpret ECGs, in addition to age and gender, anthropometric indices, physical activity, and previous history of comorbidities, such as hypertension and ischemic heart disease, should be taken into consideration.

Background:Boolean remission criteria is one most popular and stringent criteria in treating patient with rheumatoid arthritis (RA), because it may guarantees a stable clinical course after attaining remission.Objectives:Impact of time span from initiation to achieving Boolean remission on maintaining disease activity, daily activities, and quality of life after attaining Boolean remission was investigated from daily clinical practice data.Methods:685 patients with RA since August 2010 under the T2T strategy were treated. They were monitored for their TJC, SJC, PGA, EGA, CRP, and disease activity indices such as CDAI, SDAI, DAS28, and Boolean criteria at every visit. HAQ-DI score, pain score using visual analog scale (PS-VAS), and EQ-5D were also monitored, and the quality of life score (QOLS) calculated from EQ-5D was determined at every visit from the time of diagnosis (baseline).Of 685 patients, 465 patients had achieved Boolean remission >1 times, and were consecutively followed up for >3 years. These patients were enrolled in the study. Time span from the first visit to first Boolean remission was calculated. The relationship between the time span and each of background parameters, and the relationship between the time span and each of the mean values of the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at the first Boolean remission and thereafter was evaluated statistically.Patients were subsequently divided into the G ≤ 6 and G > 6 groups based on the achievement of first Boolean remission within two groups: time span G ≤ 6 months and G > 6 months. The two groups were compared with regard to the SDAI score, HAQ score, PS-VAS, SHS, and QOLS at first visit and at the time of first Boolean remission, and the mean values of these parameters after remission were evaluated statistically. Moreover, changes of these parameters and the mean Boolean remission rate after the first remission, and SDAI remission rate at the first Boolean remission to thereafter were compared between the two groups statistically.Results:Out of 465 patients, females comprised 343 (73.7%), and the mean age was 67.8 years (range, from 21–95 years). The mean disease duration at first visit was 6.1 years (range, from 1 months–45 years). The mean follow up length was 88.1 months (range: 36–122 months; median: 85 months) and mean time span from the first visit to the first Boolean remission was 8.1 months. The mean SDAI score, HAQ score, PS-VAS, and the QOLS at first visit were 13.3, 0.467, 33.2, and 0.834, respectively. Among the study parameters, PS-VAS and QOLS were significantly correlated with the time span. For parameters at the first Boolean remission, HAQ-DI score, PS-VAS, and QOLS demonstrated significant correlation with the time span, whereas SDAI, HAQ-DI score, PS-VAS, SHS, and QOLS after the Boolean remission demonstrated significant correlation with the time span.The comparison between the G ≤ 6 and the G > 6 groups revealed that the disease duration, HAQ score, and PS-VAS at baseline in the G > 6 were significantly higher than that in the G ≤ 6 group, and QOLS in the G ≤ 6 group was significantly higher than that in the G > 6 group at baseline. Similarly, the HAQ score and PS-VAS at the first Boolean remission in the G > 6 group were significantly higher than that in the G ≤ 6 group, whereas QOLS in the G ≤ 6 group demonstrated no significant difference compared with that in the G > 6 group.The mean value of the SDAI score after the first Boolean remission in the G > 6 group was significantly higher than that in the G ≤ 6 group. Similarly, the SDAI score, HAQ score, and PS-VAS after the first Boolean remission in the G > 6 group were also significantly higher than those in the G ≤ 6 group, and the mean value of the QOLS in the G ≤ 6 group were significantly higher than that in the G > 6 group. The Boolean remission rate and SDAI remission rate after the first Boolean remission were significantly higher in the G ≤ 6 group than those in the G > 6 group.Conclusion:Attaining Boolean remission ≤ 6 months for RA has significant benefit for more stable disease control, that leads good maintenance of ADL.Disclosure of Interests:None declared

<p>The intensity and the spatial distribution of precipitation depths are known to be highly dependent on relief and geomorphological parameters. Complex environments like mountainous regions are prone to intense and frequent precipitation events, especially if located near the coastline. Although the link between the mean annual rainfall and geomorphological parameters has received substantial attention, few literature studies investigate the relationship between the sub-daily maximum annual rainfall depth and geographical or morphological landscape features.<br>In this study, the mean of the rainfall extremes in Italy, recently revised in the so-called I<sup>2</sup>-RED dataset, are investigated in their spatial variability in comparison with some landscape and also some broad climatic characteristics. The database includes all sub-daily rainfall extremes recorded in Italy from 1916 until 2019 and this analysis considers their mean values (from 1 to 24 hours) in stations with at least 10 years of records, involving more than 3700 stations.<br>The geo-morpho-climatic factors considered range from latitude, longitude and minimum distance from the coastline on the geographic side, to elevation, slope, openness and obstruction morphological indices, and also include an often-neglected robust climatological information, as the local mean annual rainfall.<br>Obtained results highlight that the relationship between the annual maximum rainfall depths and the hydro-geomorphological parameters is not univocal over the entire Italian territory and over different time intervals. Considering the whole of Italy, the highest correlation is reached between the mean values of the 24-hours records and the mean annual precipitation (correlation coefficient greater than 0.75). This predominance remains also in sub-areas of the Italian territory (i.e., the Alpine region, the Apennines or the coastal areas) but correlation decreases as the time interval decreases, except for the Alpine region (0.73 for the 1-hour maximum). The other geomorphological parameters seem to act in conjunction, making it difficult to evaluate, with a simple linear regression analysis, their impact. As an example, the absolute value of the correlation coefficient between the elevation and the 1-hour extremes is greater than 0.35 for the Italian and the Alpine regions, while for the 24-hours interval it is greater than 0.35 over the coastal areas.<br>To further investigate the spatial variability of the relationship between rainfall and elevation, a spatial linear regression analysis has been undertaken. Local linear relationships have been fitted in circles centered on any of the 0.5-km size pixels in Italy, with 1 to 30 km radius and at least 5 stations included. Results indicate the need of more comprehensive terrain analysis to better understand the causes of local increasing or decreasing relations, poorly described in the available literature.</p>

The mean and standard deviation over 24 h for 3 groups of animals - active, intermediate and inactive - in physical activity units were 10948 ± 3360, 2611 ± 1973 and 484 ± 316 respectively. The differences were significant ( P = 0·004), demonstrating the ability of the method to distinguish between groups that can be visibly differentiated. The small within-animal physical activity standard deviation (18·85 PAU) obtained in another group, suggests that it also yields reliable physical activity measurements for non-human primates. The monitoring device used can discriminate between individual nonhuman primate physical activity levels in a free-living environment and does not alter daily behaviour. This makes possible the study of the relationship between physical activity and atherosclerosis in nonhuman primates.

<p>Osteoporosis is a major public health priority in Iran and throughout the world. The prevention of osteoporosis has recently become the ultimate goal of many health professionals. Behavior change is one of the most powerful strategies to prevent osteoporosis. This study aimed to determine the predictive construct of physical preventive behavior of osteoporosis in women aged 30-50 in Khorramabad, west of Iran. This study included 269 women selected from all the health centers of Khorramabad city according to the inclusion criteria of the study and through random cluster and systematic sampling. The data gathering tools were valid and reliable questionnaires of demographic information, stages of change, decisional balance, self-efficacy, and physical activity. Data were analyzed using descriptive and inferential statistics. The mean of the subjects’ age was 38.72±7.003, and the mean of light weekly physical activity was 38.83±56.400. The results showed that the construct of self-efficacy had the highest predictive power of the preventive behavior. The results also showed that self-efficacy among the constructs of the Trans-theoretical Model was the only predictive construct for osteoporosis prevention behavior. Therefore, the findings of this study can serve as a base for educational interventions in behavioral changes to prevent of osteoporosis by health authorities.</p>

The aim: Assessment of physical activity of members of the Helicopter Emergency Medical Service. Material and methods: The study was conducted in a group of 131 people (65 paramedics, 66 pilots), members of HEMS teams from all bases in Poland, aged 27-59. The characteristics of physical activity was obtained using the author’s questionnaire. Results: The mean age of the study population was 42.73 ± 9.58 years. Pilots were significantly older than paramedics and had significantly higher BMI values (p < 0.05). No significant relationship between the age and BMI in the analyzed groups was found (p > 0.05), while the relationship between the frequency of physical activity and BMI was demonstrated. 70% of subjects undertook physical activity less than three times a week. The most frequently chosen forms were cycling, walking and swimming. Paramedics statistically significant more often than pilots chose wall climbing (p = 0.001). Downhill skiing (61%) was the most common declared winter sport played by pilots, while hiking in the mountains – by paramedics (49%). The most important reason for pilots to take up physical activity was concern for their health (47%), while for paramedics – the pleasure (63%). Paramedics statistically significant more often than pilots indicated a large number of other activities (90.6 vs. 74.2%) and financial issues (18.8 vs. 6.1%) as barriers that prevented more involvement in physical activities. Conclusions: The frequency of physical activity undertaken by HEMS members is insufficient. Low physical activity of HEMS team members has an adverse effect on their nutritional status. It is necessary to take initiatives to promote physical activity in this professional group.

In recent years, the concept of "metabolic syndrome" has become more spreading, and in parallel with disorders of carbohydrate and lipid metabolism, endothelial dysfunction is no less significant. The aim of our work was to analyze changes in homocysteine (HC) as a marker of metabolic syndrome in patients with an increased body mass index (IBMI) in polytrauma. The study involved 224 patients with polytrauma, who had different initial values of body mass index (BMI) and were treated at the polytrauma department and the intensive care unit for patients with combined injuries for a period from 1 day to 1 year since the moment of injury. All the patients were subjected to identifying the level of serum HC. The patients had the same severity according to the APACHE II scale, 14 ± 5.8, at the admission to the hospital, and were divided into 3 stratified clinical groups depending on the initial values of anthropometric parameters and BMI. The study was conducted on the 1, 3, 7, 14, 30 and 360 days from the date of polytrauma. Assessment of blood serum HC was performed by ELISA. It was found that the overweight patients with BMI ≤ 29.9 demonstrated an increase in the mean values of blood HC on the 7th and 14th days of the treatment, with a further decrease on the 15th day since the date of injury. For the patients with BMI within the range of 30.0 - 39.9, the persistence of the HC index during the first month of the treatment at baseline with an increase on the 360th day was found out. The patients with BMI ˃ 40.0 showed an increase in the level of blood HC through the year since the date of polytrauma. It was revealed that the level of HС directly affects the course of traumatic disease in patients with increased BMI, its severity in terms of uniformity of injuries received and the same range of severity according to the APACHE II scale depends on BMI at the admission to the hospital.

Abstract BACKGROUND Measuring physical activity and sedentary behavior accurately remains a challenge. When describing the uncertainty of mean values or when making group comparisons, minimising Standard Error of the Mean (SEM) is important. The sample size and the number of repeated observations within each subject influence the size of the SEM. In this study we have investigated how different combinations of sample sizes and repeated observations influence the magnitude of the SEM. METHODS A convenience sample were asked to wear an accelerometer for 28 consecutive days. Based on the within and between subject variances the SEM for the different combinations of sample sizes and number of monitored days was calculated. RESULTS Fifty subjects (67% women, mean±SD age 41±19 years) were included. The analyses showed, independent of which intensity level of physical activity or how measurement protocol was designed, that the largest reductions in SEM was seen as the sample size were increased. The same magnitude in reductions to SEM was not seen for increasing the number of repeated measurement days within each subject. CONCLUSION The most effective way of reducing the SEM is to have a large sample size rather than a long observation period within each individual. Even though the importance of reducing the SEM to increase the power of detecting differences between groups is well-known it is seldom considered when developing appropriate protocols for accelerometer based research. Therefore the results presented herein serves to highlight this fact and have the potential to stimulate debate and challenge current best practice recommendations of accelerometer based physical activity research.

The natural ecosystems are increasingly being replaced by urban built-up area due to fast urbanisation. The urban development pressure brought urban areas to the uncontrolled built environment which, in turn, significantly compromises the quality of public spaces and facilities. Furthermore, the urban environment discourages active living. Thus, research on the relationship between urbanisation and physical health is rapidly coming to the force. Urbanisation can have detrimental effects, particularly on physical health, which further attributed to unsustainable urban development. A study was carried out at Sri Pahang Public Housing (Flat), Kuala Lumpur with the aim to investigate the healthy lifestyle among residents and the relationship with the public facilities available at study area for the physical activity. Data was obtained through questionnaire survey. The relationship between healthy lifestyle particularly the level of physical activity and the facilities in the study area was analysed using correlation test. It was found that most of the respondents were physically inactive and their healthy lifestyle can be related to the planning aspects of facilities in the study area.

Background: The relationship between moderate to vigorous physical activity (MVPA) and fundamental motor skill (FMS) is inconsistent in early childhood, due to its complex and nonlinear characteristics. This study aimed to analyze the nonlinear relationships between MVPA, FMS, body mass index (BMI), sex, and age in preschoolers. Methods: This cross-sectional study with preschoolers (n = 204; 4.0 [0.8] y old; 99 boys), provided objective physical activity data, FMS assessments, and BMI. The associations between MVPA, FMS, BMI, sex, and age were explored using the network analysis (RStudio and qgraph). Results: Boys were more motor competent than girls in all FMS skills, while girls were more active than boys during the weekend. Older children were less active than their younger peers during these days. MVPA is weak and differently related to each FMS, and the leap skill emerged with the highest betweenness and strength values in the network. Conclusions: For the assessed preschoolers, when considering BMI, age, and sex, the relationships between MVPA and FMS are inconsistent, and leap emerged as the main variable. During early childhood, these variables are connected as part of a complex system in which each skill has a dynamic role within the emerging pattern.
