The main purpose of this study was to determine the impact of somatotypic profile and body mass index on the physical conditions of 12-14 year-old students, based on the results of tests for assessment to motor skills included in assessment system at the Physical education and sports in schools. The 64 young men and 70 girls we will explore are from two different schools in Blagoevgrad, which subsequently were divided into four groups: two groups for the boys and two for the girls. The study groups have antropometrichal parameters: height - 161.5 ± 8.2 cm, weight - 55.25 ± 18.26, and BMI of 21.01 ± 5.82 (M ± SD) for the boys and height 159.7 ± 7.22 cm, weight 52.02 ± 10.66 and BMI (kg / m2) 20.36 ± 3.85 (M ± SD) for the girls. The participants of this study completed 4 tests to determine the level of physical fitness, which are included in the System for Control and Assessment of the Achievements of the Students in Physical Education and Sports, used in the second stage of the primary education in Bulgaria until 2019 year. The functional tests were: for boys they are: 50m (sec) sprint running; 600 m (sec) for endurance; throwing a medicine ball 3 kg (cm) and standing long jump with both feet. For the girls: 50m (sec) sprint; 300m (sec) for endurance; sit ups (pc) and standing long jump with both feet (cm). The Score are from 1 to 5, depending on the value of the result. The somatotype was measured using the Heath-Carter method. The results show mean values for endomorph of 4.44 ± 1.47, for mesomorph of 4.94 ± 2.4, and for ectomorph of 3.12 ± 1.57 for the girls (mesomorph-endomorph) and values (M ± SD) of 3, 50 ± 1.58 for endomorphism, 5.74 ± 3.04 for mesomorphy and 3.28 ± 1.77 ectomorphy for the boys (balanced-mesomorph). We used GraphPad Prism version 3.0, for statistical analysis. The correlations between somatotype index, body mass index, and results of functional tests were calculated by coefficient of Pearson (p<0,05). We checked all possible relationships between ectomorphic, mesomorphic, and ectomorphic index with condition test results. Only 6 of them having significant correlation: between mesomorph and result of 50 m at Male7 r = 0.331, p = 0.048; between the ectomorph and the result of 50 m at Female7 r = -0.346, p = 0.045; between endomorph and 50 m result at Female7 r = 0.459, p = 0.006; between the endomorph and the result of a jump from the site at F7 r = -0.414, p = 0.0015; between mesomorphs and the result of a standing long jump of Female7 r = -0.519, p = 0.0016; between ectomorphs and a score of 50 m at Female1 r = -0.3359, p = 0.043 (Pearson). The most significant correlation was found between the BMI index and the 50 m result at Male7 r = 0.832, p <0.0001 (Pearson). We identified 11 of a total of 64 possible combinations; five of which between functional capability, BMI and six with somatotype index; five were low correlations (0.3–0.5) in the range r = 0.300– 0.340; only three high positive correlations were found in the range r = 0.693 - 0.832, p <0.0001 (Pearson); seven correlation dependencies were established with the result of the test for 50 m (sec); three with a jump test (cm) and one with 600 m (sec). In conclusion we can say that our hypothesis is not confirmed, because despite the normal weight, BMI and good somatotypic profile of the subjects , they have no statistically significant effect on the functional capabilities of students.

The aim of this study is to contribute expansion of knowledge about the level of the performance and health oriented fitness at represented students of Physiotherapy on Faculty of Health Studies Jan Evangelista Purkyně University in Ústí nad Labem. We compare resulting values with the values that were obtained by general population and students of Physical education and sports. Students participated these tests: progressive run for 20 meters, 2 kg heavy ball throw with both hands, standing long jump with both legs together, flexed – arm hang forward grip for woman, sit-up test 1 minute, deep bend in sitting position, Iowa Brace and calculated Body mass index (BMI). We asked two questions for our study. First, what is the level of motor skills students of Physiotherapy so academic students, what is the difference of level of motor skills between students of Physiotherapy compared with general population and second, what is the difference of the level of motor skills between students of Physiotherapy and students of Physical education and sports. Results showed that students of Physiotherapy had the same level of motor skills such as general population. Students of Physiotherapy had the same level in only two tests – deep bend in sitting position – flexibility and flexed-arm hang forward grip for woman with students of Physical education and sports.

Abstract Background Total knee arthroplasty is known to successfully alleviate pain and improve function in endstage knee osteoarthritis. However, there is some controversy with regard to the influence of obesity on clinical benefits after TKA. The aim of this study was to investigate the impact of body mass index (BMI) on improvement in pain, function and general health status following total knee arthroplasty (TKA). Methods A single-centre retrospective analysis of primary TKAs performed between 2006 and 2016 was performed. Data were collected preoperatively and 12-month postoperatively using WOMAC score and EQ-5D. Longitudinal score change was compared across the BMI categories identified by the World Health Organization. Results Data from 1565 patients [mean age 69.1, 62.2% women] were accessed. Weight distribution was: 21.2% BMI < 25.0 kg/m2, 36.9% BMI 25.0–29.9 kg/m2, 27.0% BMI 30.0–34.9 kg/m2, 10.2% BMI 35.0–39.9 kg/m2, and 4.6% BMI ≥ 40.0 kg/m2. All outcome measures improved between preoperative and 12-month follow-up (p < 0.001). In pairwise comparisons against normal weight patients, patients with class I-II obesity showed larger improvement on the WOMAC function and total score. For WOMAC pain improvements were larger for all three obesity classes. Conclusions Post-operative improvement in joint-specific outcomes was larger in obese patients compared to normal weight patients. These findings suggest that obese patients may have the greatest benefits from TKA with regard to function and pain relief one year post-op. Well balanced treatment decisions should fully account for both: Higher benefits in terms of pain relief and function as well as increased potential risks and complications.

It has been acknowledged that excess body weight increases the risk of colorectal cancer (CRC); however, there is little evidence on the impact of body mass index (BMI) on CRC patients’ long-term oncologic results in Asian populations. We studied the influence of BMI on overall survival (OS), disease-free survival (DFS), and CRC-specific survival rates in CRC patients from the administrative claims datasets of Taiwan using the Kaplan–Meier survival curves and the log-rank test to estimate the statistical differences among BMI groups. Underweight patients (<18.50 kg/m2) presented higher mortality (56.40%) and recurrence (5.34%) rates. Besides this, they had worse OS (aHR:1.61; 95% CI: 1.53–1.70; p-value: < 0.0001) and CRC-specific survival (aHR:1.52; 95% CI: 1.43–1.62; p-value: < 0.0001) rates compared with those of normal weight patients (18.50–24.99 kg/m2). On the contrary, CRC patients belonging to the overweight (25.00–29.99 kg/m2), class I obesity (30.00–34.99 kg/m2), and class II obesity (≥35.00 kg/m2) categories had better OS, DFS, and CRC-specific survival rates in the analysis than the patients in the normal weight category. Overweight patients consistently had the lowest mortality rate after a CRC diagnosis. The associations with being underweight may reflect a reverse causation. CRC patients should maintain a long-term healthy body weight.

AbstractBackgroundReferences from the Global Lung Function Initiative (GLI) are widely used to interpret children’s spirometry results. We assessed fit for healthy schoolchildren.MethodsLuftiBus in the school (LUIS) is a population-based cross-sectional study done from 2013-2016 in the canton of Zurich, Switzerland. Parents and children aged 6-17 years answered questionnaires about respiratory symptoms and lifestyle. Children underwent spirometry in a mobile lung function lab. We calculated GLI-based z-scores for FEV1, FVC, FEV1/FVC, and FEF25-75 for healthy White participants. We defined appropriate fit to GLI references by mean values ±0.5 z-scores. We assessed if fit varied by age, body mass index, height, and sex using linear regression models.ResultsWe analysed data from 2036 children with valid FEV1 measurements of which 1762 also had valid FVC measurements. The median age was 12.2 years. Fit was appropriate for children aged 6-11 years for all indices. In adolescents aged 12-17 years, fit was appropriate for FEV1/FVC (mean: -0.09; SD: 1.02) z-scores, but not for FEV1 (mean: -0.62; SD: 0.98), FVC (mean: -0.60; SD: 0.98), and FEF25-75 (mean: -0.54; SD: 1.02). FEV1, FVC, and FEF25-75 z-scores fitted better in children considered overweight (means: -0.25, -0.13, -0.38) than normal weight (means: -0.55, -0.50, -0.55; p-trend: <0.001, 0.014, <0.001). FEV1, FVC, and FEF25-75 z-scores depended on both age and height (p interaction: 0.034, 0.019, <0.01).ConclusionGLI-based FEV1, FVC, and FEF25-75 z-scores do not fit White Swiss adolescents well. This should be considered when using reference equations for clinical decision making, research and international comparison.Take home messageOur study suggests GLI-based FEV1, FVC, and FEF25-75 z-scores over detect abnormal lung function in Swiss adolescents, and more so among slimmer adolescents, which has important implications for clinical care, research, and international comparisons.

Background: Obesity is an established risk factor for acute ischemic stroke (AIS), but its impact on clinical outcomes and mortality after AIS remains controversial. In this study, we evaluate the association of body mass index (BMI) on outcomes after mechanical thrombectomy (MT) for large vessel occlusion acute ischemic stroke (LVOS). Methods: We reviewed our prospective MT database for LVOS between 2015 and 2018. BMI was analyzed as a continuous and categorical variable with underweight BMI <18.5, normal BMI 18.5-24.9, overweight BMI 25-29.9, and obese BMI>30. Multivariate analysis was used to determine predictors of outcome. Results: 335 patients underwent MT with 7 (2.1%) patients classified as underweight, 107 (31.9%) normal, 141 (42.1%) overweight, and 80 (23.9%) obese. Compared to normal weight (reference), obese patients had higher rates of hypertension and hyperlipidemia, while underweight patients had higher rates of previous stroke and presentation NIHSS. The time from symptom onset to puncture, procedural techniques, and reperfusion success (>TICI 2b) was not significantly different between BMI categories. There was a significant inverse linear correlation between BMI and symptomatic hemorrhagic. In patients with successful reperfusion (>TICI 2b), there was also a significant bell-shaped relationship between BMI and functional independence (mRS < 3) with both low and high BMIs associated with worse outcomes. In patients without post-procedural symptomatic hemorrhage, there was a significant linear correlation between BMI and inpatient mortality. Conclusion: In LVOS patients treated with MT, BMI is inversely related with post-procedural symptomatic hemorrhage. Yet in those whom reperfusion is achieved, both lower and higher than normal BMI were associated with worse functional outcomes. Thus, the obesity paradox does not appear to pertain to mechanical thrombectomy, although larger prospective studies are necessary.

Objective: Data on the association between body mass index (BMI) and dental caries in children with orofacial clefts are sparse. Therefore, studies on the impact of BMI on caries frequency in children with cleft lip and/or palate (CL/P) are of importance. The aim of the current study was to investigate the association between BMI and frequency of dental caries in children with and without CL/P. Height, weight, and BMI in children with CL/P were also compared to controls. Design: This study used a cross-sectional case-control design. Participants: One hundred and thirty-nine 5- and 10-year-old children with CL/P and 299 age-matched controls. Main Outcome Measures: Caries was recorded according to the International Caries Detection and Assessment System. Height and weight were recorded, and BMI was calculated as weight/height2. Results: There was no correlation between BMI and caries frequency. Weight, height, and BMI were significantly lower in all children with CL/P compared to controls. After adjustment for international adoption, only BMI was significantly lower in CL/P children compared to controls. Non-adopted children with CL/P were significantly heavier and longer than adopted children with CL/P. Conclusions: Five- and 10-year-old children with corrected CL/P seemed to have a lower BMI than controls, but there was no association between BMI and caries frequency. Internationally adopted children with CL/P were lighter and shorter than non-adopted CL/P children and controls.

Study objectivesObesity is often associated with lower lung function; however, the interaction of lung function with central obesity and physical inactivity is less clear. As such, we investigated the effect on lung function of body size (body mass index (BMI)), central obesity (waist circumference (WC)) and self-reported physical activity.MethodsLung function, height, weight and WC were measured in 22 743 participants (12 791 women), aged 45–75 years, from the EpiHealth cohort study. Physical activity, gender and educational level were assessed using a questionnaire.ResultsObesity, central obesity and physical inactivity were all associated with lower forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC). However, in participants without central obesity there was an increase in both FEV1 and FVC by BMI (% predicted FVC increasing from median 98%, interquartile range (IQR) 89–110% in underweight participants (BMI <20) to 103%, IQR 94–113% in obese participants (BMI ≥30)). In contrast, there was a decrease in % predicted FVC in participants with central obesity (from 98%, IQR 89–109% in the normal weight group to 95%, IQR 85–105% in the obese weight group). We further found a negative association between physical activity and lung function among those with low and high levels of physical activity (% predicted FEV1 97%, IQR 86–107% versus 103%, IQR 94–113%, respectively and % predicted FVC 96%, IQR 85–106% versus 103%, IQR 94–113%, respectively). All results remained when calculated by z-scores.ConclusionsThe association between BMI and lung function is dependent on the presence of central obesity. Independent of obesity, there is an association between physical activity and lung function.

AbstractBackground:Obesity is a modifiable, independent risk factor for mortality and morbidity after cardiovascular surgery in adults. Our objective was to evaluate the impact of obesity on short-term outcomes in adolescents undergoing surgery for congenital heart disease (CHD).Methods:This retrospective chart review included patients 10–18 years of age who underwent CHD surgery. Our exclusion criteria were patients with a known genetic syndrome, heart transplantation, and patients with incomplete medical records. The clinical data collected included baseline demographics and multiple perioperative variables. Charting the body mass index in the Centers for Disease Control and Prevention growth curves, the entire cohort was divided into three categories: obese (>95th percentile), overweight (85th–95th percentile), and normal weight (<85th percentile). The composite outcome included survival, arrhythmias, surgical wound infection, acute neurologic injury, and acute kidney injury.Results:The study cohort (n = 149) had a mean standard deviation (SD), body mass index (BMI) of 22.6 ± 6.5 g/m2, and 65% were male. There were 27 obese (18.1%), 24 overweight (16.1%), and 98 normal weight (65.8%) patients. Twenty-seven (18%) patients had composite adverse outcomes. Overweight and obese patients had significantly higher adverse outcomes compared with normal weight patients (odds ratio (OR): 2.9; confidence interval (CI): 1–8.5, p = 0.04 and OR: 3; CI: 1–8.5, p = 0.03, respectively). In multivariate analysis, obesity was an independent predictor of adverse outcome in our cohort (p = 0.04).Conclusions:Obesity is associated with short-term adverse outcome and increased health resource utilisation in adolescents following surgery for CHD. Further studies should evaluate if intervention in the preoperative period can improve outcomes in this population.

Background. The main purpose of this study was to explore the body-mass index and waist circumference associated with physical fitness by gender. Methods. In this cross-sectional study, we included 1036 adolescents (55.4% girls) from eight randomly selected secondary schools within the city of Zagreb (Croatia). Body-mass index and waist circumference were objectively measured. Physical fitness included three tests: (1) 1 min sit-ups, (2) standing long jump and (3) a sit-and-reach test. Associations were calculated using linear regression models. Results. Boys had higher body-mass index and waist circumference values, compared to girls (p < 0.001). They also performed better in 1 min sit-ups and the standing long jump tests (p < 0.001), while girls obtained higher values in the sit-and-reach test (p < 0.001). In boys, body-mass index and waist circumference were associated with 1 min sit-ups and the standing long jump. In girls, waist circumference was also associated with 1 min sit-ups and the standing long jump, while body-mass index was only associated with this standing long jump. Conclusions. Our study shows that anthropometric indices have non-linear associations with physical fitness tests in a large sample of Croatian adolescents. Screening for thinness and obesity to predict the level of physical fitness should be of a great interest.

Abstract Abstract 2784 Obesity, measured as body mass index (BMI), has been identified as a possible risk factor for the onset of several solid tumors as well as for chronic myeloid leukemia (CML). To date, no correlations have been reported in this latter disease between BMI at baseline and response to targeted therapies. We refer here on the impact of BMI on clinical response in CML. Three hundred and thirty-nine chronic phase (CP) CML patients treated with imatinib entered the study: 142 patients first received interferon alpha outside clinical trials and were then switched to imatinib for failure. For this group of patients, BMI was collected at the time of start of imatinib. The remaining patients were consecutively treated with imatinib first-line from January 2000 onward. BMI was defined as the individual's body weight divided by the square of his of her height and patients were categorised according to WHO into four categories: underweight (BMI < 18.5), normal weight (BMI 18.5-< 25), overweight (BMI 25-<30) and obese (BMI ≥ 30). All patients were followed according to ELN guidelines. We also analysed 25 CP-CML patients treated frontline with nilotinib. One hundred and fifty-six patients (46%) were categorized as underweight/normalweight, while 183 patients (54%) were classified as overweight/obese. BMI increased with age, with a median age of 29 years in underweight category, 43.4 years in normal weight, 54.9 years in overweight and 62.4 years in obese patients (p=0.001). We did not reveal statistically significant association between BMI and prognostic risk stratification at baseline, even when we used new EUTOS score, or type of BCR/ABL transcript. No statistically significant difference was revealed in terms of overall CCyR rate which was 87% for underweight/normal weight categories compared to 84% for overweight/obese group (p=0.34). If compared to patients with low BMI (< 18.5–25), patients with increased BMI (> 25–40) at diagnosis who received imatinib, showed a significantly longer median time to reach CCyR (6.8 months vs 3.3 months, p=0.01), a reduced rate of MMR (77% vs 58%, p=0.01) which was also achieved in a longer median time (29 months compared to 14 months, p=0.03). At 18 months, molecular kinetics revealed that median BCR-ABL/ABL ratio was 0.6% IS (range 0.001%-2%) in underweight/normal weight group compared to 1.6% IS (range 0.01%-3%) in overweight/obese category (p=0.01). Conversely, no differences were revealed with respect to BMI in patients treated frontline with nilotinib and also patients with increased BMI obtained rapidly CCyR and MMR, with an incidence similar to that of underweight/normal weight patients. These results suggest that CML patients with increased weight at baseline should be followed and carefully monitored if treated with standard dose imatinib frontline for a possible early switch to a second generation TKI or, as an alternative, should preferably be candidate to receive these drugs as a first line therapy.
