Abstract Background Leptin is an adipose tissue-derived cytokine that plays a role in energy regulation and immune functions. High leptin levels and obesity have been associated with decreased risk of developing active TB. We aimed to characterize the association between body mass index (BMI) and leptin levels in patients at different stages of tuberculosis (TB). Methods Data from a cross-sectional cardiovascular risk study of 40 to 70 years old individuals enrolled in Lima, Peru, and Cincinnati, US, were analyzed. Four categories based on TB and treatment status were defined: no TB infection (QuantiFERON-TB test negative; n= 31), latent TB infection (LTBI; QuantiFERON-TB test positive; n= 43), active TB on treatment (in the continuation TB treatment phase; n= 30), and post-TB (within one year of TB treatment completion; n=16). BMI and plasma leptin levels were compared among the four groups using the Kruskal-Wallis test, followed by Dunn’s multiple comparison test if differences were found in the Kruskal-Wallis test. Multivariate ordered logistic regression models were used to assess factors associated with leptin levels, adjusted for potential confounders. Results The median age was 53 years, and 51% were female. BMI was different between study groups (p< 0.01), with LTBI individuals having the highest BMI compared to other groups; see Figure 1A. Leptin levels were marginally low in the group with active TB on treatment, but no significant differences were found between groups (p=0.44; see Figure 1B). In multivariate analysis, leptin was associated with female sex (OR 23, 95%CI, 9-58), BMI (OR, 1.5, 95%CI, 1.2-1.7), and coronary plaque ≥25% stenosis (OR, 0.29, 95%CI, 0.08-0.99). Body mass index (BMI) and plasma leptin levels in participants with negative QuantiFERON-TB test (QFN-), latent tuberculosis infection (LTBI), active tuberculosis on treatment (ATBT), and post-TB treatment (TB-treated). Significance was determined using the Kruskal-Wallis test, followed by Dunn’s multiple comparison test if the Kruskal- Wallis test p-value was <0.05. Conclusion LTBI individuals had a higher BMI compared to persons with active TB on treatment and post-TB. Higher leptin levels were associated with higher BMI, but we found no association between leptin and TB status in our cohort. Disclosures All Authors: No reported disclosures

Background Remaining underweight during Tuberculosis (TB) treatment is associated with a higher risk of unsuccessful TB treatment outcomes and relapse. Previous studies conducted in Ethiopia found that bodyweight not adjusted for height at the start of treatment is associated with poor treatment outcomes. However, the association of body mass index (BMI) and weight change during treatment with treatment outcomes has not been studied. We aimed to investigate the association of BMI at the time of diagnosis and after two months of treatment and TB treatment outcomes. Methods Using an ambi-directional cohort study design (retrospective and prospective), a total of 456 participants were enrolled among 30 randomly selected public health centers residing within six sub-cities of Addis Ababa, Ethiopia. Data were collected using medical chart abstraction and face to face interviews. We compared TB treatment outcomes in persons with a body mass index (BMI) <18.5kg/m2 (underweight) versus persons with BMI ≥18.5kg/m2 (normal or overweight) at treatment initiation and after two months of treatment. Treatment was classified as successful in persons who were free of symptoms and had a negative sputum smear for acid-fast bacilli at the end of the 6-month treatment course. We analysed outcomes using univariable and multivariable logistic regression with 95% CI and p value< 0.05. Results Of enrolled study participants, 184 (40.4%) were underweight and 272 (59.6%) were normal or overweight. Body mass index (BMI ≥18.5kg/m2) at the start and second month of treatment were independent predictors for successful treatment outcome (AOR = 2.15; 95% CI: 1.05, 4.39) and (AOR = 3.55; 95% CI: 1.29, 9.73), respectively. The probability of treatment success among patients with BMI≥18.5kg/m2 at the start and second month of treatment was 92.9% and 97.1%, respectively versus 86.5% and 91.7% in patients with BMI<18.5kg/m2. Bodyweight not adjusted for height and change in the bodyweight after the second and sixth months of treatment were not significantly associated with treatment success. Conclusion In persons treated for TB disease, being underweight at baseline and after two months of treatment was a predictor for unsuccessful treatment outcomes. Nutritional assessment, counselling, and management are important components of TB treatment programs with the potential to improve treatment outcomes.

Objective The aim of this study was to investigate a possible relationship between obesity and decreased mobility of the talocrural joint and in turn chronic venous disease. Subjects and methods One hundred obese patients recruited at Hospital Santa Casa de Maringa, Parana were enrolled by order of arrival at the hospital in a randomized quantitative cross-sectional study. Inclusion criteria were patients with a body mass index above 30 kg/m2 and the exclusion criteria were infectious conditions that would interfere with the assessment. Patients were graded according to the clinical, etiological, anatomical and pathophysiological classification. Talocrural goniometry was performed to assess the degree of mobility of the legs. The Kolmogorov–Smirnov normality test, Kruskal–Wallis test, Dunn's Multiple comparison test and analysis of variance were used for statistical analysis tests with an alpha error of 5% being considered acceptable. Results The increase in body mass index is correlated to the reduction in joint mobility (Kruskal–Wallis test: p-value <0.0001) and increase in clinical, etiological, anatomical and pathophysiological classification is correlated to a decrease in joint mobility and the increase in age is associated with an increase in clinical, etiological, anatomical and pathophysiological classification (Kruskal–Wallis test: p-value <0.0001). Conclusion Obesity is associated with deterioration in joint mobility and worsening of chronic venous disease.

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.

Abstract Background A significant relationship has been documented in the literature between the autonomic nervous system imbalance and cardiovascular mortality. In patients with autonomic failure, water ingestion has been shown to increase blood pressure (BP), induce bradycardia, and cause low heart rate variability (HRV). A few studies showed the altered HRV as an acute effect of ice water intake in healthy subjects. None of the studies have shown light on the relationship of BP and HRV to ice water intake in obese and overweight subjects. The present study is aimed to correlate BP and HRV with body mass index (BMI) after ice water ingestion. Methods This cross-sectional study included a total of 60 subjects of both sexes aged between 18 and 24 years old. Subjects were assigned into three groups based on their BMI: normal, overweight, and obese. Before and after ice water ingestion, BP and HRV parameters were recorded and compared between the groups. Statistically data were analyzed by Student’s paired t-test and one-way analysis of variance. Results Basal HF was significant (p<0.05) in all three groups after ice water ingestion [F(2, 27), 44.1; p-value, 0.02]. After ice water ingestion, all HRV values were significant (p<0.001) in the three groups. The post-hoc Tukey HSD test demonstrated the less mean score for mean RR interval, standard deviation of all NN interval, standard deviation of differences between adjacent, HF and high for HR, LF, and LHR in overweight and obese subjects. Conclusions Because of the effective buffering system, healthy subjects showed increased HR and unchanged BP. Overweight and obese subjects showed decreased HR and increased BP.

Objective: Obesity is a medical problem that increases the risk of health problems like diabetes. Hormones secreting from fat tissue, Leptin, are correlated with body mass index. Leptin reduces the personchr('39')s appetite by acting on specific centers of their brain to reduce their urge to eat. And insulin, a hormone produced by the pancreas, is essential for regulating carbohydrates and the metabolism of fat. A positive relationship between leptin levels and insulin resistance in children showing in this study is to determine the effect of continues-endurance and interval-endurance on leptin serum levels and insulin resistance in over-weighted youths. Materials and Methods: This study is a semi-experimental design. Thirty boys were voluntarily selected as a matched two experimental groups and a control. Physical profiles included aged 16-19, BMI; 37.75 (±4.46) KG/M2, base functional capacity: 32.8 (±3.6) ml/kg/min which dividing by three equal groups: the submaximal training interval, a continuum and interval and control group performed the submaximal running program for six weeks on 3 D/W. The selected parameters were evaluated for an intervention pre and post-conditions. Results: weight and body mass index variables were decreased by about 2.5-3% after exercise intervention. Plasmatic leptin levels were reduced by about 45% in the continuum and interval control groups. HOMA-IR & QUICKI indexes altered in the EG (8.9 %, 7.8%) (P-value < 0.05). Conclusion: Presumably, 2 exercise program patterns lower than lactate threshold could change body composition profile, basal leptin level, and blood glucose /insulin concentrations, which probably induced changes in resistance to insulin.

Women in postmenopausal period of their life face various physical and physiological changes causing lack of estrogen and progesterone hormones, changes in the reproductive and genitals organs, vasomotor system in the body along with mood related symptoms such as anxiety, etc. Lifestyle, body fat distribution and anthropometric changes adds on to the bone strength in postmenopausal women. It may be a risk factor for osteoporotic fracture, cardiovascular, metabolic diseases, etc. Core strength and stability is greatly influenced by body composition and adiposity. The aim of the study was to correlate the core strength assessed with the Body Mass Index (BMI) among postmenopausal women. The objective of the study is to find the correlation between the core strength assessed with the Body Mass Index using 60° flexion test, Beiring Sorenson test and Unilateral Hip Bridge Endurance test among postmenopausal women with age ranging from 46-70 years. 96 healthy postmenopausal women in Karad city with a natural history of menopause were selected for the study. Based upon BMI values, the subjects were grouped as Underweight (<18.5 kg/m2), Normal weight (18.5-24.9 kg/m2), Overweight (25-29.9 kg/m2 and more). The outcome values for strength were correlated with the BMI of postmenopausal women. In the study, the Pearson correlation(r) was -0.361 and the P value was 0.0003 showing extremely significant correlation between the BMI and 60° Flexion test. For the Beiring Sorenson Test, the Pearson correlation value was -0.305 and the P value was 0.0025 showing very significant correlation between the BMI and Beiring Sorenson Test. Correlation of BMI and Unilateral Hip Bridge Endurance Test shows a Pearson Correlation value of -0.322 and the P value 0.0013 claiming very significant correlation between the BMI and Unilateral Hip Bridge Endurance Test. The study concludes that there is a significantly negative correlation between the core strength and stability with the Body Mass Index among postmenopausal women.

Playing online games is a favorite activity for adolescents to fill their free time. This habit affects the occurrence of addiction if done for a long time. In addition, the long duration of play leads to sedentary lifestyle behaviors, which contribute to overweight among adolescents. The purpose of this study was to identify the relationship between online gaming addiction and being overweight among adolescents in Jember district. The cross-sectional study design was conducted among 162 overweight students from 16 senior high schools in Jember with stratified random sampling. The development of the Indonesian online game addiction questionnaire is used to assess online game addiction, weight scales, and stature meters are used to measure body mass index (overweight). The Spearman Rank test was performed to answer the objective of this study. The results of this study indicate that body mass index in 162 adolescents is overweight (Median=1,44; Standard Deviation=0,26) which indicates obesity. Adolescents who were identified as having addiction in the study were (27,2%) and mild addictions were (72,8%). There was a significant relationship between online game addiction and overweight (r=0.212 ; p-value = 0.007). The sedentary lifestyle of online game addiction contributes to the occurrence of overweight among adolescents. Therefore, regular physical activity patterns need to be applied to reduce sedentary lifestyle and overweight problems among adolescents.ABSTRAKBermain game online menjadi kegiatan favorit bagi remaja untuk mengisi waktu luang. Kebiasaan ini berdampak pada terjadinya kecanduan jika dilakukan dalam waktu yang lama. Selain itu, durasi bermain yang cukup lama mengarah pada perilaku gaya hidup yang menetap, yang berkontribusi pada terjadinya kelebihan berat badan di kalangan remaja. Tujuan dari penelitian ini adalah untuk mengidentifikasi hubungan antara kecanduan game online dan kelebihan berat badan di kalangan remaja di Kabupaten Jember. Desain penelitian cross sectional dilakukan di antara 162 siswa yang kelebihan berat badan dari 16 SMA di Jember dengan stratified random sampling. Kuesioner The development of Indonesian online game addiction questionnaire digunakan untuk menilai kecanduan game online, timbangan berat badan dan stature meter digunakan untuk mengukur indeks massa tubuh (kegemukan). Analisis uji menggunakan uji spearman rank untuk menjawab tujuan penelitian ini. Hasil penelitian ini menunjukkan bahwa indeks massa tubuh pada 162 remaja adalah (M = 1,44; SD = 0,26) didapatkan median >1 untuk Z score antropometri yang mengindikasikan kegemukan. Remaja yang diidentifikasi mengalami kecanduan pada penelitian adalah (27,2%) dan kecanduan ringan adalah (72,8%). Terdapat hubungan yang signifikan antara kecanduan game online dan kegemukan (r = 0,212; p value = 0,007). Gaya hidup menetap dari kecanduan game online berkontribusi terhadap terjadinya kegemukan di kalangan remaja. Oleh karena itu, perlu diterapkan pola aktivitas fisik secara teratur untuk mengurangi gaya hidup yang menetap dan masalah kelebihan berat badan di kalangan remaja.

AbstractKnee range of motion (ROM) is an important postoperative measure of total knee arthroplasty (TKA). There is conflicting literature whether patients who are obese have worse absolute ROM outcomes than patients who are not obese. This study analyzed whether preoperative body mass index (BMI) influences knee ROM after patients' primary TKA. A retrospective investigation was performed on patients, who underwent primary TKA at an academic institution, by one of three fellowship-trained adult reconstruction surgeons. Patients were stratified according to their preoperative BMI into nonobese (BMI < 30.0 kg/m2) and obese (BMI ≥ 30.0 kg/m2) classifications. Passive ROM was assessed preoperatively as well as postoperatively at patients' most recent follow-up visit that was greater than 2 years. Mann–Whitney U tests were performed to determine statistical significance at p-value <0.05 for ROM outcomes. No statistically significant differences were observed when ROM in the nonobese group was compared with ROM in the obese group both preoperatively (105.73 ± 11.58 vs. 104.14 ± 13.58 degrees, p-value = 0.417) and postoperatively (105.83 ± 14.19 vs. 104.49 ± 13.52 degrees, p-value = 0.777). Mean follow-up time for all patients was 4.49 ± 1.92 years. In conclusion, long-term postoperative ROM outcomes were similar between patients who were nonobese and patients who were obese.
