In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
question:
Context: During reactive hyperemia, the brachial artery in some individuals constricts prior to dilation. Our aim was to describe the frequency of high-flow-mediated constriction (H-FMC) in adults, and its relationship to body composition and biomarkers of cardiovascular and metabolic risk.', 'Two hundred forty-six adults (124 male, 122 female; 36\u2009±\u20097 years old) were assessed for H-FMC via sonographic imaging of the brachial artery. Blood pressure, glucose, insulin, lipids, and body composition assessed via dual energy X-ray absorptiometry were collected. H-FMC was characterized as a 10-second average of maximal postocclusion constriction. Independent t test was used to compare H-FMC versus non-H-FMC individuals.', 'H-FMC was observed in approximately 69% of adult participants (54 obese, 57 overweight, and 59 normal weight). Total body mass (82.3\u2009±\u200917.5 versus 76.3\u2009±\u200916.3 kg, p\u2009=\u20090.012), fat mass (27.7\u2009±\u200911.5 versus 23.8\u2009±\u200910.5 kg, p\u2009=\u20090.012), body mass index (27.7\u2009±\u20094.9 versus 26.1\u2009±\u20095.0 kg/m\Question: Is high-flow-mediated constriction in adults influenced by biomarkers of cardiovascular and metabolic risk?
answer:
Increased body mass, fat mass, and body mass index were associated with a greater H-FMC. When H-FMC was present, the FMD response to reactive hyperemia was significantly lower. Because H-FMC has been observed to negatively affect FMD response to reactive hyperemia, we suggest that H-FMC should be noted when analyzing and interpreting FMD data. H-FMC may be an ancillary measure of endothelial health. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound, 2016.


question:
Context: To determine whether fertilization rate serves as a biological assay, reflects oocyte quality, and may be used to help predict patient implantation rate.', 'Retrospective cohort study.', 'Academic center.', 'Couples undergoing 3603 in vitro fertilization (IVF) cycles from 2001 to 2007.', 'None.', 'We compared the implantation rate among cycles with high versus low fertilization rate. Univariate analyses were performed to determine the association of implantation rate with potential confounding variables: age, day-3 follicle-stimulating hormone level, day-3 estradiol level, antral follicle count, oocyte number, cycle attempts, embryo grading, and number of embryos transferred. Multivariate analysis was then performed to determine whether the fertilization rate remained an independent predictor.', 'Cutoffs for fertilization rate were 50% for intracytoplasmic sperm injection (ICSI) and 75% for conventional insemination. Higher ICSI fertilization was statistically significantly associated with the implantation rate (25.2% vs. 17.8 %). After adjusting for variables associated with implantation rate, fertilization rate for ICSI remained a strong independent predictor of implantation. Higher conventional insemination fertilization was statistically significantly associated with implantation (32.1% vs. 25.7%) and remained a statistically significant predictor after adjustment.\Question: Is fertilization rate an independent predictor of implantation rate?
answer:
Fertilization is a strong, independent predictor of implantation rate and may be useful in modeling to guide decision making for the number of embryos to transfer.


question:
Context: Obesity is a cause of preventable morbidity and mortality with an increasing prevalence. Health promoting lifestyle activities maintain or improve an individual's health and in adolescence many habits are configured. The aim of this study was to determine the prevalence of overweight and obesity among adolescents and the relation between obesity and health promoting behaviors.", "This is a cross-sectional study including 848 high school students aged 15-17. All students were administered a questionnaire including the Health Promotion Life-Style Profile Scale. Weight and height were measured and body mass index was calculated. Descriptive analysis, Pearson's chi-square test, Kruskal-Wallis and Mann-Whitney U tests, and multivariate logistic regression analysis were used. P < 0.05 was considered statistically significant.", 'Of the included students, 80.8% (n = 685) had normal ranges of body mass index, 10.1% (n = 86) were overweight, and 9.1% (n = 77) were obese. The Health Promotion Life-Style Profile Scale average score was found to be 126.7 ± 20.4. There was no significant difference between Health Promotion Life-Style Profile Scale and obesity (P = 0.921).\Question: Are health promotion lifestyle profile scores associatedwith obesity in high school students?
answer:

Adolescence is an era of development when individuals start to implement their own features to life. According to this study adolescents do not perform health promoting lifestyles whether they are obese or not.
