The relationships between cardiorespiratory fitness, daily physical activity, and selected coronary artery disease (CAD) risk factors were evaluated in a sample of 91 preadolescent boys. Cardiorespiratory fitness was assessed (VO2max). Physical activity level was assessed using daytime heart rate telemetry. CAD risk factors included total cholesterol, fasting triglycerides, HDL-cholesterol, LDL-cholesterol, fasting blood glucose, systolic and diastolic blood pressures, and body fat content. The mean value of VO2max exhibited significant negative relationship with body fat percent (r = -0.55). Controlling the effects of age, body mass index and body fat percent resulted in a significant inverse relationship between physical activity and systolic (r = -0.29) and diastolic (r = -0.28) blood pressures. Analysis of data by quartiles revealed significant differences only in body fat percent across fitness categories, while no significant differences were detected in the other CAD risk factors. However, higher HDL-cholesterol and lower triglycerides levels were observed in those boys with higher levels of physical activity. It was concluded that except with body fatness, cardiorespiratory fitness is not strongly associated with lower CAD risk factors, while physical activity level was significantly associated with lower blood pressure level but not with the other CAD risk factors.
Objective: Young patients with intracerebral hemorrhage (ICH) make up a small but important subgroup of patients with ICH. This study investigated the clinical characteristics and outcomes of hypertensive ICH in very young (18-45 years) and young (46-55 years) patients. Methods: This was a retrospective study of patients aged 18-55 years with hypertensive ICH admitted to a hospital from April 2014 to April 2019. Clinical and radiologic features as well as long-term clinical outcomes were compared between 2 age groups: group 1 (18-45 years) and group 2 (46-55 years). Factors affecting the clinical outcome were investigated as well. Results: Of 63 patients with hypertensive ICH, 24 (38.1%) were in group 1 (mean ± SD age of 38 ± 4.6 years), and 39 (61.9%) were in group 2 (50 ± 2.5 years). The risk factor profile was similar except for diabetes, which was more prevalent in group 1 (odds ratio [OR] = 4.65; 95% CI, 1.4-15.2). Patients in group 1 had higher mean ± SD NIH Stroke Scale scores (15.7 ± 4.6, P = .044), had lower Glasgow Coma Scale (GCS) scores (OR = 3.33; 95% CI, 1.0-10.8), were at higher risk of intubation (OR = 2.79; 95% CI, 1.1-9.9), and had higher ICH volume (21 ± 18, P = .034). Worse clinical outcome was higher in group 1 (OR = 5.14; 95% CI, 1.0-26.1). Low GCS score, mean hematoma volume, and intraventricular extension were independently associated with worse outcome. Conclusions: Relatively young patients with hypertensive ICH have higher prevalence of diabetes and worse clinical outcome in comparison to older patients with hypertensive ICH. Such patients should be monitored and treated more aggressively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
