BACKGROUND Many youths and adults maintain a sedentary life style and a better understanding of the factors which influence physical activity is needed. This study analyses the association between social factors and low leisure-time physical activity in young adults. METHODS Three hundred and seventeen children aged 6-18 years participated in a health survey in 1979 and again 13 years later. ...

we have studied the patients who had a neck mass on presentation in five medical centers of tehran univ. of medical sciences (infectious disease department, ent department, dentistry faculty, cancer institute) during a period of 14 months. sixty patients, 20 women and 40 men, were eligible for our study. all patients underwent clinical and paraclinical work up and finally had histologic diagnos...

Although aging has been associated to slower V̇O2 kinetics, some evidence indicates that fitness status and not aging per se might modulate this response. The main goal of this study was to examine the V̇O2, deoxygenated hemoglobin+myoglobin (deoxy-[Hb+Mb]) kinetics, and the NIRS-derived vascular reperfusion responses in older compared to young men of different training levels (i.e., inactive, re...

Approximately 80% of new HIV infections in the United States occur in men. Four out of five men diagnosed with HIV infection are men who have sex with men (MSM), with an increasing proportion of young MSM (i.e. ≤24 years of age). We performed a retrospective analysis 11,873 cisgender men participating in a community based HIV screening program in San Diego between 2008 and 2014 to characterize ...

OBJECTIVES This study examines the effects of sleep restricted to four hours for three consecutive nights on blood parameters, known to be associated with cardiovascular risk, in young healthy men. MATERIAL AND METHODS Eight young healthy men (age 24.5 +/- 3.3 years) were studied in the sleep restricted group. Nine young healthy men (age 24 +/- 2 years) were included in the control group and ...

Background- Cardiovagal baroreflex sensitivity (BRS) declines with age but is favorably modulated by habitual aerobic exercise. We tested the hypothesis that compliance (transducing capacity) of an elastic artery in which baroreceptors are located is associated with these age-exercise interactions. Methods and Results- Nine young (28+/-1 years old) and 9 older (65+/-1) sedentary and 10 young (2...

BACKGROUND Little is known about the effect maintaining physical activity throughout adolescence has on cardiovascular risk factors and health status in early adulthood. This ten-year prospective longitudinal study investigated whether differences in physical activity patterns from adolescence to young-adulthood showed different associations with subsequent cardio-metabolic risk factors and men...
