BACKGROUND To provide a detailed description of young adults' sedentary time and physical activity. METHODS 384 young women and 389 young men aged 22.1 ± 0.6 years, all participants in the 22 year old follow-up of the Raine Study pregnancy cohort, wore Actigraph GT3X+ monitors on the hip for 24 h/day over a one-week period for at least one 'valid' day (≥10 h of waking wear time). Each minute ...

Regional cerebral blood flow (rCBF) was measured using H2(15)O and positron emission tomography (PET) to test the hypothesis that age-related changes in the pattern of rCBF activation would be greater under divided attention conditions than under selective attention conditions. Subjects were 24 right-handed men: 12 young adults (age 21-28 years), and 12 older adults (age 60-77 years). Measureme...

background: an increase in cardiovascular disease (cvd) frequency was observed over the past three decades in low- and middle income countries, especially in iran. the purpose of the present study was to review and compare the frequencies of conventional and some non-conventional cvd risk factors between men and women in a tertiary level referral cardiovascular teaching hospital in a six month ...

In the Tecumseh study population examined from 1967 through 1969, 1457 men and 1607 women were separated into young (20-39 years), middle (40-54 years), and old (past 55 years) age categories. A subset of the study population, 183 men and 200 women who were repeatedly hyperglycemic according to a modified glucose tolerance test, were divided into the same age groups. Means and standard deviatio...

The criteria proposed for the clinical diagnosis of Takayasu's disease (chronic inflammatory arteriopathy of unknown origin) were based on clinical and angiographic data from 108 Japanese patients: 96 with Takayasu's disease and 12 with another disease of the aorta. The criteria consist of one obligatory criterion (age less than or equal to 40 years), two major criteria (left and right mid subc...

Retirement-related concepts are treated as random variables within Markov process models that capture multiple labor force entries and exits. The expected number of years spent outside of the labor force, expected years in retirement, and expected age at retirement are computed-all of which are of immense policy interest but have been heretofore reported with less precisely measured proxies. Ex...

ET (endothelin)-1, a potent vasoconstrictor peptide released by the endothelium, plays an important role in vasomotor regulation and has been linked to diminished endothelial vasodilator capacity in several pathologies associated with human aging, including hypertension, Type 2 diabetes and coronary artery disease. However, it is currently unknown whether the decline in endothelial vasodilatati...

Pathology laboratories in nine cooperating centers collected arteries from 1532 persons 15 through 34 years of age who died of external causes, principally homicides, accidents, and suicides. A central laboratory stained the arteries and evaluated the atherosclerotic lesions. All of the aortas and about half of the right coronary arteries in the youngest age group (15 through 19 years) had lesi...
