OBJECTIVES The phenomenon of grandparents caring for grandchildren is disproportionately observed among different racial/ethnic groups in the United States. This study examines the influence of childcare provision on older adults' health trajectories in the United States with a particular focus on racial/ethnic differentials. METHOD Analyzing nationally representative, longitudinal data on gr...

Compliance and distensibility are wall properties of large arteries, which may play a role in cardiovascular disease. The purpose of this study was to investigate whether the influence of age on these vessel wall properties differs between vascular territories and is gender-dependent. In a population sample of 498 men and women 20 to 79 years of age, diameter, distensibility, and compliance coe...

OBJECTIVES To determine the value of ankle and toe blood pressure indices and pedal pulse palpation in the assessment of peripheral arterial disease in subjects with type 2 diabetes mellitus (DM). DESIGN Cross-sectional study. SUBJECTS A convenience sample of 85 female subjects with type 2 DM underwent a series of peripheral vascular assessments at the diabetes clinic of a community hospita...

AIM Whole-body vibration exercise (WBV) acutely decreases brachial-ankle pulse wave velocity (baPWV), an index of systemic arterial stiffness. However, the effect of WBV on segmental PWV and aortic hemodynamics is unknown. We examined the acute effects of WBV on arterial function. METHODS Fifteen young men performed ten 1-min sets of static squat with WBV (40 Hz, 1 mm, 5.37 G) and without WBV...

OBJECTIVE Under physiological conditions, arteries remodel in response to changes in blood flow to maintain local shear stress. Risk factors and developing atherosclerosis may be associated with maladaptive remodeling that produces relatively large arteries with low levels of shear stress. Recent studies have shown that the brachial artery and other peripheral arteries are enlarged in patients ...
