CONTEXT Major cardiovascular diseases (CVDs) are leading causes of mortality among US Hispanic and Latino individuals. Comprehensive data are limited regarding the prevalence of CVD risk factors in this population and relations of these traits to socioeconomic status (SES) and acculturation. OBJECTIVES To describe prevalence of major CVD risk factors and(More)
BACKGROUND Prior national surveys capture smoking behaviors of the aggregated U.S. Hispanic/Latino population, possibly obscuring subgroup variation. PURPOSE To describe cigarette use among Hispanic/Latino adults across subgroups of age, gender, national background, SES, birthplace, and degree of acculturation to the dominant U.S. culture. METHODS A(More)
The purpose of this study was to examine characteristics associated with the insulin metabolic syndrome, including insulin resistance, abnormal glucose tolerance, dyslipidemia, obesity, and elevated blood pressure, among women who have experienced gestational diabetes. 39 nondiabetic, young (20-42 years), postpartum (3-18 months) white women were recruited(More)
BACKGROUND This study aimed to determine the association between circulating leptin levels and total depressive symptoms as well as depressive symptom dimensions (cognitive and somatic) after controlling for important confounding factors. METHODS The study sample was comprised of 135 participants with the metabolic syndrome. Depressive symptoms were(More)
Generalizability theory was used to examine the stability of blood pressure (BP) measurement in normotensives and mild hypertensives. Three to six readings at home or at work provided adequate reliability for the same day in each setting. Under structured laboratory conditions, two to three BP measures taken on each of 2 to 3 days for systolic and diastolic(More)
BACKGROUND Sedentary behavior is recognized as a distinct construct from lack of moderate-vigorous physical activity and is associated with deleterious health outcomes. Previous studies have primarily relied on self-reported data, whereas data on the relationship between objectively measured sedentary time and cardiometabolic biomarkers are sparse,(More)
Thirteen conditioned athletes were studied before and 5 min after running 10,000 m. This distance was run in an average of 41±4 min. All runners lost weight and accompanying this weight loss was an increase in the serum osmolality in the six runners in which it was measured. There was a significant increase in serum glucose (96±11 mg-% before run; 170±48(More)
Twelve highly conditioned long-distance runners were studied to determine the effects of marathon (42 km) and 10,000 m running on plasma immunoreactive glucagon (IRG), serum immunoreactive insulin (IRI), and serum glucose (G) levels. Blood samples were drawn just prior to and immediately upon completion of the run. Marathon running resulted in no(More)
Ambulatory blood pressure was studied as a function of posture, place, and mood in 131 subjects classified according to race, gender, and hypertensive status. The effect of posture was significant and explained a substantial proportion of within-subject variability. After controlling for posture, significant place and mood effects were observed when(More)
