Cardiovascular reactivity and cardiometabolic risk in adolescents.

Background: Cardiovascular reactivity has been examined as a risk marker or factor in the pathogenesis of hypertension or cardiovascular disease, but few have examined the relationship with the metabolic syndrome.

Purpose: We examined whether cardiovascular reactivity to laboratory stress is associated with individual cardiometabolic risk factors and their co-occurrence. A significant positive relationship was hypothesized for both individual and clustered risk factors in their cross-sectional associations with reactivity to multiple stressors.

Cardiometabolic risk in adolescents: associations with physical activity, fitness, and sleep.

Background: Physical activity and fitness are independently associated with cardiometabolic dysfunction, and short sleep duration is an emerging marker of obesity. Few have examined interrelations among these factors in a comprehensive risk model.

Purpose: Investigate the influence of behavioral and lifestyle risk factors on the metabolic syndrome and inflammation.

The prospective contribution of hostility characteristics to high fasting glucose levels: the moderating role of marital status.

Objective: To assess whether psychological constructs of hostility, anger, type A behavior pattern, and depressive symptom severity 1) were associated with concurrent and prospective fasting glucose levels and 2) whether this association was moderated by marital status.

Research Design And Methods: Participants were 485 healthy men ([mean +/- SD] age 59 +/- 7 years) without a history of heart disease, diabetes, or taking related medications in the Veterans Affairs Normative Aging Study. Their fasting glucose levels between 1986 and 1995 were examined.
