Dietary Patterns and Risk of Cardiovascular Disease

2014-08-27 03:57:46 | BioPortfolio

Summary

To study, prospectively, the association between dietary patterns and risk of coronary heart disease (CHD), ischemic stroke, and hemorrhagic stroke in cohort studies of 121,700 women age 30 to 55 years at baseline in 1976 (the Nurses; Health Study; NHS) and 51,529 men aged 40-75 years at baseline in 1986 (the Health Professionals Follow-up Study; HPFS).

Description

DESIGN NARRATIVE:

In the first five years of the study analyses were performed on food consumption data collected through semiquantitative food frequency questionnaires at baseline and during follow-up in the Nurses Health Study and Health Professionals Follow-up Study cohorts. Dietary patterns were derived from the food consumption data using factor analysis, cluster analysis, and dietary indexes (based on prevailing dietary recommendations). In addition, using existing datasets from dietary validation studies in sub-samples of the two cohorts, the reproducibility and validity of dietary patterns defined by factor/cluster analysis and dietary indexes were evaluated. Further, using prospectively collected and stored bloods in the NHS (n-32,826) during 1989-1990 and the HPFS (n-18,000) during 1993-1994, the investigators examined whether observed associations between dietary patterns and CHD were explained by (or mediated through) plasma biochemical measurements (including serum lipids, thrombotic factors, antioxidants, fasting insulin, and homocysteine levels) in a nested case-control design; and they assessed prospectively the relationship between dietary patterns and these biomarkers in the control samples.

The study was renewed in 2005 to apply novel statistical methods (such as confirmatory factor analysis and structural equation modeling) to validate various dietary patterns and examine their associations with risk of type 2 diabetes, cardiovascular disease and total mortality in two large ongoing cohort studies, the Nurses' Health Study (n=121,700) and Health Professionals' Follow-up Study (n=51,529). In addition to evaluating prevailing dietary recommendations, the study will also examine the role of the Mediterranean-type dietary pattern, the Dietary Approaches to Stop Hypertension (DASH) dietary pattern, and the Atkins-type diet in predicting health outcomes. Using repeated measurements of diet, the study will examine the impact of changes in eating patterns and diet quality over time on subsequent risk of diabetes, CVD, and total mortality. In addition, it will examine relationships between major dietary patterns and novel plasma biomarkers of inflammation and endothelial function and whether such relationships are mediated through obesity. Finally, the study will test interactions between dietary patterns and individual single nucleotide polymorphisms (SNPs) and haplotypes of several promising candidate genes in the inflammation and endothelial dysfunction pathway on risk of coronary heart disease, including PPARa, PPARy, Adiponectin (AdipoQ), PON1, IL-6, TNF-a, ICAM-1, VCAM-1, E-Selectin, NOS3, ACE gene, and angiotensinogen (ANG) genes.

Medical and Biotech [MESH] Definitions

Pathological conditions involving the CARDIOVASCULAR SYSTEM including the HEART; the BLOOD VESSELS; or the PERICARDIUM.

Methods and procedures for the diagnosis of diseases or dysfunction of the cardiovascular system or its organs or demonstration of their physiological processes.

Diseases of long duration and generally slow progression. The four main types of noncommunicable diseases are CARDIOVASCULAR DISEASES (e.g., heart attacks and stroke), CANCER, chronic respiratory diseases (e.g., CHRONIC OBSTRUCTIVE PULMONARY DISEASE and ASTHMA) and DIABETES MELLITUS.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)

Dental care for patients with chronic diseases. These diseases include chronic cardiovascular, endocrinologic, hematologic, immunologic, neoplastic, and renal diseases. The concept does not include dental care for the mentally or physically disabled which is DENTAL CARE FOR DISABLED.
