Fat Reduction Intervention Trial in African-Americans

2014-07-23 21:56:32 | BioPortfolio

Summary

To conduct a randomized controlled trial to evaluate the effectiveness of an intervention to reduce dietary fat.

Description

BACKGROUND:

The African-American population of the United States continues to experience high rates of mortality from cardiovascular (CV) disease, including coronary heart disease, stroke and renal failure. The major syndromes which determine CV risk, including obesity, hypercholesterolemia, glucose intolerance, and hypertension, all occur more frequently among African Americans. Nutritional factors underlie many forms of CV disease and are an important focus of current prevention efforts. Very little is currently known, however, about specific nutritional patterns among African Americans that might lead to CV risk, or the applicability of structured interventions.

The study was conducted in response to an initiative on "Collaborative Projects on Minority Health" which was released in October 1992 after review and approval at the September 1992 National Heart, Lung, and Blood Advisory Council.

DESIGN NARRATIVE:

Given the growing recognition of the importance of total fat, from the point of view of both disease risk and eating patterns, the primary focus of the intervention was to reduce the percentage of calories in the diet from fat. Four hundred households were recruited and randomly assigned to either an active intervention or observation group for a period of 18 months. Dietary change consistent with specific recommendations made to the American public for reducing cardiovascular (CV) risk was encouraged, namely, reduction in total fat, saturated fat (SFA), and cholesterol (Chol). A practical, community-based program was developed which could be taken into households. Nutrition education and enhancement of skills helpful in making behavioral change formed the basis of the intervention. Lay educators, recruited from the target neighborhoods, worked under the close supervision of a community nutritionist. Changes in reported dietary intake, serum lipids/lipoproteins and body weights were measured. In addition to the formal evaluation of the trial outcome, an important secondary goal was to obtain detailed information about eating patterns in this community and characterize behavior associated with the achievement and maintenance of target nutrient goals.

The study was part of a collaborative project on minority health. Dr. Prewitt collaborated with Dr. Marian Fitzgibbon who was the principal investigator on R01HL51532.

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.
