Quality control in the Multiple Risk Factor Intervention Trial Nutrition Modality.
TLDR
The MRFIT nutrition intervention program was designed with the need for interclinic comparability of intervention techniques in mind, and required not only development of study-wide nutrition intervention materials, but also necessitated ongoing attention to staff training and monitoring procedures in order to ensure intercenterComparability of efforts.About:

Seven-year trends in body weight and associations with lifestyle and behavioral characteristics in black and white young adults: the CARDIA study.
TL;DR: The observed dramatic time-related weight gains, most likely due to secular (period-related) trends, are a serious public health concern.

TL;DR: Dietary quality control procedures yielded data generally indicative of high quality performance in the four countries, and use of tape recorded dietary interviews contributed to quality control, despite feasibility problems, deemed remediable by protocol modification.
Journal ArticleDOI
Quality Assurance and Quality Control in Longitudinal Studies
TL;DR: The magnitude of the quality control process in a multicenter longitudinal study should not be underestimated, requiring a significant commitment of study resources.

The multiple risk factor intervention trial (MRFIT): IV. Intervention on blood lipids
Arlene W. Caggiula,George Christakis,Marilyn Farrand,Stephen B. Hulley,Ruth Johnson,Norman L. Lasser,Jeremiah Stamler,Graham M. Widdowson +7 more
TL;DR: Comparison with earlier population data suggests that the overall responses to the MRFIT eating pattern were limited by the apparent fact that participants had already made self-initiated changes toward the fatcontrolled dietary pattern before they entered the study.

Assessing dietary adherence in the Multiple Risk Factor Intervention Trial (MRFIT). I. Use of a dietary monitoring tool.
TL;DR: Using special forms supplied by MRFIT nutrition counselors, participants were able to self-monitor their dietary regimens and a food scoring system was developed in which positive points are assigned to high-saturated-fat foods and negative points to foods and high-polyunsaturated-Fat and low-cholesterol content.

TL;DR: Using the dietary methodology which has evolved through NHLBI's ongoing program of research investigations, it appears that the health-conscious men randomized into the MRFIT were already consuming diets somewhat more prudent than those in an earlier generation of studies.
