Body mass index mediates the association between meat intake and insulin sensitivity.

The purpose of this study was to examine the possible inverse relationship between total meat intake and processed meat intake and insulin sensitivity as mediated by body mass index (BMI). The Quantitative Insulin Sensitivity Check Index (QUICKI) was used to assess participants' insulin sensitivity: decreased insulin sensitivity indicated at a score of <0.36.

Macronutrients Association with Change in Waist and Hip Circumference Over 9 Years.

Objective: The calorie distribution of macronutrients affects individuals' health. Quantity and source of macronutrients may play major roles in waist circumference (WC) and hip circumference (HC). This study's purpose is to investigate the association between the quantity and source of macronutrients and the change in WC and HC over 9 years.

Healthy Eating Index 2005 and selected macronutrients are correlated with improved lung function in humans.

A number of dietary components have been associated with lung function. However, a comprehensive measure of a healthy diet has not been compared with lung function. Herein, we test the hypothesis that a healthy overall diet, as assessed by the Healthy Eating Index 2005 (HEI-2005), will be associated with increased lung function.

DASH-like diets high in protein or monounsaturated fats improve metabolic syndrome and calculated vascular risk.

Weight-loss diets with varying proportions of macronutrients have had varying effects on weight loss, and components of metabolic syndrome and risk factors for vascular diseases. However, little work has examined the effect of weight-neutral dietary changes in macronutrients on these factors. This is an investigation using the OMNI Heart datasets available from the NHLBI BioLINCC program.

Combined fruit and vegetable intake is correlated with improved inflammatory and oxidant status from a cross-sectional study in a community setting.

Previous studies have examined the relationship between specific nutrient and food intakes with limited markers of either inflammation or oxidant status. The objective of this study was to determine if an increase in combined self-reported fruit and vegetable (F&V) intake in a community setting was associated with improved multiple markers of inflammatory and oxidant status. A community group (N = 1000, age 18-85 years, 61% female) gave two fasted blood samples separated by 12 weeks.

Building prediction models for coronary heart disease by synthesizing multiple longitudinal research findings.

Background: No methodology is currently available to allow the combining of individual risk factor information derived from different longitudinal studies for a chronic disease in a multivariate fashion. This paper introduces such a methodology, named Synthesis Analysis, which is essentially a multivariate meta-analytic technique.

Design: The construction and validation of statistical models using available data sets.
