A data-based approach to diet questionnaire design and testing.
A self-administered diet history questionnaire has been developed for epidemiologic and clinical use and yielded correlations of r greater than 0.70 with the more detailed method, which produced mean values comparable to national data. Expand
A Reduced Dietary Questionnaire: Development and Validation
A reduced questionnaire was developed by successively omitting segments of the full (98-item) Block questionnaire and calculating the correlations between nutrient estimates produced by the full andExpand
A malnutrition-inflammation score is correlated with morbidity and mortality in maintenance hemodialysis patients.
The MIS appears to be a comprehensive scoring system with significant associations with prospective hospitalization and mortality, as well as measures of nutrition, inflammation, and anemia in MHD patients, and may be superior to the conventional SGA and the DMS as a predictor of dialysis outcome and an indicator of MICS. Expand
Malnutrition-inflammation complex syndrome in dialysis patients: causes and consequences.
Because MICS leads to a low body mass index, hypocholesterolemia, hypocreatininemia, and hypohomocysteinemia, a "reverse epidemiology" of cardiovascular risks can occur in dialysis patients, obesity, hypercholesterolesmia, and increased blood levels of creatinine and homocysteine appear to be protective and paradoxically associated with a better outcome.

A rapid food screener to assess fat and fruit and vegetable intake.
This screener could identify persons with high percentages of calories from fat, total fat, saturated fat, or cholesterol, and persons with low intakes of vitamin C, fiber, or potassium, and is a useful tool for quickly monitoring patients' diets. Expand
The Effect of Breakfast Type on Total Daily Energy Intake and Body Mass Index: Results from the Third National Health and Nutrition Examination Survey (NHANES III)
Eating cereal (ready-to-eat or cooked cereal) or quick breads for breakfast is associated with significantly lower body mass index compared to skipping breakfast or eating meats and/or eggs for breakfast, providing evidence that skipping breakfast is not an effective way to manage weight. Expand
Fruit, vegetables, and cancer prevention: a review of the epidemiological evidence.
It would appear that major public health benefits could be achieved by substantially increasing consumption of fruit and vegetable consumption, and in particular in cancers of the esophagus, oral cavity, and larynx, for which 28 of 29 studies were significant. Expand
Validation of a self-administered diet history questionnaire using multiple diet records.
The validity of a self-administered diet history questionnaire has been estimated using as the reference data the mean of three 4-day diet records collected over the year prior to the administration of the questionnaire, in 1985-1986, using participants in the Women's Health Trial Feasibility Study.

Association among SF36 quality of life measures and nutrition, hospitalization, and mortality in hemodialysis.
In patients on MHD the SF36 appears to have significant associations with measures of nutritional status, anemia, and clinical outcomes, including prospective hospitalization and mortality, even though obesity, unlike undernutrition, is not generally an indicator of poor outcome in MHD. Expand
