RESUMO
Data from the first National Health and Nutrition Examination Survey were examined for individual 24-h dietary intakes of protein, vitamin A, thiamin, riboflavin, and iron, and for laboratory indices of the same nutrients in blood and urine. Mean intake values were close to or above reference standards for all nutrients except iron. Substandard laboratory values were recorded for: serum albumin and vitamin A--less than 3% of subjects; urinary thiamin/creatinine excretion--3 and 8% of white and Black subjects, respectively; Hb, hematocrit, and percentage transferrin saturation--5 to 15% of whites and 18 to 27% of Black subjects; serum iron--less than 6% of subjects. Individual dietary recall data were of limited value in predicting the laboratory indices; regression analyses indicated that sociodemographic variables may be of greater predictive value.

The distribution and characteristics of workplace injuries for West Virginia volunteer fire fighters (VFFs) are described using 1992 workers' compensation data. Most of the injuries occurred in VFFs who were less than 30 years of age (62%). The most common type of injuries were those in the category of lacerations and contusions (28.9%), with a notable percentage of injuries due to smoke inhalation and respiratory problems (13.7%). The proportional rates related to falls in VFFs were almost twice the national figures for the same year (39.3% versus 22.3%). County population density was found to be directly associated with injury rates, even when adjusted for number of responses. Claims statistics mirror a similar geographical trend in overall workers' compensation claims for all injuries in West Virginia. The results of this study provide a foundation for additional follow-up studies in order to develop improved occupational safety policies and target educational programs aimed at the prevention of injuries in volunteer fire fighters. Several findings have already resulted in programmatic recommendations.

Written educational materials and consent forms are often given to patients with little regard for their ability to read them. Nationwide sampling and data from the 1990 census suggest that 10% of U.S. adults are functionally illiterate. In this study, 100 adult patients (64 female, 36 male) seen consecutively in an oncology clinic were tested for reading vocabulary (RD-VOCAB) and reading comprehension (RD-COMP) using the Woodcock-Johnson Psychoeducational Battery. The mean grade levels of education (last grade completed), reading vocabulary, and reading comprehension of all participants were 12.5, 11.3, and 10.5, respectively. The discrepancy between the grade level of education and RD-COMP varied by age, the largest discrepancies being found in the 30-39 (three grades) and 60-69 (2 1/2 grades) age groups. After controlling for educational level, it was found that the mean grade level of RD-COMP was statistically lower than educational level. Statistically assuming all subjects to have completed high school, the mean levels of RD-COMP ranged from ninth grade in the 30-39 age group to twelfth grade in the 40-49 age group. This study underscores the fact that the health professional cannot assume that a patient who has completed a certain grade level in school can read at the corresponding level. Consent forms and other health education materials should be written at least three grade levels lower than the average educational level of the target population.
