Older, hypertensive, and hypercholesterolemic fairgoers visit more booths and differ in their health concerns at a community health fair.

The purpose of this study was to determine whether persons attending a community health fair had different health concerns and booth visitation patterns based on their risk factor profiles. All fairgoers were encouraged to complete an anonymous survey of demographic information, top 4 health concerns, and selected cardiac risk factors. Over the five-hour duration of the fair, 329 surveys were collected from about 450 fairgoers. There were no exclusion criteria for the survey. The fair was sponsored by the Maryland Chapter of the American College of Physicians, organized by medical students from the University of Maryland and Johns Hopkins University, and included 23 booths on a variety of health topics. Older fairgoers and fairgoers with a self-reported history of high blood pressure or elevated cholesterol showed an increased interest in hypertension and heart disease (p < 0.05). Older fairgoers also showed an increased interest in health topics related to aging, such as estrogen replacement therapy and geriatric medicine. Older, hypertensive and hypercholesterolemic fairgoers visited an increased mean number of total booths when compared to other respondents (p < 0.05). Most booths reported a higher percentage of older, hypertensive, and hypercholesterolemic visitors than the overall percentage of fairgoers who reported these risk factors. These results suggest that booth visitation patterns of health fair participants may be viewed as a deliberate attempt by at risk populations to access health information particular to their needs.

Increased hematocrit and decreased transfusion requirements in children given erythropoietin before undergoing craniofacial surgery.

OBJECT: This study was undertaken to determine the efficacy of preoperative erythropoietin administration in infants scheduled for craniofacial surgery and, in so doing, to minimize problems associated with blood transfusions. METHODS: Families were offered the option of having their children receive erythropoietin injections before undergoing craniofacial surgery. The children whose families accepted this option received daily iron and 300 U/kg erythropoietin three times per week for 3 weeks preoperatively. Weekly complete blood counts with reticulocyte counts were measured and transfusion requirements were noted. Blood transfusions were administered depending on the clinical condition of the child. A case-matched control population was also evaluated to compare initial hematocrit levels and transfusion requirements. Thirty patients in the erythropoietin treatment group and 30 control patients were evaluated. The dose of erythropoietin administered was shown to increase hematocrit levels from 35.4 +/- 0.9% to 43.3 +/- 0.9% during the course of therapy. The resulting hematocrit levels in patients treated with erythropoietin at the time of surgery were higher compared with baseline hematocrit levels obtained in control patients at the time of surgery (34.2 +/- 0.5%). Transfusion requirements also differed: all control patients received transfusions, whereas 64% (19 of 30) of erythropoietin-treated patients received transfusions. CONCLUSIONS: The authors conclude that treatment with erythropoietin in otherwise healthy young children will increase hematocrit levels and modify transfusion requirements. Erythropoietin therapy for elective surgery in children of this age must be individualized according to the clinical situation, family and physician beliefs, and cost effectiveness, as evaluated at the individual center.
