OBJECTIVES We examined the association between circumcision status and the prevalence and incidence of gonorrhoea, chlamydia, and syphilis. METHODS We analysed(More)
In 1993, the levels of copper (Cu) in much of Nebraska's drinking water exceeded the U.S. Environmental Protection Agency's (EPA) action level of 1.3 mg/L. To determine the association of copper with gastrointestinal (GI) illness in August 1994 the authors interviewed persons living in households with 1993 Cu levels > 3 mg/L (51 households), 2-3 mg/L (54(More)
The nature and direction of changes in empathy as measured by Hogan's empathy scale was explored over time (1975, 1976, and 1979) for medical students in the class of 1979 at the Bowman Gray School of Medicine. Results indicated that empathy scores declined slightly over time, correlated negatively with Medical College Admission Test scores, and were(More)

Available data also permitted examination of the relationship between selected background characteristics and compliance with follow-up. Noncompliance was defined as failure to respond to notification of an(More)
This study examines the weight-for-height index q = w/h lambda where the parameter lambda is chosen to maximize the correlation of q with triceps skinfold thickness, and thus provide an indirect measure of adiposity. Using a sample of 1668 children ages 5-12 years, we estimate lambda by an iterative procedure in each age/sex category. We find that lambda(More)
This study examines several weight for height indices--Quetelet's index W/H2, W/H, and Rohrer's index W/H3--for their appropriateness in estimating adiposity among young children. Data were obtained for a sample of 1,668 children age 5-12 residing in Forsyth County, North Carolina. Although W/H2 was found to be the most useful of these indices, the results(More)
