BACKGROUND Accurate estimates of the risk of transfusion-transmitted infectious disease are essential for monitoring the safety of the blood supply and evaluating the potential effect of new screening tests. We estimated the risk of transmitting the human Immuno-deficiency virus (HIV), the human T-cell lymphotropic virus (HTLV), the hepatitis C virus (HCV),(More)
BACKGROUND A study was designed to estimate relative analytic sensitivity and window-period (WP) closure and to project incremental yield of newer HBsAg tests, pooled-sample NAT, and single-sample NAT, compared to currently licensed HBsAg tests. STUDY DESIGN AND METHODS HBV DNA and HBsAg test results for 23 HBV seroconversion (SC) panels were first(More)
OBJECTIVE The National Heart, Lung, and Blood Institute Growth and Health Study (NGHS) is a 10-year study to investigate the development of obesity in black and white girls during adolescence and its environmental and psychosocial correlates. The purpose of this report was to examine changes in the annual prevalence rates of overweight and obesity in the(More)
CONTEXT Evaluating trends in blood donor infectious disease rates is essential for monitoring blood supply safety and donor screening effectiveness. OBJECTIVE To determine changes over time in blood donor population infection rates of human immunodeficiency virus (HIV), human T-lymphotropic virus (HTLV), hepatitis C virus (HCV), and hepatitis B virus(More)
Human T-lymphotropic virus types I and II (HTLV-I and -II) cause myelopathy; HTLV-I, but not HTLV-II, causes adult T-cell leukemia. Whether HTLV-II is associated with other diseases is unknown. Using survival analysis, we studied medical history data from a prospective cohort of HTLV-I- and HTLV-II-infected and -uninfected blood donors, all HIV(More)
OBJECTIVE Epidemiological studies of eating disorders in the United States have focused on white women and girls, and the prevalence of eating disorders in ethnic minority groups is unknown. This study examined the prevalence of anorexia nervosa, bulimia nervosa, and binge eating disorder in a geographically and economically diverse community sample of(More)
PURPOSE Obesity is assumed to have a negative impact on self-esteem because of the associated social stigmatization in Western society. Studies of the psychological effect of obesity in children are inconclusive and limited, particularly pertaining to minority populations. Most studies have assessed global rather than domain-specific measures of self-esteem(More)
BACKGROUND Understanding blood donor motivations is crucial to improving effectiveness of donor recruitment and retention programs. STUDY DESIGN AND METHODS Data from a 1998 survey of 92,581 U.S. blood donors were used to evaluate factors influencing the decision to donate in various demographic groups. Data were weighted to adjust for response and sample(More)
BACKGROUND Blood donation can be described as a prosocial behavior, and donors often cite prosocial reasons such as altruism, empathy, or social responsibility for their willingness to donate. Previous studies have not quantitatively evaluated these characteristics in donors or examined how they relate to donation frequency. STUDY DESIGN AND METHODS As(More)
BACKGROUND The potential effectiveness of various donation incentive programs may vary by demographics, first-time or repeat status, and collection site. STUDY DESIGN AND METHODS Attitudes toward future incentives were obtained from a 1998 anonymous survey sent to 92,581 US blood donors. Responses (encouraged, discouraged, no difference) to incentives(More)
