Abstract

This study investigated the effects of iron supplementation (18 mg per day) on the serum iron, total iron binding capacity (TIBC), hemoglobin levels, and percent hemoglobin saturation with iron of female college basketball athletes. The serum iron and hemoglobin levels of ten varsity basketball athletes and seven control subjects (nonathletes) were measured (pretest) prior to the basketball season and again at the end of the season. Iron supplements, no supplements, or a placebo tablet were given during the 4-month experimental period. ANOVA statistical analyses revealed that the iron supplementation was of no value in raising serum iron, TIBC, percent saturation, and hemoglobin levels and that a 4-month basketball training regimen and season did not significantly lower serum iron and hemoglobin levels.  相似文献

OBJECTIVE: The prevalence of childhood sexual abuse among Latino adult men who have sex with men who live in the US was estimated because a history of childhood sexual abuse increases HIV sexual risk behaviors and other negative health outcomes in adulthood. METHOD: The Urban Men's Health Study is a random-digit telephone probability survey of 2881 adult men who have sex with men (MSM) aged 18 years or older residing in San Francisco, New York, Los Angeles, and Chicago. Self-reported history of childhood sexual abuse was the main outcome measure gathered from 2692 MSM. RESULTS: A significantly higher proportion of Latino MSM reported sexual abuse before age 13 (22%) than did non-Latino MSM (11%). CONCLUSIONS: Latino MSM are twice as likely to report a history of childhood sexual abuse than are non-Latino MSM. Given the association between childhood sexual abuse and increased risk for HIV and other negative health outcomes, health providers must remain vigilant to the possibility of childhood sexual abuse histories among their Latino patients.  相似文献

ABSTRACT

On June 3–5, 2008, international organizations and heads of state met in Rome to discuss the critical situation in global food supplies and prices during the World Food Crisis Summit. The intent of this column is to provide approaches to identifying the complex issues that impact public health, public safety, and nutrition on a global basis. The Web sites selected provide a background for the complex issues involved (energy, climate and environment, agriculture, and politics) and reveal controversial and competing agendas with many far-reaching implications.  相似文献

This chapter addresses the origin, legacy, and persistence of intelligence testing in the United States as a process whereby education was colonized by the field of psychology. The convergence of events which fostered the development of intelligence tests and which maintain them in high standing link the history of schooling to the larger field of social change and reinforce the idea that schools are inseparable from the social climate of which they are a product. Intelligent tests were created as, and are, efficient sorting mechanisms in schools that reflect dominant values and contribute to social stability by justifying unequal educational outcomes as a natural and objective process. In spite of their seemingly meritocratic potential, intelligence tests are a primary mechanism for the reproductive role of schooling in society as reinforcing class, race, and ethnic biases.  相似文献
