Condom Availability In New York City Public High Schools: Relationships To Condom Use And Sexual Behavior, Sally Guttmacher, Lisa D. Lieberman, David Ward, Nick Freudenberg, Alice Radosh, Don Des Jarlais

Department of Public Health Scholarship and Creative Works

OBJECTIVES: This study examines the impact of the condom availability program in New York City public high schools by comparing rates of sexual activity and condom use for New York students and similar students in Chicago. METHODS: A total of 7119 students from 12 randomly selected New York schools and 5738 students from 10 Chicago schools participated in a cross-sectional survey. RESULTS: New York students, compared with Chicago students, reported equal rates of sexual activity but higher rates of condom use at last intercourse (odds ratio [OR] = 1.36). For higher-risk students (those with three or more sexual partners in …

Environmental Risk Factors And Cancer In The Charleston Heart Study, Vicki Bishop Benard Jan 1997

Environmental Risk Factors And Cancer In The Charleston Heart Study, Vicki Bishop Benard

MUSC Theses and Dissertations

Existing research suggests that a variety of environmental factors play an important role in cancer mortality. The association between some of these factors and cancer mortality was examined using data from the Charleston Heart Study, a thirty-five year prospective cohort. Baseline measurements for tobacco use, place of residence, occupation, education, water supply and physical activity were made in 1960/63 on 2,283 participants. The vital status of the cohort was ascertained through 1994, and the underlying cause of death as determined by the nosologist was used to define cancer mortality. There were 294 cancer deaths identified over the 35-year period. Statistical …

Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg Jan 1997

Parasite Biodiversity And Emerging Pathogens: A Role For Systematics In Limiting Impacts On Genetic Resources, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Emergence of pathogenic organisms continues as a threat to overall biodiversity and genetic resources. Macroparasites including helminths constitute a potential threat to economically important resources in agriculture and conservation biology. Limitation of this threat can be achieved through survey and inventory for biodiversity and the application of systematics to understand the host range , biogeography and history of faunas. Systematics constitutes the foundation for recognition of endemic and introduced elements of faunas and the basis for predicting the behavior of pathogens introduced to new ecological settings or host groups. The basis for emergence of pathogens has both a deep historical …
