Case-control study of student-perpetrated physical violence against educators.

Purpose: Although prior research focused primarily on student-on-student school violence, educators are also at risk. This study was designed to identify risk factors for assaults against educators.

Methods: Kindergarten-grade 12 educators (n = 26,000), randomly selected from a state license database, were screened for eligibility (6,469, eligible) by mailed questionnaire.

Violence against educators: a population-based study.

Objective: Identify the magnitude and risk factors for occupational physical assault (PA) and nonphysical violence (NPV) against Minnesota educators.

Methods: Among 26,000 randomly selected licensed kindergarten to grade 12 educators, 6469 eligible educators reported whether they experienced PA or NPV during the prior year. Multiple logistic regression models were based on directed acyclic graphs.

Recruitment methods employed in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

Background: The Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO) is a US National Cancer Institute (NCI)-funded randomized controlled trial designed to evaluate whether certain screening tests reduce mortality from prostate, lung, colorectal, and ovarian cancer. To obtain adequate statistical power, it was necessary to enroll over 150,000 healthy volunteers. Recruitment began in 1993 and ended in 2001.

Difference in work-related violence by nurse license type.

Nurses are at considerable risk for work-related violence. This study compared the experiences of work-related violence among registered nurses (RNs) and licensed practical nurses (LPNs) to quantify differences in risks and exposures and to gain insight into possible interventions. A random sample (n = 6,300) of licensed Minnesota nurses was surveyed regarding the previous 12-month period.

Risk factors for work-related assaults on nurses.

Background: Work-related homicides have been the subject of considerable study, but little is known about nonfatal violence and relevant risk factors.

Methods: We surveyed 6300 Minnesota nurses who were selected randomly from the 1998 licensing database and determined their employment and occupational violence experience. In a nested case-control study, we examined environmental exposures and physical assault.

A randomized trial of direct mailing of fecal occult blood tests to increase colorectal cancer screening.

Background: Although colorectal cancer screening by using a fecal occult blood test (FOBT), flexible sigmoidoscopy, colonoscopy, or barium enema x-ray reduces the incidence of and death from colorectal cancer, the rate of colorectal cancer screening in the general population is low. We conducted a randomized trial consisting of direct mailing of FOBT kits to increase colorectal cancer screening among residents of Wright County, Minnesota, a community in which colorectal cancer screening was promoted.

Methods: At baseline, we mailed a questionnaire about colorectal cancer screening to a random sample of Wright County residents aged 50 years or older who were randomly selected from the Minnesota State Driver's License and Identification Card database (estimated N = 1451).

Colorectal cancer screening adherence in a general population.

Background: This article describes the self-reported colorectal cancer (CRC) screening adherence rates of adults, aged 50 years and older, living in five nonurban Minnesota counties.

Methods: During the year 2000, 1693 eligible respondents, aged 50 years and older, from a randomly selected sample completed a survey assessing CRC screening adherence (approximately 86.3% response).
