Assessing outcomes of industrial hygiene graduate education.

To ensure that industrial hygiene professionals continue to be prepared for current and future trends, it is important to regularly assess the value of their education. Described here are the results of discussions with employers and a mailed survey of graduates. Comparisons are made with past mailed surveys of both groups.

Graduate proficiency assessment using a competency-based learning model.

Objective: The goal of this study was to evaluate and compare occupational health and safety graduates' perceptions of the value of and their proficiency in 29 educational competencies.

Methods: A survey was mailed to 159 students graduating between 1992 and 2005.

Results: Ninety-eight graduates (62% response) ranked all 29 competencies as valuable or very valuable.

Small business owners' opinions about written health and safety information.

Owners of small manufacturing businesses from twelve industrial sectors (n=40) participated in focus groups. They most frequently read trade and local business publications; few regularly read or receive health and safety materials. They select business-related materials that are specific to their business, give them new ideas, or have information that is easy to use.

Asthma, atopy, and lung function among racially diverse, poor inner-urban Minneapolis schoolchildren.

As part of an assessment of schoolchildren's environmental exposures and health, a probability sample of 136 children from diverse racial/ethnic backgrounds was drawn from grades 2-5 of two inner-urban Minneapolis schools (Whittier, Lyndale). Questionnaires were administered to a parent/guardian; blood samples for IgE and lung function tests were obtained. Overall adjusted rates for lifetime asthma (15.

Competencies most valued by employers--Implications for master's-prepared occupational health nurses.

Educational institutions seek to prepare students to compete for positions in the workplace with a competency-based education. Employers are important stakeholders in the preparation of occupational health nurses. Competencies considered most valuable by employers will affect their hiring decisions.

Using biologic markers in blood to assess exposure to multiple environmental chemicals for inner-city children 3-6 years of age.

We assessed concurrent exposure to a mixture of > 50 environmental chemicals by measuring the chemicals or their metabolites in the blood of 43 ethnically diverse children (3-6 years of age) from a socioeconomically disadvantaged neighborhood in Minneapolis. Over a 2-year period, additional samples were collected every 6-12 months from as many children as possible. We analyzed blood samples for 11 volatile organic compounds (VOCs), 2 heavy metals (lead and mercury, 11 organochlorine (OC) pesticides or related compounds, and 30 polychlorinated biphenyl (PCB) congeners.

Indoor air quality in two urban elementary schools--measurements of airborne fungi, carpet allergens, CO2, temperature, and relative humidity.

This article presents measurements of biological contaminants in two elementary schools that serve inner city minority populations. One of the schools is an older building; the other is newer and was designed to minimize indoor air quality problems. Measurements were obtained for airborne fungi, carpet loadings of dust mite allergens, cockroach allergens, cat allergens, and carpet fungi.

Environmental health and nursing: piloting a technology-enhanced distance learning module.

The results of a pilot study evaluating a technology-enhanced distance learning module to impart environmental health core concepts to nurses are presented in this article. The internet-based module was developed for continuing professional education and imparts principles of adult education through interactive features including simulated clinical vignettes, an environmental justice case study, and hyperlinks to websites related to environmental protection and health regulation. Mean gains between pre- and post-tests; participant identification of adult learning principles as advanced by Knowles, Holton, and Swanson (1998); and satisfaction were measured among participating RNs (N = 34).

Crosscutting competencies for occupational health and safety professionals.

A change from a quarter system to a semester system presented a convenient opportunity for faculty at the Midwest Center for Occupational Health and Safety (a 27-year-old National Institute for Occupational Safety and Health-sponsored education and research center) to evaluate the current curriculum. As part of this process faculty identified both individual and crosscutting competencies for four programs: Occupational Medicine, Occupational Health Nursing, Industrial Hygiene, and Occupational Injury Epidemiology and Control. Faculty identified potential competency sets using published literature, course objectives, and content summaries.

Children's exposure to volatile organic compounds as determined by longitudinal measurements in blood.

Blood concentrations of 11 volatile organic compounds (VOCs) were measured up to four times over 2 years in a probability sample of more than 150 children from two poor, minority neighborhoods in Minneapolis, Minnesota. Blood levels of benzene, carbon tetrachloride, trichloroethene, and m-/p-xylene were comparable with those measured in selected adults from the Third National Health and Nutrition Examination Survey (NHANES III), whereas concentrations of ethylbenzene, tetrachloroethylene, toluene, 1,1,1-trichloroethane, and o-xylene were two or more times lower in the children. Blood levels of styrene were more than twice as high, and for about 10% of the children 1,4-dichlorobenzene levels were greater than or equal to 10 times higher compared with NHANES III subjects.

Outdoor, indoor, and personal exposure to VOCs in children.

We measured volatile organic compound (VOC) exposures in multiple locations for a diverse population of children who attended two inner-city schools in Minneapolis, Minnesota. Fifteen common VOCs were measured at four locations: outdoors (O), indoors at school (S), indoors at home (H), and in personal samples (P). Concentrations of most VOCs followed the general pattern O approximately equal to S < P less than or equal to H across the measured microenvironments.

Children's exposure to environmental tobacco smoke: using diverse exposure metrics to document ethnic/racial differences.

Four metrics were used to assess exposure to environmental tobacco smoke (ETS) for a probability sample (n = 152) of elementary school-age children in two economically disadvantaged neighborhoods: a) caregiver responses to a baseline questionnaire (BQ) about smoking status and behavior; b) 48-hr time-activity (T-A) data on location and time spent by children in the presence of tobacco smoke; c) total urinary cotinine as a marker for nicotine uptake; and d) urinary NNAL [4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol] + NNAL-Gluc [4-(methylnitrosamino)-1- (3-pyridyl)-1-(O-beta-D-glucopyranuronosyl)butane] as a marker for uptake of the tobacco-specific lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Consistent differences in ETS exposure by ethnicity and race were observed. Although data were insufficient to determine differences for NNAL + NNAL-Gluc, BQ responses, T-A data, and cotinine levels all indicated that average ETS exposure was highest for African-American children, moderately high for those designated "other" (white, Southeast Asian, Native American), moderately low for Hispanic children, and lowest for Somali immigrant children.

Recruitment, retention, and compliance results from a probability study of children's environmental health in economically disadvantaged neighborhoods.

The School Health Initiative: Environment, Learning, and Disease (SHIELD) study used a probability sample of children (second through fifth grades) from two low-income and racially mixed neighborhoods of Minneapolis, Minnesota, to assess childhood environmental health. Children were eligible to participate in SHIELD regardless of whether they or their families spoke a foreign language, their household had a telephone, or they were enrolled in a special education program. The overall enrollment rate in year 1 was 57%, with a substantial disparity between children from English-speaking (42%) versus non-English-speaking (71%) families.
