Body dissatisfaction among White and African American male and female college students.
Body size perception has been shown to be highly influenced by cultural factors including race. This study assessed body size perceptions of a convenience sample of college students (N=630). Included in a paper-and-pencil survey were current height and weight (body mass index (BMI)=wt [kg]/ht(2) [m]), perceived BMI, desired MI and perceptions of BMIs desired by others. Also assessed were perceptions of underweight, acceptable weight and overweight/obesity. African American females were found to have a higher current BMI than Whites (P< or =.001), higher desired BMI (P< or =.001) and higher BMI perceived to be desired by others (P< or =.001). African American and White males did not differ on any of these measures. Most (83%) underweight (BMI<19) African American females perceived themselves as underweight while only about one-half of underweight (56%) White females perceived themselves as underweight. Almost half (43%) of White females and about a fourth (27%) of African American females of acceptable BMI range (BMI=19-25) desired to be in the underweight range. Of those who were overweight (BMI=25-30), 20% of the Whites and only 3.0% of the African Americans chose an underweight silhouette as being desired. While African Americans and White males tended to have similar perceptions that there remains sociocultural influences in African American females regarding acceptance of a large body size.

Occupational exposure limits for chemicals.
Occupational exposure limits (OELs) are tools to help employers protect the health of those who may be exposed to chemicals in their workplace. Under the United Kingdom Control of Substances Hazardous to Health (COSHH) Regulations they define adequate control by inhalation. OELs are set by the Health and Safety Commission (HSC) on advice from its Advisory Committee on Toxic Substances (ACTS) and after public consultation. Thus they are consensus limits which have the support of both sides of industry. COSHH uses two types of occupational exposure limit-the occupational exposure standard (OES) and the maximum exposure limit (MEL). OESs are set for substances for which it is possible to identify a concentration at which there is no significant risk to health. Employers are required to meet the limit, there is no requirement to go below it, and it can be exceeded provided steps are taken to meet it as soon as reasonably practicable. MELs are set for substances which have serious health implications and for which an OES cannot be set. Most of the substances with MELs are either carcinogens or causes of occupational asthma. Employers must not exceed an MEL and must reduce exposure as far below it as is reasonably practicable. MELs are set at concentrations achievable by good occupational hygiene practice such that risks to workers are judged to be reduced to a tolerable level. The HSC consider that this approach is preferable to the use of mathematical models to generate risk estimates, which inevitably gives a spurious appearance of accuracy. The MEL/OES system is poorly understand by many employers who use chemicals, is not comprehensive as some substances meet neither the OES nor MEL criteria, and does not mesh well with indicative occupational exposure limit values which will increasingly be set under the European Union Chemical Agents Directive. COSHH essentials: easy steps to control chemicals provides the practical help that firms need to control chemicals. It takes users straight from hazard and exposure considerations to benchmark standards of good practice. The problems with the current system have prompted ACTS to set up a subgroup to review the OEL framework.

Racial and gender differences in weight status and dietary practices among college students.
A questionnaire was used to assess nutritional intake, weight status, and dietary practices among 630 U.S. college students. Body mass index (BMI) was calculated using self-reported heights and weights, and nutritional status was assessed via 24-hour recall. Sixty-four percent of the students had acceptable BMI levels (between 19 and 25); 16% of African-American females and 15% of African-American males had BMIs indicating obesity (30 or above). Approximately 18% of the students consumed 5 servings per day of fruits and vegetables, 7% consumed 6 or more grain products, and 53% consumed 2 or more dairy products. Twenty-seven percent reported never/rarely eating fast foods. Recommendations are presented for the development of culturally appropriate health education/promotion programs in order to help college students meet Healthy People 2010 objectives.

A randomized trial of a brief HIV risk reduction counseling intervention for women.
There is an urgent need for the development and implementation of effective and feasible behavioral HIV and STD interventions. The purpose of the present randomized controlled trial was to evaluate the effectiveness of a single-session, skill-based sexual risk reduction intervention for women. Participants were assessed at baseline and at 1 month and 3 months following the intervention on measures of AIDS knowledge, behavioral intentions, self-efficacy, and sexual risk behavior. Compared with women in an AIDS-education-only condition, women receiving the skill-based intervention reported significantly higher rates of condom use at 3-month follow-up. Results suggest that brief sexual risk reduction programs are feasible and effective within a community setting.

Factors relating to the development of respiratory symptoms in coffee process workers.
After several cases of occupational asthma had been reported in a coffee processing factory in England, 197 coffee workers representing 80% of the production workforce were studied to determine the factors affecting the development of work related respiratory symptoms of wheeze, cough, and dyspnoea. Two computer administered questionnaires concerning the presence of respiratory symptoms and the occurrence of work related respiratory symptoms were used. Workers underwent skin prick testing to green coffee bean extract (GCB) and 11 common inhalant allergen extracts and bronchial provocation testing with methacholine. The presence of specific immunoglobulin E (IgE) antibodies to GCB and castor bean extract (CAB) were determined by a radioallergosorbent test (RAST). The prevalence of work related respiratory symptoms was 12.7%, bronchial hyperresponsiveness 30%, atopy 54%, positive GCB skin prick test 14.7%, positive GCB RAST 14%, and positive CAB RAST 14.7%. None of the workers was sensitised to fungi present in the factory and the numbers of certain species of fungi, despite being greater than may be found out of doors or in an uncontaminated indoor environment, were fewer than are generally associated with the presence of work related respiratory symptoms among agricultural workers. Storage mites were not isolated. Green coffee bean extract and CAB RAST were significantly correlated using the McNemar test but there was limited allergenic cross reactivity in RAST inhibition studies of the two extracts. The only factors that were significantly and independently associated with work related symptoms were CAB RAST and duration of employment. Bronchial hyperresponsiveness was not independently associated with work related respiratory symptoms. The significant independent associations of bronchial hyperresponsiveness included GCB RAST, duration of employment, and resting forced expiratory volume in one second. Exposure to CAB, a highly potent antigen, may be overriding the effects of other factors such a GCB, atopy, bronchial hyperresponsiveness, and smoking. This study suggests that CAB contamination remains a potential problem in the coffee processing industry and all efforts to eliminate it from the working environment should continue.

Casualty attendances: one year's experience at Waikato Hospital.
All casualty attendances (25 707) at a general hospital in the year 1979 were reviewed considering sex, age, employment, location of accident, mechanism of accident, diagnosis, time of arrival at casualty, day of week, week, and month. Males, young people (less than 32 years old), and working people were common attenders. Home accidents and weekend visits were frequent. these and other findings are discussed in the context of other recent similar studies.
