Occupational health survey of farm workers by camp health aides.

Little is known about the magnitude of occupational health problems among migrant farm workers. A community-based cross-sectional survey was conducted in two migrant farm worker communities: Homestead, Florida, and Kankakee, Illinois. Camp Health Aides (CHAs) interviewed 425 workers about job tasks, personal protective equipment (PPE), field sanitation, work exposures, and selected health conditions. Limited provision of personal protective equipment was reported among those reporting early re-entry tasks: 35% in Kankakee and 42% in Homestead were provided gloves, and 22% in Homestead and 0% in Kankakee were provided protective clothing. About two-thirds were provided toilet facilities and water for hand-washing. Workers reported high prevalences of health conditions consistent with exposure to ergonomic hazards and pesticides. The prevalence of back pain in the past 12 months was 39% in Homestead and 24% in Kankakee. Among Homestead participants, 35% experienced eye symptoms, while 31% reported skin symptoms. These symptoms were less prevalent among Kankakee participants (16% for both eye and skin symptoms). Specific areas of concern included back pain associated with heavy lifting and ladder work; eye and skin irritation associated with fertilizer application tasks and with working in fields during or after spraying of chemicals, especially early re-entry of sprayed fields; and skin irritation associated with a lack of access to hand-washing facilities. In both Kankakee and Homestead, better adherence to safety standards is needed, as well as greater efforts to implement solutions that are available to help prevent work-related musculoskeletal problems.

Changes in empowerment: effects of participation in a lay health promotion program.

The Camp Health Aide Program is a lay health promotion program for migrant and seasonal farmworkers. The program increases access to health care while facilitating leadership development and empowerment of individual farmworkers through training and experience as lay health promoters (camp health aides [CHAs]). This article describes a study which documents impacts on the CHAs of working as lay health promoters in terms of changes in personal empowerment. The authors developed a working definition of personal empowerment and interviewed 27 CHAs at three program sites (Arizona, New Jersey, and Florida) at three different times. CHAs are grouped in five descriptive categories reflecting varying degrees of change in empowerment over this period. Of the total group of 27 CHAs, 24 exhibited some increase in personal empowerment during the study period. These changes are described in detail, and implications are discussed.

Prospective randomised double-blind trial of the in vivo use of recombinant human erythropoietin in bone marrow transplantation from HLA-identical sibling donors. The Australian Bone Marrow Transplant Study Group.

Ninety one patients between the ages of 17 and 58 years undergoing histocompatible allogeneic transplants from sibling donors were entered into a double-blind randomised trial to evaluate the effect of human erythropoietin (rhu EPO) at a dose of 300 units per kg/day given thrice weekly by intravenous injection on erythropoiesis and on erythrocyte and platelet transfusion requirements. Dose was ceased when the haemoglobin exceeded 12g/dL and recommenced if the haemoglobin fell below 12 g/dL, at 150 units/kg/day. If the haemoglobin exceeded 12 g/dL on a further occasion, the dose of rhu EPO was not given. Patients received two units of erythrocytes when the haemoglobin dropped below 8.5g/dL and received platelet transfusions when the count dropped below 20 x 10(9)/L. Univariate analysis revealed a significantly higher reticulocyte count, haemoglobin concentration and bone marrow erythropoiesis after day 14 in the group receiving rhu EPO but this was not reflected in decreased erythrocyte transfusion (7 +/- 5 in controls versus 6 +/- 5 in rhu EPO group) or in platelet transfusions (11 +/- 7 in controls versus 11 +/- 9 in rhu EPO group). Hospitalisation in each group was the same (29 +/- 8 in the control group and 28 +/- 8 in the rhu EPO group). However, in the multivariate analysis, the administration of rhu EPO was associated with an 18% reduction in erythrocyte transfusion requirement when other variables were taken into account. No side-effects due to rhu EPO were detected in this study.(ABSTRACT TRUNCATED AT 250 WORDS)
