Determinants of disability in illnesses related to agricultural use of organophosphates (OPs) in California

Ocular health assessment of cocoa farmers in a rural community in Ghana

Cocoa farming provides employment for over 800,000 households in rural Ghana, with the country currently touted as the second largest producer of cocoa worldwide. Agriculture is one of the riskiest occupations for the eyes due to the numerous ocular hazards on farms. The authors conducted an ocular health assessment among cocoa farmers at Mfuom, a rural community in the Central Region of Ghana, to examine the ocular health status and the ocular safety measures used by cocoa farmers. A structured questionnaire was used to evaluate demographic characteristics, ocular injuries, and utilization of eye care services and ocular protection, and a clinical examination was used to evaluate their ocular status. Cocoa farmers were at high risk for ocular injuries and farm-related vision disorders and utilized eye care services and ocular protection poorly. Ocular condition identified were mainly refractive error (28.6%), cataract (20.0%), glaucoma (11.7%), conjunctivitis (13%), pterygium (2.7%), and cornea opacity (2.2%). There is a need for the introduction of an interventional eye care program to help address the ocular health challenges identified among the farmers. This can be done through collaborative efforts by educational institutions, government, and other role players in the agricultural industry to improve the quality of life of the vulnerable cocoa farmers in rural Ghana.

Eye health and safety among Latino farmworkers

Farmworkers face a variety of risk factors for eye injuries. Measures of eye protection use and of eye safety knowledge and beliefs are based on a survey of 300 Latino farmworkers in North Carolina. Few farmworkers report using eye protection (8.3%); most (92.3%) report that employers do not provide eye protection. Approximately 70% report that they are not trained in preventing eye injuries; 81% believe that their chances of getting an eye injury are low. Many farmworkers choose to take risks in order to save time. Interventions are needed that target farmworker knowledge and beliefs about eye safety.

Pediatric acute lymphoblastic leukemia and exposure to pesticides

Organophosphates are pesticides ubiquitous in the environment and have been hypothesized as one of the risk factors for acute lymphoblastic leukemia (ALL). In this study, we evaluated the associations of pesticide exposure in a residential environment with the risk for pediatric ALL. This is a case-control study of children newly diagnosed with ALL, and their mothers (n = 41 child-mother pairs) recruited from Georgetown University Medical Center and Children's National Medical Center in Washington, DC, between January 2005 and January 2008. Cases and controls were matched for age, sex, and county of residence. Environmental exposures were determined by questionnaire and by urinalysis of pesticide metabolites using isotope dilution gas chromatography-high-resolution mass spectrometry. We found that more case mothers (33%) than controls (14%) reported using insecticides in the home (P < 0.02). Other environmental exposures to toxic substances were not significantly associated with the risk of ALL. Pesticide levels were higher in cases than in controls (P < 0.05). Statistically significant differences were found between children with ALL and controls for the organophosphate metabolites diethylthiophosphate (P < 0.03) and diethyldithiophosphate (P < 0.05). The association of ALL risk with pesticide exposure merits further studies to confirm the association.

Environmental determinants of participation in tourism and recreation of people with varying degrees of disability

Environmental determinants for participation of disabled subjects in tourism and recreation comprise an important social problem. The amount and use of free time for individuals with disabilities in daily life, holidays, and vacation leave and the location for tourism and recreation were examined. Seven hundred and fifty individuals, aged 16-75 yr, with varying degrees of disability, from three eastern provinces of Poland: Podlaskie, Lubelskie and Podkarpackie were investigated. In these studies, a diagnostic survey method with the use of questionnaire, interviews, and analysis of data was carried out. It was found that individuals with disabilities have a significant amount of free time, which is usually spent with family and friends. Among the specific benefits of participation in physical activities are well-being, health improvement, and making new acquaintances. The main factors determining participation in tourism and recreation were price, a friendly group, and doctor recommendations.
