Objective To explore the risk factors on cases regarding work-related acute pesticide poisoning among farmers of Jiangsu province.Methods A population-based,1 ∶ 2 matched case-control study was carried out,with 121 patients as case-group paired by 242 persons with same gender,district and age less then difference of 3 years,as controls.Cases were the ones who had suffered from work-related acute pesticide poisoning.A unified questionnaire was used.Data base was established by EpiData 3.1,and SPSS 16.0 was used for both data single factor and multi-conditional logistics regression analysis.Results Results from the single factor logistic regression analysis showed that the related risk factors were:lack of safety guidance,lack of readable labels befores praying pesticides,no regression during application,using hand to wipe sweat,using leaking knapsack,body contaminated during application and continuing to work when feeling ill after the contact of pesticides.Results from multi-conditional logistic regression analysis indicated that the lack of safety guidance (OR=2.25,95％ CI:1.35-3.74),no readable labels befores praying pesticides (OR=1.95,95％ CI:1.19-3.18),wiping the sweat by hand during application (OR=1.97,95％CI:1.20-3.24)and using leaking knapsack during application (OR=1.82,95％ CI:1.10-3.01) were risk factors for the occurrence of work-related acute pesticide poisoning.Conclusion The lack of safety guidance,no readable labels befores praying pesticides,wiping the sweat by hand or using leaking knapsack during application were correlated to the occurrence of work-related acute pesticide poisoning.

Significant contributing causes of cancer deaths among Hispanics in Colorado, USA, 1983-1992

Entre 1983 e 1992, ocorreram 53.921 óbitos por câncer no Estado do Colorado, EUA. Os atestados de óbito para este período foram utilizados para avaliar as causas que contribuíram para a morte e a ocupaçäo principal dos óbitos por câncer ocorridos em latinos neste período. Os riscos relativos para diabetes e doença hepática como causas associadas ao óbito foram significativamente maiores em latinos, comparativamente com näo latinos que também faleceram com câncer (diabetes RR= 1,90; I.C. 95 por cento 1,64-2,19; doença hepática RR=1,44; I.C 95 por cento 1,23-1,68). O consumo de drogas como causa associada à morte entre latinos que faleceram por câncer aparentou ser significativamente menor que em näo latinos (RR=0,69; I.C. 95 por cento 0,52-0,91). Operários, servidores públicos e trabalhadores de escritório de origem latina tenderam a apresentar diabetes e doença hepática como causas associadas à morte por câncer em maior freqüência, estatisticamente significativa, que näo latinos nos mesmos ramos de atividade (p<0,05>. Doenças crônicas, como diabetes e doença hepática, podem estar reduzindo a sobrevida por câncer em latinos.
