“…Recientemente, en un estudio realizado con trabajadores en invernaderos, en Polonia, se observó que las mujeres con carga física superior a 1.000 kcal por turno tienen hijos con menor peso al nacer, en comparación con quienes tienen cargas laborales con menor carga física, y que los plaguicidas no muestran este mismo efecto (24). Nuestra sugerencia, basada en el principio de precaución, es que los programas de salud ocupacional de las empresas floricultoras deberían incluir políticas que permitan identificar a las mujeres que buscan una concepción y las embarazadas, con el fin de retirarlas de los invernaderos, donde se juntan varios factores de riesgo que pueden actuar sinérgicamente incrementando el riesgo de presencia de abortos y malformaciones congénitas.…”

Introducción. Los trabajadores en la floricultura están expuestos a plaguicidas y otros factores de riesgo. Se sospecha que el trabajo en estos ambientes ocupacionales está asociado con resultados adversos en la procreación. Sin embargo, los estudios epidemiológicos en Colombia, el país de América Latina con más vieja tradición con estos cultivos, no son consistentes ni concluyentes. Objetivo. Cuantificar la relación entre el trabajo de las mujeres en la floricultura colombiana con la aparición de abortos espontáneos, partos prematuros y malformaciones congénitas, usando los resultados de dos estudios previos. Materiales y métodos. Mediante técnicas de metanálisis se resumieron los resultados de dos estudios con poblaciones trabajadoras en la floricultura colombiana. Se llevó a cabo una evaluación crítica de cada uno de los estudios para identificar los potenciales sesgos y limitaciones metodológicas. Resultados. El estimador agregado para abortos espontáneos fue de 2,24 (IC95%: 1,87-2,68), para prematuros fue de 1,49 (IC95%: 0,91-2,43) y para malformaciones congénitas de 1,31 (IC95%: 1,05-1,64). Conclusiones. Los análisis sugieren que el trabajo en la floricultura se asocia con una mayor aparición de abortos espontáneos y malformaciones congénitas. Sin embargo, no hay indicios de que estos efectos estén asociados con la exposición a plaguicidas. Otros factores de riesgo que requieren posterior estudio son la actividad física y el calor dentro de los invernaderos, ambos presentes en las empresas floricultoras. La evidencia de los países que han entrado recientemente a la industria, ayudará a dilucidar esta relación.Palabras clave: plaguicidas/efectos adversos, agricultura, aborto espontáneo, prematuro, metanálisis, Colombia. Adverse reproductive outcomes among women working in Colombian floriculture: a summary of the evidence through metaanalysisIntroduction. Workers in floriculture are exposed to pesticides and other risk factors. Work in these occupational environments is suspected to be associated with adverse reproductive outcomes. However, epidemiological studies in Colombia, a country that has a long tradition with this occupation, have not been consistent or conclusive. Objective. To quantify the effect of women's work in Colombian floriculture in the occurrence of spontaneous abortion, prematurity, and birth defects, using the results of two previous studies. Material and methods. The results of two previous studies among Colombian floriculture worker populations were summarized with metaanalysis techniques. A critical evaluation of each of the studies identified potential biases and methodological limitations. Results. The pooled estimator of spontaneous abortion was 2.24 (95CI: 1.87-2.68); that of premature infant birth was 1.49 (95%CI: 0.91-2.43), and of birth defects 1.31 (95%CI: 1.95-1.64). Conclusions. The analyses suggested that work in floriculture is associated with a higher occurrence of spontaneous abortion and birth defects. However, these effects are not necessarily associated with pesticide...

Aim This study reviews the evidence on the association between working in greenhouses and the occurrence of muscelosckeletal, reproductive and respiratory disorders, dermal effects, cancer and neurobehavioral effects. Subjects and methods PUBMED, MEDLINE and EBSCO literature bases were searched to identify epidemiological studies conducted over 1996-2006 that focused on the health outcomes of greenhouse workers. Three exclusion criteria were used to limit the selection to studies with quantitative assessment of the association between workrelated risk factors and health disorders: lack of data on work-related risk factors, lack of a suitable risk estimate for work-related risk factors or of sufficient information that allowed calculation of a risk estimate and serious methodological concerns in relation to the purpose of this review (strong selection bias, very low response rate, recall bias). Results The analysis indicates that greenhouse exposure is associated with an increased risk of respiratory disorders, sensitization to allergens and skin reactions. Exposure to dust, bacteria, allergens, fungi and gases may cause or exacerbate asthma, asthma-like syndrome, mucous membrane irritation, chronic bronchitis and dermatitis. The results of the review showed that male workers employed in greenhouse horticulture for more than 10 years had a decreased median sperm concentration. The data on the effect of working in greenhouses on the time to pregnancy are unequivocal, but most of them indicate a relationship between a decreased fecundability ratio and greenhouse work, this referring mostly to pesticide exposure. There are also some indications that greenhouse work may contribute to musculoskeletal and neurobehavioral disorders, but only a few epidemiological studies have corroborated these

“…Results indicate that infants of mothers performing heavy work inside greenhouse during pregnancy had lower mean birth weight than infants of mothers working out of greenhouse. No similar effects of current exposure to pesticides was observed (Jurewicz et al, 2005). A study of the effects of thiocarbamates and carbaryl in 3984 pregnant women in Canada found a higher risk of spontaneous abortion; the increase in risk was less evident for pregestational exposure to phenoxy acetic acid and triazine herbicides, and late spontaneous abortion was associated with the use of fungicides, thiocarbamates and glyphosate (Arbuckle et al, 2001).…”

Exposure to pesticides and heavy work in greenhouses during pregnancy: does it effect birth weight?

Abstract: Our results indicate that infants of mothers performing heavy work inside greenhouse during pregnancy had lower mean birth weight than infants of mothers working out of greenhouse. No similar effects of current exposure to pesticides was observed.
