Objectives: This longitudinal study measured the glyphosate and paraquat concentrations found in maternal and umbilical cord serum in 82 pregnant women who gave birth in three provinces of Thailand. Methods: Through questionnaires and biological samples collected at childbirth, factors such as personal characteristics, family members occupation, agricultural activities, and herbicide use in agricultural work were evaluated as predictors of glyphosate and paraquat levels in the pregnant women. Statistical analysis used univariate and binary multiple logistic regression, where the outcome was the probability of exposure to paraquat or glyphosate above the limit of detection associated with occupation and household factors. Results: The glyphosate concentrations in the pregnant women’s serum at childbirth (median: 17.5, range: 0.2–189.1 ng/mL) were significantly higher (P < .007) than those in the umbilical cord serum (median: 0.2, range: 0.2–94.9 ng/mL). However, the paraquat concentrations in the serum of the pregnant women at childbirth (83% ≤limit of detection [LOD], with maximum of 58.3 ng/mL) were similar to those in the umbilical cord serum (80% <LOD, with maximum of 47.6 ng/mL). Women with glyphosate levels >LOD in serum at childbirth were 11.9 times more likely to report work as an agriculturist (P < .001), 3.7 times more likely to live near agricultural areas (P = .006), and 5.9 times more likely to have a family member who worked in agriculture (P < .001). The only factors affecting paraquat exposures in pregnant women at childbirth were reporting the agricultural activity of digging in farm soil and working in the agricultural fields in the third trimester of pregnancy. Conclusions: These results show that pregnant women who work in agriculture or live in families that work in agriculture have higher exposures to the herbicides glyphosate and paraquat. The potential for long-term health impacts of these prenatal exposures to children should be evaluated, and greater regulation of the sale and use of herbicides should be considered in Thailand. 相似文献

The objective of this study was to evaluate whether prenatal exposures to organophosphate (OP) pesticides from maternal agricultural use are associated with neonatal neurobehavioral effects. A pilot study conducted in three provinces in Thailand measured maternal urinary metabolites of OP pesticides in pregnant women at 7 months gestation and at birth. Within 3 days of birth, 82 newborns underwent neurobehavioral testing using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Comparison of the NBAS test results with maternal OP metabolite levels found the neonates NBAS Habituation cluster score increased with maternal dimethylphosphate (DMP) levels (p = 0.04) while the Range of State score increased with total diethylphosphate (DEP) levels (p = 0.01). The Number of Abnormal Reflexes in the neonate also increased as maternal urinary total DEP levels increased (p = 0.06). These preliminary findings suggest that pre-natal exposures to OP pesticides can impact newborn neurodevelopment and support the need for a longitudinal evaluation of childhood neurodevelopment in relation to pesticide exposures in Thailand. 相似文献

ABSTRACTOrganic farming has been promoted in Thailand by King Rama the ninth. In addition to being healthier for consumers, organic farming is healthier for agricultural workers. The cross-sectional study was conducted to investigate the frequency of chronic disease conditions, accidents, health symptoms, and ergonomic problems among 243 conventional (pesticide using) farmers and 235 organic farmers. Data were collected using questionnaires in face-to-face interviews. The results indicated symptoms that could be related to pesticide exposure (skin rashes, water blisters, headache, dizziness, and loss of appetite) were significantly higher among conventional farmers than organic farmers. The organic farmers reported significantly more health symptoms such as hives, chest pain, mild fever, flatulence, and frequent urination than the conventional farmers. The organic farmers reported significantly more pain, numbness, or weakness in the wrists/hands, fingers, upper back, hips, and ankles/feet than conventional farmers. 相似文献
