Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. this study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: the results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. this organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. the health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: to reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.

Background: Evidence regarding the effectiveness of prenatal nutritional supplements has mainly considered anthropometric pregnancy outcomes. the effect on markers of health and disease， such as offspring telomere length (tL) and mitochondrial DNA content (mtDNAc) is unknown. Objectives: We assessed the efficacy of maternal multiple micronutrient (MMN)-fortified balanced-energy protein (BEP) and iron-folic acid (IFA) supplementation on newborn tL as a secondary outcome and mtDNAc as a non-declared outcome. Design: We conducted a randomized controlled trial in rural Burkina Faso， among pregnant females (15-40 years old) enrolled at s of gestation. Mothers received either MMN-fortified BEP and IFA (intervention) or IFA only (control) throughout pregnancy. Whole arterial blood samples were collected from the umbilical cord of 104 control and 90 intervention group infants， respectively. Average relative tL and mtDNAc were measured using quantitative polymerase chain reaction. Linear regression models were fitted to assess tL and mtDNAc differences across trial arms. Results: We found that a combined daily MMN-fortified BEP supplement and IFA tablet did not affect newborn tL [β = -0.010 (95% CI: -0.057， 0.036); P = 0.662] or mtDNAc [β = 0.065 (95% CI: -0.203， 0.073); P = 0.354]， as compared to an IFA tablet alone. these findings were confirmed (P > 0.05) by adjusting the regression models for potential prognostic factors of study outcomes at enrollment. Exploratory analyses indicated higher， but non-significantly different mtDNAc among children born either small-for-gestational age， low birthweight， or preterm. Conclusions: Newborns from mothers who received daily nutritional supplements across gestation did not have different relative tL or mtDNAc.
