RESUMEN

BACKGROUND: Organophosphorus (OP) pesticides are widely used worldwide. The effect of OP exposure during pregnancy on the offspring is inconsistent in the current literature. Moreover, similar studies in the Middle East are lacking. PURPOSE: To examine the effects of OP exposure in utero on the outcome of pregnancies in an agricultural region in Jordan. METHOD: A prospective study, employing a questionnaire to collect women demographic data. Hospital records were collected for newborns' birth data. In addition, urine samples during the third trimester were collected from pregnant women and then analyzed for six OP metabolites to measure exposure. RESULTS: One of the metabolites, DEDTP, was negatively correlated with gestational age and Apgar scores 1 and 5. There were no other significant associations. CONCLUSIONS: Exposure to OP during pregnancy is not highly associated with any negative anthropometric characteristics of the newborns; it is probably offset by other factors.

RESUMEN

Consanguineous or cousin marriages are very common in Saudi Arabia. However, owing to limited studies and insufficient knowledge about genetic diseases/disorders, many couples are unaware of the increased health risks for their offspring. Among the inherited and complex diseases from parents' consanguinity, obesity is common; therefore, we examined the prevalence of obesity in the offspring of first-cousin consanguineous couples in Saudi Arabia. In this questionnaire-based study, 657 individuals (mean age = 18.7 ±â€¯10.2 years; age range = 2-65 years) who were residing in Riyadh, Saudi Arabia participated. Among them, almost 90% were native Saudis. Participants mean body mass index (BMI) was 24.5 ±â€¯9.1 kg/m2. Sex- stratified demographic details confirmed a significant association between age and BMI (p < .001). We confirmed that adolescents and adults were more prone to develop obesity. Adults and non-Saudi participants were three times more likely to develop obesity if they had first-cousin consanguineous parents than those who did not. Of the 30% of participants who were obese, 100 will be selected for Phase II, in which we plan to perform exome sequencing.
