Abstract
- This study aims to compare pregnancy outcomes in four contaminated areas to those observed in a non-contaminated area of similar socioeconomic status. A cross-sectional study was carried out. A structured and pre-tested questionnaire was administered to population-based samples of 788-920 families in each of the five studied areas. The exposure assessment used was an ecological measure. Using logistic regression, odds of several pregnancies outcomes (pregnancy occurrence, miscarriage, stillbirth, prematurity, low birth weight, congenital malformation, and multiple births) were estimated after adjustment for potential confounders such as socioeconomic, demographic, and substance abuse factors. We adopted a statistical significance level of 5 %. In three of the four exposed areas, pregnancy occurrence was reduced in comparison to the control area (Area 2, odds ratio (OR) = 0.68, 95 % CI = 0.54-0.86; Area 3, OR = 0.76, 95 % CI = 0.60-0.97; Area 4, OR = 0.71, 95 % CI = 0.56-0.90). Also, a significantly increased odds of miscarriage for living in Area 3 (OR = 1.83, 95 % CI = 1.07-3.12) was found. The other pregnancy outcomes were not significantly elevated in the exposed areas. In conclusion, this study shows evidence of reduced pregnancy occurrence and increased miscarriage occurrence in some of the contaminated areas, compared to the control area. [ABSTRACT FROM AUTHOR]
