Abstract Currently, there is contradictory evidence for the risk of adverse pregnancy outcomes associated with maternal exposure to disinfection byproducts (DBPs). We examine the association between maternal exposure to trihalomethanes (THMs) in drinking water and adverse pregnancy outcomes, including premature birth, low birth weight (LBW) and small for gestational age (SGA). In total, 1,167 women older than 18 years were enrolled at public antenatal venues in two geographical districts. For each district, we measured the levels of residential drinking water DBPs (measured in THMs) through regulatory data and routine water sampling. We estimated the individual uptake of water of each woman by combining individual water use and uptake factors. Increased daily internal dose of total THMs during the third trimester of pregnancy significantly increased the risk of delivering premature infants (AOR 3.13, 95% CI 1.36–7.17). The risk of premature birth was also positiviely associated with exposure to total THMs during the whole pregnancy (AOR 2.89, 95% CI 1.25–6.68). The risk of delivering an SGA and LBW infant was not associated with maternal exposure to THMs. Our findings suggest that exposure to THMs is associated with certain negative pregnancy outcomes. The levels of THMs in water should be routinely monitored.

Adverse Pregnancy

Adverse pregnancy outcomes can bring enormous losses to both families and the society. Thus, pregnancy outcome prediction stays a crucial research topic as it may help reducing birth defect and improving the quality of population. However, recent advances in adverse pregnancy outcome detection are driven by data collected after mothers having been pregnant. In this situation, if a bad pregnancy outcome is diagnosed, the parents will suffer both physically and emotionally. In this paper, we develop a deep learning algorithm which is able to detect and classify adverse pregnancy outcomes before parents getting pregnant. We train a multi-layer neural network by using a dataset of 75542 couples’ multidimension pre-pregnancy health data. Our model outperforms some of algorithms in accuracy, recall and F1 score.

Chlorination by-products (CBPs) in drinking water have been associated with an increased risk of adverse pregnancy outcomes, including small for gestational age at term (term-SGA) and preterm delivery. Epidemiological evidence is weakened by a generally inaccurate exposure assessment, often at an ecological level. A case control study with incident cases was performed in nine Italian towns between October 1999 and September 2000. A total of 1,194 subjects were enrolled: 343 preterm births (26th–37th not completed week of pregnancy), 239 term-SGA (from 37th completed week, and weight less than the lowest 10th percentile) and 612 controls. Exposure was assessed both by applying a questionnaire on mothers' personal habits during pregnancy and by water sampling directly at mothers' homes. Levels of trihalomethanes (THMs) were low (median: 1.10 µg l−1), while chlorite and chlorate concentrations were relatively high (median: 216.5 µg l−1 for chlorites and 76.5 µg l−1 for chlorates). Preterm birth showed no association with CBPs, while term-SGA, when chlorite levels ≥200 µg l−1 combined with low and high levels of inhalation exposure are considered, suggested a dose-response relationship (adjusted-Odds Ratios (ORs): 1.52, 95%CI: 0.91–2.54 and 1.70, 95%CI: 0.97–3.0, respectively). A weak association with high exposure levels of either THMs (≥30 µg l−1), or chlorite or chlorate (≥200 µg l−1) was also found (adjusted-OR: 1.38, 95%CI: 0.92–2.07). Chlorine dioxide treatment is widespread in Italy; therefore, chlorite levels should be regularly and carefully monitored and their potential effects on pregnancy further evaluated and better understood.

CONTEXT AND OBJECTIVE: Previous adverse pregnancy outcomes (recurrent spontaneous abortion, fetal death, preterm birth or early neonatal death) can affect the quality of life of pregnant women. The objective of this study was to compare the quality of life and the prevalence of symptoms of anxiety and depression among pregnant women with and without these antecedents. DESIGN AND SETTING: An analytical cross-sectional study was performed in four settings (two high-risk and two low-risk prenatal clinics) in the city of Campinas, São Paulo, Brazil. METHODS: A total of 240 women were interviewed by a single investigator between the 18th and 24th weeks of gestation: 120 women with prior adverse pregnancy outcomes (group 1) and 120 women with no such history (group 2), matched according to their numbers of living children. Sociodemographic variables were collected and two questionnaires were used: the Short Form-36 quality-of-life questionnaire and the Depression and Anxiety Scale. RESULTS: The women in group 1 had lower scores in all the items on the quality-of-life questionnaire. Depression and anxiety were more frequent in group 1 (P < 0.0001). An inverse correlation was found between the Short Form-36 domains and anxiety and depression. CONCLUSIONS: Women with histories of recurrent spontaneous abortion, fetal death, preterm birth or early neonatal death seem to have poorer quality of life and more symptoms of anxiety and depression during their subsequent pregnancy, compared with those without such antecedents.

Abstract Epidemiological studies have found that maternal exposure to disinfection by-products (DBPs) may lead to adverse pregnancy outcomes although the findings tend to be inconsistent. The objective of this study was to systematically review the evidence in associated with drinking water DBP exposure in relation to adverse pregnancy outcomes. Peer-reviewed articles were identified using electronic databases searched for studies published in the English language. Studies selected for review were evaluated for exposure assessment, confounders, and analyses risks of bias in the selection, outcomes assessment, and attrition. A comprehensive search and screening yielded a total of 32 studies, of which 12 (38%) reported a statistical association between maternal exposure to DBPs and adverse pregnancy outcomes. A maternal exposure to trihalomethanes (THMs) shows an increased risk of small for gestational age (SGA) and slightly increased risk of pregnancy loss. Risks of bias were low among the studies included in the review. Evidence on association relating to adverse pregnancy outcomes to DBP exposure is still less significant. There is a need for future robust research in this field, with the use of urinary trichloroacetic acid (TCAA) biomarkers as a direct exposure assessment method for this field.
