According to a new study, prenatal exposure to paracetamol is associated with Attention deficit hyperactivity disorder (ADHD) and autism symptoms in childhood.The study, published in the European Journal of Epidemiology, was led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation.The epidemiological study of more than 70,000 children in six European cohorts has linked symptoms of ADHD and autism spectrum conditions (ASC) to the mothers' use of paracetamol (acetaminophen) during pregnancy.The six cohorts included in the study were:1. Avon Longitudinal Study of Parents and Children (ALSPAC)2. Danish National Birth Cohort (DNBC)3. Gene and Environment: Prospective Study on Infancy in Italy (GASPII)4. Generation R Study5. INMA (including four subcohorts)6. Mother-Child Cohort in Crete (RHEA)In total, the researchers analysed 73,881 children for whom data were available on prenatal or postnatal exposure to paracetamol, at least one symptom of ASC or ADHD, and main covariates. Depending on the cohort, 14 per cent to 56 per cent of the mothers reported taking paracetamol while pregnant.The study found that children exposed to paracetamol before birth were 19 per cent more likely to develop ASC symptoms and 21 per cent more likely to develop ADHD symptoms than children who were not exposed."Our findings are consistent with previous research," explained ISGlobal researcher Silvia Alemany, lead author of the study. "We also found that prenatal exposure to paracetamol affects boys and girls in a similar way, as we observed practically no differences.""Our results address some of the weaknesses of previous meta-analyses," commented Jordi Sunyer, researcher at ISGlobal and last author of the study."Considering all the evidence on the use of paracetamol and neurological development, we agree with previous recommendations indicating that while paracetamol should not be suppressed in pregnant women or children, it should be used only when necessary," added Sunyer.At some point during pregnancy, an estimated 46 per cent to 56 per cent of pregnant women in developed countries use paracetamol, which is considered the safest analgesic/antipyretic for pregnant women and children. However, mounting evidence has linked prenatal paracetamol exposure to poorer cognitive performance, more behavioural problems, and ASC and ADHD symptoms.Those previous studies have been criticised for their heterogeneity. In the new study, therefore, "an effort was made to harmonise the assessment of ADHD and ASC symptoms and the definition of paracetamol exposure," explained Alemany."The sample is large," she added, "and it includes cohorts from multiple European countries: the United Kingdom, Denmark, the Netherlands, Italy, Greece and Spain. We also used the same criteria for all of the cohorts, thereby reducing the heterogeneity of criteria that has hampered previous studies."The study also analysed postnatal exposure to paracetamol and found no association between paracetamol use during childhood and ASC symptoms.Nevertheless, the research team concluded that further studies are needed, given the heterogeneity of postnatal paracetamol exposure among the various cohorts, which ranged from 6 per cent to 92.8 per cent.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
