In a significant finding that challenges the well-trodden narrative surrounding foetal alcohol spectrum disorder (FASD), a new study suggests that the role of fathers in the drinking habits of expectant parents must not be underestimated.
While the damaging effects of maternal alcohol consumption during pregnancy have long been established, international researchers, including contributors from Stellenbosch University (SU), have uncovered evidence that suggests a father’s drinking can also negatively impact a child’s growth and development.
The study, published in the journal Alcohol: Clinical & Experimental Research, elaborates on the complex dynamics of alcohol use in parenting, specifically highlighting how a father’s alcohol consumption may contribute to developmental challenges in children by the age of seven.
Analysis of data from five studies conducted among Grade 1 learners in the Western Cape aimed to ascertain whether paternal drinking patterns influenced the children diagnosed with FASD.
Caregivers were asked to answer questionnaires concerning risk factors associated with the condition, offering rich insights into the fathers’ roles.

Researchers stress that there is a growing awareness of the various factors beyond a mother’s alcohol consumption that can shape a child’s future. The results indicate that children whose fathers drank frequently were more likely to present with reduced height, smaller head sizes, and lower verbal IQ scores.
Alarmingly, the most pronounced risks to a child’s development arose when both parents consumed alcohol during pregnancy, revealing an intricate interplay between paternal and maternal behaviours.
According to the study’s data, between 66% and 77% of fathers of children within the FAS spectrum drank during their partner’s pregnancy, averaging 12 drinks per drinking day. T
he researchers established a definitive correlation: the more a father drank, the smaller the head circumference of their child an important marker for brain development. Specifically, fathers who averaged five or more drinks in a single session were linked to shorter children with notably small head sizes and poorer performance on verbal intelligence assessments.
However, while the father’s drinking had observable effects on child growth and cognitive abilities, the study clarifies that it did not correlate strongly with the likelihood of a child being diagnosed with FASD when considered alone.
The gravest implications emerged when combining the drinking patterns of both parents, where serious symptoms of FASD were observed a poignant reminder of the cumulative effects of alcohol on fetal development.
In discussions around the mechanisms behind these findings, researchers noted that while the precise reasons behind the paternal effects are still being investigated ranging from potential impaired sperm quality to other epigenetic influences the evidence concerning fathers’ contributions to FASD underscores an important cultural and health message: alcohol consumption during pregnancy does not solely rest on the shoulders of mothers.
This study urges a paradigm shift, inviting further exploration into the societal and familial dynamics that inform alcohol consumption amongst expectant parents.
As awareness grows, the hope is that collective responsibility can lead to better health outcomes for children at risk of FASD, paving the way towards a more informed community that understands the implications of both parents’ behaviours during crucial developmental periods.
