What Threatens Baby's Health More Than Alcohol or Cigarettes During Pregnancy?..."Parents' Wallet"

University of Exeter Research Team Analyzes 230,000 Parents and Children
Socioeconomic Status Accounts for 15% of Impact, Smoking Just 6%
"Poverty and Inequality Worsen Child Health"

An international joint study has found that a family's socioeconomic environment has a greater impact on a child's health than parental smoking or drinking during pregnancy.

According to Yonhap News Agency, a research team led by Dr. Gemma Sharp at the University of Exeter in the UK published a paper on July 23 (local time) analyzing more than 230,000 parents and children in the UK and Norway in the international academic journal PLOS Medicine. The researchers stated, "Family socioeconomic position (SEP) showed a stronger and more consistent association with child health than parental smoking, alcohol consumption, or caffeine intake before and during pregnancy."

The analysis used data from four large-scale cohort studies tracking children born in the UK and Norway between 1991 and 2008 and their parents. Combining these datasets, the research team examined up to 232,139 individuals, comparing parental smoking, alcohol, and caffeine intake during pregnancy, as well as socioeconomic position reflected by education and occupation, to 72 health indicators measured from birth through age 11. The health indicators included birth size, body mass index (BMI), mental health, behavioral issues, social communication skills, blood pressure, allergies, and more.

Statistically significant correlations with child health were confirmed for only 6% of indicators for parental smoking, 3% for alcohol consumption, and 0.4% for caffeine intake. In contrast, low family socioeconomic position accounted for 15%, exceeding all three health behaviors.

The research team suggested that these findings indicate a need to realign the focus of existing research. While studies based on the "Developmental Origins of Health and Disease" (DOHaD) hypothesis have traditionally focused on maternal health behaviors before and during pregnancy, the researchers noted that these behaviors themselves are likely intertwined with socioeconomic environment, paternal behavior, and postnatal environment.

Dr. Sharp, who led the study, said, "Socioeconomic vulnerability was more consistently associated with child health outcomes than either parent's smoking, alcohol, or caffeine intake," and added, "The socioeconomic environment in which a child grows up may have a greater impact on health than specific parental behaviors during pregnancy."

However, some experts warned that the findings should not be interpreted to downplay the importance of pregnancy health management. Asma Khalil, Professor of Maternal Fetal Medicine at St George's Hospital, University of London, commented via the UK Science Media Centre (SMC) on the same day that "This result should not be taken to mean that maternal health behaviors during pregnancy are unimportant," emphasizing, "This study also confirmed the association between maternal smoking and low birth weight, as well as increased childhood BMI and behavioral problems."

Suggestions also followed calling for policy responses to the findings. Andrew Pollard, Director of the Oxford Vaccine Group at the University of Oxford, cited reports on child health released over the past three years by the Academy of Medical Sciences, the Institute for Fiscal Studies, and the Royal College of Paediatrics and Child Health, pointing out, "Societal poverty and inequality are causing worsening health outcomes for children," and stressed, "We must refocus on mitigating inequality."
