BACKGROUND: Perinatal alcohol and non-prescribed substance use may be detrimental to foetal and infant growth.
AIM: This observational study investigated how combined and continued alcohol and non-prescribed substance use throughout antenatal and 1-year postnatal periods were associated with adverse child length and weight outcomes up to 24 months.
SETTING: Data from participants (n = 1098) with information on alcohol and non-prescribed substance use and infant and child outcomes, were drawn from a prospective birth cohort in the Drakenstein Child Health Study (DCHS), conducted in the Western Cape province of South Africa.
METHODS: Generalised estimating equations were conducted on standardised child length and weight outcomes at 12, 18 and 24 months.
RESULTS: Non-prescribed substances consisted mostly of tobacco use (77%). Child length and weight were significantly lower in those exposed to the combined use of alcohol and substances compared to no-use and all other use groups (p < 0.001), as confirmed by multivariable analyses. Child length and weight were also significantly lower in those exposed to alcohol and/or substance use throughout the antenatal and 1-year postnatal periods, as confirmed by multivariable analyses.
CONCLUSION: Interventions to address the potential long-term adverse effects of combined alcohol and substance use particularly tobacco use, as well as continuous use throughout antenatal and early postnatal periods on subsequent child growth, are needed.
CONTRIBUTION: This study has contributed to the field by showing that combined and continued use of alcohol and other substances during pregnancy and postpartum is associated with impaired early child growth.
