Abstract

Background: Prenatal exposure to cannabis (or more specifically, delta 9-tetrahydrocannabinol [Δ9-THC]) has been consistently linked to low birthweight. Animal models further show that Δ9-THC is associated with rapid postnatal growth. Whether this association is modified by breastfeeding is unknown.

Methods: In this exploratory study, we followed 128 mother-child pairs through 3 years. Urinary Δ9-THC and cannabidiol (CBD) were measured mid-gestation. Generalized linear models estimated the associations between Δ9-THC and neonatal body composition. A mixed-effects model estimated the association between Δ9-THC and body mass index (BMI) z-score trajectories. Interaction was assessed by a three-way product term (Δ9-THC × breastmilk months × age).

Results: Fifteen children (12%) had Δ9-THC exposure; three had concomitant CBD exposure. Prenatal exposure to Δ9-THC alone was associated with lower fat mass (-95 g, 95% confidence interval [CI]: -174, -14) and neonatal adiposity (-2.1%; 95% CI: -4.2, -0.4) followed by rapid postnatal growth (0.42 increase in BMI z-score per square root year; 95% CI: 0.12, 0.72). Breastfeeding modified this association (p = 0.04), such that growth was similar for those breastfed for 5 months whereas a shorter duration of breastfeeding was associated with 1.1 higher BMI z-score at 3 years (95% CI: 0.21, 2.05).

Conclusions: Our study suggests that prenatal exposure to Δ9-THC may alter early-life growth. Breastfeeding may stabilize rapid postnatal growth, but the impact of lactational exposure requires further investigation.

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
