Moms who are obese before conception may put their children at a higher risk of developing obesity, reports a new study.
A systematic review and meta-analysis identified significantly increased odds of child obesity when mothers have obesity before conception, according to a study published in the open-access journal PLOS Medicine by Nicola Heslehurst of Newcastle University in the UK, and colleagues.
Obesity is a leading cause of life-long poor health globally, and is significantly associated with inequalities. Capitalizing on opportunities for early-life prevention of obesity is a priority for public health, global health and clinical practice. Understanding the association between childhood obesity and maternal pre-pregnancy weight status would inform policy and practice by allowing resources to be channeled into intervention.
The results revealed significantly increased odds of child obesity with maternal obesity (OR 3.64, 95% CI 2.68-4.95) and maternal overweight (ORs 1.89, 95% CI 1.62-2.19). Significantly increased odds were observed for child overweight/obesity (OR 2.69, 95% CI 2.10-3.46) and for child overweight (OR 1.80, 95% CI 1.25-2.59) with maternal obesity. This study provides substantial evidence for the need to develop interventions that commence prior to conception, to support women of childbearing age with weight management, in order to combat intergenerational obesity.
According to the authors, paying more attention to the preconception period in obesity prevention interventions may help to address the complex early-life inequalities associated with obesity development.
