Description
Overweight (OW; body mass index [BMI] of 25.0 to 29.9 kg/m² ), and obesity (OB; BMI of 30 and greater kg/m²) are conditions where excessive fat accumulation presents a risk to health. Prepregnancy BMI and maternal excessive gestational weight (EGWG) gain are risk factors for higher infant birthweight and childhood OW or OB. The Nutrition and Exercise Lifestyle Intervention Program (NELIP) is a combined intervention designed to prevent EGWG in individuals with OW and OB. This study was a convenience sample from a larger trial using the NELIP with family based behavioural treatment (FBBT) to increase program adherence. The objective of this study was to investigate if an antenatal NELIP with FBBT reinforced at 2 months postpartum (Group A) decreases the prevalence of large infants (BMI ≥85th percentile) up to 1 year of age compared to a postpartum only NELIP with FBBT (Group B). The main findings of this study were that Group A had lower mean gestational weight gain and EGWG, but no difference in the prevalence of large infants compared to Group B. Furthermore, Group A had higher prepgregnancy BMI, and higher infant anthropometric measurements up to 1 year of age compared to Group B. In conclusion, prepregnancy BMI may be more important than GWG as a determinate of infant anthropometrics up to 1 year of age. Future research is necessary to confirm this finding.

Effect of a Nutrition and Exercise Lifestyle Intervention Program (NELIP) with a Family based Behavioural Treatment (FBBT) during Pregnancy and Postpartum on the Prevalence of Large Infants up to 1 Year of Age
