Insights
Accelerated early growth in children from high-risk pregnancies is linked to increased childhood adiposity. Promoting breastfeeding and reducing cesarean births may support healthier postnatal growth.
Area of Science:
- Pediatrics
- Public Health
- Maternal-Fetal Medicine
Background:
- Early childhood growth patterns are linked to later adiposity.
- The influence of lifestyle factors on this association, particularly in high-risk pregnancies, requires further investigation.
Purpose of the Study:
- To examine the relationship between growth profiles in children born to mothers with high-risk pregnancies and their adiposity at age 5.
- To assess the impact of lifestyle and antenatal/postnatal exposures on this association.
Main Methods:
- Prospective cohort study of 609 children from the Finnish Gestational Diabetes Prevention Study (RADIEL).
- Latent class mixed models were used to identify growth profiles based on ponderal index.
- Adiposity was measured using anthropometrics and body composition analysis at age 5.
Main Results:
- Three growth profiles were identified: ascending, intermediate, and descending.
- Children with ascending growth profiles exhibited higher body fat percentage, ISO-BMI, and waist circumference at age 5.
- Ascending and intermediate growth profiles were associated with higher adiposity, even after adjusting for lifestyle factors and prepregnancy BMI. Meeting lifestyle intervention goals and exclusive breastfeeding for 3+ months were associated with lower odds of ascending growth.
Conclusions:
- Accelerated early growth in children from high-risk pregnancies is associated with increased adiposity at age 5.
- Lifestyle factors did not fully explain this association.
- Recommendations include promoting breastfeeding and reducing cesarean deliveries to potentially improve postnatal growth outcomes.
Context:
Early growth is associated with childhood adiposity, but the influence of lifestyle remains unknown.
Objective:
This work aimed to investigate the association of growth profiles from high-risk pregnancies with adiposity at age 5 years, taking into account lifestyle and several antenatal/postnatal exposures.
Methods:
This prospective cohort study.
Included:
609 children born during the Finnish Gestational Diabetes Prevention Study (RADIEL), recruiting women with body mass index (BMI) greater than or equal to 30 and/or prior gestational diabetes mellitus (GDM) (2008-2013). Altogether 332 children attended the 5-year follow-up (2014-2017). Main outcome measures included growth profiles based on ponderal index (PI = weight/height3), investigated using latent class mixed models. Adiposity was assessed with anthropometrics and body composition (InBody720).
Results:
We identified 3 growth profiles: ascending (n = 82), intermediate (n = 351), and descending (n = 149). Children with ascending growth had a higher body fat percentage, ISO-BMI, and waist circumference (P < .05) at age 5 years. Ascending (β 4.09; CI, 1.60-6.58) and intermediate (β 2.27; CI, 0.50-4.03) profiles were associated with higher fat percentage, even after adjustment for age, sex, gestational age, diet, physical activity, education, and prepregnancy BMI. Similar associations existed with ISO-BMI. After adjusting for age and education, ascending growth was associated with prepregnancy BMI (odds ratio [OR] 1.06; CI, 1.01-1.12), primiparity (OR 3.07; CI, 1.68-5.62), cesarean delivery (OR 2.23; CI, 1.18-4.21), and lifestyle intervention (OR 2.56; CI, 1.44-4.57). However, meeting the intervention goals and exclusive breastfeeding for 3 months or more were associated with lower odds of ascending growth.
Conclusion:
Accelerated early growth was associated with higher adiposity in 5-year-old children from high-risk pregnancies, even when adjusted for lifestyle. Reducing cesarean deliveries and promoting breastfeeding may be beneficial for postnatal growth.
