Pregnancy Family-based Nutrition and Exercise Lifestyle Intervention Program Re-introduced Postpartum Reduces Offspring Fatness at 1-year.
Bibliographic record
Abstract
Babies born to overweight (OW; pre-pregnancy body mass index (BMI) 25.0 to 29.9 kg/m2) and obese (OB; pre-pregnancy BMI ≥30.0 kg/m2) women are at risk for obesity and co-morbidities. PURPOSE:To determine maternal weight retention and baby fatness at 2, 6 and 12 months post-delivery following a pre- and post-natal lifestyle intervention. METHODS:OW and OB pregnant women were introduced to a Nutrition and Exercise Lifestyle Intervention Program (NELIP) at 16-20 weeks gestation, consisting of a controlled meal plan (daily 2000 kcal and 200g carbohydrate goals) combined with walking (25 mins, 3-4 times/week, adding 2 min/session/week until reaching 40 min) until delivery. Women (N=76) returned to the lab at 2, 6 and 12 months post-delivery for follow-up but with no post-partum intervention. A second group of OW/OB women followed the original NELIP plus a Family-based Behavioural Treatment (FBBT) plan (group sessions) (NELIP+FBBT; N=52). The intervention was re-initiated at 2 months post-delivery, included a group stroller walking program (25 min/session, 3 times/week adding 5 min until reaching 45 min), and a similar nutrition program, including group sessions with family members (FBBT) and education regarding infant feeding practices. Women were followed until 1 year post-delivery. RESULTS:The two-pronged approach (NELIP+FBBT) appeared to be successful in reducing fatness in babies of OW and OB women, compared to our original NELIP with no postpartum intervention. Although the average BMI for the infants at 2, 6 and 12 months were not different, we found a significant reduction in body fatness at 6 months (NELIP+FBBT=2020±375 gm vs NELIP pregnancy only=2414±648 gm; p=0.03), which continued to 1 year of age (2359±644 gm vs 2788±439 gm; p=0.05, respectively). This was reflected in a reduction in percent body fat in 1 year old infants (23.3±2.9% vs 25.6±2.5%; p=0.05, respectively). By one year post-delivery, maternal weight retention was 1.2±7.5 kg in the combined NELIP+FBBT group and 1.8±5.5 kg in the NELIP only group; p>0.05. CONCLUSIONS:Preliminary results suggested that in OW and OB women a lifestyle intervention initiated during pregnancy should be re-introduced at 2 month postpartum to reduce baby fatness in the first year of life.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
