Dietary intake, capillary blood glucose, and activity level of activity-restricted, hospitalized, pregnant women in the third trimester: a pilot study
Bibliographic record
Abstract
Activity restriction in hospital is commonly prescribed by care providers to decrease the incidence of maternal or fetal morbidity in high-risk pregnancies. The purpose of this pilot descriptive study was to collect preliminary data on dietary intake, capillary blood glucose concentrations, and activity level in high-risk, activity-restricted, pregnant women in the third trimester of pregnancy. Dietary food intake records, capillary blood glucose, and daily pedometer step totals were investigated in 20 activity-restricted women over 7 consecutive days in hospital. Subjects were asked to collect hospital meal tickets, as well as record any additional items not provided by the hospital in a dietary log each day. Capillary blood glucose was collected every morning (fasting) as well as 1 h after breakfast (post-prandial) using a glucometer. Subjects wore a pedometer 24 h/d, and recorded step totals 4 times daily in a pedometer log. In the analysis, average energy and macronutrient intakes met dietary reference intake (DRI) recommendations, as did average intakes of all micronutrients, including maternal supplementation. Without supplementation, vitamin E and iron intakes were lower (p<0.05) than the DRI recommendations. Average fasting (4.6+/-0.5 mmol/L) and post-prandial (7.1+/-1.0 mmol/L) blood glucose concentrations in subjects without gestational diabetes (GDM) did not exceed Canadian Diabetes Association cut-off values for screening of GDM. The mean daily step total of 1579+/-936 was lower than ambulatory third-trimester women (6495+/-2282 steps; p<0.001). Results from this pilot study suggest that with maternal supplementation, these activity-restricted, hospitalized, pregnant women were meeting dietary recommendations, and did not have elevated capillary blood glucose. However, given the severity of activity restriction, these women may be at risk for consequences of extreme inactivity.

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.
