Statistical Analysis:
This pilot study included analyses on women who were diagnosed with GDM
and began the intervention between 28-30 wk gestation. Statistical
analyses were completed using a fixed effects Linear Mixed Model to
compare changes in glucose and physical activity from Baseline (28-30
weeks) through to ~35 weeks between groups (Group, Time,
Interaction). T-tests and Chi square analysis were used to compare
differences between baseline demographics and birth outcomes. Data
matched for pre-pregnancy BMI is also presented. Pearson correlation
analysis was performed between postprandial and physical activity
outcomes against birth weights to assess whether there was a
relationship between physical activity or glucose and neonatal birth
weight. Data are expressed as means or frequency.
