Study focus
This study examined the impact of maternal well-being on behavior change during pregnancy, finding significant improvements in physical activity and dietary intake.
Understanding the role of maternal well-being in behavior change is crucial for developing effective interventions during pregnancy. Enhancing well-being could lead to healthier lifestyles for mothers, potentially benefiting both maternal and fetal health.
The effectiveness of the intervention remains unclear due to limited data. The study's findings may not be generalizable beyond the enrolled population. Potential confounding factors were not fully controlled.

Maternal well-being significantly influenced the positive stage of behavior change (OR 1.03, p < 0.01).
The predicted probability of reaching the highest stage of behavior change increased from 43% to 92% with improved well-being.
The intervention group increased moderate intensity exercise by an average of 18 minutes per week.
