Associations of Physical Activity and Lactation Duration With Cardiometabolic Risk Factors: The CARDIA Study
Main finding · Cardiometabolic risk scoreResult — go to the resultβ −0.15 95% CI −0.25 to −0.04Authors' conclusion
Above average PA throughout adulthood combined with ≥3 months of lactation was associated with lower risk scores. Participants with either behavior had lower risk vs those with neither behavior.
