A recent study to better understand modifiable factors that may affect a woman’s ability to conceive a child suggest that walking may help women with a history of pregnancy loss improve their chances of becoming pregnant.
The study of healthy women ages 18 to 40 years old with a history of one or two pregnancy losses was conducted by researchers in the School of Public Health and Health Sciences at the University of Massachusetts Amherst. It was published in Human Reproduction.
For the 1,214 women in the study, the association of walking with the ability to become pregnant, known as fecundability, varied significantly by body mass index, the authors report. Among overweight/obese women, walking at least 10 minutes at a time was associated with improvement in fecundability. Further, in statistically adjusted models, women reporting more than four hours a week of vigorous activity had significantly higher pregnancy chances compared to no vigorous activity.
Moderate activity, sitting and other activity categories were not associated with fecundability overall or in BMI-stratified analyses, they add.
The researchers conclude that “these findings provide positive evidence for the benefits of physical activity in women attempting pregnancy, especially for walking among those with higher BMI.”
