Summary of an article analyzing whether the size of the breast affects how women participate in physical activity.
355 women aged 42.3 (±18.4) (range 18-75) years (Australia).
- The Active Australia Survey.
- Breast scans: breast volume.
- Participants were divided into 4 breast sizes:
- small (breast volume <350 ml, n = 98)
- medium (breast volume 350-700 ml, n = 132)
- large (breast volume 701-1200 ml, n = 82) and
- hypertrophic (breast volume >1200 ml, n = 43)
- BMI in breast size groups was:
- small: 87% within “normal” BMI
- medium: 49% within “normal” BMI
- large: 54% within “obese” BMI
- hypertrophic: 77% within “obese” BMI
- Physical activity participation by breast size:
- small breast group spent more time in physical activity than hypertrophic breast group
- small breast group spent more time in vigorous physical activity than the large or hypertrophic group
- no difference in time spent in moderate physical activity
- Percentage of women reporting that breast size negatively affects their physical activity participation increased with breast size. The most affected activities were: running/jogging, aerobics/dance/jumping/gym, and team sports/basketball/netball.
