Frequently Asked Questions
According to WHO guidelines, a healthy BMI range is 18.5-24.9 for most adult women. However, this can vary based on age, ethnicity, and body composition. Women over 65 may have slightly different optimal ranges due to the 'obesity paradox' where slightly higher BMI may be protective.
Age significantly impacts BMI interpretation. Research shows that women over 40 may have optimal health outcomes at slightly higher BMI ranges (up to 26), and women over 65 may benefit from BMI ranges of 22-27. This is due to changes in muscle mass, bone density, and metabolic factors with aging.
BMI calculations are not applicable during pregnancy and breastfeeding due to natural weight changes for fetal development and milk production. Pregnancy weight gain should follow specific guidelines based on pre-pregnancy BMI, typically 25-35 pounds for normal weight women. Always consult your healthcare provider for personalized guidance.
No, BMI cannot distinguish between muscle and fat mass. Athletic women or those with high muscle mass may have elevated BMI despite having low body fat. In these cases, body composition analysis (DEXA scan, bioelectrical impedance) provides more accurate health assessment than BMI alone.
PCOS can make weight management more challenging due to insulin resistance and hormonal imbalances. Women with PCOS may benefit from maintaining BMI in the lower end of the healthy range (18.5-23) to help manage symptoms. A low-glycemic index diet and regular exercise are particularly beneficial for PCOS management.
Yes, research shows ethnic differences in BMI health risk relationships. Asian populations may have higher health risks at lower BMI (overweight ≥23, obese ≥27.5). These differences are due to variations in body composition, fat distribution, and genetic factors affecting disease risk.
