Explanation: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems objectively with their patients.
Details: BMI is a screening tool that can indicate whether a woman is underweight, healthy weight, overweight, or obese. According to Heart Foundation guidelines, maintaining a healthy BMI is important for cardiovascular health.

Q1: What is a healthy BMI range for women?
A: For adult women, 18.5-24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
Q2: Does BMI differ for women and men?
A: The same BMI ranges apply to both genders, though women naturally have higher body fat percentages than men at the same BMI.
Q3: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, so muscular women may have high BMI without excess fat. It also doesn't account for fat distribution.
Q4: Is BMI accurate for all women?
A: BMI may be less accurate for very tall or short women, pregnant women, and certain ethnic groups with different body compositions.
Q5: What other measurements complement BMI?
A: Waist circumference and waist-to-hip ratio provide additional information about fat distribution and health risks.
