To determine if a person is undernourished, we need to consider their BMI (Body Mass Index). BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. The World Health Organization (WHO) has established BMI categories to assess nutritional status, and a BMI of less than 18.5 is considered undernourished.
Explanation:
To solve this problem, we need to understand the BMI categories set by the WHO.
1. BMI less than 18.5: This category is classified as underweight or undernourished. Individuals with a BMI below 18.5 may not be consuming enough nutrients to maintain a healthy weight.
2. BMI between 18.5 and 24.9: This category is classified as a normal weight. Individuals with a BMI within this range are considered to have a healthy weight for their height.
3. BMI between 25.0 and 29.9: This category is classified as overweight. Individuals with a BMI within this range may have excess body weight, which can increase the risk of various health conditions.
4. BMI equal to or greater than 30.0: This category is classified as obese. Individuals with a BMI within this range have a significantly higher risk of developing obesity-related health conditions.
Therefore, based on the WHO BMI categories, an individual is considered undernourished if their BMI is less than 18.5.
Conclusion:
In conclusion, a person is considered undernourished if their BMI is less than 18.5. It is important to maintain a healthy BMI to ensure proper nutrition and overall well-being.
