Is 47 kg underweight for 160 cm? Generally, a weight of 47 kg for someone who is 160 cm tall is considered underweight. This assessment is based on the Body Mass Index (BMI), which is a common method used to determine if an individual is underweight, normal weight, overweight, or obese.

Understanding BMI and Its Implications

What is BMI and How is it Calculated?

Body Mass Index (BMI) is a numerical value derived from a person’s weight and height. It is used to categorize individuals into different weight classes. The formula for calculating BMI is:

[ \text{BMI} = \frac{\text{weight in kilograms}}{(\text{height in meters})^2} ]

For someone who is 160 cm tall and weighs 47 kg, the BMI calculation would be:

[ \text{BMI} = \frac{47}{(1.6)^2} \approx 18.36 ]

BMI Categories and Health Implications

According to the World Health Organization (WHO), the BMI categories are as follows:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5–24.9
• Overweight: BMI 25–29.9
• Obesity: BMI 30 or greater

With a BMI of approximately 18.36, a person weighing 47 kg at 160 cm falls into the underweight category. Being underweight can have several health implications, including:

• Nutritional deficiencies: Lack of essential vitamins and minerals.
• Decreased immune function: Increased susceptibility to infections.
• Bone health issues: Higher risk of osteoporosis and fractures.
• Fertility problems: Potential challenges with reproductive health.
