It is best for seniors to talk to a healthcare provider or registered dietitian, who can give them advice based on their needs and health status. However, the interpretation of the results may be different.Īccording to the World Health Organization, a BMI value of 18.5-24.9 is considered a healthy weight range for adults aged 18–65 years, but for seniors, a slightly higher BMI may be more appropriate. To calculate BMI for seniors, the same formula is used as for other adults: weight in kilograms divided by height in meters squared. It’s because older adults may have changes in their body composition, like a decrease in muscle mass and an increase in body fat, which can affect BMI values.

It is best for athletes to talk to a healthcare professional or sports nutritionist who can look at their body and make recommendations.

In such cases, other methods such as skinfold measurements or bioelectrical impedance analysis may be more appropriate. But because athletes or bodybuilders tend to have higher levels of muscle mass, which weighs more than fat, BMI may not be an accurate measurement of body fat for them. CategoryĬalculating BMI for athletes is the same as for non-athletes. The Centers for Disease Control and Prevention (CDC) recommends BMI categorization for children and teens between age 2 and 20. Weight categories for children are established based on these percentiles, including: For example, a 25th percentile BMI for a 6-year-old female child would indicate that the child's weight is higher than 25% of girls aged 6. The resulting BMI value is then compared to other children of the same age and gender using percentages and percentiles. To determine this, doctors start by calculating the child’s BMI using their height and weight. Instead, doctors use a specific chart to monitor whether a child’s weight is appropriate for their height.

It’s because males tend to have more muscle mass than females, which can affect their body mass index. However, the BMI scale used to interpret the results may differ slightly for males and females. The Centers for Disease Control and Prevention (CDC) BMI-for-age percentiles growth charts.

The Formula for Calculating BMI is BMI Metric Units formula (kg, cm, m):įor example, if you weigh 70 kilograms and are 1.75 meters tall, your BMI would be calculated as follows:

The BMI formula divides a person’s weight in kilograms by the square of their height in meters. If you don’t have access to a metric tape measure or ruler, you can convert your height from feet and inches to meters by multiplying your height in feet by 0.3048 and adding your height in inches multiplied by 0.0254. Use a tape measure or ruler to measure your height in meters. If you don’t have access to a scale that measures in kilograms, you can convert your weight from pounds to kilograms by dividing your weight in pounds by 2.205. You can use a scale to measure your weight in kilograms. To calculate your BMI manually, you have to find out your weight and height.
