here comes the bad news: there's no biological reason why a certain BMI is healthy, and others aren't, its all statistical. We have mentioned a healthy BMI for men, but we have yet to define what it is exactly, so let's do that now. BMI prime is also available for other populations, but since this is a BMI calculator for males, we shall focus only on the male side of BMI prime. BMI prime is a derived measure that compares your BMI value as a man with the normal BMI for men or the healthy BMI for men. The result in the calculator shows the highest percentile in the group.Īnother measure you should be familiar with is the so-called BMI prime. Any precision lost in the process of reducing from having 100 percentiles to having 10 groups of 5-percentiles size is irrelevant in the grand scheme of things.įor example, in this BMI calculator for men, we have grouped the percentiles in 9 groups distributed as follows: 0th-5th, 5th-10th, 10th-15th, 15th-25th, 25th-50th, 50th-75th, 75th-85th, 85th-90th, 90th-95th.

The reality is that this is not a big issue, especially if we consider that the percentile is a statistical comparison tool that we apply on a purely statistical descriptor such as BMI. What this means is that it is very rare to hear about "48th percentile", and you're much more likely to find a jump from percentile 25th to 50th or from 5th to 10th with no mention to percentiles in between. This means that percentiles are generally clustered together in chunks of at least 5. Last (but definitely not " least"), we should note that, for practical reasons, percentiles are generally grouped together to avoid having too many categories. Especially at the extreme ends of the distribution, a significant increase in BMI would result in small change in percentile, whilst in the central values (the most common BMI values), a small change in BMI can result in a big change in percentile. It is important to note that the percentiles have a fixed amount of people in each group, but the BMI values for each group are not evenly spaced. For example, if he is in the 25th group with the lowest BMI, he is in the 25th percentile, which in turn means that he has a higher BMI than 25% of the population. The position of his group (from lowest to highest BMI) would determine his percentile. Now you are ready to classify any one individual in their percentile by simply assigning him to the corresponding groups according to his BMI. This way, you have made groups gathering 1% of the population each, also called percentiles. Then you should divide the data into 100 groups according to their BMI value, ensuring each group has the same number of individuals.

To understand it better, let's see the procedure you should follow if you were to create your own percentile for any statistic.įirst of all, you'd need to gather the data for all the people in your population group for this calculator, that would mean collection data of the BMI of men. To put it simply, percentiles are a quick way to compare one individual with the whole rest of the population. Percentiles are generally expressed as an ordinal number, which makes it more confusing. It is very common when we're talking about BMI (or any similar statistical value) to talk about percentiles. We will talk more about the connection between BMI and health in a later section. If you have a healthy BMI for men, you are only statistically more likely to be healthy than if you are outside of the normal BMI. The meaning of such a statement is that having a healthy BMI for men doesn't automatically mean that you are a healthy man.

It is important to point out that even WHO acknowledges that BMI is a statistical parameter. As mentioned previously, various organizations have different ways to group values of BMI for men, but most of the thresholds are the same or at a reasonable distance. In our calculations, we use the broadest of the BMI groupings for a total of 11 different BMI ranges for men. However, each of the categories can be subdivided to make distinctions between slight overweight and hyper-obesity on one end to slightly underweight and severely undernourished on the other. The division and categorization made by WHO leads to three major BMI ranges for males (as mentioned above: underweight, normal/healthy, and overweight). For the rest of the text, we will refer to the guidelines presented by the World Health Organization (WHO) on page 9 of their report: Obesity: preventing and managing the global epidemic. When it comes to setting up the different BMI ranges for men, there are almost countless options, which is very much the reason why there are several official ways to group normal BMI for males.
