Compare your head size to average head sizes and head-to-body mass ratios, then analyze how your measurements stack up against percentiles and averages, considering the implications of head circumference and body proportions and gain insights into body composition and anthropometry.
1. Understanding Head Size: What Is Considered Normal?
Figuring out what head size is “normal” involves a combination of measurements and relative proportions. Head circumference and the ratio of head size to body size are key factors in determining whether your head size is within the typical range. Now, let’s dive into how to calculate head mass and head-to-body mass ratio.
1.1. Measuring Head Size: Calculating Head Mass
Calculating head mass from a DXA scan involves subtracting the mass of other body regions from the total body mass. This can be done using the formula: Head mass = total mass – total mass of arms – total mass of legs – total mass of trunk. This provides a precise measurement that can be compared to percentile charts.
To calculate your head mass, follow these steps:
- Obtain your BodySpec DXA scan results.
- Locate the Regional Assessment section on the first page.
- Apply the formula: Head mass = Total mass – Total mass of arms – Total mass of legs – Total mass of trunk.
For instance, if the total mass is 135.8 lbs, arm mass is 16.6 lbs, leg mass is 54.0 lbs, and trunk mass is 55.3 lbs, the head mass would be calculated as follows: Head mass = 135.8 lbs – 16.6 lbs – 54.0 lbs – 55.3 lbs = 9.9 lbs.
1.2. Relative Head Size: Head-to-Body Mass Ratio
The head-to-body mass ratio offers a relative perspective on head size. This is calculated by dividing head mass by total body mass. Even if the absolute head size isn’t particularly large, a high head-to-body mass ratio can give the impression of a larger head relative to the body.
Calculating the head-to-body mass ratio is straightforward:
- Divide the head mass by the total body mass.
- Express the result as a percentage.
For example, if the head mass is 9.9 lbs and the total body mass is 135.8 lbs: Head to body mass ratio = 9.9 lbs / 135.8 lbs = 7.29%. This indicates that the individual’s head comprises 7.29% of their total body mass.
1.3. Percentile Charts: How Do You Compare?
Percentile charts help contextualize head mass and head-to-body mass ratio by showing how an individual’s measurements compare against a broader population. These charts typically provide data segmented by gender, offering a clearer picture of where someone falls within the spectrum.
Percentile charts are organized to show the distribution of head mass and head-to-body mass ratios. To use these charts effectively:
- Locate your gender on the chart.
- Find the range that includes your calculated head mass or head-to-body mass ratio.
- Identify the corresponding percentile range to see how you compare to others.
For example, a head mass of 9.9 lbs for a male would fall in the 0% – 20% percentile range, indicating a relatively small head. However, for a female, a head mass of 9.9 lbs would be in the 60% – 80% percentile range, suggesting a larger than average head.
