Why is BMI linked to insurance risk scoring?

The connection between Body Mass Index and insurance risk assessment is that it provides insurance companies with some fundamental information about the general health status of the insured individual.

Being exceptionally high or exceptionally low, a person's Body Mass Index may sometimes indicate underlying diseases that can raise the likelihood of being hospitalised, requiring prolonged care, or developing lifestyle-based diseases. On the other hand, Body Mass Index may never be considered alone but in conjunction with other elements such as age or smoking habits.

What does BMI mean in Health Insurance?

BMI or Body Mass Index is a mathematical equation formulated using the height and weight of a person. This is usually used to determine whether a person belongs to a certain category, like being underweight, healthy weight, overweight, or obese.

Health insurance providers normally consider BMI while underwriting. Underwriting involves the evaluation done by insurers before issuing any insurance policy or deciding premiums.

Usually, BMI can assist insurers in determining the probability of future medical costs associated with ailments like:

• High Blood Pressure


• Type 2 Diabetes


• Heart Ailments


• Sleep Apnoea


• Joint Disorders


• Fatty Liver Disease
  

This does not imply that all individuals with high BMI values will be unhealthy in the future.

How can BMI affect Insurance Premiums?

An individual with a BMI out of the ordinary range might be subject to a higher premium on certain occasions. This could be due to the probability of insurance claims in some cases being high.

The final premium will always depend on a number of factors and not solely on BMI. Some insurance companies may also require the individual to undergo physical tests before issuing a policy.

Why Do Insurers Not Rely Only On BMI?

While BMI is easy to calculate, there are certain drawbacks associated with it.

For example, BMI does not include:

• Body muscle composition


• Percentage body fat


• Fitness level


• Physical activity


• Eating habits
  

In other words, an athlete or someone who has larger muscles may register a high BMI even when they are in great physical shape. The same could be said about any person with a normal BMI who might have different medical conditions.

To make their decisions more justified, most insurance companies take into account:

• Any preexisting conditions


• Medical background


• Smoking and drinking habits


• Results from blood tests


• Blood pressure measurements


• Lifestyle habits

This wider analysis helps the insurer make a more balanced decision rather than just relying on BMI.

Can a High BMI Lead to Policy Rejection?

Not necessarily. Most people who have high BMI can still be able to purchase insurance policies for their healthcare. On the other hand, the insurer can decide to do one or all of the following:

• Charge higher premiums


• Insert waiting periods for some illnesses


• Conduct some medical tests


• Provide insurance cover under some conditions

The outcome depends on the insurer’s underwriting policy and the individual’s overall health condition.

Does Reducing BMI Help in the Future?

A healthy way of living could possibly improve your state of health. In certain situations, insurance companies may assess health conditions when renewing their policies or even when getting a fresh policy in the future.

Physical exercise, proper eating, and regular visits to the doctor could possibly help avoid diseases that arise from unhealthy ways of living. However, this will be influenced by underwriting rules, medical examination, and other factors.

The coverage and premium for the health insurance can differ depending on the insurance company, as well as medical underwriting, policy wording, and disclosure of health conditions. You should carefully study the wording of the policy.
