What is the CMS standard for BMI for those aged 65 and older?

The Centers for Medicare & Medicaid Services (CMS) have established specific guidelines regarding body mass index (BMI) for older adults, particularly those aged 65 and older. The correct standard indicates that a BMI range of 23 to 30 kg/m^2 is considered appropriate for this age group.

This range acknowledges that older adults may have different health implications related to weight compared to younger populations. Research has shown that a slightly higher BMI in older adults can be associated with better overall health outcomes, as it may include more muscle and fat reserves that can help prevent frailty, particularly in the context of age-related conditions. Therefore, the chosen range reflects an understanding of how body composition changes with age and the need to tailor health standards accordingly.

In contrast, other ranges, such as those offering lower upper limits (like 24.9 or 29.9), do not align with the current evidence and recommendations for older individuals. These ranges could potentially misclassify older adults' health status and overlook the complexities of aging in relation to body weight and health risks.
