The Claim
Body mass index increases with age in healthy urban ethnic Kazakh adults, with men exhibiting a rise from approximately 23.5 kg/m² at ages 20–29 to 26.2 kg/m² at ages 50–59, and women exhibiting a rise from approximately 21.4 kg/m² to 23.8 kg/m².
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy urban ethnic Kazakh adults, body mass index rises with age. Men's average BMI increases from about 23.5 to 26.2 between ages 20–29 and 50–59. Women's average BMI increases from about 21.4 to 23.8 over the same age range.
See the scientific wording
Body mass index increases with age in healthy urban ethnic Kazakh adults, with men showing a rise from approximately 23.5 kg/m² at ages 20–29 to 26.2 kg/m² at ages 50–59, and women from 21.4 kg/m² to 23.8 kg/m², indicating a consistent age-related trend toward higher body weight relative to height.
As people get older, their bodies burn fewer calories at rest and they move less, so they store more fat. This extra fat makes them heavier without changing their height, so their weight-to-height ratio goes up.
What the research says
1 studyThis study found that as people get older, their body mass index (BMI) tends to go up — meaning they generally weigh more compared to their height. This matches what the claim says about aging and weight gain.
