What this is linked to
| Condition or system | Direction | Strength | Evidence type | What was found | Source |
|---|---|---|---|---|---|
| High blood pressure | Watch this | Moderate | RCT / meta-analysis | Body-shape indices capturing central adiposity flag blood-pressure risk that BMI can miss. | Non-drug BP management (opens in a new tab) |
| High cholesterol / dyslipidemia | Watch this | Moderate | Review / narrative | Body-shape indices capturing central adiposity flag dyslipidemia risk. | Lifestyle & lipids (Endotext) (opens in a new tab) |
| Muscle & joint pain / weakness | Watch this | Moderate | Cohort / observational | Body Roundness Index and related visceral-fat indices are associated with osteoarthritis; visceral fat secretes pro-inflammatory adipokines that degrade cartilage independent of BMI. | Visceral adiposity indices & OA (opens in a new tab) |
| Osteoporosis / low bone density | Watch this | Emerging | Cohort / observational | Body-shape indices capturing central adiposity are inversely associated with femoral bone density, flagging visceral-fat-driven skeletal fragility that BMI can mask. | Body-shape index & BMD (NHANES) (opens in a new tab) |
| Peripheral neuropathy | Watch this | Moderate | Review / narrative | Body-shape indices capturing central adiposity flag metabolic neuropathy risk. | Diabetic neuropathy review (opens in a new tab) |
| Reproductive & sexual health | Watch this | Emerging | Cohort / observational | Central-adiposity indices flag the fat distribution linked to hormonal and ovulatory disruption. | Nutritional status & female infertility case-control (PMC11496271) (opens in a new tab) |
| Sleep-disordered breathing | Watch this | Moderate | Cohort / observational | Central-adiposity indices flag the fat distribution most relevant to OSA risk. | OSA & obesity review (PMC10876414) (opens in a new tab) |
| Tinnitus | Watch this | Emerging | Cohort / observational | Body-shape measures of central fat flag the metabolic risk associated with tinnitus - emerging. | Tinnitus & cardiovascular risk (opens in a new tab) |
| Type 2 diabetes & metabolic syndrome | Watch this | Strong | Review / narrative | Body-shape indices reflecting central adiposity track insulin resistance and metabolic-syndrome risk better than weight alone. | Diet & T2D prevention (Lancet) (opens in a new tab) |
| Weak immunity & chronic inflammation | Watch this | Moderate | Review / narrative | Central-adiposity measures track systemic inflammation (IL-6/CRP) and immune dysfunction. | Central adiposity & CRP (opens in a new tab) |
| Endocrine & Metabolic | Watch this | Moderate | Cohort / observational | Higher BRI reflects visceral adiposity and cardiometabolic risk. | "Body Roundness Index Associated With Cardiometabolic Multimorbidity and Mortality: A Multistate Analysis", Obesity 2025 (opens in a new tab) |
| Cardiovascular | Watch this | Moderate | Cohort / observational | BRI showed a U-shaped association with all-cause mortality, with elevated cardiovascular risk at high values. | BRI and mortality (JAMA Network Open 2024) (opens in a new tab) |
| General / Whole-body Energy | Watch this | Emerging | Cohort / observational | Both very high and very low BRI were associated with higher all-cause mortality (U-shaped). | BRI and all-cause mortality (JAMA Network Open 2024) (opens in a new tab) |
| Liver, Kidney & Urinary | Watch this | Emerging | Cohort / observational | Central-adiposity indices flag the visceral fat that drives fatty liver and metabolic-kidney risk. | Hypocaloric diet & hepatic steatosis (PMC12455765) (opens in a new tab) |
