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 | Visceral fat (high waist-to-hip ratio) is linked to higher blood pressure through inflammation and sympathetic drive. | Non-drug BP management (opens in a new tab) |
| High cholesterol / dyslipidemia | Watch this | Moderate | Review / narrative | Visceral fat is linked to atherogenic dyslipidemia beyond overall weight. | Lifestyle & lipids (Endotext) (opens in a new tab) |
| Muscle & joint pain / weakness | Watch this | Moderate | Cohort / observational | Higher waist-to-hip ratio is associated with osteoarthritis even in non-weight-bearing hand joints (OR 1.45 in men), implicating systemic inflammation from visceral fat rather than load alone. | Adiposity & hand OA (NEO study) (opens in a new tab) |
| Osteoporosis / low bone density | Watch this | Emerging | RCT / meta-analysis | Higher waist-to-hip ratio is associated with higher hip-fracture risk (a 0.1-unit rise ~+3%); central fat harms bone quality despite higher BMD. | Obesity & bone metabolism review (opens in a new tab) |
| Peripheral neuropathy | Watch this | Moderate | Review / narrative | Visceral fat is a metabolic risk factor for peripheral neuropathy beyond overall weight. | Diabetic neuropathy review (opens in a new tab) |
| Reproductive & sexual health | Watch this | Moderate | Cohort / observational | Central/abdominal adiposity predicts reduced fertility partly independent of BMI, via insulin resistance and hormonal disruption. | Nutritional status & female infertility case-control (PMC11496271) (opens in a new tab) |
| Sleep-disordered breathing | Watch this | Moderate | Cohort / observational | Central/neck fat distribution predicts OSA beyond BMI alone. | OSA & obesity review (PMC10876414) (opens in a new tab) |
| Tinnitus | Watch this | Emerging | Cohort / observational | Visceral adiposity tracks with the vascular/metabolic risk linked to tinnitus - emerging. | Tinnitus & cardiovascular risk (opens in a new tab) |
| Type 2 diabetes & metabolic syndrome | Watch this | Strong | Review / narrative | Visceral fat (high waist-to-hip ratio) releases free fatty acids and inflammatory adipokines that cause insulin resistance; central to metabolic syndrome. | Diet & T2D prevention (Lancet) (opens in a new tab) |
| Weak immunity & chronic inflammation | Watch this | Moderate | Review / narrative | Higher waist-to-hip ratio marks visceral fat that fuels pro-inflammatory adipokines. | Central adiposity & CRP (opens in a new tab) |
| Cardiovascular | Watch this | Moderate | Cohort / observational | Waist-to-hip ratio was more strongly and consistently related to myocardial infarction than BMI across all ethnic groups (odds ratio 2.52, top vs bottom quintile). | INTERHEART study (waist-to-hip ratio, 52 countries) (opens in a new tab) |
| Cardiovascular | Watch this | Moderate | Cohort / observational | Higher waist-to-hip ratio was associated with all-cause and cardiovascular mortality in adults with diabetes. | Taiwan diabetes cohort (n=34,686) (opens in a new tab) |
| Endocrine & Metabolic | Watch this | Moderate | Cohort / observational | High waist-to-hip ratio reflects visceral fat and cardiometabolic risk. | Central-adiposity literature (opens in a new tab) |
| Liver, Kidney & Urinary | Watch this | Moderate | Cohort / observational | Central/abdominal adiposity is linked to fatty-liver and cardiometabolic-kidney risk. | Hypocaloric diet & hepatic steatosis (PMC12455765) (opens in a new tab) |
