information

Interpretation:

Hazard Ratio is a statistical measurement used to define the frequency of an outcome event in one group versus another, over a given period of time. 

In a recent study by Zhang et al, the period of time was 20 years.

pearls

• Comparable to or better than BMI and waist-to-hip ratio in estimating percent body fat and total percent visceral adipose tissue.
• Potentially superior in predicting the risk of mortality and cardiometabolic disease.

usecase

Employed in routine health screenings to assess body shape and estimate body fat, identifying individuals at increased risk of obesity-related conditions (e.g., cardiometabolic disease) and all-cause mortality.

reasons

Fat distribution, particularly visceral fat, is closely tied to cardiovascular disease and all-cause mortality. This may not be accurately reflected by other tools such as BMI.

next_advice

• Higher BRI values indicate a more spherical body shape, associated with higher visceral fat and increased metabolic risk.
• Some studies have shown that a very low BRI (<3.4) is also associated with elevated all-cause mortality, particularly in individuals ≥65 years of age.
• For individuals identified with high BRI values:
  
  • Further diagnostic screenings (e.g., lipid profile, fasting glucose) may be recommended.
  • Discuss lifestyle modifications (e.g., diet, exercise).
• Regularly monitor to assess the effectiveness of interventions and changes in BRI over time.
