Key result

Increased body mass index was associated with statistically significant increases in liver, spleen, kidney, and heart weights, with differential cardiac effects between men and women.

Why the study?

How do body mass index and age affect organ weights in an older autopsy population?

Population

300 medical autopsy reports of older individuals with multiple comorbidities

Design

Cohort

Implication

Updated BMI-adjusted organ weight references may aid autopsy interpretation; leaves open prospective validation in comorbid populations.

Key Points

  • To evaluate the impact of obesity and age on organ weights in older individuals with multiple comorbidities.
  • Retrospective review of 300 medical autopsy reports
  • Analysis of organ weights in relation to body mass index and age
  • Comparison across genders for heart and thyroid parameters.
  • Significant increase in organ weights with body mass index, decrease with age for liver, spleen, and kidneys.
  • In men, increased age linked to higher left ventricular wall thickness; increased BMI linked to greater heart weight.
  • In women, only BMI affected heart parameters, with no age effects observed.

Type

Observational (n=300)

Structured PICO

How do body mass index and age affect organ weights in an older autopsy population?

P
Population
300 medical autopsy reports from a general population of older individuals with multiple comorbidities.
O
Outcome
Organ weights (liver, spleen, kidneys, heart, thyroid) and cardiac parameters (ventricular wall thickness)surrogate

Increased BMI is associated with increased heart weight and ventricular wall thickness in women, suggesting obesity may have a greater impact on cardiovascular causes of death in women than men.

Cite This Study

Mandal et al. (2012) conducted an observational in Medical autopsy population with multiple comorbidities (n=300). Body mass index (BMI) and age was evaluated on Organ weights (liver, spleen, kidneys, heart, thyroid). Increased body mass index was associated with statistically significant increases in liver, spleen, kidney, and heart weights, with differential cardiac effects between men and women.
