Key result

Ultrasound-measured abdominal wall fat index is independently linked to carotid intima-media thickness in non-obese men.

  • β 0.0538
  • 95% CI 0.0116-0.0960
  • P=0.013
  • n=297

Why the study?

The association between visceral fat accumulation assessed by ultrasonography and common carotid atherosclerosis in non-obese men was unclear.

Is the abdominal wall fat index (AFI) associated with carotid intima-media thickness in non-obese men?

Population

297 consecutive non-obese male in-patients aged 16 to 79 years

Comparison

Abdominal wall fat index (Pmax/Smin ratio) as exposure

Design

Cross-sectional ultrasonographic study

Implication

Does not support clinical adoption of ultrasonographic abdominal fat index; hypothesis-generating for its link to carotid atherosclerosis in non-obese men.

Study Design

Type

Cross-Sectional (n=297)

Multicenter

No

Structured PICO

Is the abdominal wall fat index (AFI) associated with carotid intima-media thickness in non-obese men?

P
Population
297 non-obese male in-patients (mean age 65 years, BMI 18.5-25 kg/m2) evaluated cross-sectionally for the association between ultrasonographic abdominal wall fat index and carotid atherosclerosis.
E
Exposure
Abdominal wall fat index (AFI) assessed by ultrasonography (ratio of maximal thickness of peritoneal fat to minimal thickness of subcutaneous fat)
O
Outcome
Intima-media thickness (IMT) of the common carotid arterysurrogate

Main Result

Effect estimate: β 0.0538 (95% CI 0.0116-0.0960)

p-value: p=0.013

The abdominal wall fat index measured by ultrasonography is independently associated with carotid atherosclerosis in non-obese men.

Limitations

  • Study population limited to male in-patients
  • Cross-sectional design limits causal inference

Cite This Study

Kawamoto et al. (2005) conducted a cross-sectional in Carotid Atherosclerosis (n=297). Abdominal Wall Fat Index (AFI) vs. Lower AFI was evaluated on Carotid intima-media thickness (IMT) (β 0.0538, 95% CI 0.0116-0.0960, p=0.013). Abdominal wall fat index assessed by ultrasonography was a significant independent predictor of common carotid intima-media thickness (β 0.0538) in non-obese men.
