Hypothesis

There might be differences in perception of IC symptoms, risk factor occurrence and extent of leg artery atherosclerosis between men and women that may influence diagnosis.

Conclusion

Sex differences in the description of IC symptoms may influence diagnosis even if objective features of PAD are similar.

Supporting Evidence

  • Men with IC had more cardiovascular disease and a more profound smoking history than women.
  • Women reported a lower walking speed and more joint problems.
  • Women more often reported atypical IC symptoms despite similar ABI and walking ability.

Takeaway

Men and women experience different symptoms of leg pain when they have a condition called intermittent claudication, which can affect how doctors diagnose them.

Methodology

Cohort study with 5040 elderly subjects measuring ABI and collecting questionnaire data on medical history and symptoms.

Potential Biases

Potential under-diagnosing of IC in women due to atypical symptoms.

Limitations

Few statistically significant differences were observed, possibly due to small cohort size in follow-up.

Participant Demographics

Elderly subjects aged 60-90 years, with a median age of 71.

Statistical Information

P-Value

P = 0.09 for prevalence of IC between sexes; P < 0.01 for lower walking speed in women.

Confidence Interval

CI 6.5-7.1 for prevalence of IC.

Statistical Significance

p<0.05
