بررسی ارتباط شاخص توده بدنی با سطح سرمی آنتی ژن اختصاصی پروستات (PSA) در مردان 40 تا 79 ساله مراجعه کننده به آزمایشگاه بیمارستان حضرت رسول (ص)

 Background: The level of Prostate-Specific Antigen (PSA) in identifying patients at high risk for prostate cancer has always been a controversial issue. This study was designed in order to assess the relationship between PSA levels with age and Body Mass Index (BMI) in symptom free men. Methods: In this cross sectional study, demographic data and PSA levels in 180 men referred to Rasoul Akram Hospital with analysis, data description, chi-square and correlation tests with SPSS software were used. Results: The mean age of men was 60.7±9 years and the mean of BMI was 26.1±3.5 kg/m2. This study showed inverse correlation between PSA and BMI which was very low and insignificant (p=0.141). But the correlation between PSA and age were significant and positive. Conclusion: This study showed there is no correlation between PSA and BMI. However studies which have been conducted in symptomatic patients have shown a correlation between PSA and BMI. This may result from PSA level above 10 and leading to the ambiguity that it is perhaps due to high levels of PSA.
