To estimate the association between body mass index (BMI: kg/m2) and prostate-specific antigen (PSA) cancer screening in a nationally representative sample of US men aged 50 years and older using data from the 2001 Behavioral Risk Factor Surveillance Survey.
Men aged 50 years or older classified by BMI as healthy weight range (18.5-24.9), overweight (25-29.9), obese class I (30-34.9), obese class II (35-39.9), and obese class III (> or =40).
Interval since most recent screening for PSA.
Adjusting for age, race, smoking, education, employment, income and health insurance status, we found that, compared with men in the healthy weight range, men in the overweight [odds ratio (OR)=1.13; 95% confidence interval (95% CI)=1.04-1.35], obese class I (OR=1.26; 95% CI=1.06-1.36) and obese class II (OR=1.14, 95% CI=1.02-1.26) categories were significantly more likely to have obtained a PSA test within the previous year. A similar pattern was observed when we examined other screening intervals (e.g. within past 2 years, within past 3 years, etc.).
Among men aged 50 years and older, overweight and obesity is associated with obtaining a PSA test.

    • "Four studies examined the association between obesity and prostate cancer screening, and all used prostate-specific antigen (PSA) testing as their outcome. Three of the four studies indicated that obese men were more likely to have had a PSA test [9] [10] [11] when compared with their normal-weight peers. One study examined obesity and PSA testing in a cohort of men from primary care practices and found a consistent association with obesity and increased PSA testing, regardless of race [10] "

    ABSTRACT: The relationship between obesity and cancer screening varies by screening test, race, and gender. Most studies on cervical cancer screening found a negative association between increasing weight and screening, and this negative association was most consistent in white women. Recent literature on mammography reports no association with weight. However, some studies show a negative association in white, but not black, women. In contrast, obese/overweight men reported higher rates of prostate-specific antigen (PSA) testing. Comparison of prostate cancer screening, mammography, and Pap smears implies a gender difference in the relationship between screening behavior and weight. In colorectal cancer (CRC) screening, the relationship between weight and screening in men is inconsistent, while there is a trend towards lower CRC screening in higher weight women.

    ABSTRACT: Prostate cancer is the most common malignancy in men. Mortality due to prostate cancer has continued to increase over the past five decades despite all the different options of treatment at the disposal of the urologist, such as, surgery, radiotherapy, chemotherapy and biotherapy. Presently, effective therapy for prostate cancer is only possible with early diagnosis of the disease still localised within the prostate. Recent studies have demonstrated that the present screening techniques including Digital Rectal Examination (DRE), Serum Prostate Specific Antigen (PSA) concentration, Transrectal Ultrasound (TRUS) and Random Ultrasonically guided multiple prostatic biopsies can detect some potentially curable asymptomatic localised cancers. The main goal of a cancer screening test is to help reduce mortality. To date, it has been established that screening increases early detection and survival but there is no evidence that screening reduces mortality. If in future early detection and intervention is proved to provide real benefit apart from the overdiagnosis of latent non aggressive tumours, then the mortality from prostate cancer could begin to decline in the next decade. However, if our current armamenteria of therapies continue to be ineffective in treating men with prostate cancer, the current emphasis on screening and early detection will decline.
