Prospective study of adiposity and weight change in relation to prostate cancer incidence and mortality,,

CANCER, Issue 4 2007
Margaret E. Wright PhD
Abstract BACKGROUND. Adiposity has been linked inconsistently with prostate cancer, and few studies have evaluated whether such associations vary by disease aggressiveness. METHODS. The authors prospectively examined body mass index (BMI) and adult weight change in relation to prostate cancer incidence and mortality in 287,760 men ages 50 years to 71 years at enrollment (1995,1996) in the National Institutes of Health-AARP Diet and Health Study. At baseline, participants completed questionnaires regarding height, weight, and cancer screening practices, including digital rectal examinations and prostate-specific antigen tests. Cox regression analysis was used to calculate relative risks (RR) and 95% confidence intervals (95% CIs). RESULTS. In total, 9986 incident prostate cancers were identified during 5 years of follow-up, and 173 prostate cancer deaths were ascertained during 6 years of follow-up. In multivariate models, higher baseline BMI was associated with significantly reduced total prostate cancer incidence, largely because of the relationship with localized tumors (for men in the highest BMI category [,40 kg/m2] vs men in the lowest BMI category [<25 kg/m2]: RR, 0.67; 95% CI, 0.50,0.89; P = .0006). Conversely, a significant elevation in prostate cancer mortality was observed at higher BMI levels (BMI <25 kg/m2: RR, 1.0 [referent group]; BMI 25,29.9 kg/m2: RR, 1.25; 95% CI, 0.87,1.80; BMI 30,34.9 kg/m2: RR, 1.46; 95% CI, 0.92,2.33; and BMI ,35 kg/m2: RR, 2.12; 95% CI, 1.08,4.15; P = .02). Adult weight gain from age 18 years to baseline also was associated positively with fatal prostate cancer (P = .009), but not with incident disease. CONCLUSIONS. Although adiposity was not related positively to prostate cancer incidence, higher BMI and adult weight gain increased the risk of dying from prostate cancer. Cancer 2007.

Geriatricians Health Survey 2000

JOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 11 2001
David Watts MD
OBJECTIVES: To characterize geriatricians' preventive health behaviors including vitamin/supplement use, exercise, smoking, alcohol use, and weight control. DESIGN: Mailed questionnaire. SETTING: United States. PARTICIPANTS: Two thousand six hundred eleven U.S. physicians certified as having added qualifications in geriatric medicine and who were members in the American Geriatrics Society; 1,524 returned completed questionnaires (58%). MEASUREMENTS: Rates of supplement use and recommendations, preventive health visits, advance directive completion, exercise, religious service attendance, smoking, alcohol use, and amount of adult weight gain. RESULTS: Most responding geriatricians took at least one vitamin supplement: 50% vitamin E, 50% a multivitamin (MVI), and 31% vitamin C. Calcium ingestion was common among women. Other supplement use was uncommon: ginkgo compounds were consumed by 47 (3%), and 77 (5%) took a variety of other nonvitamin supplements. Over 90% recommended vitamins, especially multivitamins and vitamin E, at least sometimes. Recommendations for ginkgo (38%) and St. John's wort (33%) were also common. Almost half of respondents had completed a formal advance directive. Exercise was practiced at least weekly by 88%. Cigarette smoking was rare (1%), but at least occasional alcohol use was common (85%). Most of respondents were men (74%), and 35% had completed fellowship training. CONCLUSION: Vitamin/supplement use was common among responding geriatricians but not universal. Respondents often recommended MVI, vitamin E, and vitamin C, but were less likely to consume or recommend other supplements. The most common preventive health behavior among our respondents was exercise. [source]

The Relationship between Obesity and Breast Cancer Risk and Mortality

NUTRITION REVIEWS, Issue 2 2003
Article first published online: 16 SEP 200
Obesity is an established risk factor for postmenopausal, but not premenopausal, development of breast cancer. Evidence for a positive association between obesity and breast cancer mortality is mounting. Avoiding adult weight gain and maintaining a healthy body weight may contribute importantly to decreasing breast cancer risk and mortality, especially in postmenopausal women. [source]
