Diet, Lifestyles, Family History, and Prostate Cancer Incidence in an East Algerian Patient Group

Abstract

Prostate cancer (PC) is the fourth most common cancer in men and the sixth leading cause of death in Algeria. To examine the relationship between lifestyle factors, including diet, and family history and PC risk, a case-control study was performed in an eastern Algerian population, comprising 90 patients with histologically confirmed PC and 190 controls. Data collection was carried out through a structured questionnaire and statistical analysis was performed to evaluate the different variables. The data showed that consumption of lamb and beef meat and high intake of animal fat and dairy products increased PC risk. Seven to thirteen vegetables servings per week and fourteen or more servings decreased PC risk by 62% and 96%, respectively. Seven to fourteen fruit servings per week decrease PC risk by 98%. Green tea consumption reduced the risk of PC but the results were statistically borderline. Increased risk was observed for individuals with family history of PC in first and in second degree. A positive strong association was also found for alcohol and smoking intake and a dose-response relationship existed for quantity and history of smoking. This study suggests that dietary habits, lifestyle factors, and family history have influence on the development of PC in Algerian population.

Latest Evidence on the Impact of Smoking, Sports, and Sexual Activity as Modifiable Lifestyle Risk Factors for Prostate Cancer Incidence, Recurrence, and Progression: A Systematic Review of the Literature by the European Association of Urology Section of Oncological Urology (ESOU)

“…On the contrary, when reviewing case-control studies (CCSs), only two studies did not find an impact on PCa incidence [28,29]: a study from Argentina found the same proportion of smokers in patients with PCa and controls [28]; also, May et al [20] did not find significant differences in the rate of advanced tumor stages between smokers and nonsmokers, while overall PCa risk was not evaluated. However, most CCSs found either an increased risk for PCa or more frequent high-grade PCa (HGPCA) and advanced stages in smokers [31][32][33][34][35][36][37].…”

“…The different results retrieved from cohort studies and CCSs may at least partially be explained by selection bias (men free of cancer at inclusion in cohorts vs PCa patients in CCSs), various smoking habits, and different smoking prevalence rates (eg, based on geographical regions) [31][32][33][34][35][36][37]. Only one CCS found a significantly reduced incidence in smokers [30].…”

Milk and Dairy Product Consumption and Prostate Cancer Risk and Mortality: An Overview of Systematic Reviews and Meta-analyses

“…Since the last meta-analysis of case-control studies, 3 additional primary studies have been carried out. In general terms, because they all used a different methodology, they all observed that milk or dairy product consumption increases prostate cancer risk (49)(50)(51). However, primary studies of cohorts observed that milk consumption did not show an association with total prostate cancer risk in adult men (52,53).…”

Food Label Literacy and Use among US Adults Diagnosed with Cancer: Results from a National Representative Study

“…The best strategies for delivering nutrition education interventions for all demographics need to be identified by researchers. The literature does show that physicians’ and other healthcare providers’ involvement could be key in food label use by primary care and specialty care patients [29, 41]; these professionals should make much of the fact that preventing cancer relapse is possible through lifestyle change [8, 28]. Augmenting such interpersonal healthful nutrition advocacy among cancer patients and survivors should be well-designed national campaigns.…”
