Abstract: 

Back ground: Prostate cancer is the most frequent cancer among males in economically developed countries.
Among the several risk factors that have been suggested for prostate cancer, only age, ethnicity, and family history of prostate cancer are well-established and primary prevention of this disease is limited. Prior studies had shown that dietary intake could be modified to reduce cancer risk.
Most of the data in this area have been drawn from Western world studies and there isn’t enough published data about dietary pattern and cancers in developing countries. We conducted this study to examine the association between Cabbage intake and the risk of prostate cancer in Iran.
Methods: We conducted a hospital-based, case–control study to examine the association between Cabbage intake and the risk of prostate cancer in Iran. Cases were patients aged 40–78 years who were admitted to ‘Labbafi-Nejad Hospital’ with incident, histologically confirmed cancers of the prostate. Cases were diagnosed not before 6 months of the interview, with no history of cancers of other sites. Controls were patients (43-71years) who were admitted to the emergency service of the same hospital without neoplastic conditions and long-term modification of diet. Cases and controls were frequency matched according to the age (10-year groups). A total of fifty patients with prostate cancer and a hundred controls underwent face-to-face interviews.
We assessed participants’ dietary intakes during the past year by using a valid and reliable semi-quantitative food frequency questionnaire (FFQ). This FFQ consists of 168 food items with standard serving sizes, and we asked participants to specify their consumption frequency for each food item on a daily, weekly, monthly or yearly basis. We converted these data to daily frequencies and then to the daily grams of food intake, using the manual for household measures. Proportional hazards regression methods were used to assess the associations between Cabbage intake and prostate cancer risk. The SPSS version 16 was used for analyzing the data.
Results: We observed a strong significant inverse association between Cabbage intake and the risk of prostate cancer (high 2nd median vs. low 1st median, OR=0.12, 95% CI =0.04- 0.39).
Conclusion: The results of the present study suggested that Cabbage intake might be associated with prostate cancer. We can suggest intake of Cabbage to prevent the incidence of prostate cancer.
