膳食钠盐、体质量指数与良性前列腺增生关系的研究
Association of dietary sodium intake,body mass index with clinical benign prostatic hyperplasia
摘要
Abstract
Objective To examine the association between dietary sodium intake,body mass index(BMI)and clinical benign prostatic hyperplasia(BPH)risk in older men. Methods A hospital based case control study was conducted. Cases(n=360)were men with histologically confirmed BPH,and controls(n=360)were men,admitted to hospital for many different diseases which not relat ed with prostatic conditions. Case and control were matched with 1∶ 1. Using a standardized structured questionnaire, all subjects were interviewed to measure body height and weight. Data on diet were obtained via a food frequency questionnaire. The odds ratios (OR)and 95％ confidence intervals(CI)of BPH for dietary sodium intake and BMI were estimated using unconditional multiple logistic regression models. Results Dietary sodium intake(15.39±3.17)g/d in cases was obviously more than the controls(14.67±3.07)g/d. Dietary sodium was the highest among 55 to 59 years old. Compared to the controls,dietary sodium intake was higher in cases,with increase of the cases' age. After adjusted for energy,dietary sodium intake was positively related to clinical BPH(χ2=12.095 ,P=0.007). The odds of BPH significantly increased with increasing dietary sodium intake. Men in the highest quartile of dietary sodium intakes were nearly twice as likely to report BPH(OR=1.827,95％CI:1.206～2.769,P=0.004).Conclusion Dietary sodium intake is positively associate with BPH. A high intake of dietary sodium might be a risk factor of clinical BPH.关键词
