Relationship among diet habit and lower urinary tract symptoms and sexual function in outpatient-based males with LUTS/BPH: a multiregional and cross-sectional study in China.
BMJ Open 2016; 6(8):e010863BO

Abstract

OBJECTIVES

This study assessed the effect of diet habits on lower urinary tract symptoms (LUTS) and sexual function in Chinese men with LUTS/benign prostatic hypertrophy (LUTS/BPH).

SETTING

Multicentre study conducted between July 2013 and December 2013 in 11 hospitals in 3 geographic regions in China.

PARTICIPANTS

Overall, participants with LUTS/BPH accounted for 61.4% (2584/4208) of the respondents, whose data were processed in the following statistical analysis.

PRIMARY AND SECONDARY OUTCOME MEASURES

LUTS and sexual function were assessed based on the International Prostate Symptom Score (IPSS) and the International Index of Erectile Function 5 (IIEF-5) score. Prostate volume (PV) was determined by ultrasound.

RESULTS

A total of 4208 participants met the inclusion criteria. The average age of the whole participants was 65.8±7.7 years. Overall, participants with LUTS/BPH accounted for 61.4% (2584/4208) of the respondents, whose data were processed in the following statistical analysis. Generally, prostate enlargement was greatest in south China. LUTS and male sexual dysfunction (MSD) were most severe in northwest China. Based on multivariable analysis, PV enlarged as the age (p<0.001), body mass index (BMI; p<0.001) and vegetable intake (p<0.001) increased. Age (p<0.001) and BMI (p<0.05) independently increased the IPSS. A higher level of education (p<0.001) and more frequent meat, fish and egg intake (p<0.05) decreased the IPSS. Age (p<0.001), BMI (p<0.001), low education level (p<0.05), vegetable intake (p=0.001), and milk and dairy product intake (p=0.001) decreased the IIEF-5 score.

CONCLUSIONS

In addition to factors including age, obesity and level of education, dietary habits and geographic difference might also play an important role in the variation of PV, LUTS and MSD for Chinese men with LUTS/BPH.
