Fruit and Vegetable Intake in Relation to Lower Urinary Tract Symptoms and Erectile Dysfunction Among Southern Chinese Elderly Men: A 4-Year Prospective Study of Mr OS Hong Kong
Abstract
The role of fruit and vegetable (FV) intake in relation to prostate health remains inconclusive. This 4-year longitudinal study aims to explore the association of FV intake and the development of lower urinary tract symptoms (LUTS, a cluster of chronic urinary symptoms occurring in bladder, prostate and urethra), incidence of symptomatic benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) in Chinese elderly men. Data were obtained from a 4 years longitudinal study (Mr OS Hong Kong, the largest prospective study on bone health in Chinese elderly). Two thousand Chinese men aged 65 years and older were recruited from the local community, of whom 1998 (99.9%) at baseline and 1564 (78.2%) at 4-year follow-up reported data on LUTS, which were evaluated by a validated International Prostate Symptoms Scale (IPSS). Erectile function was evaluated by the International Index of Erectile Dysfunction-5 (IIEF-5) questionnaires at 2- (n = 386) and 4-year (n = 475) follow-ups. Dietary intake was assessed using a validated food frequency questionnaire at baseline. Analysis was conducted using multivariate linear and logistic regression. For total FV and most of their subclasses, moderate consumption had the lowest mean changes of L...Continue Reading
