Abstract
PURPOSE: We prospectively evaluated the association between adiposity and the risk of lower urinary tract symptoms incidence and progression in the Health Professionals Followup Study (HPFS). MATERIALS AND METHODS: At baseline participants reported current height and weight, and weight at age 21 years. A year later they reported waist and hip circumferences, and every 2 years thereafter they reported weight. Participants periodically completed the International Prostate Symptom Score (I-PSS) and reported surgery or medication use for lower urinary tract symptoms. We used Cox proportional hazards regression to estimate the multivariable adjusted association between adiposity and lower urinary tract symptoms incidence and progression. The incidence analytical cohort of 18,055 men had no lower urinary tract symptoms at baseline. A total of 6,461 men entered the progression analytical cohort when they first experienced lower urinary tract symptoms. RESULTS: The risk of lower urinary tract symptoms in 4,088 cases increased with increasing body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.61, 95% CI 1.31-1.99), waist circumference (greater than 42 inches vs 33 or less HR 1.39, 95% CI 1.19-1.63) and weight gain since age 21 years (50 pounds or greater vs stable weight HR 1.31, 95% CI 1.17-1.46, each p trend <0.0001). The risk of lower urinary tract symptom progression in 1,691 cases increased with body mass index (35 kg/m(2) or greater vs 23 to less than 25 HR 1.44, 95% CI 1.04-2.00, p trend <0.0001), weight gain since age 21 years (50 pounds or greater vs stable weight HR 1.35, 95% CI 1.14-1.60, p trend <0.0001) and waist circumference (greater than 42 inches vs 33 or less HR 1.32, 95% CI 0.95-1.85, p trend 0.005). CONCLUSIONS: Men with higher total and abdominal adiposity and those who gained weight were more likely to have lower urinary tract symptoms develop or progress. Our findings support the notion that obesity may be an important target for lower urinary tract symptom prevention and intervention.
