Analysis of the prevalence of voiding symptoms in Maori, Pacific Island, and Caucasian New Zealand men.
OBJECTIVE
Data from a community-based sample of 515 men were used to assess the prevalence and presentation of voiding symptoms in Caucasian, Maori, and Pacific Island men in the city of Porirua, New Zealand.


METHODS
A random sample, stratified by age groups of 10 years, was obtained for men 40 years and older. Two hundred men were entered into each 10-year age stratum. Frequency of symptoms and quality of life were measured using the International Prostate Symptom Score (IPSS) questionnaire. Bothersomeness of symptoms was assessed using questions from the American Urological Association symptom bother index. Data were analyzed according to age and ethnic group with differences between groups measured by analysis of variance.


RESULTS
Symptom score was found to increase with increasing age of subjects, with men in the 40 to 49 years age group recording a mean score (+/- SE) of 2.9 +/- 0.3, increasing to a mean score of 4.8 +/- 0.4 for men aged 50 to 59 years, 7.4 +/- 0.9 for men aged 60 to 69 years, and 7.4 +/- 0.9 for men in the 70 year and older age group. Significant symptoms, represented by a symptom score of 8 or greater, were found in 12.9% of men aged 40 to 49 years, 22.3% of men aged 50 to 59 years, 33.7% of men aged 60 to 69 years, and 33.3% in the 70 year and older age group. No difference was demonstrated in the prevalence of symptoms between Caucasian, Maori, and Pacific Island men.


CONCLUSIONS
Despite having a similar prevalence of voiding symptoms to Caucasian men, few Maori or Pacific Island men seek help for their urinary symptoms. The level of understanding of the underlying disease process is poor for men of all ethnic backgrounds and emphasizes the important need for greater public awareness and education with respect to prostate disease.
