Abstract
To estimate the prevalence of urinary stone disease in Koreans, and to determine
the inter-relationships between urinary stone disease and various
epidemiological factors, 1,521 controls and 1,177 cases with urinary stones were
evaluated. Of special interest in this study were: 1) proportion of past urinary
stone history among controls; 1.9% 2) the point prevalence rate of urinary
stones among controls; 0.2% 3) the recurrence rate of urinary stones (the
proportion of past history of urinary stone) among cases; 56.8% 4) high
incidences (76.3%) in the thirties to the fifties among cases 5) the risk
factors for urolithogenesis; obesity [higher than 25 of BMI (body mass index,
weight/height2)], more than 10 year-experience as a production worker, past
stone history, familial stone history, low physical activity (< 2,000 Kcal/day),
and low intake of fruit. However, the well-known risk factors for urinary
stones; over intake of meat or fish and milk or dairy products, perspiration,
amount and kind of drinking water, and stress unexpectedly were not
significantly different between the controls and the cases.
