Kidney stones are becoming more common in the U.S., especially amongst teens, females as well as African-Americans, found a new study just published.
Researchers analyzed information from close to 153,000 adolescent and adult patients with kidney stones, from a population of more than 4.6 million.
Overall, the annual kidney stones occurrence rate increased by 16% from 1997 to 2012. The greatest increase was amongst adolescents with a growth of 4.7% each year, females at 3% each year and African-Americans at 2.9% annually.
From 1997 to 2012, risk of developing kidney stones doubled for girls and boys during childhood, while it increased by 45% over the lifetime for women.
The highest increase in the development of kidney stones was amongst adolescent females. In any of the years studied, kidney stones were more prevalent amongst females than males between the ages of 10 and 24.
After the age of 25, kidney stones become more common amongst men. Amongst African Americans, there was an increased in the cases of kidney stones 15% more often than amongst whites within each of the five-year periods during the study.
One doctor in Philadelphia said that the emergence of kidney stones amongst children has become worrisome since there is little evidence as to what the best way is to treat the child that has the condition.
Possible reasons for the increase in the number of kidney stones cases might include poor drinking water and poor dietary habits like an increase in the intake of sodium and a lowering in the amount of calcium taken, said researchers.
In addition, dehydration, which is one of the factors that promote growth of kidney stones, is linked to both higher temperatures and poor ingestion, said researchers.
The findings have been published in the Clinical Journal of American Society of Nephrology.
