Caffeine as a Probable Factor for Increased Risk of OAB Development in Elderly People

This study was conducted to compare overactive bladder (OAB) prevalence among people greater than 60 years of age who intake various doses of caffeine, as well as those who abstain from caffeine.

A randomized observational study was carried out in Vladivostok Gerontological Hospital. A total of 1,098 retired people greater than 60 years of age (659 women and 439 men, average age 67.1 years) took part in the study. They were admitted to the in-patient department with the purpose of annual physical examination performed in accordance with the order of the Ministry of Public Health of the Russian Federation. People over age 60, who at the moment of examination were in satisfactory health condition, were included into the study. People in which OAB had been detected or who used to take antimuscarinic were excluded from the study. Assessment tools for examining the patients' lower urinary tract condition were as follows: OAB-q SF, urination diaries, and uroflowmetry.

In the course of the experiment conducted, we found that 1/3 of people, both men and women greater than 60 years of age, who did not previously seek medical advice due to urination troubles, had symptoms of detrusor overactivity. These symptoms were moderate and did not bother patients too much in most cases (63.4%). It was also found that most patients consumed no more than 300mg caffeine with beverages per day, with 30% and 10% of patients suffering from OAB or severe detrusor overactivity, respectively. At the same time, almost 50% of patients taking more than 300 mg of caffeine per day suffer from OAB.

48.1% of people over 60 years of age suffering from overactive detrusor symptoms consume greater than 300 mg caffeine daily, which is significantly higher than that of their peers who do not intake excessive amounts of caffeine.
