The epidemiology of XXXX . A survey in western Jerusalem.

@entity1 @entity28 @entity1067 @entity547 @entity169
The epidemiology of @entity169 was investigated in a community survey in a neighbourhood of western Jerusalem in 1969-71. The current prevalence rate, excluding operated @entity547 , was 18 per 100 @entity1 aged 25 and over, and the lifetime prevalence, including operated @entity547 , was 24 per 100. Prevalence rose markedly with age; the lifetime prevalence rate reached 40 per 100 @entity1 at the ages of 65-74 and 47 per 100 at 75 and over. The prevalence of @entity547 was significantly higher in the presence of varicose veins, in @entity1 who reported symptoms of @entity1067 , and, among lean @entity1 only, in the presence of haemorrhoids. These associations may reflect the role of increased abdominal pressure. The prevalence of @entity547 was low in the presence of overweight or adiposity, suggesting that @entity28 is a protective factor. No significant age-independent associations were found with chronic cough, constipation, physical activity at work, or a number of other variables. Two-thirds of the @entity547 had not been operated upon. The prevalence of unrepaired @entity547 rose with age; 13% of all @entity1 aged 65-74 and 23% of those aged 75 and over had unoperated groin swellings. One in every five operated @entity547 showed evidence of recurrence. No significant age-independent associations were found between evidence of occurrence and other characteristics. A comparison of interview responses and examination findings showed that interview data on the presence of @entity547 were of low validity, mainly because of under-reporting.
