To describe the variation in the incidence of colorectal cancer across Northern Ireland and relate it to factors associated with community deprivation.
This was a cross sectional descriptive study.
Incidence data were obtained from a population based register for the period 1990-91.
Small areas were characterised by their « affluence », or lack of it, by deriving a Townsend deprivation score for each electoral ward, using information from the 1991 census.
Participants, main outcome measures, and statistical methods - The age standardised incidence was calculated for all colorectal cancer cases diagnosed histologically in 1990-91.
Electoral wards were grouped into quintiles of the population after ranking of their Townsend scores and the association with incidence was studied using Poisson regression.
The age standardised colorectal cancer incidence ranged from 22.5 (for quintile 1) to 29.9/100 000 (quintile 5) for men but the trend for women was less regular and rates were 18.4,23.8,27.3,26.5, and 23.9/100 000 for quintiles 1-5 respectively (that is, from the most « affluent » to the most « deprived » fifths of the population).
After adjusting for age and sex in Poisson regression, there was a significant association between the total colorectal cancer incidence and levels of community deprivation.
The rate ratio for the most deprived quintile of the population (compared with the least) was 1.28 (95% CI 1.06,1.53). (...)
