Can a public health package on glaucoma reach its target population?
OBJECTIVE
A pilot study to assess how successful a newspaper advertisement and a radio interview about glaucoma are at reaching their target population.


METHODS
The health intervention comprised two components: an interview on local radio and an advertisement in the local paper. Our target population were residents aged 45 years and above in either Southall (West London) or the Isle of Wight (IOW). A questionnaire was developed to be carried out pre- and post-intervention. The data from both locations pre and post were coded and cleaned. Tests of significance were carried out to assess statistical significance for differences in proportion, with tests for trend used where appropriate. All statistical analyses were carried out using Stata7.


RESULTS
Overall, the proportion who had heard of glaucoma increased from 54% before the intervention to 60% after (chi(2) = 3.7, P = 0.055). The proportion who had heard of the disease increased by 13% (chi(2) = 8.76, P = 0.003) in Southall and by 8% (chi(2) = 5.02, P = 0.025) on the IOW. The proportion reporting seeing the advert increased significantly in both areas with greater effect in Southall. Those reporting hearing the radio interview only increased in Southall. On the IOW, females were more knowledgeable and responded more positively to the intervention. This differed in Southall where males tended to be the positive responders. Conclusion In both areas a significant effect on those having heard of glaucoma was found. This could be attributed to both the advert and interview in Southall but would appear to be attributable to the newspaper advertisement alone on the IOW.
