Knowledge about cancer screening programmes in Sardinia

High level of attendance by population is considered a proof of the efficacy in the screening programmes. Public health aims to increase people's attendance to cancer screening. The study aimed at assessing the level of knowledge and awareness about screening of citizens in Cagliari, from June to July 2016.

Recruitment took place near the atrium of the two main shopping centres of the city. The sample included 270 adults (138 men), 18-75 years old (mean age 46 years old). The information gathered from interviews were categorized by dichotomizing answers according to the knowledge and understanding of the discussed topics. Descriptive analysis was performed. The Chi-square test was used to assess gender and educational differences.

Results show that population's knowledge of screening is limited. Although the word "screening" is known, only half of the people who declared to have heard of this word know about the aim of screening. Colorectal cancer screening is the least known. Men and people with lower education are less informed than women and those with high education level.

In order to raise knowledge and awareness about cancer screening, special attention should be paid to communication and to the use of plain language. Future action should highlight the benefit of the screening procedure and thus contributing to spread the cancer prevention culture. Gender and socioeconomic inequalities must be taken into account when planning screening communication campaigns. General practitioner are highly trusted by people. They could play a decisive role to promote screening attendance.
