[Influence of knowledge relative to cancer on prevention behavior in the population of Bas-Rhin].
The tendency today is to make the population more aware of health in order to encourage their use of prevention activities. The aim of our telephone survey which was performed on a representative sample of the population (1,010) in the Bas-Rhin department in France, was to study the relationship between the level of knowledge of cancer and the use of screening techniques to prevent it. Eighty-two percent of the males and 78% of the females surveyed, show a profound understanding of cancer in general, the associated risk factors and its prevention. The level of awareness of males did not influence a specific behaviour (p = 0.68) towards cancer prevention. It was shown that in smokers, the more they smoke, the more they underestimate the chances of cure from all categories of cancer (p = 0.01). They both overestimate the number of cigarettes needed daily before smoking becomes toxic (p < 0.01) and are less active physically than nonsmokers (p < 0.007). Heavy smokers live in larger communities (p < 0.02) and smokers are younger than non-smokers (p < 0.0001). In the female population, the level of awareness did indeed influence their behaviour towards cancer prevention (p < 0.04). The level of knowledge was higher in both those who consciously attend cancer screening clinics (cervical Papanicolaou smears and faecal tests) and those who are opposed to faecal tests. Younger females are significantly less aware than those who are older (p = 0.0001) and more than two-thirds of these would not consider a cervical Papanicolaou smear as a preventative diagnostic tool. Females who conscientiously attend cancer screening clinics and who are very much aware of cancer, are generally older in age (p < 0.05). The occurrence of mammography as a preventative measure is both high and dependent on age. In conclusion, the level of knowledge of cancer cannot explain alone human behaviour towards the prevention of this disease. Other determinants responsible for influencing human behaviour towards cancer prevention will be better understood once the social sciences, epidemiology and anthropology units work together and combine resources to achieve a common goal.
