Sources of information and knowledge about health and nutrition: can viewing one television programme make a difference?

Abstract

This three-stage national longitudinal survey of 300 respondents evaluated the impact on levels of nutrition knowledge of a specially designed television programme. These levels were assessed among subgroups using different sources of health information. The study was fielded before programme viewing, within three days of programme viewing and about six months after programme viewing. Up to five sources per respondent were obtained. Health information sources analysed included magazines, television, newspapers and doctor/clinic/hospital. Results showed that knowledge levels consistently increased among all groups after programme viewing and also across time ( p<0.001). In general, media users showed higher levels of knowledge than their non-user counterparts; however, only magazine users showed higher and significant differences in knowledge. Programme viewing led to an increased selection of television and newspapers as sources of health information. Magazine use and the use of doctors as health information sources remained the same after programme viewing.
