【 摘 要 】

Background

Oral health promotion can be achieved through education using various approaches including mass media health education campaigns. Mass media campaigns might increase oral health knowledge and perhaps could lead to desired behaviour changes and prevention of oral diseases. The aim of this study was to assess the effect of a national television campaign on knowledge of periodontal health among Iranian adults.

Methods

We conducted a population-based survey among adults aged 18–50 using a stratified multistage sampling method in the 22 districts of Tehran, Iran, in 2011. All participants were interviewed at two points in time: baseline (before launching the campaign) and follow-up assessment (after the campaign was finished) by using a validated instrument. The campaign included an animation clip about periodontal health and disease that was telecasted for ten days from several national TV channels. The instrument included items related to aetiology and sign of gum disease. Periodontal knowledge score and its change were calculated for each participant and were evaluated using statistical analyses in order to examine the effect of the campaign.

Results

In all 791 individuals (mean age: 32.6 years) were interviewed at baseline. Of these, 543 individuals were followed one month after the campaign. However, only 163 out of 543 reported that they had seen the campaign. Thus, comparison was made between those who had seen the campaign and who did not. The knowledge scores improved significantly among those who saw the campaign compared to those who did not (the mean knowledge score improvement 0.61 ± 0.96 versus 0.29 ± 0.8 respectively, p < 0.001). The results obtained from multiple logistic regression analysis indicated that improvement in periodontal knowledge was significantly associated with exposure to the campaign (OR = 2.20, 95% CI = 1.37-3.54), female gender (OR = 1.59, 95% CI = 1.05-2.43), being in age group 25–34 (OR = 1.76, 95% CI = 1.00-3.08), having higher education (high school: OR = 2.34, 95% CI = 1.23-4.43; university: OR = 3.33, 95% CI = 1.66-6.64), and baseline knowledge (OR = 0.25, 95% CI = 0.17-0.36).

Conclusion

The study demonstrated a significant impact of the mass media campaign on Iranian adults’ knowledge regarding periodontal health and disease.
