The main objective of the 2019 national public awareness campaign targeting the general public and healthcare professionals regarding BCPO was to raise awareness of this disease and its link to smoking, particularly among smokers and former smokers, so that they would discuss it with their doctors and to promote early diagnosis. A secondary objective was to encourage smokers to quit, as this preventive measure is the first line of treatment for this disease. The key findings from the pre-post evaluation study are as follows: The primary objective of the public awareness campaign was achieved, as awareness of COPD increased significantly among the surveyed population: 37% before the campaign versus 43% after its launch; Awareness after the campaign was higher among women (52%), in higher socioeconomic groups (52%), and among smokers and former smokers who currently smoke or have smoked more than 10 cigarettes per day (47%); However, the campaign had no impact on knowledge related to COPD (affected organs, symptoms, risk factors, affected populations), risk perception, or attitudes toward smoking cessation; In a future campaign, it would be useful to further refine the targeting and simplify the messages by distinguishing between 35- to 49-year-olds and lower socioeconomic groups to raise awareness of COPD, and between 50- to 64-year-olds and former smokers to promote screening.
