Impact Data - Mass Media Vasectomy Promotion Campaign
Impact evaluation of a 15-month mass media vasectomy promotion campaign in three major Brazilian cities: São Paulo, Fortaleza, and Salvador. The campaign consisted of a combination of prime-time television and radio spots, magazine ads, flyer distribution and an electronic billboard along with other public relations activities.
- PRO-VAS (Fortaleza): The mean number of calls and visits per month increased by 133% (from 15 to 35) during the campaign, while in the 6-months afterwards the monthly mean dropped to 12; less than before the campaign. The monthly mean number of vasectomies increased by 108% from 12 at pre-campaign, to 25 during the campaign, and then down to 7 for a total decline of 42%.(Note: the PRO-VAS clinic was disrupted by a labour dispute during the post-campaign period, which partially skewed the findings.)
- CEPARH (Salvador): The mean number of calls and visits per month increased by 169% (from 39 to 105), while in the 6-months afterwards the monthly mean fell to 85, for a total gain from pre-campaign of 118%. The monthly mean number of vasectomies increased by 59% from 32 at pre-campaign to 51 during the campaign, and then increased further during the post-campaign period to 59, for a total gain of 84%.
- PRO-PATER (São Paulo): The mean number of calls and visits per month increased by 261% (from 529 to 1,911 during the campaign), while in the 6-months afterwards the monthly mean fell back to 679, for a total gain from pre-campaign of 28%. The monthly mean number of vasectomies increased by 82%, (from 303 at pre-campaign to 550 during the campaign. The mean then dropped off slightly, to 542 for an overall increase of 79% during the post-campaign period.
