ABSTRACT Objective: To analyze the factors associated with the individual use of insect repellent by women of childbearing age living in area endemic for arboviruses in Fortaleza, Brazil. Methods: This is a cohort study carried out between 2018 and 2019 with women aged between 15 and 39 years in Fortaleza, state of Ceará, Brazil. A total of 1,173 women users of one of the four selected primary health care units participated in the study. The outcome was divided into: continued use, discontinued use, and nonuse of insect repellent. Crude and adjusted multinominal logistic regression analysis was carried out guided by a hierarchical model, with presentation of the respective odds ratio (OR) and 95% confidence intervals (95%CI). The independent variables include: socioeconomic and demographic data, environmental and sanitary characteristics, knowledge of the insect repellent, and behavioral and pregnancy-related aspects. Results: Only 28% of the participants reported using insect repellent during the two waves of the cohort. Women with higher education (OR=2.55; 95%CI 1.44–4.51); who are employed (OR=1.51; 95%CI 1.12–2.03); who received guidance from healthcare professionals (OR=1.74; 95%CI 1.28–2.36) and the media (OR=1.43; 95%CI 1.01–2.02); who intensified precautions against mosquitoes during the epidemic (OR=3.64; 95%CI 2.29–5.78); and who were pregnant between 2016 and 2019 (OR=2.80; 95%CI 1.83–4.30) had increased odds for continued use of insect repellent. Conclusion: The use of insect repellent among women of childbearing age was associated with a higher level of education, employment, guidance on insect repellent provided by healthcare professionals and the media, behavioral changes to protect against mosquitoes during the Zika virus epidemic, and pregnancy when occurring as of the beginning of the epidemic period.

RESUMO Objetivo: Analisar os fatores associados ao uso de repelente individual por mulheres em idade fértil residentes em área endêmicas para arboviroses em Fortaleza, Brasil. Métodos: Coorte realizada entre 2018 e 2019, com mulheres entre 15 e 39 anos, moradoras em Fortaleza, Ceará, Brasil. Participaram 1.173 mulheres, usuárias de quatro unidades primárias de saúde do município. O desfecho foi categorizado em: uso continuado, uso descontinuado e não uso de repelente. Realizada análise de regressão logística multinominal norteada por modelo hierárquico, com apresentação dos respectivos odds ratio (OR) e intervalos de confiança de 95% (IC95%). As variáveis independentes incluem: dados socioeconômicos e demográficos, características ambientais e sanitárias, conhecimento sobre o repelente e aspectos comportamentais e relacionados à gravidez. Resultados: Somente 28% das participantes referiram o uso de repelente durante as duas ondas da coorte. Mulheres com escolaridade superior (OR=2,55; IC95% 1,44–4,51); com emprego (OR=1,51; IC95% 1,12–2,03); que receberam orientações por profissionais da saúde (OR=1,74; IC95% 1,28–2,36) e pela mídia (OR=1,43; IC95% 1,01–2,02); que intensificaram os cuidados contra o mosquito na epidemia (OR=3,64; IC95% 2,29–5,78); estavam grávidas entre 2016 e 2019 (OR=2,80; IC95% 1,83–4,30) tiveram as chances aumentadas para uso continuado de repelente. Conclusões: O uso de repelente entre mulheres em idade fértil mostrou-se associado a um maior nível de escolaridade, ao emprego, às orientações sobre repelente fornecidas por profissionais de saúde e pela mídia, às mudanças comportamentais de cuidado contra o mosquito durante a epidemia da Zika e à gravidez quando ocorrida a partir do início do período epidêmico.
