Adolescent usage of hormonal contraceptives and the risk of asthma
30 Jul 2023 • A study published in the Journal of Allergy and Clinical Immunology: In Practice found that initiation of hormonal contraception was associated with a 1.78 hazard ratio for developing new asthma. The study involved 184,046 girls and women aged 10 to 40 years, with 30,669 of them having received hormonal contraceptives and 153,377 not receiving such treatment. Girls who started hormonal contraceptive treatment before age 18 years had a higher risk of developing asthma compared to those who did not receive hormonal contraception. The most common types of hormonal contraception used were second-generation (83%) and third-generation oral pills (12%). After 3 years, the cumulative risk for initiating asthma treatment was 2.7% among patients treated with hormonal contraceptives and 1.5% among those who did not receive such treatment.
