Background
We aimed to determine the prevalence of consumption of oral contraceptives (OCs) among adolescents and young women living in Spain and to identify the factors associated with this consumption.
Methods
We performed a cross-sectional study on the consumption of OCs by women aged 15–30 years residing in Spain. We used secondary individualized data from the 2006 (n = 2513) and 2012 (n = 1530) Spanish National Health Surveys. The dependent variable was the use of OCs in the previous 2 weeks. Independent variables included sociodemographic characteristics, comorbidity, lifestyle, and healthcare resource utilization.
The prevalence of OC consumption was analysed by investigating the changes observed between 2006 and 2012. We used multivariate logistic regression to identify the independent factors associated with OC use in each year.
Results
In 2006, 14.42 % of women reported using OCs; this percentage dropped to 10.21 % in 2012 (p < 0.05). Multivariate analysis revealed an association between OC use and visits to the gynaecologist (AOR, 5.60 [95 % CI, 2.93–10.73] in 2006; and AOR, 3.55 [95 % CI, 1.30–9.73] in 2012), Pap smear tests (AOR, 1.8 [95 % CI, 1.23–2.87] in 2006; and AOR, 2.42 [95 % CI, 1.30–4.51] in 2012), and smoking in 2006 (AOR, 1.42 [95 % CI, 1.04–1.93]).
Conclusions
There was a significant decrease in OC use from 2006 to 2012 among adolescents and young women living in Spain. In the present study, consumers of OCs were women who visited a gynaecologist more often and complied more with preventive measures such as Pap smear testing. Also, women who reported having used OCs were more likely to smoke than the rest of the study population, although the smoking habit is a risk factor for thrombotic events in women who take OCs.
