Willingness to pay for short- and long-acting contraceptives among female adolescents and their parents in Brazil:a pilot study

ABSTRACT Objective To evaluate willingness to pay for short- and long-acting reversible contraceptive methods among female Brazilian adolescents and their parents, as well as their perspective on using such methods. Methods This is a cross-sectional study of female adolescents aged 13 to 19 years and their parents. We surveyed to estimate their willingness to pay for contraceptive methods. The values are expressed as mean±standard deviation in Brazilian reals (R$). Spearman correlation was employed for socioeconomic status of parents, age of adolescents and their standpoints. The methods types and adolescent and parent perspectives were analyzed by the test χ2. To determine an agreement between pairs and their willingness to pay, we used the Bland-Altman plot. Results A total of 165 surveys were collected. Short-acting method was significantly more acceptable to pay than the long-action method, by both parents and their daughters. Parents and their daughters are willing to pay out-of-pocket R$ 52,25±22,48 and R$ 51,63±21,24 for short-acting reversible contraception method, and R$ 176,83±130,34 and R$ 174,83±143,64, for long-acting method, respectively. Bland-Altman analysis indicated an agreement on both perspectives and the price they are willing to pay for each contraceptive method. Conclusion Parents and adolescent daughters are more willing to pay for short-acting methods. We showed an agreement between the parent and the daughter for the values paid for each method.

摘要 目的：评估巴西13~19岁女性青少年及其父母对短效、长效可逆避孕方法（short- and long-acting reversible contraceptive methods的支付意愿，以及他们对使用此类方法的看法。
方法：本研究为横断面研究，研究对象为巴西13~19岁女性青少年及其父母。通过问卷调查评估其对避孕方法的支付意愿。数据以巴西雷亚尔（R$）的均值±标准差表示。采用斯皮尔曼相关分析（Spearman correlation）分析父母社会经济地位、青少年年龄与其观点的相关性；采用卡方检验（chi-square test）分析避孕方法类型及青少年、父母的观点差异；使用布兰德-奥特曼图（Bland-Altman plot）评估配对对象间的支付意愿一致性。
结果：共回收有效问卷165份。父母与女儿均认为短效避孕方法的支付意愿显著高于长效方法。父母与青少年女性对短效可逆避孕方法的自付支付意愿分别为52.25±22.48雷亚尔与51.63±21.24雷亚尔，对长效可逆避孕方法的自付支付意愿分别为176.83±130.34雷亚尔与174.83±143.64雷亚尔。布兰德-奥特曼分析显示，二者对各类避孕方法的支付意愿及观点均具有一致性。
结论：父母与青少年女儿对短效可逆避孕方法的支付意愿更高。本研究证实，父母与女儿在各类避孕方法的支付金额上具有一致性。
