The oral contraceptive pill is the most widely used method of contraception and when adhered to perfectly is 99% effective at preventing pregnancy. However, adherence to the pill is relatively low. Knowledge has shown to be important in continuation of the pill, and previous research shows the importance of health literacy in adhering to medication in chronic illnesses, but its role has yet to be explored in this behavior.
This cross-sectional study examined the associations between health literacy, knowledge of the pill and adherence, as well as the predictive ability of these two variables and their interaction, in predicting adherence. Recruited through CloudResearch, 193 women ( = 32.63 years, = 5.98) residing in the United States completed the Health Literacy Skills Instrument - Short Form, a previously validated measure of oral contraceptive pill knowledge and the Medication Adherence Report Scale.
Results showed a strong positive correlation between health literacy and adherence ( = .76) and moderate associations between health literacy and knowledge ( = .42), and knowledge and adherence ( = .42). The final model of the hierarchical multiple regression accounted for 59.8% of variance in adherence, with health literacy ( = .69) and length of time taking the pill ( = .13) the only significant predictors of adherence.
Family planning clinics should consider assessing the patient's health literacy skills before prescribing the pill to ensure patients fully understand the requirements.
口服避孕药是使用最广泛的避孕方法,若能完美坚持服用,其预防怀孕的有效率为99%。然而,避孕药的服药依从性相对较低。已有研究表明知识对于持续服用避孕药很重要,并且先前的研究显示健康素养在慢性病患者坚持服药方面具有重要性,但在这种行为中其作用尚待探索。
这项横断面研究考察了健康素养、避孕药知识与服药依从性之间的关联,以及这两个变量及其相互作用在预测服药依从性方面的预测能力。通过CloudResearch招募了193名居住在美国的女性(年龄 = 32.63岁,标准差 = 5.98),她们完成了《健康素养技能量表简版》、一种先前已验证的口服避孕药知识测量工具以及《药物依从性报告量表》。
结果显示健康素养与服药依从性之间存在强正相关(相关系数 = 0.76),健康素养与知识之间存在中度关联(相关系数 = 0.42),知识与服药依从性之间也存在中度关联(相关系数 = 0.42)。分层多元回归的最终模型解释了服药依从性方差的59.8%,其中健康素养(相关系数 = 0.69)和服药时长(相关系数 = 0.13)是服药依从性的仅有的显著预测因素。
计划生育诊所应考虑在开避孕药之前评估患者的健康素养技能,以确保患者充分理解相关要求。
