Global unmet need for contraception remains high. Contraceptive health-related beliefs are a barrier to contraceptive use but are poorly understood. This study examined quantitative differences in two health-related beliefs between pills, injectables, and implants.
We used cross-sectional baseline data collected between August and December 2016 from Nairobi (urban) and Homa Bay (rural) Kenya among women aged 15 to 39 years (N = 5081). Dichotomous outcome variables were constructed for two health-related beliefs (infertility and serious health problems) for the three methods. Using a socioecological framework, possible risk factors at individual, relationship, and community levels were identified a priori. We used logistic regression to identify factors associated with method-specific beliefs.
Roughly a quarter of participants believed the methods caused serious health problems, while a smaller overall proportion believed the methods caused infertility. Risk factors patterned similarly across methods but differed between beliefs. In adjusted models, perceived partner approval of a method was associated with lower odds of believing it caused infertility or serious health problems. Unsatisfactory or mixed social network experiences predicted serious health problems but not infertility beliefs. Current use was associated with lower odds of believing all three methods caused serious health problems, but only implant users were more likely to believe they caused infertility. Past use was associated with higher odds of serious health problems but not infertility beliefs.
Across three methods, negative community and perceived partner attitudes toward specific contraceptive methods were associated with higher individual-level odds of contraceptive health beliefs in Kenya.
Efforts to support women who want to use contraception should focus on providing information on contraceptive health and fertility concerns, ideally targeting partners and women of all ages in addition to potential contraceptive users. It is reasonable to address these concerns broadly across commonly used contraceptive methods.
全球避孕需求未得到满足的情况仍然很高。与避孕相关的健康信念是避孕使用的障碍,但人们对此了解甚少。本研究比较了三种避孕方法(避孕药、注射剂和植入剂)在两种健康相关信念上的差异。
我们使用 2016 年 8 月至 12 月期间在肯尼亚内罗毕(城市)和霍马湾(农村)收集的 15 至 39 岁女性的横断面基线数据(N=5081)。为三种方法构建了两个健康相关信念(不孕和严重健康问题)的二分变量。根据社会生态学框架,预先确定了个体、关系和社区层面的可能风险因素。我们使用逻辑回归来确定与方法特异性信念相关的因素。
大约四分之一的参与者认为这些方法会导致严重的健康问题,而总体上较小的比例认为这些方法会导致不孕。风险因素在不同方法之间呈现相似模式,但在信念方面存在差异。在调整后的模型中,感知伴侣对方法的认可与较低的认为该方法导致不孕或严重健康问题的可能性相关。不满意或混合的社交网络经历预测严重的健康问题,但不预测不孕信念。当前使用与较低的认为所有三种方法都会导致严重健康问题的可能性相关,但只有植入剂使用者更有可能认为它们会导致不孕。过去的使用与较高的严重健康问题的可能性相关,但不孕信念则不然。
在三种方法中,对特定避孕方法的负面社区和感知伴侣态度与肯尼亚女性对避孕健康信念的个体水平较高相关。
支持希望使用避孕方法的女性的努力应侧重于提供关于避孕健康和生育问题的信息,理想情况下应针对伴侣和所有年龄段的女性,以及潜在的避孕使用者。在广泛使用的避孕方法中,合理地解决这些问题。
