This study examined demographic, sexual history and weekly contextual variables, and perceptions about microbicides as predictors of microbicide-like product use.
Adolescent girls (N = 208; 14-21 years) participated in a 6-month study in which they completed three face-to-face interviews and 24-weekly phone call interviews. Participants were given microbicide-like products (vaginal lubricants) and encouraged to use them with condoms when they had intercourse.
Of the girls, 75% had had a sexual opportunity to use the product. Using multi-variable logistic regression, the following variables independently predicted ever using the product: length of sexual experience, number of lifetime vaginal partners, and the Comparison to Condoms subscale on the Perceptions of Microbicides Scale. Using a mixed model repeated measure linear regression, the following variables independently predicted frequency of use: week of the study, age, condom frequency prior to the study, and three subscales on the Perceptions of Microbicide Scale: namely, the Comparison to Condoms subscale, the Negative Effects subscale, and the Pleasure subscale.
Most girls used the product, including those who were not protecting themselves with condoms. Girls' initial perceptions regarding the product predicted initial use and frequency of use. Further research should evaluate the best methods for supporting the use of these products by young or sexually less experienced girls.
本研究调查了人口统计学、性史和每周情境变量，以及对杀微生物剂的认知作为杀微生物剂类产品使用的预测因素。
青春期女孩（N = 208；14 - 21岁）参与了一项为期6个月的研究，在此期间她们完成了三次面对面访谈和24次每周电话访谈。参与者被给予杀微生物剂类产品（阴道润滑剂），并被鼓励在性交时与避孕套一起使用。
在这些女孩中，75%有过使用该产品的性机会。通过多变量逻辑回归分析，以下变量独立预测了曾经使用过该产品：性经历时长、终身阴道性伴侣数量，以及杀微生物剂认知量表上的“与避孕套比较”子量表。通过混合模型重复测量线性回归分析，以下变量独立预测了使用频率：研究周数、年龄、研究前使用避孕套的频率，以及杀微生物剂认知量表上的三个子量表：即“与避孕套比较”子量表、“负面影响”子量表和“愉悦感”子量表。
大多数女孩使用了该产品，包括那些未使用避孕套进行自我保护的女孩。女孩对该产品的初始认知预测了初始使用情况和使用频率。进一步的研究应评估支持年轻或性经验较少的女孩使用这些产品的最佳方法。
