Abstract

Background: We conducted a single-centered randomized controlled single-blinded trial (i.e. trained interviewers; blinded to group allocation). The target population included adolescent girls in the Kumbo West Health District (KWHD) of Cameroon. This trial tested the efficacy of weekly educational one-way text messages to improve perception of adolescent girls on sexo-reproductive health.

Methods: Allocation concealment (1:1) was determined by sequentially numbered sealed opaque envelopes. A total of 398 participants either received the mobile phone sexo-reproductive health text messages (199) or not (199). A blinded program secretary send out text messages and recorded delivery. Data was collected and managed at baseline and at 6 month intervals using an interviewer-administered questionnaire before and after intervention, then analysed using the independent T-test (mean differences) and ANOVA on SPSS version 21.

Results: The mean knowledge, attitude and practice scores respectively increased significantly from 6.03, 4.01 and 3.45 at baseline to 7.99, 5.83 and 4.99 at the end of the study. After performing ANOVA for the overall correct knowledge, positive attitudes and good practices respectively for between and within the intervention groups, we obtained: (F = 15.12, P = 0.023), (F = 60.21, P = 0.001) and (F = 57., P = 0.013) which showed statistical significance thus indicating the overall improvement in adolescents girls perception as a result of the intervention and not by chance. Majority (65.3%) of the participants were satisfied with the Short Message Service (SMS).

Conclusion: This trial has contributed to the body of knowledge and evidence on the use of mobile phone technology using educative SMS to improve adolescent girl's perception on sexo-reproductive health in Cameroon.

一项关于手机短信改善喀麦隆少女性健康与生殖健康的随机对照试验。

背景:我们进行了一项单中心随机对照单盲试验(即训练有素的采访者;对分组分配不知情)。目标人群包括喀麦隆昆博西卫生区(KWHD)的少女。这项试验测试了每周单向教育短信的有效性，以提高青春期女孩对性健康和生殖健康的认识。方法:采用按顺序编号的密封不透明信封进行分配隐蔽(1:1)。共有398名参与者收到或没有收到手机性健康与生殖健康短信(199条)。一名失明的节目秘书发送短信并录下讲话内容。在干预前后使用访谈者填写的问卷，在基线和6个月的间隔收集和管理数据，然后使用SPSS 21版的独立t检验(平均差异)和方差分析进行分析。结果:知识、态度、实践平均分分别由研究开始时的6.03、4.01、3.45分显著提高至研究结束时的7.99、5.83、4.99分。在对干预组之间和干预组内的总体正确知识、积极态度和良好行为分别进行方差分析后，我们得到:(F = 15.12, P = 0.023)、(F = 60.21, P = 0.001)和(F = 57)。， P = 0.013)，具有统计学意义，这表明青少年女孩认知的整体改善是干预的结果，而不是偶然的。大多数(65.3%)的参与者对短信服务(SMS)感到满意。结论:这一试验为利用手机技术、利用教育短信提高喀麦隆少女对性健康和生殖健康的认识提供了大量知识和证据。试验注册:泛非临床试验注册中心，PACTR201805003259293。2018年3月28日注册
