To determine the effectiveness of implementation of a prevention programme via mobile phone text messaging in enhancing knowledge, attitudes and practice concerning iodine deficiency and iodized salt consumption.
In a randomized controlled trial, participants were subjected to a brief tele-educational support regarding iodine deficiency and the importance of iodized salt consumption. The intervention group received daily text messages via mobile phone for 6 weeks. Knowledge, attitude and practice scores, urinary iodine concentration and salt iodine content were assessed at baseline and 8 weeks after the intervention.
Participants were recruited from health-care centres in Tehran, the capital city of Iran.
For the present study 205 females aged ≥18 years were randomly assigned to the intervention (n 95) and control (n 110) groups.
A significant difference was found in median knowledge scores between the intervention and control groups at follow-up (P = 0.004). There was also a significant difference in median attitude scores between the intervention and control groups (P = 0.02). The intervention group did not differ significantly in median practice score, urinary iodine concentration and salt iodine content from the control group.
Text messaging interventions are effective in improving individuals' knowledge and attitudes regarding preventive health-care topics.
通过手机短信来确定预防碘缺乏症和碘盐消费的方案实施在增强知识、态度和实践方面的效果。
在一项随机对照试验中，参与者接受了有关碘缺乏症和碘盐消费重要性的简短远程教育支持。干预组在 6 周内每天通过手机接收短信。在干预前和干预 8 周后评估知识、态度和实践得分、尿碘浓度和盐碘含量。
参与者是从伊朗首都德黑兰的医疗中心招募的。
本研究共纳入了 205 名年龄≥18 岁的女性，随机分为干预组（n=95）和对照组（n=110）。
干预组和对照组在随访时的中位数知识得分有显著差异（P=0.004）。干预组和对照组在中位数态度得分上也有显著差异（P=0.02）。干预组的实践得分、尿碘浓度和盐碘含量与对照组相比没有显著差异。
短信干预在改善个人对预防保健主题的知识和态度方面是有效的。
