目前,医疗类app不断涌现。2017年9月,发表在《Eur J Prev Cardiol.》的一项6周、双组、平行、随机对照试验调查了一种创新的app为心血管疾病患者提供低盐食物选择支持的有效性。

背景:SaltSwitch是一种创新的智能手机应用程序(app),可使购买者扫描包装食品的条形码,并在手机屏幕上接收到即时的、有说明的交通灯似的营养标签,同时还会收到低盐替代物的建议。该研究目的为确定SaltSwitch为心血管疾病患者提供低盐食物选择支持的有效性。

设计:新西兰奥克兰进行的6周、双组、平行、随机对照试验(基线2周,干预4周)。

方法:66名确诊为心血管疾病的患者(平均(SD)64(7)岁)按照1:1的比例随机分配到SaltSwitch智能手机app或对照组(常规治疗)中。首要结局指标为4周干预期间购买的家庭包装食品的盐含量(g/MJ)。次要结局指标为饱和脂肪含量(g/MJ)、能量含量(KJ/kg)和家庭购买食物的支出(NZ$);收缩压(mmHg)、尿钠(mg)、SaltSwitch app的使用和可接受度。

结果:33名心血管疾病参与者分配到SaltSwitch干预组,33名分配到对照组。4周的干预期,家庭盐的购买出现显着降低(平均差(95% CI),-0.30(-0.58~-0.03)g/MJ),相当于每天每人减盐约0.7g。次要结局指标无显着的组间差异(P>0.05)。

结论:SaltSwitch智能手机app在帮助心血管疾病患者购买低盐食物上是有效的。需要具有更长随访期的更大型试验来确定SaltSwitch智能手机app对血压的影响。
