A review of pregnancy iPhone apps assessing their quality inclusion of behaviour change techniques and nutrition information

摘要

Smartphone apps for use in pregnancy are common and could influence lifestyle behaviours, but they have not been evaluated. This review aimed to assess the quality of iPhone pregnancy apps and whether they included behaviour change techniques (BCTs) and/or pregnancy‐specific nutrition information. A keyword search of the Australian iTunes app store was conducted. For inclusion, apps had to be available at no cost, in English, intended for use by pregnant women, and contain nutrition information. App quality was assessed using the Mobile Application Rating Scale (MARS). Absence or presence of BCTs was assessed using the CALO‐RE taxonomy, with type of nutrition information included also reported. The initial key word search identified 607 apps, with 51 iPhone apps included in final evaluation. Mean overall MARS quality rating score was 3.05 out of 5 (1 = inadequate; 5 = excellent). The functionality subscale scored highest (mean = 3.32), and aesthetics scored lowest (mean = 2.87). Out of a possible 40 BCTs, 11 were present across the apps with a median of three BCTs (range: 0–6) identified per app. The median number of pregnancy‐specific nutrition topics per app was three (range 0 to 7). Despite the availability of a large number of iPhone pregnancy apps, few are of high quality, with only a small number of BCTs used and limited inclusion of pregnancy‐specific nutrition information. It is important to be aware of limitations within current pregnancy apps before recommending usage during this key life stage.
