- Description
- Background: Elevated blood glucose levels in pregnancy increases the risk of adverse pregnancy outcomes. Modifying consumption of carbohydrate‐rich foods is important for blood glucose regulation; however, the tools commonly used to assist in guiding portion control are impractical. The present study aimed to evaluate usability of ServAR preg, a mobile phone‐based nutrition tool, and its effectiveness with respect to improving carbohydrate and standard serve size knowledge in pregnant women. Methods: A baseline survey assessed knowledge of carbohydrates and standard serve sizes of pregnant women. A subset of women living in Newcastle were invited to use ServAR preg, containing pregnancy nutrition information and augmented reality guidance on portion control. A follow‐up survey was sent to all women 4 weeks after baseline and women who received ServAR preg also received a process evaluation survey after 10 weeks. Results: Responses were received from 186 pregnant women for the baseline survey, with 97 completing the follow‐up (52.2%). Of the 56 women eligible to receive ServAR preg in the sub‐study, 47 accepted (83.9%) and, of these, 40 completed the process evaluation survey (85.1%). At follow‐up, there was a significant group × time interaction in favour of the ServAR preg group for carbohydrate quantification knowledge (F1,279 = 9.705, P = 0.002). Standard serve size knowledge did not change between groups. In the process evaluation survey, 80% strongly agreed/agreed that ServAR preg made them more aware of how much they ate and 72.5% found ServAR preg easy to use. Conclusions: ServAR preg has shown potential to educate pregnant women about carbohydrate quantification and increase portion size awareness. Further refinement of the tool and evaluation is needed to improve standard serve size knowledge.
