Mater Mothers Hospital implementation of txt4two

The intervention group will receive the txt4two program. Txt4two is an evidence based program that incorporates mobile phone text-based messages, video messages and an information website following a goal setting appointment with a dietitian. Txt4two texts (messages, website and video links) will be sent automatically by text message. Certain text messages will be tailored based on the goals that women indicate in their goal-setting appointment. Some of these messages will also be interactive. Women will receive messages about the developmental stages of their fetus, diet and physical activity information and behaviour change encouragement, weight self-monitoring, weight reporting, and individual goal review. There will be a number of links also sent to videos that women may choose to watch (this will be sent within the content of some text messages). Participants will be able to indicate their preferred frequency of text messages. A maximum of 11 messages may be received in a week (this maximum is fewer in all but one week). This will occur for a maximum of 20 weeks. How long participants are involved in the program is dependent on what gestational age they are when they join the program. The txt4two text messaging program is not currently available to the public. This has previously been piloted. https://obgyn.onlinelibrary.wiley.com/doi/full/10.1111/1471-0528.14552 Dietetic goal setting appointments will be provided in three different modes - Telehealth (a skype-type call with a dietitian), Face to Face (one on one with a dietitian), or in a dietitian-led workshop setting with other expectant mothers. Both the group and face to face appointment are held in the usual location of dietetic care in the hospital’s antenatal clinic. The telehealth appointment will be ‘hosted’ in the same room, but via a skype-like platform endorsed for use in the clinical setting. Women may be at home during this call. The current website is www.matermothers.org.au/diet and this will be populated with more nutrition in pregnancy related information, including the videos that will be re-recorded for this site. . The nutrition content will be based on the recommendations of the Australian Dietary Guidelines for pregnancy with emphasis on replacement of sugar sweetened beverages, increased fruit and vegetable intake, reduction of discretionary food groups and consumption of regular meals.
