Brief summary

Up to 50% of women gain more than the recommended amount of weight during pregnancy. Retention of weight gained during pregnancy contributes to becoming overweight and obese and subsequent chronic disease risk, with the associated personal, financial and public health burdens. This study is a randomised-controlled trial to evaluate a consumer co-created text-message-based intervention to support women to improve diet quality and decrease postpartum weight retention.

Interventions

This randomised controlled trial is an evaluation of an intervention that is being designed/evaluated to target retention of excess weight retention post pregnancy, specifically targeting areas of diet, exercise and breastfeeding. A total of 80 women will be recruited to this trial and will be randomised to two study groups: mater4newmums program (treatment), or standard care (control). The mater4newmums program will be delivered by an automated text messaging system (Propelo, http://propelo.c

This randomised controlled trial is an evaluation of an intervention that is being designed/evaluated to target retention of excess weight retention post pregnancy, specifically targeting areas of diet, exercise and breastfeeding. A total of 80 women will be recruited to this trial and will be randomised to two study groups: mater4newmums program (treatment), or standard care (control). The mater4newmums program will be delivered by an automated text messaging system (Propelo, http://propelo.com.au/), designed to send individually tailored text messages which are interactive. Text message content will include links to short motivational video messages from experts in the health profession, customised texting alert system, weekly/fortnightly (as decided by participant) weight and goal self monitoring texts (interactive- participants can text back), and links to a website with detailed healthy eating and physical activity information. These messages will be received intensively over a 6 month period following the birth of their baby, plus tapered monthly texts to 12 months. This intervention/program is being developed by the principal investigator (Associate professor and dietitian) with input from other allied health staff at Mater Misericordiae Limited. Participants will be given the option to tailor the frequency of the text messages, and the goals (e.g. weight loss, eating more vegetables) and rewards (e.g. bubble bath) referred to in the text messages. The messages will also be tailored to refer to the participant and the investigator of the study by name. This program is content and text message delivery schedules of different text message types is presently under development in consultation with mothers from the hospital, thus the maximum and minimum text messages received is not yet defined. Participants randomised to the intervention group will receive this in addition to standard clinical care (30 minute goal setting and counselling session at 34-36 weeks pregnancy), Mater Mothers Hospital 'nutrition for new mums' handout', direction to access 'nutrition for new mums' 8 minute video (matermothers.org.au) and additional dietetic resources as requested. Standard clinical care aspects of the intervention will be delivered by dietitians at the Mater Mothers Hospital, while mater4newmums program specific components will be delivered solely by text message. Engagement with the study text messages, and linked resources is measured and analysed.
