females aged 40–75 years with a Health Insurance Plan
Prospective RCT. Randomized to two subgroups receiving SMS mobile phone texts: (1) to do a mammogram or (2) containing information about mammogram screening.
SMS tests either inviting women to do a mammogram or containing information about mammograms.
31% from group 1 and 32% from group 2 did a mammogram during the 6 months after intervention.
12-week RCT. Participants were asked to record their waist circumference and body weight, diet, and exercise levels using a weekly diary through the internet or by cellular phone.
Participants received weekly SMS/internet reminders about diet and exercise.
Systolic and diastolic blood pressure decreased by 6.5 and 4.6 mmHg in the intervention group. No significant changes were observed in the control group. Total cholesterol also reduced by 12.9 mg/dL in the intervention group but increased by 1.5 mg/dL in the control group.
6-week RCT. Randomized to an intervention group that received text messages to enhance knowledge, attitudes, and practice concerning iron deficiency and iodized salt consumption.
The intervention group received daily text messages over 6 weeks. Urinary iodine concentration was measured at baseline and 8 weeks to see if there were any improvements.
Knowledge significantly improved by the end of the study () but urinary iodine levels did not increased.
RCT. Underserved pregnant women and new mothers were randomized to receive text messages to change their health, health beliefs, practices and behaviors to improve clinical outcomes, or to continue with usual health care.
Text4baby delivers text messages (https://text4baby.org/) to pregnant women and new mothers targeting underserved women facing health disparities.
There was an improvement of attitudes toward alcohol consumption from baseline to followup ().
6-month RCT. Randomized to a smartphone application or a website or paper diary weight loss intervention.
The app was used to self-monitor diet and activity and feedback was provided via weekly message.
Body mass index reductions after 6 months were the highest amongst the app users (−1.6 kg/m2), followed by the diary group (−1.0 kg/m2) and the website group (−0.5 kg/m2), indicating that this app was acceptable and feasible.
12-week RCT. Participants were asked to record their waist circumference and body weight, diet, and exercise levels using a weekly diary through the internet or by cellular phone.
Participants received weekly SMS/internet reminders about diet and exercise.
Waist circumference and body weight significantly decreased by 3.0 cm and 2.0 kg at 12 weeks compared with baseline. Increases were found in the control group.
12-month RCT. Randomized to receive daily interactive and personally weight-relevant text messages or monthly e-newsletters.
Daily weight-relevant SMS and MMS received 4 times/day over 12 months.
Participants with greater adherence lost more weight 6 () and 12 months () than loss who were less adherent. Text messaging could be a useful adjunct to weight loss treatments.
