Effect of Telehealth on Promoting a Healthy Lifestyle and Weight Control Among Pregnant Women

Excessive weight gain during pregnancy is recognized as a global epidemic and is associated with complications, such as gestational diabetes. While a healthy diet and regular physical activity positively influence weight control and overall well-being, in-person consultations can be costly and time-consuming. The use of digital technologies, particularly smartphones, has increased for delivering lifestyle interventions and improving well-being. These technologies provide affordable access to health services for pregnant women, especially those in remote areas. This narrative review was conducted to evaluate the effect of telehealth on weight control and the promotion of a healthy lifestyle among pregnant women. A search was performed in the PubMed, Google Scholar, and Scopus databases. Of the 631 initial articles published during 2020-2024, 15 were selected and evaluated after excluding irrelevant articles, review articles, and those without full texts. The selected articles showed that mobile health (mHealth) could improve indicators, such as weight, body mass index (BMI), maternal and infant health, and lifestyle. However, certain limitations, including access issues, cultural barriers, and fluctuations in service quality, impacted their effectiveness. Based on the findings of these articles, it is suggested that personalized interventions be designed with continuous consultations and daily reminders. Forming virtual groups and providing timely feedback can strengthen the sense of belonging and promote adherence. These strategies are valuable for telehealth clinics and online counseling programs.
