Lifestyle Intervention for Pregnancy Weight Gain
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a mobile health intervention to help pregnant women who are overweight or obese manage weight gain during pregnancy. The intervention, called a Lifestyle Intervention, includes a mobile app, personalized text messages, and phone coaching sessions with a dietician. It aims to help participants maintain healthy weight gain as recommended by health guidelines, with additional support if needed. Ideal candidates for this trial are pregnant women with a body mass index (BMI) between 25 and 39 who have access to a smartphone. Researchers will compare participants to those receiving usual medical care to determine which approach is more effective. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance pregnancy health management.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your healthcare provider.
What prior data suggests that this mHealth intervention is safe for pregnant women?
Research shows that lifestyle changes during pregnancy, like those in this study, are generally easy for participants to manage. Previous studies have found that these changes help women gain a healthy amount of weight during pregnancy, with no major reports of harm or serious side effects.
For example, one study found that lifestyle changes helped women manage their weight better without significant negative effects. Another analysis showed that these programs were linked to healthier weight outcomes for both mothers and babies.
Overall, the safety of such lifestyle changes appears positive, with studies highlighting their benefits and minimal risks.12345Why are researchers excited about this trial?
Researchers are excited about this lifestyle intervention for managing pregnancy weight gain because it combines personalized support and technology in a way that current options do not. Unlike traditional methods that rely heavily on in-person consultations, this approach uses a mix of telephone counseling with dieticians trained in motivational interviewing, alongside tech-based tools like automated texts and weekly emails. The intervention is tailored to each individual's progress, offering personalized text messages and one-on-one coaching if needed, which could make it more accessible and adaptable to women's busy lives during pregnancy.
What evidence suggests that this lifestyle intervention is effective for managing gestational weight gain?
Research has shown that lifestyle changes can help control weight gain during pregnancy. In this trial, participants in the Lifestyle Intervention arm will receive support through a mobile health tool, personalized messages, and coaching to manage their weight gain. A study with 17,596 participants found that combining healthy eating and exercise reduced weight gain by about 0.82 kg on average. Another analysis identified certain aspects of these lifestyle changes as particularly effective. This suggests that the approach used in this trial could help women manage their weight gain during pregnancy.23467
