According to Gram Research analysis, mobile app health coaching for stomach cancer patients after surgery reduced breathing trouble and eating problems at 6 months compared to traditional dietitian counseling, with benefits most pronounced in younger patients, women, and those who actively used the app for at least 8 weeks.

Researchers studied 160 stomach cancer patients who had surgery to remove part or all of their stomach. Half received personalized health coaching through a mobile app, while the other half got traditional face-to-face counseling with dietitians. While both groups had similar eating difficulties one month after surgery, patients using the mobile app reported less trouble breathing, fewer eating problems at 6 months, and better body image feelings. The mobile coaching worked especially well for younger patients, women, and those who actively used the app for at least 8 weeks.

Key Statistics

In a randomized controlled trial of 160 stomach cancer patients (2020-2022), mobile app users reported significantly less trouble breathing throughout the entire study period compared to those receiving traditional face-to-face dietitian counseling.

Among mobile app users in the study, approximately two-thirds were considered active users who engaged with the app for at least 8 weeks out of the 3-month coaching period, and these active users reported better overall health outcomes.

Mobile app coaching users experienced fewer eating restrictions at the 6-month follow-up mark and reported better body image feelings at 3 months post-surgery compared to the traditional counseling group in this 160-patient study.

The Quick Take

  • What they studied: Whether mobile app coaching helps stomach cancer patients recover better after surgery compared to traditional dietitian visits
  • Who participated: 160 stomach cancer patients who had surgery between 2020-2022, with an average age around 60 years
  • Key finding: Mobile app users had less breathing trouble, fewer long-term eating problems, and better feelings about their body image compared to those getting traditional counseling
  • What it means for you: If you’re recovering from stomach surgery, mobile health coaching might help you feel better and adapt to eating changes, especially if you use it regularly

The Research Details

This was a randomized controlled trial, which is considered the gold standard for medical research. Researchers randomly assigned 180 stomach cancer patients to either receive mobile app coaching or traditional face-to-face counseling after their surgery. The mobile app group got personalized advice from health coaches based on daily health information they recorded in the app for 3 months. The traditional group met with dietitians at 1 and 3 months after surgery.

This study design helps ensure that any differences between groups were due to the type of coaching, not other factors. By comparing mobile coaching directly to the current standard of care, researchers could determine if the new approach actually works better.

The study followed patients for a full year and used well-established questionnaires to measure quality of life. However, about 11% of patients dropped out, and the main goal of reducing eating problems at one month wasn’t achieved, which somewhat limits the findings.

What the Results Show

The study’s main goal was to see if mobile coaching reduced eating restrictions one month after surgery, but both groups had similar eating difficulties at this time point. However, mobile coaching users experienced several other benefits throughout their recovery. They reported less trouble breathing during the entire study period, had fewer eating restrictions at the 6-month mark, and felt better about their body image 3 months after surgery. About two-thirds of mobile app users were considered ‘active users’ who used the app for at least 8 weeks out of the 3-month coaching period.

The benefits of mobile coaching weren’t the same for everyone. Younger patients under 60, women, and those who had partial stomach removal (distal gastrectomy) seemed to benefit most from the mobile coaching approach. Among mobile app users, those who actively engaged with the app reported better overall health compared to those who used it less frequently. Interestingly, neither group showed significant differences in body weight, muscle mass, or blood nutrition markers.

This appears to be one of the first studies to test mobile health coaching specifically for stomach cancer patients after surgery. Previous research has shown mobile coaching helps people with diabetes and other chronic conditions, and this study suggests it may also help cancer patients during recovery.

The study couldn’t prove that mobile coaching was better for the main outcome they were testing. Some patients dropped out, and the benefits were mainly seen in certain subgroups rather than all patients. The study also didn’t measure long-term outcomes beyond one year, so we don’t know if the benefits last.

The Bottom Line

Mobile health coaching may be a helpful addition to traditional care for stomach cancer patients after surgery, particularly for younger patients, women, and those who are willing to actively engage with the technology. However, it shouldn’t replace traditional medical care and dietitian consultations.

Stomach cancer patients preparing for or recovering from surgery, their families, and healthcare teams should consider mobile coaching as a supportive tool. This approach may be especially beneficial for tech-comfortable patients under 60 and women.

Benefits may start appearing around 3 months after surgery, with eating improvements potentially continuing through 6 months. Consistent daily use of the app for at least 8 weeks appears important for seeing results.

Frequently Asked Questions

Does mobile app coaching help stomach cancer patients recover better after surgery?

Mobile app coaching reduced breathing trouble and eating problems at 6 months compared to traditional counseling. Benefits were strongest in younger patients under 60, women, and those who actively used the app for at least 8 weeks.

Who benefits most from mobile health coaching after stomach cancer surgery?

Younger patients under 60, women, and those with partial stomach removal showed the greatest benefits. Active app users who engaged daily for at least 8 weeks experienced better overall health outcomes than less frequent users.

How long does it take to see benefits from mobile coaching after stomach surgery?

Benefits appeared around 3 months post-surgery, with eating improvements continuing through 6 months. Consistent daily app use for at least 8 weeks appears necessary to achieve measurable results.

Can mobile app coaching replace traditional dietitian care after stomach cancer surgery?

No, mobile coaching should not replace traditional medical care and dietitian consultations. It works best as a supportive tool alongside conventional care for stomach cancer recovery.
