Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Good Bowls, Good Bowls + App Nudges?

Research shows that using nudges, like signs or changing food placement, can encourage people to make healthier food choices, such as drinking more water or choosing healthier desserts. This suggests that similar strategies could help make the Good Bowls program more effective in promoting healthy eating.12345

Is the Healthy Meal Program + Tech Nudges for Healthy Nutrition safe for humans?

The research articles reviewed do not provide specific safety data for the Healthy Meal Program + Tech Nudges or its variations like Good Bowls. However, nudging strategies generally focus on encouraging healthier food choices and are not associated with safety risks.12467

How does the Healthy Meal Program + Tech Nudges treatment differ from other treatments for healthy nutrition?

This treatment is unique because it combines healthy meal options with technology-based nudges (reminders or prompts) to encourage healthier eating habits. Unlike traditional dietary interventions, it uses an app to provide personalized nudges, making it more interactive and potentially more engaging for participants.6891011

What is the purpose of this trial?

The goal of this clinical trial is to improve the health of blue-collar workers by providing subsidized healthy meals supported by nutrition education and behavioral nudges using mobile health and Bluetooth technology.The aim of this study is to:Randomize 240 individuals in 8-10 worksites to either Good Bowls alone or Good Bowls + Phone App nudges. Using a crossover design, the primary outcome is the score on a validated Mediterranean diet screener, with secondary outcomes including weight, blood pressure, carotenoid levels, and food security.Participants: Blue-collar workers in rural manufacturing plants.Procedures: Workers will be recruited from 8-10 worksites who will be initially randomized within each site to Good Bowls alone or Good Bowls + Phone App nudges. Initial assignment will be followed for four months, after which the groups will crossover for the subsequent four months. The investigators will collect survey data as well as some physiologic measures including skin scanning (non-invasive), weight, and blood pressure. Effects between groups will be determined.

Findings from Research

In a study involving 88 early childhood education centers, incorporating nudge strategies into workshop invitations did not significantly increase registration rates compared to generic invitations, with only 25% of the intervention group registering versus 20% in the control group.
The study found no significant differences in invitation recall or acceptability between the two groups, suggesting that low-intensity behavioral nudges may not be effective in promoting participation in nutrition education workshops.
