Hypothesis
Can a behavioral intervention improve physical activity and dietary practices among obese adults with additional risk factors?
Conclusion
The intervention procedures were found to be acceptable and feasible, but high attrition rates indicated the need for improvements.
Supporting Evidence
- Participants in the intervention group showed positive trends for most psychological, behavioral, and body composition outcomes.
- 34.6% of randomized participants were lost to follow-up due to high measurement burden.
- Scottish Index of Multiple Deprivation was a significant predictor of consent to participate.
Takeaway
This study tested a program to help overweight adults eat better and move more, but many people dropped out before finishing.
Methodology
A pilot single centre open-labelled outcome assessor-blinded randomised controlled trial.
Potential Biases
Participants from more deprived neighborhoods were less likely to consent.
Limitations
High attrition rates and measurement burden affected participant retention.
Participant Demographics
81 participants, 63% female, mean age 56.56 years, mean BMI 36.73.
