Hypothesis
Does a web-based nutrition education program improve weight, blood pressure, and dietary habits over 12 months?
Conclusion
The study found that using an internet-based nutrition education program led to significant weight loss, lower blood pressure, and improved dietary habits after one year.
Supporting Evidence
- Participants who used the website more frequently experienced greater weight loss.
- Weight change for overweight/obese participants was an average of -4.2 lbs.
- Systolic blood pressure decreased by 6.8 mmHg in participants with hypertension.
- Participants reported increased fruit and vegetable intake after 12 months.
- 26% of original enrollees continued using the program after one year.
Takeaway
This study shows that a website can help people eat better and lose weight, even without meeting a doctor in person.
Methodology
Participants enrolled in a web-based nutrition program and provided self-reported data on weight, blood pressure, and food intake over 12 months.
Potential Biases
Self-selection bias may have influenced the results, as only those who continued using the website were analyzed.
Limitations
The study relied on self-reported data without objective measurements and lacked a control group.
Participant Demographics
Participants were mostly white, highly educated, and included both males and females aged 18-73 years.
