Explore the feasibility of an online behavioral weight management program for college students.
The program focused on behavioral strategies to modify eating and exercise behaviors of students interested in losing weight and/or developing a healthy lifestyle. Specific tools included weekly chat meetings with a facilitator, calorie and fat gram recommendations, daily food logs, and exercise guidance.
Three hundred thirty-six students participated from 2 northeastern universities. Overweight/obese students wanting to lose weight had a mean body mass index of 30.6 kg/m(2) at baseline and lost an average of 5.1 ± 6.0 lbs. Those of healthy weight wanting to lose weight had a mean body mass index of 22.0 kg/m(2) at baseline and lost an average of 1.8 ± 3.2 lbs. Twenty-three percent of students lost > 5% of their baseline weight.
Use of an online behavioral weight management program may be a feasible way to help college students develop healthy eating and exercise behaviors.
[Show abstract][Hide abstract] ABSTRACT: A major goal of our study was to identify the associations between lifestyle factors and obesity in adolescents and young adults at risk by surveying students in Inner Mongolia Medical University. A second goal was to determine these factors differed by gender.
Students grade 1-3 in Inner Mongolia Medical University.
5471 grade 1-3 medical students, composed of 3891 female and 1580 male students. Students with body mass index (BMI) ≥25 were defined as overweight.
BMI for male students was 22.1±2.9 and 21.2±2.2 for female students. The prevalence of overweight was 7.6%, with the prevalence being higher for male students compared with females, urban higher than rural and being an only child higher than having sibling children. For male students, urban residence was a risk factor, while for female students being an only child and staying up at night were risk factors, with physical activity a protective factor. A dose-dependency relationship was found between physical fitness and overweight prevalence.
This study shows that being an only child and resident in an urban area are risk factors; staying up late and lack of physical activities increased the risk of being overweight. BMI was associated with declines in physical fitness. Our study provides more insight into adolescent obesity problems.

[Show abstract][Hide abstract] ABSTRACT: Objective
To compare the effectiveness of online delivery of a weight management program using synchronous (real-time), distance-education technology to in-person delivery.
Synchronous, distance-education technology was used to conduct weekly sessions for participants with a live instructor. Program effectiveness was indicated by changes in weight, body mass index (BMI), waist circumference, and confidence in ability to eat healthy and be physically active.
Online class participants (n = 398) had significantly greater reductions in BMI, weight, and waist circumference than in-person class participants (n = 1,313). Physical activity confidence increased more for in-person than online class participants. There was no difference for healthy eating confidence.
Conclusions and Implications
This project demonstrates the feasibility of using synchronous distance-education technology to deliver a weight management program. Synchronous online delivery could be employed with no loss to improvements in BMI, weight, and waist circumference.

[Show abstract][Hide abstract] ABSTRACT: The Internet continues to serve as an ideal venue for health education interventions promoting behavior change. Due to the progressive expansion in online education programs, new methodologies that contribute across health education and program planning continuums are needed.
This ecologic study investigated the change in student dietary behav-ior and food choices following an original online education intervention that introduced the Mediterranean diet (MD) in a community college in Houston, Texas. A non-probability convenience sample (n=65) provided pretest-posttest data measuring knowledge of and attitudes toward the MD. The intervention was incorporated into an undergraduate nutrition course, delivered entirely online and evaluated using the Mediterranean Diet Quality Index (KIDMED) survey.
The intervention improved total participant population from a mean KIDMED score of poor (4.12) to a mean score of high (8.45) indicating an increase in knowledge of MD dietary guidelines and a positive shift in favorable attitude, particularly among men.
This study provides a unique pedagogical illustration of online learn-ing that introduce a specific evidence-based dietary guideline to a college student population. A detailed discussion of findings and lessons learned is provided.
