Outcomes of a 12-Month Technology-Based Intervention to Promote Weight Loss in Adolescents at Risk for Type 2 Diabetes
Open accessAbstract
Background: Obese adolescents are at risk for type 2 diabetes mellitus (T2DM). Obesity interventions delivered through media, such as the web and text messages [short message service (SMS)] may be beneficial when targeting obese adolescents. Methods: A randomized controlled trial, Pace-Internet for Diabetes Prevention Intervention (PACEi-DP), compared three forms of an obesity intervention to usual care (UC): (a) website only (W); (b) website, monthly group sessions, and follow-up calls (WG); and (c) website and SMS (WSMS). Participants were overweight or obese adolescents at risk for T2DM ( n = 101; age 12–16 years; mean body mass index (BMI) percentile = 97.6; 74.3% Hispanic). In addition to the website, WSMS participants received SMS supporting intervention goals and behavioral strategies and communicated via SMS with a case manager. WG participants had additional group activities related to weight loss and received follow-up calls from a health coach. UC participants were given printed materials and encouraged to attend three initial group sessions. Repeated measures mixed model regression analyses tested treatment effects for anthropometric, behavioral, and behavioral change strategy outcomes. Results: There were no treatment effects for BMI, adiposity, physical activity, or diet at 12 months. Treatment effects were observed for sedentary behavior, with the W arm having a greater decrease in sedentary behavior (4.9 to 2.8 h/day) than the UC arm ( p = .006). Conclusion: Although not sufficient to produce weight loss, the combination of web intervention and group sessions with telephone follow-up yielded improvements in sedentary behavior and in the use of behavior change strategies expected to lead to behavior change.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
