NCT01650337 · View on ClinicalTrials.gov ↗
Study Summary
BACKGROUND: The nascent field of mobile health (mHealth) is expanding with impressive speed. In March 2012, experts estimated that 40,000 health related smartphone applications were on the market but little is known about the effectiveness of these programs. To our knowledge, no studies have evaluated whether weight loss can be successfully achieved through use of a smartphone application or how these applications could be used in primary care practice. PURPOSE: To evaluate the effectiveness of a popular, free smartphone application for weight loss and calorie counting in a primary care setting. METHODS: The first phase of this study involved a community based participatory approach to select the intervention. Patient focus groups were conducted and analyzed to explore patients' preferences regarding various text-message versus smartphone programs. The second phase of this study, described here, will be a randomized controlled trial with overweight primary care patients exposed to one of two conditions for 6 months: (1) usual care; (2) usual care plus smartphone application, which includes instructing participants on how to use the application and encouraging them to use the applications' reminders and social networking features. The primary outcome of interest is weight change at 3 and 6 months. Two-sample t-test or Wilcoxon rank sum test will be used to compare weight change between groups, as appropriate. ANCOVA models will be used to examine weight change after adjusting for covariates such as education, sex and age. Repeated measures analysis will be carried out to compare weight change between the groups using baseline, 3 month and 6 month data. In addition to an intent-to-treat analysis, the investigators will also conduct a "treatment received" analysis, adjusting for the extent of application use in both the intervention and control arms. CONCLUSIONS: This study will demonstrate whether a smartphone application introduced in primary care settings and inc

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01650337
The ClinicalTrials.gov registry entry for NCT01650337 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 212 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, Los Angeles, which has 829 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Overweight appearing as the primary indexed condition, and to 1 intervention — of which Smartphone Application is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01650337 reports 2 study locations spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
