Abstract

BACKGROUND: The Internet has potential as a medium for health behavior change programs, but no controlled studies have yet evaluated the impact of a fully automated physical activity intervention over several months with real-time objective feedback from a monitor. OBJECTIVE: The aim was to evaluate the impact of a physical activity program based on the Internet and mobile phone technology provided to individuals for 9 weeks. METHODS: A single-center, randomized, stratified controlled trial was conducted from September to December 2005 in Bedfordshire, United Kingdom, with 77 healthy adults whose mean age was 40.4 years (SD = 7.6) and mean body mass index was 26.3 (SD = 3.4). Participants were randomized to a test group that had access to an Internet and mobile phone-based physical activity program (n = 47) or to a control group (n = 30) that received no support. The test group received tailored solutions for perceived barriers, a schedule to plan weekly exercise sessions with mobile phone and email reminders, a message board to share their experiences with others, and feedback on their level of physical activity. Both groups were issued a wrist-worn accelerometer to monitor their level of physical activity; only the test group received real-time feedback via the Internet. The main outcome measures were accelerometer data and self-report of physical activity. RESULTS: At the end of the study period, the test group reported a significantly greater increase over baseline than did the control group for perceived control (P < .001) and intention/expectation to exercise (P < .001). Intent-to-treat analyses of both the accelerometer data (P = .02) and leisure time self-report data (P = .03) found a higher level of moderate physical activity in the test group. The average increase (over the control group) in accelerometer-measured moderate physical activity was 2 h 18 min per week. The test group also lost more percent body fat than the control group (test group: -2.18, SD = 0.59; control group: -0.17, SD = 0.81; P = .04). CONCLUSIONS: A fully automated Internet and mobile phone-based motivation and action support system can significantly increase and maintain the level of physical activity in healthy adults.

  • Studies on the effectiveness of SMS messages for health promotion have also shown improvements in the outcomes of care.

    “Studies on the effectiveness of SMS messages for health promotion have also shown improvements in the outcomes of care.”

    From Impacts of e-health on the outcomes of care in low- and middle-income countries: where do we go from here? (2012) · cites this paper as [53]

    The Abstract Results report greater physical activity and a reduction in percent body fat in the intervention group. But the Methods describe text messages as optional components of a broader Internet, email, and mobile-phone program, and the Discussion says the study cannot determine which components were effective. It therefore does not show that SMS messages themselves improved outcomes of care. (LLM, conf=0.88)

  • Social cognitive theory was the main theoretical basis for the weight loss, diet, and physical activity interventions, though one study cited the theory of planned behavior.

    “Consistent with the more general weight loss intervention literature, Social Cognitive Theory was the primary theoretical basis for these interventions although the Theory of Planned Behavior was cited by one study [38].”
  • Prompts hold great promise, particularly when mobile phones, PDAs, pagers, and other wireless devices are integrated.

    “The use of prompts has significant potential, particularly given the possible integration of mobile phones, PDAs, pagers, and other wireless devices that can all be employed in the deliverance of prompts [29, 30].”

    From A Behavior Change Model for Internet Interventions (2009) · cites this paper as [29]

  • Social referencing engagement type has been applied in only 4 studies.

    “both the social presentation [7,48,61,68] and social referencing [7,8,48,85] engagement types have been applied in only 4 studies.”
  • Mobile health promotion interventions using text messaging or portable devices have produced favorable outcomes in weight loss, physical activity, smoking cessation, and anxiety.

    “These interventions have produced favorable outcomes in areas such as weight loss, physical activity, smoking cessation, and anxiety [3-7].”

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.
