HealthDay News — Extended-contact, text-message-delivered interventions appear to be effective for weight management, according to a review published online in Obesity Reviews.

J.R. Job, from the University of Queensland in Brisbane, Australia, and colleagues conducted a systematic literature review to identify studies assessing the effectiveness of extended-contact, text message interventions for adults in supporting weight management. Seven studies were included in the meta-analysis.

The researchers found that, compared with a control, the pooled effect of the extended-contact intervention was −0.82 kg (1.81 lbs) (3 studies), but pooled within-group weight loss was −2.16 kg (4.7 lbs) during extended-contact interventions (6 studies). Compared with the 3 interventions considered to be “ineffective,” the 4 “effective” interventions were more likely to last longer than 12 weeks.

“Evidence from the small number of studies reviewed suggests that extended-contact, text-message-delivered interventions are effective,” the authors write. “Further research is required to elucidate effective intervention components and the longer-term impact on weight, diet, and physical activity behavior.”
