Background: The use of mobile phone apps for improving lifestyles has become generalized in the population, although little is still known about their effectiveness health. Objective: We evaluate effect adding an app to standard counseling on increased physical activity (PA) and adherence Mediterranean diet, 3 months after implementation. Methods: A randomized, multicenter clinical trial was carried out. total 833 participants were recruited six primary care centers Spain through random sampling: 415 app+counseling group 418 only group. Counseling PA diet given both groups. additionally received training designed promote over a 3-month period. measured with 7-day Physical Activity Recall (PAR) questionnaire accelerometer; assessed using Diet Adherence Screener questionnaire. Results: Participants predominantly female (249/415, 60.0%) (268/418, 64.1%) groups, mean age 51.4 (SD 12.1) 52.3 12.0) years, respectively. Leisure-time moderate-to-vigorous (MVPA) by PAR (mean 29, 95% CI 5-53 min/week; P=.02) but not 17.4, –18 53 P=.38). No differences increase found between two accelerometer recorded decrease groups: MVPA –55.3 (95% –75.8 –34.9) min/week –30.1 –51.8 –8.4) groups (8.4% 10.4% group), score 0.42 0.53 points, respectively (P<.001), no difference (P=.86). Conclusions: more than group, when comparing accompanied printed materials appears be effective does adherence.
