ABSTRACT
OBJECTIVES: To identify and evaluate the effect of interventions that used cell phones as a means to promote physical activity (PA). METHODS: The databases searched were MedLine/PubMed, Scopus, SPORTDiscus, PsycINFO, Science Direct, Lilacs, and SciELO. After removing duplicates, applying exclusion criteria, and checking the reference lists, 45 studies were reviewed. The Downs and Black (D&B) scale measured methodological quality, and a random effect model was used to compute the meta-analysis of PA by the reported unit (minutes per day or steps per day), delivery agent (application (APP), SMS, or other), and PA measurement (questionnaire, accelerometer, pedometer). RESULTS: Mobile phone-based PA interventions were efficient in increasing both minutes [10.49; CI (3.37-17.60); p = 0.004] and steps per day [735.17; CI (227.72-1242.61); p = 0.005] in adults when compared to baseline. Furthermore, APP-based interventions were able to increase the number of steps (p = 0.04) and minutes per day of PA (p = 0.04) in adults. Also, 85% of included manuscripts were classified as moderate- to high-quality articles. CONCLUSIONS: Mobile phone-based PA interventions, inclusive those delivery by APP, were effective to increase minutes and steps per day in adults.

O objetivo do estudo foi verificar a prática de atividades físicas e os fatores a ela associados em estudantes de Educação Física. Estudo longitudinal realizado com acadêmicos de uma Universidade Federal do sul do Brasil. Foram avaliados 81 estudantes dos cursos de licenciatura e bacharelado os quais responderam um questionário padronizado aplicado em dois períodos: início da graduação (2014) e início do segundo ano de curso (2015). O instrumento abordou questões sobre dados sociodemográficos, comportamentais e nutricional. O nível de atividade física foi avaliado nos domínios lazer e deslocamento através do International Physical Activity Questionnaire (IPAQ) versão longa. A análise estatística utilizou teste de qui-quadrado para comparação de proporções e teste de McNemar para dados pareados. A amostra apresentou maior frequência de ativos entre os indivíduos do sexo masculino, solteiros e não fumantes. Não houve diferença significativa de ativos entre cursos e entre os períodos avaliados. O período de um ano após o ingresso na universidade não mostrou diferenças na prática de atividade física, no entanto as baixas prevalências no domínio do lazer alertam para uma continuidade no acompanhamento, visto que esses indivíduos, além de se beneficiarem deste comporta-mento saudável, serão futuros disseminadores do mesmo.
The aim of the study was to verify the physical activity pratice and associated factors in physical education students. A longitudinal study was conducted with academics from a federal university in southern Brazil. We evaluated 81 students of bachelor's degree and licentiate's degree who answered a standardized questionnaire applied in two periods: early graduation (2014) and beginning of the second year course (2015). The questionnaire included sociodemographic, behavioral and nutritional questions. The level of physical activity was assessed in leisure and commuting domains through the International Physical Activity Questionnaire (IPAQ) long version. The statistical analysis used chis-quare test to compare proportions and McNemar test for paired data. The sample showed a higher frequency of actives among males, singles and nonsmokers. There was no significant difference in actives between courses and between periods. The period of one year after entry into the university showed no differences in physical activity, however the low prevalence in the leisure domain warn of continuity in monitoring, since these individuals, as well as to benefit from this healthy behavior, will be forthcoming disseminators of it.
