Tailored automatic recommendations mimic interpersonal counseling and are promising strategies to be considered for health promotion programs. This study aimed to develop and test a mobile recommendation system for parents of preschool children identified with overweight\/obesity at health care centers. Evidence-based recommendations related to children\u2019s eating, drinking, moving, and sleeping habits were developed and tested using a questionnaire. A pilot study was conducted in a health care center to test how using an app with those tailored recommendations, in video format, influenced parents\u2019 perceptions of the child\u2019s weight status and their knowledge about the guidelines, compared to a control group. The chi-squared test was used for categorical variables and the Mann\u2013Whitney U test for continuous variables (p &lt; 0.05). A high proportion of parents were already informed about the guidelines, but their children were not meeting them. After watching the tailored recommendations, there was an increased knowledge of the guideline on water intake, but there was no improvement in the perception of the child\u2019s excessive weight. Parents may benefit from a mobile-based tailored recommendation system to improve their knowledge about the guidelines. However, there is a need to work with parents on motivation to manage the child\u2019s weight with additional strategies.<\/jats:p>","DOI":"10.3390\/ejihpe10030057","type":"journal-article","created":{"date-parts":[[2020,8,10]],"date-time":"2020-08-10T05:07:23Z","timestamp":1597036043000},"page":"779-794","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A Mobile-Based Tailored Recommendation System for Parents of Children with Overweight or Obesity: A New Tool for Health Care Centers"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4455-5895","authenticated-orcid":false,"given":"Lisa","family":"Afonso","sequence":"first","affiliation":[{"name":"Faculty of Psychology and Educational Sciences and Center for Psychology, University of Porto, Rua Alfredo Allen, 4200-135 Porto, Portugal"}]},{"given":"Rui","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Porto, and INESC TEC, Rua Doutor Roberto Frias, 4200-465 Porto, Portugal"}]},{"given":"Joana","family":"Castro","sequence":"additional","affiliation":[{"name":"Maia-Valongo Health Centre Group, Avenida Lu\u00eds de Cam\u00f5es, n.\u00ba 290, 3.\u00ba Andar, 4474-004 Maia, Portugal"}]},{"given":"Nuno","family":"Parente","sequence":"additional","affiliation":[{"name":"Maia-Valongo Health Centre Group, Avenida Lu\u00eds de Cam\u00f5es, n.\u00ba 290, 3.\u00ba Andar, 4474-004 Maia, Portugal"}]},{"given":"Carina","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Maia-Valongo Health Centre Group, Avenida Lu\u00eds de Cam\u00f5es, n.\u00ba 290, 3.\u00ba Andar, 4474-004 Maia, Portugal"}]},{"given":"Ana","family":"Fraga","sequence":"additional","affiliation":[{"name":"Maia-Valongo Health Centre Group, Avenida Lu\u00eds de Cam\u00f5es, n.\u00ba 290, 3.\u00ba Andar, 4474-004 Maia, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4526-4272","authenticated-orcid":false,"given":"Sandra","family":"Torres","sequence":"additional","affiliation":[{"name":"Faculty of Psychology and Educational Sciences and Center for Psychology, University of Porto, Rua Alfredo Allen, 4200-135 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,7]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2018).
