Governments play a major role in creating and supporting a healthy school environment and should prioritise actions to improve children\u2019s health. Sintra Grows Healthy aims to promote healthy lifestyles to prevent childhood obesity and improve children\u2019s health-related quality of life and social and emotional skills, through the development of a school evidence-based and sustainable model.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This protocol describes a quasi-experimental design and community-based participatory research. The participants included in the study are the school community of Portuguese public primary schools from the municipality of Sintra. Data will be collected on demographic and socio-economic characterization, nutritional status, eating habits and behaviours, physical activity, sedentary behaviours and sleep, health-related quality of life, and social and emotional skills.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Discussion<\/jats:title>\n                <jats:p>There is evidence to support interventions in school settings as strategies for obesity prevention. Up-to-date homogeneous and community-based interventions for preventing childhood obesity are lacking, therefore Sintra Grows Healthy intends to fill this gap. Furthermore, Sintra Grows Healthy aims to contribute with relevant scientific findings that will allow the development of better strategies for policymakers and society to manage this major public health problem.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12889-020-09715-0","type":"journal-article","created":{"date-parts":[[2020,10,27]],"date-time":"2020-10-27T11:03:50Z","timestamp":1603796630000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A school-based intervention for a better future: study protocol of Sintra Grows Healthy"],"prefix":"10.1186","volume":"20","author":[{"given":"Raquel J.","family":"Ferreira","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7328-1817","authenticated-orcid":false,"given":"Telma","family":"Nogueira","sequence":"additional","affiliation":[]},{"given":"Vit\u00f3ria","family":"Dias da Silva","sequence":"additional","affiliation":[]},{"given":"Mariana","family":"Li\u00f1an Pinto","sequence":"additional","affiliation":[]},{"given":"Joana","family":"Sousa","sequence":"additional","affiliation":[]},{"given":"Ana Margarida","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"Paulo Jorge","family":"Nogueira","sequence":"additional","affiliation":[]},{"given":"Rute","family":"Borrego","sequence":"additional","affiliation":[]},{"given":"Ana","family":"Raposo","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Martins","sequence":"additional","affiliation":[]},{"given":"Marcos","family":"Onofre","sequence":"additional","affiliation":[]},{"given":"Adilson","family":"Marques","sequence":"additional","affiliation":[]},{"given":"Ant\u00f3nio","family":"Rodrigues","sequence":"additional","affiliation":[]},{"given":"Ana","family":"Quit\u00e9rio","sequence":"additional","affiliation":[]},{"given":"Ant\u00f3nio","family":"Pereira","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2020,10,27]]},"reference":[{"key":"9715_CR1","doi-asserted-by":"publisher","first-page":"2627","DOI":"10.1016\/S0140-6736(17)32129-3","volume":"390","author":"L Abarca-G\u00f3mez","year":"2017","unstructured":"Abarca-G\u00f3mez L, Abdeen ZA, Hamid ZA, Abu-Rmeileh NM, Acosta-Cazares B, Acuin C, et al.
