Around 20% of cases are linked to weight gain, excess weight and health behaviours. We designed a weight gain prevention, health behaviour intervention for young women at increased risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study comprised a single arm observational study over 2 months testing acceptability and usability of the intervention: online group welcome event, app and private Facebook group. Females aged 18\u201335 years at moderate or high risk of breast cancer (&gt;17% lifetime risk) were recruited via invite letters and social media posts. The app included behaviour change techniques and education content. Online questionnaires were completed at baseline, as well as at 1 and 2 months. We also assessed feasibility of study procedures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Both recruitment methods were successful. Thirty\u2010five women were recruited, 26% via social media posts. Median age was 33 (interquartile range = 28.2\u201334.5) years, the majority (94.1%) were of White ethnicity. Thirty\u2010four participants were included in the analyses, of which 94% downloaded the app. Median self\u2010monitoring logs per participant during the study period was 10.0 (interquartile range = 4.8\u201328.8). App quality mean (SD) score was 3.7 (0.6) at 1 and 2 months (scale: 1\u20135). Eighty\u2010nine per cent rated the app at average or above at 1 month and 75.0% at 2 months. Nineteen women (55.9%) joined the Facebook group and there were 61 comments and 83 reactions and votes from participants during the study period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This first iteration of the app and intervention was well received and is suitable to progress to the next stage of refining and further testing.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jhn.13347","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T02:04:43Z","timestamp":1721009083000},"page":"1170-1185","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An app promoting weight gain prevention via healthy behaviours amongst young women with a family history of breast cancer: Acceptability and usability assessment"],"prefix":"10.1111","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5656-1486","authenticated-orcid":false,"given":"Mary","family":"Pegington","sequence":"first","affiliation":[{"name":"Division of Cancer Sciences The University of Manchester Manchester UK"},{"name":"The Prevent Breast Cancer Research Unit, The Nightingale Centre Manchester University NHS Foundation Trust Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rhiannon E.","family":"Hawkes","sequence":"additional","affiliation":[{"name":"Manchester Centre for Health Psychology, School of Health Sciences University of Manchester Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Davies","sequence":"additional","affiliation":[{"name":"Division of Informatics, Imaging and Data Sciences The University of Manchester Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Mueller","sequence":"additional","affiliation":[{"name":"MRC Epidemiology Unit University of Cambridge Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony","family":"Howell","sequence":"additional","affiliation":[{"name":"Division of Cancer Sciences The University of Manchester Manchester UK"},{"name":"The Prevent Breast Cancer Research Unit, The Nightingale Centre Manchester University NHS Foundation Trust Manchester UK"},{"name":"Manchester Breast Centre, Oglesby Cancer Research Centre, The Christie NHS Foundation Trust University of Manchester Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Gareth Evans","sequence":"additional","affiliation":[{"name":"The Prevent Breast Cancer Research Unit, The Nightingale Centre Manchester University NHS Foundation Trust Manchester UK"},{"name":"Manchester Breast Centre, Oglesby Cancer Research Centre, The Christie NHS Foundation Trust University of Manchester Manchester UK"},{"name":"Genomic Medicine, Division of Evolution, Infection and Genomic Sciences The University of Manchester, St Mary's Hospital, Manchester University NHS Foundation Trust Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sacha J.","family":"Howell","sequence":"additional","affiliation":[{"name":"Division of Cancer Sciences The University of Manchester Manchester UK"},{"name":"The Prevent Breast Cancer Research Unit, The Nightingale Centre Manchester University NHS Foundation Trust Manchester UK"},{"name":"Manchester Breast Centre, Oglesby Cancer Research Centre, The Christie NHS Foundation Trust University of Manchester Manchester UK"},{"name":"Department of Medical Oncology The Christie NHS Foundation Trust Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David P.","family":"French","sequence":"additional","affiliation":[{"name":"Manchester Centre for Health Psychology, School of Health Sciences University of Manchester Manchester UK"},{"name":"Manchester Breast Centre, Oglesby Cancer Research Centre, The Christie NHS Foundation Trust University of Manchester Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9761-3089","authenticated-orcid":false,"given":"Michelle","family":"Harvie","sequence":"additional","affiliation":[{"name":"Division of Cancer Sciences The University of Manchester Manchester UK"},{"name":"The Prevent Breast Cancer Research Unit, The Nightingale Centre Manchester University NHS Foundation Trust Manchester UK"},{"name":"Manchester Breast Centre, Oglesby Cancer Research Centre, The Christie NHS Foundation Trust University of Manchester Manchester UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,7,14]]},"reference":[{"key":"e_1_2_12_2_1","unstructured":"Cancer Research UK.
