Although pregnancy may motivate lifestyle change in both mothers and partners, evidence on partner health behaviour change and within-couple alignment remains limited. Antenatal data from the Growing Up in New Zealand cohort were used to describe health behaviour changes among mothers\n                    <jats:italic>(n<\/jats:italic>\n                    = 6822) and partners (\n                    <jats:italic>n<\/jats:italic>\n                    = 4401), and to examine associations between selected dietary changes within mother\u2013partner dyads\n                    <jats:italic>(n<\/jats:italic>\n                    = 1195). Measures included changes in physical activity, alcohol use, smoking, and diet [avoidance of sugar-sweetened beverages (SSBs) and fast foods, and the addition of fruits and vegetables]. Associations were examined using multivariate Poisson regression models with robust variance. Most mothers (73.7%) remained consistently active or inactive during pregnancy, while 43.4% of partners reported changes in activity. Around 43% of both mothers and partners reduced or stopped alcohol use. Nearly half of smoking mothers quit, and two-thirds of smoking partners reduced or quit smoking. For diet, 22.9% and 30.7% of mothers avoided SSBs and fast foods, respectively, and 15.8% added fruits and\/or vegetables; respective figures for partners were 13.2%, 9.9%, and 19.2%. Significant dyadic associations were observed for avoiding SSBs (Prevalence ratio [PR]: 1.37, 95% confidence interval [CI]: 1.04\u20131.79) and for adding fruits and\/or vegetables to diets (PR: 2.05, 95% CI: 1.59\u20132.65). These findings indicate that pregnancy may represent a shared context for health behaviour change within households and highlight the potential value of partner-inclusive antenatal approaches.\n                  <\/jats:p>","DOI":"10.1017\/s2040174426100798","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T11:56:43Z","timestamp":1791374203000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Mothers\u2019 and partners\u2019 changes in health behaviours during pregnancy: observations from the\n                    <i>Growing Up in New Zealand Cohort<\/i>"],"prefix":"10.1017","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1275-4072","authenticated-orcid":false,"given":"Teresa","family":"Gontijo de Castro","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03b94tp07","id-type":"ROR","asserted-by":"publisher"}],"name":"The University of Auckland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela","family":"Lee","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03b94tp07","id-type":"ROR","asserted-by":"publisher"}],"name":"The University of Auckland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beng In","family":"Loh","sequence":"additional","affiliation":[{"name":"Universiti Sains Malaysia - Kampus Kesihatan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Gillies","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03b94tp07","id-type":"ROR","asserted-by":"publisher"}],"name":"The University of Auckland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clare","family":"Wall","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03b94tp07","id-type":"ROR","asserted-by":"publisher"}],"name":"The University of Auckland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,10,7]]},"reference":[{"key":"S2040174426100798_ref39","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-023-49986-2"},{"key":"S2040174426100798_ref44","doi-asserted-by":"publisher","DOI":"10.1111\/1753-6405.13216"},{"key":"S2040174426100798_ref46","doi-asserted-by":"publisher","DOI":"10.1093\/alcalc\/ags042"},{"key":"S2040174426100798_ref50","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwh090"},{"key":"S2040174426100798_ref29","first-page":"386","article-title":"Stress, depression, social support, and eating habits reduce diet quality in the first trimester in low-income women: a pilot study","volume":"15","author":"Fowles","year":"2012","journal-title":"Public Health Nutr"},{"key":"S2040174426100798_ref23","doi-asserted-by":"publisher","DOI":"10.1017\/S136898000800178X"},{"key":"S2040174426100798_ref27","doi-asserted-by":"publisher","DOI":"10.1249\/01.MSS.0000078924.61453.FB"},{"key":"S2040174426100798_ref13","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.031809.130727"},{"key":"S2040174426100798_ref17","first-page":"1224","article-title":"Challenging gender inequity through male involvement in maternal and newborn health","volume":"10","author":"Comrie-Thomson","year":"2015","journal-title":"Glob Public Health"},{"key":"S2040174426100798_ref43","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/dyw029"},{"key":"S2040174426100798_ref18","doi-asserted-by":"publisher","DOI":"10.1080\/16549716.2018.1449724"},{"key":"S2040174426100798_ref47","unstructured":"47.
