Both intervention and standard care received routine antenatal care. The primary outcome was effectiveness in reducing excess GWG, and the secondary outcomes were reach, adoption, implementation, and maintenance and maternal and neonatal outcomes using the RE\u2010AIM framework.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For the \u201cReach\u201d aspect, 90% of eligible women were included (<jats:italic>N<\/jats:italic>\u2009=\u2009404; <jats:italic>n<\/jats:italic>\u2009=\u2009202 intervention and <jats:italic>n<\/jats:italic>\u2009=\u2009202 standard care). For the \u201cEfficacy\u201d aspect, there were no differences in proportion exceeding GWG recommendations or mean GWG between groups. Secondary analysis excluding women with gestational diabetes showed that a lower proportion of women in the intervention group had GWG above recommendations (\u03b2 coefficient 0.51, 95% CI: 0.27 to 0.97; <jats:italic>p<\/jats:italic>\u2009=\u20090.04), with less GWG (\u03b2 coefficient \u22121.93\u2009kg, 95% CI: \u22123.63 to \u22120.24; <jats:italic>p<\/jats:italic>\u2009=\u20090.03). For the \u201cAdoption\u201d aspect, qualitative analysis of staff\/participants demonstrated strong support for service. For the \u201cImplementation\u201d aspect, strong fidelity (implementation according to study plan) and staff\/participant acceptability were observed.
