abstract: 'ObjectivesSocial scientists have demonstrated that family health work is interlinked with heteronormative gender inequities. Yet family-based public health interventions rarely incorporate a gender transformative approach or address heteronormativity as a potential health barrier in North America. Instead, attention to gender surfaces primarily in family health interventions conducted in low- to middle-income countries with majority Black and racialized populations. The objective of this article is to establish the importance of designing health interventions that account for heteronormative relations in Ontarian families by drawing on empirical data from the Guelph Family Health Study (GFHS).MethodsWe draw on data (February-October 2019) from (1) semi-structured interviews with 20 families and with 4 health educators facilitating the GFHS home visits and (2) observational data of 11 GFHS home visits and 1 health educator training day. Informed by gender transformation theory, data were analyzed and coded to understand the impact of gender, sexuality, and place in family health interventions.ResultsPre-existing heteronormative parenting relations were reinforced through GFHS participation: the GFHS was mother-led, increasing some mothers'' stress levels. Fathers tended to consider paid work a justification for disengaging from the GFHS, and their detachment sometimes obstructed mothers'' intervention efforts. Health educators (all women) were caught in these relations, feeling like because of their gender, they were viewed by parents as confidants and marriage counsellors.ConclusionFindings emphasize the need for expanding the epistemic and methodological approaches to family-based health interventions, changing the demographic and geographic emphasis within the field, and designing interventions that focus on societal-level changes. Heterosexuality has not been analyzed as a risk factor within the public health field, but our findings indicate the need for further study.' affiliation: 'Gruson-Wood, J (Corresponding Author), Univ Guelph, Social Practice \& Transformat Change Program, Guelph, ON, Canada.
