RESUMEN
BACKGROUND: The Developmental Origins of Health and Disease (DOHaD) paradigm emphasizes the significance of early life factors for the prevention of chronic health conditions, like type 2 diabetes (T2DM) and obesity, which disproportionately affect First Nations communities in Canada. Despite increasing DOHaD research related to maternal health during pregnancy, early childhood growth patterns, and infant feeding practices with many populations, data from First Nations communities in Canada are limited. In partnership with Sandy Lake First Nation, the aims of this project were to characterize birthweights and growth patterns of First Nations infants/children over the first 6 years of life and to study the impact of maternal and infant social and behavioral factors on birthweight and growth trajectories. METHODS: We recruited 194 families through community announcements and clinic visits. Infant/child length/height and weight were measured at 1 and 2 weeks; 1, 2, 6, 12, and 18 months; and 2, 3, 4, 5 and 6 years. Maternal and infant/child questionnaires captured data about health, nutrition, and social support. Weight-for-Age z-score (WAZ), Height-for-Age z-score (HAZ), and BMI-for-Age z-score (BAZ) were calculated using WHO reference standards and trajectories were analyzed using generalized additive models. Generalized estimating equations and logistic regression were used to determine associations between exposures and outcomes. RESULTS: WAZ and BAZ were above the WHO mean and increased with age until age 6 years. Generalized estimating equations indicated that WAZ was positively associated with age (0.152; 95% CI 0.014, 0.29), HAZ was positively associated with birthweight (0.155; 95% CI 0.035, 0.275), and BAZ was positively associated with caregiver's BMI (0.049; 95% CI 0.004, 0.090). There was an increased odds of rapid weight gain (RWG) with exposure to gestational diabetes (OR: 7.47, 95% CI 1.68, 46.22). Almost 70% of parents initiated breastfeeding, and breastfeeding initiation was modestly associated with lower WAZ (-0.18; 95% CI -0.64, 0.28) and BAZ (-0.23; 95% CI -0.79, 0.34). CONCLUSIONS: This work highlights early life factors that may contribute to T2DM etiology and can be used to support community and Indigenous-led prevention strategies.

INTRODUCTION: Major inequities exist in levels of health and wellbeing, availability, and access to healthcare services between seniors of Indigenous and non-Indigenous background in Ontario. First Nations elders are 45-55% more frail than the average senior in Ontario. Additionally, needed rehabilitation services are not easily accessible or available in the first language of most First Nations elders within their home communities. A literature review demonstrated community-based rehabilitation assistant models had been successfully developed and implemented in regions facing similar equity and access challenges. Building on these findings, a needs assessment was conducted to capture unique needs and requirements in Northwestern Ontario relating to rehabilitation among First Nations elders. METHODS: The needs assessment resulted in four First Nations, three Indigenous health organizations, three rehabilitation health organizations, and two academic institutions iteratively developing and evaluating curriculum for a Community Rehabilitation Worker (CRW) program in treaty territories 5, 9, and Robinson-Superior. The goal of the program is to train local CRWs, familiar with local languages and cultures, to provide rehabilitative services that support ageing in place, health, wellbeing, and quality of life for First Nations elders. The study employed a community participatory action research approach aligning with the OCAP® (Ownership, Control, Access, and Possession) framework for working with Indigenous populations. Seventeen community partners were active participants in the program development, evaluation, and adaptation of the CRW curriculum. Feedback was received through advisory committee meetings, surveys, and individual and group interviews. RESULTS: All 101 participants agreed, across all curriculum modules, that (1) the time allotment was realistic; (2) instructional materials, activities, and resources were appropriate and easy to understand; (3) evaluation activities accurately measured learning; and (4) participants identifying as Indigenous felt that Indigenous culture was adequately reflected. The qualitative findings highlighted the importance of incorporating culture, spirituality, traditions, local language use, and reintegration of First Nations elders into traditional activities and community activities for both the CRW curriculum and rehabilitation efforts. The need for locally available First Nations, elder-focused mental health support, transportation options, and gathering spaces such as those commonly seen in urban areas was also highlighted. CONCLUSION: The process of iteratively developing and evaluating a CRW program resulted in a Northwestern Ontario college welcoming the first cohort of students to the CRW program in March 2022. The program is co-facilitated with a First Nations Elder and includes components of local culture, language, and the reintegration of First Nations elders into community as part of the rehabilitation efforts. In addition, to appropriately support the quality of life, health, and wellbeing of First Nations elders, the project team called upon provincial and federal governments to work with First Nations to make available dedicated funding to address inequities in resources available to First Nations elders in Northwestern Ontario urban and First Nations remote communities. This included elder-focused transportation options, mental health services, and gathering places. The program implementation will be evaluated with the first cohort of CRWs for further adaptations considering potential scale and spread. As such, the project and findings may also represent a resource for others wishing to pursue similar development using participatory approaches in rural and remote communities both nationally and internationally.
