Impact of Maternal Health Behaviours and Social Conditions on Infant Diet at Age 1-Year: Results from a Prospective Indigenous Birth Cohort in Ontario, Canada.

Background: Understanding the impact of maternal health behaviours and social conditions on childhood nutrition is important to inform strategies to promote health during childhood. Objective: To describe how maternal health sociodemographic factors (e.g., socioeconomic status, education), health behaviours (e.g., diet), and traditional health care use during pregnancy impact infant diet at age 1-year. Methods: Data were collected from the Indigenous Birth Cohort (ABC) study, a prospective birth cohort formed in partnership with an Indigenous community-based Birthing Centre in southwestern Ontario, Canada. 110 mother-infant dyads are included in the study and were enrolled between 2012 and 2017. Multiple linear regression analyses were performed to understand factors associated with infant diet scores at age 1-year, with a higher score indicating a diet with more healthy foods. Results: The mean age of women enrolled during pregnancy was 27.3 (5.9) years. Eighty percent of mothers had low or moderate social disadvantage, 47.3% completed more than high school education, and 70% were cared for by a midwife during their pregnancy. The pre-pregnancy body mass index (BMI) was <25 in 34.5% of women, 15.5% of mothers smoked during pregnancy, and 14.5% of mothers had gestational diabetes. Being cared for by an Indigenous midwife was associated with a 0.9-point higher infant diet score (p = 0.001) at age 1-year, and lower maternal social disadvantage was associated with a 0.17-point higher infant diet quality score (p = 0.04). Conclusion: This study highlights the positive impact of health care provision by Indigenous midwives and confirms that higher maternal social advantage has a positive impact on child nutrition.

Maternal and newborn health profile in a first nations community in Canada.

OBJECTIVES: We sought to characterize maternal health profiles and birth outcomes among First Nations people living in Southern Ontario. METHODS: We performed a retrospective chart review of all 453 women from the Six Nations Reserve, Ontario, who were pregnant between 2005 and 2010. Maternal health behaviours, past medical history, physical measurements, birth outcomes, and newborn characteristics were abstracted. Key maternal and newborn characteristics were compared with those of a cohort of non-First Nations women recruited from nearby Hamilton, Ontario. RESULTS: The average age of women in the study cohort was 25.1 ± 6.2 (mean ± SD) years, and 75.8% were multiparous. The mean pre-pregnancy BMI was 28.3 ± 6.6 kg/m(2), and the average weight gain in pregnancy was 14.9 ± 8.3 kg. Mean weight gain during pregnancy was inversely associated with pre-pregnancy BMI, and 57.1% of women gained more than the recommended weight. The prevalence of type 2 diabetes or gestational diabetes was 4.7%, hypertension was present before or during pregnancy in 5.6%, and 35% used tobacco during pregnancy. The mean gestational age at delivery was 39.5 ± 1.7 weeks and the mean crude birth weight was 3619 ± 557 g. The main determinants of newborn weight included sex of the newborn, pre-pregnancy BMI, and weight gain during pregnancy. Compared with a contemporary cohort of 622 non-First Nations mothers and newborns, First Nations mothers were, on average, younger (25.1 vs. 32.1 years; P < 0.001), had a higher mean pre-pregnancy BMI (28.3 vs. 26.8 kg/m(2); P < 0.001), and were more likely to use tobacco during pregnancy (35.0% vs. 14.4%; P < 0.001). First Nations newborns had significantly higher mean birth weight (+176 grams) and length (+2.3 cm) than non-First Nations newborns. CONCLUSION: First Nations mothers from the Six Nations Reserve tended to have a high pre-pregnancy BMI, tended to gain more than the recommended weight during pregnancy, and commonly used tobacco during pregnancy. Programs to prevent overweight/obesity and excess weight gain during pregnancy and to minimize smoking are required among women of child-bearing age in this community.

Objectifs : Nous avons cherché à caractériser les profils de santé maternelle et les issues de l'accouchement chez les peuples des Premières Nations vivant dans le sud de l'Ontario. Méthodes : Nous avons mené une analyse rétrospective des dossiers des 453 femmes de la Six Nations Reserve, en Ontario, qui étaient enceintes entre 2005 et 2010. Les comportements de santé maternelle, les antécédents médicaux, les mesures physiques, les issues de l'accouchement et les caractéristiques néonatales ont fait l'objet d'un résumé. Les caractéristiques maternelles et néonatales clés ont été comparées à celles d'une cohorte de femmes n'étant pas issues des Premières Nations qui ont été recrutées tout près, à Hamilton, en Ontario. Résultats : L'âge moyen des femmes de la cohorte d'étude était de 25,1 ± 6,2 ans (moyenne ± σ) et 75,8 % d'entre elles étaient multipares. L'IMC prégrossesse moyen était 28,3 ± 6,6 kg/m2 et le gain pondéral moyen pendant la grossesse était de 14,9 ± 8,3 kg. Le gain pondéral moyen pendant la grossesse était inversement proportionnel à l'IMC prégrossesse et 57,1 % des femmes ont dépassé le gain pondéral recommandé. La prévalence du diabète de type 2 ou du diabète gestationnel était de 4,7 %, une hypertension était présente avant ou pendant la grossesse chez 5,6 % des participantes et 35 % d'entre elles ont consommé du tabac pendant la grossesse. L'âge gestationnel moyen au moment de l'accouchement était de 39,5 ± 1,7 semaines et le poids de naissance brut moyen était de 3 619 ± 557 g. Parmi les principaux déterminants du poids néonatal, on trouvait le sexe du nouveau-né, l'IMC prégrossesse et le gain pondéral pendant la grossesse. Par comparaison avec une cohorte contemporaine de 622 mères et nouveau-nés n'étant pas issus des Premières Nations, les mères issues de ces dernières étaient, en moyenne, plus jeunes (25,1 vs 32,1 ans; P < 0,001), présentaient un IMC prégrossesse moyen plus élevé (28,3 vs 26,8 kg/m2; P < 0,001) et étaient plus susceptibles de consommer du tabac pendant la grossesse (35,0 % vs 14,4 %; P < 0,001). Les nouveau-nés issus des Premières Nations présentaient une longueur (+2,3 cm) et un poids de naissance (+176 grammes) moyens considérablement plus élevés, par comparaison avec les nouveau-nés n'étant pas issus des Premières Nations. Conclusion : Les mères issues des Premières Nations de la Six Nations Reserve ont eu tendance à présenter un IMC prégrossesse élevé et à dépasser le gain pondéral recommandé pendant la grossesse, en plus de consommer couramment du tabac pendant cette période. Des programmes qui visent la prévention de la surcharge pondérale / de l'obésité et du gain pondéral excédentaire pendant la grossesse, et qui visent à minimiser le tabagisme s'avèrent requis pour les femmes en âge de procréer de cette communauté.

A School-Based Health Center-University Nursing Partnership: How We Filled in the GAPS.

Young adolescents, age 10-15 years, have increasing psychosocial and biomedical health care needs, yet are some of the lowest users of conventional health services. In eastern North Carolina, school-based health centers (SBHCs) provide primary health care to thousands of school-age children in the most rural, medically underserved areas. SBHCs receive reimbursement from local, state, and private funding sources and their viability depends on the demonstration of outcomes. Using the Guidelines for Adolescent Preventive Services (GAPS) assessment tool, an SBHC-university nursing partnership evaluated the use of preventive health services by fifth and sixth grade students (n = 690). Findings suggest that the vast majority of early adolescents needed a referral for a physical exam, nutrition, mental health, or health education services. This article describes key components for a successful SBHC-university nursing partnership that can evaluate and improve existing school health programs.
