  • Investigating infant feeding development in wild chimpanzees using stable isotopes of naturally shed hair

    Open AccessIulia Bădescu, Cassandra Curteanu et al.ARTICLEAmerican Journal of Primatology2025

    Measuring the relative contributions of milk and non‐milk foods in the diets of primate infants is difficult from observations. Stable carbon (δ 13 C) and nitrogen (δ 15 N) isotopes in hair can be used to physiologically track infant feeding through development, but few wild studies have done so, likely due to the difficulty in collecting hair non‐invasively. We assessed infant feeding at different ages in wild chimpanzees ( Pan troglodytes ) at …

  • Developmental and Sex‐Based Variation in Nest Building Among Wild Immature Chimpanzees

    Open AccessTara Khayer, Kelly J Desruelle et al.ARTICLEAmerican Journal of Primatology2025

    All great apes build nests. Nests in trees or on the ground provide apes with a safe and comfortable place to sleep and rest at night and during the day. Nest building is a necessary skill and form of tool use that individuals learn and practice early in life, but little is known about its development and about the factors affecting the expression of nest building in infancy. We studied the development of daytime nest building of 72 wild immature…

  • From policy to plate

    Open AccessAnnette Blais, Benjamin Organ et al.ARTICLECanadian Journal of Public Health2025Referências: 7

    Canada’s newly released National School Food Policy (NSFP) and its associated federal funding commitments mark significant progress toward a more coordinated school food system in Canada. However, significant gaps remain that could undermine the policy’s effectiveness and longevity. Current bilateral agreements between federal and provincial/territorial governments highlight disparities in per-student funding, raising concerns about whether the a…

    Open AccessMavra Ahmed, Alana Richardson et al.ARTICLEFrontiers in Public Health2024

    Introduction: Following the sudden closure of schools due to the pandemic in 2020, many school food program (SFP) operators lost their operating venues and had to innovate to continue distributing meals to children. Our objective was to assess the impact of the COVID-19 pandemic on the delivery, adaptability, and resiliency of school food programs across Canada by conducting a systematic rapid review. Materials and methods: Systematic literature …

  • Human milk immune factors, maternal nutritional status, and infant sex

    Open AccessBeatrice Caffe, Aaron D Blackwell et al.ARTICLEAmerican Journal of Human Biology2023

    OBJECTIVES: Breastfeeding is an energetically costly and intense form of human parental investment, providing sole-source nutrition in early infancy and bioactive components, including immune factors. Given the energetic cost of lactation, milk factors may be subject to tradeoffs, and variation in concentrations have been explored utilizing the Trivers-Willard hypothesis. As human milk immune factors are critical to developing immune system and p…

  • High levels of breastmilk feeding despite a low rate of exclusive breastfeeding for 6 months in a cohort of vulnerable women in Toronto, Canada

    Open AccessAlison Mildon, Jane Francis et al.ARTICLEMaternal and Child Nutrition2021

    Exclusive breastfeeding (EBF) for 6 months is a global public health goal, but measuring its achievement as a marker of population breastmilk feeding practices is insufficient. Additional measures are needed to understand variation in non-EBF practices and inform intervention priorities. We collected infant feeding data prospectively at seven time points to 6 months post-partum from a cohort of vulnerable women (n = 151) registered at two Canada …

  • Dietary diversity and social determinants of nutrition among late adolescent girls in rural Pakistan

    Open AccessJo-Anna B Baxter, Yaqub Wasan et al.ARTICLEMaternal and Child Nutrition2021

    The conditions in which adolescent girls mature shape their health, development and nutrition. Nutrient requirements increase to support growth during adolescence, but gaps between consumption and requirements exist in low- and middle-income countries. We aimed to identify and quantify the relationship between dietary intake and diverse social determinants of nutrition (SDN) among a subset of adolescent girls 15-18.9 years (n = 390) enrolled with…

  • Breastfeeding rates are high in a prenatal community support program targeting vulnerable women and offering enhanced postnatal lactation support

    Open AccessJane Francis, Alison Mildon et al.ARTICLEInternational Journal for Equity…2021

    This study provides initial evidence that postnatal lactation support can be delivered within a CPNP site, with high uptake by clients. While all participants initiated breastfeeding and 84% continued for 6 months, adherence to the recommended 6 months of exclusive breastfeeding was low. Further research is needed to better understand the barriers to exclusive breastfeeding and how to support this practice among vulnerable women. Study registered…

  • Vulnerable mothers' experiences breastfeeding with an enhanced community lactation support program

    Open AccessJane Francis, Alison Mildon et al.ARTICLEMaternal and Child Nutrition2020

    The Canada Prenatal Nutrition Program (CPNP) provides a variety of health and nutrition supports to vulnerable mothers and strongly promotes breastfeeding but does not have a formal framework for postnatal lactation support.

  • It makes you someone who changes with the times’

    Open AccessKristy M Hackett, Mohsen Kazemi et al.ARTICLEHealth Policy and Planning2019Referências: 28

    Mobile health (mHealth) applications have been developed for community health workers (CHW) to help simplify tasks, enhance service delivery and promote healthy behaviours. These strategies hold promise, particularly for support of pregnancy and childbirth in low-income countries (LIC), but their design and implementation must incorporate CHW clients’ perspectives to be effective and sustainable. Few studies examine how mHealth influences client …

  • Household composition and the infant fecal microbiome

    Open AccessAvery A Lane, Michelle K Mcguire et al.ARTICLEAmerican Journal of Physical…2019Citada por: 5Referências: 82

    OBJECTIVES: Establishment and development of the infant gastrointestinal microbiome (GIM) varies cross-culturally and is thought to be influenced by factors such as gestational age, birth mode, diet, and antibiotic exposure. However, there is little data as to how the composition of infants' households may play a role, particularly from a cross-cultural perspective. Here, we examined relationships between infant fecal microbiome (IFM) diversity/c…
