There are knowledge gaps in our understanding of the development of chronic disease risks in children, especially with regard to the risk differentials experienced by immigrants and refugees. The Healthy Immigrant Children study employed a mixed-methods cross-sectional study design to characterize the health and nutritional status of 300 immigrant and refugee children aged 3-13 years who had been in Canada for less than 5 years. Quantitative data regarding socioeconomic status, food security, physical activity, diet, and bone and body composition and anthropometric measurements were collected. Qualitative data regarding their experiences with accessing health care and their family lifestyle habits were gathered through in-depth interviews with the parents of newcomer children. Many newcomers spoke about their struggles to attain their desired standard of living. Regarding health outcomes, significantly more refugees (23%) had stunted growth when compared with immigrants (5%). Older children, those with better-educated parents, and those who consumed a poorer-quality diet were at a higher risk of being overweight or obese. Sixty percent of refugees and 42% of immigrants had high blood cholesterol. Significant health concerns for refugee children include stunting and high blood cholesterol levels, and emerging trends indicate that older immigrant children from privileged backgrounds in low-income countries may be more at risk of overweight and obesity. A variety of pathways related to their families' conceptualization of life in Canada and the social structures that limit progress to meeting their goals likely influence the development of health inequity among refugee and immigrant children. Public health initiatives should address these health inequities among newcomer families.

Food insecurity is a significant public health problem for Indigenous peoples in Canada. A comprehensive literature review is needed to organize the evidence according to the four pillars of food security (i.e., availability, access, utilization, and stability) and identify gaps in the published literature on this topic. Therefore, this scoping review aims to summarize the published research discussing any of the four pillars of food security among Indigenous peoples in Canada. A literature search of the databases: Ovid Medline, EMBASE, Web of Science (Web of Knowledge), and CINAHL as well as Indigenous Studies Portal (up to June 19, 2021) was conducted. Population-based studies of any design were included, except for review-style articles. Articles published in other languages besides English were also excluded. Of the 4687 studies identified by the database searches, 91 met our inclusion criteria. Evidence indicates that all dimensions of food security among Indigenous peoples in Canada have been impacted. Lack of availability of both traditional and market foods is highlighted among Inuit and First Nations communities. Economic disadvantages, high food prices, and lack of access to transportation are major factors affecting the accessibility pillar of food security. Major factors affecting the utilization pillar of food security are the loss of traditional knowledge and skills, lack of knowledge on market foods, low quality of market foods, and food safety issues. Climate change has affected all four pillars of food security among Indigenous peoples. These findings suggest that resolving food insecurity issues among Indigenous peoples in Canada, especially those living in remote communities, requires a culturally specific integrated approach targeting food availability, food cost, food knowledge, food safety, and food quality.

Food insecurity continues to persist among vulnerable groups in Canada, including newcomer families. This mixed-methods study uses an exploratory sequential design to characterize the food security status of newcomer families with children aged 3–13 years. Parents completed food security and 24-hour dietary recall questionnaires, and parents and service providers were interviewed to explore their food insecurity experiences. Fifty percent of participant households experienced food insecurity, while 41% of children were food insecure. More recent newcomer families, and families with parents that had completed high school or some years of postsecondary training, more commonly experienced household food insecurity, compared to families with parents without high school diplomas or those with university degrees. Food-insecure children aged 4–8 years were at higher risk of consuming a lower proportion of energy from protein, lower servings of milk products, and inadequate intakes of vitamin B12 and calcium. Participants identified changes in food buying habits due to low income, using food budgets to purchase prescription drugs and to repay transportation loans, while the school food environment impacted children’s food security. Food security initiatives targeting newcomers may benefit from building on the strengths of newcomers, including traditional dietary practices and willingness to engage in capacity-building programming.

Adequate calcium intake and supply of vitamin D during childhood play important roles in ensuring adequate bone mass gain to achieve optimal peak bone mass. The Healthy Immigrant Children study employed a mixed-method cross-sectional study design to characterize the health and nutritional status of 300 immigrant and refugee children aged 3–13 years who had been in Canada for less than 5 years. This paper presents bone mineral content and vitamin D status data along with qualitative data that deepen the understanding of newcomer bone health status. A significantly higher percentage of refugee children (72.3%) had insufficient (<50 nmol/L) or deficient (<30 nmol/L) serum vitamin D compared with immigrants (53.2%). Vitamin D deficiency was most common among ethnic minority girls. Newcomer children with higher intakes of vitamin D, younger newcomer children, and those from western Europe or the United States had higher serum vitamin D levels. Immigrants had significantly higher mean total body bone mineral content compared with refugees. Total body fat, serum vitamin D, calcium intake, height, height by calcium intake, total body fat by calcium intake, and total body fat by height predicted total body bone mineral content levels. Vitamin D deficiency among newcomer children may be related to lack of knowledge regarding children’s vitamin D requirements in the Canadian environment, dietary habits established in country of origin, low income that limits healthy dietary choices, and lifestyle habits that limit exposure to sunlight. Results suggest a need to screen newcomer children and pregnant women for vitamin D deficiency and support early intervention.
