RESUMO

Comprehensive school-based nutrition interventions offer a promising strategy to support healthy eating for First Nations children. A targeted strategic review was performed to identify nutrition interventions in 514 First Nation-operated schools across Canada through their websites. Directed content analysis was used to describe if interventions used 1 or more of the 4 components of the Comprehensive School Health (CSH) framework. Sixty schools had interventions. Nearly all (n = 56, 93%) schools offered breakfast, snack, and (or) lunch programs (social and physical environment). About one-third provided opportunities for students to learn about traditional healthy Indigenous foods and food procurement methods (n = 18, 30%) (teaching and learning) or facilitated connections between the school and students' families or the community (n = 16, 27%) (partnerships and services). Few schools (n = 10, 17%) had a nutrition policy outlining permitted foods (school policy). Less than 1% (n = 3) of interventions included all 4 CSH components. Results suggest that most First Nation-operated schools provide children with food, but few have nutrition interventions that include multiple CSH components. First Nation-operated schools may require additional financial and (or) logistical support to implement comprehensive school-based nutrition interventions, which have greater potential to support long-term health outcomes for children than single approaches.

RESUMO

Purpose: To describe (i) nutrition policies in childcare centres, (ii) the resources and processes used to enable policy implementation, and (iii) the association between policy implementation and childcare centres' or administrators' characteristics.Methods: Between October 2018 and June 2019 a web-based survey that addressed nutrition policy, policy implementation, and sociodemographic characteristics was sent to eligible childcare programs (centre-based and provided meals) in the Edmonton (Alberta) metropolitan region. The survey was pretested and pilot tested. Statistical tests examined the relationship between policy implementation with centres' and administrators' characteristics.Results: Of 312 childcare centres that received the survey invitation, 43 completed it. The majority of centres had a nutrition policy in place (94%). On average, centres had about 9 of the 17 implementation resources and processes assessed. Most often administrators reported actively encouraging the implementation of the nutrition policy (n = 35; 87%) and least often writing evaluation reports of the implementation of the nutrition policy (n = 9; 22%). Administrator's education level was associated with implementation total score (p = 0.009; Kruskal-Wallis).Conclusion: Most childcare centres had a nutrition policy in place, but many lacked resources and processes to enable policy implementation. Additional support is required to improve nutrition policy development and implementation.

RESUMO

The objective was to conduct an environmental scan of existing Canadian childcare resources targeting nutrition, physical activity, sedentary behaviour, and/or sleep. A comprehensive search plan was conducted that involved four search strategies: (1) grey literature databases, (2) customized Google search engines, (3) targeted websites, and (4) consultation with content experts. A resource (i.e., information, materials) must have been created by government or an organization/agency within Canada, available in English, intended for childcare educators or directors working with children ≤ 5 years of age, and focused on targeting improvements in nutrition, physical activity, sedentary behaviour, and/or sleep. The quality of each included resource was assessed using a modified version of the Authority, Accuracy, Coverage, Objectivity, Date, Significance checklist. A total of 192 eligible resources were included. Most resources targeted only nutrition (n = 101) or physical activity (n = 60), and few resources targeted only sedentary behaviour (n = 2) or sleep (n = 1). The remaining 28 resources targeted more than one health behaviour. The 4 most common topics of resources were menu/meal planning (n = 55), healthy nutrition practices/environment (n = 37), physical activities/games (n = 33), and nutrition/food literacy (n = 20). Only 52 included resources cited evidence. One-third of the included resources (n = 64) were rated as high quality, including 55 that received a point for the significance criterion. Therefore, numerous high quality Canadian childcare resources exist for nutrition and physical activity. Future resource development is needed for sedentary behaviour and sleep. Findings can assist future intervention work and the database of resources can be utilized by relevant stakeholders to support other childcare initiatives. Supplementary Information: The online version contains supplementary material available at 10.1007/s10643-021-01266-2.

RESUMO

BACKGROUND: Indigenous children in Canada (First Nations, Inuit, and Métis) are disproportionately affected by nutrition-related chronic diseases such as obesity and diabetes. Comprehensive school-based nutrition interventions offer a promising strategy for improving children's access to healthy foods and sustaining positive eating behaviors. However, little is known about school-based nutrition interventions for Indigenous children. The objectives of this scoping review were to identify school-based nutrition interventions for Indigenous children in Canada and describe their components. METHODS: The scoping review consisted of searches in seven peer-reviewed databases and a general web search for grey literature. Eligibility criteria were applied by two reviewers, and data were extracted and charted by one reviewer using components of the comprehensive school health approach (social and physical environment, teaching and learning, policy, partnerships and services) and additional components with relevance to Indigenous interventions (cultural content, Indigenous control and ownership, funding source, evaluation). Numerical and descriptive summaries were used to present findings. RESULTS: Thirty-four unique interventions met the inclusion criteria. The majority (97%) of interventions targeted the social and physical environment, most often by offering food programs. Over half of interventions also incorporated teaching and learning (56%) and partnerships and services (59%), but fewer included a policy component (38%). Many interventions included a cultural component (56%) and most (62%) were owned and controlled by Indigenous communities (62%). Finally, over half of interventions disclosed their source(s) of funding (59%), but less than half (41%) included an evaluation component. CONCLUSIONS: The review suggests that school-based interventions for Indigenous children can be more comprehensive by incorporating culturally relevant nutrition education and professional development opportunities for teachers, written school nutrition policies, and activities that actively engage families and community members. The continued focus on Indigenous control and ownership and incorporation of content specific to individual communities may enhance cultural relevancy and sustainability of interventions. Furthermore, there is a need to increase intervention evaluation and the sharing of resources related to funding. These recommendations may be used by communities, as well as by researchers and professionals working with communities, in developing comprehensive school-based nutrition interventions to improve the eating behaviors of Indigenous children.

RESUMO

Purpose: A school nutrition policy (SNP) is one promising school-based health promotion strategy to improve the food environments of First Nations children. The aim of this study was to explore First Nations parents' perceptions of a SNP. Methods: A process evaluation of policy implementation was conducted using a mixed-methods design. Parents (n = 83) completed a 19-question survey to capture their perceptions of the policy. Survey responses informed questions in an 11-question semi-structured interview guide. Transcripts from interviews with parents (n = 10) were analyzed using content analysis to identify barriers and facilitators to policy implementation. Results: Parents were supportive of the SNP and the school's food programs, which they perceived as helping to address community concerns related to nutrition. However, some parents opposed the restriction of unhealthy foods at school celebrations and fundraisers. In addition, despite being aware of the SNP, parents were unable to demonstrate an understanding of the SNP content. Finally, parents struggled to provide their children with healthy foods to bring to school due to lack of affordable and accessible food in the community. Conclusions: Although SNPs may be well-received in First Nations communities, their implementation must be supported by parent involvement and consideration of wider socioeconomic conditions.

RESUMO

PURPOSE: We compared food insecurity status, coping strategies, demographic characteristics, and self-rated health of international and domestic postsecondary students requesting emergency food hampers from a campus food bank (CFB). METHODS: We collected data from a cross-sectional convenience sample of domestic and international students who accessed the CFB at the University of Alberta. RESULTS: Food insecurity was prevalent (international students: n = 26/27 (96.2%), domestic students: n = 31/31 (100%)). Compared with their domestic peers, international students were less likely to rate their mental health negatively (14.8% vs 38.7%, P = 0.04). The primary income source was government loans (54.8%) for domestic students and research assistantships (33.3%) for international students. To cope with not having enough money for food, the majority of both student groups delayed bill payments or buying university supplies, applied for loans or bursaries, purchased food on credit, or worked more. International students were less likely to ask friends or relatives for food (48.1% vs 77.4%, P = 0.02). CONCLUSIONS: Domestic and international students mostly used similar coping strategies to address food insecurity; however, they paid for their education using different income sources. Distinct strategies for international and domestic students are required to allow more students to cover their educational and living expenses.

RESUMO

PURPOSE: The purpose of this scoping review was to determine the feasibility of conducting a systematic review of approaches for screening or assessing cognitive function that were comprehensive and that could be incorporated into clinical settings. METHODS: Using the scoping review approach developed by Arksey and O'Malley, we searched Ovid Embase 1980-, Ovid PsycINFO 1806-, Ovid Health and Psychosocial Instruments 1985-, EBSCOhost CINAHL, ISI Web of Science (Science Citation Index 1900-), Social Sciences Citation Index 1900-, Conference Proceedings Citation Index -Science 1990-, Conference Proceedings Citation Index -Social Science & Humanities 1990-, Scopus 1960-, with no language restrictions. Searches were conducted in April 2009 and updated in February 2013. Studies of adults treated with chemotherapy that included at least seven of the eight domains of cognition were included. RESULTS: Eleven studies met inclusion criteria. No screening tools suitable for inclusion in a clinic were identified. The studies reviewed varied by inclusion/exclusion criteria, design, and instruments for assessing cognitive function, and thus, there are not yet enough studies to warrant a systematic review on this topic.

RESUMO

OBJECTIVE: The objective of the present study was to gain an understanding of the organizational characteristics and processes in two child-care centres that may influence adoption of the Alberta Nutrition Guidelines for Children and Youth (ANGCY). DESIGN: In-depth qualitative case studies. Data were collected through direct observations, key informant interviews and field notes. Diffusion of Innovations theory guided the evaluation and intrinsic case analysis. SETTING: Two urban child-care centres in Edmonton, Alberta, Canada identified as exemplary early adopter cases. SUBJECTS: Ten key informants comprised of directors, junior and senior staff members participated in interviews. RESULTS: Organizational processes such as leadership, networking and knowledge brokering, health champions and organizational culture positively influenced adoption behaviour in child-care centres. A key determinant influencing organizational behaviour within both centres was the directors' strong leadership. Acceptance of and adherence to the guidelines were facilitated by organizational factors, such as degree of centralization, formalization and complexity, level of staff training and education. Knowledge brokering by directors was important for transferring and exchanging information across the centre. All child-care staff embraced their informal role as health champions as essential to supporting guideline adherence and encouraging healthy food and eating environments. CONCLUSIONS: Organizational processes and characteristics such as leadership, knowledge brokering and networking, organizational culture and health champions played an important role in the adoption of nutrition guidelines in child-care centres. The complex interplay of decision making, organization of work and specialization of roles influenced the extent to which nutrition guidelines were adopted.

RESUMO

PURPOSE: School-based interventions may increase children's preferences for vegetables and fruit (V&F). This Canadian study measured changes in Indigenous First Nations schoolchildren's V&F knowledge, preferences, and home consumption following the implementation of a gardening and V&F snack program. METHODS: At baseline, 7 months, and 18 months, children in grades 1-6 (i) listed at least 5 V&F they knew, (ii) tasted and indicated their preferences towards 9 vegetables and 8 fruit using a 6-point Likert scale, and (iii) indicated their home consumption of 17 V&F. RESULTS: At all 3 time points, 56.8% (n = 66/116) of children provided data. Children listed a greater number of V&F at 18 months (4.9 ± 0.1) than at baseline (4.5 ± 1.0) or 7 months (4.7 ± .07) (F(1.6,105.6) = 6.225, P < 0.05). Vegetable preferences became more positive between baseline (37.9 ± 9.3) and 7 months (39.9 ± 9.2), but returned to baseline levels at 18 months (37.3 ± 8.7) (F(1.6,105.8) = 4.581, P < 0.05). Fruit preferences at 18 months (42.7 ± 3.0) were greater than at baseline (41.1 ± 4.3) and at 7 months (41.9 ± 5.1) (F(1.7,113.3) = 3.409, P < 0.05). No change in V&F consumption occurred at home. CONCLUSIONS: Despite improvements in V&F knowledge and preferences, home consumption of V&F did not occur. Complementing school-based programs with home-based components may be needed to influence V&F intake of children.

RESUMO

PURPOSE: To describe the food security status, food insecurity coping strategies, characteristics, and experiences of student clients of the Campus Food Bank (CFB) at the University of Alberta in Edmonton, Alberta, Canada. METHODS: A convenience sample of 58 students completed a survey from April 2013 to April 2014. Food security status was determined using the "Adult Food Security Survey Module". RESULTS: Ninety percent of CFB student clients who participated in this study were food insecure, which included both moderately and severely food insecure groups. The most prevalent coping strategies for food insecurity included applying for a loan or bursary (86.2%), seeking employment or working more hours (84.5%), and purchasing food using a credit card (77.6%). Participants were a diverse mix of students, including graduate students (50.0%), international students (46.6%), and caregivers of children (24.1%). The most common primary sources of income were government student loans (29.3%) and research assistantships (20.7%). Most participants (82.8%) liked the food they received from the food bank. CONCLUSIONS: Food insecurity is highly prevalent among student clients of this university-based food bank. Students used a variety of coping strategies to increase their disposable income, highlighting the need for additional strategies to alleviate food insecurity among vulnerable students.

RESUMO

PURPOSE: This study describes dietary changes among university students who completed a travel study program. METHODS: Seventeen undergraduate nutrition students travelled from Edmonton to Italy for 6 weeks to take 2 courses on the Mediterranean diet. In both locations students completed a 24-h dietary recall and a Food Frequency Questionnaire to assess their Mediterranean Diet Quality Index Score (MDQIS). A MDQIS of 48 indicates perfect adherence to eating patterns of the Traditional Healthy Mediterranean Diet Pyramid (THMDP). RESULTS: While in Italy students altered their diets in positive ways (increased consumption of fish and seafood (P = 0.002), wine (P < 0.0001), and olive oil (P = 0.001)) and negative ways (increased consumption of sweets (P = 0.027), poultry (P = 0.001), and meat (P = 0.049)) relative to the THMDP. Students had a significant increase in the percentage of energy from polyunsaturated and monounsaturated fatty acids and alcohol. The MDQIS was low in Edmonton (21.9 ± 3.7) and Italy (22.9 ± 3.9). CONCLUSIONS: The overall dietary pattern of students did not adhere to the THMDP. Education about the THMDP and living in Italy for 6 weeks was insufficient to change students' dietary patterns to one characterized as traditional Mediterranean. The findings highlight the challenges of implementing dietary changes even with nutrition education and increased food access.

RESUMO

The aim of this study was to examine the barriers to following complementary feeding guidelines among Middle Eastern mothers and the cultural considerations of practitioners from an emic perspective. This is a two-phase focused ethnographic assessment of infant feeding among 22 Middle Eastern mothers in Western Canada who had healthy infants aged <1 year. Data were collected through four focus groups conducted in Arabic/Farsi, and were further complemented by comprehensive survey data collected in the second phase of study. Mothers' main criterion for choosing infant foods was whether or not foods were Halal, while food allergens were not causes for concern. Vitamin D supplements were not fed to 18/22 of infants, and mashed dates (Halawi), rice pudding (Muhallabia/Ferni) and sugared water/tea were the first complementary foods commonly consumed. Through constant comparison of qualitative data, three layers of influence emerged, which described mothers' process of infant feeding: socio-cultural, health care system and personal factors. Culture was an umbrella theme influencing all aspects of infant feeding decisions. Mothers cited health care professionals' lack of cultural considerations and lack of relevance and practicality of infant feeding guidelines as the main reasons for ignoring infant feeding recommendations. Early introduction of pre-lacteal feeds and inappropriate types of foods fed to infants among immigrant/refugee Middle Eastern mothers in Canada is cause of concern. Involving trained language interpreters in health teams and educating health care staff on cultural competency may potentially increase maternal trust in the health care system and eventually lead to increased awareness of and adherence to best practices with infant feeding recommendations.

RESUMO

In 2008, the Alberta government released the Alberta Nutrition Guidelines for Children and Youth (ANGCY) as a resource for child care facilities to translate nutrition recommendations into practical food choices. Using a multiple case study method, early adoption of the guidelines was examined in two child care centres in Alberta, Canada. Key constructs from the Diffusion of Innovations framework were used to develop an interview protocol based on the perceived characteristics of the guidelines (relative advantage, compatibility, complexity, trialability and observability) by child care providers. Analysis of the ANGCY was conducted by a trained qualitative researcher and validated by an external qualitative researcher. This entailed reviewing guideline content, layout, organisation, presentation, format, comprehensiveness and dissemination to understand whether characteristics of the guidelines affect the adoption process. Data were collected through direct observation, key informant interviews and documentation of field notes. Qualitative data were analysed using content analysis. Overall, the guidelines were perceived positively by child care providers. Child care providers found the guidelines to have a high relative advantage, be compatible with current practice, have a low level of complexity, easy to try and easy to observe changes. It is valuable to understand how child care providers perceive characteristics of guidelines as this is the first step in identifying the needs of child care providers with respect to early adoption and identifying potential educational strategies important for dissemination.

RESUMO

The Alberta Pregnancy Outcomes and Nutrition (APrON) study is an ongoing prospective cohort study that recruits pregnant women early in pregnancy and, as of 2012, is following up their infants to 3 years of age. It has currently enrolled approximately 5000 Canadians (2000 pregnant women, their offspring and many of their partners). The primary aims of the APrON study were to determine the relationships between maternal nutrient intake and status, before, during and after gestation, and (1) maternal mood; (2) birth and obstetric outcomes; and (3) infant neurodevelopment. We have collected comprehensive maternal nutrition, anthropometric, biological and mental health data at multiple points in the pregnancy and the post-partum period, as well as obstetrical, birth, health and neurodevelopmental outcomes of these pregnancies. The study continues to follow the infants through to 36 months of age. The current report describes the study design and methods, and findings of some pilot work. The APrON study is a significant resource with opportunities for collaboration.

RESUMO

BACKGROUND: Restricted repetitive behavior (RRB) is one of two behavioral domains required for the diagnosis of autism spectrum disorder (ASD). Neuroimaging is widely used to study brain alterations associated with ASD and the domain of social and communication deficits, but there has been less work regarding brain alterations linked to RRB. METHODS: We utilized neuroimaging data from the National Institute of Mental Health Data Archive to assess basal ganglia and cerebellum structure in a cohort of children and adolescents with ASD compared to typically developing (TD) controls. We evaluated regional gray matter volumes from T1-weighted anatomical scans and assessed diffusion-weighted scans to quantify white matter microstructure with free-water imaging. We also investigated the interaction of biological sex and ASD diagnosis on these measures, and their correlation with clinical scales of RRB. RESULTS: Individuals with ASD had significantly lower free-water corrected fractional anisotropy (FAT) and higher free-water (FW) in cortico-basal ganglia white matter tracts. These microstructural differences did not interact with biological sex. Moreover, both FAT and FW in basal ganglia white matter tracts significantly correlated with measures of RRB. In contrast, we found no significant difference in basal ganglia or cerebellar gray matter volumes. LIMITATIONS: The basal ganglia and cerebellar regions in this study were selected due to their hypothesized relevance to RRB. Differences between ASD and TD individuals that may occur outside the basal ganglia and cerebellum, and their potential relationship to RRB, were not evaluated. CONCLUSIONS: These new findings demonstrate that cortico-basal ganglia white matter microstructure is altered in ASD and linked to RRB. FW in cortico-basal ganglia and intra-basal ganglia white matter was more sensitive to group differences in ASD, whereas cortico-basal ganglia FAT was more closely linked to RRB. In contrast, basal ganglia and cerebellar volumes did not differ in ASD. There was no interaction between ASD diagnosis and sex-related differences in brain structure. Future diffusion imaging investigations in ASD may benefit from free-water estimation and correction in order to better understand how white matter is affected in ASD, and how such measures are linked to RRB.

RESUMO

OBJECTIVE: To examine the association between frequency of assisting with home meal preparation and fruit and vegetable preference and self-efficacy for making healthier food choices among grade 5 children in Alberta, Canada. DESIGN: A cross-sectional survey design was used. Children were asked how often they helped prepare food at home and rated their preference for twelve fruits and vegetables on a 3-point Likert-type scale. Self-efficacy was measured with six items on a 4-point Likert-type scale asking children their level of confidence in selecting and eating healthy foods at home and at school. SETTING: Schools (n =151) located in Alberta, Canada. SUBJECTS: Grade 5 students (n = 3398). RESULTS: A large majority (83-93 %) of the study children reported helping in home meal preparation at least once monthly. Higher frequency of helping prepare and cook food at home was associated with higher fruit and vegetable preference and with higher self-efficacy for selecting and eating healthy foods. CONCLUSIONS: Encouraging children to be more involved in home meal preparation could be an effective health promotion strategy. These findings suggest that the incorporation of activities teaching children how to prepare simple and healthy meals in health promotion programmes could potentially lead to improvement in dietary habits.

RESUMO

BACKGROUND: Despite growing evidence that supports the importance of 6-month exclusive breastfeeding, few Canadian mothers adhere to this, and early weaning onto solids is a common practice. This study assessed infant feeding transitions during the first 6 months postpartum and factors that predicted exclusive breastfeeding to 3 and 6 months. METHODS: This prospective cohort study was part of the Alberta Pregnancy Outcomes and Nutrition study (APrON). From an initial sample of 600 pregnant women recruited from Edmonton and Calgary, 402 mothers provided complete details at 3 months postpartum; 300 stayed on to provide information at 6 months postpartum. During pregnancy and at 3 and 6 months postpartum, data on maternal and infant socio-demographic, behavior, and feeding were collected. RESULTS: Even though there was a high rate of "ever having breastfed" (98.6%), exclusive breastfeeding rates for 3 and 6 months were 54.0% and 15.3%, respectively. After controlling for potential confounders, the study showed that mothers who held post-graduate university degrees were 3.76 times more likely to breastfeed exclusively for 6 months than those without a university degree (95% CI: 1.30-10.92; p = 0.015). In addition, mother of previous children were more likely to breastfeed exclusively for 6 months (OR: 2.21, 95% CI: 1.08-4.52; p = 0.031). Mothers who were in the highest quartile of the Iowa Infant Feeding Attitude Score were 4.29 and 5.40 times more likely to breastfeed exclusively for 3 months (95% CI: 1.31-14.08; p-trend < 0.001) and 6 months (95% CI: 2.75-10.60; P-trend < 0.001), respectively. CONCLUSIONS: The 6-month exclusive breastfeeding rate in Alberta is considerably below national and international breastfeeding recommendations. Professional advice that focuses on prenatal maternal knowledge, attitudes, and misperceptions may promote adherence to World Health Organization breastfeeding guidelines. Knowing that exclusive breastfeeding is less likely to take place among lower-educated, primiparous women may help health practitioners focus their support and education for this group.

RESUMO

PURPOSE: The association between preference for and intake of fruits and vegetables was examined among Albertan children. METHODS: Data used were collected as part of a provincial population-based survey among grade 5 children in Alberta. Intake of two fruits and five vegetables was assessed using the Harvard food frequency questionnaire, and preference for individual fruit and vegetable items was rated using a three-point Likert-type scale. Random effects models with children nested within schools were used to test for associations between fruit and vegetable preference and intake. RESULTS: A total of 3398 children aged 10 to 11 years returned completed surveys. Children who reported a greater liking for fruits and vegetables also reported significantly (p<0.001) higher intake. On average, children who liked a food a lot ate 0.5 to 2.7 more weekly servings of the food than did children who did not like the food. CONCLUSIONS: These findings suggest that focusing on interventions designed to increase taste preference may lead to increased fruit and vegetable intake among children. Introducing children to unfamiliar fruits and vegetables through taste testing may be an effective and practical health promotion approach for improving dietary habits.

RESUMO

Dietary patterns were examined in a convenience sample of 36 female University of Alberta students, all of whom had completed at least one nutrition course. Data from a validated food frequency questionnaire were used to determine if students had a dietary pattern similar to that recommended in Eating Well with Canada's Food Guide (EWCFG) or by the Traditional Healthy Mediterranean Diet Pyramid (THMDP), as measured using a Mediterranean Diet Quality Index Score. No student consumed the THMDP minimum number of portions of legumes, seeds, and nuts, of olive oil, or of whole grains. The majority did not meet the minimum EWCFG recommendations for any food group. The results suggest that nutrition education alone may be insufficient to ensure optimal dietary patterns among female university students. The methodology reported in this study is novel in assessing whether dietary patterns resemble the THMDP or the EWCFG.

RESUMO

The aim of this study was to explore from the Middle-Eastern mothers' perspective, the experience of breastfeeding and their perceptions of attributes of the health care system, community and society on their feeding decisions after migration to Canada. New immigrant mothers from the Middle East (n = 22) were recruited from community agencies in Edmonton, Canada. Qualitative data were collected through four focus groups using an ethnographic approach to guide concurrent data collection and analysis. Survey data were collected on socio-demographic characteristics via pre-tested questionnaires. All mothers, but one who was medically exempt, breastfed their infants from birth and intended to continue for at least 2 years. Through constant comparison of data, five layers of influence emerged which described mothers' process of decision making: culture/society, community, health care system, family/friends and mother-infant dyad. Religious belief was an umbrella theme that was woven throughout all discussions and it was the strongest determining factor for choosing to breastfeed. However, cultural practices promoted pre-lacteal feeding and hence, jeopardising breastfeeding exclusivity. Although contradicted in Islamic tradition, most mothers practised fasting during breastfeeding because of misbeliefs about interpretations regarding these rules. Despite high rates of breastfeeding, there is a concern of lack of breastfeeding exclusivity among Middle-Eastern settlers in Canada. To promote successful breastfeeding in Muslim migrant communities, interventions must occur at different levels of influence and should consider religious beliefs to ensure cultural acceptability. Practitioners may support exclusive breastfeeding through cultural competency, and respectfully acknowledging Islamic beliefs and cultural practices.
