Abstract
Background: Vitamin D deficiency has reached pandemic levels affecting over one billion people worldwide. However, limited data is available on the prevalence and determinants of vitamin D status of Canadian Indigenous children and no study has been reported in Inuit children from Nunavik. Aim: Therefore, using data collected between 2006 and 2010, we aimed to investigate the prevalence and main determinants of insufficient serum 25-hydroxyvitamin D (s25(OH)D) concentrations in Inuit children attending childcare centres in Nunavik. Methods: This study included 245 Inuit children aged 11 to 54 months. s25(OH)D concentrations were measured by radioimmunoassay. Dietary intakes were assessed using 24-hour recalls. Usual dietary intakes were estimated using the National Cancer Institute method. We used a multiple imputation technique to replace missing values when performing regression analysis. Results: Our findings revealed that 64.5% of children had a s25(OH)D concentration < 75 nmol/L, while 78.1% did not meet the estimated average requirement (EAR) for vitamin D. Vitamin D intake and fluid milk consumption were positively associated with s25(OH)D concentrations, while negative associations were observed with children' energy intake, non-alcoholic beverage consumption, body weight, breastfeeding duration and, biological/adoptive/foster parents' educational level. Conclusion: Vitamin D inadequacy was highly prevalent and closely aligned with levels observed over the years in non-Indigenous children. Breastfed children who do not receive vitamin D supplementation, overweight and obese children, and children with inadequate milk consumption were at high risk of vitamin D insufficiency. Eating vitamin D rich foods such as fluid milk and seafood along with vitamin D supplementation when needed are recommended.

Abstract
Objective: The purpose of the study was to assess knowledge and perceptions related to carbohydrates, including sugars, among Canadian nutrition-major undergraduates compared to those enrolled in elective nutrition courses (i.e., "nutrition-elective students").Methods: Cross-sectional surveys were distributed during class time at eight Canadian universities, which included 32 questions on demographics, knowledge and perceptions of carbohydrates and sugars. Descriptive analyses were performed. Differences between groups were tested by Chi-squared statistics.Results: A total of 1207 students (60% nutrition-majors) participated in the survey (January 2016-February 2017). Internet-based sources accounted for one-third of the sources where students obtained nutrition information. About 61% of internet-bases sources were "online" or "website" with no qualifiers, and about a quarter was from social media. A higher percentage of nutrition-majors correctly answered knowledge questions of carbohydrates compared with nutrition-elective students (p < 0.01); no difference was observed for sugars-related knowledge questions. The perceptions of sugars were generally negative and did not differ between groups.Conclusions: Several knowledge gaps and common perceptions on topics related to carbohydrates and sugars were identified; nutrition-major students performed better than nutrition-elective students on carbohydrate knowledge questions, but not sugars. These results highlight the importance of identifying methods to help students bridge knowledge gaps and develop skills to critically evaluate nutrition information from various resources and challenge personal biases.

Abstract
In this study, we report the temporal trends of persistent organic pollutants (POPs) in 181 preschool Inuit children from Nunavik and the influence of confounding factors on blood contaminant levels. From 2006 to 2010, no significant trends were detected in Σpolychlorinated biphenyls (ΣPCBs), Σorganochlorine pesticides (ΣOPs), Σtoxaphene, and Σper- and polyfluoroalkyl substances (ΣPFASs). On the contrary, significant downward trends ranging from 9.3% to 14.3% per year were found for polybrominated diphenyl ethers (PBDEs). Breastfeeding was significantly associated with increased levels of POPs. Age was positively and significantly related to ΣPCBs, ΣOPs and Σtoxaphene. Compared with girls, boys had significantly higher concentrations of ΣPBDEs, but lower concentrations of ΣPFASs. Weight-for-height or body mass index z-scores were negatively and significantly related to ΣPCBs and ΣOPs. Passive smoking was positively and significantly associated with ΣOPs and Σtoxaphene. In conclusion, continued efforts to reduce contaminant exposure are needed to protect children's health and development.

Abstract
OBJECTIVES To assess dietary fatty acid intakes and to examine the relationship between dietary sources of n-3 and n-6 PUFA and red-blood-cell (RBC) n-3 and n-6 PUFA composition. DESIGN A cross-sectional study. Dietary intakes were assessed with a 24 h dietary recall. A second recall was performed for 44 % of the children. Usual dietary intakes were estimated with the Software for Intake Distribution Estimation (SIDE). The fatty acid composition was measured in RBC membranes. Multivariate linear regression analyses were performed to explain RBC n-3 and n-6 PUFA concentrations. SETTING Child-care centres in Nunavik, northern Québec, Canada. SUBJECTS One hundred and sixty-seven Inuit children aged 11-53 months. RESULTS A high proportion of the participants had inadequate n-3 and n-6 PUFA intakes (47·9 % and 93·5 %, respectively). Breast-feeding status and consumption of traditional food during the first 24 h dietary recall were significantly associated with RBC n-3 PUFA levels. Older children also tended to have higher RBC n-3 PUFA levels (P = 0·0528), whereas sex, infant formula status and n-3 PUFA dietary intakes were not associated with RBC n-3 PUFA concentrations. RBC n-6 PUFA concentrations were positively associated with breast-feeding status and n-6 PUFA dietary intakes, whereas age, sex and infant formula status were not. CONCLUSIONS The present findings highlight the fact that Inuit pre-school children are not consuming enough n-3 and n-6 PUFA for optimum health. These observations call for actions to increase traditional food intake among Inuit children and to help them and their parents make healthier store-bought food choices.

Abstract
High blood lead levels (BLLs) can be found in Inuit from Nunavik. At the same time, various nutrients such as calcium could lower lead absorption and toxicity. We examined the effect of dietary calcium intakes on BLLs in 245 preschool Inuit children attending childcare centres in Nunavik. Calcium intake was assessed with one 24-h dietary recall and BLLs were determined by inductively coupled plasma mass spectrometry in whole blood samples. Multiple imputation was performed to deal with missing data. Median blood lead concentration was 0.08 μmol/L. A high proportion of children did not meet the Estimated Average Requirement for vitamin D intake (73 %) and, to a lower extent, for calcium (20 %). Calcium intake was negatively associated with BLLs (p = 0.0001) while child's age and energy intake were positively associated with BLLs (p = 0.015 and p = 0.024, respectively). Consuming traditional foods rich in calcium as well as milk and alternatives may protect against lead exposure.

Abstract
Some evidence suggests that various diet components and nutrients, including vegetables, fruit and food-derived antioxidants, could mitigate contaminant exposure and/or adverse health effects of contaminants. To examine the effect of the consumption of tomato products on blood mercury levels in Inuit preschool children, 155 Inuit children (25.0±9.1months) were recruited from 2006-2008 in Nunavik childcare centers (northern Québec, Canada). Food frequency questionnaires were completed at home and at the childcare center, and total blood mercury concentration was measured by inductively coupled plasma-mass spectrometry. Multivariate regression analysis was performed after multiple imputation. The median blood concentration of mercury was 9.5nmol/L. Age, duration of breastfeeding, annual consumption frequency of seal meat, and monthly consumption frequency of tomato products were significant predictors of blood mercury levels, whereas annual consumption frequencies of beluga muktuk, walrus, Arctic char, and caribou meat were not. Each time a participant consumed tomato products during the month before the interview was associated with a 4.6% lower blood mercury level (p=0.0005). All other significant predictors in the model were positively associated with blood mercury levels. Further studies should explore interactions between consumption of healthy store-bought foods available in Arctic regions and contaminant exposure.

Abstract
OBJECTIVES To describe traditional food (TF) consumption and to evaluate its impact on nutrient intakes of preschool Inuit children from Nunavik. DESIGN A cross-sectional study. METHODS Dietary intakes of children were assessed with a single 24-hour recall (n=217). TF consumption at home and at the childcare centres was compared. Differences in children's nutrient intakes when consuming or not consuming at least 1 TF item were examined using ANCOVA. RESULTS A total of 245 children attending childcare centres in 10 communities of Nunavik were recruited between 2006 and 2010. The children's mean age was 25.0±9.6 months (11-54 months). Thirty-six percent of children had consumed at least 1 TF item on the day of the recall. TF contributed to 2.6% of total energy intake. Caribou and Arctic char were the most reported TF species. Land animals and fish/shellfish were the main contributors to energy intake from TF (38 and 33%, respectively). In spite of a low TF intake, children who consumed TF had significantly (p<0.05) higher intakes of protein, omega-3 fatty acids, iron, phosphorus, zinc, copper, selenium, niacin, pantothenic acid, riboflavin, and vitamin B12, and lower intakes of energy and carbohydrate compared with non-consumers. There was no significant difference in any of the socio-economic variables between children who consumed TF and those who did not. CONCLUSION Although TF was not eaten much, it contributed significantly to the nutrient intakes of children. Consumption of TF should be encouraged as it provides many nutritional, economic, and sociocultural benefits.

Abstract
Arctic populations are exposed to substantial levels of environmental contaminants that can negatively affect children's health and development. Moreover, emerging contaminants have never been assessed in Inuit children. In this study, we document the biological exposure to toxic metals and legacy and emerging persistent organic pollutants (POPs) of 155 Inuit children (mean age 25.2 months) attending childcare centers in Nunavik. Blood samples were analyzed to determine concentrations of mercury, lead, polychlorinated biphenyls (PCBs), pesticides, brominated flame retardants [e.g., polybrominated diphenyl ethers (PBDEs)] and perfluoroalkyl and polyfluoroalkyl substances [PFASs; e.g. perfluorooctanesulfonate (PFOS) and perfluorooctane (PFOA)]. Lead [geometric mean (GM) 0.08 μmol/L], PCB-153 (GM 22.2 ng/g of lipid), BDE-47 (GM 184 ng/g of lipid), PFOS (GM 3369 ng/L), and PFOA (GM 1617 ng/L) were detected in all samples. Mercury (GM 9.8 nmol/L) was detected in nearly all blood samples (97%). Levels of metals and legacy POPs are consistent with the decreasing trend observed in Nunavik and in the Arctic. PBDE levels were higher than those observed in many children and adolescents around the world but lower than those reported in some U.S. cities. PFOS were present in lower concentrations than in Nunavimmiut adults. There is a clear need for continued biomonitoring of blood contaminant levels in this population, particularly for PBDEs and PFASs.

Abstract
UNLABELLED To our knowledge, the impact of socioeconomic and health related factors on the iron status of adolescent girls has never been studied in Benin. OBJECTIVE These factors were studied in 180 girls aged 12 to 17 years living in two boarding schools from South Benin. METHODS Iron deficiency (ID) was defined as either serum ferritin (SF) < 20 microg/L or SF between 20-50 microg/L plus two abnormal values in the three following parameters: serum iron < 11 micromol/L, total iron binding capacity > 73 micromol/L or transferrin saturation < 20%. Socioeconomic and health related factors were obtained from each participant by mean of an interview using a standardized and pre-tested questionnaire. RESULTS Almost half the participants reported some health problems in the last four months before the study, whereas more than 75% auto-medicated before going to the hospital. The majority of the girls believed themselves to be in good health, although only 16% could define the term 'anemia'. Multivariate regression analysis indicated that girls whose mother was a manual worker (P = .002), who came from a larger family (P = .0001), and who auto-medicated (P = .014), had a lower hemoglobin level, whereas girls who had started their menstruation (P = .008) had a lower SF level. In a logistic regression analysis, girls from a large family size and whose mother was a manual worker showed a higher risk of IDA (OR = 3.5; 95% CI = 1.1-2.5; P = .04; OR = 3.0; 95% CI = 1.2-2.2; P = .04 respectively). CONCLUSION The findings indicate that iron deficiency is related to the occupation of the mother, family size, auto-medication, and menstruation.

Abstract
Iron deficiency (ID) is the most prevalent worldwide nutritional deficiency. Groups at risk of developing ID anemia are infants and pregnant women, even in industrialized countries. Our goal in this study was to evaluate the long-term consequences of maternal ID on the offspring's fatty acid and eicosanoid metabolism, behavior, and spatial memory. Female guinea pigs consumed iron-sufficient (IS) and -deficient (ID) diets for 14 d before mating and throughout pregnancy and lactation. Dietary iron restriction resulted in ID in pregnant females. On postnatal d 9, all offspring (ID and IS) were weaned to the IS diet and at 42 d, all offspring were iron replete. Locomotion was tested in pups on postnatal d 24 and 40 and spatial memory from d 25 to 40. Pups from the ID group were significantly more active in the open field at both times of testing, whereas spatial memory, tested in a Morris water maze, was comparable in both groups. On postnatal d 42, liver, RBC, and brain fatty acid composition were measured. Dihomogammalinolenic [20:3(n-6)], docosapentaenoic [22:5(n-3)], and docosahexaenoic [22:6(n-3)] acid contents were significantly higher in brain phospholipids of offspring born to ID dams. Prostaglandin E(2) and F(2alpha) concentrations were also significantly higher in brains of offspring born to ID dams. This demonstrates that moderate ID during gestation and lactation results in alterations of brain fatty acid and eicosanoid metabolism and perturbation in behavior in adult offspring.

Abstract
BACKGROUND To our knowledge, the impact of a nutrition education program combined with an increase in bioavailable dietary iron to treat iron-deficiency anemia has never been studied in adolescent girls. OBJECTIVE To evaluate the impact of an intensive dietary program for the treatment of iron-deficiency anemia in 34 intervention and 34 control boarding-school girls aged 12 to 17 years from Benin. METHODS A quasi-experimental design consisting of 4 weeks of nutrition education combined with an increase in the content and bioavailability of dietary iron for 22 weeks was implemented in the intervention school, but not in the control school. Data were obtained from both groups from a nutrition knowledge questionnaire, 24-hour dietary recalls, anthropometric measurements, measurement of iron status indices, and screening for malarial and intestinal parasitic infections. RESULTS Nutrition knowledge scores and mean intakes of nutrients, including dietary iron, absorbable iron, and vitamin C, were significantly higher in the intervention group (p < .05) than in the control group after 26 weeks. Mean hemoglobin and serum ferritin values were also significantly higher in the intervention group than in the control group (122 vs. 112 g/L [p = .0002] and 32 vs. 19 microg/L [p = .04], respectively), whereas the prevalence of anemia (32% vs. 85% [p = .005] and iron-deficiency anemia (26% vs. 56% [p = .04]) was significantly lower in the intervention group than in the control group. No significant differences between the groups were observed in intestinal parasitic infections or malaria status postintervention. CONCLUSIONS A multidietary strategy aiming to improve available dietary iron can reduce iron-deficiency anemia in adolescent girls.

Abstract
A 26-week nutrition intervention, including 4 weeks of nutrition education, combined with an increase in the content and bioavailability of dietary iron for 22 weeks was carried out in 34 intervention and 34 control adolescent girls suffering from mild iron deficiency anemia (IDA). In post-intervention, hemoglobin and serum ferritin were significantly higher in the intervention group, whereas the incidence of IDA was significantly lower in the intervention group compared to the control group. Nutrition knowledge scores were significantly higher in intervention girls compared to control girls. Dietary changes to improve available dietary iron can reduce iron deficiency anemia.

Abstract
Intestinal parasitic infections (IPI), especially helminths, represent a major public health problem that increase iron deficiency anaemia in developing countries. This study investigated the prevalence, risk factors and nutritional consequences of IPIs in 180 adolescent girls aged 12-17 years living in two boarding schools in southern Benin. Data were collected using a structured questionnaire and laboratory analysis of blood and faecal samples. The relationships between socioeconomic indicators, IPIs and iron status were analysed using logistic regression analysis. Fifty percent of the subjects were infected with at least one IPI: 2% with helminths, 41% with protozoa and 7% with two or more intestinal parasites. Adolescent girls from a large family and those whose mothers were manual workers showed a higher risk of intestinal parasitism (odds ratio (OR)=3.5, 95% CI 2.5-5.2 (P=0.02) and OR=2.4, 95% CI 2.0-3.0 (P=0.03), respectively). Likewise, drinking untreated water was also a high risk factor for infection (OR=2.3, 95% CI 1.5-2.4; P=0.03). No significant association was observed between IPIs and iron deficiency or iron deficiency anaemia, which can be explained by the low wormload observed. These findings reinforce the need to involve mothers in health initiatives to control intestinal parasitism in Benin.

Abstract
The factors that influence the actual initiation and duration of breastfeeding were studied among low-income women followed by the Canada Prenatal Nutrition Program (CPNP). A group of 196 pregnant women were selected at random from a sample of 6223 pregnant women who registered with the CPNP. Two 24-hour recalls and information regarding lifestyle habits, peer support, and infant-feeding practices were obtained between 26 and 34 weeks of gestation and 21 days and 6 months after birth. Women who received a university education (completed or not completed) versus women with < or = high school education (odds ratio [OR], 8.40; 95% confidence interval [CI], 1.02-69.50), women born outside Canada (OR,8.81; 95% CI, 3.34-23.19), and women of low birth weight infants (OR, 0.39; 95% CI, 0.16-0.96) were more likely to initiate breastfeeding. Late introduction of solid foods (P = .004), nonsmoking (P = .005), multiparity (P = .012), and a higher level of education (P = .049) were positively associated with the duration of breastfeeding among initiators. Understanding factors associated with initiation and duration of breastfeeding among low-income women is critical to better target breastfeeding promotion.

Abstract
In the last 30 years, the prevalence of low dietary iron intake has increased, partly because North Americans have been encouraged to choose lower fat foods, including leaner meats. As a result, there has been a decrease in red meat consumption. The objective of this study was to estimate absorbable iron intakes of a representative sample of the Quebec adult population and to compare these results with the new North American recommendations for iron. Dietary intakes were obtained by 24-hour recall and absorbable iron intakes were estimated using Monsen & coworker's model. While 18.9 % and 2.5% of women and men respectively had an iron intake below the estimated average requirement (EAR), 66.2 % and 25.6% had an estimated available iron intake below the recommended level for absorbed iron. Beef consumption had the strongest association with estimated absorbable iron, followed by vegetables. Subjects with a high education level consumed significantly less meat, beef and heme iron than subjects whose education level was low or moderate. These results indicate that there is a need for improving iron intake in the Quebec adult population.

Abstract
OBJECTIVE To study the relationship between maternal diet and infant anthropometric measurements in 56 women, aged 28 +/- 5.1 years, with singleton pregnancies. STUDY DESIGN The overall quality of the diet (three 24-hour recalls), including supplementation, was evaluated at 34 +/- 1.3 weeks using a total mean adequacy ratio (TMAR) of 12 nutrients. Specific interviewing techniques were used to minimize social desirability bias. Anthropometric measurements of both parents and maternal lifestyle practices were also obtained. Infant weight, crown-heel length and head circumference were measured 14.6 +/- 4.4 days after birth. RESULTS Stepwise multiple regression analysis revealed that maternal diet quality (TMAR) was significantly related to infant weight (r = .039, P = .036) and crown-heel length (r = .071, P = .007). Other significant predictors included gestational age, maternal height, sex, smoking and physical activity. CONCLUSION Maternal diet was positively associated with infant weight and crown-heel length.
