    Abstract Household food insecurity is generally associated with poorer quality diets in Canada, but whether household food insecurity heightens the probability of inadequate micronutrient intakes is unknown. The objective of this research was to investigate how prevalence of micronutrient inadequacy differed by severity of household food insecurity among adults in Canada. Using the 2015 Canadian Community Health Survey Nutrition, this study included participants aged 19-64 years who completed up to two 24 h dietary recalls and provided details about household food insecurity (

    Abstract To examine the relationship between the dietary quality of Canadian children and adults and household food insecurity status. Dietary intake was assessed with one 24-h recall. Households were classified as food secure or marginally, moderately or severely food insecure based on their responses to the Household Food Security Survey Module. We applied multivariable analyses of variance to determine whether % energy from ultra-processed foods, fruit and vegetable intake, Healthy Eating Index (HEI) scores, macronutrient composition and micronutrient intakes per 1000 kcal differed by food insecurity status after accounting for income, education and region. Analyses were run separately for children 1–8 years and 9–18 years and men and women 19–64 years of age. Ten provinces in Canada. Respondents to the 2015 Canadian Community Health Survey-Nutrition, aged 1–64 years, with complete food insecurity data and non-zero energy intakes, N 15 909. Among adults and children, % energy from ultra-processed foods was strongly related to severity of food insecurity, but no significant trend was observed for fruit and vegetable intake or HEI score. Carbohydrate, total sugar, fat and saturated fat intake/1000 kcal did not differ by food insecurity status, but there was a significant negative trend in protein/1000 kcal among older children, a positive trend in Na/1000 kcal among younger children and inverse associations between food insecurity severity and several micronutrients/1000 kcal among adults and older children. With more severe household food insecurity, ultra-processed food consumption was higher, and diet quality was generally lower among both adults and children.

    Abstract Household food insecurity is independently associated with adverse health outcomes among Canadians, but its association with overweight and obesity is poorly understood partly because of limited attention to confounding. This study assessed the relationship between food insecurity status and overweight/obesity in Canada. Cross-sectional data for individuals aged 2-64 years were drawn from the 2004 and 2015 Canadian Community Health Survey-Nutrition. Overweight/obesity was defined using body mass index calculated with measured height and weight. Food insecurity status was assessed with the 18-item Household Food Security Survey Module. The relationship was examined among preschool children (

    Abstract Household food insecurity is a persistent public health issue in Canada. Analyses of dietary intake data from the 2004 Canadian Community Health Survey (CCHS) showed heightened nutritional vulnerability among adults and, to a lesser degree, children in food-insecure households. Given the rise in food prices since 2004, people in food-insecure households may now be at heightened nutritional risk. The objective of this study is to determine how nutritional vulnerability associated with household food insecurity has changed between 2004 and 2015. Dietary intake was assessed on the 2004 CCHS Nutrition (n = 35,107) and 2015 CCHS Nutrition (n = 20,487) using 24-hour recalls, with household food insecurity assessed using the Household Food Security Survey Module. The National Cancer Institute method was used to estimate usual intakes of nutrients of public health concern (calcium, magnesium, vitamin A, vitamin C, folate, zinc, potassium) for food-insecure participants, by survey year, considering children 1–8 years (yr) and 9–18 yr and male and female adults, 19–64 yr. Prevalence of nutrient inadequacy was assessed using the EAR cut-point approach. Differences in usual intake and prevalence of inadequacy between surveys were assessed using t-tests. Weighted bootstrap technique was utilised to generate variance estimates. In 2004 and 2015, 8.4% of individuals lived in moderately or severely food-insecure households. Mean usual intakes were lower and prevalence of nutrient inadequacy were higher across groups in 2015 than 2004, but not all differences were statistically significant. Differences in mean potassium and vitamin C intakes were significant in all groups; differences for folate and magnesium were significant in all groups except older children. Calcium was significantly lower in all groups except adult males, and vitamin A was significantly lower in all groups except young children. Young children had significantly lower intakes of zinc. Older children and male adults had significantly higher prevalence of inadequacy for vitamin C. Nutritional vulnerability associated with household food insecurity has worsened over time in Canada and remains an area in need of intervention.

    Abstract The only treatment for celiac disease (CD) is a strict gluten-free diet (GFD). Nutritional deficiencies are common in CD; however, how this is influenced by the presence of symptoms, duration of CD, and compliance of GFD is less clear. The objective of this study was to compare nutritional deficiencies in CD patients to non-celiac populations on a GFD. Secondary outcomes were to compare deficiencies in short-term (<2yrs) vs long-term (≥2yrs) GFD, and in those with persistent symptoms vs asymptomatic. We included patients attending the McMaster Celiac Clinic from June 2018-August 2020. GFD adherence was assessed by Celiac Dietary Adherence Test and CD serology, vitamins and trace minerals were measured in blood samples. We enrolled 221 patients: 182 CD and 39 controls. Overall, 103/182 (56.6%) of CD were following a GFD for >2 years and 69.2% (119/182) were symptomatic. The most common micronutrient deficiencies were zinc (48.3%), ferritin (16.9%), and vitamin D (33.3%). There were no differences in micronutrient deficiencies between CD and non-celiac controls, between short and long-term GFD, nor between those strictly compliant with GFD compared to those who were fairly compliant (p>0.05). This data suggests that nutrient deficiencies may be related more to GFD nutritional inadequacy rather than malabsorption.

    Abstract Objectives: The only treatment for celiac disease (CD) is a strict gluten-free diet (GFD). Nutritional deficiencies are common in CD; however, how this is influenced by the presence of symptoms, duration of CD, and compliance of GFD is less clear. The objective of this study was to compare nutritional deficiencies in patients with CD to those of nonceliac populations on a GFD. The secondary outcomes were to compare deficiencies in short- (<2 y) versus long-term (≥2 y) GFD, and in those with persistent symptoms versus asymptomatic.
    Methods: We included patients seen at the McMaster Celiac Clinic from June 2018 to August 2020. GFD adherence was assessed with the Celiac Dietary Adherence Test, and CD serology, vitamins, and trace minerals were measured in blood samples. We enrolled 221 patients, including 182 patients with CD and 39 controls.
    Results: Overall, 103 of 182 patients with CD (56.6%) were following a GFD for >2 y and 119 patients (69.2%) were symptomatic. The most common micronutrient deficiencies were zinc (48.3%), ferritin (16.9%), and vitamin D (33.3%). There were no differences in micronutrient deficiencies between patients with CD and nonceliac controls, short- and long-term GFDs, or those strictly compliant with GFD and those who were fairly compliant (P > 0.05).
    Conclusions: These data suggest that nutrient deficiencies may be related more to GFD nutritional inadequacy rather than malabsorption.

    Abstract Dietary intake data are routinely drawn upon to explore diet-health relationships. However, these data are often subject to measurement error, distorting the true relationships. Beyond measurement error, there are likely complex synergistic and sometimes antagonistic interactions between different dietary components, complicating the relationships between diet and health outcomes. Flexible models are required to capture the nuance that these complex interactions introduce. This complexity makes research on diet-health relationships an appealing candidate for the application of machine learning techniques, and in particular, neural networks. Neural networks are computational models that are able to capture highly complex, nonlinear relationships so long as sufficient data are available. While these models have been applied in many domains, the impacts of measurement error on the performance of predictive modeling has not been systematically investigated. However, dietary intake data are typically collected using self-report methods and are prone to large amounts of measurement error. In this work, we demonstrate the ways in which measurement error erodes the performance of neural networks, and illustrate the care that is required for leveraging these models in the presence of error. We demonstrate the role that sample size and replicate measurements play on model performance, indicate a motivation for the investigation of transformations to additivity, and illustrate the caution required to prevent model overfitting. While the past performance of neural networks across various domains make them an attractive candidate for examining diet-health relationships, our work demonstrates that substantial care and further methodological development are both required to observe increased predictive performance when applying these techniques, compared to more traditional statistical procedures.

    Abstract Novelty: The Canadian Food Intake Screener was developed to rapidly assess alignment of dietary intake with the Canada's Food Guide-2019 healthy food choices recommendations. Scoring is aligned with the Healthy Eating Food Index-2019 to the extent possible. Among a sample of adults, reasonable variation in screener scores was noted, mean screener scores differed between some subgroups with known differences in diet quality, and a moderate correlation between screener scores and total Healthy Eating Food Index-2019 scores based on repeat 24 h dietary recalls was observed. The Canadian Food Intake Screener has moderate construct validity for rapid assessment of overall alignment of adults' dietary intake with the Canada's Food Guide-2019 healthy food choices recommendations.
