RESUMO
BACKGROUND: Chronic stress is an important risk factor in the development of obesity. While research suggests chronic stress is linked to excess weight gain in children, the biological or behavioral mechanisms are poorly understood. OBJECTIVE: The objectives of the Family Stress Study are to examine behavioral and biological pathways through which chronic stress exposure (including stress from COVID-19) may be associated with adiposity in young children, and to determine if factors such as child sex, caregiver-child relationship quality, caregiver education, and caregiver self-regulation moderate the association between chronic stress and child adiposity. METHODS: The Family Stress Study is a prospective cohort study of families recruited from 2 Canadian sites: the University of Guelph in Guelph, Ontario, and McMaster University in Hamilton, Ontario. Participants will be observed for 2 years and were eligible to participate if they had at least one child (aged 2-6 years) and no plans to move from the area within the next 3 years. Study questionnaires and measures were completed remotely at baseline and will be assessed using the same methods at 1- and 2-year follow-ups. At each time point, caregivers measure and report their child's height, weight, and waist circumference, collect a hair sample for cortisol analysis, and fit their child with an activity monitor to assess the child's physical activity and sleep. Caregivers also complete a web-based health and behaviors survey with questions about family demographics, family stress, their own weight-related behaviors, and their child's mental health, as well as a 1-day dietary assessment for their child. RESULTS: Enrollment for this study was completed in December 2021. The final second-year follow-up was completed in April 2024. This study's sample includes 359 families (359 children, 359 female caregivers, and 179 male caregivers). The children's mean (SD) age is 3.9 years (1.2 years) and 51% (n=182) are female. Approximately 74% (n=263) of children and 80% (n=431) of caregivers identify as White. Approximately 34% (n=184) of caregivers have a college diploma or less and nearly 93% (n=499) are married or cohabiting with a partner. Nearly half (n=172, 47%) of the families have an annual household income ≥CAD $100,000 (an average exchange rate of 1 CAD=0.737626 USD applies). Data cleaning and analysis are ongoing as of manuscript publication. CONCLUSIONS: Despite public health restrictions from COVID-19, the Family Stress Study was successful in recruiting and using remote data collection to successfully engage families in this study. The results from this study will help identify the direction and relative contributions of the biological and behavioral pathways linking chronic stress and adiposity. These findings will aid in the development of effective interventions designed to modify these pathways and reduce obesity risk in children.

Canadian movement guidelines focused on physical activity (PA), sleep, and screen time support childhood development and reduce the risk of chronic disease. Accelerometers are often used to capture these behaviors; however, they are limited in their ability to record daytime sleep due to potential misclassification. OBJECTIVES: The objectives of this study were to 1) determine the prevalence of children enrolled in the Guelph Family Health Study who met the guidelines and to 2) compare the impact of different sleep measurement methods. DESIGN/METHODS: Toddlers (1.5-<3â¯years; nâ¯=â¯128; valid data for all movement behaviors, nâ¯=â¯70), preschoolers (3-<5â¯years; nâ¯=â¯143; valid data for all movement behaviors, nâ¯=â¯104), and school-aged (5-<6â¯years; nâ¯=â¯49; valid data for all movement behaviors, nâ¯=â¯31) children were included. Screen time and sleep habits were obtained through parental report and published normative data. PA and sleep were recorded using accelerometers (wGT3X-BT ActiGraph; right hip). RESULTS: It was found that 66â¯% of toddler, 44â¯% of preschool, and 63â¯% of school-aged children met the screen time guidelines. Further, 63â¯% of toddler, 98â¯% of preschooler, and 80â¯% of school-aged children met PA guidelines. Sleep guideline compliance ranged from 3â¯% to 83â¯% in toddler, 27â¯% to 92â¯% in preschooler, and 32â¯% to 90â¯% in school-aged children. These proportions were found to be significantly different (Cochran's Q and McNemar's tests). CONCLUSIONS: Nearly all children met PA guidelines. In contrast, less than half to two-thirds met screen time guidelines. Compliance with sleep guidelines varied substantially with measurement method, highlighting the need for standardization.

Purpose: Our understanding of the influence of sugar intake on anthropometrics among young children is limited. Most existing research is cross-sectional and has focused on sugar-sweetened beverages. The study objective was to investigate longitudinal associations between young children's total, free, and added sugar intake from all food sources at baseline with anthropometric measures at baseline and 18 months.Methods: The Guelph Family Health Study (GFHS) is an ongoing randomized controlled trial and a family-based health promotion study. Food records and anthropometric data were collected at baseline (n = 109, 55 males; 3.7 ± 1.1 y, mean ± SD) and 18 months (n = 109, 55 males; 5.1 ± 1.1 y) of the GFHS pilots. Associations between sugar intakes and anthropometrics were estimated using linear regression models with generalized estimating equations adjusted for age, sex, household income, and intervention status.Results: Total sugar intake was inversely associated with body weight at 18 months (P = 0.01). There was no effect of time on any other associations between total, free, and added sugar intakes and anthropometrics.Conclusions: Early life dietary sugar intakes may not relate to anthropometric measures in the short term. Further investigation into potential associations between dietary sugar intakes and anthropometric variables over longer time periods is warranted.
RESUMO
BACKGROUND AND AIMS: Evidence implicates ultra-processed food intake as a major contributor of excess dietary sugars. However, little research exists on the relationship between the degree of food processing and sugar intake in families with young children. We investigated associations between the degree of food processing and sugar intake (total and free sugars) in Canadian preschool-aged children and parents. METHODS: This cross-sectional study of 242 families included preschool-aged children (n = 267) and parents (n = 365) participating in the Guelph Family Health Study. Dietary intake was assessed via the web-based Automated Self-Administered 24-h Dietary Assessment Tool (ASA24-Canada-2016) and classified according to the NOVA Food Classification System including, unprocessed or minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods. Linear regression models with generalized estimating equations were used to examine associations between the energy contribution of each NOVA classification category and sugar intake (% kcal of total and free sugars). Pearson correlation coefficient estimates were used to assess dietary relationships between parents and children. RESULTS: Ultra-processed foods were the greatest source of energy (44.3%) and energy from total (8.7%) and free sugars (7.3%) in the parents' diets, and the greatest source of energy (41.3%) and energy from free sugars (7.6%) in the children's diet. Ultra-processed food intake was positively associated with sugar intake in parents (total sugars: B = 0.05, 95% CI: 0.02-0.09, p = 0.01; free sugars: B = 0.11, 95% CI: 0.08-0.15, p < 0.001) and children (total sugars: B = 0.10, 95% CI: 0.04-0.16, p = 0.001; free sugars: B = 0.16, 95% CI: 0.12-0.21, p < 0.001). Unprocessed or minimally processed food intake was negatively associated with free sugar intake in parents (B = -0.08, 95% CI: -0.12 to -0.05, p < 0.001) and children (B = -0.15, 95% CI: -0.19 to -0.10, p < 0.001). Weak correlations were found between parents and children for processed culinary ingredients and ultra-processed processed food intake (p < 0.001). CONCLUSIONS: This study highlights the associations between degree of food processing and sugar intake in parents and children, whereby ultra-processed foods were positively, and unprocessed or minimally processed foods were negatively, associated with sugar intake. These are important considerations in the development of policy and recommendations for foods to potentially promote or limit.

BACKGROUND: It is crucial to develop strategies targeted to promote healthy eating patterns in vulnerable populations, especially young children from diverse sociodemographic groups. Thus, the study objective was to investigate the associations between child age, child sex, child ethnicity, parent number of years living in Canada, annual household income, parent education and parent marital status with total, free and added sugar intakes in young children. METHODS: This cross-sectional study was a secondary analysis of data gathered in the Guelph Family Health Study. The study included 267 children (129M; 138F) from 210 families aged 1.5 to 5 years. Parents completed questionnaires for children on sociodemographic characteristics and an online 24-hour diet recall. The associations between sociodemographic characteristics and sugar intakes were determined using generalized estimating equations applied to linear regression models. RESULTS: The mean age of the children was 3.5 ± 1.2 years (mean ± std dev.). As children's age increased, there was a greater intake of free and added sugar (ß^ = 8.6, p = 0.01, 95% CI = 2.4 to 14.7 and ß^ = 6.5, p = 0.03, 95% CI = 0.8 to 12.2, respectively). Those children who identified as white had a higher total sugar intake than children of other ethnicities (ß^ = 31.0, p = 0.01, 95% CI = 7.2 to 54.7). Additionally, higher annual household income was associated with lower was free sugar intake in children (ß^ = -2.4, p = 0.02, 95% CI = -4.5 to -0.4). CONCLUSIONS: This study underscores the significant influence of multiple sociodemographic characteristics on sugar intake in young children, providing valuable insights for public health policy and nutrition interventions. Moreover, this study highlights the need for early behaviour interventions focusing on reducing sugar intake in young children, while considering sociodemographic factors.
RESUMO
BACKGROUND: Excess consumption of free sugar (FS) increases the risk of dental caries and unhealthy weight gain. However, the contribution of snacks and beverages to young children's FS intake is not well understood. The purpose of this study was to determine FS intake from snacks and beverages among preschool-aged Canadian children. METHODS: This cross-sectional study examined baseline data from 267 children 1.5 to 5 y enrolled in the Guelph Family Health Study. Dietary assessment was completed over a 24-h period using ASA24-Canada-2016 to, 1) estimate the proportion of children whose FS intake from snacks and beverages consumed exceeded 5% total energy intake (TE) and 10% TE, and 2) identify the top snack and beverage sources of FS. RESULTS: FS contributed 10.6 ± 6.9% TE (mean ± SD). 30 and 8% of children consumed ≥ 5% TE and ≥ 10% TE from snack FS, respectively. Furthermore, 17 and 7% of children consumed ≥ 5% TE and ≥ 10% TE from beverages FS, respectively. Snacks and beverages accounted for 49 ± 30.9% of FS energy. Top snack sources of FS (% children, children's %TE from FS) were bakery products (55%, 2.4%), candy and sweet condiments (21%, 3.0%), and sugar-containing beverages (20%, 4.1%). Top sugar-containing beverage sources of FS (48%, 5.3%) were 100% fruit juice (22%, 4.6%) and flavored milk (11%, 3.1%). CONCLUSIONS: Snacks and beverages contributed nearly half of FS intake among a sample of young children in Canada. Thus, long-term monitoring of snacking behavior and consumption of FS is warranted. These findings may help inform nutritional strategies and public policies to improve diet quality and FS intake in preschool-aged children. TRIAL REGISTRATION: The Clinical Trial Registry number is NCT02939261 from clinicaltrials.gov. Date of Registration: October 20, 2016.
RESUMO
Purpose: To investigate the breakfast quality of preschool-aged children through a comparison of their energy and nutrient intakes at breakfast to published benchmarks for a balanced breakfast.Methods: Dietary data were collected for 163 children aged 3-5 years enrolled in the Guelph Family Health Study using one parent-reported online 24-hour recall and analyzed for energy and nutrient intakes. Breakfast quality was assessed by tallying the frequency of participants whose nutrient and energy intakes at their breakfast meal met the recommendations for a balanced breakfast established by the International Breakfast Research Initiative (IRBI).Results: Almost all participants (98%) consumed breakfast, and most participants (82.5%) met the energy IRBI recommendation. However, the majority of participants did not meet the IRBI recommendations for breakfast intakes of most macronutrients and micronutrients. In particular, fewer than 25% of participants met the IRBI recommendations for breakfast intakes of dietary fibre, niacin, folate, vitamin C, calcium, potassium and zinc.Conclusions: Almost all preschool-aged children in this study consumed breakfast, but the nutritional quality of their breakfast did not meet recommendations for most nutrients. These results can inform nutrition education and intervention programs for children that aim to improve the nutritional quality of breakfast.

Excess dietary sugar intake increases the risk of unhealthy weight gain, an important cardiometabolic risk factor in children. To further our understanding of this relationship, we performed a narrative review using two approaches. First, research examining dietary sugar intake, its associations with cardiometabolic health, impact of genetics on sweet taste perception and intake, and how genetics moderates the association of dietary sugar intake and cardiometabolic risk factors in preschool-aged children 1.5-5 years old is reviewed. Second, methodological considerations for collecting and analyzing dietary intake of sugar, genetic information, and markers of cardiometabolic health among young children are provided. Our key recommendations include the following for researchers: (1) Further longitudinal research on sugar intake and cardiometabolic risk factors is warranted to inform policy decisions and guidelines for healthy eating in preschool-aged children. (2) Consistency in sugar definitions is needed across research studies to aid with comparisons of results. (3) Select dietary collection tools specific to each study's aim and sugar definition(s). (4) Limit subjectivity of dietary assessment tools as this impacts interpretation of study results. (5) Choose non-invasive biomarkers of cardiometabolic disease until the strengths and limitations of available biomarkers in preschool-aged children are clarified. (6) Select approaches that account for the polygenic nature of cardiometabolic disease such as genome risk scores and genome wide association studies to assess how genetics moderates the relationship between dietary sugar intake and cardiometabolic risk. This review highlights potential recommendations that will support a research environment to help inform policy decisions and healthy eating policies to reduce cardiometabolic risk in young children.
RESUMO
Adopting a healthy diet remains central for the prevention of obesity. In adults, higher intake of ultra-processed food is associated with a greater risk of overweight and obesity. However, little is known about the degree of food processing and its association with anthropometric measures in families with preschool-aged children, a critical period for the development of dietary patterns. This cross-sectional study included preschool-aged children (n = 267) between 1.5 and 5 years of age and their parents (n = 365) from 242 families enrolled in the Guelph Family Health Study. Dietary assessment was completed using ASA24-Canada-2016. Foods and beverages were classified based on their degree of food processing using the NOVA Classification (unprocessed or minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods). Associations between the energy contribution (% kcal) of each NOVA category and anthropometric measures were examined using linear regression models with generalized estimating equations, adjusted for sociodemographic variables. The energy contribution of ultra-processed foods was the highest relative to the other NOVA categories among parents (44.3%) and children (41.3%). The energy contribution of unprocessed or minimally processed foods was 29.1% for parents and 35.3% for children, processed foods was 24.0% for parents and 21.3% for children, and processed culinary ingredients was 2.6% for parents and 2.1% for children. Ultra-processed foods (% kcal) were positively associated with BMI (ß = 0.04, 95% CI: 0.01-0.07, P = 0.02), waist circumference (ß = 0.11, 95% CI: 0.03-0.18, P = 0.008) and body weight (ß = 0.13, 95% CI: 0.03-0.22, P = 0.01) in parents, but not children. Unprocessed foods (% kcal) were negatively associated with waist circumference in parents (ß = -0.09, 95% CI: 0.18-0.01, P = 0.03) and children (ß = -0.03, 95% CI: 0.05-0.01, P = 0.01), as well as body weight (ß = -0.12, 95% CI: 0.23-0.00, P = 0.04) in parents. The degree of food processing primarily influenced anthropometric outcomes in parents. Nevertheless, diets of children were similar, suggesting that such exposure in families may eventually lead to outcomes observed in parents.
RESUMO
Purpose: To determine if intake (servings/day) of total dairy and/or dairy subtypes (milk, cheese, and yogurt) were associated with biomarkers related to dyslipidemia, insulin sensitivity and inflammation in a sample of cardio-metabolically healthy young children from the Guelph Family Health Study at the University of Guelph, Guelph, Ontario, Canada.Methods: Baseline data from 42 children (aged 2.0-6.2 years) from 33 families who provided a dietary assessment and a fasted blood sample were included in this cross-sectional analysis. Linear and logistic regressions using generalized estimating equations were used for analysis and models were adjusted for age, gender, and household income.Results: In total, 42 children (3.74 ± 1.23 years old; mean (± SD)) consumed median (25th percentile, 75th percentile) servings/day of 1.70 (1.16, 2.81) for total dairy, 0.74 (0.50, 1.70) for milk, 0.63 (0.00, 1.16) for cheese, and 0.00 (0.00, 0.38) for yogurt. Cheese intake was significantly inversely associated with LDL cholesterol (-0.16 (95% CI: -0.29, -0.03) mmol/L per serving; P = 0.02)). No other associations between dairy intake and biomarkers were significant.Conclusions: Cheese intake was inversely associated with LDL cholesterol in this preliminary study of cardio-metabolically healthy young children, thereby warranting further research on dairy intake and cardiometabolic risk factors.

There is limited research on the intake of non-nutritive sweeteners (NNS) among preschool-aged children. Canada's Food Guide suggests limiting intake of NNS for all population groups and Health Canada recommends that young children (<2 years) avoid consuming beverages containing NNS. The aim of this study was to investigate the frequency and type of non-nutritive sweetener (NNS) intake in preschool-aged children participating in the Guelph Family Health Study pilots. Parents (n = 78 families) completed 3-day food records (n = 112 children; n = 55 females, n = 57 males; 3.6 years ± 1.3). Nineteen children (17%) reported consumption of foods or beverages containing NNS. Food sources with NNS included: freezies, oral nutritional supplements, flavored water, carbonated drinks, sugar free jam and protein powder. The majority of NNS contained in these foods were identified as stevia leaf extract, acesulfame K, sucralose, monk fruit extract and aspartame. Future research should continue to study NNS intake patterns longitudinally in children and examine the association of NNS intake with diet quality and health outcomes.

BACKGROUND: Excessive intake of sugar in young children is a public health concern. Our study objectives were to examine intakes of total, free and added sugar among preschool-aged children and to investigate their associations with body weight, body mass index Z-scores, percent fat mass and waist circumference. METHODS: The cross-sectional cohort study included preschool-aged children between 1.5 and 5 years of age, enrolled in pilot studies of the Guelph Family Health Study, Guelph, Ontario, from 2014 to 2016. Daily intake of total sugar was determined using a food processor software; daily intakes of free and added sugar, and food sources were determined through manual inspection of 3-day food records. Anthropometric measures were completed by trained research staff. We used linear regression models with generalized estimating equations to estimate associations between sugar intakes and anthropometric measures. RESULTS: We included 109 children (55 girls and 54 boys) in 77 families. Mean daily intakes were 86 (standard deviation [SD] 26) g for total sugar, 31 (SD 15) g for free sugar and 26 (SD 13) g for added sugar. Of participants, 80% (n = 87) had intakes of free sugar greater than 5% of their daily energy intake. The most frequent food sources of free and added sugar were bakery products. A weak inverse association between free sugar intake (kcal/1000 kcal) and waist circumference (cm) (ß = -0.02, 95% confidence interval -0.04 to -0.0009) was found, but no significant associations were noted between sugar intake and other anthropometric measures. INTERPRETATION: Most of the preschool-aged children in this study had free sugar intakes greater than current recommendations; overall, their total, free and added sugar intakes were not associated with the anthropometric measures. This study can be used to inform policy development for sugar intake in young children and apprise early intervention programs.

OBJECTIVE: Approximately 25 % of Canadian children aged 4-8 years fail to meet the recommended dietary allowance (RDA) of calcium (Ca). Young children's food choices are primarily determined by their parents. No interventions have directly targeted parents as a medium through which to increase children's Ca consumption. This study compared the effectiveness of a Ca-specific intervention targeted towards parents, with generic dietary advice on the Ca consumption of children aged 4-10 years. DESIGN: A parallel two-arm randomised controlled trial was conducted. SETTING: The study was conducted across Canada. Both conditions received information on the RDA of Ca and an index of intake requirements. Material sent to the intervention condition included behavioural strategies to increase dietary Ca consumption, information on the benefits of dietary Ca intake and messages addressing perceived barriers to the consumption of Ca-rich foods. PARTICIPANTS: A total of 239 parents (93 % mothers) of children aged 4-10 years who consumed less than the RDA of Ca were randomly assigned in a 1:1 allocation ratio. RESULTS: There was a significant increase in total Ca intake and Ca from dairy for children at weeks 8, 34 and 52 (P ≤ 0·001) in both conditions. Parental Ca intake and amount spent on dairy products did not significantly increase following the intervention. CONCLUSIONS: Provision of daily Ca requirements with regular reminders could impact parents' delivery of Ca-rich foods to their children. This finding is important for public health messaging as it suggests that parents are a potent medium through which to promote Ca intake in children.

OBJECTIVE: To examine the association between self-reported food skills and diet quality along with measured food waste among a sample of Canadian parents. DESIGN: Cross-sectional data from surveys to assess food skills, 3-day food records to assess the Healthy Eating Index (HEI)-2015, and food waste measured by household waste audits. SETTING: Guelph-Wellington, Ontario. PARTICIPANTS: Parents (nâ¯=â¯130) with children aged 2-8 years. MAIN OUTCOME MEASURES: HEI-2015 scores, daily per capita avoidable and unavoidable food waste (grams). ANALYSIS: Linear regression using generalized estimating equations to determine unstandardized ß estimates of associations between food skills and dependent variables. Models were adjusted for multiple testing, gender, and level of education. RESULTS: Food safety knowledge for cooking hot foods (ßâ¯=â¯4.3, Pâ¯=â¯0.05), planning (ßâ¯=â¯4.5, Pâ¯=â¯0.001), and conceptualizing food (ßâ¯=â¯4.0, Pâ¯=â¯0.03) were positively associated with HEI-2015 scores. Knowledge related to best before dates (ßâ¯=â¯25.3, Pâ¯=â¯0.05; ßâ¯=â¯12.1, Pâ¯=â¯0.04), conceptualizing food (ßâ¯=â¯34.1, Pâ¯=â¯0.01; ßâ¯=â¯13.8, Pâ¯=â¯0.02), and mechanical techniques (ßâ¯=â¯39.2, Pâ¯=â¯0.01; ßâ¯=â¯20.5, Pâ¯=â¯0.004) were associated with more avoidable and unavoidable food waste, respectively. CONCLUSIONS AND IMPLICATIONS: Addressing higher-level food skills with a focus on efficient food preparation practices that make use of all edible portions of foods could play an important role in minimizing food waste and improving diet quality. Additional research in other countries and in a larger, more socioeconomically diverse sample is needed to confirm these findings.

OBJECTIVE: This study aimed to explore barriers and facilitators of the provision of dairy and plant-based dairy alternatives (PBDA) by parents of preschool-age children, a previously unexplored area of research. DESIGN: Five focus groups of parents were conducted and audio-recorded. Verbatim transcripts were analysed using thematic analysis. SETTING: University of Guelph, in Guelph, ON, Canada in 2019. PARTICIPANTS: Thirty-two (n 19 mothers, 13 fathers) parents of preschool-age children. Most (59 %) were university or college educated. RESULTS: Facilitators common to both dairy and PBDA provision included perceived nutritional benefits, such as dairy's Ca, protein and fat content, and PBDA's protein content, and the perception that PBDA adds variety to the diet. Facilitators unique to dairy v. PBDA provision included the taste of, familiarity with, and greater variety and accessibility of dairy products, specifically child-friendly products. A facilitator unique to PBDA v. dairy provision was ethical concerns regarding dairy farming practices. Barriers common to both dairy and PBDA provision included perceived cost, concerns regarding the environmental impact of production, and high sugar content. Barriers specific to dairy included use of antibiotics and hormones in dairy production. A barrier specific to PBDA was the use of pesticides. CONCLUSION: Behaviour change messages targeting parents of preschoolers can emphasise the nutrition non-equivalence of dairy and some PBDA and can educate parents on sources of affordable, unsweetened dairy and PBDA.

Purpose: To investigate experiences with, and perceptions of, simulation in learning and using the Nutrition Care Process/Terminology (NCP/T) of dietitians in Canada. Methods: In February-March 2017, a convenience sample of 382 dietitians in Canada (71.8% in clinical practice) completed an online survey regarding the type(s), setting(s), and perceptions of the simulations in which they engaged in learning and using the NCP/T. Results: A majority (76.7%) of respondents had engaged in NCP/T-related simulation, most commonly case studies (85.3%) and role-play (42.0%), as part of workplace/volunteer training (51.4%) and undergraduate internship/stage/practicum (34.2%). Nearly half (49.5%) of respondents learned all 4 NCP components via simulation, with Nutrition Diagnosis being the most common individual component (57%). Over three-quarters of respondents agreed/strongly agreed that simulation helped them better understand/use the NCP/T and that NCP/T-related knowledge/skills gained through simulation are transferable to the clinical setting/dietetic practice. Conclusions: Dietitians in Canada perceive simulation to have helped them learn and use the NCP/T. Resources should be directed at further developing simulation for teaching the NCP/T in dietetics education and training. Research investigating characteristics, barriers, and facilitators of effective NCP/T-simulation, using objective (vs. perceived) learning outcome measures is needed.

Purpose: To investigate dairy and plant-based dairy alternatives (DPBDA) purchasing habits, including comparisons among locations of purchase and among subtypes of DPBDA, of families with preschool-aged children.Methods: Expenditures on food and DPBDA were calculated using grocery and food receipts collected for 3 weeks from 51 households in and around Guelph, Ontario, Canada. DPBDA were coded by subtypes (alternatives, cheese/yogurt, cow's milk, cream, and ice cream/other) and by locations of purchase, which were coded as big-box, discount, high-end, local/other, and midrange stores. Logistic regression using generalized estimating equations was used to investigate odds of purchasing DPBDA by location of purchase. All models included family income and number of children as potential confounders.Results: Ninety-eight percent of families purchased cheese/yogurt, 92% purchased cow's milk, and 35% of families purchased plant-based dairy alternatives. Families were more likely to purchase DPBDA from big-box stores than discount, midrange, or local/other stores (P < 0.01) and were more likely to purchase cheese/yogurt than dairy alternatives, cream, or ice cream/other subtypes (P < 0.01). Odds of purchasing were not different between cheese/yogurt and cow's milk.Conclusion: Families' DPBDA purchasing habits differ by purchase location and subtype. Further research is warranted to understand the factors affecting these purchasing habits.

OBJECTIVE: This study investigated associations between stress (general stress, parenting distress, and household chaos) and adiposity among parents of young children. METHODS: The sample consisted of 49 mothers and 61 fathers from 70 families with young children living in Ontario, Canada. Linear regression using generalized estimating equations was used to investigate associations between stress measures and BMI, waist circumference (WC), waist to height ratio (WHtR), and percent fat mass. RESULTS: General stress was significantly associated with BMI ( ß ^ = 0.54; 95% CI: 0.04-1.03) and WC ( ß ^ = 1.44; 95% CI: 0.10-2.77). Parenting distress was significantly associated with BMI ( ß ^ = 0.16; 95% CI: 0.02-0.31), WC ( ß ^ = 0.39; 95% CI: 0.04-0.75), and WHtR ( ß ^ = 0.003; 95% CI: 0.001-0.005). Household chaos was significantly associated with all adiposity measures (BMI: ß ^ = 0.20 [95% CI: 0.08-0.33]; WC: ß ^ = 0.48 [95% CI: 0.21-0.75]; WHtR: ß ^ = 0.003 [95% CI: 0.001-0.005]; percent fat mass: ß ^ = 0.29 [95% CI: 0.08-0.49]). CONCLUSIONS: General stress, parenting distress, and household chaos are associated with adiposity among parents of young children. Future research should elucidate mechanisms by which this occurs and elucidate how this risk may be mitigated.

OBJECTIVE: To investigate the impact of simulated patients on dietetics students' and interns' communication and nutrition-care competence. DESIGN: Pre-post observational study in which students' communication and nutrition-care competence was evaluated during the first and final clinical nutrition simulations in winter, 2017. SETTING: University of Guelph, Canada. PARTICIPANTS: Seventeen undergraduate students enrolled in Applied Clinical Skills (NUTR*4120) and 15 graduate students/interns enrolled in Practicum in Applied Nutrition II (FRAN*6720). VARIABLES MEASURED: Selected communication and nutrition-care performance indicators (PI) (undergraduatesâ¯=â¯18; graduateâ¯=â¯33) included in the Canadian Integrated Competencies for Dietetic Education and Practice, each measured out of a maximum of 3 points. ANALYSIS: Grand means of communication and nutrition-care PI scores were compared across 2 time points using paired t tests, at a significance level of .05. RESULTS: Undergraduates' (nâ¯=â¯15) communication and nutrition-care PI scores increased by 0.9 ± 0.35 (49.7%) and 0.8 ± 0.22 (45.8%) points, respectively (both P < .001). Graduate students' communication and nutrition-care PI scores increased by 0.4 ± 0.45 (18.5%) and 0.7 ± 0.59 (37.9%) points, respectively (both P < .01). CONCLUSIONS AND IMPLICATIONS: Simulated patients incorporated into clinical nutrition courses increase dietetics students' and interns' communication and nutrition-care competence. More research using comprehensive practice-based competency assessment tools is needed in larger samples of students and interns.

There is growing evidence of an association between the relative reinforcing value of food (RRVF; how hard a child is willing to work for a food versus a non-food reinforcer) and weight across many life stages, but few studies have examined this association among preschool age children. This study investigated the association between the RRVF (measured as the food reinforcing ratio (FRR)) and body mass index (BMI) z-score and percent fat mass (%FM), in 3â¯year-old children. The sample was comprised of 33 children who were 3â¯years of age (36-47â¯months). Children selected their favourite food reinforcer (cookie) and non-food (audiobook) reinforcer to be used in the FRR task, which was delivered using a sequential progressive fixed ratio reward schedule. Child height, weight and percent body fat using bioelectrical impedance analysis were assessed by trained research staff. Linear regression analyses showed that FRR was significantly and positively associated with BMI z-scores. FRR was not significantly associated with %FM. Findings from this study support the RRVF as a potential risk factor in the development of childhood obesity. Longitudinal research involving larger sample sizes would strengthen future research exploring associations between RRVF and body composition in preschool age children.
