    Individuals with self-determined motivation for eating have better overall diet quality : Results from the PREDISE study
    (Academic Press, 2021-05-24) Carbonneau, Élise; Pelletier, Luc; Bégin, Catherine; Lamarche, Benoît; Bélanger, Mathieu; Provencher, Véronique; Desroches, Sophie; Robitaille, Julie; Vohl, Marie-Claude; Couillard, Charles; Bouchard, Luigi; Houle, Julie; Langlois, Marie-France; Rabasa-Lhoret, Rémi; Corneau, Louise; Lemieux, Simone; Corneau, Louise
    The study aimed at documenting motivational orientations for the regulation of eating as defined by self-determination theory and their association with sociodemographic characteristics and overall diet quality. As part of the PREDISE study, French-speaking women (n = 550) and men (n = 547), aged 18-65 years, living in the Province of Québec, Canada, completed online validated questionnaires. The Regulation of Eating Behavior Scale, based on the self-determination theory, assessed self-determined and non-self-determined motivation to regulate one's eating behavior. Three web-based 24-h food recalls were completed and used to compute the Canadian Healthy Eating Index 2007 (C-HEI), an indicator of the overall adherence to Canadian guidelines for healthy eating. Multiple linear regressions were performed to assess how regulation styles are associated with the C-HEI. Model 1 included no covariate, model 2 included sociodemographic covariates, and fully adjusted model 3 included as covariates sociodemographic variables as well as variables that were previously associated with diet quality, namely nutrition knowledge and social support for healthy eating. Women (p < 0.0001), older individuals (p = 0.0002), those with a higher education level (p < 0.0001), and non-smokers (p < 0.0001) reported higher self-determined motivation score than their counterparts. Self-determined motivation was positively (model 1: B = 4.67, p < 0.0001; model 2: B = 3.82, p < 0.0001; model 3: B = 3.61, p < 0.0001) and non-self-determined motivation was negatively (model 1: B = -1.62, p = 0.0009; model 2: B = -1.63, p = 0.0006; model 2: B = -1.49, p = 0.0022) associated with C-HEI. The present study suggests that some subgroups of the general adult population show more self-determined motivation for eating, which is associated with a better diet quality independently of individual characteristics and other individual and social determinants of healthy eating. Strategies to help individuals internalize the regulation of eating should be further investigated.

    Social support, but not perceived food environment, is associated with diet quality in French-speaking Canadians from the PREDISE study
    (M D P I AG, 2019-12-12) Carbonneau, Élise; Bélanger, Mathieu; Couillard, Charles; Corneau, Louise; Lamarche, Benoît; Lemieux, Simone; Vohl, Marie-Claude; Bouchard, Luigi; Robitaille, Julie; Pelletier, Luc G.; Desroches, Sophie; Houle, Julie; Bégin, Catherine; Langlois, Marie-France; Provencher, Véronique
    The objectives were to assess whether social support for healthy eating and perceived food environment are associated with diet quality, and to investigate if sociodemographic characteristics moderate these associations. A probability sample of French-speaking adults from the Province of Québec, Canada, was recruited in the context of the PREDISE study. Participants reported their perceptions of supportive and non-supportive actions related to healthy eating from close others at home and outside of home (n = 952), and of the accessibility to healthy foods (n = 1035). The Canadian Healthy Eating Index (C-HEI) was calculated based on three Web-based 24 h food recalls. Multiple linear regression models showed that supportive (B = 1.50 (95% CI 0.46, 2.54)) and non-supportive (B = −3.06 (95% CI −4.94, −1.18)) actions related to healthy eating from close others at home were positively and negatively associated with C-HEI, respectively, whereas actions from close others outside of home were not. The negative association between non-supportive actions occurring at home and C-HEI was stronger among participants with lower (vs. higher) levels of education (p interaction = 0.03). Perceived accessibility to healthy foods was not associated with C-HEI (p > 0.05). These results suggest that the social environment may have a stronger influence on healthy eating than the perceived physical environment. This adds support for healthy eating promotion programs involving entire families, especially for more socioeconomically disadvantaged individuals, whose efforts to eat healthily may be more easily thwarted by non-supportive households

    A systematic review of the effect of yogurt consumption on chronic diseases risk markers in adults
    (Springer, 2016-11-02) Dugrenier, Marilyn; Lapointe, Annie; Lamarche, Benoît; Dumas, Audrée-Anne; Desroches, Sophie; Provencher, Véronique
    Purpose: We reviewed randomised controlled trials (RCTs) that have assessed the effects of yogurt containing Lactobacillus bulgaricus and Streptococcus thermophilus (LBST) on metabolic risk markers of chronic diseases in adults. Methods: We performed a systematic search in July 2016 in the scientific databases PubMed, EMBASE and The Cochrane Library. Included studies were RCTs that assessed the impact of consuming yogurt containing LBST as a treatment, and that evaluated at least one metabolic risk marker for chronic diseases compared with a control diet or a diet supplemented in another food/ingredient in healthy or chronically ill adults. Results: Seven RCTs involving 278 participants were included in the review. Studies were conducted in the USA, France, Spain, Iran and Canada. Five studies were undertaken in healthy adults, and two were conducted among lactose malabsorbers. All studies investigated changes in blood lipids and glucose homoeostasis, with different doses of yogurt, durations of the supplementation and risks markers assessed. Consumption of LBST yogurt significantly reduced total cholesterol concentrations, ratio of total cholesterol to HDL-C and plasma glucose compared to a control yogurt-free diet or diet supplemented in another food/ingredient in two out of the seven studies. The majority of included RCTs presented high to unclear methodological risks of bias, which raises questions about the validity of their findings. Conclusions: Data from this systematic review indicate that the consumption of LBST yogurt shows either favourable or neutral effects on metabolic risk markers when compared with a control treatment in controlled research settings. RCTs investigating the effect of LBST yogurt consumption on metabolic risk markers of chronic diseases are scarce and presented considerable variation in methodologies making comparison between studies difficult. Further large-scale, well-designed studies assessing the impact of LBST yogurt, in particular in comparison with a control yogurt-free diet, are warranted to effectively evaluate the effect of yogurt consumption per se on risk markers of chronic diseases.

    Evaluation of sports nutrition knowledge and recommendations among high school coaches
    (Human Kinetics Publishers, 2015-08-01) Drapeau, Vicky; Couture, Steven; Goulet, Claude; Lamarche, Benoît; Morissette, Éliane; Valois, Pierre; Provencher, Véronique
    The objectives of this study were to evaluate high school coaches’ knowledge in sports nutrition and the nutritional practices they recommend to their athletes. Forty-seven high school coaches in “leanness” and “non-leanness” sports from the greater region of Quebec (women = 44.7%) completed a questionnaire on nutritional knowledge and practices. “Leanness sports” were defined as sports where leanness or/and low bodyweight were considered important (e.g., cheerleading, swimming and gymnastics), and “non-leanness sports” were defined as sports where these factors are less important (e.g., football). Participants obtained a total mean score of 68.4% for the nutrition knowledge part of the questionnaire. More specifically, less than 30% of the coaches could answer correctly some general nutrition questions regarding carbohydrates and lipids. No significant difference in nutrition knowledge was observed between coaches from “leanness” and “non-leanness” sports or between men and women. Respondents with a university education scored higher than the others (73.3% vs. 63.3%, p < .05). Coaches who participated in coaching certification also obtained better results than those without a coaching certification. The most popular source of information about nutrition used by coaches was the Internet at 55%. The two most popular nutrition practices that coaches recommended to improve athlete performance were hydration and consumption of protein-rich foods. Recommendation for nutritional supplements use was extremely rare and was suggested only by football coaches, a nonleanness sport. Findings from this study indicate that coaches need sports nutrition education and specific training.

    Social support for healthy eating : development and validation of a questionnaire for the French-Canadian population
    (CAB International, 2018-05-28) Carbonneau, Élise; Corneau, Louise; Bradette-Laplante, Maude; Lamarche, Benoît; Lemieux, Simone; Vohl, Marie-Claude; Robitaille, Julie; Desroches, Sophie; Bégin, Catherine; Provencher, Véronique
    Objective: The present study aimed to develop and validate a questionnaire assessing social support for healthy eating in a French-Canadian population. Design: A twenty-one-item questionnaire was developed. For each item, participants were asked to rate the frequency, in the past month, with which the actions described had been done by family and friends in two different environments: (i) at home and (ii) outside of home. The content was evaluated by an expert panel. A validation study sample was recruited and completed the questionnaire twice. Exploratory factor analysis was performed on items to assess the number of subscales. Internal consistency reliability was assessed using Cronbach's ɑ. Test-retest reliability was evaluated with intraclass correlations between scores of the two completions. Setting: Online survey. Subjects: Men and women from the Québec City area (n 150). Results: The content validity assessment led to a few changes, resulting in a twenty-two-item questionnaire. Exploratory factor analysis revealed a two-factor structure for both environments, resulting in four subscales: supportive actions at home; non-supportive actions at home; supportive actions outside of home; and non-supportive actions outside of home. Two items were removed from the questionnaire due to low loadings. The four subscales were found to be reliable (Cronbach's ɑ=0·82-0·94; test-retest intraclass correlation=0·51-0·70). Conclusions: The Social Support for Healthy Eating Questionnaire was developed for a French-Canadian population and demonstrated good psychometric properties. This questionnaire will be useful to explore the role of social support and its interactions with other factors in predicting eating behaviours.

    Intakes of total, free, and naturally occurring sugars in the french-speaking adult population of the province of Québec, Canada : the PREDISE study
    (MDPI Pub., 2019-09-30) Bergeron, Amélie; Bédard, Alexandra; Couillard, Charles; Brassard, Didier; Lamarche, Benoît; Laramée, Catherine; Lemieux, Simone; Vohl, Marie-Claude; Labonté, Marie-Ève; Robitaille, Julie; Desroches, Sophie; Provencher, Véronique
    The objective of this study was to characterize the intakes of different types of sugars in an age- and sex-representative sample of French-speaking adults from five regions of the Province of Québec, Canada, enrolled in the cross-sectional PREDISE (PRÉDicteurs Individuels, Sociaux et Environnementaux) study (n = 1147, 18–65 years old; 50.2% women). Because only total sugar content of foods and beverages is available in the Canadian Nutrient File (CNF) 2015, the initial step of this study was thus to build a database of free and naturally occurring sugars content of each food item and recipe included in the R24W, which is an automated, self-administered, web-based, 24-h dietary recall validated to estimate nutrient intakes in French-speaking adults of the Province of Québec. Total sugars were manually differentiated into free and naturally occurring sugars using a systematic algorithm based on previously published systematic algorithms. The World Health Organization (WHO)’s free sugar definition was used to differentiate total sugars into free and naturally occurring sugars. Dietary intake estimates were assessed using three 24-h dietary recalls completed with the R24W. Mean total, free, and naturally occurring sugar intakes were 116.4 g (19.3% of daily energy intake (%E)), 72.5 g (11.7%E), and 44.0 g (7.5%E), respectively. Over half (57.3%) of the overall sample did not meet the WHO’s recommendation to consume less than 10%E from free sugars. Women had a higher %E from naturally occurring sugars than men and being younger was associated with a greater %E from free sugars. Sugar intakes among French-speaking adults from the Province of Québec were mainly in the form of free sugars, with the majority of the population exceeding the WHO recommendation regarding free sugar intake. This suggests that public health efforts towards reducing free sugar intake in this population are relevant and necessary, considering that overconsumption of free sugars negatively influences health outcomes.

    Associations among eating behaviour traits, diet quality and food labelling : a mediation model
    (Cambridge University Press, 2019-11-26) Drapeau, Vicky; Jacob, Raphaëlle; Pomerleau, Sonia; Doucet, Éric.; Lamarche, Benoît; Provencher, Véronique
    Objective: To assess the associations among eating behaviour traits, food label use and diet quality and to evaluate if the association between eating behaviour traits and diet quality is mediated by food label use. Design: Eating behaviour traits were assessed using the Three-Factor Eating Questionnaire (TFEQ), the Restraint Scale and the Intuitive Eating Scale, whereas food label use was measured with the Label Reading Survey. Diet quality (Canadian Healthy Eating Index) was assessed with an FFQ. Setting: Cross-sectional study. Participants: Adults (n 385; mean (sd): BMI = 26·0 (4·9) kg/m2, age = 41·1 (15·0) years) involved in two previous experimental studies. Results: When controlling for potential covariates, general food label use (β = 1·18 (se 0·26), P < 0·0001) was the main determinant of diet quality, explaining 6·7 % of its variance. General food label use partly mediated the association between TFEQ-cognitive restraint and diet quality; the indirect effect (βindirect (se); 95 % CI) was stronger in men (0·32 (0·10); 0·15, 0·55) than women (0·16 (0·05); 0·08, 0·27). General food label use also partly mediated the negative association between unconditional permission to eat and diet quality; the indirect effect (βindirect (se); 95 % CI) was also stronger in men (−1·88 (0·55); −3·11, −0·96) than women (−1·03 (0·33); −1·81, −0·49). Conclusions: General food label use was the main determinant of diet quality and partly mediated the association between eating behaviour traits and diet quality. The stronger mediating effect observed in men suggests they rely more on food labelling when attempting to restrained themselves, which translates into better diet quality.

    Liking for foods high in salt and fat is associated with a lower diet quality but liking for foods high in sugar is not – Results from the PREDISE study
    (Elsevier, 2020-09-01) Carbonneau, Élise; Lamarche, Benoît; Provencher, Véronique; Desroches, Sophie; Robitaille, Julie; Vohl, Marie-Claude; Bégin, Catherine; Bélanger, Mathieu; Couillard, Charles; Pelletier, Luc; Houle, Julie; Langlois, Marie-France; Rhabasa-Lhoret, Rémi; Corneau, Louise; Lemieux, Simone
    The research aimed at examining how liking for foods high in salt and fat and for foods high in sugar are associated with overall diet quality and how these associations differ according to individual characteristics (i.e., sex, age, education, income, nutrition knowledge, and energy reporting status) in French-speaking adults from the Province of Quebec, Canada. As part of the web-based cross-sectional PREDISE study, 1096 men and women completed online questionnaires. The Food Liking Questionnaire assessed reported liking for a variety of salty foods (high in salt and fat) and sweet foods (high in sugar and either high-fat or low-fat) on a scale from 1 to 9. The Canadian Healthy Eating Index (C-HEI) was computed based on data collected using 24-hour food recalls. Women (vs. men) reported lower liking for salty foods (5.97 ± 1.34 vs. 6.58 ± 1.16, p < 0.0001) and for sweet foods (5.52 ± 1.36 vs. 5.71 ± 1.25, p = 0.015). Multiple linear regressions showed that liking for sweet foods was not associated with C-HEI (B = −0.10, p = 0.78). Given a significant sex interaction in the association between liking for salty foods and C-HEI (p interaction = 0.0218), subsequent analyses were stratified by sex. Multiple linear regressions supported that liking for salty foods was more strongly inversely associated with C-HEI in men (B = −3.37, p < 0.0001) than women (B = −1.46, p = 0.0035). In conclusion, a strong liking for salty foods may interfere with healthy eating, especially in men. Building on these results, future studies should investigate the potential of interventions designed to improve the healthiness of food habits in individuals with strong liking for these foods.

    Development and validation of the food liking questionnaire in a french-canadian population
    (MDPI Pub., 2017-12-08) Carbonneau, Élise; Bradette-Laplante, Maude; Lamarche, Benoît; Vohl, Marie-Claude; Robitaille, Julie; Desroches, Sophie; Bégin, Catherine; Provencher, Véronique
    The purpose of this study was to develop and validate a questionnaire assessing food liking in a French-Canadian population. A questionnaire was developed, in which participants were asked to rate their degree of liking of 50 food items. An expert panel evaluated the content validity. For the validation study, 150 men and women completed the questionnaire twice. An Exploratory Factor Analysis (EFA) was performed to assess the number of subscales of the questionnaire. Internal consistency and test-retest reliability of the subscales were evaluated. Concurrent validity was assessed through correlations between liking scores and self-reported frequencies of consumption. Comments from the experts led to changes in the list of foods included in the questionnaire. The EFA revealed a two-factor structure for the questionnaire (i.e., savory and sweet foods) and led to the removal of nine items, resulting in a 32-item questionnaire. The two subscales revealed good internal consistency (Cronbach alphas: 0.85 and 0.89) and test-retest reliability (p = 0.84 and 0.86). The questionnaire demonstrated adequate concurrent validity, with moderate correlations between food liking and self-reported frequency of consumption (r = 0.19–0.39, ps < 0.05). This new Food Liking Questionnaire assessing liking of a variety of savory and sweet foods demonstrated good psychometric properties in every validation step. This questionnaire will be useful to explore the role of food liking and its interactions with other factors in predicting eating behaviors and energy intake.
