RESUMO

Purpose: Major changes were made to Canada's Food Guide (CFG) in 2019. This study aimed to understand the perceptions of older adults toward this newest version.Methods: Older adults were invited to participate via newsletters sent to older adults and retirees' organizations in the Province of Quebec. Participants completed an online survey about their baseline familiarity with the 2019 CFG using a 5-point Likert scale and took part in an individual semi-structured online interview, which explored their perceptions toward the 2019 CFG. A thematic qualitative analysis of the interview transcripts was performed.Results: Fifty-eight older adults (>65 years, 30 women, 28 men, including 19 consumers and 39 non-consumers of plant-based protein (PBP) foods) participated in the study. Older adults were mostly familiar with the 2019 CFG and had a positive perception of its features. They appreciated the design, proposed recipes, and healthy eating recommendations. Perceptions about the three food groups were mixed, mainly regarding the decreased emphasis on dairy products. Some appreciated that animal proteins were less prominent, while others raised issues on how to integrate PBP into their diet. Perceptions appeared to be influenced by sex and PBP consumption.Conclusion: Older adults in the Province of Quebec view most of the 2019 CFG recommendations positively. Our observations may be useful to dietitians and public health practitioners when developing strategies to improve adherence.

RESUMO

The revised Canada's food guide released in 2019 promotes the consumption of plant-based protein foods (PBP). Yet, older adults consume little of them. This qualitative study aimed to identify older adults' beliefs about consuming PBP and to assess differences in beliefs by gender and baseline PBP consumption. Recruitment was done to obtain an equal number of men and women, 20 PBP-consumers and 40 non-consumers. Each participant completed an online questionnaire collecting sociodemographic data and took part in an individual semi-structured interview based on the Theory of Planned Behavior. A thematic analysis was performed using the Nvivo software. Health benefits, good taste and protecting the environment were perceived as advantages of consuming PBP, whereas difficulty digesting and not liking the taste were reported as disadvantages. Family members were frequently named as people who would approve and/or disapprove the consumption of PBP. Having more knowledge about PBP would facilitate consumption, while lack of motivation to change eating habits and lack of knowledge on how to prepare PBP meals were perceived barriers. Several differences in beliefs by gender and baseline PBP consumption were observed. Future interventions should focus on the beliefs that were identified as important to older adults (i.e., health benefits and food preparation skills), and should be tailored to their gender and PBP consumption.

RESUMO

The overarching goal of this study was to examine the unique contribution of psychological, familial, and friendship factors in explaining anorexia nervosa (AN) symptom severity 1 year following diagnosis among a sample of adolescent girls. A second objective was to determine whether friendship factors mediated the association between psychological and/or familial factors and AN symptom severity. This study included 143 adolescent girls under the age of 18 diagnosed with AN (M = 14.84, SD = 1.31). Participants were recruited from specialized eating disorder treatment programs. At admission (T1), participants completed a set of self-report questionnaires measuring psychological, familial, and friendship factors. AN symptom severity was assessed 1 year later (T2). Results of hierarchical regression analysis revealed that greater general psychological maladjustment at T1 (b = .26; se = .03; p = .00) was associated with greater AN symptom severity at T2. Greater alienation from friends at T1 (b = 1.20, se = .53, p = .03) also predicted greater AN symptom severity at T2, above and beyond the influence of adolescent girls' general psychological maladjustment. Finally, the mediating role of alienation from friends in the association between general psychological maladjustment at T1 and AN symptom severity at T2 was also identified. AN is a multidimensional disorder with a prognosis that involves both psychological and social factors. The results stemming from the present study shed light on the role of peer as a mechanism through which general psychological maladjustment is linked to AN symptom severity 1 year following diagnosis.

RESUMO

The purpose of this study was to develop and validate a questionnaire assessing eating pleasure dimensions in the adult French-speaking population of the province of Québec, Canada. We developed the Eating Pleasure Questionnaire, a 53-item questionnaire. An expert panel evaluated the content validity, and a pre-test was performed with 30 French-speaking Quebecers (15 men and 15 women, mean age = 46 years) to evaluate the face validity. A sample of 300 Quebecers (150 men and 150 women, mean age = 36 years) completed the online questionnaire for validation. The structure of the questionnaire was examined using exploratory factor analysis (EFA). Internal consistency was evaluated with Cronbach's alpha coefficients. Test-retest reliability was assessed using intra class correlation coefficients (ICC) and construct validity, using Pearson's correlations. Evaluation of content validity and face validity led to the clarification of the instructions, the suppression of two items, the addition of two items and some reformulations. The EFA showed a 7-factor structure: 1- health/ideological food choice motives, 2- sensory experiences and individual preferences, 3- social experiences, 4- mindful eating, 5- emotional/situational eating and reward, 6- food preparation process and 7- new experiences. Cronbach's alpha values for the seven factors ranged from 0.67 to 0.86. The total scale Cronbach's alpha was 0.91, which suggests a good internal consistency. The questionnaire appears reliable with ICC ranging from 0.66 to 0.87. It also showed a good construct validity, with expected positive associations with food well-being (how people link food to well-being), intrinsic motivation, and the pleasure orientation (the importance of obtaining pleasure from food). Overall, these analyses suggest that the Eating Pleasure Questionnaire is valid to evaluate eating pleasure dimensions in our population.

RESUMO

OBJECTIVE: Given the growing interest in personality traits among the young population with eating disorders (EDs) and the recognition that a better understanding of personality can facilitate clinical management, this meta-analytic study reviewed evidence concerning the relationship between personality traits and the presence of an ED during adolescence. METHOD: We conducted a systematic literature search to identify studies that examined personality traits among adolescents with an ED (anorexia nervosa, bulimia nervosa, binge-eating disorder, eating disorder not otherwise specified) and that compared these traits with a normative group without an ED. The personality traits investigated in the selected studies were organized according to the personality trait domains presented in the Diagnostic and Statistical Manual of Mental Disorders (fifth ed.). Effect sizes of the mean differences were calculated for each domain. We performed meta-regressions to assess the moderating effect of ED subtype and age on the combined effect sizes. RESULTS: Twenty-six studies met our inclusion criteria, containing a total of 63 effect sizes. Adolescents with EDs differed from the non-ED group according to traits related to negative affectivity (g = 0.78), detachment (g = 0.69), and conscientiousness (g = -0.53). The presence of an anorexia nervosa diagnosis moderated the relationship between an ED and personality traits; this diagnosis was more strongly associated with conscientious traits compared to other EDs. DISCUSSION: Our findings provide evidence that personality traits are related to EDs in adolescents. Thus, considering personality traits could lead to a better understanding of etiological and maintenance factors for EDs.

RESUMO

Some authors have suggested that eating pleasure is underused to promote healthy eating. However, little is known about the potential of pleasure-oriented messages to lead to healthier food choices. The aim of this study was to examine the effects of pleasure- and health-oriented messages on food choices made from a buffet. One hundred and ninety-eight participants (50% women), unaware of the real objective of the study, were randomized in three groups: 1) pleasure, 2) health, and 3) control. They first completed three 24 h food recalls to assess their overall diet quality using the Canadian Healthy Eating Index (C-HEI; score: 0 to 100). Thereafter, participants came to the research institute and those randomized in the "pleasure" and "health" groups read a leaflet on healthy eating, using either a pleasure or a health orientation respectively. Participants in the control group had no leaflet to read. All participants had subsequently to choose four food items in a buffet offering both healthy and unhealthy foods. Results showed a group by diet quality interaction (p = 0.02). Among participants with lower diet quality (C-HEI score below 50), those in the pleasure and health groups were more likely than participants in the control group to choose a healthier main course (prevalence ratios (PR) 1.71, 95% CI 1.12-2.62 and 1.83, 95% CI 1.21-2.77 for the pleasure and health group respectively) and a healthier beverage (PR 1.67, 95% CI 1.02-2.71 and 1.66, 95% CI 1.02-2.72, respectively). No such effect was observed among participants with higher C-HEI scores. In conclusion, our results suggest that in people with sub-optimal dietary habits, pleasure-oriented messages and traditional health messages are both useful to favor healthy main course and beverage choices.

RESUMO

Given that traditional interventions promoting the adoption of a healthy diet are having limited impacts on the population's food choices and eating behaviours, researchers and health practitioners could explore alternative strategies such as the use of eating pleasure to promote healthy eating. To inform future interventions using this approach, this study aimed to explore how a sample of Quebecers perceives and defines eating pleasure and healthy eating. Specific objectives were to verify what commonalities can be found between their definitions of eating pleasure and healthy eating, and what differences can be observed in their answers based on their sex and body mass index (BMI). Twelve focus groups were conducted in Quebec City, Canada, among women and men with a normal weight and with obesity (n = 92). Verbatim transcripts were double-coded using NVivo10. Participants mostly defined eating pleasure through food characteristics related to sensory qualities and psychosocial contexts. In contrast, they mostly mentioned food characteristics related to nutritional quality and ways to regulate eating behaviours to define healthy eating. Most salient perceptions were similar among subgroups based on sex or BMI. Results showed that in participants' perceptions, the concepts of eating pleasure and healthy eating were different, but appeared to be mostly compatible, which makes the integration of eating pleasure a promising avenue for interventions promoting healthy eating.

RESUMO

PURPOSE: To determine whether an intervention based mainly on exposure to the Mediterranean diet (MedDiet), along with recommendations and tools for encouraging healthy eating, lead to different effects on dietary adherence and body weight management six months post-intervention in Canadian men and women. METHODS: Thirty-eight males and 32 premenopausal females (all aged 24-53 years) were exposed to the same 4-week experimental MedDiet during which all foods were provided to participants. Participants also received some recommendations and tools to adhere to a healthy way of eating, with no other contact until the 6-month follow-up visit. RESULTS: Compared with baseline, the Mediterranean score (MedScore) increased at the end of the 6-month follow-up (time effect P = 0.003), with no sex difference (sex-by-time interaction P = 0.97). With regard to MedScore components, sex differences were observed with males reporting changes in more dietary food groups than females. Although the intervention was not focused on body weight management, compared with baseline, BMI decreased during the intervention in both males and females; however, only females maintained the lower BMI 6 months after the intervention. CONCLUSIONS: Exposure to the MedDiet for a short duration promotes the adherence to this food pattern in both sexes and helps in the management of body weight, especially in females.

RESUMO

BACKGROUND: Some intervention trials have reported a reduction in systemic inflammation with the Mediterranean diet (MedDiet) while others have observed no effect. Despite the fact that sex differences have been highlighted in the inflammatory regulation, it is still not known whether MedDiet exerts similar effects on systemic inflammation in men and women. The aim of this study was therefore to investigate sex differences in the effects of the MedDiet on high-sensitivity C-reactive protein (hs-CRP). FINDINGS: Participants were 35 men and 27 premenopausal women (24-53 years) presenting a slightly deteriorated lipid profile. All foods were provided to participants during a 4-week isocaloric MedDiet. At baseline, women had higher hs-CRP concentrations than men (P = 0.03). No sex difference was observed in hs-CRP response to the MedDiet (P for sex-by-time interaction = 0.36), with both men and women experiencing no change (respectively P = 0.62 and P > 0.99). When subgroups were formed according to hs-CRP concentration before the MedDiet phase, men with elevated baseline values (≥2 mg/l) experienced a reduction in hs-CRP over time with the MedDiet (-26.5 %) while an increase was observed in men with lower baseline values (+96.6 %; P for group-by-time interaction = 0.02). This pattern of change was not observed in women. CONCLUSIONS: Results from this controlled feeding study suggest that men and women have similar effects from the MedDiet on systemic inflammation. The individual's overall inflammatory status seems to influence these effects, but only in men. TRIAL REGISTRATION: This clinical trial was registered at www.clinicaltrials.gov as NCT01293344 .

RESUMO

The primary objective of this study was to examine how social desirability is associated with self-reported measures of dietary intakes and variables related to attitudes and behaviours towards eating. This analysis was conducted in 1083 adults (50.0% women) from the PREDISE study. Social desirability was assessed using the Balanced Inventory of Desirable Responding (BIDR) questionnaire, which includes two subscales: (1) self-deceptive enhancement (SDE), i.e., having an overly positive self-image and (2) impression management (IM), i.e., intentional response distortion to please. BIDR total score and IM subscore were positively associated with the Canadian Healthy Eating Index (C-HEI) (ß = 0.24 and ß = 0.50; p ≤ 0.0003), calculated using data from three self-administered 24 h food recalls. All BIDR scores were positively associated with self-determined motivation for eating regulation (0.03 ≤ ß ≤ 0.06; p < 0.0001), measured by the Regulation of Eating Behavior Scale, and with the intuitive eating score (0.02 ≤ ß ≤ 0.05; p < 0.0001). Also, all BIDR scores were negatively associated with hunger and disinhibition scores measured by the Three-Factor Eating Questionnaire (-0.17 ≤ ß ≤ -0.09; p < 0.0001). All these associations were adjusted for age, sex, BMI, and the education level. Furthermore, controlling for both dimensions of social desirability did not impact the magnitude of the association between self-determined motivation (the strongest predictor of healthy eating in the PREDISE study) and C-HEI. According to our results, associations are observed with diet quality, as well as with attitudes and behaviours towards eating; therefore, a measurement of social desirability responding would be pertinent in studies using those or related variables.

RESUMO

The aim of this study was to identify eating-related latent profiles based on diet quality and eating behaviours within a population characterized by a body mass index (BMI) of at least 25 kg/m2, and to compare metabolic variables between profiles. This analysis was conducted in a sample of 614 adults (45.6% women; 44.8 ± 12.9 years) from the cross-sectional PREDISE study. Participants completed the Three-Factor Eating Questionnaire, the Intuitive Eating Scale-2, the Regulation of Eating Behavior Scale, and three self-administered 24 h food recalls. Waist circumference, blood lipids, blood pressure, and fasting glucose were measured to identify carriers of the metabolic syndrome. A latent profile analysis was performed, and cases of metabolic syndrome were compared between profiles. A three-profile solution was found. Profile 1 (22.8%) was characterized by lower diet quality, lower self-determined motivation for eating, lower restraint, and higher intuitive eating. Profile 2 (44.5%) was characterized by higher diet quality, higher self-determined motivation for eating, higher restraint, lower disinhibition, and higher intuitive eating. Profile 3 (32.7%) was characterized by intermediate diet quality, higher non-self-determined motivation for eating, higher restraint and disinhibition, and lower intuitive eating. We found fewer cases of metabolic syndrome among participants in profile 2 than in the other profiles (p = 0.0001). This study suggests that a profile characterized by a lower disinhibition and higher levels of restraint, intuitive eating, self-determined motivation, and diet quality is associated with a better metabolic health among individuals with a higher BMI.

RESUMO

Background: This study aimed to document recovery trajectories among adolescents with anorexia nervosa (AN) based on three markers of remission, namely changes in body weight, food restriction, and excessive exercise, and to identify predictors of these trajectories. Methods: One hundred twenty-six adolescent girls (14.7 ± 1.3 years) were recruited during initial assessment visits at specialized eating disorder (ED) programs in five University Health Centers across the province of Quebec, Canada. z-BMI and AN symptom severity (food restriction and excessive exercise) were assessed at initial assessment visits and subsequently reassessed at each quarterly follow-up over a 12-month period to identify recovery trajectories. Results: Considering the three markers of remission, three distinct trajectories emerged: Group 1, rapid responders; Group 2, gradual responders; and Group 3, unstable responders. At initial visits, a difference between groups was found regarding the type of treatment (p = 0.01) and weight suppression (p = 0.02). Group 1 had a higher number of youths hospitalized than Group 2 and Group 3, and a greater weight suppression than Group 3. Furthermore, individuals with atypical AN were more likely to belong to Group 2 than to Group 1 and Group 3 (p < 0.0001). Conclusions: This study contributes to a better understanding of the heterogeneity of recovery trajectories in adolescent girls with AN.

RESUMO

Efforts to develop effective strategies that improve dietary intake are needed; however, this improvement in diet quality must not be at the expense of well-being. The Well-Being related to Food Questionnaire (Well-BFQ©) is a tool that has been developed in France to comprehensively measure food well-being. Even though the same language is spoken in France and in Québec, cultural and linguistic differences are present, which supports the importance of adapting and validating this tool before its use in the Québec population. This study aimed to adapt and validate the Well-BFQ© for the French-speaking general adult population of Québec, Canada. The Well-BFQ© underwent a full linguistic adaptation process, including an expert panel adaptation step, a pretest among 30 French-speaking adult (18-65 years) Quebecers, and a final proofreading. The questionnaire was thereafter administered to 203 French-speaking adult Quebecers (49.3% females, MAGE = 34.9, SD = 13.5; 88.2% Caucasians; 54.2% with a university degree). The exploratory factor analysis showed a two-factor structure: (1) food well-being related to physical and psychological health (27 items) and (2) food well-being related to symbolic/pleasure of food (32 items). Internal consistency was adequate, with a Cronbach's α of 0.92 and 0.93, respectively, for the subscales, and 0.94 for the total scale. The total food well-being score, as well as the two subscale scores, were associated with psychological and eating-related variables in expected directions. Overall, the adapted version of the Well-BFQ© was found to be a valid instrument to measure food well-being in the French-speaking general adult population of Québec, Canada.

RESUMO

NOVELTY: The Canadian Food Intake Screener was developed to rapidly assess alignment of adults' dietary intake over the past month with the Food Guide's healthy food choices recommendations. The screener was developed and evaluated through an iterative process that included three rounds of cognitive interviews in each of English and French, along with ongoing feedback from external advisors and face and content validity testing with a separate panel of content experts. The 16-question screener is intended for use with adults, aged 18-65 years, with marginal and higher health literacy in research and surveillance contexts in which comprehensive dietary assessment is not possible.

RESUMO

In 2019, Health Canada released a new iteration of Canada's Food Guide (2019-CFG), which, for the first time, highlighted recommendations regarding eating practices, i.e., guidance on where, when, why, and how to eat. The objective of this study was to develop a brief self-administered screener to assess eating practices recommended in the 2019-CFG among adults aged 18-65 years. Development of the screener items was informed by a review of existing tools and mapping of items onto 2019-CFG recommendations. Face and content validity were assessed with experts in public health nutrition and/or dietary assessment (n = 16) and individuals from Government of Canada (n = 14). Cognitive interviews were conducted with English-speaking (n = 16) and French-speaking (n = 16) adults living in Canada to assess face validity and understanding of the screener items. While some modifications were identified to improve relevance or clarity, overall, the screener items were found to be relevant, well-constructed, and clearly worded. This comprehensive process resulted in the Canadian Eating Practices Screener/Questionnaire court canadien sur les pratiques alimentaires, which includes 21 items that assess eating practices recommended in the 2019-CFG. This screener can facilitate monitoring and surveillance efforts of the 2019-CFG eating practices as well as research exploring how these practices are associated with various health outcomes.

RESUMO

The traditional Mediterranean diet (MedDiet) is now widely recommended in the prevention of CVD. However, it is not known whether the MedDiet has the same beneficial cardiovascular effects in women and in men. The objective of the present study was to investigate sex-related differences with regard to changes in cardiometabolic variables in response to a 4-week isoenergetic MedDiet. Participants were thirty-eight men and thirty-two premenopausal women aged between 25 and 50 years who had slightly elevated LDL-cholesterol (LDL-C) concentrations (3·4-4·9 mmol/l) or total cholesterol:HDL-cholesterol ratio ≥ 5·0. A 4-week run-in period preceded the MedDiet in order to control the inter- and intra-individual variability. Cardiometabolic variables were measured before and after the MedDiet. Total cholesterol, LDL-C, apoB and apoA-1 plasma concentrations as well as diastolic blood pressure decreased (P < 0·05) in both men and women (respectively, 10, 10, 10, 6 and 5% for men and 6, 7, 9, 4 and 4% for women). ApoA-2 concentrations and insulin concentrations 2 h after the oral administration of 75 g of glucose demonstrated sex × time interactions (respectively, P = 0·05 and P = 0·03) and only men experienced a decrease for these variables (respectively, 8 and 25%). In conclusion, consuming a MedDiet led to significant changes in plasma lipid profile in both men and women, while only men had significant improvements in insulin homeostasis. These results support the importance of investigating sex-related differences in response to diet in order to perhaps further individualise dietary guidelines in the prevention of CVD and type 2 diabetes.

RESUMO

OBJECTIVE: Women with impaired glucose tolerance (IGT) and type 2 diabetes (T2D) are more at risk of cardiovascular disease. The aim of this study was to test the hypothesis that increased visceral adipose tissue (VAT) could explain to a large extent alterations in the cardiovascular disease risk profile of postmenopausal women with IGT or T2D. DESIGN, PATIENTS AND MEASUREMENTS: Sixty-two women with normal glucose tolerance (NGT), 33 with IGT and 18 with de novo diagnosed T2D were tested. The sample was further divided into five groups: (i) NGT-low VAT (<130 cm(2) ); (ii) NGT-high VAT (≥130 cm(2)); (iii) IGT-low VAT (<130 cm(2) ); (iv) IGT-high VAT (≥130 cm(2) ) and (v) T2D. RESULTS: Women with T2D, women with IGT-high VAT and those with NGT-high VAT all had lower insulin sensitivity as determined by the euglycaemic-hyperinsulinaemic clamp (M_I), higher triglyceride (TG), lower HDL(2)-cholesterol (chol) levels and higher levels of high-sensitivity C-reactive protein than women with NGT-low VAT. Only differences in M_I and early insulin response (EIR) were observed between women with IGT-high VAT and those with NGT-high VAT (lower values in IGT-high VAT). Women with T2D had lower M_I and EIR as well as higher plasma TG and lower plasma Apo A1 and HDL-chol concentrations than women with NGT-high VAT. CONCLUSIONS: Our results suggest that increase in VAT accumulation usually found in women with IGT explains to a large extent the deterioration in their plasma lipid-lipoprotein and inflammatory profile. However, factors other than VAT are involved in explaining the high TG-low HDL dyslipidaemia observed in women with T2D.

RESUMO

It is expected that a dietary intervention based on the traditional Mediterranean food pattern should be associated with a reduction in fast-food consumption but this has never been tested before. We assessed the impact of a 12-week dietary intervention, promoting the adoption of a Mediterranean food pattern, on fast-food consumption among seventy-one healthy women aged between 30 and 65 years. The dietary intervention consisted of two group sessions and seven individual sessions with a dietitian. To determine the Mediterranean dietary score (MedScore) and fast-food consumption, an FFQ was administered. During the 12-week intervention, the MedScore significantly increased (from 21.1 (SD 3.6) units at baseline to 28.6 (SD 4.4) units at week 12, P < 0.0001), while the fast-food consumption significantly decreased (from 51.7 (SD 46.4) g/d at baseline to 20.5 (SD 18.2) g/d at week 12, P < 0.0001). Moreover, women who had a higher consumption of fast food at baseline decreased their fast-food consumption to the most (r - 0.50, P < 0.0001). When four subgroups were formed on the basis of median values of Medscore and fast-food consumption changes, it was found that only the subgroup of women which increased the most their MedScore and decreased the most their fast-food consumption experienced a significant decrease in BMI (P < 0.01). In conclusion, a dietary intervention promoting the Mediterranean food pattern led to a decrease in fast-food consumption among healthy women even if it was not a specific target of the intervention. Dietary strategies for increasing intake of healthy foods may be a useful approach for decreasing intake of less healthy foods.

RESUMO

The aims of this review were to map and summarize data currently available about 1) key dimensions of eating pleasure; 2) associations of eating pleasure, and its key dimensions, with dietary and health outcomes and 3) the most promising intervention strategies using eating pleasure to promote healthy eating. Using the scoping review methodology, a comprehensive search of the peer-reviewed literature (Medline, PsycInfo, Embase, ERIC, Web of Science, CINAHL, ABI/Inform global and Sociology Abstract) and of the grey literature (ProQuest Dissertations & Theses and Google) was carried out by two independent reviewers. We included 119 of the 28,908 studies found. In total, 89 sub-dimensions of eating pleasure were grouped into 22 key dimensions. The most frequently found related to sensory experiences (in 50.9% of the documents), social experiences (42.7%), food characteristics besides sensory attributes (27.3%), food preparation process (19.1%), novelty (16.4%), variety (14.5%), mindful eating (13.6%), visceral eating (12.7%), place where food is consumed (11.8%) and memories associated with eating (10.9%). Forty-five studies, mostly cross-sectional (62.2%), have documented links between eating pleasure and dietary and/or health outcomes. Most studies (57.1%) reported favorable associations between eating pleasure and dietary outcomes. For health outcomes, results were less consistent. The links between eating pleasure and both dietary and health outcomes varied according to the dimensions of eating pleasure studied. Finally, results from 11 independent interventions suggested that strategies focusing on sensory experiences, cooking and/or sharing activities, mindful eating, and positive memories related to healthy food may be most promising. Thus, eating pleasure may be an ally in the promotion of healthy eating. However, systematically developed, evidence-based interventions are needed to better understand how eating pleasure may be a lever for healthy eating.

RESUMO

BACKGROUND: Existing initiatives to promote healthy eating remain largely ineffective as individuals struggle to adhere to dietary recommendations. Therefore, challenging the strategies currently used is of significant importance. Recent studies have indicated the potential of an approach oriented towards eating pleasure to promote the consumption of healthy foods. OBJECTIVES: The aim of this study was to compare perceptions and the potential effect of pleasure-oriented and health-oriented messages promoting healthy eating among French-Canadians. METHODS: Two leaflets similar in all respects, except for the message orientation (pleasure or health), were developed. Perceived message orientation and effectiveness, perceptions towards healthy eating as well as emotions, attitude towards healthy eating, and intention to eat healthily were evaluated. A total of 100 adults (50% women; mean ± SD age 45.1 ± 13.0 y) were randomly assigned to read 1 of the 2 leaflets (pleasure: n = 50; health: n = 50). Questionnaires were completed online and data were also collected at a visit made to the Institute of Nutrition and Functional Foods. RESULTS: The difference in message orientation (pleasure compared with health) was well perceived by participants (P ≤ 0.01). The pleasure-oriented message was successful in inducing the perception that eating healthy can be pleasurable (pre- compared with post-reading; P = 0.01). Perceived message effectiveness and induced emotions in response to reading were similar between leaflets. Both messages significantly improved global attitude towards healthy eating (P ≤ 0.01) and increased intention to eat healthily (P < 0.001). Additional analyses showed that the affective attitude towards healthy eating increased more after reading the pleasure leaflet than the health leaflet (P = 0.05), whereas the health message tended to improve cognitive attitude more than the pleasure leaflet (P = 0.06). CONCLUSIONS: These findings suggest that the leaflets would be appropriate to promote healthy eating through 2 distinct approaches (health and pleasure paradigms) and propose that different effects on attitude could be observed from these 2 approaches.
