Food environment research in Canada: a rapid review of methodologies and measures deployed between 2010 and 2021.

Numerous research methodologies have been used to examine food environments. Existing reviews synthesizing food environment measures have examined a limited number of domains or settings and none have specifically targeted Canada. This rapid review aimed to 1) map research methodologies and measures that have been used to assess food environments; 2) examine what food environment dimensions and equity related-factors have been assessed; and 3) identify research gaps and priorities to guide future research. A systematic search of primary articles evaluating the Canadian food environment in a real-world setting was conducted. Publications in English or French published in peer-reviewed journals between January 1 2010 and June 17 2021 and indexed in Web of Science, CAB Abstracts and Ovid MEDLINE were considered. The search strategy adapted an internationally-adopted food environment monitoring framework covering 7 domains (Food Marketing; Labelling; Prices; Provision; Composition; Retail; and Trade and Investment). The final sample included 220 articles. Overall, Trade and Investment (1%, n = 2), Labelling (7%, n = 15) and, to a lesser extent, Prices (14%, n = 30) were the least studied domains in Canada. Among Provision articles, healthcare (2%, n = 1) settings were underrepresented compared to school (67%, n = 28) and recreation and sport (24%, n = 10) settings, as was the food service industry (14%, n = 6) compared to grocery stores (86%, n = 36) in the Composition domain. The study identified a vast selection of measures employed in Canada overall and within single domains. Equity-related factors were only examined in half of articles (n = 108), mostly related to Retail (n = 81). A number of gaps remain that prevent a holistic and systems-level analysis of food environments in Canada. As Canada continues to implement policies to improve the quality of food environments in order to improve dietary patterns, targeted research to address identified gaps and harmonize methods across studies will help evaluate policy impact over time.

Acupuncture for menopausal hot flushes.

BACKGROUND: Hot flushes are the most common menopausal vasomotor symptom. Hormone therapy (HT) has frequently been recommended for relief of hot flushes, but concerns about the health risks of HT have encouraged women to seek alternative treatments. It has been suggested that acupuncture may reduce hot flush frequency and severity. OBJECTIVES: To determine whether acupuncture is effective and safe for reducing hot flushes and improving the quality of life of menopausal women with vasomotor symptoms. SEARCH METHODS: We searched the following databases in January 2013: the Cochrane Menstrual Disorders and Subfertility Group Specialised Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, CINAHL, PsycINFO, Chinese Biomedical Literature Database (CBM), Chinese Medical Current Content (CMCC), China National Knowledge Infrastructure (CNKI), VIP database, Dissertation Abstracts International, Current Controlled Trials, Clinicaltrials.gov, National Center for Complementary and Alternative Medicine (NCCAM), BIOSIS, AMED, Acubriefs, and Acubase. SELECTION CRITERIA: Randomized controlled trials comparing any type of acupuncture to no treatment/control or other treatments for reducing menopausal hot flushes and improving the quality of life of symptomatic perimenopausal/postmenopausal women were eligible for inclusion. DATA COLLECTION AND ANALYSIS: Sixteen studies, with 1155 women, were eligible for inclusion. Three review authors independently assessed trial eligibility and quality, and extracted data. We pooled data where appropriate and calculated mean differences (MDs) and standardized mean differences (SMDs) with 95% confidence intervals (CI). We evaluated the overall quality of the evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. MAIN RESULTS: Eight studies compared acupuncture versus sham acupuncture. No significant difference was found between the groups for hot flush frequency (MD -1.13 flushes per day, 95% CI -2.55 to 0.29, 8 RCTs, 414 women, I(2) = 70%, low-quality evidence) but flushes were significantly less severe in the acupuncture group, with a small effect size (SMD -0.45, 95% CI -0.84 to -0.05, 6 RCTs, 297 women, I(2) = 62%, very-low-quality evidence). There was substantial heterogeneity for both these outcomes. In a post hoc sensitivity analysis excluding studies of women with breast cancer, heterogeneity was reduced to 0% for hot flush frequency and 34% for hot flush severity and there was no significant difference between the groups for either outcome.Three studies compared acupuncture versus HT. Acupuncture was associated with significantly more frequent hot flushes than HT (MD 3.18 flushes per day, 95% CI 2.06 to 4.29, 3 RCTs, 114 women, I(2) = 0%, low-quality evidence). There was no significant difference between the groups for hot flush severity (SMD 0.53, 95% CI -0.14 to 1.20, 2 RCTs, 84 women, I(2) = 57%, low-quality evidence).One study compared electroacupuncture versus relaxation. There was no significant difference between the groups for either hot flush frequency (MD -0.40 flushes per day, 95% CI -2.18 to 1.38, 1 RCT, 38 women, very-low-quality evidence) or hot flush severity (MD 0.20, 95% CI -0.85 to 1.25, 1 RCT, 38 women, very-low-quality evidence).Four studies compared acupuncture versus waiting list or no intervention. Traditional acupuncture was significantly more effective in reducing hot flush frequency from baseline (SMD -0.50, 95% CI -0.69 to -0.31, 3 RCTs, 463 women, I(2) = 0%, low-quality evidence), and was also significantly more effective in reducing hot flush severity (SMD -0.54, 95% CI -0.73 to -0.35, 3 RCTs, 463 women, I(2) = 0%, low-quality evidence). The effect size was moderate in both cases.For quality of life measures, acupuncture was significantly less effective than HT, but traditional acupuncture was significantly more effective than no intervention. There was no significant difference between acupuncture and other comparators for quality of life. Data on adverse effects were lacking. AUTHORS' CONCLUSIONS: We found insufficient evidence to determine whether acupuncture is effective for controlling menopausal vasomotor symptoms. When we compared acupuncture with sham acupuncture, there was no evidence of a significant difference in their effect on menopausal vasomotor symptoms. When we compared acupuncture with no treatment there appeared to be a benefit from acupuncture, but acupuncture appeared to be less effective than HT. These findings should be treated with great caution as the evidence was low or very low quality and the studies comparing acupuncture versus no treatment or HT were not controlled with sham acupuncture or placebo HT. Data on adverse effects were lacking.

Availability of calorie information on online food delivery service platforms among major chain restaurants in Canadian provinces with different calorie labelling policies.

OBJECTIVE: This study aimed to characterize the availability of calorie labelling on major online food delivery (OFD) platforms for the largest restaurant brands in Canada to examine differences in provinces with and those without mandatory calorie labelling regulations. METHODS: Data were collected for the 13 largest restaurant brands with locations in Ontario (with mandatory menu labelling) and Alberta and Quebec (with no mandatory menu labelling) from the web applications of the three largest OFD platforms in Canada. Data were sampled from three selected restaurant locations within each province (n = 117 locations across all provinces) on each platform. Univariate logistic regression models were used to test differences in the presence and amount of calorie labelling and other nutritional information across provinces and platforms. RESULTS: The analytical sample included 48,857 food and beverage items (n = 16,011 in Alberta, n = 16,683 in Ontario, and n = 16,163 in Quebec). Items were more likely to have menu labelling in Ontario (68.7%) than in Alberta (44.4%, OR = 2.75, 95% CI 2.63-2.88) or Quebec (39.1%, OR = 3.42, 95% CI 3.27-3.58). In Ontario, 53.8% of restaurant brands had calorie labelling for > 90% of items, compared to 23.0% in Quebec and 15.4% in Alberta. The presence of calorie labelling also differed across platforms. CONCLUSION: Nutrition information from OFD services differed across provinces with and those without mandatory calorie labelling. Chain restaurants on OFD service platforms were more likely to provide calorie information in Ontario, where calorie labelling is mandatory, compared to elsewhere where no such policy exists. In all provinces, calorie labelling was inconsistently implemented across OFD service platforms.

RéSUMé: OBJECTIF: Cette étude vise à caractériser la disponibilité de l'affichage des calories sur les principales plateformes de service de livraison de repas en ligne (SLRL) pour les plus grandes chaines de restaurants au Canada pour évaluer les différences entre les provinces dotées d'une réglementation sur l'étiquetage obligatoire des calories et celles où une telle politique est inexistante. MéTHODOLOGIE: Les données ont été recueillies pour les 13 plus grandes chaines de restaurants ayant des établissements en Ontario (avec étiquetage des menus obligatoire) et en Alberta et au Québec (étiquetage des menus non obligatoire) sur les applications web des trois principales plateformes de SLRL au Canada. Les données ont été échantillonnées à partir de trois succursales pour chaque chaine de restaurants dans chacune des provinces (n = 117 restaurants dans toutes les provinces) sur chaque plateforme. Des modèles de régression logistique univariés ont été utilisés pour tester les différences dans la présence et la prévalence de l'affichage des calories et d'autres informations nutritionnelles entre les provinces et les plateformes. RéSULTATS: L'échantillon analysé comprenait 48 857 produits alimentaires et boissons (n = 16 011 en Alberta, n = 16 683 en Ontario et n = 16 163 au Québec). Les calories étaient plus susceptibles d'être affichées sur les produits en Ontario (68,7 %) comparativement à l'Alberta (44,4 %, RC = 2,75, IC 95% 2,63­2,88) ou au Québec (39,1 %, RC = 3,42, IC 95% 3,27­3,58). En Ontario, 53,8 % des restaurants affichaient les calories pour > 90 % des produits, contre 23,0 % au Québec et 15,4 % en Alberta. La présence de l'affichage des calories différait également d'une plateforme à l'autre. CONCLUSION: L'information nutritionnelle sur les plateformes de SLRL différait entre les provinces disposant d'une réglementation sur l'affichage des calories et celles sans une telle réglementation. Les chaines de restaurants sur les plateformes de SLRL avaient davantage tendance à afficher les calories en Ontario, où ce type d'affichage est obligatoire, qu'ailleurs, où une telle politique est inexistante. D'une province à l'autre, l'affichage des calories n'a pas été mis en œuvre de manière uniforme sur les différentes plateformes de SLRL.

Study protocol for the Sino-Canadian Healthy Life Trajectories Initiative (SCHeLTI): a multicentre, cluster-randomised, parallel-group, superiority trial of a multifaceted community-family-mother-child intervention to prevent childhood overweight and obesity.

INTRODUCTION: Childhood overweight and obesity (OWO) is a primary global health challenge. Childhood OWO prevention is now a public health priority in China. The Sino-Canadian Healthy Life Trajectories Initiative (SCHeLTI), one of four trials being undertaken by the international HeLTI consortium, aims to evaluate the effectiveness of a multifaceted, community-family-mother-child intervention on childhood OWO and non-communicable diseases risk. METHODS AND ANALYSIS: This is a multicentre, cluster-randomised, controlled trial conducted in Shanghai, China. The unit of randomisation is the service area of Maternal Child Health Units (N=36). We will recruit 4500 women/partners/families in maternity and district level hospitals. Participants in the intervention group will receive a multifaceted, integrated package of health promotion interventions beginning in preconception or in the first trimester of pregnancy, continuing into infancy and early childhood. The intervention, which is centred on a modified motivational interviewing approach, will target early-life maternal and child risk factors for adiposity. Through the development of a biological specimen bank, we will study potential mechanisms underlying the effects of the intervention. The primary outcome for the trial is childhood OWO (body mass index for age ≥85th percentile) at 5 years of age, based on WHO sex-specific standards. The study has a power of 0.8 (α=0.05) to detect a 30% risk reduction in the proportion of children with OWO at 5 years of age, from 24.4% in the control group to 17% in the intervention group. Recruitment was launched on 30 August 2018 for the pilot study and 10 January 2019 for the formal study. ETHICS AND DISSEMINATION: The study has been approved by the Medical Research Ethics Committee of the International Peace Maternity and Child Health Hospital in Shanghai, China, and the Research Ethics Board of the Centre Intégré Universitaire de Santé et Services Sociaux de l'Estrie-CHUS in Sherbrooke, Canada. Data sharing policies are consistent with the governance policy of the HeLTI consortium and government legislation. TRIAL REGISTRATION NUMBER: ChiCTR1800017773. PROTOCOL VERSION: November 11, 2020 (Version #5).

Promoting Healthy Eating in Adults: An Evaluation of Pleasure-Oriented versus Health-Oriented Messages.

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.
