Special Issue Information

Dear Colleagues,

Diet and nutrition have been identified as the cornerstone of diabetes and obesity management and are key in preventing and managing multiple chronic diseases. Indeed, diet and nutrition are vital for health, as they impact both physical and mental health, therefore having a large influence on quality of life in individuals that needs to be better understood.

This Special Issue will gather the latest evidence on “The Role of Diet and Nutrition in Chronic Disease Prevention and Management” and point to knowledge gaps requiring further investigation.

This special issue will encompass various types of manuscripts such as integrative reviews, scoping reviews, systematic reviews, umbrella reviews, descriptive studies, observational studies, and experimental studies, including those with quantitative, qualitative, and mixed methodologies.

Research topics may include, but are not limited to, research from around the world on how diet and nutrition impact the prevention and/or management of chronic diseases (such as obesity, type 2 diabetes, gestational diabetes, and other chronic diseases) and how this affects individuals’ physical health, mental health, and quality of life throughout the human life cycle.

I look forward to receiving your contributions.

Prof. Dr. Isabelle Giroux
Guest Editor

Background/Objectives: The sanitary measures implemented during the COVID-19 pandemic, although essential for limiting the virus propagation, hindered healthy behaviours and negatively affected mental health and quality of life. In immunosuppressed individuals at higher risk of COVID-19 complications, these measures may have influenced adherence to Canada’s Food Guide 2019 (CFG-2019). This study aims to describe whether changes in eating behaviours and food consumption during the COVID-19 pandemic were aligned with CFG-2019 and identify correlates of changes in immunosuppressed individuals and their relatives. Methods: A total of 210 participants completed an online questionnaire between May and September 2021. Changes in eating behaviours and food consumption were categorized as no change, change aligned with CFG-2019, or change not aligned. Multinomial logistic regressions examined the association between sociodemographic, lifestyle, clinical, and psychosocial characteristics and changes in eating behaviours and food consumption. Results: Participants reporting no change in eating behaviours, change aligned, and change not aligned with CFG-2019 were nearly equivalent (29.4%, 33.8%, and 36.8%, respectively). For food consumption, the proportions were 17.0%, 41.2%, and 41.8%, respectively. Reduced physical activity and elevated anxiety and depressive symptoms were associated with a change in eating behaviours not aligned with CFG-2019. Perceived weight gain and decreased body image satisfaction were associated with a non-aligned change in food consumption. Conclusions: Dietary changes, aligned or not with CFG-2019, were observed among immunosuppressed individuals and their relatives during the COVID-19 pandemic. Identifying factors associated with these changes can inform future studies to support healthy eating among vulnerable individuals amidst stressful events such as the COVID-19 pandemic. Full article

Background/Objectives: Canada’s Food Guide 2019 includes advice such as “Cook more often” and “Eat meals with others”, which are considered healthy eating practices. However, mothers with a history of gestational diabetes mellitus (GDM) may face specific barriers to adopting healthy eating practices. This study aimed to compare eating practices between mothers with (GDM+) and without (GDM−) a history of GDM, and to explore the associations between eating practices, diet quality, and the anthropometric and cardiometabolic profile of these mothers. Methods: The cross-sectional study was conducted in Quebec (Canada) between 2012 and 2017. Eating practices were assessed using a self-administered questionnaire. Diet quality was evaluated by the Healthy Eating Food Index 2019 through a validated food frequency questionnaire. Weight, height, and waist circumference were measured, and body composition was obtained by absorptiometry. Results: Data from 105 GDM+ and 38 GDM− mothers were analyzed (mean age 37.5 years ± 4.9). GDM+ mothers were more likely to prepare a greater proportion of dinners (≥1 per week) using pre-prepared or processed foods than GDM− mothers (49.0% vs. 34.2%; p = 0.016). Among GDM+ mothers, those who prepared ≥1 dinners per week using pre-prepared or processed foods showed lower adherence to the “Whole-grain foods” (1.1 ± 0.8 vs. 1.9 ± 1.2; p = 0.002) and “Sodium” (4.9 ± 2.0 vs. 5.8 ± 2.0, p = 0.013) recommendations, had a higher percentage of total body fat (37.5% ± 7.6 vs. 34.0% ± 7.7; p = 0.041), a higher waist circumference (91.6 cm ± 13.9 vs. 87.1 cm ± 16.3; p = 0.030), and a higher glycated hemoglobin (5.6% ± 0.5 vs. 5.5% ± 0.3; p = 0.025) than those who used less pre-prepared or processed foods. Conclusions: GDM+ mothers were more likely than GDM− mothers to prepare dinners using pre-prepared or processed foods, an eating practice associated with less favorable components of diet quality and some altered anthropometric and cardiometabolic variables. Further investigation into the factors influencing cooking from scratch within this population is warranted. Full article

Background: Gestational diabetes mellitus (GDM) is a type of diabetes diagnosed during pregnancy and its prevalence is on the rise around the world. GDM increases the risk of serious adverse health outcomes for the mother and child. Multiple types of non-pharmacological interventions have been developed for the management and prevention of GDM; however, there is a lack of clarity regarding their effectiveness. Objective: To summarize the evidence on the efficacy of non-pharmacological interventions in the management and prevention of GDM. Methods: For this integrative review, a comprehensive literature search was conducted in the databases MEDLINE, CINAHL, Embase, Scopus, and Web of Science. The methodology followed the integrative approach outlined by Whittemore and Knafl’s, and study quality was evaluated using the Mixed Methods Assessment Tool. Results: A total of 44 relevant studies were included. Key themes identified for GDM management were (1) nutrition therapy and physical activity, (2) social and psychological support, (3) digital tools, and (4) barriers and facilitators. For GDM prevention, themes were categorized into individual-level approaches, (5) lifestyle and supplements, and population-level approaches: (6) environmental factors, and (7) health in all policies. Conclusions: The growing prevalence of GDM is a major public health concern that requires the implementation of effective multi-level evidence-based strategies. Environmental, socioeconomic, and racial determinants of health have substantial impacts on GDM, highlighting the need to address the root causes of the illness. Further research is needed to support effective preventive and management measures beyond standard pharmacological treatment, so that evidence-based solutions can be applied to enhance and safeguard the health of current and future generations.
