Using a Patient-Completed Food Frequency Questionnaire to Determine Mediterranean Diet Score in People with Inflammatory Bowel Disease.

Purpose: To examine the level of agreement between a patient-completed food frequency questionnaire (FFQ) and assessment of usual intake by a registered dietitian (RD) to score adherence to a Mediterranean diet (MedD) in patients with inflammatory bowel disease (IBD).Methods: Patients with IBD completed a short FFQ and were subsequently interviewed by an RD. A 12-item MedD score (MDS), adapted from the Mediterranean Diet Adherence Screener (MEDAS), was calculated from the FFQ and RD assessments. To determine agreement between individual items, Cohen's kappa coefficients were calculated. Absolute agreement between assessment methods was quantified using a one-way random intra-class correlation coefficient for a single measure.Results: Forty-six patients with IBD participated. The mean FFQ-MDS was 4.59 (standard deviation [SD] = 1.65), and mean RD-MDS was 4.83 (SD = 1.53). Kappa coefficients for individual MEDAS items ranged from 0.41 to 0.78 (p < 0.01) between the FFQ- and RD-MDS. Most items demonstrated moderate to substantial agreement. The intra-class correlation coefficient for absolute agreement between the summed FFQ-MDS and RD-MDS was 0.71 (95% confidence interval: 0.52-0.83, p < 0.001), indicating moderate reliability.Conclusions: This patient-completed FFQ may be a promising tool in clinical practice and research and would benefit from additional evaluation to validate its use in patients with IBD.

Weighted Gene Co-Expression Network Analysis Identifies a Functional Guild and Metabolite Cluster Mediating the Relationship between Mucosal Inflammation and Adherence to the Mediterranean Diet in Ulcerative Colitis.

Diet influences the pathogenesis and clinical course of inflammatory bowel disease (IBD). The Mediterranean diet (MD) is linked to reductions in inflammatory biomarkers and alterations in microbial taxa and metabolites associated with health. We aimed to identify features of the gut microbiome that mediate the relationship between the MD and fecal calprotectin (FCP) in ulcerative colitis (UC). Weighted gene co-expression network analysis (WGCNA) was used to identify modules of co-abundant microbial taxa and metabolites correlated with the MD and FCP. The features considered were gut microbial taxa, serum metabolites, dietary components, short-chain fatty acid and bile acid profiles in participants that experienced an increase (n = 13) or decrease in FCP (n = 16) over eight weeks. WGCNA revealed ten modules containing sixteen key features that acted as key mediators between the MD and FCP. Three taxa (Faecalibacterium prausnitzii, Dorea longicatena, Roseburia inulinivorans) and a cluster of four metabolites (benzyl alcohol, 3-hydroxyphenylacetate, 3-4-hydroxyphenylacetate and phenylacetate) demonstrated a strong mediating effect (ACME: -1.23, p = 0.004). This study identified a novel association between diet, inflammation and the gut microbiome, providing new insights into the underlying mechanisms of how a MD may influence IBD.

Gastroenterologist and Patient Attitudes Toward Yoga as a Therapy for Irritable Bowel Syndrome: An Application of the Theory of Planned Behaviour.

Objectives: To identify irritable bowel syndrome (IBS) patients' attitudes, subjective norms, perceived control and intention to practice yoga and gastroenterologists' attitudes and current yoga recommendations for their patients with IBS. Methods: Gastroenterologists and IBS patients completed online surveys including Theory of Planned Behaviour (TPB) constructs. Among IBS patients, multiple linear regression determined the multivariate associations between TPB variables and intention to practice yoga while controlling for significant socio-demographic variables. Gastroenterologists were asked about their attitudes and current yoga recommendations for patients with IBS. Chi-square analyses examined associations between gastroenterologists' demographics and recommending yoga. Binomial logistic regression described associations between attitude variables and current yoga recommendations. Results: For patients (n = 109), controllability (ß = 0.5, P < 0.001), affective attitude (ß = 0.4, P < 0.05) and self-efficacy (ß = 0.3, P < 0.05) were significantly associated with intention to do yoga in the regression model. TPB variables explained 34% of the variance in patients' intentions to practice yoga. The binomial regression analysis revealed that gastroenterologists (n = 79) who have confidence in recommending yoga (39%) were seven times more likely to recommend it (odds ratio = 7.3, P = 0.002) and those who agreed yoga improves IBS symptom severity (54%) were 10 times more likely to recommend yoga (odds ratio = 10.1, P < 0.001). Most (86%) wanted more evidence to support efficacy of yoga for IBS and 44% asked for more knowledge on how to refer a patient. Conclusion: Controllability, affective attitude and self-efficacy predicted IBS patients' intentions to practice yoga. Although gastroenterologists believed yoga is safe and beneficial for IBS patients, most do not recommend yoga due to lack of confidence and scientific evidence.

Crohn's disease therapeutic dietary intervention (CD-TDI): study protocol for a randomised controlled trial.

INTRODUCTION: Dietary patterns that might induce remission in patients with active Crohn's disease (CD) are of interest to patients, but studies are limited in the published literature. We aim to explore the efficacy of the CD therapeutic dietary intervention (CD-TDI), a novel dietary approach developed from best practices and current evidence, to induce clinical and biomarker remission in adult patients with active CD. METHODS AND ANALYSIS: This study is a 13-week, multicentre, randomised controlled trial in patients with mild-to-moderate active CD at baseline. One hundred and two patients will be block randomised, by sex, 2:1 to the intervention (CD-TDI) or conventional management. Coprimary outcomes are clinical and biomarker remission, defined as a Harvey Bradshaw Index of <5 and a faecal calprotectin of <250 µg/g, respectively.Secondary outcomes include gut microbiota diversity and composition, faecal short-chain fatty acids, regulatory macrophage function, serum and faecal metabolomics, C reactive protein, peripheral blood mononuclear cell gene expression profiles, quality of life, sedentary time and physical activity at 7 and/or 13 weeks. Predictive models of clinical response to a CD-TDI will be investigated. ETHICS AND DISSEMINATION: The research protocol was approved by the Conjoint Health Research Ethics Board at the University of Calgary (REB19-0402) and the Health Research Ethics Board-Biomedical Panel at the University of Alberta (Pro00090772). Study findings will be presented at national and international conferences, submitted for publication in abstracts and manuscripts, shared on social media and disseminated through patient-education materials. TRIAL REGISTRATION NUMBER: NCT04596566.

Evaluation of an integrated yoga program in patients with inflammatory bowel disease: A pilot study.

BACKGROUND: The effects of integrated yoga programs on mental health outcomes in inflammatory bowel disease (IBD) have not been well explored. To explore the acceptability, implementation and effectiveness of an integrated eight-week yoga program plus aromatherapy massage in patients with IBD. METHODS: Nine participants with documented IBD were recruited from a gastroenterology clinic in Calgary, Alberta, Canada to participate in an integrated yoga program weekly for eight weeks with outcomes assessed at baseline and week 8. Primary outcomes were assessed using Theory of Planned Behaviour as a guiding theory to identify salient beliefs from qualitative analysis of a semi-structured interview, survey items measuring the strength of beliefs and a daily log was used to capture adherence and adverse events. Secondary outcomes were collected using validated survey tools examining anxiety, depression, stress, sleep quality, and physical and mental quality of life. RESULTS: Attitude, subjective norm and perceived behavioral control beliefs pertinent to the yoga intervention and daily practice were identified. Participants reported feeling the intervention was very helpful; however, felt guilt about not completing daily practices which decreased confidence and intention to continue with the practice. An average of 55.6% of in-person sessions were attended and decreased over time. Participants practiced on average of 5.4 days per week. Depression and mental health scores improved at week 8 from baseline. CONCLUSIONS: We were able to identify key salient beliefs of IBD patients in regard to an integrated yoga plus aromatherapy massage intervention. This intervention appears to be acceptable and further research should explore its potential to improve mental and physical health outcomes including IBD symptoms.

The role of precision nutrition in the modulation of microbial composition and function in people with inflammatory bowel disease.

Inflammatory bowel diseases, principally Crohn's disease and ulcerative colitis, are multifactorial chronic conditions. Alterations in gut microbial patterns partly affect disease onset and severity. Moreover, the evolution of dietary patterns, and their effect on gut microbial behaviour, have been shown to play a crucial role in disease processes. This Viewpoint reviews the role of dietary patterns, their influence on the structure and function of the gut microbiome, and their effects on inflammation and immunity in individuals with inflammatory bowel disease. We also discuss innovative dietary intervention strategies, summarise findings that have been used to develop recommendations for clinical practice, and provide suggestions for the design of future studies for development of precision nutrition in patients with inflammatory bowel disease.

Dietary patterns, food groups and nutrients in Crohn's disease: associations with gut and systemic inflammation.

This study examined associations between dietary intake and gut and systemic inflammation assessed by fecal calprotectin ≤ or > 100 µg/mg (FCP), C-reactive protein ≤ or > 5 mg/L (CRP) and serum cytokine profiles in Crohn's disease (CD) patients in clinical remission. A 3-month observational study was conducted at the University of Calgary in Calgary, Alberta, Canada between 2016 and 2018 in 66 outpatients with CD in clinical remission. FCP was obtained from stool samples at baseline and 3-months and serum CRP and serum cytokines were assessed at 3-months only (n = 41). Dietary intakes were collected using 3-day food records at baseline and 3-months and categorized as: PREDIMED Mediterranean diet scores (pMDS) total and individual components, the dietary inflammatory index (DII), food groups, and common micro- and macro-nutrients. Statistical models were developed to identify relationships between dietary factors and FCP, CRP and cytokine levels. Daily intake of leafy green vegetables was associated with FCP ≤ 100 µg/mg (p < 0.05). Increasing omega 6:3 ratio was associated with CRP ≤ 5 mg/L (p = 0.02). Different cytokines were significantly associated with various dietary variables. Future studies in patients with greater disease activity should be undertaken to explore these relationships.

Using Patient Completed Screening Tools to Predict Risk of Malnutrition in Patients With Inflammatory Bowel Disease.

Background: Malnutrition is associated with adverse clinical outcomes in patients with inflammatory bowel disease (IBD), however, malnutrition screening is not routinely performed. This study aimed to identify the prevalence of malnutrition in patients with IBD and compare the accuracy of patient completed screens to a gold-standard malnutrition assessment tool: the dietitian-completed subjective global assessment (SGA). Methods: This cross-sectional study was conducted at 2 hospitals and 2 ambulatory care clinics in Alberta, Canada. Patients with IBD completed 4 malnutrition screening tools: abridged patient-generated SGA (abPG-SGA), Malnutrition Universal Screening Tool (MUST), Canadian Nutrition Screening Tool (CNST), and Saskatchewan IBD-nutrition risk (SaskIBD-NR). Risk of malnutrition was calculated for each tool and differences were compared between IBD subtype and body mass index (BMI) categories. Sensitivity and specificity, negative and positive predictive values (NPV and PPV), and area under the receiver operating characteristic curve (AUC) were calculated compared to SGA. Results: Patients with Crohn's disease (n = 149) and ulcerative colitis (n = 96) participated in this study. Overall prevalence of malnutrition using SGA was 23% and malnutrition risk for CNST, abPG-SGA, SaskIBD-NR, and MUST was 37%, 36%, 36%, and 27%, respectively. Overall, the abPG-SGA had the highest sensitivity (83%), PPV (53%), and NPV (94%), and largest AUC (0.837) compared to SGA. For patients with a BMI ≥25 kg/m2, sensitivity and PPV of the abPG-SGA decreased to 73% and 41%, respectively, with a AUC of 0.841. Conclusions: Malnutrition is prevalent in patients with IBD and using malnutrition risk screening tools such as the abPG-SGA may be useful to identify patients who would benefit from further assessment.

Yoga as a Therapy for Irritable Bowel Syndrome.

The aim of this state-of-the-art narrative review is to evaluate the current evidence about the effectiveness of yoga as therapy for IBS and explore its potential mechanisms of action. The current literature suggests yoga is effective and safe and may target multiple mechanisms involved in treatment of IBS. Evidence from randomized controlled trials identified yoga as more effective compared to pharmacological treatment and equally effective as dietary interventions or moderate-intensity walking. Improvements were seen in both physical health (IBS symptom severity, gastric motility, autonomic and somatic symptom scores, and physical functioning) and mental health outcomes (depression, anxiety, gastrointestinal-specific anxiety, and quality of life). Given favorable changes in IBS-related physical and mental health outcomes, preliminary data supports yoga as beneficial in this population. However, the relatively low-quality evidence resulting from heterogeneity of study designs, interventions, and outcome measures limit our ability to make specific recommendations about the use of yoga as therapy for patients with IBS.

Nutrition Center of Excellence (COE) in Inflammatory Bowel Disease-A Model and Rationale for Development.

GOALS: The goal of this study was to develop a multi-disciplinary consensus of nutrition care priorities for implementation in an IBD nutrition center of excellence (COE). BACKGROUND: The role for nutrition care in inflammatory bowel disease is broad and encompasses multiple domains. Gaps exist in the published literature around best nutrition care practices in inflammatory bowel disease and highlight the need for an evidence based approach acceptable to patients, and generalizable to a wide inflammatory bowel disease population. STUDY: Twelve health leaders in inflammatory bowel disease care attended a 1-day retreat. Two focus groups were completed using traditional focus group methodology for the first half of the retreat and a World Café method for the second half. Data analysis included review of analytic memos and conceptual analysis completed at the time of discussion, theme identification and team consensus for conceptual development. RESULTS: Three primary themes were identified as the main pillars of a COE in an IBD nutrition center of excellence. These include: a) excellence in clinical care, b) novel discovery and research, and c) knowledge translation to patients and practitioners. The key initial steps identified in this study included standardizing malnutrition screening and support while creating an environment where nutrition therapy is included as a standard of care, developing and examining the effectiveness of novel diet therapies, and translating knowledge to build capacity among care providers and patients. CONCLUSIONS: Using a 1-day retreat to identify a future direction for a center focused on nutrition excellence and align our coalition towards common goals was a successful strategy to develop consensus and identify nutrition care priorities for action.

Survey of Nutrition Practice in Patients with Severe Sepsis among Canadian Registered Dietitians.

PURPOSE: The purpose of this study was to determine the opinions and reported nutrition practices of Canadian Registered Dietitians (RDs) with regard to feeding patients with severe sepsis. METHODS: In 2017, surveys were sent to 112 eligible Canadian RDs in 10 provinces who were practicing in an intensive care environment. The survey included embedded branching logic questions developed to address major facets of sepsis, critical illness, and nutrition. The survey instrument assimilated all data in an anonymous manner, so respondents could not be linked to their answers. RESULTS: Of the 64 RDs who responded (57% response rate), the majority practiced in adult intensive care (81%), within an academic center (59%), and in a mixed unit (73%). A wide variability of Canadian RDs' opinions and practice was reported in determining energy requirements, enteral nutrition (EN) practice, EN with vasoactive agents, parenteral nutrition (PN), and supplemental micronutrients. CONCLUSIONS: Practice variability of Canadian RDs likely reflects gaps in both evidence and guidelines for severe sepsis. Further research efforts are needed to customize nutritional requirements in the patient with evolving sepsis, EN with patients at high risk for gastrointestinal dysfunction, optimizing PN, and the role of micronutrients.

Evaluation of a Patient Experience Tool in Dietetic Practice: Validation and Clinical Usage of the Assessment of Registered Dietitian Care Survey (ARCS).

Purpose: The study aim was to evaluate a patient experience survey, the Assessment of Registered Dietitian Care Survey (ARCS), that is aligned with a nutrition counselling approach (NCA) and evidence-based chronic disease care for use in outpatient registered dietitian (RD) practice. Methods: Criterion and construct validity were examined using Pearson correlation coefficients and principal components analyses, respectively. Reliability was examined using Pearson correlations and Cronbach's α. Acceptability was evaluated by survey response rate and readability. Kruskall-Wallis test was used to detect differences between RD scores. Results: A total of 479 survey packages were returned (46% response rate). Criterion validity indices were high (r = 0.91 and 0.94, P < 0.001) between Patient Assessment of Chronic Illness Care (PACIC) and NCA subscales, respectively, and lower with overall patient satisfaction (r = 0.63-0.65, P < 0.001). Construct validity revealed 2 factors for PACIC and NCA subscales. There was high internal reliability for the PACIC, 5As, and NCA (Cronbach's α > 0.7) and test-retest reliability showed an adequate consistency over time (r = 0.70, P < 0.05). The tool was able to detect differences in scores between RDs (P < 0.05). Conclusions: More research is warranted to explore ceiling effects and sensitivity to intervention in similar practice settings. The NCA subscale has acceptable reliability and validity to measure patient experience of RD care.

Evaluating the Evidence on Sitting, Smoking, and Health: Is Sitting Really the New Smoking?

Sitting has frequently been equated with smoking, with some sources even suggesting that smoking is safer than sitting. This commentary highlights how sitting and smoking are not comparable. The most recent meta-analysis of sedentary behavior and health outcomes reported a hazard ratio of 1.22 (95% confidence interval [CI] = 1.09, 1.41) for all-cause mortality. The relative risk (RR) of death from all causes among current smokers, compared with those who have never smoked, is 2.80 (95% CI = 2.72, 2.88) for men and 2.76 for women (95% CI = 2.69, 2.84). The risk is substantially higher for heavy smokers (> 40 cigarettes per day: RR = 4.08 [95% CI = 3.68, 4.52] for men, and 4.41 [95% CI = 3.70, 5.25] for women). These estimates correspond to absolute risk differences of more than 2000 excess deaths from any cause per 100 000 persons per year among the heaviest smokers compared with never smokers, versus 190 excess deaths per 100 000 persons per year when comparing people with the highest volume of sitting with the lowest. Conflicting or distorted information about health risks related to behavioral choices and environmental exposures can lead to confusion and public doubt with respect to health recommendations.

Walking and type 2 diabetes risk using CANRISK scores among older adults.

The objective of this study was to determine the association between pedometer-assessed steps and type 2 diabetes risk using the Public Health Agency of Canada-developed 16-item Canadian Diabetes Risk Questionnaire (CANRISK) among a large population-based sample of older adults across Alberta, Canada. To achieve our study objective, adults without type 2 diabetes (N = 689) aged 55 years and older provided demographic data and CANRISK scores through computer-assisted telephone interviews between September and November 2012. Respondents also wore a step pedometer over 3 consecutive days to estimate average daily steps. Logistic regression was used to assess the association between achieving 7500 steps/day and risk of diabetes (low vs. moderate and high). Overall, 41% were male, average age was 63.4 (SD 5.5) years, body mass index was 26.7 (SD 5.0) kg/m2, and participants averaged 5671 (SD 3529) steps/day. All respondents indicated they were capable of walking for at least 10 min unassisted. CANRISK scores ranged from 13-60, with 18% in the low-risk category (<21). After adjustment, those not achieving 7500 steps/day (n = 507) were more than twice as likely to belong to the higher risk categories for type 2 diabetes compared with those walking ≥7500 steps/day (n = 182) (73.6% vs. 26.4%; odds ratio: 2.37; 95% confidence interval: 1.58 - 3.57). Among older adults without diabetes, daily steps were strongly and inversely associated with diabetes risk using the CANRISK score. Walking remains an important modifiable risk factor target for type 2 diabetes and achieving at least 7500 steps/day may be a reasonable target for older adults.

Assessment of Registered Dietitians' Beliefs and Practices for a Nutrition Counselling Approach.

PURPOSE: This study describes registered dietitians' (RDs) perceptions and use of a nutrition counselling approach (NCA) as defined by the American Academy of Nutrition and Dietetics Nutrition Care Process terminology (NCPT). METHODS: A cross-sectional online survey was administered to approximately 500 RDs in Alberta, Canada. Items included demographics, job characteristics, perceived knowledge, competence, use of an NCA, training experience, and theory of planned behaviour salient beliefs. Descriptive analyses compared RDs who counselled "all or most" of their clients with those who counselled "some or none." Salient beliefs were analyzed using content analysis. RESULTS: Of the 349 RDs who completed the survey, 64.2% provided an NCA to "all or most" of their patients. RDs were supportive of using an NCA (mean = 8.7/10, SD = 1.9) and most RDs (84.5%) had received training on an NCA. Salient beliefs included advantages (e.g., improved behaviour change in patients) and disadvantages (e.g., inadequate time). Normative referents included colleagues (e.g., multidisciplinary team), managers, patients/clients, College of RDs of Alberta, and counsellors. The barriers and enablers were related to patients' situations, infrastructure, and RD supports. CONCLUSIONS: These results may enable decision makers to more effectively design and target training and implementation programs to improve RDs' NCA.

Correlates of General and Domain-Specific Sitting Time among Older Adults.

OBJECTIVE: We examined the correlates of sitting time in a population-based sample of older adults. METHODS: Adults >55 years of age (N = 1296; N = 515 employed; N = 781 unemployed) self-reported measures of demographic and health-related variables, and a measure of sitting time (ie, SIT-Q). RESULTS: Employed total sitting time (min/day) was positively associated with home Internet access (B = 71.2, 95% CI, 8.9 to 133.4, p = .025), body mass index (BMI) (kg/m(2); B = 7.0, 95% CI, 2.1 - 11.9, p = .005), and negatively associated with physical health (B = -2.3; 95% CI, -4.9 to 0.3, p = .013). Unemployed total sitting time was negatively associated with age (B per year = -3.0, 95% CI, -4.9 to -1.1, p = .002), and being male (B = -54.0, 95% CI, -86 .7 to -21.3, p = .001). Unemployed total sitting time was positively associated with Internet access (B = 54.1, 95% CI, 17.7 to 90.4, p = .004) and BMI (B = 4.1, 95% CI, .94 to 7.3, p = .011). CONCLUSIONS: Older adults reported low levels of sitting time. Different correlates emerged for the employed and unemployed samples across sitting domains.

Understanding physical activity in individuals with prediabetes: an application of social cognitive theory.

Despite well-documented evidence implicating physical activity (PA) in the prevention of type 2 diabetes, the overwhelming majority of individuals with prediabetes are not physically active enough. The purpose of this study was to investigate the applicability of the social cognitive theory (SCT) in understanding PA behaviour in individuals with prediabetes. Individuals with prediabetes (N = 232) completed a mailed questionnaire assessing demographics, self-reported PA (MET.min/wk) and SCT constructs for PA MET.min/wk. For PA MET.min/wk, scheduling and task efficacy both had significant effects on PA (ß = .30 and .22, respectively). Goal formation also had a direct effect on PA for scheduling, coping and task efficacy (ß = .20, .34 and .30, respectively). Task, coping and scheduling efficacy explained a significant portion of the variance in PA behaviour. Overall, SCT appears to have merit as a model for understanding PA in individuals with prediabetes. Further evaluative inquiry is needed to establish support for the use of the SCT as a framework for developing, implementing and evaluating PA behaviour change interventions in this population.

Examining the Promotion of Healthy Eating among Exercise Specialists: A Cross-sectional Study.

The aim of this cross-sectional study was to survey exercise specialists about nutrition counselling practices, their own dietary practices, and to identify potential relationships. An electronic survey was used to examine characteristics and strategies used for assessing and promoting healthy eating to clients. Exercise specialists (n = 94) were recruited through a public registry and through targeted advertising on 2 professional websites in Alberta, Canada. Eighty-five percent of respondents promoted healthy eating to clients. Confidence in assessing and promoting healthy eating was moderate to low. Those with more than 6 years of professional experience reported higher confidence compared with those with less than 1 year of experience in assessing healthy eating (P < 0.05) and promoting healthy eating (P < 0.01). Confidence was higher among those with more professional experience but who did not meet Canada's Food Guide recommendations (P < 0.05). Professional experience, personal dietary practices, and confidence are important characteristics when considering the assessment and promotion of healthy eating by exercise specialists. Promoting collaborative relationships between registered dietitians and exercise specialists would likely benefit exercise specialists when they are assessing and promoting healthy eating among their clients.

Utility of telephone survey methods in population-based health studies of older adults: an example from the Alberta Older Adult Health Behavior (ALERT) study.

BACKGROUND: Random digit dialing is often used in public health research initiatives to accrue and establish a study sample; however few studies have fully described the utility of this approach. The primary objective of this paper was to describe the implementation and utility of using random digit dialing and Computer Assisted Telephone Interviewing (CATI) for sampling, recruitment and data collection in a large population-based study of older adults [Alberta Older Adult Health Behavior (ALERT) study]. METHODS: Using random digit dialing, older adults (> = 55 years) completed health behavior and outcome and demographic measures via CATI. After completing the CATI, participants were invited to receive a step pedometer and waist circumference tape measure via mail to gather objectively derived ambulatory activity and waist circumference assessments. RESULTS: Overall, 36,000 telephone numbers were called of which 7,013 were deemed eligible for the study. Of those, 4,913 (70.1%) refused to participate in the study and 804 (11.4%) participants were not included due to a variety of call dispositions (e.g., difficult to reach, full quota for region). A total of 1,296 participants completed telephone interviews (18.5% of those eligible and 3.6% of all individuals approached). Overall, 22.8% of households did not have an age 55+ resident and 13.6% of individuals refused to participate, Average age was 66.5 years, and 43% were male. A total of 1,081 participants (83.4%) also submitted self-measured ambulatory activity (i.e., via step pedometer) and anthropometric data (i.e., waist circumference). With the exception of income (18.7%), the rate of missing data for demographics, health behaviors, and health measures was minimal (<1%). CONCLUSIONS: Older adults are willing to participate in telephone-based health surveys when randomly contacted. Researchers can use this information to evaluate the feasibility and the logistics of planned studies using a similar population and study design.

Food and physical activity behaviours of adults attending a prediabetes education class.

OBJECTIVES: The primary objective of this study was to examine food and physical activity behaviours of adults with prediabetes. METHODS: For this cross-sectional study, adults (aged >17 years) with prediabetes (n=1228) who attended a prediabetes education class were recruited. Participants self-administered an assessment of food and physical activity behaviours using the Food Behaviour Checklist and the Godin Leisure Time Exercise Questionnaire. Linear regression models were performed to identify significant relationships between food, physical activity, age, body mass index and food access variables. RESULTS: Participants were 35.8% men with a mean age of 57.7 years (SD 11.6) and 64.2% women with a mean age of 55.2 years (13.9). Neither group was consuming adequate fruits and vegetables (17.1% for men and 29.2% for women eating 5 or more servings a day) or meeting physical activity guidelines of 150 minutes (29.5% for men and 26.2% for women). Approximately 29.0% of the entire sample "always" consumed milk or soy products. Men reported higher saturated fat intakes than women. For the entire sample, 83.4% rated their diet quality as needing improvement, and most consumed sweetened beverages (71.1% of men and 50.9% of women). Many participants (88.5%) used nutrition facts panels to choose foods. Food behaviour subscales and physical activity were significantly associated with each other and with age, body mass index and food access (p<0.05). CONCLUSIONS: Overall, adults with prediabetes reported less than optimal food and physical activity behaviours. Evaluation of lifestyle behaviours using simple tools like the Food Behaviour Checklist and Godin Leisure Time Exercise Questionnaire can be helpful for program design, evaluation and delivery.
