Social factors associated with changes in nutrition risk scores measured using SCREEN-8: data from the Canadian Longitudinal Study on Aging.

Purpose: To examine the social network factors associated with changes in nutrition risk scores, measured by SCREEN-8, over three years, in community-dwelling Canadians aged 45 years and older, using data from the Canadian Longitudinal Study on Aging (CLSA).Methods: Change in SCREEN-8 scores between the baseline and first follow-up waves of the CLSA was calculated by subtracting SCREEN-8 scores at follow-up from baseline scores. Multivariable linear regression was used to examine the factors associated with change in SCREEN-8 score.Results: The mean SCREEN-8 score at baseline was 38.7 (SD = 6.4), and the mean SCREEN-8 score at follow-up was 37.9 (SD = 6.6). The mean change in SCREEN-8 score was -0.90 (SD = 5.99). Higher levels of social participation (participation in community activities) were associated with increases in SCREEN-8 scores between baseline and follow-up, three years later.Conclusions: Dietitians should be aware that individuals with low levels of social participation may be at risk for having their nutritional status decrease over time and consideration should be given to screening them proactively for nutrition risk. Dietitians can develop and support programs aimed at combining food with social participation.

Improving Malnutrition Screening among Hemodialysis Patients.

Individuals receiving hemodialysis are at increased risk of malnutrition; however, regular diagnosis of malnutrition using subjective global assessment (SGA) is time-consuming. This study aimed to determine whether the Canadian Nutrition Screening Tool (CNST) or the Geriatric Nutrition Risk Index (GNRI) screening tools could accurately identify hemodialysis patients at risk for malnutrition. A retrospective medical chart review was conducted for in-centre day shift hemodialysis patients (n = 95) to obtain the results of the SGA assessment and the CNST screener and to calculate the GNRI score. Sensitivity and specificity analyses showed only a fair agreement between the SGA and CNST (sensitivity = 20%; specificity 96%; κ = .210 (95% CI, -0.015 to .435), p < .05) and between the SGA and GNRI (sensitivity = 35%; specificity = 88%; κ = .248 (95% CI, .017 to .479), p < .05). There was no significant statistical difference between the accuracy of either tool in identifying patients at risk of malnutrition (p = .50). The CNST and GNRI do not accurately screen for risk of malnutrition in the hemodialysis population; therefore, further studies are needed to determine an effective malnutrition screening tool in this population.

The Evidence for Screening Older Adults for Nutrition Risk in Primary Care: An Umbrella Review.

It is not known if nutrition risk screening of older adults should be a standard practice in primary care. The evidence in support of nutrition risk screening of older adults in primary care was examined and critically analyzed using an umbrella review. The peer reviewed and grey literature were searched for clinical practice guidelines (CPGs) and systematic reviews (SRs). Titles and abstracts were independently screened by the two authors. Resources were excluded if they did not apply to older adults, did not discuss nutrition/malnutrition risk screening, or were in settings other than primary care. Full texts were independently screened by both authors, resulting in the identification of six CPGs and three SRs that met the review criteria. Guidelines were appraised with the AGREE II tool and SRs with the AMSTAR 2 tool. The quality of the CPGs was high, while the quality of the SRs was low. The CPGs and SRs acknowledged a lack of high-quality research on the benefits of regular nutrition risk screening for older adults in primary care; however, CPGs recommended annual screening for older adults in primary care practices or other community settings. High-quality research investigating nutrition risk screening of older adults in primary care is needed.

Factors Associated with the Development of High Nutrition Risk: Data from the Canadian Longitudinal Study on Aging.

This study aimed to determine which social network, demographic, and health-indicator variables were able to predict the development of high nutrition risk in Canadian adults at midlife and beyond, using data from the Canadian Longitudinal Study on Aging. Multivariable binomial logistic regression was used to examine the predictors of the development of high nutrition risk at follow-up, 3 years after baseline. At baseline, 35.0 per cent of participants were at high nutrition risk and 42.2 per cent were at high risk at follow-up. Lower levels of social support, lower social participation, depression, and poor self-rated healthy aging were associated with the development of high nutrition risk at follow-up. Individuals showing these factors should be screened proactively for nutrition risk.

Community-Based Nutrition Risk Screening in Older Adults (COMRISK): An Exploration of the Experience of Being Screened and Prevalence of Nutrition Risk in Alberta, Canada.

The objectives of this feasibility study were to measure the prevalence of nutrition risk in community-dwelling older adults (CDOA, ages ≥ 65 years) and explore the perspectives of CDOA of the acceptability, value, and effectiveness of nutrition risk screening in primary care and community settings. Using the Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN)© eight-item tool (n = 276), results indicated that moderate and high nutrition risks affected 50 per cent and 8 per cent, respectively, of those screened. Interviewees (n = 16) agreed that screening is acceptable, important, and valuable (Theme One). Effectiveness was unclear, as only 3 of 16 respondents recalled being told their nutrition risk status. When articulating nutrition-related issues, a food security theme, expressed in the third person, was prominent (Theme Two). Screening for nutrition risk and receiving nutrition information in community-based settings are acceptable to CDOA and medically necessary, as evidenced by the high proportion of CDOA at moderate-high nutrition risk.

COMmunity-Based Nutrition RISK Screening in Older Adults Living Independently (COMRISK): Feasibility, Acceptability, and Appropriateness of Community Partnership Models in Alberta, Canada.

This feasibility study of routine nutrition risk screening in community-dwelling older adults using a partnership between health care and community-based organizations (CBO) aimed to (1) evaluate the ability of community-based partnerships to provide screening for nutrition risk, and appropriately refer at-risk individuals for follow-up care and (2) determine the barriers to and facilitators of screening. Adults 65 years of age and older were screened by staff in two primary care and one CBO setting using the Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN)-8 nutrition risk screening tool. Screeners, organization administrators, and registered dietitians responded to surveys regarding SCREEN-8 administration, referral processes, and partnership interactions. All found the SCREEN-8 initiative feasible, acceptable, and appropriate. Sustainability requires strengthening of community resources, referral processes, and telephone assessments. The partnership added value despite limitations in communications. We conclude that broader implementation of this program using community-based partnerships has the potential to aid in the prevention of malnutrition in older adults.

Malnutrition modifies the response to multimodal prehabilitation: a pooled analysis of prehabilitation trials.

Patients with colorectal cancer are at risk of malnutrition before surgery. Multimodal prehabilitation (nutrition, exercise, stress reduction) readies patients physically and mentally for their operation. However, it is unclear whether extent of malnutrition influences prehabilitation outcomes. We conducted a pooled analysis from five 4-week multimodal prehabilitation trials in colorectal cancer surgery (prehabilitation: n = 195; control: n = 71). Each patient's nutritional status was evaluated at baseline using the Patient-Generated Subjective Global Assessment (PG-SGA; higher score, greater need for treatment of malnutrition). Functional walking capacity was measured with the 6-minute walk test distance (6MWD) at baseline and before surgery. A multivariable mixed effects logistic regression model evaluated the potential modifying effect of PG-SGA on a clinically meaningful change of ≥19 m in 6MWD before surgery. Multimodal prehabilitation increased the odds by 3.4 times that colorectal cancer patients improved their 6MWD before surgery as compared with control (95% confidence interval (CI): 1.6 to 7.3; P = 0.001, n = 220). Nutritional status significantly modified this outcome (P = 0.007): Neither those patients with PG-SGA ≥9 (adjusted odds ratio: 1.3; 95% CI: 0.23 to 7.2, P = 0.771, n = 39) nor PG-SGA <4 (adjusted odds ratio: 1.3; 95% CI: 0.5 to 3.8, P = 0.574, n = 87) improved in 6MWD with prehabilitation. In conclusion, baseline nutritional status modifies prehabilitation effectiveness before colorectal cancer surgery. Patients with a PG-SGA score 4-8 appear to benefit most (physically) from 4 weeks of multimodal prehabilitation. Novelty: Nutritional status is an effect modifier of prehabilitation physical function outcomes. Patients with a PG-SGA score 4-8 benefited physically from 4 weeks of multimodal prehabilitation.

Greater Nutritional Risk Scores in 2-Year-Old Children Exposed to Gestational Diabetes Mellitus In Utero and Their Relationship to Homeostasis Model Assessment for Insulin Resistance at Age 5 Years.

OBJECTIVES: Exposure to gestational diabetes mellitus (GDM) in utero may impact nutritional intake and lifestyle habits in early childhood. However, it is unclear whether nutritional status predicts greater risk for metabolic disturbances, such as insulin resistance (IR). The primary objectives were: 1) to determine parent-reported nutritional risk scores in 2-year-old children born to women with and without GDM and 2) to assess whether these scores predict IR in 5-year-old children. METHODS: Children exposed (n=34) and unexposed (n=46) to GDM were screened at 2 years of age using the Toddler version of the Nutrition Screening Tool for Every Preschooler (NutriSTEP). At a 5-year follow up, IR was assessed using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). RESULTS: Total NutriSTEP scores ranged from 6 to 33, with higher scores indicating greater risk. After controlling for infant birthweight, sex of the child, child ethnicity, maternal age at time of pregnancy, breastfeeding status and maternal prepregnancy body mass index, average NutriSTEP scores were higher in children exposed to GDM compared with those unexposed (13.8±1.1 vs 11.2±1.1, p=0.03). NutriSTEP scores at 2 years emerged as a positive independent predictor of HOMA-IR at 5 years. For each unit increase in NutriSTEP score, suggesting greater nutritional risk, we saw a 0.48 (95% confidence interval, 0.17 to 0.80; p=0.003) increase in score on the HOMA-IR. CONCLUSIONS: Parent-reported nutritional risk is greater in GDM-exposed children, and these nutritional behaviours developed during the first years of life may predispose to metabolic disturbance in early childhood.

Building Nutrition into a Falls Risk Screening Program for Older Adults in Family Health Teams in North Eastern Ontario.

Approximately 30 per cent of those over the age of 65 living in the community fall at least once each year, and a similar proportion are at nutrition risk. Screening is an important component of prevention. The objective of this study was to understand how to add nutrition risk screening to a falls risk screening program in family health teams (FHTs). Interview participants (n = 31) were staff/management, regional representatives, and clients from six FHTs that had started integrating screening. Thematic analysis was conducted. Themes identified how to develop screening programs: setting up for successful screening, making it work, and following up with risk. An overarching theme recognized "it's about building relationships". Adding nutrition risk to a falls risk screening program takes effort, and is different for each FHT based on their work flow and client population. Determining how to integrate screening into the work flow and planning to address identified risk are necessary components.

Development, reliability, and validity testing of Toddler NutriSTEP: a nutrition risk screening questionnaire for children 18-35 months of age.

Nutrition is vital for optimal growth and development of young children. Nutrition risk screening can facilitate early intervention when followed by nutritional assessment and treatment. NutriSTEP (Nutrition Screening Tool for Every Preschooler) is a valid and reliable nutrition risk screening questionnaire for preschoolers (aged 3-5 years). A need was identified for a similar questionnaire for toddlers (aged 18-35 months). The purpose was to develop a reliable and valid Toddler NutriSTEP. Toddler NutriSTEP was developed in 4 phases. Content and face validity were determined with a literature review, parent focus groups (n = 6; 48 participants), and experts (n = 13) (phase A). A draft questionnaire was refined with key intercept interviews of 107 parents/caregivers (phase B). Test-retest reliability (phase C), based on intra-class correlations (ICC), Kappa (κ) statistics, and Wilcoxon tests was assessed with 133 parents/caregivers. Criterion validity (phase D) was assessed using Receiver Operating Characteristic (ROC) curves by comparing scores on the Toddler NutriSTEP to a comprehensive nutritional assessment of 200 toddlers with a registered dietitian (RD). The Toddler NutriSTEP was reliable between 2 administrations (ICC = 0.951, F = 20.53, p < 0.001); most questions had moderate (κ ≥ 0.6) or excellent (κ ≥ 0.8) agreement. Scores on the RD nutrition risk rating and the Toddler NutriSTEP were correlated (r = 0.67, p < 0.000). The area under the ROC curve for moderate and high RD risk ratings were 84.6% and 82.7%, respectively. Cut-points of ≥21 (sensitivity 86%; specificity 61%) (moderate risk) and ≥26 (sensitivity 95%; specificity 63%) (high risk) were determined. The Toddler NutriSTEP questionnaire is both reliable and valid for screening for nutritional risk in toddlers.
