Modified Texture Food Use is Associated with Malnutrition in Long Term Care: An Analysis of Making the Most of Mealtimes (M3) Project.

OBJECTIVE: Modified texture food (MTF), especially pureed is associated with a high prevalence of under-nutrition and weight loss among older adults in long term care (LTC); however, this may be confounded by other factors such as dependence in eating. This study examined if the prescription of MTF as compared to regular texture food is associated with malnutrition risk in residents of LTC homes when diverse relevant resident and home-level covariates are considered. DESIGN: Making the Most of Mealtimes (M3) is a cross-sectional multi-site study. SETTING: 32 LTC homes in four Canadian provinces. PARTICIPANTS: Regular (n= 337) and modified texture food consumers (minced n= 139; pureed n= 68). MEASUREMENTS: Malnutrition risk was determined using the Mini Nutritional Assessment short-form (MNA-SF) score. The use of MTFs, and resident and site characteristics were identified from health records, observations, and standardized assessments. Hierarchical linear regression analyses, accounting for clustering, were performed to determine if the prescription of MTFs is associated with malnutrition risk while controlling for important covariates, such as eating assistance. RESULTS: Prescription of minced food [F(1, 382)=5.01, p=0.03], as well as pureed food [F(1, 279)=4.95, p=0.03], were both significantly associated with malnutrition risk among residents. After adjusting for age and sex, other significant covariates were: use of oral nutritional supplements, eating challenges (e.g., spitting food out of mouth), poor oral health, and cognitive impairment. CONCLUSIONS: Prescription of minced or pureed foods was significantly associated with the risk of malnutrition among residents living in LTC facilities while adjusting for other covariates. Further work needs to consider improving the nutrient density and sensory appeal of MTFs and target modifiable covariates.

Trajectories of Nutritional Risk: The Manitoba Follow-Up Study.

OBJECTIVES: To identify patterns of nutritional risk among older men over a four-year period and to project their survival rates over the next two and a half years. DESIGN: A prospective longitudinal study. SETTING: Canada. PARTICIPANTS: Three hundred and thirty-six male survivors of the Manitoba Follow-up Study (MFUS) cohort with an average age of 90 years in 2011. MEASUREMENTS: Four years of nutritional risk SCREEN II scores (five waves) from the male survivors of the MFUS cohort. The semi-parametric group-based trajectory approach and survival analysis were used to investigate the trajectories of nutritional risk. RESULTS: Of the participants, 30% lived alone. Five distinct developmental trajectory groups for nutritional risk score were identified. Significant statistical differences were found among the five trajectory groups for SF-36 mental health (p=.02), SF-36 physical health (p=<.001), perception of aging successfully (p=.04) and living alone (p=<.001). Among the five groups, the most pairwise differences were found in appetite, intake of meat and alternatives, and vegetables and fruit, weight change, skipping meals and eating with others. Men in the poorest nutritional risk trajectory group were two times more likely to die within a 2 1/2 year period compared to men in the best nutritional risk trajectory group (hazard rate = 2.33, p=.07). CONCLUSION: Distinct nutritional risk trajectories were found for older men over a four year period. Poor nutritional risk trajectories are associated with higher risk of mortality for very old men over a short period of time. Timely nutritional assessments by health professionals are needed to identify older men at nutritional risk. Subsequent nutrition education and follow-up may be important in preventing further decline.

Food group consumption and self-rated diets of elderly community-dwelling canadian men. The manitoba followup study.

BACKGROUND: Healthy eating perceptions and food group consumption practices of elderly men are largely unexplored. Understanding eating practices of elderly men and how this relates to their quality of life is important for the implementation of practical health promotion strategies. OBJECTIVE: Examine the frequency of food items consumed (daily, most days, or rarely), and the association of self-rated diet and food group consumption of elderly community-dwelling Canadian men. DESIGN: Self-reported nutrition data, obtained via mailed questionnaires in spring 2000, from 1,211 Canadian male respondents (mean age 82 years) participating in the Manitoba Follow-up Study were analyzed. RESULTS: Respondents consumed vegetables/fruit (64%) and grain products (58%) daily, and meat/alternatives (81%) most days. Milk products were equally consumed daily (47%) or most days (47%). Using multiple logistic regression models, controlling for demographic variables, a positive relationship was found between the increasing consumption of vegetables/fruit and grain products and healthier self-rated diets. Daily consumption of vegetables/fruit or grain products significantly predicted healthier self-rated diets compared to men consuming those food categories most days, OR=2.42 (95%CI=1.88, 3.11) and OR=2.18 (95%CI=1.70, 2.79), respectively. Those consuming meat/alternatives or milk products "daily" or "rarely" rated their diets as healthier than those consuming these items "most days". CONCLUSION: Daily consumption of fruits, vegetables, and grain products is viewed as important for overall health and is positively associated with healthier self-rated diets among elderly Canadian men.
