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.
Making the Most of Mealtimes (M3) is a cross-sectional multi-site study.
32 LTC homes in four Canadian provinces.
Regular (n= 337) and modified texture food consumers (minced n= 139; pureed n= 68).
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.
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.
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.
改良质地食物(MTF),特别是泥状食物,与长期护理(LTC)机构中老年人营养不足和体重减轻的高发病率有关;然而,这可能与其他因素(如进食依赖)混淆。本研究在考虑了各种相关的居民和家庭层面的协变量后,考察了当 MTF 与常规质地食物相比时,MTF 的处方是否与 LTC 居民的营养不良风险相关。
充分利用用餐时间(M3)是一项横断面多地点研究。
加拿大四个省的 32 个 LTC 住宅。
常规质地食物(n=337)和改良质地食物消费者(切碎 n=139;泥状 n=68)。
使用迷你营养评估简短形式(MNA-SF)评分确定营养不良风险。MTF 的使用以及居民和地点特征是从健康记录、观察和标准化评估中确定的。在控制重要协变量(如进食辅助)的情况下,使用分层线性回归分析来确定 MTF 处方是否与营养不良风险相关。
切碎食物的处方[F(1,382)=5.01,p=0.03],以及泥状食物的处方[F(1,279)=4.95,p=0.03],都与居民的营养不良风险显著相关。在调整年龄和性别后,其他重要的协变量包括:口服营养补充剂的使用、进食挑战(例如,将食物从口中吐出)、口腔健康状况差和认知障碍。
在调整其他协变量后,处方使用切碎或泥状食物与 LTC 设施居民的营养不良风险显著相关。需要进一步研究如何提高 MTF 的营养密度和感官吸引力,并针对可改变的协变量进行干预。
