A number of other studies have been conducted to verify the Mini Nutritional Assessment (MNA) or the MNA short form (MNA-SF) as a nutritional assessment/screening tool in various clinical settings or communities. However, there are few longitudinal studies using these tools to analyze which factors affect the incidence of deteriorating nutritional status. We tried to identify the factors associated with deterioration of MNA-SF status of nursing home residents during a 2-year period.
Participants were 392 people with a mean age of 84.3 in 12 nursing homes in Japan. The factors associated with deterioration in MNA-SF categories during the study period compared to stable/improved MNA-SF categories were identified.
At baseline, 19.9% of the participants were malnourished and 60.2% were at risk of malnutrition, according to the MNA-SF classification. After 2 years, 66.3% participants maintained and 6.1% participants improved their nutritional status according to the MNA-SF classification, while 27.6% showed deterioration in MNA-SF status. Stepwise logistic-regression procedure indicated that basic ADL impairment and hospitalization during the follow-up period were associated with declining MNA-SF status.
Poor basic ADL status and hospitalization during the follow-up period were associated with malnutrition and risk of malnutrition as assessed by MNA-SF of nursing homes residents during a 2-year period.
已经开展了多项其他研究，以验证微型营养评定法（MNA）或MNA简表（MNA-SF）作为各种临床环境或社区中的营养评定/筛查工具。然而，很少有纵向研究使用这些工具来分析哪些因素会影响营养状况恶化的发生率。我们试图确定与养老院居民在2年期间MNA-SF状况恶化相关的因素。
研究对象为日本12家养老院的392人，平均年龄84.3岁。确定了在研究期间与MNA-SF类别恶化相关的因素，并与稳定/改善的MNA-SF类别进行比较。
根据MNA-SF分类，在基线时，19.9%的参与者营养不良，60.2%的参与者存在营养不良风险。2年后，根据MNA-SF分类，66.3%的参与者维持了营养状况，6.1%的参与者营养状况得到改善，而27.6%的参与者MNA-SF状况恶化。逐步逻辑回归分析表明，随访期间的基本日常生活活动能力受损和住院与MNA-SF状况下降有关。
在2年期间，基本日常生活活动能力差和随访期间住院与养老院居民通过MNA-SF评估的营养不良及营养不良风险有关。
