Abstract：Objective To learn about the current situation of nutrition risk of the elderly patients with mild cognitive impairment (MCI) in Hunan Province, and to analyze the combined influence of each factor on nutrition risk. Methods By means of multistage sampling, 205 normal cognition residents (NC group) and 176 patients with MCI (MCI group) who met research requirements were selected from 5 cities in Hunan Province from October, 2014 to December, 2016. Their basic demographic information, cognitive level and nutrition risk were surveyed and the combined influence of the respondents’ basic situation and cognitive level on their nutrition risk was analyzed. Results For both NC group and MCI group, the survival of the respondents’ spouses, their living conditions, monthly income, type of medical insurance, career and occupation, sleep quality, social activities, exercise habit and pattern of diet all significantly influenced their Nutritional Risk Screening (NRS) 2002 score (all P<0.05). The Montreal Cognitive Assessment (MoCA, Changsha version) score (t=29.67,P=0.00) and NRS 2002 score (t=15.81,P=0.00) were significantly different between NC group and MCI group. MoCA score and NRS 2002 score were positively correlated both in NC group (r=0.56, P=0.00) and MCI group (r=0.73, P=0.00). The factors affecting nutrition risk of the patients in MCI group were pattern of diet (OR=10.80), cognitive level (OR=6.42), living style (OR=4.71), monthly income (OR=4.35), type of medical insurance (OR=3.86), sleep quality (OR=2.64) and exercise (OR=2.08). Conclusions Nutrition risk of the aged patients of with MCI is significantly higher than that of the normal cognition residents. Typically, the aged with irregular pattern of diet, low cognition level, lonely and solitary life, low monthly income and bad sleep quality as well as those without medical insurance or exercise should prevent the adverse effects of nutrition risk on their health.
