Effects of malnutrition and weight loss risk on quality of life of elderly group in Nanjing communites

  • Background The elderly is a group with high prevalence of chronic diseases and high risk of malnutriton. At present, more atenton has been paid to the nutritonal status and appette of patents than to community residents.

    Objective The purpose of this study is to understand the nutritional status and appetite of the elderly in Nanjing communities and to explore the relationships of quality of life with malnutriton and weight loss risk of the elderly.

    Methods From March 2017 to December 2017, data were collected in fve randomly selected community hospitals in Nanjing, where elderly residents who were aged 60 years and above and had routne physical examinaton took part in the study, and a total of 506 valid samples were obtained. The subjects were surveyed by questionnaires and investigated for anthropometric measurements. The risk of malnutriton was assessed by Mini-Nutritonal Assessment Short-Form (MNA-SF), the risk of weight loss was assessed by Short Nutritonal Assessment Questonnaire (SNAQ), and the quality of life was assessed by 36-Item Short Form Survey (SF-36). SPSS 22.0 sofware was used for statstcal analysis to compare the differences of life quality dimensions, physiological comprehensive measurement, and psychological comprehensive measurement of subjects with different risks of malnutriton and risks of weight loss. Stepwise linear regression analysis was adopted to evaluate the influencing factors of physiological and psychological comprehensive measurements.

    Results Among the 506 elderly subjects, the average age was (71.25±6.24) years; 5.9% (30/506) were malnourished, 35.8% (181/506) were at risk of malnutrition, and 30.0% (152/506) were at risk of weight loss. The total score of quality of life of the subjects was 72.58±11.36, the score of physiological comprehensive measurement was 72.62±11.43, and the score of psychological comprehensive measurement was 72.54±14.11. The elderly with higher educaton level and no risk of weight loss had higher scores of physiological comprehensive measurement (Ps < 0.05); those with older age, multiple chronic diseases, and malnutrition had lower scores of physiological comprehensive measurement (Ps < 0.001). The subjects with good nutrition had higher scores of psychological comprehensive measurement (P < 0.001); those with risk of weight loss and multple chronic diseases had lower scores of psychological comprehensive measurement (Ps < 0.001).

    Conclusion Malnutriton and loss of appette can affect the quality of life of the elderly.
