Both insomnia and malnutrition are quite common and can cause similar negative consequences, such as falls, depression, and cognitive impairment in older adults, but there is no study investigating the relationship between the 2. The aims were to investigate relationships between insomnia/insomnia severity and Mini Nutritional Assessment (MNA) score and serum nutrient levels.
Setting and participants:
Aged 65 years or older, 575 outpatients were included.
Methods:
MNA scores >23.5, 17-23.5, and <17 were categorized as normal nutritional status, malnutrition risk, and malnutrition, respectively. Serum vitamin B12, vitamin D, and folate deficiencies were also evaluated. Insomnia Severity Index (ISI) with scores of 8 and higher indicated insomnia, which was further stratified as mild (8-14), moderate (15-21), or severe (22-28).
Results:
The mean age was 73.1 ± 7.7 years, with 73.2% being female. The prevalence of patients with no insomnia, mild insomnia, moderate insomnia, and severe insomnia were 34.4%, 20.9%, 30.1%, and 14.6%, respectively. After adjusting for gender, education, number of drugs, Charlson Comorbidity Index, presence of depression, and Mini-Mental State Examination scores, patients with insomnia had lower MNA scores than those without insomnia (OR = 0.84, 95% CI: 0.7-0.9, P < .001). There were significant relationships between moderate/severe insomnia and the presence of malnutrition and risk of malnutrition (OR = 1.6, 95% CI: 1.0-2.5, P = .046; OR = 1.6, 95% CI: 1.0-2.7, P = .042) and MNA scores (OR = 0.83, 95% CI: 0.7-0.9, P < .001)/OR = 0.82, 95% CI: 0.7-0.9, P < .001). There was no significant difference between insomnia severity status and serum vitamin D, vitamin B12, folate levels, or classification of these nutrients (P > .05).
Conclusions/Implications:
There is a close relationship between MNA scores and insomnia or insomnia severity in older adults. Therefore, when evaluating an older patient with insomnia, malnutrition should be evaluated, or insomnia should also be questioned in an older patient with malnutrition. Thus, more effective management of the 2 can be possible.
