Abstract

Introduction: Water, as one of the most essential nutrients, is involved in almost all biochemical processes of the human body. Although different degrees of dehydration have various symptoms such as physical and mental decline, severe dehydration is associated with decreased survival capacity in the physiological environment of the body that can put individuals, especially the elderly, at the risk of death. The present study aimed to determine the status of fluid intake and its association with cognitive impairments in the elderly people of Naein City in 2018.

Methods: This cross-sectional study was conducted among 225 randomly selected elderlies in Naein City. Data collection tools included demographic questionnaire, Mini–Mental State Examination, and 24-hour food recall questionnaire. The obtained data were analyzed using ANOVA, t-test and chi-square via SPSS software.

Results: The mean of total fluid intake was 2637.05 ± 772.35 ml / day. Among 225 participants, 36.4%, 37.3%, and 26.2% had normal, mild, and moderate cognitive impairment, respectively. Cognitive impairment had a significant relationship with gender, occupational status, level of education, marital status, and place of residence (p < 0.05). No significant relationship was observed between the mean of water consumption and cognitive impairment (p = 0.6).

Conclusion: The amount of fluid intake in elderly people living in Naein City was at a satisfactory level. Since no significant relationship was observed between the amount of fluid intake and cognitive impairments and more than half of the participants had cognitive impairments, we hypothesize that other factors are involved in prevalent of cognitive impairment.
