- Abstract
The aim of this study is to determine whether there is a significant relationship between certain insomnia symptoms and drinking water shortly before bedtime as seen anecdotally in a clinical setting. A survey was done of 1223 patients receiving standard physical exams at a large hospital in Taiwan. Every patient was asked whether they were willing to answer a series of questions; if they agreed, they were given the questionnaire. Information in questionnaire form was gathered concerning demographic information and about pre-bedtime lifestyle habits of the respondents, including whether they drank specified beverages. Analysis of the data revealed three discrete classes based on the degree of their insomnia symptoms: Group 1, Group 2, and Group 3. From the multivariate logistic regression mode, Group 2 and Group 3 show a higher proportion of beverage-drinking behavior of study participants before going to bed than Group 1. Group 3 and Group 2 have ORs of 1.59 (P < 0.05) and 1.78 (P < 0.01), respectively. Further, females have higher rates of Group 2 at 1.49 times those of Group 1 (P < 0.05). In terms of age, younger participants have higher degrees of being in Group 3, compared to Group 1; the age groups of 45–64 and above 65 show ORs of 0.45 (P < 0.001) and 0.11 (P < 0.001). Most participants in Group 2 are in the 45–64 and above 65 age cohorts (OR 1.69, P < 0.05). Finally, most participants without regular exercise are in Group 3 (OR 1.53, P < 0.05). Scant research has been done in the area of insomnia and ingestion of fluids shortly before bed. The findings in this study offer some of the first evidence revealing a significant relationship between sleep disorder symptoms and beverage drinking before bedtime; consequently, it can be the impetus for further research in this field as an aid to personal and public health.
