Risk factor analysis of insufficient fluid intake among urban adults in Wuxi, China: a classification and regression tree analysis.


ABSTRACT: BACKGROUND:Dehydration due to insufficient fluid intake (IFI) is detrimental to health. This cross-sectional study aimed to assess the fluid intake of urban adults in Wuxi, China, and to identify potential risk factors contributing to IFI. METHODS:Adults were selected from the urban area of Wuxi, China, using a multiple-stage random sampling method. The fluid intake information was obtained with a 24-h self-reported diary over seven consecutive days in both summer and winter of 2015. A classification and regression tree (CART) analysis was conducted to detect the potential risk factors associated with IFI. CART is a machine-learning algorithm that portions the data into subsets by threshold. RESULTS:A total of 584 adults aged 18-87?years were included. The results showed that the median (P25-P75) values of daily fluid intake of the participants were 1100 (800-1550) mL in summer and 1000 (750-1300) mL in winter. Women had a higher prevalence of IFI than men in both summer (odds ratio (OR)?=?2.683, 95% confidence interval (CI): 1.830-3.934) and winter (OR?=?2.636, 95% CI: 1.677-4.142). The results of CART analysis showed that, in summer, BMI?
