Objectives: We hypothesized that parents' fluid intake habits and hydration status impacts children's drinking behavior and hydration status.

Methods: Healthy parents (18 y or older) and their children (3-13 y) (N = 729 pairs) were recruited from Northwest Arkansas and Phoenix, Arizona. Data collection occurred from Saturday morning through Monday morning. Diet was tracked with a food diary, and fluid ingestion was recorded using the validated Liq.In questionnaire. Parents and their children collected all urine voids in separate containers, beginning with the second urine void on Sunday and ending with the first on Monday. Parents were majority female (69%), white (712%), married (82%), and varied in income, education, and BMI status. Children were majority white (62%) and had normal BMI status (74%), with slightly more males (54%) than females (46%).

Results: There was a positive association between children’s and parent’s 24-h urine osmolality (β = 0.170, P < 0.001), SSB intake (β = 0.321, P < 0.001), total water intake (TWI (β = 0.18, P < 0.001), and plain water intake (PWI (β = 0.277, P < 0.001). Compared to children whose parents were adequately hydrated, children whose parents were underhydrated were 1.4 times more likely to be underhydrated (95% CI 1.11, 1.75, P = 0.009). Specific to children’s variables, older age (β = 0.341, P < 0.001), higher BMI (β = 0.126, P = 0.0004), greater physical activity (β = 0.064, P = 0.034), higher energy intake (β = 0.168, P < 0.003), higher protein intake (β = 0.175, P < 0.001) and male sex (β = 0.102, P < 0.001) were related to greater TWI in children. Specific to parental variables, higher PWI (β = 0.116, P = 0.046), higher TWI from fluids (TWI-f) (β = 0.097, P = 0.007), and higher BMI (β = 0.077, P = 0.018) were related to higher TWI in children.

Conclusions: Parents’ PWI and TWI-f are positively associated with children’s TWI, suggesting parents' hydration habits affect their children. Parents should know what they eat and drink since children may emulate their habits.
