Previous studies suggest those that maintain euhydration exhibit improved exercise and diet. However, limited data support a strong relationship between fluid intake behaviors and other health habits. PURPOSE: Examine potential relationships between caloric intake, health habits, and fluid intake. METHODS: Ninety-five participants (59 female, 36 male; 27 ± 10y, 72.2 ± 14.4kg) completed a validated electronic hydration survey evaluating hydration facilitators and behaviors. Researchers recorded body mass and height, and calculated BMI. Following survey administration, participants recorded total food and fluid intake for 24h. Diet logs were entered and analyzed via nutrition software (Nutritionist Pro). Previously identified themes for hydration facilitators and barriers were scored: lack of effort (LOE), physical barrier (PHB), lack of container (LOC), social facilitator (SOC), and monitoring facilitator (MOF). Data were analyzed using bivariate correlations and crosstab analyses, where appropriate (SPSS, v.28). RESULTS: Total fluids consumed (TFC; 3377.6 ± 1710.6mL) were significantly correlated with total Calories consumed (2170 ± 1059 Calories; TCC; r= .428; p<.01) and MOF (r= .266; p<.05). TFC were not significantly correlated with other survey variables (p>.05). The fluid behavior index was significantly correlated with LOE (r= -.674; p<.01), LOC (r= -.570; p<.01), SOC (r= -.300; p<.01) and MOF (r= .387; p<.01). Participants with decreased LOE (LR+ 90% CI: 1.1-2.3) and decreased LOC (LR+ 90% CI: 1.1-2.4) barriers were 1.6 times more likely to meet the Institute of Medicine recommended fluid intake. Those with decreased PHB were 1.4 times more likely to meet fluid guidelines (LR+ 90% CI: 0.8-2.6). Participants with an increased MOF were 1.5 times more likely to meet recommended fluid intake (LR+ 90% CI: 1-2.2). Participants who had greater FBI scores (5-7) were 1.2 times more likely to meet fluid guidelines (LR+ 90% CI: 1-1.6) than those with lower scores. There was no relationship between BMI and TFC (LR+: 1.1; 90% CI: 0.771-1.57). CONCLUSION: Limited relationships exist between fluid intake facilitators and barriers and hydration behaviors. LOE and LOC may be the strongest barriers to meeting fluid guidelines. As expected, TCC may relate to fluid intake, but this relationship is limited.
