Hydration Status and Cognitive Performance in Adolescents (SMARTH2O)

Brief Summary:

Objective: to evaluate hydration status and his impact on cognitive performance in adolescents-based cohort study.

Methods: A randomized controlled pilot study is active in ten classes of one middle school (n=214 adolescents aged 12-14; including dismissed students) in an urban area around Milan, five classes being assigned to the intervention group and five classes to the control group. The five school-months intervention (from January to May 2018) includes changes in class environment (water dispenser to refill constantly, re-usable water bottles and educational posters about water consumption) and individual reinforcement tools (text messages and school lessons). The main endpoint is going to be the hydration status with osmolality urine test (dehydration status≥800 mOsm/kg). The secondary endpoint is going to be the correlation between the hydration status and cognitive performance (attention, short-term memory and concentration) through administration of neuropsychological tests from Neuropsychological Assessment Battery for Adolescence (BVN 12-18).

Results: it is expected an improvement of hydration status in intervention group versus control group and positive effects of a correct hydration on cognitive performance.

Arm Intervention/treatment
Experimental: Intervention group
Students of 5 secondary school classes aged 12-14
Behavioral: Intervention group
Refillable water dispensers will be placed in each class of the intervention group to facilitate water access: every class will receive 5 bottles (18 Liters/each) per week for a total of 5 months. Every student will receive a re-usable water bottle.

No Intervention: Control group
Students of 5 secondary school classes aged 12-14

Primary Outcome Measures :
  1. Hydration status [ Time Frame: Five months. From January to May. ]
    The hydration status is measured through urinary osmolality test, which indicates the solute concentration to kilograms solvent ratio (mOsm/kg): a value over 800 mOsm / kg indicates dehydration status, a value lower than 800 mOsm / kg indicates normal hydration status.

Secondary Outcome Measures :
  1. Cognitive performance [ Time Frame: Five months. From January to May. ]
    Correlation and the variation between hydration status and cognitive performances (attention, memory and concentration).
