• Resumen

  • Introduction: Proper hydration is important for maintaining homeostasis in all physiological processes and avoid some diseases. Cardiovascular risk factors (CVRF) are more common in the young population.

    Objective: To analyze water intake of Mexican adolescents according to the presence of CVRF.

    Method: A cross sectional study including adolescents was conducted in Mexico City; anthropometric measurements (weight, height and waist circumference) were taken, as well as blood pressure according to AHA recommendations to evaluate hypertension. A 24h recall was obtained and analyzed with the Food Processor Software. Body mass index (BMI) was calculated and subjects were classified as overweight / obese (OW-O) according to CDC percentiles.

    Results: 242 adolescents were evaluated; the average age was 12±1.9 years, 50.4% of the sample were boys. A global prevalence of hypertension was of 15%. 43.4% was classified as OW-O meanwhile only 27% presented abdominal obesity (AO) according to waist circumference. The daily intake of water, including foods, was 1263.1±656 ml with a higher consumption in those with a normal weight compared with OW-O (1,555±605.2 vs 891.4±468.7 ml, respectively; p<0.05). No differences between those with normal blood pressure and hypertension were found (1,327±693.4 vs 1,265±644.6 ml, respectively; p>0.05). Also, the water intake was similar in those without AO in contrast with those with OA (1,350.5±727.8 vs 1,236±545 ml; p=0.254).

    Conclusion: There is a high prevalence of CVRF among Mexican adolescents. Low water consumption was reported in this population and it seems to be related to overweight and obesity but not to hypertension or abdominal obesity.
