1273 Children's Blood Pressure and Food Intake

Abstract

Blood pressure (BP) in childhood often correlates with BP in adulthood. The knowledge in children's dietary influence on BP is limited.Aims: 1. - To analyse BP and different food groups consumption relationship. 2. - To determine food intake differences between children with normal or higher BP values (≥ 85th percentile). Methods: We enrolled 428 children, provided parent's consent. We measured BP: systolic (syst) and diastolic (diast), pulse pressure (PP), mean pressure (MP). A 7-days questionnaire provided diet information. Z-score BP values classified participants into two groups: High-BP (HBP) ≥ 1.03 (n: syst=46, diast=100), Normal-BP (NBP) < 1.03 (n: syst=382, diast=328).Results: - Age: 7.9±2.4 years. - Correlation's analysis (significant results, Pearson C): ZScoreBPsyst: milk (-0,150), eggs (0,101), sweetbeverages (-0,109), pastries(-0,143)ZScoreBPdiast: sweet-beverages lpar;-0,156), nuts (-0,107), chocolate (-0,108)PP: milk (-0,141), eggs (0,130), vegetables (-0,111), pastries (-0,097)PM: cheese (0,100), fried-food (0,101), sweetbeverages (-0,179), nuts (-0,107), pastries (-0,129), chocolate (-0,118) - Comparison of means showed significant differences: NBP-syst ate more weekly portions of milk (NBP 7.5 ± 3.3; HBP 5.9±3.3) and pulses (NBP 1.1±1.1; HBP 0.7±1); and less fried-food (NBP 2.5±2; HBP 3.3± 2.4).NBP-diast ate more weekly portions of pastries (NBP 4.4±3.4; HBP 3.7±3.4), chocolate-products (NBP 4.9±3.8; HBP 3.9±3.1), eggs (NBP 2.1±1.3; HBP 1.7±1.4), sweet-beverages (NBP 2.6±3.2; HBP 1.8±2.1), nuts (NBP 0.5±1; HBP 0.3± 0.6) and vegetables (NBP 16.1±7,4; HBP 14.4±6.8).Conclusions: - Some sort of food seems to have early influence in BP values. - Relationship between food and BP in childhood must be considered as protective cardiovascular risk factors.
