Relationship Between Vital Signs, Hemoglobin Level and Iron Consumption Pattern With Learning Concentration

Abstract

This study aimed to determine the vital signs (pulse and respiratory rate), hemoglobin (Hb) levels and iron (Fe) consumption pattern, and to assess their correlation with learning concentration in adolescents. This cross-sectional study was conducted from June to September 2017. Thirty-five subjects were selected from students majoring Biology Education at Yogyakarta State University (UNY) using purposive sampling technique (aged 17-24 years old). Physical examination was performed to measure pulse and respiratory rate, while hemoglobin level was measured with easy touch hemoglobin meter. Iron consumption pattern was assessed with nutrient conversion table and food record (Indonesian Health Ministry guideline), alongside the nutrient survey program and Bourdon Wiersma study concentration test. Data were analyzed using Spearman Correlation Test. The results showed that: (1) normal pulse, respiration rate and blood pressure found in female subjects were approximately 84%, 40%, and 91,67%; whereas in male subjects were 90,01%, 55%, and 81,81%, respectively (2) 37% female subjects had Hb level of >12 mg/dl and 100% male subjects had >13 mg/dl (3) adequate iron consumption pattern according to the nutrition instruments used in this study was 96% in female and 90,01% in male (4) learning concentration results indicated that study concentration was 45,71% in middle and 54,29% in lower category. In conclusion, there is correlation between study concentration with vital signs, i.e. pulse and respiratory rate, as well as with iron consumption pattern, but not with blood pressure nor Hb blood levels.
