Abstract

Background: Postural Orthostatic Tachycardia Syndrome (POTS) is illness manifestations caused by autonomic dysfunction. Subjects with POTS predominantly are young women between 20-40 year old and most of them are college student. Exercise has proven can improve the function of body systems. College studentss time is mostly for academic activity and not much time for exercise. The main aim of this research was to know the association between exercise activity and the incidence of POTS in female college students. Method: This research was an analytical observational using case-control design approach. Samples were fifty eight female college students with POTS (16-23 years old) selected using purposive sampling. This study was done from November to December 2014 at Medical School of Sebelas Maret University Surakarta. Data of Exercise activity were obtained by questionnaire. Diagnosis of POTS was conducted by measuring heart rate using pulsemeter on Active Stand Test (AST) position while orthostatic symptoms were gotten by interview. Data were analyzed using Chi-Square test. Result: This study showed that most of the subjects with POTS (27.6%) had lower exercise activity than those without POTS (37.9%). The result of Chi Square analysis was p = 0.007. Conclusion: There was significant association between exercise activity and the incidence of POTS in female college students. Keywords: exercise activity, heart rate, POTS

Abstract

Introduction: Measurement of hemoglobin concentration can be done by hematology analyzer (HA) cyanmethemoglobin method (gold standard) and point-of-care testing (POCT) electrode-based biosensor method. POCT electrode-based biosensor method is one of the hemoglobin POCT and has not been studied before in Indonesia. This study examined the difference and correlation hemoglobin concentration by HA cyanmethemoglobin method and POCT electrode-based biosensor method. Methods: This was a cross sectional study in 4 senior high schools of Sukoharjo in Indonesia on Desember, 2016. Senior high schools were selected using a simple random sampling and senior high schools grade selected using a stratified random sampling. Among 173 grade 10 and 11 senior high school girls in this study the capillary and venous blood samples were collected. Capillary blood sample collected was immediately processed to measure the hemoglobin concentration using POCT electrode-based biosensor method and venous blood sample was collected to measure the hemoglobin concentration using HA cyanmethemoglobin method. Statistical analyses used were Mann-Whitney and Spearmans correlation coefficient (?=0.05). Results: Hemoglobin concentration determined by the POCT electrode-based biosensor method compared to HA cyanmethemoglobin method was significantly different (p=0.000 ) and there was positive moderate correlation (r=0.438; p=0.000). Conclusions: Hemoglobin concentration assessment by POCT electrode-based biosensor method has shown significantly different and positive correlation with HA cyanmethemoglobin method. Keywords: hemoglobin concentration, HA cyanmethemoglobin method, POCT electrode-based biosensor method
