Identification Of Hematocrit Values In Teenagers Active Coffee Drinkers

Abstract

Coffee consumption can cause abnormal hematocrit values because coffee contains
tannins and filates which cause it can reduce the absorption of iron in the body. This type
of research is descriptive qualitative. The purpose of this study was to determine the
hematocrit value in active teenagers who drink coffee. A total of 30 samples were obtained
by Purposivve Random Sampling in teenagers actively drinking coffee in warkop or coffe
shop. The examination of hematocrit values is carried out by the hematocrit POCT
method. Based on the results of the examination of hematocrit values in coffee-drinking
adolescents, all respondents were male (100%) with the consumption of the type of coffee
that was most indemand by adolescents, namely black coffee as many as 7 respondents
(23%) normal hematocrit valuesand 17 respondents (58% ) abnormal. At the frequency of
drinking coffee 2 to 3 perday 11 respondents (37%) were normal and 10 respondents
(33%) were abnormal, at a frequency of 4 to 5 perday as many as 9 respondents (30%)
were abnormal, indicating that the higher the frequency of drinking coffee that adolescents
drink, it can affect hematocrit values, so adolescents should be able to pay attention and
reduce coffee consumption beyond a reasonable limit.
