Morphological Identification of Erythrocytes in Adolescent Males Who Consume Coffee

Abstract

Abstract. Coffee contains a lot of substances which, if consumed in excess, will have a bad effect on
health, caffeine is no exception. Caffeine can affect the absorption of iron in the body. The purpose of
this study was to determine the characteristics of the respondents and the morphology of the
erythrocytes. This type of research is descriptive qualitative. The sampling technique was carried out
by Simple Ran-dom Sampling of 35 respondents who met the inclusion criteria. The primary data
collection technique was carried out by filling out questionnaires by respondents. Then, blood
sampling was carried out using micro-sampling techniques on capil-lary blood, and peripheral blood
smears were made. Finally, the peripheral blood smear was stained using wright paint. The
identification of erythrocyte morphol-ogy in coffee-consuming male adolescents residing in the
working area of the Sumobito Health Center in the age range of 18-21 years with the highest frequen-
cy at the age of 21 (37.14%). All respondents consumed 2 to 3 cups of coffee a day. The frequency of
drinking coffee for more than five years was 71.45%. The type of coffee consumed was black coffee
77.15%. The results showed that 60% of the respondents had erythrocyte morphology abnormalities
or abnormal color, shape, and size indicators. It is expected that teenagers who consume coffee will
reduce their consumption because coffee contains caffeine. Caffeine in the body may affect the
absorption of iron in the body. Lacking iron for the processing of forming red blood cells can lead to
iron deficiency anemia.
