Kebiasaan konsumsi kopi teratur dan pengaruhnya terhadap resorpsi tulang: C-telopeptida dan kalsium serum pada olahragawan

Abstract

Background: Coffee is believed and predicted as one of the risk factors for osteoporosis in sedentary and athletes. Long term regular consumption of coffee can lead to hypocalcemia, increase bone resorption and risk of osteoporosis.Objectives: The aim of the study was to analyze the effect of regular coffee consumption on bone resorption, thus predicting the risk of osteoporosis in athletes. The assessment risk of osteoporosis was done by measuring the biomarkers of bone resorption, namely: C-telopeptide (CTx) and serum calcium levels.Methods: The design of this study was a cross-sectional study. The subjects were athletes with regular exercise (aerobic exercise 2 times a week, for 50-60 minutes each training session). The total of samples were 50 people (male = 37; non-coffee=21 and coffee=16 and female=13; non-coffee=7 and coffee=6). Non-coffee is a group that does not consume coffee. Coffee drinkers are a group who regularly consume coffee daily at a dose of 1-2 cups per day (150-200 ml / cup). Coffee consumption habits were obtained from questionnaire interviews. The sampling technique was a total sampling. Examination of serum CTx levels was carried out by the Electro Chemiluminescence Assay method and serum calcium levels were examined using the O-cresolphthalein complexone method. Data were analyzed using the normality test (Kolmogorov-Smirnov), homogeneity (Levene's test) and independent sample t-test, with a significant degree of 95% (p
