Background : Picky eater tended to reject new or unfamiliar foods. They had preferred food that lead to less food intake diversity. Futhermore, inadequate variation and amount of food intake could distrupt the growth of children.Objective : To determine the correlation between picky eatingÂ and nutritional status in preschool children.Methods : This was an observational studies with cross sectional design. Sixty-three subjects were randomly selected based on the inclusion criteria. Data collected included socio-demographic information. Picky eating was obtained through the Childrenâ€™s Eating Behavior Questionnaire. Nutritional status was measured based on weight-for-height z-score (WHZ), weight-for-age z-score (WAZ), and height-for-age z-score (HAZ).Nutrition intake was assessed by 2x24h dietary recall. Physical activity was obtained using Early Years-Physical Activity Questionnaire. Data were analyzed using Chi-square and Fisher's test.Results : The prevalence of picky eater was 52.4% in preschoolers. WHZ, WAZ, and HAZ mean were -0.3Â±1.5SD, -0.2Â±1.3SD, and HAZ -0.2Â±1.3SD, respectively. Picky eating was associated with carbohydrate and fiber intake (p<0.05). There was no correlation between picky eating and nutritional status of WHZ, WAZ and HAZ (p>0.05). Meanwhile, food intake associated with nutritional status of BB/U was energy, protein and fat intake (p<0.05).Conclusion : There was no relation between picky eatingÂ with nutritional status of WHZ, WAZ and HAZ in preschool children.

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<0.05).Results: The results showed that there was no difference between CTx in male and also female non-coffee (0.415 ng/mL vs. 0.586 ng/mL; p=0.09) and coffee drinkers (0.380 ng/mL vs. 0.512 ng/mL; p=0.35). The normal CTx level is 0.016-0.584 ng/mL. Calcium levels in male (9.70 mg/dL vs. 9.30 mg/dL; p=0.61) and female (9.28 mg/dL vs. 9.23 mg/dL; p=0.72) non-coffee and coffee drinkers were not significantly different. The normal Calcium levels is 9.2-11.0 mg/dL.Conclusion: Regular consumption of coffee does not cause increased CTx and decreased calcium in athletes. Coffee does not cause increased bone resorption, triggers hypocalcemia, therefore regular coffee consumption in physiological doses (1-2 cups/day) is not at risk for early osteoporosis in young athletes.
