This study was conducted in June-August 2019 at Universitas Diponegoro, Central Java. this study used cross sectional design with a total of 120 female students aged 17-21 years and selected using purposive sampling method. Study variables included SAD, SAD/Height, ADI and insulin resistance level. SAD was measured by abdominal caliper, SAD/Height was ratio of SAD divided by height. ADI was ratio of SAD divided by thigh circumference. The value of insulin resistance was obtained from the calculation of homeostasis model assessment insulin resistance (HOMA-IR). Data normality was analyzed by Kolmogorov-smirnov test, all data were not normal distribution so the bivariate test analyzed by Rank spearman test. Results: As many as 42.5% subjects had SAD which included at risk and 83.3% subjects had suffering insulin resistance. There was significant relationship between SAD, SAD/Height, ADI with insulin resistance (SAD (p=0.001), SAD/Height (p<0.001) and ADI (p=0.003). In addition, SAD, SAD/Height, ADI were significant relationship with fasting blood glucose (SAD (p=0.048), SAD/Height (p=0.022) and ADI (p=0.003). Conclusion: There were significant relationship between SAD, SAD/Height, ADI with insulin resistance and fasting blood glucose in obese adolescent female.
An adolescent female athlete has a high risk of suffering iron deficiency. Low-quality diets reflect a lack of variety, adequacy, balance, and moderation, but these have not been associated with iron deficiency. This study aimed to analyze the relationship of diet quality with iron deficiency. Methods, the research was conducted at the Student Center for Education and Sports Training Central Java, the Salatiga athletic club, the Semarang State University athletic, and the swimming club. The subjects were 82 female athletes aged 13-21 years who were selected by purposive sampling. The variables of this study were diet quality and iron deficiency. The diet quality measured by assessing food consumption used the Semi-Quantitative Food Frequency Questionnaire and then the diet quality score calculated by Diet Quality Index-International. Iron deficiency measured based on serum ferritin level. The bivariate was analyzed by the Rank Spearman test. Results, as many as 17,1% of subjects suffering iron deficiency and 95,1% of subjects had low diet quality. Diet quality and its component; Variety, adequacy, moderation, and overall balance were associated with serum ferritin (p<0,05). Energy, protein, iron, fiber adequacy also related to serum ferritin, but vitamin C adequacy was not related to this. In conclusion, low-quality diets are associated with iron deficiency in female athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
