“…This finding was in agreement with the finding which is reported by a study done in Japan that protein intake may reduce iron deficiency among females. 50 This result is supported by Indonesia Baseline Health Research, that adolescents in Indonesia consume fewer vegetables, where vegetables are a source of protein.…”

Background: Iron deficiency anemia is a common problem among adolescent girls and women, with significant consequences on personal health. One of the causes of iron deficiency anemia is inadequate nutritional intake. This study explores iron-deficiency anemia and associated factors among adolescent girls and women in a rural area of Jatinangor, Indonesia. Methods: A cross-sectional study was conducted with 95 adolescent girls and 85 women between April and November 2018. Cluster random sampling was used to select the participants from seven villages in the Jatinangor district. After obtaining informed consent, we collected sociodemographic data, menstrual histories, and related data, including nutritional intake using 24-hour dietary recall. Anthropometrics were gathered to determine the body mass Index (BMI), and venous blood samples were analyzed for complete blood count and hemoglobin levels. Descriptive statistics followed by bivariate and multivariable logistic regression were used to identify anemia-associated factors. Results:The prevalence of iron deficiency anemia among the girls was 21.1% and 9.4% among women, with an average hemoglobin level in adolescents of 10.75 g/dL (± 0.79) and in adults 11.20 g/dL (± 0.61), whereas MCV was 74.49±8.22 fL in adolescents and 7.61 ±8.62 fL in adults. The majority of our samples were not stunted in growth and were also within a normal weight range. Multivariate logistic regression analysis showed that protein intake (OR=0.25; 95% CI 0.11-0.58) was a positively associated factor with anemia. Conclusion:The prevalence of iron-deficiency anemia in this study represents a mild public health problem in the study sample.Based on the hemoglobin level, anemia, can be classified as moderate in adolescents and mild in adults. Low levels of MCH indicate iron-deficiency anemia. Sufficient protein intake did not prevent anemia due to macronutrient and micronutrient intake.

“…There is a possibility that protein and fat intake may have been limited in August. Previously, we had reported an association between insufficient protein intake and a high risk of the incidence of ID 13,20) . Animal-based food groups including meats, seafood, and poultry contain more heme iron and are the most important protein sources in people's daily lives.…”

“…To maintain their ideal sports-specific body shape involved with artistic beauty, female rhythmic gymnasts often strive to lose weight, which includes restricting or skipping meals during the pre-season period before major competitions 11,12) . This could result in ID, and in fact, the incidence rate of ID in rhythmic gymnasts during the preseason (August) in rhythmic gymnasts was 51% 13) . During the pre-season (July and August), we measured both delta-aminolevulinic acid dehydratase (ALAD) activity 14) as an indicator of RBC synthesis and serum haptoglobin (Hp) concentrations 15) as an indicator of hemolysis, and reported that in Japanese female collegiate rhythmic gymnasts, in August compared to July 16) or June 17) , ALAD activity was elevated and Hp levels were decreased.…”

Female rhythmic gymnasts with dietary problems are extremely conscious of their physical shape and often are diagnosed with iron deficiency (ID). Although there are several reports on training volume and quality throughout the year, there are few reports on the association between dietary intake and prevalence of ID. The aim of this study was to examine the association between the prevalence of ID, including erythropoiesis and hemolysis, and dietary intake for 10 months. A total of 19 Japanese collegiate elite female rhythmic gymnasts participated in five surveys in four different seasons: early pre-season (April), late pre-season (July and August), in-season (October), and off-season (January). Blood samples were collected to analyze body iron status including delta-aminolevulinic acid dehydratase (ALAD) activity, erythropoietin, and haptoglobin, and dietary intake were assessed. The definition of anemia was based on hemoglobin concentrations (<12.0 g/dL), and ID was diagnosed when one of the following clinical criteria or both were met: ferritin (< 12 ng/mL) and transferrin saturation (< 16 %). A higher incidence of ID (58%) was noted in July and August. ALAD was significantly higher in July to October than in April. Erythropoietin did not show any significant changes throughout the study. Haptoglobin was significantly lower in August than in January. Intakes of energy, protein, and iron were significantly lower in August than in April. Our findings suggest that inadequate intakes such as energy, protein and iron may concern with the high incidence of ID in August when the synthesis and destruction of red blood cells is enhanced in elite rhythmic gymnasts.

“…The average student energy intake in this study was below the normal Nutrition Adequacy Rate for adolescent girl aged 15 -18 years old (2125 Kcal per day), but their protein intake was sufficient. Proteins are important compounds that have a key role in the formation of red blood cells and prevention of anemia (Kokubo et al, 2016;Wu, 2016).…”

Background: Anemia is one of nutritional problem in Indonesia, especially in society with low socioeconomic status. There are many factors that can cause anemia, including poor intake of iron rich food and also iron supplement.Objective: This study aimed to analyze consumption of iron supplement and anemia among adolescent girls.Methods: This research used cross sectional design involving 251 adolescent girls in Lamongan District, Indonesia. Data on iron supplement intake was measured using questionnaire, food intake was measured using food record and hemoglobin level measured by Quik-Check hemoglobinmeter (Acon Laboratories.inc). Data were analyzed using Pearson correlation test. Results:The average hemoglobin level of respondents was 13.43 ± 1.4 g/dl. The prevalence of anemia among adolescent girls was 13.9%. The average student energy intake was still below the normal Nutrition Adequacy Rate for adolescent girl aged 15 -18 years old (2125 Kcal per day). The test results using the Pearson Correlation test indicate that the only food intake variables that has significant relationship with hemoglobin levels was energy intake (p=0.02). Their current practice of consuming iron supplementation from government program as well as voluntary or purchased supplement was lacking. However, they did consume government's iron and folic acid supplement during their junior high school years. Conclusion:In conclusion, the current practice in taking iron supplement and food intake among adolescent girls in Lamongan district was poor. However, the prevalence of anemia was low and it was thought to be related to the success of the iron supplement program during the participants' junior high school (2-3 years ago).
