Due to its effect on the caliber of generations to come, iron deficiency anemia in teenage females is one of Indonesia's most pressing reproductive health concerns. Adolescents' awareness to autonomously adopt preventative actions is shaped mostly by their knowledge. The purpose of this research is to determine whether there is a correlation between the prevalence of anemia among teenage females in Boyolali Regency and their degree of education. Using a cross-sectional design, this study employs quantitative correlational analytic methods. An accidental sampling approach was used to obtain a sample size of 80 respondents from the population of seventh grade female pupils. A digital POCT device was utilized to quantify the incidence of anemia variables based on hemoglobin (Hb) levels, while a structured questionnaire instrument was employed to gather data for knowledge variables. The Chi-Square test was used to assess the bivariate data analysis. According to the univariate analysis, 62.5% of the participants (50 respondents) had a decent level of knowledge, and 73.8% of the participants (59 respondents) did not suffer from anemia (Hb > 12 g/dL). With a p-value of 0.000 (p < 0.05), the results of the bivariate test were generated. Anemia is more common among female students at MTs Al Ihsan Doglo who have a higher degree of expertise, according to this study. School districts should keep an eye on students' iron pill use and improve their nutrition education programs.

Stunting is a multifactorial public health problem influenced by various risk factors that may emerge during the prenatal period. Early identification of stunting risk during pregnancy is important to support preventive interventions. This study aimed to develop a stunting risk prediction model based on maternal prenatal factors using the Random Forest algorithm. Secondary data from 172 pregnant women, consisting of 83 stunting cases and 89 non-stunting cases, were analyzed. The predictor variables included maternal age during pregnancy, height, hemoglobin level, mid-upper arm circumference (MUAC), smoking history, hypertension, asthma, and diabetes mellitus. The research stages consisted of data preprocessing, model training using Stratified 5-Fold Cross Validation, performance evaluation, external testing, and feature importance analysis. Internal evaluation results showed an accuracy of 60%, precision of 60.6%, recall of 57.3%, F1-score of 58.9%, and AUC of 0.6688. External testing yielded an accuracy of 70% and an AUC of 0.6167. Feature importance analysis identified maternal age during pregnancy as the most influential variable in the prediction process. The findings indicate that maternal prenatal factors have potential for early stunting risk identification, although the predictive performance remains moderate. This approach may serve as a foundation for developing early screening tools to support targeted interventions among high-risk pregnancies.

Iron deficiency anemia (IDA) is a condition of insufficient iron that lowers hemoglobin levels and disrupts erythrocyte formation. This condition commonly occurs in children and can weaken the immune system, thereby increasing the risk of recurrent respiratory tract infections such as bronchiolitis, pneumonia, and Acute Respiratory Tract Infections (ARTI). Children with IDA are also at risk of worsening clinical conditions. This study employed a literature review method with a descriptive-analytical approach. A total of 10 journals (2020–2026) from Google Scholar, PubMed, ResearchGate, Elsevier, and the National Center for Biotechnology Information (NCBI) were analyzed using the Population, Intervention, Comparison, Outcome, Study Design (PICOS) framework and synthesized narratively. The results of the review indicate that iron deficiency anemia is significantly associated with an increased risk of recurrent respiratory tract infections in children. Children with IDA have a 2–5 times higher risk of developing bronchiolitis and pneumonia, and up to 10 times greater susceptibility to recurrent ARTI. This condition is also associated with increased disease severity, characterized by low hemoglobin levels, mean corpuscular volume (MCV), and serum iron, as well as elevated total iron-binding capacity (TIBC). Iron supplementation has been proven effective in reducing the incidence of recurrent infections. In conclusion, iron deficiency anemia is associated with an increased risk and severity of recurrent respiratory tract infections in children. Early detection and iron supplementation are essential to reduce morbidity and prevent infection recurrence.

Low Birth Weight (LBW) refers to infants born with a birth weight of less than 2,500 grams and remains an important issue in neonatal health due to its association with increased neonatal morbidity and mortality. To analyze the determinants of LBW based on primary studies published from 2021 to 2026. A literature review was conducted using the PRISMA approach. Article searches were performed through PubMed, Google Scholar, Scopus, ScienceDirect, and ProQuest using the keywords low birth weight, determinant factors, risk factors, BBLR, and faktor risiko with Boolean operators AND/OR. The inclusion criteria were primary studies, full-text availability, publication in Indonesian or English, and publication years from 2021 to 2026. A total of 20 articles were included, consisting of 15 international articles and 5 national sources. The review showed that LBW is influenced by interrelated maternal, nutritional, obstetric, and sociodemographic factors during pregnancy. The most dominant factors included multiple pregnancy with an adjusted OR of 21.74, maternal food insecurity with an AOR of 6.85, maternal hemoglobin level <11 g/dL with an AOR of 5.21, lack of iron-folic acid supplementation with an AOR of 4.17, maternal age ≤20 years with an AOR of 3.42, pregnancy interval <1 year with an adjusted OR of 2.92, missed antenatal care visits with an AOR of 2.74, smoking during pregnancy with an OR of 2.18, and maternal hypertension with an AOR of 1.94. LBW is influenced by multiple interrelated factors; therefore, efforts to reduce its incidence should focus on evidence-based interventions, particularly through optimizing antenatal care services, improving maternal nutritional status, and early detection of pregnancy.

Anemia is a condition with hemoglobin and erythrocyte levels lower than normal, which is 12 grams/dl for adolescents. Iron deficiency anemia in adolescent girls is at higher risk because it causes a decrease in immunity, making them susceptible to health problems. One of the causes is the lack of knowledge of adolescent girls about healthy lifestyles and self-motivation regarding the importance of balanced nutrition in preventing anemia. The purpose of this study was to determine the effect of education on the level of knowledge of adolescent girls about anemia. The type of research used was quantitative research with a quasi-experimental research design with a pre-test-post-test research design. The sample consisted of 90 adolescent girls. The results showed that before being given education, the majority of respondents were in the sufficient category (45.6%), while after being given education, the majority were in the good category (84.4%). The results of this study showed that there was a significant difference in the level of knowledge of adolescent girls about anemia before and after being given education with a significance value of 0.000, which means there was a significant effect of education on the level of knowledge of adolescent girls about anemia.

Anemia is a common nutritional problem among adolescent girls and can affect health, learning ability, and the quality of future generations. Hemoglobin (Hb) levels can be influenced by dietary intake, such as folic acid and vitamin C, as well as consumption behaviors, including tea drinking habits and adherence to iron supplementation (TTD). This study aimed to examine the relationship between folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption with hemoglobin levels among adolescent girls in senior high schools in Tuban District. This study used a cross-sectional design with a sample of 325 respondents selected through probability sampling. Data on folic acid and vitamin C intake were obtained using a 24-hour dietary recall method, while tea drinking habits and adherence to TTD consumption were collected through questionnaires. Hemoglobin levels were measured directly using a hemoglobin testing device. Data analysis was performed using the Spearman correlation test. The results showed significant relationships between folic acid intake and hemoglobin levels, vitamin C intake and hemoglobin levels, adherence to iron supplementation and hemoglobin levels, and tea drinking habits and hemoglobin levels, with a negative direction of association. This study concludes that folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption influence hemoglobin levels in adolescent girls. Efforts to prevent anemia should focus on improving dietary patterns, proper use of iron supplementation, and regulating tea drinking habits.

Uterine myoma is a benign smooth muscle tumor of the uterus commonly found in women of reproductive age and may cause symptoms related to mass effect and hematologic disturbances. We report the case of a 41-year-old woman presenting with progressive vaginal pain for 3 months, accompanied by low back pain and impaired daily activities, without vaginal bleeding, vaginal discharge, fever, or urinary or defecatory symptoms. Laboratory examination revealed severe microcytic hypochromic anemia with a hemoglobin level of 4.7 g/dL, while ultrasonography demonstrated a 9.93 × 10.32 cm mass described as symmetric, well circumscribed, and hyperechoic, leading to a working diagnosis of uterine myoma with anemia. The patient was managed with general condition monitoring, intravenous fluids, analgesics, transfusion of four units of packed red cells, and laparotomy as definitive intervention. Following transfusion and surgery, the hemoglobin level increased to 9.4 g/dL and subsequently to 11.0 g/dL, accompanied by improvement in postoperative symptoms and clinical condition. This case demonstrates that a large uterine myoma may present predominantly with pelvic pain and functional impairment in the absence of vaginal bleeding. A comprehensive approach involving systematic evaluation, preoperative correction of anemia, appropriate surgical intervention, and postoperative monitoring is essential to improve safety and clinical outcomes in patients with symptomatic pelvic masses.

Iron deficiency anemia remains a major public health problem among pregnant women in Indonesia, with a national prevalence of 37.1% and higher rates in regions such as Brebes Regency. Adequate nutritional knowledge and sufficient iron intake are expected to prevent decreases in hemoglobin (Hb) levels during the third trimester. This study aimed to analyze the relationship between nutritional knowledge, iron intake adequacy, and Hb levels among third-trimester pregnant women at Puskesmas Brebes. An analytic observational study with a cross-sectional design was conducted on 62 respondents using total sampling. Data were collected through a nutritional knowledge questionnaire, a Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ) to assess iron intake based on the Recommended Dietary Allowance of 27 mg/day, and Hb measurement using a digital device. The prevalence of anemia was 32.3%, with a mean Hb level of 11.25 ± 1.74 g/dL. Most respondents had high nutritional knowledge (72.6%), but 79.0% had inadequate iron intake. Chi-Square analysis showed no significant relationship between nutritional knowledge and Hb levels (p=0.109) or between iron intake adequacy and Hb levels (p=0.426). Other factors, including iron absorption inhibitors, compliance with iron supplementation, nutritional status, and limited sample size, may have influenced the results.

Anemia remains a significant nutritional problem among adolescent girls due to increased iron requirements during growth and menstruation. Iron (Fe) tablet supplementation is commonly used for prevention, but low compliance often limits its effectiveness. Moringa oleifera leaf tea offers a potential local food–based alternative intervention. This study aimed to compare the effectiveness of Moringa oleifera leaf tea and iron tablets in increasing hemoglobin levels among anemic adolescent girls. A quasi-experimental two-group pretest–posttest design was employed in December 2025 at two junior high schools in Gorontalo City. The sample consisted of 18 adolescent girls with mild to moderate anemia, divided equally into a Moringa leaf tea group and an iron tablet group. The tea group consumed Moringa leaf tea twice daily for 14 days, while the tablet group consumed one iron tablet per week for two weeks. Hemoglobin levels were measured before and after the intervention using a digital hemoglobin analyzer. Data analysis using the Wilcoxon signed-rank test and Mann–Whitney test showed that both interventions significantly increased hemoglobin levels. However, the increase was greater in the Moringa group (ΔHb 1.4–3.2 g/dL; p = 0.008) compared to the iron tablet group (ΔHb 0.5–0.8 g/dL; p = 0.007). A significant difference between groups (p < 0.001) indicates that Moringa oleifera leaf tea is more effective as an alternative intervention.

A Normocytic normochromic anemia is one of the most common types of anemia found in geriatric patients with chronic diseases or acute bleeding. Upper gastrointestinal bleeding (UGIB) may cause continuous blood loss resulting in decreased hemoglobin levels. This case report discusses a 72-year-old woman who presented to the Emergency Department of Cut Meutia Regional General Hospital with complaints of black stools for four days prior to admission accompanied by epigastric pain, nausea, weakness, and pallor. The patient had a history of long-term use of analgesic and anti-gout medications due to chronic joint pain, which was suspected to be a risk factor for UGIB. Physical examination revealed pale conjunctiva and tachycardia, while laboratory findings showed hemoglobin of 7.1 g/dL, hematocrit of 23.3%, MCV of 82 fL, MCH of 29 pg, and uric acid level of 11.56 mg/dL, leading to the diagnosis of normocytic normochromic anemia caused by UGIB accompanied by gout arthritis. The patient received intravenous fluid therapy, proton pump inhibitors, antifibrinolytic agents, gastroprotective therapy, packed red cell transfusion, and other supportive treatments. During hospitalization, clinical improvement was observed, including cessation of gastrointestinal bleeding, reduced epigastric pain, and increased hemoglobin level to 8.6 g/dL. This case highlights the importance of early diagnosis and comprehensive management in geriatric patients with anemia caused by UGIB and comorbid gout arthritis.

Anemia in adolescents is a serious health issue that impacts students' concentration and productivity. This community service activity aims to conduct early detection of anemia through a comprehensive manual screening method at three high schools: SMA Sains Alumnika Palembang, SMA Candradimuka, and SMA Mandiri. The implementation method involved three main stages: identification of clinical signs and symptoms (5L), visual observation of the palpebral conjunctiva, and hemoglobin (Hb) level measurement using Point of Care Testing (POCT) devices. Held from April 1st to 8th, 2026, the activity involved the active participation of students and school authorities as an effort toward independent nutritional surveillance. The screening results showed a correlation between subjective symptoms, pale conjunctiva conditions, and Hb measurement results in the field. Changes in students' behavior regarding nutritional intake and the emergence of new awareness among school authorities about the importance of routine check-ups served as indicators of successful social transformation. In conclusion, integrated manual screening is highly effective as a preventive health measure for adolescents within educational environments.

Anemia during pregnancy is a major public health issue, especially in developing countries like Indonesia, contributing to maternal morbidity and adverse pregnancy outcomes. The second trimester, marked by increased iron needs due to plasma volume expansion and fetal growth, is critical for preventing anemia. Moringa leaves (Moringa oleifera), rich in micronutrients, may serve as an effective nutritional intervention to enhance hemoglobin levels in pregnant women. This study aimed to assess the impact of moringa leaf supplementation on hemoglobin levels in second-trimester pregnant women. Using a one-group pretest-posttest quasi-experimental design, the study was conducted at the Tadoy Community Health Center in Bolaang Mongondow Regency from October to November 2025, involving 25 pregnant women selected via purposive sampling. Hemoglobin levels were measured before and after the supplementation. Data analysis, including the Shapiro-Wilk test and Wilcoxon Signed Rank Test, indicated significant changes in hemoglobin levels (p = 0.000). The results showed a notable increase in hemoglobin levels post-supplementation, supporting the potential of moringa leaves as a safe, affordable, and effective intervention. This finding suggests that moringa leaves could be integrated into antenatal care and nutrition education to help prevent anemia in pregnant women.  

Background: Autoimmune Hemolytic Anemia (AIHA) is a rare immunological condition that causes the destruction of red blood cells through autoantibodies. Case Presentation: This report discusses the case of a 38-year-old woman who presented with complaints of weakness and acute dizziness at RedaBolo, with a history of recurrent anemia over the past six months. Physical examination revealed clear signs of hemolysis, including icteric sclera and splenomegaly. Laboratory findings confirmed severe anemia (Hb 5.0 g/dL) with varied peripheral blood cell morphology (spherocytes, schistocytes, and teardrop cells). The diagnosis was supported by a positive Coombs test and hyperbilirubinemia.  Management: The therapeutic strategy focused on hemodynamic stabilization through transfusion of 4 units of packed red blood cells (PRC), immunosuppression with methylprednisolone 125 mg/day, and gastric protection. Conclusion: These interventions yielded satisfactory results, with the patient achieving significant clinical improvement and a hemoglobin level of 9.5 g/dL by the fourth day of treatment.

Background: Adolescence is a transitional period from childhood to adulthood, with signs of entering adolescence including physical and psychological changes. The adolescent phase is marked by physiological maturation such as the growth of tissues and body organs. This requires adolescents to have sufficient nutritional intake. If the intake is inadequate, it can lead to disturbances in the body's metabolic processes. Nutrient deficiencies, particularly iron (Fe), can cause nutritional anemia. Low hemoglobin levels can occur due to insufficient nutrient intake from food, especially nutrients that support hemoglobin formation. Objective: The objective of this study is to determine the relationship between hemoglobin levels and BMI scores in female adolescents at SMA N 3 Boyolali. Method: The research design was correlational analytic, with a sample of 76 female students at SMA Negeri 3 Boyolali. The sampling technique used random sampling according to inclusion and exclusion criteria. The research instruments included a digital hemoglobinometer, a digital step-on scale, and a microtoa. Data were analyzed using the Spearman Rank test. Results: Bivariate analysis using the Spearman Rank statistical test showed r = 0.343 with a p-value of 0.002 < 0.05, indicating that Ha was accepted. An r of 0.343 is equivalent to 34.3%, indicating a low strength of association. Conclusion: There is a significant relationship between hemoglobin levels and BMI scores in adolescent girls.

Smoking is the activity of smoking smoke from the burning of tobacco in cigarettes, one end of the cigarette is burned and the smoke can be smoked through the mouth on the other end. If the amount or form of hemoglobin is abnormal, red blood cells cannot function properly in transporting oxygen and carbon dioxide. This can trigger various health problems, including anemia. From the results of this study, we can see that the average value or mean value of hemoglobin levels is 12.5 g/dL, the median value is 12.9 g/dL, the minimum value is 11.9 g/dL, and the maximum value is 16.2 g/dL. The results showed that most of the respondents had hemoglobin levels within normal limits. In detail, hemoglobin levels in the normal category were 23 respondents, low category was 1 respondent, and high category was 1 respondent. This shows that the majority of active smokers in Market VI of North Binjai Village still have normal hemoglobin levels, although smoking has the potential to affect oxygen transport capacity in the long term and increase the risk of health problems if it continues continuously.

Malaria remains a major public health problem in Papua, Indonesia, with a high incidence rate and significant hematological complications. One of the main impacts of malaria infection is anemia caused by a decrease in hemoglobin levels. This study aimed to analyze the relationship between hemoglobin levels and malaria parasite species among patients at Sentani Health Center, Jayapura Regency. This was an analytical study with a cross-sectional approach. A total of 50 malaria-positive patients confirmed by microscopic examination were included as samples. Data collected included gender, parasite species, nutritional status, hemoglobin level, and parasite count, analyzed using the Chi-Square test with a 95% confidence level (α=0.05). The results showed that most respondents were male (54%) and predominantly infected by Plasmodium falciparum (66%). The majority had normal nutritional status (40%), and the distribution between normal and abnormal hemoglobin levels was equal (50% each). Statistical analysis revealed a significant association between body mass index and hemoglobin level (p=0.03), but no significant relationship between parasite species and hemoglobin level (p=0.145). These findings indicate that nutritional status plays a more dominant role in determining hemoglobin levels than parasite species variation. In conclusion, anemia among malaria patients in endemic regions is influenced not only by the infecting Plasmodium species but also by individual nutritional factors. Integrated interventions focusing on nutritional improvement and malaria control are essential to reduce anemia risk in endemic areas such as Papua.

Anemia is a micronutrient deficiency problem that is common in various parts of the world. Indonesia is one of the countries with a high anemia rate. According to the 2024 Basic Health Research (Riskesdas), the anemia rate in adolescent girls reached 32%. Breakfast habits and consumption of iron supplements affect daily nutritional intake. Low hemoglobin levels occur due to infrequent iron supplement consumption and inadequate food intake, resulting in a lack of iron stores in the body. The purpose of this study was to encourage adolescent girls to continue maintaining good habits of consuming iron supplements and having a healthy breakfast. This study used a quantitative analytical observational method with a cross-sectional design. The target population was female students of SMPN 1 Nibong. The study was conducted at SMPN 1 Nibong. The sample was obtained using a cluster random sampling technique of 50 respondents. The results of the chi-square test showed a strong association between breakfast habits and the risk of anemia, with a p-value of 0.000, which is far below 0.05, so technically significant. In essence, breakfast habits and blood supplement consumption have been shown to influence the risk of anemia in adolescent girls at SMPN 1 Nibong. The school is expected to promote understanding of nutrition and the importance of breakfast and blood supplement consumption, as well as motivate students to eat breakfast and consume blood supplement tablets regularly.
