Adolescence is a period of change or transition from childhood to adulthood, encompassing biological, psychological, and social changes. Adolescent girls experience menstruation every month, which puts them at risk of anemia, compounded by poor dietary habits and the failure to consume iron tablets. Rapid adolescent growth is linked to nutritional fulfillment or adolescent consumption of nutrients, one of which is iron consumption. Insufficient iron consumption can lead to anemia in adolescents. Strategies to address anemia in adolescent girls include improving dietary intake and providing iron tablet supplementation. Changing dietary patterns is an important long-term strategy, but cannot be expected to be successful quickly. Anemia is a global health problem, especially in developing countries, where an estimated 30% of the world's population suffers from anemia. Adolescent girls are ten times more likely to suffer from anemia than boys. Efforts to prevent anemia in adolescents through iron tablet supplementation are a strategic, specific intervention to prepare healthy mothers-to-be. The aim was to determine the effect of iron (Fe) tablet administration on increasing Hb levels in adolescent girls with mild anemia. This study was quantitative, with an experimental design. The population in this study were 55 young women at the Ibu Health Center in West Halmahera Regency. A purposive sample of 30 samples was taken. Data collection in this study was carried out by examining Hb levels before and after administering iron tablets 4 times in a row for 4 weeks. The results of the study were that there was no significant difference between Hb levels before and after administering iron tablets in young women at the Ibu Health Center in West Halmahera Regency. The average Hb level before administering iron tablets was 11.5 g/dL, and after administering iron tablets was 12 g/dL. The results of the paired t-test showed a difference before and after administering iron tablets (p value = 0.001), so the test has an effect on administering iron tablets (Fe) on increasing Hb levels in young women with mild anemia in the Ibu Health Center in West Halmahera Regency.

Anemia in toddlers is a serious nutritional problem that impacts physical growth, cognitive development, and the child's immune system. This study aims to provide an overview of the level of knowledge, attitudes, and practices of parents in preventing anemia in toddlers. This quantitative study involved 50 respondents using a structured questionnaire instrument covering the domains of knowledge, attitudes, practices, and sources of health information. The results showed that respondents' knowledge was in the adequate category; although all respondents (100%) understood the negative impact of anemia on growth and intelligence, only 80% understood the technical definition and clinical symptoms accurately. In the attitude domain, respondents showed a very positive response (100%) to the importance of balanced nutrition and early prevention. Regarding the practical aspect, although regular visits to integrated health posts (Posyandu) reached 100%, the consistency of daily animal side dish intake remained at 80%. An interesting finding showed a shift in information sources, with social media (80%) dominating over direct exposure to information from health workers (40%). This study concluded that there is a gap between positive attitudes and consistent daily practices, and the need to optimize health education through digital media by medical personnel to reduce the incidence of anemia in toddlers.

Background: The postpartum period is a critical phase requiring optimal nutritional intake for maternal recovery and ensuring the quality of breast milk. In densely populated urban areas such as Semampir District, dietary quality is often influenced by the level of nutrition knowledge and household economic conditions. Objective: This study aims to analyze the relationship between nutrition knowledge and household food security with dietary quality among postpartum mothers in Semampir District, Surabaya. Methods: This was an observational analytical study with a cross-sectional design. A total of 340 postpartum mothers were selected using simple random sampling. Nutrition knowledge was measured through a structured questionnaire, food security was assessed using the Household Food Insecurity Access Scale (HFIAS), and dietary quality was measured using the 3-level Balanced Diet Index derived from 24-hour food recall data. Data were analyzed descriptively and through the Chi-Square correlation test. Results: The findings indicated that the majority of respondents possessed a good level of nutrition knowledge (average correct answers >75%), with the highest score in anemia prevention (81.2%) and the lowest in the functional role of Vitamin A (75.9%). Dietary quality assessment revealed that most respondents were in the [Select: Moderate/Poor] category based on IGS scores. Bivariate analysis showed a significant relationship (p < 0.05) between both nutrition knowledge and household food security with the dietary quality of postpartum mothers. Conclusion: Good nutrition knowledge and stable food security contribute positively to the dietary quality of postpartum mothers. Targeted nutritional education regarding micronutrients and strengthening food access at the household level are essential to optimize maternal health during the postpartum period in urban settings.

The health of pregnant and breastfeeding women is a crucial determinant of the quality of future generations, particularly during the first 1,000 days of life. However, nutritional problems, such as deficiencies in iron, protein, and essential vitamins, remain prevalent in many regions, especially in rural areas. These conditions may increase the risk of anemia, impaired fetal growth, and reduced maternal and child health outcomes. This community service program aimed to improve the nutritional status as well as the knowledge and awareness of pregnant and breastfeeding women regarding the importance of balanced nutrition in Sukorejo Village, Bojonegoro Regency. The program was implemented through the provision of free balanced nutritious meals tailored to the nutritional needs of pregnant and breastfeeding women, accompanied by health education activities, including counseling sessions and interactive discussions on healthy dietary patterns, food hygiene, and anemia prevention. Program evaluation was conducted through participatory observation and participant feedback. The results indicated an improvement in participants’ understanding of balanced nutrition and positive behavioral changes in daily food selection and consumption. This community service initiative is expected to serve as a sustainable model for improving maternal and child health and preventing nutritional problems at the village level.

Anemia is one of the most common nutritional problems in the world and is mainly caused by iron deficiency. In Indonesia, the prevalence of anemia among adolescents remains high, especially in adolescent girls who have greater iron requirements due to growth and menstruation. Low levels of knowledge, unbalanced dietary patterns, and poor adherence to iron supplementation are the main factors contributing to anemia in this group. Therefore, efforts to increase knowledge through health education activities are needed. This Community Service activity aimed to increase the knowledge of adolescent girls about anemia prevention through improving iron intake and adopting a healthy lifestyle. The activity was carried out in Bongohulawa, Limboto District, Gorontalo Regency, on November 3, 2025, involving 40 adolescent girls. The methods used included health education, interactive discussions, demonstrations, and distribution of educational media. Evaluation was conducted using a pre-test and post-test. The pre-test results showed that only 25% of participants had good knowledge, while 45% had moderate knowledge and 30% had poor knowledge. After the educational intervention, the percentage of participants with good knowledge increased to 75%, moderate knowledge decreased to 20%, and poor knowledge decreased to 5%. It can be concluded that this educational activity was effective in increasing adolescent girls’ knowledge of anemia prevention and the importance of iron intake and a healthy lifestyle as early preventive measures.

Recurrent aphthous stomatitis (RAS) is a common inflammatory condition of the oral mucosa characterized by round or oval ulcers with well-defined reddish borders and a shallow base covered by a grayish or yellowish fibrinous pseudomembrane. RAS is generally classified into three clinical types—minor, major, and herpetiform based on the size, number, and duration of the lesions. Several factors contribute to its occurrence, including bacterial infections such as Streptococcus sanguis, immune system dysfunctions, and nutritional deficiencies involving iron, vitamin B12, and folic acid. Other potential triggers include local trauma, hormonal or endocrine imbalances, psychological stress, and allergic reactions. Among these, anemia due to deficiencies in iron, folate, or vitamin B12 is considered an important etiopathogenic factor, although its exact role has not been fully clarified. The management of RAS primarily focuses on symptom relief, promoting faster ulcer healing, and preventing recurrence through both topical and systemic approaches. Effective treatment often includes improving nutritional intake, maintaining oral hygiene, and addressing underlying systemic or psychological conditions. Understanding the multifactorial causes of RAS is crucial in developing comprehensive strategies for prevention and long-term management of this recurrent oral lesion.

Anemia is a common health problem among adolescents, often caused by iron deficiency. This educational activity aimed to improve students' knowledge about the role of iron in preventing anemia.

It can be concluded that this educational activity was quite beneficial in increasing students’ knowledge about the importance of iron in anemia prevention.

Early marriage remains a significant issue contributing to the high prevalence of stunting in Indonesia, particularly in rural areas. The lack of awareness among adolescents and parents regarding the negative impacts of early marriage and the importance of proper nutrition is a major contributing factor. The PENA EMAS (Early Marriage Prevention for Stunting Elimination Towards Healthy Children) program was implemented in Tanjung Buaya Village as part of the KKN-T Posko 22 UNIMMAN initiative to raise public awareness about the dangers of early marriage and its link to stunting risk. This program utilized three main stages: preparation, implementation, and evaluation. Activities included educational sessions, adolescent health screenings, local vegetable planting initiatives, and interactive media such as podcasts and educational competitions. The evaluation results showed an increase in community awareness of family planning and nutrition fulfillment, with five adolescents identified as having anemia based on hemoglobin (Hb) level tests. The conclusion of this program is that community-based educational interventions with participatory approaches can enhance awareness among adolescents and parents in preventing early marriage and reducing stunting risk. Recommended follow-up actions include regular health check-ups, adolescent mentoring, and the empowerment of Youth Ambassadors for Stunting Prevention to ensure the program’s sustainability.

Chronic Energy Deficiency (CED) in pregnant women can cause children born with cognitive decline, risk of stunting, and risk of chronic diseases in adults. The problem of pregnant women in CED is caused by low nutritional intake. Pregnant women with anemia are at 4.13 times greater risk of giving birth to children with short birth length compared to mothers who are not anemic. CED in pregnant women can cause risks and complications including anemia, bleeding, maternal weight does not increase normally and contracting infectious diseases. CED in pregnant women can affect the growth process of the fetus and can cause miscarriage, abortion, stillbirth, neonatal death, congenital defects, anemia in infants, intrapartum asphyxia, and low birth weight (LBW). Based on a survey conducted at the Cendana Putih Health Center, 45 pregnant women experienced CED (12.4%) in 2023. The problems that occur can be overcome by holding a collaborative program that can improve the health of pregnant women. This program can be used to address problems appropriately, namely by empowering pregnant women and cadres through GerCep CED. The design used in this program is community service activities carried out in the form of education in the form of providing pocket books and conducting direct counseling during the schedule of pregnant women's classes and assistance in making PMT from local food ingredients. The conclusion of this activity is that participants who initially had a low level of knowledge of KEK in pregnant women became more knowledgeable about KEK in pregnant women.

Pregnant will experience an increase in blood volume and this causes iron requirements to increase. Iron needs can be met by food consumed daily with the addition of iron supplements and if iron needs are not met it can cause anemia. Anemia in pregnant can increase the risk of premature birth, maternal and child death, and infectious diseases. Anemia can affect the growth and development of the fetus or baby during pregnancy or after. The government's efforts to prevent anemia include improving the quality of health services, financing health insurance, providing 90 blood supplement tablets during pregnancy, and health education about nutrition and preventing anemia. Increasing knowledge is urgently needed to strengthen awareness in increasing knowledge and behavior in preventing anemia in pregnant. One of the efforts made is health education activities regarding the prevention and early detection of anemia in pregnant. The result of this community service activity is that there is an increase in knowledge about anemia in pregnant before and after being given health education
