Working memory capacity is a crucial aspect of cognitive function that plays a significant role in supporting students' learning processes. Working memory functions as a temporary storage system that allows individuals to store and manipulate information quickly. In an educational context, optimal working memory capacity can improve students' ability to understand, process, and remember information presented during the teaching and learning process. Several factors known to influence working memory capacity include breakfast habits, nutritional status, body fat percentage, and hemoglobin (Hb) levels. These factors are closely related to students' daily nutritional intake and healthy lifestyle. This Community Service (PkM) activity, with the topic "Healthy Food and Lifestyle to Increase Working Memory Capacity," aimed to increase students' understanding and awareness of the importance of a healthy diet and an active lifestyle in supporting cognitive function, particularly working memory. This activity was held in July 2024 at MTs (Madrasah Tsanawiyah) Al Fatah, Natar District, Lampung Regency. The implementation method was interactive nutrition education, covering the importance of a nutritious breakfast, consuming a balanced diet, physical activity, and general health care. Based on the results of evaluations conducted before and after the activity, there was an increase in the average knowledge scores of female students, as well as a significant difference in their understanding of the concepts of healthy eating and a lifestyle that supports working memory function. These findings indicate that nutrition education interventions have significant potential to improve the quality of learning by enhancing students' cognitive aspects. This activity is expected to become a model that can be implemented sustainably in other school settings.

Chronic Energy Deficiency (CED) in pregnant women remains a major nutritional problem in Indonesia and contributes to various maternal and neonatal complications. CED reflects a long-term energy and macronutrient deficit, often influenced by inadequate nutritional intake and socioeconomic limitations. This study aims to analyze nutritional intake and economic status as risk factors for Chronic Energy Deficiency (CED) in pregnant women in the Patilanggio Community Health Center (Puskesmas) working area. This study used a quantitative observational design with a cross-sectional approach. The study sample consisted of 30 pregnant women selected using a total sampling technique. Data were collected through interviews using a respondent characteristics questionnaire and food recall to assess energy and protein intake, as well as Mid-Upper Arm Circumference (MUAC) measurements to determine CED status. Data analysis was conducted descriptively and cross-descriptively. The results showed that all respondents had energy and protein intakes below 90% of the Recommended Dietary Allowance (RDA) and all were categorized as CED based on the MUAC measurement. All respondents were also categorized as low economic status, reflecting a homogeneous socioeconomic condition. These findings indicate that CED in pregnant women at the study site is associated with inadequate nutritional intake and limited economic status. In conclusion, CED in pregnant women is a chronic nutritional problem influenced by nutritional and socioeconomic factors, necessitating comprehensive prevention and treatment efforts based on primary health care services.

Baby massage is a form of multisensory stimulation that involves touch, movement, as well as auditory and visual stimuli, which is known to provide various physiological and psychological benefits for babies, including increased breastfeeding frequency. This study aims to determine the relationship between infant massage and the frequency of breastfeeding in babies aged 1–6 months in the working area of the Lambai Health Center, North Kolaka Regency. The type of research used is an analytical survey with a cross-sectional approach. The sampling technique was carried out in total sampling, involving the entire population of infants aged 1–6 months who met the inclusion criteria. Data collection was carried out through observation and structured interviews with infant mothers, as well as recording breastfeeding frequencies before and after infant massage interventions. Data analysis uses relevant statistical tests to test the relationships between variables. The results showed a significant relationship between infant massage and increased breastfeeding frequency, with a p-value of 0.000 (p < 0.05), indicating that infant massage had an effect on increasing breastfeeding activity in infants. The conclusion of this study is that infant massage has a positive relationship with the frequency of breastfeeding in infants aged 1–6 months. These findings support the use of infant massage as a simple but effective intervention in supporting breastfeeding success, especially in the early stages of life. This study recommends that the practice of infant massage can be socialized more widely to health workers and parents as part of the promotion of maternal and child health. The implementation of regular baby massage has the potential to improve the nutritional status and optimal growth and development of the baby.

The nutritional status of elementary school children serves as a vital indicator of their overall growth, development, and future health outcomes. Poor nutritional status, whether in the form of undernutrition or overweight, can lead to a range of health and academic performance issues. This study aimed to assess the nutritional status of Grade 4A students at SD 064981 Cempaka Raya using anthropometric measurements and to examine the association between snacking habits and nutritional categories. A descriptive quantitative research design was employed, utilizing a total sampling approach involving all 20 students in the class. Data collection consisted of direct height and weight measurements conducted according to standardized procedures. The data were then analyzed using the WHO Anthro Plus software to classify nutritional status into undernourished, normal, overweight, and obese categories. Additionally, information on students’ snacking habits during school hours was obtained through structured questionnaires. The results indicated that 25% of students were undernourished, 50% had normal nutritional status, 20% were overweight, and 5% were obese. Bivariate analysis using the Chi-Square test demonstrated a statistically significant relationship (p < 0.001) between snacking behavior and nutritional status. Specifically, all students who reported frequent consumption of snacks at school were classified as overweight or obese, whereas those who did not engage in frequent snacking predominantly fell within the undernourished or normal categories. These findings highlight the potential role of unhealthy snacking patterns in contributing to excessive weight gain among school-age children. Based on the results, it is recommended that nutrition education programs be implemented for both students and parents, coupled with stricter regulations on the availability and sale of high-calorie snack foods within the school environment. Such measures may serve as preventive strategies to promote healthy growth, maintain optimal nutritional status, and reduce the risk of non-communicable diseases later in life.

One of the vulnerable groups facing the double burden of malnutrition is children living in Child Social Welfare Institutions (LKSA), such as the LKSA Christian Orphanage Foundation in Malang City. This LKSA holds a C-level accreditation status, indicating limited resources and inadequate facilities to support children's well-being. Preliminary research revealed that many children are unaware of their nutritional status and have not received regular health check-ups or nutritional monitoring. To address this issue, the GAES Program (Grow And Eat Smart) was developed with the goal of increasing awareness about the double burden of malnutrition and enhancing education on the importance of regular nutritional status monitoring for children. The GAES Program consists of three main activities: distribution of nutritional measurement tools (scales and height measuring instruments), education on the importance of routine nutritional monitoring, and training in anthropometric screening techniques. The program's results showed that out of the 13 participating children, 7 children (54%) were identified as undernourished, while 6 children (46%) had good nutritional status. In addition, all participants successfully understood the educational material delivered during the sessions and were able to perform anthropometric measurements independently as an initial step in screening their nutritional status. Through this initiative, it is expected that both the children and the LKSA management will become more aware of the importance of regular nutritional monitoring and take early preventive actions. Furthermore, health professionals and local health centers (Puskesmas) are encouraged to provide continuous support and interventions at the LKSA to improve the nutritional status of children and adolescents. Such efforts are essential to prevent the long-term health impacts of the double burden of malnutrition and to ensure a healthier future for children living in social welfare institutions.

Nutritional status is a measure of success in fulfilling nutritional needs in children which is shown through the achievement of body weight for age. The nutritional status of toddlers is very significant as a starting point for physical capacity in adulthood. This descriptive study uses primary data, namely data obtained from direct field observations using a questionnaire that has been designed previously to determine maternal knowledge about nutritional status in toddlers in Telaga Sari Village, Sunggal District, Deli Serdang Regency, as many as 30 people in this study. Based on research from 30 people who became respondents, the Description of Mother's Knowledge about nutritional status in toddlers in Telaga Sari Village, Sunggal District, Deli Serdang Regency, the majority of 14 people (47%) have sufficient knowledge and a minority of 6 mothers who have less knowledge (20%). Based on age, the majority were 20-35 years old (23%), and the minority were 1 person (3%) aged <20 years old. Based on education, the majority were high school (27%), and the minority were elementary school (3%). Based on occupation, the majority were employed (27%), and the minority were unemployed (7%). This study is expected to encourage village midwives to provide more information through counseling and increase mothers' knowledge about the nutritional status of toddlers to prevent malnutrition.  

Dysmenorrhea is one of the most common menstrual disorders, but it often receives little attention. The purpose of this study was to determine the relationship between nutritional status, fat intake, and iron intake with the incidence of dysmenorrhea in female Nutrition students at Surabaya State University. The method in this study was quantitative with a cross-sectional study design. The sample consisted of 92 female Nutrition students at Surabaya State University using a purposive sampling technique. The instruments used were the NRS questionnaire to measure the level of dysmenorrhea pain and the SQ-FFQ form to measure fat and iron intake. Data analysis used the Spearman Rank correlation test which showed that there was a significant relationship between excess nutritional status of 33.7% with the incidence of dysmenorrhea (p = 0.000, r = 0.832), there was a significant relationship between excess fat intake of 58.7% with the incidence of dysmenorrhea (p = 0.000, r = 0.793), and there was a significant relationship between insufficient iron intake of 94.6% with the incidence of dysmenorrhea (p = 0.000, r = 0.610).

Stunting is a chronic nutritional problem that has a long-term impact on physical growth, cognitive development, and the quality of human resources in the future. This study aims to determine the relationship between family income and nutritional status of toddlers on the incidence of stunting in the Bukit Cening Daik Health Center working area, Lingga Regency, 2024. This study used a cross-sectional design with a sample size of 62 respondents selected through purposive sampling technique. Data were collected using questionnaires and anthropometric measurements, then analyzed using the chi-square test. The results of the analysis showed that there was a significant relationship between family income and nutritional status of children under five with the incidence of stunting (p < 0.05). This finding suggests that economic conditions and nutritional status play an important role in preventing stunting. Therefore, nutrition interventions targeting low-income families need to be strengthened to reduce stunting in the area.  

Wasting affects health and threatens children potential. Direct factors such as food intake need to be maximized to improve nutritional status. This study aims to determine the differences in energy and macronutrient intake, food parenting, and exclusive breastfeeding history in wasting and non-wasting toddlers in the working area of Sidotopo Wetan Health Center Surabaya. This study is a case control study. Total respondents were 88 toddlers aged 7-60 months, consist 44 wasting toddlers taken with total sampling technique and 44 non-wasting toddlers taken with purposive sampling technique with age and gender matching. Energy intake and macronutrients were obtained by 3x24 hour food recall questionnaire, food parenting patterns obtained from filling out FPSQ (Feeding Practices and Structure Questionnaire) and FPSQ-M (Milk Version) questionnaires, exclusive breastfeeding history obtained through interviews with questionnaires, anthropometric data measured using digital scales and microtoas. Data analysis used independent t-test and Mann Whitney test. The results of this study showed there were significant differences in energy intake (p=0.000), carbohydrates (p=0.023), protein (p=0.000), fat (p=0.000), and exclusive breastfeeding history (p=0.003) and there was no significant difference in food parenting (p=0.632) between wasting and non-wasting toddlers. Parents are expected to pay attention to food intake and provide exclusive breastfeeding.

Toddlers are the age group that most often suffers from nutritional problems, both undernutrition and severe malnutrition. Nutritional needs for children need to be considered early in their lives. Malnutrition can have unavoidable bad consequences, namely the worst manifestation can cause death. It is recorded that hundreds of millions of children in the world suffer from deficiencies, meaning that this problem occurs in a very large population. Objective: To determine the factors related to the nutritional status of children at the Moanemani Health Center, Dogiyai Regency. Method:This type of research is quantitative with a Cross Sectional Study approach, the research sample was 75 children with a total sampling technique.

Results: The relationship between maternal employment and p-value (0.02) <0.05, family income valuep-value(0.39) >0.05, maternal education p-value (0.21) >0.05, and maternal knowledge p-value (0.00) <0.05 on toddler nutritional status. Conclusion: Family income and pThere is no significant relationship between maternal education and child nutritional status,workMothers and mothers' knowledge have a significant relationship with the nutritional status of children at the Moanemani Health Center, Dogiyai Regency.. Suggestion: It is expected that mothers at the Moanemani Health Center can update their knowledge about nutritional status so that the nutritional status of children is also optimal.

Background: Stunting is a chronic nutritional disorderl in toddlers that is permanent and irreparable (irreversible) if it occurs during the First 1000 Days of Life (HPK). One significant risk factor is birth spacing that is too close, which affects the mother's nutritional status and the quality of fetal nutrient intake. Objective: This study aimed to analyze the relationship between birth spacing and the incidence of stunting among toddlers on Morotai Island. Methods: An analytical study with a cross-sectional design was conducted on 30 respondents selected through accidental sampling in the Community Health Center (Puskesmas) area of Morotai. Data were collected through questionnaires, MCH (Maternal and Child Health) books, and anthropometric measurements, then analyzed using Simple Logistic Regression test. Results: The majority of respondents had a birth spacing of 3-4 years (40%), but the prevalence of stunting remained quite high at 43.3%. The statistical test results showed a p-value = 0.005 (p < 0.05), proving a significant relationship between birth spacing and the incidence of stunting. Conclusion: There is a significant relationship between pregnancy/birth spacing and the incidence of stunting among toddlers on Morotai Island.

The development targets in the Health sector in the 2020–2024 National Medium-Term Development Plan (RPJMN) place one of the main targets for maternal and child health is to reduce the incidence of children under five years old (toddlers) stunting (low height / short) by 30.8% (2018) to 19% in 2024. Optimal Health Status must be prepared since a woman before marriage. Then continued when the woman is pregnant, and while breastfeeding. Childhood is the foundation for growth and development in the next stage, if there are nutritional problems then the consequences that arise are permanent. The risk of stunting by 7x can occur in women 15-49 years who experience anemia and when they become pregnant will be at risk of giving birth to stunted babies. In women of childbearing age aged 15-49 years is the foundation for growth and development in the next stage, if during this period women experience nutritional problems then the consequences that arise can be permanent or irreversible. Its essence is a critical period when a system is plastic and sensitive to its environment, followed by a permanent loss of plasticity and functional capacity (Ummi Kalsum et al., 2021). Before education was provided, most adolescents showed a low level of understanding, namely 31 respondents (56.7%), and awareness of the importance of monitoring nutritional status during adolescence was also minimal. However, after interactive counseling with an easy-to-understand approach, there was a significant increase in knowledge, with 41 respondents (68.3%) showing an increase in understanding, reflected in a change in the knowledge category to a better level. This activity emphasizes the importance of promotive and preventive interventions in areas at high risk of nutritional problems. The implementation of direct and participatory education involving cadres and health workers has proven effective in increasing awareness and forming healthy lifestyle behaviors in adolescents. Therefore, similar education programs need to be implemented continuously to reduce anemia rates to prevent stunting and prevent stunting from adolescence.

Hemoglobin and hematocrit examinations serve as important early indicators of hematological status, reflecting the blood’s capacity to transport oxygen. A decrease in these two parameters leads to anemia, which is often undetected due to minimal early symptoms and low awareness to undergo examinations. This activity was carried out using the Plan-Do-Check-Act (PDCA) approach, by examining hemoglobin and hematocrit levels in adult participants. Capillary blood samples were analyzed using a portable device at the examination location. Education was delivered through leaflets regarding the importance of iron, vitamin B12, and folate intake to support erythrocyte formation. The examination was attended by 104 participants, the majority of whom were women. The average hemoglobin was recorded as approaching the lower limit of normal values, while hematocrit levels showed wide variations. More than half of the participants were classified as having anemia. This high proportion of anemia highlights the urgent need for targeted nutritional education. Hemoglobin and hematocrit screening proves effective as an early detection tool for hematological disorders. Education that is linked to laboratory findings should be prioritized to promote improved dietary patterns, particularly the consumption of iron-rich foods, vitamin B12, and folate, in order to prevent erythropoietic dysfunction and long-term health complications.

Nutritional problems can jeopardize the survival of a country. The nutritional condition of each individual reflects the physiological demands of that individual, because if these needs are not met, nutrition-related health problems will arise. Children's health and nutritional status are interrelated. When a child's health deteriorates due to an infectious disease, their appetite is affected and they consume less food, resulting in less nutrients entering the body. Journals in this literature review used 3 databases including Google Scholar, PubMed, and Science Direct using the words malnutrition, child, 2-5 years. The literature search was adjusted based on inclusion and exclusion criteria. The search results obtained 10 journals consisting of 4 national journals and 6 international journals. The results showed that the risk factors for malnutrition in children aged 2-5 years were inadequate nutritional intake, parental education and knowledge, infectious diseases, parenting, environmental sanitation and socioeconomic factors.

Dysmenorrhea is pain during menstruation experienced by women of childbearing age. Risk factors that can cause dysmenorrhea include age of menarche, family history, duration and menstrual cycle, stress, physical activity, nutritional status, and nutrient intake. Some nutrients that are related to the incidence of dysmenorrhea include fat, calcium, and magnesium. This study aims to determine the relationship between fat, calcium, magnesium, and physical activity intake with the severity of dysmenorrhea in students of the Faculty of Sport and Health Sciences, Surabaya State University. This study used a cross-sectional approach. The sampling technique used stratified random sampling with a total of 119 samples. Data collection used the NRS (Numeric Rating Scale) questionnaire for the incidence of dysmenorrhea, SQ-FFQ (Semi Quantitative Food Frequency) for fat, calcium, and magnesium intake, and IPAQ-SF (International Physical Activity Questionnaire-Short Form) for physical activity. The results showed that students of the Faculty of Sport and Health Sciences, Surabaya State University had low fat intake (79%), low calcium intake (58%), normal magnesium intake (47,9%), heavy physical activity (47,1%) and mild dysmenorrhea pain (40,3%). Data analysis using the Spearman Rank test showed a value of p = 0.000 (fat), p = 0.023 (calcium), p = 0.023 (magnesium), and p = 0.039 (physical activity). Based on the results of the study, it can be concluded that there is a significant relationship between fat, calcium, magnesium, and physical activity intake with the severity of dysmenorrhea (p <0.05).

Premenstrual Syndrome (PMS) is a collection of physical and emotional symptoms occurring prior to menstruation that can disrupt daily activities. Dietary patterns and nutritional status are known to influence PMS symptoms. This study aims to analyze the relationship between dietary intake (energy, carbohydrates, protein, fat, magnesium, and vitamin B6) and nutritional status (based on Body Mass Index/BMI) with the incidence of PMS among female students from both health and non-health study programs at Universitas Airlangga. This research employed an analytical observational study with a cross-sectional design. A total of 103 female students from the 4th semester of the Nutrition and Islamic Economics study programs were selected through proportional random sampling. Data were collected using questionnaires on respondent characteristics, a Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), anthropometric measurements, and the Shortened Premenstrual Assessment Form (SPAF). Data analysis was performed descriptively and inferentially using Spearman's rank correlation test. The results showed a significant relationship between energy intake (p = 0.002) and fat intake (p = 0.001) with PMS. No significant relationship was found for carbohydrate, protein, magnesium, and vitamin B6 intake (p > 0.05). Additionally, nutritional status based on BMI was significantly associated with PMS (p = 0.001), indicating that both underweight and overweight students were more likely to experience PMS. These findings highlight that imbalanced energy and fat intake, as well as abnormal nutritional status, may be contributing factors to PMS. Therefore, increasing awareness of proper nutrition and reproductive health is essential to reduce PMS symptoms among female students.

Nutritional status is the body's condition as a result of the utilization, absorption, and use of food. One of the health and social problems Indonesia is facing is the low nutritional status of its people. Nutrition deficiencies in young students will hinder mental development and brain intelligence in the future. The purpose of this study was to obtain an overview of the nutritional status of students at SD Negeri 1 Tataaran II, South Tondano District, Minahasa Regency.This research uses a descriptive survey. The population of this research are fourth and fifth grade students at Sekolah Dasar Negeri 1 Tataaran II, South Tondano District, totaling 40 students. The sampling technique used was a total population sampling, thus the sample population was 40 students. The instruments used in this study were a weighing scale, anthropometry equipment, and a list of the students’ names. Based on the research results, it was found that the nutritional status based on weight-for-age tended to be good, with 27 students (67.5%) falling into this category. The nutritional status based on height-for-age tended to be normal, with 27 students (67.5%) also in this category, and the nutritional status based on weight-for- height tended to be good, with 27 students (67.5%). In conclusion, the nutritional status of students at SD Negeri 1 Tataaran II, South Tondano District, tends to be sufficient and they generally have a good nutritional status. It is recommended that, to improve nutritional status at the household level, families should consume a diverse and balanced nutritious diet. The school, in collaboration with the health department or community health center, should routinely monitor the nutritional status of students Nutritional status is the body's condition as a result of the utilization, absorption, and use of food.

Stunting is a growth disorder in children characterized by height-for-age below the standard due to prolonged nutritional deficiency. This condition affects physical development, learning ability, and metabolic health, and it tends to be persistent. In Indonesia, the prevalence of stunting remains high. This study was conducted to identify the causes of stunting during the first 1,000 days of life. The method used was a literature review with a narrative review approach. The results show that risk factors for stunting include prenatal conditions such as low birth weight, maternal nutritional status during pregnancy, and maternal height. In addition, low maternal education, limited access to healthcare services, lack of exclusive breastfeeding, infections, and poor dietary patterns also contribute. Strategies proven effective according to the literature include early nutrition education, nutritional supplementation, and technology-based growth monitoring. The most consistently identified determinant is low birth weight (LBW).

This study aims to analyze the nutritional status and dietary needs of students aged 7–10 years at SDN 3 Sesetan. Using a quantitative descriptive survey method, the research involved total sampling of all 86 second-grade students (40 boys and 46 girls). Data were collected using a stadiometer and weighing scale. Descriptive percentage analysis was used to interpret the data. The results showed that among the participants, 3 students (4%) were classified as severely obese, 2 students (2%) as mildly obese, 32 students (37%) had ideal nutritional status, and 49 students (57%) were underweight. The average daily calorie requirement was 1,935.50 kcal. Macronutrient analysis indicated an average daily requirement of 1,195.01 kcal from carbohydrates, 298.75 kcal from protein, and 497.92 kcal from fat. These findings reveal that a significant number of students have not yet reached optimal nutritional status. The variability in nutritional needs suggests the importance of attention and collaboration from both physical education (PJOK) teachers and parents to support students' health and development.  

Eating problems in children refer to various behaviors or conditions that interfere with a child's ability to consume food properly. This can include refusal of certain foods, difficulty chewing or swallowing, and unhealthy eating habits. Eating problems in children are not a focus in everyday life, so they become an ignored problem. The presence of eating problems in children has an impact on nutritional status and health in the future. Even eating behaviors that have been patterned since childhood can continue into adolescence and even adulthood. Parental eating habits and strategies used in feeding are dominant determinants of children's eating behavior and food choices. Therefore, examining eating problems in children is important to do because this problem can affect the growth and development of children if not handled properly so that fast and appropriate treatment is needed.
