The Nutrition Awareness Family Education Movement (KADARZI) Towards An Independent Family For The People Of Jombok Village, Kec. Ngoro Jombang

The Nutrition Awareness Family (KADARZI) is a government program implemented to address nutritional problems. Families are expected to be able to independently realize good nutritional conditions to improve the health of mothers and children and their entire families. This community service aims to provide education and assistance to create healthy, independent and nutrition-aware families. The problems faced by partners in Jombok Village, Ngoro District, include ( 1). Lack of understanding of Family Independence in this case is the development of adolescent character so that it has an impact on adolescent behavior and nutrition, (2). Young Marriage and divorce are relatively high in 2020 to 2021; 3) Lack of Knowledge about Good Parenting for Toddlers, Teenagers and Pregnant Women. The method used in this service program is 1). with an asset based community driven development approach through education and mentoring that leads to the context of understanding and internalizing assets, potential, strength and utilization independently and optimally; 2). Discussions in the form of questions and answers but more precisely sharing experiences on how to instill and develop character in adolescents as well as family nutritional development. The results of this dedication are 1). Increased understanding of the role of the family (father/mother) as the embodiment of a healthy, independent family and a nutrition-aware family, (2) Increased understanding of the mindset and parenting pattern as well as the problems faced by adolescents as the embodiment of a healthy, independent and stunting-free family.

Web-based nutrition: a useful resource for cancer patients?

An accessible and affordable way to deliver behavior change programs to a large proportion of the growing community of cancer patients and survivors is through web-based methods of nutritional counselling. The aim of this systematic review was to evaluate the effectiveness of web-based nutritional therapies targeting physical activity, diet, and/or weight control for cancer patients or survivors, primarily disseminated via modern technologies (mobile phone applications) or online. The authors conducted a structured search of the PubMed database. Studies that have focused on physical activity (PA) and dietary change and/or weight control in adolescent and adult cancer patients and survivors have reported outcomes conducted via a broad modality. Nine articles focused on web-based nutrition for patients with cancer and cancer survivors. They were conducted in the United States, Australia, Korea, China, and in the United Kingdom, and were published between 2018 and 2022 in a variety of scientific journals. The number of participants ranged from 20 to 159. Web-based nutrition counselling helps cancer patients and survivors improve their dietary intake, impacts their weight and quality of life, and promotes a healthy lifestyle. Future research should evaluate (1) the differences in cost and coverage between face-to-face and web-based nutrition, (2) long-term outcomes, (3) cost-effectiveness, and last but not least, (4) the effectiveness of web-based nutrition in adolescents and children who suffer from cancer or who survived cancer, as nutritional status and body composition have a marked impact on clinical outcomes during and after treatment. The strength of this review lies in the large number of randomized controlled trials, which offer a guarantee of effectiveness and objectivity compared to cross-sectional studies.

What Do United States Adolescents Eat? Food Group Consumption Patterns and Dietary Diversity from a Decade of Nationally Representative Data

BackgroundAlthough the importance of adolescent nutrition has gained attention in the global nutrition community, there is a gap in research focused on adolescent dietary diversity and food group consumption. ObjectivesThis study aimed to characterize population-level food group consumption patterns and quantify the extent of dietary diversity among United States adolescents using a large nationally representative sample of adolescents aged 10–19 y. MethodsWe used 24-h dietary recall data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018 to construct the 10 food groups comprising the minimum dietary diversity for women (MDD-W) indicator and estimated the prevalence of intake of each food group. A composite metric adolescent dietary diversity score (ADDS) was derived for each adolescent where 1 point was awarded per food group. Both population scores and the distribution of individual scores were estimated. Differences in proportions of food groups consumed across sociodemographic categories were tested using the Rao–Scott χ2 test, and pairwise comparisons were expressed as population prevalence differences and prevalence ratios. ResultsFood group consumption patterns were very similar across 2 d of dietary recall but varied significantly by sex, race/ethnicity, and income status. The food groups with the highest prevalence of consumption were grains, white roots, and tubers (∼99%), milk products (∼92%), and meat, poultry, and fish (∼85%), whereas <15% of adolescents consumed key micronutrient-dense foods, such as vitamin A–rich fruits and vegetables and dark green vegetables. The mean ADDS was 4.69, with modest variation across strata. ConclusionsOn average, United States youth consumed fewer than 5 food groups on a given day. The lack of dietary variety and relatively low prevalence of consumption of several micronutrient-rich plant-based foods could pose a risk for adolescents’ ability to achieve micronutrient adequacy in the United States.

The Effect of Nutrition Education on Knowledge, Attitudes and Consumption Patterns of Young Women in Prevention of Chronic Energy Deficiency in Bengkulu City

Adolescents is one of age groups vulnerable to nutritional status. Adolescence requires higher nutrition in order to optimize physical, cognitive and psychosocial growth. Lifestyle and diet of adolescents will affect the fulfillment of nutritional needs. Nutrition education can be carried out properly and can be received directly depending on how the message is conveyed, how the message is received and where the message is delivered. Barriers to prevention of chronic energy deficiency in adolescents can be sourced from environmental influences. Several studies The existence of significant changes in behavior in eating patterns through interventions from nutrition education can prevent Chronic Energy Deficiency (CED) in adolescents. This research aims to evaluate the impact of nutrition education on knowledge, attitudes and consumption patterns in prevention of CED in Young Girls SMPN 19 Padang Serai and SMKS Kampung Bahari, Bengkulu City. This study used quasi experiment with a two-group pre-test and post-test design. The intervention was carried out in the form of nutrition counseling using booklets or modules with a frequency of 3 meetings in 3 weeks. Nutrition education is promoting nutrition messages through education with a learning process using booklets individually and in groups using the lecture method. This study resulted an increased in knowledge, attitudes and consumption patterns after being given nutrition education in prevention of chronic energy deficiency of young women in Bengkulu City (p=0.000). There is an increase and influence between knowledge, attitudes and consumption patterns after being given adolescent nutrition education.

Alterations in Dietary Behavior, Appetite Regulation, and Health-Related Quality of Life in Youth with Obesity in Germany during the COVID-19 Pandemic.

This study aimed to evaluate the impact of the COVID-19 pandemic on the nutritional patterns, eating behavior, dietary content, and health-related quality of life (HrQoL) of adolescents with preexisting obesity. Anthropometric and metabolic parameters were measured, and validated questionnaires on eating habits, nutritional content, and HrQoL were administered to 264 adolescents with obesity during the COVID-19 pandemic (June 2020-June 2022) and 265 adolescents with obesity before the pandemic (from June 2017 to June 2019). Both study cohorts were comparable in age and sex distribution. Significant differences were found between the COVID-19 and pre-COVID-19 cohorts in HOMA-index (3.8 (interquartile range [IQR])): 3.3; 4.1) vs. 3.2 (IQR: 2.8; 3.5, p < 0.001), total cholesterol (208.8 mg/dL (IQR: 189.9; 214.5) vs. 198.5 mg/dL (IQR: 189.5; 207.4), p < 0.001), and GPT (93.4 (IQR 88.7; 96.5) vs. 72.8 U/L (IQR 68.9; 75.7), p < 0.001). The COVID-19 cohort reported significantly higher consumption of obesity-promoting food components, such as soft drinks, meat, sausages, fast food and delivery food, chocolate, and sweets. There was also a significant decrease in cognitive hunger control (p = 0.002) and an increase in distractibility potential (p = 0.001) while eating. HrQoL was significantly lower in the COVID-19 cohort (p = 0.001). This study reveals the adverse associations of exposure to the public health measures during the COVID-19 pandemic with nutrition, dietary content, and HrQoL in adolescents with preexisting obesity. These findings underscore the importance of tailored preventive and treatment strategies for addressing the specific challenges of disruptive events such as pandemics, especially in population-based context.

The Nutritional Needs of Mothers and Babies: A Review

The aim is to assess the importance of measuring healthy habits by pregnant women, that enhance different factors of mother and fetus health. We evaluate the change and variations in dietary recommendations. A female went through a lot of physical and mental changes in different stages of pregnancy and there are some common symptoms such as vomiting, fatigue, nausea, frequent urination, dizziness, etc. Certain hormonal changes are there to balance the body’s fatigue, tiredness, and hormones, few dietary recommendations are mentioned and it has been concluded that diet plays an important role during pregnancy, and meeting all the nutrition needs is an essential factor in planning the diet. Many diseases/deficiencies are there such as goiter, iodine deficiency, folate deficiency, gestational diabetes mellitus, gestational weight gain, Neural tube defects, and much more. A detailed view is mentioned below in the following paper: On average, pregnancy lasts 40 to 42 weeks (Nine months). On average, weight gain for a pregnant woman is 12 to 14 kg, thus weight gain can lower the risk of complications during labor and also lower the risk of LBW (low birth weight). Low GWG increases the risk of having an LBW infant. The average weight of the baby should be 2.5–3 kg. A baby having this much body weight should be considered a healthy infant. We provide up-to-date advice for achieving optimal nutrition before conception, throughout breastfeeding, in the first two years of life, and for preschoolers, with an eye on long-term health benefits. These guidelines are intended to aid in the primary prevention of obesity and the non-communicable diseases it is linked to among economically privileged groups, such as European women and children. Medical professionals should be incentivized and educated to promote and advise patients on preconception nutrition, which includes enhancing adolescent nutrition and health. Women who are physically active, eat healthily, don’t smoke, don’t drink excessively, and have a good body mass index (BMI) have a higher chance of having a safe pregnancy. Women of childbearing age should have their consumption and status of specific micronutrients closely monitored, especially folate. Women at risk for insufficient dietary intake of certain micronutrients may benefit from taking dietary supplements containing iron, vitamin D, vitamin B12, iodine, and maybe others. Smoke and alcohol should be strictly eliminated from the diet. Yes, diet plays an important role during pregnancy but staying physically active is equally important for the mother and the baby to promote general health and well-being. Exercise and stretching can reduce the risk of excessive maternal weight gain or gestational weight gain(Obesity). A long walk can greatly help a pregnant woman after lunch or in the morning.

Understanding Cultural Perceptions of Health in Middle School Females for Obesity Prevention: A Case Study

The purpose of this study was to understand acculturation and race/ethnicity influences in the home and school environment that affect physical activity and nutrition in female adolescents attending middle school. A convenience sample of eight female adolescents (&lt;em&gt;n&lt;/em&gt; = 2 Asian American, &lt;em&gt;n&lt;/em&gt; = 2 Black, &lt;em&gt;n&lt;/em&gt; =2 Latinx/Hispanic, and &lt;em&gt;n&lt;/em&gt; = 2 White) was interviewed individually via Zoom. Responses regarding acculturation, physical activity, and nutrition in the home and school environment were analyzed using qualitative case study analysis. Three themes were identified: 1) experiences related to home, health, and culture, 2) the intersection between school meals and personal culture, and 3) the intersection between school physical activity and personal culture. Study findings can inform policies on school nutrition and physical activity and lead to opportunities for students and families to collaborate with schools to improve adolescent health.

Nutrition physiology derangement as a result of changes in eating behavior of modern urban adolescents

Violation of the nutrition physiology, addiction to fast food, and lack of a regimen and food culture have been identified in modern urban teenagers. The consequence of eating disorders in the form of overeating is obesity, which is an extremely urgent healthcare problem today in all economically developed countries of the world. As a result of the changed stereotype of nutrition and eating behavior in children and adolescents, such persistent health disorders as overweight and obesity have been identified. Treatment of such children and adolescents should begin with the correction of eating behavior and a return to physiological nutrition. The authors analyzed the eating behavior of adolescents with obesity and those with normal weight, using survey methods. As a result of the study, we have identified violations in the quali tative composition of nutrition in adolescents. These violations were observed both in the main and the control groups and had a unidirectional character. However, in adolescents with obesity, an insufficient intake of high-quality proteins from natural products, a wide use of foods containing hidden fats, and the consumption of a large amount of carbohydrates were noted significantly more of ten.

Kaitan Kebiasaan Makan dan Aktivitas Fisik pada Remaja dengan Kejadian Gizi Lebih di Smpn 1 Kota Bengkulu

Background: Nutrition is more commonly known as obesity is a condition where the calories consumed are more than the calories used causing excessive accumulation of fat in the body which can result in health problems. Objective: This study plans to find out information about excess nutrition in adolescents, especially junior high school students, regarding the relationship between eating habits and physical activity with the incidence of overweight Methods: The population in this study were class 7 and 8 with a total sample of 62 people with a cross sectional study design. Data analysis used bivariate analysis using the Chi Square tes.t. Results: there are more unhealthy eating habits than good habits, while for very light physical activity there are more than light activities. Conclusion: There is a relationship between eating habits and physical activity with the incidence of overweight in junior high school adolescents. Poor eating habits and very little physical activity can potentially lead to over nutrition.

Pemantauan Status Gizi dan Deteksi Dini Kekurangan Energi Kronis (KEK) serta Pemberian Edukasi Kesehatan secara Holistik dalam Upaya Peningkatan Kesehatan Reproduksi pada Remaja Putri di SMP YPI Ciparay Kabupaten Bandung

From 10–19, adolescence is a transition from childhood to adulthood. There will be changes in the shape and function of the body in a reasonably short time. Sufficient and adequate nutrition for adolescents is one factor affecting their reproductive health. This community service aimed to monitor nutritional status and detect early signs of Chronic Energy Deficiency (CED). Monitoring of nutritional status is carried out for adolescents, especially young women. Physical health and healthy reproductive organs are essential in preparation for becoming healthy expectant mothers who can later give birth to a healthy generation. Holistic health education was needed in adolescents' growth to become better human beings in terms of their health. This activity was carried out in May 2023 at Junior High School, YPI Ciparay, and Bandung Regency. The target audience was young girls in 7th grade; there were 82 people. At the time, the students filled out questionnaires about their characteristics. Then the team measured the anthropometrics to determine the nutritional status and the incidence of CED by weighing, measuring height, and measuring upper arm circumference. The measurements showed that the nutritional status based on body mass index for most female students was standard, about 60.97%, and 41.46% of female students were CED. Counselling and health information were also provided holistically to increase the girls' understanding of their health status.

Pendampingan Remaja Putri dalam Deteksi Dini Pencegahan Anemia di Pondok Pesantren Nurul Falah, Kabupaten Lebak

Anemia can impact of body to susceptible disease, decreasing learning activities and reducing concentration. Therefore, early detection is needed to prevent anemia in young women. This activity aims to identify knowledge about anemia and the incidence of anemia in young women. The targets for this activity were young women at the Nurul Falah Islamic Boarding School Lebak Regency. This activity was carried out from August to October 2022. The method used in the intervention was the provision of adolescent nutrition education, Hemoglobin examination and administration of Fe tablets. During monitoring, a haemoglobin check is performed again, and the final evaluation by measuring Hb levels. The activity results showed that the health education provided successfully increased students' knowledge about anemia and its prevention. This program can be seen from the average value (mean), which was initially 46.8 to 73.6 after being given counselling. The incidence of anemia is 46.6%. However, after intervention in the form of counselling in detecting and preventing anemia and administration of Fe tablets consumed every week for two months, it became 10%. So it can be concluded that there was an increase in the score of the knowledge of young students about anemia in detecting and preventing it, and there was a decrease in the incidence of anemia in female students after accompanying the consumption of Fe tablets. It is suggested that female students will be more concerned about early detection and prevention of anemia.

The role of gender inequities in women's access to reproductive health services: a population-level study of Simiyu Region Tanzania

BackgroundAmref Health Africa, with support from Global Affairs Canada, examines if women's access to reproductive health services in Tanzania is affected by Gender social norms, decision-making power, roles and responsibility, and access to resources in relation to the utilization of reproductive Health Services in Tanzania. A Gender Need Assessment (GNA) was conducted in five districts in ' 'Tanzania Simiyu Region to improve the infrastructure, supply, quality, and demand for integrated Reproductive, Maternal, Newborn, and Child and Adolescent Health (RMNCAH), Nutrition, and Water, Sanitation, and Hygiene (WASH) services. The analysis identifies gender as a fundamental maternal and child health driver through existing gender inequality at the household and community levels that dictates women's status.MethodsThe qualitative assessment involved data collected from gender- and age-desegregated focus group discussions (FGDs) and in-depth interviews (IDIs) of key informants in three districts; Bariadi, Busega, and Meatu, in Simiyu region, Tanzania. Participants comprised 8-10 married women and men, unmarried women and men, and adolescent boys and girls. A total of 129 participants were involved in the FGDs.ResultsThis paper reports the critical drivers influencing gender inequality in Simiyu by detailing how Gender inequality affected women's access to reproductive health care in relation to; gender social norms, decision-making power, access to resources at the household and community level, roles and responsibilities, including men's and 'boys' roles are more valued than the roles and responsibilities of women and girls resulted to limited free time to do things for themselves, such as visiting the health facilities for RMNCAH.ConclusionsThis paper explored gender-based enablers and/or barriers influencing women and girls' realization of their sexual and reproductive health and rights. It was found that social norms, decision-making powers, and lack of access to and control over resources presented as key barriers. In contrast, continuous community sensitization and increased scope of women's participation in decision-making served as enabling environment to overcome gender inequities that influence woman's use of RMNCAH services in Tanzania. Such insights will shape interventions geared towards valuing differences in a manner that overcome gender inequities that influence woman's use of RMNCAH services in Tanzania.

Development of a genetic risk score to predict the risk of hypertension in European adolescents from the HELENA study.

From genome wide association study (GWAS) a large number of single nucleotide polymorphisms (SNPs) have previously been associated with blood pressure (BP) levels. A combination of SNPs, forming a genetic risk score (GRS) could be considered as a useful genetic tool to identify individuals at risk of developing hypertension from early stages in life. Therefore, the aim of our study was to build a GRS being able to predict the genetic predisposition to hypertension (HTN) in European adolescents. Data were extracted from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) cross-sectional study. A total of 869 adolescents (53% female), aged 12.5-17.5, with complete genetic and BP information were included. The sample was divided into altered (≥130 mmHg for systolic and/or ≥80 mmHg for diastolic) or normal BP. Based on the literature, a total of 1.534 SNPs from 57 candidate genes related with BP were selected from the HELENA GWAS database. From 1,534 SNPs available, An initial screening of SNPs univariately associated with HTN (p < 0.10) was established, to finally obtain a number of 16 SNPs significantly associated with HTN (p < 0.05) in the multivariate model. The unweighted GRS (uGRS) and weighted GRS (wGRS) were estimated. To validate the GRSs, the area under the curve (AUC) was explored using ten-fold internal cross-validation for uGRS (0.802) and wGRS (0.777). Further covariates of interest were added to the analyses, obtaining a higher predictive ability (AUC values of uGRS: 0.879; wGRS: 0.881 for BMI z-score). Furthermore, the differences between AUCs obtained with and without the addition of covariates were statistically significant (p < 0.05). Both GRSs, the uGRS and wGRS, could be useful to evaluate the predisposition to hypertension in European adolescents.

Analysis of the transformation of normative documents &#x0D; on the management of nutrition of children and adolescents: &#x0D; History and modernity (literature review)

One of the main tasks of modern society and the state as a whole is the preservation and strengthening of the health of the younger generation. Legislative documents regulating the requirements for catering for children must be strictly observed. The article considers the main managing and methodological results &#x0D; of their implementation in different periods of time in children’s educational institutions.&#x0D; The purpose of the study is to study the available archival data of regulatory documents on the management of nutrition for children and adolescents, their transformation of practical application in the historical aspect.&#x0D; The analysis of changes in requirements to normative documents on the management of nutrition of the child population according to the available archival data, data from the literature of the Soviet and post-Soviet period, published in such information sources as scientific electronic libraries: elibrary.ru, CyberLeninka.&#x0D; The study of archival regulatory and methodological documents on the management of nutrition for children and adolescents showed that the base for their development and reprinting was the changes taking place in the world, the country, the sanitary and epidemiological situation, the development of science, the industrialization of production. The management of children’s nutrition has always been considered in conjunction with environmental factors, which justified its importance in increasing the resistance of the child’s body to various adverse factors.&#x0D; Conclusion. Issues of both food safety and the assessment of the fulfillment of the norms of the physiological needs of the child in the management of nutrition in educational institutions should always remain a priority in the implementation of control and supervisory activities. Improving the legal framework, taking into account modern requirements for the management of education and upbringing of children and adolescents, catering, is aimed at preventing intestinal infections, at reducing the risk of alimentary-dependent diseases.

The relationship between the nutritional literacy level and heart health attitudes of adolescents

PurposeIt was aimed to evaluate the effect of adolescents' nutritional literacy level on their heart health attitudes. MethodsThis is a descriptive and cross-sectional study. Data from 416 adolescents were obtained in the study. The Adolescent Nutrition Literacy Scale (ANLS) and the Cardiovascular Health Behavior Scale for Children (CHBSC) were completed by participants. The adolescents' demographic information, lifestyle, and diet habits were collected. The results were analyzed using descriptive statistics and multivariable regression. ResultsThe participants' mean scores of the ANLS and the CHBSC were as 68.30 ± 8.68 and 67.55 ± 8.45, respectively. It was determined that 88.7% of the adolescents had moderate attitudes towards heart health and that there was a weak and negative correlation between the ANLS and CHBSC scores (r = −0,207; p < 0.001). It was determined that there was a statistically significant difference in ANLS and CHBSC scores in terms of gender, Body Mass Index (BMI), fast food consumption frequency, what they primarily pay attention to in food, weekly exercise frequency, the amount of daily water consumption, general health status and reading the label of packaged products (p < 0.05). It was determined that exercising, general state of health, BMI, consumption of fast food, and reading the label of packaged products were key predictors of CHBSC scores. Additionally, exercising, consumption of fast food, and reading the label of packaged products were identified as key predictors of ANLS scores. ConclusionsOur analysis suggests that higher levels of nutritional literacy are related to more positive attitudes towards heart health in adolescents. Additionally, our analysis identifies key predictors of both nutrition literacy and heart health behaviors. Practice implicationsSchool health nurses should consider the variables influencing these parameters to improve attitudes towards nutritional literacy and heart health in adolescents.

Relative validity of the Planetary Health Diet Index by comparison with usual nutrient intakes, plasma food consumption biomarkers, and adherence to the Mediterranean diet among European adolescents: the HELENA study.

The EAT-Lancet Commission proposed an evidence-based global reference diet to improve human health within planetary boundaries. Recently, the Planetary Health Diet Index (PHDI) was developed based on the EAT-Lancet recommendations and validated among Brazilian adults. However, the relative validity of the PHDI in adolescents has yet to be assessed. Thus, we aimed to evaluate the relative validity of the PHDI in European adolescents. We used cross-sectional data from 1804 adolescents (12.5-17.5years) enrolled in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study. The PHDI (0-150 points) was calculated based on dietary intake data from two non-consecutive 24-h dietary recalls. Associations between the PHDI and usual nutrient intakes, plasma food consumption biomarkers, and adherence to the Mediterranean diet were evaluated using multivariable-adjusted mixed-effects linear regression models. Higher PHDI score was associated with greater intakes of nutrients predominantly from plant-source foods, such as vegetable protein, vitamin E, and folate and with lower intake of nutrients predominately from animal-source foods, such as total and saturated fat, cholesterol, and animal protein. Furthermore, a higher PHDI score was also positively associated with plasma β-carotene, vitamin C, vitamin D, folate, and ferritin concentrations, while negatively associated with trans-fatty acids concentration. Moreover, higher PHDI was related to a greater adherence to the Mediterranean dietary pattern. The PHDI showed good relative validity among adolescents in the HELENA study. Hence, future research should assess adherence to the PHDI and long-term health outcomes.
