Nutritional status in the first thousand days of life (1000 HPK), which is 270 days during pregnancy and 730 days in the baby's first life, is a critical period because the consequences are permanent and irreparable. The period of 1000 HPK was so important that the World Bank (2009) referred to it as the “Window of Opportunity.” That is, the opportunity (“opportunity”) and “target” to improve the quality of human resources of future generations turned out to be narrow (“window”). The 1000 HPK is a food insecurity group including pregnant women, nursing mothers, and children under two years old. Thus the nutrition program policy is focused on this group of 1000 HPK. Since 2010 in the international world known sun movement (Scaling Up Nutrition) and in Indonesia, this effort developed into a National Movement conscious nutrition to accelerate nutrition improvement in the first 1000 days of life (Movement 1000 HPK).1 Specific indicators to assess the achievement of specific nutritional interventions include the protection of pregnant women against iron deficiency, folic acid, and chronic energy and protein deficiency (KEK), protection of protein adequacy in nursing mothers, protection of children under two years of breast milk containing enough protein and iron, and treatment of diarrhea.1,2

Stunting is one of the nutritional problems faced in the world, especially in poor and developing countries.3 Stunting becomes a problem because it is associated with an increased risk of pain and death, suboptimal brain development so that motor development is late and mental growth is inhibited. Some studies show the risks associated with stunting include decreased academic achievement, increased risk of obesity, more susceptibility to non-communicable diseases, and increased risk of degenerative diseases. Over the past 20 years, the handling of stunting problems has been prolonged. Globally, the percentage of children stunted by growth has declined by just 0.6 percent annually since 1990. Who proposes a global target of reducing stunting incidence in children under the age of five by 40% by 2025, but predicted that only 15-36 countries would meet that target.

Prospective cohort research in Jamaica, conducted in the 9–24 month age group, followed by psychological development when 17 years old, found that adolescents who stunted growth had higher levels of anxiety, depressive symptoms, and lower self-esteem than adolescents who were not stunted by growth. Children who stunted their growth before the age of 2 had worse outcomes in their emotions and behaviors in late adolescence.4 Therefore stunting is a predictor of poor quality of human resources, affecting the nation's potential.3 Stunting is a form of growth faltering due to the accumulation of nutritional insufficiency that lasts a long time from pregnancy to the age of 24 months.5,6 This situation is exacerbated by the incomparable pursuit of adequate catch-up growth.5,7 Indicators used to identify stunting toddlers are based on the height by age index (TB/U) according to whom child growth standard with stunting criteria if the value of z score TB/U < -2 Standard Deviation (SD).8

Technological advances have now undergone such rapid development, and one example is application. This product is a multifunctional product with all its sophistication which can help people in various ways. The internet can help many human jobs to make people more productive and make human work more effective and efficient. The results of research conducted by Muhammad Azhar Hairuddin in 2017 showed that designing and creating an application to monitor the development of nutritional status and health of infants and toddlers using Android-based Anthropometry method to help reduce the percentage of malnutrition and malnutrition as well as the death rate of children under 5 years old in Indonesia.9 This is evidenced by the results of White Box and Black Box testing and as well as the dissemination of questionnaires to 20 target users, namely to mothers of infants and toddlers then 10 target users of health workers and medical personnel. White Box testing results show that various methods of coding can already run well following the theory. Black Box testing results show that functionally the functions, inputs, and outputs of the software are following the required specifications, while based on the results of the questionnaire from 32 respondents from parents of infants and toddlers totaling 21 people stated that 90.6% stated that it had met the expectations of users, then from health/medical personnel from 11 respondents, a percentage of 86.7% assumed that the software was following the Method of Anthropology.

This study looked for journals used in the literature review, journals used in literature review obtained through the database of international journal providers such as Google scholar, PubMed, and Proquest. Researchers wrote the appropriate keywords, namely nutritional status of 1000 HPK, stunting, and application. The year limit used is ten years from 2010 to 2020.

A total of 20 journals have been studied, and there are 8 research journals used in the literature review, namely the application to measure the growth, nutritional status, and health of mothers and toddlers. Overall this research article helps monitor parents and health workers in terms of services in the first 1000 days of life (Table 1).

The results of the journal review obtained that the application of nutritional status monitoring using anthropometry standards, anthropometry itself is a standard of measurement of growth by calculating weight, length or height, and head circumference. Some have the ability or features to record patient demographic data, results of maternal and child health development examinations, vaccine drugs, immunizations, and display graphs/tables of maternal and child health development periodically. The designer and implementing of nutrition status monitoring applications and recording the health development of mothers and children help midwives, posyandu cadres, mothers, or mothers-to-be obtain excellent and correct information because the application is easy.

From some of the results of this study, there is a significant influence between monitoring applications to improve nutritional status. It is expected that the application of nutrition status monitoring can run optimally and produce quality data/information to overcome related problems in 1000 HPK, especially stunting.

From some of the above journals can be concluded that the use of development monitoring application, nutritional status, and health of mothers and children in the service of 1000 HPK facilitates parents, midwives, and other health workers in working to monitor the development of pregnant women and the growth of infants and toddlers for stunting prevention.
