Determinants of child stunting in the dryland area of East Nusa Tenggara Province, Indonesia: insights from a national-level survey

Stunting remains a critical public health issue in Indonesia, particularly in the province of East Nusa Tenggara. This region, characterized by its archipelagic dryland geography, has reported the highest prevalence of stunting among children under five from 2007 to 2021. The study aimed to examine the relationship between various characteristics of children under five and household factors with the occurrence of stunting. This observational study, with a cross-sectional design, used secondary data from the 2021 Indonesian Nutrition Status Survey, covering 7,835 children under five. We analyzed the data to identify patterns and relationships, using univariate analysis to display percentage distributions and bivariate analysis through multiple binary logistic regression tests. The results of the multiple logistic regression test showed that indicators of family characteristics such as age, gender, low birth weight, body length, possession of birth certificates, and receiving complementary feeding were all related to stunting. Additionally, household factors such as toilet type, National Health Insurance coverage, ownership of a Prosperous Family Card, and residential area were significant determinants. Factors contributing to stunting in dryland areas include a range of elements from both family characteristics-such as age, gender, birth certification, low birth weight, and initial body length, to the introduction of supplementary feeding-and household indicators, including the use of specific types of latrines (Plengsengan and Cemplung types without covers), health insurance coverage, possession of Prosperous Family Cards, and the family's residential area.

Path analysis model for preventing stunting in dryland area island East Nusa Tenggara Province, Indonesia

BACKGROUND

The problem of stunting is still a fundamental problem in Indonesia's human development. East Nusa Tenggara Province is an archipelago dryland area where in 2007-2021 it has contributed to the highest number of stunting children prevalence in Indonesia. This study aims to determine the relationship of variables in individual, household and district level with the prevalence of stunting.

METHODS

This type of research is observational study with a cross sectional design. This study used individual secondary data from the Indonesian Nutritional Status Survey in 2021 consisting of 7,835 toddlers and National Social Economics Survey 2021.

RESULTS

This research found that both specific & sensitive intervention programs had an influence in accelerating the decline in stunting prevalence (higher score on Z Score). Results also revealed the positive influence of the food access variable on nutritional intake. The results of the path analysis test showed that sensitive intervention program variables have a positive effect on food access variable and environmental variable (environmental sanitation) such as the habit of open defecation and healthcare. There was significant relationship on disease history, environment and intake to Height for Age (HAZ) score.

CONCLUSIONS

In conclusion, direct and indirect factors have important roles to prevent stunting. Sensitive and specific intervention program, food access, macro determinants and environment are the indirect indicators which contribute significantly to the stunting. The risk of children under five years old experiencing malnourished nutritional status increases with a history of infectious disease (diarrhea, ARI, worms). The risk of children under five years experiencing malnourished nutritional status decreases with adequate nutritional intake. It is hoped that there will be a special model of stunting control interventions at the individual level and at the family, household and district level that are integrated and of high quality through multisectoral cooperation in the dryland areas of the islands of East Nusa Tenggara Province.
