Insights
Machine learning models show promise in predicting childhood malnutrition using Demographic and Health Surveys data. These AI tools offer moderate to good performance for identifying at-risk children under five.
Area of Science:
- Public Health
- Data Science
- Pediatrics
Background:
- Childhood malnutrition is a critical global health issue.
- Demographic and Health Surveys (DHS) offer valuable child health data.
- Assessing machine learning (ML) applications in DHS data for malnutrition prediction is essential.
Purpose of the Study:
- To conduct a meta-analysis on machine learning applications in DHS data for predicting childhood malnutrition.
- To evaluate the performance of ML models in identifying malnutrition in children under five years.
Main Methods:
- Systematic literature search of PubMed, Embase, and Scopus databases (January 2024).
- Inclusion of studies using ML algorithms on DHS data for child malnutrition prediction.
- Quality assessment using PROBAST and meta-analysis using Review Manager 5.4.
Main Results:
- 11 studies (2019-2023) were included, with a focus on Bangladesh.
- Pooled accuracy for ML models predicting stunting: 68.92% (10 studies).
- Pooled accuracy for ML models predicting wasting: 84.39% (3 studies).
- Pooled accuracy for ML models predicting underweight: 73.60% (4 studies).
Conclusions:
- ML models demonstrate moderate to good performance in predicting childhood malnutrition.
- DHS data, when analyzed with ML, can be a valuable tool for public health initiatives.
- Further research can refine ML models for more accurate malnutrition prediction.
Background:
Childhood malnutrition remains a significant global public health concern. The Demographic and Health Surveys (DHS) program provides specific data on child health across numerous countries. This meta-analysis aims to comprehensively assess machine learning (ML) applications in DHS data to predict malnutrition in children.
Methods:
A comprehensive search of the peer-reviewed literature in PubMed, Embase, and Scopus databases was conducted in January 2024. Studies employing ML algorithms on DHS data to predict malnutrition in children under 5 years were included. Using PROBAST (Prediction model Risk Of Bias Assessment Tool), the quality of the listed studies was evaluated. To conduct meta-analyses, Review Manager 5.4 was used.
Results:
A total of 11 out of 789 studies were included in this review. The studies were published between 2019 and 2023, with the major contribution from Bangladesh (n = 6, 55%). Of these, ten studies reported stunting, three reported wasting, and four reported underweight. A meta-analysis of ten studies reported a pooled accuracy of 68.92% (95% CI: 66.04, 71.80; I2 = 100%) among ML models for predicting stunting in children. Three studies indicated a pooled accuracy of 84.39% (95% CI: 80.90, 87.87; I2 = 100%) in predicting wasting. A meta-analysis of four studies indicated a pooled accuracy of 73.60% (95% CI: 70.01, 77.20; I2 = 100%) for ML models predicting underweight status in children.
Conclusions:
This meta-analysis indicated that ML models were observed to have moderate to good performance metrics in predicting malnutrition using DHS data among children under five years.
