Determinant factors of the improvement of nutritional status (based on height-for-age index category) in children during the covid-19 pandemic: a cohort study of children's growth and development in bogor

The COVID-19 pandemic is predicted to trigger a global economic and food supply crisis, which further affects children's nutritional status as a vulnerable group. This study aimed to observe alterations in nutritional status before and during the COVID-19 pandemic (during 2019-2021) and determinant factors involved in the improvement of nutritional status (based on the height-for-age Z-score (HAZ) index category) during the COVID-1 9 pandemic. The findings were intended as evidence-based suggestions for policy formulation concerning the improvement of child nutritional status and stunting reductions. This study was part of a cohort study of children's growth and development conducted by National Institute of Health Research and Development (NIHRD) in Bogor city-Indonesia. The analysis was conducted on 565 children under five in 2019 with height measurement data in 2019 and 2021, environmental conditions, parental education, consumption habits, and social assistance. Children were classified as having an improved nutritional status if the HAZ category increased in 2021 compared to 2019. In addition, multiple logistic regression analyses were performed to predict determinant factors involved in improving the child's nutritional status. In this study, 17.5% of children had improved nutritional status, and 79.3% had a steady nutritional status. However, there were 3.2% of children with decreased nutritional status. Model factors determinant related to improved nutritional status includes consumption more than once per week of red meat (adjusted odds ratio (aOR) = 2.15; 95% confidence interval (CI): 1.06-4.35, p=0.034), milk consumption more than once per week (aOR = 1.56; 95% CI: 0.89-2.74, p=0.119), and age under 5 years old (aOR = 1.86; 95% CI: 1.14-3.15, p=0.016). Children under five years old, the consumption of red meat and milk more than once a week have the opportunity to improve nutritional status (by height-for-age index) in children.
