BACKGROUND AND OBJECTIVE: Food security is a multifaceted issue experienced by nations worldwide. A trend currently being explored in recent studies in measuring food security at the micro level is the Dietary Diversity Score (DDS). Household Dietary Diversity Score (HDDS), a type of DDS, obtains a snapshot of the economic ability of a household, making it an effective food insecurity indicator. The objective of this study was to assess the validity of the HDDS as a tool for measuring food insecurity.

METHODOLOGY: The study employed a cross-sectional analytic design with 368 study households in Lucena City, Quezon Philippines. Household Food Insecurity Access Scale (HFIAS) and Household Mean Adequacy Ratio (HHMAR), being two of the most frequently used methods in measuring household food insecurity, were used as reference standards to assess the validity of the HDDS in identifying food insecure households. Receiver Operating Curve (ROC) Analysis was done to determine the appropriate HDDS cut-off for identifying food insecure households.

RESULTS: The areas under the curve (AUC) obtained (0.618, 0.70, 0.701, 0.743), classified HDDS as a "fair indicator" of food insecurity. HDDS of 6 was identified as the optimal score when evaluating food insecurity withconsideration of sensitivity and specificity.

CONCLUSION: In this study, HDDS was proven to be a valid measure of food insecurity. It shows the great potential of this quick assessment tool in identifying population-at-risk, which is crucial in the design of a timely and appropriate intervention to alleviate food insecurity and other nutrition and health-related problems whichmay arise.

Introduction: Health and nutrition interventions in developing countries have been linked to better thriving and survival of children. Identifying programmes with significant effect on the nutritional status of Filipino preschool children may aid in identifying impactful interventions in addressing malnutrition. This study evaluated the association between nutritional status of preschool children and government programme participation based on the 2018 Expanded National Nutrition Survey (ENNS) results. Methods: Secondary data analysis of 12,949 preschool children was performed from the 2018 ENNS. The selected data included socioeconomic, anthropometric, and self-reported household-level and individual-level government programme participation. Chi-square test for association and multiple logistic regression were conducted using Stata version 16. Results: Participation in immunisation programme, growth monitoring, household food production, and awareness and usage of iodised salt were negatively associated with at least one type of undernutrition. Consequently, participation in deworming programme was positively associated with both underweight and stunting. Regression analysis showed that preschool children who underwent growth monitoring were less likely to be stunted (OR=0.58), while those who underwent newborn screening were less likely to be underweight (OR=0.53) and stunted (OR=0.62). On the contrary, dewormed children were more likely to be stunted (OR=1.63) and those from 4Ps households were more likely to be wasted (OR=2.24). Conclusion: There is a need to re-evaluate programme strategies to maximise the benefits provided. Programmes showing significant associations with nutritional status including immunisation, growth monitoring, deworming, household food production, and awareness and usage of iodised salt should be continued and sustained with updated policies.
