Abstract

Public health in coastal areas is a crucial aspect of a nation's development but faces unique challenges due to geographical, demographic, and environmental factors. This study seeks to analyze the factors influencing the Health Development Index (HDI) in coastal areas using the Structural Equation Modeling (SEM) approach with the Partial Least Square (PLS) method for a small sample. The analyzed variables include Environmental Health, Health Behavior, Health Services, Poverty Status, and the HDI, as well as their influence on Health Status. This study utilizes secondary data from the 2018 Riskesdas report and BPS publications in the southern part of Sumatra. The analysis results show that Environmental Health has a significant effect of -0,45 and Health Behavior has an effect of -0,30 on Health Status. However, Health Services, Poverty Status, and HDI do not show significant effects on Health Status. By gaining a deeper understanding of the determinants of IPKM in coastal areas, this study is expected to contribute to the development of more targeted and effective health policies. The PLS-SEM approach used in this study is also expected to serve as a reference for other researchers in applying structural models to small samples.

Abstract

A method that can be used if there is a spatial factor and if overdispersion happens in a count data is Geographically Weighted Zero-Inflated Poisson Regression (GWZIPR). This research aimed to analyze the number of malaria cases in every regency/city of Sumatra Land using the GWZIPR method and distribution mapping of factors affecting the number of malaria cases in Sumatra Land. Data involved in this research was the number of malaria cases as the response variable and the predictor variable as a percentage of households that have access to proper sanitation, a percentage of households that have access to proper water resources, and a percentage of the number of public health centers. The results were for each area which had distinctive models based on significant variables. The distribution mapping of factors affecting the number of malaria cases in every regency/city was commonly divided into three groups based on significant variables on ln and logit models. The mapping did not shape a spreading pattern or each regency/city in that group because the geographical locations were close to each other. GWZIPR method in this research was better than the ZIP Regression method because it produced the least AIC value.
