Background: Climatic change is an inescapable fact that implies alterations in seasons where weather occurrences have their schedules shift from the regular and magnitudes intensify to more extreme variations over a multi-year period. Southeast Asia is one of the many regions experiencing changes in climate and concurrently still has endemicities of malaria. Given that previous studies have suggested the influence of climate on malaria’s vector the Anopheles mosquitoes and parasite the Plasmodium group, this study was conducted to review the evidence of associations made between malaria cases and climatic variables in Southeast Asia throughout a multi-year period. Methods: Our systematic literature review was informed by the PRISMA guidelines and registered in PROSPERO: CRD42022301826 on 5th February 2022. We searched for original articles in English and Indonesian that focused on the associations between climatic variables and malaria cases. Results: The initial identification stage resulted in 535 records of possible relevance and after abstract screening and eligibility assessment we included 19 research articles for the systematic review. Based on the reviewed articles, changing temperatures, precipitation, humidity and windspeed were considered for statistical association across a multi-year period and are correlated with malaria cases in various regions throughout Southeast Asia. Conclusions: According to the review of evidence, climatic variables that exhibited a statistically significant correlation with malaria cases include temperatures, precipitation, and humidity. The strength of each climatic variable varies across studies. Our systematic review of the limited evidence indicates that further research for the Southeast Asia region remains to be explored.

The Relationship Between Climate Change and Indonesia's Malaria Burden

Malaria has been with humans for thousands of years. It is caused by parasites of the genus Plasmodium that are transmitted by female Anopheles mosquitoes. The variation of global malaria distribution has recently been associated with changing climatic conditions, such as temperature, precipitation, windspeed, and humidity. One country where malaria transmission remains high in select subnational areas is Indonesia. Founded upon previous findings on the relationship between climate change and malaria, this research delves into the same equation for the case of Indonesia through a structural model which overcomes the variable co‐interaction between temperature, precipitation, windspeed, and humidity. This study follows an ecological study design with yearly longitudinal data (t = 20, n = 432). The method of analysis employed is a structural equation modelling approach for panel datasets with an output of factor loading values to determine association levels. The independent variable is a climate change construct of maximum, minimum, and average values from temperature, windspeed, relative humidity and precipitation as observables taken from the NASA Langley Research Center (LaRC) POWER Project. Meanwhile, the dependent variable is yearly malaria incidence rates at the city and regency level extracted from the Malaria Atlas Project dataset. All variables are standardized to account for unit differences. The SEM results indicate a standardized relationship between a latent climate variable with malaria incidence in a statistically significant manner. However, differences in coefficient directions between the three models indicate that the relationship remains elusive. In the maximum value model, a standard deviation increase in the climate change construct from its mean is associated with a 0.04 standard deviation increase in malaria incidence from its own mean (p < 0.001). On the other hand, in the minimum and average value models, a standard deviation increase in limate change construct from its mean is associated with a 0.12 and 0.09 standard deviation decrease of malaria incidence from its own mean respectively (p < 0.001). Although statistical significance was established across all models which indicated relatively good fit across select indices, the standardized coefficient values presented in this study suggest that any associations between long term climatic variations (measured by yearly data) and malarial incidences are modest at best. The results of the structural equation models also indicate that other factors are at play when it comes to malaria case variations—as explained by the residual terms across all models.
