This study aims to determine the relationship between environmental factors and nutritional status with malaria incidence in the Kuala Bhee Health Center Work Area, West Aceh Regency. This study uses a case-control or retrospective study design. The case group was recorded as malaria patients based on registration data at the Kuala Bhee Health Center, Woyla District, Aceh Regency and resided in the working area of the Kuala Bhee Health Center Woyla District, West Aceh Regency. At the same time, the controls were all people who were declared free of malaria. The results showed that the presence of livestock cages and standing water had a significant relationship with malaria incidence. It is recommended that the public avoid activities outside the home at night by reducing the frequency of going out or not leaving the house during active hours of biting malaria vector mosquitoes, cleaning livestock cages and eliminating puddles around their homes.

Journal of Nutrition Science, 2(2), 1-4 Introduction Malaria is one of the main causes of death in many developing countries, especially children and pregnant women, as the main easily infected group (Sembel, D, 2009). Malaria is a tropical disease which until now is widespread in the tropics and subtropics, a disease caused by parasites of the genus Plasmodium which is transmitted through the bite of the Anopheles mosquito is still found in almost all parts of the world, at least around 2.3 billion or 41% of the world's population. At the risk of contracting malaria (Prabowo, A, 2008). The incidence of malaria is supported by environmental conditions such as poor housing and poor sanitation, which then becomes a factor related to malaria transmission. It provides a suitable environment as a resting place and breeding place for malaria-carrying mosquitoes (Saikhu, 2007). Malaria vectors' place and time distribution are influenced by topography, temperature, rainfall, land use, migration, and forest destruction (Bretas, 1996). The failure of the eradication program also causes the increasing malaria epidemic. (Mouchet, 1998). Malnutrition is responsible for more than 50% of deaths each year in developing countries.
