Behavior-Based Malaria Incidence Prediction Model in the Hanura Community Health Center Work Area, Pesawaran Regency, Lampung, Indonesia

Malaria is an infectious disease caused by the Plasmodium parasite and transmitted through the bite of an infected female Anopheles mosquito. This disease remains a public health problem in the working area of ​​the Hanura Community Health Center, Pesawaran Regency, Lampung, Indonesia. Behavioral factors and home protection conditions are thought to play a role in increasing the risk of malaria, such as the use of mosquito nets, mosquito repellent, wire mesh, and activities outside the house at night. This study aims to analyze behavioral factors that influence the incidence of malaria in the working area of ​​the Hanura Community Health Center, Pesawaran Regency, Lampung, Indonesia. This study used an observational analytical design with a case-control approach conducted in November 2025–January 2026. The study sample consisted of 113 case groups and 113 control groups selected using proportional random sampling techniques. Data were obtained through questionnaires and analyzed using the Chi-Square test with a significance level of α = 0.05. The results showed that the use of mosquito nets had a significant relationship with the incidence of malaria (p-value = 0.016; OR = 2.00; 95% CI = 1.17–3.42), the use of mosquito repellent (p-value = 0.002; OR = 2.95; 95% CI = 1.53–5.70), and the use of wire netting (p-value = 0.008; OR = 2.12; 95% CI = 1.25–3.61). Meanwhile, activities outside the house at night did not have a significant relationship with the incidence of malaria (p-value = 0.893). Behavioral factors and physical protection of the house play an important role in the incidence of malaria. The use of mosquito nets, mosquito repellent, and wire netting has been shown to be associated with a reduced risk of malaria, so that sustainable prevention efforts are needed through improving healthy living behaviors and protecting the home environment.
