ABSTRACT

Background: Malaria remains a global public health problem. Approximately 40% of the world’s population lives in more than 140 countries at risk of malaria, inc­luding Indonesia. The strategies employed to prevent and control malaria have been effective in reducing the burden of disease. Yet, as analyses of health out­comes become more refined, it is increasingly evident that poor and marginalized popu­lations might not be benefiting from investments in malaria prevention and control.  This study aimed to estimate home environment factors associated with Falciparum malaria infection in Lembata, East Nusa Tenggara.

Subjects and Method: This was a case control study conducted in Lembata, East Nusa Tenggara. A sample of 226 subjects was selected for this study, consis­ting of 113 Falciparum malaria cases and 113 controls. The dependent variable was Falciparum malaria infection. The independent variables were sunlight, dis­tan­ce to breeding place , house ventilation, use of wire net, and use of bed-net. Data on Falciparum malaria infection were taken from the medical record. The other data were collected by questionnaire. The data were analyzed by a multiple logis­tic regression.

Results: The risk of Falciparum malaria infection decreased with sunlight pene­tra­ting breeding place (OR= 0.13; 95% CI= 0.02 to 0.66; p= 0.014), distance to bree­­ding place  (OR= 0.45; 95% CI= 0.22 to 0.95; p= 0.036), house ventilation (OR= 0.18; 95% CI= 0.08 to 0.39; p<0.001), used of wire net (OR= 0.15; 95% CI= 0.04 to 0.61; p= 0.008), and use of bed-net (OR= 0.09;  95% CI= 0.02 to 0.50; p= 0.006).

Conclusion: The risk of Falciparum malaria infection decreases with sunlight penetrating breeding place, distance to breeding place, house ventilation, use of wire net, and use of bed-net.
