- Abstract
Objective: To estimate several risk factors related to malaria at Llochegua (Ayacucho, Peru) in 2003. Material and methods: Randomized case-control study, matched by age and sex; considering 95% of significance, beta error 0.05 and ratio1.1, a sample of 55 cases was calculated. The following risk factors were included: Number of persons at home, cleaning of house, daily shower, use of bednets, adequate use of bednets, vector exposition between 18.00 and 21.00 hours, and home distance > 200 m to stagnant water source. Results: Adequate use of bednets (OR= 0.116; IC 95% 0.033-0.342), home distance > 200 m to stagnant water source (OR= 0.112; IC 95%: 0.031-0.334), are protective factors. Logistic regression showed that those who use bednets adequately had 85% less probability to get malaria compared with those who don't (p=0.001; IC 95%: 0.052-0.441), independently from home distance to stagnant water source, house cleaning and use of bednets. Those who live closer to stagnant water source had 6,6 more probability to have malaria (p=0.001; IC 95%: 2.247-19.506); independently of use of bednets, cleaning house and adequate use of bednets. Conclusion: Home distance > 200 m to stagnant water source and adequate use of bednets are predictive factors to prevent disease.
