Associated factors for lymphatic filariasis in Beluran, Sabah
Nur Dalila Zakaria1, Richard Avoi2.
Introduction: : Lymphatic filariasis is a public health problem in Malaysia. In sub-district Tangkarason, Beluran the nine rounds of Mass Drug Administration (MDA) do not seem to work in reducing the microfilaria (Mf) prevalence below the 2% threshold that the World Health Organization (WHO) recommends for stopping MDA. The study aims to identify possible factors contributing to the transmission of lymphatic filariasis in the area. Methods: A total of 244 individuals from seven high risk localities, whom between the age of 19 and 99-year-old, were interviewed and tested for lymphatic filariasis antibody. The associated factors were analyzed using Chi-square test (Fisher exact test where applicable) and odds ratio (OR), and adjusted odds ratio (AOR) was estimated using logistic regression. Re-sults: The median age was 40-year-old (interquartile range: 30-53). The prevalence of brugian filariasis in the studied population was 31.1% (95% CI 0.25, 0.37). Prevalence of brugian filarial infection is higher in males than in females (34.6% vs. 27.4%, P = 0.219); and in older adults (≥ 56-year-old) than in young-and-middle-aged adults (46.3% vs 26.8%, P = 0.006). The older group is 2.4 times at higher odd of contracting the disease than the younger adults (95% CI 1.26, 4.38; P = 0.007). The prevalence of brugian filarial infection is higher among those who never receive pro-phylaxis treatment compared to those who had received medications (48.5% vs 28.4%, p = 0.021). Those who had received prophylaxis treatment have about 60% reduction in odd of lymphatic filariasis infection (OR 0.42; 95% CI 0.20, 0.89; P = 0.023). The proportion of the studied population who has outdoor jobs is 52.9%. The prevalence of brugian filarial is higher in this group compared to those with indoor jobs (38.0% vs 23.5%, p = 0.015). The older age group was significantly associated with brugian filarial infection after adjusting for other factors (AOR 3.20; 95% CI 1.63, 6.32). Conclusion: The older adults (≥ 56-year-old), those who never involved in MDA and those with outdoor jobs are associated with lymphatic filariasis infection in Beluran.
