Abstract Content
We studied the malnutrition profiles and their association with soil transmitted helminth (STH) infections among an aboriginal tribe in transition, the Negritos. The findings between two types of Negrito communities, those in a) Inland Jungle Villages (IJV); and b) Resettlement Plan Scheme (RPS) were compared. A total of 416 Negritos participated (i.e., 149 IJV and 267 RPS). Stool samples were examined by iodine wet mount, formalin-ether sedimentation and Kato Katz for STH. Anthropometric indicators were determined and anaemia status were assessed. STH prevalence was significantly higher in IJV (91.3%) compared to RPS (83.1%) (p=0.02). However, the RPS Negritos had significantly higher helminth burden of Trichuris trichiura (mean epg:5453.8 versus IJV:3105.3; p<0.001). In addition, the prevalence of underweight, stunting, thinness and anaemia were also significantly greater in RPS (63.6%, 47.5%, 41.5%, 69.7%) versus IJV (48.7%, 38.5%, 35.0%, 64.1%; [p value: 0.03, 0.13, 0.25, 0.43]), respectively. In the IJV, we noted significant association between STH polyparasitism with underweight (adjusted odd ratio [AOR]: 3.8; p=0.01) and anaemia (AOR: 7.3; p=0.02). No significant associations were observed between STH infections with stunting and thinness. In the RPS, only underweight was highly associated with T. trichiura infection (AOR: 4.2; p= 0.01). Thus, a proper database monitoring system, good nutrition program coupled with mass anti-helminthic treatment are urgently needed especially in RPS because STH could negatively or synergistically impact the growth and learning ability especially among the young Orang Asli generation.
