P-97: Role of Micronutrtients in HIV/AIDS Pathogenesis


Objective: An investigation of dietary patterns and selenium levels in diets of smallholder farmers and agricultural soils was carried out in Pala Sub-location. Materials and Methods: In this study a total of 386 respondents selected randomly were interviewed in the four villages in the sub-location. The data was coded and analyzed by SPSS program while food and soil selenium levels were analyzed by AAS. Results: It was shown that most of the respondents (61%) were small holder Farmers and Fishermen {X2 (1, n=386) p<0.000}, and that most of them (91.2%) had up to college level education {X2 (1, n=386)p<0.000}, while the number of males were only slightly more than the females{X2 (1, n=386) p=0.263} and 83.5% of respondents were married {X2 (1, n=386) p=0.000}. The investigation also revealed that most of the respondents own between 0.25 and 5 acres {X2 (1, n=386) p= 0.000} and that most of them plant maize (82.6%), millet (55.4%), beans (37.6%) and sorghum (21.2% 0 while they also kept goats (48.2%), cows (46.9%) and chicken (42.7%). The study showed that adults take on average 2.68 meals a day (n=382, SD= 0.603) while children take 3.02 meals a day (n=386, SD=1.031) a day, and that in most households (82.6%) food is prepared by the women {X2 (1, n=386) p=0.000} and further that 50% of foods eaten in that community are purchased {X2 (1, n=386) = 0.1818, p=0.6698}.The foods eaten by 75.2% of the respondents were fish- Tilapia/Nile perch , 75.2% eat sorghum/millet, 64.1% vegetables and that both children and adults eat same types of food and further that traditional foods which have become extinct are mainly vegetables (46%). The study established that selenium levels in foods eaten in Pala sub-location varies, with traditional vegetables having higher levels of selenium, for example,Achak Achak (148.5 mg/kg) spider web(121.5mg/kg), cow pea (21.97 mg/kg), while Omena (51mg/kg) Nile perch (0), tilapia(0) red millet/sorghum 19.97 mg/kg, and white/brown sorghum (0).The study showed that there is inverse relationship between foods eaten and selenium levels {RR=1.21, p= 0.000} with foods eaten by 75.2% of respondents (Nile perch/Tilapia) having no detectable selenium . Four soil types identified in the study area had varying selenium levels with pleat loam (13.3 mg/kg) sandy loam (10.7 mg/kg), clay (2.8 mg/kg) and loam (4.8 mg/kg). Conclusion: From the study it would be recommended that to increase selenium levels in the diet, more production and consumption of traditional vegetables should be encouraged.
