We conducted a longitudinal study among 827 pregnant women in Nyanza Province, western Kenya, to determine the effect of earth-eating on geohelminth reinfection after treatment. The women were recruited at a gestational age of 14–24 weeks (median: 17) and followed up to 6 months postpartum. The median age was 23 (range: 14–47) years, the median parity 2 (range: 0–11). After deworming with mebendazole (500 mg, single dose) of those found infected at 32 weeks gestation, 700 women were uninfected withAscaris lumbricoides, 670 withTrichuris trichiuraand 479 with hookworm. At delivery, 11.2%, 4.6% and 3.8% of these women were reinfected with hookworm,T. trichiuraandA. lumbricoidesrespectively. The reinfection rate for hookworm was 14.8%, forT. trichiura6.65, and forA. lumbricoides5.2% at 3 months postpartum, and 16.0, 5.9 and 9.4% at 6 months postpartum. There was a significant difference in hookworm intensity at delivery between geophagous and non-geophagous women (P = 0.03). Women who ate termite mound earth were more often and more intensely infected with hookworm at delivery than those eating other types of earth (P = 0.07 andP = 0.02 respectively). There were significant differences in the prevalence ofA. lumbricoidesbetween geophagous and non-geophagous women at 3 (P = 0.001) and at 6 months postpartum (P = 0.001). Women who ate termite mound earth had a higher prevalence ofA. lumbricoides, compared with those eating other kinds of earth, at delivery (P = 0.02), 3 months postpartum (P = 0.001) and at 6 months postpartum (P = 0.001). The intensity of infections withT. trichiuraat 6 months postpartum was significantly different between geophagous and non-geophagous women (P = 0.005). Our study shows that geophagy is associated withA. lumbricoidesreinfection among pregnant and lactating women and that intensities built up more rapidly among geophagous women. Geophagy might be associated with reinfection with hookworm andT. trichiura, although these results were less unequivocal. These findings call for increased emphasis, in antenatal care, on the potential risks of earth-eating, and for deworming of women after delivery. [ABSTRACT FROM AUTHOR]
