Ght for age z-scores have been considerably reduce than 0 (p 0.001) and stunting was prevalent (42.9 ). Zinc deficiency was extremely prevalent in Cambodia (92.eight ), whereas zinc deficiency was discovered in only 12.two in the Cuban young children. Prevalence of STH infections was eight.four and 16.8 for Cuba and Cambodia, respectively. Inside the Cuban study, essentially the most frequent STH infections have been A. lumbricoides (61.four ) and T. trichiura (36.eight ), even though hookworm (97.0 ) was the predominant STH infection in Cambodia. In both populations, most STH infections were of light intensity (Table 1). Table 1.

Associations between Height for Age, Zinc and STH Infection STH infected Cuban youngsters had on average lower height for age when compared with their MicroRNA Activator Species uninfected peers (Table two), and regression analysis showed a important damaging association between STH infection and height for age (Table 3). The association involving hair zinc and height for age was not important but did show a optimistic trend. In Cambodia, plasma zinc, but not STH infection, was considerably linked with height for age (Table 3). In each populations, STH x zinc interaction terms weren’t statistically substantial. On the other hand, when stratifying for STH infection, within the uninfected Cuban youngsters a significant, constructive association (aB-0.471, p = 0.033) was located amongst hair zinc and height for age.
