Linear growth retardation in Zanzibari school children.
This paper describes the longitudinal changes in height and weight of children in school grades 1-3 on Pemba Island, Zanzibar, a poor rural population in which parasitic infections and anemia are highly prevalent.
Heights and weights of children were measured at base line, and 6 and 12 mo later, and were compared with U.S. reference data.
At base line, the prevalence of height-for-age Z-score<-2 rose from 14% in 7-y-old children to 83% in 13-y-old children.
Prevalence of weight-for-age Z-score<-2 in children<10 y was ~10% or less.
Median 6-mo height increments for Pembian boys were around the 5th percentile at age 8 and around the 10th percentile from age 9 to 13 y. Height increments for girls improved from below the 25th percentile to above the median in this age range.
Based on the longitudinal yearly gains observed, boys accumulate a height deficit of 11.9 cm and girls 8.5 cm, relative to the reference population.
In multivariate analyses, a small part of the variability in growth increments was explained by ascariasis and anemia (for weight gain) and schistosomiasis (for height gain).
A review of other growth data from rural African Bantu populations provides supporting evidence that stunting occurs in older as well as younger children.
It has been controversial whether school-based health and nutrition interventions could induce catch-up growth in already stunted children. (...)
