Childhood growth stunting is negatively associated with cognitive and health outcomes, claimed to be irreversible after age 2.
To estimate growth rates for children 2 ≤ age ≤ 7 who were stunted (sex-age standardised z-score [HAZ] <-2), marginally-stunted (-2≤ HAZ ≤-1), or not-stunted (HAZ >-1) at baseline and tracked annually until age 11; frequency of movement among height categories; and variation in height predicted by early childhood height.
We used a nine-year annual panel (2002-2010) from a native Amazonian society of horticulturalists-foragers (Tsimane'; n = 174 girls; 179 boys at baseline) is used. We used descriptive statistics and random-effect regressions.
We found some evidence of catch-up growth in HAZ but persistent height deficits. Children stunted at baseline improved 1 HAZ unit by age 11, and had higher annual growth rates than non-stunted children. Marginally-stunted boys had a 0.1 HAZ units higher annual growth rate than non-stunted boys. Despite some catch up, ∼80% of marginally-stunted children at baseline remained marginally-stunted by age 11. The height deficit increased from age 2 to11. We found modest year-to-year movement between height categories.
The prevalence of growth faltering among the Tsimane' has declined, but hurdles still substantially lock children into height categories.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 May 2019.
All research outputs
#6,978,167
of 32,102,133 outputs
Outputs from Annals of Human Biology
#198
of 1,023 outputs
Outputs of similar age
#83,327
of 331,180 outputs
Outputs of similar age from Annals of Human Biology
#3
of 10 outputs
Altmetric has tracked 32,102,133 research outputs across all sources so far. This one has received more attention than most of these and is in the 73rd percentile.
So far Altmetric has tracked 1,023 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.3. This one has done well, scoring higher than 79% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 331,180 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
