Background and objectives: Guatemala currently faces a double burden of malnutrition with high incidence of stunting and increasing rates of childhood obesity. Stunting can originate in utero or immediately after birth. Linear growth status has been studied in various locations and communities throughout and country. There is, however, not much information about Livingston, a village on the Caribbean coast of Guatemala. In this study, we sought to examine the differences in body size between Garifuna (Afro-Caribe) and non-Garifuna (Mayan and Ladino) children and adolescents through anthropometric measurement.
Methods: Anthropometric measurements (weight, height and armspan length) of Garifuna (n = 121) and non-Garifuna (n = 84) youths were compared. We measured the weight of each subject to the nearest tenth of a kilogram using a calibrated, digital bathroom scale placed on a level surface. The standing height of each subject was measured to the nearest centimeter with a measuring-tape stadiometer. The armspan of each subject was measured to the nearest centimeter using an inflexible measuring stick. BMI-percentiles-for-age of individuals was obtained using the CDC child/adolescent on-line BMI calculator We calculated the armspan-to-height ratio. Mann Whitney U test was used to compare distributions across groups and the association between variables was tested with the Spearman rank-order correlation coefficient.
Results: The overall (n=205) Spearman rank-order coefficient rho for height vs armspan was 0.958 (pGarifuna adolescents had greater median height measurement, 159 vs 149 cm, respectively, than the non-Garifuna and armspan length, 162 vs 150 cm, respectively. Median weight in the former group (48.4 kg) was greater than (47.0 kg) in the latter, but median BMI percentile, 50.0 vs 65.5, respectively, was a lower among the Afro-Caribe than in non-Garifuna youth. All inter-group differences were at p
Conclusion: Garifuna children and adolescents were longer than non-Garifuna, as shown by the difference in both height and armspan. Garifuna children and were significantly heavier by absolute weight (in kg), but correspondingly leaner by relative weight (as shown by BMI).
