| Abstract |
Anemia (An) is a public health problem in South America, with iron deficiency (ID) as the main cause. In high-altitude cities, hypobaric hypoxia causes an increase in hemoglobin (Hb) levels in residents. For the diagnosis of An, Hb is measured, which is modified after erythrocyte indices (EI) measurements. There is evidence that there is an overestimation of the prevalence of An at high altitudes. To correlate serum ferritin (SF) with Hb and EI, and to determine the Hb cut-off point for predicting ID in 6-month-old infants at 3400 m of altitude. 128 infants aged 6 months at 3400 m altitude were evaluated. The SF was considered an independent variable. IE and Hb were the dependent variables. The An in the infant was defined with an Hb < 13.4 g/dl. The DH was defined by FS <12 ug/dL. Data were processed in SPSS® version 25. Spearman correlation was used for bivariate analysis. The ROC curve was constructed to determine the Hb cut-off point for ID. The highest correlation of SF was observed with mean corpuscular hemoglobin (MCH), rho = 0.449 (p < 0.001), and mean corpuscular volume (MCV) rho= 0.423 (p < 0.001). The Hb cut-off point according to SF, defining ID was 12.15 g/dL (ROC curve: 0.704; 95% CI: 0.597-0.811; p < 0.001). MCV and MCH showed a better correlation with SF. The cubic and logarithmic models were the ones that best represented these relationships, respectively. Hb < 12.15 g/dL allows diagnosing ID in 6-month-old infants at 3400 m altitude. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 29 February 2024.
All research outputs
#23,011,330
of 25,656,290 outputs
Outputs from Revista chilena de pediatría
#458
of 648 outputs
Outputs of similar age
#290,263
of 353,240 outputs
Outputs of similar age from Revista chilena de pediatría
#4
of 4 outputs
Altmetric has tracked 25,656,290 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 648 research outputs from this source. They receive a mean Attention Score of 2.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
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 353,240 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one.
