Introduction: WHO recommends the evaluation of palmar pallor as an indication of anemia in IMCI. The purpose of this study was to determine the validity and inter-observer agreement of pallor in the detection of anemia in healthy children under 2 years of age.

Methods: Healthy children aged 6 to 24 months (n=141) who admitted to our Well Baby Clinic were assessed for the presence of pallor in 3 anatomic sites (palm, conjunctiva, buccal mucosa) by two observers (a certificated senior pediatrician and a pediatric resident). All observations were made without information of the children¡¯s hematological status or of another observer¡¯s assessment. Then blood examination was done for hemoglobin level. Exclusion criteria included presence of acute or chronic illness and treatment for anemia during the 3 months preceding the investigation. Children with hemoglobin level < 11 g/dL were defined as anemic. 

Results: The mean age was 7.9 ¡À 2.8 mo; 71 (50 %) were boys. A total of 33 (23.4 %) children had anemia according to blood samples. Palmar pallor alone had the highest sensitivity to detect anemia. With multivariate analysis, palmar pallor was significantly associated with anemia. The inter-observer agreement was highest for pallor of buccal mucosa (kappa scores = 0.64), lowest for palmar pallor (0.49).

Sites                              Sensitivity*     Specificity*    PPV*

Palm                             72-45             75-86             48-50

Buccal mucosa               18-12             93-96             46-50

Conjunctiva                    45-24             86-79             50-42

All                                12-12             98-97             67-57

Palm or conjunctiva        73-46             90-86             48 -50

*The first value is of senior and the second value is of resident

Conclusion: Therefore this examination is valid only for senior pediatrician. Palmar pallor is found to be sensitive and spesific but when only used by senior pediatrician in this study. Conjunctiva and buccal mucosa pallor has no value.
