Eye screening can be used to perform anemia screening and treatment in adolescent girls using ToucHb.

PURPOSE: Anemia is common in adolescent girls. Apprehension while drawing blood to estimate hemoglobin concentration is a barrier for confirming anemia. ToucHb, a noninvasive instrument that estimates the hemoglobin by taking an image of the exposed conjunctiva, was used during eye screening to help diagnose and treat anemia.

METHODS

ToucHb was used during secondary school eye screening and during house-to-house eye screening to estimate the hemoglobin concentration in the body. Each of the girls was distributed a packet of 60 tablets of ferrous and folate and a tablet of albendazole. They were followed up after 3 months.

RESULTS

Exactly 1511 municipal school girls aged 10-19 years (mean 12.9; standard deviation [SD] 1.64) were examined. Of them, 949 (62.8%) had hemoglobin of ≤9 mg%. Among those girls with hemoglobin ≤9 mg%, the mean (SD) during the initial and follow-up examinations was 6.1 (1.4) and 9.6 (1.03), respectively, by paired t-test (P < 0.001). Another 588 girls (average age 14.4 years, SD 1.2) had their eyes examined and hemoglobin estimated during a house-to-house eye screening. Of them, 116 (19.7%) had hemoglobin level of ≤9 mg%. Their pre-Hb was 7.9 (SD 1.05) on average and after 3 months, it was 9.6 (SD 1.02). Among those girls with hemoglobin ≤9 mg%, the mean (SD) during the initial and follow-up examinations was 6.2 (1.4) and 7.9 (1.1), respectively, by paired t-test (P < 0.001).

CONCLUSION

ToucHb was useful to diagnose anemia while doing eye screening and to ensure its treatment. Anemia diagnosis and management would enhance the health of adolescent girls.
