BACKGROUND: Previous studies have reported an association between maternal zinc deficiency and increased risk of nonsyndromic cleft lip with or without cleft palate (NSCL/P) in offspring. A high prevalence of zinc deficiency and a high prevalence of NSCL/P have been reported in Ecuador. We postulated that mothers of infants with NSCL/P may have lower serum zinc levels than women from the general population. METHODS: A case series study was conducted from November 2013 to July 2016. Thirty-five healthy mothers of infants with NSCL/P were selected during surgical missions conducted by Operación Sonrisa Ecuador. A single blood sample along with pertinent medical history was collected during personal interviews after 3.6 months postpartum. The prevalence of plasma zinc concentration (PZn) deficiency among the participants was determined and analyzed along with the prevalence of PZn deficiency in Ecuadorian women of reproductive age from the general population. RESULTS: The mean PZn was 11.47 µmol/dm3 . The prevalence of PZn deficiency among the participants was 31.4% (95% CI: 17.1-48.6) and differed significantly from the prevalence of zinc deficiency observed among women from the general population (G2 = 8.66; p < .05). CONCLUSIONS: The results showed that the prevalence of PZn deficiency is lower in a cohort of healthy mothers of infants with NSCL/P than in women from the general population in Ecuador. More studies are required to confirm these findings and evaluate other factors related to NSCL/P pathophysiology in the Ecuadorian population.
