ABSTRACT

Objective: to evaluate the effect of losses during follow-up of the study “Factors associated with stunting in a cohort of children from public health facilities in the Huancavelica and Loreto regions.” Materials and methods: the cohort of children was developed to identify the causes of childhood stunting in Huancavelica and Loreto, children were evaluated at 3, 6, 9 and 12 months of age. Children born in health facilities in both regions were enrolled. Information on sociodemographic aspects, food safety, food consumption, anthropometry and hemoglobin was collected at each evaluation stage. A multiple linear regression panel model was used, with the Z-score for height-for-age of the participants as the dependent variable and loss to follow-up as the independent variable. Results: 1508 children were enrolled (748 in Huancavelica and 760 in Loreto), the losses to follow-up represented 39.7% and 26.4% in Huancavelica and Loreto respectively. During enrollment there was a higher prevalence of stunting in Huancavelica (11.8%) than in Loreto (7.7%) (P value = 0.,001). Follow-up losses did not affect HAZ (p value = 0.461 CI: -0.18; 0.08). Conclusions: the cohort study had losses to follow-up within the estimates. Follow-up losses did not affect HAZ, the indicator related.
