ILABACA M., Juan  y  ATALAH S., Eduardo. Comparasion of the prevalence and percentage of concordance between 2 methods of analysis of maternal breastfeeding. Rev. chil. pediatr. [online]. 2002, vol.73, n.6, pp.583-589. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062002000600004.

Background: The Ministry of Health measures the prevalence of breast feeding using national surveys and also by 6 monthly reviews of statistical summaries. Objective: to compare the prevalence of breastfeeding and the diagnostic concordance between the survey results and clinical medical records. Material and methods: a prevalence survey in 519 children under 12 months, and assessment of the clinical notes of the same children. Classification was according to feeding type, exclusive breast feeding (EB), predominant breast feeding (PB), complemented breast feeding (CB), formula etc. Results: a 73.4% concordance between the 2 systems was obtained with a kappa value of 0.62 (p < 0.001). The highest concordance was in EB (93.4%) and the lowest in PB (20.4%). The prevalence of EB according to the case notes was 8.5 and was 10 points higher than the prevalence obtained in he 1996-1999 surveys (p < 0.02). Conclusions: the prevalence of EB was significantly higher according to the clinical records (p < 0.01). Although there is a general agreement between the 2 methods, one cannot determine which is more precise. Standardized surveys are useful tools, with a low cost, easy to use and process and give adequate results to help decision making.
