Abstract

Introduction.- The breast-feeding and its relation to cancer are uncertain. The majority of studies show a protective association when breastfeeding is exclusive, at least the first six months.

Objective.- To determine the association between a history of non-exclusive breastfeeding in the first six months and the risk of ALL in children 0-15 years of SOLCA Cancer Institute between the years 2000-2010 and compared with children did not develop the disease, the HVCM.

Methodology.- The study was of 130 children (cases) SOLCA Institute, diagnosed with ALL and 390 HVCM controls, matched for age, sex, origin and familial risk factors. Data were collected from a direct survey of mothers, parents or guardians and then tabulated in EXCEL and SPSS, for the analysis used descriptive statistics (percentage frequency) to establish an association OR, CI (95%) and chi square for statistical significance and multivariate logistic regression to control variables.

Results.- In the cases, 45.38% had an exclusive breastfeeding for the first six months, versus a 65.38% that was observed in controls. The association OR was 2.27 and multivariable logistic regression showed that increased risk of ALL (5.6) in those children who breastfed less than 8 times a day.

Conclusion.- They have more risk of developing ALL children not exclusively breastfed the first 6 months compared to children who do.
