Effective strategies are needed to promote it. The aim of this study was to evaluate the effectiveness of printed infographics designed to promote breastfeeding in mothers from Sonora.  Methods: We prospectively studied lactation regimes from birth. Intention to breastfeed, general characteristics of the mother-infant dyad, and telephone number were registered. Participants received educational training in the hospital; those assigned to the intervention group (IG) also received up to five infographic materials (designed and evaluated previously) in different perinatal periods, while those in the control group (CG) did not. At two months postpartum, the infant feeding practice and reasons for introducing formula were collected by phone. Data were analyzed with the &#967;2 test.  Results: Of 1705 women enrolled, 57% were missed during follow-up. Although 99% of participants planned to breastfeed, 92% of IG did so, compared to 78% of CG (95% Confidence interval [CI]: 7.04, 19.98; p &lt; 0.0001). Mothers in the IG used more formula than those in the CG (6 vs. 21%; 95% CI: &#8722;20.54, &#8722;8.0; p &lt; 0.0001), arguing insufficient milk production. The delivery of three infographics (one in prepartum and two in the hospital-training), or five infographics in different periods, promoted breastfeeding in 95% of participants.  Conclusions: The distribution of printed infographics and initial training promoted breastfeeding, although not its exclusivity.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen  Introducción: En México es baja la prevalencia del amamantamiento exclusivo durante 6 meses (28.6%); en el estado de Sonora, solo es del 15%. Se requieren estrategias efectivas para su promoción. El objetivo de este estudio fue evaluar la efectividad de la infografía impresa diseñada para promover el amamantamiento en madres sonorenses.  Método: Estudiamos prospectivamente la lactancia desde el nacimiento. Se registraron la intención de amamantar, las características generales de la díada madre-hijo y el número telefónico. Las participantes tuvieron capacitación educativa en el hospital; las asignadas al grupo intervenido (GI) recibieron además hasta cinco materiales infográficos (diseñados y evaluados en un estudio previo) en diferentes periodos perinatales, mientras que las del grupo control (GC) no los recibieron. A los dos meses posparto se consultó telefónicamente el tipo de alimentación infantil y los motivos para introducir la fórmula. Los datos se analizaron con la prueba de &#967;2.  Resultados: De las 1705 mujeres reclutadas, se perdieron el 57% en el seguimiento. Aunque el 99% del total de las participantes planeó amamantar, el 92% del GI lo hacía a los dos meses posparto, en comparación con el 78% del GC (intervalo de confianza del 95% [IC95%]: 7.04 a 19.98; p &lt; 0.0001). Las madres del GI usaron menos lactancia con fórmula que las del GC (6% vs. 21%; IC95%: &#8722;20.54 a &#8722;8.0; p &lt; 0.0001), argumentando insuficiencia láctea. La entrega de tres infografías (una en preparto y dos en capacitación), al igual que cinco infografías en diferentes periodos, promovió el amamantamiento en el 95% de las participantes.  Conclusiones: La distribución de infografía impresa, además de la capacitación inicial, promovió el amamantamiento, aunque no su exclusividad.]]></p></abstract>
