Diferencias entre conductas alimentarias de preescolares que recibieron lactancia materna completa y preescolares que recibieron sucedáneos de la leche humana / Eating behaviors of preschoolers who were exclusively breastfed, and preschoolers who received human milk substitutes

El propósito fue demostrar diferencias en las conductas alimentarias entre preescolares que recibieron lactancia materna completa (LMC: exclusiva o predominante) y preescolares que recibieron sucedáneos de la leche humana (SLH), que acuden a jardín de niños de la zona metropolitana de Guadalajara. En estudio trasversal analítico por conveniencia, se seleccionaron a 177 preescolares de tres a cinco años de edad, sanos, nacidos a término, peso normal al nacer, con antecedentes de alimentación con LME o SLH que acudían a tres jardines de niños. Se aplicó un cuestionario validado de conductas alimentarias que consta de ocho escalas. Se obtuvieron variables socioeconómicas y demográficas de las familias e indicadores antropométricos de los participantes. Se aplicaron pruebas t de Student, U de Mann-Whitney, Chi cuadrado, razón de momios, coeficiente de correlación de Pearson y regresión logística. Hubo 2.8 veces mayor probabilidad de puntaje elevado en la escala comer menos por emociones en el grupo de SLH [RM=2.8 (1.0, 8.3), p=0.037]. Se observaron 15 correlaciones significativas entre las diferentes escalas del cuestionario en el grupo de LMC (62.5%) y nueve en el grupo de SLH (37.5%). Hubo siete correlaciones significativas entre las escalas en el grupo LMC que no fueron significativas en el grupo de SLH. En preescolares que recibieron LMC, a mayor lentitud para comer hubo menor irritabilidad hacia los alimentos (r=-0.325, p=0.01). Los preescolares con antecedentes de LMC tendrían menor probabilidad de alteraciones de conducta alimentaria y mostraron mayor número de correlaciones significativas entre las escalas que los preescolares que recibieron SLH(AU)

The purpose was to demonstrate differences in eating behaviors among preschool children who received full breastfeeding (FBF: exclusive or predominant) and preschool children who received human milk substitutes (HMS), who attend kindergarten in the metropolitan area of Guadalajara, Mexico. In analytical cross-sectional study by convenience, 177 preschoolers, three to five years old, healthy, term infants with normal weight at birth and feeding history of FBF or HMS attending three kindergartens were selected. A validated questionnaire of eating behaviors consisting of eight scales was applied. Socioeconomic and demographic variables of families and anthropometric indicators of participants were obtained. Student's t test, U Mann-Whitney, chi-square, odds ratio, Pearson correlation coefficient and logistic regression tests were applied. There were 2.8 times more likely to score high on the scale eat less by emotions in HMS group [OR = 2.8 (1.0, 8.3), p = 0.037]. Fifteen significant correlations between different scales of the questionnaire in the FBF group (62.5%) and nine in the HMS group (37.5%) were observed. There were seven significant correlations among the scales in FBF group, but not significant in the HMS group. In preschoolers receiving FBF, more frequency of eating slowly was related to less irritability to food (r=-0.325, p=0.01).Preschoolers with a history of FBF would be less likely to have alterations in eating behavior and showed more significant correlations between the scales that preschoolers who received HMS(AU)

Food taboos among nursing mothers of Mexico.

This cross-sectional study was carried out in Guadalajara, Mexico, during 1998-1999 to identify food taboos among nursing mothers who participated in a breast-feeding support programme. The study included 493 nursing mothers who were interviewed 10-45 days after delivery. A chi-square test was used for finding an association among food taboos, mother's characteristics, and demographic variables. 50.3% of the mothers avoided at least one food in their diet after childbirth due to beliefs that it was harmful during breast-feeding. Forty-seven percent avoided three or more foods. Fruits and vegetables (62%) and legumes (20%) were the most-avoided foods. These food taboos were associated with living more than 10 years in Guadalajara city (odds ratio [OR] 1.95 [1.25-3.09], p = 0.002), breast-feeding experience (OR 1.91 [1.18-3.12], p = 0.005), no-prenatal information about breast-feeding (OR 1.59 [1.08-2.34], (p = 0.01), and other people's suggestion to complement breast-feeding (OR 1.61 [1.09-2.38], p = 0.01). A supportive approach and efficient communication, taking into account mother's characteristics, might reduce the gap between scientific recommendations and nutritional practices of mothers willing to nurse their infants.
