To assess the adherence to three methods of food introduction for 7-month-old babies.
This is a randomized clinical trial conducted with mother-infant pairs, submitted to the intervention with five and a half months of age and three different methods for food introduction according to randomization: Parent-Led Weaning (PLW), Baby-Led Introduction to SolidS (BLISS), or mixed (specially developed for this study). Adherence to the method was assessed at the seventh month of age, via telephone call to the caregiver by a researcher blinded to the method. The analyses were performed using the Chi-Square test and data are presented in absolute numbers and percentages.
A total of 139 mother-infant pairs were evaluated; 46 of them were allocated to the PLW method; 47, to the BLISS; and 46, to the mixed. At seven months of age, 60 (43.2%) mothers reported that the infants were following the proposed feeding method. When analyzing each approach, the mixed method showed a higher likelihood of adherence (71.7%, n=33), followed by the PLW method (39.1%, n=18) and by the BLISS (19.2%, n=9) (p<0.001). Among the sample that did not follow the proposed method, those that had been randomized to the PLW and BLISS methods mostly migrated to the mixed method (92.9%; n=26 and 92.1%; n=35, respectively) (p<0.001).
Complementary feeding in a mixed approach obtained greater adherence in 7-month-old babies.
评估 7 月龄婴儿三种食物引入方法的依从性。
这是一项随机临床试验，纳入母婴对，在 5 个半月龄时接受干预，并根据随机分组接受三种不同的食物引入方法：家长主导的辅食添加（PLW）、婴儿主导的固体食物引入（BLISS）或混合（专为本研究开发）。在 7 月龄时，通过研究者对方法不知情的电话询问照顾者来评估方法的依从性。分析采用卡方检验，数据以绝对数和百分比表示。
共评估了 139 对母婴，其中 46 对分配到 PLW 方法，47 对分配到 BLISS 方法，46 对分配到混合方法。7 月龄时，有 60 名（43.2%）母亲报告婴儿遵循了建议的喂养方法。分析每种方法时，混合方法的依从性更高（71.7%，n=33），其次是 PLW 方法（39.1%，n=18）和 BLISS 方法（19.2%，n=9）（p<0.001）。在未遵循建议方法的样本中，那些被随机分配到 PLW 和 BLISS 方法的婴儿大多转向混合方法（92.9%，n=26 和 92.1%，n=35）（p<0.001）。
混合方法的补充喂养在 7 月龄婴儿中获得了更高的依从性。
