Studies on prevalence and effects of breastfeeding call for reliable and precise data collection to optimize infant nutrition, growth, and health. Data on breastfeeding and infant nutrition are at risk of, for example, recall bias or social desirability bias.
The aim of the present analysis was to compare data on infant nutrition, that is, breastfeeding, use of infant formula, and introduction to complementary foods, obtained by four different methods. We assumed that weekly short message service (SMS) questions were the most reliable method, to which the other methods were compared.
The study population was part of the Odense Child Cohort. The four methods used were: (a) self-administered questionnaire 3 months postpartum, (b) self-administered questionnaire 18 months postpartum, (c) registrations from health visitors visiting the families several times within the first year of life, and (d) weekly SMS questions introduced shortly after birth.
In total, 639 singleton mothers with data from all four methods were included. The proportion of mothers initiating breastfeeding varied from 86% to 97%, the mean duration of exclusive breastfeeding from 12 to 19 weeks, and the mean age when introduced to complementary foods from 19 to 21 weeks. The mean duration of any breastfeeding was 33 weeks across methods.
Compared with the weekly SMS questions, the self-administered questionnaires and the health visitors' reports resulted in a greater proportion of mothers with an unknown breastfeeding status, a longer duration of exclusive breastfeeding and later introduction to complementary foods, while the duration of any breastfeeding did not differ.
关于母乳喂养的患病率和影响的研究需要可靠且精确的数据收集，以优化婴儿营养、生长和健康。母乳喂养和婴儿营养数据存在例如回忆偏倚或社会期望偏倚等风险。
本分析的目的是比较通过四种不同方法获得的婴儿营养数据，即母乳喂养、婴儿配方奶粉使用情况和辅食添加情况。我们假设每周短信询问是最可靠的方法，并将其他方法与之进行比较。
研究人群是欧登塞儿童队列的一部分。使用的四种方法分别是：(a)产后3个月的自填问卷；(b)产后18个月的自填问卷；(c)健康访视员在婴儿出生后第一年内多次家访的记录；(d)出生后不久引入的每周短信询问。
总共纳入了639名单胎母亲，她们有来自所有四种方法的数据。开始母乳喂养的母亲比例在86%至97%之间，纯母乳喂养的平均持续时间在12至19周之间，开始添加辅食的平均年龄在19至21周之间。各种方法下任何形式母乳喂养的平均持续时间为33周。
与每周短信询问相比，自填问卷和健康访视员报告导致未知母乳喂养状况的母亲比例更高，纯母乳喂养持续时间更长且辅食添加更晚，而任何形式母乳喂养的持续时间没有差异。
