To assess factors associated with the prevalence of breastfeeding in a cohort of Spanish primiparous pregnant women to whom a health education program was applied.
Prospective, descriptive, and inferential cohort analysis with data obtained from the beginning of pregnancy to the child's year. Prevalence of breastfeeding was classified into periods or categories: (1) "non-breastfeeding"; (2) "breastfeeding until 6 months"; (3) "breastfeeding up to 12 months". The sample was 288 primiparous pregnant women divided into two groups of equal size using as a matching strategy whether they attended the health education sessions with or without an informal caregiver (mother, partner, sister): group A (primiparous women who attended the sessions without an informal caregiver; n = 144) and group B (primiparous women who attended the sessions with an informal caregiver; n = 144).
The best-associated variables with the prevalence of breastfeeding were age, vitamin B variation (postintervention-preintervention), and informal caregiver intervention. This association was statistically significant for breastfeeding up to 12 months of age compared to non-breastfeeding (age ( = 0.007); vitamin B variation ( = 0.010); caregiver intervention ( = 0.008)). The younger the breastfeeding woman, the greater the probability of breastfeeding up to 12 months (β: -0.246 (0.91); OR: 0.782 (0.654-0.935)). The greater the increase in vitamin B after the educational intervention program, the greater the probability of breastfeeding up to 12 months (β: 0.007 (0.003); OR: 1.007 (1.002-1.012)). The absence of an informal caregiver decreased the likelihood that breastfeeding would be maintained until the child's 12 months (β: -0.734 (1.024); OR: 0.065 (0.009-0.483)).
The prevalence of breastfeeding up to 12 months, in a cohort of Spanish primiparous women, increased the higher increase in vitamin B levels after applying an educational intervention program to promote breastfeeding. The prevalence of breastfeeding up to 12 months also increased with the presence of the informal caregiver and in young women.
评估在接受了健康教育项目的西班牙初产妇队列中，与母乳喂养率相关的因素。
进行前瞻性、描述性和推断性队列分析，数据收集从怀孕开始至孩子满周岁。母乳喂养率分为不同时期或类别：（1）“非母乳喂养”；（2）“母乳喂养至6个月”；（3）“母乳喂养至12个月”。样本为288名初产妇，根据是否有非正式照料者（母亲、伴侣、姐妹）陪同参加健康教育课程，将她们分为两组，每组人数相等：A组（无非正式照料者陪同参加课程的初产妇；n = 144）和B组（有非正式照料者陪同参加课程的初产妇；n = 144）。
与母乳喂养率关联最密切的变量是年龄、维生素B变化（干预后 - 干预前）和非正式照料者干预。与非母乳喂养相比，这种关联在母乳喂养至12个月时具有统计学意义（年龄（ = 0.007）；维生素B变化（ = 0.010）；照料者干预（ = 0.008））。母乳喂养的女性年龄越小，母乳喂养至12个月的可能性越大（β： - 0.246（0.91）；OR：0.782（0.654 - 0.935））。教育干预项目后维生素B增加得越多，母乳喂养至12个月的可能性越大（β：0.007（0.003）；OR：1.007（1.002 - 1.012））。没有非正式照料者会降低母乳喂养维持至孩子12个月的可能性（β： - 0.734（1.024）；OR：0.065（0.009 - 0.483））。
在西班牙初产妇队列中，应用促进母乳喂养的教育干预项目后，维生素B水平升高幅度越大，母乳喂养至12个月的比例越高。有非正式照料者以及年轻女性中，母乳喂养至12个月的比例也更高。
