Educational intervention for the main caregiver of primiparous women to promote breastfeeding and the association between prolactin and nutritional parameters

BACKGROUND: In the last two years, breastfeeding rates have experienced a notable decline worldwide. Only 46% of women breastfeed their children, the figure being much lower in primiparous women. Breastfed milk is the ideal food for babies; its benefits for the health of mothers and babies are scientifically proven. Several studies show that babies who are not breastfed have a higher risk of getting sick. This fact gives rise to an important public health problem. The aim of this paper is to describe the association between presence of the caregiver in health education and increasing rates of breastfeeding. METHODS: We conducted an observational study (cohort) in a population of primiparous pregnant women (n = 88), and their main caregivers belonging to a region of central Spain. The development, content and implementation of the intervention consisted of: 1) obtaining the blood levels of pregnant women (prolactin, folic acid, vitamin B12 and transferrin) before health education (13-26 weeks of pregnancy), 2) carry out health education with two groups: A (44 pregnant women with caregivers) and B (44 without caregivers), 3) obtain the same blood levels as in the first intervention, 15 days after delivery, and finally the evaluation of the intervention with breastfeeding rates. RESULTS: The levels of prolactin (288.57 ± 107.46 nanogrammes per millilitre (ng / ml)), folic acid (16.93 ± 4.09 ng / ml), vitamin B12 (505.05 ± 213.97 picogrammes (pg) / ml) and transferrin (296.82 ± 67.61 milligrammmes per decilitre (mg / dl)) were higher in pregnant women who attended the health education program with a caregiver than in pregnant women who attended alone: prolcoactin (103.61 ± 45.48 ng / ml), folic acid (7.16 ± 5.88 ng / ml), vitamin B12 (160.59 ± 36.92 pg / ml) and transferrin (223.86 ± 44.14 mg / dl). Of the sample size of 44 primiparous people who attended the talks with caregivers, 35 (79.54%) breastfed their babies, while the other 44 primiparous women who attended alone, only seven (15.91%) established breastfeeding successfully. CONCLUSIONS: The implications for public health research are that the presence of a caregiver in health education programs modifies levels of prolactin, folic acid, vitamin B12, and transferrin, as well as increasing breastfeeding rates.
