Predictors for early introduction of solid food among Danish mothers and infants: an observational study

Background Early introduction of complementary feeding may interfere with breastfeeding and the infant’s self-controlled appetite resulting in increased growth. The aim of the present study was to investigate predictors for early introduction of solid food. Methods In an observational study Danish mothers filled in a self-administered questionnaire approximately six months after birth. The questionnaire included questions about factors related to the infant, the mother, attachment and feeding known to influence time for introduction of solid food. The study population consisted of 4503 infants. Data were analysed using ordered logistic regression models. Outcome variable was time for introduction to solid food. Results Almost all of the included infants 4386 (97%) initiated breastfeeding. At weeks 16, 17–25, 25+, 330 infants (7%); 2923 (65%); and 1250 (28%), respectively had been introduced to solid food. Full breastfeeding at five weeks was the most influential predictor for later introduction of solid food (OR = 2.52 CI: 1.93-3.28). Among infant factors male gender, increased gestational age at birth, and higher birth weight were found to be statistically significant predictors. Among maternal factors, lower maternal age, higher BMI, and being primipara were significant predictors, and among attachment factors mother’s reported perception of the infant as being temperamental, and not recognising early infant cues of hunger were significant predictors for earlier introduction of solid food. Supplementary analyses of interactions between the predictors showed that the association of maternal perceived infant temperament on early introduction was restricted to primiparae, that the mother’s pre-pregnancy BMI had no impact if the infant was fully breastfed at week five, and that birth weight was only associated if the mother had reported early uncertainty in recognising infant’s cues of hunger. Conclusions Breastfeeding was the single most powerful indicator for preventing early introduction to solid food. Modifiable predictors pointed to the importance of supporting breastfeeding and educating primipara and mothers with low birth weight infants to be able to read and respond to their infants’ cues to prevent early introduction to solid food

The role of intention and self-efficacy on the association between breastfeeding of first and second child, a Danish cohort study

Abstract Background The impact of parity on breastfeeding duration may be explained by physiological as well as psychosocial factors. The aim in the present study was to investigate the mediating influence of intention and self-efficacy on the association between the breastfeeding duration of the first and the following child. Methods A 5-year Danish cohort study with data from online questionnaires was used. Data came from 1162 women, who participated in the “Ready for child” trial in 2006–7 and gave birth to their second child within 5 years in 2011–3. Analysis included multiple regression models with exclusive/any breastfeeding duration of first child as the exposure variables, intention and self-efficacy measured as mediators, and exclusive/any breastfeeding duration of the second child as the outcome variables. Results Duration of exclusive breastfeeding of the first child was significantly associated with exclusive breastfeeding duration of the second child (p <  0.001) and with the self-reported intention and self-efficacy in the ability to breastfeed the second child (p <  0.001). The exclusive breastfeeding period was slightly longer for the second child. Self-efficacy and intention mediated the association between breastfeeding duration in the first and second child. Together the two factors explained 48% of the association in exclusive breastfeeding and 27% of the association in any breastfeeding between the first and second child. Conclusion Due to a reinforcing effect of intention and self-efficacy, breastfeeding support should focus on helping the first time mothers to succeed as well as to identify the second time mother with low self-efficacy and additional need for support

Nipple shield use in preterm infants: Prevalence, motives for use and association with exclusive breastfeeding-Results from a national cohort study.

Background and aimPrevalence and motives for nipple shield use are not well studied in preterm infants and recommendations of nipple shield use in preterm infants are inconsistent. The aim of this study was to determine the prevalence of nipple shield use, explore the motives for nipple shield use and elucidate the association with exclusive breastfeeding in preterm infants.MethodsThe study was part of a prospective survey of a Danish national cohort of preterm infants based on questionnaires answered by the 1221 mothers of 1488 preterm infants with gestational age of 24-36 weeks. Data on nipple shield use was available for 1407 infants.ResultsNipple shields were used by 54% of the mother-infant dyads for many different motives and was more often related to breastfeeding problems associated with the infant than with the mother. The most common motive for nipple shield use was "infant slipped the nipple" (52%). The lower the gestational age, the more frequently nipple shields were used for motives related to the infant. For those using a nipple shield, only the motive "infant fell asleep at the breast" was associated with a higher risk of not breastfeeding exclusively at discharge (OR 1.90 (95% CI 1.15; 3.13), p = 0.012), and "breast too engorged" with a lower risk of not breastfeeding exclusively (OR 0.32 (0.16; 0.63), p = 0.001), but overall nipple shield use was associated with failure of exclusive breastfeeding.ConclusionThe present study does not give justifiable motives for nipple shield use, except for "breast too engorged". Nipple shields should not be recommended for infants falling asleep at the breast, instead, staff and mothers should be patient, allowing the dyad time skin-to-skin. The results indicate that the use of a nipple shield does not promote exclusive breastfeeding in preterm infants
