Health Care Costs Associated to Type of Feeding in the First Year of Life.

BACKGROUND: Breastfeeding is associated with lower risk of infectious diseases, leading to fewer hospital admissions and pediatrician consultations. It is cost saving for the health care system, however, it is not usually estimated from actual cohorts but via simulation studies. METHODS: A cohort of 970 children was followed-up for twelve months. Data on mother characteristics, pregnancy, delivery and neonate characteristics were obtained from medical records. The type of neonate feeding at discharge, 2, 4, 6, 9 and 12 months of life was reported by the mothers. Infectious diseases diagnosed in the first year of life, hospital admissions, primary care and emergency room consultations and drug treatments were obtained from neonate medical records. Health care costs were attributed using public prices and All Patients Refined-Diagnosis Related Groups (APR-DRG) classification. RESULTS: Health care costs in the first year of life were higher in children artificially fed than in those breastfed (1339.5€, 95% confidence interval (CI): 903.0-1775.0 for artificially fed vs. 443.5€, 95% CI: 193.7-694.0 for breastfed). The breakdown of costs also shows differences in primary care consultations (295.7€ for formula fed children vs. 197.9€ for breastfed children), emergency room consultations (260.1€ for artificially fed children vs. 196.2€ for breastfed children) and hospital admissions (791.6€ for artificially fed children vs. 86.9€ for breastfed children). CONCLUSIONS: Children artificially fed brought about more health care costs related to infectious diseases than those exclusively breastfed or mixed breastfed. Excess costs were caused in hospital admissions, primary care consultations, emergency room consultations and drug consumption.

Factors associated with duration of breastfeeding in Spain: a cohort study.

BACKGROUND: Factors associated with duration of breastfeeding have been usually studied at specific times after birth. Little is known about how much time is added to breastfeeding by each associated factor. METHODS: A cohort of 969 mother-child dyads was followed-up for twelve months at the Marqués de Valdecilla University Hospital, Spain, in 2018. Data on mother characteristics, pregnancy, delivery and children characteristics were obtained from medical records. Length of breastfeeding was reported by the mothers and recorded in paediatric medical record at hospital discharge and 2, 4, 6, 9 and 12 months of life. Factors associated with duration of breastfeeding were analysed via multivariate Weibull regression parameterized as accelerated time of failure. Results are presented as time ratios. RESULTS: About four out of five children were breastfed at hospital discharge, although this proportion dropped to 65% in children born from smoker women, 70% in preterm children and 68% in neonates weighting less than 2500 g. Mother's age was associated with longer breastfeeding, adding 2% more breastfeeding time per year (adjusted time ratio 1.02; 95% confidence interval 1.00, 1.04). Children born from mothers with university studies were breastfed 53% more time than those born from mothers with primary studies (adjusted time ratio 1.53; 95% confidence interval 1.21, 1.95); smoking in pregnancy decreased length of breastfeeding by 41% (adjusted time ratio 0.59; 95% confidence interval 0.46, 0.76). Other factors associated with longer breastfeeding were single pregnancy and newborn weight over 2500 g. CONCLUSIONS: Analysing factors associated with duration of breastfeeding as time parameters allows us to quantify the amount of time gained or lost by each factor, which could make it easier to evaluate the relevance of programmes directed to promote facilitating breastfeeding factors.

Impact of Maternal Smoking on the Onset of Breastfeeding versus Formula Feeding: A Cross-Sectional Study.

This study sought to estimate the prevalence of maternal smoking and its association with exclusive breastfeeding vs. formula feeding. A cross-sectional study was performed on postpartum women at a public hospital in Spain, between January and August 2018. The main variables studied were their age, level of study, smoking habits, and chosen mode of infant feeding. In total, 948 postpartum women were included. Of these, 12.45% were smokers who smoked a mean of 7.23 cigarettes/day. Among the group of smokers, the probability of feeding the newborns with formula milk was multiplied by 2.32 ([95%CI 1.50-3.58] p < 0.001). When stratifying tobacco use into mild, moderate and severe, we found a statistically significant dose-response pattern. These associations and their statistical significance were maintained when adjusting by age and level of study. In conclusion, in the group of postpartum mothers who smoked, the probability of feeding the newborns with formula milk doubled. Our data highlight the need to improve health education programs in women of childbearing age, especially during pregnancy.
