Factors associated with breastfeeding maintenance for 12 months or more: a systematic review

The prevalence of exclusive breastfeeding and its associated factors in Cape Verde

Background

Exclusive breastfeeding (EBF) for the first 6 months of life is essential for maternal and child health. Breast milk is considered the most suitable food for the child in early years of life. Studies carried out in Cape Verde (INE; MSSS, Apresentação dos Principais Resultados Preliminares do IDSR-III, 2018) showed prevalence of EBF below the values recommended by the (WHO & UNICEF, Global Breastfeeding Scorecard, 2018. Enabling Women To Breastfeed Through Better Policies And Programmes, 2019). However, the determinants of EBF across the country have never been identified. The objective of this study is to estimate prevalence and identify the determinants of EBF in Cape Verde.

Methods

This is a quantitative, descriptive and cross-sectional study carried out between July 2018 and March 2019. The study population consisted of 1717 mothers of children aged less than or equal to 2 years, users of the Health Centers of the islands of Santo Antão, S. Vicente, Sal, Santiago and Fogo. A structured questionnaire was applied to mothers through an interview.

The prevalence of exclusive breastfeeding was estimated by frequency analysis. The chi-square test was used to assess the association between the duration of EB and the variables maternity leave, mother’s education, family income and health care variables. In order to identify the determinants of EBF, a binary logistic regression analysis was used.

Results

At the time of data collection, 32.50% of mothers practiced EBF. The present study shows that exclusive breastfeeding is influenced by several factors. The most representatives are maternal age (OR = 0.001*), level of education (OR = 0.028*), parity (OR = 0.004*) and number of prenatal consultations (OR = 0.019*). Receiving breastfeeding counseling was the only health care variable that was associated with the duration of EBF (p = 0.029).

Conclusion

In Cape Verde, the prevalence of EBF can be considered reasonable. The present study shows that EBF in the country is influenced by maternal age, level of education, parity and number of prenatal consultations.

Risk factors for and protective factors against breastfeeding interruption before 2 years: a birth cohort study

BACKGROUND

Little is known about the factors associated with the World Health Organization (WHO) recommendation of breastfeeding for at least 2 years. The objective of this study was to identify risk factors for and protective factors against breastfeeding interruption before 2 years of age.

METHODS

In this live birth cohort, mother and infant dyads were followed for 2 years. Data collection was performed at the maternity ward and subsequently at the children's homes, monthly during the first 6 months of life and then at 9, 12, 18, and 24 months. The outcome of interest was breastfeeding interruption before 2 years of age. Median duration of breastfeeding was estimated using Kaplan-Meier's survival analysis, and the associations were tested using Cox's hierarchical multivariate model. Significance was set at 5%.

RESULTS

Data from a total of 1344 dyads were assessed. Median breastfeeding duration was 385 days. The following risk factors for breastfeeding interruption were identified: white skin color (adjusted hazard ratio [HRa]: 1.31; 95% confidence interval [95%CI]: 1.10-1.56), primiparity (HRa: 1.21; 95%CI: 1.05-1.40), working outside the home (HRa: 1.52; 95%CI: 1.30-1.77), child sex male (HRa: 1.18; 95%CI: 1.03-1.35) and use of a pacifier (HRa: 3.46; 95%CI: 2.98-4.01). Conversely, the following protective factors were identified: lower family income (HRa: 0.81; 95%CI: 0.71-0.94), mother-infant bed-sharing (HRa:0.61, 95%CI: 0.52-0.73), on-demand breastfeeding in the first month (HRa: 0.64; 95%CI: 0.47-0.89) and exclusive breastfeeding at 4 months (HRa: 0.58, 95%CI: 0.48-0.70).

CONCLUSIONS

The findings allowed to identify both risk factors for and protective factors against breastfeeding interruption before 2 years of age. Knowledge of these factors may help prevent this event and aid in the development of programs that help women maintain breastfeeding for at least 2 years, as recommended by the WHO.

Determinants of Full Breastfeeding at 6 Months and Any Breastfeeding at 12 and 24 Months among Women in Sydney: Findings from the HSHK Birth Cohort Study

The aim of this study was to report on breastfeeding duration up to 24 months and determine the predictors of breastfeeding duration among women in South Western Sydney, one of the most culturally diverse and socioeconomically disadvantaged regions of New South Wales (NSW), Australia. Mother–infant dyads (n = 1035) were recruited to the Healthy Smiles Healthy Kids birth cohort study. Study data were collected through telephone interviews at 2, 4, 8, 12, and 24 months postpartum. Cox proportional hazards models were used to determine factors associated with the risk of stopping full breastfeeding at six months and any breastfeeding at 12 and 24 months. The majority of mothers (92.3%) had initiated breastfeeding. At six months, 13.5% of infants were fully breastfed, while 49.9% received some breast milk. Only 25.5% and 2.9% of infants received some breast milk at 12 and 24 months, respectively. Lower maternal education level, lower socioeconomic status, full-time employment, maternal smoking during pregnancy, and caesarean delivery were associated with increased risk of stopping full breastfeeding at six months and any breastfeeding at 12 and 24 months. Older maternal age and partner’s preference for breastfeeding were associated with an increased likelihood of continuing any breastfeeding at 12 and 24 months. These findings present a number of opportunities for prolonging breastfeeding duration in disadvantaged communities in NSW.
