Breastfeeding practices in Mexico: Results from the National Demographic Dynamic Survey 2006–2018

Although actions have been taken to improve breastfeeding in Mexico, trends over the last decade and their associated factors have not been analysed. We estimated trends in breastfeeding practices at the national, rural/urban, and regional level indigenous ethnicity and socio-economic level, and their associated factors using the National Demographic Dynamics Survey (2006, 2009, 2014 and 2018). We assessed breastfeeding indicators of women with children <24 months according to The World Health Organization recommendations. Logistic regressions models of pooled data were used to estimate trends and associations with biological and sociodemographic characteristics. Between 2006 and 2018, the prevalence of ever breastfed increased from 91.8% to 94.2% (p < 0.001), whereas early initiation of breastfeeding increased from 40.8% to 59.7% (p < 0.001), with similar increments by urban/rural level. Between 2009 and 2018, the prevalence of exclusive breastfeeding in children <6 months increased from 13.0% to 20.7% (p < 0.001). The largest increase was seen in Mexico City, in nonindigenous women and those with a high socio-economic status, whereas indigenous women and those from the South had the lowest or no improvements. Breastfeeding education during pregnancy odds ratio (OR) 1.3; 95% confidence interval (CI) 1.1-1.5 was positively associated with exclusive breastfeeding, whereas being employed (OR 0.8; 95% CI 0.6-0.9) was negatively associated. Breastfeeding practices improved but are still far from recommendations. Implementing strategies like breastfeeding counselling and programmes and policies that promote and support breastfeeding for poor, indigenous, single and working mothers should be a priority for the government to ensure that all children have the best start in life.
