Biostatistical investigation of correlation between breastfeeding and obesity

Breastfeeding is a classic aspect of health, which has benefits for both children and mothers in the long and short terms. In Europe, the obesity epidemic for children becomes an urgent problem needed to be solved. Recent research indicates that prolonging breastfeeding time would reduce the proportion of obesity and overweight. Breastfeeding has been seen as a protective factor. In this article, we make a secondary analysis of the data from several European countries in the WHO European Childhood Obesity Surveillance Initiative (COSI) to study the correlation between breastfeeding and obesity. This survey is the fourth round. The result shows that there is a positive correlation between breastfeeding and obesity.
