Exclusive breastfeeding linked to slight decrease in adolescent LDL Cholesterol (2minutemedicine.com)

[2 Minute Medicine, 4/9/19]  Exclusive breastfeeding in the first 3 months of life, as opposed to mixed breast and bottle feeding and exclusive bottle feeding, was associated with lower low-density lipoprotein (LDL) cholesterol and lower total cholesterol in adolescence.

There was no association between exclusive breastfeeding and body mass index (BMI) or total body fat percentage.

Previous studies have demonstrated a possible link between breastfeeding in infancy and improved lipid profiles later in life.

However, many of these studies have been burdened by bias, specifically related to breastfeeding as associated with higher socioeconomic class in Western culture. In this study, researchers utilized data from a Hong Kong–based cohort study originally designed to investigate the impact of second-hand smoke. Investigators analyzed breastfeeding practices at various ages in the first year of life, comparing those who exclusively breastfed to those who both breast and bottle fed and those who exclusively bottle fed. Researchers completed chart reviews and in-person assessments of weight, body fat percentage, and lipid levels. Though researchers demonstrated a statistically significant association between breastfeeding exclusively for the first 3 months of life and lower LDL and total cholesterol in adolescence, they found no association between breast versus bottle or mixed feeding and BMI or fat percentage. The study has many strengths, including garnering a broad cross-section of the population and evaluating a cultural group in which breastfeeding is not exclusive to those in more advantaged socioeconomic classes. The results, however, ultimately lack clinical significance, as the actual difference between the total LDL and cholesterol levels varied only slightly. Such minor differences are unlikely to have significant impact on long term cardiovascular health………
