The association between arsenic concentrations in breast milk and child growth and risk of overweight in children: An analysis of a Norwegian birth cohort

Over the last decades, there has been an increase in the prevalence of overweight and obesity among children, representing a serious public health burden (WHO, 2017). Weight gain is largely due to an imbalance between energy intake and expenditure, however, environmental factors have also been proposed. A large meta-analysis from 15 countries reported that, contrary to expectations, maternal fish intake was associated with increased risk of rapid growth in infancy and childhood obesity, and suggested that obesogenic chemical pollutants in fish explained this association (Stratakis et al., 2016). Arsenic is a priority chemical of major public health concern (WHO, 2017;
ATSDR, 2015). The Norwegian Institute of Public Health conducted the Norwegian Human Milk Study (HUMIS) from 2002–2009, with the aim of investigating persistent organic pollutants in breast milk and possible health effects in children. The study provides interesting data for the analysis of arsenic in breast milk and children’s development. My research question is:
Is there an association between different types of arsenic concentrations in breast milk and
1) Infant growth during the first 2 years
2) Child BMI at 7 year old
