A research team from Boston Children’s Hospital have recently published a paper on a link between childhood adversity and increased body mass index (BMI) in adolescence.
The project looked at 147 teenagers, 60 of whom had experienced some kind of adversity in childhood.
The results were interesting: a history of sexual or emotional abuse, or of bullying by other children, did not correlate with any increase or decrease in BMI. However, those who had experienced physical abuse or who had seen domestic violence happen in the home had higher BMIs than their peers.
In participants who were witnesses of domestic violence, the likelihood of being overweight as an adolescent was almost six times the average, even after adjusting for potential confounders. There were no significant gender differences – the correlations seemed to be equally prevalent in all genders.
