  Medical Thinking

Obesity is defined by Body Mass Index (BMI) and attributed to a mismatch of energy intake (food) and energy expenditure (activity).  Treatment is focused on decreasing amount and changing character of food (low fat, low carb, etc), increasing exercise, weight loss drugs or bariatric surgery  (US Preventive Services Task Force).

  Systems Biology

Obesity is a complex neuro-endocrine-inflammatory “brain disease,” in part due to imbalance of signaling molecules leptin & ghrelin and changes in gut microbiome, and can result in pro-inflammatory state.  Highly influenced by sleep disruption and sleep deprivation.  Patterns of food intake and exercise are also significantly affected by complex neurologic factors, not just a person’s conscious choices.

Trauma-Health Equity-
Neurobiology lens

Occurrence and severity of Obesity strongly correlate with severity of childhood adverse experiences, particularly poverty, childhood sexual abuse, and the experience of everyday discrimination.

Tracked 10,774 adolescents through age 34.  New cases of severe obesity (BMI >40) of individuals not obese during adolescence found that females reporting sexual and physical abuse had an odds ratio of 2.5 increased risk of severe obesity, males had an odds ratio of 3.6, compared to individuals with no history of abuse.

Early childhood poverty leads to accelerated weight gain.  Children who spent all their childhood in poverty had a cumulative risk of twice the rate of obesity by age 9 (as compared to children no childhood poverty) – a risk which persisted into early adulthood.
