Background
- Previous studies have indicated that pre- and post-natal malnutrition can result in long term changes to the structure and functionality of the brain, impairing memory and learning in childhood and adolescence
- There has been less emphasis on researching how malnutrition in the first year of life affects intellectual capacity across the lifespan
- The “Barbados Nutrition Study” assessed IQ and academic skills in adults in Barbados who were born with a moderate birth rate, but experienced moderate to severe malnutrition in their first year of life
- Individuals were enrolled in a nutritional health intervention program and monitored until they were at least 12 years of age to ensure they were in good health
- The control group consisted of healthy individuals from the same neighborhoods and classrooms who did not experience malnourishment in their first year of life
Summary
- Malnutrition in pregnancy and childhood can cause generational health problems
- Undernutrition in pregnant mothers and children was strongly associated with…
- Shorter adult height
- Less schooling
- Reduced economic productivity
- Lower offspring birthweight in women (birthweight is positively associated with lung function, the incidence of some cancers; undernutrition could be associated with mental illness)
- Lower weight and malnutrition in childhood followed by weight gain after two years of age was found to be risk factors for high glucose concentrations, elevated blood pressure and harmful lipid profiles once adult BMI and height were adjusted for, suggesting that rapid postnatal weight gain, after infancy, is linked to these conditions
Key Quotes:
- “Poor fetal growth or stunting in the first 2 years of life leads to irreversible damage, including shorter adult height, lower attained schooling, reduced adult income, and decreased offspring birthweight.”
- “Children who are undernourished in the first 2 years of life and who put on weight rapidly later in childhood and in adolescence are at high risk of chronic diseases related to nutrition.”
- “We conclude that damage suffered in early life leads to permanent impairment, and might also affect future generations.”
