Life Course Approach to Health
-The health status of any individual at any point in time is affected by one’s physical and social
environment at their earlier stages of life — starting in utero
-Health operates through cumulative, pathway, and latency effects
Dutch Famine Birth Cohort Study
-Children were born smaller than expected
-The children’s children (second generation) were also born smaller than average
-Children exposed to famine in utero were more susceptible to diabetes, obesity,
cardiovascular disease, kidney problems, other health problems (incld. mental health)
The Barker Hypothesis
-Formulated by Dr. David Barket, M.D., Ph.D, FRS
-Physician and professor of clinical epidemiology at the University of Southampton, UK &
Professor in the Department of Cardiovascular Medicine at the Oregon Health and Science
The Barker Hypothesis (1994): “Poor nutrition, health and development among girls and young
women is the origin of high death rates from cardiovascular disease in the next generation.”
-Heart disease is linked to low birth weight
-Low birth weight results from the mother’s lifetime nutrition, not what the mother has eaten
each day in pregnancy
Q: Why is there a higher risk of coronary heart disease in people with low birth weight?
Placenta: The mother’s nutrition shapes the placenta, and the placenta shapes the baby’s heart
