    • 20% environment (pollution, etc.)
    • 51% lifestyle factors (besides not smoking, a healthy diet & ample exercise contribute most to longevity)
  36. Aging: Cardiovascular
    • Less arterial elasticity, decreased blood flow, heart muscle contraction is diminished and cardiac output falls
    • Blood flow to coronary arteries is decreased - can lead to hypertension and less ability to exchange gases and increase oxygen intake
  37. Aging: Endocrine System
    • Decrease in growth hormone and IGF-1
    • -Affect muscles and muscle function
    • -Stay physically active to reduce muscle loss
    • Decrease in estrogen-menopause

  149. Obesity & Breastfeeding
    • High prevalence of childhood obesity in the US
    • ›Breastfed infants may be less likely to become overweight or obese as adults
  150. Association of Breastfeeding & Childhood Overweight 
    • Reviewed 9 studies
    • Reported BMI for children 5-18 years old
    • Each study adjusted for ≥3 confounding factors
    • Odds ratio (OR) indicated a protective effect of breastfeeding against overweight
  151. Potential Effects of Breastfeeding Duration
    • Reviewed 17 studies
    • Studies correlated incidence of childhood overweight and duration of breastfeeding from <1 month - >9 months (split into 5 categories)
    • OR indicated risk of overweight continuously decreased by breastfeeding duration

  152. Effect of Breastfeeding on Mean BMI
    • Reviewed 11 studies
    • Compared BMI of 1-70 year old breastfed subjects to those formula fed
    • After adjusting for confounding factors no effect was observed
    • Authors concluded that “breastfeeding not likely to reduce BMI”
  153. Limitations of Observational Studies
    • Publication bias
    • ›Potential heterogeneity
    • ›Residual confounding
  154. Promotion of Breastfeeding Intervention Trial
    • ›The only interventional study
    • ›Assigned women to a breastfeeding promotion and observed for 12 months
    • ›16,491 participants originally enrolled 13,389 followed-up at 6.5 years
    • ›Successful at initiating breastfeeding
    • ›Findings not statistically significant with respect to body composition
  155. Duration of Breastfeeding
    • Each additional month of breastfeeding reduced risk of becoming overweight in adulthood by 4%
    • •Up to 9 months
    • ›Breastfeeding for ≥16 weeks reduced the risk of obesity at 4 years of age
  156. Feeding Practices
    • Breastfed infants are typically leaner
    • •Ability to self regulate intake
    • -Breastfeeding allows the infant to control the amount of milk consumed
    • -FF infants consume more and gain weight more rapidly
    • 3.2 times > risk of rapid weight gain between ages 2-6 years ›
    • Breastfeeding may induce lower plasma insulin levels
    • •Decreases fat storage and prevents excessive early adipocyte development
    • •FF infants have higher plasma insulin levels,
    • stimulating fat deposition and formation of adipocytes
    • Higher protein in formula may stimulate higher insulin secretion
    • Breastfeeding has been shown to promote slower infant growth velocity
    • •FF stimulates greater postnatal growth with adiposity rebound occurring earlier
    • The higher protein content of formula maybe responsible
