Nutrition Framing Maternal & Infant Nutrition

A Life Course Framework: T 2 – E 2 Timeline: today’s exposures influence tomorrow’s health Timing: health trajectories are particularly affected during critical periods Environment: the broader community environment strongly affects the capacity to be healthy Equity: inequality in health reflects more than genetics and personal choice

Resources & Biology Adaptive Mechanisms Goals of Reproduction DNA & metabolic programming Access to Food Knowledge & Skills Support: basic needs, health care, cultural/social Physiologic responses to reproduction & growth Behavioral responses Healthy mother who can nourish infant & produce further offspring Optimal growth & development of offspring

In 2008 births and birth rate were ~ 2% less than 2007; in 2009 they were ~ 3% less than

Population Indicators of Infant Health Infant mortality Birthweight Gestational age

Infant Mortality Infant mortality rate – Deaths of infants aged under 1 year per 1,000 or 100,000 live births. The infant mortality rate is the sum of the neonatal and postneonatal mortality rates. Neonatal mortality rate – Deaths of infants aged 0-27 days per 1,000 live births. The neonatal mortality rate is the sum of the early neonatal and late neonatal mortality rates Postneonatal mortality rate – Deaths to infants aged 28 days-1 year per 1,000 live births.

International Journal of Health Services, Volume 32, Number 4, Pages 629–656, 2002 “In summary, the rates of low birth weight and infant deaths from all causes were lower in those countries with more voter turnout, more left votes, more left members of parliament, more years of social democratic government, more women in government, a stronger social pact and various aspects of the welfare state, and low income inequality, as measured in a variety of ways.”

History Child welfare movements became noticeable in industrialized countries (U.S. and Western Europe –“Political, economic, and humanitarian motivations all converged to reduce the large wastage of child life”

History World War 1 and 2 –Recruits unfit for service –“weaklings”

History Child welfare movements directed toward general hygiene for disease prevention, dietary improvements, and antepartum care –Infant Stations: to provide clean milk, instruct new mothers on child/infant care, encourage breastfeed –Innovative approach in 1908 establishment of Division of Child Hygiene in NYC

Child Hygiene Bureau NYC Tracked from register of live births Home nursing visits Education on infant care Milk stations –“there were 1200 fewer deaths when comparable to previous summer”

Policy Development: Poor Pregnancy Outcomes are Costly Medicaid finances 40% of annual births in the US and pays for 50% of hospital stays for premature and LBW. –Medicaid-funded deliveries represented 45.6% of births in WA in The care cost for children with one of 17 common birth defects is $8 billion per year in the US.
