Nutrition 526 - 2012 Framing Maternal & Infant Nutrition

Healthy People 2020 Maternal, Infant and Child Health • Why do we care about maternal and infant nutritional health? • What are the determinants of maternal and infant health? • What are some key indicators of maternal and infant nutritional health: preconceptionally, in the fetus & infant, during pregnancy?

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

A Public Health Approach to Maternal and Infant Health • Assessment • Policy Development • Assurance: Surveillance and monitoring progress towards goals

Assessment • Pregnancy population characteristics • Maternal health indicators • Infant health indicators

In 2008 births and birth rate were ~ 2% less than 2007; in 2009 they were ~ 3% less than 2008. http: //www. cdc. gov/nchs/products/nvsr. htm

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.
