the leading cause of infant death in the us is
Infant mortality Causes of infant mortality directly lead to the death.[13] Environmental and social barriers prevent access to basic medical resources and thus contribute to an increasing infant mortality rate; 99% of infant deaths occur in developing countries, and 86% of these deaths are due to infections, premature births, complications during delivery, and perinatal asphyxia and birth injuries.[10] Greatest percentage reduction of infant mortality occurs in countries that already have low rates of infant mortality.[14] Common causes are preventable with low-cost measures. In the United States, a primary determinant of infant mortality risk is infant birth weight with lower birth weights increasing the risk of infant mortality. The determinants of low birth weight include socio-economic, psychological, behavioral and environmental factors.[15]
