Based on birth and death data for 217,798 children born in Georgia in 1989 and 1990, infants without a father’s name on their birth certificate (17.9 percent of the total) were 2.3 times more likely to die in the first year of life compared to infants with a father’s name on their birth certificate.

Unmarried mothers are less likely to obtain prenatal care and more likely to have a low birth-weight baby. Researchers find that these negative effects persist even when they take into account factors, such as parental education, that often distinguish single-parent from two-parent families.

Expectant fathers can play a powerful role as advocates of breast feeding to their wives. Three-fourths of women whose partners attended a breastfeeding promotion class initiated breastfeeding.

Fathers’ knowledge about breastfeeding increases the likelihood that a child will be breastfed. Children who fathers knew more had a 1.76 higher chance of being breastfed at the end of the first month and 1.91 higher chance of receiving maternal milk at the end of the third month.

A study of 2,921 mothers revealed that single mothers were twice as likely as married mothers to experience a bout of depression in the prior year. Single mothers also reported higher levels of stress, fewer contacts with family and friends, less involvement with church or social groups and less overall social support.

In a longitudinal study of more than 10,000 families, researchers found that toddlers living in stepfamilies and single-parent families were more likely to suffer a burn, have a bad fall, or be scarred from an accident compared to kids living with both of their biological parents.

Children who live apart from their fathers are more likely to be diagnosed with asthma and experience an asthma-related emergency even after taking into account demographic and socioeconomic conditions. Unmarried, cohabiting parents and unmarried parents living apart are 1.76 and 2.61 times, respectively, more likely to have their child diagnosed with asthma. Marital disruption after birth is associated with a 6-fold increase in the likelihood a children will require an emergency room visit and 5-fold increase of an asthma-related emergency.
