It is clear that being a child of a teenage mother often entails numerous risks: low birth weight, complications of the mother's pregnancy and delivery, and health problems associated with poor perinatal outcomes; greater risk of perinatal death; lower IQ and academic achievement later on, including a greater risk of repeating a grade; greater risk of socio-emotional problems; a greater risk of having a fatal accident before age one; and finally, a greater probability of starting one's own family at an early age. Although there are variations from study to study, most studies that survey a representative sample from a population that has had no special interventions and is of diverse socioeconomic makeup, and that do not control for SES or other factors, find that children of teen parents are at greater risk than children of older parents for a host of health, social and economic problems.
