To determine the independent effects of maternal age and race/ethnicity on poor pregnancy outcomes, with and without controlling for other factors. ⋯ Maternal age at delivery and race/ethnicity are independently and significantly associated with poor pregnancy outcomes such as low birthweight and premature births. However, young maternal age and race/ethnicity do not appear to interact in a manner that produces a differential effect on the birth outcomes assessed in this study. The incidence of infant mortality is unrelated to maternal age or race/ethnicity, after controlling for prematurity and low birthweight, underscoring the importance of intervention efforts aimed at their prevention.

The aim of this study was to describe the prevalence of neck and shoulder symptoms among high school students and associated psychosocial factors. ⋯ Neck and shoulder symptoms are common among adolescents and psychosocial factors such as stress and depressive symptoms seem to be associated with these symptoms, especially among girls. More knowledge about the etiologic factors associated with neck and shoulder symptoms in adolescents may result in preventive programs with the potential for reducing morbidity of neck and shoulder symptoms in adulthood.
