Abstract

Background: To utilize the power of latent growth analysis to evaluate changes in postural sway during development in children who are either at high or low risk for developing alcoholism. Methods: A total of 629 assessments of postural sway have been performed in children and adolescents (n = 126) who were evaluated annually over a 7-year period. Results: Latent curve models indicated that these children/adolescents show a linear decrease in sway with age. Moreover, significantly different rates of change in the amount of sway between high- and low-risk offspring were seen. With the exception of one of the four stances tested, high-risk boys consistently showed a slower rate of improvement with respect to the amount of sway exhibited compared to low-risk boys. In girls, similar rates of improvement with age were seen in high- and low-risk individuals, though in one stance the high-risk girls showed a deterioration (greater sway with increasing age). Conclusions: Previous reports of increased postural sway in high-risk offspring most likely reflect a developmental delay (high-risk children have greater sway than is appropriate for their age based on normative values by age).
