OBJECTIVE: To identify classes of balance skills and their trajectories from childhood to adolescence and the association of birthweight with these trajectories.
STUDY DESIGN AND SETTING: Participants (n = 13,443) from the 1970 British Cohort Study were assessed for four balance skills in childhood and adolescence. Latent class analysis was used to determine classes of balance skills over time, and latent transition analysis was used to explain the association between birthweight and the probabilities of changing classes over time.
RESULTS: A three-class solution, good balance skills (GBS) group, intermediate in balance skills (IBS) group, and poor balance skills (PBS) group, best fit the data for both childhood and adolescence. Most (49.97%, n = 6.713) had GBS in childhood and GBS in adolescence; the probability of "staying" as GBS was 86%. Birthweight was associated with higher likelihood of remaining GBS at adolescence (OR = 1.82, 95% CI = 1.40-2.37). Those who were classified as IBS and PBS in childhood had 75.2% and 62.7% probability of becoming GBS in adolescence, respectively. A small percentage of children stayed in the PBS group (1.92%, n = 258), with probability of remaining as such being 15.1%.
CONCLUSIONS: The higher the birthweight, the better the outcomes in those with GBS and IBS in the childhood. However, although small proportion of children stayed at the lowest level of balance skills in adolescence, some clinical attention should be given to those classified at this level in childhood.
