Body mass index trajectory across childhood and subsequent risk of elevated blood pressure.

ABSTRACT: We investigated the relationship between the body mass index (BMI) trajectory across childhood and the subsequent occurrence of elevated blood pressure (BP) in the Chinese pediatric population. The study cohort from the China Health and Nutrition Survey comprised 1484 children, each of whom underwent three BP and BMI assessments during childhood and had a non-elevated BP during the first childhood assessment. A group-based trajectory model was used to identify four distinct BMI trajectories across childhood: lean-stable increase, medium-marked increase, heavy marked decrease, and heavy marked increase. Elevated BP in childhood was as defined in the China's national BP reference for children. Covariate-adjusted logistic regression models were used to assess the associations of BMI trajector
