Background/objectives Microvascular changes may contribute to obesity-associated cardiovascular disease. We examined whether body mass index (BMI) and waist-to-height ratio (WHtR) (1) at multiple earlier time points and (2) decade-long trajectories predicted retinal microvascular parameters in mid-childhood/adulthood. Methods Participants/design: 1288 11–12 year olds (51% girls) and 1264 parents (87% mothers) in the population-based Child Health CheckPoint (CheckPoint) module within the Longitudinal Study of Australian Children (LSAC). LSAC exposure measures: biennial BMI z-score and WHtR for children at five time points from age 2–3 to 10–11 years and self-reported parent BMI at six time p..View full abstract

This study uses data from the Longitudinal Study of Australian Children (LSAC) and Child Health CheckPoint. We thank the LSAC and CheckPoint study participants and families. We also thank the CheckPoint team and the Murdoch Children's Research Institute. LSAC is conducted in partnership between the Department of Social Services (DSS), the Australian Institute of Family Studies (AIFS), and the Australian Bureau of Statistics (ABS). The findings and views reported in this paper are those of the authors and should not be attributed to DSS, AIFS, or the ABS. MW and ML had full access to all the data in the study and take responsibility for the integrity of the data and the accuracy of the data analysis.
