Introduction: Home-based records (HBRs) are widely used for recording health information including child immunisations. We studied levels and inequalities in HBR ownership in low-income and middle-income countries (LMICs) using data from national surveys conducted since 2010.
Methods: We used data from national household surveys (Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS)) from 82 LMICs.
To evaluate the cross-sectional association of physical activity during pregnancy with gestational weight gain and verify if associations are modified by levels of sleep duration and efficiency. Mothers who were participants of the 2015 Pelotas (Brazil) Birth Cohort study were analyzed. Physical activity (PA) and sleep were measured using the nondominant wrist accelerometer model wGT3X-BT (ActiGraph, Pensacola, FL).

A score was used to evaluate UPF consumption, calculated by summing the positive answers to questions about the consumption of ten UPF subgroups on the previous day. Scores ≥5 represented high UPF consumption.

Utilizing data from The 2004 Pelotas (Brazil) Birth Cohort, sleep time window and sleep efficiency were measured at the 11-year-old follow-up using ActiGraph accelerometers. Three sleep PGSs were developed based on the most recent genome-wide association study of accelerometer-based sleep measures.
