N1 - This article is based on data from the study \u201CPelotas Birth Cohort, 2015\" conducted by the Postgraduate Program in Epidemiology at Universidade Federal de Pelotas, with the collaboration of the Brazilian Public Health Association (ABRASCO). The first phases of the 2015 Pelotas Birth Cohort (Brazil) were funded by the Wellcome Trust (095582). Funding for specific follow-up visits was also received from the Conselho Nacional de Desenvolvimento Cient\u00EDfico e Tecnol\u00F3gico (CNPq), Funda\u00E7\u00E3o de Amparo a Pesquisa do Estado do Rio Grande do Sul (FAPERGS), and Children\u2019s Pastorate sponsored follow-up at 24 months and FAPERGS \u2013 PPSUS, the Wellcome Trust (10735_Z_18_Z), and the Bernard van Leer Foundation (BRA-2018-178) for the 48 months follow-up.

N2 - Objective: To describe physical activity (PA), sleep, and rhythm patterns during 24-hr cycles from the second trimester of pregnancy up to 2 years after childbirth. Methods: This longitudinal study used data from mothers of the 2015 Pelotas Birth Cohort (Brazil). Women were invited to wear the accelerometer during 7 days on the nondominant wrist during the second trimester of pregnancy and 2 years after childbirth. Data collected included PA, sleep, and rhythm variables. We compared the means/medians of variables during the pregnancy and 2 years after the childbirth. We also describe the shape of acceleration across the day in the two evaluated periods and stratified this curve according to covariables. Results: This study includes data from 1,293 women with valid accelerometer data for both periods. The nonbouted moderate-to-vigorous PA average was 94 min during pregnancy and increased to 122 min 2 years after childbirth (p < .001). Sleep decreased by 11 min (388–377 min; p < .001) in the evaluated period. The pattern of acceleration across the day did not change in the evaluated period with two marked spikes of activity at 10 a.m. and 6 p.m. The amount of activity, however, increased. Conclusions: These findings may be helpful to better understand changes in PA and sleep during this specific period of life and assist in planning recommendations.
