• Sleep and physical activity changes are common in pregnancy, but longitudinal data starting before conception are scarce. Our aim was to determine the changes of the daily total sleep time (TST) and physical activity duration (PAD) from before conception to end of pregnancies in respect of pregestational maternal factors. This longitudinal observational study formed part of the CONIMPREG research project and recruited healthy women planning to become pregnant. Sleep and physical activity were recorded around-the-clock for ≥4 days via actigraphy before conception and during each trimester of pregnancy. Data were adjusted according to pregestational maternal body composition, parity and age. Among 123 women with eligible data, the unadjusted mean (95% confidence interval) TST increased from 415.3 min (405.5–425.2 min) before conception to 458.0 min (445.4–470.6 min) in the 1st trimester, remaining high through the 2nd and 3rd trimesters. Variation was substantial before conception (±2SD range: 307–523 min). The unadjusted mean PAD before conception was 363.7 min (±2SD range: 120–608 min), decreasing sharply to 262.1 min in the first trimester and more gradually thereafter. Vigorous and moderate activity decreased more than light activity. TST and PAD were significantly associated with age, parity, and pregestational body fat percentage; lean body mass was negatively correlated with TST. Results were generally unaffected by seasonal variations. Marked variations were found in pregestational TST and PAD. Healthy women slept ≥30 min longer during pregnancy, while PAD decreased by ≥ 90 min in early pregnancy and continued to decrease thereafter. •Healthy fertile women sleep 6 h 47 min–8 h 43 min (5–95 percentile).•When pregnant, they sleep ≥30 min longer and have ≥90 min less physical activity.•Previous childbirth is associated with less sleep and about 90 min more activity.•Sleep and physical activity variation is linked to pregestational body composition.•Seasonal variations do not influence gestational changes of the total daily sleep.
