Background: The gendered division of labour contributes to differences in the way time is spent and experienced by women and men. Time spent in paid and unpaid labour is associated with sleep outcomes, therefore, we examined (i) the relationships between time use and time pressure, and sleep, and (ii) whether these relationships were modified by g...

The Nordic countries offer an ideal case study of the COVID-19 pandemic due to their comparability, high data quality, and variable mitigations. We investigated the age- and sex-specific mortality patterns during 2020-2021 for the five Nordic countries and analysed the total age- and sex-adjusted excess deaths, ratios of actual to expected death ra...

Abstract Occupational class differences in leisure‐time physical activity (LTPA) are well recognized. Less is known about how these differences develop as individuals age, and how retirement is associated with this change. We investigated how occupational class differences in LTPA change in a cohort over a 15‐17 year follow‐up . We further examined...

Background: The Nordic countries are an ideal case study of the COVID-19 pandemic due to their comparability, high data quality, and variable responses.

Sosioekonominen asema on keskeinen ruokatottumuksia määrittelevä tekijä. Työikäisessä väestössä alempi sosioekonominen asema on yhdistetty esimerkiksi vähäisempään kasvisten, hedelmien ja marjojen käyttöön sekä heikompaan kokonaisruokavalion laatuun. Ruokatottumusten sosioekonomisia eroja vanhuuseläkkeelle siirtymisen jälkeen on kuitenkin tutkittu...
