Standing desks alongside other measures cut office workers' sitting time by an hour a day

Using a standing desk alongside a package of other measures to encourage office workers to sit less and move more, reduced sitting time by about an hour a day over one year, finds a trial published in The BMJ.

A growing body of evidence indicates that sedentary lifestyles are associated with higher levels of chronic disease, including heart diseases, type 2 diabetes, and some cancers, and higher rates of depression and anxiety.

No link between covid-19 vaccination in pregnancy and higher risk of preterm birth or stillbirth

Vaccination against covid-19 during pregnancy is not associated with a higher risk of preterm birth, small for gestational age at birth, or stillbirth, concludes a large study from Canada published by The BMJ.

Covid-19 infection during pregnancy has been associated with higher risks of complications, including admission to hospital and death for pregnant individuals, as well as preterm birth and stillbirth.Covid-19 vaccination during pregnancy has been shown to be effective against covid-19 in pregnant individuals as well as their newborns, but evidence about pregnancy outcomes after covid-19 vaccination during pregnancy from large studies is limited.
