Do summaries of evidence enable informed decision-making about COVID-19 and influenza vaccination equitably across more and less disadvantaged groups? Study protocol for a multi-centre cluster randomised controlled trial of 'fact boxes' in health and social care in Germany.

Introduction: Evidence summaries on the benefits and harms of treatment options support informed decisions under controlled conditions. However, few studies have investigated how such formats support decision-making across different social groups. There is a risk that only disadvantaged people will be able to make informed health decisions-possibly increasing the health equity gap.

Fact boxes that inform individual decisions may contribute to a more positive evaluation of COVID-19 vaccinations at the population level.

Objective: For an effective control of the SARS-CoV-2 pandemic with vaccines, most people in a population need to be vaccinated. It is thus important to know how to inform the public with reference to individual preferences-while also acknowledging the societal preference to encourage vaccinations. According to the health care standard of informed decision-making, a comparison of the benefits and harms of (not) having the vaccination would be required to inform undecided and skeptical people.

How to improve health literacy to reduce short- and long-term consequences of maternal obesity?

To demonstrate the global challenge of maternal obesity and to propose models to increase awareness and health literacy. The regional perinatal data base and the international literature were reviewed to demonstrate the rising rates of maternal overweight and obesity causing major public health problems in low and high-resourced countries. A preliminary systematic review analyzing interventions in maternal obesity and a fact box based on a recent Cochrane review on dietary interventions were performed.
