In 1998, more than half of the adult population in Germany had serum 25-hydroxy-vitamin-D [25(OH)D] levels below the common threshold of 50 nmol/l. Since then, there has been a lot of attention for vitamin D in the scientific community, the media and the general population and serum 25(OH)D levels may have increased as a consequence. With data from the 'German Health Interview and Examination Survey for Adults' (DEGS1) the current situation of vitamin D status can be analysed. ⋯ Serum 25(OH)D levels below the threshold of 50 nmol/l are still common among adults in Germany, especially during winter and spring and in higher latitudes. Potentially modifiable factors of poorer vitamin D status are higher BMI, lack of sport activity and high media use.

Despite previous studies reporting spatial in equality in diabetes prevalence across China, potential geographic variations in diabetes mortality have not been explored. ⋯ Declines in diabetes mortality between 2006 and 2012 have been unequally distributed across China, which may imply differentials in diagnosis, management, and the provision of services that warrant further investigation.

Drowning is common worldwide. Rescue efforts attempted by untrained bystanders often lead to the death of the primary drowning victim (PDV), the rescuer or both. Our study aimed to inform prevention by identifying risk factors in rescuer drowning. ⋯ Most of the currently employed life-saving methods are dangerous and even potentially life threatening. The idea of "rescuers' safety first" should be embraced, especially with teenage and child rescuers, who should never be encouraged to rescue others without first guaranteeing their own safety. Promotion of basic rescue skills should be implemented in the general public.

Older adults and individuals with underlying chronic diseases are at increased risk of developing influenza-related complications and are target groups for seasonal influenza vaccination in many countries. In Germany, an annual national information campaign is conducted to increase influenza vaccination uptake in the target groups. However, data are lacking on knowledge and attitudes toward influenza vaccination among older adults and those with chronic diseases. The present study aimed to (i) estimate influenza vaccination uptake for the 2012/13 and 2013/14 seasons, (ii) assess knowledge and attitudes about influenza vaccination, and (iii) identify factors associated with vaccination uptake in two risk groups. ⋯ Influenza vaccination coverage rates in Germany remain low. Individual perceptions regarding harms and benefits are crucial in the decision-making process. Communication strategies should focus on improving understanding and perception of personal risks arising from the disease and the vaccination.

Tobacco consumption is a major risk factor for morbidity and mortality. The Saudi Ministry of Health started a national tobacco control program in 2002 with increased and intensified efforts after joining the World Health Organization Framework Convention for Tobacco Control in 2005. ⋯ Although the indicators of tobacco consumption in KSA are better than most of the countries of the Middle East region and high-income countries, there are many potential areas for improvement. Our findings call for the development and implementation of programs to prevent smoking initiation and encourage quitting. To achieve its health goals, KSA may consider increasing taxation on tobacco products as well as other measures.
