RESUMO

A healthy diet plays a key role in preventing obesity and non-communicable diseases such as type 2 diabetes. This is true for all age groups, including young adults. While unhealthy eating habits among young adults, in particular university students, have been identified in former studies, this group has been neglected in existing health promotion strategies. Our aim was to explore baseline dietary intake, common barriers to healthy eating, and changes in eating behaviour among university students since the time of matriculation. We used data from the quantitative part of the Nutrition and Physical Activity Study (NuPhA), a cross-sectional online survey (data collection: 2014/10/31-2015/01/15). Students were recruited from all over Germany. Overall, 689 university students (30.5% male; mean age: 22.69) from more than 40 universities across Germany participated. We found that there is room for improvement with regard to the consumption of specific food groups, for example, fruits and vegetables. The main barriers to healthy eating were lack of time due to studies, lack of healthy meals at the university canteen, and high prices of healthy foods. Cluster analysis revealed that barriers to healthy eating might affect only specific subgroups, for instance freshmen. Changes in eating behaviour since matriculation were found in the consumption of meat, fish, and regular meals. Future qualitative studies may help to explore why university students change their eating behaviour since the time of matriculation. Such knowledge is necessary to inform health promotion strategies in the university setting.

RESUMO

The transition from adolescence to adulthood is associated with many physical, social, and psychological changes. In addition, adolescents also have to deal with structural changes. An example of one such structural change is the transition from school to university or to other vocational establishments. Structural changes can also entail changes in overall framework conditions and daily life patterns and thus also in dietary habits and physical activity levels. The aim of the present paper was to draw attention to the research deficit in this area with the help of the results of our analyses. The results show that significant changes take place as a consequence of the transition from school to a vocational establishment. However, our analyses could not identify the exact catalysts and the time framework of these changes. In this respect, further research is urgently warranted.

RESUMO

Vitamin D deficiency is associated with osteoporosis and is thought to increase the risk of cancer and CVD. Despite these numerous potential health effects, data on vitamin D status at the population level and within key subgroups are limited. The aims of the present study were to examine patterns of 25-hydroxyvitamin D (25(OH)D) levels worldwide and to assess differences by age, sex and region. In a systematic literature review using the Medline and EMBASE databases, we identified 195 studies conducted in forty-four countries involving more than 168 000 participants. Mean population-level 25(OH)D values varied considerably across the studies (range 4·9-136·2 nmol/l), with 37·3 % of the studies reporting mean values below 50 nmol/l. The highest 25(OH)D values were observed in North America. Although age-related differences were observed in the Asia/Pacific and Middle East/Africa regions, they were not observed elsewhere and sex-related differences were not observed in any region. Substantial heterogeneity between the studies precluded drawing conclusions on overall vitamin D status at the population level. Exploratory analyses, however, suggested that newborns and institutionalised elderly from several regions worldwide appeared to be at a generally higher risk of exhibiting lower 25(OH)D values. Substantial details on worldwide patterns of vitamin D status at the population level and within key subgroups are needed to inform public health policy development to reduce risk for potential health consequences of an inadequate vitamin D status.
