Differences between Undergraduate and Graduate Students in Stress and Coping Strategies

Background and Purpose: Stress among college students, and the related health and academic consequences, remains an important issue for college health professionals. Yet, less is known about the reported coping strategies among both undergraduate and graduate students. Purpose: This crosssectional study examined differences between undergraduate and graduate college students in stress levels and coping behaviors. Methods: An online health behavior survey was administered to a random sample of 1,139 college students enrolled in 2011. Chi-square test of independence examined demographic differences, stress levels and coping strategies. Classification and Regression Tree analysis further explored coping strategies which differentiated groups. Results: Participants were primarily white (87.2%), graduate students (58.5%), and female (59.8%). Almost 80% reported moderate, much or great deal of stress, with no significant differences between undergraduate and graduate students. Sleep (69.6%), exercise (66.1%), and food (56.8%) were the most common coping strategies, regardless of academic classification. Social support as a coping strategy was the most important variable explaining differences between undergraduate and graduate students. Conclusion: Undergraduate and graduate college students cope with stress in a similar manner. However, social support was more likely among graduate students and may be an important strategy for future college health programming

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
