Background

Cecilie Dahl is a researcher in epidemiology. She is currently engaged in the project «Norwegian Capture the Fracture – NoFRACT», where epidemiologists use register data to measure the effect of an intervention to prevent recurrent fractures in hospitalized patients. In addition she is administering the NOREPOS project "Climate, air pollution and fracture risk" in the Norwegian population.

Previous experience:

Research on gut microbiota at the Department of Environmental Exposure and Epidemiology, Norwegian Institute of Public Health (NIPH).
In 2014, successfully defended her thesis, with the topic “Drinking water quality and fractures in the Norwegian population” at the NIPH, using data from the Norwegian Epidemiologic Osteoporosis Studies (NOREPOS).
In 2007, earned a dual master’s degree in epidemiology and global health from Columbia University, and has worked as an epidemiologist in a low-income country (Rwanda), through the Millennium Village/ Access Project.
Bachelor of Science in Microbiology (summa cum laude) from San Diego State University, has worked as a microbiologist in the pharmaceutical industry, and in research

Increased mortality in hip fracture patients living alone: A NOREPOS study. Journal of Bone and Mineral Research. ISSN 0884-0431. s 1- 10 . doi: 10.1002/jbmr.4212 Full text in Research Archive. Show summary
Hip fracture is associated with excess mortality, persisting for many years after the fracture. Several factors may affect survival; however, the role of social support has been less studied. Living situation could be an indicator of a person's social support, which predicts mortality in the general population. In this longitudinal cohort study, we considered whether living alone was a risk factor for post-hip fracture mortality compared with living with a partner. Information on hip fractures from all hospitals in Norway from 2002 to 2013 was combined with the 2001 National Population and Housing Census. The association between living situation and mortality during 12.8 years of follow-up in 12,770 men and 22,067 women aged 50 to 79 years at fracture was investigated using flexible parametric survival analysis. We also estimated relative survival of hip fracture patients compared with that of the non-fractured background population in the same living situation (alone or with a partner). Higher mortality after hip fracture was found in both men and women living alone versus with a partner (hazard ratio [HR] men = 1.37, 95% confidence interval [CI] 1.29—1.44; HR women = 1.23, 95% CI 1.18—1.28, adjusting for age, education level, urbanization degree, and number of children). We demonstrated the strongest association in male hip fracture patients aged <60 years (long-term mortality HR = 3.29, 95% CI 2.25—6.49). Compared with the general population, relative survival 8 years after a hip fracture was 43% in men and 61% in women living alone, whereas relative survival in those living with a partner was 51% in men and 67% in women. In conclusion, hip fracture patients who lived alone had higher mortality than those living with a partner and lower survival relative to the general population.
