The Effect of Cognitive–Behavioral Therapy as an Antidepressive Treatment Is Falling: Reply to Ljòtsson et al. (2017) and Cristea et al. (2017)
No full textThis article critically reassesses the nonlinear reanalysis by Ljótsson, Hedman, Mattsson, and Andersson (2017) and reviews Cristea et al.’s (2017) extension of our original meta-analysis (Johnsen & Friborg, 2015) reporting a decline in the effects of cognitive–behavioral therapy (CBT) for treating unipolar depression. Ljótsson et al. fitted a piecewise meta-regression model to the data, indicating a halt in the decline from the year 1995 onward, hence concluding that CBT is not gradually losing its efficacy. We reanalyzed the data for nonlinear time trends and replicated their findings for the 34 studies using the Hamilton Rating Scale for Depression as the outcome but not for the 67 studies using Beck’s Depression Inventory as the outcome. The best nonlinear model was quadratic rather than flat (or linear) from 2001 onward, which opposes the conclusion by Ljótsson et al. of stability in effects. Cristea et al. identified additional studies, but their new analyses provided mixed support for a linear decline in CBT effects. They could not dismiss a decline except only in the most stringent analytic condition—namely, when analyzing only 29 randomized controlled trials based on between-groups effect sizes solely. Their study includes several questionable methodological choices, so we expand on the discussion of these disparate meta-analytic findings. Of particular concern is the tendency to downplay the fact that when looking at all of the studies together, there is a clear decline in the effects of CBT, which should concern therapy researchers within the field rather than being explained away
The Danish national type 2 diabetes cohort – the DD2 study

This supplemental issue of Clinical Epidemiology describes the rationale, design, and implementation of the establishment of a large cohort of all Danes with type 2 diabetes (the DD2 study) and of a biobank to bridge the scientific disciplines of epidemiology, clinical medicine, genetics, epigenetics, and pharmacology. This will most likely result in great benefits for the application of evidence-based medicine to the care of, and improved outcomes for, Danish type 2 diabetes patients
The Healthy Body Image intervention: A school-based, cluster-randomized controlled trial in high school students
No full textAvhandling (doktorgrad) - Norges idrettshøgskole, 2020Background: Researchers have been encouraged to design and evaluate health promotive interventions specifically tailored to promote positive embodiment in adolescents because it is associated with important mental and physical health outcomes. Furthermore, because positive embodiment and healthy lifestyle habits are related phenomena, stimulating positive embodiment should also promote healthy lifestyle habits. It has been indicated that school-based, interactive, multicomponent interventions could be effective. However, few studies have implemented all the necessary criteria for a sound methodology: a study with a clustered-randomization, a controlled design; a large sample size, including both genders; a long-term follow-up; and a measurement of the promotion of positive embodiment, not only the lack of dissatisfaction or symptoms of eating disorder pathology. Additionally, more studies that investigate which constructs that need to be influenced in order to improve positive embodiment are needed, to further tailor content for the best possible intervention effect on boys and girls. The Healthy Body Image (HBI) intervention was a response to the lack of evidence in this field and to the reported gaps related to methodological quality.
Objectives: The primary objective of the thesis is to evaluate the effects of the HBI intervention on high school boys and girls. The first paper outlines the rationale and the specific study protocol for the intervention. The second paper examines both the short- and long-term effects of the intervention on positive embodiment and health-related quality of life (HRQoL), as well as the moderating effect of workshop attendance on intervention effects in boys and girls. The third paper evaluates whether the intervention has an additional effect on lifestyle habits, such as physical activity, eating, and sleep, in the same sample. The fourth paper examines whether the intervention affected positive embodiment through specific constructs such as, internalization, social media usage, self-compassion, self-esteem, and body image flexibility that the intervention aimed to target.Paper I: Sundgot-Borgen, C., Bratland-Sanda, S., Engen, K.

Cancer among the circumpolar Inuit, 1989–2003. I. Background and methods
No full text"Objectives: This is first of 2 papers on the Circumpolar Inuit Cancer Review, an international collaborative effort involving researchers and health officials from Alaska, Canada and Greenland. It covers the period 1989–2003, updating the last review (1969-1988) and together provides an overview of the trends and patterns of cancer among the Inuit in 3 countries and over a 35-year period. Methods: Inuit cancer cases by age-sex group and anatomic site were obtained from the regional cancer registries. The sources of the age-sex distribution of various Inuit populations include the population registry (Greenland), and annual estimates and periodic censuses (Alaska and Canada). Incidence rates were age-standardization by the direct method to the standard world population of the International Agency for Research on Cancer. Conclusions: This project demonstrates the feasibility of international partnerships in cancer surveillance, and when these partnerships are extended to other diseases and health conditions, they can contribute to the development of a Circumpolar Health Observatory."

Cancer among the circumpolar Inuit, 1989–2003. II. Patterns and trends
No full text"Objectives: This is the second of 2 papers reporting on the result of the Circumpolar Inuit Cancer Review, an international collaborative effort involving researchers and health officials from Alaska, Canada and Greenland. Methods: Inuit cancer cases by age-sex group and anatomic site were obtained from the regional cancer registries. Results. Cancer in general is increasing among Inuit, in all regions, and among both men and women. Inuit continue to be at extreme high risk, relative to non-Inuit and to comparisons of global populations, for the historically recognized so-called traditional cancers (such as cancer of the nasopharynx and salivary glands). Among the so-called modern cancers prevalent in developed societies, lung cancer is rapidly increasing in incidence (especially in Canada), such that the rate in both Inuit men and women is the highest in the world; other cancers, such as colorectal cancer, are also on the rise (especially in Alaska), while breast and prostate cancer remain low relative to the non-Inuit population."
