13th Annual ACHORD Retreat
The 13th Annual ACHORD Retreat was held on March 10-11, 2016 at the Banff Centre. As in past years, this informal meeting provides an opportunity for ACHORD investigators, collaborators and trainees to share research activities, and plan for continued growth of the ACHORD group.
We would like to extend a special thank you to Fred Horne and Dev Menon who came to Banff to interact with our ACHORD group this year. We appreciated both of these individuals taking the time to come to our meeting and for presenting, along with Alun Edwards, a regular attendee, and Senior Medical Director with the Diabetes, Obesity and Nutrition Strategic Clinical Network (DON SCN). This session was very well received, and especially of value to our ACHORD trainees. We were also very fortunate to have Fred stay on for an additional question and answer session, which was originally for students, but everyone stayed to engage in the hour-long session.
As we typically do, we held an organized physical activity this year, a guided yoga class. We had a better turn out this year for yoga than last year. It was enjoyed by all of us who attended!
Thank you to everyone who attended the 13th Annual Retreat. As is the case every year, this event is a success because of those of you that attend. Special thanks to Sherry Lydynuik who helped Jeff Johnson in planning this year’s ACHORD retreat.
Report from the Chair
Hello everyone! Hope you have had a great year so far, nice to see the snow is gone and beautiful spring weather is upon us! I have been busy since returning from my sabbatical leave in January, as has everyone else in ACHORD! Here is a quick update on what we have been doing since our last newsletter.
As you can see from the first article in this newsletter, we held another successful ACHORD Retreat in Banff on March 10 & 11. This retreat was well attended, and we were very pleased to have Fred Horne, a former Minister of Health in Alberta, Alun Edwards, Senior Medical Director with the DON SCN, and Dev Menon, from the School of Public Health, share with us their wisdom on incorporating evidence into policy. The discussions were very insightful, and enjoyed by all. More information on the retreat will be available on our ACHORD website.
The newly established Alberta’s PROMs and EQ-5D Research and Support Unit (APERSU) continues to pick up steam as more groups are registering to use the EQ-5D. We held a Board of Directors teleconference in January and a Scientific Advisory Committee teleconference in early March. We updated members on our activities so far and gained excellent feedback from the members of both committees. We have subsequent teleconferences planned for the Scientific Advisory Committee in April and the Board of Directors in June. We have started to plan the second End User Meeting in November, 2016, in Edmonton. The EuroQol Foundation held a mid-year meeting in Amsterdam in which Fatima Al Sayah, Arto Ohinmaa and I attended on behalf of APERSU. We have done several presentations to various audiences around the province, to both academic and non-academic stakeholders. Our next presentation on campus will be on Monday, April 18 at the WCHRI Lunch & Learn, 12:00 pm in 4-036 ECHA. Our APERSU website is up and running, so please visit apersu.ca and follow us on Twitter @apersu1.
Our epidemiologic research on the relationship between diabetes and cancer continues, as you will see in our project update elsewhere in the newsletter. Chris Chen (MSc student), Samantha Bowker and I will be attending the annual Diabetes and Cancer Research Consortium (DCRC) workshop in Reykjavik, Iceland in April, where Chris will be presenting his thesis project results.
I hope the information in our newsletter is informative, and if you have any questions about our activities, please do not hesitate to contact us. I look forward to updating you in late summer/early fall with more on ACHORD’s activities.
Metformin, Ethnicity and Risk of Prostate Cancer
By: CB Chen, SR Majumdar, DT Eurich, and JA Johnson
There is a growing body of evidence suggesting individuals with diabetes are at an increased risk of cancer, triggering further studies investigating the ability of hypoglycemic agents to mitigate the risk. Our project aims to assess the impact of metformin exposure on prostate cancer risk and whether there are disparate effects between ethnic groups. We conducted a systematic review that did not find an association between metformin exposure and prostate cancer in Western- or Asian-based populations. However the pooled studies were highly heterogeneous hence we are conducting our own cohort study using an administrative database from British Columbia. Preliminary results do not suggest a relationship between metformin use and prostate cancer risk in Asian, Indian or other populations. A separate study using the same database also indicates that, as previously published, individuals with diabetes are at a lower risk of prostate cancer relative to those without. Although in both studies, there are indications of detection bias thus we will be investigating methods to mitigate this bias including adjusting for the number of physician visits and prostate specific antigen tests.
Recent Literature from the ACHORD Journal Club (Paper discussed Tuesday, March 1, 2016; Commentary by Ben Dubois)
Obesity and overweight have reached epidemic proportions and they are risk factors for the development of chronic disease. Fifty-nine million American adults are obese and 9 million young people are overweight, more than doubling in the last 20 years. Healthy dietary practices are important in preventing overweight and obesity, but although many Americans are adopting healthier diets, a gap remains between dietary recommendations and what is actually consumed. The need to promote healthy eating among young people is a public health priority.
Self-efficacy is important in health behaviors. Self-efficacy, the belief in ones’ ability to accomplish a task in varying circumstances, has been described as a generative capability in relationship to one’s social, environmental, cognitive, and personal circumstances (Bandura, 1997).
This month, we discussed this paper’s methods and conclusions on the use of internet based tools to promote self-efficacy and healthy eating in adolescent populations.
Study methods and summary
The study was conducted with a quasi-experimental pretest-posttest design in a random sample of students in two junior high schools, grades seven to nine. Schools were randomly assigned to an intervention consisting of a combination of 5 hours of Web-based instruction and 10 hours of classroom curriculum. The intervention group was compared to students who were randomly assigned to receive nutrition education embedded in the standard school curriculum during a 1-month period. Participants completed six questionnaires. Data were analyzed using descriptive statistics, t tests, and Pearson's r correlation coefficient.
The study concluded that the intervention group had significantly higher scores for self-efficacy for fruits and vegetables and lower fat, usual food choices, and dietary knowledge of fat compared to the control group. No difference was found between groups in food consumption. Self-efficacy was significantly associated with dietary knowledge of lower fat, and usual food choices. The intervention was tailored to the social and developmental preferences of adolescents and effectively increased self-efficacy for healthy eating. The mediating role of self-efficacy in the hypothesized model of adolescent eating behavior warrants further investigation.
The results of this study did not indicate a significant change in eating behavior in the intervention school, and several explanations are possible. The measurement of food consumption may not have been sufficiently sensitive to detect a significant change in eating behavior. The study’s resources were limited as well, which is why only a pretest-posttest design was used with questionnaires. The study was also limited to one month, and a comment was made in the discussion that the majority of diet interventions occur for three months or more, suggesting one month is not near long enough to produce any real results.
One major issue highlighted in our discussion is that the majority of reported conclusions are made based on the comparison between exposed and unexposed groups’ reported results at the end of the study. The issue with this kind of comparison is that the change in behaviour between the beginning of the study and the end in both groups is not taken into account in the calculation. This study shows the intervention group performed better than the control group, but only after the intervention, it is possible that the students assigned to the intervention may have had better habits before the study, and it is also possible that the students in the control group may have had worse habits before the study. Further to this issue, the researchers did not take the health or demographics of the children into account in the study, which may have had important influences on the students. It was also noted that this was an older study, and the conclusions may not have generalizability today, as both technology and testing methods have improved over time.
