Summary
Brief summary (as posted)
The development of chronic pain is one of the most seen sequelae in the cancer survivor population. Literature reports the presence of pain in approximately 40% of 5-year survivors. Specifically, in breast cancer survivors, chronic pain is estimated to be present in at least 50% of this population. On the other hand, chronic low back pain is one of the leading causes of disability and decrease in quality of life. It has huge economical, psychological and social impacts on individuals, society and health institutions. Unhealthy dietary behavior is associated with the occurrence, maintenance and management of chronic pain. Also, excessive calorie intake and diets rich in sugar, fat, sodium and caffeine were observed in patients having chronic pain. However, although nutritional factors are suggested as an associated lifestyle factor of chronic pain, limited attention is given to dietary and nutritional factors in relation to chronic pain. One particular mechanism drawing attention in the link between nutrition and pain are blood glucose levels and the glycemic response. Animal research shows the potential for reduced blood glucose to influence several pathways involved in chronic pain, including decreased oxidative stress, and reduced neuronal excitability. Given the link between blood glucose levels, as well as the evidence for the importance of interpersonal variability in the glycemic response, this glycemic response can also be of interest for chronic pain research. Finding a possible link between both the glycemic response and pain-related outcomes, could give direction to further research focussing on implementing (personalized) nutritional/dietary advise to maintain healthy blood glucose levels in people suffering from chronic pain. Therefore, this study will provide the first step in this promising line of research, by being the first to look for differences in glycemic response between breast cancer survivors having chronic pain and healthy pain-free controls, and between chronic low back pain patients and healthy pain-free controls. Secondly, this study will also investigate possible associations between glycemic response, pain-related outcomes, nutrition related outcomes, physical activity, and body composition for breast cancer survivors and chronic low back pain patients separately in comparison with healthy pain-free controls.
