Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Previous studies have reported associations between obesity, chronic pain and increased pain sensitivity. The adipokine leptin has been suggested to be involved in the osteoarthritis process as well as in pain sensitisation.ObjectivesThe aim was to study associations between chronic widespread pain, pain sensitivity and leptin in individuals with knee pain.MethodsIn all, 306 individuals with knee pain were included in the Halland osteoarthritis cohort, ClinicalTrials.gov NCT04928170. Of those, 265 were included in this cross-sectional baseline study. The mean age (sd) was 51.6 (8.8) years, and 71% was women. The participants marked their painful areas on a pain figure with 18 predefined areas. They were categorised in three different pain groups according to the modified WP2019 definition (1), with knees excluded (due to highest goodness of fit): Chronic widespread pain (CWP), chronic regional pain (ChRP) if CWP was not met, and no chronic pain (NCP). The group with CWP were compared with those reporting no CWP (ChRP and NCP). The pressure pain thresholds (PPT) were measured using a computerised pressure algometry (AlgoMed, Medoc) on eight predefined tender points (trapezius (bilateral), right second rib, right lateral epicondyle, knees, gluteal (bilateral)) (2). Increased pain sensitivity was defined as having PPT in the lowest third in all tender points. Obesity was measured via waistline measurement and a bioimpedance (InBody 770) measuring BMI and visceral fat area (VFA). Serum-Leptin were analysed with an ELISA method (Alpco). Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to describe the groups.ResultsIn this baseline study, 16% reported CWP, and 15% had low pain pressure thresholds at baseline in the study. Those fulfilling CWP were more often women, had higher BMI, VFA, and increased leptin levels and worse KOOS in four of five subscores, see Table 1A. The age and gender-adjusted leptin levels were 21.6 ng/ml (95% CI 18.2-25.0) in the group with no CWP vs. 35.5 ng/ml (95% CI 27.6-43.4) in the CWP group, p=0.002. In a logistic regression adjusting for age and gender, leptin was associated with reporting CWP OR 1.015 (95% CI 1.004-1.027, p= 0.008).Table 1.A Comparisons between those without CWP and those fulfilling CWP and table 1B comparisons between those not having low PPT and those with low PPT.ABNo CWPMean (sd)CWPMean (sd)p-valueNot Low PPTMean (sd)Low PPTMean (sd)p-valuen2104022639Age51.8 (8.7)52.8 (7.6)0.46552.1 (8.5)48.8 (9.9)0.030Gender, female n(%)67900.00472670.524BMI (kg/m2)26.2 (4.6)28.0 (5.0)0.02226.4 (4.9)27.5 (4.3)0.213VFA (cm2)107 (50)137 (56)0.001110 (54)127 (49)0.088Leptin (ng/ml)21.0 (23.9)39.0 (36.6)<0.00123.0 (26.0)31.8 (31.6)0.061CRP (mg/L)1.9 (2.7)2.2 (2.3)0.6022.0 (2.7)1.9 (1.8)0.825KOOSPain (0-100, worst to best)74 (15)61 (17)<0.00173 (15)65 (18)0.002Symptom (0-100, worst to best)72 (17)64 (18)0.01671 (17)67 (19)0.188ADL (0-100, worst to best)84 (13)69 (19)<0.00184 (14)72 (21)<0.001Sport/rec (0-100, worst to best)49 (26)34 (27)0.00149 (26)36 (25)0.009QoL (0-100, worst to best)53 (18)46 (20)0.05053 (18)45 (21)0.017BMI, body mass index; VFA, visceral fat area; CRP, C-reactive protein; KOOS, knee injury and osteoarthritis outcome score; ADL; function in daily living; sport/Rec, Function in sport and recreation; QOL, knee-related Quality of lifeThe participants with low PPT were younger and had a mean (sd) leptin 31.8 ng/ml (31.6) vs 23.0 (26.0), p=0.061 in the group not having low PPT, Table 1B.

The adipokine leptin could be involved in some of these mechanisms, but longitudinal studies are needed to be able to study causal relationships.References[1]Wolfe F, et al.

The participants marked their painful areas on a pain figure with 18 predefined areas. According to their answer, they were categorised in three different pain groups according to the modified WP2019 definition (1), with knees excluded (due to highest goodness of fit): Chronic widespread pain (CWP), chronic regional pain (ChRP) if CWP was not met, and no chronic pain (NCP). The groupwith CWP were compared with those reporting no CWP (ChRP and NCP). The pressure pain thresholds (PPT) were measured using a computerised pressure algometry (AlgoMed, Medoc) on eight predefined tender points (trapezius (bilateral), right second rib, right lateral epicondyle, knees, gluteal (bilateral)) out of the total 18 points that are part of the definition of fibromyalgia (2). Increased pain sensitivity was defined as having PPT in the lowest third in all tender points. Obesity was measured via waistline measurement and a bioimpedance (InBody 770) measuring BMI, visceral fat area (VFA), and body fat percentage. Serum-Leptin were analysed with an ELISA method (Alpco). C-reactive protein (CRP) >1.0 mg/L were measured according to the current laboratory standards in Sweden. CRP below 1.0 mg/L, were further analysed with a sensitive CRP enzyme-linked immunosorbent assay (ELISA) method (Abnova). Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to describe the groups.Result: In this baseline study, 16% reported CWP, and 15% had low pain pressure thresholds at baseline in the study. Those fulfilling CWP were more often women, had higher BMI, VFA, and increased leptin levels and worse KOOS in four of five subscores, see table 1A. The age and gender-adjusted leptin levels were 21.6 ng/ml (95% CI 18.2-25.0) in the group with no CWP vs. 35.5 ng/ml (95% CI 27.6-43.4) in the CWP group, p=0.002. In a logistic regression adjusting for age and gender, leptin was associated with reporting CWP OR 1.015 (95% CI 1.004-1.027, p= 0.008).The participants with low PPT were younger and had a mean (sd) leptin 31.8 ng/ml (31.6) vs 23.0 (26.0), p=0.061 in the group not having low PPT, table 1B. In a logistic regression adjusting for age and gender, leptin was associated with low PPT OR 1.016 (95% CI 1.004-1.029, p= 0.012).There were no increased CRP levels in any of the pain groups (CWP and low PPT), table 1A and B.Conclusion: The pathophysiological mechanism causing widespread pain is probably multifactorial, involving both biological and physical factors. The adipokin leptin could be involved in some of these mechanisms, but longitudinal studies are needed to be able to study causal relationships.

- OBJECTIVE: The aim was to study associations between chronic widespread pain, widespread pain sensitivity, leptin, and metabolic factors in individuals with knee pain. A secondary aim was to study these associations in a subgroup of individuals with normal BMI.METHOD: This cross-sectional study included 265 individuals. The participants were categorised into three different pain groups: Chronic widespread pain (CWP), chronic regional pain (ChRP), or no chronic pain (NCP). The pressure pain thresholds (PPTs) were assessed using computerised pressure algometry. Low PPTs were defined as having PPTs in the lowest third of all tender points. Leptin and metabolic factors such as BMI, visceral fat area (VFA), lipids, and glucose were also assessed.RESULT: Sixteen per cent reported CWP, 15% had low PPTs, and 4% fulfilled both criteria. Those who fulfilled the criteria for CWP were more often women, more obese, and had increased leptin levels. In logistic regression, adjusted for age and gender, leptin was associated with fulfilling criteria for CWP, OR 1.015 (95% CI 1.004-1.027, p = 0.008). In logistic regression, adjusted for age and gender, leptin was associated with low PPTs, OR 1.016 (95% CI 1.004-1.029, p = 0.012). Leptin was also associated with fulfilling both criteria, adjusted for age, sex, and visceral fat area (VFA), OR 1.030 (95% CI 1.001-1.060), p = 0.040.CONCLUSION: Leptin was associated with fulfilling the combined criteria for chronic widespread pain and low PPTs, even after adjusting for the visceral fat area (VFA). Longitudinal studies are needed to study the causal relationships between leptin and the development of widespread pain.

- The COVID-19 pandemic has affected the health and lifestyles of both the general population and of vulnerable groups. Individuals with knee pain are recommended to lead an active lifestyle to relieve pain but find it difficult to maintain health and lifestyle compared to the general population due to the cause of chronic pain, impaired physical function, and a diminished quality of life. This study aimed to explore experiences of how health and lifestyle among individuals with knee pain have been influenced during the COVID-19 pandemic. Interviews (n = 19) were conducted in 2021 and analysed with qualitative content analysis. The results showed how individuals with knee pain adjusted their behaviour and revalued their life to maintain health and lifestyle during COVID-19. Adjusted behaviours emerged, such as spending more time at home, becoming digital, and spending more time outdoors, while revaluing life emerged as having a positive outlook on life and sharing responsibility. In conclusion, behaviour was adjusted, and life revalued to manage health and lifestyle during the pandemic. However, the findings are probably similar to the general population, i.e., individuals with knee pain live similar lives as the general population despite knee pain. The results may contribute to alternative ways of maintaining health and lifestyle in various vulnerable groups and may be applied in situations other than the pandemic. © 2022 by the authors.

- Background: The covid-19 pandemic has affected health and lifestyle among the general population and vulnerable groups. Individuals with knee pain are recommended an active lifestyle to reveal pain but find it difficult to maintain health and lifestyle compared to the general population due to the cause of chronic pain, impaired physical function, and a diminished quality of life. This adds to the importance of exploring how to preserve health and lifestyle among individuals with knee pain during the pandemic. Objective: The aim of this study was to explore experiences of how health and lifestyle among individuals with knee pain have been influenced during the covid-19 pandemic.Method: Nineteen participants with current knee pain, with no earlier diagnosed radiographic osteoarthritis, and no rheumatologic disorder or cruciate ligament injury, were recruited from The Halland Osteoarthritis (HALLOA) Cohort Study, twelve females and seven males, between 41-62 (median 51) years of age. Data were collected through individual interviews with open-ended questions: “What impact have you experienced with your health and lifestyle during the covid-19 pandemic?”, and “What activities or strategies have you changed to maintain your health and lifestyle during the covid-19 pandemic? ”. Qualitative content analysis was used, where two categories and five sub-categories emerged (Table 1). Result: The result from this study explored how individuals with knee pain adjusted their behaviour and revalued their life to maintain health and lifestyle during the pandemic. The category adjusted behaviours emerged with the sub-categories: spending more time at home, becoming digitally and spending more time outdoors. These sub-categories determine how a more reclusive behaviour has appeared due to the pandemic, where digital platforms and outdoor activities have facilitated companionship and togetherness when feelings of loneliness and isolation were present. The category revaluing life emerged with the sub-categories: having a positive outlook on life and sharing responsibility. These sub-categories establish the importance of being grateful for maintaining health and lifestyle and being solution-oriented to find the best possible outcomes to continue with everyday life, despite the pandemic. While having a responsibility toward others arose as a facility to manage to keep social distance during the pandemic. Conclusion: In conclusion, individuals with knee pain managed their health and lifestyle during the pandemic by adjusting behaviors and revaluing life. Adapting to restrictions included spending more time at home and outdoors, becoming more digitally, and revaluing life by having a positive outlook on life and supporting others. The result may contribute to alternative ways of preserving health and lifestyle in different vulnerable groups and may be used in situations other than the pandemic.

- Knee pain is an early sign of knee osteoarthritis (KOA) and a risk factor for chronic widespread pain (CWP). Early prevention is vital, and more research is needed to understand health-promoting activities for individuals with knee pain from a patient perspective. This study aimed to explore how individuals with knee pain experienced health-promoting activities. Explorative qualitative design with inductive approach was applied to explore the experiences of 22 individuals (13 women, 9 men; median age: 52). Semi-structured interviews were conducted and analysed using latent qualitative content analysis. The results revealed health-promoting activities in individuals with knee pain and were interpreted in the overall theme, striving for balance in everyday life. Two categories explored the content in health-promoting activities: (1) Caring for the body—being physically active, having a healthy diet, and utilising support; and (2) Managing life stressors—allowing for recovery, promoting vitality, and safeguarding healthy relationships. In conclusion, individuals with knee pain described various health-promoting activities. They strived for balance in everyday life by caring for the body and managing life stressors. We suggest that a broader approach to everyday life can be helpful in treatment plans and health promotion to manage and prevent KOA and CWP, while striving for a healthy lifestyle.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Low health literacy is associated with worse pain and poorer self-management. This study (1) examined the level of health literacy and associations with lifestyle habits, health status, chronic pain, and radiographic knee osteoarthritis; and (2) explored experiences illuminating health literacy among individuals with knee pain.METHODS: A convergent parallel mixed-methods design was used, including 221 individuals. Health literacy was assessed by HLS-EU-Q16 and eHEALS. The questionnaire included questions on lifestyle habits, health status, and pain distribution. Radiographic knee osteoarthritis was assessed with x-rays. Associations were analysed using logistic regression analyses. Individual semi-structured interviews were conducted (n = 19) and analysed with qualitative content analysis.RESULTS: The result showed that 71% reported sufficient health literacy. Higher education, healthy lifestyle habits, better general health, and absence of widespread pain were associated with sufficient health literacy. Experiences regarding health literacy influencing the decision-making process toward a decision on action comprised: (1) searching for information actively or passively; (2) processing of the information included being informed, critical, and interpretive; and (3) taking a stand on the information based on trustfulness and motivation.CONCLUSION: Seven out of 10 reported sufficient health literacy. Despite this, unhealthy lifestyles were common, suggesting that having sufficient HL is not enough for a behavioural change and the decision-making process, including different phases such as searching, processing, and taking a stand on health information is important to consider. More research on health literacy is needed to gain knowledge of how best to develop health promotion in individuals with knee pain. © 2023, BioMed Central Ltd., part of Springer Nature.

Health Promotion in Individuals with Knee Pain – Different Ways to Enable and Maintain a Balance in Everyday Life Based on the Abilities
- 2022

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Most individuals with knee pain develop radiographic knee osteoarthritis over time [1], and up to 30% develop chronic widespread pain (CWP) [2]. Many studies only focus on physical activity or weight loss when it comes to managing knee osteoarthritis (KOA) and chronic pain. There is a challenge to get more individuals to follow the existing recommendations for KOA, including physical activity and weight loss [3]. However, the interaction between the various physical, mental, and social factors regarding health promotion is complex. More research is needed to understand health-promoting activities applied amongst individuals with knee pain.Objectives: To explore health-promoting activities in individuals with knee pain.Methods: The study was a part of the Halland Osteoarthritis cohort (ClinicalTrials.gov NCT04928170), including 306 individuals with knee pain without earlier diagnosed KOA, cruciate ligament injury or other rheumatological disorder. A purposeful sample of 22 individuals (13 women, 9 men; median age 52 years) participated in the study. Ten had radiographic KOA, 12 had chronic regional pain, 9 reported CWP, 16 were overweight, and 13 met the WHO recommendations for physical activity with moderate intensity. Semi-structured interviews were conducted and followed a pilot-tested interview guide initiated with open-ended questions such as “What do you do to maintain your health?” and “What enables you to keep health?”. The interviewers followed the participants reasoning, and to obtain depth in the data, the participant received follow-up questions such as “Please, can you tell me more about…?”. The interviews were audio-recorded and transcribed verbatim. Data analysis was performed by latent qualitative content analysis and revealed an overall theme including two categories and six sub-categories.Results: Health-promoting activities in individuals with knee pain were interpreted in the overall theme; enabling and maintaining a balance in everyday life based on abilities. Two categories explored the content in health-promoting activities as 1) Using facilitators to take care of the body with the sub-categories: being physically active, having a healthy diet, and using external resources. For example, the participants took care of the body by being physically active to decrease pain, reducing sugar intake and using external resources such as online workouts or help from health care. 2) Managing stressors of everyday life with the sub-categories: promoting vitality, allowing for recovery, and safeguarding healthy relationships. The participants managed stressors of life by, for example, being in nature, planning their work- and private life and spending time with friends and family. See Table 1 Conclusion: Individuals with knee pain described various health-promoting activities, ranging from physical activity to social interactions, included in the theme of enabling and maintaining a balance in everyday life based on abilities. We suggest that a broader approach to everyday life can be helpful in treatment plans and health promotion to manage and prevent KOA and chronic pain while maintaining a healthy lifestyle.REFERENCES:[1] Thorstensson et al.
