- Background: Chronic widespread pain (CWP) is common (population prevalence of approximately 10%) and has a significant impact on the individual, healthcare, and society. Currently little is known about the actual course of CWP over time, in particular the pathways to the development and maintenance of CWP. One useful way to understand these pathways is to identify common clusters of people who share pain trajectories. Such information is clinically useful to identify factors that predict development, persistence, and resolution of CWP.Objectives: To identify different longitudinal pain trajectories over a period of 21 years.Methods: A 21-year longitudinal open-population cohort of n=1858 adults (aged 20-74) who completed surveys relating to their pain status in at least three of the five time points 1995, 1998, 2003, 2007, and 2016. Pain status (presence of persistent pain) was ascertained from a report of painful regions (0-18) on a pain mannequin and categorised into: NCP (No chronic pain), CRP (Chronic regional pain) and CWP (chronic widespread pain). Latent Class Growth Analysis (LCGA) was carried out based on these categories. Participants were assigned to a trajectory cluster where the posterior probability was the highest. Model fit was assessed by statistical indices and clinical interpretations of clusters.Results: LCGA identified five clusters describing different pathways of NCP, CRP and CWP over the 21 years. The cluster “Persistent NCP” was the most common pathway (n = 1052, 57%) representing those with no chronic pain over the whole time period. The “Persistent CRP or Migration from CRP to NCP” cluster included 411 individuals (22%) representing a group with stable or improving regional pain. In the groups who were shown to increase pain status, the “Migration from NCP to CRP or CWP” cluster included 92 individuals (5%), and there were 184 individuals (10%) in the cluster “Migration from CRP to CWP” representing a group with regional pain who developed CWP. The final cluster “Persistent CWP” included 119 individuals (6%) representing those with stable CWP throughout the time period. Figure 1 presents the mean number of pain sites over time by cluster.Conclusion: This study showed that whilst half of adults report no chronic pain over 21 years, a substantial proportion develop CWP or have persistent CWP over this time period. Whilst a common trajectory was movement from chronic regional pain to no chronic pain, a pattern of improving CWP was not seen suggesting this is an uncommon trajectory. This is the first study to show long-term trajectories for CWP, and further work is now required to understand factors that may identify individuals at risk of worsening pain status and factors that might promote improvement. These identified pathways of chronic pain over a lifespan improve the understanding of long-term development of chronic pain and chronic widespread pain. © Aili et al. 2019. No commercial re-use.

- Background: Chronic widespread pain (CWP) is a common condition (approximately 10% prevalence), that affects women twice as often as men. There is a lack of knowledge in how different coping strategies relates to health status during CWP development in a general population.Objectives: To explore different ways of coping with CWP and to relate the different coping strategies to health-related factors, before and after developing CWP.Methods: A sequential explorative mixed methods study including 19 women 45-67 of age, who had reported CWP in a survey 2016, but not in 1995. Individual interviews were analysed with a phenomenographic approach, and resulted in four categories of coping strategies. These categories were further explored with regard to four dimensions of health status (physical function, bodily pain, vitality and mental health) as measured by SF-36 (0-100, a lower score indicates more disability) and sleep problems measured both in 1995, and 2016.Results: The qualitative analysis revealed four categories representing different coping strategies, where each woman was labelled by the most dominant category; the mastering woman, the persistent woman, the compliant woman and the conquered woman. The first two categories emerged as being active coping strategies, and the latter two as passive. Women with passive strategies reported significantly lower vitality (median 57.5 vs 75, p=0.007) and worse mental health (median 54 vs 93, p=0.021) in 1995, before they had developed CWP compared with those with active coping strategies. No differences were seen between the groups on physical function, bodily pain or sleep.In 2016, there were still a difference between the passive and active group regarding mental health (median 56 vs 80, p=0.022), but not for vitality (median 35 vs 40, p=0.707). No differences were seen between the groups on physical function or bodily pain. All eight women with passive strategies reported problems with sleep in 2016, as compared to 6 of the 11 women with active strategies (p=0.045).Conclusion: Women that reported CWP in 2016, but not in 1995, described both active and passive coping strategies. The qualitative findings were associated with differences in vitality and mental health already in 1995, before they had developed CWP. Further, those with passive coping strategies reported worse health with regard to mental health and sleep problems in 2016. Interestingly, the groups did not differ in bodily pain or physical function neither in 1995 nor in 2016, which implicates the importance for the clinician to take the typical coping strategy into consideration, when meeting these patients in clinical settings. © Aili, Bergman, Bremander, Haglund & Larsson 2019.

- Background: If localised pain represent one end of a pain spectra, with overall better general health, chronic widespread pain (CWP) and fibromyalgia represent the other end of the spectra with worse general health and more comorbidities with other somatic diseases and mental illness. Sleep problems and fatigue are common among individuals reporting CWP and previous research indicate that sleep problems may be an important predictor for pain prognosis.Objectives: The aim of this population-based study was to investigate if sleep problems and fatigue predict the onset of CWP 5 and 18 years later.Methods: In order to get more stable baseline classifications of CWP, a wash-out period was used, including only individuals who had not reported CWP (according to ACR 1990 criteria for fibromyalgia) at baseline (−98) and three years prior baseline (−95). In all, data from 1249 individuals entered the analyses for the 5 year follow-up (−03) and 791 entered for the 18 year follow-up (−16). Four parameters related to sleep (difficulties initiating sleep, maintaining sleep, early morning awakening and non-restorative sleep), and one parameter related to fatigue (SF-36 vitality scale) were investigated as predictors for CWP. Binary logistic regression analysis were used for analyses.Results: All investigated parameters predicted the onset of CWP five years later (problems with initiating sleep (OR 1.91; 1.16–3.14), maintaining sleep (OR 1.85; 1.14–3.01), early awakening (OR 2.0; 1.37–3.75), non-restorative sleep (OR 2.27; 1.37–3.75) and fatigue (OR 3.70; 1.76–7.84)) in a model adjusted for age, gender, socio-economy and mental health. All parameters except problems with early awakening predicted the onset of CWP also 18 years later. In all, 785 individuals did not report any of the sleeping problems at baseline (fatigue not included), 268 reported one of the problems, 167 two, 128 three and 117 subjects reported to have all four sleep problems. Reporting all four sleep problems was significantly associated with CWP at follow-up at both time points when adjusting for age, gender, socio economy and mental health (OR 4.00; 2.03–7.91 and OR 3.95; 1.90–8.20); adjusting for age, gender, socio economy and number of pain regions (OR 2.94; 1.48–5.82 and OR 2.65; 1.24–5.64) and in a model adjusting for age, gender, socio economy and pain severity (OR 2.97;1.53–5.76; and OR 3.02;1.47–6.21) for the 5 year and 18 year follow-up respectively, compared to not reporting any of the sleep problems at baseline.Conclusions: Both sleeping problems and fatigue predicts the onset of CWP 5- and 18 years later. The results highlight the importance of the assessment of sleep quality in the clinic.

Tidskriftsartikel (refereegranskat)abstract
- Background: Approximately ten percent of the population report chronic widespread pain (CWP), the condition is more common among women than men. For most people, the pain interferes with many aspects of every-day life and implies large consequences. However, the group reporting CWP is heterogeneous and there is a need for better understanding of the different strategies used for coping with pain in every-day life.Objectives: The purpose of this study was to describe women’s experiences of how to cope with CWP.Methods: The study had a descriptive design with a qualitative content analysis approach. Individual interviews were conducted with 19 women, 31–66 of age, who had reported CWP in a survey 2016. CWP was defined according to the 1990 ACR criteria for fibromyalgia. To be considered chronic, the pain should have persisted for more than three months during the last 12 months. A manifest qualitative content analysis was used to analyze the main question “How do you cope with your chronic widespread pain?” The analysis resulted in four categories.Results: Women described their coping with CWP in four different ways; to take control, to continue as usual, to follow instructions and to rest. To take control meant to make deliberate decisions to handle everyday day life. It also meant to take care of oneself, to think positive and to exercise at an adequate level. To continue as usual meant not to listen to body signals and either to ignore or accept the pain. To follow instructions meant listening to the health professionals and following advices, but without taking any part of the responsibility for the treatment outcome. To rest meant to perceive an unreasonable need for recovery, to resign and let the pain set the terms for the daily living.Conclusions: Women expressed different ways of coping with CWP including both active and passive strategies. The coping strategies included two dimensions, where one ranged from actively taking control over the pain, to passively following instructions and the other from actively continue as usual by either accepting or ignoring the pain to passively rest and being mastered by pain.

- Aim: We previously reported that consuming milk cereal drinks at six months of age was associated with a high body mass index (BMI) at 12 and 18 months. This study examined the association between daily consumption at 12 months of age and BMI at the age of five.Methods: We followed up 1870/2666 (70%) children recruited at birth in 2007–2008 for the Swedish longitudinal population‐based Halland Health and Growth Study a mean of 5.09 ± 0.28 years. Feeding practices were obtained from parental questionnaires, and anthropometric data were collected by child health nurses.Results: At five years, 11.6% were overweight and 2.3% were obese. Milk cereal drinks were consumed by about 85% and 10% at one and five years of age, respectively. Consumption at 12 months was associated with almost double the risk of being overweight at five years of age (adjusted odds ratio 1.94, 95% confidence interval 1.08–3.50). Other risk factors were a family history of obesity, low paternal educational level and paternal smoking.Conclusion: Consuming milk cereal drinks daily at 12 months was associated with a twofold risk of being overweight at five years. These findings may affect the counselling guidelines used at child healthcare centres. Copyright © 2019 John Wiley & Sons, Inc. All rights reserved

- BACKGROUND: Breastfeeding is associated with many benefits for both mother and child. Initiation rates are high in Sweden. Recently a slight decline is seen.AIM: The aim of this study was to assess factors associated with discontinuation of breastfeeding during the first 4 weeks.METHOD: A population-based longitudinal birth cohort study recruiting from 2007 to 2008 in south-western Sweden. At the first visit to the child health centre, parents were asked to complete a questionnaire. Also, the infants' height, weight, head and waist circumference were collected. Response rate was 69.2%.RESULTS: Twenty-seven per cent of mothers had breastfeeding problems. In a multivariate analysis, there was a negative correlation between breastfeeding and use of pacifier (OR 3.72; CI 2.09-6.63), maternal smoking (OR 2.09; CI 1.08-4.05) and breastfeeding problems (OR 2.54; CI 1.73-3.71). Breastfeeding problems were correlated with poor sucking technique (OR 2.96; CI 2.14-4.07), support from maternity ward (OR 2.56; CI 2.05-3.19) and perceived poor weight gain (OR 1.37; CI 1.00-1.86).CONCLUSION: Many mothers reported breastfeeding problems that are associated with an early cessation. This is preventable with support, but the timing is crucial. To promote breastfeeding, the support from the child health centres must be tailored with the maternal perspective in mind.© 2011 Foundation Acta Pædiatrica

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Parental socioeconomic status (SES) is an important determinant in child health, influencing beneficial factors such as breastfeeding. A better understanding of the influence of neighbourhood-level SES measures, relating to spatial determinants, might lead to targeted actions to promote breastfeeding during infancy.METHODS: A cross-sectional study analysis the association between breastfeeding at four months of age and neighbourhood purchasing power, taking account of individual-level variables including maternal age, smoking and parental level of education. Data were obtained from a prospective population- based cohort study recruited from birth in 2007-2008 in the Halland region, southwestern Sweden. Questionnaire data on the individual-level variables and the outcome variable of breastfeeding at four months (yes/no) were used (n=2,407). Each mother was geo-coded with respect to her residential parish (there are 61 parishes in the region) and then stratified by parish-level household purchasing power. It emerged that four neighbourhood characteristics were reasonable to use, viz. <10%, 10-19%, 20-29% and ≥ 30% of the resident families with low purchasing power.RESULTS: The proportion of mothers not breastfeeding at four months of age showed a highly significant trend across the neighbourhood strata (p=0.00004): from 16.3% (< 10% with low purchasing power) to 29.4% (≥ 30% with low purchasing power), yielding an OR of 2.24 (95% confidence interval: 1.45-3.16). After adjusting for the individual-level variables, the corresponding OR=1.63 (1.07-2.56) was significant and the trend across the strata was still evident (p=0.05). A multi-level analysis estimated that, in the neighbourhoods with ≥ 30% of the families with low purchasing power, 20% more mothers than expected, taking account of the individual-level factors, reported no breastfeeding at four months of age (≥ 95% posterior probability of an elevated observed-to-expected ratio).CONCLUSION: The neighbourhood purchasing power provided a spatial determinant of low numbers of mothers breastfeeding at four months of age, which could be relevant to consider for targeted actions. The elevated observed-to-expected ratio in the neighbourhoods with the lowest purchasing power points toward a possible contextual influence. © 2013 Almquist-Tangen et al.; licensee BioMed Central Ltd.

- AIM: Infant feeding affects growth, obesity and life-long health. This study examined the impact of dietary patterns on body mass index (BMI) at 12 and 18 months.METHODS: We followed a cohort of 2,666 children recruited in 2007-2008. Feeding practices were obtained from parental questionnaires and anthropometric data collected by child health nurses.RESULTS: At six months, 58.3% of the infant were breastfed, but only 1.6% exclusively. Many had begun eating solids (91.8%), porridge (87.7%) or milk cereal drink (46.6%). Bottle-feeding at four months was not a risk factor for a high BMI (>1 SD) at 12 or 18 months. Milk cereal drink at six months increased the risk of a high BMI at 12 and 18 months respectively (OR 1.58, 95% CI 1.12-2.22, and 1.52, 1.07-2.17). Milk cereal drink use was increased by low parental education and maternal obesity and reduced by troubled sleep and parental group participation.CONCLUSION: Formula at four months did not predict a high BMI at 12 or 18 months. Milk cereal drink use at six months was a risk factor for a high BMI at 12 and 18 months. The choice of milk cereal drink was influenced by parental factors, especially educational levels. ©2013 Foundation Acta Pædiatrica. Published by John Wiley & Sons Ltd.

Associations Between Chronic Widespread Pain, Pressure Pain Thresholds and Leptin in Individuals with Knee Pain
- 2022

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. 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).ConclusionThe pathophysiological mechanism causing widespread pain is probably multifactorial, involving both biological and physical factors. 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.

- 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.
