Abstract [en]

Building-related symptoms (BRS) is a significant work-related and public health problem, characterized by non-specific symptoms occurring in a particular building. The cause of BRS is unknown, but certain reactive compounds are suggested risk factors. The aim of this controlled exposure study was to investigate whether BRS cases report more odor annoyance and symptoms and show altered autonomous nervous system (ANS) response during exposure to the reactive aldehyde, acrolein in comparison with referents. Individuals with BRS (n = 18) and referents (n = 14) took part in two exposure sessions (80 min). One session contained heptane alone, and the other heptane and acrolein. Perceived odor annoyance; eye, nose, and throat symptoms; and ANS response were measured continuously. BRS cases did not experience more odor annoyance; eye, nose, and throat symptoms; or altered ANS response in comparison with referents during the exposures. Supplementary analyses revealed that BRS cases that also reported chemical intolerance perceived more symptoms than referents during acrolein exposure. Acrolein exposure at a concentration below previously reported sensory irritation detection thresholds is perceived as more irritating by a subgroup of BRS individuals compared with referents. The results of this study indicate that a subset of individuals with building related symptoms (BRS) has a lowered sensory irritation threshold towards acrolein exposure. Future guidelines on chemical exposures to acrolein should take time and individual sensitivity into account.

Abstract [en]

Health problems evoked in the presence of electrical equipment is a concern, calling for better understanding for characteristics of electromagnetic hypersensitivity (EHS) in the general population. The present study investigated demographics, lifestyle factors, frequency and duration, coping strategies, proportion meeting clinical criteria for intolerance attributed to electromagnetic fields (EMF) and comorbidity. Using data from a large-scale population-based questionnaire study, we investigated persons with self-reported (n=91) EHS in comparison to referents (n=3,250). Middle age, female sex and poor perceived health was found to be associated with EHS. More than 50% in the EHS group reported having EMF-related symptoms more often than once a week, and the mean number of years experiencing EHS was 10.5. More than half of the EHS group reported that their symptoms started after a high-dose or long-term EMF exposure, that they actively tried to avoid EMF sources and that they mostly could affect the EMF environment. A minority of the EHS group had sought medical attention, been diagnosed by a physician or received treatment. Exhaustion syndrome, anxiety disorder, back/joint/muscle disorder, depression, functional somatic syndrome and migraine were comorbid with EHS. The results provide ground for future study of these characteristic features being risk factors for development of EHS and or consequences of EHS.

Abstract [en]

This study tested the hypotheses of irritable bowel syndrome showing (1) comorbidity with chemical and sound intolerance, other types of functionally somatic syndromes, and psychiatric disorders and (2) stronger than normal affective reactions to and behavioral disruptions from odorous/pungent chemicals and sounds in daily life. These hypotheses were tested by means of data from a large-scale population-based questionnaire study. The results showed comorbidity in irritable bowel syndrome with chemical and sound intolerance, fibromyalgia, migraine, post-traumatic stress disorder, generalized anxiety disorder, panic syndrome, and depression as well as strong reactions/disruptions from odorous/pungent chemicals and sounds in irritable bowel syndrome.

Abstract [en]

Background: Individuals with environmental intolerance (EI) react to exposure from different environmental sources at levels tolerated by most people and that are below established toxicological and hazardous thresholds. The main aim of this study was to determine the prevalence of attributing symptoms to chemical and physical sources in the environment among individuals with different forms of self-reported EI and in referents.

Methods: Cross-sectional data from a population-based study, the Västerbotten Environmental Health Study (n = 3406), were used and individuals with self-reported EI to chemicals, buildings, electromagnetic fields and sounds as well as a group with multiple EIs were identified. The Environmental-Symptom Attribution Scale was used to quantify degree to which health symptoms are attributed to 40 specific environmental exposures and sources, with subscales referring to the four types of EI.

Results: All EI groups, except the group with building related intolerance (BRI), reported more symptoms from the expected sources compared to the referents. In addition, individuals with chemical and sound intolerance reported symptoms from building related trigger factors, and individuals with electromagnetic hypersensitivity reported symptoms from chemical trigger factors.

Conclusions: The study suggests that individuals with BRI react to fewer and more specific trigger factors than do individuals with other EIs, and that it is important to ask about different sources since three of the EI groups attribute their symptoms to a wide variety of sources in addition to the sources to which their EI implicates.

Abstract [en]

Objective: To determine the prevalence of various environmental intolerances (EIs), using several criteria in a Swedish and a Finnish general population. Ill-health attributed to low-level environmental exposures is a commonly encountered challenge in occupational and environmental medicine. Methods: In population-based questionnaire surveys, the Vasterbotten Environmental Health Study (Sweden) and the Osterbotten Environmental Health Study (Finland), EI was inquired by one-item questions on symptom attribution to chemicals, certain buildings, or electromagnetic fields (EMFs), and difficulties tolerating sounds. The respondents were asked whether they react with central nervous system (CNS) symptoms or have a physician-diagnosed EI attributed to the corresponding exposures. Prevalence rates were determined for different age and sex groups and the Swedish and Finnish samples in general. Results: In the Swedish sample (n = 3406), 12.2% had self-reported intolerance to chemicals, 4.8% to certain buildings, 2.7% to EMFs, and 9.2% to sounds. The prevalence rates for the Finnish sample (n = 1535) were 15.2%, 7.2%, 1.6%, and 5.4%, respectively, differing statistically significantly from the Swedish. EI to chemicals and certain buildings was more prevalent in Finland, while EI to EMFs and sounds more prevalent in Sweden. The prevalence rates for EI with CNS-symptoms were lower and physician-diagnosed EIs considerably lower than self-reported EIs. Women reported EI more often than men and the young (18-39 years) to a lesser degree than middle-aged and elderly. Conclusions: The findings reflect the heterogeneous nature of EI. The differences in EI prevalence between the countries might reflect disparities concerning which exposures people perceive harmful and focus their attention to.

Abstract [en]

Objectives: We tested the hypothesis of high comorbidity between asthma/allergy and chemical intolerance (CI) and between asthma/allergy and building intolerance (BI), and high multimorbidity between asthma/allergy, CI, and BI.

Methods: Population-based questionnaire data were used from 530 participants with asthma/allergy (allergic asthma, nonallergic asthma, allergic rhinitis, and/or atopic dermatitis), 414 with self-reported and 112 with physician-diagnosed CI, and 165 with self-reported and 47 with physician-diagnosed BI. Separate reference groups were formed for each of the five case groups.

Results: Adjusted odds ratios varied from 4.6 to 13.1 for comorbidity, and from 6.6 to 46.4 for multimorbidity.

Conclusion: The large comorbidity and multimorbidity between asthma/allergy, CI, and BI evokes the question as to whether there are similarities in underlying mechanisms between these conditions.

Abstract [en]

Environmental intolerance (EI) is an embracing term for a number of conditions characterized by a wide range of non-specific symptoms attributed to certain environmental exposures (e.g. pungent/odorous chemicals, residing in a certain building, electromagnetic fields and everyday sounds). EI often leads to lifestyle alterations (e.g. not taking part of activities formerly engaged in) and functional impairment (e.g. not being able to work, social deprivation). The etiology of the conditions is largely unknown, though there is growing empirical evidence for associations between mental ill-health and EI. However, mainly cross-sectional studies have been conducted which cannot demonstrate temporality. Further on, the prognosis for EI is not well-known.

This thesis includes four studies based on cross-sectional (Study 1) and longitudinal (Study 2-4) data from the Västerbotten Environmental Health Study (VEHS). The VEHS contains data from three data collections performed on the same set of respondents in 2010 (T1; n=3406), 2013 (T2; n=2336) and 2016 (T3; n=1837). In Study 1 the co-prevalence between EI attributed to chemicals, certain buildings, EMFs and sounds was investigated. The co-prevalence between all types of self-reported EI was greater than predictions based on coincidence, indicating that the different types of EI are associated, possibly sharing the same pathogenesis or that the afflicted individuals share some common predisposition to acquire the conditions. In Study 2 coping strategies and social support in EI were investigated and particularly whether certain combinations of different types of coping and social support may be important in recovering from EI. The participants who recovered from EI showed different combinations of coping strategies and social support than those who did not recover. In Study 3 the temporality between EI (attributed to chemicals, buildings and sounds) and psychological factors was investigated. The results showed that stress, anxiety, depression and burnout are risk factors for EI attributed to chemicals and sounds, but not for EI attributed to buildings. Changing perspective, EI attributed to buildings was a significant predictor of burnout, whereas EI attributed to sounds and chemicals were not. In Study 4 the prognosis of EI during a six-year period was studied. The probability of recovering from a state of specific EI was 44.3%, the probability of a specific EI to spread to other types of EI was 12.8%, and the probability of relapse was 3.9%. The participants who recovered showed lower levels of emotional and behavioral disruption than those who did not recover. The participants who showed spreading from one to several EIs perceived more stress than those who remained in a state of a specific EI, but had lower levels of burnout.

Based on the findings of the studies in the thesis it is suggested that psychotherapy focusing on reducing the emotional and behavioral reactions of exposure might be helpful. Even though the causation of EI is unknown, negative expectations about exposure might accumulate symptoms, setting a vicious circle into motion. The task of the psychologist might be to break this circle.

Abstract [en]

The modern health worries (MHW) scale was developed to assess individuals' worries about aspects of modernity and technology affecting personal health. The aim of this study was to psychometrically evaluate a Swedish version of the MHW scale and to provide Swedish normative data. Data were collected as part of the Vasterbotten Environmental Health Study, which has a random sample of 3406 Swedish adults (18-79 years). The Swedish version of the MHW scale showed excellent internal consistency and satisfactory convergent validity. A four-factor structure consistent with the original version was confirmed. The model showed invariance across age and sex. A slightly positively skewed and platykurtic distribution was found. Normative data for the general population and for combinations of specific age groups (young, middle aged, and elderly) and sex are presented. The psychometric properties of the Swedish version of the MHW scale suggest that use of this instrument is appropriate for assessing worries about modernity in Swedish-speaking and similar populations. The scale now has the advantage of good normative data being available. MHW may hold importance for understanding and predicting the development of functional disorders, such as idiopathic environmental intolerance and other medically unexplained conditions.

Abstract [en]

Chemical intolerance is a long-standing illness with minimal guidelines regarding treatment. Hence, individual attempts to cope with the illness gain importance in dealing with its consequences. This study used data from 164 persons with self-reported chemical intolerance to understand the nature of coping with the illness. Coping was studied along two dimensions, the extent and predominant orientation of coping. The association of these coping dimensions with mental health variables of stress, depression, anxiety, burnout, and non-restorative sleep was examined as well. Results revealed that the persons with chemical intolerance used a moderate amount of coping strategies which were slightly more emotion-focused than problem-focused in orientation. Users of both problem-focused and emotion-focused orientations report scores in the normal range on all mental health indices. However, significantly higher level of anxiety was found to be associated with predominantly emotion-focused coping, whereas coping orientation did not differ with respect to the four other mental health indices. The above findings are discussed in relation to existing literature on coping with long-term illness.
