Abstract
OBJECTIVE: The present study investigates the association of modern health worries (MHW) with self-reported as well as general practitioner (GP)-registered non-specific physical symptoms (NSPS), medication use, alternative therapy consultations, sleep quality and quality of life. The interrelation between MHW, general environmental sensitivity and the aforementioned outcomes is also explored.
METHODS: Self-reported questionnaires and data from electronic medical records from 21 general practices in The Netherlands were combined in a sample of 5933 adult participants.
RESULTS: The majority of the participants reported increased worries about potential health effects from environmental exposures. The highest worry scores were reported by people who perceived themselves as more vulnerable to environmental stressors. After adjustment for socio-demographic characteristics and diagnosed psychiatric morbidity, higher MHW were significantly associated with increased self-reported prevalence and duration of NSPS, symptom-related healthcare utilization, GP-registered NSPS, alternative therapy consultations and lower sleep quality and quality of life. These associations were statistically mediated by perceived environmental sensitivity. No association was observed between worries and GP-registered medication prescriptions.
CONCLUSION: Modern health worries are very common in the general population. They are associated with self-reported as well as clinically defined NSPS and as such might play a key role in the process of developing and maintaining environmental sensitivities and related symptoms. A large cross-cultural longitudinal study would help to determine important aspects such as temporal precedence and stability of MHW and the relevant psychosocial context within which symptomatic conditions occur.
