Characteristics of the study participants of the longitudinal study at follow-up (baseline data are presented in Mohler et al. 2010 [24]) and of the participants of the nested sleep study.
Table 5.
Exposure ranges of the longitudinal study for all study participants (n = 955): ranges in power flux densities to different exposure sources for all included study participants at follow-up survey and the change in exposure levels between baseline and follow-up.
Figure 1.
Results of the longitudinal analysis on daytime sleepiness score: Diamonds refer to the change in sleep score and the horizontal lines mark the 95% confidence intervals.
An increase in score refers to an increase in daytime sleepiness. * indicates statistical significance. All models are adjusted for age, body mass index, stress level, physical activity, noise annoyance (all linear), sex, alcohol consumption, belief in health effects due to RF-EMF exposure, smoking status, degree of urbanity, moving house between the two surveys (all binary), educational level, marital status (categorical). a) for a subsample of 363 (225) subjects who consented that we receive data from the operator at baseline (follow-up). b) In the change analysis a decrease and increase in exposure refers to the participants with the 20% largest exposure decrease and increase between baseline and follow-up survey. No relevant change includes all other participants, who experienced a smaller or no change of exposure (reference group).
Figure 2.
Results of the longitudinal analysis sleep disturbances: Diamonds refer to the change in sleep score and the horizontal lines mark the 95% confidence intervals.
An increase in score refers to an increase in sleep disturbances. * indicates statistical significance. Confounders see Fig. 1. a) for a subsample of 378 (235) subjects who consented that we receive data from the operator at baseline (follow-up). b) In the change analysis a decrease and increase in exposure refers to the participants with the 20% largest exposure decrease and increase between baseline and follow-up survey. No relevant change includes all other participants, who experienced a smaller or no change of exposure (reference group).
