Research abstract:<\/strong><\/h3>\n

Background:
\nChronic fatigue syndrome (CFS) is a prevalent and debilitating symptom\u00a0complex of unknown aetiology. Up to 96.8% of people with CFS report\u00a0unrefreshing sleep and many describe, in qualitative interviews, changes\u00a0in sleep over the course of their illness.<\/p>\n

Purpose:
\nTo establish whether subjective and objective sleep parameters change over a two-year follow-up period in patients with CFS.<\/p>\n

Methods
\nTwenty-two participants with CFS were recruited during routine consultations at a clinic in the North-East of England. All had their sleep characterised in a previously published cross-sectional study. Two were excluded from this analysis because they fulfilled criteria for a primary sleep disorder. The remaining 20 were contacted and 15 repeated fatigue- and sleep-quality questionnaires and sleep diaries, two years after their sleep was first characterised. Seven participants also repeated two consecutive nights of polysomnography<\/a>. Paired statistical tests were used to compare follow-up with baseline measures.<\/p>\n

Results:
\nSubjective questionnaires and sleep dairies did not show differences over two years follow-up. However, polysomnography demonstrated a higher proportion of stage one sleep<\/a> (P\u2009<\u2009.01) and more awakenings per hour (P\u2009=\u2009.04) at follow-up.<\/p>\n

Conclusions:
\nThis study is the first to longitudinally assess sleep parameters in people with CFS. The results suggest that subjective perceptions of sleep remain stable, although objective measures indicated a tendency towards increased periods of lighter sleep. However, the small number of participants increases the likelihood that observed differences are Type
\nI errors.<\/p>\n
