Videre undersøkte man forekomsten av skiftarbeidslidelse og hvorvidt det foreligger ulikhet med hensyn til restless legs syndrom/Willis-Ekbom sykdom hos de med og uten denne lidelsen. Den totale forekomsten av restless legs syndrom/Willis-Ekbom sykdom i utvalget var 26,8 % (n = 470). Det var ingen signifikante forskjeller med hensyn til forekomst av restless legs syndrom/Willis-Ekbom sykdom når man sammenlignet forekomsten mellom de ulike typene turnus. Sykepleierne som ble klassifisert til å ha skiftarbeidslidelse (n = 532), hadde høyere forekomst av restless legs syndrome/Willis-Ekbom sykdom, sammenlignet med de uten denne lidelsen.
Restless Legs Syndrome/Willis-Ekbom Disease Is Prevalent in Working Nurses, but Seems Not to Be Associated with Shift Work Schedules

Insomnia and excessive sleepiness are among the most commonly reported
sleep problems related to shift work. Sleep-related movement disorders have,
however, received far less attention in relation to such work schedules. The
objective of this study was to investigate the association between different
shift work schedules and the prevalence of Restless legs syndrome/Willis-Ekbom
disease (RLS/WED) in a large sample of Norwegian nurses.
Our hypothesis was
that shift working nurses would report higher prevalence of RLS/WED compared to
day workers. A total of 1,788 nurses with different work schedules (day work,
two-shift rotation, night work, three shift rotation) participated in a cohort
study, started in 2008/2009. Four questions about RLS/WED based on the
diagnostic criteria were included in wave 4 (2012). RLS/WED prevalence rates
across different shift schedules were explored by the Pearson chi-square test.
Logistic regression analysis was used to assess the association between RLS/WED
and work schedules and shift work disorder (SWD) with adjustment for sex, age,
marital status, smoking, and caffeine use. In total, 90.0% of the nurses were
females, mean age 36.5 years (SD = 8.6, range 25-67). The overall prevalence of
RLS/WED was 26.8%.
We found no significant differences between the prevalence
of RLS/WED across the different shift schedules, ranging from 23.3% (day work)
to 29.4% (night work). There was a significant difference (p < 0.001)
in the prevalence of RLS/WED between nurses having SWD (33.5%) compared to
nurses not having SWD (23.8%). SWD remained significantly associated with
RLS/WED in the adjusted logistic regression analysis (1.56, CI: 1.24-1.97).
This study did not support the hypothesis. RLS/WED was associated with SWD,
which might indicate that nurses vulnerable to shift work also are sensitive to
other complaints related to a misalignment of the biological clock.
