AimDo the clinical findings explain the complaints of longstanding demonstrated widespread pain (DWP) in a group of immigrant patients, or not?SubjectsConsecutive immigrant patients, on long-term sick leave, aged 18 - 45, at a primary healthcare centre in Stockholm, Sweden.MethodsInterpreters were available. Two primary care physicians jointly, made a somatic status and diagnosed tender-structure locations (> or =3 tender-structure locations or less) and depression (yes or no), and assessed psychosocial stressors (little or much) and pain-related anxiety (yes or no). The patients pointed at their pain parts. This was transferred by one of the doctors to a pain drawing with 18 fields. Five or more fields were defined as DWP. Non-parametric tests were used to detect significant differences between the DWP and non-DWP groups. Cumulative frequencies of the following four categories of explanatory variables of DWP were counted: > or =3 tender-structure locations (could also include the other variables), much psychosocial stress (could include depression and pain-related anxiety), depression (could include pain-related anxiety), or pain-related anxiety alone.ResultsMany of the 49 men and 100 women, on average 38 years, spoke little or no Swedish. A fifth of the men (n = 10) and half (n = 56) of the women had DWP. These men often had much stress (p < 0.01) while the women had > or =3 tender-structure locations (p < 0.001). DWP among men was explained to 100% by: > or =3 tender-structure locations (30%), much psychosocial stress (60%), or depression alone (10%). DWP among the women was explained to 96 cum. % by: > or =3 tender-structure locations (59%), much psychosocial stress (25%), or pain-related anxiety alone (13%).ConclusionDemonstrated widespread pain was nearly always explained by clinical findings, and especially by numerous tender-structure locations in women. There is a need for more studies among men.
