Using latent class analysis, we identify clusters of musculoskeletal complaints.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Forty percent reported a complaint during a 2\u2010week period; the most common being the low back, neck, shoulder, and knee, and 40% reported more than one complaint. Two latent classes were found for each of the nine primary pain sites except for the low back where three were found. For all primary pain areas, the largest class had site\u2010specific pain only, whereas the smallest class had diffuse pain covering large parts of the body. For participants with a primary musculoskeletal complaint in the spine, the highest probabilities for co\u2010complaints were at other sites in the spine. For primary complaints in the extremities, co\u2010complaints occurred most commonly at adjacent areas. One noticeable exception was a primary complaint of knee pain where co\u2010complaints were found in more remote areas as the neck and low back.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Unique clusters of musculoskeletal co\u2010complaints can be determined based on primary pain site.
