“…With respect to the risk-factors literature, evidence was conflicting. In two studies [95,97], no effect of ethnicity was found, but in others, prevalence was reported to be relatively high in Caucasians [31], in women of Sephardic origin [78], or Asians [53]. Given our analysis of prevalence during pregnancy, and the fact that pregnancy-related lumbopelvic pain has been reported from many countries-in Africa [9,76,110], the Americas [27,31], Asia [35,70,104,109], Australia [16], and Europe [2,28,59,68,85,88, 100]-we propose concluding that the few cases in which a relationship was found occurred by chance, and that, actually, maternal ethnicity is not a risk factor.…”
