Excessive gestational weight gain (GWG) has been suggested as a contributing factor, but evidence in low\u2010income populations is scarce.

Data on sociodemographics, GWG, and LBP (visual analog scale, and body map) were collected.

Mean GWG was 12\u2009kg. Women with severe pain had higher absolute weight gain (14.7\u2009kg vs. 10.3\u2009kg;\n                      <jats:italic>p<\/jats:italic>\n                      = 0.028) but no significant difference in weight progression across trimesters.
