Key modifiable factors included BMI, interlinked with chronic hypertension\/elevated blood pressure in early pregnancy, type 2 diabetes mellitus, and obstructive sleep apnoea, as well as antenatal care attendance, interconnected with maternal\/work stress and prenatal micronutrient supplementation. Other modifiable factors included smoking, antiphospholipid syndrome, infection, exposure to occupational hazards, distance to health facility, maternal heat exposure in early gestation, and UV\u2010B exposure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>There are strong social factors alongside clinical factors associated with pre\u2010eclampsia incidence.
