CRP and infection: Our specific objectives were (1) to record CRP concentrations in a population of indigenous pregnant and lactating women and (2) to assess which among a range of other inflammatory markers (platelets, neutrophils, cytokines), environmental factors (wood smoke, field work), infections (oral, urogenital, intestinal, skin), and micronutrient deficiencies (folate, vitamins A, B12 and D) were associated with CRP concentrations during pregnancy and lactation.
