Objective: This literature review set out to explore the impact of obesity on pregnancy outcomes in relation to an increased rate of caesarean section (CS). Methods: A systematic search strategy, utilising the Patient/Problem, Intervention, Comparison and Outcome (PICO) methodology was used. Two electronic databases, CINAHL and Medline, were searched to source relevant papers published between the years 2000 and 2011. The search identified 170 papers from CINAHL and 137 papers from Medline using the following inclusion criteria: 'written in English' and 'published between 2000 and 2011'. This led to the identification of four papers that met inclusion criteria and were the most relevant to the research question. Findings: There is evidence of an association between elevated body mass index (BMI) levels and the subsequent risk of CS. As the BMI of the woman increases from obese to morbidly obese, the likelihood of CS as an emergency procedure becomes greater. This finding was recorded in all four of the studies reviewed where higher rates of CS were found in overweight women. A 27.8% CS rate was found among obese women, compared to 10.8% among non-obese women (OR = 3.2; [95% CI 2.9, 3.5]; P

Implications: The appropriate management of the reduction in obesity levels among pregnant women is an important factor that can contribute to reduced CS..
