The influence of westernisation on pain perception in labour among parturients at the university college hospital Ibadan.

Pain perception as perceived by the parturient is determined by physical and psychological factors. The interplay of these factors is important to the healthcare professional who will be managing these women in labour. We therefore set out to assess the influence of educational attainment as a proxy for westernisation on pain perception by parturients. This was a cross-sectional study conducted among 765 parturients using a questionnaire with the Box Numerical Scale to assess pain score within 48 h of delivery. We studied women in labour at the University College Hospital Ibadan Nigeria from August 2003 to July 2004. A total of 1,000 consecutive parturients were enrolled into the study but 765 were included in the analysis after excluding women requiring caesarean section. Multiple linear regression with robust estimation of the Standard Error of the Mean (SEM) was utilised. The main outcome studied was the pain score obtained within 48 h of delivery using the Box Numerical Scale (BNS). The pain scores were highest among ethnic groups other than the predominant ethnic group (Yoruba) 9.13 (95% CI 8.13 - 9.33), it was lowest among those with no formal education. Multivariate analysis revealed educational attainment as a significant predictor of BNS. An interaction between age and educational attainment; only women between the ages of 25 - 30 had lower mean pain scores when educated compared with those without formal education -3.56 (95% CI -4.28, -2.87). In conclusion, findings in this study support the hypothesis that westernisation through education tends to increase perception of pain by parturients in this environment.
