Adequacy of Bristol stool formscale in the assessment of stools by mothers of healthy infants in Ibadan, Nigeria

Abstract

An important complaint of mothers is the stool form of their infants. In the evaluation of stool forms, healthcare workers usually depend on mothers’ reports which are subjective and influenced by interpretation bias by health care personnel. There is therefore the need for an objective method of describing stool forms. In the present study, we evaluated the utility of the 7-point Bristol Stool Form Scale (BSFS) when used by mothers of healthy Nigerian infants. Materials and Methods: The mothers of 122 healthy infants delivered at term, with infants less than six months of age attending the Infant Welfare Clinics of two health facilities in Ibadan, South West, Nigeria for routine immunisation were enrolled. Mothers were requested to identify their child’s most recent stool form using the 7-point BSFS. Results: The mean ± SD age of the 122 study infants was 80 ±41.6 days (range 4-180 days). Eighty- eight (72.1%) infants were exclusively breastfed and 34 (27.9%) were on mixed feeding. Almost all (120; 98.4%) mothers felt that the BSFS adequately described their infants’ stools. The most commonly reported stool types were Type 6 (56.7%) and Type 7 (33.3%). There was no association between reported stool consistency and infant feeding type, level of maternal education and number of previous babies nursed. Conclusion: This study indicated that BSFS may be a reliable tool for mothers to describe stool consistency in healthy Nigerian infants.
