Predictors of Disability Attributed to Symptoms of Increased Interrecti Distance in Women after Childbirth: An Observational Study.

Abstract

ObjectiveThe purpose of this study was to investigate how various physical and psychological factors are linked to disability attributed to symptoms from increased interrecti distance (IRD) in women after childbirth.MethodsIn this cross-sectional observational study, 141 women with an IRD of at least 2 finger-widths and whose youngest child was between the ages of 1 and 8 years participated. A multiple linear regression model was performed, with disability as the outcome variable and fear-avoidance beliefs, emotional distress, body mass index, lumbopelvic pain, IRD, and physical activity level as predictor variables.ResultsThe regression model accounted for 60% (R2 = 0.604, adjusted R2 = 0.586) of the variance in disability (F6,132 = 33.5). The 2 strongest predictors were lumbopelvic pain, with a regression coefficient of 1.4 (95% CI = 1.017 to 1.877), and fear avoidance, with a regression coefficient of 0.421 (95% CI = 0.287 to 0.555). The actual IRD, with a regression coefficient of −0.133 (95% CI = −1.154 to 0.888), did not contribute significantly to the variation in disability.ConclusionDisability attributed to symptoms from an increased IRD is explained primarily by the level of lumbopelvic pain but also by the degree of fear-avoidance beliefs and emotional distress.ImpactThis study highlights pain intensity and psychological factors as crucial factors for understanding disability attributed to increased IRD.
