Effects of abdominal girdle belt on pulmonary function variables of postpartum women in Enugu, Nigeria: a quasi-experimental study.

This quasi-experimental study was aimed at investigating the effects of wearing an abdominal girdle belt on pulmonary function variables of postpartum women. 40 consenting postpartum women aged between 18 and 35 years were recruited from a post-natal clinic in Enugu, Nigeria. The participants were conveniently assigned into girdle belt and control groups (20 each). Their lung function (forced expiratory volume in first second[FEV1], and %FEV1, forced vital capacity[FVC], peak expiratory flow [PEF], forced expiratory flows [25th, 75th & 25-75th percentiles]) values were measured prior to and after eight weeks of the study intervention period for each participant. Data obtained were analysed using descriptive and inferential statistics. Following the intervention period, 19 and 13 participants completed the study in the girdle belt and control groups, respectively. The main results showed that both groups were comparable at baseline for all the study variables assessed (p > 0.05). Following the intervention period, only the PEF was significantly reduced in the girdle belt group compared to control group participants (p = 0.012). Thus, wearing girdle belts for an extended period of time has no effect on the lung function values of postpartum women.IMPACT STATEMENTWhat is already known on the subject? Postpartum abdominal girdle belts are commonly utilised for resolution of abdominal protrusion and obesity after childbirth. Unfortunately, several adverse effects, including bleeding, compressive pain and discomfort and abnormally increased intra-abdominal pressure, have been associated with this practice. Consistent increase in intra-abdominal pressure of variable duration has been reported to affect pulmonary functions.What do the results of this study add? The study findings indicate that wearing girdle belts for eight weeks by postpartum women has no substantial effect on the pulmonary function variables.What are the implications of these findings for clinical practice and/or further research? Utilisation of abdominal girdle belts of equal or less than 8 weeks duration should not be discouraged for post-partum women due to fear of its potential negative impact on pulmonary function.
