The influence of ergonomic breastfeeding training on some health parameters in infants and mothers: a randomized controlled trial

Abstract

BackgroundBreastfeeding is considered as a protective factor against non-communicable diseases in infants and mothers. The first aim of this study was to assess the influence of ergonomic breastfeeding training on the infants’ growth. The second aim was to investigate the effectiveness of this training for improving musculoskeletal disorders in mothers.MethodsIn this randomized control trial, 104 participants who were referred to the health centers in Shiraz for breastfeeding care were randomly allocated into the intervention or comparison group using a size-four block sampling method. At birth, 2, 4, and 6 months later childbirth, Rapid Upper Limb Assessment was used to assess musculoskeletal disorders in participants, and the severity of their discomfort was measured with the Visual Analog Scale. During the 6 months of the study (March to September, 2017), the weight and height of the neonates were measured every 2 months.ResultsSignificant differences were found between groups in the priority level for corrective action in mothers’ postures determined by Rapid Upper Limb Assessment at 2, 4 and 6 months after childbirth (p < 0.001). Based on the Visual Analog Scale results in mothers at 6 months after childbirth, fewer back pain was reported by the intervention group (p = 0.03). No significant difference were found in the infants’ weights and heights in boys and girls at all growing stages between the two study groups (p > 0.05). However, the mean height for age of the girl infants at age of 6 months was higher among intervention groups compared to the controls (p = 0.01).ConclusionThis study demonstrated that ergonomic breastfeeding training reduced the incidence of musculoskeletal disorders in mothers but seems not to have any significant and consistent impact on the infants’ growth.Trial registrationfa.irct.ir IRCT2014042317398N1.
