BackgroundBreastfeeding techniques are strongly associated with the exclusive breastfeeding. It is the very key time to improve mothers’ breastfeeding techniques during staying in the hospital and delivery institution, but there is little study about in-hospital breastfeeding techniques in China. This study aimed to assess the breastfeeding techniques and its associated factors among mothers in hospital. MethodsA cross-sectional study was conducted in Peking university people’s hospital, china, from March 19, 2018 to April 27, 2018. 153 mothers selected by convenience sampling technique were investigated by questionnaire survey, which includes the LATCH scoring system, the general information and breastfeeding behavior questionnaire, the breastfeeding knowledge questionnaire, and the Chinese version of maternal breastfeeding evaluation scale (MBFES). Factors associated with in-hospital breastfeeding techniques were determined by multiple regression analysis. ResultsThe average score of breastfeeding techniques assessed before discharge was 8.63, the multipara, long hospital staying, and high breastfeeding satisfaction were positive effects to breastfeeding techniques before discharge (P<0.05), which could explain 11.2% of the variance.ConclusionAlthough the breastfeeding techniques before discharge are high, we can still make efforts to improve it. Implementing measures to promote breastfeeding, provide breastfeeding guidance right after delivery, take timely evaluation and specific guidance will be conducive to improve the breastfeeding techniques and do help to increase the exclusive breastfeeding rate.
