Abstract

This predictive research aims to study the power of prediction of prepregnancy body mass index, duration of the second stage of labor, use labor pain relief medication, maternal stress, time of first breastfeeding, and breastfeeding frequency on the onset of lactation in breastfeeding mothers. Pathophysiology perspective and literature review were used for the conceptual framework. The study was conducted with 83 vaginal delivery postpartum primiparous mothers aged 18 years and over at the postpartum ward of Charoenkrungpracharak Hospital. Data were collected using questionnaire and were analyzed using descriptive statistics and multiple regression.


Mean onset of lactation was 57.35 hours after delivery (SD = 20.26). Six factors together predicted 30.3% (R2 = 0.303,               p < 0.01) of the variance in the onset of lactation, but only two variables were statistically significant: breastfeeding frequency                  (β = -0.315, t = -3.080, p < 0.01), and use of labor pain relief drugs (β = 0.314, t = 3.064, p < 0.01). Therefore, in order to promote earlier onset of lactation in mothers, nurses should encourage breastfeeding every 2-3 hours (about 6 – 8 times daily), and emphasize non-pharmacological alternatives to relief labor pain.
