This predictive study aimed to examine predicting factors of successfulness in exclusive breastfeeding for the first six months among working mothers. The participants included three hundred and thirty-two working mothers who brought their babies to the well-baby clinic for a follow-up at a public hospital in Bangkok, Thailand. Data were collected using the survey forms for demographic information, breastfeeding self-efficacy, family support, nurse support, workplace support, and successfulness in exclusive breastfeeding form, with content validity index yields .97, .95, .96, .96, and 1.00, respectively and reliability yields .85, .89, .84, .86, and 0.88, respectively. The data were analyzed using descriptive statistics: percentage, mean, standard deviation, and logistic regression.
The results revealed that exclusive breastfeeding rate decreased from 66.6% before discharge from hospital to 18.4% within 6-month period. Logistic regression revealed that breastfeeding self-efficacy, family support, nurse support, and workplace support could explain 36% of variance (R2= .36, p< .05) in 6-month-exclusive breastfeeding of the working mothers. However, only breastfeeding self-efficacy and workplace support were significant predictors (OR=4.81; 95% CI: 2.76-8.39) and (OR=3.85; 95% CI: 1.45-10.23), respectively. Therefore, breastfeeding self-efficacy and workplace support should be considered as necessary and beneficial to achieve 6-month-exclusive breastfeeding among working mothers.
