Abstract:Objective To explore the effect of family participation health education on the subjective well-being of primipara and breastfeeding efficacy. Methods From April 2017 to March 2018, a total of 108 cases of primiparous women who were expected to give birth in the Nanjing Lishui People’s Hospital were selected, while they were divided into observation group of 55 cases and control group of 53 cases by random number table method. The control group was given regular health education, and the observation group was combined with family-participatory health education on the basis of the control group. Followed up for three months, the subjective well-being, breastfeeding efficacy and breastfeeding behavior of the two groups were compared. Results Follow-up for three months, the total scores for health worry, energy, melancholy and happy mood, relaxation and tension, and subjective well-being of the observation group were significantly higher than those of the control group, and the differences were statistically significant (P < 0.05). After three months of follow-up, there was no statistically significant difference in the depression and happiness scores between the control group and the same group before education (P > 0.05). Other subjective well-being scores were higher than those of the same group before education, and the differences were statistically significant (P < 0.05). After three months of follow-up, the subjective well-being scores of the observation group were higher than those before education, and the differences were statistically significant (P < 0.05). After three months of follow-up, the total scores of breastfeeding skills, inner activity and breastfeeding self-efficacy scale in the two groups were higher than those before education, while those of the observation group were higher than those of the control group, and the differences were statistically significant (P < 0.05). The breastfeeding behavior of primiparas in the two groups was significantly different, and the difference was statistically significant (P < 0.05). Conclusion Family participatory health education helps to enhance the subjective well-being of primiparas, promote the development of breastfeeding efficiency, and increase the rate of breastfeeding behavior.
