Abstract
Introduction & Objective: Planning to improve lifestyle through training breastfeeding mothers and transferring this training to children leads to raising healthier children. The goal of this paper is to examine the effect of demographic variables on different aspects of breastfeeding mothers' health.
Method: In this quasi-experimental interventional study, 97 mothers who referred to clinics in Fasa were randomly divided into case (n = 48) and control (n = 49) groups. In order to collect data, the questionnaire of health-promoting lifestyle by Walker et al. which includes 52 questions and the questionnaire of demographic variables were applied. After the first stage of distributing the questionnaires was done, 5 class sessions of training were held for the case group. SPSS20 software and correlation coefficient test were used for analyzing the data.
Results: It was found that the highest and lowest scores, both before and after the intervention, are related to spiritual growth and interpersonal relationships; respectively. In the case group, there was a significant relationship between the income level and the spiritual growth (p value = 0.02) and in the control group, age was significantly associated with nutrition. (P value = 0.02). Various dimensions of the questionnaire were compared with education, which only in the case group, it had a significant difference with spiritual growth (p value = 0.02).
Conclusion: Demographic variables such as age, education and income unavoidably affected on various aspects of health. Of course, in the case of education and spiritual growth at the undergraduate level, this difference was significant and inverse. This issue can be due to excessive preoccupation with academic issues and sometimes people move away from spirituality due to the non-inclusion of teaching these issues in the universities of the country.
