Effectiveness of community-based intervention on improvement of pregnancy and delivery process in district 4 of Tehran

To reduce cesarean section rate, we need complex interventions to modify related behavior. We aimed to identify the effectiveness of a community-based intervention on prenatal care status, delivery and decline of cesarean section rate. A quasi-experimental study was carried out on mothers residing in Khak Sefid and Javadiyeh in Tehran from January 2011 to September 2014. Study population was 274 mothers; attending in health centers for first vaccination of their neonates. Mother's demographic data were recorded in some questionnaires. One year interventions including; consultation, distribution of educational package and training courses (for mothers, fathers and their families, educational programs for midwives, obstetricians and gynecologist, residents, medical students), accomplishment of 10 steps baby-friendly principles and provision adequate personnel in labor-delivery room were implemented in community, hospitals and health centers. After intervention, 250 mothers who were attending in health centers for vaccination of 2 months aged neonates were assessed and their data were recorded in the same questionnaires. The effectiveness of intervention on cesarean section rate and cesarean tendency in before and after intervention groups were compared. P< 0.05 was considered as level of significance. Of 274 mothers in "before intervention" group 193 (70.44%) and of 250 mothers in "after intervention", 169 subjects (67.6%) had cesarean section. Although a significant decline was seen in cesarean tendency in "after intervention" group (P= 0.034), no significant difference was seen between 2 group's cesarean section rates (P= 0.48). In "after intervention" group episiotomy, induction of labor rate and maternal morbidity were significantly lower than "before intervention" group (P= 0.0001, 0.0001, 0.01). Although no significant difference was seen between two groups neonatal birth weight (P= 0.69), a significant difference was seen between two group's gestational age (P= 0.007). After intervention, in spite of no decline in cesarean section rate, NVD tendency and morbidity rate were raised and improved respectively. It seems that cesarean section rate was influenced by other important factors.
