The mean age of participants was 31.3 years [95% CI: 31.1, 35.6], 59% aged 26-45 years. Most of the participants (93%) did not have academic education (Table 1). The mean difference of scores of knowledge before and after intervention was statistically significant between different age groups (P=0.015) and different levels of education (P=0.027).
