Strengths and limitations
This was the first controlled evaluation of gANC in Sweden attempting to address the particular needs of migrant women, with a participatory approach. This is of particular importance in groups of women who are often excluded in research, are hard to reach or when studying sensitive health issues.For this study, women were recruited from one site only, and the possible selection bias of participants recruited to the study further limits the generalisability of the results. We do not know if the results are representative for similar Somali-Swedish groups of women. The findings can however inform future randomised controlled trials and be useful for future power calculations.
