**En fjärdedel av gifta kvinnor i Mogadishu saknar tillgång till moderna preventivmedel** En studie från Karolinska Institutet identifierar betydande marknadspotential: 25 procent av fertila gifta kvinnor i Mogadishu använder inte modernt preventivmedel trots önskan om att fördröja eller begränsa barnafödandet. Forskarna analyserade 462 slumpmässigt utvalda kvinnor mellan oktober 2024 och januari 2025 och använde logistisk regression för att identifiera barriärer. Analfabetism tredubblade oddset för ouppfyllt behov jämfört med högre utbildning. Kvinnor med första graviditet före 18 år hade 1,8 gånger högre odds för ouppfyllt behov. Saknad mödravård under senaste graviditet förknippades också med högre odds. Studien leds av Karolinska Institutet i samarbete med somaliska universitet. Resultaten pekar på långsiktig marknadsöppning för distributionsmodeller som kombinerar utbildning, tidig graviditetsprevention och förbättrad mödravård i låginkomstregioner.
