Age and body mass index (BMI) could be a concern for expat insurance customers but research has also linked them to a raised risk of a person developing gestational diabetes mellitus (GDM) during pregnancy.
This was particularly noticeable among people from South Asia and black Africans, the study, which was published in BJOG: An International Journal of Obstetrics and Gynaecology, discovered.
White Europeans aged over 30 years old had a significantly greater likelihood of suffering from GDM than their younger counterparts aged between 20 and 24, with this elevation seen in black African women older than 25 and South Asians aged over 20.
Higher BMIs were also linked to increased rates of this illness among all racial groups.
"Gestational diabetes complicates three to five per cent of pregnancies," consultant in obstetrics and foetal medicine at the Academic Department of Obstetrics and Gynaecology in Chelsea and Westminster Hospital and co-author of the investigation Dr Makrina Savvidou declared.
"It is important that clinicians are aware of all the contributing factors," he added.
People with this condition should monitor their blood sugar levels carefully, maintain regular exercise and receive nutrition counselling, experts recommend.
