International migration and gestational diabetes mellitus: a systematic review of the literature and meta‐analysis

Abstract

Influxes of migrant women of childbearing age to receiving countries have made their perinatal health status a key priority for many governments. The international research collaboration Reproductive Outcomes And Migration (ROAM) reviewed published studies to assess whether migrants in countries of resettlement have a greater risk of gestational diabetes mellitus (GDM) than women in receiving countries. A systematic review of the literature from Medline, Embase, PsychInfo and CINAHL from 1990 to 2009 included studies of migrant women and GDM. Studies were excluded if there was no cross-border movement or comparison group or if the receiving country was not the country of resettlement. Studies were assessed for quality, analysed descriptively and meta-analysed. Twenty-four reports (representing >120,000 migrants) met our inclusion criteria. Migrants were described primarily by geographic origin; other relevant aspects (e.g. time in country, language fluency) were rarely studied. Migrants' results for GDM were worse than those for receiving-country women in 79% of all studies. Meta-analyses showed that, compared with receiving-country women, Caribbean, African, European and Northern European women were at greater risk of GDM, while North Africans and North Americans had risks similar to receiving-country women. Although results of the 31 comparisons of Asians, East Africans or non-Australian Oceanians were too heterogeneous to provide a single GDM risk estimate for migrant women, only one comparison was below the receiving-country comparison group, all others presented a higher risk estimate. The majority of women migrants to resettlement countries are at greater risk for GDM than women resident in receiving countries. Research using clear, specific migrant definitions, adjusting for relevant risk factors and including other aspects of migration experiences is needed to confirm and understand these findings.

International migration and caesarean birth: a systematic review and meta-analysis

“…There were no studies identified examining determinants of caesareans in migrants specifically. However, gestational diabetes mellitus (GDM) and feto-pelvic disproportion are known to complicate delivery and increase the risk of caesarean [104,105] and these are more common in some migrant women [28,39,106]. Reasons for increased risk of GDM in migrants are unknown but might be associated with a genetic pre-disposition, or physiological response to dietary changes; the involvement of a stress response has also been proposed.…”

Disparities in Access to Prenatal Care Services for African Immigrant Women in Spain

“…Gestational diabetes screening was carried out only in 80.8 % of the AIW compared with 99.4 % of native-born mothers. As evidenced in a recent meta-analysis, immigrant women from Africa are more likely to develop gestational diabetes mellitus than their native-born peers [9]. Gestational diabetes mellitus is also a known risk factor in delivering macrosomic newborns [48,49].…”

“…It is estimated that more than half of female immigrants are of reproductive age, which means that many of their social and health needs concern reproduction and maternity [5][6][7][8][9].…”

Women’s experiences of factors that facilitate or inhibit gestational diabetes self-management

“…This figure represents approximately 4.5-5.0% of all births, although specific groups are at greater risk of developing this disorder [1]. GDM rates have increased dramatically in the past twenty years [2-4] and this pattern of increase appears to relate primarily to the obesity epidemic [5], increasing maternal age [4,6], and migration from high risk areas, such as South East Asia [7]. In Australia, highest rates of GDM are reported among women born in Polynesia, Asia, South Asia (Indian subcontinent) and the Middle East.…”
