Relación en España de la duración de la gestación y del peso al nacer con la nacionalidad de la madre durante el período 2001-2005

Abstract

Results of LBW and PB were more favourable in the births of immigrant women. It could be associated with the healthy migrant effect and a low frequency of risk practices during gestation.

Too heavy, too late: investigating perinatal health outcomes in immigrants residing in Spain. A cross-sectional study (2009–2011)

“…All groups show a lower risk of LBW with the exceptions of EU-15 and USA & Canada, with no conclusive differences, and sub-Saharan Africa, who show a significantly higher risk. These results support previous evidence in Spain for most groups29 30 and a disadvantage for babies of sub-Saharan descent 30 31. The advantage is also observed among LBW at term babies (proxy of babies with intrauterine growth restriction).…”

“…For gestational age, however, we find a higher risk of preterm birth for groups who had shown advantages in earlier studies (period before 2006),30 31 such as South America, the Caribbean and EU-Extension. The pattern we observe seems consistent over very (<32 gestational weeks) and moderate preterm (>32 gestational weeks and <37 gestational weeks) (data not shown in tables).…”

“…Research on preterm birth and LBW has pointed out that selection in origin and cultural values that discourage women from engaging in negative health behaviours may compensate for, and even counterbalance, the risks associated with belonging to a socioeconomically disadvantaged group 30 32. However, the absence of this advantage on the other side of the distribution may suggest the possibility that immigrants and Spaniards are affected by different sets of risk factors, creating different populations at risk at birth (LBW vs macrosomic and preterm vs post-term).…”

Association between periodontal status and pre‐term and/or low‐birth weight in Spain: clinical and microbiological parameters

“… reported a significant association between the presence of periodontal disease and PTB, with an adjusted OR of 1.77. Again in this study the population assayed was different, since it included only a 78% of Caucasian women and mainly of low social, economic and educational level, reporting a prevalence of PTB of 6.6%, higher than in our study, but more similar to the epidemiological figures reported for the general population in Spain (7.9% in 2001–2005) . Moreu et al .…”

Perinatal outcomes among immigrant mothers over two periods in a region of central Italy

“…Infants born to immigrant women in the US, Belgium, and France had lower risks of low birth weight compared to the native-born population [22,23]. In a Spanish study immigrant infants showed lower risks of low birth weight and prematurity compared to those of native-born women [24]. Such contrasting evidence may be explained by different access and referral to healthcare services [8,13,25], and by different integration policies in the host countries [11].…”
