Birth weight (BW) is a critical indicator of perinatal health. Research has studied its prevalence, causes and determinants. Recent contributions showed that migrant-origin children are advantaged in perinatal health: They have higher BW and a lower risk of LBW. This has been interpreted as an extension of the healthy immigrant paradox. However, the narrow focus on LBW is insufficient, as evidence from Europe has proven that migrants are more likely than natives to experience unhealthy high birth weights, which correlate with adverse health outcomes over life. Using a birth cohort in France (Elfe), we (1) provide a systematic account of associations between migrant status and BW, (2) use the panel structure of the data to study trends over the first two years of life in the gap in weight outcomes, and (3) address differences in prenatal conditions and later lifestyles to account for observed differences between natives and migrants.

Uzito wa kuzaliwa (BW) ni kiashiria muhimu cha afya ya kuzaliwa. Utafiti umechunguza kuenea kwake, visababishi na mambo yanayoamua hali hiyo. Utafiti wa hivi karibuni unaonyesha kuwa watoto wa asili ya wahamiaji wana faida katika afya ya kuzaliwa: Wana BMI ya juu na hatari ya chini ya LBW. Hii imefafanuliwa kama upanuzi wa paradox ya wahamiaji wenye afya. Hata hivyo, lengo la nyembamba juu ya LBW ni haitoshi, kama ushahidi kutoka Ulaya umeonyesha kwamba wahamiaji ni uwezekano mkubwa kuliko wenyeji wa uzoefu unhealthy uzito wa kuzaliwa, ambayo inahusiana na matokeo mabaya ya afya katika maisha. Kwa kutumia kundi la kuzaliwa nchini Ufaransa (ELF), tunatoa (1) akaunti ya utaratibu wa ushirika kati ya hali ya uhamiaji na BMI, (2) kutumia muundo wa jopo la data kujifunza mwenendo katika miaka miwili ya kwanza ya maisha katika tofauti katika matokeo ya uzito, na (3) kushughulikia tofauti katika hali ya kabla ya kuzaliwa na baadaye ya maisha ili kuelezea tofauti zilizogunduliwa kati ya wenyeji na wahamiaji.
