Methods
  • Cross sectional study.
  • Data were provided from the National Statistical
    Bulletin of Birth of 1,878,618 newborns in the
    period 2001-2005.
  • Exposure variable Mother nationality
    Spanish-Immigrant and in categories Spain,
    Southern Europe, rest of Western countries (rest
    of countries in Western Europe, United States and
    Canada), Eastern Europe, North Africa,
    Sub-Saharan Africa, Central America and,
    Caribbean, South America, Asia and Oceania.
  • Outcomes LBW (borns lt2,500 gr with
    lt37gestational weeks) and PB (lt37 gestational
    weeks).
  • Rest of variables Sex of newborn, maternal age,
    number of live born children, marital status,
    birth number, normality of birth, newborn sex
  • Descriptive analysis, prevalence of LBW and PB
    and crude and adjusted OR by logistic regression
