Abstract

Objective: To describe serum levels of calcium, copper, selenium, magnesium, iron and zinc and evaluate their relationship with maternal socio-demographic characteristics and dietary variables in women in the first trimester of pregnancy. Method: Cross-sectional study with 1279 participants from the INMA cohorts. Results: The concentrations of the elements analyzed were within the normal range. Associations with higher levels of these metals were found for calcium with white meat intake (p = 0.026), for cop-per with excess body weight (p < 0.01), low social class (p = 0.03) and being multipara (p < 0.01), for magnesium with being over 35 years old (p = 0.001), high social class (p = 0.044), primiparous status (p = 0.002) and low daily intake of bread (p = 0.009) and legumes (p = 0.020); for zinc with university edu-cation (p = 0.039) and residence in Gipuzkoa (p < 0.01), and for selenium with residence in Valencia (p < 0.01), university education (p = 0.001), vitamin B6 supplementation (p = 0.006), fish intake (> 71 g/day) (p = 0.014) and having been born in Spain (p = 0.001). Further, lower iron levels were associated with being overweight (p = 0.021) or obese (p < 0.001) and vitamin B12 supplementation (p = 0.006). Conclusions: Our results suggest that trace elements in the analyzed cohorts are adequate for this stage of pregnancy. The variability in these elements is mainly linked to socio-demographic and anthropometric variables. This study is part of the INMA (Infancia y Medio Ambiente) project. It was supported by grants from Instituto de Salud Carlos III (FIS-FEDER: 06/0867, 09/00090, 13/1944, 16/1288, 19/1338; Miguel Servet-FEDER: CP15/0025; Miguel Servet-FSE: MS15/0025) , by the Council of Gipuzkoa (DFG15/009) and by the Health Department of the Basque Government.
