Background: We aimed to assess how lifestyle factors such as diet, sleep, screen viewing, and physical activity, individually, as well as in a combined score, were associated with neuropsychological development in pre-school age children. Methods: We conducted a cross-sectional study in 1650 children of 4 years of age, from the Environment and Childhood Project (INMA) population-based birth cohorts in four regions of Spain. Children were classified per a childhood healthy lifestyle score (CHLS) with a range of 0 to 4 that included eating in concordance with the Mediterranean diet (1 point); reaching recommended sleep time (1 point); watching a maximum recommended screen time (1 point); and being physically active (1 point). The McCarthy Scales of Children's Abilities (MSCA) were used to test neuropsychological development. Multi-adjusted linear regression models were created to assess the association with the lifestyle factors individually and as a combined score. Results: CHLS was not associated with MSCA general cognitive score (1-point increment = -0.5, 95% CI: -1.2, 0.2). Analyzed by separate lifestyle factors, physical activity had a significant negative association with MSCA score and less TV/screen time had a negative association with MSCA score. Conclusion: In this cross-sectional study, a combined score of lifestyle factors is not related to neuropsychological development at pre-school age. ; Sabadell: This work was supported by grants from the Spanish Ministry of Health [FIS-PI041436]; Instituto de Salud Carlos III [Red INMA G03/176 and CB06/02/0041 and predoctoral grant PFIS 2010, Register FI10/00399]; the Generalitat de Catalunya-CIRIT [1999SGR 00241]; the EU sixth framework project NEWGENERIS [FP6-2003-Food-3-A-016320]; Fundació Roger Torné, and Fundació La Mataró de TV3 (Project No. 090430 and No. 20162210).

BACKGROUND: Perfluoroalkyl substances (PFAS) may affect body mass index (BMI) and other components of cardiometabolic (CM) risk during childhood, but evidence is scarce and inconsistent. OBJECTIVES: We estimated associations between prenatal PFAS exposures and outcomes relevant to cardiometabolic risk, including a composite CM-risk score. METHODS: We measured perfluorohexanesulfonic acid (PFHxS), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) in maternal plasma (first trimester). We assessed weight gain from birth until 6 mo. At 4 and 7 y, we calculated the age- and sex-specific z-scores for BMI, waist circumference (WC), and blood pressure (BP) (n≈1,000). At age 4, we calculated the age-, sex-, and region-specific z-scores for cholesterol, triglycerides (TGs), high-density (HDL-C), and low-density lipoprotein cholesterol (LDL-C) (n=627). At age 4, we calculated a CM-risk score (n=386) as the sum of the individual age-, sex-, and region-specific z-scores for WC, BP, HDL-C, and TGs. We used the average between the negative of HDL-C z-score and TGs z-score to give similar weight to lipids and the other components in the score. A higher score indicates a higher cardiometabolic risk at age 4. RESULTS: PFOS and PFOA were the most abundant PFAS (geometric mean: 5.80 and 2.32 ng/mL, respectively). In general, prenatal PFAS concentrations were not associated with individual outcomes or the combined CM-risk score. Exceptions were positive associations between prenatal PFHxS and TGs z-score [for a doubling of exposure, β=0.11; 95% confidence interval (CI): 0.01, 0.21], and between PFNA and the CM-risk score (β=0.60; 95% CI: 0.04, 1.16). There was not clear or consistent evidence of modification by sex. CONCLUSIONS: We observed little or no evidence of associations between low prenatal PFAS exposures and outcomes related to cardiometabolic risk in a cohort of Spanish children followed from birth until 7 y. https://doi.org/10.1289/EHP1330 ; This study was funded by grants from the European Union (FP7-ENV-2011 cod 282957 and HEALTH.2010.2.4.5-1), and from Spain: Instituto de Salud Carlos III and Ministry of Health (Red INMA G03/176; CB06/02/0041; PI041436, PI081151, PI06/0867, PS09/00090, PI13/02187; FIS-FEDER: PI03/1615, PI04/1509, PI04/1112, PI04/1931, PI05/1079, PI05/1052, PI06/1213, PI07/0314, PI09/02647, PI11/01007, PI11/02591, PI11/02038, PI12/01890, PI13/1944, PI13/2032, PI14/00891, and PI14/1687; predoctoral grant PFIS - FI14/00099; and Miguel Servet-FEDER: CP11/0178 and CPII16/00051), CIBERESP; the Conselleria de Sanitat, Generalitat Valenciana; Department of Health of the Basque Government (2005111093 and 2009111069); the Provincial Government of Gipuzkoa (DFG06/004 and DFG08/001); and the Generalitat de Catalunya-CIRIT (1999SGR 00241); and from the United Stated of America: National Institute of Environmental Health Sciences of the National Institutes of Health (NIH) (grant number ES021477).

Seafood consumption during pregnancy is thought to be beneficial for child neuropsychological development, but to our knowledge no large cohort studies with high fatty fish consumption have analyzed the association by seafood subtype. We evaluated 1,892 and 1,589 mother-child pairs at the ages of 14 months and 5 years, respectively, in a population-based Spanish birth cohort established during 2004-2008. Bayley and McCarthy scales and the Childhood Asperger Syndrome Test were used to assess neuropsychological development. Results from multivariate linear regression models were adjusted for sociodemographic characteristics and further adjusted for umbilical cord blood mercury or long-chain polyunsaturated fatty acid concentrations. Overall, consumption of seafood above the recommended limit of 340 g/week was associated with 10-g/week increments in neuropsychological scores. By subtype, in addition to lean fish, consumption of large fatty fish showed a positive association; offspring of persons within the highest quantile (>238 g/week) had an adjusted increase of 2.29 points in McCarthy general cognitive score (95% confidence interval: 0.42, 4.16). Similar findings were observed for the Childhood Asperger Syndrome Test. Beta coefficients diminished 15%-30% after adjustment for mercury or long-chain polyunsaturated fatty acid concentrations. Consumption of large fatty fish during pregnancy presents moderate child neuropsychological benefits, including improvements in cognitive functioning and some protection from autism-spectrum traits. ; This study was funded by grants from the Spanish Institute of Health Carlos III (Ministry of Economy and Competitiveness) (Infancia y Medio Ambiente (INMA) Network grants G03/176 and CB06/02/0041 and Fondo de Investigación Sanitaria (FIS) grants FIS-PI041436, FIS-PI081151, FIS-PI042018, FIS-PI09/02311, FIS-PI06/0867, FIS-PS09/00090, FIS-PI03/1615, FIS-PI04/1509, FIS-PI04/1112, FIS-PI04/1931, FIS-PI05/1079, FIS-PI05/1052, FIS-PI06/1213, FIS-PI07/0314, FIS-PI09/02647, FIS-13/02429, FIS-PI13/1944, FIS-PI13/2032, and CP14/00108); the Fondo de Investigación Sanitaria-Fondo Europeo de Desarrollo Regional; the Generalitat de Catalunya-Consejo Interdepartamental de Investigación e Innovación Tecnológica (grant 1999SGR 00241); Juan de la Cierva (grant 2011-09771-MICINN); the Conselleria de Sanitat Generalitat Valenciana 1 (grants 048/2010 and 060/2010); the Universidad de Oviedo, Obra Social Cajastur, Department of Health of the Basque Government (grants 2005111093 and 2009111069); the Provincial Government of Gipuzkoa (grants DFG06/004 and DFG08/001); and the Fundación Roger Torné.
