Background: Although the theoretical impact of small in weight and/or size at birth (<2 SDS for EG) is 3–5% (3.5% in the Basque Country (source: Local Government) the socio-economic situation in our country has conditioned a change in its l although 50% at 2 years did not do a proper catch up (by excess or defect) with potential impact on future size and metabolic complications, cardiovascular require specific monitoring.

Objective: To assess socio-epidemiological changes of the new born in our country in the past 10 years and its influence on the SGA pathology.

Material and methods: Study and classification of 4934 cases (♂ 2485) live and single pregnant in our hospital (years 2004–2005) (G1) and weight/height tables regarding Spanish reference (2008) according to age, sex, and weight/height compared to 5942 cases (♂ 3066) live singletons in our hospital (years 2011–2012) (G2). SGA if <2 SDS weight and/or size (balance accuracy and normalized stadiometer). Student’s t study bilateral IBM SPSS 18.0. Total: 10 876 cases studied.

Results: G1 total SGA 319 (6.4% of total) (♂ 140, 43%). G2 total SGA 438 (7.4% of total) (194 ♂, 44%) increased 2.7% P: 0.01. In G1 ♂ 5.6% are SGA and 7.3% from G2 ♀ ♂ 6.3% is 8.6% SGA and ♀ Δ P: 0.02. Regarding maternal age distribution of RN is almost similar in both groups: G1 parity 25–29a (14%), 30–34a (38%), 35–39a (33%) average 31.8 years vs G2 parity 25–29a (15%), 30–34a (40%), 35–39a (31%) average 32.5 years ΔP: 0.06. PEG proprocional are distributed. About groups: G1 preterm newborns (<37s) represent 493 (10%), with 30 SGA (6%). G2 preterm infants (<37s) account 416 (7%), with 20 PEG (5%). ΔP: 0.01. Regarding parity: primiparous assume G1 2220 (45%) with SGA 255 (8.7%) (80% f total). G2 represent primiparous 2495 (42%), SGA 261 (10.5%) (60% of total). ΔP: 0.01. Regards, on 222 G1 mothers were foreign (4.5%) compared to 1366 G2 mothers were foreign (23%) ΔP: 0.001. Facing the Spanish their mean age was 26.2 vs lower 34th, the most parity 2.8 vs 1.6% and the lower the PEG (4.8 vs 8.2).

Conclusions: Our media has seen an increasing number of children born SGA, especially in Spanish, primiparous and more elderly women. Global strategy is necessary.
