Objective: To examine the association between household socio-economic status (SES) at birth and poor infant growth such as small for gestational age (SGA) and stunting across two different socio-cultural settings: South Africa and the Philippines. Design: Data were from two longitudinal birth cohorts, the Birth to Twenty (Bt20) study in South Africa and the Cebu Longitudinal Health and Nutrition Survey (CLHNS) in the Philippines. Subjects: Bt20 infants (n 2293 total; reduced to 758 (SGA), 450 (stunting 1 year) and 401 (stunting 2 years)) and CLHNS infants (n 2513 total; reduced to 2161 (SGA), 1820 (stunting 1 year) and 1710 (stunting 2 years)). Results: CLHNS infants were significantly more likely to be born SGA (20.9 v. 11.7%) and be stunted at 1 year (32.6 v. 8.7%) and 2 years (48.9 v. 21.1%) compared with Bt20 infants. Logistic regression analyses showed that SES (index) was a significant predictor of stunting at 1 and 2 years of age in the CLHNS cohort. SES (index or individual variables) was not a significant predictor of SGA in either cohort, or of stunting in the Bt20 cohort. Maternal education, ownership of a television and toilet facilities were all independent predictors of stunting in the CLHNS cohort. Conclusions: The social and economic milieu within the Philippines appears to place CLHNS infants at greater risk of being born SGA and being stunted compared with Bt20 infants. The present research highlights the importance of investigating the individual SES variables that predict infantile growth faltering, to identify the key areas for context-specific policy development and intervention.
