Low birth weight vs IQ study in Pune

Social and Environmental Assessment

Thirty per cent of the mothers had some degree of college education, whereas one per cent of the mothers were illiterate. Five per cent of the children lived in independent bungalows and the rest in lower and middle class localities. Most of the children (91 %) came from middle or lower middle class families (SES II or III). Fifty six per cent of the children lived in overcrowded houses.

A multiple linear regression analysis was done using IQ as the outcome variable and infant and socio-environmental information as predictor variable. The predictor. variables included socio-economic status, locality, spaciousness of the house, mother's education, etc., mental and motor age on}3ayley Scales at one year (available from the previous phase of the study), and chronic medical problems like seizures and asthma.

The regression analysis showed that mother's education (β coefficient 0.33373, p <0.001), spaciousness of the house (β coefficient 0.19424, p <0.020), and a mental age at one year (β coefficient 0.22959, p <0.009) had a significant impact on the 6 year IQ. Chronic medical problems had a negative impact on the 6 year IQ (β coefficient - 0.3573, P <0:020). Multiple R of the final module was 0.4354.
