Objective: To estimate the causal effect of breastfeeding on children's cognitive skills as measured at ages 3, 5, 7 and 11. Design: An instrumental variable (IV) strategy which provides a correction method for dealing with selection bias. Standard linear regression models are compared to...

Using the nationally representative Slan dataset of 2007 we analyse the relationship between self-reported and measured BMI. We find that selfreported BMI significantly underestimates obesity rates and suggest that the traditional threshold of 30 should be adjusted downwards. We outline a number...

This paper examines developments in childhood and adolescent obesity in Ireland using two waves of the Growing Up in Ireland survey. Obesity appears to level off between the two waves though there is tentative evidence that the socioeconomic gradient, measured with respect to maternal education...

This paper analyses the socioeconomic gradient of chilidhood obesity in Ireland using the Growing Up in Ireland data with three innovations compared to previous work in the area. A different measure of socioeconomic status, maternal education, is employed. In addition, the depth and severity of...

This paper examines mobility and changes in Body Mass Index (BMI) for a sample of Irish children across three waves of the longitudinal Growing Up in Ireland dataset. Particular attention is paid to transitions across the key BMI thresholds of overweight and obesity. Analysis is carried out by...

Much analysis of the socioeconomic gradient of overweight/obesity has involved the calculation of concentration indices for the incidence of these conditions. However this analysis ignores the severity of the conditions, in particular whether there is a gradient to how far are people above the...

This paper examines the change in body mass index for a cohort of Irish children as they aged from 9 to 13 and decomposes the change into parts attributable to changes in observable characteristics and changes in returns to observable characteristics. The decomposition is carried out over the...
