BACKGROUND Education and wealth may have different associations with female obesity but this has not been investigated in detail outside high-income countries. This study examines the separate and inter-related associations of education and household wealth in relation to obesity in women in a representative sample of low- and middle-income countries (LMICs). METHODS The seven largest nationa...

Cognitive abilities rise steeply from infancy to young adulthood and then are either maintained or decline to old age, depending on the specific ability. This pattern suggests corresponding continuities of mechanism and process, but it is striking that the fields of cognitive development and cognitive aging make little contact with each other's methods and theories. In this review we examine re...

We studied the developmental trends of temperament and character in a longitudinal population-based sample of Finnish men and women aged 20-45 years using the Temperament and Character Inventory model of personality. Personality was assessed in 1997, 2001, and 2007 (n = 2,104, 2,095, and 2,056, respectively). Mean-level changes demonstrated qualitatively distinct developmental patterns for char...

We describe gene-environment processes that may help account for individual differences in successful aging. Our emphasis is on successful aging in the cognitive domain, wherein individuals come to use a variety of strategies to cope with changes in cognitive capacities. We focus on the role of executive control in particular and define gene-environment correlation and nonshared environmental m...

Large Demographic Shocks and Small Changes in the Marriage Market This paper provides non-parametric estimates of the total effects of famine in China on marital behavior of famine affected cohorts in rural areas of Sichuan and Anhui.

Internal migration has an important role in population redistribution and development. It is instrumental in the redistribution of human resources and productivity improvements. Migration is multi-dimensional in nature, involving temporal and spatial dimensions. This paper uses the 2 per cent sample data from the 1991 and 2000 population censuses to examine the levels and patterns of inter-stat...
