OBJECTIVE Our objective was to use longitudinal data from a US birth cohort to test whether the probability of overweight or obesity during the first 6 years of life varied according to socioeconomic status. DESIGN AND METHODS Using six waves of longitudinal data from full-term children in the Early Childhood Longitudinal Study-Birth Cohort (2001-2007; n≈4,950), we examined the prevalence of ...

OBJECTIVE Socioeconomic status (SES) has a known influence on academic achievement. Most studies, however, were conducted in English-speaking countries. Because recent cross-linguistic studies suggest that reading English is much harder to learn than reading other languages, an epidemiological study was conducted in French investigating the impact of socioeconomic background on early reading de...

OBJECTIVES We examined variability in disease rates to gain understanding of the complex interactions between contextual socioeconomic factors and health. METHODS We compared mortality rates between New York and California counties in the lowest and highest quartiles of socioeconomic status (SES), assessed rate variability between counties for various outcomes, and examined correlations betwe...

Bilingual children often outperform monolingual children in tasks of cognitive control. This advantage may be a consequence of the fact that bilinguals have more practice controlling attention due to an ongoing need to manage two languages. However, existing evidence is limited because possible differences in ethnicity and socioeconomic status have not been properly controlled. To address this ...

INTRODUCTION Understanding health inequity is necessary for addressing the disparities in health outcomes in many populations, including the health gap between Indigenous and non-Indigenous Australians. This report investigates the links between Indigenous health outcomes and socioeconomic disadvantage in the Northern Territory of Australia (NT). METHODS Data sources include deaths, public ho...

While a positive relationship between socioeconomic status (SES) and health has been well established, far less clear is how this relationship changes with aging. Using recent data from China’s 2005 Intercensus Survey, we study health differentials by SES and whether they converge, diverge, or remain stable at old ages in China. We found divergence in health differentials with age both by educa...

BACKGROUND Despite the well-established power of frailty to predict mortality, and the known associations of socioeconomic status (SES) with mortality, it is largely unknown whether the linkage between frailty and mortality varies across different SES groups. This study aims to investigate whether SES moderates the association between frailty and mortality. METHODS We relied on the 2008/2009 ...

BACKGROUND Socioeconomic inequalities in longitudinal patterning of childhood overweight could cause marked differentials in total burden by adulthood. This study aims to determine timing and strength of the association between socioeconomic status (SES) and children's body mass index (BMI) in the pre- and primary school years, and to examine socioeconomic differences in overweight trajectories...
