Twenty‐year dynamics in adiposity and blood lipids of Greek children: Regional differences in Crete persist

Abstract

To examine whether secular trends in adiposity and blood lipid profile of Greek children manifested equally among individuals from urban and rural provinces. Cretan boys (aged 12.1+/-2.3 y) from urban and rural areas of Crete were recruited in 1982 (n=277 and 251, respectively) and 2002 (n=440 and 180, respectively). Height, weight, and body mass index (BMI), as well as plasma lipid concentrations were measured and compared across cohorts (1982 vs 2002) and regions (urban vs rural) by two-way analysis of covariance (adjusted for age) with interaction. Temporal changes in height (positive), weight (positive), and BMI (positive) manifested equally in children from urban and rural provinces, as no interaction was detected. Similar results were obtained for triacylglycerol (positive), low-density lipoprotein cholesterol (LDL-C, positive) and high-density lipoprotein cholesterol (negative) concentrations. A significant interaction was observed only for total cholesterol (TC), which increased from 1982 among rural (by 6.2%, p < 0.05) but not among urban boys. In all other instances, regional differences in 1982 persisted in 2002. More specifically, children from urban provinces were taller, heavier, and had higher BMI values than those from rural areas, while they also had higher LDL-C concentrations, whether nowadays or 20 y ago. Regional differences in TC in 1982 were not apparent in 2002. These findings suggest that changes in anthropometric characteristics and plasma lipids during the past 20 y have occurred largely in parallel among urban and rural Cretan children, and they emphasize the importance of developing a common national strategy for the prevention and treatment of childhood obesity in Greece.
