The present study examines patterns and socioeconomic and demographic correlates of adult height among Sri Lankan adults. Data were available for height and socio-demographic factors from a nationally representative cross-sectional sample of 4477 subjects above 18 years. Recruitment was between 2005 and 2006. Mean age of all subjects was 46.1 ± 15.1 years. Mean height of males and females were 163.6 ± 6.9 cm and 151.4 ± 6.4 cm respectively. Mean height showed a significant negative correlation with age (p < 0.001, r = -0.207). Highest mean height in females 154.0 ± 5.9 cm and males 165.6 ± 6.9 cm were observed in those born after 1977. Rural females (151.4 ± 6.2 cm) were significantly taller than the urban (151.3 ± 7.2 cm). However, this was not observed in males. In multivariate analysis, year of birth, level of education and household income were significantly associated with height. Height demonstrated a significant negative correlation with systolic blood pressure (r = -0.032), presence of diabetes (r = -0.069), total cholesterol (r = -0.106), HDL cholesterol (r = -0.142) and LDL cholesterol (r = -0.104). Height was associated with household income and level of education in Sri Lanka and demonstrated a distinct increasing trend over successive generations. © 2010 Elsevier B.V. All rights reserved.
