Abstract:
Abstract : Background: Adult height is affected by genetic factors, nutritional
status and the secular trend observed in many populations. There are no studies
examining adult height among Sri Lankans. We aimed to determine patterns and
correlates of height among adults in Sri Lanka. Methods: Data were available for
height and socio- demographic factors from a nationally representative sample of
4477 Sri Lankans above 18 years from the Sri Lanka Diabetes and Cardiovascular
Study. Data were analysed using SPSS. Mean height between groups were
compared by students t-test. Results: Males were 39.5% and the mean age was
46.1 (SD 15.1) years. The mean height of all adults, males and females were
156.2cm (SD 8.9), 163.6cm (SD 6.9) and 151.4cm (SD 6.4) respectively
(p<0.001males vs. females). The mean height showed a significant negative
correlation with age (p<0.001). The highest mean height in females 155.4 cm (SD
5.4) and males 163.4 cm (SD 8.7) were observed in the 18-19 year and 20-29 year
age-groups respectively. Urban males were significantly taller than the rural
(urban 164.6cm ± 7.2), rural 163.4cm ± 6.8, p<0.001). This was not observed in
females. Mean height correlated with the level of income (p<0.001). Height
showed a significant negative correlation with diabetes (r= - 0.069) Conclusions:
There was a secular trend in adult height in Sri Lanka. Adult height is also
associated with gender, family income and area of residence. The negative
correlation of height with diabetes needs to be further studied
