Study objective: To study the socio-demographic determinants of body-height and the bearing of these determinants on the association between body-height and health among Finnish adults.
Data and method: Cross-sectional population survey including questions on social background, body-height and health, and retrospective questions on childhood living conditions. The data derive from a representative Survey on Living Conditions collected by Statistics Finland in 1994. The response rate was 73%. Male and female respondents > or =20 years were included in the analysis (N = 8212). Statistical methods include regression analysis and logistic regression analysis.
Results: Body-height was strongly associated with year of birth, region, childhood living conditions and education among adult men and women. Body-height was also associated with limiting long-standing illness and perceived health as below good. Tall men had the best health and short men the poorest health. Among women the association of body-height with health differed from men, as tall women showed high levels of limiting long-standing illness, notably musculo-skeletal diseases. Adjusting for the background variables weakened but did not abolish the association between poor health and short stature among men and women.
Conclusions: Short stature is associated with poor health among Finnish men and women. A non-linear association among women was found for musculo-skeletal diseases. The studied social background factors explained only little of the association between body-height and health.
