In a cross-sectional study of a total population aged 70 years and ove
r in a rural New Zealand township (sample size 682) we investigated fa
ctors which characterize those who felt they had a great deal of contr
ol and those who felt they had little or no control over future health
. In a significant logistic regression model those with a feeling of a
great deal of control over future health had a lower prevalence of ch
ronic obstructive lung disease, higher prevalence of diabetes, took le
ss alcohol, were more likely to be satisfied with bowel function, had
a lower protein intake, were more likely to participate in strenuous t
o moderate activity and were less likely to have features of depressio
n. Different perceptions of control were associated with significant d
ifferences in health practices and health status.
