The objective of the study was to determine trends in age-specific blood pressure (BP) distribution and @entity101 prevalence in an urban Indian population. In successive @entity101 epidemiological studies (1995 and 2002), randomly selected 2212 subjects (1412 @entity1 , 797 @entity1 ) in the first and 1123 subjects (550 @entity1 , 573 @entity1 ) in the second study were evaluated. BP was measured using World Health Organization guidelines and @entity101 diagnosed using the American Joint National Committee-VI report. Age-specific BP levels in the first and the second study were determined and compared. The mean values of systolic and diastolic BP were not significantly different in various age groups in the first and the second studies. There was an increased variance in the second study as denoted by the significant increase in standard deviations and coefficients of variation in systolic as well as diastolic BP levels at age groups > or =50 years in @entity1 and > or =40 years in @entity1 (P<0.05). The age-adjusted prevalence of @entity101 (known or BP > or =140/> or =90 mmHg) in the first study was 29.5% ( @entity1 ) and 33.5% ( @entity1 ), and in the second study was 30.0% ( @entity1 ) and 30.3% ( @entity1 ) (P=NS). In the second as compared to the first study, there was decrease in age-adjusted prevalence of stage I @entity101 ( @entity1 16.8 vs 24.9%, @entity1 15.4 vs 27.5%), and increase in stage II @entity101 ( @entity1 11.7 vs 2.8%, @entity1 18.8 vs 3.1%), and combined stage II and III @entity101 ( @entity1 13.5 vs 4.7%, @entity1 16.7 vs 6.0%) (P<0.01). This change was associated with greater prevalence of @entity28 in the second study. In conclusion, increased systolic and diastolic BP dispersion over a 7-year period in this urban population is associated with unchanged @entity101 prevalence, decline in stage I @entity101 and upsurge in more severe grades. Increasing environmental factors, particularly @entity28 , appear important.

Increased variance in blood pressure distribution and changing XXXX prevalence in an urban Indian population.
