One-year XXXX incidence and its predictors in a working population: the IHPAF study.

@entity1 @entity167 @entity101
THE AIMS OF OUR STUDY WERE: (i). to estimate the yearly incidence rates based on one vs two visits in a working population and (ii). to identify incident @entity101 modifiable risk factors. A total of 21566 normotensive subjects were included in a 1-year cohort study. Blood pressure (BP) levels at inclusion and at the second year screening were measured on the basis of two visits, that is, if BP was over 140/90 mmHg in untreated subjects, they were invited to a control visit 1 month later. Height and weight were measured and behavioural risk factors were collected. Among the 17465 subjects who completed the entire protocol (9691 @entity1 and 7774 @entity1 ), 17026 remained normotensive at a 1-year interval and 439 (325 @entity1 and 114 @entity1 ) became @entity101 . Crude yearly incidence rates based on one visit were 6.21% in @entity1 and 3.06% in @entity1 , compared with 3.04% in @entity1 and 1.34% in @entity1 when incidence rates were based on two visits, a more than twofold difference. Age and body mass index at baseline were the two major independent determinants of incident @entity101 in both genders. Smoking and @entity167 consumption were significant risk factors in @entity1 but not in @entity1 , and a low educational level only in @entity1 . BP measurement on separate occasions is necessary to avoid overestimation of incidence. Weight in both genders and @entity167 consumption in @entity1 were the main modifiable predictors of @entity101 .
