title: Factors associated with hypertension prevalence, awareness, treatment and control among participants in the International Mobility in Aging Study (IMIAS).
abstract: The aim of this study is to assess the factors associated with hypertension prevalence, awareness, treatment, and control, in the elderly populations of the International Mobility in Aging Study (IMIAS). Approximately 200 men and 200 women aged 65-74 years were recruited at each site (n=1995) during IMIAS' 2012 baseline survey at five cities: Kingston (Canada), Saint-Hyacinthe (Canada), Tirana (Albania), Manizales (Colombia) and Natal (Brazil). Blood pressure and anthropometric measurements were taken at participants' homes. Hypertension prevalence ranged from 53.4% in Saint-Hyacinthe to 83.5% in Tirana. Diabetes and obesity were identified as risk factors in all cities. More than two-thirds of hypertensive participants were aware of their condition (from 67.3% in Saint-Hyacinthe to 85.4% in Tirana); women were more aware than men. Awareness was positively associated with diabetes in Kingston, Manizales and Natal. Though most of those aware of their hypertensive condition were being treated pharmacologically, associations between awareness and physical activity and refraining from smoking were weak. Control among treated hypertensive participants was low, especially in Tirana and Natal. Diabetes and physical inactivity were associated with poor hypertension control. Hypertension is common in the older populations of IMIAS. Diabetes is strongly associated with hypertension prevalence, awareness and lack of control of hypertension. The fact that awareness is not strongly associated with healthy behaviours suggests that antihypertensive medication is not accompanied by non-pharmacological therapies. Improved health behaviours could strengthen hypertension control. Efforts should be made to increase men's awareness of hypertension. Hypertension control in diabetic patients is a challenge.
