Detailed Description
-----------------
Hypertension incidence and overweight or obesity related, constitute a worrying public health problem nowadays. In this sense, healthy eating and regular physical activity have demonstrated a relevant role maintaining health while ageing. Information and Communication Technologies (ICTs) have been shown as a useful way to promote health, improving motivation and overcoming difficulties to maintain a healthy lifestyle. ICTs also reach a wider audience at a lower cost, due to their good cost-benefit relationship and the possibility of increasing the efficiency of interventions. This research will constitute a 3 years follow-up which includes a re-assessment and re-intervention of obese or overweight adults with hypertension, recruited from a hypertension unit of a public hospital, that already participated in a similar program 3 years ago. At the same time, the aim of the study is to analyze the effects of the current program, which will take 3 months and promotes lifestyle changes focusing on healthy eating and increased physical activity in their 9 modules, comparing the results obtained in 2018. These patients will be allocated into one experimental group. Assessment will include: Blood Pressure, Body Mass Index, Physical Activity levels, and adherence to the Mediterranean diet.
