The '''MONICA''' (Multinational MONItoring of trends and determinants in CArdiovascular disease) Project was established in the early 1980s in many Centres around the world to monitor trends in cardiovascular diseases, and to relate these to risk factor changes in the population over a ten year period. It was set up to explain the diverse trends in cardiovascular disease mortality which were observed from the 1970s onwards. There were total of 32 MONICA Collaborating Centres in 21 countries. The total population age 25-64 years monitored was ten million men and women. The ten year data collection was completed in the late 1990s, and the main results were published in the following years. The data are still being used for analysis.

#Summary: This code demonstrates the creation of data replicas with ReplicaX R functions.
#The R functions needed are available as http://www.tilastotiede.fi/ReplicaX/ReplicaX_functions.r
#For information see http://www.tilastotiede.fi/ReplicaX/ReplicaX_esitys.pdf (in Finnish)
#
#The data used is a published sample of WHO MONICA data.
#Before running the code, you should download the data from
#http://www.thl.fi/publications/monica/monograph_cd/data/form04_3.zip
#
#The data documentation can be found at

The MONICA (Multinational MONItoring of trends and determinants in CArdiovascular disease) Project was established in the early 1980s in many Centres around the world to monitor trends in cardiovascular diseases, and to relate these to risk factor changes in the population over a ten year period. It was set up to explain the diverse trends in cardiovascular disease mortality which were observed from the 1970s onwards. There were total of 32 MONICA Collaborating Centres in 21 countries. The total population age 25-64 years monitored was ten million men and women. The ten year data collection was completed in the late 1990s, and the main results were published in the following years. The data are still being used for analysis.

Question

What is the WHO Monica Study?

Answer

Rationale

An rcode for managing the data into a more easily usable format. The produced csv file was then converted to zip and uploaded to File:Monica.zip. The code that produced the data file is documented on File:Monica.zip
