Background
Medicines are often prescribed to older individuals. Of the individuals of 55 years and older, over 50% are taking any prescribed medication (1). The proportion of individuals taking any medication is even up to 80% in individuals of 75 years and older (1).

Polypharmacy is often defined as the use of five of more medicines (2) and this is also prevalent in the older population. Polypharmacy is related to adverse outcomes such as nursing home admission adverse drug reaction, falls and fractures (2,3,4).

Measurement instruments in LASA
Medication use was assessed during the medical interviews of each wave. Respondents were asked to show their medication containers to the interviewers. Participants were asked to show only the medicines that were prescribed by a physician and that were used currently. The name, dose, frequency of intake, and duration of use of every medicine was recorded. In some waves, information on corticosteroid use in the last three years and on over-the-counter multivitamin use was asked.

All medications were recoded into ATC-codes, which are official international codes, based on indication and substances. In addition, new variables were created containing the user status of several medication groups (user versus non-user). So far, variables were created for anti-depressants, benzodiazepines, oral antidiabetics, insulin, inotropics, antiarrhytmics, nitrogens, anti-hypertensive drugs, diuretics, peripheral vasodilators, anti-lipaemics (for the medicines included in the different groups, syntax is available at LASA.

More information on the ATC codes can be found on the website of the World Health Organisation. This website can be used to create additional groups of medicines.
