Factors associated with maintenance of regular condom use among single heterosexual adults: a longitudinal study

The aims of this study were to describe behavioural and psychosocial characteristics of single heterosexuals towards regular condom use, and to identify factors associated with the maintenance of this behaviour over time.

A cohort of 179 single heterosexual adults (83 men and 96 women, mean age: 32 years) was followed over a period of 2 years. The data were collected, by phone interviews, at baseline and 1 and 2 years later. The phone numbers were generated using a random digit strategy.

The following changes were observed: over time fewer people were sexually active, but those who were, reported more often having had more than one sexual partner. No significant change was observed regarding condom use. The psychosocial variables remained stable during the study period. To have a favourable intention was the main factor associated with maintenance of condom use. Having had a STD, personal normative beliefs and positive attitude were also associated with regular condom use.

Promotion strategies should highlight the importance of acting as a responsible person, reinforce the advantages of using condoms, and select strategies that favour the implementation of intention of using condoms.
