This study aimed to investigate contraceptive use and its determinants in K
ocaeli, Turkey. A questionnaire was applied to 922 randomly selected sexual
ly active women of reproductive age, in order to extract information concer
ning contraceptive use and sociodemographic factors affecting behavior and
contraceptive use. Knowledge of at least one method was nearly universal. I
ntrauterine devices and withdrawal were the most commonly used methods. Ill
iterate women and housewives had less knowledge about some modern methods.
The number of children (p <0.001), nuclear type family (p <0.05), and appro
val of family planning (p <0.001) were the factors most predictive of contr
aceptive use. Husbands were involved in family planning via discussing fami
ly size (79.4%) and method (85.5%); 38.2% of males participated actively by
using withdrawal or condom. Increasing the literacy of both male and femal
e partners significantly increased both contraceptive use and the participa
tion of husbands in family planning descision making. In conclusion, increa
sing the education level of couples and the status of women would result in
increased contraceptive use in the future. Since the contraceptive behavio
r of women is influenced by their husbands' attitudes, family planning prog
rams should be focused on the needs of both partners.
