BACKGROUND:

The choice of a birth control method is influenced by sociocultural and personal factors. We explored the perceived influences in women’s choice of a birth control method in five European countries (Germany, France, the UK, Romania and Sweden), where contraception is widely used.

STUDY DESIGN:

This is a cross-sectional study of 1137 randomly selected women aged 18-49 years. An anonymous, 31-item questionnaire related to birth control methods was used. Logistic regression was used to identify variables associated with partner participation in choice of a contraceptive.

RESULTS:

Oral contraceptives were mainly used in Germany (54.3%), France (50.5%) and Sweden (34.6%) and condoms in the UK (29.6%) and Romania (22.9%). Sweden showed the highest use of intrauterine devices (IUD, 19%). Romania had the lowest use of contraception. Oral contraceptives and IUDs use were frequently suggested by providers instead of by women. Choosing the method with the partner was associated with age [odds ratio (OR)=0.97, 95% confidence interval (CI) 0.94-0.99], being a university graduate (OR=1.59, 95% CI 1.01-2.29), married (OR=1.52, 95% CI 1.01-2.29) and with using a method that requires partner’s cooperation (OR=8.18, 95% CI 5.46-12.27).

CONCLUSIONS:

Hormonal contraceptives and IUDs are commonly recommended by providers rather than requested by women. Partner preferences are taken into account when his cooperation in the use of the method is needed. As fertility care is a male and female issue, there is still more room for actively involving both women and men in their choice of a birth control method.

Abstract

In the Democratic Republic of Congo no previous studies have assessed the factors associated with different patterns of condom use and with multiple sexual partners, and the association between condom use simultaneously taking into account multiple sexual partnerships, and HIV infection. We carried out a prospective case-control study. From December 2010 until June 2012, 1630 participants aged 15-49 getting HIV Voluntary Counseling and Testing in a hospital in Kinshasa were selected. Cases were new HIV diagnosis and controls were HIV-negative participants detected along the study period. We recruited 274 cases and 1340 controls that were interviewed about HIV-related knowledge, attitudes and behaviours. Among cases there was a high prevalence of multiple lifetime and concurrent sexual partnerships (89.8% and 20.4%, respectively) and most cases never used condoms with only 1.5% using them consistently. Condom use and multiple partnerships were associated with male, single and high-educated participants. An association was found between multiple lifetime partners and ‘any condom use’ (OR = 2.99; 95%CI: 2.14-4.19) but not with consistent use. Both having two or more multiple concurrent sexual partners or not using condoms were variables similarly and highly associated to HIV risk. The association found between having two or more concurrent sexual partners and HIV was slightly higher (OR = 3.58, 95%CI:2.31-5.56) than the association found between never condom use and HIV (OR = 3.38, 95%CI:1.15-9.93). We found a high prevalence of multiple lifetime sexual partners and an extremely high prevalence of inconsistent condom use, both strongly associated with HIV seropositivity. Local programmes would benefit from comprehensive interventions targeting all behavioural and sociocultural determinants.
