The use of condoms with other contraceptive methods among young men and women.

In a nationally representative sample of sexually experienced youths aged 14-22, 37% of young women and 52% of young men said the condom was the primary method used to prevent pregnancy at last intercourse; an additional 8% and 7%, respectively, said they used a condom at last intercourse; much of this represents dual use [corrected]. Condom use at last intercourse was reported by 25% of young men whose partner was using the pill. Significant independent predictors of condom use with the pill among men included younger age, black race, engaging in fewer nonsexual risk behaviors and having received instruction about HIV in school. Among young women, 21% of those relying on the pill reported also using a condom at last intercourse. For women, independent predictors of dual use included younger age, black race, older age at first sex, fewer nonsexual risk behaviors, having no partners in the previous three months and having talked to parents or other adult relatives about HIV.

Comparison of the metabolic effects of two hormonal contraceptive methods: an oral formulation and a vaginal ring. II. Serum lipoproteins and apolipoproteins.

In a long-term, prospective study the effects on lipoprotein lipids and apolipoproteins (apo) of a combined oral contraceptive (OC) (30 micro gram ethinylestradiol and 150 micro gram levonorgestrel) and a contraceptive vaginal ring (CVR) releasing estradiol (about 180 micro gram per day) and levonorgestrel (about 290 micro gram per day) were compared. The two treatments induced significantly different effects. In the OC group the lipoprotein-lipid concentrations showed only minor changes, but apolipoproteins (apo) B and A-I increased by about 15%. In contrast, during treatment with the CVR there was a 25% decrement of cholesterol in high density lipoprotein (HDL) and at most 10% in low density lipoprotein (LDL) cholesterol, with only minor effects on apo B and A-I. The ratio of LDL and HDL cholesterol increased in the CVR group but not in the OC group. The results also indicate a change in the composition of the LDL and HDL particles, with an altered lipid/protein ratio, during both contraceptive treatments. Despite the impressive relative increase in LDL:HDL ratio in the contraceptive ring group, the average absolute value of this ratio did not reach the mena for healthy men.
