PubHealth.info® (a subsidiary of PakMed) presents scientific information mainly based on abstracts of articles published on a variety of public health issues/topics, particularly encompassing population planning, disease prevention, maternal and child health, and communicable and non-communicable diseases (like HIV AIDS, malaria, etc) that are affecting a significant portion of population in developing and developed countries. Here you can find abstracts of articles published on a variety of public health topics under category "Contraception (Birth Control) and Family Planning". Contraception (birth control) is a regimen of one or more actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant or giving birth. Therefore contraception is the utilization of various and sundry surgical procedures, devices, practices, agents, or drugs with the intention of preventing conception or impregnation (pregnancy). Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically.

ABSTRACT

This study compared 84-day bleeding patterns after immediate initiation of a triphasic oral contraceptive with a 25-µg

daily dose of ethinyl estradiol (E2) compared with the contraceptive vaginal ring, which has a 15-µg daily dose of

ethinyl E2. This was an open-label controlled trial. We randomly assigned 201 women to immediate start of a

contraceptive pill or immediate start of the ring in a 1:1 allocation ratio. Our primary outcome was difference in mean

bleeding - spotting days per woman according to treatment assignment. Secondary outcomes were differences in

World Health Organization- defined menstrual indices, differences in perceived bleeding changes, and differences in

bleeding according to cycle day at the start of method. The mean bleeding-spotting days in the 84-day reference

period for all subjects was 19.2 days (17.0 days for ring users and 21.4 days for pill users, mean difference 4.4 days).

Using the World Health Organization menstrual indices, the ring users experienced fewer days or episodes of

bleeding-spotting and shorter intervals. Among ring users, no baseline characteristics were associated with bleeding

outcomes. Older nulliparous pill users, however, reported more bleeding-spotting days. Significantly more ring users

reported a decrease in duration of bleeding compared with pill users (P < .01). We found no significant differences in

bleeding patterns based on analysis of cycle day at study enrollment. Our study shows advantageous bleeding

patterns for subjects using the contraceptive vaginal ring. It also confirms our previous findings that immediate start

of hormonal contraception is an acceptable alternative to waiting for menses. (PubHealth.info Document ID:
