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. |

Contraception (Birth Control) and Family Planning |
| Natural family planning. Effective only if used perfectly [letter] |
| BMJ. British Medical Journal. 1993 Oct 16;307(6910):1003. |
| An article in an earlier issue of the journal is misleading and an uncritical assessment of the efficacy of periodic |
| abstinence as a family planning method. The author overlooks the methodological and design weaknesses of many |
| studies of periodic abstinence. A reanalysis of the data from the WHO multicountry clinical trial of the ovulation |
| method, to which the author refers, reveals the probability of method failure during the first year of perfect use which |
| is 3.1%, while that of imperfect use is 86.4%. The ovulation method allows little to no leeway for imperfect use. In the |
| WHO trial, imperfect use occurred in 10.7% of cycles, and 54.1% of women always used the ovulation method |
| perfectly. Thus, the relatively small proportion of cycles of imperfect use does not denote overall efficacy of periodic |
| abstinence. The limited imperfect use resulted in 20.4% of all women conceiving within 1 year of using the ovulation |
| method. Despite what the author claims, people do not use natural family planning due to the high failure rate among |
| typical users. A lengthy sexual abstinence (50% of the menstrual cycle) and continual monitoring of physiological |
| symptoms also contribute to the low acceptance rate. For real freedom to choose a family planning method, potential |
| users must be well informed. This requires accurate information on safety and efficacy about all methods. This |
| includes informing them that periodic abstinence, when used perfectly, is efficacious; when used imperfectly, has a |
| high risk of pregnancy; and requires lengthy abstinence. These facts disprove the author's claim that periodic |
| abstinence may be the family planning method of choice for developing countries. (PubHealth.info Document ID: |
