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 |
| Pregnancy and lifestyle study: the long-term use of the contraceptive pill |
| and the risk of age-related miscarriage. |
| HUMAN REPRODUCTION. 1995 Jun;10(6):1397-402. |
| The impact of oral contraceptive use on ovarian follicular dynamics--considered to be a key determinant of trisomic |
| conceptions--was investigated in a prospective study of 585 Australian women who were planning pregnancy. Urine |
| samples were collected on the last day of each menstrual cycle in which conception was attempted; outcomes were |
| classified as live birth of a normal infant, spontaneous abortion, or persisting infertility. Only 39 women had never |
| used oral contraceptives (OCs); the majority had used the pill for at least six months. The age-related miscarriage |
| rate was 13.4% in women aged 25-29 years, 17.3% in those aged 30-34 years, and 28.3% in those aged 35-39 years. |
| The frequency of miscarriage showed a pattern of decline with increasing years of OC use: 0-2, 22.2%; 3-4, 17.3%; |
| 5-6, 19.6%; 7-8, 16.7%; and 9 or more, 11.4%. However, the addition of maternal age to the logistic regression model |
| revealed that the association between OC use duration and miscarriage was significant (p < 0.001) only for women |
| 30 years of age and over. In this latter group. the mean miscarriage rate decreased from 28% with 0-2 years of OC |
| use to 7% with 9 or more years of use. It is hypothesized that the decrease of about 15% in the rate of miscarriage |
| among longterm pill users aged 30 years or over is attributable to OC-related preservation of ovarian follicles and a |
| subsequent reduction in spontaneous abortion due to aneuploidy--a defect related to pre-menopausal declines in |
| follicle numbers. (PubHealth.info Document ID: CONT2T 3012-06) |
