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. |

| Purpose: To conduct a longitudinal comparison of bone mineral density (BMD) in 370 adolescent girls, aged 12-18, |
| who self-selected depot medroxyprogesterone acetate (DMPA) or an oral contraceptive (OC) containing 20µg ethinyl |
| estradiol/100µg levonorgestrel with that in girls who received no hormonal treatment (control group). Methods: Lumbar |
| spine and femoral neck BMD measurements were obtained by dual energy x-ray absorptiometry at baseline and 12 |
| months. Data were analyzed with repeated measures analysis of covariance methods. Results: Over 12 months, |
| lumbar spine BMD decreased in the DMPA group (n = 29), with a mean percent change of -1.4% (95% confidence |
| interval [CI] - 2.73, -0.10), and increased by a mean of 3.8% (95% CI 3.11, 4.57) in the control group [n = 107 (p < |
| .001)]. The increase in mean percent change in lumbar spine BMD in the OC group (n = 79), 2.3% (95% CI 1.49, |
| 3.18), was significantly smaller than in the control group (p = .03). Over 12 months, the mean percent change in |
| femoral neck BMD was -2.2% (95% CI -3.95, -0.39) in the DMPA group, but increased 2.3% (95% CI 1.29, 3.27) in the |
| control group (p < .001). The increase in mean percent change at the femoral neck in the OC group, 0.3% (95% CI - |
| 0.87, 1.41), was significantly lower than in the control group (p = .03). Conclusions: Our study contributes to an |
| increasing body of knowledge indicating a negative impact of DMPA on bone health in young women. Additional |
| findings suggest a potential adverse effect of an OC containing 20 µg ethinyl estradiol/100 µg levonorgestrel on bone |
| health in adolescents. (PubHealth.info Document ID: CONT1T 522-06) |
