Summary
Hormonal contraceptives like COCs and DMPA may negatively impact adolescent bone health, potentially reducing bone mineral density. More research is needed on long-acting reversible contraceptives (LARCs) and their skeletal effects.
Area of Science:
- Endocrinology
- Adolescent Medicine
- Bone Biology
Background:
- Hormonal contraceptives are widely used by adolescents for various health reasons.
- Adolescence is a critical period for achieving peak bone mass and skeletal strength.
- The effects of hormonal contraceptives on adolescent bone health are not fully understood and may differ from those in mature women.
Purpose of the Study:
- To critically review the current knowledge regarding the skeletal effects of hormonal contraceptives in adolescents.
- To identify gaps in research concerning combined oral contraceptives (COCs), depo medroxyprogesterone (DMPA), and long-acting reversible contraceptives (LARCs).
Main Methods:
- Review of existing literature on hormonal contraception and adolescent bone health.
- Analysis of studies investigating the impact of COCs, DMPA, and LARCs on bone mineral density (BMD) and fracture risk.
- Examination of hormonal and growth factor pathways (estrogen, IGFs) influencing bone development.
Main Results:
- Combined oral contraceptives (COCs) and depo medroxyprogesterone (DMPA) may compromise bone mineral density accrual during adolescence.
- Some studies link contraceptive use to slower BMD gains and increased fracture risk in teens.
- Limited data exists on the skeletal effects of newer long-acting reversible contraceptives (LARCs) in adolescents.
Conclusions:
- Hormonal contraceptives, particularly COCs and DMPA, may have detrimental effects on adolescent bone acquisition.
- Further research is essential to elucidate the long-term skeletal consequences of various contraceptive methods in adolescents.
- Understanding these effects is crucial for optimizing adolescent health and preventing future bone-related issues.

01:17Hormones and Bone Tissue
3.5K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:29Bone Disorders
5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:40Bone Remodeling
39.8K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:30Hormonal Control of the Ovarian Cycle
6.1K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

01:27Signs of Puberty
1.1K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

01:25Role of Vitamins in Maintaining Bone Health
4.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
