A new study has found evidence that, even though you're not getting taller anymore, the pelvis ("hipbones") does continue to widen as people advance in age from 20 years to 79 years. By the age of 20, most people have reached skeletal maturity and do not grow any taller.
You can now blame your bones. Most people don't grow any taller after the age of 20, but a recent study published in the Journal of Orthopaedic Research found evidence that the pelvis -- the hip bones -- continues to widen in both men and women up to about age 80, long after skeletal growth is supposed to have stopped.
Using CT scans, they determined that the width of people's pelvises continued to grow after skeletal maturity was reached at age 20. Specifically, the pelvic inlet widened–evidence of actual pelvic growth.
No, you're not just imagining it: Your hips really do get wider as you get older, according to a new study. Even though most people stop growing in height by the time they hit age 20, researchers have found evidence that the hip bones can keep growing even as people enter their 70s.
For example, as estrogen levels rise after puberty, it prompts the pelvis to widen so that it's at its widest from the ages of 25 to 30–peak fertility years–to make it easier to give birth to human babies, whose large heads need the extra room when getting pushed through the birth canal.
With the onset of puberty, the male pelvis remains on the same developmental trajectory, while the female pelvis develops in an entirely new direction, becoming wider and reaching its full width around the age of 25-30 years. From the age of 40 onward, the female pelvis then begins to narrow again.
In your late 20's you may also notice your body becoming curvier than it was in your early to mid 20's. Due to metabolic and hormonal changes, some women experience increased body fat, making them naturally curvier.
But researchers at the University of North Carolina at Chapel Hill School of Medicine found that while people don't grow taller after age 20, they do grow wider—well into their 70s. On average, the pelvic width of the oldest people in the study was nearly 2.5 cm larger than the youngest patients.
As we get older, our hips slightly widen naturally. One study found that between participants age 20-79, the oldest participants had wider hips than the youngest participants by an inch on average.
So, as you grow taller, your body starts producing all kinds of hormones, which are chemicals that tell parts of your body what to do. During that time of growth, your hips widen (depending partly on what your genes, aka heredity, told them to do!)
Similarly, the waist measurement of women 18-29 years old is about 71.4 cm, the hip circumference is 88.5 cm. Women aged 30 to 49 years, waist measurement is 76.1cm, hip measurement is 90.7cm and in the final age range, waist-hip measurement is 79.2cm - 90.7cm.
Puberty usually starts when you're between 9 and 13 years old. But it can start earlier or later. Thanks to hormones like estrogen, you'll notice changes like your breasts starting to grow and new curves forming on your body. You might notice that you start to get taller, and eventually you'll get your period.
Common causes of hip pain in young adults are labral tear, femoroacetabular impingement (FAI hip impingement), developmental dysplasia, AVN (avascular necrosis), early arthritis, muscle or tendon injuries, or trochanteric bursitis.
Complete lots of lower body workouts such as squats, lunges, curtsy lunges, deadlifts, and glute bridges. Train your lower body 2-3 times a week, doing 3-4 sets of 12-15 reps each. Side leg raises, hip raises, and squat kicks are also good options.
Widening of the hip bones occurs as part of the female pubertal process, and sex hormones in females (estrogens) cause a widening of the pelvis as a part of sexual differentiation. Hence females generally have wider hips, permitting childbirth.
Pear Shape. The main characteristic of Pear shape are: A defined waist. Larger hips and thighs.
Other studies have shown that wide hips in women are associated with health and reproductive potential, so the attraction makes evolutionary sense.
The waist to hip ratio compares the size of your waist, to your hip measurement. If your hips are bigger than your waist you are a pear shape. If your waist is bigger than your hips, you are an apple shape.
No. Seeing at least the outline or hint of your hip bones is natural, normal and healthy. If you look like this and someone (generally another woman, men would be too busy checking you out) says that you are too skinny, that's likely jealously talking.
Estrogen is actually a group of sex hormones, each of them performing different roles in women's health and development. Estrogen helps make women curvier than men by making their pelvis and hips wider, and their breast grow.
Your Hips Get Wider
For most women, these enlarged bones go back to their original place by about 18 weeks postpartum, but some women keep the extra girth permanently.
While there are positive changes, such as reaching maximum bone mass and muscle strength, many women also gain weight during their 20s. Weight gain can happen due to a number of reasons. Hormonal changes can lead to fat being stored in different areas of your body, and you might notice this in your hips or other areas.
"Many people in their 20s might thus notice subtle changes to how their body is shaped or rests compared to when they were in their teens," adds Dr Kennedy. "It's natural and normal to notice slight incremental weight gain as we move through the mid to late 20s."
