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.
The authors point to estrogen levels, which rise during puberty and decline later in life, as the likely cause of the widening and subsequent narrowing in the female pelvis, in particular because estrogen is known to impact bone growth and development.
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.
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 an increase in fat distribution in your hips, thighs, and bust region. This is due to metabolic changes, weight gain, and hormonal changes." Aka being in your 20s is a nonstop physical and emotional thrill ride.
Although you can't spot-reduce fat in just one area of your body, you can trim hip fat by losing overall body fat. You can do this through regular fat-burning exercises, cutting back on calories, and toning your lower body.
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.
Diamond. If you have broader hips than shoulders, a narrow bust, and a fuller waistline, you have what's called a diamond body shape.
Usually, we consider hip sizes above 36 or 37 inches curvy and hip sizes below 34 to be a slim silhouette. Also, the waist-to-hip ratios of curvy individuals are often in the range of 0.7 to 0.8.
The idea here is that your waist should be smaller than your hips. If your waist is bigger than your hips, than you may have too much fat concentrated around the middle part of your body - something known as "intra-abdominal obesity".
Based on various studies, the ideal body shape is the hourglass type body shape. The amount of these qualities vary between culture and race, but as long as you hold an hourglass shape, then you have an ideal body shape.

The specific proportions of 36–24–36 inches (90-60-90 centimeters) have frequently been given as the "ideal", or "hourglass" proportions for women since at least the 1960s (these measurements are, for example, the title of a hit instrumental by The Shadows).
Research across a variety of cultures has demonstrated that men typically find the curvaceous female form sexually attractive. Other studies have shown that wide hips in women are associated with health and reproductive potential, so the attraction makes evolutionary sense.
Estrogen helps make women curvier than men by making their pelvis and hips wider, and their breast grow. Estrogen is part of your menstrual cycle, helps you get pregnant, and plays a role in helping you develop bones and grow hair. It also helps regulate your moods and impacts your brain development and structure.
An expanding waistline is sometimes considered the price of getting older. For women, this can be especially true after menopause, when body fat tends to shift to the abdomen. Yet an increase in belly fat does more than make it hard to zip up your jeans. Research shows that belly fat also carries serious health risks.
Weight loss correlated significantly with decreases in the circumference of the waist and hips, and decreases in WHR in men and women. At comparable levels of weight loss, men had greater decreases in the waist, and smaller decreases in the hips than women, resulting in greater decreases in WHR.
Having extra weight on your behind, big hips and solid thighs "is good for you," say British researchers. Carrying fat on the hips, thighs and bottom, rather than around the waist, has a range of health benefits and actively protects against diabetes and heart disease, experts at Oxford University said.
It is normal for changes to start as early as age 8 or as late as 13. Puberty starts when your brain sends signals to certain parts of the body to start growing and changing. These signals are called hormones.
Studies have shown that by the age of 35, the natural aging process causes us to lose about 10% of the fat in our faces, and we lose an additional 5-10% of your facial volume every 5-10 years thereafter.
What should your waist measurement be? For men, a waist circumference below 94cm (37in) is 'low risk', 94–102cm (37-40in) is 'high risk' and more than 102cm (40in) is 'very high'. For women, below 80cm (31.5in) is low risk, 80–88cm (31.5-34.6in) is high risk and more than 88cm (34.6in) is very high.

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.
