BMI Chart For Females- know its benefits and how to use it

A person’s BMI value measures how much body fat they have based on their height and weight. Children and adolescents have a greater range of healthy BMI readings than adults due to their different rates of growth, although the range stays constant for adults. Mathematician and sociologist Lambert Adolphe Jacques Quetelet first created the BMI formula in the 19th century. It was initially intended to be used in broader population studies and to estimate the prevalence of obesity in industrialized western nations. Since the 1980s, worldwide organizations like the WHO have used it as a benchmark to assess the prevalence of obesity.

Body Mass Index, or BMI, measures the correlation between your height and weight, two important body parameters. The following BMI calculation formula specifically uses these two factors to determine BMI:

                                        BMI :  Weight/ height²

This formula’s key observation is that the units you choose DO matter. Use the metric system, which converts your weight and height into kilograms and meters, to determine what a normal BMI is and where you fall between the BMI ranges.

Although BMI is not a precise indicator of any health-related factors, it is a useful statistical tool. It helps to determine whether there is something seriously wrong with our bodies and whether we should be concerned about health issues. BMI has numerous shortcomings that we will discuss later and was never intended to be a diagnostic tool. However, due to its ease of use, it is particularly useful as a first-approach tool to statistically identify if someone is overweight or underweight so that you may begin examining the causes and potential health hazards.

Benefits of BMI

To follow obesity at the population level, which is crucial for medical research, BMI is one of the best, simplest, and least expensive choices available to researchers.

Additionally, research has shown that a person’s body mass index (BMI) can accurately predict their risk of contracting diseases and dying from them. A high BMI is associated with increased body fat levels.

Obese people have been demonstrated to have a much higher risk of premature death. Chronic diseases and renal disease are seen more than people with BMIs that fall within the “normal” range.

People with a BMI that places them in the underweight category are also more likely to die young and get sick.

A person’s BMI should not be considered a reliable indicator of their health on its own. But healthcare practitioners can use BMI in conjunction with other diagnostic techniques to evaluate a person’s health.

Other measurements include the waist circumference and lab results like cholesterol levels.

Issues Faced While Using BMI

For a variety of reasons, using BMI as a health indicator is hazardous.

Even though some medical practitioners use BMI to classify people according to their body fat, this metric doesn’t genuinely consider lean body mass or body fat. This implies that BMI doesn’t distinguish between fat and muscle.

Because of this, even if a person has low levels of body fat, their BMI may classify them as overweight or obese if they have a relatively high percentage of muscle mass.

The fact that BMI is unable to pinpoint the location of body fat storage is another flaw in the calculation. As a result, it doesn’t take into consideration differences in the distribution of fat across sexes or between body types. Additionally, the loss of muscular mass with age is not taken into account.

Even if a small-framed person has a lot of belly fat, the system can still designate them as having a healthy BMI range.

However, given that belly fat is strongly associated with numerous chronic conditions and early mortality, this person may be at risk.

In other words, even if a person has a “healthy” BMI, they could nevertheless be significantly more likely to develop an illness, experience surgical complications, or experience an elevated death rate.

The concept of health has many different aspects. When determining their general health and disease risk, a person should take a variety of things into account.

BMI is too rudimentary of a measure, according to experts, to be used as a health predictor.

What Is The Difference Between Female And Male BMI

Even among individuals with the same ratios of body fat and muscle, the body forms of women vary significantly. For instance, the size, shape, and hip-to-waist ratio of the bust. Even among women, there are often more differences between the legs than there are between men.

Because they were created entirely theoretically, the BMI ranges for women are the same as those for men. The narrative drastically alters if you look at the percentile BMI ranges, though. Compared to men, women have a substantially wider range of BMI levels. To further grasp this, let’s look at an illustration.

If we contrast the percentages for women’s BMIs at the 95th and 5th percentiles with those for males. There is an unexpected element. In all age categories, women have lower 5th percentile limits than males, but at the same time, they also have larger 95th percentile limits. So, unlike for males, women’s BMI distribution is more uniformly distributed and not skewed toward higher or lower BMI.

This indicates that there are proportionately more women than males at the extremities of the BMI ranges. There are two potential causes for this, and both of them are likely active. First, it can result from the previously noted variety in body types. Women can have BMIs that are nevertheless deemed healthy due to the wide variety of female body shapes.

How BMI Is Different For Different Women

Even though a chart may be useful, BMI is not a universal idea. Depending on a person’s ethnicity, level of muscle, and other characteristics, doctors may advise various cutoff criteria.

1. Athletes and Bodybuilders

Despite having low levels of body fat, the BMI system frequently misclassifies women with substantial quantities of muscle mass as overweight or obese. Bodybuilders and professional athletes are among those that fall within this category.

This is the reason why individuals shouldn’t use BMI as a gauge of body composition as it doesn’t distinguish between muscle mass and fat mass.

2. South Asian and Asian women

The body fat percentage of Asian and South Asian communities is higher about their body weight than that of white populations.

According to research, type 2 diabetes occurs in Asian populations at lower BMI levels than in white ones.

As a result, BMI cutoffs for Asian people have changed.

Asian and South Asian women are considered to be obese if their BMI is greater than 27.5 and overweight if it is between 22.5 and 27.5.

3. White, Black, Hispanic Women

Women of all races who have a BMI between 18.5 and 24.9 are regarded as being at a “healthy weight.”

The Centers for Disease Control and Prevention (CDC) states that a woman who is 65 inches (1.65 meters) tall and weighs between 111 and 150 pounds would have a normal BMI (50–68 kg)

Women, however, have various physical types and compositions.

Research has shown, that Mexican American women often have a distinct distribution of body fat than white or Black women. Additionally, compared to white or Mexican American women, Black women often have more muscular mass.

Mexican American women typically have greater abdominal fat than other women. According to one study, Mexican American women with identical BMIs may have 3-5% higher body fat and a bigger waist circumference.

However, a person’s weight, body fat percentage, percentage of muscle mass, waist size, or other physical characteristics are not influenced by their ethnicity. Every individual is unique.

Even if two women have the same BMI, their regional body fat distribution and muscle mass may differ significantly. Researchers also admit that there is a considerably smaller correlation between BMI and mortality risk for Black women than for White women.

This is because BMI is a less reliable predictor of body fat levels in Black women and, generally, their fat distribution differs from that of White women. Additionally, unlike in the case of white women, Black women’s blood fat levels are not related to BMI.

4. Postmenopausal Women

Compared to younger women, older women often have less muscle mass and greater belly fat.

Age-related changes in hormone levels, a decline in physical activity, and changes in torso length brought on by osteoporosis are the causes of these alterations.

While an older woman and a younger woman may have the same BMI, the older woman is more likely to have more body fat and less muscle mass, which raises her risk of illness.

Postmenopausal women showed that the BMI criterion of 30 was not a reliable indicator of obesity in this population. The researchers emphasized that even in many obese postmenopausal women, BMI may not be an accurate indicator of obesity.
