In Touch With Health Matters

There are many different ways to determine body fitness. Often, the level or percentage of fat is a contributor to major diseases. Several ways to test for this include calipers and an immersion method called hydrostatic weighing. Both require consultation with a health care provider. The first includes applications of calipers or clips placed on fat concentrated areas like the upper arm, tummy and the thighs. The latter is the most accurate which require immersion in water. A simpler and less inexpensive way is the BMI or Body Mass Index. This method is not as conclusive as the previous ones, but it is highly suggestive of health problems.

BMI can be calculated by following a simple formula. First, the weight in kilograms is obtained through a standard bathroom scale. Then, the height in meters squared is obtained through a measuring tape. The weight is then divided by the height. The English system also has a BMI formula. The weight in pounds is divided by the height in inches. The result is then multiplied by 703, a standard conversion factor. This is traditionally calculated manually with the use of a calculator.

With the onset of technology and the rise of the internet, modern means are discovered. The BMI weight calculator now exists in the World Wide Web for free. These are now many websites that offer this service which aim to promote health awareness among people. Certain phone applications like the iPhone features a BMI calculator to make every calculator handy, hassle free, effortless and not too costly. The spread of these specialized calculators has allowed everyone to be in touch with reality on their health.

The BMI weight calculator has brought a lot of positive changes in terms of people empowerment. Since the calculator is found everywhere, anyone can be part of the screening and prevention process. This online or phone based application allow lay people to know whether or not their weight per height belongs to the ideal range. By being part of the calculating process, there is more participation and more control. In psychology, people become more interested and thirsty for knowledge if they become a significant member of the process. Moreover, there can be lesser hesitation on the divulging of weight and height part. Some individuals especially women may find it hard or embarrassing to spill out the weight to someone who might ridicule or make fun out of it. Moreover, the cloud of doubt regarding alterations in results is removed because the program is standardized.

This calculator can reawaken consciousness to any person. It is human nature to seek further information or even consultation if anything strange or abnormal is discovered. Whether underweight or overweight, individuals want to look for ways to make them become back in shape once more. As such, the calculator can help anyone realize the importance of being healthy and fit by following a healthy lifestyle. Websites with these calculators usually have side information on proper health habits like eating a balanced diet, regular exercise and sufficient rest or sleep.

How to Calculate LTIFR and Other Health and Safety Indicators

Knowing how to calculate LTIFR and other safety indicators is an important skill to have if you work in the health and safety field. Despite the fact that these indicators don’t reveal a great deal of useful information managers love them and will insist on knowing what they are. They will use them to measure internal health and safety performance and to compare you’re company’s performance with other companies. These are not difficult to calculate and this can be made even easier if you use a spread sheet.

Health and Safety Indicators

Broadly speaking, common health and safety indicators can be divided into two – frequency rates and incidence rates. So what’s the difference?

A frequency rate is an expression of how many events happened over a given period of time by a standardised number of hours worked. An incidence rate is the number of events that happened over a given period time by a standardised number of employees (usually lower than the standardised number of hours). For example, an LTIFR which stands for Lost Time Injury Frequency Rate, is the number of Lost Time Injuries (LTI) that occurred over a period time per 1 000 000 or 100 000 or some other number of hours worked in that period. This could be over a month or a quarter or a year depending on the reporting requirements of your business. To convert this to an incidence rate just substitute the number of employees for the number of hours.

A lot of things are presented in this manner. As well as lost time injuries there are Medical Treatment Injuries (MTI) another is significant injuries which are often categorized as LTIs plus MTIs. A slight variation is the severity rate which is usually a measure of the amount of time lost due to work related injury by some standardised figure that is used to indicate the severity of injuries.

Calculating Frequency Rates

The formula to calculate these indicators is really very simple. Let’s say we want the number of lost time injuries per 1 000 000 hours worked for the last year. You need to get two pieces of information – the number of LTIs that happened in the last year and the number of hours worked in the last year. You could probably get the number of LTIs from your workers compensation claims manager or insurance company and your payroll section should be able to tell you the number of hours worked over the period.

Multiply the number of LTIs by 1 000 000 and divide the result by the number of hours worked and there you have it – the LTIFR. To show it using numbers. Say there were 7 LTIs in the past year and 2 451 679 hours worked. So, 7 X 1 000 000 = 7 000 000. Divide that by 2 451 679 and you get 2.86 – go on, grab your calculator and try for yourself.

What does that mean? It means that this business experienced 2.86 LTIs for every 1 000 000 hours worked over the past year.

Calculating Incidence Rates

Now, to calculate the LTIIR (Lost Time Injury Incidence Rate) which is the number of LTIs per 100 (or whatever figure you want) employees we just substitute the number of employees for the number of hours and multiply the number of LTIs by the standardizing factor which is 100.

So say this mythical business had 791 employees, we get 7 X 100 = 700. Divide this by the number of employees – 791 – and we get 0.88. So for every 100 employees this firm experienced 0.88 LTIs.

Calculating Severity Rates

Finally the severity rate. Depending on how this is expressed you will need at least the information from above and the number of work days lost over the year. Say its 73. Most often the severity rate is expressed as an average by simply dividing the number of days lost by the number of LTIs. So, using the figures we have we get 73 divided by 7 which gives 10.43. That is, on average each LTI will result in 10.5 days off work. It can be converted to a frequency or incidence rate by multiplying the result by a standardizing factor. This, of course will increase the result which is why you don’t see it very often – who wants a severity rate of 104 days off per 100 LTIs?

So there you have it. Not very hard and if you know even a little bit about spreadsheets you can easily insert the formulas into specific cells to calculate these indicators automatically.

What is a BMI Calculator?

There is a good percentage of the population that is very unfamiliar with what a Bass Mass Index (BMI) is. They don’t realize how important this index is to their overall health. The BMI index is what doctors use to determine a persons body fat or health percentile ranking. By using a BMI calculator they can measure a person overall body weight and fat density.

The process doesn’t measure the body fat directly, however the measurement does correlate with a direct measure of body fat. Using a BMI measurement is considered very inexpensive and easy compared to the alternative of paying a company to perform a direct body fat test.

The BMI index uses a person weight and height to determine their overall health percentile ranking. The ranking is age and sex-specific, and not just a genetic reading. After combining a person age and weight, the BMI calculator assigns a number to different categories. The categories are than ranked by levels such as; underweight, healthy weight, overweight and obese. The BMI calculator is not a diagnostic tool, but a gage on a person’s morbidity and/or mortality risk. A doctor will be able to gage if a person weight poses a health risk.

Patients who are classified under the underweight ranking have just as much of a possibility of developing health issues as those who fall under the overweight and obese categories. It just more common to see an overweight patient with health programs than an underweight.

The BMI index was created between 1830 and 1850 by the Belgian polymath Adolphe Quetelet. They were in the process of developing “social physics” when they realized what they had developed was a way to calculate body mass. At the time of development a BMI calculator wasn’t considered to be of much use. During that time your body mass wasn’t link to the number of diseases it is today. Today we understand that obesity can be linked to heart, liver and many bring upon the onset of other diseases such as Diabetes. You BMI can also effect whether or not you qualify for health and/or life insurance. From a health practitioner’s point of view, your BMI is something you want to work with your doctor to keep under control.
