Childhood Obesity Screening

By George Fernandez

·         The simple color coded charts (in English units: lbs, Inches) included in these books will provide the necessary tools for parents to monitor the growth patterns of their children and detect the early signs of obesity. 

·         The childhood BMI charts used by pediatricians are not user-friendly and not easily understandable by everyone. 

·         Thus, parents can prevent their child from becoming overweight by tracking their child’s growth (using the methods recommended in this book) and by seeking professional advice and appropriate intervention if necessary. 

·         In addition, parents can record their child’s health (0 to 20 years), medical records, and family health history directly in the book and teach their children to monitor their own growth. 

·         I strongly believe that parents can influence the outcome of the childhood obesity epidemic, but they often miss the early signs of their children becoming overweight.  I hope to address this problem with my book.

BMI Made Simple: What Should I weigh ?
Weight Limit – The New and Improved BMI?  
by George Fernandez
Background information
  • The WHO defines overweight as a body mass index (BMI) equal to or more than 25, and obesity as a BMI equal to or more than 30.
  • BMI is a simple index of weight-for-height that is commonly used in classifying overweight and obesity in adult populations.
  • BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults.
  • It is defined as the weight in kilograms divided by the square of the height in meters (kg/m 2) and it the most widely used and universally accepted index in the weight management programs.


  • Because BMI measurement is based on metric scale, it is not easy to compute and therefore, special charts, table, special devices such as rotating wheels, and internet tools are used.
  • Also, the meaning of BMI is difficult to grasp by the common individual and therefore the concept of "ideal weight" , "perfect weight", and "healthy weight" are introduced in the weight management programs by translating the BMI ranges.
  • However, most of the individuals having weight issues are not considering themselves as "Ideal individuals" and therefore they don’t take the ideal weight as serious bench mark.
  • Furthermore, the goal of maintaining the ‘healthy weight’ is also problematic for individuals less than 50 years old since maintaining health is not usually a major priority for younger adults.


    A new practical and a common sense weight management index, Max Weight Limit for both male female adults (20-75 years) based on the individual’s height is proposed by Professor George Fernandez, Senior Analytical Consultant SAS Education. .
  • After performing several simulation studies using advanced analytic and graphical features of SAS software, Dr. Fernandez came out with the new practical and commonsense alternative weight management index, Max Weight Limit.
  • A ordinary adult can easily understand Max Weight Limit concept and it can be manually computed by a middle school student.Therefore, using this Max Weight Limit index each adult can start their weight management program as a life long goal starting from age 20.
  • Individualized weight limit we can’t go over, just like a speed limit
  • Max-Weight-Limits correspond very closely to BMIs of 25.5 for men and 24.5 for women
  • Very closely corresponds to weight recommendations listed on BMI charts.
  • Knowledge of your BMI is not required to calculate your Max-Weight-Limit
  • No need to use a chart or online calculator to figure out your Max-Weight-Limit
  • Prevent Obesity and Overweight. Know your MWL  once you reach your maximum height. Make sure to maintain your body weight under your established MWL.
