Question

M.R., age 12 years, weighs 26 kg/57 lbs and is 60 in/150 cm tall. She is concerned about her weight but finds it hard to "diet" because her family constantly snacks while watching TV. She enjoys texting friends and using the computer for chats and surfing the latest musical groups. Her father tells her not to

worry about her weight, that men like women with some "meat on their bones." Although she likes swimming, she has stopped going to the local pool since her weight has increased.

1. Why are specific tables used to calculate body mass index in children and adolescents rather than a simple formula of mass divided by height used for adults?

2. What family factors are related to M.R.'s weight?

3. What personal factors are related to M.R.'s weight?

4. M.R. is at high risk of developing metabolic syndrome because of her weight. What potential life-threatening health problems may she experience if she does develop this syndrome?

Answer 1

1. Specific tables are used to calculate body mass index (BMI) in children and adolescents because their body compositions change as they grow and develop. The BMI standards for adults may not be appropriate for children and adolescents because their fat-free body mass and percentage of body fat differ from adults. The BMI of children is also affected by age and gender.

2. The family factors that are related to M.R.'s weight include the constant snacking while watching TV, which may lead to high calorie intake, and her father's comment about preferring women with some "meat on their bones," which can have a negative impact on M.R.'s body image and self-esteem.

3. The personal factors that are related to M.R.'s weight include her sedentary lifestyle of using the computer and texting friends, and her avoidance of swimming due to her weight gain.

4. If M.R. develops metabolic syndrome, which is a cluster of conditions that include high blood pressure, glucose intolerance, and dyslipidemia, she may be at risk of developing cardiovascular disease, type 2 diabetes, stroke, and other life-threatening health problems. It is important that she takes steps to manage her weight and lower her risk of these health problems.
