Childhood Obesity and Physical Therapy

Number of pediatric PT patients with obesity has increased in recent years.

According to the CDC, the childhood obesity rate has tripled in the last 30 years.

In 2010, 17% of American children and adolescents 2-19 years of age were reported to be obese.(1)

This is due to: Shifting dietary patterns Sedentary activities instead of active play. Childhood orthopedic injuries due to excess weight.

Etiology

Obesity is the accumulation of excess body fat. BMI greater than 30 kg/m^2 >25kg/m^2 is considered overweight

Positive energy balance is typically the cause. More calories taken in than are expended

(2)

Biological FactorsA child’s genetics “load the gun” but their environment “pulls the trigger”.

The patient’s past medical history should include these information points to help determine the cause of excessive weight gain: “Obesogenic”

A new term for certain genetic traits that predispose someone to gain weight. (4) Birth Weight Infant Feeding:

Formula vs Breast Milk Adiposity Rebound:

Lowest BMI should be at 5-6 years old before gaining body fat again into adulthood.

If the child did not have an adiposity rebound or it was not at age 5-6 this may point to other homeostatic imbalances.

Sexual Maturation: Body fat total, distribution, and percentage are associated with maturation. Heavier female children have earlier onset of menarche. (5)

Environmental Factors

Environment is the more important, and easier to manipulate, factor when treating childhood obesity.

Intake: Energy Density Glycemic Index Vegetables and Fruits Soft Drinks Serving Sizes Meal Frequency, Snacking Habits

Physical Activity: Average amount of time spent walking and bicycling in ages 5-15 dropped 40% from 1977-1995,

mostly due to less children walking/biking to school.(3) Sports PE at School

Free Time: Television Viewing and Computer Games

Parental Obesity and Family Environment: Genetic and Shared Lifestyle

SES: Urban poor at highest risk.

Self Esteem and Quality of Life

Weight Management in Children- Critical Measurements

BMI Body Composition Waist Circumference Physiology:

ICF Model Comorbidities Physical Disabilities Cognitive Disabilities

Psychology: Depressed or Happy Relationships (Children and Parents)

Treatment- What Determines Need for Intervention?

It is our job as PTs to recognize the need for weight loss and educate our patients of potential benefits of weight loss.Increased EnergyLess Functional LimitationsLess Orthopedic ProblemsImproved Self Esteem

TreatmentEach patient’s treatment will be slightly different based off of: BMI: Use Standard Growth Chart

95th percentile OR 85th percentile and presence of Co-morbidities. Presence of co-morbidities:

Diabetes Mellitus Dyslipidemia Hypertension High triglycerides Asthma Menstrual Problems Sleep Apnea

Age: infancy, childhood, adolescence Different energy needs depending on stage of life

Parent’s Weight and Lifestyle: Parent’s play a large role in the success of the intervention

Treatment

(4)

Treatment

Exercise Prescription: Based off initial evaluation Results of submaximal exercise testing and strength testing Goals should be to improve cardiovascular endurance and strength as

appropriate. Focus on fun activities

Weight maintenance in combination with growth in height will lead to decreased BMI over time. (2) Maintain current weight and not gain Supervised exercise first, then home exercise or maintenance program

Lifestyle Modifications Teach positive lifestyle modifications that will last beyond the

PT intervention! Decrease severity of obesity related diseases, functional impairments, and

limitations. Increase self esteem and quality of life

60 Minutes of physical activity per day: Outdoor play Sports team

Referral to a dietician Educate the parents:

Ways to change the family’s diet and activity level. Limit “inactivity” such as TV watching and computer games. Positive reinforcement and goal setting techniques appropriate for weight loss goals.

Example- As a reward for good grades, let the child have an hour at a batting cage or roller skating rink instead of candy or a new video game.

(5)

Discussing the Topic of Weight

Use “people first” language Stress that childhood obesity, if untreated, can lead to:

Life Long Obesity Metabolic Syndrome Cardiovascular Disease Diabetes Renal Failure

Family Education

The family needs to be taught how to create positive changes for the child so their weight loss is maintained

after they are discharged from PT. Dietary:

Meal Planning Availability of healthy snacks Portions

Physical Activity: Encourage active play Limit sedentary activities

Behavioral: Goal Setting Self Monitoring Positive Reinforcement Techniques
