There is an epidemic of Childhood obesity in the world

From 1963-91 -Doubling of the incidence of children with BMI of more than 95th centile

Overall scales are going up. Children with the same BMI centiles are now heavier

Genetic shift unlikely. Profound environmental effect

Weight centile alone is useless as it does not consider height

Height for weight is better but does not differentiate between increased muscle or fat

BMI reflects the degree of fat content best

BMI = Weight in Kgs / Height in m 2

Obesity is not overweight.

Obesity is excess body fat

In adults

BMI > 25 is overweight

BMI > 30 is obese

In children

BMI > 85 centile for the age is overweight

BMI > 95 centile is obese

Bioelectric impedence

Not useful in clinical practice

Country specific BMI charts Should be prepared and then 85 and 95

Definition and EpidemiologyDefinition and Epidemiology

Increased prevalence is now seen in countries where the major problem used to be malnutrition

Now obesity is caused by poor food choice and decreased activity

Indeed we are seeing this more and more commonly in urban areas in India !

Tracking of ObesityTracking of Obesity Three crucial periods determine the

chance of obesity during adulthood Gestational period – Infant’s of Diabetic

Mother’s have higher chance of becoming obese at 6-10 years and persist into adulthood

Adiposity rebound - Early adiposity rebound was related to parental obesity and persistence of obesity in adulthood

Adolescent period

Childhood onset obesity

Has worse prognosis than adult onset obesity

Associated with

High BP

Increased risk of cardiovascular morbidity

Insulin resistance and dyslipidemia

Lipid profile reveals

High triglyceride levels

Low HDL levels

Visceral fat is most metabolically active

Intensive Diet Intensive Diet Calorie intake 2400 to 2940 KJ per day

Aim is to induce a weight loss of 0.5 kg per week

Protein sparing modified fast (PSMF)

2520-3360 KJ/day

1.5 -2.5 g/kg of IBW / day of high quality protein

Carbohydrate 20-40 gms/day

Does not lead to cardiac arrhythmia as was observed earlier

Page 18: Childhood Obesity

Not prescribed for more than 12 weeks

Risks:

Cholelithiasis, hyperuricemia, hypoproteinemia, orhthostatic hypotension, halitosis, diarrhea

PSMF produce rapid weight loss in the short term

In the long term does not seem to be superior to restrictive diet programmes

LeptinLeptin A hormone secreted by adipocytes in relation

to lipid content

It is a peripheral signal to the hypothalamus of inadequate food intake but NOT of Satiety

Leptin deficiency causing obesity is VERY VERY RARE

Leptin therapy to Leptin sufficient adults is not very impressive in terms of weight loss

No studies in children are available

MetforminMetformin Stops hepatic glucose production

Reduces insulin resistance

Several studies have shown impressive weight reduction in dosages varying from 500 mg to 2 gm per day in children of 8 - 14 years

Side effects

Nausea, flatulence, bloating

Diarrhea, Vitamin B12 deficiency

Lactic Acidosis - Rare

Post op complications are many (8.5%)

Post op mortality is 1.5%

In a recent study by Strauss - Adolescents were treated with bariatric surgery

90% lost > 30 kgs and co morbid conditions improved

Complications include iron deficiency, folate deficiency, small bowel obstruction

Page 26: Childhood Obesity

This is the only treatment with evidence that it can induce sustained significant weight reduction in adolescents who have severe obesity

Can only be recommended to those with highest morbidity

As Strauss concluded: “Gastric bypass remains a last resort option for severely obese adolescents”

Education and awareness programs for parents are required to prevent adolescent obesity

At risk individuals can be identified with BMI curve

The mainstay of treatment is diet, exercise and behaviour modification

At present no medicine is routinely used in clinical practice to prevent or treat obesity
