30. RISK FACTORS:
ο’ Crucial periods
ο prenatal period
ο age 5 β 7 years
ο adolescence.
ο’ The point of lowest level of BMI around 6 years
after which it starts increasing is known as adiposity
rebound.
32. ο’ Early feeding practices: Lack of breastfeeding,
increased formula feeds, complementary feeding
before 4 months
ο’ Demographic: parental overweight, low parental
education
ο’ Medication: Antipsychotics ( olanzapine,
resperidone), Antiepiletics (Carbamazepine,
Valproate), Steroids
33. ο’ Dietary: increased junk food, sweetened
beverages, less fibre in diet
ο’ Life style: More screen time, lack of physical
activity, irregular sleep
34. CLASSIFICATION:
ο’ Primary/ Constitutional Obesity: No secondary
cause (>95% cases)
ο’ Secondary/ Organic/ Exogenous obesity:
ο Genetic Syndromes: Prader willi, Downβs,
Bradet-Biedl, Cohen, Carpenter
ο Hypothalamic: Infectious (TBM, Post meningitic
sequelae), ICSOL, Radiation, Surgery, Head
trauma, Hypothalamic Hamartoma
35. ο’ Prader willi syndrome:
ο Short Stature
ο Mental Retardation
ο Hypogonadism
ο Hypotonia
ο Failure To Thrive
41. COMPLICATIONS:
System In Childhood In adulthood
Metabolic Insulin Resistance,
dyslipidemia, metabolic
syndrome
Type 2 diabetes, metabolic
syndrome
Cardiovascular Hypertension Atherosclerosis, LVH,
hypertension
Respiratory Sleep abnormalities, asthma
Musculoskeletal Tibia vara, slipped capital
femoral epiphysis, flat feet
Osteopenia
Gastrointestinal GERD, NAFLD NAFLD, hernia,
cholelithiasis
Endocrine Early puberty, PCOS Type 2 Diabetes
Psychosocial Low self esteem, depression, anxiety, worsening school
performance, social isolation
Dermatological Cellulitis, acanthosis nigricans, carbuncles, intertrigo
Miscellaneous Raised CRP, pseudotumor cerebri, meralgia paresthetica
42. EVALUATION:
ο’ Main aim is to ascertain whether primary or
secondary obesity.
ο’ History:
ο Antenatal history
ο Birth weight
ο Weight gain
ο Sleep pattern
ο Family history
ο Medications
ο Developmental assessment
ο Menstrual history.
43. ο’ Examination:
ο General and systemic examination
ο Anthropometry
ο Blood Pressure
ο Acanthosis nigricans
ο Acne
ο Hirsutism
ο Hair fall
ο Dysmorphic facies
ο Pubertal status
ο Psychiatric evaluation.
44. ο’ Investigations: Routine +
ο Lipid profile
ο Glucose tolerance test
ο Thyroid function
ο Gonadal axis β serum LH, FSH, testosterone
ο Bone age assessment
ο Growth hormone
ο Serum Parathyroid/ Vitamin D
ο Serum insulin, Glycosylated Hemoglobin
(HbA1C)
45. MANAGAMENT:
ο’ Multidisciplinary approach
ο’ Non β pharmacological:
ο Dietary:
of total calories:
ο’ Carbohydrate 45 β 65 %
ο’ Protein 10 β 20%
ο’ Fat 30 β 40%
ο Weight monitoring:
ο’ β€ 11years= 0.5kg/month
ο’ >11 years 1 kg/week
47. ο’ Pharmacological:
ο Antiobesity drugs still being evaluated in children.
ο Advised only in children >16 years with obesity related
complications.
ο Only drug approved is Orlistat.
ο’ Can be used in β₯12 years
ο’ 120 mg TDS with each meal or within 1 hour
ο’ Same as adult
52. PREVENTION:
ο’ Diet:
ο Exclusive breast feeding
ο Timely complementary feeding
ο Healthy feeding practices
ο No fat restriction to be done in infants < 2 years
ο For > 2yr, fat contributes 20 β 30 % of calories
ο Fiber in diet = age + 5g
53. ο Traffic light diet approach:
ο’ Green (go) - fruits and vegetables
ο’ Yellow (caution) - grains and processed meat
ο’ Red (stop) - sweetened and dried fruits, fried foods
ο Proper guidance for age appropriate foods
ο Skipping breakfast, frequent snacking and eating
out to be avoided
54.
55. ο’ Lifestyle
and
physical activity:
ο No TV for < 2 years
ο > 2 years not >2hr/day
ο Young child and toddler daily Β½ to 1 hr of outdoor
activity
ο Older child vigorous exercise for 60min/day
56. ο’ Behaviour:
ο Parental motivation
and commitment
ο No stacking of unhealthy food in house
ο Setting realistic goals for exercise
ο Positive reinforcement
ο Timely monitoring.
57.
58.
59. ENDING CHILDHOOD OBESITY (ECHO)-
WHO COMMISSION:
ο’ Goals:
ο Provide policy recommendations to governments to
prevent infants, children and adolescents from
developing obesity and to identify and treat pre existing
obesity in children and adolescents.
ο To reduce the risk of morbidity and mortality due to non-
communicable diseases, lessen the negative
psychosocial effects of obesity both in childhood and
adulthood and reduce the risk of the next generation
developing obesity.
