What We Will Cover (And Why) Northwestern Mutual 2011 underwriting decisions on juvenile applicants age 10 and younger: • Asthma - #1 • Attention Deficit/Hyperactivity Disorder (ADHD) - #2 • BMI - #3 Actually “Unknown/Other” was #2 and “Blank” was #3 so I consider myself lucky! LCN-823546-022114
Asthma • Asthma is a chronic disease of the airways characterized by periods of reversible airflow obstruction • These periods constitute asthma attacks or exacerbations • Airway inflammation and hyper-reactivity are the factors leading to obstruction • Exposure that provoke attacks include exercise; airway infections; airborne allergens (including dust mites) and airborne irritants including cigarette smoke • LCN-823546-022114
Airway Changes During Asthma Attack During an asthma attack, the smooth muscle layer goes into spasm, narrowing the airway. The middle layer swells because of inflammation, and more mucus is produced. In some segments of the airway, mucus forms plugs that nearly or completely block the airway.

Underwriting Asthma – Mortality Factors • LCN-823546-022114 • Those with frequent and severe asthma symptoms and evidence of airflow limitation are at greatest risk (although sporadic deaths occur in mild, moderate and severe asthma) • In US asthma fatalities are most common in lower income, non-white urban populations • Two clinicopathophysiologic profiles exist: 1) Slow onset fatal asthma (80-85% of cases) with progressive symptoms for more than 12 hours and often up to 1-3 weeks 2) Rapid onset fatal asthma with death occurring 2 to 6 hours after symptom onset
Fatal Asthma Risk Factors Major: • Recent history of poorly controlled asthma • Prior history of near-fatal asthma Minor: • Aeroallergens • Aspirin and NSAIDS • Exercise • Genetic Factors • Illicit drugs • Menstruation • Respiratory viruses • Smoking • ‘Others’ • LCN-823546-022114
Fatal Asthma – Objective Measures • A low FEV1 is associated with an increased risk of asthma exacerbations, and the lower it is the greater the risk (Osborne et al Chest 2007;132:1151 and others) • In a prospective study of severe/difficult to control asthma post-bronchodilator FVC < 70% was a predictor of asthma related ED visits and hospitalization (Miller et al Eur Resp J 2006;28:1145) • Despite this individuals with fatal or near-fatal asthma may have entirely normal baseline spirometry • LCN-823546-022114
Asthma Deaths by Age CDC, MMWR, May 4, 2012 /61(17);315 • LCN-823546-022114
Underwriting Asthma – Practical Approach • Factors associated with persistence of asthma into adulthood include severity, atopic conditions (allergic rhinitis, eczema), positive family history and early age of onset (age 5 or under) • Would use caution and likely decline coverage to young asthmatic children (< 5 years old) with anything but the most mild, intermittent asthma (such as occasional wheezing with colds) • Older children and adolescents who develop asthma after age 5 and who are on inhalers only, with good follow up and no hospitalizations due to their asthma are likely insurable at standard or low substandard rates • LCN-823546-022114
ADHD • ADHD is not new; enhanced awareness due to rapidly advancing research may make it seem like it is • Prevalence in US in children is 3-7%. It is associated with psychiatric co-morbidity in approximately 50-60% of cases (learning disorders, depression, anxiety and antisocial personality disorder among others) • Name is misleading; problem is not lack of attention but rather too much attention to non-relevant stimuli • 3 basic forms listed in DSM IV: Attentional; Hyperactive/Impulsive and Combined • ‘Executive Functioning’ is disturbed by the neurotransmitter imbalance of ADHD; among the areas most commonly distorted are flexibility, organization and planning LCN-823546-022114
ADHD • LCN-823546-022114 • Executive function is a major task of the frontal lobes • Functional MRI studies support decreased activation of areas of frontal lobe during certain tasks in children with ADHD • A 10-year study by NIMH demonstrated that brains of children and adolescents are 3-4% smaller than those of children without disorder • Catecholamines are the main neurotransmitters in frontal lobe, and the main targets for medication used to treat the disorder
ADHD – Persistence in Adults • World health organization study of children with ADHD in 10 countries (Lara et al Biol Psychiatry 2009 Jan 1;65(1):46-54) • An average of 50% of children with ADHD continued to meet DSM-IV criteria as adults • Persistence was related to: Symptom profile – attentional plus hyperactive/inattentive (OR* = 12.4) Symptom severity (OR = 2.0) Co-morbid major depressive disorder (OR = 2.2) High co-morbidity (> 3 child/adolescent disorders in addition to ADHD) (OR = 1.7) Paternal (but not maternal) anxiety mood disorder (OR = 2.4) Parental antisocial personality disorder (OR = 2.2) *OR = Odds Ratio, the odds that an outcome will occur given a particular exposure compared to the odds of the outcome occurring in the absence of the exposure • LCN-823546-022114
Underwriting ADHD – Mortality Factors • There is no clear correlation between ADHD itself and increased mortality • ADHD is a risk factor for developing conduct disorders, oppositional-defiant behavior and substance abuse – presence of any of these increases risk • Suicide risk is increased through worsening of comorbid conditions such as conduct disorder and depression • Adolescent risk-taking behavior may persist into adulthood • Medication for ADHD – What is Risk? • LCN-823546-022114
ADHD Treatment Risks • One often sees articles in the popular press regarding the ‘dangers’ of stimulant medication for ADHD • 1999 study published in ‘Pediatrics’ found that pharmacologic treatment of adolescents with ADHD was associated with an 85% reduction in risk for substance abuse • This is an important fact to keep in mind when considering the inherent risk of medications themselves • In 2011 the FDA released a ‘safety update’ indicating that a large study of children with ADHD treated with stimulant medication did NOT have an increase in adverse cardiac events • There is a ‘black-box’ warning for Strattera (a non-stimulant ADHD drug) regarding increased suicide risk • LCN-823546-022114
Underwriting ADHD – Practical Approach • Since the presence of conduct disorder or oppositional-defiant behavior, as well as substance abuse, are the main factors associated with increased mortality, would use caution in underwriting pre-adolescents with ADHD • The adolescent with ADHD who has no evidence of conduct disorder, oppositional-defiant behavior or substance abuse, and who is compliant with medication and follow up visits, is likely a standard risk • The presence of other psychiatric disorders or neurologic issues will add co-morbidity and increase mortality, and may require an additional rating depending on type and severity • LCN-823546-022114
Childhood Obesity • The term ‘obesity’ wasn’t as well defined in pediatric literature until recently; it was usually used interchangeably with overweight • Obesity now defined as > 95th% of BMI-for-age in 2-19 year olds; overweight is 85-94th% • In children < 2 years old overweight is weight-for-length at or above 95th% • LCN-823546-022114

Do obese children become obese adults? • The evidence would strongly suggest that the answer is YES • Serial data from NHANES (National Health Examination Survey) shows that the increasing prevalence of obesity/overweight in adults is matched by similar trends among children and adolescents • The correlation is higher in obese adolescents but is present at younger ages and lower BMIs as well • LCN-823546-022114
Childhood Obesity – Comorbidities • Hypertension • DM • Fatty liver • Sleep Apnea • PCOS • Pseudotumor cerebri • Orthopedic issues • LCN-823546-022114
Pediatric Obesity – Adult Risks • Overweight/obese children and adolescents who do not develop hypertension or DM are at risk of developing these as adults • The risk of adult co-morbidities is increased in obese adolescents even if the obesity does not persist (Must, et al NEJM 1992:327:1350-5) • Abdominal obesity leads to insulin resistance which leads to metabolic syndrome • Hypertension, lipid abnormalities, DM and CAD are consequences of metabolic syndrome • LCN-823546-022114
Childhood Obesity and Cancer • Studies have shown an increase in certain cancers with as little as an increase of BMI of 5 (Biro & Wien Am J Clin Nutr 2010;91(suppl):1499S-1505S) • Men – Esophageal cancer (RR* = 1.52) Thyroid cancer (RR = 1.33) Colon cancer (RR = 1.24) Renal cancer (RR = 1.24) • Women – Endometrial cancer (RR = 1.59) Gallbladder cancer (RR = 1.59) Esophageal cancer (RR = 1.51) Renal cancer (RR = 1.34) *RR = Relative Risk, a measure of the risk of a certain event happening in one group compared to the risk of the same event in another group • LCN-823546-022114
Childhood Obesity and Cancer • Several factors thought to be at play in terms of the increased cancer risk • Dietary – Increased fats, decreased fruits/vegetables • Decreased activity levels • Decreased Vitamin D levels • LCN-823546-022114
Childhood Obesity - Prevention • Primary prevention through lifestyle and environmental interventions is considered the best approach for addressing worldwide cancer risk (Danaei et al Lancet 2005;366:1784-93) and may be best approach to obesity epidemic as well • Health care providers need to address this in a fashion that does not encourage eating disorders (Patton et al BMJ 1999;318:765-8) • Comprehensive programs that promote increased activity and decreased television viewing time are helpful • School programs that promote increased physical activity and improve diet behaviors can be successful (Brown et al Obes Rev 2007;8:127-30) • Parental involvement! • LCN-823546-022114
Childhood Obesity – Practical Approach • In his 2008 article in JIM Dr. Dan Zimmerman of Northwestern Mutual concludes that “pediatric overweight adversely affects mortality rates; the exact extent and degree have yet to be determined” (J Insur Med 2008;40:204-209) • Although it is now 5 years later, we do not yet have all the answers • Seems safe to say that one needs to be very cautious in underwriting overweight children and especially adolescents; those who qualify as ‘obese’ are most likely uninsurable due to the significant future mortality risk to which they are subject • LCN-823546-022114
