12.1 Medical and Occupational Life Risk Assessment

Study Focus

Underwriting addresses selection and equitable pricing of life risks. Health, lifestyle, occupation and avocations can affect risk assessment.

Life Underwriting: Physical, Medical, and Financial Assessment

In the life insurance industry, underwriting is the rigorous process of assessing, selecting, and classifying prospective risks to determine whether an application should be accepted, on what terms, and at what premium rate. Because life insurance contracts are long-term, unilateral agreements that may remain in force for several decades, accurate and equitable underwriting is vital to the financial stability of the insurer and the collective security of all participating policyholders.

In Malaysia, life insurers operate under the statutory oversight of Bank Negara Malaysia (BNM) and the legal framework established by the Financial Services Act 2013 (FSA 2013). Intermediaries preparing for the Pre-Contract Examination for Insurance Agents (PCEIA) must understand the fundamental objectives of life underwriting, the dimensions of physical, medical, and financial risk assessment, the sources of underwriting information, and the precise rating remedies used to manage impaired risks.

The Core Purpose of Life Underwriting

Life underwriting serves three paramount objectives in actuarial and insurance practice:

1. Preventing Adverse Selection (Anti-Selection)

Adverse selection (or anti-selection) is the inherent tendency of individuals who possess a higher-than-average probability of suffering loss or premature death to apply for insurance coverage, or seek larger amounts of insurance, compared to individuals with average or favorable risks.

For example, an individual who experiences persistent chest pains or is aware of a strong family history of early heart disease has a far greater personal motivation to purchase a large life insurance policy than a healthy marathon runner. If an insurer were to accept all applicants indiscriminately without medical or financial scrutiny, the proportion of unhealthy individuals entering the risk pool would steadily increase. This would cause mortality claims to exceed actuarial projections, exhausting the common life fund and necessitating steep premium hikes on surviving policyholders.

2. Ensuring Equitable Premium Pricing

Insurance is founded on the concept of mutual risk pooling, where the losses of the few are shared by the contributions of the many. For the pool to operate fairly, risk equity must be maintained: each policyholder must contribute a premium that is directly proportionate to the level of risk they introduce to the pool. Standard lives must not be forced to subsidize the elevated mortality risks of substandard lives. Underwriting guarantees that standard lives pay standard rates, while individuals presenting elevated risks pay commensurate extra premiums or accept modified coverage terms.

3. Safeguarding Insurer Solvency

Under BNM's Risk-Based Capital (RBC) Framework, life insurers must maintain adequate capital reserves to honor all future policy obligations. Deficient underwriting leads to unprojected claims volatility, eroding capital reserves and jeopardizing the insurer's long-term solvency.

Dimensions of Risk Assessment: Physical and Medical Underwriting

Physical and medical underwriting assesses the biological, physiological, and lifestyle factors that directly influence an individual's expected lifespan and susceptibility to debilitating disease.

1. Age and Biological Sex

• Age: Mortality risk increases steadily and exponentially with advancing age. Insurers calculate premiums based on the applicant's age at policy entry, traditionally using Age Next Birthday (ANB) or Age Last Birthday (ALB) as stipulated in the company's actuarial tariff.
• Biological Sex: Actuarial mortality statistics in Malaysia consistently show that females have a longer life expectancy than males across all age brackets. Consequently, life insurance mortality rates are generally lower for females of the same age, whereas female morbidity rates for specific critical illnesses (such as breast or cervical conditions) may require distinct evaluation.

2. Physical Build and Body Mass Index (BMI)

An applicant's physical build is evaluated by measuring height, weight, and abdominal circumference to calculate the Body Mass Index (BMI):

$$\text{BMI} = \frac{\text{Weight in kilograms}}{(\text{Height in meters})^2}$$

• Normal Range (18.5 – 24.9 kg/m²): Accepted at standard rates, assuming all other health indicators are favorable.
• Overweight and Obesity (BMI > 25.0 kg/m²): Moderate to severe obesity (BMI exceeding 30.0 kg/m²) significantly increases mortality risk due to its strong association with cardiovascular diseases, hypertension, Type 2 diabetes mellitus, obstructive sleep apnea, and osteoarthritis. Underwriters apply percentage loadings based on calibrated build charts.
• Severe Underweight (BMI < 17.5 kg/m²): Underweight builds may signal underlying chronic wasting diseases, severe malnutrition, eating disorders, or undiagnosed pulmonary conditions such as tuberculosis.

3. Personal Medical History

Underwriters review an applicant's complete medical history to evaluate past illnesses, surgeries, hospitalizations, and chronic conditions. Key categories include:

• Cardiovascular Disorders: Uncontrolled hypertension, ischemic heart disease, angina pectoris, prior myocardial infarction, valvular disorders, and elevated lipid profiles.
• Metabolic and Endocrine Conditions: Diabetes mellitus (Type 1 or Type 2). Underwriters scrutinize glycemic control using Glycated Hemoglobin (HbA1c) levels. Well-controlled diabetics with no target organ damage may be accepted with a percentage loading, whereas uncontrolled diabetics with nephropathy or retinopathy are generally declined.
• Oncology (Cancer): History of malignant tumors, staging, histopathology grading, completed treatment protocols (chemotherapy, radiation, surgery), and duration of disease-free remission.
• Respiratory, Renal, and Hepatic Diseases: Chronic obstructive pulmonary disease (COPD), severe asthma, chronic kidney disease (elevated serum creatinine or proteinuria), and liver disorders (Hepatitis B or C carrier status, elevated liver enzymes).

4. Family Medical History

Family history provides critical insight into genetic and hereditary predispositions. Underwriters focus specifically on first-degree relatives (parents and biological siblings).

A family history of the following conditions diagnosed or causing death before the age of 60 represents a significant underwriting hazard:

• Early coronary artery disease or sudden cardiac death
• Stroke and cerebrovascular accidents
• Hereditary cancers (such as familial breast, ovarian, or colorectal cancers)
• Polycystic kidney disease
• Huntington's chorea and hereditary neurological disorders
• Familial hypercholesterolemia

5. Lifestyle Habits: Tobacco, Alcohol, and Substance Use

• Tobacco Use: Nicotine and combustion toxins accelerate atherosclerosis and increase the incidence of lung cancer, stroke, and chronic respiratory illness. Malaysian life insurers classify applicants into Smoker and Non-Smoker categories. Non-smoker premium discounts require complete abstinence from all tobacco products, cigarettes, cigars, pipes, and electronic vaping devices for at least 12 consecutive months prior to application. Underwriters frequently verify declarations through urine cotinine lab tests.
• Alcohol Consumption: Evaluated based on weekly units, frequency, and pattern (social drinking vs. heavy or binge drinking). Excessive intake signals liver cirrhosis, pancreatitis, hypertension, and behavioral mortality risks.
• Substance and Narcotics Abuse: Current or recent non-prescription use of narcotics, stimulants, or illicit drugs results in immediate rejection (declined risk).

6. Occupational Hazard Classes

An applicant's daily employment exposes them to varying degrees of accident, physical injury, environmental toxicity, and occupational disease. The Malaysian insurance market categorizes occupations into four distinct underwriting classes:

The following is an illustrative classification, not a uniform Malaysian regulatory table. An insurer may use different classes and decide separately for life, TPD and accident riders.

7. Avocations and Hazardous Hobbies

Recreational activities that carry elevated mortality risks—such as deep-sea scuba diving (exceeding 30 meters or cave diving), private aviation/piloting, mountaineering and rock climbing, motor vehicle racing, skydiving, and paragliding—require specialized questionnaires. Underwriters may impose a flat extra premium or insert a specific exclusion endorsement that relieves the insurer of liability if death or disability occurs while participating in that specific avocation.
