How Health Risk Is Scored
Scoring Methodology
Each domain is scored 0-100 (higher = healthier):
100 = Optimal health behaviours
70-99 = Good health
50-69 = Average, some risks
Below 50 = Significant risks identified
Overall Score = Weighted average across 8 domains:
Cardiovascular: 25% weight (highest CVD burden)
Metabolic: 20%
Lifestyle: 20%
Cancer/Preventive:10%
Mental Health: 10%
Musculoskeletal: 5%
Respiratory: 5%
Environmental: 5%

Frequently Asked Questions
The health score (0–100) is a weighted composite across 6 domains: Cardiovascular (25%), Metabolic (20%), Lifestyle (20%), Cancer/Preventive (10%), Mental Health (10%), and Musculoskeletal/Respiratory (10%). Each domain contributes to the total based on your specific answers. A score above 75 indicates low overall risk. 60–74 is moderate. 40–59 is elevated. Below 40 is high risk. The score is not a clinical diagnostic - it is a structured tool to identify your highest-priority risk areas and guide conversation with a healthcare professional.
For smokers: quitting smoking has the single largest impact - reducing all-cause mortality risk by 50% within 5 years. For non-smokers: regular physical activity (150+ minutes per week of moderate intensity) is the most powerful single intervention - it reduces cardiovascular disease, type 2 diabetes, depression, cognitive decline, and multiple cancer risks. Diet quality and healthy weight management are third and fourth. Focus on whichever risk factor applies most strongly to you - that's where the marginal gain is highest.
No questionnaire can precisely predict individual health outcomes - human biology is too complex and variable. However, validated assessments like this one identify patterns of risk that correlate with higher disease probability at a population level. The risk factors used here are based on extensive epidemiological research from CDC, WHO, and major clinical guidelines. Use the results as a structured conversation starter with your doctor - not as a diagnosis or prognosis. Your doctor can add clinical measurements (blood pressure, lab values, physical examination) that no questionnaire can capture.
Yes - lifestyle domains can change substantially in weeks to months. Most rapid-impact changes: quitting smoking (measurable cardiovascular improvement begins immediately), increasing physical activity (blood pressure and resting heart rate improve in 3–4 weeks), dietary improvement (blood glucose and LDL cholesterol can improve in 4–8 weeks), improving sleep quality (mental health and metabolic markers respond quickly). Cardiovascular risk from fixed factors (age, family history) does not change, but modifiable lifestyle-related risk can shift meaningfully in 90 days with consistent effort.
The mental health domain screens for: depression and anxiety symptoms (mood, energy, worry, loss of interest), sleep quality (often both a cause and effect of mental health), social connectedness and isolation, stress levels and stress management capacity, and access to mental health support. Mental health is included because it significantly impacts physical health - depression increases cardiovascular risk by 50–100%, impairs immune function, worsens adherence to medication and lifestyle advice, and is associated with shortened life expectancy. These questions are not a clinical depression or anxiety screening - they indicate whether further evaluation with a professional may be beneficial.
For most healthy adults: every 6–12 months is appropriate. After making targeted improvements in a specific area, reassess that domain in 3 months to gauge progress. After a health event - new diagnosis, illness, medication change, significant life stressor - reassess promptly to update your risk profile. Using the assessment periodically over time is more valuable than a single snapshot: trends across multiple assessments show whether your overall health is improving, stable, or declining, which is more informative than any single score.
According to WHO and CDC, the top modifiable risk factors by global disease burden: (1) Tobacco - causes 35% of all cancer deaths. (2) Physical inactivity - contributes to 10% of all deaths globally. (3) Poor diet - associated with 11 million deaths/year. (4) Obesity/overweight - drives cardiovascular disease, diabetes, and 13 cancer types. (5) Excessive alcohol - 3 million deaths/year. (6) High blood pressure - the leading risk factor for cardiovascular disease. Genetics accounts for roughly 25–30% of health outcomes; lifestyle and environment influence the other 70–75%.
Yes - a low score (below 50) or any single domain showing high risk warrants discussion with a healthcare professional. The assessment identifies areas for attention but cannot measure your actual blood pressure, blood glucose, cholesterol, or any clinical marker. A GP can review your full medical history, order relevant tests, and provide context that no questionnaire can. If specific risk factors are flagged - family history of heart disease, BMI above 30, irregular heart rhythm, unexplained weight loss, or persistent mood symptoms - these warrant professional evaluation regardless of your overall score.
Health Risk Assessment - The Eight Domains That Predict Long-Term Health
Medical disclaimer: This health risk assessment is for general educational and awareness purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. Results should not be used to make medical decisions. Consult a qualified healthcare professional for any health concerns or before making significant changes to your health behaviour.
Chronic disease risk is rarely determined by a single factor - it emerges from a pattern of interconnected lifestyle, metabolic, and environmental factors that compound over time. A comprehensive health risk assessment maps this pattern across multiple domains simultaneously, revealing which areas represent the greatest risk and where intervention would have the most impact. This is why general practitioners, occupational health services, and health insurers use structured assessments rather than single-metric tests.
What the score reflects: A score of 75+ indicates low overall risk - most domains are favourable. 60–74 is moderate risk - specific areas need attention. 40–59 is elevated risk - multiple factors require active management. Below 40 is high risk - multiple domains show significant risk factors that strongly warrant medical evaluation.
The Eight Health Domains - What Each One Measures
Core Health Domains
- Cardiovascular (25% of score) - Blood pressure, cholesterol, smoking, family history, exercise. The leading cause of death in most countries.
- Metabolic (20%) - BMI, waist circumference, blood glucose, diabetes risk. Central to chronic disease burden.
- Lifestyle (20%) - Physical activity, diet quality, sleep, alcohol use, stress. The most modifiable domain.
- Cancer/Preventive (10%) - Screening frequency, sun exposure, high-risk habits, family history. Prevention and early detection.
Supporting Health Domains
- Mental Health (10%) - Depression/anxiety symptoms, social connection, stress management. Strongly impacts physical health.
- Musculoskeletal (5%) - Joint pain, mobility, flexibility, occupational ergonomics.
- Respiratory (5%) - Smoking history, environmental exposures, breathlessness, lung-affecting conditions.
- Preventive Care (5%) - Vaccination status, regular check-up frequency, dental health, health literacy.
The Most Impactful Lifestyle Changes - Evidence Ranked
Research consistently identifies a hierarchy of lifestyle interventions by impact on all-cause mortality and disease burden:
- Quitting smoking (if applicable) - The single most impactful change for any smoker. Risk of cardiovascular disease drops by 50% within 1–5 years. Cancer risk gradually normalises over 10–15 years. Life expectancy gain: 10+ years for heavy long-term smokers who quit before 50.
- Regular physical activity - 150 minutes of moderate-intensity aerobic activity per week reduces all-cause mortality by approximately 30–35%. Reduces cardiovascular disease, type 2 diabetes, depression, cognitive decline, and risk of at least 8 types of cancer. Even 15–30 minutes of daily brisk walking substantially benefits sedentary individuals.
- Diet quality - A diet high in whole foods (vegetables, legumes, whole grains, fish) and low in processed foods, red meat, and refined sugars reduces cardiovascular disease and metabolic disease risk. Associated with 11 million premature deaths annually when poor globally.
- Achieving and maintaining healthy weight - Obesity is an independent risk factor for cardiovascular disease, type 2 diabetes, sleep apnea, and multiple cancers. Even a 5–10% reduction in body weight improves metabolic markers meaningfully.
- Regular preventive screening - Blood pressure, cholesterol, blood glucose, cancer screening (mammography, colonoscopy, PSA depending on age and risk) - early detection dramatically changes outcomes for most conditions.
Mental Health and Physical Health - A Two-Way Relationship
Mental health is included in this assessment not as a separate domain but as a genuinely integrated part of physical health risk. The evidence on this connection is robust:
- Depression increases cardiovascular disease risk by 50–100% - comparable to smoking in some studies.
- Chronic stress elevates cortisol, which directly damages arterial walls and suppresses immune function.
- Poor mental health is associated with worse medication adherence, more sedentary behaviour, poorer diet, and more substance use.
- Social isolation is associated with a 29% increase in all-cause mortality - comparable to smoking 15 cigarettes per day in its effect on longevity.
- Conversely, treating depression and anxiety significantly improves adherence to physical health recommendations and outcomes in cardiac patients.
This bidirectional relationship is why the mental health domain is weighted meaningfully in the overall score, and why recommendations in this domain are often the highest-impact changes for people whose physical risks are otherwise managed.
