Why Healthspan Intelligence Looks at 13 Key Areas of Your Health

❤️1. Heart & Vessels

Protecting your heart and blood vessels starts with understanding factors that influence their health. Blood pressure, cholesterol, tobacco exposure, and blood sugar offer different, useful pieces of that picture.^[2]

Blood pressure measures the force of blood against artery walls. LDL cholesterol is one part of a blood cholesterol report. Together, these readings help make a discussion about cardiovascular health more specific.

They describe risk factors rather than the full condition of your heart or every blood vessel. The System’s score is not an estimate of your total cardiovascular risk.

🔥2. Metabolic Control

Blood sugar measurements help you understand how your body manages glucose and whether a result needs attention. A glucose test gives a reading at a particular time. The HbA1c test, often called A1C, reflects average blood sugar over roughly three months.^[3]

The two offer different views: one captures a moment, while the other helps describe the longer pattern. A1C does not show short-term rises and drops, and some health conditions affect its accuracy. Diagnosis and treatment matter when interpreting either result. A lower number is not automatically the right goal for everyone.^[3]

🫘3. Kidney Health

Your kidneys filter your blood. Looking at both filtration and possible damage gives a more useful picture of kidney health than either measurement alone.^[4]

Estimated glomerular filtration rate, or eGFR, estimates how well the kidneys filter. The urine albumin-to-creatinine ratio, or uACR, checks for a protein called albumin in urine. Albumin in urine can be a sign of kidney damage. These tests answer different questions, so one does not replace the other.^[4]

An unusual result may need to be repeated and interpreted in context. A single result cannot establish a lasting kidney condition. An abnormal finding still deserves attention when the other test is missing.^{[4] [5]}

🫁4. Aerobic Reserve

Endurance helps you keep going during a sustained walk or other physical activity. The related term cardiorespiratory fitness describes how well your heart, lungs, and circulation support that effort. Assessing fitness adds information beyond common risk factors.^[6]

An exercise test can measure oxygen use, reported as VO₂. That gives information about your response to exercise. Reported activity minutes answer a different question: how much activity is part of your routine.

Both are useful, but activity habits are not a direct measurement of fitness. A fitness result also cannot establish that every kind of exercise is suitable for you.^[6]

💪5. Muscle & Strength

Strength supports everyday tasks such as carrying groceries and getting out of a chair. Measuring grip strength or timing five chair rises without using your arms gives practical information about strength-related physical function. Clinicians use these tests to help identify low muscle strength.^[7]

Grip is a useful indicator, rather than a direct measurement of every muscle. Chair rises require endurance as well as strength. Using the appropriate test method makes the result easier to interpret.^[7] Training frequency describes a habit, not measured strength.

🚶6. Mobility & Balance

Getting up, walking, turning, and staying steady help you move through daily life. Testing these abilities makes it possible to describe a difficulty more precisely. Timed Up & Go involves standing, walking, turning, and sitting. A heel-to-toe standing test looks at balance.^[8]

Fall history adds information about what happens outside a test. Doing well on one task cannot guarantee that you will not fall. Falls, concerning results, or being unable to complete a test safely can be reasons for follow-up.

🦴7. Bone & Fracture Resilience

A broken bone can interrupt daily life and affect independence. A bone-density scan called DXA measures the amount of mineral in bone. It contributes to assessing fracture risk when considered alongside age, previous fractures, and other factors.^[9]

Its value lies in adding measured information to that broader assessment. Bone density alone cannot tell you whether a bone will break. The full report and your circumstances determine how to interpret the result and whether testing is appropriate.^[9]

⚖️8. Body Composition

Weight, height, and waist size offer complementary clues about body size and related health risks. Waist size adds information about fat carried around the abdomen that weight alone does not describe.^{[10] [11]}

Body mass index, or BMI, relates weight to height. Comparing waist size with height can add context when that measure is applicable.^[16] These are indirect indicators, not direct measurements of body fat or muscle. BMI cannot distinguish muscle from fat or bone. That is why a lower number is not always better.^[10]

😴9. Sleep & Recovery

Sleep supports alertness, clear thinking, and everyday activities. Looking at duration together with how rested you feel and how often you wake gives a fuller description than hours alone.^[12]

Questions about sleep and a simple diary can make patterns easier to discuss with a health professional. Enough hours do not explain why you might still wake tired. These records cannot diagnose a sleep disorder or prove that sleep is helping you recover. Daytime sleepiness, breathing concerns, and persistent problems need attention in their own right.

🥗10. Nutritional Resilience

Eating well depends on both food choices and being able to eat enough. Appetite, access to meals, food preparation, and chewing or swallowing difficulties can all affect whether eating meets your needs.^[13]

Questions about vegetables and fruit, beans, nuts, seeds, and other foods describe your usual eating pattern. Questions about barriers help explain what may make that pattern difficult to sustain. Changes in intake, swallowing, or unintended weight loss also matter in a clinical nutrition assessment.^[17]

This information can guide a useful discussion, but a questionnaire does not measure nutrient levels or establish that every need is met. Favorable food choices do not cancel a concern about eating difficulties or unintended weight loss.

🧠11. Cognitive Capacity

Thinking and remembering support familiar tasks, from managing a schedule to following a conversation. The World Health Organization includes cognition in its approach to health in older age.^[14]

Noticing what has changed—and how it affects daily life—makes a healthcare discussion more useful. Your own observations and concerns raised by someone who knows you both matter. One concerning change can be enough to discuss with a health professional.^[18]

These observations describe experience rather than performance on a clinical test. Self-reported answers cannot diagnose or rule out dementia.

👁️12. Sensory Capacity

Hearing and vision help you follow a conversation, read a message, and take part in daily life. The World Health Organization includes both in its approach to care for older adults.^[14]

Describing difficulties while using your usual hearing support, glasses, or contacts shows how well those supports meet everyday needs. Hearing and vision deserve separate attention because a useful result in one says little about the other.

Reports of daily function complement professional assessment. They do not replace a hearing assessment or eye examination, and managing daily tasks does not establish normal test results.

🤝13. Psychological & Social Resilience

Connection and support are important parts of health and daily life. Social isolation means having few social contacts; loneliness is the feeling of being alone or disconnected. Both can affect physical and mental health and quality of life.^[15]

Questions about loneliness, available help, stress, mood, purpose, and valued activities help identify what kind of support may be useful. They bring personal circumstances into a profile that would otherwise rely heavily on measurements.

A brief set of answers cannot capture someone’s full circumstances or diagnose a mental health condition. Needing support is not a personal failure.
