Lifestyle Indicators & Guidelines
What Are Lifestyle Indicators?
While physiological indicators measure physical data like heart rate and blood pressure, lifestyle indicators focus on what a person does — their daily choices and behaviours. Health professionals use published guidelines to compare an individual’s lifestyle against recommended standards. The Component 3 specification requires you to know five areas of lifestyle indicators and their associated guidelines.
Lifestyle indicators are important because they reveal the causes behind abnormal physiological readings. If someone has high blood pressure and a high BMI, lifestyle indicators help identify why — perhaps they eat too much salt, do not exercise, and drink excessively. This makes it possible to recommend specific, targeted actions for improvement.
Nutrition — The Eatwell Guide
The Eatwell Guide is the UK government’s visual guide to a healthy, balanced diet. It divides food into five groups and shows the proportions in which they should be eaten.
Fruit and vegetables: Should make up just over a third of the diet. At least 5 portions a day. Provide vitamins, minerals, and fibre.
Starchy carbohydrates: Should make up just over a third of the diet. Includes bread, rice, pasta, and potatoes. Choose wholegrain varieties where possible for more fibre.
Proteins: Includes beans, pulses, fish, eggs, and meat. Aim for two portions of fish per week, one of which should be oily (e.g. salmon, mackerel). Choose lean cuts of meat and eat less processed meat.
Dairy and alternatives: Includes milk, cheese, and yoghurt. Choose lower-fat and lower-sugar options. Provides calcium for strong bones.
Oils and spreads: Needed in small amounts. Choose unsaturated oils (e.g. olive oil, rapeseed oil) rather than saturated fats (e.g. butter, lard).
The Eatwell Guide recommends: at least 5 portions of fruit and vegetables per day, plenty of starchy carbohydrates (preferably wholegrain), some protein and dairy, and small amounts of unsaturated oils. It also advises drinking 6 to 8 glasses of fluid per day and limiting foods high in fat, salt, and sugar.
A health professional would compare an individual’s actual diet against the Eatwell Guide to identify areas for improvement. If someone eats very few vegetables, consumes too many sugary drinks, and regularly eats processed foods high in salt, these lifestyle choices increase their risk of obesity, type 2 diabetes, CVD, and nutrient deficiencies.
Physical Activity — UK CMO Guidelines
The UK Chief Medical Officers’ (CMO) Physical Activity Guidelines set out the recommended levels of exercise for different age groups.
Children and young people (5–18 years): At least 60 minutes of moderate-to-vigorous physical activity every day, including activities that strengthen muscles and bones at least 3 days per week. They should also minimise the amount of time spent being sedentary (sitting for extended periods).
Adults (19–64 years): At least 150 minutes of moderate-intensity activity per week (e.g. brisk walking, cycling) or 75 minutes of vigorous-intensity activity (e.g. running, swimming). Additionally, adults should do strength-building activities on at least 2 days per week and reduce extended sitting time.
Older adults (65+ years): Same targets as adults, with added emphasis on activities that improve balance and coordination to reduce the risk of falls.
If an individual is not meeting these guidelines, they are at increased risk of obesity, cardiovascular disease, type 2 diabetes, osteoporosis, depression, and some cancers. A health professional would assess the person’s current activity levels and recommend realistic ways to increase them.
Smoking — UK CMO Guidelines
The UK CMO’s position on smoking is clear: there is no safe level of smoking. The guidelines recommend complete abstinence — not smoking at all is the only way to avoid the health risks. Even light or occasional smoking increases the risk of lung cancer, heart disease, stroke, and COPD.
The CMO guideline for smoking is that there is no safe level. The only recommendation is to not smoke. For those who currently smoke, the recommendation is to quit completely using available support services such as NHS Smokefree.
Health professionals assess whether an individual smokes, how many cigarettes per day, and for how long. This data helps calculate the level of risk and the urgency of quitting. Support options include nicotine replacement therapy (NRT), prescription medications, counselling, and the NHS Smokefree helpline.
Alcohol — UK CMO Guidelines
The UK CMO Alcohol Guidelines recommend that both men and women should drink no more than 14 units of alcohol per week. These units should be spread over at least 3 days, with several alcohol-free days each week. There is no “safe” level of drinking, but staying within 14 units keeps the health risks low.
One unit of alcohol equals 10ml of pure alcohol. Examples: a single pub measure of spirits (25ml at 40%) = 1 unit; a small glass of wine (125ml at 12%) = 1.5 units; a pint of lower-strength beer (3.6%) = 2 units; a pint of higher-strength beer (5.2%) = 3 units. Many people underestimate how many units they consume because drink sizes and strengths vary. Binge drinking (consuming a large amount in a single session) is particularly harmful, even if the weekly total stays under 14 units.
Exceeding the alcohol guidelines increases the risk of liver disease, heart disease, stroke, some cancers (particularly mouth, throat, and liver), and mental health problems including depression and anxiety. A health professional would assess an individual’s weekly alcohol consumption and compare it against the 14-unit guideline to determine risk level.
Substance Misuse
For substance misuse, there are no “safe level” guidelines because the use of illegal substances like cannabis and opiates carries inherent health and legal risks. Health professionals assess whether an individual uses any substances, the type and frequency of use, and whether there are signs of dependency or addiction.
Key indicators of substance misuse problems include: using substances more frequently or in larger amounts over time, being unable to stop despite wanting to, neglecting responsibilities (work, family, education), needing more of the substance to achieve the same effect (tolerance), and experiencing withdrawal symptoms when not using. If substance misuse is identified, the individual may be referred to specialist services including drug and alcohol support teams, counselling, and rehabilitation programmes.
Lifestyle indicators work alongside physiological indicators to build a complete picture of a person’s health. For example, if an individual has high blood pressure (physiological) and the lifestyle assessment reveals they eat a high-salt diet, drink 25 units of alcohol per week, and do no exercise (lifestyle), the health professional can recommend specific, targeted changes — reduce salt, cut alcohol to 14 units, start gentle exercise. This is far more useful than simply telling the person their blood pressure is too high.
