Unveiling the Healthy Lifestyle Index: Understanding Its Significance and Advantages

Although we now know that unhealthy lifestyle behaviors are associated with an increased risk of various chronic diseases and death, this was not always the case. The first studies to measure this relationship in a standardized way focused on three parameters: following a Mediterranean diet, the number of years practicing the habit of smoking, and body mass index. Since then, throughout this century, experts have worked with multiple indices.

Searching for the ideal index

In May 2024, the group of Iranian scientist Elaheh Dehghani, from the Tehran University of Medical Sciences, selected five tools:

1. Healthy lifestyle questionnaire. It includes a balanced diet, respect for meal times, reduction of tobacco and alcohol consumption, improvement of rest habits and increased physical activity.
2. Adolescent Lifestyle Index. It is based on water consumption, physical activity, sun protection, social relationships, search for clean air, eating habits, risk behaviors and leisure habits.
3. Vegetarian Lifestyle Index. It assesses the consumption of the following dietary components: whole grains, legumes, soy, meat substitutes, vegetables, fruits, nuts and seeds, water, and reliable sources of vitamin B-12. It also takes into account physical activity.
4. Healthy lifestyle questionnaire for breast cancer survivors. Includes dietary habits, environment (e.g., exposure to pollutants), physiology, health-responsible behavior, stress management, social relationships, and spiritual growth.
5. Healthy Lifestyle Index. It takes into account five parameters: smoking, physical activity, diet, alcohol consumption and sleep duration.

Of all these instruments, the last one stands out for its wide applicability and for having been evaluated in multiple studies with diverse populations. It has proven to be useful both in research and in clinical practice to evaluate and improve habits.

One of the first attempts to apply it dates back to 2001. That year, researchers Andrew Steptoe and Jane Wardle, from the Department of Epidemiology and Public Health at University College London, replaced the concept of “factor” with that of “behaviour”.

Steptoe and Wardle thus identified eleven health behaviors for seven activities: regular exercise, alcohol consumption, inclusion of fat in the diet, fiber consumption, adding salt to food, use of seat belts and use of sun protection. These behaviors were used to evaluate the participants’ lifestyle, ranging from 0 (no healthy behaviors) to 11 (all healthy behaviors).

Endorsed by the WHO

Last July, based on the European Prospective Investigation into Cancer and Nutrition (EPIC), the World Health Organization (WHO) issued a document stating that the Healthy Lifestyle Index is capable of measuring the risk of type 2 diabetes, cardiovascular disease, cancer and premature mortality.

The study claims that the index is useful both in its standard form, giving equal weight to each lifestyle component, and in its specific form. In the latter case, the relevance of each item is adjusted according to its relationship to a particular medical condition, such as diabetes, cardiovascular disease or cancer. In this way, the index is more personalized and can offer a more precise assessment for each type of condition.

The authors of the report compared different parameters, such as the risk ratio, a measure that compares the risk of a disease between two groups; Harrell’s C index, which evaluates the ability of a model to correctly predict outcomes; and population attributable fractions, the proportion of cases of a disease that could be avoided if a specific risk factor were eliminated.

Pay attention to the results

The results show that a high value of this index is associated with a lower risk of type 2 diabetes, cardiovascular disease, cancer and premature mortality. The following parameters are assessed:

• SmokingThere are three possibilities: the person being evaluated has never smoked, is an ex-smoker, or currently smokes.
• Alcohol intake. Daily amount consumed.
• Physical activity. Active, moderately active or inactive level.
• Body mass index.
• Feeding. Score based on adherence to the Mediterranean diet.
• Sleep quality. Considered an important factor to evaluate the relationship between lifestyle and health outcomes.

If, as the study indicates, the Healthy Lifestyle Index is a valuable tool for assessing the combined impact of multiple behaviors, it should be used in three strategies:

• Promoting healthy habits: do not smoke, moderate alcohol consumption, follow a balanced diet, engage in regular physical activity and maintain an adequate body weight.
• Implementation of public health policies:The results can guide the formulation of more precise and specific recommendations to prevent chronic diseases.
• Personal evaluation: Any individual and health professionals can use the index as a tool to evaluate and improve lifestyle habits.

The Healthy Lifestyle Index: A Comprehensive Tool for Assessing Chronic Disease Risk

As we navigate the complexities of modern life, it has become increasingly clear that unhealthy lifestyle behaviors are linked to a heightened risk of chronic diseases and premature mortality. In response, experts have developed various indices to measure the relationship between lifestyle choices and health outcomes. This article delves into the evolution of these indices, highlighting the importance of the Healthy Lifestyle Index, its components, and its endorsement by the World Health Organization (WHO).

Searching for the Ideal Index

In the early days of research, three primary parameters were used to assess the relationship between lifestyle and health outcomes: adherence to a Mediterranean diet, years of smoking, and body mass index (BMI). However, as our understanding of the complexities of chronic disease risk has grown, so too has the need for more comprehensive indices. Iranian scientist Elaheh Dehghani and her team recently evaluated five tools, each with its unique focus and components.

Endorsed by the WHO

In July 2024, the WHO issued a report stating that the Healthy Lifestyle Index is capable of measuring the risk of type 2 diabetes, cardiovascular disease, cancer, and premature mortality. This endorsement is significant, as it acknowledges the index’s versatility and effectiveness in evaluating lifestyle behaviors and their impact on health outcomes. The WHO’s recognition of the Healthy Lifestyle Index underscores its potential for widespread adoption in both research and clinical practice.
