Abstract
Purpose:
This study aimed to measure healthy lifestyle for European adults.
Design:
Cross-sectional study.
Settings:
In 20 European countries.
Participants:
A total of 34 993 (16 749 men, 18 244 women) European adults.
Measures:
Data were from the 2014 European Social Survey (n = 34 993) on 4 modifiable behaviors (physical activity, fruit and vegetable consumption, not drinking alcohol to excess, and not smoking) as well as sleep quality.
Analysis:
Behaviors were combined and formed a healthy lifestyle measure. Binary logistic regression was done to determine associations of healthy lifestyle and sociodemographic characteristics.
Results:
Only 5.8% of the adults reported a healthy lifestyle. The prevalence of having a healthy lifestyle varied among European countries. The lowest rates were in Hungary (1.3%) and Czech Republic (1.9%). The highest rates were in United Kingdom (8.6%) and Finland (9.2%). Those who presented a higher likelihood of having a healthy lifestyle were middle age (odds ratio [OR] = 1.20), older people (OR = 1.34), having higher household income (OR = 1.33), being a student (OR = 1.38), and retired (OR = 1.31). Those less likely to have a healthy lifestyle were lived without a partner (OR = 0.82), unemployed (OR = 0.73), and lived in rural areas (OR = 0.86).
Conclusions:
Few European adults were practicing 5 healthy behaviors. This should be a message for governments and be considered in the establishment of preventive public policies in the areas of health and health education.
Keywords
Introduction
It is recognized that behaviors are the key determinants of health and that positive changes can reduce rates of chronic disease and improve health outcomes. 1 -3 Some of the most important behaviors associated with health are physical activity, healthy diet, moderate alcohol consumption, and not smoking. 4 -6 Besides these behaviors, sleeping is now considered an important health behavior related to health status. 7,8
A healthy lifestyle should be a combination of behaviors. In the literature, several attempts to measure lifestyle can be found, including at least 3 of the behaviors considered as the most important ones. 9 Research has shown that a healthy lifestyle is associated with better health outcomes and lower mortality rates. 10 -13
Using measures of physical activity, diet, alcohol consumption, and smoking, a composite measure of healthy lifestyle was created, and it found that in the United States only 3% of the adults had a healthy lifestyle. 14 Recently, based on the Healthy People 2020 agenda, a new composite measure for the US population was created, including sleep. 15 In that study, 7.7% of the adults reported a healthy lifestyle. However, in spite of these studies, there is not much information about the prevalence of healthy lifestyles in European countries. Thus, it is important to have more knowledge in this area which could help to improve public health guidelines. Therefore, the purpose of this study was to analyze the healthy lifestyle for European adults, using data from the European Social Survey 2014. The association between lifestyle and sociodemographic characteristics of the population was also reported.
Methods
Data and Participants
Data were retrieved from the European Social Survey 2014 database. The European Social Survey is a study that has been conducted every 2 years since 2002 to measure the attitudes, beliefs, and behaviors of European adults. This survey uses representative samples among countries, from residents aged 15 years and over, excluding the homeless and institutionalized people. Participants were 40 185 people from 20 European countries (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Ireland, Lithuania, Netherlands, Norway, Poland, Portugal, Slovenia, Spain, Sweden, Switzerland, and United Kingdom) and Israel. Participants were sampled by postal code, address files, social security registry data, population registers, and/or telephone books. The information was collected in each country, using a questionnaire filled in through an hour-long, face-to-face interview. The questionnaire was translated, by language experts, into the language spoken in each of the participating countries. More details about the European Social Survey are available elsewhere. 16 The study protocol subscribes to the Declaration on Professional Ethics of the International Statistical Institute.
For the present study, participants under 18 years of age were excluded (n = 1215) because the focus was on the adult population. Respondents without information in more than 2 sociodemographic variables, and without information regarding physical activity, eating habits, sleep quality, alcohol drinking, and smoking were also excluded (n = 1201). Since Israel is not a European country, its participants were excluded (n = 2136). These restrictions resulted in a final sample of 34 993 participants (Austria = 1714, Belgium = 1632, Czech Republic = 1981, Denmark = 1418, Estonia = 1890, Finland = 1960, France = 1750, Germany = 2831, Hungary = 1596, Ireland = 2251, Lithuania = 1877, Netherlands = 1800, Norway = 1376, Poland = 1471, Portugal = 1160, Slovenia = 1141, Spain = 1843, Sweden = 1697, Switzerland = 1454, and United Kingdom = 2152).
Measures
Healthy lifestyle behaviors
The 5 behaviors used for the creation of the healthy lifestyle measure included physical activity, fruit and vegetable consumption, sleep quality, alcohol drinking, and smoking. These behaviors are all recognized as important behaviors associated with health. 4 -6,8
Physical activity was assessed with a single item asking, “On how many of the last 7 days did you walk quickly, do sports, or other physical activity for 30 minutes or longer?” Although physical activity was assessed by a single question, there is evidence that this is an acceptable way to assess physical activity 17 ; this approach was used previously with the European Social Survey data. 18,19 Participants were classified as having attained the recommended level of physical activity (≥30 minutes of at least moderate physical activity on ≥5 occasions per week) or not having attained the physical activity recommended levels (<30 minutes of at least moderate physical activity on ≥5 occasions per week), according to the European Physical Activity guidelines. 20
Fruit and vegetable consumption was addressed through the questions, “How often do you eat fruit, excluding drinking juice?” and “How often you eat vegetables or salad, excluding potatoes?” Responses to these 2 questions were combined to assess the total fruit and vegetable daily consumption. Several dietary guidelines advise the consumption of ≥5 portions of fruit and vegetables per day. 21 However, in Europe, the definition of fruits and vegetables, and its recommendations, varies between countries. 22 Therefore, to have a cutoff point that was suitable for all countries, the consumption of ≥4 portions of fruits or vegetables (or fruit and vegetables combined) a day was considered appropriate.
The European Social Survey data does not have information of sleep duration. It does provide information regarding sleep quality. As a proxy of the sleep behavior, the information provided in the question was used: “For how much of the time, during the past week, was your sleep was restless?” Response options were: “none or almost none of the time,” “some of the time,” “most of the time,” and “all or almost all of the time.” Healthy sleep behavior was considered if respondents answered that sleep was restless none or almost none of the time. The other response options were considered unsatisfactory sleep quality.
The amount of alcohol consumed was measured in grams, derived by adding the reporting of all beverages consumed the last time the respondent drank alcohol on a weekday and the last time the respondent drank alcohol on a weekend day, respectively. Alcohol consumption guidelines vary between countries in Europe. 23 For this study, the guidelines from the Department of Health 24 were adopted. This more restrictive recommendation was used because there is evidence that alcohol consumption, even at moderate levels, is associated with adverse brain outcomes. 25 Light drinking was defined as between 1 and <7 units/week and moderate drinking was 7 to <14 units/week for women and 7 to <21 units/week for men. Not drinking excessively was defined as ≤14 units/week (112 g) for women and ≤21 units/week (168 g) for men.
Participants were asked about their smoking behavior. Response options ranged from, “I have never smoked” to “I smoke every day”. Because there is no threshold of safety for smoking cigarettes, responses were recoded into current smoker (regularly or sometimes), and not smoking.
Healthy lifestyle composite score
The composite score of healthy lifestyle was created using the combination of the 5 healthy behaviors described above. Participants scored 1 point for achieving each of the following lifestyle categories: (1) physical activity ≥5 times/week, (2) consumption of ≥4 portions of fruits and vegetables a day, (3) not having a restless sleep, (4) not drinking excessively, and (5) not smoking. Thus, the healthy lifestyle score ranged from 0 to 5, with only a score of 5 representing a healthy lifestyle. To ensure that the composite score of healthy lifestyle was related to a better health, it was analyzed its relationship with self-rated health, life satisfaction, and the number of chronic diseases. It was clear that people with a healthy lifestyle had better health perception, reported better life satisfaction, and also less chronic diseases.
Other variables
Participants reported sex, age, and years of full-time education (recorded as low, middle, and high, according to the International Standard Classification of Education). 26 Respondents were asked to describe whether they live with or without a husband/wife/partner and the legal situation. Response options were dichotomized into live with, or without, a partner. Household income was determined based on decile. Using this data, 1st to 3rd decile, 4th to 7th decile, and 8th to 10th were organized to create 3 groups. Participants were asked to report their occupation. To determine the living place, those who indicated that they lived in a big city, the suburbs, or the outskirts of a big city were grouped into a new category named “urban areas”; those who responded that they lived in the countryside, in a village, or in a house in the countryside were grouped into a category called “rural areas.”
Data Analysis
Descriptive statistics were calculated (means, standard deviation, and percentages) for the entire sample and were stratified by sex. Point estimates and 95% confidence intervals (CIs) were reported for the prevalence for each of the healthy lifestyle behaviors, for the number of behaviors reported, and for the mean number of behaviors reported. Chi-square and Student t test were used to compare men and women according to sociodemographic characteristics and healthy lifestyle behavior. Binary logistic regression was done to determine associations of healthy lifestyle and sociodemographic characteristics. Statistical analysis was performed using SPSS version 24. The significance level was set at P < .05.
Results
Table 1 presents the characteristics of the study sample. Prevalence rates for each of the healthy lifestyle behaviors are shown at the top of Table 2. The range of rates was from 21% for eating fruits and vegetables ≥4 times/day, and 89.1% for not drinking excessively. Comparing sexes, men were more likely to engage in physical activity ≥5 days/week than women (34.5% vs 32%, P < .001) and were also more likely not to have restless sleep than women (87% vs 79.8%, P < .001). On the other hand, women were more likely to eat ≥4 portions/day of fruits and vegetables (25.7% vs 15.7%, P < .001), not drink excessively (91.2% vs 86.8%, P < .001), and not smoke (79.6% vs 71.3%, P < .001) than men. Only 5.8% (4.7% men, 6.7% women) of the adults reported achieving all 5 healthy behaviors, while 42.3% (42.6% men, 42.1% women) reported at least 3 behaviors.

The relationship between having a healthy lifestyle and sociodemographic factors is presented in Table 3. For the entire sample, middle age (odds ratio [OR] = 1.20, 1.04-1.38, P < .05), older people (OR = 1.34, 95% CI: 1.07-1.67, P < .001), those having higher household income (OR = 1.33, 95% CI: 1.15-1.54), being a student (OR = 1.38, 95% CI: 1.08-1.77), and retired (OR = 1.31, 95% CI: 1.12-1.52, P < .001) presented a higher likelihood of having a healthy lifestyle. On the contrary, those who lived without a partner (OR = 0.82, 95% CI: 0.73-0.93, P < .001), unemployed (OR = 0.73, 95% CI: 0.55-0.97, P < .05), and lived in rural areas (OR = 0.86, 95% CI: 0.77-0.96, P < .01) were less likely to have a healthy lifestyle. For men, education level and living places were sociodemographic characteristics related to a healthy lifestyle but not in women.

Discussion
This study aimed to measure healthy lifestyle for European adults. Despite the recognized importance of engaging in physical activity regularly, eating fruits and vegetables daily, sleeping well to rest, not drinking excessively, and not smoking, very few European adults have a healthy lifestyle as defined here. Physical activity and fruit and vegetable consumption seemed to be the behaviors that offer the best possibilities to improve the composite measure and have more people healthier. Differences among countries were observed. The relationship between the composite measure of healthy lifestyle and sociodemographic factors demonstrated that there are some social inequities. For example, people with high household income were more likely to have a healthy lifestyle, when compared to those from lower household income.
Results from this study were similar with an earlier study in the United States, which also found a low rate of people with a healthy lifestyle, although the measure was slightly different. 15 The similar results between European and Unites States population indicate that people from these 2 regions have comparable lifestyles. The lower prevalence of healthy lifestyle in Europe and the United States might be a function of the individual lifestyle characteristics and how the behaviors aggregate or cluster together. Among the healthy lifestyle behaviors, physical activity and fruit and vegetable consumption had the lowest prevalence. This is consistent with the high prevalence of physical inactivity 27,28 and low consumption of fruits and vegetables among European adults. 29 As a response, the World Health Organization and the European Union have implemented strategies that aim to enhance the levels of physical activity and fruit and vegetable consumption in Europe, in order to reduce the prevalence and incidence of chronic disease and premature death. 3,29
A healthy lifestyle or a combination of at least 4 behaviors (eg, engaging in physical activity regularly, having a healthy diet, moderate alcohol intake, and never smoking) is related to reduction in morbidity, 11,12 mortality, 9 and having a longer life with good health. 10 Thus, considering that lifestyle behaviors, either individually or combined into a composite score, are associated with health outcomes, 10 -12 European adults seem to be at risk of having chronic diseases, because <6% are reported to have reached all 5 healthy behaviors.
Several studies still analyze individual health behaviours. 9 However, looking at the health behaviors individually, one could say that, for example, the majority of the population does not drink excessively or does not smoke. When assessing healthy lifestyle based on a single behavior, it seems that a high proportion of the adult population has a healthy lifestyle. On the other hand, as previously acknowledged, 15 a measure of healthy lifestyle offers a new public health perspective, usually using recognized health behaviours 30 and provides new insight into the population’s health status. When using a composite measure of healthy lifestyle, it is highlighted that more than 90% of the European adult population should be targeted for improving their health. Therefore, a more holistic approach seems to be more accurate to determine the lifestyle and to point out new directions for improving. For instance, the lower prevalence of engaging in regular physical activity and fruit and vegetable consumption underlines the need to work more in these areas. It means that investments in promoting these behaviors might increase the number of people with a healthy lifestyle. These results demonstrate the usefulness of the healthy lifestyle composite measurement, mainly because research has made clear that having 4 or more healthy behaviors decreased the risk of mortality. 9 For that reason, a refined version of a healthy lifestyle composite score, using standardized variables that can be used in different countries and regions, would be an advantage for international comparative investigations. This would be important for policy makers, because they would be able to compare results among countries and regions, encouraging international collaboration in initiatives to face mutual challenges associated with unhealthy lifestyles.
People, men and women, with higher household income are more likely to have a healthy lifestyle compared to those with lower household income. Likewise, more educated men, and people who live in urban areas, have a better likelihood of having a healthy lifestyle. Such results show that there are social inequities toward having a healthy lifestyle. The World Health Organization has been addressing several messages to reduce social inequities in health promotion, mainly for the prevention and control of chronic diseases. 3,31 It is recommended that policy makers need to engage in planning actions to promote healthy lifestyles and reduce social inequities. 32 For this purpose, interventions have to tackle the macro-environmental factors, the social and physical environment, the adverse health behaviors, and access to health-care services. 3,31
There are several limitations in this study. All data were self-reported, and reliability and validity have not been studied for all measured healthy lifestyle behaviors. So far, there is no consensus regarding how to define a healthy lifestyle. In Europe, there are different guidelines for fruit and vegetable consumption, as well as guideline variations between countries, so it is difficult to define a cutoff point. 22 There is also no consensus concerning the specific nutritional components that constitute a healthy diet. Similarly, the amount of alcohol defined as moderate consumption is not the same in all European countries. 23 For these reasons, guidelines from the Department of Health were adopted, which are more conservative. 24 A question to assess sleep duration was not included; thus, a proxy variable of sleep was used instead. Although this variable provided information on quality of sleep, there was no guarantee that participants had slept ≥7 hour per night, as recommended. 33 Furthermore, the cross-sectional design of the study precludes making a causal inference for the relationship between healthy lifestyle and sociodemographic factors. Results need to be interpreted with the above issues in mind.
So What?
What is already known on this topic?
Healthy lifestyle is combination of behaviors, and a healthy lifestyle is associated with better health outcomes and lower mortality rates.
What does this article add?
Although engaging in physical activity regularly, eating fruits and vegetables daily, sleeping well, not drinking excessively, and not smoking are well recognized as being related to health outcomes, less than 6% of European adults reported achieving all 5 healthy behaviors. Physical activity and fruit and vegetable consumption seemed to be the behaviors that offer the best possibilities to improve the healthy lifestyle of European people.
What are the implication for health promotion practice or research
A refined healthy lifestyle composite score, using the same variables in different countries and regions, would be an advantage for comparative investigations. An international healthy lifestyle composite score would help policymakers to compare results among countries and regions, encouraging international collaboration in initiatives to face mutual challenges associated with unhealthy lifestyles.
Conclusions
This study presents a new composite lifestyle measure for European people, comprised of engaging in physical activity regularly, eating fruits and vegetables daily, sleeping well, not drinking excessively, and not smoking. Although these 5 behaviors are well recognized as being related to health outcomes, <6% of European adults reported all 5 healthy behaviors. From this study’s results, it is clear that enhancing the levels of physical activity and fruit and vegetable consumption offers the greatest potential for improving the prevalence of European adults with a healthy lifestyle. This should be both a message for governments and a consideration in the establishment of preventive public policies in the areas of health and health education.
