This chapter focuses on the interaction between lifestyles, health, and life satisfaction of Portuguese seniors. The aim of the analysis is to find the main determinants of health and life satisfaction and to verify the importance of lifestyle variables as determinants of health and life satisfaction. We used data collected by the National Health Survey of 2014 and estimated two ordered probits. The main results show that not all lifestyle variables are meaningful in explaining self-assessed health and life satisfaction. The determinants of the health status include education and income; however, it can be assumed that overall good health, family, or close people and income contribute to life satisfaction. A general profile of the Portuguese seniors is provided; however, the results obtained here are changing as a new scenario is emerging, generation X enters old age.

1. Introduction

Portugal is one of the oldest countries in Europe and the country where the share of older people is growing faster [1]. The life expectancy at birth, in 2018, was 78.3 and 84.5 years for males and females, respectively, and it slightly improved between 2014 and 2018 (Table 1); life expectancy at 65 years old was 18.2 and 22.0 years for males and females, respectively, in 2018. Nevertheless, Portuguese elderly enjoy short healthy life years when they reach 65, while males may enjoy 7.8 healthy years, women enjoy 6.9 according to data for 2018 (Table 1). Summing up, older Portuguese people live long lives but without quality of life.

Portuguese are in general less satisfied with life (OECD, Eurobarometer since 1973, Gesis [3, 4, 5]; European Social Survey [6, 7, 8]). When people are asked “on the whole how are you satisfied with your overall life,” Portuguese tend to report lower level of satisfaction than the other Europeans (Figure 1).

The same trend about life satisfaction is found in other older people. Based on SHARE survey (SHARE [9]), wave 6, comparing life satisfaction across several European countries, the share of Portuguese seniors reporting life dissatisfaction (levels 0–3 in a scale of 0–10, where 0 means completely dissatisfied and 10 completely satisfied) is nearly 7.5% of the respondents, while the average for the remaining countries in the sample is about 2.8%.

Health and life satisfaction have long been studied, as well as their interconnectedness [10, 11, 12, 13]. The determinants of health and life satisfaction, in general, coincide [14, 15, 16, 17], and they include demographics, socioeconomic status, overall well-being (physical and mental health), and social interactions.

People’s lifestyle choices also influence health [18, 19] and life [20], as is frequently pointed out by the WHO [21, 22, 23]. Healthy lifestyles mean eating a healthy diet with vegetables and fruit, no smoking, not drinking excessively, and being involved in some regular exercising. These are means to prevent the onset of non-communicable chronic diseases such as cardiovascular diseases, diabetes, cancer, and dementia.

Older Portuguese people and issues in relation to their health, life satisfaction, and lifestyles have so far received limited research interest; however, there are some studies that approached these issues. Concerning health, Portuguese people aged 65 and over tend to report satisfaction with their health [24], and the determinants are aligned with international studies, i.e., as people get older, especially women, who are less educated and those of low socioeconomic status, tend to report lower health status [25].

Studies on life satisfaction, happiness, or well-being in Portugal indicate that despite socioeconomic status being a relevant determinant, other factors such as social networks and personal relationships are also related to health and provide more important explanatory factors [25, 26]. At the beginning of the twenty-first century, Delhey [27] revealed that the three most relevant factors for quality of life in Portugal were primarily health, followed by family and then income.

Focusing on diet, Santos et al. [28] found that overall seniors tend to have a low-quality diet, especially single males, but those living in rural areas were more likely to have a better diet.

We do not know much about alcohol intake and smoking of older people in Portugal. Bosque-Prous [29] using SHARE data showed that Portugal has a high prevalence of hazardous drinking.

This is different when it comes to the use of tobacco. Older people do not display a profile of heavy smokers, and as they get older, they tend to smoke less [30], but smokers tend to consume more alcoholic beverages and have a poorer diet [31]. Physically active seniors tend to delay aging decay [32], and, based on SHARE data, the prevalence of inactive older people is very high in Portugal, and that may be due to depression, low social support, and low life satisfaction [33].

This chapter has two aims. First is to describe and analyze the lifestyles, health, and life satisfaction of Portuguese seniors. Second is to identify the main explanatory factors of self-assessed health and life satisfaction of Portuguese seniors.

The conceptual map framing our analysis is presented in Figure 2. Lifestyle choices are based on health and life satisfaction, so we consider determinants such as demographics, socioeconomic status, and health related issues. These determinants influence the way older Portuguese people perceive their health and create their awareness about life satisfaction. Once the most important determinants have been identified, then policy measures may be designed to improve the general health, overall well-being, and life satisfaction by influencing those determinants.

This chapter proceeds with the description of the methods used to achieve the aims of the analysis. Then the results are presented, and, at the end, the discussion outlines some systemic as well as personal changes to influence unhealthy lifestyle choices.

2. Method

2.1 Data and sample

Data used for the analysis performed in this chapter is collected by the National Health Survey (NHS) of 2014 [34]. This survey is a community-based cross-sectional study. Data collected is obtained according to a multistage stratified and cluster sampling. The obtained sample represents the Portuguese population. The survey was implemented in the whole country between September and December 2014, and it included 18,204 people aged 15 year or over, who are not institutionalized. The questions in the survey covered four thematic areas: health status, healthcare, health determinants, and income and health expenses. The NHS 2014 is a survey harmonized and regulated in EU level [Commission Regulation (EU) No 141/2013].

Our sample includes all respondents older than 65 years from the whole of the country, that is, 5701 Portuguese seniors. Analyses were conducted with Stata version 15 (StataCorp LP, College Station, Texas, USA).

2.2 Variables

The dependent variables of this study are the self-assessed health (henceforth SAH) and the life satisfaction (henceforth LS). The independent variables comprise a set of independent variables grouped in demographic, socioeconomic, health and physical conditions, and lifestyle variables. These variables are described in the following.

2.2.1 Dependent variables Life satisfaction

Life satisfaction is captured by the survey question “are you satisfied with your life?”. The answers are graded in a scale 1–7 where 1 means “I completely disagree” being satisfied and 7 means “I completely agree” being satisfied. Self-assessed health

Self-assessed health is obtained from the question “how do you evaluate your health status.” The answer varies from 1 to 5, where 1 means “very bad” and 5 means “very good.”

2.2.2 Independent variables

The independent variables are grouped in demographic, socioeconomic, health and physical conditions, and lifestyle variables which are described in Table 2.

Concerning life satisfaction, most Portuguese seniors reported being satisfied with life. Around 67% of respondents evaluated their life satisfaction at the highest levels (levels 5–7) of satisfaction (Table 4). So, despite the generally negative reporting of their health status, seniors are satisfied with life.

Descriptive statistics for independent variables.

Most of the seniors surveyed are women, and about half of them are aged between 65 and 75 years old. More than half of the surveyed seniors have a very low level of education; the majority are married, and, in general, they receive very low levels of income.

Concerning the health and physical conditions, the large share of older Portuguese suffer from chronic diseases and/or from depression; they face some minor form of physical limitation to perform daily tasks, and they are overweight.

Finally, a great number of the older population do not do any exercise, but they do not smoke either; a great number report having eaten unhealthy food in the previous day, but a very large number of older people eat fruit and salad daily or very often; almost 30% of the respondents stated to drink alcohol very frequently such as every day or 5–6 times a week.

The correlation between binary variables is given by the tetrachoric correlation. This was computed for lifestyle variables (Table 6). None of the correlations is very high, but there is some positive correlation between people who frequently drink alcohol and those who smoke; there is also a negative correlation between people who smoke and those who eat frequently fruit and salad.

3.2 Estimation results

The estimation results of the ordered probits for self-assessed health and life satisfaction are presented in Table 7. The ordered probit for self-assessed health shows that demographic variables are not significant but, as expected, higher education and higher income are correlated with higher health status. The existence of chronic diseases, suffering physical limitations and feeling depressed, does not contribute to good health. Interestingly, we found that smoking and drinking are associated with the people’s higher odds of reporting good health; but we also found that good health is reported when people exercise, as expected.

Table 7.


Concerning the ordered probit for life satisfaction, results are slightly different. Older people, and females particularly, tend to report higher levels of life satisfaction. Higher income is correlated with higher life satisfaction; no matter whether people are married or single, they tend to report identical satisfaction; however, having more than one person in the household increases the likelihood of reporting life satisfaction. Concerning the health variables, the results coincide with those found for self-assessed health. Any condition that risks the healthy feeling of people decreases life satisfaction except the BMI. Overweight is not correlated with lower but with higher life satisfaction. Finally, concerning lifestyle variables, we found that eating unhealthy food, drinking alcohol, and exercising are positively correlated with life satisfaction.

Table 8 presents marginal effects for the significant lifestyle variables. It can be observed that for low levels of health, the change from “no frequent alcohol drinking” to “frequent drinking” and from “no frequent smoking” to “frequent smoking” decreases the perceived health status. Identically, for levels of life satisfaction below level 6, the change from “no frequent alcohol drinking” to “frequent alcohol drinking” and from “no unhealthy food” to “eating unhealthy food” decreases life satisfaction. Being physically active increases the “good health status” and also boosts the life satisfaction to higher levels (meaning levels 6 and 7). The gray shadowed values are statistically significant for a p-value smaller than 0.05.

4. Discussion

Portugal is already a country of older people in Europe, and, as overall longevity increases, the number of people over the age of 65 will increase. Understanding the determinants of self-assessed health and life satisfaction and also understanding the role of lifestyle choices as determinants provide the basis for specific policy measures aimed at improving the overall well-being of senior citizens. The aim of this chapter was to estimate the set of main determinants and check the relevance of lifestyle variables as determinants of self-assessed health and life satisfaction of Portuguese people who are older than 65 years. We used data collected by the National Health Survey of 2014 and estimated two ordered probits.

The main results show that not all lifestyle variables are significantly explaining self-assessed health and life satisfaction. Surprisingly, we found that people who smoke and drink alcohol frequently reported a good health status; a good health status was also reported by those who frequently exercised. We also found that people reporting to eat unhealthy food and drink alcohol frequently tended to report higher life satisfaction as those reporting frequent physical exercise.

These results were unexpected. It may be argued that the participants only included people older than 65 years. At this age, people may feel that there is no need to change their behavior concerning smoking and drinking. They may think that the life time left should be comfortable and not restrictive. In fact, the share of people reporting smoking and drinking is relatively small, and their present health condition seems to let them satisfy their wishes or habits in relation to smoking and drinking.

The marginal effects confirm this to some extent. When people report low levels of health, when moving from “no smoking” to “smoking” or from “no drinking alcohol” to “drinking alcohol,” a decreasing health status is reported. But for good levels of health, this tendency does not happen. It looks as if the good health status works as a protective status allowing people to make less healthy choices.

The determinants of the health status of older Portuguese follow previous studies, as was expected; good education and higher income contribute to a better health outcome. Interestingly, the opposite happens with married people, they are more likely to report bad or very bad health. It may be married people assess their own health in comparison with their partner or assess it as a joint indicator of the couple. This result must be carefully interpreted because married people also tend to report more often satisfied life satisfaction.

Determinants of life satisfaction follow the findings by Delhey [27]. Good health, family or close people, and decent income contribute to life satisfaction. Being a female and getting older also contributes to life satisfaction. Bad health conditions, affecting people physically or emotionally, decrease the health status and life satisfaction of people.

People older than 65 years belong to the generation of baby boomers, and the oldest belong to the silent generation. The silent generation was born between 1928 and 1945, and the baby boomers were born between 1946 and 1964. Portugal was under an authoritarian corporatist government for 41 years, from 1933 to 1974. This means that people from these generations were born, raised, and worked under this political regime. Their values and attitudes were strongly shaped by their life experience. They have accomplished very low levels of education, and their retirement pensions are very low. This seems to have influenced the way people assess their health and life satisfaction, as well as their expectations and ambitions for life and health.

It is clear that many older Portuguese would improve their health and life satisfaction, had they received better education, and were entitled to larger retirement pensions. The very low level of income, often at level or below level of risk of poverty, requires particular attention from the authorities to prevent old age poverty and catastrophic health expenditures in future.

In general, older people are not smokers or heavy smokers, nor are they heavy drinkers. These characteristics, which are based on their socioeconomic condition, contribute to their health status and life satisfaction. However, some of their lifestyle choices will have negative health consequences. Those who tend to smoke are also more likely to drink alcohol, and this combination may potentiate future diseases and faster degradation of the health condition.

The large share of older people living in rural areas has the opportunity to grow their own vegetables and harvest fruits. For this reason, they are very likely to have a healthy diet and consume frequently vegetables, salads, and fruits. These people are very unlikely to engage in formal physical activity, but they are physically active in their life when growing vegetables and taking care of farm animals, all of which contributes to their well-being.

Future research on these topics needs to focus on the analysis of the unhealthy choices and their impact on health and life satisfaction. The results found here are changing in the near future because a new scenario is emerging. It may be worth analyzing the changes occurring as the baby boomers’ generation dies and generation X enters old age.
