Summary: According to researchers, older adults who engage in activities perceived to be worthwhile, such as supporting grandchildren or completing a project, have better sleep, walking speeds and experience less chronic pain.
Engaging in activities perceived to be worthwhile such as supporting children and grandchildren or completing a satisfying project are linked to walking faster, sleeping better and experiencing less chronic pain in later life, according to a new UCL study.
The paper, published today in Proceedings of the National Academy of Sciences (PNAS) journal found that having a sense of purpose and feeling engaged in ‘worthwhile’ activities may promote health and happiness in later life.
Participants were asked to what extent they felt the things they did in their life were worthwhile on a scale of one to ten. Compared with people who did not rate the things they do in life as worthwhile, those with high ratings walked 18% faster, had an average 13% higher concentration of vitamin D in their bloods, and were more than twice as likely to report having good sleep.
Researchers analysed data and biological markers from over 7,000 adults aged over 50 between 2012 and 2016 who had taken part in the English Longitudinal Study of Ageing (ELSA).
“As more and more men and women live longer, we need to understand better what factors lead to healthier and happier older age,” said lead co-author, Professor Andrew Steptoe (UCL Behavioural Science and Health).
“This is a two-way process. Not only do good social relationships and better health contribute to our sense that we are living meaningful lives, but this sense of meaning sustains social and cultural activity, health and wellbeing into the future.”
After taking into account factors such as age, sex, education, and occupational prestige (a marker of mid-life socioeconomic status), the researchers found that higher ratings of doing worthwhile activities were also positively linked to strong personal relationships, affluence (income and wealth) , healthier lifestyles, better mental and physical health, and more time spent exercising and socialising.
Higher ratings were also associated with favorable biomarkers, such as faster gait speed, stronger hand grip, higher-density lipoprotein cholesterol, higher vitamin D concentrations, less obesity, and lower plasma C-reactive protein and lower white blood cell counts.
In addition, higher ratings of doing worthwhile activities in 2012 predicted better outcomes four years later. Compared with people who reported higher worthwhile ratings, people with low ratings were twice as likely to develop depressive symptoms over this period, and 30% more likely to develop chronic pain. Worthwhile ratings were inversely associated not only with loneliness and living alone, but also with time spent alone on the previous day.
Professor Steptoe explained: “The study suggests that a spectrum of behavioral, economic, health, and social variables are related to whether ageing individuals believe they are living meaningful lives, but also that these beliefs determine future health and wellbeing.
“We need more and better data about purpose in life from the population at large in order to tease out better ways to promoting a good life in middle and older age.”
Dr Daisy Fancourt, lead co-author added: “We do not know what activities the participants in this study thought were worthwhile. For some it might be supporting their families, for others a particular accomplishment in their work or hobby, enjoying nature or perhaps following a favourite sports team. What is important is that the individual finds these activities worthwhile and feels they give a sense of meaning to life.”

Leading a meaningful life at older ages and its relationship with social engagement, prosperity, health, biology, and time use
The sense that one is living a worthwhile and meaningful life is fundamental to human flourishing and subjective well-being. Here, we investigate the wider implications of feeling that the things one does in life are worthwhile with a sample of 7,304 men and women aged 50 and older (mean 67.2 y). We show that independently of age, sex, educational attainment, and socioeconomic status, higher worthwhile ratings are associated with stronger personal relationships (marriage/partnership, contact with friends), broader social engagement (involvement in civic society, cultural activity, volunteering), less loneliness, greater prosperity (wealth, income), better mental and physical health (self-rated health, depressive symptoms, chronic disease), less chronic pain, less disability, greater upper body strength, faster walking, less obesity and central adiposity, more favorable biomarker profiles (C-reactive protein, plasma fibrinogen, white blood cell count, vitamin D, high-density lipoprotein cholesterol), healthier lifestyles (physical activity, fruit and vegetable consumption, sleep quality, not smoking), more time spent in social activities and exercising, and less time spent alone or watching television. Longitudinally over a 4-y period, worthwhile ratings predict positive changes in social, economic, health, and behavioral outcomes independently of baseline levels. Sensitivity analyses indicate that these associations are not driven by factors such as prosperity or depressive symptoms, or by outcome levels before the measurement of worthwhile ratings. The feeling that life is filled with worthwhile activities may promote healthy aging and help sustain meaningful social relationships and optimal use of time at older ages.
