Physical activity and sedentarism among seniors in France, and their impact on health

Abstract

Background In the context of the ageing of the French population, physical activity becomes a principal means for maintaining good health. International organisations are thus giving increasing importance to physical activity in programmes of disease-prevention. In parallel with these concerns, studies have shown the impact of sedentary activities (in particularly as a result of the seated position and screen time) on health. Objective To show the links between physical activity, sedentarism and health indicators and to identify the socio-demographic variables by which they are influenced (particularly gender). Study design This is a transversal epidemiological study conducted among the French population between 2014 and 2016 by Santé publique France, the national public health agency. Methods The RPAQ (Recent Physical Activity Questionnaire) was used to measure the physical activity and sedentary lifestyle of individuals. The analyses focus on the behaviours among the population of older adults (55–74 years old, n = 1155). Results A third of French older adults does not meet the WHO recommended physical activity levels, particularly so among women. The results of this survey point to significant links between health indicators (especially overweight and obesity) and the physical activity level and sedentarity of older adults. From the age of 60, energy expenditure linked to physical activity increases before decreasing from the age of 65. Older adults spend almost 6 hours per day in sedentary activities. The combinations between physical activity and sedentarism highlight four profiles of older adults. The most active profile is the one with the best health indicators. Conclusion The links between health, sedentarity and physical activity are unequivocal: people who achieve the WHO recommendations for physical activity and spend less than 7 hours each day in sedentary activities are those who also have the best health indicators. These results vary with sociographic characteristics and reveal significant links with health indicators.

Mediterranean Diet Adherence in Community-Dwelling Older Adults in Spain: Social Determinants Related to the Family

“…However, it is surprising that in our sample, which had a physically active lifestyle, a higher energy expenditure due to physical activity did not imply a better adherence to MD. Several hypotheses could explain this finding; first, the dual profile that the elderly in our study may have, as regardless of compliance with the recommended values for physical activity, they may present sedentary behaviors such as spending more than 5 h a day in front of a screen, a popular activity among older adults [ 22 ]. Second, according to “the paradox of physical activity”, it is possible that rather than the amount of energy expended, the nature of the activities carried out has the most influence on a healthy lifestyle [ 68 ].…”

“…However, industrialization, urbanization, economic development, and globalization of the food market are changing eating habits and lifestyles at all ages [ 18 , 19 , 20 , 21 ]. This is all leading to the adoption of sedentary lifestyles (which consequently reduce energy expenditure) and the choice of foods of poorer nutritional quality (such as snacks and refined, processed, and high-fat foods) [ 22 , 23 ].…”

Older adults’ immobility: disentangling choice and constraint

“…Since then, social isolation has become a major public health issue (Murthy 2023), with reports from the World Health Organization targeting older adults (Mikton et al 2021). In parallel, sedentary lifestyles have long been pointed out as "a risk factor in non-communicable diseases" (Pierre et al 2022).…”

Use of Wearables in Frail Institutionalized Older Adults While Ambulating in Different Environments

“…In older individuals living in the community, the presence of frailty is associated with a decrease in physical activity, lower energy expenditure, and increased sedentary behavior [6], making physical activity a protective factor against this frailty syndrome [7,8]. Older adults spend around 6 h per day in sedentary activities [9]. As a result, after the age Appl.…”
