P09-07 Physical activity and sedentary behaviour patterns among French adults during the COVID-19 health crisis

Abstract Background The COVID-19 health crisis and the various restrictions (lockdowns) implemented may have impacted individuals' behaviours (e.g. physical activity [PA] and sedentary behaviour [SB]) and psychological health (e.g., self-esteem or adjustment strategies to cope with stressful events). The objective of this study was to identify PA and SB patterns and to investigate their associations with socioeconomic and psychological characteristics among French adults during the COVID-19 health crisis. Methods Cross-sectional data of French adults were collected during the COVID19 health crisis (between March 2020 and February 2021). PA and SB were measured using the International Physical Activity Questionnaire. The Rosenberg Self-Esteem Scale and the Brief Cope questionnaire were used to measure self-esteem and coping strategies, respectively. PA and SB cross-sectional patterns were identified using latent class analysis. Multivariable logistic regression models were used to investigate associations between identified patterns and adults' socioeconomic factors, self-esteem, and coping strategies. Results Among the 241 included adults (mean age ± standard deviation: 29.6 ± 13.1 years), three cross-sectional PA and SB patterns were identified: sedentary walker (n = 141; 58.5%); varied PA practitioner (n = 68; 28.2%); walker with intense PA (n = 32; 13.3%); Compared to the sedentary walker pattern, the walker with intense PA one was overrepresented by socially less advantaged adults, using more planning and less religion as coping strategies to stressful events, and those in the varied PA practitioner pattern used more denial as coping strategy. Conclusions More than half of adults were in the least healthy pattern (sedentary walker). These results suggest using PA and SB as levers to cope with stressful life events.


Background
Sedentary time (sitting) has been associated with adverse cardio-metabolic consequences. The general recommendation is to interrupt long periods of sitting. In order to successfully develop interventions and policies to decrease sedentary behaviour, high-risk groups as well as the context of sitting should be identified. The aim of this study was to investigate sedentary behaviour among (subgroups of) the Dutch population and to identify in which domains most sedentary time was spent. Methods Data from the 2017 Dutch national Health Interview Survey was used, which includes a nationally representative sample of 8,441 Dutch citizens aged 4 years and older. Sedentary time on an average day was assessed using an adjusted version of the Marshall questionnaire. Sitting domains were defined as: 1) traveling, 2) at work, 3) at school or studying 4) watching television, 5) using a computer/smartphone at home, and 6) otherwise. Total sedentary time was analysed stratified by age, sex and level of education with ANOVA and Bonferroni correction.

Results
On average the Dutch population accumulates 9,0 hours/day of sedentary time. Overall, participants accumulated most sedentary time while watching television (2.2 hours/day) followed by sitting at work and other activities (both 1.7 hour/day). Significant differences (p > 0.001) were found by sex, age group and level of education. Men reported slightly more sedentary hours than women (9.2 vs. 8.8 hours/day). With respect to age groups, adolescents (12-17 years old) reported the highest, whereas children (4-11 years old) reported the lowest sedentary hours (10.1 vs. 7.3 hours/day). Finally, sedentary hours were high for higher educated people (9.7 vs. 8.2 hours/day in lower educated people). Adolescents accumulated most sedentary time at school or during studying (4.0 hours/day), higher educated people accumulated most sedentary time at work (3.4 hours/day).

Conclusions
Our study showed that in general Dutch people spend a lot of time sedentarily, especially adolescents and higher educated people. Most sedentary times was spent while watching television, at school or during studying, and at work. Therefore interventions aiming to decrease sedentary beha-  [SB]) and psychological health (e.g., self-esteem or adjustment strategies to cope with stressful events).

Results
Among the 241 included adults (mean age AE standard deviation: 29.6 AE 13.1 years), three cross-sectional PA and SB patterns were identified: sedentary walker (n = 141; 58.5%); varied PA practitioner (n = 68; 28.2%); walker with intense PA (n = 32; 13.3%); Compared to the sedentary walker pattern, the walker with intense PA one was overrepresented by socially less advantaged adults, using more planning and less religion as coping strategies to stressful events, and those in the varied PA practitioner pattern used more denial as coping strategy.

Conclusions
More than half of adults were in the least healthy pattern (sedentary walker). These results suggest using PA and SB as levers to cope with stressful life events.
