Socio-economic inequalities in physical activity among Japanese adults during the COVID-19 pandemic.
This study aimed to explore the socio-economic inequalities in physical activity (PA) based on domains of daily life, such as work, transport, recreation and sedentary life, among Japanese adults during the COVID-19 pandemic.
This was a cross-sectional study.
This study used data from the 2020 National Sport and Lifestyle Survey, conducted by the Sasakawa Sports Foundation. Data of 2,296 (1,103 women) participants were analysed. PAs were assessed using the Global Physical Activity Questionnaire. Educational level and household income were used as indicators of socio-economic status. We calculated the slope index of inequality (SII) and relative index of inequality (RII).
We detected absolute and relative inequalities for household income in all PA domains, except for work-related PA. The higher the participants' income, the longer they engaged in transport- and recreation-related PA and sedentary behaviour. Recreation-related PA had a larger disparity than other domains, with SII at 20.8% (95% confidence interval [CI] -28.4 to -13.1) and RII at 0.58 (95% CI 0.47-0.71). At the educational level, each inequality was observed in work- and recreation-related PA and sedentary behaviour. The higher the participants' educational level, the longer they engaged in recreation-related PA and sedentary behaviour. However, work-related PA was longer at lower educational levels, with RII at 1.90 (95% CI 1.48-2.44). The inequality in recreation-related PA was also relatively large (SII 23.3%, 95% CI -30.9 to -15.7; RII 0.54, 95% CI 0.45-0.66).
Our study revealed significant socio-economic disparities in each PA domain, particularly in recreational PA. These results suggest a widening gap because of the COVID-19 pandemic.

Socio-economic inequalities in health among older adults in China.
This study aimed to explore socio-economic inequalities in the health status of older people in China using the most recent data available.
This was a cross-sectional study.
Data for this study were obtained from the 2018 China Health and Retirement Longitudinal Study, which included 9831 subjects aged 60 years and older. We assessed differences in the prevalence of self-reported health, functional limitations, and chronic conditions by education level and household income level, and then estimated the Slope of Inequality Index (SII) and the Relative Inequality Index (RII) - indexes of the relative magnitude of socio-economic inequalities in health.
We found inequalities in all dimensions of health (self-assessed health status, reported chronic conditions, and physical functional limitations) at the household income level. Physical functional limitations, particularly the ability to perform instrumental activities of daily living, produced greater inequality than other domains, with an adjusted SII of 0.495 (95% CI, 0.467-0.524) and an adjusted RII of 2.129 (95% CI, 1.604-2.653). ADL limitations (adjusted SII, 0.524, 95% CI, 0.473-0.575, adjusted RII, 1.527, 95% CI, 1.027-2.027) and self-measured health (adjusted SII, 0.523, 95% CI, 0.258-0.789, adjusted RII, 1.531, 95% CI, 0.551-2.512) were also clearly different. Inequalities were also found across all health domains in terms of educational attainment. Consistent with inequalities in household income, inequalities were greatest for limitations in the ability to perform instrumental activities of daily living (adjusted SII, 0.581, 95% CI, 0.424-0.739, adjusted RII, 3.699, 95% CI, 3.642-3.757). Relative inequalities in limitations in activities of daily living (adjusted SII, 0.676, 95% CI, 0.560-0.792, adjusted RII, 2.587, 95% CI, 2.392-2.784) and self-rated health (poor/very poor) (adjusted SII, 0.647, 95% CI, 0.617-0.677, adjusted RII, 2.406, 95% CI, 2.224-2.587) were also higher.
Our study shows significant socio-economic differences in the areas of self-rated health, functional limitations, and reported chronic diseases, particularly in the area of IADL limitations. These inequalities need to be explicitly addressed and vulnerable subgroups should be targeted to reduce the socio-economic disparities.

Socioeconomic inequalities in sport participation: pattern per sport and time trends - a repeated cross-sectional study.
Sport participation is an important component of a healthy lifestyle and is known to be more common among privileged individuals. However, few studies examined socio-demographic patterns of participation by type of activity. This study aims at quantifying socio-economic inequalities in sport participation by sport type, and to analyse their trend over 15 years.
We used 2005-2019 data from the Bus Santé study, a yearly population-based cross-sectional survey of Geneva adults. Sport participation was defined as reporting at least one sporting activity over the previous week; educational level, household income and occupational position were used as indicators of socio-economic position. Socio-economic inequalities in sport participation, and their trend over time, were examined using the relative and slope indexes of inequality (RII/SII).
Out of 7769 participants (50.8% women, mean age 46 years old), 60% participated in a sporting activity. Results showed that the higher the socioeconomic circumstances, the higher the sport participation (RII = 1.78; 95% Confidence Interval (CI): 1.64-1.92; SII = 0.33; 95%CI: 0.29-0.37 for education). Relative inequalities varied per sport e.g., 0.68 (95%CI: 0.44-1.07) for football and 4.25 (95%CI: 2.68-6.75) for tennis/badminton for education. Yearly absolute inequalities in sport participation tended to increase between 2005 and 2019 for household income, especially among women and older adults.
We observed strong socio-economic inequalities in sport participation in Geneva, with different magnitude depending on the sport type. These inequalities seemed to increase over the 2005-2019 period. Our results call for tailored measures to promote the participation of socially disadvantaged populations in sporting activities.

Socioeconomic inequalities in toothbrushing behaviours in young children: a children's lifestyle survey in a representative population of A city, Okinawa prefecture, Japan.
We have less understanding of which socioeconomic status (SES) indicators may be reflective of latent socioeconomic inequalities in toothbrushing behaviours, especially finishing-toothbrushing by parents in young children. The aim of this study was to reveal the socioeconomic inequalities in children's toothbrushing and finishing-toothbrushing by parents and if it varies by SES indicators.
We used data from 'Survey on Children's Life' conducted by A city of Okinawa Prefecture, Japan. The multiple imputed data of 902 (boys, 453) included self-reported children's toothbrushing behaviour and finishing-toothbrushing by parents in three-to six-year-old children. SES was assessed using self-reported household income and parental educational attainment. Absolute and relative inequalities in toothbrushing behaviours were quantified using the slope index of inequality (SII) and relative index of inequality (RII), respectively.
There were significant absolute and relative inequalities of children's toothbrushing for household income (SII and RII were 0.241 and 2.73, respectively), of finishing-toothbrushing by parents for household income (SII and RII were 0.133 and 3.28, respectively), and educational attainment (SII and RII were 0.166 and 5.55, respectively). The same inequality trends were observed after adjusting for covariates (child's age and sex, family structure, breakfast and dinner frequency, and sleep duration).
Socioeconomic inequalities in children's toothbrushing and finishing-toothbrushing by parents varied according to SES indicators.
