Influence of Social Determinants of Health on the Quality of Life of Older Adults in Europe: A Sex Analysis

Introduction

The global aging population poses challenges for society such as health inequalities among older persons and between genders.

Objectives

To determine how Social Determinants of Health (SDH) influence the quality of life (QoL) of individuals over 50 years old in various European countries, taking a gender perspective in a longitudinal study.

Materials and methods

Sample of 11,493 individuals from 13 European countries from Waves 5 (2013), 6 (2015), and 7 (2017) of the SHARE study. Instruments: CASP-12 (QoL), EURO-D (depression), SDH: gender, age, educational level, socioeconomic status, ethnicity, place of residence, and European region. Sociodemographic and clinical variables. Statistical analysis: Bivariate and multivariate mixed linear models.

Results

The bivariate analysis showed higher economic hardship and lower education in women compared to men. The CASP-12 score was higher in men than in women. In the multivariate analysis, the variables associated with lower QoL scores among men and women from Wave 5 to Wave 7 were: (β:-0.196, 95% CI: -0.345; -0.047) vs (β:0.038, 95% CI: -0.122; 0.197); economic hardship; and the European region between South and North (β: 2.709, 95% CI: 2.403; 3.015) vs men (β: 2.224, 95% CI: 1.896; 2.551).

Conclusions

The main SDH associated with poorer QoL were female gender, advanced age, economic hardship, educational level, and geographic location within Europe. Depression in women and in Southern Europe were associated with a decrease in QoL scores.

Determinants of health literacy in the general population: results of the Catalan health survey

Background

Health Literacy (HL) is the knowledge and competence to access, understand, appraise, and apply health information for health judgment. We analyze for the first time HL level of Catalonia’s population. Our objective was to assess HL of population in our area and to identify social determinants of HL in order to improve the strategies of the Healthcare Plan, aimed at establishing a person-centered system and reducing social inequalities in health.

Methods

This was a cross-sectional study based on the Health Survey for Catalonia (ESCA, Enquesta de Salut de Catalunya), which included the 16 items of the European Health Literacy Survey Questionnaire (HLS-EU-Q16). The statements in the questionnaire cover three different health literacy domains: Health Care, Disease Prevention, and Health Promotion. HL was categorized in three levels: Sufficient, Problematic and Inadequate. Chi-square tests were performed to compare the percentages of subjects with adequate or inadequate HL across sociodemographic and health-related variables. Variables showing significant differences were included in a stepwise logistic regression to predict inadequate HL level.

Results

The questionnaire was administered to 2433 subjects aged between 15 and 98 years old (mean of 45.9 years, SD 18.0). Overall, 2059 subjects (84.6%) showed sufficient HL, 250 (10.3%) inadequate HL, and 124 (5.1%) problematic HL, with no significant differences between men and women (p = 0.070). A logistic regression analysis showed that low health literacy is associated with a lower level of education (OR 2.08, CI 95% 1.32–3.28, p = 0.002), low socioeconomic status (OR 2.11, CI 95% 1.42–3.15, p <  0.001) and a physical limitation to perform everyday activities (OR 2.50, CI 95% 1.34–4.66, p = 0.004). We also found a more modest association with low physical activity, having a self-perceived chronic disorder and performing preventive activities.

Conclusions

Catalonia has a high percentage of subjects with sufficient HL. Education level, socioeconomic status and physical limitations were the factors with the strongest contribution to inadequate or problematic health literacy. Although these results are likely to be country-specific, the factors identified will allow policymakers of areas with similar socioeconomic profiles to identify groups with high risk of problematic or inadequate HL, which is essential for a successful patient-centered model of care.
