Socioeconomic status as the strongest predictor of self-rated health in Iranian population; a population-based cross-sectional study

Does adult socioeconomic status mediate the relationship between adolescent socioeconomic status and adult quality of life?

Objective

This study aimed to determine the association between adolescent socioeconomic status (father's education and adolescent subjective socioeconomic status) and adult quality of life and the mediation roles of adult socioeconomic status, social capital and lifestyle (physical activity and exposure to smoke) among the "Tehran University of Medical Sciences Employees Cohort (TEC) Study" participants.

Method

Data of 4455 participants were derived from the Tehran University of Medical Sciences Employees Cohort (TEC) Study. In this study, the World Health Organization quality of life-BREF, the World Bank's Integrated and the International Physical Activity Questionnaire were used. Data were analyzed with structural equation modeling using SPSS Amos 24.0 program.

Results

The mean age of the participants was 42.31 years (SD: 8.37) and most of the subjects were female (60.7%). Correlation analysis results revealed that, quality of life had a significant and positive association with adolescent subjective socioeconomic status (r = 0.169, p < 0.01) and father's education (r = 0.091, p < 0.01). A mediation model testing the direct relationship between adolescent socioeconomic status and adult socioeconomic status and quality of life, showed a positive relationship between adolescent subjective socioeconomic status (β = 0.229, p < 0.001) and father's education (β = 0.443, p < 0.001) with adult socioeconomic status. Adult socioeconomic status was positively related to quality of life (β = 0.205, p < 0.001). Adult socioeconomic status mediated the relationship between adolescent subjective socioeconomic status (β = 0.047, p < 0.01) and father's education (β = 0.091, p < 0.01) with quality of life. While adult socioeconomic status fully mediated the relationship between the father's education and quality of life, it partially mediated the adolescent subjective socioeconomic status-quality of life association. Other variables such as social capital and lifestyle did not have mediator role in a mediation model.

Conclusion

This study provides the evidence for the role of adult socioeconomic status as a partial mediator between adolescent subjective socioeconomic status and quality of life. Therefore, there are several unknown mediators other than adult socioeconomic status that need to be explored in future studies.

Review of the effect cultural capital and subjective socioeconomic status on life satisfaction in Iran: the mediating role of health-promoting lifestyle and the moderating role of ethnicity

INTRODUCTION

Health-promoting lifestyle can leads to improving the quality of life, life satisfaction, well-being and reducing the burden of health care in the society. This study was carried out to investigate the mediating role of health-promoting lifestyle and moderating role of ethnicity in the effect of cultural capital and subjective socioeconomic status on life satisfaction in Iran.

METHODS

This cross-sectional study was conducted with 800 respondents in the cities of Kermanshah with Kurdish ethnicity and Tabriz with Azeri ethnicity. The data gathering tool was a questionnaire in five section including demographic checklist, cultural capital questionnaire (2015),Diener's life satisfaction scale, and health-promoting lifestyle questionnaire (HPLP II), and socioeconomic status scale. Data were analyzed by SPSS and AMOS software.

RESULTS

Life satisfaction had the highest correlation with the objective dimension of cultural capital (p < 0.001 r = 0.298). The direct standardized coefficient of the path of cultural capital to health-promoting lifestyle was 0.44 (P < 0.001). Also the direct standardized coefficient of cultural capital on Life satisfaction was 0.04 that was not significant. The standard coefficient of the path of cultural capital on life satisfaction through health-promoting lifestyle was 0.27(P < 0.001). Ethnicity variable did not moderate the effect of cultural capital on life satisfaction (p > 0.05).

CONCLUSION

The results of this study showed that paying attention to the concept of health-promoting lifestyle is a necessity to affect life satisfaction. It can play a role as a mediator for the path of cultural capital and socio-economic status on life satisfaction. This study also showed the role of ethnicity as a moderating variable in the relationship between socio-economic status and health-promoting lifestyle.

Population attributable risk fraction of modifiable risk factors associated with poor self-rated health among children and adolescent; the CASPIAN-V study

BACKGROUND

We aimed to determine the population attributable risk fraction (PARF) of the risk factors for poor SRH in Iranian children and adolescents.

METHOD

This was a nationwide cross-sectional study conducted in 2015 among 14,400 students aged 6-18 years, living in 30 provinces of Iran. Data were collected using global school health survey questionnaire. Logistic regression was employed to determine the adjusted association of modifiable risk factors with SRH. We used average PARF to determine the preventable proportion of poor reported SRH.

RESULTS

Of 14,400 recruited students, data on 13,983 subjects were analyzed in current study. The mean (SD) age of participants (n = 13,983) was 12.3 (3.16) years, and 49.3% were female. Poor SRH was reported in 19% of subjects. In total, 77% of poor reported SRH in Iranian children and adolescents could be attributed to insufficient daily sleep duration, physical injury, lack of close friend, dissatisfaction with family relationship, and the lack of a companion to share personal problems. We also found that physical pain had the largest PARF (32.4%) followed by anxiety (26.1%) and un-satisfaction with family relationship (5.2%).

CONCLUSION

The established physical and social support factors of poor SRH were associated with a remarkable proportion of poor SRH in the Iranian pediatric population. Changing the children's risk factor profile to the lowest physical risk factor as well as reducing the anxiety level and preventing from physical painsmay significantly improve the SRH of children and adolescents.

The Impact of Family Income on Body Mass Index and Self-Rated Health of Illiterate and Non-illiterate Rural Elderly in China: Evidence From a Fixed Effect Approach

Background: Rural communities worldwide are experiencing the most significant levels of aging. Most rural elderly have no stable pension, and leading family income plays an indispensable role in the life security of rural elderly. This study aims to investigate whether the association between annual family income per capita and body mass index (BMI) and self-rated health (SRH) in rural elderly is moderated by education during fast economic development.

Methods: We chose the fixed-effects model to analyze the impact of the annual family income per capita change on BMI and SRH based on a large, nationally representative longitudinal dataset of rural respondents aged above 60 of the China Family Panel Studies (CFPS) from 2010 to 2018.

Results: Six hundred and fifty-eight were eligible for inclusion in our analysis in CFPS. The median age of participants was 65 years in 2010, and 379 (57.60%) participants were male. Self-rated health increased with higher the logarithmized family income per capita among the rural illiterate elderly (β = 0.0770; 95% CI = 0.0065–0.1473). Body mass index increased with higher the logarithmized family income per capita among the rural elderly (β = 0.1614, 95% CI: 0.0325–0.2903), and it was more evident among the illiterate elderly (β = 0.2462, 95% CI: 0.05519–0.4372).

Conclusion: Family income has an impact on BMI and SRH moderated by education level among rural elderly in China. These results contribute to developing more targeted strategies in the context of a developing country. In addition, it also reminds us to consider the differences in the educational level of the elderly in rural areas when examining the relationship between family income and health.

Relationship between Employment Type and Self-Rated Health among Korean Immigrants in the US: Focusing on Gender and Number of Years in the US

Although Korean immigrants report worse self-rated health and a higher self-employment rate than other Asian immigrant groups, the relationship between their employment type and self-rated health is understudied. This study examines the relationship between employment type and self-rated health among Korean immigrants in the US. Survey data of 421 first-generation working-age (18-64 years old) Korean immigrants in the New York-New Jersey area were analyzed. The self-administrated survey questionnaire included 39 items (e.g., sociodemographic characteristics, self-rated health, and health insurance status). A logistic regression analysis was conducted to examine the relationship between the dependent variable-self-rated health (e.g., bad/not bad vs. good/very good)-and independent variable-employment type (e.g., work at non-ethnic firms, work at co-ethnic firms, self-employed, and unemployed)-by focusing on differences regarding gender and number of years living in the US. Self-employed and unemployed Korean immigrants were less likely to report good health compared to those working in non-ethnic firms. After controlling for sociodemographic characteristics (age, gender, marital status, education, health insurance status, membership in any Koran association, religion, and English proficiency), the relationship between employment type and self-rated health remained significant among female and recent Korean immigrants. More worksite interventions by occupational health nurses that target self-employed Korean immigrants, especially women and recent immigrants, are necessary.
