Association between socioeconomic status and cardiovascular risk

Dietary Habits and Dietary Antioxidant Intake Are Related to Socioeconomic Status in Polish Adults: A Nationwide Study

The aim of this study was to estimate dietary habits and dietary antioxidant intake in a Polish adult population in relation to socioeconomic status. The subjects (4774) were participants in the Polish National Multi-Centre Health Examination Survey (the WOBASZ II study) performed in 2013–2014. Socioeconomic status (SES) scores were calculated by multiplying ordinal numerical values assigned to consecutive categories of education level and monthly income per capita in a family. In the Polish adult population, a higher socioeconomic status was significantly associated with a better lifestyle (more physical activity and less smoking), a better health status (lower occurrence of overweight individuals and metabolic syndrome in both genders, and lower occurrence of central obesity, hypertension, and diabetes in women), and better dietary habits, including a higher intake of dietary antioxidants.

Years of life lost due to diseases of the digestive system in Poland according to socioeconomic factors: a cross-sectional study

OBJECTIVES

To analyse years of life lost (YLLs) due to digestive diseases in Poland according to: marital status, education, working status and place of residence.

DESIGN

A cross-sectional study.

SETTING

The study was based on a dataset containing information from death certificates of Poles who died in 2002 and in 2011.

PARTICIPANTS

The analysis covered records with codes K00-K93 according to the International Classification of Diseases and Related Health Problems, 10th Revision.

OUTCOME MEASURES

YLL values were calculated using the Standard Expected Years of Life Lost measure. For each socioeconomic variable, the rate ratio (RR) was calculated as the quotient of YLLs in the less privileged group to the more privileged group.

RESULTS

Among the categories of marital status, the smallest YLL values (per 10 000) were recorded among singles (men: 100.63 years in 2002, 121.10 years in 2011; women: 26.99, 33.33, respectively), and the most among divorced men (657.87, 689.32) and widowed women (173.97, 169.46). YLL analysis according to education level revealed the lowest values in people with higher education (men: 54.20, 57.66; women: 17.31, 18.31) and the highest in people with lower than secondary education (men: 178.85, 198.32; women: 104.95, 125.76). Being economically active was associated with a smaller YLL score (men: 39.93, 59.51; women: 10.31, 14.96) than being inactive (men: 340.54, 219.93; women: 126.86, 96.80). Urban residents had higher YLL score (men: 159.46, 174.18, women: 73.03, 78.12) than rural ones (men: 126.83, 137.11, women: 57.32, 57.56).In both sexes, RR according to education level and place of residence increased, and those according to marital status and working status decreased with time.

CONCLUSIONS

Activities aimed at reducing health inequalities in terms of YLL due to digestive diseases should be primarily addressed to inhabitants with lower than secondary education, divorced and widowed people, urban residents and those who are economically inactive.

How does the risk of cardiovascular death and cardiovascular risk factor profiles differ between socioeconomic classes in Poland: A country in transition

BACKGROUND

Socioeconomic status (SES) is an important factor for cardiovascular diseases (CVD) development. A decline in death rate from CVD among subjects with high SES is observed in developed countries. The aim of this study was to assess differences in cardiovascular risk (CV) between socioeconomic classes in Poland, a country currently in transition.

METHODS

A sample of 15,200 people was drawn. A three stage selection was performed. Eventually, 6170 patients were examined (2013/2014). Data was collected using a questionnaire in face-to-face interviews, anthropometric data and blood tests were also obtained. Education was categorized as incomplete secondary, secondary and higher than secondary school. Monthly income per person was categorized as low (≤ 1000 PLN), medium (1001-2000 PLN) and high (≥ 2001 PLN). Education and income groups were analyzed by prevalence of CVD risk factors and high CVD risk (SCORE ≥ 5%).

RESULTS

Higher education was associated with lower prevalence of all analyzed CVD risk factors (p < 0.001), having the highest income with lower prevalence of hypertension, currently smoking, obesity and lower high density lipoprotein cholesterol. Multivariable analysis showed that frequency of high CVD risk decreased with increasing education level (OR 0.61; 95% CI 0.49-0.76; p < 0.01), a similar favorable impact of higher income on high CVD risk was demonstrated in the whole group (OR 0.81; 95% CI 0.67-0.99; p = 0.04).

CONCLUSIONS

Socioeconomic status is an independent predictor of high CV risk of death. A favorable impact on the prevalence of high CV risk was demonstrated for education and partly for income in the whole group. It may reflect a transition being undergone in Poland, moreover, it predicts how socioeconomic factors may generate health inequalities in other transitioning countries.
