Impact of Socioeconomic Status on Health Behaviors, Metabolic Control, and Chronic Complications in Type 2 Diabetes Mellitus.

ABSTRACT: BACKGROUND:The aim of the study was to assess the impact of socioeconomic status (SES) on health behaviors, metabolic control, and chronic complications in people with type 2 diabetes mellitus (T2DM) from South Korea, a country with universal health insurance coverage and that has experienced rapid economic and social transition. METHODS:A total of 3,294 Korean men and women with T2DM aged 30 to 65 years, participating in the Korean National Diabetes Program (KNDP) cohort who reported their SES and had baseline clinical evaluation were included in the current cross-sectional analysis. SES included the level of education and monthly household income. RESULTS:Lower education level and lower income level were closely related, and both were associated with older age in men and women. Women and men with lower income and education level had higher carbohydrate and lower fat intake. After adjustment for possible confounding factors, higher education in men significantly lowered the odds of having uncontrolled hyperglycemia (glycosylated hemoglobin ?7.5%) (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.43 to 0.91 for highest education; P(trend)=0.048), while higher household income in men significantly lowered the odds of having diabetic retinopathy (OR, 0.59; 95% CI, 0.37 to 0.95 for highest income level; P(trend)=0.048). In women, lower income was associated with a higher stress level. CONCLUSION:Men with lower SES had higher odds of having diabetic retinopathy and uncontrolled hyperglycemia, showing the need to improve care targeted to this population.

Project description:ObjectiveTo evaluate type 2 diabetes mellitus (T2DM)-related direct medical costs by complication type and complication number, and to assess the impacts of complications as well as socioeconomic factors on direct medical costs.DesignA cross-sectional study using data from the region's diabetes management system, social security system and death registry system, 2015.SettingTongxiang, China.ParticipantsIndividuals diagnosed with T2DM in the local diabetes management system, and who had 2015 insurance claims in the social security system. Patients younger than 35 years and patients whose insurance type changed in the year 2015 were excluded.Main outcome measuresThe mean of direct medical costs by complication type and number, and the percentage increase of direct medical costs relative to a reference group, considering complications and socioeconomic factors.ResultsA total of 19?015 eligible individuals were identified. The total cost of patients with one complication was US$1399 at mean, compared with US$248 for patients without complications. The mean total cost for patients with 2 and 3+ complications was US$1705 and US$2994, respectively. After adjustment for socioeconomic confounders, patients with one complication had, respectively, 83.55% and 38.46% greater total costs for inpatient and outpatient services than did patients without complications. The presence of multiple complications was associated with a significant 44.55% adjusted increase in total outpatient costs, when compared with one complication. Acute complications, diabetic foot, stroke, ischaemic heart disease and diabetic nephropathy were the highest cost complications. Gender, age, education level, insurance type, T2DM duration and mortality were significantly associated with increased expenditures of T2DM.ConclusionsComplications significantly aggravated expenditures on T2DM. Specific kinds of complications and the presence of multiple complications are correlated with much higher expenditures. Proper management and the prevention of related complications are urgently needed to reduce the growing economic burden of diabetes.
