Eom, Yang, Oh, Lee, Lee, Kim, Lee, Im, Yim, Oh, Nam, and Park: Association of Educational Level and Socioeconomic Status with Glucose Metabolism

Abstract

Background

The objective of the present study was to examine the association of educational level and socioeconomic status with glucose metabolism including prediabetes.

Methods

This cross-sectional study subjects were 882 (mean age: 51.0 ± 13.4 years, M:F = 241:641) without diabetes, aged more than 20 years and residing in Whasu 2 dong in Incheon. We classified them into three levels according to their educational level: primary (illiterate or up to elementary school), secondary (middle school or high school) and tertiary (university), and into three levels according to their socioeconomic status by self reported questionnaire: low, middle and high. Subjects were diagnosed as three groups (normal, prediabetes and diabetes) by American Diabetes Association criteria using 75 g oral glucose tolerance test. The association of educational level and socioeconomic status with glucose metabolism was analyzed.

Results

The number of normal group was 300 (34.0%), that of prediabetes was 470 (53.3%) and that of diabetes was 112 (12.7%). In women, the proportion of primary educational group was larger than that of secondary educational group in diabetes (Odds ratio [OR] = 1.88; 95% confidence interval [CI]: 1.01-3.51) and larger than that of tertiary educational group in prediabetes ([OR] = 2.00; [CI]: 1.06-3.78). But socioeconomic status did not have the statistical association with glucose metabolism in women. Also both educational level and socioeconomic status had no statistical association with glucose metabolism in men.

Conclusions

The proportion of low educational level is larger in prediabetes and diabetes compared with normal group in women.

Group 1 (Education group 1) = university; Edu. Group 2 (Education group 2) = high school or middle school; Edu. Group 3 (Education group 3) = up to elementary school or illiterate Exercise group = group. exercising over 30 minutes at a time and over 3 times per week with moderate or severe intensity; SES Group 1 (Socioeconomic group 1) = high economic status; SES Group 2 (Socioeconomic group 2) = middle economic status; SES Group 3 (Socioeconomic group 3) = low economic status. For each variable, the percentages reflect the total number of patients for whom data were available.
