Association of low educational status with microvascular complications in type 2 diabetes: Jaipur diabetes registry-1

Abstract

Objective: To determine the association of educational status (ES), as a marker of socioeconomic status, with the prevalence of microvascular complications in diabetes. Methods: Successive patients (n = 1214) presenting to our centre were evaluated for sociodemographic, anthropometric, clinical, and therapeutic variables. Subjects were classified according to ES into Group 1 (illiterate, 216); Group 2 (<primary, 537), Group 3 (<higher secondary, 312), and Group 4 (any college, 149). Descriptive statistics are reported. Results: Mean age of patients was 52 +- 10 years, duration of diabetes 7 +- 7 years, and 55% were men. Prevalence of various risk factors was smoking/tobacco 25.5%, obesity body mass index >25 kg/m ² 64.0%, abdominal obesity 63.4%, hypertension 67.5%, high fat diet 14.5%, low fruits/vegetables 31.8%, low fibre intake 60.0%, high salt diet 16.9%, physical inactivity 27.5%, coronary, or cerebrovascular disease 3.0%, and microvascular disease (peripheral, ocular or renal) in 20.7%. Microvascular disease was significantly greater in illiterate (25.9%) and low (23.6%) compared to middle (15.0%) and high (14.7%) ES groups (P < 0.05). Age- and sex-adjusted logistic regression analysis revealed that in illiterate and low ES groups respectively, prevalence of smoking/tobacco use (odds ratio 3.84, confidence intervals 2.09-7.05 and 2.15, 1.36-3.41); low fruit/vegetable (2.51, 1.53-4.14 and 1.99, 1.30-3.04) and low fibre intake (4.02, 2.50-6.45 and 1.78, 1.23-2.59) was greater compared to high ES. Poor diabetes control (HbA1c >8.0%) was significantly greater in illiterate (38.0%), low (46.0%) and middle (41.0%) compared to high (31.5%) ES subjects (P < 0.05). Conclusions: There is a greater prevalence of the microvascular disease in illiterate and low ES diabetes patients in India. This is associated with the higher prevalence of smoking/tobacco use, poor quality diet and sub-optimal diabetes control.
