IJCM_172A: Risk Scoring of Type 2 Diabetes Mellitus and Coverage of Screening Services through Primary Health Care System among Adults in a Block of Murshidabad District, West Bengal

Abstract

Background: Type 2 diabetes is a major public health challenge. Indian Diabetes Risk Score (IDRS), a simple and cost-effective tool consisting of two modifiable (waist circumference, physical activity) and two non-modifiable risk factors (age, parental history) for diabetes, can be easily applied in mass screening programmes. Opportunistic screening for diabetes among individuals aged = 30 years is being done under the programme for Prevention and Control of Non-communicable Diseases. Objective: To assess the risk of type 2 diabetes mellitus using IDRS, coverage of screening services for diabetes through the primary health care delivery system and to identify their correlates. Methodology: : A descriptive, cross-sectional study was conducted in a block of Murshidabad district, West Bengal during September to November 2023 among permanent residents aged = 30 years on a calculated sample of 300 selected through multi-stage sampling. Required data were collected by interviewing the study subjects using pre-designed, pre-tested schedule including IDRS, reviewing medical records and measuring waist circumference. Analysis was done using SPSS-20. Results: Among 300 participants, 40.7% had high risk; 54% and 5.3% had moderate and low risk of diabetes respectively according to IDRS. In multivariable analysis, age =35 years (AOR 18.10, 95% CI 5.07-64.66), female gender (AOR 2.36, 95% CI 1.40-4.00) and being in joint family (AOR 3.53, 95% CI 1.77-7.04) were significant correlates for high-risk category according to IDRS. Only 67% were screened for diabetes within last six months, of which 89% were through primary health care delivery system. Screening status varied significantly by age group (OR 3.81, 95% CI 1.98-7.35) and IDRS risk categories (OR 1.72, 95% CI 1.06-2.80). Conclusion: Alarmingly substantial proportion of people in the area are at high/moderate risk of diabetes coupled with low opportunistic screening coverage, which highlights the need for intensive behaviour change communication and stronger service delivery.
