The aim of the study was to examine the association between dietary intake and lifestyle pattern of diabetes patients in Manipur. Tribal and non tribal respondents between 45-64 years of age were randomly selected from the Regional Institute of Medical Sciences (RIMS) Hospital Manipur. Total number of 200 study subjects, 100 tribal and 100 non tribal subjects constituted the study. The information was collected on socio-demographic profile, clinical, anthropometric measurements and dietary intakes of the patients by using interview schedule and 24-hour dietary recall methods. The data were analyzed and tabulated using statistical tools such as frequency, percentage, mean, standard deviation and Pearson’s correlation test. The key results indicate that alcohol consumption, elevated triglycerides levels, low energy, oils and sugar intake were notably linked with the prevalence of diabetes. Additionally, low calcium intake, particularly among non tribal individuals, demonstrated a significant correlation with elevated Fasting Blood Glucose (FBG) levels, suggesting a potential risk factor for Type 2 diabetes. Moreover, low calcium intake among the non-tribal community was associated with increased Post Prandial (PP) test results, indicating a rise in post-meal glucose levels. Notably, tribal energy intake and non-tribal protein consumption were significantly associated with HbA1c levels, reflecting their impact on glycemic control.
