With the rising incidence of diabetes in India it becomes particularly relevant to ascertain its prevalence and associated factors
in various ethnic groups with different culture and lifestyle. Cross-sectional study was carried out among 603 subjects
between 20-70 years of age to evaluate the relationships between overweight/obesity, diabetes and socioeconomic change among
Tangkhul Nagas. Subjects were divided into five decadal age groups. Height, weight, waist circumference, hip circumference,
random blood sugar level, general and regional obesity indices viz., BMI, WSR and WHR were evaluated. The prevalence of
overweight/obesity among males was 17.6% while among females, it was 27.1%. The prevalence of prediabetes and diabetes
were 10.7% and 2.5% respectively among males. In females, 7.6% were prediabetic and 2.9% were diabetic. Diabetes was found
only among the three oldest age groups. Blood sugar level had positive correlation with age, BMI, WSR with highest correlation
with WHR among obesity indices. The incidence of high sugar and mean sugar level was found higher among centrally obese
subjects. Odds ratio showed high socioeconomic status as significant risk factor for development of overweight/obesity, which
in turn is risk factor for development of high blood sugar. Sugar level was found higher among females, which corresponds to
their higher adiposity level. Tangkhul Nagas has been experiencing socioeconomic and lifestyle change which led to increasing
prevalence of overweight/obesity and high blood sugar, contributing to the escalating global epidemic of obesity and diabetes.
Close associations between socioeconomic status, overweight/obesity, age and blood sugar level was observed.
