Abstract P023: Burden of Hypertension, Prehypertension and Associated Lifestyle Risk Factors Among Tribals in Tribal and Urban Areas in the Northern State of Sub-Himalayan Region of India
Introduction: Rapid urbanization has been associated with high prevalence of hypertension in indigenous populations .
Hypothesis: The study is based on the hypothesis of the effect of lifestyle changes on hypertension in nomadic tribes settled in urban areas .
Objectives: To determine the prevalence of hypertension and evaluate associated risk factors in traditional tribal individuals residing in tribal areas and migrated tribals in urban areas .
Methodology: It was a population based cross sectional study .The population studied were the tribals , representing the traditional people settled in mountainous terrain centuries ago leading a nomadic life and migrating from upper reaches of Himalayas to Himalayan foothills during winters .Some of them settled in urban areas .
Men and women above 20 years were considered as eligible subjects . A probabilistic proportionate sampling method was used.The final sample of 8000 individuals consisting of 4000 subjects each of tribal and urban tribals were evaluated which included demographical profile , BMI , central obesity ,blood pressure , fasting blood sugar , oral glucose tolerance test using 75 gm glucose and physical activity .
Results: The urban tribals were engaged in white collar and business jobs (33%) vs 11.1% in tribal tribals(p=0.00) .Urban tribals had mild physical activity in 19.3% vs 8.6 % in tribal tribals(p=0.00) whereas tribal tribals had significantly more heavy physical activity(23%) vs 7.3% in urban tribals(p=0.00) In urban tribals central obesity was seen in 59% of cases vs 43.3% in tribal tribals(p=0.00).Urban tribals had statistically more (29.3%) overweight individuals as compared to 13.3% in tribal tribals(p=0.00).Stage 1 hypertension and stage 2 hypertension was seen in 22.8% and 5.3% resspectively in urban tribals which is statistically higher than seen in tribal tribals(10.2 % and 0.9% respectively)(p=0.00)The age distribution of prevalence of hypertension was high amongst urban tribals of more than 65 years(54%) followed by 51 to 56 years(48.3%) and 36 to 50 years of age(34.2%).Diabetes mellitus was significantly higher in urban tribals(7.8%) vs 3.9% in tribal tribals(p=0.00).Prehypertension and impaired fasting glucose was statistically more often seen in tribal tribals(78.8% and 2.4%) vs 58.2% and 0.7% respectively in urban tribals(p=0.00)
Conclusion: In conclusion prevalence of hypertension , central obesity,diabetes mellitus and physical inactivity was higher in urban tribals .On contrary pre hypertension and impaired fasting glucose was significantly higher in tribals in tribal areas which necessitate a need for early preventive intervention .
