Abstract
Background & objectiveNoncommunicable Disease (NCD) risk factors are on the rise and often linked to the adoption of modern lifestyles. This study explores NCD risk factors in a rapidly modernising indigenous population in Kerala, the Kani tribe. MethodsA representative sample of 298 adults of the Kani tribe in Thiruvananthapuram district was studied using the WHO stepwise framework for surveillance of NCD risk factors. Descriptive, bivariate and multivariable analysis were done using the R statistical package. ResultsPrevalence of hypertension (48.3%), use of tobacco (81.5%) and alcohol consumption (36.2%) were found to be higher in the Kani tribe compared to the general population in Kerala. Abdominal obesity (22.1%) is found to be higher in Kani tribes compared to other tribal groups in India. The physical inactivity level (9.7%) was similar to urban Kerala and higher than many other tribes in India. Hypertension was scientifically associated (p<0.05) with higher age, male sex, low education levels, and tobacco intake among them. On multivariable analysis, age and alcohol consumption were found to be the prominent risk factors for hypertension and high education level was found to be a protective factor. ConclusionThe major modifiable NCD risk factors were found to be higher among the people of the Kani tribe compared to the general population in Kerala. Physical inactivity level was comparable to urban Kerala, and obesity rates were higher than many other tribal communities in India. The findings warrants targeted action in these vulnerable communities for effective control of the noncommunicable epidemic.
