[Relationship study of angiotensin II type 1 receptor gene A1166C polymorphism, food consumption and behavior on hypertension in Kazakh group, Xinjiang].
OBJECTIVE
To investigate the polymorphism of angiotensin II type 1 receptor (AT(1R)) gene A1166C and environmental factors on hypertension of Kazakh people.


METHODS
Through the random program of SPSS 13.0, 220 cases were randomly selected from the confirmed hypertension patients, and 220 cases with normal blood pressure were selected as control group. All cases were investigated through the questionnaire and the related indexes were measured. By polymerase chain reaction (PCR) method, the genotypes were determined.


RESULTS
(1) In hypertension group, the genotype frequency of AA and AC were 78.6% (173/220) and 21.4% (47/220), respectively, compared with control groups' 81.4% (179/220) and 18.6% (41/220), no significant difference was identified between these two groups (chi(2) = 0.537, P > 0.05). In hypertension group, the frequency of A and C allele were 89.0% and 11.0%, respectively, compared with 90.3% and 9.7% in control group. There was no significant difference between these two groups (chi(2) = 0.37, P > 0.05). (2) AC genotype might interact with excessive salt consumption (hypertension group, 31/220, 15.5%; control group 10/220, 4.5%, OR: 4.67, 95%CI: 2.15 - 10.15), overweight (hypertension group, 19/220, 8.6%; control group, 9/220, 4.1%, OR: 6.96, 95%CI: 2.33 - 20.76) and drinking large volume of salty milk (hypertension group, 20/220, 9.1%; control group, 10/220, 4.5%, OR: 2.67, 95%CI: 1.11 - 6.42) which will raise hypertension hazard of AC genotype.


CONCLUSIONS
There is no relationship between the A1166C gene polymorphism of AT(1R) gene and hypertension of Kazakh people. AC genotypes might also interact with food consumption habit and behavior factors and increase the individual risk of hypertension.
