Risk factors for the development of essential hypertension in a Mongolian population of China: a case-control study

Abstract

ABSTRACT. Lifestyle, habits, diet, and genetics are all important factors associated with the prevalence of hypertension. Many association studies have been performed in the Chinese Han population, whereas data explaining the high prevalence of hypertension in the Mongolian population remain scarce. In the present study, we aimed to determine the factors associated with the development of essential hypertension in Mongolians. A total of 194 hypertensive cases and 201 controls from Dongwu County were enrolled in the study. Demographics, anthropometric and blood biochemical parameters, food intake, lifestyle, habits, education, occupation, and family history were recorded for each subject. Genotype and allele frequencies of six single nucleotide polymorphisms (SNPs) of the kallikrein 1 (KLK1) gene were also examined. Mean body mass index, waistline, hipline, blood sugar, blood urea nitrogen, creatinine, uric acid, total cholesterol, triglyceride, and low-density lipoprotein levels were all significantly higher in the hypertensive group (P < 0.01). Hypertensives consumed less milk, vegetables, and fruits, and had higher cigarette, alcohol, and salt intake (P < 0.05). There were also less regular physical exercisers and manual workers among the hypertensive group (P < 0.05). The mean inheritance rank of the hypertensive group was higher than that of controls (P < 0.05). There were no differences in the distribution of genotype and allele frequencies of the six SNPs between the hypertensive and control groups (P > 0.05). These results suggest that dietary history and habits have the most important influence on the development of essential hypertension in the Mongolian population.

Prevalence and associated factors for pterygium in Han and Mongolian adults: a cross-sectional study in inner Mongolian, China

“…Previous studies have found that the Chinese have lower BMI and higher BF% [37]. There were great differences in the diet and living habits of the Han and Mongolian ethnicities [38,39]. In comparison to the Han ethnicity, Mongolians had a higher meat and salt intake and a lower intake of fruits and vegetables, which meant that Mongolians ingested more fat and protein [40].…”

Occupational Disparities in the Association between Self-Reported Salt-Eating Habit and Hypertension in Older Adults in Xiamen, China

“…Excessive sodium is a risk factor for hypertension which has been well documented in epidemiological [ 6 , 7 ] and clinical [ 8 , 9 ] studies. A previous meta-analysis included nine randomized, controlled trials with 14 comparisons between low and normal sodium intake groups [ 8 ].…”

“…The demographic and clinical characteristics between EH and NT showed that age, AC, BMI, TG, FBG were the risk factors, while HDL was the protective factor for EH, findings which were consistent with other researchers. 21 , 22 …”
