Comparative Epidemiological Studies on the Genesis of Hypertension In Nepal

我们已经调查了尼泊尔4个不同地区的不同生活方式的人，从医学、营养、形态和生理角度来看，作为日本-尼泊尔合作的健康科学研究。据说生活在山区的人们在生活中仍然喝盐茶，据说他们每天的食盐消耗量超过15克。本调查旨在了解山区居民的身体成分、血压、血液化学、营养素摄入量和体力活动等方面与以往调查人群的差异。调查对象为173名男性和178名女性，年龄在20岁到84岁之间。身体。身高、体重、估计体脂百分比的皮褶厚度和最大有氧能力(MAP)均为…更有节制。居住在山区的受试者体脂百分比高于丘陵和郊区农村受试者。营养调查结果表明：(1)膳食以大米、豆类和蔬菜为主，偶尔以腌菜为主。(2)所有受试者均习惯性饮用盐茶，每人约1~3升。认为盐茶的含盐量为0.3-0.4%。(3)膳食以高碳水化合物为主，蛋白质摄入量极低，脂肪摄入量略低于日本。(4)蛋白质能量比为7%，低于日本。(5)大多数受试者动物蛋白含量几乎为零，而动物脂肪含量在60%以上，其中大部分来源于藏茶。(6)每公斤体重的能量摄入量为35-45千卡，高于日本人。用半自动血压测量仪连续测量3次血压。分析采用3次连续测量的平均收缩压和舒张压。根据WHO标准将受试者分为3组。临界性高血压和高血压患病率分别为14.2%和32.5%。血压分级无性别差异。山区高血压患病率明显高于以往任何一项研究。虽然高海拔可能是高血压发病率高的原因之一，但仍有必要对此进行进一步的讨论。较少

We have already investigated 4 different areas in Nepal where the people having the different life style from the medical, nutritional, morphological and physiological standpoint of view as the Japan-Nepal collaborative health scientific research. The people living in the mountain areas are said to have still taken salt tea in their life and their salt consumption is said to be more than 15g per day. The purpose of the present investigation is to find out the difference of body composition, blood pressure, blood chemistries, nutrient intakes and physical activities between the people living in the mountain areas and those who had been investigated in the past studies. The identical methods with the previous research will be applied to the present one so that we can compare the data with each other.The subjects investigated were 173 men and 178 women aged from 20 to 84 years. Body. height and weight, skinfold thickness for estimating %fat of the body and maximal aerobic power (MAP) were … More measured. %Fat was higher in the subjects living in the mountain area than in those in the hilly and the suburban villages. However, no significant difference of MAP was found between the subjects in the mountain area and those in the hilly village in all age groups.The following results were obtained from the nutrition survey : (1) The diet mainly consisted of rice, pulses and vegetables, and occasionally of pickles. (2) All subjects were habitually drinking salt tea, the approximate amount ranging from 1 to 3 liters per person. The concentration of salt in salt tea was considered to be 0.3-0.4%. (3) High carbohydrate diet was dominant and the protein intake was extremely low, but the fat intake was slightly lower than that of Japan. (4) Protein energy ratio was 7 %, being lower than Japanese. (5) Animal protein ratio was almost zero in most of all subjects, whereas animal fat ratio was more than 60%, most of which were taken from Tibetan tea. (6) The intakes of energy per kg of body weight were considered to be 35-45kcal, which were higher than those of Japanese.Blood pressure (BP) was measured 3 times consecutively using the semiautomatic BP measuring device. The average of 3 consecutive measurements for systolic and diastolic BP were adopted for the analyses. The subjects were classified into 3 groups according to WHO criteria. The prevalence rates of borderline hypertension and hypertension were 14.2% and 32.5%, respectively. There was no sex difference in the classification of BP. The prevalence rates of hypertension in the mountain area was remarkably higher than those of any other previous studies. Although the high altitudes might be one of the reason for the high incidence of hypertension, further discussion concerning this matter will be necessary. Less
