Mineral imbalance in the body may significantly contribute to the development and course of hypertension. In this paper, blood pressure figures have been linked to the levels of Fe, Ca, Mg, Zn, Cu, Na and K in hair. The research sample was composed of young men (n = 91) aged 13-21, from the town of Mafinga, Iringa District, Tanzania. The data collected included their age, tribal background and weekly diet. Based on body mass index, the participants were categorised into pre-defined subgroups. To examine how the minerals in question affect blood pressure, correlation analysis and multiple ridge regression analysis were performed. Analysis of ridge regression findings for the researched group (n = 91) shows that the minerals under scrutiny account for systolic blood pressure variation in 13 % and in 15 % for diastolic blood pressure variation. After including two additional variables-calendar age and body mass index-in regression analysis, the ultimate coefficient of determination (R (2)) changes for systolic blood pressure and remains the same for diastolic blood pressure (R (2) = 0.194 and R (2) = 0.156, respectively). Nutritional analysis shows that the students included in the study received insufficient calories per day (1,500-2,200 kcal). The group of students with abnormal blood pressure were not aware of their poor health. Research findings may result from progressive environmental changes and poor nutrition in terms of food quantity and quality, which had an impact on the subjects' blood pressure. Hair analysis used to determine mineral content in the body may be an auxiliary tool in identifying the links between factors leading to the development of hypertension.
体内矿物质失衡可能会显著促进高血压的发展和病程。在本文中,血压数值已与头发中的铁、钙、镁、锌、铜、钠和钾水平相关联。研究样本由来自坦桑尼亚伊林加地区马芬加镇的13 - 21岁年轻男性(n = 91)组成。收集的数据包括他们的年龄、部落背景和每周饮食。根据体重指数,参与者被分为预先定义的亚组。为了研究上述矿物质如何影响血压,进行了相关性分析和多重岭回归分析。对研究组(n = 91)的岭回归结果分析表明,所研究的矿物质分别占收缩压变化的13%和舒张压变化的15%。在回归分析中纳入另外两个变量——日历年龄和体重指数后,收缩压的最终决定系数(R²)发生变化,而舒张压的最终决定系数保持不变(分别为R² = 0.194和R² = 0.156)。营养分析表明,纳入研究的学生每天摄入的热量不足(1500 - 2200千卡)。血压异常的学生群体并未意识到自己的健康状况不佳。研究结果可能源于环境的逐渐变化以及食物数量和质量方面的营养不良,这对受试者的血压产生了影响。用于确定体内矿物质含量的头发分析可能是识别导致高血压发展的因素之间联系的辅助工具。
