Global Sodium Consumption and Death from Cardiovascular Causes


The presented research article is aimed to articulate the negative impacts of high degree of sodium intake at global level. The research undertaken in the article quests for revealing risk factor for cardiovascular disease due to heavy intake of sodium by global population. In addition to this research study also aims to reveal the dose-response relationship between sodium intake and blood pressure with the help of Meta analysis.

Description of Methods

For the purpose of accomplishing the research objectives, a survey regarding urinary excretion diet of adult person from 66 countries have been taken into account. In order to retrieve some crucial assumptions from the data collected, Meta analysis of 107 different interventions trails done on randomized basis. In the Meta analysis of cohort, impact of blood pressure over cardiovascular mortality has been revealed. In addition to this, comparative risk assessment method has also been used in the work for the purpose of revealing the impact of existing sodium intake over cardiovascular functions of human being. In this regard, intake of 2.0 g. of sodium has been taken in account as reference dose for the trial undertaken for the research process. In this way, it can be stated that the researcher has undertaken different scientific and validate methods for the purpose of accomplishing different research objectives.

Description of Results

Researchers have found that in the year 2010, the consumption of sodium was 3.95g per day. The regional mean for this observation was ranged from 2.18 to 5.51 gram per day. In addition to this, in that year about 1.65 million annual deaths due to cardiovascular diseases have been registered. These all the disease was due to the intake of sodium above the pre decided reference level. It has also been reflected that about in low and middle income countries 84.3% of deaths were registered due to cardiovascular disease. About among total cardiovascular deaths across the world, 61.9% were males while 38.1% were female. In addition to this, the results of trial have also reflected that the level of above reference level sodium intake was highest inGeorgia and lowest in Kenya.


Critical Analysis

The methods used by the author in the research work are quite practical and scientific. However, no scope of undertaking different literatures has been considered in the research work. Practical trials are effective for the purpose of providing clear status of the problem and analysis, but this method does not elaborate the theoretical vaiblity of the context and results. In this regard, the research work can be proved more effective if some literature review would have been included in the work. In addition to this, the scope of the research process undertaken is quite vast as observations are taken from 66 different countries. Although the research observations considered in the work are quite comprehensive, yet from the perspective of time and efforts of research the large sample size cannot be considered effective. In this way, the research should try to take different number of samples from limited numbers of countries from different income group. In this way, it can be analyzed critically that there are some factors in the paper, which can be improved in similar types of research work in future.
