Heart Disease and Cancer Cases - CHINA
In China, over the past 30 years, the incidence of cardiovascular disease (CVD) has increased to a great extent. According to the Journal of Geriatric Cardiology, 2017, "in 2014, the mortality rate due to cardiovascular disease was 295.63 per 100,000 people in rural areas and 261.99 per 100,000 people in urban areas". Cardiovascular diseases (CVDs) are commonly known as heart disease.
In China, cancer is the leading cause of death with increasing rate of incidence and mortality each year. As per A Cancer Journal for Clinicians, 2016, the total number of estimated new cancer cases in China was 4,292,000 in 2015. The number of cancer deaths was estimated to be 2,814,000, with lung cancer being the most common cancer as well as the leading cause of death due to cancer.
I have filled the figures based on my findings and calculation in the google spreadsheet.
FINDINGS & CALCULATION
Heart Disease cases in China
Number of patients with heart disease or Cardiovascular Disease (CVD)
In 2010 = 230 million or 230,000,000
In 2014 = 290 million or 290,000,000
There are no hard data available for the years the 1990s and 2000s. So, I have drawn rough estimation for the years 1995 and 2005 with the help of population statistics in China.
China population in
According to the World Heart Federation, "it is estimated that one in five adults in China has a cardiovascular disease".
And, according to the figures for China Demographics Profile 2018, the total number of adults in China,
So, the total percentage of adult population, age 15 & above would be = 82.85%
Keeping the above percentage as fixed, I have used this data to estimate a rough figure for the number of adults (age 15 & above) in China for previous years (1995 & 2005).
The number of adults in China in the
year 2005 = 1,321,623,490 x 82.85% = 1,094,965,000
year 1995 = 1,239,940,004 x 82.85% = 1,027,290,000
As we know that one in five adults in China has a cardiovascular disease, the total number of people with cardiovascular disease for the year
2005 = 1,094,965,000 / 5 = 218,993,000
1995 = 1,027,290,000 / 5 = 205,458,000
Also, I have estimated the figures applying the above method for the year 2010 to check the validity of the estimated figures.
The number of cases with cardiovascular disease came about 225,311,400 for the year 2010 using the above method which seems to be fine as a rough estimate.
Cancer cases in China
I found the total number of cancer patients in the year 1998 whereas, the data for the years 2000s and the year 2010 to 2017 could not be found in research papers or reports and articles by health organizations. However, after an extensive search, I found the number of newly diagnosed cancer cases in the year 2000 and year 2015. Additionally, during my research, I have analyzed that in case of cancer, each year the number of newly diagnosed cases and the number of deaths due to cancer have been estimated and not the total number of patients carrying cancer. I found several articles and research studies revealing the number of newly diagnosed cancer cases and the number of deaths due to cancer in a particular year.
Number of patients with cancer,
In 2015 = 4,292,000 (newly diagnosed cases)
In 2000 = 2,100,000 (newly diagnosed cases)
In 1998 = 1,395,000
As requested, I have filled the spreadsheet with required statistics for the number of diagnosed heart disease and cancer cases in China.
