From Table 2, a much larger proportion of males (78.9%) smoke daily compared to females (21.1%). Smoking is a well known risk factor for heart disease. Since more males engage in smoking, this leads to the higher number of male deaths from heart disease.

felicity

2025-09-23 03:37:29 UTC

Males have a higher percentage of smoking daily and higher percentage of eating more than 4 servings of processed meat per day than females. And they have a lower never-smoked percentage than females. They generally have a more unhealthy lifestyle than female, which may contribute to a worsening of their disease and lead to a higher death rate.

2025-09-23 03:37:34 UTC

More males die of heart disease, according to Table II, more males smoke daily. Smoking damages blood vessels, and causes the building up of plaque, which will lead to blood clotting and therefore heart disease.

2025-09-23 03:37:46 UTC

The lifestyle of male are mostly having smoking habit in daily and consume more meat than women, female smoke less than male by 30%, so female have a healthier life style than male. Therefore the death rate of male is higher than female

2025-09-23 03:38:04 UTC

Caycee: Since the percentage of male smoking daily (78,9%) is more than the percentage of females (21.1%), and the percentage of males who never smoked (36.9%) is less than the percentage of females (63.1%), it can explain why the mortality for males is higher than that of females for heart disease. This is because smoke contains nicotine and carbon monoxide, which increases the chance of coronary heart disease.

Anwesha

s21j08 — 2025-09-23 03:38:11 UTC

Heart disease kills more males because more males are daily smokers

Naomi

Eugenie Mak

2025-09-23 03:39:40 UTC

Smoking is a major risk factor for heart disease. The number of deaths of males caused by heart disease is more than that of females by 371. In table II, it shows that 78.9% males smoke daily, while only 21.1% females smoke daily. 36.9% males never smoked, while 63.1% females never smoked. This shows that more males smoke daily, and that more males die of heart disease, hence smoking leads to the worsening of their disease.

2025-09-23 03:39:46 UTC

More male smoke daily than female, linking this to table 1, the result is that more male die from heart disease than female, and the mortality rate of male in early ages is higher.

2025-09-23 03:40:15 UTC

More male was killed by heart disease. Table II shows that, 57.8% more males smoke daily than that of the number of females. Male also consume more processed meat. Both of these are examples of unhealthy lifestyle, which contributes to the risk factors of heart diseases, increasing the risk of males having heart diseases.

Jessie Kwok

More male were daily smoker than female, the people who smoke daily have a higher chance of dying from heart diseases, nicotine in cigarettes smoke can lead to an increase in heart rate, constriction of arterioles and formation of blood clots. Carbon monoxide in cigarettes smoke reduces the oxygen carrying capacity of blood and thus less oxygen supplied to cardiac muscles, hence a higher chance of dead .

janis hui

Compared to women, men exhibit higher rates of daily smoking and high processed meat consumption, along with a significantly lower rate of being non-smokers. This tendency towards smoking is whyy men compared to women often experience higher chances of heart disease

2025-09-23 03:41:45 UTC

from table 1, heart disease kills more males than females. from the table, there are more males who smoke daily compared to females (57.8% difference), which increases the risk of heart disease because nicotine in cigarette smoke leads to an increase in heart rate, constriction of arterioles and formation of blood clot.

s21m12 — 2025-09-23 03:41:47 UTC

According to Table 2, 78.9 % of male have a habit of smoking daily, which has a higher percentage of female who smoke daily with 21.1%, countering the amount of death for heart disease with male higher than female.

s21j08 — 2025-09-23 03:44:29 UTC

Colon cancer kills more males because from the table you can infer that more males eat processed meat that contains chemicals that can be harmful if consumed often and may even stimulate mutations..

2025-09-23 03:44:32 UTC

Caycee: Colon cancer kills more males than females, because more males consume more than 4 servings of processed meat than females. Processed meat contains carcinogenic chemicals, which are cancer-causing agents that induce mutations, hence more males die from colon cancer than females

Eugenie

2025-09-23 03:44:37 UTC

Colon cancer kills more males than females. More males eat processed meat as compared to females. Carcinogenic chemicals are formed during the manufacturing and cooking of processed meat, which contributes to the risk of cancer.

2025-09-23 03:44:41 UTC

from table 1, there is a higher mortality rate for colon cancer in males than in females. from table 2, it is seen that males have more servings of processed meat per week than females (15.4% difference). This increases the risk of getting colon cancer because carcinogenic chemicals are formed during the manufacturing of processed meat.

2025-09-23 03:44:56 UTC

Table I shows that more males were killed by colon cancer than that of females. Table II indicates that more male smoke daily and eat more processed meat than females. Processed meat contains more carcinogens, and with males consuming more meat per week, they are exposed to more carcinogens, increasing the risk of mutations happening, therefore increasing the risk of having cancer.

felicity

2025-09-23 03:45:37 UTC

Colon cancer kills more males than females. More males eat more than 4 servings of processed meat per week than females. High consumption of processed meat leads to a higher intake of carcinogenic chemicals into the body, leading to a higher colon cancer death rate.

2025-09-23 03:46:06 UTC

The difference of percentages of male and female of consuming at least 4 servings of processed meat p[er week is small. Thus the numbers of deaths of male and female only have a slight difference. This shows that consuming processed meat directly affects the death rate of colon cancer as processed meat contains many chemicals

2025-09-23 03:46:06 UTC

Males with 57.7% tend to eat more processed meat per week than females with 42.3%. This shows that males are more prone to colon cancer , as processed meat has a a lot of carcinogenic chemicals formed during the manufacturing so it increases the risk of colon cancer.

janis hui

2025-09-23 03:46:21 UTC

from the table, more men consume processed meat than women. since processed meat contains carcinogens, this may damage the dna of the cells lining the colon which causes the cells to multiply uncontrollably or the mutating of cells. This situation may develop tumours and cause colon cancer. thus men die from colon cancer mkre than women

Heidi

s21v02 — 2025-09-23 03:46:28 UTC

Colon cancer kills more males than females. More males have >4 servings of processed meat per week. Processed meat contains carcinogenic chemicals, which contributes to the risk of cancer.

2025-09-23 03:46:38 UTC

Colon cancer kills more males than females. According to Table II, males consumer more processed meat than females. cancer is caused by genetic mutations, the chemicals in the processed meat will damage DNA and stimulate the gentic mutation and therefore colon cancer.

2025-09-23 03:46:44 UTC

More males were killed compared to female, since males eat more processed meat per week than females in which contains a lot saturated fats, trans fats or cholesterol that lead to high blood cholesterol levels. Hence, leading to head in colon cancer.

s21m12 — 2025-09-23 03:48:13 UTC

According to table 2, there are 57.7% of male being served for more than 4 servings of processed meat per week, and there are 42.3% of female consumed more or 4 servings of processed meat per week. With the percentage of male higher than female, the mortality of male is higher than female for colon cancer, since more carcinogens enter into the colon to damage cells.

2025-09-23 04:17:33 UTC

The trend of mortality exhibited by all diseases increases with age.

2025-09-23 04:24:29 UTC

As heart diseases kills more male than females, and more males had a habit of of smoking, smoking contributes to heart disease by damaging blood vessels.

2025-09-23 04:29:12 UTC

According to table 1, males dying from colon cancer is more than the number of females.

And among those males, 57.7% had a lifestyle of actively consuming processed meat (~4 per week). This reflects that processed meat contributes to the death rates of colon cancer, as it contains many chemicals that could be cancer causing.
