The National Health Research Institute sent an alarming message yesterday to the nation's betel-nut chewers: If they also smoke and drink, they are 195 times more likely to contract cancer of the esophagus than those who do not. They are also 96.9 times more likely to get cancer of the pharynx and 40.3 times more likely to contract cancer of the larynx.
Those statistics are based on a study conducted by a group of health researchers, headed by Ko Ying-chin (
Ko said at a presentation in Taipei yesterday that this shows chewing betel nuts has a detrimental effect on the overall metabolic system.
"Before, we only knew that chewing betel nuts could lead to oral cancer and other oral-related diseases," Ko said, "but now we have found that it can also harm other parts of the body."
Ko said that betel nuts have been identified by academics and researchers as a first-class cancer-causing substance. Even though betel-nut chewers spit out the juice, some of it is swallowed and goes into the bloodstream. Arecoline, an ingredient in the betel nut, becomes the residue that stays in the organs.
The study also studied the effect of betel nuts on pregnant women. It sampled 1,608 women from hospitals in southern and eastern Taiwan. The results showed that 14.72 percent of women who were habitual betel-nut chewers gave birth to underweight infants, versus 8.24 percent of those who were non-betel nut chewers.
On average, infants whose mothers chewed betel nuts during pregnancy weighed 3.0kg, while those whose mothers did not chew betel nuts weighed 3.1kg.
Pregnant women who chewed betel nuts were 2.8 times more likely to experience still births, miscarriages or have premature babies.
Yang Mei-sang (楊美賞), professor and dean of the college of nursing at Kaohsiung Medical College, said that a direct relationship has been established between a female's educational level and betel-nut chewing habit. Less educated females are more likely to become betel nut chewers, she said.
Yang also cited research results from other international medical journals to illustrate the potential effects of betel nuts. The study among Southeast Asian immigrants in Europe, for example, found that infants of betel-nut chewing mothers suffered from neonatal abstinence syndrome. It normally occurs among mothers taking addictive substance during pregnancy.
The institute's statistics also indicated that about 70,000 cancer cases are detected in the country each year, with 6 percent to 8 percent involving betel-nut chewers.
Oral cancer has been identified as one of the most common forms of cancer among males in the country, with a high incidence rate of 30 out of 100,000. Males who have oral cancer die, on average, at the age of 53 -- 10 years earlier than those who die from other forms of cancer.
The study also found that Aborigines account for a larger percentage of the betel-nut chewing population. Of the 10 percent of betel-nut chewers in Taiwan, 40 percent were Aborigines.
After India, Taiwan is the world's second-largest producer of betel nuts. Production increased from 3,718 tonnes in 1961 to 165,076 tonnes in 2001.
Ko estimated that the government has to spend at least NT$5 billion (US$151 million) a year to cover medical expenses for betel nut-related diseases.
Kenting National Park service technician Yang Jien-fon (楊政峰) won a silver award in World Grand Prix Photography Awards Spring Season for his photograph of two male rat snakes intertwined in combat. Yang’s colleagues at Kenting National Park said he is a master of nature photography who has been held back by his job in civil service. The awards accept entries in all four seasons across six categories: architectural and urban photography, black-and-white and fine art photography, commercial and fashion photography, documentary and people photography, nature and experimental photography, and mobile photography. Awards are ranked according to scores and divided into platinum, gold and
More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the
The Chinese Nationalist Party (KMT) caucus yesterday said it opposes the introduction of migrant workers from India until a mechanism is in place to prevent workers from absconding. Minister of Labor Hung Sun-han (洪申翰) on Thursday told the Legislative Yuan that the first group of migrant workers from India could be introduced as early as this year, as part of a government program. The caucus’ opposition to the policy is based on the assessment that “the risk is too high,” KMT caucus secretary-general Lin Pei-hsiang (林沛祥) said. Taiwan has a serious and long-standing problem of migrant workers absconding from their contracts, indicating that
SPACE VETERAN: Kjell N. Lindgren, who helps lead NASA’s human spaceflight missions, has been on two expeditions on the ISS and has spent 311 days in space Taiwan-born US astronaut Kjell N. Lindgren is to visit Taiwan to promote technological partnerships through one of the programs organized by the US for its 250th national anniversary. Lindgren would be in Taiwan from Tuesday to Saturday next week as part of the US Bureau of Educational and Cultural Affairs’ US Speaker Program, organized to celebrate the 250th anniversary of the signing of the Declaration of Independence, the American Institute in Taiwan (AIT) said in a statement yesterday. Lindgren plans to engage with key leaders across the nation “to advance cutting-edge technological partnerships and inspire the next generation of scientists and engineers,”
