The number of adults considered to be obese in Taiwan has reached a 10-year high, with experts attributing the increase to the prevalence of food-delivery services and the automated conveniences of modern living, a study released on Monday by the Health Promotion Administration found.
The percentage of people aged 18 or older considered obese or overweight increased to 43.9 percent in 2018 from 38 percent in 2009, the study showed.
The study defined obesity as having a body mass index of 24kg/m2 or greater.
In 2018, 17.2 percent of adults in Taiwan were overweight and 26.7 were obese, up from 13.6 percent overweight and 24.4 percent obese in 2009, the study showed.
Of the nation’s overweight and obese adults in 2018, the study showed that 55.1 percent were men and 32.5 percent were women, while 25 percent of those aged 18 to 24 and 35 percent of those aged 25 to 34 were overweight or obese.
The prevalence of being overweight or obese, which increases with age, is often connected with lifestyle changes, the Taiwan Medical Association for the Study of Obesity said on Monday.
For example, people entering the workforce tend to be overworked, meaning that they are less active and eat at irregular times, it said, adding that the problem is exacerbated by the slowing metabolism that accompanies aging.
“The increase in obesity — a serious problem — is mainly caused by eating more and being less active. These days you don’t even need to step outside to buy food,” association director-general Hsiao Tun-jen (蕭敦仁) said.
In the modern era, several automated conveniences have also contributed to weight gain, such as the prevalence of motor vehicles and washing machines, robot vacuum cleaners and office building elevators, he said, adding that increased stress and lack of proper sleep also contribute.
Obesity is especially a concern in winter, when colder temperatures increase the risk of heart problems, and also in the summer, when people tend to drink more sugary cold beverages to beat the heat — which results in a vicious cycle, he said.
The sour drinks sold at most beverage shops, such as citrus fruit or plum drinks, are especially harmful, as often a large amount of sugar is added to overcome the sourness, John Tung Foundation Department of Food and Nutrition director Hsu Hui-yu (許惠玉) said.
People should make their own fruit-flavored iced teas using fresh fruit, instead of buying drinks from beverage shops, Hsu said.
The military has spotted two Chinese warships operating in waters near Penghu County in the Taiwan Strait and sent its own naval and air forces to monitor the vessels, the Ministry of National Defense (MND) said. Beijing sends warships and warplanes into the waters and skies around Taiwan on an almost daily basis, drawing condemnation from Taipei. While the ministry offers daily updates on the locations of Chinese military aircraft, it only rarely gives details of where Chinese warships are operating, generally only when it detects aircraft carriers, as happened last week. A Chinese destroyer and a frigate entered waters to the southwest
The eastern extension of the Taipei MRT Red Line could begin operations as early as late June, the Taipei Department of Rapid Transit Systems said yesterday. Taipei Rapid Transit Corp said it is considering offering one month of free rides on the new section to mark its opening. Construction progress on the 1.4km extension, which is to run from the current terminal Xiangshan Station to a new eastern terminal, Guangci/Fengtian Temple Station, was 90.6 percent complete by the end of last month, the department said in a report to the Taipei City Council's Transportation Committee. While construction began in October 2016 with an
NON-RED SUPPLY: Boosting the nation’s drone industry is becoming increasingly urgent as China’s UAV dominance could become an issue in a crisis, an analyst said Taiwan’s drone exports to Europe grew 41.7-fold from 2024 to last year, with demand from Ukraine’s fight against Russian aggression the most likely driver of growth, a study showed. The Institute for Democracy, Society and Emerging Technology (DSET) in a statement on Wednesday said it found that many of Taiwan’s uncrewed aerial vehicle (UAV) sales were from Poland and the Czech Republic. These countries likely transferred the drones to Ukraine to aid it in its fight against the Russian invasion that started in 2022, it said. Despite the gains, Taiwan is not the dominant drone exporter to these markets, ranking second and fourth
Japanese Prime Minister Sanae Takaichi’s comment last year on Tokyo’s potential reaction to a Taiwan-China conflict has forced Beijing to rewrite its invasion plans, a retired Japanese general said. Takaichi told the Diet on Nov. 7 last year that a Chinese naval blockade or military attack on Taiwan could constitute a “survival-threatening situation” for Japan, potentially allowing Tokyo to exercise its right to collective self-defense. Former Japan Ground Self-Defense Force general Kiyofumi Ogawa said in a recent speech that the remark has been interpreted as meaning Japan could intervene in the early stages of a Taiwan Strait conflict, undermining China’s previous assumptions
