The average weight of loaded school bags has fallen but some pupils still carry more than experts say is good for them, a survey has found. The average weight of bags weighed in Siu Sai Wan yesterday was 3.4kg, slightly higher than the recommended maximum of 3.2kg. Experts say the weight of a bag should not exceed 10 per cent of the child's weight. That recommendation is made by the Hong Kong Chiropractors' Association and the American Chiropractic Association. Nearly 43 per cent of the 79 bags weighed by the Democratic Alliance for Betterment of Hong Kong exceeded the limit, a drop of a quarter compared to last year. 'The problem is less severe than in the past,' said Eastern District Councillor and DAB member Chan Oi Kwan. 'People are more concerned about the weight of school bags.' Some schools have set up facilities such as lockers and water fountains so pupils can cut back on what they carry to school. Ms Chan suggested that students should use computers more and share books in class to reduce their burdens. Weighing just 28.5 kg, Primary Four student Michael Suen carried a 4.5 kg bag, well above the recommended maximum. He was carrying 14 books, stationery and a metal mooncake can for use in an art lesson. He said he was used to carrying a heavy bag. Marco Lau Wai-hang, also a Primary Four student, has started bringing two bags - a backpack and a hand-carry bag - to split the load. 'I feel a lot better now,' the nine-year-old said. 'Before, my school bag was so heavy that I felt tired climbing up and down the stairs.' Marco's mother agreed that his schoolbag had been too heavy and made him tired, and worried that his growth would be stunted. 'I'm afraid that his back bones and spine will suffer,' she said. In 2002, a nine-year-old boy fell 20 floors to his death in Tuen Mun when his school bag - loaded with books for the first day of term - apparently pulled him over safety railings.
