Study: High BMI tied to hearing loss in women

The increasing risk associated with larger waist circumference followed a similar pattern.

New York: A high body mass and a large waist are both associated with self-reported hearing loss,a new study has found. Researchers used data from a 20-year prospective study of 68,421 women who were 25 to 42 years old at the start. They found that the higher the body mass index,the greater the risk for hearing loss. Compared with women with a BMI under 25,those with an index of 25 to 29 had an 8 per cent increased risk. The numbers kept going up in tandem: 11 per cent for 30 to 34,16 per cent for 35 to 39 and 19 per cent for those above 40. The increasing risk associated with larger waist circumference followed a similar pattern. The study,published in the December issue of The American Journal of Medicine,found that moderate physical activity — as little as four hours of walking a week — also reduced the risk for hearing loss.

Vitamin D,calcium no good for winter cough

New York: A randomised,placebo-controlled trial has found that vitamin D and calcium,whatever their other benefits may be,have no effect on upper respiratory tract infections. Researchers randomly placed 759 generally healthy people,aged 45 to 75 in four groups who received: a daily dose of 1,000 units of vitamin D,1,200 mg of calcium,vitamin D with calcium,or a placebo. During winters of the four-year study,those taking vitamin D had,on average,suffered 1.8 days of illness,compared with 1.6 days in the placebo group. And there were no significant differences between the groups in the duration of infection or severity of symptoms. Calcium supplementation did not help,either. It was not associated with the incidence,duration or severity of symptoms,and was equally ineffective.
