News in brief: clinical studies from China

Measles is now rare in Guangzhou thanks to vaccination, but complete eradication will require vaccination of transient populations who now account for more than half of cases.

People who have a heart attack in China delay going to hospital for more than two hours, often because they don’t recognise the symptoms or their importance.

Chinese people consume dangerously high amounts of salt, with a Yantai study showing that 97% of men and 87% of women had intakes of over 6 g salt per day (mostly from added salt and soy sauce). Salt intake was related to high systolic blood pressure.

More than one in four new mothers in Guangzhou experience post-partum depression.

Compulsory routine infant vaccination with pneumococcal conjugate heptavalent vaccine would reduce pneumococcal disease in China by at least 32%, would prevent 2,682 deaths in the first five years of life and would save $1,190 million.

In rural China epilepsy goes untreated or undertreated in two out of three people with the condition, a Sichuan study has found. One third of people with epilepsy did not know about the disease and had not sought medical help.

The cultural pressure for gay men in China to marry means that their wives face a high risk of HIV and syphilis, researchers from Ningbo say. They found that only one in four gay men always used condoms with their wives, which explained HIV rates of more than 8% in women married to gay men.
