Smoking deprivation | Suicidal ideation in school students | Obesity surgery | Oestrogen in the environment

About 7% of Chinese people smoke so much their spending on cigarettes deprives the household of essential items like food, a study from Beijing has found. Low-income smokers were more likely to have smoking-induced deprivation.

Suicidal ideation occurs in one in three Chinese high school girls and 20% of boys, a study of 5249 students in Anhui Province of China has found.

Laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy are safe and effective for the treatment of morbid obesity, resulting in 63% and 76% loss of excess weight, a study from Nankai Hospital of Tianjin Medical University has shown.

The waist circumference cut off for high risk of central obesity and metabolic syndrome is 85 cm for women and 90 cm for men, researchers from Shandong have shown.

In Shanghai, almost one-in-five boys are obese and 8% of girls are obese. The prevalence of combined overweight and obesity is 49% for boys and 31% for girls aged 8-15-years, according to a study that found rates of obesity started to increase from age 10 years.

Oestrogen hormones are widely used in animal rearing in China and this leads to high levels of the hormones in excreted manure which is then used on crops, perpetuating the environmental contamination and human exposure, researchers from the State Key Laboratory of Water Environment Simulation, Beijing have shown.

The highly pathogenic strain of H7N9 avian influenza is quite different from other H7N9 strains seen in China and appears to have come about by re-assortment with the H9N2 strain, according to researchers from the Guangdong Provincial Center for Disease Control and Prevention.

Infliximab is safe and effective in Chinese patients with ulcerative colitis, resulting in 85% response rates and 62% remission rates after 30 weeks of treatment. However, relapse rates are high, say researchers from the Department of Gastroenterology, Nanfang Hospital, Southern Medical University, Guangzhou.
