Cluster randomised controlled trial to assess a tailored intervention to reduce antibiotic prescribing in rural China: study protocol.

Introduction: Up to 80% of patients with respiratory tract infections (RTI) attending healthcare facilities in rural areas of China are prescribed antibiotics, many of which are unnecessary. Since 2009, China has implemented several policies to try to reduce inappropriate antibiotic use; however, antibiotic prescribing remains high in rural health facilities.

Methods And Analysis: A cluster randomised controlled trial will be carried out to estimate the effectiveness and cost effectiveness of a complex intervention in reducing antibiotic prescribing at township health centres in Anhui Province, China.

Meta-analysis of the mental health status of left-behind children in China.

The aims of this study were to systematically evaluate and comparatively analyse the mental health status of left-behind children (LBC) in China and to provide a scientific basis for mental intervention and healthy education for LBC.

Systematic review and meta-analysis found higher levels of behavioural problems in male left-behind children aged 6-11 years.

Aim: Left-behind children (LBC) now account for more than 1 in 5 Chinese children, and they often suffer from behavioural problems when their parents leave their rural homes to seek work in urban areas. The primary aim of this meta-analysis was to compare the incidence rates and factor scores of behavioural problems in LBC, who now account for more than one-fifth of Chinese children, and non-LBC.

Methods: This systematic review and meta-analysis explored the children's characteristic behavioural problems using the Achenbach Child Behaviour Check List.

Aim: Recently, increasing studies have been carried out to explore the association between vitamin D level and the development of diabetic peripheral neuropathy (DPN) in patients with diabetes mellitus (DM). However, because of the shortcoming in study design and sample size, there is still no clear conclusion. We performed this meta-analysis to examine the exact impact of vitamin D deficiency on DPN in type 2 diabetic patients.
