Identifying low-PM exposure commuting routes for cyclists through modeling with the random forest algorithm based on low-cost sensor measurements in three Asian cities.

Cyclists can be easily exposed to traffic-related pollutants due to riding on or close to the road during commuting in cities. PM has been identified as one of the major pollutants emitted by vehicles and associated with cardiopulmonary and respiratory diseases. As routing has been suggested to reduce the exposures for cyclists, in this study, PM was monitored with low-cost sensors during commuting periods to develop models for identifying low exposure routes in three Asian cities: Taipei, Osaka, and Seoul.

Role of meteorological conditions in reported chickenpox cases in Wuhan and Hong Kong, China.

Background: Chickenpox is a common contagious disease that remains an important public health issue worldwide. Over 90% of unvaccinated individuals become infected, but infection occurs at different ages in different parts of the world. Many people have been infected by 20 to 30 years of age in China, and adults and pregnant women who become infected often develop severe infection.

Self-reported health problems related to traditional dietary practices in postpartum women from urban, suburban and rural areas of Hubei province, China: the 'zuò yuèzi'.

Background And Objectives: We aimed to investigate the prevalence of maternal health problems in the postpartum period and their association with traditional Chinese postpartum diets and behaviours in three selected regions in Hubei province, China.

Methods And Study Design: A cross-sectional study was conducted in urban, suburban and rural areas. A total of 2100 women who had given birth to full-term single infants in the past two years were enrolled.

Time series analysis of reported cases of hand, foot, and mouth disease from 2010 to 2013 in Wuhan, China.

Background: Hand, foot, and mouth disease (HFMD) is an infectious disease caused by a group of enteroviruses, including Coxsackievirus A16 (CVA16) and Enterovirus A71 (EV-A71). In recent decades, Asian countries have experienced frequent and widespread HFMD outbreaks, with deaths predominantly among children. In several Asian countries, epidemics usually peak in the late spring/early summer, with a second small peak in late autumn/early winter.

Vaccination coverage and its determinants among migrant children in Guangdong, China.

Background: Guangdong province attracted more than 31 million migrants in 2010. But few studies were performed to estimate the complete and age-appropriate immunization coverage and determine risk factors of migrant children.

Methods: 1610 migrant children aged 12-59 months from 70 villages were interviewed in Guangdong.

[Investigation on the risk factors for reported rising of measles incidence during November, 2011 to February, 2012, in some areas of Hubei province].

Objective: To identify the risk factors for reported sudden rise of measles incidence in November, 2011, in some areas of Hubei province.

Methods: We analyzed all measles patients reported in the measles surveillance system from November 2011 to February 2012 in two prefectures with highest attack rates and their vaccination history by reviewing vaccination records. We interviewed patients' parents by telephone to obtain the history of visiting health care within 7 to 21 days before onset.

Recurrence of Japanese encephalitis epidemic in Wuhan, China, 2009-2010.

Background: Japanese encephalitis (JE) was once epidemic in most areas of China, including Wuhan, a city located in the central part of China. The incidence of JE dramatically decreased due to nationwide immunization with the live attenuated JE virus (JEV) vaccine, and no JE cases were reported during 2005-2008 in Wuhan. In 2009 and 2010, 31 JE cases reoccurred in this area.

Implication of reported viral hepatitis incidence rate change in Hubei Province, China, between 2004-2010.

This study examined the change of reported incidence rate for viral hepatitis in Hubei province, China, between 2004 to 2010 to provide scientific evidence for viral hepatitis control. Reported viral hepatitis infection cases were queried from Centre for Disease Control of Hubei Province, China. The incidence of viral hepatitis A decreased steadily across the study period.

[Analysis of sequence and genotype of E gene of the newly isolated Japanese encephalitis virus strains in Wuhan, Hubei Province].

Objective: To analyze the molecular characteristics of the newly isolated two Japanese encephalitis virus strains (JEV) in Wuhan.

Methods: The mosquitoes were collected in Wuhan from April to October in 2009. The envelope (E) protein gene of JEV was detected using RT-PCR and sequenced.

[Early warning on measles through the neural networks].

To discuss the effects on early warning of measles, using the neural networks. Based on the available data through monthly and weekly reports on measles from January 1986 to August 2006 in Wuhan city. The modal was developed using the neural networks to predict and analyze the prevalence and incidence of measles.

The effect of health and nutrition education intervention on women's postpartum beliefs and practices: a randomized controlled trial.

Background: 'Sitting month' is the Chinese tradition for postpartum customs. Available studies indicate that some of the traditional postpartum practices are potentially harmful for women's health. However, no intervention study aiming at postpartum practices has been performed.

Postpartum practices of puerperal women and their influencing factors in three regions of Hubei, China.

Background: 'Sitting month' is a Chinese tradition for women's postpartum custom. The present study aims to explore the postpartum dietary and health practices of puerperal women and identify their influential factors in three selected regions of Hubei, China.

Methods: A cross-sectional retrospective study was conducted in the selected urban, suburban and rural areas in the province of Hubei from 1 March to 30 May 2003.
