The impact of family factors and communication on recreational sedentary screen time among primary school-aged children: a cross-sectional study.

Background: Childhood obesity is increasingly recognized as a major public health challenge worldwide, and excessive sedentary screen time is emerging as a key risk factor. This study aimed to assess the recreational screen sedentary time of Chinese primary school-aged children and investigate the relationship between screen-related family factors and the outcome variable.

Methods: Our study used data from a cross-sectional survey collected from fifth-grade students and their parents in Beijing, China, from April to May 2018 (n = 2,373).

Effects of personal and interpersonal factors on changes of food choices and physical activity among college students.

Background: Health behaviors developed in the college years tend to persist in adulthood. However, distinct changing patterns of food choices and physical activity (PA) and their predictors are still less clear among college students. The current study sought to explore changes of food choices and PA, as well as the effects of personal and interpersonal factors.

Gender differences in social environmental changes associated with smoking: a cross-sectional study from Chinese internal migrants.

Objectives: To identify clues for women's tobacco control, this study analyses the gender differences in social environmental changes associated with smoking and the interaction between the environment and individuals' social integration.

Design, Setting And Participants: A cross-sectional design and secondary analysis were used among Chinese internal migrants. Data were from the 2012 Migrant Dynamics Monitoring Survey in China with participants aged 15-59 years old (75 416 women and 83 140 men) who resided in cities for more than 1 month.

[Study on radiation dose in different field of views of oral and maxillofacial cone-beam CT].

To analyze the absorptive radiation dose of non-target sensitive organs under the NewTomVGi oral and maxillofacial cone-beam CT scanning in different view fields. The thermoluminescence dosimeter chip was placed in the non-target sensitive organ of the simulated radiology head model, and 6 scanning fields were measured and analyzed (standard resolution: scanning range was 15 cm×15 cm, 15 cm×12 cm, 12 cm×8 cm, 8 cm×8 cm respectively). High definition resolution: the radiation absorption dose of thermoluminescence with the scanning range of 12 cm×8 cm, 8 cm×8 cm, respectively.

Three-dimensional human facial morphologies as robust aging markers.

Aging is associated with many complex diseases. Reliable prediction of the aging process is important for assessing the risks of aging-associated diseases. However, despite intense research, so far there is no reliable aging marker.

Simulation of Swanson's literature-based discovery: anandamide treatment inhibits growth of gastric cancer cells in vitro and in silico.

Swanson's literature-based discovery focus on resurrecting previously published but neglected knowledge. In this study, we propose a two-step model of the discovery process and generate a hypothesis between anandamide and gastric cancer. Further, the potential relationship was confirmed by follow-up experimentation.

Rapid quantification of highly polar trimethyl phosphate in wastewater via direct analysis in real-time mass spectrometry.

Trimethyl phosphate (TMP) is used extensively in industrial chemical processes. Due to the high polarity and volatility, methods for its quantification in environmental samples have not been well developed. Currently, the pollution status of TMP in the environment still has not been quantitatively analyzed.

Experience of offering HIV rapid testing to at-risk patients in community health centers in eight Chinese cities.

Objective: To explore the feasibility of offering HIV counseling and testing in community health centers (CHCs) and to provide evidence for the HIV/AIDS response in China.

Methods: Forty-two CHCs were selected from the eight cities that participated in the study. Rapid testing was mainly provided to: clients seeking HIV testing and counseling (HTC); outpatients with high-risk behavior of contracting HIV; inpatients and outpatients of key departments.

[Decomposition of life expectancy among permanent residents of Beijing, 2000 - 2010].

Objective: To analyze the change of life expectancy and the impact of mortality by age and causes of death on this issue among permanent residents of Beijing.

Methods: Abridged Life Table and Arriaga method were used to calculate and to decompose the changes on life expectancy by age and causes of death in 2000 - 2010.

Results: From 2000 - 2010, life expectancy under this studied population had an increase of 3.

[Characteristics of out-of-hospital acute coronary heart disease deaths of Beijing permanent residents at the age of 25 or more from 2007 to 2009].

Objective: To analyze the characteristics of out-of-hospital acute coronary heart disease (CHD) deaths in Beijing permanent residents at the age of 25 or more from 2007 to 2009.

Methods: We analyzed the gender, age, geographical distribution, occupation, marital status and the extent of different education characteristics of out-of-hospital acute CHD deaths of the Beijing permanent residents at the age of 25 or more from 2007 to 2009 using the mortality information database from the Beijing Vital Registration Monitoring System.

Results: Of the total 41 732 acute CHD deaths, 30 159 (72.

Safety and immunogenicity of adjuvanted inactivated split-virion and whole-virion influenza A (H5N1) vaccines in children: a phase I-II randomized trial.

Objective: Highly pathogenic avian influenza A virus H5N1 has the potential to cause a pandemic. Many prototype pandemic influenza A (H5N1) vaccines had been developed and well evaluated in adults in recent years. However, data in children are limited.

Immunogenicity, safety, and cross-reactivity of an inactivated, adjuvanted, prototype pandemic influenza (H5N1) vaccine: a phase II, double-blind, randomized trial.

Background: Avian influenza A virus H5N1 has the potential to cause a pandemic. Adjuvants and whole-virion vaccines are regarded as antigen sparing for pandemic vaccines.

Methods: A double-blind, randomized trial was performed from 28 August to 22 December 2007 in 402 adults; 301 adults were randomly assigned to receive 2 doses of an inactivated, aluminum-adjuvanted, whole-virion H5N1 vaccine containing 5, 10, or 15 microg of hemagglutinin per dose 28 days apart, and 101 of them received 2 doses of 10 microg of vaccine 14 days apart.
