Leisure-time physical activity and risk of type 2 diabetes: a meta-analysis of prospective cohort studies.

Published articles reported controversial results about the association between leisure-time physical activity (LTPA) and risk of type 2 diabetes. A meta-analysis of prospective cohort studies was conducted to explore the effect of LTPA on the incidence of type 2 diabetes. PubMed and Embase databases were searched from its inception to June 13, 2014.

Sugar-sweetened beverages and risk of hypertension and CVD: a dose-response meta-analysis.

A number of prospective cohort studies have investigated the associations between consumption of sugar-sweetened beverages (SSB) and the risk of hypertension, CHD and stroke, but revealed mixed results. In the present study, we aimed to perform a dose-response meta-analysis of these prospective studies to clarify these associations. A systematic literature search was conducted using the PubMed and Embase databases up to 5 May 2014.

The proportion and trend of human immunodeficiency virus infections associated with men who have sex with men from Chinese voluntary blood donors: a systematic review and meta-analysis.

Background: Human immunodeficiency virus (HIV)-positive cases associated with men who have sex with men (MSM) have rapidly increased over the past years. The objective of this study is to comprehensively evaluate the proportions, changing trends, and geographical distribution of MSM-associated HIV cases from Chinese voluntary blood donors by systematically reviewing the available literature.

Study Design And Methods: Major English and Chinese research databases were searched for studies reporting study locations, study years, the number of HIV infections among blood donors, and the number of HIV-positive donations associated with MSM in China.

Nut consumption in relation to cardiovascular disease risk and type 2 diabetes: a systematic review and meta-analysis of prospective studies.

Background: Many prospective cohort studies have investigated the association between nut consumption and risk of coronary artery disease (CAD), stroke, hypertension, and type 2 diabetes (T2D). However, results have been inconsistent.

Objective: We aimed to investigate the association between nut consumption and risk of CAD, stroke, hypertension, and T2D.

HIV related high risk behaviors and willingness to participate in HIV vaccine trials among China MSM by computer assisted self-interviewing survey.

Background: The number of new HIV infections among MSM of China is rapidly increasing in recent years and behavioral interventions have had limited effectiveness. To control the HIV pandemic may lie in an HIV vaccine. This study examined the factors associated with willingness to participate (WTP) in HIV vaccine clinical trials among China MSM.

Physical activity and risk of hypertension: a meta-analysis of prospective cohort studies.

Published literature reports controversial results about the association of physical activity (PA) with risk of hypertension. A meta-analysis of prospective cohort studies was performed to investigate the effect of PA on hypertension risk. PubMed and Embase databases were searched to identify all related prospective cohort studies.

Sex-dependent associations of genetic variants identified by GWAS with indices of adiposity and obesity risk in a Chinese children population.

Objective: Recent genome-wide association studies have identified a few single nucleotide polymorphisms (SNPs), which are associated with body mass index (BMI)/obesity. This study aimed to examine the identified associations among a population of Chinese children.

Research Design And Methods: Five SNPs (SEC16B rs10913469, SH2B1 rs4788102, PCSK1rs6235, KCTD15 rs29941, BAT2 rs2844479) were genotyped for a group of Chinese children (N = 2849, age range 6-18 years).

Recapitulation of four hypertension susceptibility genes (CSK, CYP17A1, MTHFR, and FGF5) in East Asians.

Objective: A recent genome wide association study identified eight hypertension susceptibility loci in Europeans. Subsequently, several studies have investigated these associations in East Asian populations. The results of these studies, however, have been inconsistent.

Quantitative assessment of the associations between four polymorphisms (FokI, ApaI, BsmI, TaqI) of vitamin D receptor gene and risk of diabetes mellitus.

The vitamin D receptor (VDR) gene polymorphisms have been suggested to be involved in the development of diabetes mellitus, including type 1 diabetes (T1DM) and type 2 diabetes (T2DM). However, the results have been inconsistent. In this study, we performed a meta-analysis to investigate the associations.

Estimation and projection of the HIV epidemic trend among the migrant population in China.

Objective: The migrant population is a vulnerable group for HIV infection in China. Understanding potential epidemic trends among migrants is critical for developing HIV preventative measures in this population.

Methods: The Estimation and Projection Package (EPP) model was used to process prefecture and county-level surveillance data to generate HIV prevalence and epidemic trends for migrant populations in China.

Size, composition, and strength of ties of personal social support networks among adult people living with HIV/AIDS in Henan and Beijing, China.

To characterize the level of personal support available to people living with HIV/AIDS (PLWHA) in Henan and Beijing, China, face-to-face interviews were conducted to collect information on network size, composition, and strength of ties. The number of people as sources of support for participants in Henan varied from 1 to 13 and 1 to 16 in Beijing. In Henan, family members were more likely to provide support than non-relatives and they provided support more frequently; in Beijing non-relatives were more likely to provide support than family members.

Heterosexual risk of HIV infection in China: systematic review and meta-analysis.

Background: Heterosexual sex has become the dominant transmission route in China. Recently studies reported high heterogeneity in heterosexual transmission risk in resource-limited countries. The aim of this study was to summarize the risk of HIV transmission among Chinese serodiscordant couples.

A cross-sectional study of HIV and syphilis infections among male students who have sex with men (MSM) in northeast China: implications for implementing HIV screening and intervention programs.

Background: China has 76.2 million high school and college students, in which the number of reported HIV/AIDS cases is increasing rapidly. Most of these cases are attributed to male-to-male sexual contact.

Dynamic characteristic analysis of HIV mother to child transmission in China.

Objective: To explore dynamic characteristics of the HIV mother to child transmission (MTCT) epidemic in China.

Methods: A deterministic dynamic transmission model was used to determine the effect of key parameters on the likely long-term trends of the HIV MTCT epidemic in China. Matlab 7.
