Association of Dietary Phytosterols Intake and Survival of Esophageal Squamous Cell Carcinoma: A Prospective Cohort Study.

Background: The association of dietary phytosterols intake with survival of esophageal squamous cell carcinoma (ESCC) remains unclear. This study was to examine the effect of dietary phytosterols intake on ESCC survival in a Chinese rural population.

Methods: A total of 942 incident ESCC patients diagnosed between 2011 and 2013 in Yanting area were followed up until March 1, 2020.

Dietary intake of monounsaturated and polyunsaturated fatty acids is related to the reduced risk of esophageal squamous cell carcinoma.

Background: The relationship of consumption of dietary fat and fatty acids with esophageal squamous cell carcinoma (ESCC) risk remains unclear. This study aimed to explore the relationship of dietary fat and fatty acids intake with ESCC risk.

Methods: This case-control study included 879 incident cases and 892 community-based controls recruited from Southwest China.

Household incense burning and children's respiratory health: A cohort study in Hong Kong.

Background: Incense burning is an important source of indoor air pollution in many Asian regions. We investigated the associations between household incense burning and lung function, lung function growth and respiratory diseases and symptoms in primary school children in Hong Kong.

Methods: A total of 4041 children (mean age: 9.

Digitalis use and lung cancer risk by histological type in men.

Lung cancer risk and tumor characteristics differ between sexes. Estrogen has been suggested to counteract lung cancer development. We aimed to test the hypothesis that digitalis use decreases lung cancer risk due to its estrogenic and other anticancer properties in men.

Frequent use of household cleaning products is associated with rhinitis in Chinese children.

Background: Despite the popular use of household cleaning products worldwide, there is no published study investigating the health effects of these products on rhinitis in children.

Objective: We sought to investigate the household use of cleaning products and rhinitis patterns in Chinese children.

Methods: A total of 2299 children were recruited from 21 primary schools with wide geographic coverage in Hong Kong.

Association of Circulating 25(OH)D and Lower Urinary Tract Symptoms: A Four-Year Prospective Study among Elderly Chinese Men.

The role of vitamin D in relation to lower urinary tract symptoms (LUTS) remains inconclusive. This four-year longitudinal study aims to explore the association of circulating 25(OH)D and LUTS in elderly Chinese men. Two thousand Chinese men aged 65 and older were recruited from a local community, of which 1998 (99.

The impact of breast cancer-specific birth cohort effects among younger and older Chinese populations.

Historically low breast cancer incidence rates among Asian women have risen worldwide; purportedly due to the adoption of a "Western" life style among younger generations (i.e., the more recent birth cohorts).

Time trends and age-period-cohort analyses on incidence rates of thyroid cancer in Shanghai and Hong Kong.

Background: Increasing incidence rates of thyroid cancer have been noted worldwide, while the underlying reasons remain unclear.

Methods: Using data from population-based cancer registries, we examined the time trends of thyroid cancer incidence in two largest cities in China, Shanghai and Hong Kong, during the periods 1973-2009 and 1983-2011, respectively. We further performed age-period-cohort analyses to address the possible underlying reasons for the observed temporal trends.

Sex difference in the incidence of nasopharyngeal carcinoma in Hong Kong 1983-2008: suggestion of a potential protective role of oestrogen.

Background: Nasopharyngeal carcinoma (NPC) shows a male predominance in incidence while the underlying reasons have rarely been explored.

Methods: We analysed incident cases of NPC recorded in Hong Kong Cancer Registry during the period 1983-2008. All cases were divided into 5-year age groups.

Residual beneficial effects after a 3-year integrated intervention on stroke in China: a 10-year prospective follow-up.

Objectives: To evaluate whether an intervention program designed to reduce stroke incidence would have long-term residual effects on reducing all-cause and cause-specific mortalities, including cancer 10 years after the intervention was completed.

Methods: This is a posttrial analysis. We prospectively observed the mortality of a community-based trial of primary prevention of stroke in China performed between July 1987 and June 1990 by extending the follow-up to 30 June 2000.

Time trends and age-period-cohort analyses on incidence rates of nasopharyngeal carcinoma during 1993-2007 in Wuhan, China.

Background: Declines in incidence rates of nasopharyngeal carcinoma (NPC) were observed in Hong Kong and Taiwan but not other high-risk regions in China, while evidences from low-risk regions in China are still lacking. This study aimed to examine the time trends (1993-2007) of NPC in Wuhan (a low-risk region) and assess the birth cohort and calendar period effects on the observed temporal trends.

Method: Using data from Wuhan Cancer Registry, age-standardized annual incidence rates of NPC were calculated by the direct method using the WHO World Standard Population (2000) as the reference.

Mortality in a Chinese chrysotile miner cohort.

Background: Few data were available to address cause-specific mortality in asbestos miners in China. This study observed a cohort of workers from the largest chrysotile asbestos mine to evaluate the association between asbestos exposure and cause-specific mortality.

Methods: The cohort consisting of 1,539 male workers was observed from 1981 to 2006.

Occupational health and safety challenges in China--focusing on township-village enterprises.

China has experienced dramatic industrialization, urbanization, and economic growth over the last 3 decades. The rapid transformation and dramatic prosperity of industries in rural areas have, in turn, created tremendous challenges for occupational health and safety (OHS). This article was prepared to address occupational health and safety issues in township- and village-owned enterprises (TVEs) from several aspects, including working conditions and workplace hazards, major recognized OHS problems, implications of TVE industries to environmental health, and migrant workers.

Previous pulmonary disease and family cancer history increase the risk of lung cancer among Hong Kong women.

Chinese women in Hong Kong have among the highest incidence and mortality of lung cancer in the world, in spite of a low prevalence of smoking. We carried out this population-based case-control study to evaluate the associations of previous lung disease and family cancer history with the occurrence of lung cancer among them. We selected 212 cases that were newly diagnosed with primary lung cancer, and randomly sampled 292 controls from the community, frequency matched by age group.

Cardiovascular risk factors in overweight and obese Chinese children: a comparison of weight-for-height index and BMI as the screening criterion.

Background: Childhood obesity is a widespread and growing problem in the world. Body mass index (BMI) and weight-for-height criterion have been used to determine childhood obesity. No data was available to evaluate cardiovascular risk factors in overweight and obese Chinese children screened by weight-for-height index and Chinese newly developed BMI criterion.

Time trends of esophageal cancer in Hong Kong: age, period and birth cohort analyses.

This study was to examine the time trend of the incidence rates of esophageal cancer during the period 1979-2003 in Hong Kong and to identify the effects of year of diagnosis (period) and year of birth (cohort) on the observed time trends using regression models. Cancer incidence data were obtained from Hong Kong Cancer Registry and population data were from the Census and Statistics Department. Age-standardized incidence rates were computed by the direct method using the World population of 1966.
