Incidence and Related Factors for Hospital-Acquired Pneumonia Among Older Bedridden Patients in China: A Hospital-Based Multicenter Registry Data Based Study.

To identify the incidence and related factors for hospital-acquired pneumonia (HAP) among older bedridden patients in China. This multicenter registry data-based study conducted between November 2015 and March 2016 surveyed 7,324 older bedridden patients from 25 hospitals in China (six tertiary, 12 non-tertiary, and seven community hospitals). The occurrence of HAP among all participants was monitored by trained investigators.

Dietary folate, vitamin B6, vitamin B12 and methionine intake and the risk of breast cancer by oestrogen and progesterone receptor status.

Few studies have evaluated the relationship between the consumption of dietary folate and one-carbon metabolism-related nutrients and breast cancer risk defined by oestrogen receptor (ER) and progesterone receptor (PR) status. The objective of the present study was to examine the associations between dietary folate, vitamin B6, vitamin B12, and methionine intake and the risk of breast cancer by ER and PR status among Chinese women in Guangdong. A hospital-based case-control study was conducted from June 2007 to August 2008, with 438 cases and 438 age (5-year interval)- and residence (rural/urban)-matched controls.

Dietary fat intake and risk of breast cancer: a case-control study in China.

The association between consumption of fat and specific types of fat and the risk of breast cancer has been examined in previous studies, but the results remain unclear. Moreover, few studies were conducted in China, where dietary habits are different from those of the Western countries. We conducted a hospital-based case-control study from June 2007 to August 2008 among Chinese women residing in Guangdong to investigate the associations of dietary fat and specific types of fat with the risk of breast cancer.

Dairy products, calcium intake, and breast cancer risk: a case-control study in China.

The results of dairy food consumption and breast cancer risk are conflicting, and their relationship has not previously been studied in China. The objective of this study is to examine the association between dairy products, calcium intake, and breast cancer risk among Chinese women. A hospital-based case-control study was conducted among Chinese women in the Guangdong province from June 2007 to August 2008.

Dietary patterns and breast cancer risk among Chinese women.

Objective: The present study aimed to examine the relationship between dietary patterns and breast cancer risk among Chinese women.

Methods: Four hundred and thirty-eight cases with histologically confirmed primary breast cancer and 438 controls were consecutively recruited. Cases were frequency matched to controls on 5-year age group and rural-urban residence.

Meat and egg consumption and risk of breast cancer among Chinese women.

Objective: The association between meat and egg consumption and breast cancer risk has been examined in previous studies, but the results were inconsistent. We conducted a hospital-based case-control study during June 2007 to August 2008 among Guangdong Chinese women to investigate associations between meat and egg intake and breast cancer risk.

Methods: Four hundred and thirty-eight consecutively recruited cases with primary breast cancer were frequency matched to 438 controls by age (5-year interval) and residence (rural/urban).

Greater vegetable and fruit intake is associated with a lower risk of breast cancer among Chinese women.

The effect of vegetable and fruit consumption on breast cancer risk is controversial. We examined the association between vegetable and fruit intake and breast cancer risk in a hospital-based case-control study conducted in Guangdong, China. Four hundred and thirty-eight cases were frequency matched to 438 controls by age (5-year interval) and residence (rural/urban).
