Nutritional Status of Selenium and Its Association with Diet and Indoor Air Pollution among Pregnant Women in a Rural Area of Northern China
The nutritional status of selenium (Se) in pregnant women in rural areas of northern China and its association with diet and indoor air pollution are rarely reported. We recruited 273 pregnant women in early or middle term in Shanxi and Hebei province and detected their fasting blood selenium. Demographic characteristics, food habits, and indoor air pollution exposure were collected with a questionnaire. Multivariate logistic regression models we…
Folic acid supplementation and risk for congenital hydrocephalus in China
Objective: We examined whether folic acid (FA) supplementation prevented congenital hydrocephalus (CH) in more than 200 000 births in China. Design: A large population-based cohort study. Setting: All births at 20 complete gestational weeks, including live births, stillbirths and pregnancy terminations, and all structural birth defects regardless of gestational week were recorded. The prevalence of births with CH was classified by maternal charac…
Folate of pregnant women after a nationwide folic acid supplementation in China
Folate insufficiency during the periconceptional period increases the risk of neural tube defects (NTDs) in offspring, and folic acid supplementation substantially reduces the risk. Widespread large-scale folic acid supplementation (0.4-mg folic acid tablet) has been adopted as a main strategy to prevent NTDs in China since 2009. We examined folate concentrations in plasma and red blood cells (RBCs) of pregnant women and the factors associated wi…
Association between gestational weight gain and exclusive breast-feeding for the first 6 months postpartum in Chinese women
Objective The association between gestational weight gain (GWG) and exclusive breast-feeding (EBF) practices remains unclear. The present study evaluated the association between GWG and EBF in the first 6 months postpartum among primiparas in rural China. Design The study population was drawn from a previous randomized controlled trial, and the relevant data were obtained from an electronic, population-based perinatal system and a monitoring syst…
Changes in folic acid supplementation behaviour among women of reproductive age after the implementation of a massive supplementation programme in China
Objective To examine changes in periconceptional folic acid supplementation behaviour among Chinese women of reproductive age after the implementation of a folic acid supplementation programme. Design Two cross-sectional surveys were conducted. Setting One survey was before (2002–2004) and the other was after (2011–2012) implementation of the programme, both were conducted in two areas of China with different prevalence of neural tube defects. In…
Partner cigarette smoking and risk of neural tube defects among infants of non-smoking women in northern China
Peri-conceptional exposure to partner smoking may increase the risk of NTDs in the offspring of Chinese non-smoking women
Association of Education and the Occurrence of Low Birthweight in Rural Southern China During the Early and Late 1990s
Objectives. We examined whether education-related inequalities were associated with the occurrence of low birthweight in 6 counties in southern China in the early and late 1990s. Methods. The study population consisted of 111181 women (65669 in the early 1990s and 45482 in the late 1990s) in a population-based Perinatal Health Care Surveillance System. We used the χ 2 test, logistic regression, and concentration index for our analyses. Results. F…
Comparison of blood folate levels among pregnant Chinese women in areas with high and low prevalence of neural tube defects
Objective To characterise plasma and red-blood-cell (RBC) folate status among pregnant women in an area with an extremely high prevalence of neural tube defects, and to compare them with those of women from a low prevalence area. Design A cross-sectional survey conducted in 2003. Setting One county and one city from each of the high prevalence area and the low prevalence area in China. Subjects Five hundred and sixty-two women in their first trim…
Periconceptional use of folic acid in Shanxi Province of northern China
Objective To understand the periconceptional use of folic acid and its association with selected characteristics in northern China. Design As part of a population-based case–control study on external structural birth defects, we analysed periconceptional use of folic acid among control mothers. Setting The study was conducted in four counties (Pingding, Xiyang, Taigu and Zezhou) in Shanxi Province of northern China. Subjects The subjects in this …
Comprehensive periodic health examination: Impact on health care utilisation and costs in a working population in Japan
STUDY OBJECTIVE--To examine the impact of a comprehensive periodic health examination programme on health care utilisation and costs in a working population. DESIGN--A cohort method was used to observe the trends in health care utilisation and costs for a group of local government employees from 1 February 1986 until 31 January 1992, during which time (in 1988) a comprehensive periodic health examination programme had been introduced. Health care…
