Data collected in a large epidemiologic study were analyzed to examine respiratory health effects of residential coal use in 7058 school children living in the four Chinese cities of Chongqing, Guangzhou, Lanzhou, and Wuhan. A Scenario Evaluation Approach was used to develop two exposure variables, heating coal smoke and cooking coal smoke. Estimated lifetime exposures to heating coal smoke and cooking coal smoke were both classified into four-level ordinal scales, as follows: no reported exposure (control); lightly exposed; moderately exposed; and heavily exposed. Zero-one dummy variables were constructed for each exposure level other than the control level (total six variables). These variables were entered into the analytical model. We tested for exposure-response relationships using logistic regression models, while controlling for other relevant covariates, including an indicator variable of ambient air pollution levels. We observed monotonic and positive exposure-response relationships of exposure to heating coal smoke with modeled odds ratios (ORs) of phlegm, cough with phlegm, and bronchitis. Other health outcomes were not associated with such exposure in a monotonic exposure-response pattern. However, ORs for cough, wheeze, and asthma were all higher in the exposed groups than in the control group. We observed no consistent associations between cooking coal smoke and the examined health outcomes. We conclude that exposure to heating coal smoke could have adverse effects on children's respiratory symptoms and illnesses in these four Chinese cities. 相似文献

《Vulnerable children and youth studies》2013,8(3):199-209
It is generally recognized that the acquired immune deficiency syndrome (AIDS) epidemic will have a negative effect on orphans' school education. However, few studies have been carried out to examine the school performance and school behaviour of AIDS orphans and vulnerable children [children living with human immunodeficiency virus (HIV)-infected parents]. Using both self-report and teacher evaluation data of 1625 children from rural central China, we examined the impact of parental HIV/AIDS on children's school performances (academic marks, educational expectation and student leadership) and school behaviours (e.g. aggression, shyness/anxiety and assertive social skills). Results indicate that AIDS orphans and vulnerable children had disadvantages in school performance in comparison to their peers from the same community who did not experience AIDS-related death and illness in their family (comparison children). AIDS orphans had the lowest academic marks based on the reports of both children and teachers. From a teacher's perspective, educational expectation was significantly lower among AIDS orphans and vulnerable children than comparison children. AIDS orphans were significantly more likely to demonstrate aggressive, impulsive and anxious behaviours than non-orphans. Moreover, orphans have more learning difficulties. Vulnerable children were also at a disadvantage on most measures. The data suggest that greater attention is needed to school performance and behaviour of children affected by AIDS. The findings also indicate that AIDS relief and assistance programmes for children should go beyond school attendance and efforts should be made to improve their school performance and educational aspirations. 相似文献

An epidemiological survey on serum lipids and apolipoproteins in school children in Goshiki-cho, Awaji-Island was carried out from 1985 to 1988 and their relations to blood pressure, anthropometric values, nutritional intake and a family history of hypertension were investigated. Parent-child and sibling-sibling correlations of the values were also analyzed. The results obtained were as follows: 1. During a 3-year follow-up from 11 to 14 years of age, serum levels of apo AI, apo AII, apo B and LDL cholesterol decreased at 12 years of age in both males and females. A tracking phenomenon was observed in serum levels of lipids and apolipoproteins. 2. Males at 10-14 years of age with a family history of hypertension (FH+) showed significantly higher systolic blood pressure and erythrocyte Na/K ratios than those without such a family history (FH-). The FH+ group (both males and females) had lower serum HDL cholesterol and higher levels of apo B, LDL cholesterol and triglyceride. 3. Significantly positive correlations were observed between apo AI levels of mother-son pairs and between those of elder and younger brother pairs. A positive correlation was observed between apo B levels of elder brother-younger sister pairs. Serum levels of total, HDL and LDL cholesterol in school children were closely correlated with the levels of the respective cholesterols in parents. Similar correlations were observed between sibling-sibling pairs. 相似文献

Background: Globally, solid fuels are used by about 3 billion people for cooking. These fuels have been associated with many health effects, including acute lower respiratory infection (ALRI) in young children. Nepal has a high prevalence of use of biomass for cooking and heating.Objective: This case–control study was conducted among a population in the Bhaktapur municipality, Nepal, to investigate the relationship of cookfuel type to ALRI in young children.Methods: Cases with ALRI and age-matched controls were enrolled from an open cohort of children 2–35 months old, under active monthly surveillance for ALRI. A questionnaire was used to obtain information on family characteristics, including household cooking and heating appliances and fuels. The main analysis was carried out using conditional logistic regression. Population-attributable fractions (PAF) for stove types were calculated.Results: A total of 917 children (452 cases and 465 controls) were recruited into the study. Relative to use of electricity for cooking, ALRI was increased in association with any use of biomass stoves [odds ratio (OR) = 1.93; 95% CI: 1.24, 2.98], kerosene stoves (OR = 1.87; 95% CI: 1.24, 2.83), and gas stoves (OR = 1.62; 95% CI: 1.05, 2.50). Use of wood, kerosene, or coal heating was also associated with ALRI (OR = 1.45; 95% CI: 0.97, 2.14), compared with no heating or electricity or gas heating. PAFs for ALRI were 18.0% (95% CI: 8.1, 26.9%) and 18.7% (95% CI: 8.4%–27.8%), for biomass and kerosene stoves, respectively.Conclusions: The study supports previous reports indicating that use of biomass as a household fuel is a risk factor for ALRI, and provides new evidence that use of kerosene for cooking may also be a risk factor for ALRI in young children. 相似文献

Factor analysis of household factors: are they associated with respiratory conditions in Chinese children? 总被引:2,自引:0,他引:2
BACKGROUND: We explored methods to develop uncorrelated variables for epidemiological analysis models. They were used to examine associations between respiratory health outcomes and multiple household risk factors. METHODS: We analysed data collected in the Four Chinese Cities Study (FCCS) to examine health effects on prevalence rates of respiratory symptoms and illnesses in 7058 school children living in the four Chinese cities: Lanzhou, Chongqing, Wuhan, and Guangzhou. We used factor analysis approaches to reduce the number of the children's lifestyle/household variables and to develop new uncorrelated 'factor' variables. We used unconditional logistic regression models to examine associations between the factor variables and the respiratory health outcomes, while controlling for other covariates. RESULTS: Five factor variables were derived from 21 original variables: heating coal smoke, cooking coal smoke, socioeconomic status, ventilation, and environmental tobacco smoke (ETS) and parental asthma. We found that higher exposure to heating coal smoke was associated with higher reporting of cough with phlegm, wheeze, and asthma. Cooking coal smoke was not associated with any of the outcomes. Lower socioeconomic status was associated with lower reporting of persistent cough and bronchitis. Higher household ventilation was associated with lower reporting of persistent cough, persistent phlegm, cough with phlegm, bronchitis, and wheeze. Higher exposure to ETS and the presence of parental asthma were associated with higher reporting of persistent cough, persistent phlegm, cough with phlegm, bronchitis, wheeze, and asthma. CONCLUSIONS: Our study suggests that independent respiratory effects of exposure to indoor air pollution, heating coal smoke, and ETS may exist for the studied children. 相似文献
