Many women still deliver outside a health facility in Ghana, often under unhygienic conditions and without skilled birth attendants. This study aims to examine the social determinants influencing use of delivery among reproductive-aged Ghana.
Objective: The objective of this study was to assess respiratory outcomes and environmental exposure levels workers in cage-housed floor-housed poultry operations. Methods: Poultry operations were evaluated for total dust, endotoxin, ammonia, symptoms lung function tests conducted. Results: Workers had significantly greater exposures dust whereas from reported frequency current chronic overall phlegm (39% vs 18% 40% 11%, respectively). Endotoxin concentration (EU/mg) a significant predictor...
Abstract Background Inappropriate use of Caesarean Section (CS) delivery is partly to blame for Ghana’s high maternal mortality rate. However, previous research offered mixed findings about factors associated with CS use. The goal this study examine in Ghana and the socioeconomic it. Methods Data from nationally representative 2014 Demographic Health Survey (GDHS) was used after permission Monitoring Evaluation Assess Use Results (MEASURE) (DHS) program. Univariable multivariable logistic...
Airborne dust is an important contaminant affecting the health and environment, a crucial concern in many workplaces such as animal facilities potash mines. One of techniques used for control electrostatic particle ionization (EPI). This technology has been proven effective reducing airborne dust; however, it downsides, generation ozone corrosion electrodes. Thus, this study tested corrosion-resistant carbon-fiber discharge electrode compared with electrodes commonly EPI systems, that is,...
The relationship between household endotoxin and asthma in children is not clear. To further investigate the sources of childhood asthma, we conducted a case-control study with without examined their more frequent exposures home. Children ages 6-13 years current (n = 70) or wheeze only 19) were sex age matched (+/-1 year) to 107 controls. Play area mattress dust collected for analysis. Atopic status was determined by skin prick testing allergies. A family size >4 per associated higher levels...
Current knowledge regarding the association between indoor mold exposures and asthma is still limited. The objective of this case-control study was to investigate relationship objectively measured levels current among school-aged children. Parents completed a questionnaire survey health history home environmental conditions. Asthma cases had doctor-diagnosed or wheeze without cold in past 12 months. Controls were age- sex-matched cases. Vacuumed dust samples collected from child's play area...
A crossover trial was conducted to evaluate the acute human health effects of a dust control technology in swine confinement facility. Twenty lifetime nonsmoking male subjects, with no evidence allergy or asthma and previous barn exposure, participated study, which included laboratory session (baseline), 5-h exposure room sprinkled canola oil (treatment) traditional (control). Mean values inhalable concentrations endotoxin levels were significantly greater than those observed treatment room....
Background: Individuals engaged in work intensive animal houses experience some of the highest rates occupationally related respiratory symptoms. Organic dust and particular endotoxin has been most closely associated with symptoms lung function changes workers. It previously shown that for poultry operations, type housing [cage-housed (CH) versus floor-housed (FH)] can influence levels environmental contaminants. The goal study was to determine differences at different size fractions between...
Respiratory disease can impose a significant burden on the health of rural populations. The Saskatchewan Rural Health Study (SRHS) is new large prospective cohort study ages 6 and over currently being conducted in farming non-farming communities to evaluate potential determinants associated with respiratory outcomes In this article, we describe rationale methodology for adult component. 5 years (2009–15) two phases, baseline longitudinal. survey consists components, adults children....
Background:Antibiotics are used in animal confinement buildings, such as cage-housed (CH) and floor-housed (FH) poultry operations, to lower the likeliness of disease transmission. In FH facilities, antibiotics may also be at sub-therapeutic levels for growth promotion. Low antibiotic create a selective pressure toward antimicrobial resistance (AMR) chicken fecal bacteria.
To date, determinants of respiratory health in First Nations people living on reserves and means addressing redressing those have not been well established. Hence the Saskatchewan Lung Health Project (FNLHP) is a new prospective cohort study aboriginal being conducted two to evaluate potential associated with outcomes. Using population framework (PHF) Canada, instruments designed communities, joint ownership data, based 4-phase concept Regional Longitudinal Survey, project aims individual...
To determine predictors of longitudinal changes in pulmonary function swine confinement workers.Longitudinal study conducted from November 1989 to June 1991 and January 1994 May 1995.Swine workers Saskatchewan.Forty-two who were studied 1989/90 again 1994/95.Of 98 male (mean age SD 36.3 11.1 years) at baseline, 42 five years following. Complete information on baseline across-shift (preshift forced expiratory volume 1 s [FEV1], vital capacity [FVC], every 2 h FEV1 FVC during the shift),...
OBJECTIVE: To determine whether poultry production methods impact respiratory health, and farmers have more symptoms lower lung function than comparison control groups. DESIGN: Cross‐sectional study. SETTING: Provinces of Saskatchewan, Alberta Manitoba during the winters 1997 to 1999. POPULATION: Three hundred three workers, 241 grain 206 nonfarming subjects were studied. Poultry workers further classified according housing type in which they worked, ie, who worked with raised on floor...
Abstract Background It has been shown that exposure in intense swine barn facilities is associated with increased respiratory symptoms and reduction pulmonary functions. This study investigated if systemic response could be predicted by FEV 1 following exposure. Methods Naïve males were tested at baseline, low high endotoxin dust levels. Subjects classified as “more responsive” (n = 9) or “less 11) based on Health measures included function testing, blood samples nasal lavage. Environmental...
Although bioaerosols from both cage-housed (CH) and floor-housed (FH) poultry operations are highly concentrated, the concentrations of dust, endotoxin, bacteria significantly higher in FH bioaerosols. Workers CH have reported a greater prevalence respiratory symptoms. To date, archaea been examined swine dairy but not The objective this study was to directly compare methanogenic facilities. Bioaerosols were collected 15 operations, using stationary area samplers as well personal sampling...
