Investigation on the trace elemental profile of sewage workers in Kolkata, an Indian megacity
Get PDFBackground. Environmental pollution has become a global health risk. Exposure to pollutants at the work place, i.e. occupational exposure, is one of the areas that need immediate attention. The civic drainage workers are exposed to pollutants present in the wastewater they handle and most of them are toxic heavy metals. Exposure to such pollutants may be a health hazard, since it can lead to the imbalance in nutrient elements status.§Design and Methods. In the present study, profiling of trace elements in the blood of drainage worker population from an Indian megacity, Kolkata, was carried out by energy dispersive x-ray fluorescence (EDXRF) and compared with the control group population of the same area. Results. The elements detected by EDXRF spectrometry include P, S, Cl, K, Fe, Cu, Zn, Se, Br, and Rb. By using ANOVA with 5% significance level, we observed significant alterations in the trace elements status, iron over loading, selenium deficiency, and in Cu-Zn ratio. Gender specific variations within the same population were also observed. Conclusions. The results indicate that the drainage workers have altered elemental profile in comparison to that of control population
H1N1 influenza pandemic in Italy revisited: has the willingness to get vaccinated suffered in the long run?
Get PDFBackground. The aim of the study is to assess the long-term secondary effects of personal experience with the H1N1 pandemic of 2009/2010 and the perception of the institutional reaction to it on Italians’ willingness to get vaccinated in case of a novel influenza pandemic. Design and Methods. We conducted 140 face-to-face interviews in the Registry Office of the Municipality of Milan, Italy, from October to December 2012. Results. Willingness to get vaccinated during a novel influenza pandemic was best predicted by having been vaccinated against the seasonal flu in the past (OR=5.18; 95%CI: 1.40 to 19.13) and fear of losing one’s life in case of an infection with H1N1 (OR=4.09; 95%CI: 1.68 to 9.97). It was unaffected by the assessment of institutional performance. Conclusions. The findings of this study do not point to long-term secondary effects of the institutional handling of the H1N1 pandemic. The results highlight the fact that behavioural intention is not the same as behaviour, and that the former cannot simply be taken as an indicator of the latter
Vitamin D status, bone mineral density and mental health in young Australian women: the Safe-D study
Get PDFBackground. Vitamin D deficiency has been associated with both poor bone health and mental ill-health. More recently, a number of studies have found individuals with depressive symptoms tend to have reduced bone mineral density. To explore the interrelationships between vitamin D status, bone mineral density and mental-ill health we are assessing a range of clinical, behavioural and lifestyle factors in young women (Part A of the Safe-D study). Design and methods. Part A of the Safe-D study is a cross-sectional study aiming to recruit 468 young females aged 16-25 years living in Victoria, Australia, through Facebook advertising. Participants are required to complete an extensive, online questionnaire, wear an ultra-violet dosimeter for 14 consecutive days and attend a study site visit. Outcome measures include areal bone mineral measures at the lumbar spine, total hip and whole body, as well as soft tissue composition using dual energy x-ray absorptiometry. Trabecular and cortical volumetric bone density at the tibia is measured using peripheral quantitative computed tomography. Other tests include serum 25-hydroxyvitamin D, serum biochemistry and a range of health markers. Details of mood disorder/s and depressive and anxiety symptoms are obtained by self-report. Cutaneous melanin density is measured by spectrophotometry. Expected impact. The findings of this cross-sectional study will have implications for health promotion in young women and for clinical care of those with vitamin D deficiency and/or mental ill-health. Optimising both vitamin D status and mental health may protect against poor bone health and fractures in later life
Neurodevelopmental outcome of high risk newborns discharged from special care baby units in a rural district in India
Get PDFBackground. High risk newborns are most vulnerable to develop neuro-developmental delay (NDD). Early detection of delay in this group and identification of associated perinatal factors and their prevention can prevent disability in later life. Design and methods. Observational cohort study. Field based tracking and neuro-developmental screening of high risk newborns discharged between January 2010 to June 2012 from a district Hospital in India was conducted by a team of developmental specialists, using standardized tools like Denver Developmental Screening Tool II, Trivandrum Developmental Screening Chart and Amiel-Tison method of tone assessment. Associated perinatal factors were identified. Early intervention was initiated on those detected with NDD. Results. Developmental delay was detected in 31.6% of study population. Prevalence of NDD was significantly higher in low birth weight (LBW, >2 kg), preterm (<36 weeks) and twins. Neonatal sepsis/meningitis and convulsions also showed significant association with NDD. Of the 134 with developmental delay, 61 were preterm, 80 LBW, with h/o sepsis in 52, convulsion in 14, birth asphyxia in 39 and jaundice in 14 neonates. Conclusions. Incidence of NDD among high risk newborns is significantly high with LBW, prematurity and neonatal illnesses are major contributors. Most NDDs go undetected in the early years of life. Improved perinatal care, early detection and early intervention at the grass root level will bring down incidence of developmental challenges in this vulnerable group
Childhood malnutrition is associated with maternal care during pregnancy and childbirth: a cross-sectional study in Bauchi and Cross River States, Nigeria
Get PDFBackground. Malnutrition remains an important cause of childhood morbidity and mortality; the levels of childhood malnutrition in Nigeria are among the highest in the world. The literature supports many direct and indirect causes of malnutrition, but few studies have examined the link between maternal care during pregnancy and childbirth and childhood malnutrition. This study examines this potential link in Bauchi and Cross River states in Nigeria. Design and methods. In 2011, a household survey collected information about children under four years old and their mothers’ last pregnancy. Trained fieldworkers measured mid-upper arm circumference (MUAC) of children aged 6-47 months. We examined associations with childhood malnutrition in bivariate and multivariate analysis. Results. Some 4.4% of 3643 children in Cross River, and 14.7% of 2706 in Bauchi were malnourished (MUAC z-score). In both states, a child whose mother had fewer than four government antenatal care visits was more likely to be malnourished (Cross River: OR 1.85, 95%CIca 1.33-2.55; Bauchi: OR 1.29, 95%CIca 1.02-1.63). In Bauchi, a child whose mother who rarely or never discussed pregnancy and childbirth with her husband (OR 1.34, 95%CIca 1.07-1.68), and who did not have her last delivery attended by a skilled health worker was more likely to be malnourished (OR 1.50, 95%CIca 1.09-2.07). Conclusions. These findings, if confirmed in other studies, suggest that poor care of women in pregnancy and childbirth could pose a longer term risk to the health of the child, as well as increasing immediate risks for both mother and child
From disappointment to holistic ideals: a qualitative study on motives and experiences of using complementary and alternative medicine in Sweden
Get PDFBackground. Recent studies indicate increased use of complementary and alternative medicine (CAM) in western societies, to ameliorate health problems. Even if there is substantial research on general patterns of use, there is limited knowledge on individual motives. This study contributes to a qualitative understanding of experiences of choosing and using CAM. Design and methods. This study consists of in-depth interviews with 10 CAM users in Sweden. The participants represent different backgrounds and experiences of using CAM. The interviews have been analysed in accordance with content analysis. Results. In analysing experiences of choosing and using CAM four main themes were identified: frustration and critique, values and ideology, individual responsibility, and combining treatments. In general, the participants were highly reflexive on issues concerning their health. They highlighted their own role and responsibility, combined a variety of treatments, and continuously dealt with questions on risks, even if they had relatively different approaches to if and when to use CAM. The results also show that motives may change over time. Even if initial choices were closely related to frustration and critique of conventional treatments (for example, by perceiving conventional health care as limited, not receiving proper diagnoses, or being critical to conventional drugs) was long-term use motivated by ideological characteristics of CAM (such as holistic and individualized treatments, and extensive interaction with practitioners).Conclusions. Four main themes, concerning experiences of choosing and using CAM were identified. This study also supports the idea that initial motives for choosing CAM may differ from those explaining long-term use
Influence of indoor hygrothermal conditions on human quality of life in social housing
Get PDFBackground: Modern societies spend most of their time indoors, namely at home, and the indoor environment quality turns out to be a crucial factor to health, quality of life and well-being of the residents. The present study aims to understand how indoor environment relates with quality of life and how improving housing conditions impacts on individuals’ health. Design and Methods: This study case will rely on the following assessments in both rehabilitated and non-rehabilitated social housing: i) field measurements, in social dwellings (namely temperature, relative humidity, carbon dioxide concentration, air velocity, air change rate, level of mould spores and energy consumption); ii) residents’ questionnaires on social, demogaphic, behavioural, health characteristics and quality of life. Also, iii) qualitative interviews performed with social housing residents from the rehabilitated houses, addressing the self-perception of living conditions and their influence in health status and quality of life. All the collected information will be combined and analysed in order to achieve the main objective. Expected impact: It is expected to define a Predicted Human Life Quality (PHLQ) index, that combines physical parameters describing the indoor environment measured through engineering techniques with residents’ and neighbourhood quality of life characteristics assessed by health questionnaires. Improvement in social housing should be related with better health indicators and the new index might be an important tool contributing to enhance quality of life of the residents
Dental caries and the associated factors influencing it in tribal, suburban and urban school children of Tamil Nadu, India: a cross sectional study
Get PDFBackground. The study was planned to assess the prevalence of dental caries among tribal, suburban and urban children of Tiruchengode and Erode of Tamil Nadu state, India. The objective of the study was to assess the association of dental caries with family background, dental service availability, transportation and knowledge on preventive dental measures among these three groups. Design and methods. Cross-sectional study. A total of 1028 school children in the age range of 9-12 years from various government schools located in Palamalai and Kolli Hills (tribal), Tiruchengode (suburban) and Erode (urban), Tamil Nadu, were included in the study. Decayed, filled, and missing teeth (DMFT), decayed and filled teeth (dft) and Significant Caries Index were recorded. A specially prepared questionnaire was used to record all the data regarding oral hygiene practices, socioeconomic background, dental treatment availability, parent’s education level were used for the study. ANOVA t-test and post hoc test were used for comparing quantitative variables between the 3 subgroups. Results. The tribal school children had 89.3% caries prevalence, where as it was 77% in suburban and 55% in urban school children. The mean DMFT score among tribal, suburban and urban school children were statistically significant different (P=0.001) between the three groups. There was a highly significant difference (P=0.001) in the mean DMFT score based on brushing frequency. There was a statistically significant difference (P=0.018) in the mean DMFT scores in the urban group based on the mothers education status. There were no statistically significant differences in the mean DMFT scores based on the presence or absence of television in their house and the parents’ income. Conclusions. Oral hygiene practices, dietary habits and access to dental care services played an important role in prevalence of dental caries. It was observed that the socioeconomic status, parents’ educational status and mass media influenced the oral health of these children but without a significant contribution
Community Priority Index: utility, applicability and validation for priority setting in community-based participatory research
Get PDFBackground. Providing practitioners with an intuitive measure for priority setting that can be combined with diverse data collection methods is a necessary step to foster accountability of the decision-making process in community settings. Yet, there is a lack of easy-to-use, but methodologically robust measures, that can be feasibly implemented for reliable decision-making in community settings. To address this important gap in community based participatory research (CBPR), the purpose of this study was to demonstrate the utility, applicability, and validation of a community priority index in a community-based participatory research setting. Design and Methods. Mixed-method study that combined focus groups findings, nominal group technique with six key informants, and the generation of a Community Priority Index (CPI) that integrated community importance, changeability, and target populations. Bootstrapping and simulation were performed for validation. Results. For pregnant mothers, the top three highly important and highly changeable priorities were: stress (CPI=0.85; 95%CI: 0.70, 1.00), lack of affection (CPI=0.87; 95%CI: 0.69, 1.00), and nutritional issues (CPI=0.78; 95%CI: 0.48, 1.00). For non-pregnant women, top priorities were: low health literacy (CPI=0.87; 95%CI: 0.69, 1.00), low educational attainment (CPI=0.78; 95%CI: 0.48, 1.00), and lack of self-esteem (CPI=0.72; 95%CI: 0.44, 1.00). For children and adolescents, the top three priorities were: obesity (CPI=0.88; 95%CI: 0.69, 1.00), low self-esteem (CPI=0.81; 95%CI: 0.69, 0.94), and negative attitudes toward education (CPI=0.75; 95%CI: 0.50, 0.94). Conclusions. This study demonstrates the applicability of the CPI as a simple and intuitive measure for priority setting in CBPR
A stakeholder-based system dynamics model of return-to-work: a research protocol
Get PDFBackground. Returning to work following a job-related injury or illness can be a complex process, influenced by a range of interrelated personal, psychosocial, and organizational components. System dynamics modelling (SDM) takes a sociotechnical systems perspective to view return-to-work (RTW) as a system made up of multiple feedback relationships between influential components. Design and Methods. To build the RTW SDM, a mixed-method approach will be used. The first stage, that has already been completed, involved creating a baseline model using key informant interviews. Second, in two manufacturing companies, stakeholder-based models will be developed through interviews and focus groups with senior management, frontline workers, and frontline supervisors. Participants will be asked about the RTW process in general and more targeted questions regarding influential components. Participants will also be led through a reference mode exercise where they will be asked to estimate the direction, shape and magnitude of relationships between influential components. Data will be entered into the software program Vensim that provides a platform for visualizing system-structure and simulating the effects of adapting components. Finally, preliminary model validity testing will be conducted to provide insights on model generalizability and sensitivity. Expected Impact of the study for Public Health. The proposed methodology will create a SDM of the RTW process using feedback relationships of influential components. It will also provide an important simulation tool to understand system behaviour that underlies complex RTW cases, and examine anticipated and unanticipated consequences of disability management policies
