Prevalence of unmet health care need in older adults in 83 countries: measuring progressing towards universal health coverage in the context of global population ageing.

Current measures for monitoring progress towards universal health coverage (UHC) do not adequately account for populations that do not have the same level of access to quality care services and/or financial protection to cover health expenses for when care is accessed. This gap in accounting for unmet health care needs may contribute to underutilization of needed services or widening inequalities. Asking people whether or not their needs for health care have been met, as part of a household survey, is a pragmatic way of capturing this information. This analysis examined responses to self-reported questions about unmet need asked as part of 17 health, social and economic surveys conducted between 2001 and 2019, representing 83 low-, middle- and high-income countries. Noting the large variation in questions and response categories, the results point to low levels (less than 2%) of unmet need reported in adults aged 60+ years in countries like Andorra, Qatar, Republic of Korea, Slovenia, Thailand and Viet Nam to rates of over 50% in Georgia, Haiti, Morocco, Rwanda, and Zimbabwe. While unique, these estimates are likely underestimates, and do not begin to address issues of poor quality of care as a barrier or contributing to unmet need in those who were able to access care. Monitoring progress towards UHC will need to incorporate estimates of unmet need if we are to reach universality and reduce health inequalities in older populations.

Time of onset and/or diagnosis of ADHD in European children: a systematic review.

BACKGROUND: Attention-Deficit/ Hyperactivity Disorder (ADHD) is one of the most common childhood neurobehavioral conditions. Symptoms related to this disorder cause a significant impairment in school tasks and in the activities of children's daily lives; an early diagnosis and appropriate treatment could almost certainly help improve their outcomes. The current study, part of the Models Of Child Health Appraised (MOCHA) project, aims to explore the age at which children experience the onset or diagnosis of ADHD in European countries. METHODS: A systematic review was done examining the studies reporting the age of onset/diagnosis (AO/AD) of ADHD in European countries (28 European Member States plus 2 European Economic Area countries), published between January 1, 2010 and December 31, 2019. Of the 2276 identified studies, 44 met all the predefined criteria and were included in the review. RESULTS: The lowest mean AO in the children diagnosed with ADHD alone was 2.25 years and the highest was 7.5 years. It was 15.3 years in the children with ADHD and disruptive behaviour disorder. The mean AD ranges between 6.2 and 18.1 years. CONCLUSIONS: Our findings indicate that there is a wide variability in both the AO and AD of ADHD, and a too large distance between AO and AD. Since studies in the literature suggest that an early identification of ADHD symptoms may facilitate early referral and treatment, it would be important to understand the underlying reasons behind the wide variability found.

Quality of child healthcare in European countries: common measures across international databases and national agencies.

BACKGROUND: The evaluation of child healthcare is not yet widely explored, especially from a cross-country comparison perspective. The routine adoption of measures by national assessment agencies is under-investigated. Though the guiding principles developed at international level call for a child-centric multi-dimensional evaluation of child care, its feasibility is hampered by the availability of robust and harmonized data. METHODS: To explore the data availability, international databases (IDBs) were scrutinized and measures dealing with child health-related issues were collated. In parallel, an ad hoc questionnaire was administrated to 30 Country Agents (CAs) to gather measures routinely adopted at local level. To facilitate the comparison of measures, a three-level conceptual map was developed. RESULTS: The IDBs yielded at 207 measures that pertained mainly to non-health determinants of health, whereas the 352 measures obtained from CAs focused on process and outcome. A set of 33 common measures that related to immunization, morbidity and mortality were identified. CONCLUSIONS: A limited set of measures used both in IDBs and at national level identify common areas of concerns that certainly capture crucial issues with child prevention and health outcomes. However, they are far from satisfying a child-centric multi-dimensional approach to the evaluation of child well-being and well-becoming. There is room for improvement at both international and national levels. IDBs should include and harmonize measures that concern the provision of child-centric services and encompass physical, social and mental development. At the national level, efforts towards the inclusion of measures that concern non-health determinants of health should be pursued.

Variability in the assessment of children's primary healthcare in 30 European countries.

BACKGROUND: The high variability in the types and number of measures adopted to evaluate childcare across European countries makes it necessary to investigate country practices to identify trends in setting national priorities in the assessment of child well-being. OBJECTIVE: This paper intends to investigate country practices under the lens of variability to explore possible trends in setting national priority in the evaluation of childcare. In particular, it analyses variability considering to what extent this depends on the tendency of adopting a broad vision (i.e. selecting measures for a larger variety of aspects) or whether this is influenced by the choice of adopting an in-depth approach (i.e. using more measures to analyse a specific aspect). METHODS: An ad hoc questionnaire was administered to a national expert in each country and yielded 352 measures. To analyse variability, the breadth in the number of aspects considered was explored using a convergence index, while the depth in the distribution of measures in each aspect was investigated by computing a coefficient of variation. Countries were grouped by adopting a hierarchical clustering approach. RESULTS: There is a high variability across countries in the selection of measures that cover different aspects of childcare. Preferences in the distribution of measures are significant even at the domain level and in countries that use a limited number of measures and become more evident at the category and sub-category levels. The statistical analysis clusters countries in four main groups and two outliers. The in-depth distribution of measures focused on a specific aspect shows a homogeneous pattern, with the identification of two main groups of countries. CONCLUSIONS: A limited set of measures are shared across countries hampering a robust comparison of paediatric models. The selection of measures shows that the evaluation is closely related to national priorities as resulting from the number and types of measures adopted. Moreover, a range of a reasonable number of measures can be hypothesized to address the quality of childcare under a multi-dimensional perspective.

Quality of life improvement in children with attention-deficit hyperactivity disorder reduces family's strain: A structural equation model approach.

OBJECTIVES: The objective of the study is to analyse how the quality of life of children diagnosed with attention-deficit/hyperactivity disorder (ADHD) impacts the relationship between disease severity and family burden. METHOD: The data collected by a longitudinal, observational study involving 1478 children with ADHD residing in 10 European countries (aged 6 to 18 years) were analysed to evaluate the relationships between ADHD severity, the children's quality of life and family burden. RESULTS: The disorder's severity directly and indirectly affected the children's health-related quality of life (HRQoL) and family burden. The degree of family burden was modulated by the children's HRQoL. CONCLUSIONS: One of the primary causes of the stress experienced by parents of children with ADHD is their perception of the child's reduced HRQoL and not the symptom severity itself. Efforts to minimize symptom severity cannot alone reduce family burden.

Evaluation of the Association Between Health State Utilities and Obesity in Sub-Saharan Africa: Evidence From World Health Organization Study on Global AGEing and Adult Health Wave 2.

BACKGROUND: Obesity is a major public health challenge and its prevalence has increased across the age spectrum from 1980 to date in most parts of the world including sub-Saharan Africa. Studies that derive health state utilities (HSUs) stratified by weight status to support the conduct of economic evaluations and prioritization of cost-effective weight management interventions are lacking in sub-Saharan Africa. OBJECTIVES: To estimate age- and sex-specific HSUs for Ghana, along with HSUs by weight status. Associations between HSUs and overweight and obesity will be examined. STUDY DESIGN: Cross-sectional survey of the Ghanaian population. METHODS: Data were sourced from the World Health Organization Study of Global AGEing and Adult Health (WHO SAGE), 2014 to 2015. Using a "judgment-based mapping" method, responses to items from the World Health Organization Quality-of-Life (WHOQOL-100) used in the WHO SAGE were mapped to EQ-5D-5L profiles, and the Zimbabwe value set was applied to calculate HSUs. Poststratified sampling weights were applied to estimate mean HSUs, and a multivariable linear regression model was used to examine associations between HSUs and overweight or obesity. RESULTS: Responses from 3966 adults aged 18 to 110 years were analyzed. The mean (95% confidence interval) HSU was 0.856 (95% CI: 0.850, 0.863) for the population, 0.866 (95% CI: 0.857, 0.875) for men, and 0.849 (95% CI: 0.841, 0.856) for women. Lower mean HSUs were observed for obese individuals and with older ages. Multivariable regression analysis showed that HSUs were negatively associated with obesity (-0.024; 95% CI: -0.037, -0.011), female sex (-0.011; 95% CI: -0.020, -0.003), and older age groups in the population. CONCLUSIONS: The study provides HSUs by sex, age, and body mass index (BMI) categories for the Ghanaian population and examines associations between HSU and high BMI. Obesity was negatively associated with health state utility in the population. These data can be used in future economic evaluations for Ghana and sub-Saharan African populations.

Chronic Noncommunicable Diseases in 6 Low- and Middle-Income Countries: Findings From Wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (SAGE).

In this paper, we examine patterns of self-reported diagnosis of noncommunicable diseases (NCDs) and prevalences of algorithm/measured test-based, undiagnosed, and untreated NCDs in China, Ghana, India, Mexico, Russia, and South Africa. Nationally representative samples of older adults aged ≥50 years were analyzed from wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (2007-2010; n = 34,149). Analyses focused on 6 conditions: angina, arthritis, asthma, chronic lung disease, depression, and hypertension. Outcomes for these NCDs were: 1) self-reported disease, 2) algorithm/measured test-based disease, 3) undiagnosed disease, and 4) untreated disease. Algorithm/measured test-based prevalence of NCDs was much higher than self-reported prevalence in all 6 countries, indicating underestimation of NCD prevalence in low- and middle-income countries. Undiagnosed prevalence of NCDs was highest for hypertension, ranging from 19.7% (95% confidence interval (CI): 18.1, 21.3) in India to 49.6% (95% CI: 46.2, 53.0) in South Africa. The proportion untreated among all diseases was highest for depression, ranging from 69.5% (95% CI: 57.1, 81.9) in South Africa to 93.2% (95% CI: 90.1, 95.7) in India. Higher levels of education and wealth significantly reduced the odds of an undiagnosed condition and untreated morbidity. A high prevalence of undiagnosed NCDs and an even higher proportion of untreated NCDs highlights the inadequacies in diagnosis and management of NCDs in local health-care systems.

Exposure to air pollution and tobacco smoking and their combined effects on depression in six low- and middle-income countries.

BackgroundLittle is known about the joint mental health effects of air pollution and tobacco smoking in low- and middle-income countries.AimsTo investigate the effects of exposure to ambient fine particulate matter pollution (PM2.5) and smoking and their combined (interactive) effects on depression.MethodMultilevel logistic regression analysis of baseline data of a prospective cohort study (n = 41 785). The 3-year average concentrations of PM2.5 were estimated using US National Aeronautics and Space Administration satellite data, and depression was diagnosed using a standardised questionnaire. Three-level logistic regression models were applied to examine the associations with depression.ResultsThe odds ratio (OR) for depression was 1.09 (95% C11.01-1.17) per 10 µg/m3 increase in ambient PM2.5, and the association remained after adjusting for potential confounding factors (adjusted OR = 1.10, 95% CI 1.02-1.19). Tobacco smoking (smoking status, frequency, duration and amount) was also significantly associated with depression. There appeared to be a synergistic interaction between ambient PM2.5 and smoking on depression in the additive model, but the interaction was not statistically significant in the multiplicative model.ConclusionsOur study suggests that exposure to ambient PM2.5 may increase the risk of depression, and smoking may enhance this effect.

Common risk factors for chronic non-communicable diseases among older adults in China, Ghana, Mexico, India, Russia and South Africa: the study on global AGEing and adult health (SAGE) wave 1.

BACKGROUND: Behavioral risk factors such as tobacco use, unhealthy diet, insufficient physical activity and the harmful use of alcohol are known and modifiable contributors to a number of NCDs and health mediators. The purpose of this paper is to describe the distribution of main risk factors for NCDs by socioeconomic status (SES) among adults aged 50 years and older within a country and compare these risk factors across six lower- and upper-middle income countries. METHODS: The study population in this paper draw from SAGE Wave 1 and consisted of adults aged 50-plus from China (N=13,157), Ghana (N=4,305), India (N=6,560), Mexico (N=2,318), the Russian Federation (N=3,938) and South Africa (N=3,836). Seven main common risk factors for NCDs were identified: daily tobacco use, frequent heavy drinking, low level physical activity, insufficient vegetable and fruit intake, high risk waist-hip ratio, obesity and hypertension. Multiple risk factors were also calculated by summing all these risk factors. RESULTS: The prevalence of daily tobacco use ranged from 7.7% (Ghana) to 46.9% (India), frequent heavy drinker was the highest in China (6.3%) and lowest in India (0.2%), and the highest prevalence of low physical activity was in South Africa (59.7%). The highest prevalence of respondents with high waist-to-hip ratio risk was 84.5% in Mexico, and the prevalence of self-reported hypertension ranging from 33% (India) to 78% (South Africa). Obesity was more common in South Africa, the Russia Federation and Mexico (45.2%, 36% and 28.6%, respectively) compared with China, India and Ghana (15.3%, 9.7% and 6.4%, respectively). China, Ghana and India had a higher prevalence of respondents with multiple risk factors than Mexico, the Russia Federation and South Africa. The occurrence of three and four risk factors was more prevalent in Mexico, the Russia Federation and South Africa. CONCLUSION: There were substantial variations across countries and settings, even between upper-middle income countries and lower-middle income countries. The baseline information on the magnitude of the problem of risk factors provided by this study can help countries and health policymakers to set up interventions addressing the global non-communicable disease epidemic.

Edentulism and quality of life among older Ghanaian adults.

BACKGROUND: Edentulism affects the quality of life and general health of an individual. But in ageing individuals, it has been observed to have greater impact, manifesting in functional, psychological and social limitations. With an increasing older adult population in Ghana, its burden is likely to increase. This study was thus carried out to explore the association between edentulism and quality of life among older Ghanaian adults. METHODS: Secondary analysis of WHO's Study on global AGEing and adult health (SAGE) Wave 1 in Ghana was conducted using self-reported edentulism as the dependent variable. Participants included a nationally representative sample of adult's aged 50 years and older living in Ghana. Quality of life was measured using the 8 item WHOQOL measure and a single item measure which was a question "How would you rate your overall quality of life?". To assess the association between edentulism and the independent variables, a bivariate analysis was carried out. A Poisson regression model was then performed, adjusting for age, sex, income, education and the diagnosis of a chronic disease condition. A Spearman's correlation analysis was also carried out between the single and multi item measure of quality of life to assess how well they correlate. RESULTS: Edentulism was observed to be associated with significantly lower levels of SWB among older adults using both the single-item and multiple-item measure (WHOQOL). It, however, showed no association with happiness. Among edentulous respondents, females and those with no formal education reported significantly lower quality of life. The WHOQOL correlated positively and strongly with the single-item measure. CONCLUSION: Edentulism may not be life threatening and yet it has been shown to have a negative effect on the quality of life of older adult Ghanaians. More emphasis may thus need to be placed on the oral health of the aging population in Ghana to avoid it.

Widowhood, Socio-Economic Status, Health and Wellbeing in Low and Middle-Income Countries.

Using data on women aged 50 and over from the WHO's Survey of Ageing and Adult Health for China, Ghana, India, the Russian Federation and South Africa (N=17,009), we assess associations between widowhood and socio-economic, health and quality of life deprivations. We find variations in the prevalence and timing of widowhood across the study countries, and associations between widowhood and being in the poorest wealth quintile for all five countries. For other deprivations, national experiences varied, with stronger and more consistent effects for India and China. These findings challenge generalised claims about widowhood and call for more contextualised analysis.

Self-reported cataracts in older adults in Ghana: sociodemographic and health related factors.

BACKGROUND: Changes in function of sensory organs with increasing age have significant impact on health and wellbeing of older persons. This paper describes cataract, a chronic eye condition, self-reported among older adults in Ghana and the need for improving access to eye care services. METHODS: This work was based on the World Health Organization's multi-country Study on global AGEing and adult health (SAGE), conducted in six countries including Ghana. SAGE Wave 1 in Ghana was conducted in 2007-2008 in a nationally representative sample of 4278 older adults, ≥ 50 years. Data were obtained on sociodemographic and health factors related to self-reported cataracts in older persons in Ghana. Data were analysed using descriptive measures (frequencies and proportions), chi-square test for associations in categorical outcome measures, and logistic regression for predictors of cataracts with SPSS version 21. RESULTS: Overall prevalence of self-reported cataracts among 4278 older adults in Ghana was 5.4%. Prevalence was proportionately higher for women (5.9%) than men (4.7%). Reported cataracts increased with age, among urban residents, in older adults living without partners and among those with the worse life satisfaction index. Older adults in lower income groups, poorly educated or living alone had difficulty seeking vision care services. Prevalence was 8.4% among persons with diabetes, 10.4% among hypertensives and 11.4% in persons with previous history of stroke. Among older persons who had ever used alcohol or tobacco, prevalence rates of reported cataracts were 5.7% and 4.9%, respectively. Logistic regression analysis indicated that increasing age, lower income status and self-reported hypertension were significantly associated with cataract among older adults in Ghana. CONCLUSIONS: Cataract is prevalent in older people in Ghana with approximately 1 in 20 people aged 50 years or older reporting a previous diagnosis of cataract. As cataract surgery is restorative, a public health approach on behavioural modification, well structured national outreach eye care services (for rural residents), inclusion of basic eye health services at sub-district levels, increased family support and national health insurance for older persons is indicated.

Validation of the COURAGE Built Environment Self-Reported Questionnaire.

UNLABELLED: The built environment (BE) impacts on people's disability and health, in terms of overweight, depression, alcohol abuse, poor self-rated health and presence of psychological symptoms; it is reasonable to assume that BE also impacts on participation levels. This paper presents the validation of the COURAGE Built Environment Self-Reported Questionnaire (CBE-SR), an instrument designed to evaluate BE in the context of health and disability. Subjects participating to COURAGE, a cross-sectional study conducted on 10,800 citizens of Poland, Finland and Spain, completed a protocol inclusive of the CBE-SR. Psychometric properties and factor structure were analysed, and factor scores created. Gender differences, differences between persons from different age groups and persons reporting the environment as facilitating, hindering or neutral were calculated. Eight items were deleted so that the final version of CBE-SR comprises 19 items. Cronbach's alpha ranged from 0.743 to 0.906, and test-retest stability was demonstrated for the majority of items. Four subscales were identified: Usability of the neighbourhood environment; Hindrance of walkable environment; Easiness of use of public buildings, places and facilities; and Risk of accidents and usability of the living place. Younger respondents reported their neighbourhood as more usable but perceived walkways as more hindering and public buildings as less easy to use; gender differences were almost inexistent. The CBE-SR is a four-scale instrument with good psychometric properties that measures the person-environment interaction. It is sensitive across age groups and is consistent with the subject's overall judgement of the degree to which the environment is facilitating or hindering. KEY PRACTITIONER MESSAGE: Poor built environments have a negative impact on the level of a person's participation. However, instruments measuring the person-environment interaction are lacking. The CBE-SR is a valid and reliable instrument that researchers can use to assess the relationships between the intrinsic health state and the objective features of the environment. Understanding this relationship would provide further insight into the need of addressing the individual's functioning either by means of interventions directed to the individual or by making changes to the individual's environment.

The COURAGE Built Environment Outdoor Checklist: an objective built environment instrument to investigate the impact of the environment on health and disability.

UNLABELLED: A tool to assess the built environment, which takes into account issues of disability, accessibility and the need for data comparable across countries and populations, is much needed. The Collaborative Research on Ageing in Europe (COURAGE) in Europe Built Environment Outdoor Checklist (CBE-OUT) helps us to understand when features of the neighbourhood environment have either a positive or negative impact on the accessibility of neighbourhoods for healthy ageing. The CBE-OUT is composed of 128 items that can be recorded when present in the evaluated environment. Audits were performed in households randomly selected from each cluster of the sample for Finland, Poland and Spain, following precise rules defined by experts. Global scores were computed both section by section and in the overall checklist, rescaling the resulting scores from 0 (negative environment) to 100 (positive). The total number of completed CBE-OUT checklists was 2452 (Finland, 245; Poland, 972; and Spain, 1235). Mean global score for our sample is 49.3, suggesting an environment composed both of facilitating and hindering features. Significant differences were observed in the built environment features of the three countries and in particular between Finland and the other two. The assessment of features of built environment is crucial when thinking about ageing and enhanced participation. The COURAGE in Europe project developed this tool to collect information on built environment in an objective evaluation of environmental features and is a recommended methodology for future studies. KEY PRACTITIONER MESSAGE: The CBE-OUT checklist is an objective evaluation of the built environment and is centred on technical measurement of features present in the environment and has its foundations in the concepts of disability and accessibility operating in the International Classification of Functioning, Disability and Health (ICF) model. The CBE-OUT checklist can be analysed using both the total score and the single section score, allowing an evaluation of the facilitating or hindering role of the environment and is usable for predictive analysis of ageing trends. The CBE-OUT checklist makes it possible to collect information about the built environment by means of an objective evaluation of environment features and is a recommended methodology for future studies about the built environment.

Erectile dysfunction, penile atherosclerosis, and coronary artery vasculopathy in heart transplant recipients.

INTRODUCTION: Vascular erectile dysfunction (ED) is the expression of a systemic vascular disease and in particular of endothelial dysfunction. Dysfunctional endothelium plays also a significant role in the onset and progression of coronary artery vasculopathy (CAV). AIM: This pilot study was designed to evaluate the prevalence and pathogenesis of ED and its correlation with CAV in heart transplanted male. METHODS: A total of 77 male heart transplanted patients (HTx) evaluated in our center (mean age 61.6 + 10.6 years) were enrolled in the study. MAIN OUTCOME MEASURES: All subjects underwent accurate medical history collection, including lifestyle (cigarette smoking, dietary and sedentary habits, drug intake, and erectile function before cardiac transplantation), physical examination (body mass index and arterial pressure), biochemical blood tests (fasting glucose, total cholesterol, high-density lipoprotein cholesterol, and triglycerides), and hormones (prolactin, luteinizing hormone and total testosterone). Furthermore, they were studied with penile, carotid, femoral echo-color Doppler ultrasonography and coronary angiogram. RESULTS: Incidence of ED was 24% before HTx and increased up to 65% after. Postischemic cardiomiopathy was an indication to HTx in ED group more frequently than in patients without ED (No-ED group) (45.1% vs. 20%). ED patients showed a lower peak systolic velocity, a higher cavernosal intima-media thickness (IMT), a higher prevalence of cavernosal plaques (26.7% vs. 5.2%, P < 0.05), peripheral vascular disease (60.87% vs. 26.1%, P < 0.05) and CAV (45.8% vs. 25.8%, P < 0.05) with respect to No-ED patients. Coronary flow reserve was significantly reduced in ED vs. No-ED patients (2.43 + 0.7 vs. 2.9 + 0.8, P < 0.04). Finally, cavernous plaque and testosterone plasma levels were statistically associated with CAV. CONCLUSIONS: We showed that ED is a frequent disease in HTx patients, more common when the original pathology is postischemic cardiomiopathy and associated with higher prevalence of cavernous plaques and CAV. Its evaluation should be integral to an HTx rehab program.

Tobacco use in older adults in Ghana: sociodemographic characteristics, health risks and subjective wellbeing.

BACKGROUND: Tobacco use over the life-course threatens to increase disease burden in older adulthood, including lower income countries like Ghana. This paper describes demographic, socioeconomic, health risks and life satisfaction indices related to tobacco use among older adults in Ghana. METHODS: This work was based on the World Health Organization's multi-country Study on global AGEing and adult health (SAGE), conducted in six countries including Ghana. Wave one of SAGE in Ghana was conducted in 2007-2008 as collaboration between WHO and the University of Ghana Medical School through the Department of Community Health. A nationally representative sample of 4305 older adults aged 50 years and above were interviewed. Associations between tobacco consumption and sociodemographic, socioeconomic, health risk and life satisfaction were evaluated using chi-square and odds ratio (OR). Logistic regression analyses, adjusted for age, sex and other variables, were conducted to determine predictors of tobacco consumption in older persons. RESULTS: Overall prevalence of current daily smokers among older adults in Ghana was 7.6%. Tobacco use (i.e. ever used tobacco) was associated with older males, (AOR = 1.10, CI 1.05-1.15), older adults residing in rural locations (AOR = 1.37, CI 1.083-1.724), and older adults who used alcohol (AOR = 1.13, CI 0.230-2.418). Tobacco use was also associated (although not statistically significant per p-values) with increased self-reporting of angina, arthritis, asthma, chronic lung disease, depression, diabetes, hypertension, and stroke. Older adults who used tobacco and with increased health risks, tended to be without health insurance (AOR = 1.41, CI 1.111-1.787). Satisfaction with life and daily living was much lower for those who use tobacco. Regional differences existed in tobacco use; the three northern regions (Upper East, Northern and Upper West) had higher proportions of tobacco use among older adults in the country. Quitting tobacco use was higher in the 70+ years age group, in women, among urban residents and in those with at least secondary education. Quitting tobacco use also increased with increasing income levels. CONCLUSIONS: Tobacco use among older adults in Ghana was associated with older men living in rural locations, chronic ill-health and reduced life satisfaction. A high proportion of older adults have stopped using tobacco, demonstrating the possibilities for effective public health interventions. Health risk reduction strategies through targeted anti-smoking health campaigns, improvement in access to health and social protection (such as health insurance) will reduce health risks among older persons who use tobacco.

Difficult colonoscopies in the propofol era.

BACKGROUND: To study the relationship between endoscopic practice and adverse events during colonoscopy under standard deep sedation induced and monitored by an anesthetist. METHODS: We investigated the routine activity of an endoscopy center at the Padova University teaching hospital. We considered not only endoscopic and cardiorespiratory complications, but also the need to use high-dose propofol to complete the procedure, and the inability to complete the procedure. Variables relating to the patient's clinical conditions, bowel preparation, the endoscopist's and the anesthetist's experience, and the duration of the procedure were input in the model. RESULTS: 617 procedures under deep sedation were performed with a 5% rate of adverse events. The average dose of propofol used was 2.6 ± 1.2 mg/kg. In all, 14 endoscopists and 42 anesthetists were involved in the procedures. The logistic regression analysis identified female gender (OR=2.3), having the colonoscopy performed by a less experienced endoscopist (OR=1.9), inadequate bowel preparation (OR=3.2) and a procedure lasting longer than 17.5 minutes (OR=1.6) as the main risk factors for complications. An ASA score of 2 carried a 50% risk reduction (OR=0.5). DISCUSSION AND CONCLUSIONS: Our model showed that none of the variables relating to anesthesiological issues influenced which procedures would prove difficult.

Investigating the Relationship between Parental Education, Asthma and Rhinitis in Children Using Path Analysis.

Parental socioeconomic position (SEP) is a known determinant of a child's health. We aimed to investigate whether a low parental education, as proxy of SEP, has a direct effect on physician-diagnosed asthma, current asthma and current allergic rhinitis in children, or whether associations are mediated by exposure to other personal or environmental risk factors. This study was a secondary data analysis of two cross-sectional studies conducted in Italy in 2006. Data from 2687 adolescents (10-14 years) were analyzed by a path analysis model using generalized structural equation modelling. Significant direct effects were found between parental education and family characteristics (number of children (coefficient = 0.6229, p < 0.001) and crowding index (1.1263, p < 0.001)) as well as with exposure to passive smoke: during pregnancy (maternal: 0.4697, p < 0.001; paternal: 0.4854, p < 0.001), during the first two years of children's life (0.5897, p < 0.001) and currently (0.6998, p < 0.001). An indirect effect of parental education was found on physician-diagnosed asthma in children mediated by maternal smoking during pregnancy (0.2350, p < 0.05) and on current allergic rhinitis mediated by early environmental tobacco smoke (0.2002; p < 0.05). These results suggest the importance of promotion of ad-hoc health policies for promoting smoking cessation, especially during pregnancy.

Mobile phones and head tumours. The discrepancies in cause-effect relationships in the epidemiological studies - how do they arise?

BACKGROUND: Whether or not there is a relationship between use of mobile phones (analogue and digital cellulars, and cordless) and head tumour risk (brain tumours, acoustic neuromas, and salivary gland tumours) is still a matter of debate; progress requires a critical analysis of the methodological elements necessary for an impartial evaluation of contradictory studies. METHODS: A close examination of the protocols and results from all case-control and cohort studies, pooled- and meta-analyses on head tumour risk for mobile phone users was carried out, and for each study the elements necessary for evaluating its reliability were identified. In addition, new meta-analyses of the literature data were undertaken. These were limited to subjects with mobile phone latency time compatible with the progression of the examined tumours, and with analysis of the laterality of head tumour localisation corresponding to the habitual laterality of mobile phone use. RESULTS: Blind protocols, free from errors, bias, and financial conditioning factors, give positive results that reveal a cause-effect relationship between long-term mobile phone use or latency and statistically significant increase of ipsilateral head tumour risk, with biological plausibility. Non-blind protocols, which instead are affected by errors, bias, and financial conditioning factors, give negative results with systematic underestimate of such risk. However, also in these studies a statistically significant increase in risk of ipsilateral head tumours is quite common after more than 10 years of mobile phone use or latency. The meta-analyses, our included, examining only data on ipsilateral tumours in subjects using mobile phones since or for at least 10 years, show large and statistically significant increases in risk of ipsilateral brain gliomas and acoustic neuromas. CONCLUSIONS: Our analysis of the literature studies and of the results from meta-analyses of the significant data alone shows an almost doubling of the risk of head tumours induced by long-term mobile phone use or latency.
