A Multilevel Perspective on the Health Effect of Social Capital: Evidence for the Relative Importance of Individual Social Capital over Neighborhood Social Capital.

Employing a multilevel perspective on the health effects of social capital, this study analyzes how individual and neighborhood differences in self-rated health in Ghent (Belgium), relate to individual and collective social mechanisms, when taking demographic and socioeconomic characteristics of individuals into account. This study estimates the health effects of social trust, informal social control and disorder at the neighborhood level and social support and network size at the individual level, using indicators indebted to both the normative and resource-based approaches to social capital. Instead of the mere aggregation of individual indicators of social capital, this study uses the key informant technique as a methodologically superior measurement of neighborhood social capital, which combined with a multilevel analysis strategy, allows to disentangle the health effects of individual and neighborhood social capital. The analysis highlights the health benefits of individual social capital, i.e., individual social support and network size. The study indicates that controlling for individual demographic and socioeconomic characteristics reduces the effect of the neighborhood-level counterparts and the neighborhood characteristics social trust and neighborhood disorder have significant, but small health effects. In its effects on self-rated health, social capital operates on the individual level, rather than the neighborhood level.

Evaluation of the quality of Primary Health Care services for children: reflections on the feasibility of using the Brazilian version of the Primary Care Assessment Tool as a routine assessment tool.

OBJECTIVE: To assess the quality of the Primary Health Care services provided to children and the feasibility of using the Brazilian version of Primary Care Assessment Tool (PCAT-Brazil) as a routine quality assessment tool. METHODS: A cross-sectional study was carried out in Joanópolis, a small rural town in the State of São Paulo (SP), Brazil. Seven health professionals and 502 caretakers of children using the public health center were interviewed using the PCAT-Brazil, collecting data on the core and related attributes of Primary Health Care provided to children. The score of each attribute was calculated. RESULTS: Caretakers rated as good the following attributes; "degree of affiliation", "first contact care - use of services", "coordinated care", and "comprehensive care - available services". The attributes of "first contact accessibility", "long term person care", "comprehensive care - offered services" and "family- and community-oriented care" were scored as poor. The health professionals only rated the attribute of "first contact accessibility" as satisfactory, and considered that all other Primary Health Care attributes needed improvement. To conduct this study, at least 1,241 working hours were invested, and the estimated budget was R$12.900,00 (or U$3,953.00). CONCLUSION: The use of the PCAT-Brazil as a routine assessment and planning tool seemed to be not feasible in the given setting due to high costs, lack of trained personnel and the huge workload. To overcome the encountered obstacles, advices are given based on field experience.

RESUMO Objetivo Avaliar a qualidade dos serviços de Atenção Primária à Saúde prestados às crianças e a viabilidade de usar a versão brasileira da Primary Care Assessment Tool (PCAT-Brazil) como ferramenta rotineira de avaliação da qualidade. Métodos Estudo transversal, realizado em Joanópolis, um pequeno município rural no Estado de São Paulo. Sete profissionais de saúde e 502 responsáveis legais de crianças que usaram o centro de saúde foram entrevistados usando a PCAT-Brazil, para coleta de dados sobre os atributos essenciais e derivados dos serviços de Atenção Primária à Saúde oferecidos às crianças. Foi calculado o escore para cada atributo. Resultados Os responsáveis classificaram como satisfatórios os atributos como "grau de afiliação", "acesso de primeiro contato − utilização", "coordenação" e "integralidade − serviços disponíveis". Os atributos "acesso de primeiro contato − acessibilidade", "longitudinalidade", "integralidade − serviços prestados" e "orientação familiar e comunitária" foram classificados como insatisfatórios. Por outro lado, os profissionais de saúde apenas classificaram o atributo "acessibilidade do primeiro contato" como satisfatório e consideraram todos os outros atributos de Atenção Primária à Saúde como necessidade de melhoria. Para realizar este estudo, foram investidas pelo menos 1.241 horas de trabalho e o orçamento estimado foi de R$12.900,00 (ou U$3,953.00). Conclusão Usar a PCAT-Brazil como ferramenta de avaliação e planejamento de rotina pareceu não ser viável neste estudo, pelos altos custos, pela falta de pessoal treinado e pelo grande número de horas de trabalho exigido. Para superar os obstáculos encontrados, conselhos foram formulados com base na experiência de campo.

The role of socioeconomic status in the relationship between detention and self-rated health among prison detainees in Belgium.

Prisoners are known to report worse health than the general population. Research has also shown that the prison population counts disproportionally more people with a lower socioeconomic status (SES), making it difficult to determine whether the worse self-reported health of prisoners is an effect of their detention or of their lower SES. This study assesses the influence of being in prison on self-rated health and if (and how) this relationship is mediated by SES. Data from detainees were collected in 12 Flemish prisons. To compare with the general population, data from the Belgian national health survey 2013 were used. To estimate the direct and indirect effect of being in prison on self-reported health, mediation analysis was carried out by means of natural effect models using nested counterfactuals. Following previous literature we find that prisoners report worse health than the general population and that SES has a significant influence on subjective health. Our results showed that the direct effect (exp(B) = 3.43; [95% CI: 2.924-4.024]) of being in prison on self-reported health is larger than the indirect effect (through SES) (exp(B) = 1,236; [95% CI: 1.195-1.278]), thus contradicting the hypotheses in previous literature that the SES is the main explanation for variation in self-reported health among prisoners. Lastly, the effect of SES on health is more important for the general population compared to detainees, suggesting that for prisoners the effect of being in prison seems to surpass the effect of SES on health.

Do We Reap What We Sow? Exploring the Association between the Strength of European Primary Healthcare Systems and Inequity in Unmet Need.

Access to healthcare is inequitably distributed across different socioeconomic groups. Several vulnerable groups experience barriers in accessing healthcare, compared to their more wealthier counterparts. In response to this, many countries use resources to strengthen their primary care (PC) system, because in many European countries PC is the first entry-point to the healthcare system and plays a central role in the coordination of patients through the healthcare system. However it is unclear whether this strengthening of PC leads to less inequity in access to the whole healthcare system. This study investigates the association between strength indicators of PC and inequity in unmet need by merging data from the European Union Statistics on Income and Living Conditions database (2013) and the Primary Healthcare Activity Monitor for Europe (2010). The analyses reveal a significant association between the Gini coefficient for income inequality and inequity in unmet need. When the Gini coefficient of a country is one SD higher, the social inequity in unmet need in that particular country will be 4.960 higher. Furthermore, the accessibility and the workforce development of a country's PC system is inverse associated with the social inequity of unmet need. More specifically, when the access- and workforce development indicator of a country PC system are one standard deviation higher, the inequity in unmet healthcare needs are respectively 2.200 and 4.951 lower. Therefore, policymakers should focus on reducing income inequality to tackle inequity in access, and strengthen PC (by increasing accessibility and better-developing its workforce) as this can influence inequity in unmet need.

Study protocol: SWING--social capital and well-being in neighborhoods in Ghent.

BACKGROUND: Investing in social capital has been put forth as a potential lever for policy action to tackle health inequity. Notwithstanding, empirical evidence that supports social capital's role in the existence of health inequity is limited and inconclusive. Furthermore, social capital literature experiences important challenges with regard to (1) the level on which social capital is measured and analyzed; (2) the measurement of the concept in line with its multidimensional nature; and (3) the cross-cultural validity of social capital measurements. The Social capital and Well-being In Neighborhoods in Ghent (SWING) study is designed to meet these challenges. The collected data can be used to investigate the distribution of health problems and the association between social capital, health and well-being, both at the individual and at the neighborhood level. The main goals of the SWING study are (1) to develop a coherent multilevel dataset of indicators on individual and neighborhood social capital and well-being that contains independent indicators of neighborhood social capital at a low level of aggregation and (2) to measure social capital as a multidimensional concept. The current article describes the background and design of the SWING study. METHODS/DESIGN: The SWING study started in 2011 and data were collected in three cross-sectional waves: the first in 2011, the second in 2012, and the third in 2013. Data collection took place in 142 neighborhoods (census tract level) in the city of Ghent (Flanders, Belgium). Multiple methods of data collection were used within each wave, including: (1) a standardized questionnaire, largely administered face-to-face interviews for neighborhood inhabitants (N = 2,730); (2) face-to-face interviews with key informants using a standardized questionnaire (N = 2,531); and (3) an observation checklist completed by the interviewers (N = 2,730 in total). The gathered data are complemented by data available within administrative data services. DISCUSSION: The opportunities and ambitions of the SWING study are discussed, together with the limitations of the database.

How equal is the relationship between individual social capital and psychological distress? A gendered analysis using cross-sectional data from Ghent (Belgium).

BACKGROUND: Social capital has been related to various aspects of health. While literature suggests that men and women differently access and mobilize social capital, gender has received little attention within social capital research. This study examines whether the association between individual social capital and psychological distress is different for men and women. METHODS: We made use of data from a representative sample of 1025 adults within 50 neighbourhoods of Ghent (Belgium), collected in the context of the cross-sectional Social capital and Well-being In Neighbourhoods in Ghent (SWING) Survey 2011. Six components of social capital were discerned: generalized trust, social support, social influence, social engagement and attachment, the volume of social capital and the mean occupational prestige in one's network. Multilevel linear regression models were fitted to explore interactions between gender and these components of social capital. RESULTS: In accordance with previous research, men report lower levels of psychological distress than women (t = 4.40, p < 0.001). Regarding the gender gap in social capital, the findings are mixed. Only for half of the social capital variables (social support, social influence and volume of social capital), a significant gender difference is found, favouring men (t = 4.03, p < 0.001; t = 1.99, p < 0.001 and t = 4.50, p < 0.001 respectively). None of the analysed interaction terms between gender and social capital is significantly related to psychological distress. CONCLUSION: The analyses indicate that the association between individual social capital and psychological distress is similar for men and women. The relatively low level of gender stratification in Belgium might have influenced this finding. Furthermore, it is possible that social capital is not of greater importance for women in general, but mainly for women who are in an especially vulnerable social situation that deprives their access to alternative resources (e.g. unemployed women, single mothers). Future studies should seek to identify subgroups for whom social capital might be particularly influential, by transcending 'simple' dyads such as 'men versus women'.

Neighborhood differences in social capital in Ghent (Belgium): a multilevel approach.

BACKGROUND: Little research has focused on the spatial distribution of social capital, despite social capital's rising popularity in health research and policy. This study examines the neighborhood differences in social capital and the determinants that explain these differences. METHODS: Five components of neighborhood social capital are identified by means of factor and reliability analyses using data collected in the cross-sectional SWING study from 762 inhabitants in 42 neighbourhoods in the city of Ghent (Belgium). Neighborhood differences in social capital are explored using hierarchical linear models with cross-level interactions. RESULTS: Significant neighborhood differences are found for social cohesion, informal social control and social support, but not for social leverage and generalized trust. Our findings suggest that neighborhood social capital depends on both characteristics of individuals living in the neighborhood (attachment to neighborhood) and characteristics of the neighborhood itself (deprivation and residential turnover). Our analysis further shows that neighborhood deprivation reinforces the negative effect of declining neighborhood attachment on social cohesion and informal social control. CONCLUSIONS: This study foregrounds the importance of contextual effects in encouraging neighborhood social capital. Given the importance of neighborhood-level characteristics, it can be anticipated social capital promoting initiatives are likely to be more effective when tailored to specific areas. Second, our analyses show that not all forms of social capital are influenced by contextual factors to the same extent, implying that changes in neighborhood characteristics are conducive to, say, trust while leaving social support unaffected. Finally, our analysis has demonstrated that complex interrelationships between individual- and neighborhood-level variables exist, which are often overlooked in current work.

Single-dose pharmacokinetics of pediatric and adult formulations of etravirine and swallowability of the 200-mg tablet: results from three Phase 1 studies.

OBJECTIVES: Three studies were conducted to assess the pharmacokinetics, methods of administration and ease of swallowability of etravirine tablets. METHODS: Two randomized studies in healthy adults investigated the single-dose pharmacokinetics of etravirine in various dosage strengths and the effects of dispersion in water and film-coating. A third study explored swallowability of etravirine 200-mg tablets in HIV-infected patients. First study: 37 volunteers received 1 × 100-mg non-coated tablet (reference), 4 × 25-mg noncoated tablets and 1 × 100-mg non-coated tablet dispersed in 100 ml water. Second study: 24 volunteers received 2 × 100-mg non-coated tablets (reference), 2 × 100-mg coated tablets, 1 × 200-mg non-coated and 1 × 200-mg coated tablet. Pharmacokinetic parameters were determined using non-compartmental analysis and least square means (LSM) ratios and 90% confidence intervals (CI) were calculated. Third study: 49 virologically-suppressed patients already on an etravirine-containing regimen rated the swallowability of two etravirine formulations (200-mg non-coated and 200-mg coated tablets). RESULTS: In the first study LSM ratios (90% CI) for the etravirine area under the plasma concentration-time curve (AUC) administered either as 4 × 25-mg tablets or 100-mg tablet dispersed were: 0.91 (0.85 to 0.98) and 0.97 (0.90 to 1.03), respectively. In the second study, when comparing a 200-mg non-coated and coated tablet to 2 × 100-mg non-coated tablets, LSM ratios for etravirine AUC were 98 to 99%. In the third study, more patients rated the 200-mg than the 100-mg tablets as acceptable to swallow (70% vs. 43%). CONCLUSIONS: Comparable etravirine exposures were observed regardless of formulation or method of administration (i.e., dispersion); 200-mg tablets were rated as easier to swallow than 100-mg tablets.

Steady-state pharmacokinetics of etravirine and lopinavir/ritonavir melt extrusion formulation, alone and in combination, in healthy HIV-negative volunteers.

BACKGROUND: A previous study investigating coadministration of etravirine, a nonnucleoside reverse transcriptase inhibitor, and lopinavir/ritonavir soft-gel formulation resulted in nonclinically relevant changes in etravirine and lopinavir exposure. The current study evaluated the pharmacokinetic interaction between etravirine and the lopinavir/ritonavir melt extrusion formulation. METHOD: Sixteen human immunodeficiency virus (HIV)-negative volunteers were randomized to either treatment sequence A/B or B/A, with 14 days- washout between treatments (treatment A: etravirine 200 mg bid for 8 days; treatment B: lopinavir/ritonavir 400/100 mg bid for 16 days with etravirine 200 mg bid on days 9-16). Steady-state pharmacokinetics were assessed for all antiretrovirals alone and coadministered; pharmacokinetic parameters were obtained by noncompartmental analysis. Safety and tolerability were assessed. RESULTS: Coadministration of etravirine and lopinavir/ritonavir resulted in a 35% decrease in etravirine exposure. Smaller decreases (<13%) were observed in lopinavir and ritonavir exposure. Six volunteers reported headache; 1 grade 3 triglyceride increase was reported. CONCLUSION: Lopinavir/ritonavir induced etravirine metabolism to a similar extent as most other boosted HIV protease inhibitors. The short-term coadministration of etravirine and lopinavir/ritonavir was well tolerated and did not lead to increased incidences of adverse events.

Pharmacokinetics and short-term safety of etravirine in combination with fluconazole or voriconazole in HIV-negative volunteers.

The nonnucleoside reverse transcriptase inhibitor etravirine, approved for use in treatment-experienced, HIV-1-infected patients, is a substrate and inducer of cytochrome P450 (CYP) 3A4 and a substrate and inhibitor of CYP2C9/CYP2C19. Pharmacokinetic interactions and safety of etravirine 200 mg twice daily coadministered with fluconazole 200 mg daily or voriconazole 200 mg twice daily, both inhibitors of CYP3A4, CYP2C9, and CYP2C19, were evaluated in an open-label, randomized, 3-period crossover trial in 18 HIV-negative volunteers. Based on least squares means (LSM) ratios, coadministration of etravirine with fluconazole or voriconazole resulted in higher etravirine exposures (area under plasma concentration-time curve from 0-12 hours [AUC(12) (h) ] 1.86- and 1.36-fold, respectively). Fluconazole pharmacokinetics were unchanged with etravirine coadministration (AUC(12) (h) LSM ratio: 0.94), and voriconazole plasma concentrations were slightly raised (AUC(12) (h) LSM ratio: 1.14). All treatments and combinations were well tolerated, with no grade 3 or 4 adverse events observed during treatment. There was 1 adverse event-related trial withdrawal during treatment with fluconazole alone (leukocyturia). The most frequent adverse events were headache and blurred vision (11 and 8 volunteers, respectively), with blurred vision occurring exclusively during voriconazole-alone treatment. Pharmacokinetic interactions between etravirine and fluconazole or voriconazole are not expected to be clinically relevant; no dose adjustments are required during coadministration.

Does neighbourhood social capital aid in levelling the social gradient in the health and well-being of children and adolescents? A literature review.

BACKGROUND: Although most countries in the European Union are richer and healthier than ever, health inequalities remain an important public health challenge. Health-related problems and premature death have disproportionately been reported in disadvantaged neighbourhoods. Neighbourhood social capital is believed to influence the association between neighbourhood deprivation and health in children and adolescents, making it a potentially interesting concept for policymakers. METHODS: This study aims to review the role of social capital in health inequalities and the social gradient in health and well-being of children and adolescents. A systematic review of published quantitative literature was conducted, focussing on (1) the mediating role of neighbourhood social capital in the relationship between socio-economic status (SES) and health-related outcomes in children and adolescents and (2) the interaction between neighbourhood social capital and socio-economic characteristics in relation to health-related outcomes in children and adolescents. Three electronic databases were searched. Studies executed between 1 January 1990 and 1 September 2011 in Western countries (USA, New Zealand, Australia and Europe) that included a health-related outcome in children or adolescents and a variable that measured neighbourhood social capital were included. RESULTS: Eight studies met the inclusion criteria for the review. The findings are mixed. Only two of five studies confirmed that neighbourhood social capital mediates the association between neighbourhood deprivation and health and well-being in adolescents. Furthermore, two studies found a significant interaction between neighbourhood socio-economic factors and neighbourhood social capital, which indicates that neighbourhood social capital is especially beneficial for children who reside in deprived neighbourhoods. However, two other studies did not find a significant interaction between SES and neighbourhood social capital. Due to the broad range of studied health-related outcomes, the different operationalisations of neighbourhood social capital and the conceptual overlap between measures of SES and social capital in some studies, the factors that explain these differences in findings remain unclear. CONCLUSIONS: Although the findings of this study should be interpreted with caution, the results suggest that neighbourhood social capital might play a role in the health gradient among children and adolescents. However, only two of the included studies were conducted in Europe. Furthermore, some studies focussed on specific populations and minority groups. To formulate relevant European policy recommendations, further European-focussed research on this issue is needed.

Geriatric day hospital: opportunity or threat? A qualitative exploratory study of the referral behaviour of Belgian general practitioners.

BACKGROUND: In order to address the challenges of an ageing population the Belgian government decided to allocate resources to the creation of geriatric day hospitals (GDHs). Although GDHs are meant to be a strategy to support general practitioners (GPs) caring for the frail elderly, few Belgian GPs seem to refer to a GDH. This study aims to explore the barriers and facilitating factors of GPs' referral to GDHs. METHODS: A qualitative study using focus group discussions (FGDs) was conducted. Fifteen FGDs were organized in the different Belgian regions (Flanders, Wallonia, Brussels). RESULTS: Contextual factors such as the unsatisfactory cooperation between hospital and GPs and organizational barriers such as the lack of communication on referral procedures between hospital and primary health care (PHC) were identified. Lack of basic knowledge about the concept or the local organization of GDH seemed to be a problem. Unclear task descriptions, responsibilities and activities of a GDH formed prominent points of discussion in all FGDs. Nevertheless a lot of possible advantages and disadvantages of GDHs for the patient and for the GP were mentioned. CONCLUSIONS: In the case of poor referral to GDHs, focusing on improving overall collaboration between primary and secondary health care is essential. This can be achieved by actively delivering adequate information, permanent communication and more involvement of PHC in the organization and functioning of GDHs. The absence of a transparent health care system with delineated role definitions, seems to hinder the integration of new initiatives like GDHs in the care process. Strategies to enhance referral to GDHs should use a comprehensive approach.

Effects of different meal compositions and fasted state on the oral bioavailability of etravirine.

STUDY OBJECTIVE: To determine the effects of various meal compositions and the fasted state on the pharmacokinetics of etravirine, a nonnucleoside reverse transcriptase inhibitor. DESIGN: Phase I, open-label, randomized, repeated single-dose, three-period crossover trial. SETTING: Clinical pharmacology unit. PARTICIPANTS: Two parallel panels of 12 human immunodeficiency virus (HIV)-negative, healthy, male volunteers. Twenty volunteers completed the study; three withdrew consent, and one was lost to follow-up. Intervention. Panel 1 received a single dose of etravirine 100 mg after a standard breakfast, in the fasted state, and after a light breakfast (croissant). Panel 2 received the same treatment after a standard breakfast, after an enhanced-fiber breakfast, and after a high-fat breakfast. Each treatment was separated by a washout period of at least 14 days. MEASUREMENTS AND MAIN RESULTS: For each treatment, full pharmacokinetic profiles of etravirine were determined up to 96 hours after dosing. Pharmacokinetic parameters were determined by noncompartmental methods and analyzed using a linear mixed-effects model for a crossover design. The least-squares mean ratio for the area under the plasma concentration-time curve from time of administration to the last time point with a measurable concentration after dosing (AUClast) was 0.49 (90% confidence interval [CI] 0.39-0.61) for the fasted state compared with dosing after a standard breakfast. When dosing occurred after a light or enhanced-fiber breakfast, the corresponding values were 0.80 (90% CI 0.69-0.94) and 0.75 (90% CI 0.63-0.90), respectively. When administered after a high-fat breakfast the least-squares mean ratio of AUC(last) was 1.09 (0.84-1.41), compared with dosing after a standard breakfast. Adverse events were also assessed. Under all conditions, single doses of etravirine 100 mg were generally safe and well tolerated. CONCLUSION: Administration of etravirine in a fasted state resulted in 51% lower mean exposure compared with dosing after a standard breakfast. Etravirine should be administered following a meal to improve bioavailability; however, differences in exposure after a standard breakfast versus a high-fat, enhanced-fiber, or light breakfast (croissant) were not considered clinically relevant.
