Area-level measures are often used to approximate socioeconomic status (SES) when individual-level data are not available. However, no national studies have examined the validity of these measures in approximating individual-level SES. Data came from ~ 3,471,000 participants in the Mortality Disparities in American Communities study, which links data from 2008 American Community Survey to National Death Index (through 2015). We calculated correlations, specificity, sensitivity, and odds ratios to summarize the concordance between individual-, census tract-, and county-level SES indicators (e.g., household income, college degree, unemployment). We estimated the association between each SES measure and mortality to illustrate the implications of misclassification for estimates of the SES-mortality association. Participants with high individual-level SES were more likely than other participants to live in high-SES areas. For example, individuals with high household incomes were more likely to live in census tracts (r = 0.232; odds ratio [OR] = 2.284) or counties (r = 0.157; OR = 1.325) whose median household income was above the US median. Across indicators, mortality was higher among low-SES groups (all p < .0001). Compared to county-level, census tract-level measures more closely approximated individual-level associations with mortality. Moderate agreement emerged among binary indicators of SES across individual, census tract, and county levels, with increased precision for census tract compared to county measures when approximating individual-level values. When area level measures were used as proxies for individual SES, the SES-mortality associations were systematically underestimated. Studies using area-level SES proxies should use caution when selecting, analyzing, and interpreting associations with health outcomes. 相似文献

BackgroundCOVID-19 lockdown measures have caused severe disruptions to work and education and prevented people from engaging in many rewarding activities. Cannabis users may be especially vulnerable, having been previously shown to have higher levels of apathy and anhedonia than non-users.MethodsIn this survey study, we measured apathy and anhedonia, before and after lockdown measures were implemented, in n = 256 adult and n = 200 adolescent cannabis users and n = 170 adult and n = 172 adolescent controls. Scores on the Apathy Evaluation Scale (AES) and Snaith-Hamilton Pleasure Scale (SHAPS) were investigated with mixed-measures ANCOVA, with factors user group, age group, and time, controlling for depression, anxiety, and other drug use.ResultsAdolescent cannabis users had significantly higher SHAPS scores before lockdown, indicative of greater anhedonia, compared with adolescent controls (P = .03, η p2 = .013). Contrastingly, adult users had significantly lower scores on both the SHAPS (P < .001, η p2 = .030) and AES (P < .001, η p2 = .048) after lockdown compared with adult controls. Scores on both scales increased during lockdown across groups, and this increase was significantly smaller for cannabis users (AES: P = .001, η p2 = .014; SHAPS: P = .01, η p2 = .008). Exploratory analyses revealed that dependent cannabis users had significantly higher scores overall (AES: P < .001, η p2 = .037; SHAPS: P < .001, η p2 = .029) and a larger increase in scores (AES: P = .04, η p2 =.010; SHAPS: P = .04, η p2 = .010), compared with non-dependent users.ConclusionsOur results suggest that adolescents and adults have differential associations between cannabis use as well as apathy and anhedonia. Within users, dependence may be associated with higher levels of apathy and anhedonia regardless of age and a greater increase in levels during the COVID-19 lockdown. 相似文献

SETTING: The Komfo Anokye Teaching Hospital, Kumasi, Ghana, West Africa. OBJECTIVE: To evaluate simple and commonly used parameters of the acute-phase response as correlates of successful resolution of smear-positive pulmonary tuberculosis (PTB) during drug treatment. DESIGN: Serum C-reactive protein (CRP) concentration, erythrocyte sedimentation rate (ESR), body weight, and blood haemoglobin were measured in human immunodeficiency virus (HIV) negative Ghanaian patients with PTB (n = 15) and in age- and sex-matched healthy controls (n = 15). These parameters were subsequently measured in patients after 1, 2 and 3 months of antituberculosis treatment. Serum concentrations of soluble interleukin-2-receptor-alpha (sCD25) were also measured as a comparative index of resolution of the systemic inflammatory process. RESULTS: Anti-tuberculosis treatment resulted in sputum smear conversion in all 15 patients. After one month of treatment, reductions in serum CRP concentration (>20%) and increases in haemoglobin concentration (>0.4 g/dl) occurred in the majority of patients and correlated with steep reductions in serum levels of sCD25. In contrast, weight loss and elevated ESR were slower to resolve, and were insensitive early markers of response to treatment. CONCLUSION: A fall in serum CRP and a rise in blood haemoglobin are correlates of the initial response to drug treatment of PTB. These parameters may assist in the evaluation of empiric trials of treatment in microbiologically unconfirmed cases of suspected PTB. 相似文献

Background
Interferon-gamma (IFN-γ) ELISPOT assays incorporating Mycobacterium tuberculosis-specific antigens are useful in the diagnosis of tuberculosis (TB) or latent infection. However, their utility in patients with advanced HIV is unknown. We studied determinants of ELISPOT responses among patients with advanced HIV infection (but without active TB) living in a South African community with very high TB notification rates. 相似文献99.

The public sector scale-up of antiretroviral therapy (ART) in South Africa commenced in 2004. We aimed to describe the hospital-level disease burden and factors contributing to morbidity and mortality among hospitalized HIV-positive patients in the era of widespread ART availability.Between June 2012 and October 2013, unselected patients admitted to medical wards at a public sector district hospital in Cape Town were enrolled in this cross-sectional study with prospective follow-up. HIV testing was systematically offered and HIV-infected patients were systematically screened for TB. The spectrum of admission diagnoses among HIV-positive patients was documented, vital status at 90 and 180 days ascertained and factors independently associated with death determined.Among 1018 medical admissions, HIV status was ascertained in 99.5%: 60.1% (n = 609) were HIV-positive and 96.1% (n = 585) were enrolled. Of these, 84.4% were aware of their HIV-positive status before admission. ART status was naive in 35.7%, current in 45.0%, and interrupted in 19.3%. The most frequent primary clinical diagnoses were newly diagnosed TB (n = 196, 33.5%), other bacterial infection (n = 100, 17.1%), and acquired immunodeficiency syndrome (AIDS)-defining illnesses other than TB (n = 64, 10.9%). By 90 days follow-up, 175 (29.9%) required readmission and 78 (13.3%) died. Commonest causes of death were TB (37.2%) and other AIDS-defining illnesses (24.4%). Independent predictors of mortality were AIDS-defining illnesses other than TB, low hemoglobin, and impaired renal function.HIV still accounts for nearly two-thirds of medical admissions in this South African hospital and is associated with high mortality. Strategies to improve linkage to care, ART adherence/retention and TB prevention are key to reducing HIV-related hospitalizations in this setting. 相似文献

Recovery colleges are formal learning programs that aim to support people with a lived experience of mental illness. In this study, we aimed to explore the experiences of participants in a pilot recovery college that opened in Adelaide, South Australia, in 2016. A qualitative exploratory study was conducted involving interviews with learners (n = 8) and focus groups with lived experience facilitators (course facilitators with a lived experience of mental illness, n = 5), Clinician facilitators (mental health service staff facilitators, n = 4), and care coordinators (staff providing case management support, n = 5). Three main themes (hope, identity, and the recovery college as a transition space) and two subthemes (recovery college experience and outcomes) were identified. The results showed that the recovery college provided a transition space for shifting learners' identities from patient to student, facilitated by the experiences and outcomes of the recovery college, providing hope for the future. This study highlights the importance of providing mentally healthy and non‐stigmatizing learning environments to promote and cement recovery for people with a lived experience of mental illness. 相似文献
