Racial/ethnic discrimination and common mental disorders among workers: findings from the EMPIRIC Study of Ethnic Minority Groups in the United Kingdom

OBJECTIVES: We measured perceived discrimination and its association with common mental disorders among workers in the United Kingdom. METHODS: We conducted a secondary analysis of a national sample of 6 ethnic groups (n=2054). Discrimination was measured as reports of insults; unfair treatment at work; or job denial stemming from race, religion, or language. The outcome assessed was presence of common mental disorders. RESULTS: The risk of mental disorders was highest among ethnic minority individuals reporting unfair treatment (odds ratio [OR]=2.0; 95% confidence interval [CI]=1.2, 3.2) and racial insults (OR=2.3; 95% CI=1.4, 3.6). The overall greatest risks were observed among Black Caribbeans exposed to unfair treatment at work (OR=2.9; 95% CI=1.2, 7.3) and Indian (OR=3.1; 95% CI=1.4, 7.2), Bangladeshi (OR=32.9; 95% CI=2.5, 436.0), and Irish (OR=2.9; 95% CI=1.1, 7.6) individuals reporting insults. CONCLUSIONS: Racial/ethnic discrimination shows strong associations with common mental disorders.     

Associations of neighborhood characteristics with the location and type of food stores

OBJECTIVES: We investigated associations between local food environment and neighborhood racial/ethnic and socioeconomic composition. METHODS: Poisson regression was used to examine the association of food stores and liquor stores with racial/ethnic composition and income in selected census tracts in North Carolina, Maryland, and New York. RESULTS: Predominantly minority and racially mixed neighborhoods had more than twice as many grocery stores as predominantly White neighborhoods (for predominantly Black tracts, adjusted stores per population ratio [SR]=2.7; 95% confidence interval [CI]=2.2, 3.2; and for mixed tracts, SR=2.2; 95% CI=1.9, 2.7) and half as many supermarkets (for predominantly Black tracts, SR=0.5; 95% CI=0.3, 0.7; and for mixed tracts, SR=0.7; 95% CI=0.5, 1.0, respectively). Low-income neighborhoods had 4 times as many grocery stores as the wealthiest neighborhoods (SR=4.3; 95% CI=3.6, 5.2) and half as many supermarkets (SR=0.5; 95% CI=0.3, 0.8). In general, poorer areas and non-White areas also tended to have fewer fruit and vegetable markets, bakeries, specialty stores, and natural food stores. Liquor stores were more common in poorer than in richer areas (SR=1.3; 95% CI=1.0, 1.6). CONCLUSIONS: Local food environments vary substantially by neighborhood racial/ethnic and socioeconomic composition and may contribute to disparities in health.     

Likelihood of home death associated with local rates of home birth: influence of local area healthcare preferences on site of death

Objectives. We tested whether local cultural and social values regarding the use of health care are associated with the likelihood of home death, using variation in local rates of home births as a proxy for geographic variation in these values.

Methods. For each of 351110 adult decedents in Washington state who died from 1989 through 1998, we calculated the home birth rate in each zip code during the year of death and then used multivariate regression modeling to estimate the relation between the likelihood of home death and the local rate of home births.

Results. Individuals residing in local areas with higher home birth rates had greater adjusted likelihood of dying at home (odds ratio [OR]=1.04 for each percentage point increase in home birth rate; 95% confidence interval [CI] = 1.03, 1.05). Moreover, the likelihood of dying at home increased with local wealth (OR=1.04 per $10000; 95% CI=1.02, 1.06) but decreased with local hospital bed availability (OR=0.96 per 1000 beds; 95% CI=0.95, 0.97).

Conclusions. The likelihood of home death is associated with local rates of home births, suggesting the influence of health care use preferences.

     

The Effects of Religious Attendance and Obesity on Health by Race/Ethnicity

ObjectivesThe objectives of this paper are to examine the effects of religion and obesity on health and determine how the relationship varies by racial/ethnic groups with data from the Panel Study of American Race and Ethnicity (PS-ARE).MethodsUsing ordinal logistic regression, the effects of religion and obesity on self-rated health and how the relationship varies by racial/ethnic groups are investigated. Additionally, to determine whether certain ethnic groups are more impacted by the frequency of religious attendance and obesity, whites, blacks, and Hispanics are analyzed separately with ordinal logistic regression.ResultsWhen obesity was added in focal relationship between religious services attendance and self-rated health strengthened this focal relationship which is a suppression effect between religious services attending and self-rated health adding obesity. For BMI is also significantly associated with decreased odds of reporting better health–normal weight (OR = 2.99; 95% CI = 2.43–3.67) and overweight (OR = 2.19; 95% CI = 1.79–2.68) compared to obese. Subjects who attend religious services 1–2 time a year (OR = 1.30; 95% CI = 1.04–1.62) and 1–3 times a month (OR = 1.28; 95% CI = 1.05–1.57) are associated with increased odds of reporting better health. In whites, attending religious services 1–2 times a year are associated with increased odds of reporting better health (OR = 1.48; 95% CI = 1.09–2.00) and 1–3 times a month are also associated with increased odds of reporting health (OR = 1.34; 95% CI = 1.02–1.78) compared to never attending religious attendance. The frequency of religious services attendance of blacks and Hispanics are not associated with self-rated health. For BMI, being white is more positively associated with increased odds of reporting better health than black and Hispanic subjects. Although white subjects are less likely to attend religious services more frequently than black and Hispanic subjects, the influence on self-rated health in white subjects is more evidenced than other racial/ethnic groups.ConclusionsAlthough it was not proven that the association between participation in religious services and self-rated health is mediated by obesity, the research shows the suppression effect of obesity between participation in religious services and self-rated health.     

Use of alcohol,tobacco and illicit drugs among ethnic Norwegian and ethnic minority adolescents in Hordaland county,Norway: the youth@hordaland-survey

Objective: To describe potential differences in unhealthy behaviours among ethnic Norwegian adolescents and minority adolescents from countries within the European Union, European Economic Area or US (EU/EEA countries) and adolescents from non-EU/EEA countries. Specifically, we aimed to investigate ethnic differences in use of alcohol, tobacco and illicit drugs, and potential confounding due to socio-demographic characteristics.

Design: Cross-sectional population-based study of adolescents aged 16–19 (N?=?10,122), with self-reported ethnicity as grouping variable, and self-reported use of alcohol, tobacco and illicit drugs as dependent variables.

Results: We found that minority adolescents from EU/EEA and non-EU/EEA countries differed from ethnic Norwegian adolescents on important indicators of unhealthy behaviours. Compared to Norwegian adolescents, adolescents from EU/EEA were more likely to report having tried to smoke, to be a daily smoker and to ever having tried an illicit drug (adjusted odds ratio (OR) ranging from 2.01 to 3.74). They were, however, less likely to have tried snus (a form of smokeless tobacco; adjusted OR 0.64; confidence interval (CI) 95% 0.43–0.97) and to report daily snus use (adjusted OR 0.31; CI95% 0.15–0.67). There were no differences in having tried alcohol. Non-EU/EEA adolescents were less likely to have ever tried alcohol (OR 0.24; CI95% 0.18–0.31), snus (OR 0.47; CI95% 0.34–0.65) and to smoke (0.68; CI95% 0.52–0.91), and less likely to report daily snus use (OR 0.36; CI95% 0.21–0.62) compared to Norwegian adolescents. There were no differences with regard to having tried illicit drugs and reporting being a daily smoker. All differences observed were robust to adjustment for age, gender and family socio-economic status.

Conclusion: The presents study identified important differences in unhealthy behaviours across different ethnic groups in Norway. The differences in the prevalence of unhealthy behaviours among ethnic minorities are still relevant in a public health perspective, and potential mechanisms should be investigated further.     

Is ethnic density associated with health in a context of social disadvantage? Findings from the Born in Bradford cohort

Objectives. In this study we aimed to test the associations between area-level ethnic density and health for Pakistani and White British residents of Bradford, England.

Design. The sample consisted of 8610 mothers and infant taking part in the Born in Bradford cohort. Ethnic density was measured as the percentage of Pakistani, White British or South Asian residents living in a Lower Super Output Area. Health outcomes included birth weight, preterm birth and smoking during pregnancy. Associations between ethnic density and health were tested in multilevel regression models, adjusted for individual covariates and area deprivation.

Results. In the Pakistani sample, higher own ethnic density was associated with lower birth weight (β = ?0.82, 95% CI: ?1.63, ?0.02), and higher South Asian density was associated with a lower probability of smoking during pregnancy (OR = 0.99, 95% CI: 0.98, 1.00). Pakistani women in areas with 50?70% South Asian residents were less likely to smoke than those living in areas with less than 10% South Asian residents (OR = 0.39, 95% CI: 0.16, 0.97). In the White British sample, neither birth weight nor preterm birth was associated with own ethnic density. The probability of smoking during pregnancy was lower in areas with 10?29.99% compared to <10% South Asian density (OR = 0.79, 95% CI: 0.64, 0.98).

Conclusion. In this sample, ethnic density was associated with lower odds of smoking during pregnancy but not with higher birth weight or lower odds of preterm birth. Possibly, high levels of social disadvantage inhibit positive effects of ethnic density on health.     

Differences in cardiovascular disease mortality associated with body mass between Black and White persons

We analyzed cardiovascular disease mortality risks associated with obesity using participant-level meta-analysis of data from the Black Pooling Project for Black and White individuals. The adjusted relative risks (ARRs) were stronger among White participants than among Black participants for coronary heart disease AAR=1.21 (95% confidence interval [CI]=1.07, 1.36) versus 0.87 (95% CI=0.69, 1.09), respectively, and cardiovascular disease ARR=1.18 (95% CI=1.07, 1.29) versus 0.91 (95% CI=0.77, 1.05), respectively. The results suggest that obesity is an independent risk factor in White people, and additional study of body size and disease progression is necessary in the assessment of racial disparities.     

The influence of breast self-examination on subsequent mammography participation

OBJECTIVES: We evaluated whether breast self-examination (BSE) influences subsequent mammography participation. METHODS: We evaluated associations between BSE and subsequent mammography participation, adjusting for baseline screening behaviors and sociodemographic, health, and lifestyle characteristics, among women aged 40 years and older using data from the longitudinal Canadian National Population Health Survey. RESULTS: Regular performance of BSE at baseline was not associated with receipt of a recent mammogram at follow-up among all women (adjusted odds ratio [OR]=1.01; 95% confidence interval [CI]= 0.75, 1.35) or with mammography uptake among the subgroup of women reporting never use at baseline (adjusted OR=0.78; 95% CI=0.50, 1.22). CONCLUSIONS: The lack of association between performance of BSE and subsequent mammography participation suggests that not recommending BSE is unlikely to influence mammography participation.     

Rethinking race/ethnicity, income, and childhood asthma: racial/ethnic disparities concentrated among the very poor

OBJECTIVE: Past studies of the prevalence of childhood asthma have yielded conflicting findings as to whether racial/ethnic disparities remain after other factors, such as income, are taken into account. The objective of this study was to examine the association of race/ethnicity and family income with the prevalence of childhood asthma and to assess whether racial/ethnic disparities vary by income strata. METHODS: Cross-sectional data on 14,244 children aged <18 years old in the 1997 National Health Interview Survey were examined. The authors used logistic regression to analyze the independent and joint effects of race/ethnicity and income-to-federal poverty level (FPL) ratio, adjusting for demographic covariates. The main outcome measure was parental report of the child having ever been diagnosed with asthma. RESULTS: Bivariate analyses, based on weighted percentages, revealed that asthma was more prevalent among non-Hispanic black children (13.6%) than among non-Hispanic white children (11.2%; p<0.01), but the prevalence of asthma did not differ significantly between Hispanic children (10.1%) and non-Hispanic white children (11.2%; p=0.13). Overall, non-Hispanic black children were at higher risk for asthma than non-Hispanic white children (adjusted odds ratio [OR]=1.20; 95% confidence interval [CI] 1.03, 1.40), after adjustment for sociodemographic variables, including the ratio of annual family income to the FPL. Asthma prevalence did not differ between Hispanic children and non-Hispanic white children in adjusted analyses (adjusted OR=0.85; 95% CI 0.71, 1.02). Analyses stratified by income revealed that only among children from families with incomes less than half the FPL did non-Hispanic black children have a higher risk of asthma than non-Hispanic white children (adjusted OR=1.99; 95% CI 1.09, 3.64). No black vs. white differences existed at other income levels. Subsequent analyses of these very poor children that took into account additional potentially explanatory variables did not attenuate the higher asthma risk for very poor non-Hispanic black children relative to very poor non-Hispanic white children. CONCLUSIONS: Non-Hispanic black children were at substantially higher risk of asthma than non-Hispanic white children only among the very poor. The concentration of racial/ethnic differences only among the very poor suggests that patterns of social and environmental exposures must overshadow any hypothetical genetic risk.     

Racial/Ethnic Differences in the Correlates of Mental Health Services Use among Pregnant Women with Depressive Symptoms

Objectives To examine correlates of lifetime mental health services (MHS) use among pregnant women reporting prenatal depressive symptoms by race/ethnicity. Methods This cross-sectional population-based study included 81,910 pregnant women with prenatal depressive symptoms using data from the Florida Healthy Start prenatal screening program (2008–2012). Multivariable logistic regression was conducted to ascertain adjusted odds ratios and corresponding 95 % confidence intervals for racial/ethnic differences in the correlates of lifetime MHS use. Results Findings of this study revealed racial/ethnic differences in MHS use among women with prenatal depressive symptoms, the highest rates being among non-Hispanic Whites and the lowest rates among Mexicans and other Hispanics. Most need for care factors, including illness, tobacco use, and physical or emotional abuse, consistently predicted MHS use across racial/ethnic groups after adjusting for covariates. Adjusted associations between predisposing and enabling/restricting factors and MHS use were different for different racial/ethnic groups. Conclusions Racial/ethnic differences in MHS use were found, with pregnant Hispanic women reporting prenatal depressive symptoms being the least likely to use MHS. Our study findings have significant public health implications for targeted intervention for pregnant women with prenatal depressive symptoms.     

Effect of educational level and minority status on nursing home choice after hospital discharge

Objectives. The movement to publicly report data on provider quality to inform consumer choices is predicated on assumptions of equal access and knowledge. We examine the validity of this assumption by testing whether minority/less educated Medicare patients are at greater risk of being discharged from a hospital to the lowest-quality nursing homes in a geographic area.

Methods. We used the 2002 national Minimum Data Set to identify 62601 new Medicare admissions to nursing homes in 95 hospital service areas with at least 4 freestanding nursing homes and at least 50 African Americans aged 65 years or older with Medicare admissions to nursing homes.

Results. The probability of African Americans’ being admitted to nursing homes in the lowest-quality quartile in the area was greater (relative risk [RR]=1.26; 95% confidence interval [CI]=1.0, 8.45) in comparison with Whites. Individuals without a high-school degree were also more likely to be admitted to a low-quality nursing home (RR=1.22; 95% CI=1.0, 1.46).

Conclusions. African American and poorly educated patients enter the worst-quality nursing facilities. This finding raises concerns about the usefulness of the current public reporting model for certain consumers.

     

Rate of breast cancer diagnoses among postmenopausal women with self-reported breast symptoms

BACKGROUND: Breast cancer rates in women with multiple breast symptoms have not been well described. METHODS: We examined the association between self-reported symptoms (lump, nipple discharge, pain, other) and breast cancer risk for screening and diagnostic mammograms in 57,681 women. Subanalyses evaluated risk among women with no prior mammograms, new symptoms, and repeated symptoms. One thousand, three hundred and eighty-nine women were diagnosed with cancer within 12 months of their mammograms. We calculated the breast cancer rate for each symptom and odds ratios (OR) with 95% confidence intervals (CI) for breast cancer among symptomatic women compared with asymptomatic women. RESULTS: Women reporting a lump had an increased odds of breast cancer compared with asymptomatic women (OR for diagnostic examination = 2.8, 95% CI = 2.3 to 3.4; OR for screening examination = 3.6, 95% CI = 2.6 to 5.0). No other symptoms were associated with breast cancer after controlling for a reported lump. A new lump at a diagnostic examination was significantly predictive of cancer among women with no prior mammograms (OR = 12.2, 95% CI = 2.8 to 53.5); reporting symptoms at 2 successive exams had little effect on breast cancer risk (OR for lump = 1.2, 95% CI = 0.6 to 2.5). CONCLUSIONS: Having a lump is the most predictive symptom of breast cancer whether it is reported at a screening or diagnostic examination or in conjunction with other symptoms.     

Behavioral Health Services use Among Racial and Ethnic Groups: Results from the California Health Interview Survey (CHIS)

Access and utilization of behavioral health services is a public health issue, yet disparities among racial/ethnic groups persist, resulting in fewer access points and lower utilization. Using pooled 2015 and 2016 California Health Interview Survey (N?=?42,089) data of diverse adults, this study examines provider access points for behavioral health services use. Latinx (OR?=?0.55, 95% CI, 0.38–0.80), Asian (OR?=?0.32, 95% CI, 0.17–0.59), and first generation (OR?=?0.56, 95% CI, .38-.83) individuals, reported lower odds of accessing specialty care behavioral health services, compared to no services. First generation adults reported lower odds accessing a primary care physician (OR?=?0.66, 95% CI, 0.44–0.98), compared to none. Results advance knowledge of behavioral health services access points among racial, ethnic and immigrant groups, following passage of the California Mental Health Services Act. Findings suggest primary care may be an important entry point for behavioral health service use engagement among underserved populations.

     

Is there a menopausal syndrome? Menopausal status and symptoms across racial/ethnic groups

In recent years, research on menopausal symptomalogy has focused on identifying symptom groupings experienced by women as they progress from premenopausal to postmenopausal status. However, most of these studies have been conducted among Caucasian women from western cultures. This leaves open the question of whether the findings from these studies can be extended to women of other racial/ethnic groups or cultures. Furthermore, many of the previous studies have been conducted on relatively small samples. This paper addresses the diversity of the menopause experience by comparing symptom reporting in a large cross-sectional survey of women aged 40-55 years among racial/ethnic groups of women in the United States (Caucasian, African-American, Chinese, Japanese, and Hispanic). Evaluation of the extent to which symptoms group together and consistently relate to menopausal status across these five samples provides evidence for or against a universal menopausal syndrome. The specific research questions addressed in this paper are: (1) How does the factor structure of symptoms among mid-aged women compare across racial/ethnic groups? (2) Is symptom reporting related to race/ethnicity or menopausal status? and (3) Does the relation between menopausal status and symptoms vary across racial/ethnic groups? Analyses are based on 14,906 women who participated in the multi-ethnic, multi-race, multi-site study of mid-aged women called the Study of Women's Health Across the Nation (SWAN). Study participants completed a 15-min telephone or in-person interview that contained questions on a variety of health-related topics. Items of interest for these analyses include symptoms, menstrual history (to assess menopausal status), health status, and sociodemographics. Factor analysis results showed that across all five racial/ethnic groups, two consistent factors emerged; one consisting of clearly menopausal symptoms -- hot flashes and night sweats -- and the other consisting of psychological and psychosomatic symptoms. Results of regression analyses showed racial/ethnic differences in symptom reporting, as well as differences by menopausal status. Controlling for age, education, health, and economic strain, Caucasian women reported significantly more psychosomatic symptoms than other racial/ethnic groups. African-American women reported significantly more vasomotor symptoms. Perimenopausal women, hormone users, and women who had a surgical menopause reported significantly more vasomotor symptoms. All of these groups, plus postmenopausal women, reported significantly more vasomotor symptoms than premenopausal women. The pattern of results argues against a universal menopausal syndrome consisting of a variety of vasomotor and psychological symptoms.     

The Associations between Metalloestrogens,GSTP1, and SLC11A2 Polymorphism and the Risk of Endometrial Cancer

Background: The incidence of endometrial cancer (EC) is still rising. Numerous risk factors including patient characteristics and molecular instability have been identified for EC. The presence of specific molecular markers allows specific diagnostic and prognostic approaches. Several single nucleotide polymorphisms (SNPs) have been identified to influence endometrial cancer risk. Metalloestrogens are metal ions which can mimic estrogen activity; however, their role in uterine pathologies remains unknown. This study aimed to investigate total blood trace elements levels and evaluate the distribution of selected genotypes in GSTP1 and SLC11A2 genes. Methods: This retrospective case-control analysis was carried out in peripheral blood samples of 110 women with endometrial cancer (EC; n = 21), uterine fibroma (n = 25), endometrial polyp (n = 48), and normal endometrium (n = 16). Analysis included measurement of metals and phosphor in serum, and of genetic polymorphisms in GST (rs1695) and SLC11A2 (rs224589) in DNA from white blood cells. Serum trace elements were measured using ICP-OES spectrometry. SNPs were identified using Taq Man real-time PCR genotyping assays. Results: The study confirmed higher age (OR 2.19, 95% CI 1.69–2.24), post-menopausal status (OR 1.89, 95% CI 1.36–1.94), and diabetes type 2 (OR 1.54; 95% CI 0.97–1.72) as independent risk factors for EC. We also found a high level of Cd (OR 1.49; 95% CI 1.31–1.63) and a low level of Co (OR 0.76; 95% CI 0.53–0.59) to be independent risk factors of EC. None of the tested polymorphisms of GSTP1 and SLC11A2 were associated with EC risk. However, high Cd (OR 1.21, 95% CI 1.15–1.29) and Ni (OR 1.07, 95% CI 1.05–1.18) serum levels were significantly associated with a SLC1A2 TG genotype, and high Cd levels with GSTP1 (OR 1.05, 95% CI 1.01–1.13).     

Neighborhood- and individual-level socioeconomic variation in perceptions of racial discrimination

Objective. In approaching the study of racial discrimination and health, the neighborhood- and individual-level antecedents of perceived discrimination need further exploration. We investigated the relationship between neighborhood- and individual-level socioeconomic position (SEP), neighborhood racial composition, and perceived racial discrimination in a cohort of African-American and White women age 40–79 from Connecticut, USA.

Design. The logistic regression analysis included 1249 women (39% African-American and 61% White). Neighborhood-level SEP and racial composition were determined using 1990 census tract information. Individual-level SEP indicators included income, education, and occupation. Perceived racial discrimination was measured as lifetime experience in seven situations.

Results. For African-American women, living in the most disadvantaged neighborhoods was associated with fewer reports of racial discrimination (odds ratio (OR) 0.44; 95% confidence interval (CI) 0.26, 0.75), with results attenuated after adjustment for individual-level SEP (OR 0.54, CI: 0.29, 1.03), and additional adjustment for neighborhood racial composition (OR 0.70, CI: 0.30, 1.63). African-American women with 12 years of education or less were less likely to report racial discrimination, compared with women with more than 12 years of education (OR 0.57, CI: 0.33, 0.98 (12 years); OR 0.51, CI: 0.26, 0.99 (less than 12 years)) in the fully adjusted model. For White women, neither neighborhood-level SEP nor individual-level SEP was associated with perceived racial discrimination.

Conclusion. Individual- and neighborhood-level SEP may be important in understanding how racial discrimination is perceived, reported, processed, and how it may influence health. In order to fully assess the role of racism in future studies, inclusion of additional dimensions of discrimination may be warranted.     

Maternal Birthplace is Associated with Low Birth Weight Within Racial/Ethnic Groups

Introduction While disparities in low birth weight (LBW) incidence by racial/ethnic group are well known, differences in LBW incidence by maternal birthplace within racial/ethnic groups, and particularly, differences after adjustment for pregnancy complications, are less clear. Methods We conducted a population-based study of LBW using 113,760 singleton, live birth records from King County, Washington (2008–2012), a region in the Pacific Northwest with a large immigrant population. Study participants were Asian, non-Hispanic black, Hispanic, Native Hawaiian/Other Pacific Islander (NHOPI), and non-Hispanic white women. Using multivariable logistic regression models, we calculated odds ratios (ORs) and 95% confidence intervals (CIs) to estimate relative risk of LBW (<2500 g) related to maternal race/ethnicity and birthplace (defined by the Millennium Development Goals Regional Groupings). Results Compared with non-Hispanic white women, non-Hispanic black, Asian Indian, Filipino, Japanese, and Vietnamese women had 1.57–2.23-fold higher, statistically significant, risk of having a LBW infant, and NHOPI and Mexican women had 1.30–1.33-fold, statistically significant, higher risk. LBW risk was lower for Asian women from Eastern Asia (OR 0.68, 95% CI 0.55–0.85), non-Hispanic black women from Sub-Saharan Africa (OR 0.58, 95% CI 0.47–0.73), and non-Hispanic white women from other developed countries (OR 0.83, 95% CI 0.69–1.00), as compared with their US-born racial/ethnic counterparts. Results were, in general, similar after adjustment for pregnancy complications. Conclusions Compared with most other racial/ethnic groups, non-Hispanic whites had lower risk of LBW. Foreign-born women had lower risk of LBW compared with their US-born counterparts in the majority of racial/ethnic groups. Pregnancy complications had minimal effect on the associations.     

Assessment of Nutritional Status and Nutrition Impact Symptoms in Patients Undergoing Resection for Upper Gastrointestinal Cancer: Results from the Multi-Centre NOURISH Point Prevalence Study

Background: Identification and treatment of malnutrition are essential in upper gastrointestinal (UGI) cancer. However, there is limited understanding of the nutritional status of UGI cancer patients at the time of curative surgery. This prospective point prevalence study involving 27 Australian tertiary hospitals investigated nutritional status at the time of curative UGI cancer resection, as well as presence of preoperative nutrition impact symptoms, and associations with length of stay (LOS) and surgical complications. Methods: Subjective global assessment, hand grip strength (HGS) and weight were performed within 7 days of admission. Data on preoperative weight changes, nutrition impact symptoms, and dietary intake were collected using a purpose-built data collection tool. Surgical LOS and complications were also recorded. Multivariate regression models were developed for nutritional status, unintentional weight loss, LOS and complications. Results: This study included 200 patients undergoing oesophageal, gastric and pancreatic surgery. Malnutrition prevalence was 42% (95% confidence interval (CI) 35%, 49%), 49% lost ≥5% weight in 6 months, and 47% of those who completed HGS assessment had low muscle strength with no differences between surgical procedures (p = 0.864, p = 0.943, p = 0.075, respectively). The overall prevalence of reporting at least one preoperative nutrition impact symptom was 55%, with poor appetite (37%) and early satiety (23%) the most frequently reported. Age (odds ratio (OR) 4.1, 95% CI 1.5, 11.5, p = 0.008), unintentional weight loss of ≥5% in 6 months (OR 28.7, 95% CI 10.5, 78.6, p < 0.001), vomiting (OR 17.1, 95% CI 1.4, 207.8, 0.025), reduced food intake lasting 2–4 weeks (OR 7.4, 95% CI 1.3, 43.5, p = 0.026) and ≥1 month (OR 7.7, 95% CI 2.7, 22.0, p < 0.001) were independently associated with preoperative malnutrition. Factors independently associated with unintentional weight loss were poor appetite (OR 3.7, 95% CI 1.6, 8.4, p = 0.002) and degree of solid food reduction of <75% (OR 3.3, 95% CI 1.2, 9.2, p = 0.02) and <50% (OR 4.9, 95% CI 1.5, 15.6, p = 0.008) of usual intake. Malnutrition (regression coefficient 3.6, 95% CI 0.1, 7.2, p = 0.048) and unintentional weight loss (regression coefficient 4.1, 95% CI 0.5, 7.6, p = 0.026) were independently associated with LOS, but no associations were found for complications. Conclusions: Despite increasing recognition of the importance of preoperative nutritional intervention, a high proportion of patients present with malnutrition or clinically significant weight loss, which are associated with increased LOS. Factors associated with malnutrition and weight loss should be incorporated into routine preoperative screening. Further investigation is required of current practice for dietetics interventions received prior to UGI surgery and if this mitigates the impact on clinical outcomes.     

Ongoing transmission of hepatitis B virus infection among inmates at a state correctional facility

OBJECTIVES: We sought to determine hepatitis B virus (HBV) infection prevalence, associated exposures, and incidence among male inmates at a state correctional facility. METHODS: A cross-sectional serological survey was conducted in June 2000, and susceptible inmates were retested in June 2001. RESULTS: At baseline, 230 inmates (20.5%; 95% confidence interval [CI]=18.2%, 22.9%) exhibited evidence of HBV infection, including 11 acute and 11 chronic infections. Inmates with HBV infection were more likely than susceptible inmates to have injected drugs (38.8% vs 18.0%; adjusted prevalence odds ratio [OR]=3.0; 95% CI=1.9, 4.9), to have had more than 25 female sex partners (27.7% vs 17.5%; adjusted prevalence OR=2.0; 95% CI=1.4, 3.0), and to have been incarcerated for more than 14 years (38.4% vs 17.6%; adjusted prevalence OR=1.7; 95% CI=1.1, 2.6). One year later, 18 (3.6%) showed evidence of new HBV infection. Among 19 individuals with infections, molecular analysis identified 2 clusters involving 10 inmates, each with a unique HBV sequence. CONCLUSIONS: We documented ongoing HBV transmission at a state correctional facility. Similar transmission may occur at other US correctional facilities and could be prevented by vaccination of inmates.     

Risk of fracture and pneumonia from acid suppressive drugs

A recently published systematic review and meta-analysis, incorporating all relevant studies on the association of acid suppressive medications and pneumonia identified up to August 2009, revealed that for every 200 patients, treated with acid suppressive medication, one will develop pneumonia. They showed the overall risk of pneumonia was higher among people using proton pump inhibitors (PPIs) [adjusted odds ratio (OR) = 1.27, 95% CI: 1.11-1.46, I² = 90.5%] and Histamine_-2 receptor antagonists (H₂RAs) (adjusted OR = 1.22, 95% CI: 1.09-1.36, I² = 0.0%). In the randomized controlled trials, use of H₂RAs was associated with an elevated risk of hospital-acquired pneumonia (relative risk 1.22, 95% CI: 1.01-1.48, I² = 30.6%). Another meta-analysis of 11 studies published between 1997 and 2011 found that PPIs, which reduce stomach acid production, were associated with increased risk of fracture. The pooled OR for fracture was 1.29 (95% CI: 1.18-1.41) with use of PPIs and 1.10 (95% CI: 0.99-1.23) with use of H₂RAs, when compared with non-use of the respective medications. Long-term use of PPIs increased the risk of any fracture (adjusted OR = 1.30, 95% CI: 1.15-1.48) and of hip fracture risk (adjusted OR = 1.34, 95% CI: 1.09-1.66), whereas long-term H₂RA use was not significantly associated with fracture risk. Clinicians should carefully consider when deciding to prescribe acid-suppressive drugs, especially for patients who are already at risk for pneumonia and fracture. Since it is unnecessary to achieve an achlorhydric state in order to resolve symptoms, we recommend using the only minimum effective dose of drug required to achieve the desired therapeutic goals.
