Disparities in the prevalence of comorbidities among US adults by state Medicaid expansion status

IntroductionAbout 92% of US older adults have at least one chronic disease or medical condition and 77% have at least two. Low-income and uninsured adults in particular experience a higher burden of comorbidities, and the Medicaid expansion provision of the Affordable Care Act was designed to improve access to healthcare in this population group. However, a significant number of US states have declined expansion. The purpose of this study is to determine the distribution of low-income and uninsured adults in expanded versus non-expanded states, and evaluate the prevalence of comorbidities in both groups.MethodsData from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) dataset was analyzed, and Medicaid expansion status was assessed from the Center for Medicare and Medicaid Services report on State Medicaid and CHIP Income Eligibility Standards. Next, age adjusted mean number of comorbidities between expanded and non-expanded states was compared, with adjustment for socio-demographic differences.ResultsExpanded states had a higher proportion of adults with income of at least $50,000 per year (39.6% vs. 35.5%, p < 0.01) and a lower proportion of individuals with no health insurance coverage (15.2% vs. 20.3%, p < 0.01) compared with non-expanded states. Among the uninsured, there was a higher proportion of obese (31.6% vs. 26.9%, p < 001), and higher average number of comorbidities (1.62 vs. 1.52, p < 0.01) in non-expanded states compared to expanded states. Overall, the prevalence of comorbidities was higher among BRFSS participants in states that did not expand Medicaid compared with those in expanded states.ConclusionStates without Medicaid expansion have a greater proportion of poor, uninsured adults with more chronic diseases and conditions.     

Impact of the 13-valent pneumococcal conjugate vaccine on Streptococcus pneumoniae multiple serotype carriage

IntroductionPneumococcal multiple serotype carriage is important for evolution of the species and to understand how the pneumococcal population is changing with vaccination. We aimed to determine the impact of the 13-valent pneumococcal conjugate vaccine (PCV13) on multiple serotype carriage.Methods and materialsNasopharyngeal samples from fully vaccinated pneumococcal carriers (4 doses of PCV13, n = 141, aged 18–72 months) or from non-vaccinated pneumococcal carriers (0 doses of any PCV, n = 140, same age group) were analyzed. Multiple serotype carriage was evaluated by DNA hybridization with a molecular serotyping microarray that detects all known serotypes.ResultsVaccinated children had a lower prevalence of multiple serotype carriage than the non-vaccinated group (20.6% vs 29.3%, p = 0.097), and a significantly lower proportion of PCV13 serotypes (6.4% vs 38.5%, p = 0.0001). PCV13 serotypes found among vaccinated children were mostly detected as a minor serotype in co-colonization with a more abundant non-vaccine serotype. Vaccinated children were colonized by a significantly higher proportion of commensal non-pneumococcal Streptococcus spp. (58.2% vs 42.8%, p = 0.012). In vaccinated children there were significantly less non-vaccine type (NVT) co-colonization events than expected based on the distribution of these serotypes in non-vaccinated children.ConclusionsThe results suggest that vaccinated children have lower pneumococcal multiple serotype carriage prevalence due to higher competitive abilities of non-vaccine serotypes expanding after PCV13 use. This might represent an additional benefit of PCV13, as decreased co-colonization rates translate into decreased opportunities for horizontal gene transfer and might have implications for the evolution and virulence of pneumococci.     

Tocilizumab therapy reduced intensive care unit admissions and/or mortality in COVID-19 patients

IntroductionNo therapy has yet proven effective in COVID-19. Tocilizumab (TCZ) in patients with severe COVID-19 could be an effective treatment.MethodWe conducted a retrospective case-control study in the Nord Franche-Comté Hospital, France. We compared the outcome of patients treated with TCZ and patients without TCZ considering a combined primary endpoint: death and/or ICU admissions.ResultsPatients with TCZ (n = 20) had a higher Charlson comorbidity index (5.3 [±2.4] vs 3.4 [±2.6], P = 0.014), presented with more severe forms (higher level of oxygen therapy at 13 L/min vs 6 L/min, P < 0.001), and had poorer biological findings (severe lymphopenia: 676/mm³ vs 914/mm³, P = 0.037 and higher CRP level: 158 mg/L vs 105 mg/L, P = 0.017) than patients without TCZ (n = 25). However, death and/or ICU admissions were higher in patients without TCZ than in the TCZ group (72% vs 25%, P = 0.002).ConclusionDespite the small sample size and retrospective nature of the work, this result strongly suggests that TCZ may reduce the number of ICU admissions and/or mortality in patients with severe SARS-CoV-2 pneumonia.     

BLISS index using WOMAC index detects between-group differences at low-intensity symptom states in osteoarthritis

ObjectivesThe ability of the Bellamy et al. Low-Intensity Symptom State-attainment (BLISS) Index to differentiate between treatment groups (hylan G-F 20 vs. appropriate care) at low and very low levels of state attainment in patients with knee osteoarthritis was explored using the stiffness, function, and total index (TI) components of the WOMAC.Study Design and SettingSix different BLISS measures were analyzed using five WOMAC score thresholds: ≤5 normalized units (NUs): ≤10, ≤15, ≤20, and ≤25 (lower = better health).ResultsMore patients in the hylan G-F 20 group achieved BLISS states in all three WOMAC subscales for all six BLISS analyses. These differences were statistically significant for the BLISS response at any time at all threshold levels except ≤5 NU.ConclusionsThe six BLISS measures and threshold levels of stiffness, function, and TI score were able to statistically discriminate between treatment groups. BLISS-10 is a therapeutically attainable very low symptom state at which clinically important statistically significant between-group differences are detectable in pain, stiffness, function, and TI score and therefore may provide a benchmark against which therapeutic interventions can be assessed. However, the value to patients of these symptom states requires further elaboration.     

Determinants of patient satisfaction regarding pain care

BackgroundThe management of pain in hospitalized patients remains a major public hospital priority. It has been the object of three French national programs since 1999. The purpose of this study was to reassess pain prevalence, pain intensity and patient perception of its management ten years after the first national program and to determine the factors related to the patient satisfaction with efforts to decrease pain intensity.MethodsA 1-day cross-sectional survey in a university hospital.ResultsPain prevalence was 59%. Pain intensity varied according to the medical department with lower intensity in surgery and obstetrics than medicine departments. Eighty-one percent of patients were satisfied with their pain management. Patient satisfaction was higher when doctors and nurses were heavily involved in the process of pain relief (OR = 6.6; 95% CI 3.8, 11.4), and when their pain had decreased (OR = 2.9; 1.7, 5.0). The magnitude of decrease in pain were higher when the medical team was involved (OR = 1.9; 95% IC 1.1, 3.3) and pain intensity was measured (OR = 1.6; 1.0, 2.4). Perceptions of doctor and nurse involvement in the patient's care was higher when pain intensity was measured (OR = 6.0; 3.4, 10.5), an immediate treatment offered (OR = 3.5; 2.0, 6.2), encouragement to ask for an analgesic was provided (OR = 2.0; 1.1, 3.5) and for patients with acute pain (OR = 2.2; 1.0, 4.7).ConclusionsThis study identifies the factors related to patient satisfaction with pain management and the magnitude of the decrease in pain which should allow further efforts to improve the management of pain and reduce its intensity in hospital inpatients.     

Impacts of the Affordable Care Act on Receipt of Women's Preventive Services in Community Health Centers in Medicaid Expansion and Nonexpansion States

BackgroundThe Affordable Care Act (ACA) increased health insurance coverage throughout the United States and improved care delivery for some services. We assess whether ACA implementation and Medicaid expansion were followed by greater receipt of recommended preventive services among women and girls in a large network of community health centers.MethodsUsing electronic health record data from 354 community health centers in 14 states (10 expansion, 4 nonexpansion), we used generalized estimating equations and difference-in-difference methods to compare receipt of six recommended preventive services (cervical cancer screening, human papilloma virus vaccination, chlamydia screening, influenza vaccination, human immunodeficiency virus screening, and blood pressure screening) among active female patients ages 11 to 65 (N = 711,121) before and after ACA implementation and between states that expanded versus did not expand Medicaid.ResultsExcept for blood pressure screening, receipt of all examined preventive services increased after ACA implementation in both Medicaid expansion and nonexpansion states. Influenza vaccination and blood pressure screening increased more in expansion states (adjusted absolute prevalence difference-in-difference, 1.55; 95% confidence interval, 0.51–2.60; and 1.98; 95% confidence interval, 0.91–3.05, respectively). Chlamydia screening increased more in nonexpansion states (adjusted absolute prevalence difference-in-difference: ?4.21; 95% confidence interval, ?6.98 to ?1.45). Increases in cervical cancer screening, human immunodeficiency virus screening, and human papilloma virus vaccination did not differ significantly between expansion and nonexpansion states.ConclusionsAmong female patients at community health centers, receipt of recommended preventive care improved after ACA implementation in both Medicaid expansion and nonexpansion states, although the overall rates remained low. Continued support is needed to overcome barriers to preventive care in this population.     

Trends in reasons for non-receipt of influenza vaccination during pregnancy in Georgia, 2004–2011

BackgroundConsiderable research has identified barriers to antenatal influenza vaccination, yet no research has explored temporal trends in reasons for non-receipt.PurposeTo examine trends in reasons for non-receipt of influenza vaccination during pregnancy.MethodsSerial cross-sectional analyses using 8 years of Georgia Pregnancy Risk Assessment Monitoring Survey (PRAMS) data were conducted. Weighted logistic regression was used to examine trends in the prevalence of citing reasons for non-receipt over time.ResultsBetween 2004 and 2011, 8300 women reported no influenza vaccination during or immediately before pregnancy. Proportions of women citing “doctor didn’t mention vaccination,” “in first trimester during influenza season,” and “not pregnant during influenza season” decreased significantly over time (Doctor didn’t mention: 48.0% vs. 27.1%, test for trend p < 0.001; in first trimester: 26.8% vs. 16.3%, test for trend p < 0.001; not influenza season: 24.2% vs. 12.7%, test for trend p = 0.001). Safety concerns increased over 2004 proportions in 2010 (concern about side effects for me: 40.2% vs. 28.5%, prevalence ratio (PR): 1.41, 95% confidence interval (CI): 1.16, 1.71; concern about harming my baby: 38.9% vs. 31.0%, PR = 1.26, 95% CI: 1.04, 1.53) and 2011 (concern about side effects for me: 39.0% vs. 28.5%, PR = 1.37, 95% CI: 1.13, 1.65; concern about harming my baby: 38.8% vs. 31.0%, PR = 1.25, 95% CI: 1.04, 1.50). Following the 2009/2010 H1N1 pandemic, more Hispanic women cited concern about vaccination harming their baby than other women; in 2011, their concern remained elevated relative to non-Hispanic white women (63% vs. 35%; adjusted PR = 1.79, 95% CI: 1.23, 2.61).ConclusionExamining trends in reasons for non-receipt of antenatal influenza vaccination can reflect successes related to vaccine promotion and areas for improvement. By highlighting differential impacts of the 2009/2010 H1N1 pandemic, we reveal opportunities for additional research on tailoring vaccine promotion efforts to specific types of women.     

Overweight and obesity in Eastern Morocco: Prevalence and associated risk factors among high school students

BackgroundOverweight and obesity in children and adolescents have become a major public health problem affecting most countries worldwide. The purpose of the study was to assess the prevalence and risk factors of overweight and obesity among public high school students in Eastern Morocco.MethodsA cross-sectional survey was conducted between February and May 2014 among a sample of 2271 students (1086 girls and 1185 boys). References from the International Obesity Task Force (IOTF) were used to determine the prevalence of overweight and obesity.ResultsThe prevalence of overweight and obesity reached 12.2% (14.2% in girls vs 10.4% in boys, P < 0.01) and 3.0% (3.1% in girls vs 2.8% in boys), respectively. Risk factors associated with overweight and obesity were urban residence (OR = 1.76; [1.18–2.63]; P < 0.01), father's income ≥ 5000 MAD (OR = 1.32; [1.02–1.70]; P < 0.05), father's overweight (including obesity) (OR = 1.87; [1.38–2.54]; P < 0.001) and female sex (OR = 1.31; [1.02–1.68]; P < 0.05).ConclusionThe prevalence of overweight/obesity has reached an alarming rate among high school students in the Eastern region of Morocco. The findings of the present study suggest an urgent need to set up a strategy to prevent and combat this epidemic.     

The MTHFR C677T mutation is not a risk factor recognized for HBV-related HCC in a population with a high prevalence of this genetic marker

BackgroundPolymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene can affect disease progression in HBV infection. However, the results from different reports are inconsistent. The aim of this study was to investigate the association between the MTHFR C677T polymorphism and the outcome of HBV infection in a Tianjin Han population.MethodsTaqMan SNP genotyping was employed to determine the alleles and genotypes of MTHFR C677T in 2511 subjects from various stages of HBV infection and 549 healthy controls.ResultsOf the 3060 subjects, the genotypic frequencies were CT 48.9%, TT 29.3% and CC 21.8%; the allelic frequencies were T 53.8% and C 46.2%. There was no significant difference in genotypic or allelic distribution among the different disease groups. When either healthy subjects or self-limited subjects were used as controls, the TT genotype and the T allele conferred protective effects against hepatocellular carcinoma (HCC) (HCC vs healthy subjects: OR = 0.588, 95% CI = 0.413–0.836, P = 0.003; OR = 0.768, 95% CI = 0.645–0.915, P = 0.003, respectively. HCC vs self-limited subjects: OR = 0.598, 95% CI = 0.404–0.886, P = 0.010; OR = 0.772, 95% CI = 0.635–0.940, P = 0.010, respectively). After sub-stratification by gender, the prevalence of the TT genotype or T allele was the lowest in the male HCC group (TT 23.5%, T 49.8%). The protective effects of the TT genotype and the T allele were observed in male HCC and cirrhotic subjects (HCC vs self-limited subjects: OR = 0.470, 95% CI = 0.288–0.766, P = 0.002; OR = 0.681, 95% CI = 0.535–0.866, P = 0.002, respectively. Liver cirrhosis vs self-limited subjects: OR = 0.624, 95% CI = 0.392–0.992, P = 0.046; OR = 0.791, 95% CI = 0.627–0.998, P = 0.048, respectively), but not in female. When the subjects were stratified according to the clinical features, no statistically significant difference in the genotypic distribution was observed (P > 0.05).ConclusionsThe TT genotype and T allele of MTHFR C677T may confer a protective effect on disease progression to HCC in HBV-infected individuals, especially among male patients, in a population with a high prevalence of this genetic marker.     

Trends in prolonged sitting time among European adults: 27 country analysis

ObjectiveTo examine trends in adult sitting time across 27 European countries.MethodData were from the Eurobarometer surveys collected in 2002, 2005, and 2013. Sitting time data were used to categorise respondents into ‘low’ (0 to 4h30min), ‘middle’ (4h31min to 7h30min), and ‘high’ levels of sitting (>7h30min). We modelled the likelihood of being in the high sitting group within a given country and overall across the three time points, controlling for age, gender, education, employment status, and physical activity.ResultsIn total 17 countries had sitting data at all three time points; among these countries the prevalence of ‘high sitting’ decreased steadily from 23.1% (95% CI = 22.2–24.1) in 2002 to 21.8% (95% CI = 20.8–22.8) in 2005, and 17.8% (95% CI = 16.9–18.7) in 2013. A further 10 countries had data only over the latter two time points; among these countries the prevalence of high sitting decreased from 27.7% (95% CI = 26.0–29.4) in 2005 to 19.0% (95% CI = 17.6–20.5) in 2013.ConclusionTime spent in sedentary behaviour may not be increasing in the European region, and prolonged sitting may, in fact, be decreasing. This finding has important implications for the sedentary behaviour debate and the policy response.     

ABO,Secretor and Lewis histo-blood group systems influence the digestive form of Chagas disease

Chagas disease, caused by Trypanosoma cruzi, can affect the heart, esophagus and colon. The reasons that some patients develop different clinical forms or remain asymptomatic are unclear. It is believed that tissue immunogenetic markers influence the tropism of T. cruzi for different organs. ABO, Secretor and Lewis histo-blood group systems express a variety of tissue carbohydrate antigens that influence the susceptibility or resistance to diseases. This study aimed to examine the association of ABO, secretor and Lewis histo-blood systems with the clinical forms of Chagas disease. We enrolled 339 consecutive adult patients with chronic Chagas disease regardless of gender (cardiomyopathy: n = 154; megaesophagus: n = 119; megacolon: n = 66). The control group was composed by 488 healthy blood donors. IgG anti-T. cruzi antibodies were detected by ELISA. ABO and Lewis phenotypes were defined by standard hemagglutination tests. Secretor (FUT2) and Lewis (FUT3) genotypes, determined by Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), were used to infer the correct histo-blood group antigens expressed in the gastrointestinal tract. The proportions between groups were compared using the χ2 test with Yates correction and Fisher's exact test and the Odds Ratio (OR) and 95% Confidence Interval (95% CI) were calculated. An alpha error of 5% was considered significant with p-values < 0.05 being corrected for multiple comparisons (pc). No statistically significant differences were found for the ABO (X²: 2.635; p-value = 0.451), Secretor (X²: 0.056; p-value = 0.812) or Lewis (X²: 2.092; p-value = 0.351) histo-blood group phenotypes between patients and controls. However, B plus AB Secretor phenotypes were prevalent in pooled data from megaesophagus and megacolon patients (OR: 5.381; 95% CI: 1.230–23.529; p-value = 0.011; pc = 0.022) in comparison to A plus O Secretor phenotypes. The tissue antigen variability resulting from the combined action of ABO and Secretor histo-blood systems is associated with the digestive forms of Chagas disease.     

Important oral care needs of older French people: A cross-sectional study

BackgroundOlder persons comprise a growing proportion of the European population and may have a distinct epidemiological oral profile requiring specific preventive and curative care poorly documented. The objectives of this study were to assess the oral health status of people ≥ 90 years of age in France, to compare their perceived and observed oral care needs and to investigate the oral problems associated with a low oral health-related quality-of-life (OHRQoL).MethodsAn oral cross-sectional study was performed during the 25th follow-up of a cohort of older persons being followed up prospectively for screening of dementia over a 15-year period in Gironde and Dordogne, France. Clinical oral indices were determined by oral examinations conducted at the participants’ place of living. Cohen's Kappa coefficient was used to assess the agreement between perceived and observed oral care needs. Oral problems associated with a low OHRQoL, measured with the Geriatric Oral Health Assessment Index (GOHAI < 50) were investigated with logistic regression. Odds ratios (OR) were estimated with their 95% confidence intervals (CI).ResultsData from 90 persons were analysed (76% female; median age = 93 years; 20% living in an institution). Plaque and calculus were present in 93% and 58% respectively, of the 74 dentate participants. The mean number of decayed, missing, and filled teeth was 26.5 (± 5.3); 66% of the participants had at least one untreated decayed tooth. Among the 85 participants with tooth loss not replaced by a fixed denture, two thirds had a removable dental prosthesis; 84% of these prostheses were considered to be maladapted. Among the 39 participants who felt unable to consult a dentist (43%), lack of transportation was the most frequently cited reason. Although 88% of the participants needed oral care, only 26% perceived that they had such a need (Kappa = 0.06). Oral problems associated with a GOHAI < 50 were the absence of posterior occluding teeth (OR = 7.15; 95%CI = 1.53–33.35; P = 0.012), feeling of dry mouth (OR = 11.94; 95%CI = 3.21–44.39; P = 0.0002) and oral pain (OR = 9.06; 95%CI = 1.91–69.00; P = 0.033).ConclusionsPersons ≥ 90 years of age have considerable preventive and curative dental care needs that impact their quality-of-life but they are rarely aware and lack transportation.

Patterns and predictors of state adult obesity prevention legislation enactment in US states: 2010–2013

ObjectiveThis study examined bill- and state-level factors associated with enactment of adult obesity prevention legislation in US states.MethodsA review of bills in the Rudd Center for Food Policy and Obesity's legislative database identified 487 adult obesity prevention bills, or proposed legislation, introduced between 2010 and 2013. Multilevel models were constructed to examine bill- and state-level characteristics associated with enactment.ResultsFrom 2010 to 2013, 81 (17%) of obesity prevention bills introduced were enacted across 35 states and the District of Columbia. Bills introduced in 2010 were more likely to be enacted than in 2013 (OR = 9.49; 95% CI: 2.61–34.5). Bills focused on access to healthy food, physical activity, general and educational programs, as well as modifying rules and procedures (e.g., preemption) had greater odds of enactment relative to food and beverage taxes (OR = 8.18; 95% CI: 2.85–23.4 healthy food; OR = 17.3; 95% CI: 4.55–65.7 physical activity; OR = 15.2; 95% CI: 4.80–47.9 general; OR = 13.7; 95% CI: 3.07–61.5 rules).ConclusionThe year of bill introduction and overall bill enactment rate were related to adult obesity prevention legislation enactment in states. This study highlights the importance of a bill's topic area for enactment and provides insights for advocates and policymakers trying to address enactment barriers.     

The impact of 10-valent and 13-valent pneumococcal conjugate vaccines on hospitalization for pneumonia in children: A systematic review and meta-analysis

BackgroundThis systematic review and meta-analysis aimed at summarizing available data on the impact of PCV10 and PCV13 in reducing the incidence of CAP hospitalizations in children aged <5 years.MethodsA systematic search of the literature was conducted. We included time-series analyses and before-after studies, reporting the incidence of hospitalization for pneumonia in the periods before and after the introduction of PCV10 or PCV13 into the immunization program. Pooled estimates of Incidence Rate Ratio (IRR) were calculated by using a random-effects meta-analytic model. Results were stratified according to age-groups (<24 months and 24–59 months) and case definitions of pneumonia (clinically and radiologically confirmed pneumonia).ResultsA total of 1533 potentially relevant articles were identified. Of these, 12 articles were included in the analysis. In children aged <24 months, the meta-analysis showed a reduction of 17% (95%CI: 11–22%, p-value < 0.001) an of 31% (95%CI: 26–35%, p-value < 0.001) in the hospitalization rates respectively for clinically and radiologically confirmed pneumonia, respectively, after the introduction of the novel PCVs.In children aged 24–59 months, the meta-analysis showed a reduction of 9% (95%CI: 5–14%, p-value < 0.001) and of 24% (95%CI: 12–33%, p-value < 0.001) in the hospitalization rates for clinically and radiologically confirmed pneumonia, respectively, after the introduction of the novel PCVs.High heterogeneity was detected among studies evaluating the hospitalization rate for clinically and radiologically confirmed pneumonia.ConclusionsThe results of this study revealed a significant impact of PCV10 and PCV13 in reducing the hospitalizations for pneumonia, particularly in children aged <24 months and for radiologically confirmed disease. Further appropriately designed studies, comparing the impact of PCV10 and PCV13, are needed in order to obtain solid data on which to establish future immunization strategies.     

Prevalence of overweight and obesity in China: Results from a cross-sectional study of 441 thousand adults, 2012–2015

ObjectivesObesity has become a global health public problem. The study aims to examine the latest prevalence of overweight and obesity in China.MethodsData came from the China Hypertension Survey (CHS), a nationally representative cross-sectional study among residents aged ≥18 years from October 2012 to December 2015. Overweight and obesity were defined as 25 ≤ BMI < 30 kg/m² and BMI ≥ 30 kg/m² according to the WHO classifications, respectively.ResultsThe data of 441 306 participants were analyzed. The prevalence of overweight and obesity was 28.1% and 5.2% respectively. The prevalence of overweight and obesity varied considerably across provinces. The prevalence of overweight was the highest in Beijing, which was 2.8 fold of the lowest in Guangxi (40.9% vs. 14.6%). The prevalence of obesity was the highest in Tianjin, which was 9.4 fold of the lowest in Hainan (12.2% vs. 1.3%). There was a striking north-south gradient with the prevalence higher in Northeast and Northwest China and lower in Southeast China. Multivariate logistic regression analysis indicated that sex, age, education, smoking, marital status and family history of cardiovascular disease were significantly associated with overweight and obesity.ConclusionsOverweight and obesity are highly prevalent among Chinese adults, and their prevalence varies greatly among different population subgroups and provinces. National and provincial obesity control and prevention strategies should be public health priorities in China.     

Recognizing disordered eating in primary care patients with obesity

ObjectiveIn clinical practice, behavioral approaches to obesity treatment focus heavily on diet and exercise recommendations. However, these approaches may not be effective for patients with disordered eating behaviors. Little is known about the prevalence of disordered eating behaviors in primary care patients with obesity or whether they affect difficulty making dietary changes.MethodsWe conducted a telephone interview of 337 primary care patients aged 18–65 years with BMI ≥ 35 kg/m² in Greater Boston, 2009–2011 (58% response rate, 69% women). We administered the Three-Factor Eating Questionnaire R-18 (scores 0–100) and the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) (scores 0–100). We measured difficulty making dietary changes using four questions regarding perceived difficulty changing diet (Scores 0–10).Results50% of the patients reported high emotional eating (score > 50) and 28% reported high uncontrolled eating (score > 50). Women were more likely to report emotional [OR = 4.14 (2.90, 5.92)] and uncontrolled eating [OR = 2.11 (1.44, 3.08)] than men. African-Americans were less likely than Caucasians to report emotional [OR = 0.29 (95% CI: 0.19, 0.44)] and uncontrolled eating [OR = 0.11 (0.07, 0.19)]. For every 10-point reduction in QOL score (IWQOL-lite), emotional and uncontrolled eating scores rose significantly by 7.82 and 5.48, respectively. Furthermore, participants who reported emotional and uncontrolled eating reported greater difficulty making dietary changes.SummaryDisordered eating behaviors are prevalent among obese primary care patients and disproportionately affect women, Caucasians, and patients with poor QOL. These eating behaviors may impair patients' ability to make clinically recommended dietary changes. Clinicians should consider screening for disordered eating behaviors and tailoring obesity treatment accordingly.     

Smoking dependence in 18 European countries: Hard to maintain the hardening hypothesis

ObjectiveWhen the prevalence of smoking decreases in a population, there is a hypothesis—the so-called “hardening hypothesis”—that the remaining smokers form a subgroup of “hardcore smokers.” Our aims were to test the hardening hypothesis and to analyze the determinants of high dependence taking into account both individual and country-level characteristics.MethodWithin the Pricing Policies and Control of Tobacco in Europe (PPACTE) project, we conducted a face-to-face survey on smoking between January and July 2010 in 18 European countries, including 2882 male and 2254 female smokers with complete information on smoking dependence. The Heaviness of Smoking Index (HSI) was used as a measure of tobacco dependence. We correlated smoking prevalence and dependence using the country as unit of analysis. Moreover, we fitted multilevel logistic regression models.ResultsCountry-specific prevalence of smoking was positively, although not significantly, correlated with the proportion of highly tobacco-dependent smokers (overall r_sp = 0.203, p = 0.419), both in men (r_sp = 0.235, p = 0.347) and women (r_sp = 0.455, p = 0.058). Using individual-level analysis, high dependence was positively related to age, and, although not significantly, to smoking prevalence, and inversely related to level of education. The lack of a smoking ban at home was positively related to smoking dependence.ConclusionsUsing both ecological and individual-level analyses, the relations between smoking prevalence and HSI were not significant, but in the opposite direction as compared to that assumed by the “hardening hypothesis.” Therefore, our data provide empirical evidence against this theory, thus supporting the feasibility of an endgame strategy.     

Decreased accuracy in interpretation of community-based screening mammography for women with multiple clinical risk factors

ObjectiveTo assess the impact of women's breast cancer risk factors (use of hormone therapy, family history of breast cancer, previous breast biopsy) on radiologists' mammographic interpretive performance and whether the influence of risk factors varies according to radiologist characteristics.Study Design and SettingScreening mammograms (n = 638,947) performed from 1996 to 2005 by 134 radiologists from three Breast Cancer Surveillance Consortium registries was linked to cancer outcomes, radiologist surveys, and patient questionnaires. Interpretive performance measures were modeled using marginal and conditional logistic regression.ResultsHaving one or more clinical risk factors was associated with higher recall rates (1 vs. 0 risk factors: odds ratio [OR] = 1.17, 95% confidence interval [CI] = 1.15–1.19; ≥2 vs. 0: OR = 1.43, 95% CI = 1.40–1.47) and lower specificity (1 vs. 0: OR = 0.86 [95% CI = 0.84–0.88]; ≥2 vs. 0: OR = 0.70 [95% CI = 0.68–0.72]) without a corresponding improvement in sensitivity and only a small increase in positive predictive value (1 vs. 0: OR = 1.08 [95% CI = 0.99–1.19]; ≥2 vs. 0: OR = 1.12 [95% CI = 0.99–1.26]). There was no indication that influence of risk factors varied by radiologist characteristics.ConclusionWomen with clinical risk factors who undergo screening mammography are more likely recalled for false-positive evaluation without an associated increase in cancer detection. Radiologists and patients with risk factors should be aware of this increased risk of adverse screening events.
