Facteurs sociodémographiques et recours aux soins pour raisons psychologiques chez les jeunes adultes

BackgroundAlthough young adults exhibit a high rate of psychiatric disorders, their rate of access to mental health care is low compared with older age groups. Our study examined the relationship between socio-demographic factors and the use of health care services for psychological reasons.MethodsWe studied a community sample of 1103 French 22 to 35-year-old (TEMPO cohort study) who were surveyed by mailed questionnaire in 2009. Data were collected regarding participants’ health (internalizing and externalizing psychological symptoms in 1991 and 2009), health care use (access to health professionals and psychotropic medications in case of psychological difficulties), and socio-demographic factors (sex, age, employment status, marital situation, social support). Parental history of depression was ascertained based on TEMPO participants’ and their parents’ reports (in the GAZEL cohort study).ResultsIn the 12 months preceding the study, 16.7% of study participants saw a health professional and 12.8% took a psychotropic medication for psychological reasons. In multivariate regression, models adjusted for all socio-demographic and psychological characteristics, access to health professionals was associated with being unemployed/out of the labor force (OR = 1.93; 95% CI = 1.11–3.30), family situation (OR in participants living with a partner with no children: 2.16; 95% CI 1.26–3.72; OR in participants not living with a partner: 2.29; 95% CI = 1.34–3.90), and having low social support (OR = 1.75; 95% CI = 1.21–2.54). The use of psychotropic medications was associated with female gender (OR = 2.70; 95% CI = 1.60–4.55), being unemployed/out of the labor force (OR = 3.85; 95% CI = 2.14–6.95), not living with a partner (OR = 2.04; 95% CI = 1.09–3.80) and having low social support (OR = 1.65; 95% CI = 1.05–2.59). Additionally, use of health services was associated with participants’ and their parents’ psychological difficulties.     

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.     

Correlates between risk perceptions of cervical cancer and screening practice

ObjectivesTo identify the correlates between risk perceptions and cervical cancer screening among urban Malaysian women.MethodA cross-sectional household survey was conducted among 231 women in Petaling Jaya city in 2007. The association of risk perceptions of cervical cancer and screening practice was analyzed using Poisson regression.Results56% of the respondents ever had a Pap smear test. Knowledge of signs and symptoms (aPR = 1.11, 95% CI = 1.03–1.19), age (aPR = 1.02, 95% CI = 1.01–1.03), number of pregnancies (aPR = 1.06, 95% CI = 1.01–1.11), marital status, education level and religion were found to be significant correlates of Pap smear screening. Respondents who were never married were less likely to have had a Pap smear. Those who had no education or primary education were less likely to have had a Pap smear compared to those with degree qualification. The prevalence of screening was significantly higher among Christians and others (aPR = 1.35; 95% CI = 1.01–1.81) and Buddhists (aPR = 1.38; 95% CI = 1.03–1.84), compared to Muslims.ConclusionEliminating anecdotal beliefs as risks via targeted knowledge on established risk factors and culturally sensitive screening processes are strategic for increasing and sustaining uptake of Pap smear screening versus current opportunistic screening practices.     

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.     

Ischemic stroke in Morocco: Prehospital delay and associated factors

ObjectivesThis study aimed to estimate prehospital delay and to identify the factors associated with the late arrival of patients with ischemic stroke at the Souss Massa Regional Hospital Center in Morocco.Patients and methodsAn observational, prospective, cross-sectional study was conducted from March 2019 to September 2019 in the Souss Massa regional hospital center, which is a public hospital structure. A questionnaire was administered to patients with ischemic stroke and to bystanders (family or others), while clinical and paraclinical data were collected from medical records. Univariate and multivariate logistic regression analyses were used to identify the factors associated with delayed arrival at emergency department.ResultsA total of 197 patients and 197 bystanders who fulfilled the criteria for the study were included. The median time from symptom onset to hospital arrival was 6 hours (IQR, 4–16). Multiple regression analysis showed that illiteracy (OR 38.58; CI_95%: 3.40–437.27), waiting for symptoms to disappear (patient behavior) (OR 11.24; CI_95%: 1.57–80.45), deciding to go directly to the hospital (patient behavior) (OR 0.07; CI_95%: 0.01–0.57), bystander's knowledge that stroke is a disease requiring urgent care within a limited therapeutic window (OR 0.005; CI_95%: 0.00–0.36), and direct admission without reference (OR 0.005; CI_95%: 0.00–0.07), were independently associated with late arrival (> 4.5 hours) of patients with acute ischemic stroke. In addition, illiteracy (OR 24.62; CI_95%: 4.37–138.69), vertigo and disturbance of balance or coordination (OR 0.14; CI_95%: 0.03–0.73), the relative's knowledge that stroke is a disease requiring urgent care and within a limited therapeutic window (OR 0.03; CI_95%: 0.00–0.22), calling for an ambulance (relative's behavior) (OR 0.16; CI_95%: 0.03–0.80), distance between 50 and 100 km (OR 10.16; CI_95%: 1.16–89.33), and direct admission without reference (OR 0.03; CI_95%: 0.00–0.14), were independently associated with late arrival (> 6 hours) of patients with acute ischemic stroke.ConclusionPatient behavior, bystander knowledge and direct admission to the competent hospital for stroke care are modifiable factors potentially useful for reducing onset-to-door time, and thereby increasing the implementation rates of acute stroke therapies.     

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.     

Évolution du statut nutritionnel d’une cohorte d’enfants tunisiens au cours de l’hospitalisation : facteurs de risque de la dénutrition hospitalière

ObjectivesStudy the evolution of the nutritional status of a cohort of hospitalized children and identify the risk factors of hospital malnutrition.MethodsProspective, cross-sectional study carried out in a pediatric department over a period of six months, including all children aged ≥ 30 days, hospitalized for a period ≥ six days. Anthropometric data were assessed on admission and discharge. Food consumption was assessed using the flower tool. We identified the risk factors for hospital undernutrition (HUN) by multivariate analysis.ResultsWe included 120 patients with a mean age 46.3 months. The prevalence of acute undernutrition at admission was 21.7% and that of chronic undernutrition was 10%. The prevalence of acute undernutrition at discharge rose to 34%. Weight loss during hospitalization was noted in 68.3% of cases. The prevalence of HUN was 55% considering a decrease in BMI or P/PAT z-score ≥ 25%. The risk factors for HUN were: age ≤ 24 months (P = 0.039; OR 95% CI = 2.67 [1.05–6.82]), the presence of undernutrition on admission (P = 0.002; OR 95% CI = 2.32 [0.93–6.51]) and average food consumption < 50% during hospitalization (P < 10^?3; OR 95% CI = 6.69 [2.57–17.40]).ConclusionScreening for undernutrition on admission to hospital as well as assessment of the nutritional risk in hospitalized children is essential so that preventive or curative nutritional care can be taken.     

Levels of physical activity and relationship with markers of diabetes and cardiovascular disease risk in 5474 white European and South Asian adults screened for type 2 diabetes

ObjectiveInvestigate levels of physical activity and their association with health in a white European (WE) and South Asian (SA) population.MethodsThis study reports data from a diabetes screening programme, 2004–2007, Leicester, UK. Physical activity was measured using the International Physical Activity Questionnaire; additional outcomes included fasting and 2-h post-challenge glucose, lipid profile, body mass index (BMI) and waist circumference.Results1164 SA (female = 48%) and 4310 WE (female = 53%) were included. SAs were more likely fall below the minimum physical activity recommendations for health compared to WEs (age-adjusted OR for SA men = 2.35; 95% CI = 1.89–2.93, age adjusted OR for SA women = 2.25; 95% CI = 1.81–2.80). There were significant associations between levels of physical activity and BMI (men and women), waist circumference (men and women), 2-h glucose (women), HDL-cholesterol (men) and triglycerides (men) in WEs and waist circumference (women) and HDL-cholesterol (men) in SAs. Significant interactions between ethnicity and physical activity existed in the relationship with BMI and waist circumference in men.ConclusionsSAs are substantially less physically active than WEs. There may also be differences between SAs and WEs in the health benefits associated with higher physical activity that warrant further investigation.     

Lack of association between Toll-like receptor 4 gene Asp299Gly and Thr399Ile polymorphisms and tuberculosis susceptibility: A meta-analysis

ObjectiveToll-like receptor 4 (TLR4) plays a vital role in immunity to tubercle bacillus and its gene polymorphisms are supposed to affect tuberculosis susceptibility in some rather than all studies. Then, we integrated published data and performed a comprehensive meta-analysis to get more reliable estimations for the strength of associations between TLR4 gene polymorphisms and the risk of tuberculosis.MethodsWe systematically searched the electronic PubMed database for research articles about TLR4 gene polymorphisms and tuberculosis up to February 2012. Revman 5.0 software was adopted to conduct the meta-analysis. Crude odds ratio (ORs) and 95% confidence intervals (95% CIs) were calculated by either fixed-effects model or random-effects model.ResultsFinally, six case-control studies were identified, involving 1587 controls and 2110 patients. Overall, no significant associations were found between TLR4 gene Asp299Gly polymorphism and tuberculosis in the codominant models (GG vs AA: OR = 1.56, 95% CI = 0.76–3.21, P = 0.23; GA vs AA: OR = 1.01, 95% CI = 0.84–1.23, P = 0.89), the dominant model (GG + GA vs AA: OR = 1.04, 95% CI = 0.80–1.35, P = 0.75), the recessive model (GG vs GA + AA: OR = 1.55, 95% CI = 0.75–3.19, P = 0.24) and the allele model (G vs A: OR = 1.06, 95% CI = 0.81–1.40, P = 0.66). Similarly, no significant associations between TLR4 gene Thr399Ile and tuberculosis were observed (all P > 0.05).ConclusionsThe present meta-analysis suggests that TLR4 gene Asp299Gly and Thr399Ile polymorphisms are not associated with the susceptibility of tuberculosis.     

Food environments in schools and in the immediate vicinity are associated with unhealthy food consumption among Brazilian adolescents

BackgroundEvidence of the influence of the school food environment on adolescent diet is still little explored in low- and middle-income countries. We aimed to evaluate the association between food environment in schools and the immediate vicinity and the regular consumption of unhealthy food among adolescents.MethodsWe used cross-sectional data collected by the Brazilian National Survey of School Health (PeNSE) from a representative sample of adolescents attending 9th grade public and private schools in Brazil, in 2012. We estimated students' regular consumption (> 5 days/week) of unhealthy food (soft drinks, bagged salty snacks, deep fried salty snacks and sweets) and school availability, in the cafeteria or an alternative outlet, of the same food plus some healthy options (fruit and natural fruit juice). We performed multilevel logistic regression models.ResultsHaving a cafeteria inside school selling soft drinks (private schools OR = 1.23; 95% CI = 1.14–1.33; public schools OR = 1.13; 95% CI = 1.06–1.20) and deep fried salty snacks (private schools OR = 1.41 95% CI = 1.26–1.57; public schools OR = 1.16 95% CI = 1.08–1.24) was associated with a higher consumption of these unhealthy foods of among students. In private schools, cafeteria selling fruit and natural fruit juice was associated with lower student consumption of bagged salty snacks (OR = 0.86; 95% CI 0.77–0.96) and soft drinks (OR = 0.85; 95% CI = 0.76–0.94). In addition, eating meals from the Brazilian School Food Program in public schools was associated with a lower consumption of unhealthy foods.ConclusionsFoods available in the school food environment are associated with the consumption of unhealthy food among adolescents in Brazil.     

Accelerometer determined sedentary behavior and dietary quality among US adults

ObjectiveScant evidence exists pertaining to objectively measured sedentary time and dietary quality among adults. Therefore, we examined the relationships between sedentary time, physical activity, and dietary quality.MethodsCross-sectional analyses of a 4,910 US adults from two cycles (2003–2006) of the National Health and Nutrition Examination Survey. The primary independent variables were sedentary time and physical activity (continuous and categorical), while the outcomes were overall dietary quality (Healthy Eating Index (HEI) 2010), fruit and vegetable scores, and empty caloric intake (kcal).ResultsMultivariable analyses revealed that a 1 min increase in daily sedentary behavior was associated with a 0.2 kcal decrease in empty calories (− 0.18, 95% CI = − 0.34, − 0.03); however, sedentary time was not significantly related to overall dietary quality (HEI) and fruit and vegetable intake. In comparison, a 1 min increase in daily moderate-to-vigorous intensity physical activity was related to a 0.1 higher HEI score (0.08, 95% CI = 0.04, 0.11), a 0.01 higher fruit score (0.01, 95% CI = 0.01, 0.02), and conversely a 1.3 kcal decrease in empty calories (− 1.35, 95% CI = − 2.01, − 0.69). In addition, meeting physical activity guidelines was associated with a 2.8 point higher HEI score (2.82, 95% CI = 1.40, 4.25), a 0.5 point higher fruit score (0.51, 95% CI = 0.31–0.71), and 37.4 fewer empty calories (− 37.43, 95% CI = − 64.86, − 9.10).ConclusionsPhysical activity is significantly related to better overall dietary quality, while sedentary behavior is not. Findings suggest the need to promote physical activity and encourage adherence to dietary guidelines jointly, whereas sedentary behavior and overall dietary quality might need to be targeted independently.     

Analysis of TLR4 (Asp299Gly and Thr399Ile) gene polymorphisms and mRNA level in patients with dengue infection: A case-control study

BackgroundDengue is a systemic viral infection that spreads to humans by the bite of infected Aedes mosquitoes. The secreted NS1 protein of dengue virus activates macrophages and human PBMCs via TLR4 and induce the release of pro-inflammatory cytokines which is responsible for the pathogenesis of disease. Mutations in TLR4 gene have been associated with the increased susceptibility to many viral, bacterial and parasitic diseases.ObjectiveTo study the impact of TLR4 Asp299Gly (rs4986790) and Thr399Ile (rs4986791) gene polymorphisms with susceptibility to dengue infection.MethodsA total of 120 dengue infected (57; DHF/DSS and 63; DF) and 200 healthy controls were included in the study. TLR4 Asp299Gly and Thr399Ile gene polymorphisms was studied by PCR-RFLP. Expression of TLR4 mRNA was evaluated by rRT-PCR.ResultsIndividuals with heterozygous genotype for TLR4 Asp299Gly and Thr399Ile polymorphisms had increased susceptibility to dengue infection (OR-1.70, 95% CI = 1.01–2.86 P = 0.042 and OR-2.17, 95% CI = 1.10–4.28, P = 0.024, respectively). The frequency of Gly and Ile alleles were higher in dengue patients as compared to controls (OR-1.67, 95% CI = 1.05–2.64, P = 0.029 and OR-2.20, 95% CI = 1.19–4.07, P = 0.011, respectively). IIe/Gly haplotype was associated with the risk of the disease when compared with controls (OR = 3.15, 95% CI = 1.09–9.09, P = 0.035). The mRNA expression was higher in DF when compared with DHF/DSS and controls (P = 0.040 and 0.009, respectively).ConclusionA higher expression of TLR4 mRNA was associated with DF. The TLR4 Asp299Gly and Thr399Ile gene polymorphisms were associated with the susceptibility of dengue infection probably by altering the immune response.     

Annual influenza vaccination reduces total hospitalization in patients with chronic hepatitis B virus infection: A population-based analysis

BackgroundThis study evaluated hospitalization and mortality in patients with chronic hepatitis B virus infection (HBV (+)) and matched comparison patients after stratifying the patients according to annual influenza vaccination (Vaccine (+)).MethodsData from Taiwan's National Health Insurance program from 2000 to 2009 were used to identify HBV(+)/vaccine(+) (n = 4434), HBV(+)/Vaccine(−) (n = 3646), HBV(−)/Vaccine(+) (n = 8868), and HBV(−)/Vaccine(−) (n = 8868) cohorts. The risk of pneumonia/influenza, respiratory failure, intensive care, hospitalization, and mortality in the four cohorts was evaluated.ResultsThe total hospitalization rate was significantly lower in patients with chronic HBV infection who received an annual influenza vaccination than in chronic HBV-infected patients who did not receive an influenza vaccination (16.29 vs. 24.02 per 100 person-years), contributing to an adjusted hazard ratio (HR) of 0.56 (95% confidence interval (CI) = 0.50–0.62). The HBV(+)/Vaccine(+) cohort also had lower risks than the HBV(+)/Vaccine(−) cohort for pneumonia and influenza (adjusted HR = 0.79, 95% CI = 0.67–0.92), intensive care unit admission (adjusted HR = 0.33, 95% CI = 0.25–0.43), and mortality (adjusted HR = 0.19, 95% CI = 0.15–0.24).ConclusionsOur results suggest that annual influenza vaccination can reduce the risk of hospitalization and mortality in patients with chronic HBV infection.     

Immigration Measures and Reproductive Health Among Hispanic Youth: Findings from the National Longitudinal Survey of Youth, 1997–2003

PurposeTo explore relationships between immigration measures and risk of reproductive and sexual events among U.S. Hispanic adolescents.MethodsWe examined generation status, language in the home and country of origin in relation to sexual activity, contraception, and childbearing among 1614 Hispanic adolescents, using nationally representative 1997–2003 longitudinal data. Multivariable analyses controlled for potentially confounding variables. Tests for effect modification by gender and Mexican origin were conducted.ResultsFewer first generation adolescents transitioned to sexual intercourse before age 18 (odds ratio [OR] = .80, 95% confidence interval [CI] = .66–.98) and fewer first and second generation sexually active teens used contraceptives consistently at age 17 (OR = .32, 95% CI = .17–.60 and OR = .50, 95% CI = .31–.80, respectively) than third-generation teens. Language was similarly associated with the transition to sexual intercourse and contraceptive practices. Versus teens of Mexican origin, teens of Puerto Rican origin and origins other than Cuba and Central/South America had greater odds of becoming sexually active; youth of all origins except Central/South America had fewer multiple live births (OR = .14–.31). Gender modified the effects of generation on consistent use of contraceptives and condoms at age 17. Gender also modified the effect of country of origin on transitioning to sexual intercourse before age 18 years.ConclusionsResults expand on previous observations that generation, language, and country of origin are predictors of reproductive and sexual risks for Hispanic adolescents. These immigration measures may therefore be useful in targeting community and clinical preventive services.     

School bullying and susceptibility to smoking among never-tried cigarette smoking students

IntroductionBullying involvement has been linked with substance use; however, less is known about its relationship with pre-initiation stages of adolescent cigarette smoking behavior. This study examined the association between bullying involvement and smoking susceptibility among never tried or experimented with cigarette smoking students. Susceptibility to cigarette smoking in adolescence is a strong predictor of subsequent smoking initiation.MethodsA cross-sectional data on Canadian adolescent and youth were drawn from the 2012/2013 Youth Smoking Survey (n = 28,843). Logistic regression analysis was used to examine the association between bullying and smoking susceptibility among never-smoking students.ResultsAbout 21% self-reported involvement in bullying (as a bully, victim or both). Middle school students (grades 6–8) reported more involvement in bullying (24%) than those in grades 9–12 (16%). The multivariable analyses showed that the association between bullying and smoking susceptibility was significantly different by grade level. Middle school students involved in bullying had higher odds of smoking susceptibility compared to uninvolved students (bully, adjusted odds ratio [AOR] = 2.54, 95% CI = 1.73–3.74; victim, AOR = 1.29, 95% CI = 1.11–1.48; bully–victim, AOR = 2.19, 95% CI = 1.75–2.74). There were no significant associations between all subgroups of bullying and smoking susceptibility for grades 9–12 students.ConclusionsStudents involved in bullying were more susceptible to smoking, although patterns of association varied by grade level. In particular, the findings highlight that non-smoking middle school students involved in bullying were susceptible to future smoking.     

Menopause and metabolic syndrome in obese individuals with binge eating disorder

Menopausal transition has been associated with the emergence of metabolic abnormalities, which may increase risk for chronic medical conditions in women. This study compared metabolic function between premenopausal women (n = 152), postmenopausal women (n = 88), and men (n = 98) recruited for treatment studies for obesity co-occurring with binge eating disorder (BED), a high-risk population for developing metabolic syndrome (MetS). Postmenopausal women were more likely than premenopausal women to show elevated total cholesterol (OR = 2.75; 95% CI = 1.56–4.80) and poor glycemic control (OR = 2.92; 95% CI = 1.32–6.33) but were more likely to have lower HDL levels (OR = 0.36; 95% CI = 0.19–0.68). These became non-significant after adjusting for age. Both pre- and postmenopausal women were less likely than age-matched men to show elevated levels of triglycerides (OR = 0.27; 95% CI = 0.13–0.53 [postmenopausal], OR = 0.29; 95% CI = 0.16–0.53 [premenopausal]), blood pressure (OR = 0.48; 95% CI = 0.25–0.91 [postmenopausal], OR = 0.40; 95% CI = 0.23–0.69 [premenopausal]), and less likely to have MetS (OR = 0.41; 95% CI = 0.21–0.78 [postmenopausal], OR = 0.46; 95% CI = 0.27–0.79 [premenopausal]). Premenopausal women were also less likely to have elevated fasting glucose level (OR = 0.50; 95% CI = 0.26–0.97) than age-matched men. Among obese women with BED, aging may have a more profound impact on metabolic abnormalities than menopause, suggesting the importance of early intervention of obesity and symptoms of BED. The active monitoring of metabolic function in obese men with BED may also be critical.     

Effets de la contamination chronique à l’uranium sur la mortalité : bilan d’une étude-pilote chez les travailleurs de l’industrie nucléaire en France

BackgroundThis article presents the mortality data compiled among a cohort of workers at risk of internal uranium exposure and discusses the extent to which this exposure might differentiate them from other nuclear workers.MethodsThe cohort consisted of 2897 Areva-NC-Pierrelatte plant workers, followed from 1st January 1968 through 31st December 2006 (79,892 person-years). Mortality was compared with that of the French population, by calculating Standardized Mortality Ratios (SMR) and 95 % confidence intervals (CI_95 %). External radiation exposure was reconstructed using external dosimetry archives. Internal uranium exposure was assessed using a plant-specific job-exposure-matrix, considering six types of uranium compounds according to their nature (natural and reprocessed uranium [RPU] and solubility [fast-F, moderate-M, and slow-S]). Exposure-effect analyses were performed for causes of death known to be related to external radiation exposure (all cancers and circulatory system diseases) and cancer of uranium target-organs (lung and hematopoietic and lymphatic tissues, HLT).ResultsA significant deficit of mortality from all causes (SMR = 0.58; CI_95 % [0.53–0.63]), all cancers (SMR = 0.72; CI_95 % [0.63–0.82]) and smoking related cancers was observed. Non-significant 30 %-higher increase of mortality was observed for cancer of pleura (SMR = 2.32; CI_95 % [0.75–5.41]), rectum and HLT, notably non-Hodgkin's lymphoma (SMR = 1.38; CI_95 % [0.63–2.61]) and chronic lymphoid leukemia (SMR = 2.36; CI_95 % [0.64–6.03]). No exposure-effect relationship was found with external radiation cumulative dose. A significant exposure-effect relationship was observed for slowly soluble uranium, particularly RPU, which was associated with an increase in mortality risk reaching 8 to 16 % per unit of cumulative exposure score and 10 to 15 % per year of exposure duration.ConclusionThe Areva-NC-Pierrelatte workers cohort presents a non-significant over-mortality from HLT cancers, notably of lymphoid origin, unrelated to external radiation exposure. The pilot study suggests an association between mortality from the HLT and lung cancers and exposure to slowly soluble RPU compounds. The results of this study should be investigated further in more powerful studies, with a dose-response analysis based on individual assessment of uranium absorbed dose to uranium-target organs.     

Eficacia de un programa de automedida domiciliaria de la presión arterial como estrategia para disminuir la inercia terapéutica

ObjectiveTo evaluate the efficacy of a program of home blood pressure monitoring (HBPM) on therapeutic Inertia (TI) in mild-to-moderate hypertension (AHT).DesignControlled, randomised clinical trial.SettingForty six clinics in 35 primary care centres. Spain.ParticipantsA total of 232 patients with uncontrolled hypertension were included.InterventionTwo groups with 116 patients were formed: 1) Control group (CG): standard health intervention; 2) Intervention group (IG): patients who were included in the HBPM program.Main measurementsTI was calculated by the ratio: Number of patients whose pharmacological treatment was not changed in each visit/Number of patients with an average BP 140mmHg and/or 90mmHg in the general population or 130 and/or 90 mmHg in diabetics. The mean BPs and the percentage of controlled patients were calculated. The mean number of people that required an intervention in order to avoid TI was calculated (NI).ResultsA total of 209 patients completed the study, with TI in 35.64% (95% CI = 29.85%-41.43%) of the sample, and in 71.63% (95% CI = 63.9-79.36%) of the uncontrolled hypertensive patients.The TI was 22.42% (95% CI = 24.2-37%) in the IG and 50% (95% CI = 37.75-62.25) in the CG (p < .05) in visit 2, and 25.23% (95% CI = 14.84-35.62) and 46.07% (95% CI = 33.85-58.29) in the final visit for IG and CG, respectively (P < .05). The NI was 4.3.ConclusionsTI was very significant among the uncontrolled hypertensive patients. The studied interventions are effective for improving TI.     

The 23-valent pneumococcal polysaccharide vaccine is effective in elderly adults over 75 years old—Taiwan's PPV vaccination program

BackgroundPneumococcal infection is a serious cause of mortality and morbidity in the elderly. A nationwide pneumococcal polysaccharide vaccine (PPV) program for elderly adults aged 75 years and older was conducted in Taiwan in 2008. The efficacy of the PPV in this very elderly population was evaluated.MethodsThe data were analyzed using the Taiwan National Health Insurance Research Database (NHIRD), the cause-of-death registration database and the invasive pneumococcal disease (IPD) notification database of Taiwan's Ministry of Health and Welfare. The efficacy of PPV administration in this very elderly population was evaluated using multivariate logistic regression after propensity score matching (PSM). The rates of IPD, death from IPD, pneumonia hospitalization, death from pneumonia, and all-cause mortality were compared for those who did and did not receive the PPV.ResultsAmong the 1078,955 eligible people, 318,257 (29.5%) received the PPV, and 760,698 (70.5%) were not vaccinated. Using PSM to adjust for confounding factors, including age, gender, influenza vaccination status, associated chronic diseases and health care utilization, those who received the PPV had significantly lower odds ratios (ORs) for IPD (OR = 0.24, 95% CI = 0.123–0.461, p < 0.001), death from IPD (OR = 0.09, 95% CI = 0.011–0.704, p < 0.022, p < 0.001), pneumonia hospitalization (OR = 0.40, 95% CI = 0.395–0.415, p < 0.001), death from pneumonia (OR = 0.07, 95% CI = 0.059–0.082, p < 0.001), and all-cause mortality (OR = 0.07, 95% CI = 0.069–0.072, p < 0.001) compared with those who were not vaccinated.ConclusionsPPV vaccination in the previous year was associated with a 60% reduction in pneumonia hospitalization, a 76% reduction in IPD, and a greater than 90% reduction in death from pneumonia, IPD and all causes among people over 75 years old in Taiwan. Data from subsequent years in Taiwan and similar populations elsewhere are needed to evaluate the contribution of underlying variations in the mortality rate and the confounding effects of prior disease severity to these findings.     

Psychological distress as a determinant of changes in body mass index over a period of 10 years

ObjectiveTo examine the longitudinal relationship between psychological distress and body mass index (BMI) changes over a period of five and ten years.MethodData were used from the Dutch, prospective, population based Doetinchem Cohort study over the period 1995/1999 until 2005/2009 (N = 5504). Psychological distress was assessed using the Mental Health Inventory (MHI-5). BMI (kg/m²) was calculated from measured body height and body weight. GEE analyses were used to examine the relationship between psychological distress at baseline and BMI change, and the development of overweight over five years. Linear and logistic regression analyses were used to examine these relations over ten years.ResultsPsychological distress predicted an extra overall increase in BMI of 0.14 kg/m² (95% CI 0.03–0.25) over five years and an increase of 0.18 kg/m² (95% CI 0.01–0.35) over ten years, when comparing psychologically distressed participants to psychologically healthy participants. This was especially the case among persons with normal weight (five years; B = 0.26 kg/m², 95% CI = 0.12–0.40/ten years; B = 0.32 kg/m² 95% CI = 0.11–0.53) and moderate overweight (five years: B = 0.18 kg/m², 95% CI = 0.02–0.35) at baseline. Psychological distress did not predict the development of overweight five and ten years later.ConclusionThe results in this study indicated that psychological distress predicted an increased risk in gaining weight, but did not result in an increased risk for developing overweight.
