Sexual and Reproductive Health Behaviors of Undocumented Migrants in Geneva: A Cross Sectional Study

Undocumented migrants face major barriers in accessing prevention and health care. Whereas the association between low socioeconomic status and poor health is well documented only few studies have addressed specific health issues in undocumented migrants. The aim of the present study is to describe sexual and reproductive health behaviors of undocumented migrants in Geneva. This descriptive cross sectional study included consecutive undocumented migrants presenting from November 2007 to February 2008 to a health facility offering free access to health care to this population. Following informed consent, they completed a self administered questionnaire about their socio-demographic profile and sexual and reproductive health behaviors. A total of 384 patients were eligible for the study. 313 (82%) agreed to participate of which 77% (241 patients) completed the survey. Participants were mainly young, Latino-American, single, well-educated and currently working women. They had multiple partners and reported frequently engaging in sexual intercourse. Use of contraceptive methods and strategies of prevention against sexually transmitted infections (STI) were rare. Nearly half of the women had had at least one induced abortion and 40% had had an unplanned pregnancy. One in four participants reported a current or past STI or other genital infection. The results of our study suggest that undocumented migrants engage in frequent and high risk sexual intercourse with insufficient use of contraceptive methods and suboptimal strategies of prevention against STI. Our study underlines the real need for specific sexual and reproductive educational programs targeting this hard to reach populatio

Consistency between cross-sectional and longitudinal SNP: blood lipid associations

Various studies have linked different genetic single nucleotide polymorphisms (SNPs) to different blood lipids (BL), but whether these "connections” were identified using cross-sectional or longitudinal (i.e., changes over time) designs has received little attention. Cross-sectional and longitudinal assessments of BL [total, high-, low-density lipoprotein cholesterol (TC, HDL, LDL), triglycerides (TG)] and non-genetic factors (body mass index, smoking, alcohol intake) were measured for 2,002 Geneva, Switzerland, adults during 1999-2008 (two measurements, median 6years apart), and 20 SNPs in 13 BL metabolism-related genes. Fixed and mixed effects repeated measures linear regression models, respectively, were employed to identify cross-sectional and longitudinal SNP:BL associations among the 1,516 (76%) study participants who reported not being treated for hypercholesterolemia at either measurement time. One-third more (12 vs. 9) longitudinal than cross-sectional associations were found [Bonferroni-adjusted two-tailed p<0.00125 (=0.05/2)/20) for each of the four ensembles of 20 SNP:individual BL associations tested under the two study designs]. There was moderate consistency between the cross-sectional and longitudinal findings, with eight SNP:BL associations consistently identified across both study designs: [APOE.2 and APOE.4 (rs7412 and rs429358)]:TC; HL/LIPC (rs2070895):HDL; [APOB (rs1367117), APOE.2 and APOE.4 (rs7412 and rs429358)]:LDL; [APOA5 (rs2072560) and APOC III (rs5128)]:TG. The results suggest that cross-sectional studies, which include most genome-wide association studies (GWAS), can assess the large majority of SNP:BL associations. In the present analysis, which was much less powered than a GWAS, the cross-sectional study was around 2/3 (67%) as efficient as the longitudinal stud

Age and quality of in-hospital care of patients with heart failure

Background: Elderly patients may be at risk of suboptimal care. Thus, the relationship between age and quality of care for patients hospitalized for heart failure was examined. Methods: A cross-sectional study based on retrospective chart review was performed among a random sample of patients hospitalized between 1996 and 1998 in the general internal medicine wards, with a principal diagnosis of congestive heart failure, and discharged alive. Explicit criteria of quality of care, grouped into three scores, were used: admission work-up (admission score); evaluation and treatment during the stay (evaluation and treatment score); and readiness for discharge (discharge score). The associations between age and quality of care scores were analysed using linear regression models. Results: Charts of 371 patients were reviewed. Mean age was 75.7 (±11.1) years and 52% were men. There was no relationship between age and admission or readiness for discharge scores. The evaluation and treatment score decreased with age: compared with patients less than 70 years old, the score was lower by −2.6% (95% CI: −7.1 to 1.9) for patients aged 70 to 79, by −8.7% (95% CI: −13.0 to −4.3) for patients aged 80 to 89, and by −19.0% (95% CI: −26.6 to −11.5) for patients aged 90 and over. After adjustment for possible confounders, this relationship was not significantly modified. Conclusions: In patients hospitalized for congestive heart failure, older age was not associated with lower quality of care scores except for evaluation and treatment. Whether this is detrimental to elderly patients remains to be evaluate

Spatial Dependence of Body Mass Index: Geneva, Switzerland

Urban health (UH) is an emerging field, which explores the effect of urban environment and urbanization on health. Evidence suggests that urban environment can either positively influence health behaviors or be a health stressor. One key approach in UH is the use of georeferenced data and geographic information system (GIS). Mapping disease prevalence and trends provide insight into disease mechanisms and etiologies. An important limitation of GIS is that data sets have likely been collected separately by different agencies, often over different time periods.The Canton of Geneva deviates from this limitation as it has been collecting geographic and health-related information continuously since 1998 through the Unit of Population Epidemiology (UEP) of the Geneva University Hospitals and its Bus Santé study. Combining health-related data from the Bus Santé study and GIS, using Local Indicators of Spatial Association (LISA), the investigators detected significant spatial dependance with respect to BMI. The results clearly indicate that BMI levels are not distributed at random in the Canton of Geneva. Moreover, performing preliminary exploratory analyses on blood pressure, investigators have identified cluster of individuals with higher blood pressure than the average, lifting up possible influences of environmental/urban factors (e.g., sidewalks, traffic, socioeconomic status)

Trends in dietary intake in Switzerland, 1999 to 2009

Abstract Objective To assess nutrition trends of the Geneva population for the period 1999-2009. Design Bus Santé Geneva study, which conducts annual health surveys in random samples of the Geneva population. Dietary intake was assessed using a validated FFQ and trends were assessed by linear regression. Setting Population-based survey. Subjects Data from 9283 participants (50 % women, mean age 51·5 (sd 10·8) years) were analysed. Results In both genders total energy intake decreased from 1999 to 2009, by 2·9 % in men and by 6·3 % in women (both trends P < 0·005). Vegetable protein and total carbohydrate intakes, expressed as a percentage of total energy intake, increased in women. MUFA intake increased while SFA, PUFA and alcohol intakes decreased in both genders. Intakes of Ca, Fe and carotene decreased in both genders. No changes in fibre, vitamin D and vitamin A intakes were found. Similar findings were obtained after excluding participants with extreme dietary intakes, except that the decreases in SFA, vegetable protein and carbohydrate were no longer significant in women. Conclusions Between 1999 and 2009, a small decrease in total energy intake was noted in the Geneva population. Although the decrease in alcohol and SFA intakes is of interest, the decrease in Ca and Fe intakes may have adverse health effects in the futur

The Quality of Primary Care in a Country with Universal Health Care Coverage

BACKGROUND: Standard indicators of quality of care have been developed in the United States. Limited information exists about quality of care in countries with universal health care coverage. OBJECTIVE: To assess the quality of preventive care and care for cardiovascular risk factors in a country with universal health care coverage. DESIGN AND PARTICIPANTS: Retrospective cohort of a random sample of 1,002 patients aged 50-80years followed for 2years from all Swiss university primary care settings. MAIN MEASURES: We used indicators derived from RAND's Quality Assessment Tools. Each indicator was scored by dividing the number of episodes when recommended care was delivered by the number of times patients were eligible for indicators. Aggregate scores were calculated by taking into account the number of eligible patients for each indicator. KEY RESULTS: Overall, patients (44% women) received 69% of recommended preventive care, but rates differed by indicators. Indicators assessing annual blood pressure and weight measurements (both 95%) were more likely to be met than indicators assessing smoking cessation counseling (72%), breast (40%) and colon cancer screening (35%; all p 75% for hypertension, dyslipidemia and diabetes. However, foot examination was performed only in 50% of patients with diabetes. Prevention indicators were more likely to be met in men (72.2% vs 65.3% in women, p < 0.001) and patients <65years (70.1% vs 68.0% in those ≥65years, p = 0.047). CONCLUSIONS: Using standardized tools, these adults received 69% of recommended preventive care and 83% of care for cardiovascular risk factors in Switzerland, a country with universal coverage. Prevention indicator rates were lower for women and the elderly, and for cancer screening. Our study helps pave the way for targeted quality improvement initiatives and broader assessment of health care in Continental Europ

Prevalence and Associated Factors for Chlamydia trachomatis Infection Among Undocumented Immigrants in a Primary Care Facility in Geneva, Switzerland: A Cross-Sectional Study

Chlamydia trachomatis infection (CTI) is the most frequent sexually transmitted infection in western countries. Its prevalence in undocumented immigrants, a rapidly growing vulnerable population, remains unknown. We aimed to document the prevalence of CTI and associated factors at the primary health care level. This cross-sectional study included all undocumented immigrants attending a health care facility in Geneva, Switzerland. Participants completed a questionnaire and were tested for CTI by PCR assay. Three-hundred thirteen undocumented immigrants (68.4% female, mean age 32.4 (SD 8) years) agreed to participate. CTI prevalence was 5.8% (95% CI 3.3-8.4). Factors associated with higher prevalence were age ≤25 (OR 3.9, 95% CI 1.3-12.2) and having had two or more sexual partners during the precedent year (OR 4.5, 95% CI 1.5-13.7). Prevalence and associated factors for infection in this vulnerable population were comparable with other populations in Western countries. Our findings support the importance of facilitating access to existing screening opportunities in particular to individuals at higher ris

Effects of passive smoking on heart rate variability, heart rate and blood pressure: an observational study

Background Exposure to environmental tobacco smoke (ETS) has been shown to increase the risk for cardiovascular diseases and death, and autonomic dysfunction (specifically, reduced heart rate variability (HRV)) is a predictor of increased cardiac risk. This study tests the hypothesis that ETS exposure reduces HRV in the general population and discusses possible pathways. Methods This cross-sectional study was conducted between 2001 and 2003 and is part of the SAPALDIA (Swiss Cohort Study on Air Pollution and Lung Diseases in Adults) study. The analysis included 1218 randomly selected non-smokers aged 50 and above who participated in 24-h electrocardiogram recordings. Other examinations included an interview, investigating health status (especially respiratory and cardiovascular health and health relevant behaviours and exposure to ETS) and measurements of blood pressure, body height and weight. Results Subjects exposed to ETS at home or at work for more than 2 h/day had a difference of −15% in total power (95%CI: −26 to −3%), low frequency power (−28 to −1%), low/high frequency ratio (−26 to −3%) and −18% (−29 to −4%) in ultralow frequency power of HRV compared with subjects not exposed to ETS at home or work. We also found a 2.7% (−0.01 to 5.34%) higher heart rate during the recording in exposed subjects. Conclusions Exposure to ETS at home and work is associated with lower HRV and with higher heart rate in an ageing population. Our findings suggest that exposure to ETS increases cardiac risk through disturbances in the autonomic nervous syste

Effect of physical activity on heart rate variability in normal weight, overweight and obese subjects: results from the SAPALDIA study

Many studies have demonstrated an association of both a sedentary lifestyle and a high body mass index (BMI) with greater risk for cardiovascular disease. Within the prospective SAPALDIA cohort (Swiss cohort Study on Air Pollution and Lung Diseases in Adults), we investigated whether regular exercise was protective against reduced heart rate variability (HRV), a clinically relevant predictor of cardiovascular morbidity and mortality, and whether adverse effects of obesity and weight gain on HRV were modified by regular exercise. Twenty-four-hour electrocardiograms were recorded in 1,712 randomly selected SAPALDIA participants aged ≥50, for whom BMI was assessed in the years 1991 and 2001-2003. Other examinations included an interview investigating health status (especially respiratory and cardiovascular health and health relevant behaviours including physical activity) and measurements of blood pressure, body height and weight. The association between regular physical activity and HRV and interactions with BMI and BMI change was assessed in multivariable linear regression analyses. Compared to sedentary obese subjects, SDNN (standard deviation of all RR intervals) was 14% (95% CI: 8-20%) higher in sedentary normal weight subjects; 19% (CI: 12-27%) higher in normal weight subjects exercising regularly ≥2h/week; and 19% (CI: 11-28%) higher in obese subjects exercising regularly ≥2h/week. Compared with sedentary subjects who gained weight, those who gained weight but did exercise regularly had a 13% higher SDNN (CI: 7-20%). Regular physical exercise has strong beneficial effects on cardiac autonomic nervous function and thus appears to offset the negative effect of obesity on HR
