Risk factors for new depressive episodes in primary health care: an international prospective 12-month follow-up study

Barkow, Katrin, Maier, Wolfgang, Üstün, T. Bedirhan, Gänsicke, Michael, Wittchen, Hans-Ulrich, Heun, Reinhard January 2002 (has links)
Background. Studies that examined community samples have reported several risk factors for the development of depressive episodes. The few studies that have been performed on primary care samples were mostly cross-sectional. Most samples had originated from highly developed industrial countries. This is the first study that prospectively investigates the risk factors of depressive episodes in an international primary care sample. Methods. A stratified primary care sample of initially non-depressed subjects (N = 2445) from 15 centres from all over the world was examined for the presence or absence of a depressive episode (ICD-10) at the 12 month follow-up assessment. The initial measures addressed sociodemographic variables, psychological/psychiatric problems and social disability. Logistic regression analysis was carried out to determine their relationship with the development of new depressive episodes. Results. At the 12-month follow-up, 4·4% of primary care patients met ICD-10 criteria for a depressive episode. Logistic regression analysis revealed that the recognition by the general practitioner as a psychiatric case, repeated suicidal thoughts, previous depressive episodes, the number of chronic organic diseases, poor general health, and a full or subthreshold ICD-10 disorder were related to the development of new depressive episodes. Conclusions. Psychological/psychiatric problems were found to play the most important role in the prediction of depressive episodes while sociodemographic variables were of lower importance. Differences compared with other studies might be due to our prospective design and possibly also to our culturally different sample. Applied stratification procedures, which resulted in a sample at high risk of developing depression, might be a limitation of our study.

Friedrich, Nele, Schneider, Harald Jörn, Dörr, Marcus, Nauck, Matthias, Völzke, Henry, Klotsche, Jens, Sievers, Caroline, Pittrow, David, Böhler, Steffen, Lehnert, Hendrik, Pieper, Lars, Wittchen, Hans-Ulrich, Wallaschofski, Henri, Stalla, Günter Karl January 2011 (has links)
Objective: Previous population-based studies provided conflicting results regarding the association of total serum insulin-like growth factor I (IGF-I) and mortality. The aim of the present study was to assess the relation of IGF-I levels with all-cause mortality in a prospective study. Design: DETECT (Diabetes Cardiovascular Risk-Evaluation: Targets and Essential Data for Commitment of Treatment) is a large, multistage, and nationally representative study of primary care patients in Germany. The study population included 2463 men and 3603 women. Death rates were recorded by the respective primary care physician. Serum total IGF-I levels were determined by chemiluminescence immunoassays and categorized into three groups (low, moderate, and high) according to the sex- and age-specific 10th and 90th percentiles. Results: Adjusted analyses revealed that men with low [hazard ratio (HR) 1.70 (95% confidence interval [CI] 1.05–2.73), p=0.03] and high [HR 1.76 (95% CI 1.09–2.85), p=0.02] IGF-I levels had higher risk of all-cause mortality compared to men with moderate IGF-I levels. The specificity of low IGF-I and high IGF-I levels increased with lower and higher cut-offs, respectively. No such association became apparent in women. Conclusions: The present study revealed a U-shaped relation between IGF-I and all-cause mortality in male primary care patients.

Deutsch, Tobias, Lippmann, Stefan, Heitzer, Maximilian, Frese, Thomas, Sandholzer, Hagen 29 June 2016 (has links) (PDF)
Background: To be able to counter the increasing shortage of general practitioners (GPs) in many countries, it is crucial to remain up‑to‑date with the decisive reasons why young physicians choose or reject a career in this field. Materials and Methods: Qualitative content analysis was performed using data from a cross‑sectional survey among German medical graduates (n = 659, response rate = 64.2%). Subsequently, descriptive statistics was calculated. Results: The most frequent motives to have opted for a GP career were (n = 74/81): Desire for variety and change (62.2%), interest in a long‑term bio‑psycho‑social treatment of patients (52.7%), desire for independence and self‑determination (44.6%), positively perceived work‑life balance (27.0%), interest in contents of the field (12.2%), and reluctance to work in a hospital (12.2%). The most frequent motives to have dismissed the seriously considered idea of becoming a GP were (n = 207/578): Reluctance to establish a practice or perceived associated risks and impairments (33.8%), stronger preference for another field (19.3%), perception of workload being too heavy or an unfavorable work‑life balance (15.0%), perception of too low or inadequate earning opportunities (14.0%), perception of the GP as a \"distributor station\" with limited diagnostic and therapeutic facilities (11.6%), perception of too limited specialization or limited options for further sub‑specialization (10.6%), rejection of (psycho‑) social aspects and demands in general practice (9.7%), and perceived monotony (9.7%). Conclusion: While some motives appear to be hard to influence, others reveal starting points to counter the GP shortage, in particular, with regard to working conditions, the further academic establishment, and the external presentation of the specialty.

International Day for the Evaluation of Abdominal obesity: rationale and design of a primary care study on the prevalence of abdominal obesity and associated factors in 63 countries

Wittchen, Hans-Ulrich, Balkau, Beverley, Massien, Christine, Richard, Alain, Haffner, Steven, Després, Jean-Pierre 27 February 2013 (has links) (PDF)
Sedentary lifestyles and energy-rich diets are driving an increasing prevalence of abdominal obesity, which is associated with cardiovascular risk. Reliable estimates of the worldwide prevalence of abdominal obesity are needed to quantify the associated health risk. The International Day for the Evaluation of Abdominal obesity (IDEA) study is a large, international epidemiological cross-sectional study designed to provide reliable data on the distribution of waist circumference according to region, gender, age, and socio-economic level in 177 345 primary care patients from 63 countries across five continents. Any non-pregnant patient aged 18–80 consulting one of the randomly selected primary care physicians on two pre-defined half days was eligible to participate in the study. The primary objective was to estimate the prevalence of abdominal obesity in primary care, in each participating country. Secondary objectives were to estimate the prevalence of hypertension, type 2 diabetes, dyslipidaemia, and smoking, and to evaluate their associations with abdominal obesity, according to age, gender, and socio-economic level and region. The IDEA study will provide the first global map of the prevalence of abdominal obesity and associated comorbidities in primary care practice.

Resting heart rate as a tool for risk stratification in primary care: does it provide incremental prognostic information?

Leistner, David M., Klotsche, Jens, Palm, Sylvia, Pieper, Lars, Stalla, Günter K., Lehnert, Hendrik, Silber, Sigmund, März, Winfried, Wittchen, Hans-Ulrich, Zeiher, Andreas M. 21 September 2013 (has links) (PDF)
Background: Several selected population-based studies have emphasized the significance of resting heart rate as an independent cardiovascular risk factor. However, there are no data available for using resting heart rate as a cardiovascular risk predictor in contemporary primary care. Thus, the aim of our analysis was to examine the clinical value of the measurement of resting heart rate in a large, unselected population-based cohort of primary care subjects under the conditions of contemporary primary prevention. Design: Prospective, population-based cohort study. Methods: We examined a subgroup of 5320 unselected primary care subjects free of coronary artery disease from the nationwide, longitudinal Diabetes Cardiovascular Risk Evaluation Targets and Essential Data for Commitment of Treatment (DETECT) cohort study, which was conducted from 2003 to 2008. Results: During the follow-up time of 5 years, 258 events were reported. Elevated resting heart rate was not associated with an increased risk for cardiovascular events (HR = 0.75, p = 0.394), cardiovascular mortality (HR = 0.71, p = 0.616) or major cardiovascular events (HR = 0.77, p = 0.376). By cross-sectional analysis, elevated heart rate clustered with markers of the metabolic syndrome, like increased blood pressure (systolic: OR = 5.54, p < 0.0001; diastolic: OR = 3.82, p < 0.0001), elevated fasting plasma glucose levels (OR = 8.84, p < 0.0001), hypertriglyceridaemia (OR = 22.16, p = 0.001), and obesity (body mass index OR = 0.89, p < 0.0001). Assessment of resting heart rate in clinical practice had minimal and non-significant additional prognostic value compared to established cardiovascular risk factors as judged by C statistics (C = 0.001, p = 0.979). Conclusion: The measurement of resting heart rate in the daily routine of primary care does not provide incremental prognostic information for cardiovascular risk stratification.

Peripheral Arterial Disease as an Independent Predictor for Excess Stroke Morbidity and Mortality in Primary-Care Patients: 5-Year Results of the getABI Study

Meves, Saskia H., Diehm, Curt, Berger, Klaus, Pittrow, David, Trampisch, Hans-Joachim, Burghaus, Ina, Tepohl, Gerhart, Allenberg, Jens-Rainer, Endres, Heinz G., Schwertfeger, Markus, Darius, Harald, Haberl, Roman L. 26 February 2014 (has links) (PDF)
Background:There is controversial evidence with regard to the significance of peripheral arterial disease (PAD) as an indicator for future stroke risk. We aimed to quantify the risk increase for mortality and morbidity associated with PAD. Methods:In an open, prospective, noninterventional cohort study in the primary care setting, a total of 6,880 unselected patients ≧65 years were categorized according to the presence or absence of PAD and followed up for vascular events or deaths over 5 years. PAD was defined as ankle-brachial index (ABI) <0.9 or history of previous peripheral revascularization and/or limb amputation and/or intermittent claudication. Associations between known cardiovascular risk factors including PAD and cerebrovascular mortality/events were analyzed in a multivariate Cox regression model. Results:During the 5-year follow-up [29,915 patient-years (PY)], 183 patients had a stroke (incidence per 1,000 PY: 6.1 cases). In patients with PAD (n = 1,429) compared to those without PAD (n = 5,392), the incidence of all stroke types standardized per 1,000 PY, with the exception of hemorrhagic stroke, was about doubled (for fatal stroke tripled). The corresponding adjusted hazard ratios were 1.6 (95% confidence interval, CI, 1.1–2.2) for total stroke, 1.7 (95% CI 1.2–2.5) for ischemic stroke, 0.7 (95% CI 0.2–2.2) for hemorrhagic stroke, 2.5 (95% CI 1.2–5.2) for fatal stroke and 1.4 (95% CI 0.9–2.1) for nonfatal stroke. Lower ABI categories were associated with higher stroke rates. Besides high age, previous stroke and diabetes mellitus, PAD was a significant independent predictor for ischemic stroke. Conclusions:The risk of stroke is substantially increased in PAD patients, and PAD is a strong independent predictor for stroke. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Who wants to become a general practitioner?

Deutsch, Tobias, Lippmann, Stefan, Frese, Thomas, Sandholzer, Hagen 12 March 2015 (has links) (PDF)
Objective: Because of the increasing shortage of general practitioners (GPs) in many countries, this study aimed to explore factors related to GP career choice in recent medical graduates. Particular focus was placed on the impact of specific practice-orientated GP courses at different stages of the medical undergraduate curriculum. Design: Observational study. Multivariable binary logistic regression was used to reveal independent associations with career choice. Setting: Leipzig Medical School, Germany. Subjects: 659 graduates (response rate = 64.2%). Main outcome measure: Choice of general practice as a career. Results: Six student-associated variables were found to be independently related to choice of general practice as a career: age, having family or friends in general practice, consideration of a GP career at matriculation, preference for subsequent work in a rural or small-town area, valuing the ability to see a broad spectrum of patients, and valuing long-term doctor – patient relationships. Regarding the curriculum, after adjustment independent associations were found with a specifi c pre-clinical GP elective (OR = 2.6, 95% CI 1.3 – 5.3), a four-week GP clerkship during the clinical study section (OR = 2.6, 95% CI 1.3 – 5.0), and a four-month GP clinical rotation during the final year (OR = 10.7, 95% CI 4.3 – 26.7). It was also found that the work-related values of the female participants were more compatible with those of physicians who opt for a GP career than was the case for their male colleagues. Conclusion: These results support the suggestion that a practice-orientated GP curriculum in both the earlier and later stages of undergraduate medical education raises medical schools’ output of future GPs. The findings are of interest for medical schools (curriculum design, admission criteria), policy-makers, and GPs involved in undergraduate medical education. More research is needed on the effectiveness of specific educational interventions in promoting interest in general practice as a career.
