Global patterns of mortality in young people: a systematic analysis of population health data

BACKGROUND Pronounced changes in patterns of health take place in adolescence and young adulthood, but the effects on mortality patterns worldwide have not been reported. We analysed worldwide rates and patterns of mortality between early adolescence and young adulthood. METHODS We obtained data from the 2004 Global Burden of Disease Study, and used all-cause mortality estimates developed for the 2006 World Health Report, with adjustments for revisions in death from HIV/AIDS and from war and natural disasters. Data for cause of death were derived from national vital registration when available; for other countries we used sample registration data, verbal autopsy, and disease surveillance data to model causes of death. Worldwide rates and patterns of mortality were investigated by WHO region, income status, and cause in age-groups of 10-14 years, 15-19 years, and 20-24 years. FINDINGS 2.6 million deaths occurred in people aged 10-24 years in 2004. 2.56 million (97%) of these deaths were in low-income and middle-income countries, and almost two thirds (1.67 million) were in sub-Saharan Africa and southeast Asia. Pronounced rises in mortality rates were recorded from early adolescence (10-14 years) to young adulthood (20-24 years), but reasons varied by region and sex. Maternal conditions were a leading cause of female deaths at 15%. HIV/AIDS and tuberculosis contributed to 11% of deaths. Traffic accidents were the largest cause and accounted for 14% of male and 5% of female deaths. Other prominent causes included violence (12% of male deaths) and suicide (6% of all deaths). INTERPRETATION Present global priorities for adolescent health policy, which focus on HIV/AIDS and maternal mortality, are an important but insufficient response to prevent mortality in an age-group in which more than two in five deaths are due to intentional and unintentional injuries.

Youth-friendly primary-care services: how are we doing and what more needs to be done?

For developmental as well as epidemiological reasons, young people need youth-friendly models of primary care. Over the past two decades, much has been written about barriers faced by young people in accessing health care. Worldwide, initiatives are emerging that attempt to remove these barriers and help reach young people with the health services they need. In this paper, we present key models of youth-friendly health provision and review the evidence for the effect of such models on young peoples health. Unfortunately, little evidence is available, since many of these initiatives have not been appropriately assessed. Appropriate controlled assessments of the effect of youth-friendly health-service models on young peoples health outcomes should be the focus of future research agendas. Enough is known to recommend that a priority for the future is to ensure that each country, state, and locality has a policy and support to encourage provision of innovative and well assessed youth-friendly services.

Reliability of doctors' anthropometric measurements to detect obesity

OBJECTIVE To evaluate the reliability of anthropometric measurements (weight, height, Body Mass Index (BMI), waist and hip circumferences (WC; HC) and waist-to-hip ratio (WHR)) performed by doctors to assess obesity. METHOD Repeated anthropometric measurements were performed by 12 primary care physicians on 24 adult volunteers in Geneva, Switzerland, 2006. Volunteers (54% women, mean age 41) had a mean BMI of 28.1 (respective mean values for WC, HC and WHR: 91.4, 108.3, 0.84). Inter-observer reliability coefficient (R) and percent disagreement in categorisation of volunteers (normal weight, overweight, obesity, abdominal obesity) were computed according to these measurements. RESULTS The inter-observer reliability for weight, height, and derived BMI were excellent (R>0.99), but unsatisfactory for WC (R=0.92), HC (R=0.76) and WHR (R=0.51). Based on the BMI, only 1% of the volunteers were misclassified as overweight or obese, whereas the use of WC and WHR lead to misclassification in 6% and 23% respectively. Reliability for the measurements improved after a one-hour training in anthropometric measurements (R=0.97 for WC, 0.92 for HC and 0.89 for WHR), but the proportion who were misclassified remained high despite the training session for WC (5%) and WHR (9%). CONCLUSIONS BMI remains the most reliable measure to detect obesity in medical practice, whereas WC, HC and WHR are less reliable. These results challenge current recommendations on obesity-related cardio-vascular risk management based on WC and WHR and underline the need for further research to improve the reliability of anthropometric measurements by doctors.

Toward Youth Friendly Services: A Survey of Young People in Primary Care

The World Health Organization encourages the development of youth friendly services, yet little is known on how youth currently present in general practice. To describe the perspectives, expectations, and service receipt of young people presenting to family doctors to inform the development of youth friendly services. Cross-sectional survey. Consecutive young people attending 26 randomly selected practices were recruited in the waiting rooms. Standardized instruments were used to interview them before their consultation. Of 501 young people who were approached, 450 participated (91% participation rate). Most had respiratory (26%) or dermatological complaints (18%). When asked to assess their health status, 59% perceived they had neither a physical nor a mental illness. However, 43% stated they had fears about their health problem and 1 in 5 feared it could be life-threatening. Although only 10% presented with psychological complaints, 24% perceived they currently had a mental illness. The most common expectations were treatment (50%) and good communication (42%). Most youth were prescribed medication (60%), but 40% of those who received a prescription had not expected to receive a treatment. A follow-up appointment was offered to 57% of participants. This study identifies a gap between young people’s perception of illness and their presentations to family doctors. It also highlights unexpected fears, and a mismatch between expectations and service receipt. These findings have implications for family medicine training and for clinical practice. They should inform the development of youth friendly services.

Blood pressure measurements are unreliable to diagnose hypertension in primary care

Objectives: To evaluate the accuracy of blood pressure (BP) measurements performed by primary care physicians (PCPs), and to assess whether it improves following a short theoretical training. Methods: Observational study in 26 primary care practices in Geneva, Switzerland. The PCPs were asked to measure BP on 10 volunteers, within the usual context of their practice. Two trained research assistants repeated the measures immediately after the PCPs. The PCPs were then randomized to receive detailed training documentation on standardized BP measurement (group I: 14 doctors) or information about high BP (group II: 12 doctors). Measures were repeated a few weeks later. We computed accuracy and diagnostic categorization of high BP comparing the PCPs’ measurements to the average value of four measurements by the research assistants (gold standard). T-tests were used to compare measurements between the two educational groups, both at baseline and following exposure to the educational material. Results: BP measurements were performed on 257 volunteers at baseline and 251 after training. At baseline, the mean BP difference between PCPs and the gold standard were 23.0 mmHg (21.3–24.6) for systolic and 15.3 mmHg (14.3–16.3) for DBP. Following training, the mean difference remained high [group I: 22.3 mmHg (20.4–24.2) and 14.4 mmHg (12.6–16.2); group II: 25.3 mmHg (22.7–27.9) and 17.0 mmHg (15.3–18.7)]. As a result, 24–32% volunteers were misdiagnosed as having systolic hypertension and 15–21% as having diastolic hypertension. Conclusion: Though widely used in the assessment of hypertension in ambulatory settings, in-office BP measurements are highly inaccurate, even following training.

Impact of Interventions to Increase the Proportion of Medical Students Choosing a Primary Care Career: A Systematic Review

ABSTRACTBACKGROUNDIncreasing the attractiveness of primary care careers is a key step in addressing the growing shortage of primary care physicians. The purpose of this review was to (1) identify interventions aimed at increasing the proportion of undergraduate medical students choosing a primary care specialty, (2) describe the characteristics of these interventions, (3) assess the quality of the studies, and (4) compare the findings to those of a previous literature review within a global context.METHODSWe searched MEDLINE, EMBASE, ERIC, CINAHL, PsycINFO, The Cochrane Library, and Dissertations & Theses A&I for articles published between 1993 and February 20, 2015. We included quantitative and qualitative studies reporting on primary care specialty choice outcomes of interventions in the undergraduate medical curriculum, without geographic restrictions. Data extracted included study characteristics, intervention details, and relevant outcomes. Studies were assessed for quality and strength of findings using a five-point scale.RESULTSThe review included 72 articles reporting on 66 different interventions. Longitudinal programs were the only intervention consistently associated with an increased proportion of students choosing primary care. Successful interventions were characterized by diverse teaching formats, student selection, and good-quality teaching. Study quality had not improved since recommendations were published in 1995. Many studies used cross-sectional designs and non-validated surveys, did not include control groups, and were not based on a theory or conceptual framework.DISCUSSIONOur review supports the value of longitudinal, multifaceted, primary care programs to increase the proportion of students choosing primary care specialties. Isolated modules or clerkships did not appear to be effective. Our results are in line with the conclusions from previous reviews and add an international perspective, but the evidence is limited by the overall low methodological quality of the included studies. Future research should use more rigorous evaluation methods and include long-term outcomes.

Brief intervention addressing excessive cannabis use in young people consulting their GP: a pilot study

BACKGROUND When excessive cannabis consumption occurs in adolescence, the adverse consequences extend into adulthood. Interventions by GPs are effective in preventing harm associated with alcohol use. Similar interventions have potential in addressing cannabis use. AIM To develop and pilot test a brief intervention targeting excessive cannabis use (defined as > or = 1x/week) in young people in primary care. DESIGN OF THE STUDY Pilot intervention trial. SETTING Seven family practices in Switzerland. METHOD The team collaborated with GPs and young people to develop the intervention. Seven GPs piloted its use in their consultations. Patients aged 15 to 24 years consulting for any health problem were recruited before the consultation. Cannabis use, other substance use, and their psychosocial correlates were assessed with a short confidential questionnaire administered before the consultation and 1 month later. GPs, staff, and patients were asked to comment on the study and its feasibility. RESULTS Of 81 young people invited to participate, 78 (70% female) agreed (participation rate: 96%). One in seven (13.2%, 95% confidence interval = 7.5% to 18.9%) used cannabis at least once a week. Data at 1 month were available for 42% who had provided email contact details and 91% of those who had provided their mobile phone number (63% overall). In most cases, the intervention lasted no more than 5 minutes. Comments from participants added favourable data towards the feasibility of the study. CONCLUSION This pilot study provides a solid base on which to build a randomised trial of a brief intervention addressing cannabis use in young people consulting in family practice.

Psychiatric symptoms, psychological distress and somatic comorbidity among remand prisoners in Switzerland

OBJECTIVE The aims of this study were to determine the prevalence of psychiatric symptoms and complaints among remand prisoners in Switzerland and to analyze the relationships between psychiatric symptoms, physical health and substance abuse problems in this population. METHOD The medical files of all detainees attending the prison health service in 2007 were reviewed. Identified health problems were coded using the International Classification of Primary Care (ICPC-2). Descriptive statistics and measures of association were computed. RESULTS A total of 1510 files were analyzed. Several associations between psychological symptoms (anxiety and insomnia) and physical health problems (skin, respiratory and circulatory) were observed. Substance abuse was also frequently associated with somatic health problems. CONCLUSIONS These data provide the first comprehensive description of the mental health of detainees in Switzerlands largest remand prison. Our findings emphasize the need for coordinated health care services in detention settings.

Health problems among detainees in Switzerland: a study using the ICPC-2 classification

BackgroundLittle is known about the health status of prisoners in Switzerland. The aim of this study was to provide a detailed description of the health problems presented by detainees in Switzerlands largest remand prison.MethodsIn this retrospective cross-sectional study we reviewed the health records of all detainees leaving Switzerlands largest remand prison in 2007. The health problems were coded using the International Classification for Primary Care (ICPC-2). Analyses were descriptive, stratified by gender.ResultsA total of 2195 health records were reviewed. Mean age was 29.5 years (SD 9.5); 95% were male; 87.8% were migrants. Mean length of stay was 80 days (SD 160). Illicit drug use (40.2%) and mental health problems (32.6%) were frequent, but most of these detainees (57.6%) had more generic primary care problems, such as skin (27.0%), infectious diseases (23.5%), musculoskeletal (19.2%), injury related (18.3%), digestive (15.0%) or respiratory problems (14.0%). Furthermore, 7.9% reported exposure to violence during arrest by the police.ConclusionMorbidity is high in this young, predominantly male population of detainees, in particular in relation to substance abuse. Other health problems more commonly seen in general practice are also frequent. These findings support the further development of coordinated primary care and mental health services within detention centers.

YFHS-WHO+ Questionnaire: validation of a measure of youth-friendly primary care services.

PURPOSE To develop and validate a research tool to measure the youth friendliness of primary care services from a clients perspective. METHODS The questionnaire was initially developed in English, but as it was to be used in Bosnia and Herzegovina (BiH), it was validated in the language of this country. Items were adapted from two sources: a reproductive health services quality improvement questionnaire from the World Health Organization, and an Australian survey used to assess youth-friendly primary care services. An English-speaking international panel reviewed the list of items for face validity. After translation-back translation, the questionnaire was pretested with adolescent patients from a family practice in BiH. The stability and construct validation were then conducted with 60 young people from six different health services in BiH. Items for the final questionnaire were selected using item response theory. RESULTS The validation and item response analysis led to a 49-item tool. Test-retest stability at 1 week was excellent (mean κ: .93). Construct validation was supported by the fact that services with the highest and the lowest scores on the questionnaire were also those that had many and few, respectively, youth-friendly characteristics, as assessed by experts, on a predefined evaluation grid. Services seeing a higher proportion of adolescents also had higher scores on the questionnaire. CONCLUSIONS This study supports the validity of the YFHS-WHO+ questionnaire for assessing the level of youth friendliness of family medicine services for research purposes. Further validations in English and French will allow wider use of this tool in the future.
