A salutogenic approach to prevention of metabolic syndrome : a mixed methods population study

Objective. To find a salutogenic approach for prevention of metabolic syndrome in primary care practice. Design. An explanatory sequential mixed-methods procedure was used to fi nd salutogenic approaches for lifestyle change by assessing individual need, potential, and personal motivation. Data from a population health survey and interviews that focused on a sense of coherence were analysed. Subjects. Altogether 480 Finnish subjects participated in a population health survey, and 43 of them were interviewed. The 43 interviewees' data were included in the fi nal analysis. Main outcome measures. With the health survey participants' liability for MetS was assessed, and the objective need for lifestyle intervention was determined. Through the focused interviews potential and personal motivation for lifestyle modifi cation were explored. Finally the data of the 43 interviewed subjects were merged. Results. Four possible lifestyle intervention approaches were identifi ed for specifi c intervention. First, subjects with a strong sense of coherence only need encouragement to maintain a healthy lifestyle; second, professional support was found important for subjects with gaps in health awareness to improve health understanding; third, strengthening of social support for lifestyle change is necessary for subjects with various practical constraints in their everyday life; and fourth, strengthening of stress adaptation is important for subjects with redundant concerns about their health. Conclusions. Salutogenic client-centred lifestyle modifi cation approaches should be part of primary care practice. Further, a cross-disciplinary approach is needed in primary care research and practice to combat the exploding lifestyle illnesses.Peer reviewe

Doctor-patient interaction in Finnish primary health care as perceived by first year medical students

BACKGROUND: In Finland, public health care is the responsibility of primary health care centres, which render a wide range of community level preventive, curative and rehabilitative medical care. Since 1990's, medical studies have involved early familiarization of medical students with general practice from the beginning of the studies, as this pre-clinical familiarisation helps medical students understand patients as human beings, recognise the importance of the doctor-patient relationship and identify practicing general practitioners (GPs) as role models for their professional development. Focused on doctor-patient relationship, we analysed the reports of 2002 first year medical students in the University of Kuopio. The students observed GPs' work during their 2-day visit to primary health care centres. METHODS: We analysed systematically the texts of 127 written reports of 2002, which represents 95.5% of the 133 first year pre-clinical medical students reports. The reports of 2003 (N = 118) and 2004 (N = 130) were used as reference material. RESULTS: Majority of the students reported GPs as positive role models. Some students reported GPs' poor attitudes, which they, however, regarded as a learning opportunity. Students generally observed a great variety of responsibilities in general practice, and expressed admiration for the skills and abilities required. They appreciated the GPs' interest in patients concerns. GPs' communication styles were found to vary considerably. Students reported some factors disturbing the consultation session, such as the GP staring at the computer screen and other team members entering the room. Working with marginalized groups, the chronically and terminally ill, and dying patients was seen as an area for development in the busy Finnish primary health care centres. CONCLUSION: During the analysis, we discovered that medical students' perceptions in this study are in line with the previous findings about the importance of role model (good or bad) in making good doctors. Therefore, medical students' pre-clinical primary health care centre visits may influence their attitudes towards primary health care work and the doctor-patient relationship. We welcome more European studies on the role of early pre-clinical general practice exposure on medical students' primary care specialty choice

Cardiovascular disease, chronic kidney disease, and diabetes mortality burden of cardiometabolic risk factors from 1980 to 2010: A comparative risk assessment

Background: High blood pressure, blood glucose, serum cholesterol, and BMI are risk factors for cardiovascular diseases and some of these factors also increase the risk of chronic kidney disease and diabetes. We estimated mortality from cardiovascular diseases, chronic kidney disease, and diabetes that was attributable to these four cardiometabolic risk factors for all countries and regions from 1980 to 2010. Methods: We used data for exposure to risk factors by country, age group, and sex from pooled analyses of population-based health surveys. We obtained relative risks for the effects of risk factors on cause-specific mortality from meta-analyses of large prospective studies. We calculated the population attributable fractions for each risk factor alone, and for the combination of all risk factors, accounting for multicausality and for mediation of the effects of BMI by the other three risks. We calculated attributable deaths by multiplying the cause-specific population attributable fractions by the number of disease-specific deaths. We obtained cause-specific mortality from the Global Burden of Diseases, Injuries, and Risk Factors 2010 Study. We propagated the uncertainties of all the inputs to the final estimates. Findings: In 2010, high blood pressure was the leading risk factor for deaths due to cardiovascular diseases, chronic kidney disease, and diabetes in every region, causing more than 40% of worldwide deaths from these diseases; high BMI and glucose were each responsible for about 15% of deaths, and high cholesterol for more than 10%. After accounting for multicausality, 63% (10·8 million deaths, 95% CI 10·1-11·5) of deaths from these diseases in 2010 were attributable to the combined effect of these four metabolic risk factors, compared with 67% (7·1 million deaths, 6·6-7·6) in 1980. The mortality burden of high BMI and glucose nearly doubled from 1980 to 2010. At the country level, age-standardised death rates from these diseases attributable to the combined effects of these four risk factors surpassed 925 deaths per 100 000 for men in Belarus, Kazakhstan, and Mongolia, but were less than 130 deaths per 100 000 for women and less than 200 for men in some high-income countries including Australia, Canada, France, Japan, the Netherlands, Singapore, South Korea, and Spain. Interpretation: The salient features of the cardiometabolic disease and risk factor epidemic at the beginning of the 21st century are high blood pressure and an increasing effect of obesity and diabetes. The mortality burden of cardiometabolic risk factors has shifted from high-income to low-income and middle-income countries. Lowering cardiometabolic risks through dietary, behavioural, and pharmacological interventions should be a part of the global response to non-communicable diseases.

Unintended pregnancy and termination of studies among students in Anambra state, Nigeria: Are secondary schools playing their part?

This study evaluated efforts of secondary schools to prevent unintended pregnancy among students and their reactions to pregnant students before and after delivery. A cross-sectional survey of 46 teachers in three public and two private schools in Anambra state, Nigeria was carried out. Information was collected using self-administered questionnaire. Of all the teachers in the study, 87% reported unintended pregnancies among students in the previous 3 years. Expulsion (43%) and suspension (28%) were the most common reactions. Private schools were more likely to expel pregnant students than public schools. Following the delivery of their babies, 43% discontinued their education in the same school, whereas 37% continued their education in a different school. Counselling was given before suspension or expulsion in 4% of public schools and 15% of private schools. Majority of the schools (61%) did not have sex education as part of their schools' curriculum. Students should be re-admitted in order to ensure continuity of their academic development, prevent unemployment and mitigate poverty-induced repeat pregnancy.Cette étude a évalué les efforts des écoles secondaires pour prévenir les grossesses non voulues chez les étudiantes et leurs réactions envers les étudiantes enceintes avant et après l'accouchement. Nous avons mené une enquête transversale auprès de 46 enseignants dans trois écoles publiques et deux écoles privées dans l'état d'Anambra au Nigéria. Les données ont été collectées à travers un questionnaire auto-administré. De tous les enseignants concernés dans l'étude, 87% ont signalé les grossesses non voulues chez les étudiants au cour de trois ans précédents. Les réactions les plus communes ont été l'expulsion (43%) et le renvoi (28%). Les écoles privées avaient plus la possibilité d'expulser les étudiantes enceintes que les écoles publiques. Suite à l'accouchement de leurs bébés, 43% ont cessé de fréquenter la même école alors que 37% ont continué leurs études dans une autre école. Avant la suspension ou le renvoi, 4% des étudiantes enceintes dans les écoles publique ont reçu des conseils d'orientation et 15% dans les écoles privées. Dans la majorité des écoles (61%), l'éducation sexuelle ne figure sur programmes d'études. Il faut réadmettre les étudiantes pour assurer la continuité de leur progrès académique, prévenir le chômage et réduire la grossesse répétée causée par la pauvreté

National, regional, and global trends in systolic blood pressure since 1980: systematic analysis of health examination surveys and epidemiological studies with 786 country-years and 5.4 million participants

Background Data for trends in blood pressure are needed to understand the effects of its dietary, lifestyle, and pharmacological determinants; set intervention priorities; and evaluate national programmes. However, few worldwide analyses of trends in blood pressure have been done. We estimated worldwide trends in population mean systolic blood pressure (SBP)

National, regional, and global trends in adult overweight and obesity prevalences

Background: Overweight and obesity prevalence are commonly used for public and policy communication of the extent of the obesity epidemic, yet comparable estimates of trends in overweight and obesity prevalence by country are not available.Methods: We estimated trends between 1980 and 2008 in overweight and obesity prevalence and their uncertainty for adults 20 years of age and older in 199 countries and territories. Data were from a previous study, which used a Bayesian hierarchical model to estimate mean body mass index (BMI) based on published and unpublished health examination surveys and epidemiologic studies. Here, we used the estimated mean BMIs in a regression model to predict overweight and obesity prevalence by age, country, year, and sex. The uncertainty of the estimates included both those of the Bayesian hierarchical model and the uncertainty due to cross-walking from mean BMI to overweight and obesity prevalence.Results: The global age-standardized prevalence of obesity nearly doubled from 6.4% (95% uncertainty interval 5.7-7.2%) in 1980 to 12.0% (11.5-12.5%) in 2008. Half of this rise occurred in the 20 years between 1980 and 2000, and half occurred in the 8 years between 2000 and 2008. The age-standardized prevalence of overweight increased from 24.6% (22.7-26.7%) to 34.4% (33.2-35.5%) during the same 28-year period. In 2008, female obesity prevalence ranged from 1.4% (0.7-2.2%) in Bangladesh and 1.5% (0.9-2.4%) in Madagascar to 70.4% (61.9-78.9%) in Tonga and 74.8% (66.7-82.1%) in Nauru. Male obesity was below 1% in Bangladesh, Democratic Republic of the Congo, and Ethiopia, and was highest in Cook Islands (60.1%, 52.6-67.6%) and Nauru (67.9%, 60.5-75.0%).Conclusions: Globally, the prevalence of overweight and obesity has increased since 1980, and the increase has accelerated. Although obesity increased in most countries, levels and trends varied substantially. These data on trends in overweight and obesity may be used to set targets for obesity prevalence as requested at the United Nations high-level meeting on Prevention and Control of NCDs. © 2012 Stevens et al.; licensee BioMed Central Ltd

National, regional, and global trends in body-mass index since 1980: Systematic analysis of health examination surveys and epidemiological studies with 960 country-years and 9·1 million participants

Excess bodyweight is a major public health concern. However, few worldwide comparative analyses of long-term trends of body-mass index (BMI) have been done, and none have used recent national health examination surveys. We estimated worldwide trends in population mean BMI. We estimated trends and their uncertainties of mean BMI for adults 20 years and older in 199 countries and territories. We obtained data from published and unpublished health examination surveys and epidemiological studies (960 country-years and 9·1 million participants). For each sex, we used a Bayesian hierarchical model to estimate mean BMI by age, country, and year, accounting for whether a study was nationally representative. Between 1980 and 2008, mean BMI worldwide increased by 0·4 kg/m2 per decade (95 uncertainty interval 0·2-0·6, posterior probability of being a true increase >0·999) for men and 0·5 kg/m2 per decade (0·3-0·7, posterior probability >0·999) for women. National BMI change for women ranged from non-significant decreases in 19 countries to increases of more than 2·0 kg/m2 per decade (posterior probabilities >0·99) in nine countries in Oceania. Male BMI increased in all but eight countries, by more than 2 kg/m2 per decade in Nauru and Cook Islands (posterior probabilities >0·999). Male and female BMIs in 2008 were highest in some Oceania countries, reaching 33·9 kg/m2 (32·8-35·0) for men and 35·0 kg/m2 (33·6-36·3) for women in Nauru. Female BMI was lowest in Bangladesh (20·5 kg/m2, 19·8-21·3) and male BMI in Democratic Republic of the Congo 19·9 kg/m2 (18·2-21·5), with BMI less than 21·5 kg/m2 for both sexes in a few countries in sub-Saharan Africa, and east, south, and southeast Asia. The USA had the highest BMI of high-income countries. In 2008, an estimated 1·46 billion adults (1·41-1·51 billion) worldwide had BMI of 25 kg/m2 or greater, of these 205 million men (193-217 million) and 297 million women (280-315 million) were obese. Globally, mean BMI has increased since 1980. The trends since 1980, and mean population BMI in 2008, varied substantially between nations. Interventions and policies that can curb or reverse the increase, and mitigate the health effects of high BMI by targeting its metabolic mediators, are needed in most countries.
