Risk of venous thromboembolism in relation to high physical activity level in men over 27 year follow up.

Venous thromboembolism (VTE) is the third most common type of cardiovascular disease. An association between high level of physical activity (PA) and the onset of VTE has been found in some, but not all previous studies. We aim to study the association between PA-level and VTE in a cohort of men with updated data on PA levels at four occasions. We used data from the Uppsala Longitudinal Study of Adult Men (ULSAM) study initiated in 1970, a study of men at age 50 years (n = 2,294 at baseline) examined on leisure time PA by questionnaire and traditional cardiovascular risk factors. Examinations were repeated at ages 60, 70, and 77, and follow-up was completed after a median time of 33 years. Cox regression analysis with hazard ratios (HRs) using updated covariates for PA and risk factors was performed on the association of PA levels with incident VTE, with adjustments for established cardiovascular risk factors (systolic blood pressure, LDL- and HDL-cholesterol, BMI, diabetes, and smoking). Totally 186 men experienced a VTE during follow-up of 68,263 person-years at risk. Individuals with the highest PA level had an increased relative risk of VTE, adjusted HR, 2.22 (95% CI 1.05-4.67), when compared to individuals with the lowest level of PA. In this cohort of men with a follow-up of 27 years, the risk of VTE was increased at the highest PA level. Findings indicate that there could be an increased VTE risk with higher PA level including strenuous activities.

Osteoporotic fractures in second-generation immigrants and Swedish natives.

In this national study of osteoporotic fractures in second-generation immigrants in Sweden, we found a similar risk of osteoporotic fractures in general compared to Swedish natives, which suggests that environmental factors are important for the high risk of osteoporotic fractures in Nordic countries. INTRODUCTION: Second generation immigrants may have a similar environment as individuals with two native-born parents. These individuals may be of interest to study concerning whether environmental or hereditary factors could be mostly associated to the risk of osteoporotic fractures. The aim of this study was to analyse the risk of osteoporotic fractures in second-generation immigrants compared to Swedish natives. METHODS: This was a nationwide study of individuals aged 50 years of age and older (N = 1,377,035; 691,750 men and 685,285 women). Osteoporotic fractures were defined as at least one registered diagnosis of fractures in the hip, humerus, forearm or vertebrae, in the National Patient Register between January 1, 1998, and December 31, 2012. Cox regression analysis was used to estimate the relative risk (hazard ratios (HR) with 95% confidence intervals (CI)) of incident osteoporotic fractures in second generation immigrants compared to Swedish natives. The Cox regression models were adjusted for age, comorbidities and for sociodemographic status. RESULTS: A total of 114,505 osteoporotic fractures were registered, 109,622 (8.4%) were among individuals with Swedish-born parents and 4883 (7.5%) among those with foreign-born parents, with distal forearm fractures dominating in general (44.9%). Fully adjusted HRs (95% CI) were for all immigrants 0.95 (95% CI, 0.91-0.99), for men 0.96 (95% CI, 0.89-1.04) and for women 0.95 (95% CI, 0.90-1.00). CONCLUSIONS: We observed a similar risk of osteoporotic fractures among second-generation immigrants as in Swedish natives, which suggests that environmental factors are important for osteoporotic fractures.

Osteoporotic fractures among foreign-born individuals: a national Swedish study.

In this national study of osteoporotic fractures in foreign-born individuals, we found a lower risk of osteoporotic fractures in general among foreign-born individuals compared with Swedish-born, especially in immigrants from southern Europe. A higher risk was found among some groups, i.e. men and women from Bosnia and Iraq and men from Lebanon. INTRODUCTION: The aim of this study was to analyse risk of osteoporotic fractures in foreign-born individuals compared with Swedish-born individuals. METHODS: This was a nationwide study of individuals 50 years of age and older (N = 2,775,736). Osteoporotic fractures were defined as at least one registered diagnosis of fractures in the hip, humerus, forearm or vertebrae, in the National Patient Register between January 1, 1998, and December 31, 2012. Cox regression analysis was used to estimate the relative risk (hazard ratios (HR) with 99% confidence intervals (CI)) of incident osteoporotic fractures in foreign-born compared with Swedish-born individuals. The Cox regression models were stratified by sex and adjusted for age, comorbidities and sociodemographic status. RESULTS: A total of 362,899 osteoporotic fractures were registered (96,847 among men and 266,052 among women), with hip fractures dominating (54.0% among men, 42.6% among women). Fully adjusted HRs (99% CI) were for all immigrant men 0.75 (99% CI, 0.73-0.78) and women 0.83 (99% CI, 0.81-0.84), with significantly lower HRs among most groups but with higher HRs in certain countries. For the specific fractures, higher HRs were found for lower forearm fractures for men from Asia and for vertebral fractures among women from Asia. CONCLUSIONS: We observed a generally lower risk of osteoporotic fractures among first-generation immigrants, with few exceptions.

The risk of venous thromboembolism and physical activity level, especially high level: a systematic review.

Venous thromboembolism (VTE) is the third most common cause of cardiovascular disease. Connection between high level of physical activity (PA) and the onset of VTE is unknown. We searched the literature on the possible association between PA level, especially high levels, and the risk of VTE. A systematic review was carried out to identify relevant articles on the relation between PA level and VTE. The initial search was conducted together with the Karolinska Institutet University Library in February 2018, with follow-up searches after that. In total, 4383 records were found and then screened for exclusion of duplicates and articles outside the area of interest. In total, 16 articles with data on 3 or more levels of PA were included. Of these, 12 were cohort and 4 were case-control studies. Totally 13 studies aimed at investigating VTE cases primarily, while three studies had other primary outcomes. Of the 16 studies, five found a U-shaped association between PA level and VTE risk, although non-significant in three of them. Two articles described an association between a more intense physical activity and a higher risk of VTE, which was significant in one. Nine studies found associations between increasing PA levels and a decreasing VTE risk. Available literature provides diverging results as to the association between high levels of PA and the risk of venous thromboembolism, but with several studies showing an association. Further research is warranted to clarify the relationship between high level PA and VTE.

Epilepsy in second-generation immigrants: a cohort study of all children up to 18 years of age in Sweden.

BACKGROUND AND PURPOSE: Our purpose was to study the association between country of birth and incident epilepsy in second-generation immigrants in Sweden. METHODS: The study population included all children (n = 4 023 149) aged up to 18 years in Sweden. Epilepsy was defined as at least one registered diagnosis of epilepsy in the National Patient Register. The incidence of epilepsy, using individuals with Swedish-born parents as referents, was assessed by Cox regression, expressed in hazard ratios (HRs) and 95% confidence interval (95% CI). All models were stratified by sex and adjusted for age, geographical residence in Sweden, educational level, marital status, neighbourhood socioeconomic status and comorbid conditions, also using data from the Total Population Register. RESULTS: A total of 26 310 individuals had a registered epilepsy event, i.e. 6.5/1000 (6.6/1000 amongst boys and 6.3/1000 amongst girls). After adjustment, the risk of epilepsy was lower than in children of Swedish-born parents. Amongst girls the significant HR was 0.85 (95% CI 0.81-0.88), but in boys only when adjusting also for comorbidity (HR 0.96, 95% CI 0.92-0.99). Amongst specific immigrant groups, a higher incidence of epilepsy was observed amongst boys with parents from Turkey and Africa, but not when adjusting for comorbidity, and a lower risk was observed in many other groups (boys with parents from Latvia, girls with parents from Finland, Iceland, Southern Europe, countries from the former Yugoslavia, and Asia). CONCLUSION: The risk of epilepsy was lower in second-generation immigrant children compared to children with Swedish-born parents, but with substantial differences between different immigrant groups.

The use of anthropometric measures in the prediction of incident gout: results from a Swedish community-based cohort study.

Objectives: To study associations between different anthropometric measures and incident gout, and to find the best predictive measure. Method: We used the baseline investigation from the Malmö Diet and Cancer study, excluding cases of prevalent gout (n = 28 081). Cox regression for each anthropometric measurement was calculated per standard deviation increment for men and women, with hazard ratios (HRs) and 95% confidence intervals (CIs), using a hospital diagnosis of incident gout (M10) during follow-up as the outcome. Incremental C-statistics for each anthropometric measure were used to determine the measure with the best predictive capacity, in models adjusted for age, socio-economic data, lifestyle factors, comorbidities, and antihypertensive medications. Results: The study population included 11 049 men and 17 032 women, with 633 incident gout cases, 393 in men (3.6%) and 240 in women (1.4%). For both men and women, the five anthropometric measurements with highest C-statistics were weight, body mass index (BMI), waist circumference (WC), hip circumference, and waist-to-height ratio; in men, the measurement with the highest C-statistic was BMI (0.7361; fully adjusted HR 1.52, 95% CI 1.39-1.68), and in women WC (0.8085; fully adjusted HR 1.62, 95% CI 1.46-1.81). The increment in C-statistic with anthropometric measures was good, around 0.035. Waist-to-hip ratio, waist-to-hip-to-height ratio, body fat percentages, and especially A Body Shape Index had lower C-statistics. Conclusions: Both BMI and WC showed good predictive ability for incident gout. The clinically used cut-offs for BMI and WC appeared to be relevant in the assessment of increased risk of gout.

Comorbidities, risk factors and outcomes in patients with heart failure and an ejection fraction of more than or equal to 40% in primary care- and hospital care-based outpatient clinics.

OBJECTIVE: The aim of this study is to describe patients with heart failure and an ejection fraction (EF) of more than or equal to 40%, managed in both Primary- and Hospital based outpatient clinics separately with their prognosis, comorbidities and risk factors. Further to compare the heart failure medication in the two groups. DESIGN: We used the prospective Swedish Heart Failure Registry to include 9654 out-patients who had HF and EF ≥40%, 1802 patients were registered in primary care and 7852 in hospital care. Descriptive statistical tests were used to analyze base line characteristics in the two groups and multivariate logistic regression analysis to assess mortality rate in the groups separately. SETTING: The prospective Swedish Heart Failure Registry. SUBJECTS: Patients with heart failure and an ejection fraction (EF) of more than or equal to 40%. MAIN OUTCOME MEASURES: Comorbidities, risk factors and mortality. RESULTS: Mean-age was 77.5 (primary care) and 70.3 years (hospital care) p < 0.0001, 46.7 vs. 36.3% women respectively (p < 0.0001) and EF ≥50% 26.1 vs. 13.4% (p < 0.0001). Co-morbidities were common in both groups (97.2% vs. 92.3%), the primary care group having more atrial fibrillation, hypertension, ischemic heart disease and COPD. According to the multivariate logistic regression analysis smoking, COPD and diabetes were the most important independent risk factors in the primary care group and valvular disease in the hospital care group. All-cause mortality during mean follow-up of almost 4 years was 31.5% in primary care and 27.8% in hospital care. One year-mortality rates were 7.8%, and 7.0% respectively. CONCLUSION: Any co-morbidity was noted in 97% of the HF-patients with an EF of more than or equal to 40% managed at primary care based out-patient clinics and these patients had partly other independent risk factors than those patients managed in hospital care based outpatients clinics. Our results indicate that more attention should be payed to manage COPD in the primary care group. KEY POINTS 97% of heart failure patients with an ejection fraction of more than or equal to 40% managed at primary care based out-patient clinics had any comorbidity. Patients in primary care had partly other independent risk factors than those in hospital care. All-cause mortality during mean follow-up of almost 4 years was higher in primary care compared to hospital care. In matched HF-patients RAS-antagonists, beta-blockers as well as the combination of the two drugs were more seldom prescribed when managed in primary care compared with hospital care.

High prevalence of diabetes mellitus, hypertension and obesity among persons with a recorded diagnosis of intellectual disability or autism spectrum disorder.

BACKGROUND: Obesity and lack of physical activity are frequently reported in persons with intellectual disability (ID) or autism spectrum disorder (ASD). We hypothesised a higher prevalence of diabetes and hypertension in this population. METHOD: We used administrative data for all primary and specialist outpatient and inpatient healthcare consultations for people with at least one recorded diagnosis of diabetes mellitus, hypertension or obesity from 1998 to 2015. Data were drawn from the central administrative database for Stockholm County, Sweden. It was not possible to separate data for type 1 and type 2 diabetes. We stratified 26 988 individuals with IDs or ASD into three groups, with Down syndrome treated separately, and compared these groups with 1 996 140 people from the general population. RESULTS: Compared with the general population, men and women with ID/ASD had 1.6-3.4-fold higher age-adjusted odds of having a registered diagnosis of obesity or diabetes mellitus, with the exception of diabetes among men with Down syndrome. A registered diagnosis of hypertension was only more common among men with ID/ASD than in the general population. CONCLUSIONS: Diabetes and blood pressure health screening, along with efforts to prevent development of obesity already in childhood, are necessary for individuals with IDs and ASD. We believe that there is a need for adapted community-based health promotion programmes to ensure more equitable health for these populations.

The use of a Swedish telephone medical advice service by the elderly - a population-based study.

OBJECTIVE: The present study aimed to describe contact made by the elderly to Sweden's nationwide medical helpline, Healthcare Guide 1177 by Phone (HGP). Other objectives were to study potential gender differences and the association between different HGP referral levels and acute visits to hospital-based emergency departments and acute visits to primary care centres. DESIGN: De-identified data from recorded calls to HGP was extracted for analysis (n = 7477 for the oldest age group). Information about acute visits to emergency departments and to primary care reception was extracted from the patient administration system. SETTING: Västerbotten County, Sweden. SUBJECTS: Patients over 80 years. MAIN OUTCOME MEASURES: Calling and visiting frequencies for different age groups as well as reasons for contact and individual recommendations. RESULTS: The utilisation rate of the telephone advice service for the oldest age group was high, with an incidence rate of 533 per 1000 person-years. Women had a 1.17 times higher incidence rate compared with men. The most common reason for contact was drug-related questions (17% of all contacts). Calls that were recommended to care by a medical specialist correlated with total emergency department visits (r = 0.30, p < 0.05) and calls that were given advice correlated with acute primary healthcare visits (r = 0.38, p = 0.005). CONCLUSION: The high utilisation of the telephone advice service by the elderly gives the telephone advice service a unique ability to function as a gatekeeper to further healthcare. Our data suggest that with the telephone advice service's present guidelines, a significant proportion of all calls are being directed to further medical help. The high frequency of drug-related questions raises concerns about the elderly's medication regimens. Key points Patients over 80 years of age had a high utilisation of the telephone medical advice service compared with other age groups. Drug-related questions were the most common reason for contact. A significant proportion of all calls made resulted in further heatlhcare contacts.

Low fructosamine and mortality - A long term follow-up of 215,011 non-diabetic subjects in the Swedish AMORIS study.

BACKGROUND AND AIMS: Both high and low fasting glucose has been associated with an increased mortality among individuals without diabetes. This J-shaped association has also been shown for HbA1c in relation to all-cause mortality. High fructosamine is associated with increased mortality. In this study we aim to evaluate if low fructosamine is also associated with increased mortality in non-diabetic subjects. METHODS AND RESULTS: We included 215,011 subjects from the AMORIS cohort undergoing occupational health screening or primary care in Stockholm, Sweden. Cause specific mortality was obtained from the Swedish Cause-of-Death Register by record linkage. Hazard ratios for the lowest decile of fructosamine were estimated by Cox regression for all-cause (n = 41,388 deaths) and cause-specific mortality during 25 years of follow-up. We observed gradually increased mortality with lower fructosamine in a large segment of the population. In the lowest decile of fructosamine the sex, age, social class and calendar adjusted hazard ratio was 1.20 (95% CI; 1.18-1.27) compared to deciles 2-9. This increased mortality was attenuated after adjustment for six other biomarkers (HR = 1.11 (95% CI; 1.07-1.15)). Haptoglobin, an indicator of chronic inflammation, made the greatest difference in the point estimate. In sensitivity analyses we found an association between low fructosamine and smoking and adjustment for smoking further attenuated the association between low fructosamine and mortality. CONCLUSION: Low levels of fructosamine in individuals without diabetes were found to be associated with increased mortality. Smoking and chronic inflammation seem to at least partially explain this association but an independent contribution by low fructosamine cannot be excluded.

Prevalence and incidence of diabetes mellitus: a nationwide population-based pharmaco-epidemiological study in Sweden.

AIM: To investigate the changes in prevalence and incidence of pharmacologically and non-pharmacologically treated diabetes in Sweden during 2005 to 2013. METHODS: We obtained data on gender, date of birth and pharmacologically and non-pharmacologically treated diabetes from national registers for all Swedish residents. RESULTS: During the study period a total of 240 871 new cases of pharmacologically treated diabetes was found. The age-standardized incidence during the follow-up was 4.34 and 3.16 per 1000 individuals in men and women, respectively. A decreasing time trend in incidence for men of 0.6% per year (0.994, 95% CI 0.989-0.999) and for women of 0.7% per year (0.993, 95% CI 0.986-0.999) was observed. The age-standardized prevalence increased from 41.9 and 29.9 per 1000 in 2005/2006 to 50.8 and 34.6 in 2012/2013 in men and women, respectively. This corresponds to an annually increasing time trend for both men (1.024, 95% CI 1.022-1.027) and women (1.019, 95% CI 1.016-1.021). The total age-standardized prevalence of pharmacologically and non-pharmacologically treated diabetes (2012) was 46.9 per 1000 (55.6 for men and 38.8 for women). This corresponds to an annually increasing time trend (2010-2012) for both men (1.017, 95% CI 1.013-1.021) and women (1.012, 95% CI 1.008-1.016). CONCLUSIONS: The prevalence of pharmacologically treated diabetes increased moderately during 8 years of follow-up, while the incidence decreased modestly. This is in contrast to the results reported by most other studies. The total prevalence of diabetes (both pharmacologically and non-pharmacologically treated) in Sweden is relatively low, from a global viewpoint.

Nurse-led empowerment strategies for patients with hypertension: a questionnaire survey.

BACKGROUND: Hypertension is common and may lead to cerebrovascular and cardiovascular events and mortality. District nurses frequently encounter patients requiring blood pressure monitoring, lifestyle counsel and support. Empowerment as a method enables patients to both increase their control over their health and improve it. AIM: This study aims to describe the effects of the counsel and support from district nurses to patients with hypertension. METHODS: A randomized controlled intervention trial. Questionnaires were answered by patients with hypertension before and after the intervention comprising district nurses' counsel and support based upon empowerment. A specially developed card for blood pressure monitoring was also used. RESULTS: Blood pressure decreased in intervention and the control groups. The intervention group experienced significantly improved health, with better emotional and physical health, and reduced stress. Living habits did not change significantly in either group. Satisfaction with knowledge of hypertension increased significantly in both groups. The intervention group reported that their care was based upon their health needs. LIMITATIONS: Conducting large multi-centre studies with long follow-ups is complicated and results sometimes have a tendency to decline with time. A shorter follow-up might have shown a greater difference between the groups. CONCLUSION: Nursing interventions through district nurses' counsel and support with empowerment improved patients' health. More research is needed to evaluate nursing interventions' effect on hypertension. IMPLICATIONS FOR NURSING AND HEALTH POLICY: This study highlighted that district nurses' counsel and support increased patients' health and decreased stress by focusing on empowerment.

Effects of Nordic walking on cardiovascular risk factors in overweight individuals with type 2 diabetes, impaired or normal glucose tolerance.

BACKGROUND: Physical activity remains a valuable prevention for metabolic disease. The effects of Nordic walking on cardiovascular risk factors were determined in overweight individuals with normal or disturbed glucose regulation. METHODS: We included 213 individuals, aged 60 ± 5.3 years and with body mass index (BMI) of 30.2 ± 3.8 kg/m(2); of these, 128 had normal glucose tolerance (NGT), 35 had impaired glucose tolerance (IGT) and 50 had type 2 diabetes mellitus (T2DM). Participants were randomized to unaltered physical activity or to 5 h per week of Nordic walking with poles, for a 4-month period. Dietary habits were unaltered. BMI, waist circumference, blood pressure, glucose tolerance, clinical chemistry, maximal oxygen uptake (peak VO(2)) and self-reported physical activity (questionnaire) were assessed at the time of inclusion and after 4 months. The participants in the exercise-intervention group kept a walking diary. RESULTS: In the NGT exercise group, self-reported physical activity increased markedly, and body weight (-2.0 ± 3.8 kg), BMI (-0.8 ± 1.4 kg/m(2)) and waist circumference (-4.9 ± 4.4 cm) (mean ± SD) decreased. Exercise power output (12.9 ± 9.9 W) and peak VO(2) (2.7 ± 2.8 mL/kg/min) increased in the IGT exercise group. More cardiovascular risk factors were improved after exercise intervention in people with NGT compared with those with IGT or T2DM. Exercise capacity improved significantly in all three groups of participants who reported at least 80% compliance with the scheduled exercise. CONCLUSIONS: Nordic walking improved anthropometric measurements and exercise capacity. However, unsupervised Nordic walking may not provide a sufficient increase in exercise intensity to achieve ultimate health-promoting benefits on the cardiovascular parameters assessed in this study, particularly for those with disturbed glucose regulation.

Health effects of reduced occupational sedentary behaviour in type 2 diabetes using a mobile health intervention: a study protocol for a 12-month randomized controlled trial-the ROSEBUD study.

BACKGROUND: Short-term trials conducted in adults with type 2 diabetes mellitus (T2DM) showed that reducing sedentary behaviour by performing regular short bouts of light-intensity physical activity enhances health. Moreover, support for reducing sedentary behaviour may be provided at a low cost via mobile health technology (mHealth). There are a wide range of mHealth solutions available including SMS text message reminders and activity trackers that monitor the physical activity level and notify the user of prolonged sitting periods. The aim of this study is to evaluate the effects of a mHealth intervention on sedentary behaviour and physical activity and the associated changes in health in adults with T2DM. METHODS: A dual-arm, 12-month, randomized controlled trial (RCT) will be conducted within a nationwide Swedish collaboration for diabetes research in primary health care. Individuals with T2DM (n = 142) and mainly sedentary work will be recruited across primary health care centres in five regions in Sweden. Participants will be randomized (1:1) into two groups. A mHealth intervention group who will receive an activity tracker wristband (Garmin Vivofit4), regular SMS text message reminders, and counselling with a diabetes specialist nurse, or a comparator group who will receive counselling with a diabetes specialist nurse only. The primary outcomes are device-measured total sitting time and total number of steps (activPAL3). The secondary outcomes are fatigue, health-related quality of life and musculoskeletal problems (self-reported questionnaires), number of sick leave days (diaries), diabetes medications (clinical record review) and cardiometabolic biomarkers including waist circumference, mean blood pressure, HbA1c, HDL-cholesterol and triglycerides. DISCUSSION: Successful interventions to increase physical activity among those with T2DM have been costly and long-term effectiveness remains uncertain. The use of mHealth technologies such as activity trackers and SMS text reminders may increase awareness of prolonged sedentary behaviour and encourage increase in regular physical activity. mHealth may, therefore, provide a valuable and novel tool to improve health outcomes and clinical management in those with T2DM. This 12-month RCT will evaluate longer-term effects of a mHealth intervention suitable for real-world primary health care settings. TRIAL REGISTRATION: ClinicalTrials.gov NCT04219800 .

Effects of Nordic walking on health-related quality of life in overweight individuals with type 2 diabetes mellitus, impaired or normal glucose tolerance.

AIMS: To assess the effects of 4 months of increased physical activity on health-related quality of life in overweight individuals with Type 2 diabetes mellitus, normal or impaired glucose tolerance. METHODS: We included 212 individuals without severe physical or cardiovascular impairments aged 61 (57-64) years, with BMI of 29 (27.5-32) kg/m². Numbers are median (25th-75th percentile). Subjects were stratified based on normal glucose tolerance (n = 128), impaired glucose tolerance (n = 34) or Type 2 diabetes mellitus (n = 50). They were randomized into either a control group (n= 125), who maintained unaltered habitual lifestyle, or an exercise intervention group (n = 87), who were directed to engage in Nordic walking with walking poles, 5 h per week over 4 months. Self-reported physical activity and health-related quality of life was assessed at the time of inclusion and after 4 months. RESULTS: Baseline health-related quality of life of this study cohort was similar to, or better than, an age- and sex-matched Swedish population sample, for 12 of 13 scales. Quality of sleep and BMI were improved for participants with normal glucose tolerance after 4 months of Nordic walking, with little or no musculoskeletal pain as compared with control subjects. No correlation was evident between improved quality of sleep and improved BMI. CONCLUSIONS: Quality of sleep improved in the group with normal glucose tolerance following 4 months of Nordic walking. BMI reduction did not account for this improvement. Nordic walking can be introduced in a primary health care setting as a low-cost mode of exercise that promotes weight loss and improved health satisfaction.

Prevalence of blood lipid disturbances in Swedish and foreign-born 60-year-old men and women in Stockholm, Sweden.

BACKGROUND AND AIMS: Some immigrant groups in Sweden show a higher incidence of cardiovascular diseases, especially coronary heart disease. There is a lack of data of pattern of blood lipids among these. The aim of this study was to estimate the prevalence of dyslipidaemia in men and women of foreign-born origin compared to Swedish-born. METHODS AND RESULTS: A cross-sectional study of a random sample of the population in Stockholm County, Sweden, with total of 4228 60-year-old men and women. Medical, lifestyle and socio-economic data were collected by questionnaires, and anthropometric and laboratory data through medical examination. Outcomes were odds ratios (OR) with 95% confidence interval (95% CI) for dyslipidaemia in different groups, with Swedish-born as reference group, with adjustment for anthropometric, medical, lifestyle and socio-economic factors. Among non-European immigrants, the fully adjusted OR of high cholesterol was 0.57 (95% CI 0.37-0.88), of high LDL-cholesterol was 0.62 (95% CI 0.40-0.96), and of low HDL-cholesterol was 2.06 (95% CI 1.35-3.15). When only adjusting for sex, Finnish-born and non-European immigrants showed higher risk of high triglycerides, OR 1.31 (95% CI 1.01-1.71) and OR 1.98 (95% CI 1.34-2.93), respectively, and of high apoB/apoA-I ratio, OR 1.29 (95% CI 1.00-1.66) and OR 1.57 (95% CI 1.06-2.33), respectively. CONCLUSION: The finding of blood lipid disturbances among immigrants in this study partly explain the higher cardiovascular morbidity shown in previous studies. Non-European immigrants showed a different lipid pattern, with lower HDL-cholesterol, which could possibly be of genetic background.

Daily energy expenditure and cardiovascular risk in Masai, rural and urban Bantu Tanzanians.

BACKGROUND: Several studies have revealed that the Masai, pastoralists in Tanzania, have low rates of coronary heart disease despite a diet high in saturated fat. It has also been suggested that they may be genetically protected. Recent studies detailing other potential protective factors, however, are lacking. METHODS: A cross-sectional investigation of 985 Tanzanian men and women (130 Masai, 371 rural Bantu and 484 urban Bantu) with mean age of 46 (9.3) years. Anthropometric measures, blood pressure, serum lipids, and the reported dietary pattern and physical activity level were assessed. RESULTS: 82% of Masai subjects reported a high fat/low carbohydrate intake, whereas 77% of the rural Bantu subjects reported a low fat/high carbohydrate intake, while a high fat/high carbohydrate intake was the main dietary pattern of the urban Bantu group as, reported by 55%. The most conspicuous finding for the Masai was the extremely high energy expenditure, corresponding to 2565 kcal/day over basal requirements, compared with 1500 kcal/day in the rural and 891 kcal/day for the urban Bantu. Mean body mass index among the Masai was lower than the rural and urban Bantu. Mean systolic blood pressure of the Masai was also lower compared with their rural and urban Bantu counterparts. The Masai revealed a favourable lipid profile. CONCLUSION: The potentially atherogenic diet among the Masai was not reflected in serum lipids and was offset probably by very high energy expenditure levels and low body weight.

TNFR1 is associated with short-term mortality in patients with diabetes and acute dyspnea seeking care at the emergency department.

BACKGROUND: Circulating levels of TNF alpha receptor 1 (TNFR1) and 2 (TNFR2) are associated with increased long-term mortality and impaired kidney function. AIM: To study association between circulating levels of TNFR1 and TNFR2 and short-term mortality in patients with diabetes and dyspnea. POPULATION AND METHODS: Patients aged ≥ 18 years seeking at emergency department (ED) during daytime on weekdays between December 2013 and July 2018, with diabetes and acute dyspnea, identified at the triage process, were included. Participants (n = 291) were triaged according to Medical Emergency Triage and Treatment System-Adult score, and blood samples were collected. Association between TNFR1 and TNFR2, respectively, and 90-day mortality were estimated by Cox regression models adjusted for age, sex, BMI, creatinine and CRP. RESULTS: Univariate models showed significant associations between TNFR1 and TNFR2, respectively, and CRP, age and creatinine. TNFR1 and TNFR2 tended to be elevated in patients with the highest triage level, compared to patients with lower triage levels (ns). In longitudinal analyses, TNFR1 but not TNFR2 was associated with increased short-term mortality, HR adjusted for age, BMI and creatinine 1.43 (95% CI 1.07-1.91), but not in the model also adjusted for CRP, HR 1.29 (95% CI 0.94-1.77). In secondary analysis for quartile 4 versus quartiles 1-3 of TNFR1, corresponding HRs were 2.46 (95% CI 1.27-5.15) and 2.21 (95% CI 1.07-2.56). CONCLUSIONS: We found a trend for the association between circulating TNFR1 levels and short-term mortality in patients with diabetes and acute dyspnea at the ED, possibly suggesting an inflammatory pathway for the association.

The association between BMI value and long-term mortality.

OBJECTIVES: To study total mortality in different categories of BMI values, with adjustments for important covariates in a population-based 26-year mortality follow-up. Special interest will be given to gender differences and low BMI values. METHODS: From a stratified sample in 1969 of 32 185 individuals aged 18-64 years from Stockholm County, 2422 underwent a health examination, with complete data obtained for 1020 subjects. BMI was classified as underweight (<20), normal (20-24.9), overweight (25-29.9) or obesity (> or =30). Participants were followed up in the National Cause of Death Register until the end of 1996. Multivariate analysis was performed by Cox regression for men and women separately, with different models, with step-wise adjustment for age, care need category, heart rate, hypertension, blood glucose, alcohol intake and smoking, with hazard ratios (HR) and 95% confidence interval (CI) and with normal weight as reference. RESULTS: Among men, the age-adjusted HR was 1.68 (95% CI 1.10-2.57) for underweight and 1.62 (95% CI 1.08-2.43) for obesity, and among women it was 0.93 (95% CI 0.58-1.51) for underweight and 1.88 (95% CI 1.26-2.82) for obesity. In men, the significantly increased mortality remained when also adjusting for care need category, but not when adjusting for other factors, whereas the opposite was found regarding obesity. For women, underweight was significantly associated with decreased mortality when adjusting for smoking and for all factors together, whereas obesity was associated with increased mortality when adjusting for the different factors except for all factors together. CONCLUSIONS: Underweight was associated with higher mortality among men, but not when adjusting for covariates, whereas underweight was associated with lower mortality among women when adjusting for smoking.
