Association between sexual dysfunction and vitamin D in Swedish primary health care patients born in the Middle East and Sweden.

The present study investigated primary care patients and compared self-reported sexual health in Swedes and Middle Easterners; analysed differences within and between the groups and analysed differences in 25-hydroxyvitamin D [25(OH)D] levels between the groups. 522 patients responded to a health questionnaire that included items on sexual health: 225 Middle Easterners from Iran, Iraq, and Turkey and 297 Swedes. Logistic regression was used to calculate the odds ratio (OR). Middle Easterners reported less sexual dysfunction than Swedes, and 75.8% of them and 18.9% of Swedes presented a 25(OH)D of < 50 nmol/L. The crude OR for reporting sexual dysfunction was 70% higher in Swedes compared to Middle Easterners (OR 1.70, 95% CI 1.15-2.50). This OR remained significant after adjustment for age, gender, waist circumference, and reported sexual desire. However, the significance disappeared after additional adjustment for 25(OH)D. In both groups, more females than males reported insufficient sexual desire. More female Middle Easterners reported sex life dissatisfaction. More female Swedes reported sexual dysfunction. Vitamin D could explain an association between gender and sex life dissatisfaction in Middle Easterners, and age could explain an association between gender and sexual dysfunction in Swedes. Age, waist circumference, and 25(OH)D levels were significant covariates in the logistic regression models. Results from the present study suggest that 25(OH)D variation partly explains differences in sexual dysfunction between the groups and between genders within the groups. Vitamin D therapy should be investigated to determine if these results are clinically useful.

Fasting plasma glucose and serum 25-hydroxy vitamin D levels in individuals with Middle Eastern and Swedish descent.

Purpose: To determine fasting plasma glucose and serum 25-hydroxyvitamin D (s-25(OH)D) levels and associations between abnormal fasting plasma glucose levels and inadequate s-25(OH)D levels in individuals of Middle Eastern and Swedish descent. Methods: Observational study with individuals without a diabetes diagnosis, 54.5% of Swedish descent and 45.5% of Middle Eastern descent. In total, 830 participants from two primary healthcare centres in Flemingsberg and Jakobsberg, which are southern and northern suburbs, respectively, of Stockholm, Sweden were included in the study. Results: Prevalence of inadequate s-25(OH)D levels (at or below 50 nmol/L) was 67.2% among those of Middle Eastern descent and 20.5% among those of Swedish descent (P < 0.001). S-25(OH)D levels correlated weakly positively with fasting plasma glucose levels (ρ = 0.20, P = 0.002) in individuals of Middle Eastern descent. Being of Middle Eastern descent (OR 6.7, 95% CI 4.3-10.4) and having abnormal fasting plasma glucose (OR 1.8, 95% CI 1.2-2.9) were independent predictors of having inadequate s-25(OH)D levels. Conclusions: Healthcare in Sweden should consider testing fasting plasma glucose and s-25(OH)D levels, particularly in individuals of Middle Eastern descent. The unclear relationship between vitamin D and glucose levels warrants investigation.

Comparison of Framingham 10-year cardiovascular risks in Sweden- and foreign-born primary health care patients in Sweden.

BACKGROUND: The prevalence of cardiovascular disease around the world varies by ethnicity and region of birth. Immigrants living in Sweden may have a higher prevalence of cardiovascular diseases than native-born Swedes, but little is known about their actual cardiovascular risk. This study aimed to examine the relationship in Sweden between 10-year cardiovascular risk and birthplace. METHOD: This cross-sectional study was based on cardiovascular risk factor data obtained from the 4D Diabetes Project, a Programme 4D subproject in Sweden. Participants were recruited from two primary healthcare centres in Stockholm without a history of diabetes or pre-diabetes. The outcome variable was 10-year cardiovascular risk based on the calculation of a Framingham Risk Score with six risk factors: age, sex, LDL, HDL, BP, diabetes and smoking for each participant. Multiple linear regression was performed to generate ß-coefficients for the outcome. RESULTS: There was an average of 8.86% cardiovascular risk over 10 years in Sweden-born participants and a 5.45% 10-year risk in foreign-born, (P < 0.0001). Foreign-born participants were about 10 years younger (mean age 46 years vs. 56 years, P < 0.001), with a significantly higher proportion of smokers (23.9% vs. 13.7%; P = 0.001). To be born in Sweden (with parents born in Sweden) was significantly associated with a 10-year cardiovascular risk in the crude model (ß- coefficient = 3.40, 95% CI 2.59-4.22; P < 0.0001) and when adjusted for education and alcohol consumption (ß- coefficient = 2.70 95% CI 1.86-3.54; P < 0.0001). Regardless of the birthplace, 10-year cardiovascular risk was lower for those with higher education compared to those with less than 10 years of education. CONCLUSION: This study found a relationship between 10-year calculated cardiovascular risk and place of birth. Sweden-born participants had a higher association with 10-year cardiovascular risk than foreign-born participants. These results contradict previous reports of higher rates of CVD in residents of Middle-Eastern countries and Middle-Eastern immigrants living in Sweden.

Burning sensation in the feet and glycosylated haemoglobin levels in Swedish- and non-Swedish-born primary healthcare patients.

BACKGROUND: A painful burning sensation in the feet is a common problem. The most common cause is small fibre neuropathy, a type of peripheral neuropathy that is often a consequence of diabetes and prediabetes. AIM: To examine the association between a self-reported burning sensation in the feet and HbA1c levels in primary healthcare patients. METHODS: This study used data from patients in the 4D diabetes project in Swedish primary healthcare. The study population included 824 patients. Logistic regression was performed to study the association between the outcome and explanatory variables. RESULTS: A total of 24% of patients reported a burning sensation in the feet. This sensation was not associated with HbA1c levels. However, the probability of reporting a burning sensation was two times higher in non-Swedish-born than Swedish-born patients (OR, 2.31; 95% CI, 1.55-3.44) and higher in smokers than those who had never smoked, regardless of region of birth (OR, 1.69; 95% CI, 1.07-2.65). CONCLUSIONS: Our results do not support the hypothesis that a self-reported burning sensation in the feet is associated with HbA1c levels. Rather, they indicate a strong relationship between a burning sensation and region of birth, as well as between a burning sensation and smoking.

Extent of the association between self-rated health and place of birth: a cross-sectional study among people at high risk of developing pre-diabetes and diabetes in Sweden.

OBJECTIVE: The first aim was to determine the extent of the relationship between place of birth and self-rated health (SRH) in primary healthcare patients born outside Sweden and those born in Sweden. The second aim was to investigate whether socioeconomic and lifestyle factors explained any differences. SETTING: Two academic primary healthcare centres in Stockholm County, Sweden. PARTICIPANTS: 825 patients at high risk of developing pre-diabetes and diabetes, aged 18-74 years, attending academic healthcare centres in areas with large numbers of immigrants, 56.8% born abroad and 43.2% born in Sweden. Patients with a diagnosis of diabetes were excluded. Inclusion criteria were based on previous research showing that people born in Middle Eastern and Asian countries who live in Sweden have a high prevalence of and risk for diabetes. OUTCOME: SRH was dichotomised as optimal (very good/good) and suboptimal (fair/bad/very bad) and compared in those born outside Sweden and in Sweden. RESULTS: There was a statistically significant difference in the SRH of the two groups (p=0.008). Logistic regression analysis showed a crude OR for reduced SRH of 1.46 (95% CI 1.10 to 1.92) in patients born outside Sweden. After controlling for education, employment and marital status, the OR increased to 1.50 (95% CI 1.11 to 2.02). After controlling for physical activity and smoking, it decreased to 1.36 (95% CI 1.00 to 1.85). CONCLUSION: Socioeconomic and lifestyle factors influenced SRH. It could therefore be useful for clinicians to consider these factors when providing care for patients born outside Sweden and resettled in areas with large numbers of immigrants.

App-technology to increase physical activity among patients with diabetes type 2 - the DiaCert-study, a randomized controlled trial.

BACKGROUND: Physical activity can decrease the risk of complications related to diabetes type 2. Feasible and scalable strategies to implement support for a healthy lifestyle for patients in primary care are needed. The aim of the DiaCert-study is to evaluate a digital healthcare platform and the effect of a 12-week long smartphone-app physical activity intervention aiming at increasing physical activity (primary outcome) and improve levels of HbA1c (glycated hemoglobin), blood lipids, blood pressure, body composition, as well as other lifestyle factors and overall health in patients with diabetes type 2. METHODS/DESIGN: The DiaCert-study is a two-arm, randomized controlled trial that will include 250 patients with diabetes type 2. At baseline, participants are randomized 1:1 to intervention, i.e. use of the smartphone-app, during 12 weeks, or to a control group receiving only standard care. Physical activity and sedentary behavior, is objectively measured using the Actigraph GT3X. Biomarkers including HbA1c and blood lipids are measured in fasting blood samples. Anthropometrics include height, weight, waist circumference and body composition, and a number of lifestyle factors including sleep, diet, self-efficacy, and quality of life, are assessed through an extensive questionnaire. Measurements are made at baseline and at follow-up after 3, 6 and 12 months. DISCUSSION: Using new technology, is one way to bridge the gap between what patients need and what health care can offer. This study evaluates a new digital health care platform and will show if use of a smartphone-app to promote daily steps is an effective and feasible method to increase physical activity and improve clinical markers in patients with diabetes type 2.

Haemoglobin A1c as a screening tool for type 2 diabetes and prediabetes in populations of Swedish and Middle-East ancestry.

AIMS: To explore and compare sensitivity and specificity for HbA1c ≥48mmol/mol as a predictor for type 2 diabetes mellitus (T2DM) in two populations with different ethnicity and to examine the predictive value of two levels of HbA1c (≥42mmol/mol, ≥39mmol/mol) for prediabetes in these populations. METHODS: Four cohorts were examined with an oral glucose tolerance test. (1) The MEDIM Study (n=1991 individuals of Swedish and Iraqi ancestry); (2) The Skaraborg Project (n=1327 individuals of Swedish ancestry); (3) The 4-D study (n=424 individuals of Swedish, Iraqi and Turkish ancestry); (4) The Flemingsberg study (n=212 participants of Turkish ancestry). RESULTS: HbA1c ≥48mmol/mol had a sensitivity for T2DM of 31% and 25% respectively in individuals of Middle-East and Swedish ancestry. The positive and negative predictive value was high in both populations (70.3, 96.4 and 96.2, 97.6 respectively). Using HbA1c ≥42mmol/mol and ≥39mmol/mol as a predictor for prediabetes gave a sensitivity of 17% and 36% in individuals of Middle-East and 15% and 34% in individuals of Swedish ancestry. CONCLUSIONS: Even if HbA1c ≥48mmol/mol is a valuable diagnostic tool, it is a blunt and insensitive tool for screening and would exclude most people with T2DM, independent of ancestry and age. HbA1c is an inefficient way to detect individuals with prediabetes.

Prevalence of diabetes among immigrants in the Nordic countries.

Some immigrant groups in Europe show an increased prevalence of diabetes, e.g. South Asians in the UK and Moroccans and Turks in the Netherlands. This study aimed at reviewing the literature among immigrants in the Nordic countries. Search was performed primarily of Medline through PubMed, and secondarily of other databases and by using information from reference lists. Terms used were: "Diabetes Mellitus", "Immigrant", and "Nordic countries" or "Scandinavia" or "Denmark", "Finland", "Iceland", "Norway" or "Sweden". Altogether 17 articles on diabetes were found. Excess risk of diabetes was found in non-European immigrant groups, especially from the Middle East and South Asian regions, in some cases 10 times the risk of the indigenous population, with the highest relative risks among women. No excess risk was found among European immigrants, with the possible exception of Finnish women. Conflicting results were found in studies with a low number of diabetic cases, with a failure to show statistically significant excess risks among non-European groups. There were also some other methodological problems, e.g. low participation rate in population based clinical studies, and probable underestimation of known diabetes by self-report. A genetic sensitivity seems likely in the Middle East and South Asian groups, combined with lifestyle factors.

Self-reported anxiety, sleeping problems and pain among Turkish-born immigrants in Sweden.

OBJECTIVES: To study whether symptoms of self-reported anxiety, sleeping problems and severe pain are more common among Turkish-born immigrants in Sweden than among Swedes, and whether age and socio-economic status can explain this hypothesised difference. DESIGN: Two random samples were studied -- the Swedish National Board of Health and Welfare Immigrant Survey, and the Swedish Annual Level-of-Living Survey, both from 1996. A total of 526 Turkish-born immigrants in Sweden were compared with 2,854 Swedish controls, all aged between 27 and 60 years. Data were analysed by sex, in an age-adjusted model; and a full model also included age, education, marital status, employment and country of origin (logistic regression). RESULTS: In the full model, odds ratios were 2.12 (1.43-3.15) for anxiety, 2.60 (1.82-3.72) for sleeping problems, and 2.14 (1.50-3.05) for severe pain among Turkish-born men, and 2.44 (1.69-3.53) for anxiety, 3.01 (2.09-4.33) for sleeping problems, and 2.59 (1.80-3.71) for severe pain among Turkish-born women, using the Swedish controls as references. CONCLUSIONS: Being a Turkish-born immigrant in Sweden significantly increases the risks for self-reported anxiety, sleeping problems and severe pain, even after adjusting for age and socio-economic status (education, marital status and employment).
