Sex differences in cardiometabolic risk factors, pharmacological treatment and risk factor control in type 2 diabetes: findings from the Dutch Diabetes Pearl cohort

Introduction Sex differences in cardiometabolic risk factors and their management in type 2 diabetes (T2D) have not been fully identified. Therefore, we aimed to examine differences in cardiometabolic risk factor levels, pharmacological treatment and achievement of risk factor control between women and men with T2D. Research design and methods Cross-sectional data from the Dutch Diabetes Pearl cohort were used (n=6637, 40% women). Linear and Poisson regression analyses were used to examine sex differences in cardiometabolic risk factor levels, treatment, and control. Results Compared with men, women had a significantly higher body mass index (BMI) (mean difference 1.79kg/ m2 (95% CI 1.49 to 2.08)), while no differences were found in hemoglobin A1c (HbA1c) and systolic blood pressure (SBP). Women had lower diastolic blood pressure (−1.94mm Hg (95% CI −2.44 to −1.43)), higher total cholesterol (TC

Heritability estimates for 361 blood metabolites across 40 genome-wide association studies

Metabolomics examines the small molecules involved in cellular metabolism. Approximately 50% of total phenotypic differences in metabolite levels is due to genetic variance, but heritability estimates differ across metabolite classes. We perform a review of all genome-wide association and (exome-) sequencing studies published between November 2008 and October 2018, and identify >800 class-specific metabolite loci associated with metabolite levels. In a twin-family cohort (N = 5117), these metabolite loci are leveraged to simultaneously estimate total heritability (h2 total), and the proportion of heritability captured by known metabolite loci (h2 Metabolite-hits) for 309 lipids and

Perspectives of obese children and their parents on lifestyle behavior change: a qualitative study

BACKGROUND: In order to improve and optimize future behavioral family lifestyle intervention programs, more information on the perceptions of obese children and their parents of these programs is needed. As such, the aim of this qualitative study is 1) to explore the expectations of obese children and their parents in relation to lifestyle interventions; 2) to identify barriers to making lifestyle changes that parents and children face within their social context (within the family, at school and amongst friends and peers) as well as the things that facilitate these changes and 3) to identify the needs of obese children and their parents in the context of a lifestyle intervention. METHODS: A qualitative study using semi-structured interviews was conducted. Interviewees were participants in a lifestyle intervention program in the Netherlands. RESULTS: Eighteen children (mean age 10 years) and 24 parents were interviewed. The respondents expected to lose weight by being physically active or by eating healthily. Parents struggled with adopting and adhering to new rules and the absence of support of family members. Children struggled with inconsistent parenting and a lack of support from their parents. Bullying experienced at school impeded the children in their ability to make the necessary changes. Support from peers, on the other hand, stimulated their progress. Parents identified the need for the general practitioner to discuss overweight in a non-offensive way and to show an interest in the process of weight loss. CONCLUSIONS: Participants in a lifestyle behavior intervention program benefit from parental support and help from their (extended) family, peers and friends. They would also profit from the sustained involvement of their general practitioner in assisting in the maintenance of lifestyle behavior changes.

Screening for sexual dissatisfaction among people with type 2 diabetes in primary care

Aims The identification and discussion of sexual care needs in people with type 2 diabetes mellitus (T2DM) in primary care is currently insufficient. The objective of this study was to determine the prevalence of sexual dissatisfaction, sexual problems and need for help by using a screening instrument among people with T2DM in primary care. Methods Data were collected in 45 general practices in the Netherlands from January 2015 to February 2016. The Brief Sexual Symptom Checklist (BSSC) was used to screen among 40–75 year old men and women. Results In total, 786 people with T2DM (66.5% men) were screened. The prevalence of sexual dissatisfaction was 36.6%, significantly higher among men than among women (41.1% vs. 27.8%). Sexually dissatisfied men most often reported erectile dysfunction (71.6%); for sexually dissatisfied women, low sexual desire (52.8%) and lubrication problems (45.8%) were most common. More than half of all dissatisfied people had a need for care (61.8%), significantly more men than women (66.8% vs. 47.2%). Conclusions One third of people with T2DM is sexually dissatisfied and more than half of these people report a need for help. The BSSC could be used a tool to proactively identify sexually dissatisfied people in primary care

The Epidemiology of Hip and Major Osteoporotic Fractures in a Dutch Population of Community-Dwelling Elderly : Implications for the Dutch FRAX (R) Algorithm

Background Incidence rates of non-hip major osteoporotic fractures (MOF) remain poorly characterized in the Netherlands. The Dutch FRAX (R) algorithm, which predicts 10-year probabilities of hip fracture and MOF (first of hip, humerus, forearm, clinical vertebral), therefore incorporates imputed MOF rates. Swedish incidence rate ratios for hip fracture to MOF (Malmo 1987-1996) were used to perform this imputation. However, equality of these ratios between countries is uncertain and recent evidence is scarce. Aims were to estimate incidence rates of hip fracture and MOF and to compare observed MOF rates to those predicted by the imputation method for the Netherlands. Methods Using hospitalisation and general practitioner records from the Dutch PHARMO Database Network (2002-2011) we calculated age-and-sex-specific and age-standardized incidence rates (IRs) of hip and other MOFs (humerus, forearm, clinical vertebral) and as used in FRAX (R). Observed MOF rates were compared to those predicted among community-dwelling individuals >= 50 years by the standardized incidence ratio (SIR; 95% CI). Results Age-standardized IRs (per 10,000 person-years) of MOF among men and women >= 50 years were 25.9 and 77.0, respectively. These numbers were 9.3 and 24.0 for hip fracture. Among women 55-84 years, observed MOF rates were significantly higher than predicted (SIR ranged between 1.12-1.50, depending on age). In men, the imputation method performed reasonable. Conclusion Observed MOF incidence was higher than predicted for community-dwelling women over a wide age-range, while it agreed reasonable for men. As miscalibration may influence treatment decisions, there is a need for confirmation of results in another data source. Until then, the Dutch FRAX1output should be interpreted with caution
