Development and feasibility of a conceptual model for planning individualised physical exercise training ( I PET) for older adults: a cross-sectional study

Objective: Older adults constitute a heterogeneous group, and the focus of the individual physical exercise is often subject to the reasoning and experience of health professionals or exercise physiologists who prescribe them. Thus, this is the first effort to explicitly conceptualise the planning of individualised physical exercise training (IPET) for older adults in an outpatient setting and investigate individual exercise preferences. Design: The concept of IPET was developed by researchers, exercise physiologists and health professionals from a real-life outpatient setting using an iterative approach. Health indicators assessing aerobic capacity, strength, balance and musculoskeletal pain/discomfort sites form the basis of physical exercise recommendations. A cross-sectional study was conducted to assess the basis of implementing IPET. Setting: Outpatient setting. Participants: We included 115 older adults (70 females) from an outpatient setting with a median age of 74 years. Outcome measures: Health indicators assessing aerobic capacity, strength, balance and musculoskeletal pain/discomfort sites were collected and informed the concept of IPET that structures exercise programmes based on the individual citizen’s needs and physical exercise preferences. Exceeding a health indicator cut-point results in exercise content mitigating the risk associated with the health indicator. Results: We included 115 older adults (70 females) from an outpatient setting median age of 74 years. Approximately two-thirds of participants exceeded at least one health indicator cut-point for aerobic training. One-third of the participants exceeded the cut-point for upper extremity strength, and almost all participants >99% exceeded the cut-point for lower extremity strength. Approximately two-thirds of the participants exceeded the cut-point for functional/balance training. The most prevalent site of musculoskeletal pain was the lower extremities. Eight of 20 training combinations were used, clustering the 115 participants primarily in three main training combinations. Discussion: This study shows that older adults vary in physical functioning, indicating that exercise preferences and rehabilitation needs are individual. Trial registration number: NCT04862481

Development and Validation of a Vitamin D Status Prediction Model in Danish Pregnant Women: A Study of the Danish National Birth Cohort

Vitamin D has been hypothesized to reduce risk of pregnancy complications such as preeclampsia, gestational diabetes mellitus, and preterm delivery. However, many of these outcomes are rare and require a large sample size to study, representing a challenge for cohorts with a limited number of preserved samples. The aims of this study were to (1) identify predictors of serum 25-hydroxy-vitamin D (25(OH)D) among pregnant women in a subsample (N = 1494) of the Danish National Birth Cohort (DNBC) and (2) develop and validate a score predicting 25(OH)D-status in order to explore associations between vitamin D and maternal and offspring health outcomes in the DNBC. In our study sample, 42.3% of the population had deficient levels of vitamin D (<50 nmol/L 25(OH)D) and average levels of 25(OH)D-status were 56.7(s.d. 24.6) nmol/L. A prediction model consisting of intake of vitamin D from diet and supplements, outdoor physical activity, tanning bed use, smoking, and month of blood draw explained 40.1% of the variance in 25(OH)D and mean measured 25(OH)D-level increased linearly by decile of predicted 25(OH)D-score. In total 32.2% of the women were placed in the same quintile by both measured and predicted 25(OH)D-values and 69.9% were placed in the same or adjacent quintile by both methods. Cohen's weighted kappa coefficient (Κ = 0.3) reflected fair agreement between measured 25(OH)D-levels and predicted 25(OH)D-score. These results are comparable to other settings in which vitamin D scores have shown similar associations with disease outcomes as measured 25(OH)D-levels. Our findings suggest that predicted 25(OH)D-scores may be a useful alternative to measured 25(OH)D for examining associations between vitamin D and disease outcomes in the DNBC cohort, but cannot substitute for measured 25(OH)D-levels for estimates of prevalence

Health and wellbeing in refugee families from Syria resettled in Denmark

Aims: The aim was to evaluate self-reported health status and wellbeing in a well-defined group of refugee families from Syria 2–4 years after resettlement in Denmark, and, where possible, compare it with a Danish reference population. The purpose was to determine the need for specialized health care to resettled refugees. Methods: This cross-sectional study involved 90 individuals from Syria aged 13–56 years. We used questionnaire survey to assess the general health and wellbeing in the study population in relation to a Danish reference population. Objective measurements of selected health indicators like overweight, hypertension and levels of cholesterol and blood glucose (HbA1c) were also determined for the study population. Results: Mean wellbeing scores and the proportion of study participants rating their health as good were lower among the study participants compared with the Danish population for all age groups. The proportion of participants who reported often being alone against their will was significantly higher than among Danes, as was the proportion who had nobody to talk to when having problems. A significantly higher proportion of participants experienced various forms of pain or discomfort than in the Danish population. Overall, 23.6% and 3.4% of participants had elevated cholesterol and HbA1c levels, respectively, and the prevalence of overweight (BMI ≥ 25) was 70%. Hypertension was more frequent (16.2%) than in another refugee population in Denmark (9%). Conclusions: The study demonstrated various mental and physical health challenges among the Syrian refugee families, and their health and wellbeing appeared to be substantially poorer as compared to the Danish reference population. The findings emphasize the need for systematic and specialized health care services at a municipality level to resettling refugees as a prerequisite for the refugees to become contributing citizens

Children in Greenland: disease patterns and contacts to the health care system

Background: Previous studies of Greenlandic children’s disease pattern and contacts to the health care system are sparse and have focused on the primary health care sector. Objective: We aimed to identify the disease pattern and use of health care facilities of children aged 0–10 in two Greenlandic cohorts. Methods and design: In a retrospective, descriptive follow-up of the Ivaaq (The Greenland Child Cohort) and the CLEAR (climate changes, environmental contaminants and reproductive health) birth cohorts (total n=1,000), we reviewed medical records of children aged 6–10 in 2012 with residence in Nuuk or Ilulissat (n=332). Data on diseases and health care system contacts were extracted. Diagnoses were validated retrospectively. Primary health care contacts were reviewed for a random sample of 1:6. Results: In 311 children with valid social security number, the total number of health care system contacts was 12,471 equalling 4.6 contacts per child per year. The annual incidence rate of hospital admissions was 1:10 children (total n=266, 1,220 days, 4.6 days/admission), outpatient contacts 2:10 children and primary care 3.6 per child. Contacts were overall more frequent in boys compared with girls, 39.5 versus 34.6 during the study period, p=0.02. The highest annual contact rates for diseases were: hospitalisations/acute respiratory diseases 13.9:1,000; outpatient contacts/otitis media 5.1:1,000; primary care/conjunctivitis or nasopharyngitis 410:1,000 children. Outpatient screening for respiratory tuberculosis accounted 6.2:1,000, primary care non-disease (Z-diagnosis) 2,081:1,000 annually. Complete adherence to the child vaccination programme was seen in 40%, while 5% did not receive any vaccinations. Conclusions: In this first study of its kind, the health care contact pattern in Greenlandic children showed a relatively high hospitalisation rate and duration per admission, and a low primary health care contact rate. The overall contact rate and disease pattern resembled those in Denmark, except for tuberculosis screening. Adherence to the vaccination programme was low. These findings may be helpful for the organisation and dimensioning of the Greenlandic health care system for children
