  Background Few previous studies have assessed overall morbidity at the individual level with respect to future risk of hip fracture. The aim of this register-based cohort study was to examine the association between morbidity measured by the medication-based Rx-Risk Comorbidity Index (Rx-Risk) and the risk of first hip fracture. Methods Individual-level data on medications dispensed from pharmacies (2005–2016) was retrieved from the Norwegian Prescription Database and used to calculate Rx-Risk for each calendar year. Information on first hip fractures (2006–2017) was obtained from a nationwide hip fracture database. Individuals ≥ 51 years who filled at least one prescription during the study period comprised the population at risk. Using Rx-Risk as a time-varying exposure variable, relative risk estimates were obtained by a negative binomial model. Results During 2006–2017, 94,104 individuals sustained a first hip fracture. A higher Rx-Risk was associated with increased risk of hip fracture within all categories of age and sex. Women with the highest Rx-Risk (> 25) had a relative risk of 6.1 (95% confidence interval (CI): 5.4, 6.8) compared to women with Rx-Risk ≤ 0, whereas the corresponding relative risk in women with Rx-Risk 1–5 was 1.4 (95% CI: 1.3, 1.4). Similar results were found in men. Women > 80 years with Rx-Risk 21–25 had the highest incidence rate (514 (95% CI: 462, 566) per 10, 000 person years). The relative increase in hip fracture risk with higher Rx-Risk was most pronounced in the youngest patients aged 51–65 years. Conclusions Rx-Risk is a strong predictor of hip fracture in the general outpatient population and may be useful to identify individuals at risk in a clinical setting and in future studies.

  The knowledge about why hip fracture rates in Norway have declined is sparse. Concurrent with decreasing hip fracture rates, the rates of total hip replacements (THRs) have increased. We wanted to investigate if hip fracture rates continued to decline, and whether the increase in THRs had any influence on this decline, assuming that living with a hip prosthesis precludes fracture of the operated hip. Information on hip fractures in Norway 1999-2019 was available from the Norwegian Epidemiologic Osteoporosis Studies (NOREPOS) hip fracture database and population size were available in official population tables from Statistics Norway. Primary THRs (for any cause except hip fracture) 1989-2019 were obtained from the Norwegian Arthroplasty Register. We calculated the annual age-standardized incidence rates of hip fracture by sex for the period 1999–2019. The hip fracture rates in a scenario with no hip prostheses were calculated by subtracting 0.5 persons from the population at risk for each prevalent hip prosthesis, considering that each person has two hips at risk of fracture. We estimated how much of the decline could be attributed to the increased prevalence of hip prostheses. From 1999 to 2019, age-standardized incidence rates of hip fracture decreased by 27% in women and 20% in men. The rates remained stable in those under 70 years and decreased in those 70 years and above. Excluding replaced hips from the population at risk led to higher incidence rates, and this impact was considerably larger at higher ages. The increased prevalence of hip prostheses over the period accounted for approximately 18% (20% in women and 11% in men) of the observed decline in hip fracture rates. In conclusion, the incidence of hip fractures continued to decline, and the increasing number of people living with hip prostheses contributed significantly to the observed declining time trends.

  Norway is an elongated country with large variations in climate and duration of winter season. It is also a high-risk country for osteoporotic fractures, in particular hip fractures, which cause high mortality. Although most hip fractures occur indoors, there is a higher incidence of both forearm and hip fractures during wintertime, compared with summertime. In a nationwide longitudinal cohort study, we investigated whether cold ambient (outdoor) temperatures could be an underlying cause of this high incidence and mortality. Hospitalized/outpatient forearm fractures (ICD-10 code S52) and hospitalized hip fractures (ICD-10 codes S72.0-S72.2) from 2008-2018 were retrieved from the Norwegian Patient Registry. Average monthly ambient temperatures (degrees Celsius, °C) from the years 2008-2018 were provided by the Norwegian Meteorological Institute and linked to the residential area of each inhabitant. Poisson models were fitted to estimate the association (Incidence Rate Ratios (IRR), 95% Confidence Intervals (CI)) between temperature and monthly incidence of total number of forearm and hip fractures. Flexible parametric survival models (Hazard ratios (HR), 95% CI) were used to estimate the association between temperature and post hip fracture mortality, taking the population mortality into account. Monthly temperature ranged from -20.2°C to 22.0°C, with a median of -2.0°C in winter and 14.4°C in summer. At low temperatures (

  Hip fracture is associated with excess mortality, persisting for many years after the fracture. Several factors may affect survival; however, the role of social support has been less studied. Living situation could be an indicator of a person's social support, which predicts mortality in the general population. In this longitudinal cohort study, we considered whether living alone was a risk factor for post-hip fracture mortality compared with living with a partner. Information on hip fractures from all hospitals in Norway from 2002 to 2013 was combined with the 2001 National Population and Housing Census. The association between living situation and mortality during 12.8 years of follow-up in 12,770 men and 22,067 women aged 50 to 79 years at fracture was investigated using flexible parametric survival analysis. We also estimated relative survival of hip fracture patients compared with that of the non-fractured background population in the same living situation (alone or with a partner). Higher mortality after hip fracture was found in both men and women living alone versus with a partner (hazard ratio [HR] men = 1.37, 95% confidence interval [CI] 1.29—1.44; HR women = 1.23, 95% CI 1.18—1.28, adjusting for age, education level, urbanization degree, and number of children). We demonstrated the strongest association in male hip fracture patients aged <60 years (long-term mortality HR = 3.29, 95% CI 2.25—6.49). Compared with the general population, relative survival 8 years after a hip fracture was 43% in men and 61% in women living alone, whereas relative survival in those living with a partner was 51% in men and 67% in women. In conclusion, hip fracture patients who lived alone had higher mortality than those living with a partner and lower survival relative to the general population.

  Introduction: Norway has among the highest rates of osteoporotic fractures in the world, and the incidence is higher in urban compared to rural areas. Although emission intensity in Norway has declined over time, it still exceeds limits in several cities. We previously reported a higher risk of forearm fracture with high air pollution exposure in men from Oslo. No study has investigated the association between air pollution and osteoporotic fractures at a national level. Aims: To determine the association between two important indicators of air pollution (NO2 and PM2.5) and the incidence of forearm- and hip-fracture in Norway. Methods: Register data on forearm-and hip-fracture from the entire Norwegian population >40 years were combined with data on the background population (Statistics Norway) 2008-2018. Monthly levels of air pollution indicators were modelled (with 1x1 km2 resolution) by the NordicWelfAir project, in collaboration with the Norwegian Institute for Air Research (NILU). The data were combined in Geographic Information systems. Age-adjusted Incidence Rate Ratios (IRRs) with 95% Confidence Intervals (95% CIs) were estimated in men and women separately using Poisson regression. Results: Median levels of air pollution were lower in 2016-2018 compared to 2008-2010 (NO2: 4.1 vs. 5.0 µg/m3, PM2.5: 3.5 vs. 4.4 µg/m3). They were higher in the urban areas and in the South of Norway. Categorizing into tertiles, the age-adjusted incidence of forearm fracture in women was 13% higher in areas with the highest NO2 levels (12.5-71.8 vs. 0.22-6.08 µg/m3: IRR=1.13, 95% CI: 1,11, 1.14), and 30% higher at the highest PM2.5 levels (6.7-66.2 vs. 0.9-4.1 µg/m3: IRR=1.30 ,95% CI:1.28, 1.32). The corresponding associations in men were: NO2- IRR=1.18, 95% CI:1.14, 1.22 and PM2.5- IRR=1.18, 95% CI:1.15, 1.21. There was also a higher risk of hip fracture at high levels of PM2.5 in both women (IRR=1.12, 95% CI: 1.10. 1.14) and men (IRR=1.13, 95% CI: 1.10. 1.15). At high NO2, the risk-increase in hip fracture was only seen in women: IRR=1.05, 95% CI: 1.03, 1.06. Conclusions: Preliminary analyses found age and gender-adjusted associations between air pollution and osteoporotic fractures in nationwide data. We will present results also according to other variables.

  In 2011, Norway granted pregnant undocumented women the right to antenatal care and to give birth at a hospital, but did not include them in the general practitioner and reimbursement schemes. In addition, Non-Governmental Organizations (NGO) have been running health clinics for undocumented migrants. There is a need to investigate how pregnant undocumented women use NGO clinics and how this affects their maternal health. We therefore investigated the care received, occurrence of pregnancy-related complications and maternal and perinatal outcomes in women receiving care at these clinics. In this historic cohort study we included pregnant women aged 18-49 who attended urban NGO clinics between 2009-2020 and retrieved their medical records from the hospitals in the uptake area. We compared women based on region of origin using log-binominal regression to estimate relative risk of adverse outcomes. We identified 582 pregnancies in 500 women during the study period. About half (46.5%) the women sought antenatal care after the first trimester. The women had median 1 (IQR 1-3) antenatal visit at the NGO clinics which referred 77.7% of the women to public health care. In 205 retrieved deliveries, there was a 45.9% risk for any adverse outcome. The overall risk of stillbirth was 1.0%, pre-term birth 10.3%, and emergency caesarean section 19.3%. Pregnant undocumented women who use NGO clinics receive substandard antenatal care and have a high risk of adverse maternal and perinatal outcomes. This study suggests that increased attention should be given to ensure the accessibility of adequate antenatal care to undocumented women.

  Osteoporose innebærer at benvevet blir mer porøst og kan brekke ved lav belastning. Svekkelsen i benstrukturen gir ingen symptomer før man får et brudd. Det er usikkert hvor mange som har osteoporose i Norge, men antallet er beregnet å være nærmere 300 000 personer. Ofte benyttes osteoporotiske brudd i hofte, underarm og ryggrad som mål på forekomst av osteoporose som klinisk problem. Hoftebrudd har ofte størst konsekvenser for enkeltindivid og samfunn. Det skjer et hoftebrudd hver time på døgnet i Norge, totalt ca. 9 000 per år. Kvinner og eldre er mest utsatt. Norge ligger på verdenstoppen i hoftebrudd, og vi har begrenset kunnskap om årsakene til dette. Et hoftebrudd koster nesten 1 million kroner det første året. Selv om hyppigheten har gått ned siden begynnelsen av 1990-årene, vil antall hoftebrudd likevel øke fremover pga. økende antall eldre. Osteoporose og fall er de viktigste risikofaktorene, og røyking, lav vekt, lite fysisk aktivitet og tidligere brudd, virker inn på disse. Vi omtaler her et pågående prosjekt i Oslo som følger opp fallskader for å hindre nye fall, og et omfattende prosjekt ved syv sykehus som skal forebygge nye brudd hos bruddpasienter. Vi spør også hvorfor det tilsynelatende satses så lite på å forebygge denne folkesykdommen.
