  Title Incidence of total hip or knee replacement due to osteoarthritis in relation to thyroid function: a prospective cohort study (The Nord-Trondelag Health Study) Type Journal Article
  Year 2017 Publication BMC Musculoskeletal Disorders Abbreviated Journal BMC Musculoskelet Disord  
  Volume 18 Issue 1 Pages 201  
  Keywords Hip joint replacement; Knee joint replacement; Osteoarthritis; Thyroid function; Thyroid stimulating hormone  
  Abstract BACKGROUND: To study whether thyroid function was associated with risk of hip or knee replacement due to primary osteoarthritis. METHODS: In a prospective cohort study, data from the second and third survey of the Nord-Trondelag Health Study were linked to the Norwegian Arthroplasty Register in order to identify total hip or knee replacement as a result of primary osteoarthritis. RESULTS: Among 37 891 participants without previously known thyroid disease we recorded 978 total hip replacements (THRs) and 538 total knee replacements (TKRs) during a median follow-up time of 15.7 years. The analyses were adjusted for sex, age, BMI (body mass index), smoking, physical activity and diabetes. We did not find any association between TSH (thyroid stimulating hormone) and THR or TKR due to osteoarthritis. Neither were changes in TSH over time, or overt hypo- or hyperthyroidism, associated with incidence of THR or TKR. CONCLUSION: No association was found between thyroid function and hip or knee joint replacement due to osteoarthritis.

  Title Age of menarche is associated with knee joint replacement due to primary osteoarthritis (The HUNT Study and the Norwegian Arthroplasty Register) Type Journal Article
  Year 2017 Publication Osteoarthritis and Cartilage Abbreviated Journal Osteoarthritis Cartilage  
  Volume 25 Issue 10 Pages 1654-1662  
  Keywords Hip joint replacement; Hormonal therapies; Knee joint replacement; Osteoarthritis; Reproductive history  
  Abstract OBJECTIVE: To investigate whether parity, age at menarche, menopausal status, age at menopause, use of oral contraceptives (OC) or use of hormone replacement therapy (HRT) were associated with total knee replacement (TKR) or total hip replacement (THR) due to primary osteoarthritis. METHOD: In a prospective cohort study of 30,289 women from the second and third surveys of the Nord-Trondelag Health Study, data were linked to the Norwegian Arthroplasty Register (NAR) in order to identify TKR or THR due to primary osteoarthritis. Cox proportional hazards models were used to estimate the hazard ratios (HRs). RESULTS: We observed 430 TKRs and 675 THRs during a mean follow-up time of 8.3 years. Increasing age at menarche was inversely associated with the risk of TKR (P-trend < 0.001). Past users and users of systemic HRT were at higher risk of TKR compared to never users (HR 1.42 (95% confidence interval (CI) 1.06-1.90) and HR 1.40 (95% CI 1.03-1.90), respectively). No association was found between parity, age at menarche, menopausal status, age at menopause, oral contraceptive use or HRT use and THR. CONCLUSION: We found that increasing age at menarche reduced the risk of TKR. Past users and users of systemic HRT were at higher risk of TKR compared to never users. Parity did not increase the risk of THR or TKR.

  Title The Prevalence and Symptom Profile of Asthma-COPD Overlap: The HUNT Study Type Journal Article
  Year 2017 Publication Copd Abbreviated Journal Copd  
  Volume Issue Pages 1-9  
  Keywords Acos; epidemiology; obstructive lung disease; spirometry  
  Abstract The concept of asthma and COPD as separate conditions has been questioned, and the term asthma-COPD overlap syndrome has been introduced. We assessed the prevalence, symptoms, and lifestyle factors of asthma-COPD overlap (ACO) in a large Norwegian population-based study. From 2006 to 2008, a total of 50,777 residents of Nord-Trondelag participated in the Nord-Trondelag Health Study, Norway. They completed questionnaires regarding respiratory symptoms, disease status, and medication use. We estimated the prevalence and 95% confidence intervals of ACO. Additionally, spirometry was used to estimate the prevalence of ACO in a subgroup. The prevalence of self-reported ACO was 1.9%, and in age groups <40, 40-60 and >/=60 years it was 0.7%, 1.4%, and 3.2%, respectively. Among those reporting COPD, the proportion of ACO was 0.56. In the spirometry subgroup when ACO was defined as doctor diagnosed asthma ever and FEV1/FVC < 0.70, the prevalence of ACO was 2.0%. All respiratory symptoms, separately or in combination, as well as medication use were reported most frequently in those with ACO compared to the other groups. Strikingly, we observed a two-fold higher proportion of allergic rhinitis in ACO compared to COPD only. In this Norwegian population, the prevalence of self-reported ACO was 1.9%, and the corresponding proportion of ACO among those with COPD was 0.56. Participants with ACO generally had the highest proportions of respiratory symptoms compared to asthma or COPD.

  Title Is there an association between vitamin D status and risk of chronic low back pain? A nested case-control analysis in the Nord-Trondelag Health Study Type Journal Article
  Year 2017 Publication BMJ Open Abbreviated Journal BMJ Open  
  Volume 7 Issue 11 Pages e018521  
  Keywords back pain; epidemiology; vitamin D and low back  
  Abstract OBJECTIVES: To explore potential associations between vitamin D status and risk of chronic low back pain (LBP) in a Norwegian cohort, and to investigate whether relationships depend on the season of blood sample collection. DESIGN: A nested case-control study in a prospective data set. SETTING: The Norwegian community-based Nord-Trondelag Health Study (HUNT). Data were collected in the HUNT2 (1995-1997) and HUNT3 (2006-2008) surveys. MAIN OUTCOME MEASURE: Chronic LBP, defined as LBP persisting at least 3 months continuously during the past year. PARTICIPANTS: Among individuals aged 19-55 years without LBP in HUNT2, a data set was generated including 1685 cases with LBP in HUNT3 and 3137 controls without LBP. METHODS: Blood samples from the participants collected in HUNT2 were analysed for serum 25-hydroxyvitamin D (25(OH)D) level. Associations with LBP in HUNT3 were evaluated by unconditional logistic regression analysis with adjustment for age, sex, work status, physical activity at work and in leisure time, education, smoking, and body mass index. RESULTS: No association between vitamin D status and risk of chronic LBP was found in the total data set (OR per 10 nmol/L 25(OH)D=1.01, 95% CI 0.97 to 1.06) or in individuals with blood samples collected in summer/autumn (OR per 10 nmol/L 25(OH)D=0.99, 95% CI 0.93 to 1.06). For blood samples drawn in winter/spring, associations differed significantly between women and men (p=0.004). Among women a positive association was seen (OR per 10 nmol/L 25(OH)D=1.11, 95% CI 1.02 to 1.20), but among men no significant association was observed (OR per 10 nmol/L 25(OH)D=0.90, 95% CI 0.81 to 1.01). CONCLUSIONS: Overall, no association between vitamin D status and risk of LBP was demonstrated. The association suggested in women for the winter/spring season cannot be regarded as established.

  Title Adiposity, physical activity and risk of diabetes mellitus: prospective data from the population-based HUNT study, Norway Type Journal Article
  Year 2017 Publication BMJ Open Abbreviated Journal BMJ Open  
  Volume 7 Issue 1 Pages e013142  
  Keywords *Adiposity; Adult; Aged; Aged, 80 and over; Body Mass Index; Comorbidity; Diabetes Mellitus/*epidemiology; *Exercise; Female; Humans; Longitudinal Studies; Male; Middle Aged; Norway/epidemiology; Odds Ratio; Overweight/*epidemiology; Prospective Studies; Risk Factors; Young Adult; *Epidemiology; *Public Health  
  Abstract BACKGROUND: Physical activity may counteract the adverse effects of adiposity on cardiovascular mortality; however, the evidence of a similar effect on diabetes is sparse. This study examines whether physical activity may compensate for the adverse effect of adiposity on diabetes risk. METHODS: The study population consisted of 38 231 individuals aged 20 years or more who participated in two consecutive waves of the prospective longitudinal Nord-Trondelag Health Study in Norway: in 1984-1986 and in 1995-1997. A Poisson regression model with SEs derived from robust variance was used to estimate adjusted risk ratios of diabetes between categories of body mass index and physical activity. RESULTS: Risk of diabetes increased both with increasing body mass (Ptrend <0.001) and with decreasing physical activity level (Ptrend <0.001 in men and 0.01 in women). Combined analyses showed that men who were both obese and had low activity levels had a risk ratio of 17 (95% CI 9.52 to 30) compared to men who were normal weight and highly active, whereas obese men who reported high activity had a risk ratio of 13 (95% CI 6.92 to 26). Corresponding analysis in obese women produced risk ratios of 15 (95% CI 9.18 to 25) and 13 (95% CI 7.42 to 21) among women reporting low and high activity levels, respectively. CONCLUSIONS: This study shows that overweight and obesity are associated with a substantially increased risk of diabetes, particularly among those who also reported being physically inactive. High levels of physical activity were associated with a lower risk of diabetes within all categories of body mass index, but there was no clear evidence that being physically active could entirely compensate for the adverse effect of adiposity on diabetes risk.

  Title Validation of FRAX and the impact of self-reported falls among elderly in a general population: the HUNT study, Norway Type Journal Article
  Year 2017 Publication Osteoporosis International : a Journal Established as Result of Cooperation Between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA Abbreviated Journal Osteoporos Int  
  Volume 28 Issue 10 Pages 2935-2944  
  Keywords Fracture risk assessment; General population studies; Hunt; Osteoporosis  
  Abstract Fracture Risk Assessment Tool (FRAX) without bone mineral density (BMD) for hip fracture prediction was validated in a Norwegian population 50-90 years. Fracture risk increased with higher FRAX score, and the observed number of hip fractures agreed well with the predicted number, except for the youngest and oldest men. Self-reported fall was an independent risk factor for fracture in women. INTRODUCTION: The primary aim was to validate FRAX without BMD for hip fracture prediction in a Norwegian population of men and women 50-90 years. Secondary, to study whether information of falls could improve prediction of fractures in the subgroup aged 70-90 years. METHODS: Data were obtained from the third survey of the Nord-Trondelag Health Study (HUNT3), the fracture registry in Nord-Trondelag, and the Norwegian Prescription Database (NorPD), including 15,432 women and 13,585 men. FRAX hip without BMD was calculated, and hip fractures were registered for a median follow-up of 5.2 years. The number of estimated and observed fractures was assessed, ROC curves with area under the curve (AUC), and Cox regression analyses. For the group aged 70-90 years, self-reported falls the last year before HUNT3 were included in the Cox regression model. RESULTS: The risk of fracture increased with higher FRAX score. When FRAX groups were categorized in a 10-year percentage risk for hip fracture as follows, <4, 4-7.9, 8-11.9, and >/=12%, the hazard ratio (HR) for hip fracture between the lowest and the highest group was 17.80 (95% CI: 12.86-24.65) among women and 23.40 (13.93-39.30) in men. Observed number of hip fractures agreed quite well with the predicted number, except for the youngest and oldest men. AUC was 0.81 (0.78-0.83) for women and 0.79 (0.76-0.83) for men. Self-reported fall was an independent risk factor for fracture in women (HR 1.64, 1.20-2.24), and among men, this was not significant (1.09, 0.65-1.83). CONCLUSIONS: FRAX without BMD predicted hip fracture reasonably well. In the age group 70-90 years, falls seemed to imply an additional risk among women.

  Title Social capital and cigarette smoking: New empirics featuring the Norwegian HUNT data Type Journal Article
  Year 2017 Publication Economics and Human Biology Abbreviated Journal Econ Hum Biol  
  Volume 26 Issue Pages 174-185  
  Keywords *Cigarette smoking; *Instrumental variables; *Longitudinal data; *Social capital  
  Abstract Using a rich Norwegian longitudinal data set, this study explores the effects of different social capital variables on the probability of cigarette smoking. There are four social capital variables available in two waves of our data set. Our results based on probit (and OLS) analyses (with municipality fixed-effects) show that the likelihood of smoking participation is negatively and significantly associated with social capital attributes, namely, community trust (-0.017), participation in organizational activities (-0.032), and cohabitation (-0.045). Significant negative associations were also observed in panel data, pooled OLS, and random effects models for community trust (-0.024; -0.010) and cohabitation (-0.040; -0.032). Fixed-effects models also showed significant negative effects for cohabitation (-0.018). Estimates of alternative instrumental variables (IV) based on recursive bivariate probit and IV-GMM models also confirmed negative and significant effects for three of its characteristics: cohabitation (-0.030; -0.046), community trust (-0.065; -0.075), and participation in organizational activities (-0.035; -0.046). The limitations of our conclusions are discussed, and the significance of our study for the field of social capital and health is described, along with suggested avenues for future research.

  Title Validation of a Knowledge Transfer Tool for the Knee Inflammation MRI Scoring System for Bone Marrow Lesions According to the OMERACT Filter: Data from the Osteoarthritis Initiative Type Journal Article
  Year 2017 Publication The Journal of Rheumatology Abbreviated Journal J Rheumatol  
  Volume 44 Issue 11 Pages 1718-1722

  Abstract OBJECTIVE: To assess feasibility and reliability of scoring bone marrow lesions (BML) on knee magnetic resonance imaging (MRI) in osteoarthritis using the Outcome Measures in Rheumatology Knee Inflammation MRI Scoring System (KIMRISS), with a Web-based interface and online training with real-time iterative calibration. METHODS: Six readers new to the KIMRISS (3 radiologists, 3 rheumatologists) scored sagittal T2-weighted fat-saturated MRI in 20 subjects randomly selected from the Osteoarthritis Initiative data, at baseline and 1-year followup. In the KIMRISS, the reader moves a transparent overlay grid within a Web-based interface to fit bones, then clicks or touches each region containing BML per slice, to score 1 if BML is present. Regional and total scores are automatically calculated. Outcomes include the interreader intraclass correlation coefficients (ICC) and the smallest detectable change (SDC). RESULTS: Scoring took 3-12 min per scan and all readers rated the process as moderately to very user friendly. Despite a low BML burden (average score 2.8% of maximum possible) and small changes, interobserver reliability was moderate to high for BML status and change in the femur and tibia (ICC 0.78-0.88). Four readers also scored the patella reliably, whereas 2 readers were outliers, likely because of image artifacts. SDC of 1.5-5.6 represented 0.7% of the maximum possible score. CONCLUSION: We confirmed feasibility of knee BML scoring by new readers using interactive training and a Web-based touch-sensitive overlay system, finding high reliability and sensitivity to change. Further work will include adjustments to training materials regarding patellar scoring, and study in therapeutic trial datasets with higher burden of BML and larger changes.

  Title The mediating effect of body mass index on the relationship between smoking and hip or knee replacement due to primary osteoarthritis. A population-based cohort study (the HUNT Study) Type Journal Article

  Abstract To investigate the total effect of smoking on total hip or knee replacement (THR/TKR) due to primary osteoarthritis (OA) and to quantify the indirect effect of smoking through body mass index (BMI). Participants from the Nord-Trondelag Health Study (the HUNT Study) were linked to the Norwegian Arthroplasty Register to detect the first THR or TKR due to primary OA. A mediation analysis was used to decompose the total effect of smoking into a direct and indirect effect. BMI was considered a mediator in the analysis. All effects were estimated as hazard ratios (HRs) with 95% confidence intervals (CIs). The indirect effect of smoking mediated through BMI was expressed as a percentage (proportion*100). In total 55 188 participants were followed up during 17.2 years (median). We identified 1322 THRs and 754 TKRs. For men, the total effect of current vs. never smoking revealed a decreased risk of THR (HR 0.59, 95% CI 0.46-0.76) and TKR (HR 0.47, 95% CI 0.32-0.66). For women, current smoking increased the risk of THR (HR 1.34, 95% CI 1.11-1.60). For men, 6% and 7% of the risk reduction for THR and TKR, respectively, was mediated by BMI. We found a negative association between smoking and THR or TKR for men. On the contrary, smoking was associated with increased risk of THR for women. Most of the effect of smoking on joint replacement risk remained unexplained by BMI.

  Title The causal role of smoking on the risk of hip or knee replacement due to primary osteoarthritis: a Mendelian randomisation analysis of the HUNT study Type Journal Article

  Volume 25 Issue 6 Pages 817-823  
  Keywords Epidemiology; Genetic variants; Osteoarthritis; Smoking  
  Abstract OBJECTIVE: Smoking has been associated with a reduced risk of hip and knee osteoarthritis (OA) and subsequent joint replacement. The aim of the present study was to assess whether the observed association is likely to be causal. METHOD: 55,745 participants of a population-based cohort were genotyped for the rs1051730 C > T single-nucleotide polymorphism (SNP), a proxy for smoking quantity among smokers. A Mendelian randomization analysis was performed using rs1051730 as an instrument to evaluate the causal role of smoking on the risk of hip or knee replacement (combined as total joint replacement (TJR)). Association between rs1051730 T alleles and TJR was estimated by hazard ratios (HRs) and 95% confidence intervals (CIs). All analyses were adjusted for age and sex. RESULTS: Smoking quantity (no. of cigarettes) was inversely associated with TJR (HR 0.97, 95% CI 0.97-0.98). In the Mendelian randomization analysis, rs1051730 T alleles were associated with reduced risk of TJR among current smokers (HR 0.84, 95% CI 0.76-0.98, per T allele), however we found no evidence of association among former (HR 0.97, 95% CI 0.88-1.07) and never smokers (HR 0.97, 95% CI 0.89-1.06). Neither adjusting for body mass index (BMI), cardiovascular disease (CVD) nor accounting for the competing risk of mortality substantially changed the results. CONCLUSION: This study suggests that smoking may be causally associated with the reduced risk of TJR. Our findings add support to the inverse association found in previous observational studies. More research is needed to further elucidate the underlying mechanisms of this causal association.

  Abstract BACKGROUND: Suggested strategies in reducing the impact of non-communicable diseases (NCD) are early diagnosing and screening. We have limited proof of benefit of population screening for NCD. Increased mortality in persons with diagnosed NCD has been shown for decades. However, mortality in undetected NCD has barely been studied. This paper explores whether all-cause mortality differed between persons with diagnosed hypothyroidism, type 2 diabetes (T2DM), and hypertension, compared with persons with undetected-, and with persons without the corresponding disease. METHODS: A prospective cohort study of the general population in Nord-Trondelag, Norway. Persons >/=20 years at baseline 1995-97 were followed until death or June 15, 2016. Cox proportional hazards models were used to compute age and multiple adjusted hazard ratios (HR) with 95% confidence intervals (CI) for the association between disease status and all-cause mortality. The number of participants in the hypothyroidism study was 31,960, in the T2DM study 37,957, and in the hypertension study 63,371. RESULTS: Mortality was increased in persons with diagnosed type 2 diabetes and hypertension, compared to persons without corresponding disease; HR 1.69 (95% CI 1.55-1.84) and HR 1.23 (95% CI 1.09-1.39), respectively. Among persons with undetected T2DM, the HR was 1.21 (95% CI 1.08-1.37), whilst among undetected hypothyroidism and hypertension, mortality was not increased compared with persons without the diseases. Further, the association with mortality was stronger in persons with long duration of T2DM (HR 1.96 (95% CI 1.57-2.44)) and hypertension (HR 1.32 (95% CI 1.17-1.49)), compared with persons with short duration (HR 1.29 (1.09-1.53) and HR 1.16 (1.03-1-30) respectively). CONCLUSIONS: Mortality was increased in persons with diagnosed T2DM and hypertension, and in undetected T2DM, compared with persons without the diseases. The strength of the association with mortality in undetected T2DM was however lower compared with persons with diagnosed T2DM, and mortality was not increased in persons with undetected hypothyroidism and hypertension, compared with persons without the diseases. Thus, future research needs to test more thoroughly if early diagnosing of these diseases, such as general population screening, is beneficial for health.

  Title Adolescent health and subsequent risk of self-harm hospitalisation: a 15-year follow-up of the Young-HUNT cohort Type Journal Article
  Year 2017 Publication Child and Adolescent Psychiatry and Mental Health Abbreviated Journal Child Adolesc Psychiatry Ment Health  
  Volume 11 Issue Pages 25  
  Keywords Adolescence; Hospitalisation; Self-harm  
  Abstract BACKGROUND: Self-harm is associated with increased suicide risk, and constitutes a major challenge in adolescent mental healthcare. In the current study, we examined the association between different aspects of adolescent health and risk of later self-harm requiring hospital admission. METHODS: We linked baseline information from 13 to 19 year old participants (n = 8965) in the Norwegian Young-HUNT 1 study to patient records of self-harm hospitalisation during 15 years of follow-up. We used Cox regression to estimate risk factor hazard ratios (HR). RESULTS: Eighty-nine persons (71% female) were admitted to hospital because of self-harm. Intoxication/self-poisoning was the most frequent method (81%). Both mental (anxiety/depression, loneliness, being bullied) and somatic (epilepsy, migraine) health issues were associated with up to fourfold increased risk of self-harm-related hospital admission. CONCLUSIONS: Several health issues during adolescence markedly increased the risk of later self-harm hospitalisation. Current findings should be incorporated in the strive to reduce self-harming and attempted suicides among young people.

  Title Genome-wide meta-analysis of 241,258 adults accounting for smoking behaviour identifies novel loci for obesity traits Type Journal Article
  Year 2017 Publication Nature Communications Abbreviated Journal Nat Commun  
  Volume 8 Issue Pages 14977  
  Keywords  
  Abstract Few genome-wide association studies (GWAS) account for environmental exposures, like smoking, potentially impacting the overall trait variance when investigating the genetic contribution to obesity-related traits. Here, we use GWAS data from 51,080 current smokers and 190,178 nonsmokers (87% European descent) to identify loci influencing BMI and central adiposity, measured as waist circumference and waist-to-hip ratio both adjusted for BMI. We identify 23 novel genetic loci, and 9 loci with convincing evidence of gene-smoking interaction (GxSMK) on obesity-related traits. We show consistent direction of effect for all identified loci and significance for 18 novel and for 5 interaction loci in an independent study sample. These loci highlight novel biological functions, including response to oxidative stress, addictive behaviour, and regulatory functions emphasizing the importance of accounting for environment in genetic analyses. Our results suggest that tobacco smoking may alter the genetic susceptibility to overall adiposity and body fat distribution.

  Title The Combined Association of Skeletal Muscle Strength and Physical Activity on Mortality in Older Women: The HUNT2 Study Type Journal Article

  Abstract OBJECTIVE: To assess the isolated and combined associations of leg and arm strength with adherence to current physical activity guidelines with all-cause and cause-specific mortality in healthy elderly women. PATIENTS AND METHODS: This was a prospective cohort study of 2529 elderly women (72.6+/-4.8 years) from the Norwegian Healthy survey of Northern Trondelag (second wave) (HUNT2) between August 15, 1995, and June 18, 1997, with a median of 15.6 years (interquartile range, 10.4-16.3 years) of follow-up. Chair-rise test and handgrip strength performances were assessed, and divided into tertiles. The hazard ratio (HR) of all-cause and cause-specific mortality by tertiles of handgrip strength and chair-rise test performance, and combined associations with physical activity were estimated by using Cox proportional hazard regression models. RESULTS: We observed independent associations of physical activity and the chair-rise test performance with all-cause and cardiovascular mortality, and between handgrip strength and all-cause mortality. Despite following physical activity guidelines, women with low muscle strength had increased risk of all-cause mortality (HR chair test, 1.37; 95% CI, 1.07-1.76; HR handgrip strength, 1.39; 95% CI, 1.05-1.85) and cardiovascular disease mortality (HR chair test, 1.57; 95% CI, 1.01-2.42). Slow chair-test performance was associated with all-cause (HR, 1.32; 95% CI, 1.16-1.51) and cardiovascular disease (HR, 1.41; 95% CI, 1.14-1.76) mortality. The association between handgrip strength and all-cause mortality was dose dependent (P value for trend <.01). CONCLUSION: Handgrip strength and chair-rise test performance predicted the risk of all-cause and CVD mortality independent of physical activity. Clinically feasible tests of skeletal muscle strength could increase the precision of prognosis, even in elderly women following current physical activity guidelines.

  Abstract OBJECTIVE: Tobacco smoking is a risk factor for gastroesophageal reflux, but whether other tobacco products increase the risk is unclear. The aim of this study was to investigate if snus increases the risk of gastroesophageal reflux symptoms (GERS). MATERIAL AND METHODS: The study was based on the third Nord-Trondelag health study (HUNT3), a population-based study of all adult residents in Nord-Trondelag County, Norway, performed in 2006-2009. The association between self-reported severe heartburn/regurgitation and snus use was assessed by logistic regression. RESULTS: Compared to never snus users, daily snus users had a reduced risk of GERS (OR 0.77, 95% confidence interval [CI] 0.64-0.93), while previous snus users and those using <2 boxes of snus/month had an increased risk (OR 1.20, 95% CI 1.00-1.46 and OR 1.41, 95% CI 1.02-1.96, respectively). There was no association between age when starting using snus and GERS. Snus users who started using snus to quit or cut down on cigarette smoking, who started using both snus and cigarettes or cigarettes alone had an increased risk of GERS. Snus users <30 years of age had an increased risk of GERS (OR 1.49, 95% CI 1.02-2.16), while those aged between 50-60 and 60-70 years had a reduced risk (OR 0.67, 95% CI 0.49-0.93 and OR 0.51, 95% CI 0.28-0.94, respectively). CONCLUSIONS: Daily snus users had a reduced risk of GERS. However, previous snus users and subgroups of snus users had an increased risk of GERS indicating reverse causality, such that snus use could increase the risk of GERS.

  Abstract We screened variants on an exome-focused genotyping array in >300,000 participants (replication in >280,000 participants) and identified 444 independent variants in 250 loci significantly associated with total cholesterol (TC), high-density-lipoprotein cholesterol (HDL-C), low-density-lipoprotein cholesterol (LDL-C), and/or triglycerides (TG). At two loci (JAK2 and A1CF), experimental analysis in mice showed lipid changes consistent with the human data. We also found that: (i) beta-thalassemia trait carriers displayed lower TC and were protected from coronary artery disease (CAD); (ii) excluding the CETP locus, there was not a predictable relationship between plasma HDL-C and risk for age-related macular degeneration; (iii) only some mechanisms of lowering LDL-C appeared to increase risk for type 2 diabetes (T2D); and (iv) TG-lowering alleles involved in hepatic production of TG-rich lipoproteins (TM6SF2 and PNPLA3) tracked with higher liver fat, higher risk for T2D, and lower risk for CAD, whereas TG-lowering alleles involved in peripheral lipolysis (LPL and ANGPTL4) had no effect on liver fat but decreased risks for both T2D and CAD.

  Title Multiple lifestyle behaviours and mortality, findings from a large population-based Norwegian cohort study – The HUNT Study Type Journal Article
  Year 2017 Publication BMC Public Health Abbreviated Journal BMC Public Health  
  Volume 17 Issue 1 Pages 58  
  Keywords Adult; Aged; Alcohol Drinking/epidemiology; Cohort Studies; Diet/adverse effects; Female; Follow-Up Studies; Humans; *Life Style; Male; Middle Aged; Norway/epidemiology; Proportional Hazards Models; Risk Factors; *Risk-Taking; Sleep; Smoking/adverse effects; Social Behavior; Young Adult; *All-cause mortality; *Cardiovascular disease; *Cohort study; *Lifestyle behaviour; *Metabolic disease; *Risk factors  
  Abstract BACKGROUND: Lifestyle risk behaviours are responsible for a large proportion of disease burden and premature mortality worldwide. Risk behaviours tend to cluster in populations. We developed a new lifestyle risk index by including emerging risk factors (sleep, sitting time, and social participation) and examine unique risk combinations and their associations with all-cause and cardio-metabolic mortality. METHODS: Data are from a large population-based cohort study in a Norway, the Nord-Trondelag Health Study (HUNT), with an average follow-up time of 14.1 years. Baseline data from 1995-97 were linked to the Norwegian Causes of Death Registry. The analytic sample comprised 36 911 adults aged 20-69 years. Cox regression models were first fitted for seven risk factors (poor diet, excessive alcohol consumption, current smoking, physical inactivity, excessive sitting, too much/too little sleep, and poor social participation) separately and then adjusted for socio-demographic covariates. Based on these results, a lifestyle risk index was developed. Finally, we explored common combinations of the risk factors in relation to all-cause and cardio-metabolic mortality outcomes. RESULTS: All single risk factors, except for diet, were significantly associated with both mortality outcomes, and were therefore selected to form a lifestyle risk index. Risk of mortality increased as the index score increased. The hazard ratio for all-cause mortality increased from 1.37 (1.15-1.62) to 6.15 (3.56-10.63) as the number of index risk factors increased from one to six respectively. Among the most common risk factor combinations the association with mortality was particularly strong when smoking and/or social participation were included. CONCLUSIONS: This study adds to previous research on multiple risk behaviours by incorporating emerging risk factors. Findings regarding social participation and prolonged sitting suggest new components of healthy lifestyles and potential new directions for population health interventions.

  Abstract BACKGROUND: There is little knowledge about the consumption of alcohol among Chinese and Norwegian older adults aged 65 years and over. The aim of this study was to investigate the prevalence and factors related to alcohol consumption among older adults in China and Norway. METHODS: The Chinese Longitudinal Healthy Longevity Survey (CLHLS) data in 2008-2009 conducted in China and The Nord-Trondelag Health Study data in 2006-2008 (HUNT3) conducted in Norway were used. Mulitvariable logistic regression was used to test the factors related to alcohol consumption. RESULTS: The prevalence of participants who drink alcohol in the Chinese and Norwegian sample were 19.88% and 46.2%, respectively. The weighted prevalence of participants with consumption of alcohol in the Chinese sample of women and men were 7.20% and 34.14%, respectively. In the Norwegian sample, the prevalence of consumption of alcohol were 43.31% and 65.35% for women and men, respectively. Factors such as younger age, higher level of education, living in urban areas, living with spouse or partner, and better health status were related to higher likelihood of alcohol consumption among Norwegian older women and men; while reported better health status and poorer life satisfaction were related to higher likelihood of alcohol consumption among Chinese. In addition, rural males and older females with higher level of education were more likely to consume alcohol. CONCLUSION: The alcohol consumption patterns were quite different between China and Norway. Besides economic development levels and cultures in the two different countries, demographic characteristics, socioeconomic status, overall health status, and life satisfaction were associated with alcohol consumption as well.

  Abstract OBJECTIVES/HYPOTHESIS: To study the prevalence and usefulness of audiometric notches in the diagnosis of noise-induced hearing loss (NIHL). STUDY DESIGN: Audiograms and data on noise exposure from 23,297 men and 26,477 women, aged 20 to 101 years, from the Nord-Trondelag Hearing Loss Study, 1996-1998. METHODS: The prevalence of four types of audiometric notches (Coles, Hoffman, Wilson) and 4 kHz notch were computed in relation to occupational noise exposure, age, sex, and report of recurrent ear infections. RESULTS: The prevalence of notches in the 3 to 6 kHz range (Wilson, Hoffman, and Coles) ranged from 50% to 60% in subjects without occupational noise exposure, and 60% to 70% in the most occupationally noise-exposed men. The differences were statistically significant only for bilateral notches. For 4 kHz notches, the prevalence varied from 25% in occupationally nonexposed to 35% in the most occupationally exposed men, and the differences were statistically significant for both bilateral and unilateral notches. For women, the prevalence of notches was lower than in men, especially for 4 kHz notches, and the differences between occupationally noise exposed and nonexposed were smaller. Recreational exposure to high music was not associated with notched audiograms. CONCLUSIONS: The detection of bilateral notches and unilateral 4 kHz notches is of some value in diagnosing NIHL, especially in men. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:1442-1450, 2017.
