Interprofessional follow-up for people at risk of type 2 diabetes in primary healthcare - a randomized controlled trial with embedded qualitative interviews.

OBJECTIVE: To examine the effects of an empowerment-based interprofessional lifestyle intervention program among people at risk of type 2 diabetes on knowledge, skills, and confidence in self-management, health, psychological well-being, and lifestyle characteristics, and to explore the participants' perceptions of participating in the intervention. DESIGN AND METHODS: In line with the Medical Research Council complex interventions research methods framework, we conducted a randomized controlled trial with embedded qualitative interviews in primary healthcare clinics in Norway between 2019-2021. Of the patients at risk (The Finnish Diabetes Risk Score Calculator (FINDRISC) ≥15 or Body Mass Index (BMI) ≥30) 142 accepted the invitation, and 14 participants from the intervention group participated in individual interviews after the 12-month follow-up. Our primary outcome was the Patient Activation Measure (PAM-13). Secondary outcomes were EQ-5D-5L, EQ-VAS, WHO-Overall health, WHO-Overall QOL, weight, height, waist circumference, and regularity of physical activity. We used thematic analysis to analyse the qualitative data. RESULTS: There was no clinically relevant differences of neither the primary nor the secondary endpoints between intervention and control group. As to the qualitative data, we identified two distinct features: 'Meaningful perspectives on lifestyle changes' and 'Lifestyle change is not a linear process due to challenges faced along the way' putting ownership of their choices in life into picture. CONCLUSION: The negative results of the RCT stand in contrast to the findings given by the participants voices, perceiving the intervention as a key eye opener placing their health challenges in perspective. How to interpret these seemingly conflicting findings of participants being seen, heard, and understood, helping them to take more conscious ownership of their choices in life, and at the same time demonstrating no improvements in symptoms or measures, is a dilemma that needs further exploration. We should be careful to implement interventions that do not demonstrate any effects on the quantitative outcomes.

Prevalence of increased risk of type 2 diabetes in general practice: a cross-sectional study in Norway.

BACKGROUND: Type 2 diabetes (T2D) is a global public health problem, but the onset can be delayed or prevented with adequate intervention in individuals with increased risk. Therefore, a major challenge in general practice is to identify individuals at risk of diabetes. However, limited knowledge is available about the prevalence of high diabetes risk individuals in a primary care population. In a cohort of consecutive patients in general practice we examined the prevalence of known diabetes and estimated risk of diabetes using The Finnish Diabetes Risk Score (FINDRISC) calculator, by sociodemographic and clinical characteristics. METHODS: This study was a cross-sectional study conducted in four general practices in Western and Eastern Norway. A total of 1682 individuals, 20-80 years of age, were assessed for eligibility from May to December 2019. We excluded patients who actively declined participation (n = 112), were lost because of various organization challenges (n = 103) and patients who did not fulfil the inclusions criteria (n = 63). Diabetes prevalence and prevalence of individuals at risk of T2D with 95% confidence intervals (CI) were estimated for the total sample, by age group and for men and women separately. We tested for differences between groups using t-test for continuous variables and chi-square test (Pearson Chi-Square) for categorical variables. RESULTS: Of 1404 individuals, 132 reported known diabetes, yielding a prevalence of 9.9% (95% CI 8.4-11.6). Among participants without a known diagnosis of diabetes, the following estimates of elevated risk assessment scores were found: FINDRISC score ≥ 11 32.8% (95% CI 30.3-35.4) and FINDRISC ≥ 15 10.0% (95% CI 8.6-11.9). Comparable results were found between the sexes. CONCLUSIONS: Detection of unknown diabetes and individuals with increased risk, is of high public health relevance for early implementation of preventive measures aimed to reduce the risk of diabetes and its complications through lifestyle modification. A simple, non-expensive questionnaire, such as FINDRISC, may be valuable as an initial screening method in general practice to identify those in need for preventive measures.

Patient activation in adults attending appointments in general practice: a cross-sectional study.

BACKGROUND: Patient activation refers to patients' knowledge, confidence, skills, ability, beliefs, and willingness to manage their health and healthcare. Patient activation is an essential component of self-management and identifying patient activation levels will identify people at risk for health decline at an earlier stage. We aimed to explore patient activation in among adults attending general practice by (1) investigating differences in patient activation according to characteristics and markers of health-related behaviour; (2) examining the associations of quality of life and satisfaction with health with patient activation; and (3) comparing patient activation between persons with or without type 2 diabetes (T2D) and with or without elevated T2D risk. METHODS: We performed a cross-sectional study and recruited 1,173 adult patients from four Norwegian general practices between May to December 2019. The participants completed a questionnaire containing sociodemographic and clinical variables, the Patient Activation Measure (PAM-13), the quality of life and satisfaction with health items from the WHO Quality of Life-BREF, three questions about exercise (regularity, intensity and exercise time), the Finnish Diabetes Risk Score (FINDRISC) and Body Mass Index. We tested differences between groups and associations using Chi-squared tests, Fisher's exact tests, t-tests, one-way ANOVAs and Spearman's rho tests. RESULTS: The sample's mean PAM-13 score was 69.8 (0-100) (SD 14.8). In the total population, we found that participants reporting higher patient activation scores also reported more favourable health-related behaviours (exercise and healthy eating). We found positive correlations between the PAM-13 scores and, respectively, the quality of life score and the satisfaction with health score. We found no differences in patient activation between people with or without T2D and those with or without elevated T2D risk. CONCLUSIONS: We found that higher patient activation was associated with favourable health-related behaviours, a better quality of life and better satisfaction with health among adults attending four general practices in Norway. Assessing patient activation has the potential to help general practitioners identify patients who might benefit from closer follow-up in advance of negative health outcomes.

Is the risk of cardiovascular disease in women with pre-eclampsia modified by very low or very high offspring birth weight? A nationwide cohort study in Norway.

OBJECTIVES: To examine whether the risk of cardiovascular disease (CVD) in women with pre-eclampsia is modified by very low or very high offspring birth weight. Further, we studied whether diabetes in pregnancy modified this risk. DESIGN: Nationwide cohort study. SETTING: Norwegian population registries. PARTICIPANTS: 618 644 women who gave birth to their first child during 1980-2009. METHODS: The women were followed from delivery until the development of CVD or censoring, by linkage of the Medical Birth Registry of Norway to the Cardiovascular Disease in Norway project, and the Norwegian Cause of Death Registry. PRIMARY OUTCOME MEASURE: CVD. RESULTS: Compared with normotensive women with normal offspring birth weight, women with pre-eclampsia had increased risk of CVD (HR 2.16; 95% CI 2.05 to 2.26). The CVD risk was even higher when pre-eclampsia was accompanied with a large for gestational age offspring (LGA, z-score >2.0) (HR 2.57; 95% CI 2.08 to 3.18). Women with pre-eclampsia and a small for gestational age offspring (SGA, z-score <-2.0) had an HR of 1.54 (95% CI 1.23 to 1.93) compared with normotensive women with normal offspring birth weight.Also, women with diabetes had increased CVD risk, but no additional risk associated with an LGA or SGA offspring. CONCLUSIONS: Women with pre-eclampsia and an LGA offspring had higher risk of CVD than pre-eclamptic women with a normal weight (z-score -2.0 to 2.0) or SGA offspring. These findings suggest that factors causing pre-eclampsia and an LGA offspring are also linked to development of CVD.

Casual blood glucose and subsequent cardiovascular disease and all-cause mortality among 159 731 participants in Cohort of Norway (CONOR).

INTRODUCTION: Our aim was to assess the association between casual blood glucose level and subsequent cardiovascular disease (CVD) and mortality among community-dwelling adults without a diagnosis of diabetes. RESEARCH DESIGN AND METHODS: In this community-based cohort study, 159 731 individuals with a measurement of casual blood glucose were followed from their participation date in Cohort of Norway (CONOR) (1994-2003) until a CVD episode, death or 31 December 2009. All analyses were done using Cox proportional hazard regression, and the results are reported as multivariable-adjusted HRs with 95% CI. RESULTS: Compared with those with normal glucose levels (<7.8 mmol/L), participants categorized as having borderline (7.8-11.0 mmol/L) levels showed an increased risk of a stroke (HR 1.29; 95% CI 1.12 to 2.49) and cardiovascular (HR 1.29; 95% CI 1.12 to 2.48), and all-cause (HR 1.27; 95% CI 1.16 to 1.38) mortality, while participants with high glucose levels (>11.0 mmol/L) had an even more increased risk. One mmol/L increase in glucose level was associated with an increased risk of all four endpoints among participants with borderline as well as within normal glucose levels. In analyses stratified by sex and age group, the CVD risk estimates tended to be higher in women than in men and in those <65 years of age but no significant interactions were found. CONCLUSION: An increase in casual blood glucose levels, even within the range of normal and borderline levels, was positively associated with increased risk of CVD and mortality among community-dwelling adults without a known diagnosis of diabetes.

Heart Failure in Women With Hypertensive Disorders of Pregnancy: Insights From the Cardiovascular Disease in Norway Project.

Hypertensive disorders of pregnancy (HDP) have been associated with heart failure (HF). It is unknown whether concurrent pregnancy complications (small-for-gestational-age or preterm delivery) or recurrent HDP modify HDP-associated HF risk. In this cohort study, we included Norwegian women with a first birth between 1980 and 2004. Follow-up occurred through 2009. Cox models examined gestational hypertension and preeclampsia in the first pregnancy as predictors of a composite of HF-related hospitalization or HF-related death, with assessment of effect modification by concurrent small-for-gestational-age or preterm delivery. Additional models were stratified by final parity (1 versus ≥2 births) and tested associations with recurrent HDP. Among 508 422 women, 565 experienced incident HF over a median 11.8 years of follow-up. After multivariable adjustment, gestational hypertension in the first birth was not significantly associated with HF (hazard ratio, 1.41 [95% CI, 0.84-2.35], P=0.19), whereas preeclampsia was associated with a hazard ratio of 2.00 (95% CI, 1.50-2.68, P<0.001). Among women with HDP, risks were not modified by concurrent small-for-gestational-age or preterm delivery (Pinteraction=0.42). Largest hazards of HF were observed in women whose only lifetime birth was complicated by preeclampsia and women with recurrent preeclampsia. HF risks were similar after excluding women with coronary artery disease. In summary, women with preeclampsia, especially those with one lifetime birth and those with recurrent preeclampsia, experienced increased HF risk compared to women without HDP. Further research is needed to clarify causal mechanisms.

Hypertensive pregnancy disorders increase the risk of maternal cardiovascular disease after adjustment for cardiovascular risk factors.

BACKGROUND AND AIM: Hypertensive pregnancy disorders are associated with subsequent cardiovascular disease (CVD), but the extent to which this association is explained by shared risk factors is unknown. We aimed to evaluate whether hypertensive pregnancy disorder in first pregnancy is associated with increased subsequent risk of maternal CVD after adjustment for established CVD risk factors measured after pregnancy. METHODS AND RESULTS: A total of 20,075 women with a first delivery registered in the Medical Birth Registry of Norway (1980-2003) participated in Cohort of Norway (CONOR) health surveys a mean (standard deviation) of 10.7 (5.5) years after delivery. They were then followed (median 11.4 years) for an incident fatal or non-fatal CVD event through linkage to the Cardiovascular Disease in Norway (CVDNOR) database and the Norwegian Cause of Death Registry. Hypertensive pregnancy disorders were associated with an increased risk of CVD [Hazard ratio (HR) 2.3; 95% confidence interval (CI) 1.9-2.8], which remained significant after adjustment for established CVD risk factors including body mass index, smoking, hypertension, diabetes, serum glucose and lipid levels (HR 1.5; 95% CI 1.2-1.8). The population attributable fraction of CVD due to hypertensive pregnancy disorder was 4.3% (95% CI 1.9-6.6) after multivariable adjustment. CONCLUSION: The association between hypertensive pregnancy disorders and CVD risk was mediated in part by related CVD risk factors measured 10 years following delivery. These results underline the importance of post-pregnancy follow-up of women with hypertensive pregnancy disorders focusing on modifiable, lifestyle related risk factors to prevent future CVD.

Association Between Gestational Hypertension and Risk of Cardiovascular Disease Among 617 589 Norwegian Women.

BACKGROUND: Preeclampsia and gestational hypertension (GH) are the most common hypertensive pregnancy disorders. Preeclampsia has been linked to increased risk of cardiovascular disease (CVD), but a similar association for GH has not been established. We aimed to determine the association between GH and subsequent CVD, and explore the additional role of small-for-gestational-age infants, preterm delivery, and parity. METHODS AND RESULTS: Data from the Medical Birth Registry of Norway were linked to the Cardiovascular Disease in Norway project and the Norwegian Cause of Death Registry. Hazard ratios and 95% confidence intervals were computed using Cox proportional hazard regression, comparing women with and without GH during their first and/or second pregnancy. We included all women with a first delivery from 1980 through 2009 (n=617 589) and followed them for a median of 14.3 (quartile 1-quartile 3: 6.9-21.5) years. Women with GH in the first pregnancy had 1.8-fold (95% confidence interval, 1.7-2.0) higher risk of subsequent CVD compared with women without any hypertensive pregnancy disorder. When GH occurred in combination with small-for-gestational-age infants and/or preterm delivery, the hazard ratio was 2.6 (95% confidence interval, 2.3-3.0). When women with GH were compared with women with preeclampsia, the risk of CVD was comparable when the pregnancy complications occurred in either the first or second pregnancy but was significantly higher for preeclampsia without complications when the disorder occurred in both pregnancies. CONCLUSIONS: GH was associated with increased risk of subsequent CVD, and the highest risk was observed when GH was combined with small-for-gestational-age infants and/or preterm delivery.

Incident Coronary Heart Disease After Preeclampsia: Role of Reduced Fetal Growth, Preterm Delivery, and Parity.

BACKGROUND: Preeclampsia is a severe pregnancy disorder often complicated by reduced fetal growth or preterm delivery and is associated with long-term maternal morbidity and mortality. We aimed to assess the association between preeclampsia phenotypes and risk of subsequent coronary heart disease and maternal cardiovascular mortality. METHODS AND RESULTS: Women aged 16 to 49 years who gave birth during 1980-2002 and registered in the Medical Birth Registry of Norway were followed prospectively (1-29 years) for an incident major coronary event and mortality through linkage with the Cardiovascular Disease in Norway 1994-2009 (CVDNOR) project and the Norwegian Cause of Death Registry. Preeclampsia was subdivided based on the presence of a child born small for gestational age or preterm delivery. Among 506 350 women with 1 to 5 singleton births, there were 1275 (0.3%) occurrences of major coronary event, 468 (0.1%) cardiovascular deaths, and 5411 (1.1%) deaths overall. Compared with women without preeclampsia, the hazard ratio (95% CI) for major coronary event was 2.1 (1.73-2.65) after preeclampsia alone, 3.3 (2.37-4.57) after preeclampsia in combination with small for gestational age, and 5.4 (3.74-7.74) after preeclampsia in combination with preterm delivery. Analyses distinguishing women with 1 (n=61 352) or >1 (n=281 069) lifetime pregnancy and analyses with cardiovascular mortality as outcome followed the same pattern. CONCLUSIONS: The occurrence of major coronary events was increased among women with preeclampsia and highest for preeclampsia combined with a child born small for gestational age and/or preterm delivery.

Poor self-rated health associated with an increased risk of subsequent development of lung cancer.

PURPOSE: Self-rated health has shown to be a strong predictor of mortality and some major chronic diseases. The purpose of this study was to investigate whether poor self-rated health also was related to an increased risk of subsequent development of cancer. METHODS: Information on self-rated health, life-style factors, and other health-related risk factors was ascertained in a cohort of 25,532 persons participating in the Hordaland Health Study in 1997-1999. Information on development of cancer during 10 years of follow-up was obtained from the Norwegian Cancer Registry. The relationship between self-rated health and development of cancer was examined using Cox regression analysis adjusting for smoking and other life-style factors. RESULTS: Respondents reporting a poor health showed a non-significant increased risk of overall cancer. Sub-analysis of the four most common types of cancer showed a statistically significant association between self-rated health and lung cancer. The adjusted hazard ratio was 3.88 (95% CI; 0.99, 15.8) for those rating their health as poor compared to very good (p for trend = 0.038). For the other types of cancer, we found a non-significant elevated risk associated with poor self-rated health. CONCLUSION: Respondents who perceive their health as poor had an increased risk of developing lung cancer also after adjusting for smoking. This suggests that self-rated health reflects a broad range of factors important for development of this cancer type. Nevertheless, due to the explorative analysis of the specific cancer types, these findings need to be repeated before elaborate interpretations can be made.
