Changes in conventional cardiovascular risk factors and the estimated 10-year risk of acute myocardial infarction or cerebral stroke in Sami and non-Sami populations in two population-based cross-sectional surveys: the SAMINOR Study.

ABSTRACT:

Objective

To describe changes in cardiovascular risk factors and in the estimated 10-year risk of acute myocardial infarction (AMI) or cerebral stroke (CS) between SAMINOR 1 (2003-2004) and SAMINOR 2 (2012-2014), and explore if these changes differed between Sami and non-Sami.

Design

Two cross-sectional surveys.

Setting

Inhabitants of rural Northern Norway.

Participants

Participants were aged 40-79 years and participated in SAMINOR 1 (n=6417) and/or SAMINOR 2 (n=5956).

Primary outcome measures

Generalised estimating equation regressions with an interaction term were used to estimate and compare changes in cardiovascular risk factors and 10-year risk of AMI or CS between the two surveys and by ethnicity.

Results

Mean cholesterol declined by 0.50, 0.43 and 0.60 mmol/L in women, Sami men and non-Sami men, respectively (all p<0.001). Sami men had a small decline in mean high-density lipoprotein (HDL) cholesterol and an increase in mean triglycerides (both p<0.001), whereas non-Sami showed no change in these variables. Non-Sami women had an increase in mean HDL cholesterol (p<0.001) whereas Sami women had no change. Triglycerides did not change in non-Sami and Sami women. Systolic and diastolic blood pressure declined by 3.6 and 1.0 mm Hg in women, and 3.1 and 0.7 in men, respectively (all p<0.01). Mean waist circumference increased by 6.7 and 5.9 cm in women and men, respectively (both p<0.001). The odds of being a smoker declined by 35% in women and 46% in men (both p<0.001). Estimated 10-year risk of AMI or CS decreased in all strata of sex and ethnicity (p<0.001), however, Sami women had a smaller decline than non-Sami did.

Conclusions

Independent of ethnicity, there was a decline in mean cholesterol, blood pressure, smoking, hypertension (women only) and 10-year risk of AMI or CS, but waist circumference increased. Relatively minor ethnic differences were found in changes of cardiovascular risk factors.

Project description:BackgroundMedication for mental health problems represents a significant proportion of overall medication use and the prescription of psychotropic medicine has increased in many western countries over the last decades. Childhood violence (CV) is strongly associated with mental health problems, which in turn may increase the likelihood of being prescribed psychotropic medication. However, the association between CV and prescription of benzodiazepines (BDZ) and antidepressants is rarely described, and no such study has been performed among the Indigenous Sami people.MethodsData from the SAMINOR 2 Questionnaire Survey (2012) was linked to the Norwegian Prescription Database. Information on filled prescriptions for BDZ and antidepressants in 2004-2019 was collected for 11,296 persons (55.8% women, 22.6% Sami). Gender-stratified chi-square tests and two-sample t-tests were used to test for differences between groups. Logistic regression was applied to investigate the association between CV and filled prescriptions for BDZ and antidepressants.ResultsDuring the 16-year study period, 16.7% of all women filled at least one prescription for BDZ. The figures were significantly lower among Sami women (14.1%) compared to non-Sami women (17.4%) (p = .003). Among all women, 23.6% filled at least one prescription for antidepressants, with no difference between ethnic groups. Filled prescriptions among men were 10.0% and 14.2%, respectively, with no difference between ethnic groups. During each year, and in total, a significantly higher proportion of women exposed to CV received at least one prescription for BDZ and antidepressants, respectively, compared to women not exposed to CV, with no differences between ethnic groups. Among men, the pattern was similar.ConclusionA lower proportion of Sami women filled prescriptions for BDZ than non-Sami women. Those who reported exposure to CV filled prescriptions for BDZ and antidepressants more often than those who did not report CV. There were no overall differences between Sami and non-Sami; the dispensing rates of antidepressants and BDZ were similar for Sami and non-Sami, and the effects of CV on the dispensing of antidepressants and BDZ were also similar. This study highlights the importance of preventing CV, and of identifying a history of CV when treating adults with mental health problems.

Project description:OBJECTIVES:Underestimation of overweight/obesity may prevent weight loss attempts, resulting in further weight gain and maintenance of overweight. Mental health benefits may nevertheless surpass negative consequences. Our main objective was to study the association between underestimation of overweight/obesity and symptoms of anxiety and depression in Sami and non-Sami populations. DESIGN:Population-based cross-sectional study. SETTING:The SAMINOR 2 Clinical Study with participants from 10 municipalities in Northern Norway enrolled between 2012 and 2014. PARTICIPANTS:The study included 3266 adults of multiethnic rural origin with overweight/obesity (body mass index (BMI) ≥25 kg/m2) whereof 1384 underestimated their weight (42%). PRIMARY AND SECONDARY OUTCOME MEASURES:Primary outcome measure was symptoms of anxiety and depression and secondary outcome measures were BMI and the demographic variables: sex, age, education and marital status. RESULTS:A higher proportion of Sami men compared with non-Sami men were obese, and reported more symptoms of anxiety and depression. More men than women, and a higher proportion of Sami women compared with non-Sami women, underestimated their weight. Multivariable-adjusted analyses showed that women were less likely to underestimate their weight compared with men (OR 0.43, 95% CI 0.33 to 0.55 in Sami and OR 0.33, 95% CI 0.26 to 0.42 in non-Sami), higher BMI was protective against weight underestimation (OR 0.72, 95% CI 0.69 to 0.75 in Sami and OR 0.63, 95% CI 0.60 to 0.67 in non-Sami), slightly higher odds of weight underestimation were observed with increasing age in both ethnic groups (OR 1.03, 95% CI 1.01 to 1.05 in Sami and OR 1.02, 95% CI 1.00 to 1.03 in non-Sami), while higher education lowered the odds in non-Sami (OR 0.69, 95% CI 0.55 to 0.87). Weight underestimation was protectively associated with anxiety and depression in Sami men (OR 0.48, 95% CI 0.27 to 0.84) and in non-Sami women (OR 0.44, 95% CI 0.25 to 0.78) adjusted for age, BMI, education and marital status. CONCLUSIONS:Independent of ethnicity, more men than women underestimated their weight. Underestimation of weight was protectively associated with anxiety and depression in Sami men and non-Sami women.

Project description:ObjectiveTo examine the change in both the prevalence and severity of metabolic syndrome (MetS) in the Sami and non-Sami in Northern Norway due to a lack of knowledge regarding the development of MetS in this population.DesignRepeated cross-sectional study.SettingThe study is based on data from the SAMINOR 1 Survey (2003-2004, n=6550) and the SAMINOR 2 Clinical Survey (2012-2014, n=6004), conducted in 10 municipalities in Northern Norway.ParticipantsMen and women aged 40-79 years were invited. We excluded participants not handing in the questionnaire and with missing information concerning ethnicity questions or MetS risk factors resulting in a final sample of 6308 (36.0% Sami) subjects in SAMINOR 1 and 5866 (40.9% Sami) subjects in SAMINOR 2.Outcome measuresMetS prevalence was determined using the harmonised Adult Treatment Panel III (ATP-III) criteria, and severity was assessed with the MetS severity Z-score. Generalised estimating equations with an interaction term (survey × ethnicity) were used to compare prevalence and severity between the two surveys while accounting for partly repeated measurements.ResultsThe overall, age-standardised ATP-III-MetS prevalence was 31.2% (95% CI: 29.8 to 32.6) in SAMINOR 1 and 35.6% (95% CI: 34.0 to 37.3) in SAMINOR 2. Both the ATP-III-MetS prevalence and the mean MetS severity Z-score increased between the surveys in all subgroups, except the ATP-III-MetS prevalence in non-Sami women, which remained stable. Over time, Sami men showed a slightly larger increase in MetS severity than non-Sami men (p<0.001): the score increased by 0.20 (95% CI: 0.14 to 0.25) and 0.06 (95% CI: 0.01 to 0.10) in Sami and non-Sami men, respectively. Abdominal obesity increased markedly between the surveys in all subgroups.ConclusionThe prevalence and severity of MetS increased over time in rural Northern Norway. Abdominal obesity appeared to drive the increase in ATP-III-MetS prevalence. Sami men had a slightly larger increase in severity than non-Sami.
