Population Based Study

Abstract Context: The association between thyroid function and blood pressure is insufficiently studied. Objective: The objective of the investigation was to study the association between TSH within the reference range and blood pressure. Design and Setting: This was a cross-sectional, population-based study. Subjects: A total of 30,728 individuals without previously known thyroid disease were studied. Main Outcome Measures: The main outcome measures were mean systolic and diastolic blood pressure and pulse pressure and odds ratio for hypertension (>140/90 mm Hg or current or previous use of antihypertensive medication), according to categories of TSH. Results: Within the reference range of TSH (0.50–3.5 mU/liter), there was a linear increase in blood pressure with increasing TSH. The average increase in systolic blood pressure was 2.0 mm Hg [95% confidence interval (CI) 1.4–2.6 mm Hg] per milliunit per liter increase in TSH among men, and 1.8 mm Hg (95% CI 1.4–2.3 mm Hg) in women. The corresponding increase in diastolic blood pressure was 1.6 mm Hg (95% CI 1.2–2.0 mm Hg) in men and 1.1 mm Hg (95% CI 0.8–1.3 mm Hg) in women. Comparing TSH of 3.0–3.5 mU/liter (upper part of the reference) with TSH of 0.50–0.99 mU/liter (lower part of the reference), the odds ratio for hypertension was 1.98 (95% CI 1.56–2.53) in men and 1.23 (95% CI 1.04–1.46) in women. Conclusion: Within the reference range of TSH, we found a linear positive association between TSH and systolic and diastolic blood pressure that may have long-term implications for cardiovascular health.

Abstract Objective: In spite of growing evidence on the associations between nutrient patterns and obesity. A few study examined the association between patterns of nutrient intake and obesity we aimed to explore the association between nutrient pattern and obesity in Iranian adults.Results: In this cross-sectional study, a total of 850 subjects aged years 20 to 59 were randomly selected. Our statistical analysis revealed three major nutrient patterns that show the principle factor loading of nutrient intake. We observed a significant association between quintiles in men for Fasting Blood Sugar (FBS) (P<0.006) in the first nutrient pattern. Moreover, we identified a significant difference between quintiles in the first nutrient pattern in women for obesity (P=0.007), Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) (P<0.02). In the third nutrient pattern, we identified a significant association for SBP in women (P<0.02).

<p>Objetivo: estimar la prevalencia y los factores asociados con una actividad física insuficiente (AFI) en el tiempo libre entre los adolescentes de una ciudad mediana en el estado de Minas Gerais, Brasil. Métodos: Los datos de la encuesta transversal ACtVU (Uberaba - MG, Brasil) realizada entre mayo y octubre de 2015. Los estudiantes de secundaria de ambos sexos (de 14 a 18 años) comprendieron la muestra. AFI (&lt;300 minutos/semana) fue la variable dependiente y los indicadores sociodemográficos, de comportamiento y de salud fueron las variables independientes evaluadas mediante cuestionarios. Se utilizó la regresión logística binaria para estimar la Odds Ratio (OR). El IMC se utilizó como variable de control. Resultados: 984 estudiantes participaron en este estudio. El porcentaje de AFI fue del 44,9% (IC95%: 41,7; 48,1) y fue mayor entre las niñas (57,1% frente al 29,3% en los niños). Se encontró una mayor probabilidad de AFI en: la calificación para ambos sexos (OR = 2.23 niños, OR = 2.28 niñas), tiempo de pantalla entre semana (OR = 1.29), uso excesivo de teléfonos inteligentes durante la semana (OR = 1.54) y los fines de semana (OR = 1.22) entre niños, que estudian esta noche (OR = 1.80), que tienen un trabajo (OR = 1.24), ingresos familiares (OR = 1.41 para 3 a 5 salarios mínimos y OR = 1.65 para ≥ 6 salarios mínimos), tiempo de pantalla entre semana (OR = 1.87) e insatisfacción con el propio peso (OR = 1.32) entre las niñas. Conclusión: la prevalencia de AFI fue alta. La mayoría de los factores asociados fueron diferentes en niños y niñas.</p>

ObjectiveIn cross-sectional studies, TSH levels within the reference range have been positively associated with blood pressure and adverse serum lipid levels. In a prospective study, we aimed to determine whether differences in TSH levels within the reference range are associated with future levels of blood pressure and lipids.DesignWe conducted a prospective population-based study.MethodsIn 9709 women and 4644 men without previous thyroid disease who had a baseline TSH level of 0.45–4.5 mU/l, we studied the associations of baseline TSH levels with blood pressure and lipid levels at follow-up 11 years later.ResultsHigher TSH levels at baseline were associated with higher systolic (P=0.002 in women) and diastolic (P=0.03 in women) blood pressure, non-HDL cholesterol (P=0.01 in men) and triglyceride (P=0.008 in men) levels and lower HDL cholesterol levels (P<0.001 in women and men) at follow-up, but the associations were very modest and not consistent between the sexes. Among people who remained free of thyroid disease, changes in TSH levels during follow-up were associated with concomitant changes in systolic and diastolic blood pressure, non-HDL cholesterol and triglyceride levels (all P<0.001), with similar results being observed for women and men. Thus, blood pressure and lipid levels increased among people with an increase in TSH levels and decreased among people with a decrease in TSH levels compared with people with no change in TSH levels.ConclusionsHigh TSH levels within the reference range may be associated with modestly higher future levels of blood pressure and adverse serum lipids. TSH levels may co-vary with blood pressure and lipid levels among people with apparently normal thyroid function.

ABSTRACT OBJECTIVE To analyze the access to and use of medicines for high blood pressure among the Brazilian population according to social and demographic conditions. METHODS Analysis of data from Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide cross-sectional, population-based study, with probability sampling, carried out between September 2013 and February 2014 in urban households in the five Brazilian regions. The study evaluated the access and use of medicines to treat people with high blood pressure. The independent variables were gender, age, socioeconomic status and Brazilian region. The study also described the most commonly used drugs and the percentage of people treated with one, two, three or more drugs. Point estimations and confidence intervals were calculated considering the sample weights and sample complex plan. RESULTS Prevalence of high blood pressure was 23.7% (95%CI 22.8–24.6). Regarding people with this condition, 93.8% (95%CI 92.8–94.8) had indication for drug therapy and, of those, 94.6% (95%CI 93.5–95.5) were using the medication at the time of interview. Full access to medicines was 97.9% (95%CI 97.3–98.4); partial access, 1.9% (95%CI 1.4–2.4); and no access, 0.2% (95%CI 0.1–0.4). The medication used to treat high blood pressure, 56.0% (95%CI 52.6–59.2) were obtained from SUS (Brazilian Unified Health System), 16.0% (95%CI 14.3–17.9) from Popular Pharmacy Program, 25.7% (95%CI 23.4–28.2) were paid for by the patients themselves and 2.3% (95%CI 1.8–2.9) were obtained from other locations. The five most commonly used drugs were, in descending order, hydrochlorothiazide, losartan, captopril, enalapril and atenolol. Of the total number of patients on treatment, 36.1% (95%CI 34.1–37.1) were using two medicines and 13.5% (95%CI 12.3–14.9) used three or more. CONCLUSIONS Access to medicines for the treatment of high blood pressure may be considered high and many of them are available free of charge. The most commonly used drugs are among those recommended as first-line treatment for high blood pressure control. The percentage of people using more than one drug seems to follow the behavior observed in other countries.

Background: Hypertension (HTN) accounts for 9.4 million deaths worldwide every year. A rise in HTN is projected by the global burden of HTN 2005 study, it portrays a grim picture. Community level data for hypertension is scarce in Andhra Pradesh. A cross sectional study was conducted to know the prevalence of hypertension in Vijayawada.Methods: 1009 apparently healthy adults visiting the hospital accompanying patients in outpatient department were screened for hypertension by blood pressure recording. All measurements were obtained by automated blood pressure measuring (AOBPM) systems.Results: Of the total population screened, hypertension accounted for 42.5% (n=429). A multivariate analysis showed that hypertension is more common in age group >50 years [odds ratio (OR)=3.004, 95% confidence interval CI being=2.2707-3.9645], in diabetics (OR=2.9091, 95% CI=2.0595-4.1092), in males (odds ratio=1.3223, 95% CI=1.0214-1.7118) and in smokers (OR=1.7442, 95% CI=1.0469-2.9059). A linear positive association was found between obesity and hypertension. No significant association was found between hypertension and alcohol intake. This study also showed that awareness was present in only 44% and 37% had hypertension under control of known hypertensive subjects.Conclusions: This is the first cross sectional study done with AOBPM. Our study finds that hypertension is an important public health burden in coastal Andhra Pradesh with low awareness, treatment, and control. It implies that strategies need to be developed to improve effective primary care management of hypertension.

Hypertensive Crises

The role of magnesium in blood pressure has been studied among hypertensive patients; however, there is a dearth of studies exploring the role of magnesium in hypertensive crises. The primary objective of this study was to evaluate the relationship between serum magnesium and blood pressure in patients with hypertensive crises. This was a single-center, retrospective, chart review, cross-sectional study of patients with hypertensive crises. Patients were included if they were eighteen years of age or older, with an international classification disease ninth revision (ICD-9) code of 401.9 (hypertensive crises: emergency or urgency) and a documented magnesium level on their electronic medical record. The primary outcome of the study was the correlation between serum magnesium and blood pressure (systolic blood pressure and diastolic blood pressure) in patients with hypertensive crises. Two hundred and ninety-three patients were included in the study. The primary outcome result showed that serum magnesium was positively correlated with systolic blood pressure (r = 0.143, p = 0.014), but not diastolic blood pressure. Conclusion: This study found a significant positive association between magnesium and systolic blood pressure, but not diastolic blood pressure, among patients with hypertensive crises. This positive association of serum magnesium with systolic blood pressure was maintained after adjusting for covariates. This study’s findings suggest a potential role of magnesium in blood pressure among patients with hypertensive crises.
