Associations of Anxiety Symptoms With 6-Year Blood Pressure Changes and Incident Hypertension: Results From the Hispanic Community Health Study/Study of Latinos.

BACKGROUND: Despite the high burden of anxiety and hypertension in Hispanic/Latino adults, little is known about their association in this population. PURPOSE: To examine the associations of anxiety symptoms with 6-year changes in blood pressure (BP) and incident hypertension in Hispanic/Latino adults. METHODS: We examined data from a probability sample of 10,881 Hispanic/Latino persons aged 18-74 who attended visits 1 (V1; 2008-2011) and 2 (V2; 2014-2017) of the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a prospective cohort study. Anxiety symptoms were assessed at V1 using the 10-item Spielberger Trait Anxiety Scale (M = 17.1; Range = 10-40) and dichotomized using a cut-point of 20, the highest quartile in this cohort. BP was measured at both visits using a standardized protocol. RESULTS: Adults with elevated anxiety symptoms had a 1.02 mm Hg greater increase in systolic (p = .02) and a 0.75 mm Hg greater increase in diastolic BP (p = .02) over 6.1 years than those with lower symptoms, after adjusting for sociodemographic and clinical covariates. These associations differed by sex. Elevated anxiety was associated with a greater increase in systolic and diastolic BP in men only. Among persons without hypertension at V1 (N = 7,412), those with elevated anxiety symptoms at V1 had a 22% higher incidence of hypertension (p = .02) 6.1 years later. CONCLUSIONS: Our findings underscore the importance of screening for and treating elevated anxiety symptoms to help prevent hypertension. Further research on the role of sex and underlying mechanisms is warranted.

This study investigated the relationship between anxiety symptoms and changes in blood pressure, as well as the incidence of hypertension among Hispanic/Latino adults over time. Using data from 10,881 Hispanic/Latino adults who participated in the Hispanic Community Health Study/Study of Latinos, we found that men, but not women, with elevated anxiety symptoms experienced a greater increase in both systolic and diastolic blood pressure over a 6-year period compared to those with lower symptoms. Additionally, among 7,412 participants who were free of hypertension at baseline, individuals with elevated anxiety symptoms developed hypertension at a higher rate after 6 years of follow-up compared to those with lower symptoms. These findings suggest that anxiety symptoms play a role in the development of hypertension among Hispanic/Latino adults, underscoring the importance of screening for and addressing elevated anxiety to potentially prevent hypertension.

Retrospective study of serial polysomnograms of bronchopulmonary dysplasia patients with oxygen dependence.

INTRODUCTION: This retrospective study describes characteristics of serial polysomnograms (PSGs) of BPD patients on home oxygen therapy and describes PSG parameters associated with discontinuation of supplemental oxygen. METHODS: A single-center study was performed at Children's Hospital Los Angeles, where serial PSGs for 44 patients with BPD infants discharged on home oxygen therapy were extracted for maximum of five PSGs or until oxygen discontinuation. Clinical and polysomnography data was collected. Characteristics of PSG1 were compared amongst the patients who were weaned from oxygen after PSG2 and PSG3. RESULTS: Of 44 patients, 68.2% of patients were males with median birth gestational age of 26 weeks (IQR: 24.6-28.1), median birthweight of 777.5 g (IQR: 632.5-1054 g) and 77.3% of the cohort had severe BPD. A total of 138 PSGs were studied between all 44 patients serially. When comparing PSG1 and PSG2 parameters, statistically significant improvement was noted in multiple parameters. Median baseline SpO2, peak RR, and average PETCO2 were found to be potential predictors of prolonged oxygen use. Gestational age and birth weight were not associated with prolonged oxygen use after PSG3. The median age of oxygen discontinuation was calculated to be about 2 years of age. CONCLUSIONS: The severity of hypoxia and tachypnea on initial infant PSG are associated with prolonged oxygen therapy past 2 years of age. Growth and development of lungs with maturation of control of breathing help improve these parameters over time regardless of BPD severity. The study may inform discussions between providers and parents for patients discharged home on oxygen therapy.

Sleep Apnea and Hypertension Control among Hispanic/Latino Adults in the United States: Results from the Hispanic Community Health Study / Study of Latinos (HCHS/SOL).

Objectives: Hispanic/Latino adults have a high prevalence of uncontrolled hypertension predisposing them to CVD. We hypothesize that sleep apnea severity is associated with uncontrolled blood pressure (BP) and resistant hypertension in Hispanic/Latino adults. Methods: This was a cross-sectional study of 2,849 Hispanic Community Health Study/Study of Latinos participants with hypertension (i.e., systolic BP ≥130 mm Hg, or diastolic BP ≥80 mm Hg or self-reported antihypertensive medication use) who were taking at least one class of antihypertensive medication. Participants were categorized as having controlled (BP < 130/80 mmHg among those on hypertension treatment) , uncontrolled (BP ≥ 130/80 mmHg using one or two classes of antihypertensive medications), or resistant hypertension (BP ≥ 130/80 mmHg while on ≥ 3 classes of antihypertensive medications or the use of ≥ 4 classes of antihypertensive medications regardless of BP control). Sleep apnea was classified based on the respiratory event index (REI; events/h) as mild (REI ≥ 5 and < 15), moderate-to-severe (REI ≥ 15), or no sleep apnea (REI < 5). Results: In multinomial logistic regression, moderate-to-severe sleep apnea (vs. no sleep apnea) was associated with higher odds of resistant hypertension (Odds Ratio [OR], 2.15; 95% CI, 1.36-3.39 at 4% desaturation and OR 1.68; 95% CI, 1.05-2.67 at 3% desaturation). Neither mild nor moderate-to-severe sleep apnea was associated with uncontrolled hypertension. Conclusion: Among diverse Hispanic/Latino persons, moderate-to-severe but not mild sleep apnea was associated with resistant hypertension. Identification and management of sleep apnea in this population may improve BP control and subsequently prevent adverse cardiovascular outcomes.

Exploratory study evaluating the relationships between perinatal adversity, oxidative stress, and infant neurodevelopment across the first year of life.

Early childhood adversity increases risk for negative lifelong impacts on health and wellbeing. Identifying the risk factors and the associated biological adaptations early in life is critical to develop scalable early screening tools and interventions. Currently, there are limited, reliable early childhood adversity measures that can be deployed prospectively, at scale, to assess risk in pediatric settings. The goal of this two-site longitudinal study was to determine if the gold standard measure of oxidative stress, F2-Isoprostanes, is potentially a reliable measure of a physiological response to adversity of the infant and mother. The study evaluated the independent relationships between F2-Isoprostanes, perinatal adversity and infant neurocognitive development. The study included mother-infant dyads born >36 weeks' gestation. Maternal demographic information and mental health assessments were utilized to generate a perinatal cumulative risk score. Infants' development was assessed at 6 and 12 months and both mothers and infants were assayed for F2-isoprostane levels in blood and urine, respectively. Statistical analysis revealed that cumulative risk scores correlated with higher maternal (p = 0.01) and infant (p = 0.05) F2-isoprostane levels at 6 months. Infant F2-isoprostane measures at 2 months were negatively associated with Mullen Scales of Early Learning Composite scores at 12 months (p = 0.04). Lastly, higher cumulative risk scores predicted higher average maternal F2-isoprostane levels across the 1-year study time period (p = 0.04). The relationship between perinatal cumulative risk scores and higher maternal and infant F2-isoprostanes at 6 months may reflect an oxidative stress status that informs a sensitive period in which a biomarker can be utilized prospectively to reveal the physiological impact of early adversity.

Hypertension in Mexican adults: results from the National Health and Nutrition Survey 2006 / Hipertensión en adultos mexicanos: resultados de la Encuesta Nacional de Nutrición y Salud 2006

OBJECTIVE: To describe the prevalence of hypertension among Mexican adults, and to compare to that observed among Mexican-Americans living in the US. MATERIAL AND METHOD: The primary data source came from adults (>20 years) sampled (n=33366) in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006). Hypertension was defined when systolic blood pressure was >140 and/or diastolic was >90 or patients previously diagnosed. RESULTS: A total of 43.2 percent of participants were classified as having hypertension. We found a positive statistically significant association (p<0.05) between hypertension and BMI, abdominal obesity, previous diagnosis of diabetes and hypercholesterolemia. Subjects with hypertension had a significantly higher odd of having a history of diabetes or hypercholesterolemia. Hypertension had a higher prevalence in Mexico than among Mexican-Americans living in the US. CONCLUSIONS: Hypertension is one of the most prevalent chronic diseases in Mexico. In the last six years in Mexico, a substantial increase (25 percent) has been observed in contrast to the reduction seen among Mexican-Americans (-15 percent).

OBJETIVO: Describir la prevalencia de hipertensión arterial de adultos mexicanos y compararla con la observada en mexicanos residentes en Estados Unidos (EUA). MATERIAL Y MÉTODOS: La principal fuente de información fue la muestra de adultos (>20 años) que participaron en la Encuesta Nacional de Salud y Nutrición 2006 (ENSANUT 2006) (n=33366). El diagnóstico de hipertensión se definió cuando la tensión arterial sistólica y/o diastólica fue >140/> 90 mmHg, o tenían diagnóstico médico previo. RESULTADOS: El 43.2 por ciento tuvo diagnóstico de hipertensión. Se encontró una asociación positiva (p<0.05) entre hipertensión e índice de masa corporal (IMC), obesidad abdominal, diagnóstico previo de diabetes e hipercolesterolemia. Los hipertensos tuvieron una razón de momios mayor de tener antecedente de diabetes o hipercolesterolemia. La prevalencia de hipertensión fue mayor en México, que entre mexicanos residentes en EU. CONCLUSIONES: La hipertensión es una de las enfermedades crónicas más frecuentes en México. En los últimos seis años se observó un incremento en la prevalencia en mexicanos (25 por ciento) en comparación con la reducción en la de mexicanos residentes en EUA (-15 por ciento).

Obesity and central adiposity in Mexican adults: results from the Mexican National Health and Nutrition Survey 2006 / Obesidad y adiposidad central en adultos mexicanos: resultados de la Encuesta Nacional de Salud y Nutrición 2006

OBJECTIVE: To estimate the prevalence of overweight, obesity and central adiposity in Mexico, and to explore trends compared to the previous Mexican National Health Survey (ENSA 2000) and to Mexican-Americans. MATERIAL AND METHODS: The Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) was used to describe overweight, obesity and central adiposity. Trends over time were assessed using the ENSA 2000 and by comparing the ENSANUT 2006 results to those of Mexican-Americans using the United States National Health and Nutrition Examination Survey (NHANES) 1999-2000 and 2005-2006. RESULTS: A total of 33023 adults > 20 years old were included; 39.7 percent were found to be overweight and 29.9 percent were found to be obese; 75.9 percent of all adults had abdominal obesity. In Mexico between 2000 and 2006, the combined prevalence of overweight and obesity in adults increased approximately 12 percent. Mexican-Americans showed a higher prevalence of morbid obesity compared to native Mexicans. CONCLUSIONS: Mexico has experienced a rapid increase in the number of adults who have experienced excess weight gain between the years 2000 and 2006.

OBJETIVO: Estimar la prevalencia de sobrepeso, obesidad y adiposidad central en México, y explorar las tendencias, comparándola con la Encuesta Nacional de Salud 2000 (ENSA 2000) y con los mexicano-americanos. MATERIAL Y MÉTODOS: La Encuesta Nacional de Salud y Nutrición 2006 (ENSANUT 2006) fue usada para describir la prevalencia de sobrepeso y obesidad, asi como de adiposidad central. Las tendencias a través del tiempo fueron obtenidas usando la ENSA 2000, y se compararon con datos de la ENSANUT 2006 y con mexicano-americanos participantes de las National Health and Nutrition Examination Survey (NHANES) 1999-2000 y 2005-2006 de EUA. RESULTADOS: De un total de 33023 adultos > 20 años de edad, 39.7 por ciento tuvo sobrepeso y 29.9 por ciento obesidad. El 75.9 por ciento tuvo obesidad abdominal. En México, entre 2000 y 2006 la prevalencia combinada de sobrepeso y obesidad incrementó ~12 por ciento. Los mexicano-americanos mostraron una mayor prevalencia de obesidad mórbida comparada con los mexicanos residentes en México. CONCLUSIONES: México ha experimentado entre los años 2000 y 2006 un rápido incremento en el número de adultos que padecen sobrepeso.

Cardiovascular disease surveillance in Mexicans and Mexican Americans: a tale of two countries

La migración a gran escala que tiene lugar actualmente de México a los Estados Unidos de América origina nuevos retos para la salud pública. Se deben diseñar políticas de salud bien fundamentadas que aborden los problemas emergentes de salud en los estadounidenses de origen mexicano y otras subpoblaciones de los Estados Unidos. En este artículo se describe un enfoque que permite analizar la carga de las enfermedades cardiovasculares (ECV), tanto en mexicanos como en estadounidenses de ascendencia mexicana (en el contexto de la sociedad que acaban de abandonar). Estos datos se analizan también en el contexto de otras poblaciones de ascendencia hispanoamericana. La caracterización rigurosa de la población migrante mexicana permitirá explicar el estado de salud de los estadounidenses de ascendencia mexicana. De manera similar, la copiosa experiencia en salud pública acumulada en los Estados Unidos puede ser útil en la lucha para controlar las ECV en México. El primer paso lógico puede ser alinear los sistemas existentes de datos de los dos países y describir los patrones fundamentales del desenlace y las situaciones de riesgo de la enfermedad.
