The association between hypertensive disorders during pregnancy and maternal and neonatal outcomes: a retrospective claims analysis.

BACKGROUND: Hypertensive disorders during pregnancy continue to increase in prevalence and are associated with several adverse outcomes and future cardiovascular risk for mothers. This study evaluated the association of hypertensive disorders compared to no hypertension during pregnancy with neonatal and maternal outcomes. We then evaluated risk factors associated with progression from a less to more severe hypertensive disorder during pregnancy. METHODS: We conducted a propensity-matched retrospective cohort study utilizing Medicaid claims data from a national insurer. The study population consisted of mothers with and without hypertensive disorders who delivered between 7/1/2016-12/31/2018 and their infants. Hypertensive disorders included gestational hypertension, chronic hypertension, preeclampsia, and superimposed preeclampsia. Propensity score matching was used to match mothers without to those with hypertensive disorders. Regression models were used to compare maternal and neonatal outcomes. Stepwise logistic regression was used to determine characteristics associated with the progression of gestational hypertension to preeclampsia or chronic hypertension to superimposed preeclampsia. RESULTS: We observed the highest risk of cesarean delivery (odds ratio [OR]:1.61 and 1.99) in mothers and preterm delivery (OR:2.22 and 5.37), respiratory distress syndrome (OR:2.39 and 4.19), and low birthweight (OR:3.64 and 9.61) in babies born to mothers with preeclampsia or superimposed preeclampsia compared to no hypertension, respectively (p < 0.05 for all outcomes). These outcomes were slightly higher among chronic or gestational hypertension compared to no hypertension, however, most were not statistically significant. Risk of neonatal intensive care unit utilization was higher among more severe hypertensive disorders (OR:2.41 for preeclampsia, OR:4.87 for superimposed preeclampsia). Obesity/overweight and having a history of preeclampsia during a prior pregnancy were most likely to predict progression from gestational/chronic hypertension to preeclampsia/superimposed preeclampsia. CONCLUSION: Mothers and neonates born to mothers with preeclampsia or superimposed preeclampsia experienced more adverse outcomes compared to those without hypertension. Mothers and neonates born to mothers with gestational hypertension had outcomes similar to those without hypertension. Outcomes for those with chronic hypertension fell in between gestational hypertension and preeclampsia. Obesity/overweight and having a history of preeclampsia during a prior pregnancy were strong risk factors for hypertension progression.

Doula care across the maternity care continuum and impact on maternal health: Evaluation of doula programs across three states using propensity score matching.

Background: This evaluation of doula care emerges at a time when maternal mortality in the U.S. outranks every country in the developed world. Study objectives were to: 1) examine when over the maternity care continuum and with whom (i.e., clinical providers) doula care provides the greatest benefits to clinical health outcomes and health care utilization; and 2) evaluate whether women gain differential benefits from doulas depending upon race/ethnicity and health status. Methods: We conducted a retrospective cohort study using Medicaid medical claims from California, Florida, and a northeastern state (USA) to compare maternal health outcomes between women who did and did not receive doula care between January 1, 2014 and December 31, 2020. We used propensity score matching and logistic regression models to calculate associations between selected health outcomes and doula care. Our analysis included 298 pairs of women matched on age, race/ethnicity, state, socioeconomic status, and hospital type (teaching or non-teaching). Findings: Women who received doula care had 52.9% lower odds of cesarean delivery (OR: 0.471 95% CI: 0.29-0.79) and 57.5% lower odds of postpartum depression/postpartum anxiety (PPD/PPA) (OR: 0.425 95% CI: 0.22-0.82). Doulas who provided care with a clinical team that included a midwife most consistently showed a reduction in odds of cesarean delivery, regardless of the trimester when doula care was received. Women who received doula care during labor and birth, but not necessarily during pregnancy, showed a 64.7% reduction in odds of PPA/PPD (OR: 0.353 95% CI: 0.16-0.78) of PPA/PPD. Interpretation: The use of doulas appears an effective strategy for improving maternal health, especially among socioeconomically vulnerable and marginalized minority populations. Future studies could address research gaps through focusing on the relationship between doula care received in the postpartum period and postpartum health.

Clinical Outcomes and Cost Associated With an Intravascular Microaxial Left Ventricular Assist Device vs Intra-aortic Balloon Pump in Patients Presenting With Acute Myocardial Infarction Complicated by Cardiogenic Shock.

Importance: Intravascular microaxial left ventricular assist device (LVAD) compared with intra-aortic balloon pump (IABP) has been associated with increased risk of mortality and bleeding among patients with acute myocardial infarction (AMI) and cardiogenic shock (CS) undergoing percutaneous coronary intervention (PCI). However, evidence on the association of device therapy with a broader array of clinical outcomes, including data on long-term outcomes and cost, is limited. Objective: To examine the association between intravascular LVAD or IABP use and clinical outcomes and cost in patients with AMI complicated by CS. Design, Setting, and Participants: This retrospective propensity-matched cohort study used administrative claims data for commercially insured patients from 14 states across the US. Patients included in the analysis underwent PCI for AMI complicated by CS from January 1, 2015, to April 30, 2020. Data analysis was performed from April to November 2021. Exposures: Use of either an intravascular LVAD or IABP. Main Outcomes and Measures: The primary outcomes were mortality, stroke, severe bleeding, repeat revascularization, kidney replacement therapy (KRT), and total health care costs during the index admission. Clinical outcomes and cost were also assessed at 30 days and 1 year. Results: Among 3077 patients undergoing PCI for AMI complicated by CS, the mean (SD) age was 65.2 (12.5) years, and 986 (32.0%) had cardiac arrest. Among 817 propensity-matched pairs, intravascular LVAD use was associated with significantly higher in-hospital (36.2% vs 25.8%; odds ratio [OR], 1.63; 95% CI, 1.32-2.02), 30-day (40.1% vs 28.3%; OR, 1.71; 95% CI, 1.37-2.13), and 1-year mortality (58.9% vs 45.0%; hazard ratio [HR], 1.44; 95% CI, 1.21-1.71) compared with IABP. At 30 days, intravascular LVAD use was associated with significantly higher bleeding (19.1% vs 14.5%; OR, 1.35; 95% CI, 1.04-1.76), KRT (12.2% vs 7.0%; OR, 1.88; 95% CI, 1.30-2.73), and mean cost (+$51 680; 95% CI, $31 488-$75 178). At 1 year, the association of intravascular LVAD use with bleeding (29.7% vs 24.3%; HR, 1.36; 95% CI, 1.05-1.75), KRT (18.1% vs 10.9%; HR, 1.95; 95% CI, 1.35-2.83), and mean cost (+$46 609; 95% CI, $22 126-$75 461) persisted. Conclusions and Relevance: In this propensity-matched analysis of patients undergoing PCI for AMI complicated by CS, intravascular LVAD use was associated with increased short-term and 1-year risk of mortality, bleeding, KRT, and cost compared with IABP. There is an urgent need for additional evidence surrounding the optimal management of patients with AMI complicated by CS.

Race and Gender Differences in the Association Between Experiences of Everyday Discrimination and Arterial Stiffness Among Patients With Coronary Heart Disease.

BACKGROUND: Self-reported experiences of discrimination have been linked to indices of cardiovascular disease. However, most studies have focused on healthy populations. Thus, we examined the association between experiences of everyday discrimination and arterial stiffness among patients with a history of myocardial infarction (MI). PURPOSE: We hypothesized that higher reports of discrimination would be associated with greater arterial stiffness and that associations would be more pronounced among Black women, in particular, relative to other race-gender groups, using an "intersectionality" perspective. METHODS: Data were from 313 participants (49.2% female, mean age: 50.8 years) who were 6 months post-MI in the Myocardial Infarction and Mental Stress 2 study. Data were collected via self-reported questionnaires, medical chart review, and a clinic visit during which arterial stiffness was measured noninvasively using pulse wave velocity. RESULTS: Reports of discrimination were highest in Black men and women and arterial stiffness was greatest in Black and White women. After adjustment for demographics and relevant clinical variables, discrimination was not associated with arterial stiffness in the overall study sample. However, discrimination was associated with increased arterial stiffness among Black women but not White women, White men, or Black men. CONCLUSIONS: Despite no apparent association between discrimination and arterial stiffness in the overall study sample, further stratification revealed an association among Black women but not other race-gender groups. These data not only support the utility of an intersectionality lens but also suggest the importance of implementing psychosocial interventions and coping strategies focused on discrimination into the care of clinically ill Black women.

Evaluating different criteria for defining a complete ambulatory blood pressure monitoring recording: data from the Jackson Heart Study.

OBJECTIVE: We determined differences in the prevalence of blood pressure (BP) phenotypes and the association of these phenotypes with left ventricular hypertrophy (LVH) for individuals who fulfilled and did not fulfill various criteria used for defining a complete ambulatory blood pressure monitoring (ABPM) recording. METHODS: We analyzed data for 1141 participants from the Jackson Heart Study. Criteria evaluated included having greater than or equal to 80% of planned readings with more than or equal to one reading per hour (Spanish ABPM Registry criteria), more than or equal to 70% of planned readings with a minimum of 20 daytime and seven nighttime readings (2013 European Society of Hypertension criteria), greater than or equal to 14 daytime and greater than or equal to seven nighttime readings (2003 European Society of Hypertension criteria), more than or equal to 10 daytime and more than or equal to 5 nighttime readings (International Database of Ambulatory Blood Pressure in Relation to Cardiovascular Outcome criteria), and greater than or equal to 14 daytime readings (UK National Institute of Health and Clinical Excellence criteria). RESULTS: Between 45.0% (Spanish ABPM Registry) and 91.8% (UK National Institute of Health and Clinical Excellence) of the participants fulfilled the different criteria for a complete ABPM recording. Across the various criteria evaluated, 55.5-57.8% of participants had nocturnal hypertension and 62.8-66.8% had nondipping systolic BP. Among participants with clinic-measured systolic/diastolic BP of more than or equal to 140/90 mmHg, 22.9-26.5% had white-coat hypertension. The prevalence of daytime, 24-h, sustained, and masked hypertension differed by up to 2% for participants fulfilling each criterion. The association of BP phenotypes with LVH was similar for participants who fulfilled versus those who did not fulfill different criteria (each P>0.05). CONCLUSION: Irrespective of the criteria used for defining a complete ABPM recording, the prevalence of BP phenotypes and their association with LVH were similar.

Chronic kidney disease and incident apparent treatment-resistant hypertension among blacks: Data from the Jackson Heart Study.

It is unclear whether black patients with chronic kidney disease (CKD) vs those without CKD who take antihypertensive medication have an increased risk for apparent treatment-resistant hypertension (aTRH). The authors analyzed 1741 Jackson Heart Study participants without aTRH taking antihypertensive medication at baseline. aTRH was defined as uncontrolled blood pressure while taking three antihypertensive medication classes or taking four or more antihypertensive medication classes, regardless of blood pressure level. CKD was defined as an albumin to creatinine ratio ≥30 mg/g or estimated glomerular filtration rate <60 mL/min/1.73 m2 . Over 8 years, 20.1% of participants without CKD and 30.5% with CKD developed aTRH. The multivariable-adjusted hazard ratio for aTRH comparing participants with CKD vs those without CKD was 1.45 (95% CI, 1.12-1.86). Participants with an albumin to creatinine ratio ≥30 vs <30 mg/g (hazard ratio, 1.44; 95% CI, 1.04-2.00) and estimated glomerular filtration rate of 45 to 59 mL/min/1.73 m2 and <45 vs ≥60mL/min/1.73 m2 (hazard ratio, 1.60 [95% CI, 1.16-2.20] and 2.05 [95% CI, 1.28-3.26], respectively) were more likely to develop aTRH.

Blood Pressure, Antihypertensive Polypharmacy, Frailty, and Risk for Serious Fall Injuries Among Older Treated Adults With Hypertension.

Antihypertensive medication and low systolic blood pressure (BP) and diastolic BP have been associated with an increased falls risk in some studies. Many older adults have indicators of frailty, which may increase their risk for falls. We contrasted the association of systolic BP, diastolic BP, number of antihypertensive medication classes taken, and indicators of frailty with risk for serious fall injuries among 5236 REGARDS study (Reasons for Geographic and Racial Difference in Stroke) participants ≥65 years taking antihypertensive medication at baseline with Medicare fee-for-service coverage. Systolic BP and diastolic BP were measured, and antihypertensive medication classes being taken assessed through a pill bottle review during a study visit. Indicators of frailty included low body mass index, cognitive impairment, depressive symptoms, exhaustion, impaired mobility, and history of falls. Serious fall injuries were defined as fall-related fractures, brain injuries, or joint dislocations using Medicare claims through December 31, 2014. Over a median of 6.4 years, 802 (15.3%) participants had a serious fall injury. The multivariable-adjusted hazard ratio for a serious fall injury among participants with 1, 2, or ≥3 indicators of frailty versus no frailty indicators was 1.18 (95% confidence interval, 0.99-1.40), 1.49 (95% confidence interval, 1.19-1.87), and 2.04 (95% confidence interval, 1.56-2.67), respectively. Systolic BP, diastolic BP, and number of antihypertensive medication classes being taken at baseline were not associated with risk for serious fall injuries after multivariable adjustment. In conclusion, indicators of frailty, but not BP or number of antihypertensive medication classes, were associated with increased risk for serious fall injuries among older adults taking antihypertensive medication.

Cardiovascular Health and Incident Hypertension in Blacks: JHS (The Jackson Heart Study).

Several modifiable health behaviors and health factors that comprise the Life's Simple 7-a cardiovascular health metric-have been associated with hypertension risk. We determined the association between cardiovascular health and incident hypertension in JHS (the Jackson Heart Study)-a cohort of blacks. We analyzed participants without hypertension or cardiovascular disease at baseline (2000-2004) who attended ≥1 follow-up visit in 2005 to 2008 or 2009 to 2012 (n=1878). Body mass index, physical activity, diet, cigarette smoking, blood pressure (BP), total cholesterol, and fasting glucose were assessed at baseline and categorized as ideal, intermediate, or poor using the American Heart Association's Life's Simple 7 definitions. Incident hypertension was defined at the first visit wherein a participant had systolic BP ≥140 mm Hg, diastolic BP ≥90 mm Hg, or self-reported taking antihypertensive medication. The percentage of participants with ≤1, 2, 3, 4, 5, and 6 ideal Life's Simple 7 components was 6.5%, 22.4%, 34.4%, 25.2%, 10.0%, and 1.4%, respectively. No participants had 7 ideal components. During follow-up (median, 8.0 years), 944 (50.3%) participants developed hypertension, including 81.3% with ≤1 and 11.1% with 6 ideal components. The multivariable-adjusted hazard ratios (95% confidence interval) for incident hypertension comparing participants with 2, 3, 4, 5, and 6 versus ≤1 ideal component were 0.80 (0.61-1.03), 0.58 (0.45-0.74), 0.30 (0.23-0.40), 0.26 (0.18-0.37), and 0.10 (0.03-0.31), respectively (Ptrend <0.001). This association was present among participants with baseline systolic BP <120 mm Hg and diastolic BP <80 mm Hg and separately systolic BP 120 to 139 mm Hg or diastolic BP 80 to 89 mm Hg. Blacks with better cardiovascular health have lower hypertension risk.

Clinic and ambulatory blood pressure in a population-based sample of African Americans: the Jackson Heart Study.

Blood pressure (BP) can differ substantially when measured in the clinic versus outside of the clinic setting. Few population-based studies with ambulatory blood pressure monitoring (ABPM) include African Americans. We calculated the prevalence of clinic hypertension and ABPM phenotypes among 1016 participants in the population-based Jackson Heart Study, an exclusively African-American cohort. Mean daytime systolic BP was higher than mean clinic systolic BP among participants not taking antihypertensive medication (127.1[standard deviation 12.8] vs. 124.5[15.7] mm Hg, respectively) and taking antihypertensive medication (131.2[13.6] vs. 130.0[15.6] mm Hg, respectively). Mean daytime diastolic BP was higher than clinic diastolic BP among participants not taking antihypertensive medication (78.2[standard deviation 8.9] vs. 74.6[8.4] mm Hg, respectively) and taking antihypertensive medication (77.6[9.4] vs. 74.3[8.5] mm Hg, respectively). The prevalence of daytime hypertension was higher than clinic hypertension for participants not taking antihypertensive medication (31.8% vs. 14.3%) and taking antihypertensive medication (43.0% vs. 23.1%). A high percentage of participants not taking and taking antihypertensive medication had nocturnal hypertension (49.4% and 61.7%, respectively), white-coat hypertension (30.2% and 29.3%, respectively), masked hypertension (25.4% and 34.6%, respectively), and a nondipping BP pattern (62.4% and 69.6%, respectively). In conclusion, these data suggest hypertension may be misdiagnosed among African Americans without using ABPM.

Cardiovascular Risk Factors and Masked Hypertension: The Jackson Heart Study.

Masked hypertension is associated with increased risk for cardiovascular disease. Identifying modifiable risk factors for masked hypertension could provide approaches to reduce its prevalence. Life's Simple 7 is a measure of cardiovascular health developed by the American Heart Association that includes body mass index, physical activity, diet, cigarette smoking, blood pressure (BP), cholesterol, and glucose. We examined the association between cardiovascular health and masked daytime hypertension in the Jackson Heart Study, an exclusively African American cohort. Life's Simple 7 factors were assessed during a study visit and categorized as poor, intermediate, or ideal. Ambulatory BP monitoring was performed after the study visit. Using BP measured between 10:00 am and 8:00 pm on ambulatory BP monitoring, masked daytime hypertension was defined as mean clinic systolic BP/diastolic BP <140/90 mm Hg and mean daytime systolic BP/diastolic BP ≥135/85 mm Hg. Among the 758 participants with systolic BP/diastolic BP <140/90 mm Hg, 30.5% had masked daytime hypertension. The multivariable-adjusted prevalence ratios for masked daytime hypertension comparing participants with 2, 3, and ≥4 versus ≤1 ideal Life's Simple 7 factors were 0.99 (95% confidence interval [CI], 0.74-1.33), 0.77 (95% CI, 0.57-1.03), and 0.51 (95% CI, 0.33-0.79), respectively. Masked daytime hypertension was less common among participants with ideal versus poor levels of physical activity (ratio, 0.74; 95% CI, 0.56-1.00), ideal or intermediate levels pooled together versus poor diet (prevalence ratio, 0.73; 95% CI, 0.58-0.91), ideal versus poor levels of cigarette smoking (prevalence ratio, 0.61; 95% CI, 0.46-0.82), and ideal versus intermediate levels of clinic BP (prevalence ratio, 0.28, 95% CI, 0.16-0.48). Better cardiovascular health is associated with a lower preva lence of masked hypertension.

Association of Reduced eGFR and Albuminuria with Serious Fall Injuries among Older Adults.

BACKGROUND AND OBJECTIVES: Falls are common and associated with adverse outcomes in patients on dialysis. Limited data are available in earlier stages of CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We analyzed data from 8744 Reasons for Geographic and Racial Differences in Stroke Study participants ≥65 years old with Medicare fee for service coverage. Serious fall injuries were defined as a fall-related fracture, brain injury, or joint dislocation using Medicare claims. Hazard ratios (HRs) for serious fall injuries were calculated by eGFR and albumin-to-creatinine ratio (ACR). Among 2590 participants with CKD (eGFR<60 ml/min per 1.73 m(2) or ACR≥30 mg/g), cumulative mortality after a serious fall injury compared with age-matched controls without a fall injury was calculated. RESULTS: Overall, 1103 (12.6%) participants had a serious fall injury over 9.9 years of follow-up. The incidence rates per 1000 person-years of serious fall injuries were 21.7 (95% confidence interval [95% CI], 20.3 to 23.2), 26.6 (95% CI, 22.6 to 31.3), and 38.3 (95% CI, 31.2 to 47.0) at eGFR levels ≥60, 45-59, and <45 ml/min per 1.73 m(2), respectively, and 21.3 (95% CI, 20.0 to 22.8), 31.7 (95% CI, 27.5 to 36.5), and 42.2 (95% CI, 31.3 to 56.9) at ACR levels <30, 30-299, and ≥300 mg/g, respectively. Multivariable adjusted HRs for serious fall injuries were 0.91 (95% CI, 0.76 to 1.09) and 1.09 (95% CI, 0.86 to 1.37) for eGFR=45-59 and <45 ml/min per 1.73 m(2), respectively, versus eGFR≥60 ml/min per 1.73 m(2) and 1.31 (95% CI, 1.11 to 1.54) and 1.81 (95% CI, 1.30 to 2.50) for ACR=30-299 and ≥300 mg/g, respectively, versus ACR<30 mg/g. Among participants with CKD, cumulative 1-year mortality rates among patients with a serious fall and age-matched controls were 21.0% and 5.5%, respectively. CONCLUSIONS: Elevated ACR but not lower eGFR was associated with serious fall injuries. Evaluation for fall risk factors and fall prevention strategies should be considered for older adults with elevated ACR.

Ambulatory Blood Pressure Monitoring in Individuals with HIV: A Systematic Review and Meta-Analysis.

INTRODUCTION: Abnormal diurnal blood pressure (BP) rhythms may contribute to the high cardiovascular disease risk in HIV-positive (HIV+) individuals. To synthesize the current literature on ambulatory BP monitoring (ABPM) in HIV+ individuals, a systematic literature review and meta-analysis were performed. METHODS: Medical databases were searched through November 11, 2015 for studies that reported ABPM results in HIV+ individuals. Data were extracted by 2 reviewers and pooled differences between HIV+ and HIV-negative (HIV-) individuals in clinic BP and ABPM measures were calculated using random-effects inverse variance weighted models. RESULTS: Of 597 abstracts reviewed, 8 studies with HIV+ cohorts met the inclusion criteria. The 420 HIV+ and 714 HIV- individuals in 7 studies with HIV- comparison groups were pooled for analyses. The pooled absolute nocturnal systolic and diastolic BP declines were 3.16% (95% confidence interval [CI]: 1.13%, 5.20%) and 2.92% (95% CI: 1.64%, 4.19%) less, respectively, in HIV+ versus HIV- individuals. The pooled odds ratio for non-dipping systolic BP (nocturnal systolic BP decline <10%) in HIV+ versus HIV- individuals was 2.72 (95% CI: 1.92, 3.85). Differences in mean clinic, 24-hour, daytime, or nighttime BP were not statistically significant. I2 and heterogeneity chi-squared statistics indicated the presence of high heterogeneity for all outcomes except percent DBP dipping and non-dipping SBP pattern. CONCLUSIONS: An abnormal diurnal BP pattern may be more common among HIV+ versus HIV- individuals. However, results were heterogeneous for most BP measures, suggesting more research in this area is needed.

Injury risk among children in motor vehicle crashes: older versus younger drivers.

AIM: To explore the relationship between injury risk among child occupants involved in motor vehicle collisions according to the age of the vehicle driver. METHODS: The National Automotive Sampling System Crashworthiness Data System 2000-2009 (n = 10 797) was used to identify demographic, vehicle-, collision- and injury-related characteristics among motor vehicle collision occupants ≤15 years of age. The association between the age of the driver (older vs. younger, defined as individuals <50 years of age vs. individuals ≥50 years of age, respectively) and injury occurrence was estimated using logistic regression adjusting for the potentially confounding effect of occupant, vehicle and collision characteristics. RESULTS: Of the child occupants in motor vehicle collisions, 2.9% were driving with an older driver, and approximately 2.9% were injured while driving with a younger driver (odds ratio 1.03; 95% confidence interval 0.55-1.91). After adjusting for child occupant age, gender, restraint use, seat position and vehicle type, there remained no significant association between the age of the driver (older vs. younger) and the risk of injury (odds ratio 0.92; 95% confidence interval 0.49-1.74). CONCLUSIONS: These findings add to the body of literature indicating no difference in injury risk found among children when considering the age of the driver. Research is needed to ascertain the association and further evaluate characteristics more specific to the relationship being explored in this study.

Trends in hypertension prevalence, awareness, treatment, and control among US adults 80 years and older, 1988-2010.

The authors examined trends in systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the prevalence, awareness, treatment, and control of hypertension in 1988-1994 (n=1164), 1999-2004 (n=1,026), and 2005-2010 (n=1048) among US adults 80 years and older in serial National Health and Nutrition Examination Surveys. Hypertension was defined as SBP ≥140 mm Hg, DBP ≥90 mm Hg, or use of antihypertensive medication. Awareness and treatment were defined by self-report and control as SBP/DBP<140/90 mm Hg. Mean SBP decreased from 147.3 mm Hg to 140.1 mm Hg and mean DBP from 70.2 mm Hg to 59.4 mm Hg between 1988-1994 and 2005-2010. The prevalence, awareness, and treatment of hypertension each increased over time. Controlled hypertension increased from 30.4% in 1988-1994 to 53.1% in 2005-2010. The proportion of patients taking 3 classes of antihypertensive medication increased from 7.0% to 30.9% between 1988-1994 and 2005-2010. Increases in awareness, treatment, and control of hypertension and antihypertensive polypharmacy have been observed among very old US adults.

Use of complementary and alternative medicine for eye-related diseases and conditions.

AIM: To determine the prevalence, types and characteristics associated with complementary and alternative medicine (CAM) use to treat eye-related diseases and conditions. MATERIALS AND METHODS: The 2002 and 2007 National Health Interview Survey (NHIS) was used to identify participants, 18 years of age and older, who completed the Adult Alternative Health/Complementary and Alternative Medicine questionnaire. Characteristics for those who reported CAM use for eye diseases and conditions and those who did not were compared; the types of CAM and the eye diseases and conditions for their use were also reported. RESULTS: In 2002, an estimated 0.1% of US adults reported using at least one of eight CAM therapies for eye-related problems; in 2007 the prevalence of CAM use for eye diseases and conditions had increased to 0.3%. In both 2002 and 2007, those who reported CAM use for eye diseases and conditions were more likely to be older, female, white and married. In both 2002 and 2007, the most common types of CAM therapies used were natural herbs and vitamin supplements. Macular degeneration was the most common condition for which CAM therapies were used. CONCLUSIONS: The study suggests that there is a small and perhaps increasing proportion of the US population that uses CAM for eye diseases and conditions. Further research is needed to determine the use and effectiveness of CAM for ophthalmologic purposes.
