Project description:BackgroundOlder adults frequently have several chronic health conditions which require multiple medications. We illustrated trends in prescription medication use over 20 years in the United States, and described characteristics of older adults using multiple medications in 2009-2010.MethodsParticipants included 13,869 adults aged 65 years and older in the National Health & Nutrition Examination Survey (1988-2010). Prescription medication use was verified by medication containers. Potentially inappropriate medications were defined by the 2003 Beers Criteria.ResultsBetween 1988 and 2010 the median number of prescription medications used among adults aged 65 and older doubled from 2 to 4, and the proportion taking ≥5 medications tripled from 12.8% (95% confidence interval: 11.1, 14.8) to 39.0% (35.8, 42.3).These increases were driven, in part, by rising use of cardioprotective and antidepressant medications. Use of potentially inappropriate medications decreased from 28.2% (25.5, 31.0) to 15.1% (13.2, 17.3) between 1988 and 2010. Higher medication use was associated with higher prevalence of functional limitation, activities of daily living limitation, and confusion/memory problems in 2009-2010, although these associations did not remain after adjustment for covariates. In multivariable models, older age, number of chronic conditions, and annual health care visits were associated with increased odds of using both 1-4 and ≥5 medications. Additionally, body mass index, higher income-poverty ratio, former smoking, and non-black non-white race were associated with use of ≥5 medications.ConclusionsPrescription medication use increased dramatically among older adults between 1988 and 2010. Contemporary older adults on multiple medications have worse health status compared with those on less medications, and appear to be a vulnerable population.

Project description:The study evaluated the change in the prevalence of airflow obstruction in the U.S. population 40-79 years of age from years 1988-1994 to 2007-2010.Spirometry data from two representative samples of the U.S. population, the National Health and Nutrition Examination Surveys (NHANES) conducted in 1988-1994 and 2007-2010, were used. The American Thoracic Society/European Respiratory Society (ATS/ERS) criteria were used to define airflow obstruction.Based on ATS/ERS criteria, the overall age-adjusted prevalence of airflow obstruction among adults aged 40-79 years decreased from 16.6% to 14.5% (p < 0.05). Significant decreases were observed for the older age category 60-69 years (20.2% vs. 15.4%; p < 0.01), for males (19.0% vs. 15.4%; p < 0.01), and for Mexican American adults (12.7% vs. 8.4%; p < 0.001). The prevalence of moderate and more severe airflow obstruction decreased also (6.4% vs. 4.4%; p < 0.01). Based on ATS/ERS criteria, during 2007-2010, an estimated 18.3 million U.S. adults 40-79 years had airflow obstruction, 5.6 million had moderate or severe airflow obstruction and 1.4 million had severe airflow obstruction.The overall age-adjusted prevalence of airflow obstruction among U.S. adults aged 40-79 years decreased from 1988-1994 to 2007-2010, especially among older adults, Mexican Americans, and males.

Project description:This study aimed to describe trends in prevalence, awareness, treatment, and control in hypertension in Chengdu from 2000 to 2010. Two community-based cross sectional surveys were conducted among those aged 40-79 years in 2000 (n = 4850) and 2010 (n = 5456). Demographic characteristics, blood pressure (BP) and associated risk factors were examined. Mean systolic and diastolic BP increased from 117.8 ± 33.9 to 132.1 ± 21.2 mmHg (P < 0.001), and 75.3 ± 19.1 to 79.3 ± 11.2 mmHg (P < 0.001) over past decade, respectively. The prevalence of hypertension increased from 27.7 to 29.4% (P < 0.001). Awareness increased from 37.7 to 42.5% (P < 0.001). The overall treatment rate increased from 20.9 to 28.0% (P < 0.0001), while among subjects aware of hypertension, treatment increased from 46.9 to 65.8% (P < 0.001). In hypertensives, control increased from 6.8 to 6.9% (P = 0.6684). Nevertheless, in hypertensives aware and treated, control decreased from 32.5 to 24.3% (P = 0.020). Hypertension prevalence increased in the last decade, while awareness, treatment and control remained considerably low in Chengdu.

Project description:ContextFor more than 20 years, primary prevention of coronary heart disease has included strategies intended to improve overall serum lipid concentrations among youths.ObjectiveTo examine trends in lipid concentrations among youths from 1988-1994 through 2007-2010.Design, setting, and participantsCross-sectional analysis of serum lipid concentrations among 16,116 youths aged 6 to 19 years who participated in the nationally representative National Health and Nutrition Examination Survey during 3 time periods: 1988-1994, 1999-2002, and 2007-2010.Main outcome measuresAmong all youths, mean serum total cholesterol (TC), non-high-density lipoprotein cholesterol (non-HDL-C), high-density lipoprotein cholesterol (HDL-C); and among adolescents only, low-density lipoprotein cholesterol (LDL-C) and geometric mean triglyceride levels. Trends in adverse lipid concentrations are reported for TC levels of 200 mg/dL and greater, non-HDL-C levels of 145 mg/dL and greater, HDL-C levels of less than 40 mg/dL, LDL-C levels of 130 mg/dL and greater, and triglyceride levels of 130 mg/dL and greater.ResultsAmong youths aged 6 to 19 years between 1988-1994 and 2007-2010, there was a decrease in mean TC (from 165 mg/dL [95% CI, 164-167] to 160 mg/dL [95% CI, 158-161]; P < .001) and a decrease in the prevalence of elevated TC (from 11.3% [95% CI, 9.8%-12.7%] to 8.1% [95% CI, 6.7%-9.5%]; P = .002). Mean HDL-C significantly increased between 1988-1994 and 2007-2010, but the prevalence of low HDL-C did not change. Mean non-HDL-C and prevalence of elevated non-HDL-C both significantly decreased over the study period. In 2007-2010, 22% (95% CI, 20.3%-23.6%) of youths had either a low HDL-C level or high non-HDL-C, which was lower than the 27.2% (95% CI, 24.6%-29.7%) in 1988-1994 (P = .001). Among adolescents (aged 12-19 years) between 1988-1994 and 2007-2010, there was a decrease in mean LDL-C (from 95 mg/dL [95% CI, 92-98] to 90 mg/dL [95% CI, 88-91]; P = .003) and a decrease in geometric mean triglycerides (from 82 mg/dL [95% CI, 78-86] to 73 mg/dL [95% CI, 70-76]; P < .001). Prevalence of elevated LDL-C and triglycerides between 1988-1994 and 2007-2010 also significantly decreased.ConclusionsBetween 1988-1994 and 2007-2010, a favorable trend in serum lipid concentrations was observed among youths in the United States but almost 1 in 10 had elevated TC in 2007-2010.

Project description:BackgroundThis study uses data from the World Health Organization's Study on Global Ageing and Adult Health (SAGE) to examine patterns of hypertension prevalence, awareness, treatment and control for people aged 50 years and over in China, Ghana, India, Mexico, the Russian Federation and South Africa.MethodsThe SAGE sample comprises of 35 125 people aged 50 years and older, selected randomly. Hypertension was defined as ≥140 mmHg (systolic blood pressure) or ≥90 mmHg (diastolic blood pressure) or by currently taking antihypertensives. Control of hypertension was defined as blood pressure below 140/90 mmHg on treatment. A person was defined as aware if he/she was hypertensive and self-reported the condition.ResultsPrevalence rates in all countries are broadly comparable to those of developed countries (52.9%; range 32.3% in India to 77.9% in South Africa). Hypertension was associated with overweight/obesity and was more common in women, those in the lowest wealth quintile and in heavy alcohol consumers. Awareness was found to be low for all countries, albeit with substantial national variations (48.3%; range 23.3% in Ghana to 72.1% in the Russian Federation). This was also the case for control (10.2%; range 4.1% in Ghana to 14.1% India) and treatment efficacy (26.3%; range 17.4% in the Russian Federation to 55.2% in India). Awareness was associated with increasing age, being female and being overweight or obese. Effective control of hypertension was more likely in older people, women and in the richest quintile. Obesity was associated with poorer control.ConclusionsThe high rates of hypertension in low- and middle-income countries are striking. Levels of treatment and control are inadequate despite half those sampled being aware of their condition. Since cardiovascular disease is by far the largest cause of years of life lost in these settings, these findings emphasize the need for new approaches towards control of this major risk factor.

Project description:Joint National Committee goal blood pressure for all adults was <140/<90 mm Hg or lower from 1984 to 2013. Adults aged ?60 years (older) have mainly isolated systolic hypertension, with major trials attaining systolic blood pressure <150 but not <140 mm Hg. The main objective was to assess changes in hypertension control to <140/<90 mm Hg in younger (aged <60 years) and older adults and <150/<90 mm Hg in the latter.National Health and Nutrition Examination Surveys (NHANES) 1988 to 1994, 1999 to 2004, and 2005 to 2010 were analyzed in adults aged ?18 years. From 1988 to 1994 to 2005 to 2010, hypertension control to <140/<90 mm Hg improved in older (31.6% to 53.1%; P<0.001) and younger (45.7% to 55.9%; P<0.001) patients. The age gap in control declined from 14.1% (P<0.01) in 1988 to 1994 to 2.8% (P=0.13) in 2005 to 2010. Better hypertension control reflected increased percentages of older (55.6% to 77.5%) and younger (34.6% to 54.7%) patients on treatment and treated older (45.7% to 64.9%) and younger (56.8% to 73.4%) patients controlled (all P<0.001). Control to <150/<90 mm Hg rose from 48.8% to 69.9% in older adults. Antihypertensive medication number and percentages on ?3 medications increased in both age groups but increased more in older patients (P<0.01). Blood pressure control was higher in both age groups with ?2 healthcare visits per year and on statin therapy.The age gap in hypertension control to <140/<90 mm Hg was virtually eliminated in 2005 to 2010 as clinicians intensified therapy, especially in older patients in whom isolated systolic hypertension predominates, controlling 70% to <150/<90 mm Hg. More frequent healthcare visits and the use of statin therapy may improve hypertension control in all adults.

Project description:ObjectiveAs the most important risk factors of cardiovascular disease, pre-hypertension and hypertension are important public health challenges. Few studies have focused on the trends of pre-hypertension and hypertension specifically for the aging population in China. Given the anticipated growth of the elderly population in China, there is an urgent need to document the conditions of pre-hypertension and hypertension in this aging population.MethodsWe conducted two cross-sectional surveys of Chinese adults aged ≥60 years in 2001 and 2010. A total of 2,272 (943 males, 1,329 females) and 2,074 (839 males, 1,235 females) participants were included in the two surveys, respectively.ResultsThe age- and sex-standardized prevalence of hypertension significantly increased from 60.1% to 65.2% from the 2001 to the 2010 survey. Among the participants with hypertension, the awareness, treatment and control of hypertension all significantly increased from 69.8% to 74.5%, 50.3% to 63.7%, and 15.3% to 30.3%, respectively, from 2001 to 2010. A logistic regression showed that a higher education level, a higher BMI, a family history of hypertension and doctor-diagnosed cardiovascular disease were significantly associated with hypertension awareness and treatment.ConclusionHypertension prevalence increased rapidly between the years surveyed. Although the awareness, treatment and control of hypertension improved significantly, the values of these variables remained low. More attention should be given to the elderly because the population is aging worldwide, and urgent action, optimal treatment approaches and proper public health strategies must be taken to prevent and manage hypertension.

Project description:Trends in the prevalence and control of diabetes defined by hemoglobin A1c (HbA1c) levels are important for health care policy and planning.To update trends in the prevalence of diabetes, prediabetes, and glycemic control.Cross-sectional.NHANES (National Health and Nutrition Examination Survey) in 1988-1994 and 1999-2010.Adults aged 20 years or older.We used calibrated HbA1c levels to define undiagnosed diabetes (?6.5%); prediabetes (5.7% to 6.4%); and, among persons with diagnosed diabetes, glycemic control (<7.0% or <8.0%). Trends in HbA1c categories were compared with fasting glucose levels (?7.0 mmol/L [?126 mg/dL] and 5.6 to 6.9 mmol/L [100 to 125 mg/dL]).In 2010, approximately 21 million U.S. adults aged 20 years or older had total confirmed diabetes (self-reported diabetes or diagnostic levels for both fasting glucose and calibrated HbA1c). During 2 decades, the prevalence of total confirmed diabetes increased, but the prevalence of undiagnosed diabetes remained fairly stable, reducing the proportion of total diabetes cases that are undiagnosed to 11% in 2005-2010. The prevalence of prediabetes was lower when defined by calibrated HbA1c levels than when defined by fasting glucose levels but has increased from 5.8% in 1988-1994 to 12.4% in 2005-2010 when defined by HbA1c levels. Glycemic control improved overall, but total diabetes prevalence was greater and diabetes was less controlled among non-Hispanic blacks and Mexican Americans compared with non-Hispanic whites.Cross-sectional design.Over the past 2 decades, the prevalence of total diabetes has increased substantially. However, the proportion of undiagnosed diabetes cases decreased, suggesting improvements in screening and diagnosis. Among the growing number of persons with diagnosed diabetes, glycemic control improved but remains a challenge, particularly among non-Hispanic blacks and Mexican Americans.National Institutes of Health.

Project description:BackgroundObesity is a risk factor for asthma. However, it is unclear if increased obesity prevalence contributed to rising childhood asthma prevalence.ObjectiveTo assess if population-level changes in weight status impacted asthma prevalence over time.MethodsUsing nationally representative 1988-2014 National Health and Nutrition Examination Survey data for 40 644 children aged 2-19 years, we analyzed asthma trends by weight status (body mass index age-specific percentiles determined using measured weight and height). Logistic regression and population attributable fraction were used to assess the association between obesity and asthma prevalence.ResultsAlthough obesity was a risk factor for asthma throughout the period, asthma prevalence increased only among children with normal weight; there was no interaction between weight status and time. The population attributable fraction for overweight/obesity rose from 8.5% in 1988-1994 to 11.9% in 2011-2014, but this increase was not significant (P = 0.44).ConclusionsTogether, these data do not support a contribution of obesity trends to asthma prevalence trends.

Project description:IntroductionWe conducted this study among older adults with the following objectives: (1) To find out the prevalence, awareness, treatment and control of hypertension, (2) To understand the factors associated with hypertension prevalence and control.MethodsA mixed-methods study employing a sequential explanatory design was conducted with a survey of 300 participants aged ≥60 years, and 15 in-depth interviews. Blood Pressure (BP) and waist circumference were measured using standard protocol. Survey data were analysed using univariate and multivariate procedures. In-depth interviews were analysed employing thematic analysis.ResultsHypertension prevalence was 72.3% (95% CI = 67.1-77.2), 68.2% (CI = 61.8-74.2) were aware, 65.4% (CI = 59.0-71.6) were treated and 24% (CI = 18.6-29.9) achieved adequate control. Inadequate physical activity [(adjusted odds ratio (AOR)] = 2.34; CI = 1.19-4.59), current alcohol use (AOR = 2.28; CI = 1.06-4.91) and self-reported diabetes (AOR = 2.02; CI = 1.15-3.52) were associated with hypertension prevalence. Those who reported diabetes (AOR = 2.72, CI = 1.34-5.55), with education level up to high school (AOR = 2.58, CI = 1.11-6.00) and who were in the age group 60-70 years (AOR = 2.14, CI = 1.09-4.20) were more likely to have controlled hypertension compared to their counterparts. From the in-depth interviews it was found that availability and accessibility of services, family support, financial wellbeing, habits and beliefs and conducive environment played a role in hypertension diagnosis and management.DiscussionPrevalence of hypertension was high in this population along with poor control. Efforts are required to improve hypertension control focussing on older adults with low education and those who are aged 70 years and above.
