Use of nutritional supplements for the prevention and treatment of hypercholesterolemia

Who Uses CAM? A Narrative Review of Demographic Characteristics and Health Factors Associated with CAM Use

Complementary and Alternative Medicines (CAM) are used by an extensive number of patients in the UK and elsewhere. In order to understand this pattern of behavior, it is helpful to examine the characteristics of people who use CAM. This narrative review collates and evaluates the evidence concerning the demographic characteristics and health status factors associated with CAM use in community-based non-clinical populations. A systematic literature search of computerized databases was conducted, and published research papers which present evidence concerning associations between CAM use and demographic and health characteristics are discussed and evaluated. The evidence suggests that people who use CAM tend to be female, of middle age and have more education. In terms of their health, CAM users tend to have more than one medical condition, but might not be more likely than non-users to have specific conditions such as cancer or to rate their own general health as poor. The multivariate studies that have been conducted suggest that both demographic and health characteristics contribute independently to CAM use. In conclusion, demographic characteristics and factors related to an individual's health status are associated with CAM use. Future research is needed to address methodological limitations in existing studies.

Medication use for diabetes, hypertension, and hypercholesterolemia from 1988-1994 to 2001-2006

The objective of this study was to compare rates of use of medications for diabetes, hypertension, and hypercholesterolemia between 1988-1994 and 2001-2006 and determine whether increased medication use may be partly attributable to nonadherence to healthy lifestyle habits. This study analyzed and compared data from two different time periods in the National Health and Nutrition Examination Survey (NHANES). Disease prevalence rates increased 23% (P < 0.01), and medication use increased 121% (P < 0.05) over the study's period. Diabetes medication use increased from 5.3% to 8.7%, antihypertension medication from 23.0% to 32.4%, and cholesterol-lowering medication from 4.5% to 16.7% (all P < 0.05). By race, diabetes medication use increased most among Hispanics (7.2% to 13.2%), antihypertension use increased most among non-Hispanic blacks (30.8% and 39.6%), and cholesterol medication increased most in non-Hispanic whites (4.9% to 17.8%) (all P < 0.05). Greater adherence to healthy lifestyle habits was associated with less use of medication (P < 0.01). Medication use for diabetes, hypertension, and hypercholesterolemia has increased between 1988-1994 and 2001-2006 and is greater in people with fewer healthy lifestyle habits.

Factors affecting the use of dietary supplements by Korean adults: data from the Korean National Health and Nutrition Examination Survey III

We investigated the use of dietary supplements among adult Korean consumers, including associations involving sociodemographic variables, lifestyle characteristics, health-related factors, and dietary supplement use. The data were derived from the 2005 third Korean National Health and Nutrition Examination data among 4,775 adults (1,983 men and 2,792 women) regarding medical examinations and diet. In general, 21.8% of the male and 32.0% of the female respondents used dietary supplements regularly. Dietary supplement users tended to reside in large cities and to have higher monthly incomes. People with bone diseases consumed 1.71 times higher (95% confidence interval [CI] 1.19 to 2.46) amounts of supplements than those without such diseases. Among dietary supplement users, female respondents expressed a preference for carbohydrates (adjusted odds ratio [OR] 3.79; 95% CI 1.33 to 10.79). The intake rates for vitamin/mineral complexes tended to increase with age (P for trend 0.007) and respondents earning higher incomes expressed a preference for minerals, vitamin/mineral complexes, and terpenes. Carbohydrate use decreased among those with higher education levels: high school graduates were 0.48 times (95% CI 0.23 to 0.99) and those with college or above were 0.24 times (95% CI 0.07 to 0.83) more likely to use carbohydrates. Nonsmokers (OR 2.63; 95% CI 1.68 to 4.13), nondrinkers (OR 1.73; 95% CI 1.09 to 2.73), and those with bone disease (OR 2.19; 95% CI 1.24 to 3.86) expressed a preference for vitamins. Those who had been diagnosed with a chronic disease showed a preference for terpenes (OR 2.81; 95% CI 1.03 to 7.68). These results indicate that dietary supplement use might be affected by certain sociodemographic, lifestyle, and health characteristics.
