Vital and health statistics. Series 11, Data from the National Health Survey最新文献

Objectives: This report presents national estimates of dietary intakes of macronutrients, micronutrients, and other dietary constituents for persons 2 months and older, by sociodemographic variables.

Methods: The third National Health and Nutrition Examination Survey (NHANES III) (1988-94), the source of these data, was designed to provide information on the health and nutritional status of the civilian noninstitutionalized U.S. population. The analytic sample for these analyses included 29,105 participants with complete and reliable dietary recalls.

Results: This report provides mean, median, and standard error of the mean dietary intake data for the U.S. population, 1988-94. Dietary intake estimates were derived from NHANES III 24-hour recall data. Foods reported during the survey were coded using the U.S. Department of Agriculture (USDA) Survey Nutrient Database (SNDB) and the University of Minnesota Nutrition Coordinating Center (NCC) data. Food composition values for macronutrients, vitamins, minerals, and other food components are based on SNDB and NCC data.

Conclusions: Data on nutrient intakes are a crucial piece of information toward the determination of total dietary intake. Together with anthropometric and laboratory data, information on nutrient intake can be used to assess nutritional status and elucidate the relationship between nutrition and health.

Objectives: This report presents estimates of the prevalence of use of dietary supplements among the U.S. population by various demographic and descriptive characteristics, the number of products taken, and types of supplements taken by broad product-type categories.

Methods: The third National Health and Nutrition Examination Survey (NHANES III) is a nationally representative survey of the civilian, noninstitutionalized U.S. population, 2 months of age or over. Participants were asked about their use of vitamin and/or mineral supplements in the past month. Many also reported use of other dietary supplements.

Results: Approximately 40 percent of the population took dietary supplements during the month prior to the interview. Females (44 percent) were more likely to take a supplement than males (35 percent). Non-Hispanic white persons (43 percent) were more likely to take supplements than non-Hispanic black persons (30 percent) and Mexican American persons (29 percent). Children 1-5 years of age were major users of supplements. Among adults 20 years of age and older, there was a trend toward increasing use of dietary supplements with age. Higher levels of education, income, and self-reported health status were all positively related to supplement use. Sixty-seven percent of supplement users took only one supplement, with the majority of them taking a combination vitamin/mineral product (46 percent).

Conclusions: A substantial proportion of the U.S. population takes vitamins, minerals, and/or other dietary supplements.

Objectives: This report presents national estimates of serum and red blood cell (RBC) folate and serum vitamin B12 distributions for persons 4 years and over, by sociodemographic variables.

Methods: The third National Health and Nutrition Examination Survey (NHANES III) (1988-94), provides information on the health and nutritional status of the civilian noninstitutionalized U.S. population. The analytic sample included 23,378 participants with serum folate data, 23,082 with RBC folate data, and 11,851 with serum vitamin B12 data.

Results: The mean serum and RBC folate concentrations are 7.2 and 196 nanograms per milliliter (ng/mL), respectively, and the mean serum vitamin B12 concentration is 518 picograms per milliliter (pg/mL). Non-Hispanic white people have higher mean serum and RBC folate concentrations than non-Hispanic black or Mexican American people. Serum vitamin B12 concentrations are lowest for older adults, and non-Hispanic black people have higher serum B12 concentrations than non-Hispanic white individuals. Only approximately 3 percent of the population has a serum B12 concentration less than 200 pg/mL.

Conclusions: Inadequate folate status may be more prevalent among non-Hispanic black and Mexican American people. Data also suggest a modest prevalence of low serum B12 concentrations. Future assessments of folate and vitamin B12 status will be important to evaluate the impact of a recently enacted fortification policy.

This report presents descriptive and analytic data for serum total cholesterol, cholesterol lipoproteins, and triglycerides for adults 20-74 years of age by age, sex, and selected subgroups of the population at risk of developing coronary heart disease. This information is from the second National Health and Nutrition Examination Survey, which was conducted during the years 1976-80.

This report presents descriptive data for clinical chemistry profiles by age and sex. This information is from the Hispanic Health and Nutrition Examination Survey, a sample survey of selected groups of civilian noninstitutionalized Hispanic persons residing in the United States. The survey was conducted during 1982-84.

This report presents descriptive data for serum lipids and lipoproteins by age, sex, and selected socioeconomic variables. This information is from the Hispanic Health and Nutrition Examination Survey, a sample survey of selected groups of civilian noninstitutionalized Hispanic persons residing in selected area of the United States, that was conducted during the period 1982-84.
