PedNSS

""The Pediatric Nutrition Surveillance System (PedNSS) is a public health surveillance system that monitors the nutritional status of low-income children in federally funded maternal and child health programs. Data on birthweight, breastfeeding, anemia, short stature, underweight, overweight, and obesity are collected for children who attend public health clinics for routine care, nutrition education, and supplemental food. Data are collected at the clinic level then aggregated at the state level and submitted to the Centers for Disease Control and Prevention (CDC) for analysis. A national nutrition surveillance report is produced by using PedNSS data. Surveillance reports also are produced for each contributor, defined as a state, U.S. territory, or Indian Tribal Organization (ITO). In 2008, a total of 51 contributors, including 43 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands and ITOs, participated in PedNSS (Figure 1). These contributors submitted more than 8,165,000 records for children from birth to age 5 to the system--nearly 3 million more records than in 1999. This increase is due largely to an increase in the number of contributors to the PedNSS. Fluctuations in the number of contributors or the demographic characteristics of the contributors' populations can affect trends. The number of PedNSS contributors differs slightly from year to year because some contributors do not provide data every year during the 10-year period from 1999 through 2008. Data for the 2008 PedNSS were collected from children enrolled in federally funded programs that serve low-income children. These programs include the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) (85.3%) and non-WIC programs (14.7%) such as the Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program and the Maternal and Child Bureau Title V program. .

Anthropometric reference data for children and adults: United States, 2003-2006

"Objective: This report presents national anthropometric reference data for all ages of the U.S. population in 2003-2006, adding to results published previously from 1960-2002. Methods: Data are from the National Health and Nutrition Examination Survey (NHANES), a complex, stratified, and multistage probability sample of the civilian, noninstitutionalized U.S. population. Anthropometry measurements were obtained from 19,593 survey participants. The anthropometric measures included weight, height, recumbent length, circumferences, limb lengths, and skinfold thickness measurements. Results: The tables in this report include weighted population means, standard errors of the means, and selected percentiles of body measurement values. Because measurements varied by sex and age (as well as race and ethnicity in adults), results are reported by these subgroups. Conclusions: These latest NHANES data add to the knowledge about trends in child growth and development and trends in the distribution of body measurements, such as weight and height, in the U.S. population.

Mean systolic and diastolic blood pressure in adults aged 18 and over in the United States, 2001-2008

OBJECTIVE: This report presents estimates for the period 2001-2008 of means and selected percentiles of systolic and diastolic blood pressure by sex, race or ethnicity, age, and hypertension status in adults aged 18 and over. METHODS: Demographic characteristics were collected during a personal interview, and blood pressures were measured during a physician examination. All estimates were calculated using the mean of up to three measurements. The final analytic sample consisted of 19,921 adults aged 18 and over with complete data. Examined sample weights and sample design variables were used to calculate nationally representative estimates and standard error estimates that account for the complex design, using SAS and SUDAAN statistical software. RESULTS: Mean systolic blood pressure was 122 mm Hg for all adults aged 18 and over; it was 116 mm Hg for normotensive adults, 130 mm Hg for treated hypertensive adults, and 146 mm Hg for untreated hypertensive adults. Mean diastolic blood pressure was 71 mm Hg for all adults 18 and over; it was 69 mm Hg for normotensive adults, 75 mm Hg for treated hypertensive adults, and 85 mm Hg for untreated hypertensive adults. There was a trend of increasing systolic blood pressure with increasing age. A more curvilinear trend was seen in diastolic blood pressure, with increasing then decreasing means with age in both men and women. Men had higher mean systolic and diastolic pressures than women. There were some differences in mean blood pressure by race or ethnicity, with non-Hispanic black adults having higher mean systolic and diastolic blood pressures than non-Hispanic white and Mexican-American adults, but these differences were not consistent after stratification by hypertension status and sex. CONCLUSIONS: These estimates of the distribution of blood pressure may be useful for policy makers who are considering ways to achieve a downward shift in the population distribution of blood pressure with the goal of reducing morbidity and mortality related to hypertension.by Jacqueline D.

Biological variation of hematology tests based on the 1999-2002 National Health and Nutrition Examination Survey

Objective--Biological variation consists of between-person (BP) and within-person (WP) variation. Estimates of WP coefficients of variation (CVw) and BP coefficients of variation (CVg) for hematology laboratory tests were estimated from the 1999-2002 National Health and Nutrition Examination Survey (NHANES). Methods--NHANES is a survey of the civilian noninstitutionalized U.S. population that uses a stratified, multistage probability design. Between- and within-person variations were estimated for 18 hematology tests. For WP variation, a nonrandom sample was obtained with a median of 17 days between two test measurements. Between-person variation was estimated from the WP sample and additional participants were matched for age group, gender, and race and ethnicity to the WP sample. Results--The BP and WP variations were estimated on as many as 2,496 and 852 sample participants, respectively. Mean corpuscular hemoglobin concentration had the lowest CVg (2.25% for men and 2.40% for women), and mean corpuscular volume had the lowest CVw (0.31% for men and 0.37% for women). The index of individuality (CVw /CVg) ranged from 0.06 for mean corpuscular volume for men and women to 0.62 for segmented neutrophil number for men, and 0.55 for segmented neutrophil percent for women. Women had higher CVw compared with men for hematocrit, hemoglobin, mean corpuscular volume, red blood cell count, and red blood cell distribution width. Several hematology tests' CVw also differed by age group, including mean corpuscular volume; eosinophil, lymphocyte and segmented neutrophil percent; monocyte and segmented neutrophil number; white blood cell count; and red blood cell distribution width.by David A.
