  • Description:
    The Pregnancy Nutrition Surveillance System (PNSS) is a public health surveillance system that monitors the prevalence of nutrition problems, behavioral risk factors, and birth outcomes among low-income women who are enrolled in public health programs in states or U.S. territories or through Indian Tribal Organizations (ITOs). The goal of the PNSS is to collect, analyze, and disseminate surveillance data to guide public health policy and action. The collected data are used to set public health priorities and to plan, implement, and evaluate nutrition programs for pregnant women. This report summarizes PNSS data from 2009 and highlights data trends from 2000 through 2009. he PNSS collects demographic data about maternal age, race and ethnicity, education level, household income, migrant status, and participation in food and medical assistance programs. Information about a mother’s height; weight before, during, and after pregnancy; hemoglobin and hematocrit levels; parity; medical care during pregnancy; and enrollment in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) also is collected. In addition, the PNSS collects information about patterns of maternal smoking and alcohol consumption 3 months before and during pregnancy. Data collected about infants include date of birth, birthweight, and breastfeeding status. Data are collected at the clinic level, aggregated at the state level, and then submitted to the Centers for Disease Control and Prevention (CDC) for analysis. The PNSS generates surveillance reports for each contributor and for the nation, based on results from participating contributors. A contributor is defined as a state, U.S. territory, or ITO. In 2009, the PNSS included 31 states, the District of Columbia, 5 ITOs, and 1 U.S. territory (Figure 1). These contributors provided more than 1.3 million records to the system, nearly double the number of records collected in 2000. This gain is largely due to the increased number of contributors to the PNSS. Fluctuations in the number of contributors and records can affect trends. The number of PNSS contributors shown differs slightly from year to year because some contributors did not provide data every year during the 10-year period from 2000 through 2009 (Table 1). The WIC program has consistently been the primary source of PNSS data, contributing nearly 100% of the records in 2009.
