Pediatric Nutrition Surveillance System (PedNSS)

The Children's Medical Services (CMS) Branch released the 2006 PedNSS Annual Reports in CHDP Information Notice 07-D. The information notice provides a description of PedNSS reports and instructions for how to complete Performance Measure 6 using these reports.

PedNSS is a child based public health surveillance system that is produced by the Centers for Disease Control and Prevention (CDC).  It primarily monitors indicators of nutritional status: short stature, underweight, overweight, obesity, anemia (low hemoglobin/hematocrit), low birthweight and high birthweight. Body Mass Index (BMI)-for-age percentile for children over 2 years of age is used to identify overweight, obesity and underweight prevalence.  Prevalence of “smoking in household” is a newly collected health indicator and is reported in 2006 PedNSS reports.  Breastfeeding prevalence is not collected in California and therefore it is only reported nationally.  The prevalence rates of all nutrition/health indicators are reported by multiple categories of age and race/ethnicity among low income, at-risk infants, children and adolescents who participate in publicly funded health programs.



Nationwide, pediatric nutrition surveillance has been conducted continuously since 1973. California began participating in PedNSS continuously since 1988.


Target Population

Low-income, at-risk children, birth through 19 years of age, with emphasis on birth to 5 years of age.


Design and Methods

Primary indicators of nutritional status (hematology, BMI-for-age percentile, height-for-age, and weight-for-height) are monitored in California using clinic data from CHDP exams. Data are collected in medical offices/clinics and recorded on the CHDP Confidential Screening/Billing Report form (PM 160). The CHDP Confidential Screening/Billing Report form is submitted for payment and program reporting and serves as serving as California’s PedNSS data source. The CMS Branch transmits the data to CDC for inclusion in the national surveillance system. Annual reports are produced by CDC and made available on the CHDP webpage.


Technical Assistance

CMS Branch staff provides technical assistance in interpretation of data for local CHDP Programs. For additional technical information/explanations about PedNSS methodology, go to CDC’s website and click on "How to."



A variety of entities use child based public health surveillance systems.  Local CHDP programs use PedNSS to identify at-risk groups; determine local program priorities; monitor population trends; disseminate prevalence data to providers and community groups; complete performance measures and evaluate program interventions.  CHDP providers may use county prevalence data to identify at-risk patients and common nutrition risks and for prioritizing patient intervention.  Other public programs such as, WIC, maternal and child health programs and schools may use state and county prevalence data to supplement community assessments, identify at-risk groups and common nutrition risks, program planning, development of policies, monitor population trends, evaluate program interventions and obtain funding.
