% of Pregnant Women in WIC who were pre-pregnancy overweight (BMI 25-<30) The percent of pregnant women enrolled in the WIC program with a body mass index (BMI) between 25 and 30. BMI is defined as weight in kilograms divided by height in meters squared w/h2.
*** DEFINITION CHANGE *** :
For the reporting period 2007-2009 the categories for pre-pregnancy Body Mass Index (BMI) are based on the 2009 Institute of Medicine (IOM) report, "Weight Gain During Pregnancy". The BMI cut-off values specified by the (IOM) in 2009 are used to classify women as underweight (BMI <18.5), normal weight (BMI 18.5 to 24.9), overweight (BMI 25.0 to 29.9), or obese (BMI ≥30.0). The prevalence estimates are not directly comparable to prior years when the 1990 IOM standards were used to classify pre-pregnancy BMI. See: http://www.iom.edu/Reports/2009/Weight-Gain-During-Pregnancy-Reexamining-the-Guidelines.aspx and http://www.cdc.gov/pednss/what_is/pnss_health_indicators.htm#Maternal Health Indicators
Note, the definitions for previous years were: underweight-BMI <19.8, overweight-BMI 26-29, obese-BMI >29.
% of Pregnant Women in WIC who were pre-pregnancy obese (BMI 30+) The percent of pregnant women enrolled in the WIC program with a body mass index (BMI) 30 or greater. BMI is defined as weight in kilograms divided by height in meters squared w/h2.

% of overweight children aged 2-4 participating in WIC The percent of children participating in the WIC program who are overweight. Overweight is defined as between the 85th and 95th percentile based on body mass index (BMI) for age. BMI is defined as weight in kilograms divided by height in meters squared w/h2.
% of obese children aged 2-4 participating in WIC The percent of children participating in the WIC program who are obese. Obese is defined as at or above the 95th percentile based on body mass index (BMI) for age. BMI is defined as weight in kilograms divided by height in meters squared w/h2.
% of children in WIC, 0-4 years, viewing TV <=2 hours per day The percent of children participating in the WIC program who watch television no more than 2 hours per day.
% of WIC mothers breastfeeding at 6 months The percent of mothers with children participating in the WIC program who were breastfeeding their infants at 6 months of age.
Behavioral Risk Indicators
Source: Expanded Behavior Risk Factor Surveillance System (Expanded BRFSS)
Source: The Expanded Risk Factor Surveillance System (Expanded BRFSS) augments the CDC Behavioral Risk Factor Surveillance System (BRFSS) and is a random-digit-dialed telephone survey among adults 18 years of age and older representative of the non-institutionalized civilian population with landline telephones living in New York State. The goal of Expanded BRFSS is to collect county-specific data on preventive health practices, risk behaviors, injuries and preventable chronic and infectious diseases. Survey data collection occurred in 58 geographic areas of New York State, including each of the 57 counties outside of New York City and New York City (5 counties) as a single area.

% of adults who are overweight or obese (BMI=>25) (age-adjusted) The percent of survey respondents (18+ years of age) with body mass index (BMI) greater than 24.9. BMI is defined as weight in kilograms divided by height in meters squared w/h2.
% of adults engaged in some type of physical activity (age-adjusted) The percent of survey respondents (18+ years of age) who report they participated in some type of physical activity during their leisure time at least one day in the last 30 days.

Mortality-Related Indicators Source: Vital Records NYSDOH Bureau of Biometrics and Health Statistics - Information is extracted from death certificates. When percentages are calculated, records with missing information for the indicator of interest are excluded from the calculation. Rates are calculated using population estimates provided by the US Census Bureau. ICD-10 codes are used for cause of death. Rates are age-adjusted based on the 2000 US Census population.

Cardiovascular Disease Mortality (Rate per 100,000) age-adjusted The number of deaths due to cardiovascular disease per 100,000 population. The ICD-10 codes used for cardiovascular disease are: I00-I99.
Cerebrovascular Disease (Stroke) Mortality (Rate per 100,000) age-adjusted The number of deaths due to cerebrovascular disease per 100,000 population. The ICD-10 codes used for cerebrovascular disease are: I60-I69.
Diabetes Mortality (Rate per 100,000) age-adjusted The number of deaths due to diabetes per 100,000 population. The ICD-10 codes used for diabetes are: E10-E14.
Hospitalization-Related Indicators Source: Statewide Planning and Research Cooperative System-SPARCS NYSDOH Bureau of Biometrics and Health Statistics- Data on hospitalizations are collected through the hospital inpatient discharge data system. Each hospitalization receives an ICD-9 code at discharge which indicates the primary reason for the hospitalization. Data are not available on events that did not result in a hospitalization, such as cases that were only treated in a hospital emergency room.
