Health Indicator Report of Breastfeeding - exclusive, 8+ weeks

Breast milk is the most complete nutrition for a new baby as it offers a perfect combination of proteins, fats, carbohydrates, and vitamins essential for optimum growth, health, and development. It also provides active defense against many early-life diseases including ear and respiratory infections, sudden infant death syndrome, skin, and stomach problems as well as lowers the risk for many diseases later in life including obesity, type 2 diabetes, and asthma. Breastfeeding is also associated with health benefits to mothers, decreasing the risk for type 2 diabetes, breast cancer, and ovarian cancer.


The percentages reported above have been produced by weighting the sample so that the results better represent the Hawaii population. Numerator and denominator data have been rounded to the nearest 100. In cases where the numerator is 49 or less, it is displayed as 50. Statistical Stability--Relative standard error, or RSE, is the standard error expressed as a proportion of the point estimate. Stable is displayed when the RSE is below 0.30. Unstable is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance). Very unstable is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decision making. Problems with statistical instability typically occur when there is a small number of health events in a small population. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate. Suppression of Estimates--According to CDC PRAMS guidelines, a minimum of 30 respondents must answer the question in order for it to be reported. Where the number of respondents is below 30, or the RSE is greater than 0.50, ** will appear in the table.

Data Interpretation Issues

PRAMS uses a two-stage, stratified random sampling method to identify the sample. The sampling frame is drawn from birth certificates. Each month, approximately 200 women who are 2 to 4 months post-delivery are chosen. The sample includes only residents of Hawaii who had a recent live birth in the state. The results are weighted to ensure accurate representation of the population.


Percent of mothers who exclusively breastfed their infants for 8 or more weeks based on a series of questions.


The numerator includes mothers who offered only breast milk to their babies for the first 8 weeks or more based on a series of questions.


The denominator includes all survey respondents except those with missing, don't know, and refused answers.
