Regional Tables from the 2005-2006 Maternal and Infant Health Assessment (MIHA) surveys

MO-07-0140 MIHA

Introduction to the MIHA Survey and Explanation of Terms/Regional Tables

The California Maternal and Infant Health Assessment (MIHA) is an annual, statewide-representative survey of women who recently gave birth. It is completed via the mail, with telephone follow-up to non-respondents.  MIHA is administered in English and Spanish only.

The MIHA survey data have been linked to birth certificate information and weighted to reflect sampling design.  The sample was stratified by race, education and region (PDF)within California; African-American women were oversampled. There were too few American Indian women in the study to examine them separately.  Age, parity and region (PDF)of residence come from birth certificate information linked to MIHA, and are not asked in MIHA.  All other variables are taken from the MIHA responses.  The numbers reported are unweighted, but the percents are weighted.  Weighted percents take into account the sample stratification and the oversampling.  Some measures had too small a number (unweighted numerator < 10) to calculate a stable, representative percentage and are indicated by an asterisk (*) only.  95% CI represents "95% Confidence Interval," which means that 95% of the time the true value should be between these two values.  However, please remember that this survey is self-administered, which may affect some answers.  Thus, one should not expect estimates from the MIHA survey to be identical to surveys that collect data through in-person interview or telephone call.     

Regional Tables

The statewide tables include indicators/outcomes by region.  The regional tables provide demographics by indicator/outcome within each region.  The topics of the regional tables are a subset of those presented in the statewide tables; the regional table numbers (A1, A3, etc.) match those of the statewide tables for easy comparison.  Two years of MIHA data (2005 and 2006) were analyzed together for the regional tables (the statewide tables represent 2006 only), in order to provide sample sizes large enough to calculate a greater number of stable percentages.
