2 Childhood Asthma Prevalence Report in Nevada 2006 Preface The Childhood Asthma Prevalence Report in Nevada for the year 2006 consists of four sections: (a) Demographics of Nevada Households and Children 2006, (b) Lifetime and Current Childhood Asthma 2006, (c) Lifetime and Current Childhood Asthma by Adult Respondent Information 2006 and (d) Lifetime and Current Childhood Asthma by Household Information This special report provides a summary of the information collected from Nevada s Behavioral Risk Factor Surveillance System (BRFSS) throughout the year 2006 on the topics of the Childhood Asthma optional module. Generally, the BRFSS collects data on a variety of health conditions, risk factors, preventive health measures, and demographic variables. The objective of this special report is to study and assess the needs of the Child Health Population.. Asthma is a breathing disorder caused by ongoing inflammation of the airways, common in both adults and children. The impact of asthma has increased over the recent years to become the most common diseases in the U.S. today. In fact asthma is the most common chronic childhood illness and one of the leading causes of school absence, emergency room visits, and hospitalizations. For child health assessment, Nevada has included questions by proxy on the BRFSS of the year 2006 to assess childhood asthma prevalence using a Random Child Selection module. The goal of the Parent/Guardian self-reported proxy for children is to enable Maternal and Child Health programs to get a reliable measure of childhood asthma prevalence through the BRFSS in Nevada. The Nevada BRFSS questions about childhood asthma addressed 1) the number of children in the household who had ever been diagnosed with asthma, and 2) the number of children who still had asthma. Information was provided by a randomly selected adult respondent in all households with at least one child under age 18. For Table 2 and 3, the child weight with post-stratification was used: _CHILDWT= (_FINALWT*CHILDREN/ (POSTSTR*NUMADULT))*POSTSTR2, where CHILDREN is the number of children in the household and POSTSTR2 is the new post-stratification coefficient on the total number of children in the state.). For Table 5 the household weight multiplied by the child-level post stratification Coefficient was used: CHILDWT_HH= (_FINALWT/ (POSTSTR*NUMADULT))*POSTSTR2, where POSTSTR and NUMADULT are variables from BRFSS that represent the adult-level post-stratification and the number of adults in the household, respectively. In all other Tables the regular BRFSS weight (_FINALWT) was used. Note that in all Tables Denominator includes respondents excluding those who responded "do not know/not sure" or who refused to respond, N denotes response numbers and % denotes weighted prevalence rates (row percentages unless specified otherwise).
