MEC YOUTH QUESTIONNAIRE (Except DIS)                        
                                                                                
                                                                                
     The MEC Youth Questionnaire was administered to examinees aged 8-16        
     years in the mobile examination center (MEC).  Conducted by a trained      
     interviewer, the automated questionnaire was administered in a private     
     setting to ensure confidentiality due to the sensitive nature of some      
     of the sections.  The questionnaire included sections on physical          
     activity, tobacco use, reproductive health, selected conditions,           
     medicine/vitamin usage, food frequency, alcohol/drug use, and the          
     Diagnostic Interview Schedule (DIS).  Because this component was           
     administered in the examination center, the MEC examination sample         
     weight (WTPFEX6) should be used for data analysis.  For more               
     information on the use of sample weights in NHANES III data analysis,      
     refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS,      
     1996b).                                                                    
                                                                                
     Several portions of the questionnaire were asked only of specific age      
     or gender groups, and check items are included as variables in this        
     file to indicate these subgroups.  For example, reproductive health        
     was asked of boys aged 15-16 years and girls aged 10-16 years.             
     Medicine/vitamin use, food frequency, and alcohol/drug use were            
     asked of boys and girls aged 12-16 years.  The DIS was asked of            
     adolescents aged 15-16 years.  The DIS was edited and documented           
     separately (see Diagnostic Interview Schedule).                            
                                                                                
     A subset of questions from the MEC Youth Questionnaire were                
     administered as the MEC Proxy Questionnaire to the parents or              
     guardians of children aged 2 months-11 years.  Questions on medicine,      
     vitamin, and mineral usage, selected health conditions, and WIC            
     program participation from the two questionnaires can be combined          
     for an analysis of youths 2 months-16 years of age (see MEC Proxy          
     Questionnaire).                                                            
                                                                                
     Data processing and editing were performed for consistency of              
     responses within the sections of the questionnaire.  Notes have been       
     provided for variables that were standardized or recoded or those          
     that require additional comments.  The notes reference the questions, by   
     section and number, from the questionnaires which can be found in the      
     Plan and Operation of the National Health and Nutrition Examination        
     Survey, 1988-1994 (NCHS, 1994; U.S. DHHS, 1996b).

     MYPB6R:  Number of cigarettes smoked per day                               
                                                                                
          This variable was created from the question B6.  The actual           
          number of cigarettes smoked per day and a range of cigarettes         
          smoked per day were the allowable answers.  The variable includes     
          the mean number of cigarettes smoked per day derived from the         
          range as well as the actual number of cigarettes smoked per day.

          This variable was created from the question B7 when the data were     
          not missing.  If B7 was missing, this variable used the estimated     
          number of years the respondent smoked the amount reported in B6.      
          The number was derived by subtracting the age that the respondent     
          started smoking regularly from the age at the MEC interview.

          This variable was created from the two-part question (quantity

          This recode was derived to include a listing of all birth control     
          pills that were specified in question C9.  It includes both birth     
          control pills with original codes from the chart that the             
          respondents were shown as well as those that were not included on     
          the chart but that were specified by the respondents.  See the        
          Appendix in the MEC Adult Questionnaire for the code listing.         
                                                                                
                                                                                
     MYPC13R:  Age at time of first live birth                                  
                                                                                
          Question C13 (age at time of first live birth) was only asked of      
          women who had more than one live birth.  To prevent redundant         
          questions, women who had one live birth were only asked question      
          C14, "Age at the time of the last live birth."   This variable,       
          MYPC13R, was created to include responses for women who had only      
          one live birth and women who had multiple births.  For women who      
          had only one live birth, their responses to question C14 were coded   
          into MYPC13R.  For women who had multiple births, their responses     
          to question C13 were coded into MYPC13R.

          This variable was created from the two-part question (quantity        
          and unit) C23 using the conversion factor 12 months/year.

          This variable was derived from questions C10 and C27.                 
          Respondents who reported a pregnancy (question C10) were not          
          asked whether they had ever had sexual intercourse (question C27)     
          as the response was implicit.  Therefore, MYPC27R was coded as        
          "Yes" for respondents who reported a pregnancy in C10 and coded as    
          the response in C27 for all other respondents.                        
                                                                                
                                                                                
     MYPC28:  Age at first sexual intercourse                                   
                                                                                
          The question did not ask about first consensual sexual experience.    
          Therefore, responses of first intercourse at very young ages were     
          retained after reviewing comments made during the interview (e.g.,    
          reports of rape or incest).
