Interviewer instructions

The purpose of these questions about sexual intercourse is to determine the respondent's exposure to pregnancy, since fertility levels are directly related to the frequency of intercourse. Condom use also is of interest because it can help reduce the risk of transmission of AIDS and other sexually transmitted infections. These questions may be embarrassing for some respondents; therefore, ask them in a matter-of-fact voice. A common reaction for people who are embarrassed is to giggle or laugh. If you laugh in return or act as if you are embarrassed too, the respondent may think that the questions are not serious. Make sure you maintain a serious attitude.

If the respondent says she does not know how old she was when she first had intercourse, probe by relating it to how old she was when she first got married or had her first child. However, when doing this probing, be certain not to assume that the first time she had sex was at the time of her first marriage. If she says her first time was when she started living with her (first) husband/partner, record it as such by selecting 'FIRST TIME WHEN STARTED LIVING WITH (FIRST) HUSBAND/PARTNER.' Check to make sure that the age at first intercourse and the age at first birth (calculated by subtracting the woman's year of birth from the year of birth of the woman's first child) are consistent. The age at first intercourse should not be later than her age at first birth. If her age at intercourse (Q. 616) is older than her age at first birth, then either the year of birth of her first child is wrong or her age at first intercourse is wrong. Check to see which date is wrong and correct it. If she has never had intercourse, select'NEVER HAD SEXUAL INTERCOURSE'.
