Questionnaires
Household Questionnaire:
The most knowledgeable household member (khhm) was the initial person interviewed within the household. He or she would list all of the members of the household. This list of household members was then used as a guide for the entire interview process. The khhm first answered questions about the individual members of the household: age, gender, education, marital status, is that person?s partner in the household, is that person's parent in the household. Additionally, the khhm was asked about the source and amount of income of each household member.
Summary information was gathered from the khhm about the household members who had died and the household members who had moved. In study years starting in 2003, detailed questions were posed about the effect the most recent death had on the household.
Detailed questions were asked of the khhm about the living conditions: is there a toilet, is there running water, do you have a stove, a phone. Questions about household expenditures were asked: how is the money spent on health care, on children?s schooling expenses, etc.
Adult Questionnaire:
In 2002, there were two separate adult questionnaires. One questionnaire was for adults whose ages fell between 18 and 54; the second questionnaire was for adults 55 years old and up. In subsequent study years there was one questionnaire for adults 18 and older. Every adult from the household, who was available and willing to, answered these questions. Questions about age, marital status, number of living children, and number of children who have died were included. Detailed questions were asked about their sources of income and their expenditures. For older adults, there were questions about pensions and grants, for mothers there were questions about childcare grants. Individuals described the type of jobs they held over the years, how much money they earned and how they spent that money. Detailed health questions were posed; both physical and mental health issues were covered. Physical measurements were taken of the individuals interviewed: their height, weight, waist size; blood pressure and pulse.
Child Questionnaire:
The parent or guardian of each child was questioned about the child. Questions included: birth weight, history of breastfeeding and health of the child. With the parent?s or guardian?s permission, the child?s height and weight were measured. Detailed information was recorded about the child's immunization history.
