Khayelitsha Integrated Family Survey 2002-2005 - South Africa

Abstract
---------------------------

From 2002-2005, the study collected data in Limpopo Province, at the Agincourt Demographic Surveillance Site, and in Khayelitsha, a township outside Cape Town, through the auspices of Philani Nutrition and Development Project.
Integrated health and economic surveys are used to investigate the links between health status and economic status. This survey collected data on a range of traditional and non-traditional measures of well-being, including income and consumption, measures of health status (including mental health), morbidity, crime, social connectedness, intra-household relationships, and direct hedonic measures of well-being. In 2002, there was a cross-sectional study conducted in Agincourt. Random household selection was stratified by age-eligibility for the Old Age Pension and nationality. In 2004, there was a second cross-sectional study conducted in Agincourt. Random selection of households was stratified on the basis of both citizenship, (South African or Mozambican), and whether or not a death had occurred in the household. The study in Khayelitsha was longitudinal. Part 1 of the first wave was conducted in 2002 and part 2 of the first wave was conducted in 2003. In 2004, the households who had been interviewed in 2002 were re-interviewed (if they were willing and if they could be found), for part 1 of the second wave. In 2005, the households who were interviewed in 2003 were re-interviewed, for part 2 of the second wave. For all of the studies, the methodology for conducting the surveys was the same. The questions varied some from year to year. The crosswalk identifies these variations.

Sampling procedure
---------------------------

Khayelitsha 2002 and 2004
In 1994, Ingrid le Roux conducted a census of dwellings in Khayelitsha and surveyed a random sample of households from that census. We used the random sample of households surveyed in 1994 to draw a random sample of households to survey in 2002, with a follow up survey in 2004. In total we interviewed members of 203 households in 2002, and 165 households in 2004. The majority of interviews in 2002 were conducted between May and September. The majority in 2004 were conducted between March and July.

Khayelitsha 2003 and 2005
The second part of the Khayelitsha panel is a stratified random sample of 300 households. The township was divided into sampling blocks, and aerial photographs were used to count the number of dwellings in each block. 15 sampling blocks were then selected, with probability proportional to the number of dwellings in each block. A total of 20 households were then randomly sampled within each block. In 2005, 264 of the original 2003 households, and 7 split off households from the original 300 were interviewed. The majority of interviews in 2003 were conducted between March and September. The majority in 2005 were conducted between February and July.

Research instrument
---------------------------

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.

自2002年至2005年，本研究在林波波省的阿金库特人口监测站点，以及开普敦郊外的凯莱利塔斯小镇，在菲拉尼营养与发展项目的赞助下收集数据。通过综合健康和经济调查，探究健康状况与经济状况之间的联系。该调查收集了关于福祉的传统与非传统衡量指标的数据，包括收入和消费、健康状况指标（包括心理健康）、发病率、犯罪率、社会联系、家庭内部关系以及福祉的直接快乐度量。2002年，在阿金库特进行了一项横断面研究。随机家庭选择基于老年金资格的年龄适宜性和国籍。2004年，在阿金库特进行了一次第二次横断面研究。家庭的随机选择基于公民身份（南非或莫桑比克），以及家庭中是否发生过死亡。在凯莱利塔斯的研究是纵向的。第一波的第一部分于2002年进行，第一波的第二部分于2003年进行。2004年，对2002年接受过采访的家庭进行了重新采访（如果他们愿意并且能够找到的话），以进行第二波的第一部分。2005年，对2003年接受过采访的家庭进行了重新采访，以进行第二波的第二部分。对于所有的研究，进行调查的方法是相同的。问题每年都有所变化。交叉表确定了这些变化。

凯莱利塔斯2002年和2004年
1994年，英格丽德·勒·鲁克斯对凯莱利塔斯的住宅进行了普查，并对普查中的随机样本家庭进行了调查。我们使用1994年调查的随机家庭样本，抽取2002年调查的随机家庭样本，并在2004年进行了后续调查。总共在2002年采访了203个家庭的成员，在2004年采访了165个家庭的成员。2002年的大多数采访在5月至9月之间进行。2004年的大多数采访在3月至7月之间进行。
凯莱利塔斯2003年和2005年
凯莱利塔斯面板的第二部分是300个家庭的分层随机样本。该小镇被划分为抽样单元，并使用航空照片计算每个单元的住宅数量。然后选择了15个抽样单元，其选择概率与每个单元的住宅数量成比例。然后在每个单元内随机抽取了20个家庭。2005年，对2003年的原始200个家庭中的264个家庭以及原始300个家庭中的7个分家进行了采访。2003年的大多数采访在3月至9月之间进行。2005年的大多数采访在2月至7月之间进行。

从khhm那里收集关于已故家庭成员和搬家的家庭成员的汇总信息。从2003年开始的研究年份，详细询问了最近一次死亡对家庭的影响。
对khhm提出了关于生活条件的详细问题：是否有厕所，是否有自来水，是否有炉灶，有电话。询问了关于家庭支出的问题：医疗保健上是如何花钱的，孩子的学校费用等。
成人问卷：
2002年有两个独立的成人问卷。一个是针对18至54岁成人的问卷；另一个是针对55岁及以上的成人问卷。在随后的研究年份中，有一个针对18岁及以上成人的问卷。家庭中的每个可用的、愿意的成人都会回答这些问题。包括关于年龄、婚姻状况、在世子女数量和已故子女数量的问题。详细询问了他们的收入来源和支出。对于老年成人，有关于养老金和补助的问题，对于母亲有关于育儿补助的问题。个人描述了他们多年来所从事的工作类型，他们赚了多少钱以及他们是如何花这些钱的。提出了详细的健康问题；涵盖了身体和心理健康问题。对接受采访的个人进行了身体测量：他们的身高、体重、腰围；血压和脉搏。
