Family Health Survey 1999 - Belize

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

The main objectives of the 1999 Family Health Survey - Females of Belize are to have an updated database for urgent use in decisions related to family health. More specifically, the survey will provide urgently needed information on fertility of females, infant and child mortality, family practices, and the use of maternal and child health services in Belize.

The main objectives of the 1999 Family Health Survey of Belizean males are to have an updated database for urgent use in decisions related to male family health. More specifically, the survey will provide urgently needed information on fertility of males, family practices, male attitudes towards various related health issues such as HIV/AIDS and other STIs and other reproductive health issues. There presently exists a dire need for data on male Reproductive Health, among others, and an FHS at this time would meet many of these urgent needs. The major users of the results of this survey will include the Ministry of Health, the BFLA and the Ministries of Human and Economic Development.

Geographic coverage
---------------------------

The survey covered all areas in Belize excluding the Mennonite communities and therefore allows for comparisons between districts as well as between urban and rural areas.

Universe
---------------------------

Females survey:

The survey carried out in 1999 was of females aged 15 to 49 years. This is similar to the survey done in 1991. In both surveys, a scientifically selected sample of women was used. In the 1999 survey, 4,164 women were selected in the final sample from all six (6) districts of the country.

Males survey:

The survey carried out in 1999 was of males aged 15 to 64 years, and is the first such survey to be carried out in the country. Hence, very little comparison can be made. A scientific sample of men between the above ages was used. This sample was representative of all six (6) districts of the country. An interview was done with each selected male in the survey and this provided information on a broad cross section of topics. Some of these topics included the birth history of the man, contraceptive knowledge and use, knowledge of STIs including HIV/AIDS, and behavioural risks. In order to enrich the analysis, basic social and economic characteristics like educational level and employment status were also collected.

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

FEMALE SURVEY:

The sample finally used was a scientific sample, and was selected as follows. The survey sought to interview 3,500 women between the ages of 13 and 49 years i.e. in their childbearing age. It was expected to interview only one eligible female per household even if there was more than one eligible respondent. Preliminary investigations revealed that, to achieve an objective of 3,500 interviews, it would be necessary to target some 6,700 households. It was also necessary to analyse the data at the district and urban/rural levels.

Allowing for a non-response rate of 10% meant that about 7,400 households would have to be selected. The estimated number of households in the country at the time was 46,648. Hence, a sampling fraction of 1/6 was estimated to be necessary to obtain this number of households. To achieve the above, the total number of households in the country was broken up into clusters of approximately 38 households and distributed proportionately among the districts. This resulted in 1,200 clusters being formed for the country. Of this, 1/6 or 200 clusters were selected to be interviewed. This yielded approximately 7,600 households, which is well over the minimum of 7,400 needed to obtain 3,500 successful interviews. It turned out that 4,164 successful interviews were completed, taking into account non-contacts and refusals.

MALE SURVEY:

The sample finally used was a scientific sample, and was selected as follows. The survey sought to interview 2,000 men between the ages of 13 and 64 years. It was expected to interview only one eligible male per household even if there was more than one eligible respondent. Preliminary investigations revealed that to achieve an objective of 2,000 interviews, it would be necessary to target some 2,670 households. It was also necessary to analyze the data at the district and urban/rural levels. Allowing for a non-response rate of 10% meant that about 2,940 households would have to be selected. The estimated number of households in the country at the time was 45,455, excluding the Mennonite settlements of Little Belize in the Corozal District, Blue Creek and Shipyard in Orange Walk and Spanish Lookout in the Cayo District. Hence, a sampling fraction of 1/15 was estimated to be necessary to obtain this number of households.

To achieve the above, the total number of households in the country was broken up into clusters of approximately 30 households and distributed proportionately among the districts. This resulted in 1,524 clusters being formed for the country. Of this, 1/15 or 98 clusters were selected to be interviewed. This yielded approximately 2,940 households which is the minimum needed to obtain 2,000 successful interviews. It turned out that only 1,773 successful interviews were completed, taking into account non-contacts and refusals.

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

From the outset, it was realized that efforts must be exerted to update the 1991 survey as a minimum. However, it was strongly felt that some expansion of depth, if not scope, could also be done. A preparatory committee comprising representation from the Ministry of Health, the BFLA, UNICEF and the CSO was established, and one of this committee's first tasks was to put together a suitable questionnaire to collect the required information. Contacts with the CDC through the person of Dr. Paul Stupp and with Mr. Stan Terrel of the regional programme on HIV/AIDS were extremely beneficial in guiding the discussions on the final questionnaire. These two gentlemen provided samples of both males and females questionnaires which enriched the committee's deliberations, and afforded a hybrid questionnaire in the end, tailored to meet the needs of Belize. The final questionnaire was then translated into Spanish, the second language of Belize. Spanish-speaking interviewers administered the questionnaire in Spanish among the respondents who preferred to be interviewed in this language.

摘要
---------------------------------
1999年家庭健康调查的主要目标是构建一个用于紧急决策的家庭健康数据库。具体而言，该调查旨在提供关于女性生育、婴儿和儿童死亡率、家庭习惯以及在伯利兹使用母亲和儿童健康服务的迫切所需信息。

伯利兹男性1999年家庭健康调查的主要目标是构建一个用于紧急决策的男性家庭健康数据库。具体而言，调查将提供关于男性生育、家庭习惯、男性对各种相关健康问题（如HIV/AIDS和其他性传播感染）的态度以及其他生殖健康问题的迫切所需信息。目前，对男性生殖健康数据的需求尤为迫切，此时进行的FHS将满足许多这些紧急需求。该调查结果的主要使用者包括卫生部、BFLA以及人力资源和经济部。

地理覆盖范围
---------------------------------
该调查覆盖了伯利兹的所有地区，不包括门诺教社区，因此可以比较各区的数据，以及城市和农村地区之间的数据。

调查范围
---------------------------------
女性调查：
1999年进行的调查针对的是15至49岁的女性。这与1991年的调查相似。在这两次调查中，都使用了科学选择的女性样本。在1999年的调查中，从全国六个（6）区的所有女性中选择了4,164名女性作为最终样本。

男性调查：
1999年进行的调查针对的是15至64岁的男性，这是该国首次进行此类调查。因此，可比较的数据非常有限。使用了上述年龄范围内的男性科学样本。该样本代表了全国六个（6）区的所有男性。对调查中选定的每位男性进行了访谈，这提供了关于广泛主题的信息。其中一些主题包括男性的出生史、避孕知识的了解和使用、对性传播感染（包括HIV/AIDS）的了解以及行为风险。为了丰富分析，还收集了基本的社会和经济特征，如教育水平和就业状况。

抽样程序
---------------------------------
女性调查：
最终使用的样本是一个科学样本，其选择方式如下。调查旨在采访13至49岁之间的3,500名女性（即她们的生育年龄）。预计每个家庭中只有一名符合条件的女性受访者，即使有多名符合条件的受访者也是如此。初步调查显示，为了实现3,500次访谈的目标，需要针对大约6,700户家庭。还必须在区和城市/农村水平上分析数据。

考虑到10%的未响应率，意味着需要选择大约7,400户家庭。当时该国估计的家庭数量为46,648。因此，估计的抽样比例为1/6，这是获得上述家庭数量的必要条件。为了实现上述目标，全国的家庭总数被划分为约38户家庭的集群，并按比例分配到各区。这导致了全国形成1,200个集群。其中，1/6或200个集群被选中进行访谈。这产生了大约7,600户家庭，远超过获得3,500次成功访谈所需的最小数量7,400。结果，完成了4,164次成功的访谈，考虑到未接触和拒绝的情况。

男性调查：
最终使用的样本是一个科学样本，其选择方式如下。调查旨在采访2,000名13至64岁的男性。预计每个家庭中只有一名符合条件的男性受访者，即使有多名符合条件的受访者也是如此。初步调查显示，为了实现2,000次访谈的目标，需要针对大约2,670户家庭。还必须在区和城市/农村水平上分析数据。

考虑到10%的未响应率，意味着需要选择大约2,940户家庭。当时该国估计的家庭数量为45,455，不包括科罗萨尔区的小伯利兹门诺教社区、橙沃克的蓝色溪流和造船厂以及凯约区的西班牙瞭望台。因此，估计的抽样比例为1/15，这是获得上述家庭数量的必要条件。

为了实现上述目标，全国的家庭总数被划分为约30户家庭的集群，并按比例分配到各区。这导致了全国形成1,524个集群。其中，1/15或98个集群被选中进行访谈。这产生了大约2,940户家庭，这是获得2,000次成功访谈所需的最小数量。结果，只完成了1,773次成功的访谈，考虑到未接触和拒绝的情况。

研究工具
---------------------------------
从一开始，就意识到必须努力更新1991年的调查，作为最低限度。然而，强烈感觉到如果不在范围上，至少在深度上也可以进行一些扩展。由卫生部、BFLA、联合国儿童基金会和CSO代表组成的筹备委员会被建立，该委员会的第一个任务之一是制定一份合适的问卷，以收集所需的信息。通过保罗·斯托普博士与CDC的联系以及与区域HIV/AIDS项目斯坦·特雷尔先生的联系，对最终问卷的讨论极为有益。这两位先生提供了男性和女性问卷的样本，丰富了委员会的讨论，并最终形成了一份混合问卷，旨在满足伯利兹的需求。最终问卷随后被翻译成西班牙语，这是伯利兹的第二语言。说西班牙语的访谈员在喜欢用这种语言接受采访的受访者中用西班牙语进行了问卷。
