Background: Female genital mutilation (FGM) usually undertaken between the ages of 1-9 years and is widely practised in some part of Africa and by migrants from African countries in other parts of the world. Laws prohibit FGM in almost every country. FGM can cause immediate complications (pain, bleeding and infection) and delayed complications (sexual, obstetric, psychological problems). Several factors have been associated with an increased likelihood of FGM. In Burkina Faso, the prevalence of FGM appears to have increased in recent years. Methods. We investigated social, demographic and economic factors associated with FGM in Burkina Faso using the 2003 Demographic Health Survey (DHS). The DHS is a nationally representative cross-sectional survey (multistage stratified random sampling of households) of women of reproductive age (15-49 years). Associations between potential risk factors and the prevalence of FGM were explored using 2 and t-tests and Mann Whitney U-test as appropriate. Logistic regression modelling was used to investigate social, demographic and economic risk factors associated with FGM. Main outcome measures. i) whether a woman herself had had FGM; ii) whether she had one or more daughters with FGM. Results: Data were available on 12,049 women. Response rates by region were at least 90%. Women interviewed were representative of the underlying populations of the different regions of Burkina Faso. Seventy seven percent (9267) of the women interviewed had had FGM. 7336 women had a daughter of whom 2216 (30.2%) had a daughter with FGM and 334 (4.5%) said that they intended that their daughter should have it. Univariate analysis showed that age, religion, wealth, ethnicity, literacy, years of education, household affluence, region and who had responsibility for health care decisions in the household had (RHCD) were all significantly related to the two outcomes (p < 0.01). Multivariate analysis stratified by religion mainly confirmed these findings, however, education is significantly associated with a reduced likelihood of FGM only for Christian women. Conclusions and Policy implications. Factors associated with FGM are varied and complex. Younger women and those from specific groups and religions are less likely to have had FGM. A higher level of education may be protective for women from certain religions. Policies should capitalize on these findings and religious leaders should be involved in continuing programmes of action. © 2011 Karmaker et al; licensee BioMed Central Ltd.
The Demographic Health Surveys (DHS) are periodic cross sectional health surveys funded by USAID (the U.S. Agency for International Development's) Bureau for Global Health. The DHS includes a number of modules on demographics and household affluence; fertility, reproductive health, maternal and child health; nutrition, and knowledge and practice related to HIV/AIDS [12]. Surveys allow for an optional additional series of questions about FGM [13]. Since the year 2000, when these optional questions were added as part of the DHS, the prevalence of FGM in women in 14 African countries has been found to range between 1% in Cameroon in 2004 to 97% in Egypt in 2000. The history of the development of the FGM questionnaire has been discussed elsewhere [13]. Briefly, DHS surveys collect data from nationally-representative probability samples of households and from adult women (age 15-49) and men in the sampled household. In general, surveys use a two-stage cluster sampling design, with over-sampling of certain categories of respondents. Response rates tend to vary across sampling domains and sample weights are used to obtain nationally representative estimates of indicators. DHS surveys yield nationally representative estimates of FGM for women age 15 to 49 in the survey countries. In the countries where the prevalence of FGM is of concern, a module of FGM Questions is added to the women's questionnaire. The questions are designed to generate information on prevalence rates and types of FGM for the women themselves and for their daughters. Respondents' attitudes towards FGM are also collected. Since 2000, UNICEF's Multiple Indicator Cluster Surveys (MICS) have used a similar module to collect information on FGM in selected countries [13]. Both DHS and MICS surveys provide FGM prevalence data. Female respondents are asked if they have ever heard of FGM; then those who have heard of the practice are asked about their own experience of it. The responses to these questions are used to calculate national prevalence rates of FGM [13]. Experts generally assume that women respond truthfully when asked about their own experience. If bias exists in some of the responses, it has not been documented. It is hypothetically possible that some women may say not admit to having undergone FGM in countries where the practice has been forbidden, but no solid evidence of this has been found. Few empirical studies dealing with FGM in Sub-Saharan Africa have been conducted. Although, there is now an increased amount of literature on the practice of FGM. Most of the literature deals with descriptive statistics and on issues of the origin, types, and justifications for the practice but little has been devoted to its patterns and mediating factors. Freymeyer et. al. 2007 [14] used the 2003 Nigerian DHS to explore attitudes towards FGM in Nigerian. Also using empirical data from the DHS, Kandala et al. 2010 [15] have published work on spatial risk factors for FGM in Nigeria. The DHS survey methods in Burkina Faso are described in detail elsewhere [12] A nationally representative cross-sectional survey of women of reproductive age (15-49 years) was identified using a stratified random two-stage cluster sample of households by enumeration area, to reflect the rural-urban ratio. 400 (of 11,000) enumeration districts were selected (90 urban and 310 rural). 9 470 households in these districts were selected (2340 urban and 7130 rural) and members of 9097 household successfully interviewed. Data collection was undertaken between June and December 2003 by face to face interview with women aged 15-49 in each selected household and with men aged 15-59 in every third household. Topics covered in the women's questionnaire included demographics: age, region, ethnicity, religion, education, literacy, nutrition, and fertility, family planning, and HIV/AIDS risk factors. Topics covered in the household questionnaire included who in the household had responsibility for health care decisions (RHCD); and a number of household characteristics allowing for a calculation of household affluence using an asset index (access to drinking water, toilet facilities, cooking fuel, consumer items (television, bike/car); wall/flooring material. Households were subsequently divided into quintiles using this asset index. The module on FGM included questions on whether the woman herself had undergone FGM; and whether if she had daughters they had also undergone the practice (Table (Table1)1) or whether she intended that they should. Distribution of factors analysed in Female Genital Mutilation (FGM) study in Burkina Faso (DHS 2003) * RHCD Responsibility for health care decisions Chi-square test was used for categorical data and Mann-Whitney test for continuous data. Data analysis was undertaken using SPSS Version 15 and STATA 10.0. Associations between potential risk factors and the prevalence of FGM were explored using two dichotomous outcome measures: i) whether a woman herself had had FGM; ii) whether she had one or more daughters with FGM; using chi-square, t-tests and Mann Whitney U test as appropriate. Logistic regression modeling was used to investigate social, demographic and economic risk factors associated with FGM and formal tests for interaction were undertaken. Four models one for each of the main religious groups were undertaken for the logistic regression modeling, these were Protestant, Catholic, Muslim and traditional or animist. The following items were included: demographic variables: age (three 10 year age groups (15-24, 25-34, 35-49), urban versus rural living, region, ethnicity and religion), social variables: (any versus no education and responsibility for health care decisions (RHCD*)), and household economic status (asset index (divided into quintiles)). Tests for interaction between religion and each of the selected characteristics were also performed. Since the test for interaction between religion and education proved significant, subsequent analysis was stratified by religion (Table (Table22).
