Interest in the sexual behavior and reproductive health of adolescents in developing countries has increased since the early 1990s. The earliest studies of sexual behavior frequently examined factors associated with sexual experience, particularly individual-level factors, such as school attendance, educational attainment and knowledge of risk factors.^1,2 Later, research evolved to include broader contextual factors seen as influencing the experience and timing of adolescents' sexual transitions. Connectedness to family, schools, voluntary groups and peer groups, and the social norms governing these groups were also thought to be factors in young people's risk-taking behavior.^3,4

Studies in a variety of settings have demonstrated the association between positive family and peer connections and a decreased likelihood of sexual experience and potentially risky behaviors.^4–7 For example, in Ghana, parental regulation was inversely associated with the likelihood of young people having sexual experience.⁷ The effect of peer connections on sexual risk behaviors seems to be associated with the characteristics of the peers; adolescents whose friends model healthy behaviors are more likely to engage in those behaviors themselves.⁴ Social participation, as measured by membership in social groups and clubs, has been found to be associated with mainly healthy behaviors and lifestyles among adolescents in a number of settings, though an elevated risk of unhealthy behaviors is associated with membership in certain types of groups.⁸ For example, in one study in South Africa, compared with those who did not, females who belonged to sports clubs were less likely to be HIV-positive and more likely to negotiate protective measures, such as condom use. However, females taking part in local savings clubs that had periodic parties and included male members exhibited higher rates of casual partnerships.⁹ Thus, the norms and culture that govern social groups, rather than just membership in them, seem to influence adolescent behavior.³

Social Exclusion and Marginalization

If positive social connectedness is linked to healthy behaviors in adolescents, then social exclusion and marginalization may be predictive of poor outcomes. Social exclusion is defined as limited or no participation in social, economic and political life.¹⁰ Adolescent females report having significantly fewer friends than males and experiencing greater control of their movement and social interactions by others.¹⁰ Emerging evidence suggests that females who are isolated and marginalized may be more susceptible to sexual abuse. In a study in South Africa, females reporting few or no friends were six times as likely to have experienced forced sexual encounters as females reporting "many friends."¹¹

Adolescent Domestic Workers

One group often considered to be socially excluded and isolated is domestic workers, who are almost exclusively young and female.^12,13 Domestic work is considered to be among the types of work with the lowest status and the poorest pay,¹⁴ and the nature of the work keeps females inaccessible and socially isolated.¹³ Their workplace is a private residence, and within the domestic sphere, workers frequently work long hours for little pay, with few opportunities for social interaction.

Previous research in low-income areas of Addis Ababa, Ethiopia, found that many poor females were engaged in domestic work, working an average of 64 hours per week and earning an average of 52 birr (US$6) per month.¹⁵ Working long hours and being subject to control by their employers left them few opportunities for recreation, socialization or participation in available youth programs and services.^15,16 Among all categories of child workers, domestic workers are considered to be the most vulnerable to abuse, including physical and sexual violence;¹² anecdotal evidence and findings from qualitative data suggest that domestic workers may be more susceptible to abuse, both inside and outside the home.¹⁵ However, survey data provide no evidence that domestic workers experience higher rates of sexual abuse than other females.

Nonconsensual Sexual Initiation

A growing body of evidence suggests that nonconsensual or coercive sex is a common feature of adolescents' earliest sexual experiences, especially for females.^17–19 Sexual coercion is defined by Heise and colleagues as "the act of forcing (or attempting to force) another individual through violence, threats, verbal insistence, deception, cultural expectations or economic circumstances to engage in sexual behavior against her will.... The touchstone of coercion is an individual woman's lack of choice to pursue other options without severe social or physical consequences."²⁰ In addition, females who experience coerced or forced sex are more likely than those who do not to experience negative reproductive health outcomes such as STIs, unwanted pregnancies, miscarriage, low-birth-weight babies and depression.^18,21,22

In Sub-Saharan Africa, estimates of coerced sexual initiation range from 15% to 40%, perhaps in part because the way in which coercion is defined varies from study to study.^17,23,24 Most studies of sexual coercion among African adolescents focus on prevalence of nonconsensual sex or negative health or behavioral outcomes. However, few studies explore socioeconomic situations that may make specific subgroups of young women more vulnerable to sexual coercion.

This study explores the role of social exclusion in sexual debut. We examine factors associated with sexual debut that occurs very early (before age 15) and sexual debut that is nonconsensual. The study was undertaken in extremely poor urban settings in Ethiopia, where social isolation and exclusion are considered to be more pronounced.¹⁰

METHODS

Data for this study are from a population-based survey undertaken in mid-2008 of out-of-school female adolescents aged 10–19 in three Ethiopian cities. Addis Ababa is Ethiopia's capital, and Bahir Dar and Gondar are cities in the country's second-largest region, Amhara. Located in Ethiopia's northern highlands, Amhara has the highest rate of early marriage in the country and substantial rates of internal migration.^25,26 Slum areas of these three cities are the destination of many rural-urban migrants, including adolescents coming from rural areas of the country in search of better opportunities or escaping hardship, such as poverty, family disruption or forced early marriage. Previous research in slum areas of Ethiopia suggests that a large number of migrant females are absorbed into domestic work, frequently living in the household in which they work.¹⁵

Data Collection

In each of the three cities, two kebeles (the smallest administrative unit in Ethiopia) were selected. Because the study served as the baseline survey for a planned HIV- prevention project for out-of-school females, one of the kebeles would eventually serve as the intervention area for the study, and the other kebele would serve as control. Both the intervention and control kebeles were selected from the poorest areas of the cities, and were comparable in terms of the socioeconomic status and ethnic and religious composition of the population. However, control kebeles were not contiguous with intervention kebeles. Within the study areas of each city, 24 enumeration areas (12 in each kebele) were selected at random, with the assistance of the Ethiopia Central Statistical Agency.

In the first stage of the study, a census of the households in the enumeration areas was conducted. All household members were listed, along with their age, sex and relationship to the household head. Researchers suspected underreporting of resident domestic workers in previous population-based studies of adolescents. Therefore, the household listing included a special probe asking about usual members of the household, who may include domestic workers or other nonfamily members. This list of residents served as the sampling frame from which respondents were selected for the study. In each urban center, 666 households with out-of-school female adolescents aged 10–19 were selected for inclusion in the study. As the baseline for an intervention study, the sample size was calculated to detect an eight-percentage-point change in a hypothetical variable measuring 50% at baseline, and adjusted upward for 10% nonresponse. If a selected household had more than one respondent eligible for study, one female was selected for interview using a random number table.

Once the households were selected, trained female interviewers conducted visits to locate and interview the adolescents. If the respondent was not found at home on the initial visit, interviewers paid up to two additional visits to the household to locate her. There was no replacement of respondents who were not located. The interviewers were trained in techniques to ensure privacy during the interview process, such as conducting the interview at a distance from other people. Because the interviews took place during the day, guardians were frequently away at work, making it easier to provide privacy during the interview. Respondents were not given any form of compensation or payment for their participation. In some cases, employers of domestic workers resisted allowing the interview to take place. When this occurred, the research supervisors made several visits to these households to further explain the aims of the survey. Of the 1,998 female adolescents selected for interview, 1,837 were interviewed, a response rate of 92%.

Informed consent was obtained for all respondents. Among those who were younger than 18, consent was obtained from their resident parent or guardian. In addition, the study received ethical clearance from the authorized body in Ethiopia.

The questionnaire used in the study covered a broad range of topics, including household amenities and assets, education, social networks and mobility, migration, livelihoods, reproductive health knowledge and practice, marriage, births and sexual experience. The questionnaire was translated into Amharic and back-translated to ensure accuracy.

Measures

Dependent variables were sexual initiation before age 15, and nonconsensual sexual debut. The age of 14 was chosen as the cutoff for early sexual debut; a recent review suggested that those younger than 15 are generally not ready for most sexual, marital and reproductive transitions because of physiological immaturity, cognitive status and commonly held concepts of what is "old enough."²⁷ In the interview, respondents were asked the age at which they had first had sex; responses were dichotomized into younger than 15 and 15 or older.

Respondents who reported sexual experience were asked, "What were the reasons you first had sex?" Respondents were read a series of possible motivations for initiating sex that were both coercive and noncoercive, and were asked to identify those that applied to their first sexual intercourse; multiple responses were permitted. These responses were provided in order to make the respondent feel that she was not being singled out, and to imply that the experiences are not uncommon. The motivations were: "you wanted to show love," "you were curious about it," "because you felt obliged as a spouse/partner," "because you were tricked," "because the person insisted and would not take 'no' for an answer," "because the person threatened you," "because you were promised money or a gift" and "because you were physically forced." If the respondent reported trickery, insistence of a partner, threats, economic motivations or physical force as the reasons for their first sexual experience, they were coded as having nonconsensual sexual debut.* Those who reported sexual initiation motivated by love, curiosity, spousal obligation but reported no other coercive factor were considered to have had consensual sexual debut.

Independent variables in this study focused on the demographic and social conditions of young women that may make them vulnerable to early or coercive sex. Variables included were educational attainment, orphanhood status, marital status, alcohol use, being a migrant to the area, being a domestic worker and social exclusion. Age difference with the first partner was initially included in the model, but was found to have too many missing cases; 29% of females did not know the age of their first sexual partner.

To measure educational attainment, respondents were asked if they had ever attended school and the highest level of schooling they had attained, collected as a continuous variable. Responses were recoded as having never attended school or having attained 1–4 years, 5–8 years, or nine or more years of schooling for the table of sample characteristics to reflect the distribution of respondents' education. In bivariate and multivariate analysis, however, the continuous variable was used.

Orphanhood status was also recorded. Previous studies of orphans in Africa have demonstrated earlier sexual debut among young people who have lost one or both parents than among those who have two living parents.^8,28 Respondents were asked if their mother and father were alive or dead, and responses to these questions were used to create a variable reflecting whether the respondents had lost at least one of their parents. Alcohol use was measured by asking if the respondent had consumed alcohol in the last three months. Marriage was measured by asking respondents if they had ever been married. In addition, a follow-up question, "Have you ever been married but later divorced?" was asked to minimize underreporting of marriage by formerly married young women.

Previous studies in urban Ethiopia have underscored the increased vulnerability to social isolation and exploitation of rural-urban migrants in low-income urban areas.²⁹ Respondents were asked if they had ever moved from another region or from another location or district in the same region. Those reporting that they had moved from elsewhere were classified as migrants. Respondents were asked if they had ever done any work for pay and, if so, the type of work they were doing currently, or had done most recently. Respondents were coded as domestic workers (which included those who described themselves as cleaners or child-care workers) or not.

To capture social exclusion and isolation, we built a variable using a measure of friendship networks, community support and group participation. Respondents were asked how many friends they had, with a substantial proportion (56%) reporting that they had no friends. That fewer than half of our respondents reported having friends is consistent with other studies of females in extremely poor settings, especially females whose work involves long hours and little time for recreation and socialization.^15,30 To explore community support networks, two statements were read to the respondents and they were asked if they agreed or disagreed. The statements were: "If you needed money urgently, there is someone in your neighborhood from whom you could borrow money" and "If you didn't have a place to stay, there is someone in your neighborhood who would take you in." Finally, group participation was measured by asking respondents if they had participated in a community club or group in the last year. Respondents who reported having no friends, having no community support and not engaging in clubs or groups were coded as being socially excluded. Those with at least one friend, or who reported at least one type of community support or group participation were coded as socially included.

Analysis

Survey data were entered into the computer using CS-Pro, and converted to SPSS for analysis. The data were weighted by the number of eligible adolescent females in the household, to correct for the chance of being selected for the survey. However, in the majority of households (65%), there was only one eligible adolescent; in 25% of households, two eligible adolescents were present. Weighted data are presented for all results except the characteristics of the sample. Sample characteristics are presented for the entire sample, and separately by sexual experience. Because the dependent variables are early sexual initiation and nonconsensual sexual debut, the sample analysis of those outcomes was restricted to females who reported sexual experience and were aged 15 or older.

Descriptive analysis was used to compare those whose sexual initiation occurred during later adolescence (ages 15–19) with those whose debut occurred during early adolescence or childhood. Likewise, we compared those who had consensual sexual debut with those who were coerced. Tests for significant differences between subgroups included chi-square tests for categorical variables and t tests for continuous variables. Logistic regression was used to model the odds of early sexual debut and coerced sexual initiation.

RESULTS

Sample Characteristics

Four out of five survey respondents (81%) were aged 15–19 (Table 1). The bias toward older ages is related to the criteria that respondents be out of school at the time of survey. Among those interviewed, 34% had never attended formal school, 25% had had only 1–4 years of education and 22% had had 5–8 years; 19% of respondents had nine or more years of education. Eight percent of respondents were orphans, while 29% had lost one parent. The majority of females were migrants to the area (76%), which is consistent with other studies of adolescents in slum areas of Ethiopia.²⁹ Thirty-six percent of respondents were socially excluded, and 23% were sexually experienced.

Characteristics of Domestic Workers

Nearly half (48%) of this group of poor adolescent females were performing domestic work. Sixty-nine percent of out-of-school females had ever worked for pay; among those, 72% were doing or had recently done domestic work (not shown). Other jobs held by respondents were salesgirl at a shop or kiosk (6% of working females), waitress or barmaid (5%) and manual laborer (4%). All working females worked extremely long hours; domestic workers reported an average of 63.3 hours in the previous week and those doing other paid work reported an average of 61.1 hours. However, domestic workers earned roughly half of what females in other types of work received. On average, domestic workers earned US$8.20 in a month, compared with US$19 per month for females in other forms of work.

Compared with other workers, domestic workers tended to have started working earlier; domestic workers began working at a mean age of 14.4 years and those performing other paid jobs began at 16.2 years. Domestic workers also tended to be younger, less educated, less likely to live with their parents and more likely to be migrants than those doing other forms of work. While 24% of domestic workers in the sample were aged 10–14, only 2% of other working females were in this age-group; 49% of domestic workers had never been to school, compared with 13% of other working females. Ninety-eight percent of domestic workers had migrated to the area and 96% were not living with either parent, compared with 52% and 56%, respectively, of females engaged in other forms of work. However, domestic workers were less likely to be orphaned than other females in our sample, with 33% of domestic workers and 46% of other working females reporting having lost at least one parent.

Early and Coerced Sexual Experience

Twenty-three percent of the sample reported that they were sexually experienced, with females in Gondar (28%) and Bahir Dar (20%) significantly more likely to report sexual experience than those in Addis Ababa (14%; not shown). That females in the two cities in the Amhara region exhibit higher rates of sexual experience than those in Addis Ababa may reflect the higher rates of early marriage among females in this region. Among females with sexual experience, 27% experienced debut before age 15. Some 29% of sexually experienced females described their first sex as occurring under coercive conditions, which is consistent with other studies of nonconsensual sexual initiation.^31,32 The most common forms of coercion were the partner's not taking "no" for an answer (14%) and physical force (10%). Other forms of coercion, trickery, threats and economic coercion, were each reported by 4% of sexually experienced females.

Bivariate Analysis

Table 2 compares selected characteristics of females for whom sexual initiation occurred before age 15 or under coercive circumstances with those for whom it did not. Females for whom sexual initiation occurred during early adolescence or under coercive circumstances had significantly less schooling than those for whom sexual initiation occurred later or under consensual conditions.

Having ever been married was associated with having had early first sex, and with not having experienced coerced first sex. Among young women who had first had sex before age 15, 71% were ever-married; of those, 93% had first had sex with their spouse following marriage (not shown). Most married respondents (84%) reported that they had first had sex out of obligation as a spouse/ partner. Being a migrant to the area and being a domestic worker were both associated with early sexual initiation and coerced sexual debut. Likewise, being socially excluded was associated with both negative outcomes. In bivariate analysis, alcohol consumption was not associated with either outcome.

Multivariate Analysis

Among sexually experienced out-of-school females aged 15 or older, educational attainment was negatively associated with the odds of first sex that was early or coerced (odds ratio 0.9 for each; Table 3). Having been married was associated with decreased odds of coerced sexual debut (0.3).

Being a domestic worker was positively associated with both negative outcomes: The odds of early sexual initiation and coerced first sex for females who worked as domestic workers were significantly higher than for other young women (3.3 and 1.8, respectively). Females who were socially excluded had odds of coerced first sex twice as high as those who were not excluded (2.0).

DISCUSSION

This study attempted to understand the social conditions—including marginalization, exclusion and exploitive labor—that may make young women more vulnerable to early or unwanted sexual initiation. It may be that the characteristics of domestic workers increase their vulnerability. Domestic workers are dependent on their employers for survival, frequently living and working under the same roof, and earning exceedingly low salaries for long hours of hard labor. Because domestic workers are most often migrants, with few friends or relatives in the vicinity, they usually have no one to turn to for assistance or support; they may not understand or know to whom to report abuse or difficulties, and the very people they depend on for sustenance may be the ones exploiting them. The social exclusion of these workers make them easy targets for sexual abuse and exploitation, and their precarious situation, including dire poverty, means that they may be hesitant to report such incidents to authorities. Although many studies have surmised that domestic workers are more vulnerable to sexual exploitation, this is the first study, to our knowledge, that establishes that association through rigorous, quantitative methods. This study suggests that young females who are domestic workers may be more vulnerable to exploitation and abuse, including early and unwanted sex.

Limitations

This study, however, has a number of limitations. Only out-of-school females were eligible for the study; therefore, the study is not representative of all female adolescents in low-income urban areas of Ethiopia. In addition, sexual experience may be underreported, particularly in a setting such as Ethiopia, where a high value is placed on virginity until marriage.³³

This study was not able to include poverty as a measure of vulnerability to early or unwanted sexual initiation. Surveys such as the Demographic and Health Surveys, as well as this survey, measure wealth or poverty at the household level. A list of household assets or amenities is read to the respondent and he or she is asked if the household possesses that amenity; responses to these questions are used to build a measure of household wealth. However, such measurement may not be applied to domestic workers, who form a large proportion of our sample. Even when a household ranks high on a wealth measure, the domestic worker who resides in that household probably does not have access to that wealth and cannot be assigned the same level of wealth or poverty as her employers. In addition, we were able to measure only cash earnings and not in-kind payments. Pay for domestic workers typically includes food or shelter, and this study was unable to measure those benefits; sporadic provision of items made reporting of such data difficult.

Finally, the fact that this study was cross-sectional limits our ability to conclude that social exclusion or engagement in domestic work results in increased vulnerability to early or coerced sexual relations. Social exclusion and work were measured at the time of the survey, not at the time of sexual initiation, making it impossible to establish a causal linkage. Reverse causality is also possible, as females who experience early and unwanted sex may be excluded socially and be more likely to enter domestic service.

Conclusions

As in a number of other studies, no or low educational attainment was associated with increased odds of negative outcomes in this study. To address this risk factor, programs for female adolescents should build their social capital and inclusion, as well as provide opportunities for them to stay in school and obtain positive and nonexploitive forms of work. In Ethiopia, the Ministry of Youth and Sport and regional Youth and Sport Bureaus in Amhara region and Addis Ababa are implementing a program called "Biruh Tesfa" (Amharic for "Bright Future") in slum areas.^34,35 The program combats social exclusion in these areas by providing females with groups that meet weekly with an adult female mentor. Females considered eligible for Biruh Tesfa are out-of-school slum-dwelling females aged 10–19. They are recruited by adult female mentors who go from house to house to identify eligible females, including domestic workers. Once an eligible domestic worker is identified and she shows interest in joining the program, the mentor negotiates for her participation directly with her employer.

Group meetings include basic literacy and education on HIV, reproductive health and financial literacy. In addition, females in need of medical or legal services or shelter are referred to such facilities through the program. Although there was initial skepticism among public health professionals that programs could actually reach domestic workers, the scale of Biruh Tesfa suggests that reaching socially excluded females is feasible if the appropriate strategy is used. Since Biruh Tesfa began in 2007, over 10,000 females have benefited and an evaluation of the project is currently under way.
