STDS in women attending family planning clinics: a case study in Addis Ababa

For cultural reasons modern contraception has been slow to gain acceptance in Ethiopia. Knowledge about contraception and abortion is still limited in many family and community settings in which it is socially disapproved. By 1990 only 4% of Ethiopian females aged 15-49 used contraception. Little is known of sexually transmitted disease (STD) prevalence in family planning (FP) attenders in Africa in general and Ethiopia in particular, even though attenders of family planning clinics (FPCs) are appropriate target groups for epidemiological studies and control programmes. A study of 2111 women of whom 542 (25.7%) attended FPCs in Addis Ababa showed utilisation rates to be highest in women who were: Tigre (33%) or Amhara (31%), aged 20-34 years (30%), age 16 or older at first marriage/coitus (28%:38% in those first married after 25 years); who had a monthly family income of 10 Ethiopian Birr (EB) or more (33%:36% for those with income 100-500 EB), three or more children (37%), more than five lifetime husbands/sexual partners (39%); or were bargirls (73%) or prostitutes (43%). The seroprevalence rates for all STDs, higher in FPC attenders compared with other women, were syphilis (TPHA) 39%, Neisseria gonorrhoeae 66%, genital chlamydia 64%, HSV-2 41%, HBV 40% and Haemophilus ducreyi 20%. Only 4% of FPC attenders had no serological evidence of STD: 64% were seropositive for 3 or more different STD. Clinical evidence of pelvic inflammatory disease (PID) was also more common in the FPC attenders (54%), 37% having evidence of salpingitis. The FPC provides a favourable setting for screening women likely to have high seroprevalence of STD, who for lack of symptoms will not attend either an STD clinic nor a hospital for routine check up. We recommend that measures be taken to adequately screen, treat and educate FPC attenders, their partners, and as appropriate and when possible their clients, in an attempt to control STDs and ultimately HIV in the community. Social, economic and cultural factors in the occurrence of STDs, prostitution, family planning and modern contraception coverage in Ethiopia are identified and deficiencies of current programmes briefly discussed with the objective of targeting services more effectively.

Chlamydial infection in a population of Ethiopian women attending obstetric, gynaecological and mother and child health clinics

The prevalence of chlamydial infection was assessed in 1,846 Ethiopian women attending clinics in Addis Ababa. Sera were tested for type-specific anti-chlamydial antibodies using purified chlamydial antigens (C. trachomatis A-C (CTA-C), C. trachomatis D-K (CTD-K), Lymphogranuloma venereum (LGVI-3), and C. pneumoniae (CPn), in a micro-immunofluorescence (micro-IF) test. Three levels of chlamydial infection were established. Sera with: 1) antibodies to CTA-C, CTD-K, LGV 1-3 and CPn singly or in combination, are considered as evidence of overall exposure to chlamydial species (OEC); 2) antibodies to CTD-K and LGV 1-3 are considered as evidence of exposure to genital chlamydial pathogens (GENCI); 3) IgM titre > or = 1/8, or Ig G titre > or = 1/64 to CTD-K and LGV 1-3 alone or at a similar level with antibodies to CTA-C and CPn is considered as being evidence of active genital chlamydial infection (AGCI). OEC was found in 84 pc, GENCI in 60 pc and AGCI in 42 pc. Infection was highest in family planning and lowest in antenatal clinic attenders. OEC increased progressively with age while GENCI and AGCI peaked at ages 35 to 49. Chlamydial infection was highest in those married and sexually active < 13 years of age (OEC 88 pc, GENCI 69 pc, AGCI 49 pc); the lowest income groups (OEC 85 pc, GENCI 65 pc, AGCI 45 pc); those with more than five sexual partners (OEC 92 pc, GENCI 78 pc and AGCI 65 pc); with highest prevalence in bargirls (OEC 97 pc, GENCI 84 pc, AGCI 75 pc). Fifty pc had clinical evidence of past or present infection in the urethra, salpinges or bartholin glands (USB). OEC, GENCI and AGCI were associated with PID. The association of seropositivity with USB was remarkably similar for both gonorrhoea and chlamydial infection: we recommend adoption of a treatment regimen effective for both infections. The micro-IF test is a useful epidemiological tool for identifying the of antibodies to chlamydial pathogens. Use of antigen pools CTA-C, CTD-K LGVI-3 and CPn enables a distinction to be made between genital and non-genital infections. The problem of symptomatic and asymptomatic chlamydial disease needs to be addressed urgently.

Teenage obstetric and gynaecological problems in an African city

OBJECTIVE

To measure the prevalence of sexually transmitted diseases (STD), pelvic inflammatory disease (PID), cervical cancer, pregnancy and use of contraception in teenagers, and to determine socioeconomic factors associated with these conditions to aid planners of medical services and promotion of sexual health.

SUBJECTS

181 Ethiopian teenagers and 1,845 women aged 20 to 45 years for comparison.

SETTING

Gynaecological outpatient department, antenatal, postnatal and family planning clinics, in two teaching hospitals and a mother and child heath centre in Addis Ababa, Ethiopia.

METHODS

Results of serologic tests for STD, clinical evidence of PID, and cervical cytology were analysed against socio-economic factors.

RESULTS

In teenagers early age at first marriage/coitus, more common in those of rural origin, was associated with poverty, a greater number of lifetime sexual partners, and prostitution: 40 pc were first sexually active before the menarche. Prevalence of seropositivity to specific STD pathogens was; Treponema pallidum (TPHA) 21 pc, Neisseria gonorrhoeae (gonococcal antibody test: GAT) 40 pc, genital chlamydiae 51 pc, hepatitis B virus 36 pc, herpes simplex virus (HSV-2) 32 pc, and Haemophilus ducreyi 16 pc: 92 pc of teenagers were seropositive to one or more STD's. STD seroprevalence was higher in those with more than one sexual partner, those sexually active by age 15 (very high in those sexually active by age 12), those involved in prostitution and those attending the family planning clinic. Forty three pc had clinical evidence of PID; one married at age 10 had invasive cervical cancer by age 18; 40 pc of teenagers were pregnant compared with 25 pc of those aged 20 to 45; 21 pc attended for family planning; of regular FPC attenders 81 pc were GAT seropositive.

CONCLUSION

Despite legislation early age of sexual debut is common, STD and PID are widely prevalent, the pregnancy rate in adolescents is high and contributes to the national population growth rate. Action is required at family, medical and governmental level to encourage cultural acceptance that marriage and sexual activity should not occur before the age of 16 years, with education appropriate to culture to prevent STD. Similar studies are recommended in other countries to establish a baseline for informed strategy regarding prevention of STD and health education.

A socioeconomic, clinical and serological study in an African city of prostitutes and women still married to their first husband

The aim of this paper was to compare women involved in prostitution with a group of women still married to their first husband and reporting having had only one sexual partner, in order to ascertain what factors if any contributed to women going into prostitution or staying still married to their first husband, their only sexual partner, and thereafter to compare clinical and serological aspects of the gynaecological conditions of the women in these two groups. The role of prostitutes in transmission of sexually transmitted diseases (STD) is widely recognised. Socioeconomic factors determining whether a woman will drift into prostitution or have a stable first marriage are largely unknown as are prevalence rates of STD, pelvic inflammatory disease (PID) and cervical cancer in these women. A socioeconomic, clinical and serologic study is reported for 2111 Ethiopian women attending teaching hospitals and maternal and child health clinics in Addis Ababa, analysing basic demographic data of three groups of women: (i) 278 engaged in prostitution, (ii) 730 still married to their one and only sexual partner, and (iii) 1103 single, widowed, divorced or married to their second or subsequent partner. Thereafter groups (i) and (ii) were compared and contrasted with regard to further socioeconomic, clinical and serological associations. The most significant socioeconomic associations for women in prostitution were low income (95% had < 50 Ethiopian birr [< U.S. $25] per month), ethnic group, and the timing of first coitus in relation to the menarche (81% were first married by age 15), in that order. Women still married to their first sexual partner had higher income, higher age at first marriage and longer duration of marriage. Sero-prevalence rates of STD in prostitutes were high: gonorrhoea 88%, genital chlamydiae 78%, syphilis (TPHA) 62%, HSV2 and HBV 46%, and chancroid 19%: 67% had PID and 2.9% cervical cancer. In comparison, rates for women married to their first and only sexual partner were: gonorrhoea 40%, genital chlamydiae 54%, syphilis (TPHA) 19%, HSV2 33%, HBV 35%, chancroid 13%, PID 47% and cervical cancer 1%. While the very high prevalence of STD in women involved in prostitution is not so unexpected, the high rate of STD in women still married to their first and only sexual partner is indicative of male promiscuity. Control of prostitution and diseases spread by it, together with education of both men and women is a national priority.

Seroepidemiological and socioeconomic studies of genital chlamydial infection in Ethiopian women

OBJECTIVE

To measure the prevalence of chlamydial genital infection in Ethiopian women attending gynaecological, obstetric and family planning clinics; to identify the epidemiological, social and economic factors affecting the prevalence of infection in a country where routine laboratory culture and serological tests for chlamydial species are unavailable; to determine the risk factors for genital chlamydial infection in those with serological evidence of other sexually transmitted diseases.

SUBJECTS

1846 Ethiopian women, outpatient attenders at two teaching hospitals and a mother and child health centre in Addis Ababa, Ethiopia.

SETTING

Gynaecological outpatient department, antenatal, postnatal and family planning clinics.

METHODS

Sera were tested for type-specific anti-chlamydial antibodies using purified chlamydial antigens (C. trachomatis A-C (CTA-C), C. trachomatis D-K (CTD-K), Lymphogranuloma venereum (LGV1-3), and C. pneumoniae (CPn)), in a micro-immunofluorescence test. The genital chlamydia seropositivity was analysed against patient's age, clinic attended, ethnic group, religion, origin of residence, age at first marriage and first coitus, income, number of sexual partners, duration of sexual activity, marital status/profession, obstetric and contraceptive history, and seropositivity for other sexually transmitted diseases.

RESULTS

Overall exposure to chlamydia species was found in 84%, genital chlamydial infection in 62%, and titres suggestive of recent or present genital infection in 42% of those studied. Genital chlamydial infection was highest (64%) in family planning and lowest (54%) in antenatal clinic attenders. Exposure to genital chlamydia species was influenced by ethnic group and religion. Those married and sexually active under 13 years of age had greater exposure (69%) to genital chlamydial infection than those first sexually active aged over 18 (46%). Prevalence of infection was highest in those with more than five sexual partners (78%) and in bargirls (84%). The lowest income groups had a higher prevalence (65%) of genital chlamydial infection than the wealthiest (48%). Multivariate analysis showed the most important factors to be age at first coitus, religion, prostitution and present age of the woman in that order. Risk for genital chlamydial infection was increased in those with seropositivity for syphilis, gonorrhoea, HSV-2 but not HBV infection. CONCLUSION/APPLICATION: Chlamydial genital infections are highly prevalent in both symptomatic and asymptomatic Ethiopian women. The high prevalence of infection reported reflects a complexity of socioeconomic factors: very early age at first marriage and first coitus, instability of first marriage, subsequent divorce and remarriage or drift into prostitution, all of which are influenced by ethnic group, religion and poverty--together with transmission from an infected group of prostitutes by promiscuous males to their wives, lack of diagnostic facilities and inadequate treatment of both symptomatic and asymptomatic men and women. The problem of chlamydial disease in Ethiopia needs to be addressed urgently in the context of control of STD.

First coitus before menarche and risk of sexually transmitted disease

The prevalence of sexually transmitted disease (STD), pelvic inflammatory disease (PID), and cervical cancer, and the relation between these conditions were studied in 2111 Ethiopian women. Early sexual activity was associated with an increase in prevalence rates of STD and PID; possible aetiological factors include physical and immunological immaturity of the female genital tract and the number of sexual partners.
