Contraceptive use among the poor in Indonesia.

CONTEXT: Indonesia has experienced a dramatic increase in contraceptive use and an equally dramatic fertility decline over the last 30 years. Yet recent reductions in family planning funding, program decentralization and the diminishing role of the public sector as a service provider may lead to lower use among poor women. METHODS: The data for analysis were drawn from the 2002-2003 Indonesia Demographic and Health Survey. Bivariate techniques were used to compare overall contraceptive use, reliance on specific methods, source of supplies and reasons for nonuse of contraceptives between poor and better-off women. Multivariate regression assessed the association between use of a modern method and selected social, demographic and attitudinal characteristics. RESULTS: Better-off women wanted significantly fewer children than did moderately or extremely poor women (2.8 vs. 3.0-3.4), were more likely to approve of family planning (93% vs. 87-91%) and were more likely to believe their spouses approved (91% vs. 80-87%). Better-off women and moderately poor women had higher odds of using modern contraceptives than did extremely poor women (odds ratios, 1.6 and 1.4, respectively). Compared with women who gave a non-numeric response, those who wanted two or fewer children had higher odds of using a modern method (2.0). The odds were also higher among women who lived in a district in which the mean ideal number of children was below the national median (1.5). CONCLUSION: Governmental efforts to increase contraceptive use among poor women need to focus on changing attitudes toward smaller family sizes and family planning.

Reasons for not using condoms among female sex workers in Indonesia.

The aim of this study was to gather data on condom use among brothel-based female sex workers in Indonesia and to study the reasons for not using condoms in order to provide new and existing condom promotion programs with information to improve their performance. Quantitative data were gathered by KABP surveys (n = 1450) and a condom diary with a sample of 204 female sex workers. Qualitative data were collected by conducting focus group discussions and in-depth interviews among female sex workers and pimps. Around 53% of sexual intercourses were reported to be protected, and 12% of these protected intercourses were preceded by clients' argumentation against it. Only 5.8% of sex workers consistently used condoms for a 2-week period of observation, and this figure decreased to 1.4% for a 4-week period. Reasons for not using condoms from the clients' side, as mentioned by the sex workers, were perceived less pleasure due to the condom and the belief that clients that are acquainted with the sex workers do not need protection against sexually transmitted diseases (STDs) or AIDS. The main reasons of female sex workers for not using condoms were the beliefs that boyfriends, native Indonesians and healthy-looking clients cannot spread STDs. Another reason stated was that sex workers had already taken other preventive measures, like taking antibiotics. The research also showed that pimps were not very supportive of condom use programs in Indonesia. Condom unacceptability is an important reason for not using condoms for both clients and female sex workers, whereas pimps, who are in the best position to encourage condom use, unfortunately consider condom use as a threat to their business. For the successful introduction of consistent condom use, it is necessary to design interventions for both sex workers and clients and to provide appropriate educational materials and preferred brands of condoms. Also, pimps must be involved in intervention programs.

The current situation of the HIV/AIDS epidemic in Indonesia.

Until 1999 the known prevalence of HIV in Indonesia was low, except for isolated geographic groups exposed to Thai fisherman. Since then, the prevalence among injection drug users in rehabilitation centers in Jakarta has risen rapidly to approximately 45-48%, according to surveys in 2001. By 2002 the prevalence had risen to 8-17% among female sex workers, 22% among transvestite sex workers, and 4% among other male sex workers. Condom use is low in all groups, and there is considerable sexual mixing between risk groups. Surveys suggest that an increasing proportion of adolescents use drugs and have had sexual intercourse. Thus, although the epidemic in Indonesia is currently in the World Health Organization-defined "concentrated stage," all the ingredients for rapid spread are present. Intensive effective intervention strategies--condom use and clean needle use promotions--need to be implemented, especially in the high-risk groups, if a more serious epidemic is to be averted.

Voluntary HIV testing, disclosure, and stigma among injection drug users in Bali, Indonesia.

Recently, large increases have been noted in injection drug use and HIV prevalence in Indonesia. Because voluntary HIV counseling and testing can play an important role in HIV prevention, it is important to understand factors related to its use. The objective of this study was to identify factors related to the use of voluntary HIV testing among drug users. In-depth interviews were conducted with a sample of 40 drug users in the Denpasar area of Bali, Indonesia. Drug users may be interested in testing if they have enough information about AIDS to know that they are at risk and that they need this information to protect themselves and others from infection. Barriers toward testing included the fear of a positive result, fear of reactions from family and community members and stigmatization. Other obstacles include a feeling of hopelessness, problems with testing, unavailability and side effects of AIDS drugs and other factors. Many persons would not disclose their status to community members and sexual partners. There were serious concerns about others being ashamed of them and the impact of HIV on relationships with spouses and sexual partners and on employment.

A possible role for rusa deer (Cervus timorensis russa) and wild pigs in spread of Trypanosoma evansi from Indonesia to Papua New Guinea.

Movement of transmigrants and livestock from western Indonesia to southeastern areas of Irian Jaya near the border with Papua New Guinea may pose a risk of introducing Trypanosoma evansi into Papua New Guinea via feral Rusa deer (Cervus timorensis russa) and wild pigs which inhabit these areas in large numbers. Pilot experimental studies were conducted to observe infection in pigs and Rusa deer with a strain of T. evansi isolated in Indonesia. Parasitaemia and signs of clinical disease were monitored each second day for 120 days. Trypanosomes were observed in haematocrit tubes at the plasma-buffy coat interface of jugular blood of deer and pigs on 86% and 37% of sampling occasions respectively. Parasitaemia was at a high level in deer for 35% of the time but for only 11.5% of the time in pigs. Results indicate that both Rusa deer and pigs have a high tolerance for infection with T. evansi. The deer suffered mild anaemia evidenced by a 25% reduction in packed cell volume (PCV) 14 days after infection which coincided with the initial peak in parasitaemia. However, PCV had returned to pre infection values by the end of the experiment. The pigs showed no change in PCV. There were no visual indications of disease in either species and appetite was not noticeably affected. It was concluded that both Rusa deer and pigs were capable reservoir hosts for T. evansi but that Rusa deer, with their more persistent higher levels of parasitaemia, have more potential to spread T. evansi into Papua New Guinea from West Irian than pigs.

Monitoring of human enteric viruses and coliform bacteria in waters after urban flood in Jakarta, Indonesia.

Floodwaters in Kampung Melayu village, Jakarta, Indonesia, as well as river water and consumable water (including groundwater and tap water) samples in flooded and non-flooded areas, were quantitatively analysed to assess occurrence of viruses and total coliforms and E. coli as bacterial indicators after flooding event. High numbers of enterovirus, hepatitis A virus, norovirus (G1, G2) and adenovirus were detected at high concentration in floodwaters and waters sampled from Ciliwung River which runs across metropolitan Jakarta and is used widely for agriculture and domestic purposes by poor residents. One out of three groundwater wells in the flooded area was contaminated with all viruses tested while no viruses were found in groundwater samples in non-flooded areas and tap water samples. The results revealed that human enteric viruses, especially hepatitis A virus and adenovirus, were prevalent in Jakarta, Indonesia. This study suggested that flooding posed a higher risk of viral infection to the people through contamination of drinking water sources or direct contact with floodwaters.

The human behavioral and socioeconomic determinants of malaria in Bacan Island, North Maluku, Indonesia.

In eastern Indonesia, malaria control activities mainly depend on residual spraying but the situation is almost unchanged since the past decade. Understanding the socioeconomic and human behavior determinants is needed to implement an effective malaria control in accordance with the local condition and development. Hence we conducted an unmatched case control study. Two hundred samples were recruited from all, 11 villages surrounding the centre in Bacan Island, Maluku. For children aged 0 to 15 years old, the association of socioeconomic determinants: crowding and poor type of houses with malaria remained significant in the multivariate analysis. Meanwhile for persons above 15 years old, younger persons and regular going outside at night remained significant in the multivariate analysis. And for persons above 15 years old, a higher proportion of controls (14%) than cases (4%) slept under mosquito net regularly. The Indonesia Family Program should be promoted. There was a better quality of life in small family. For persons above 15 years old, going outside at night should be discouraged because exposed to mosquito bites. The malaria control strategy use of effective personal, regular use of mosquito net could be used as a completion for the present activities. Considering the low malaria knowledge among samples, inhabitants should be enhanced the malaria knowledge on causation, transmission, prevention and to provide proper knowledge on residual spraying.

Epidemiology of onychomycosis in Indonesia: data obtained from three individual studies.

In terms of both diagnosis and treatment, onychomycosis remains a problem in Indonesia. To examine this situation, we performed a retrospective study of the incidence of onychomycosis involving 10 state university hospitals across the country. We collected data from medical records of patients treated at these hospitals in 1997-1998 (study 1) and from a 1998-1999 multi-center Indonesian study on pulse-dose itraconazole therapy (study 2), both of which were part of onychomycosis campaigns with the objective of increasing the awareness of physicians of onychomycotic problems. Further, we analyzed data from year 2003 medical records of patients from 4 hospitals in Java (study 3). The average incidence of onychomycosis among fungal diseases increased to 4.7% in large cities that, from an average incidence within Indonesia of 3.5% in 1997-1998. At only 0.5%, the incidence of onychomycosis among all skin diseases was low in both study 1 and 3. Female patients outnumbered male patients with a ratio of 1.5:1 to 2:1. In study 2, the fingernail was the site most frequently affected. KOH examinations and fungal culture in study 1 (n=557) showed causative organisms to be Candida (50.1%), dermatophytes (26.2%), moulds (3.1%) and mixed infections (1.8%), with the remainder (18.7%) unidentified. Similar frequency of causative organisms was reported in study 2 (n=113) and in study 3 (n=183). People's low awareness of nail disease and consequent lack of concern as well as the limited diagnostic ability of KOH examination and fungal culture might influence the low incidence of the disease and the frequency of detection of the causative organisms.

Larvae of Anisakidae in marine fish of coastal waters near Jakarta, Indonesia.

Three species of marine fish were collected from the waters around Seribu Islands, near Jakarta, Indonesia, and examined for nematode larvae of the family Anisakidae. Larvae were found in 719 (49%) of 1.459 Rastrelliger kanagurta, 445 (50%) of 884 Decapterus russelli, and 217 (41%) of 531 Sardinella sirm. Larvae from a subsample of 150 infected fish, 44 R. kanagurta, 86 D. russelli, and 20 S. sirm, were examined microscopically and only Anisakis type I and Terranova type B larvae were found. In all three species of fish the Anisakis larvae predominated. The Anisakis larvae found in these fish are a potential source of infection for humans in Indonesia; however, human anisakiasis has not yet been reported from this country.

Intestinal capillariasis (Capillaria philippinensis) acquired in Indonesia: a case report.

We report a case of intestinal capillariasis in a 32-year-old Italian man. After he made a trip to Indonesia that lasted approximately one month, he developed heartburn, abdominal pain, irregular bowel movements, headache, fatigue, weight loss, low-grade fever, and severe itching. The diagnosis was provided by the recovery of Capillaria philippinensis eggs in the stool. Treatment with oral albendazole, 200 mg twice a day for 21 days, resulted in clinical and parasitologic cure. This is the first report of C. philippinensis infection acquired in Indonesia.

In vivo resistance to chloroquine by Plasmodium vivax and Plasmodium falciparum at Nabire, Irian Jaya, Indonesia.

A survey of resistance to chloroquine by Plasmodium vivax and P. falciparum was conducted during May 1995 at three mesoendemic villages 30 km southeast of Nabire, near the central northern coast of Irian Jaya, Indonesia. The prevalence of malaria at Urusumu (n = 157), Margajaya (n = 573), and Topo (n = 199) was 18%. 9%, and 9%, respectively, with spleen rates among children of 79%, 10%, and 27%. Infected patients among those screened formed a study population of 64 subjects eligible for a 28-day in vivo test of resistance to chloroquine. Sixty-three patients successfully completed the test; 45 males and 18 females 1-60 years of age, of whom 29 were Javanese transmigrants of five years residence in Irian Jaya and 34 were native to Irian Jaya. The seven-day day cumulative incidence of therapeutic failure for P. vivax and P. falciparum was 15% (n = 34) and 30% (n = 37). The 14- and 28-day estimates of cumulative incidence were 45% and 64% for P. vivax and 58% and 89% for P. falciparum. Almost all recurrences appeared in the face of ordinarily effective levels of chloroquine and its major metabolite, desethylchloroquine, in whole blood (> or = 100 ng/ml). Four infections by P. malariae in subjects enrolled in this study cleared by day 2 and none reappeared within 28 days. Chloroquine no longer provides effective therapy for falciparum or vivax malaria along the northern coast of Irian Jaya, Indonesia.

The first reported outbreak of dengue hemorrhagic fever in Irian Jaya, Indonesia.

During the months of September 1993 through February 1994, an outbreak of hemorrhagic fever occurred in the city of Jayapura, the provincial capital of Irian Jaya, Indonesia. Seventy-two patients (age range = 1-41 years) with suspected dengue hemorrhagic fever (DHF) were enrolled into the outbreak investigation conducted during October-November 1993. The pediatric patient population consisted of 36 individuals ages 1-12 years of age with a similar male to female ratio. From clinical histories obtained from the children diagnosed with DHF (n = 23), the predominant complaints were fever (100%), headache (96.7%), vomiting (47.8%), abdominal pain (39.1%), back/bone pain (39.1%), cough (39.1%), sore throat (21.7%), convulsions (17.4%), and eye pain (13.0%). Clinical findings of the same pediatric patients included a positive tourniquet test result (100%), thrombocytopenia (100%), hemoconcentration (100%), skin petechiae (43.5%), epistaxis (39.1%), and maculopapular rash (26%). All four of the children diagnosed with DHF grade IV had hepatomegaly, pleural effusion, ascites, cold perspiration, and confusion. Serologic data demonstrated that a majority (46 of 70, 68.7%) of the individuals assessed did not have significant levels of IgM specific for dengue viruses at the time of their admission. However, the nine successful dengue virus isolations were only from these serononreactive cases (19.6%). From the other patients assessed, 11.4% had a primary (or first exposure) serologic response to dengue virus antigen (predominantly IgM); 17.1% had a secondary (or subsequent exposure) serologic response to the same dengue antigens (predominantly IgG response) and 5.7% (four adults) had indeterminate serologic data that could not differentiate between reactivity to dengue or Japanese encephalitis virus antigen preparations. Virus culture of blood samples produced nine dengue virus isolates: DEN- 1 (2), DEN-2 (1), and DEN-3 (6). Japanese encephalitis and influenza viruses were not isolated from blood and pharyngeal specimens, respectively, from any of the patients. Thus, this first reported outbreak of DHF in Irian Jaya, Indonesia was found to be attributed to dengue viruses types 1, 2, and 3.

Adaptation of a chloroquine-resistant strain of Plasmodium vivax from Indonesia to New World monkeys.

The spread of chloroquine-resistant Plasmodium vivax from Papua New Guinea and Indonesia poses a serious health threat to areas of Southeast Asia where this species of malaria parasite is endemic. A strain of P. vivax from Indonesia was adapted to develop in splenectomized Aotus lemurinus griseimembra, Aotus vociferans, Aotus nancymai, and Saimiri boliviensis monkeys. Transmission to splenectomized Saimiri monkeys was obtained via sporozoites. Chemotherapeutic studies indicated that the strain was resistant to chloroquine and amodiaquine while sensitive to mefloquine. Infections of chloroquine-resistant P.vivax in New World monkeys should be useful for the development of alternative treatments.

Toxins and colonization factor antigens of enterotoxigenic Escherichia coli among residents of Jakarta, Indonesia.

Infection caused by enterotoxigenic Escherichia coli (ETEC) poses a serious health problem among children and adults in developing countries. Colonization of the small intestinal mucosa by ETEC strains is mediated by antigenically specific fimbriae, also known as colonization factor antigens (CFA). The significance of this study arises from reports that active and passive immunization with ETEC strains harboring CFAs has previously been shown to induce protective immunity against diarrhea in animal models. The aim of this study was to determine toxin-associated CFAs of ETEC isolated from a diarrheal disease case-control study in Jakarta, Indonesia. Thirteen hundred and twenty-three diarrheic and control patients with lactose-fermenting colonies were screened by ganglioside GM1-enzyme-linked immunosorbent assay (GM1-ELISA) for heat-labile (LT) and heat-stable (ST) toxins. Two hundred and forty-six (19%) ETEC isolates identified by GM1-ELISA for the LT/ST toxins were screened for CFAs by Dot blot assay using monoclonal antibodies against CFA/I, II, and IV and against the putative colonization antigens (PCF) PCFO159, PCFO166, CS7, and CS17. Of the 246 ETEC isolates, 177 (72%) elaborated ST, 56 (23%) produced LT, while 13 (5%) elicited both the ST and LT toxins. CFA testing of the 246 ETEC isolates showed that 21 (8%) expressed CFA/I, 3 (1%) exhibited CFA/II, 14 (6%) elaborated CFA/IV, while 7 (3%) expressed PCFO159 and PCFO159 plus CS5. No CFAs or PCFs could be associated with 201 (82%) of the ETEC strains. This report documents the types of CFAs associated with ETEC strains in Jakarta, Indonesia. These data may help current research efforts on the development of CFA-based vaccines for humans against ETEC and provide additional information for future ETEC vaccine trials in Southeast Asia.

Cholera in Indonesia in 1993-1999.

Cholera-specific surveillance in Indonesia was initiated to identify the introduction of the newly recognized Vibrio cholerae non-O1, O139 serotype. Findings from seven years (1993-1999) of surveillance efforts also yielded regional profiles of the importance of cholera in both epidemic and sporadic diarrheal disease occurrence throughout the archipelago. A two-fold surveillance strategy was pursued involving 1) outbreak investigations, and 2) hospital-based case recognition. Rectal swabs were transported to Jakarta for culture and isolates were characterized by serotypic identification. Outbreak findings showed that V. cholerae O1, Ogawa serotype, was the predominant etiology in all 17 instances of investigated epidemic transmission. Monitoring of eight hospitals representing seven provinces provided 6,882 specimens, of which 9% were culture positive for V. cholerae: 589 (9%) for O1 and 20 (< 1%) for non-O1 strains. Proportional representation of V. cholerae O1 among cases of sporadic diarrheal illness was variable, ranging from 13% in Jakarta to < 1% in Batam. Overall, 98% of V. cholerae O1 cases were the Ogawa serotype. There was no instance of non-O1, O139 serotype introduction in either epidemic or sporadic disease form. Anti-microbial drug susceptibility was consistently demonstrated, both temporally and spatially, except against colistin. Evidence is provided that epidemic and sporadic cholera occurrence in western Indonesia is associated with periods of low rainfall. Conversely, in the more eastern portion of the country, heavy rainfall may have contributed to epidemic cholera transmission.

Acute respiratory illness incidence and death among children under two years of age on Lombok Island, Indonesia.

No childhood pneumonia incidence data for Indonesia exist, and few data exist for Asia as a whole. From February 1, 1998, to January 31, 1999, we conducted acute respiratory illness (ARI) surveillance among children < 24 months of age in 50 mainly rural villages on Lombok Island, Indonesia. The total number of child-years at risk during the study period was 17,015. The documented incidences of simple, severe, hospitalized, and radiologically confirmed alveolar pneumonia were 21, 8.3, 5.3, and 1.8 per 100 child-years of observation, respectively. For all outcomes, the incidence was higher among younger and rural children. All cause and ARI-specific infant mortality rates were 84 and 33 per 1,000 live births, respectively. More than 65% of deaths due to ARI occurred outside of a hospital setting. The incidence of pneumonia is high in Lombok. Interventions should include introducing vaccines to prevent infections leading to pneumonia and increasing the access of critically ill infants to the health care system.

Evidence of Rickettsia typhi and the potential for murine typhus in Jayapura, Irian Jaya, Indonesia.

Murine typhus (etiologic agent: Rickettsia typhi) is endemic to Indonesia, especially on the highly populated island of Java. A survey of rodents from Irian Jaya, the eastern-most province of Indonesia, indicated striking geographic variation in risk factors associated with murine typhus. Murid rodents (n = 112) collected from two villages in the Arso district of northeastern Irian Jaya, were found to be free of ectoparasites normally associated with transmission of R. typhi (i.e., Xenopsylla cheopis). All rodents (n = 72) tested by enzyme-linked immunosorbent assay were negative for antibodies to R. typhi, whereas 12.5% (9/72) were positive for antibodies to Orienta tsutsugamushi. In contrast, both Rattus norvegicus and R. rattles (combined n = 87) from the harbor area of the provincial capital, Jayapura, were infested with flea ectoparasites. X. cheopis was found on 31 (35.6%) of the live-captured rodents. Serum samples from nine of 82 rodents contained antibodies reactive to R. typhi (11.0%). These data show for the first time that rodents exposed to R. typhi are well established in Jayapura, and that some of these rodents harbor fleas potentially capable of transmitting murine typhus and plague.
